What is a Wire Harness Manufacturer? 

A Wire Harness Manufacturer is a company or business that provides services to complete the wire harness assembly process. A wire harness is an assembly of wires, cables and connectors that transmit electric power or signals. Complete on site services include cutting, stripping, crimping, soldering, as well as the assembly of wires in a wide range. A wire harness assembly maximizes efficiency by binding wires together in a safe and secure routing pattern with the use of wire management products has as tie wraps, PVC, slit loom tubing and a wide range of sleeving.

The industry standard for Wire Harness Manufacturers is the IPC-620 Certification. An IPC Certified Wire Harness Manufacturer trains people in accordance to these standards and have process controls in place to monitor; soldering , stripping, crimping, securing, etc. necessary to ensure full compliance of wire assemblies to this standard. The IPC-620 Standard prescribes industry&#;s best practices and requirements for the manufacture of cable and wire harness assemblies. 

Additionally, the IPC-620 standard describes materials, tests and [visual] acceptability criteria for producing crimped, mechanically secured, soldered interconnections and the &#;all encompassing&#; related assembly activities associated with cable and wire harness assemblies.

Types of Wire Terminals 

The Definition of a Wire Terminal:

A device designed to terminate a conductor that is to be affixed to a post, stud, chassis, another tongue, etc., to establish an electrical connection.

Wire Terminals come in many different shapes and sizes. This is due to the size of the wire and screw. Also, there are several types of terminals.

Types of Wire Harness Manufacturing Terminals Include:

Wire terminals are available in insulated as well as non-insulated. Yet, the insulation provides a protective cover. Therefore, serving as a non-conductor. Furthermore, the type of project that is being done will determine if you need insulated or non-insulated terminals.

The insulation spares the wire from water and moisture as well. Also, it protects against extreme heat or cold. Wire insulation is typically available in vinyl, nylon and heat shrink.  Non-insulated terminals provide much more economic value with its low cost. Also, they are commonly used when extra protection is unnecessary.

When purchasing various Types of Wire Terminals, make sure that your purchase meets industry standards as well as project requirements.

Wire Terminals

Ring Terminals

A ring terminal is a round-ended terminal that easily allows a screw or stud to be attached. Ring terminals also called ring connectors, come in various sizes. It is crucial that the ring terminal is compatible with the wire gauge and stud size. Ring Terminals are either crimped or soldered to the wire. Available in insulated or non-insulated.

 

Spade Terminals

Spade Terminals are also called spade connectors or fork terminals due to the shape of the terminal. A spade terminal is available in various sizes depending on the gauge of the wire and stud size. Additionally, the open-ended spade terminal is convenient to use allowing easy attachment or removal from the screw. Especially for wire harness projects that are tight on space for installation. They are also available in insulated or non-insulated.

 

Hook Terminals

Similar to the Spade Terminal, Hook Terminals are also convenient to use with an open end (imagine a tiny version of Captain Hook). Likewise, these terminals are produced as insulated or non-insulated. Hook Terminals offer a simplistic yet durable connection for a variety of projects as well.

 

 

Quick-Disconnect Terminals

A quick-disconnect terminal provides convenient and reliable usage while also offering an easy connect and disconnect between two wires. They are commonly found in auto, industrial and consumer products. Products can be insulated or non-insulated. Quick-Disconnect Terminals additionally deliver a stable and durable connection.

 

Bullet Terminals

Bullet Terminals (also called bullet terminals) make an easy, reliable and secure connection. It is simple to disconnect as well. Bullet terminals also connect with the male and open-ended round female connectors creating a high-quality connection. Therefore, the connection with bullet terminals helps prevent corrosion and other potentially harmful materials from entering a wire harness.

 

Butt Terminals

A Butt Terminal connects or terminates single or multiple wires. Butt Terminals help prevent abrasion and cutting. Additionally, this extra protection helps keep out moisture, corrosion, and other negative elements. Butt Terminals serve as a simple solution to extend wires due to the ability to mate and connect wires. Simply install each wire on the open end of the connector, then crimp both ends of the terminal to secure the connection.

