Types of Wire Terminals

The definition of a terminal is:

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.

Wire Harness Manufacturing Terminals Include:

Ring

Spade

Hook

Quick-disconnect

Bullet

Butt terminals

Flagged

Wire terminals are available in insulated and non-insulated. 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

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 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.

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

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 (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.

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.

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.

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, electricity did not travel so safely through wires. Thankfully electricity 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.

You can take a look at wire insulation in the 19th century.

Wire Insulation Evolution

Due to increasing demand, electrical products require a solution to protect wires. The solution is affordable and efficient. Also, with the early growth in popularity, 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 have exploded since the early 20th century.

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.

Now that you know