 

Ferrule Terminals

 

Fastening, joining, sealing, or reinforcing wires to each other. Ferrule Terminals can be used in many different applications. This is due to the many different types.

Flagged Terminals 

Flag Terminals also called flag connectors to offer a convenient and secure connection. Flag terminals work well in tight spaces as well as when a quick-disconnect is too large. Provides a quick and easy connection and disconnect. Also available in insulated and non-insulated.

 

 

Terminal Insulation Type 

Insulated

• Partially Insulated- Usually on ring or fork terminals. Used mostly to prevent crossing/ shorting of the wires. This is done by preventing contact with other wires.
• Fully Insulated- Mostly on Quick Connect/ Disconnect terminals. Fully insulated terminals are mostly used to prevent contact. This contact is between terminals. Therefore, the wires would not be in contact with each other in small spaces.

Uninsulated

• Terminals that need to be crimped in place. Also, terminals that need to be soldered in place. Usually, are finished with heat shrink tubing.

Wire Types 

• Stranded: When a wire needs to be flexible with a product.

• Flexible Ground Braid: Grounding connection between two terminals. Still has the ability to move or vibrate.

• Ribbon Cable &#; Gray: Usually used to make connections between electrical devices. Devices such as computers, DVD players, or hard drives.

• THHN &#; Solid: For a fixed application. For example, traveling through the straight formed conduit.

• THHN &#; Stranded: For an application where a flexible wire is needed. As in placing wire around corners or in power boxes.

Wire Insulation

Wires can be found&#; seems like&#; everywhere. Any electrical product that demands a current flowing will typically require a wire (or cable). Even when you hear something is &#;wireless&#;. In this instance wires power the device sending a signal. Electricity traveling through wires bring each of us tremendous joy and pleasure.

Examples of electronics containing wires:

• Computers
• Internet routers
• Also, music players (MP3 and iPods)
• Communication devices (Cell Phones)
• Vehicles
• Appliances

Actually, can you imagine surviving a single day without electricity? Well, in the early stages of electricity, currents did not travel so safely through wires. Thankfully electricity now travels safe and sound through wires protected with wire insulation.

The explosive growth of electrical products well over a century ago drastically increased the use of wires carrying electricity. Unfortunately, uncovered or exposed wires were responsible for dangerous situations.

Furthermore, exposed wires led to electrical shocks or fire. However, the addition of a non-conductive cover was a brilliant move to protect and strengthen wires. The application of Wire Insulation protects wires greatly reducing potential hazards and threats.

Let&#;s take a look back at wire insulation in the early stages.

Wire Insulation Evolution

Due to increasing demand for electricity in the 19th century, electrical products needed a solution to protect wires from potential hazards. The solution needed to be affordable and efficient.

Insulation became the viable and effective answer. Insulation serves as a non-conductor. The Insulation also separates and protects wires within a wire harness assembly. Especially since it is a nasty world out there with many detrimental elements that can cause harm to non-insulted wires.

To save the day, an insulated jacket protects each wire from the elements keeping the wire cozy and safe. Like insulated terminals, wire insulation also protects from moisture and extreme temperatures.

Thankfully wire insulation today is much more efficient. It is also, effective and affordable.  For example, thermoplastic high heat-resistant nylon coated wire (THHN wire) is low in cost. It is also lightweight. Due to these factors, it is an extremely popular wire insulation option.

In addition, loose wire also needed  organization. Therefore, the wire harness assembly has become necessary. It is much more efficient in harnessing loose wires. This is opposed to a &#;free for all&#;. Especially for electrical consumer goods and the auto industry both of which exploded in demand during the early 20th century.

Wire Insulation for Wire Harness Manufacturing: Five Common Types

Wire insulation is critical. Especially, in wire harness manufacturing. This is due to the way most harnesses are made up of wires. These wires are attached to each other. Without the insulation separating the raw strands of wire from each other wire harnesses would short out. This could cause damage due to contact.

There are five types of wire insulation that are most commonly used for wire harness manufacturing applications. All of them have similarities. However, they are used for different types of projects. Therefore, below we have listed each of these insulation types. Also listed is what they are best used for.

1) Polyvinyl Chloride (PVC)

 

Found in all of the major types of wire and cable.

Examples include:

• Low voltage building wire insulation and jacketing.
• Low and medium voltage equipment cable jacketing.
• Also, control cable jacketing.
• Indoor telecommunications cable.
• Automotive wire.
• Finally, flexible Cords.

PVC is fire and scratch resistant. Therefore, PVC can resist flames, oils, and sunlight. As well as, ozone pollution. Furthermore, these attributes are why it is considered a &#;general-purpose&#; material.

2) Fluorinated Ethylene-Propylene (FEP)

 

This is a melt-processible copolymer. It is made of tetrafluoroethylene and hexafluoropropylene. Also, FEP has dielectric properties in addition to chemical inertness and heat resistance. This is as well as, being weather resistant. Also, it is tough and flexible.

3) Polyethylene

 

Is lightweight, water-resistant, and is chemically inert.

 Different types of polyethylene:

• Low-density (LDPE).

• Linear low-density (LLDPE).

• 
  Advanced Photoelectric Camera vs. Fixed Caliper: Which Data Logs Better?

  Medium-density (MDPE).

• High-density (HDPE).

• Chlorinated polyethylene (CPE).

• Cross-linkable polyethylene (XLPE).

Polyethylene is a perfect choice for insulation of wires that will be used in projects that are considered &#;high voltage&#;. Especially for things involving radio frequencies, or audio projects. Due to its low dielectric constant, there is a decrease in electrical loss. Also, polyethylene&#;s low dielectric constant allows for a low rate of electrical charge being stored.

4) Nylon

 

Is a very flexible wire insulation. Also, it is usually extruded over softer insulation compounds.

Several Key components:

• Tough.
• Strong abrasion.
• Additionally, it is chemical resistance.

5) Thermoplastic Rubber

 

Has the ability to stretch to moderate elongations. Also, it will return to its near original shape. Therefore, creating a longer life. Furthermore, it has a better physical range than other materials

 Properties of Thermoplastic Rubber:

• Higher processing speeds.
• Wider usable temperature range.
• In addition to, excellent heat and weather resistance. As well as, age resistance without curing.

Wire Harness Manufacturing Tools 

Crimping Tools

With over 30 years of wire harness manufacturing experience, we have accumulated an impressive arsenal of crimping tools. When crimping wires and cables for our customers it is critical to utilize the proper tools. These tools allow our team to execute jobs with accuracy and efficiency as well as in a safe manner.

This is especially important due to many projects requiring crimping wires by hand. Furthermore, when producing wire assemblies for prototypes and small volume runs, handheld crimping tools sure come in&#;well&#; handy.

It is extremely important to look over the entire assembly when selecting the proper tool. For example, a basic pliers-style crimp tool can fit various wires, connectors, and terminals. Also, matching the right size tool is imperative when terminating wires.

A fantastic brand with Wire Harness Manufacturing is Molex. They are a global leader in the manufacturing of high-quality electrical tools. Molex serves as a market leader in components and other equipment. Our team trusts and relies on Molex tools on a daily basis.

The team at Molex declares they solve challenges &#;through our collaborative process, we take a multi-dimensional approach that brings together engineers, product designers, and manufacturers to ensure the design cycle is smooth and seamless.&#;

Below is one of the &#;Bad Boys&#; from Molex that our team loves to use when tackling tough projects:

Pneumatic Crimping Tool

Not interested in crimping wires by hand? Or do you have a large amount to crimp? No problem. Pneumatic crimping tools are extremely beneficial and efficient. Additionally, a pneumatic tool allows you to work hands-free due to air power. These tools are also fast and accurate. All qualities that will drastically increase your production.

We recently welcomed a new addition to our team. The Pneumatic Crimping Press pictured below. The &#;Plug&#;n Play&#; Pneumatic Press looks fierce, doesn&#;t it? It is ready and raring to CRIMP!! Especially ideal for wires requiring interchangeable crimping dies:

 

Tips for Successful Wire Harness Manufacturing 

• The crimp does not break the insulation.

• Also, the crimp fully wraps around and supports insulation (also cannot expose an opening greater than 45 degrees).

• Insulation does not have puncturing to the point where tabs penetrate the wires.

• Crimp tabs are in contact with the top of the insulation.

• Insulation is flush with the crimped wire.

• Additionally, identifying damaged insulation that reveals wires.

• The wire, connector, assembly process, as well as insulation, are all compatible

  .

Wire Harness Manufacturing: Crimping Wires Do&#;s & Don&#;ts

The IPC/WHMA-A-620  standard provides the necessary guidance on crimping wires. Consequently, this standard shows what is acceptable along with what is considered defective. Here are a few examples of Do&#;s and Don&#;ts:

Do&#;s

• Insulation crimp tabs fully wrap and support insulation
• Additionally, the insulation fully enters and extends past the insulation crimp tabs
• Wires must be in solid working condition &#; also cannot have scrapes, nicks, severing or other damages
• The connector retains the wires
• Center the crimp indent
• Insulation crimp must provide a minimum side report of 180 degrees

Don&#;ts

• Wires should not have deformities- Flattening untwisting, buckling, or kinking
• Insulation should not show any signs of pinching, pulling, fraying, discoloration, or charring
• Also, the insulation crimp needs to fully support and wrap insulation without causing any damage or breaking the insulation
• No broken insulation- This can expose wires causing safety issues and potential hazards
• Wire not secured by crimp
• Contact has visible cracks and fractures
• Also, no Birdcaging &#; Wire Separation

These are just a handful of the requirements.

Wire Harness Manufacturing Quality Control  

Wire Harness Quality Control is paramount at Falconer Electronics. We perform testing on cables and wire harness assemblies for every order. Therefore, quality control strongly impacts the bottom line with the wire harness assembly process. Also, our well-guided wire harness quality control and a solid test system prevents unnecessary errors, stress and lost profits.

High accuracy during the assembly process is the key to maintaining competitive pricing and reliability. We take every step to ensure accuracy at the time of assembling and producing the wires. Instituting a strict wire harness quality control system during production brings significant benefits to our customers.

Wire Harness Manufacturing Testing Check List

Safety First! Wire Harness Testing requires extreme caution. This is due to it involving live wires. Unfortunately, electric shock and burns can turn a great day into a really bad day quickly. It is mandatory to use personal protective equipment on the job such as safety glasses when testing a wire assembly.

When performing Wire Harness Testing, our quality control department strictly follows the IPC/WHMA-A-620 Standard. Most importantly, this standard is a collection of visual Quality Acceptability Requirements for Cable as well as Wire and Harness Assemblies.

Wire Harness Manufacturing Checklist for Testing Wires:

1. Accurate Labeling
2. Check for Damaged Insulation or Defective Wires
3. Continuity
4. Correct Wire Gauge
5. Also, Check for Proper Crimps
6. Free of Moisture as well as Corrosion
7. Optimum Wire Placement Within Connectors
8. Pull Test
9. Test for Broken Wires
10. Finally, Test for Shorts

Deming Values for Continual Improvement

Going old school, we are also big fans of 20th-century management guru Dr. Deming. Dr. W. Edwards Deming created 14 points for management with a quest for continual improvement. Especially since Dr. Deming is credited with being the master of quality improvement. Particularly with his work in Japan during the &#;s.

The Deming Institute continues the incredible legacy of Dr. Deming.

Furthermore, one of the core values at the Deming Institute states:

We are dedicated to the Deming philosophy and the belief that working together, with humility, we can make a difference in the quality of life for everyone.

This is a truly inspiring message!

According to Dr. Deming, implementing the 14 points is a philosophical way of conducting business with an unwavering quest for continual improvement. In addition, new tactics and behaviors become habits. Furthermore, those habits eventually form into the core beliefs and culture of a company.

 

In particular, two interesting points from Dr. Deming&#;s 14 points that help drive our wire harness quality control:

1. Create constancy of purpose toward improvement of product and service, with the aim to become competitive and to stay in business, and as a result to provide jobs.

5. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs.

Consequences when continual improvement and quality are NOT the top priority:

• High defect rates
• Underutilized equipment
• Poor productivity
• Poor inventory management
• Safety concerns
• Finally, low morale with employees

 

 

Measuring Standards for Wire Harness Manufacturing

When measuring wires for wire harness manufacturing there are two standards. Both of which need to be considered. Also, there are many different gauges. There are also, many sizes that are related to each of these two standards. What are the two standards for measuring wire?

• American Wire Gauge or AWG
• British Standard or SWG

Why does it matter that there are two standards for measuring wire?

Due to the differences between the two standards we have defined them both. Additionally, we have compiled their differences. We have also compiled their similarities.

American Wire Gauge (AWG)

AWG is the American Standard for measuring wire in wire harness manufacturing. This is useful for single wires as well as for wire harnesses.

The American standard is measured by an electrical wire&#;s diameter, as we stated in a previous blog AWG Wire Gauge Standard Vs. SWG Wire Gauge Standard.

Generally, when you measure anything the larger the object, the larger the measurement. However, that is not how wire measurements work. It is also, not how gauges work.

The physical size is what matters most. Also, the larger the physical size of the wire the smaller the wire gauge. This is according to the AWG measurements.

British Imperial Standard Wire Gauge (SWG)

In The United Kingdom legalized a standard for measuring wire used in wire harness manufacturing. They called it the British Imperial Standard Wire Gauge or SWG. However, what makes this standard different from the American Wire Gauge? All of the measurements are in metric sizes. Also, The United Kingdom rounds up their sizes to full numbers. Meanwhile, the American Standard does not. Due to this, there are issues. These issues are with the accuracy of wire sizes. Furthermore, wires that come from countries that use this measurement system are not always the correct sizes.

How AWG and SWG are Different in Wire Harness Manufacturing 

There are some significant differences such as the American standard is calculated in inches. Meanwhile, the British standard is measured in millimeters. Therefore, below are examples of measuring plates. Also, there is a calculation chart. Both of these are helpful. Especially when trying to measure a wire&#;s gauge for wire harness manufacturing. Something that is most noteworthy is, the differences that can be seen in the chart. Due to SWG sizes being rounded to whole numbers there are obvious differences in the gauge measurements.

How AWG and SWG are Similar 

in Wire Harness Manufacturing 

As previously stated, the two measurements types in wire harness manufacturing are different. However, AWG and SWG have similarities. such as both are determined by the physical size of the wire. Also, there is a correlation between the two standards. Therefore, the numbers that are calculated for the wire sizes are similar. Finally, both standards have developed similar devices for measuring the size of the wires.

 

Wire Harness Manufacturing: Calculating Wire Gauges

There is a mystery of Wire Harness Manufacturing. It is why wire gauge sizes are expressed in what seems to be a backward fashion. For example, the largest physical size that is seen on the measuring plates above is a size zero. Usually, zero is seen as a very small. It is an almost non-existent number. However, in wire gauges, it is the largest number. Why is this? Wire gauges seem to be expressed backward, which is due to wire drawing.

The Importance of Wire Drawing

Wire drawing is a similar practice to taffy pulling. The only difference being, it is done with wire instead of candy. This is to make it into the desired size for wire harness manufacturing. Therefore, the gauge is how many &#;operations&#; the wire drawing process takes to get to that size.

For starters, this process decreases wire gauge which also decreases the current that can move through the wire. Due to this decrease in current, there is also a decrease in the amount of amperage that smaller gauge wire can carry.

How to Choose the Best Wire Gauge for Your Wire Harness Manufacturing Project

Wire harness manufacturing projects can be complicated. However, there are helpful tips that ease some of the stress. For instance, as we previously mentioned wire gauges can affect the projects that you are working on. Furthermore, below are some helpful questions and tips.

**Due to the use of electricity when working with wiring please consult a professional to assist or inspect any final projects**

1:

What type of project are you doing? 

First, there are many different types of wire harness manufacturing projects. Depending on whether you are working on home wiring or building your own robot, there is a difference between what type of wire is required. For example, some projects include:

• Home wiring
• Robotics
• Computers
• Vehicles
• Appliances

Each of these projects can also require different gauged wiring. Therefore, depending on the current or amperage required, wire that you have on hand may not be adequate. Due to the different specifications and needs, some projects may require a smaller gauge of wire. However, that can lead to other issues.

2: How much space do you need for wiring?

To begin with, different housings will vary in size. Due to the wire size, the space needed to house them will also vary. For example, if you think about a light switch. Some have a single switch. Therefore, they only need enough room for the wires of that one switch. However, there are switches that have multiple switches. For that reason, the space required for the wiring of a multi-switch receptacle is larger than that of a single switch receptacle.

Consequently, in order to do a wire harness manufacturing job properly, you need to be aware of a few things. For example, how much space do you have to work with? Also, how much space do you need? Also, if you are working on home wiring that requires a larger current as opposed to a robot that requires less current. The space needed is different because the wire size will be different.

3: How are wire gauges calculated?

As a reminder, as wire increases in physical width, the gauge of that wire will decrease in numerical value. While this does seem backward it&#;s really not. Due to the previously mentioned wire drawing process, the number of operations to get it to that physical size is the gauge of wire. As a result, gauges are larger or smaller than the physical size. Also, the gauge specifications will depend on what type of measuring system was used.

 

4: What are large and small gauged wires used for?

There are also many different gauges of wire used for wire harness manufacturing. Consequently, they have many different uses.

Uses for some smaller gauges (larger physical sizes) of wire:

• Electrical lines (like those you see outside attached to power lines).
• Heavy duty automobiles. This like trains and larger armored trucks.
• Also, Home Wiring.

Uses for some larger gauges (smaller physical sizes of wire):

• Computers.
• Radios.
• Phones.
• GPS.
• Along with, MP3 players.

5: H

ow much amperage do you require?

Finally, there are different factors that determine the required amount of amperage for wire harness manufacturing projects:

• Amperage= Wattage/Volts
• What current do you need for your project?
• Where the wire is going?
• Also, where the wire is coming from?

In conclusion, the chart below will be helpful in deciding which wire is appropriate for your specific job.

Terminal Stud Sizes 

 

Why is the Terminal Stud Size Important in Wire Harness Manufacturing?

In addition, your assembly may require that wires are attached by screws or additional hardware. In this case, you need to be sure that you have a proper size to fit the hardware you are using.

Therefore, if you are using a 1/4&#; screw in your assembly but you have gotten a #2 terminal stud you won&#;t be able to attach your wire to your assembly. As you can see in the figure below, the sizes are very different.

Another important thing to remember is they have to be able to fit your screw or hardware. This means that a 1/4&#; terminal stud will actually be slightly larger than a 1/4&#;.

 

Wire Harness Manufacturing Challenges

Finally, every customer project requires precise Wire Harness Assembly accuracy. Furthermore, if you are working with a wire harness that is not working properly, there are several issues that can be causing the problem. 

Pinpointing the culprit causing the failure is the first step. Some failures reveal easily and immediately. Meanwhile, others may take some time to figure out. For example, damaged wires beneath insulation can be difficult to detect. Furthermore, stress on the wires may cause damage which may occur without actually breaking the insulation. Additionally, there can be no damage or contact deformation. 

Therefore, wires that carry electricity cannot withstand a pull beyond weight limitations. However, wires pulled at an excessive weight will cause breaks in the wires and this may occur without damaging the insulation. Furthermore, damaged or broken wires underneath a circuit board can be an extremely frustrating find.
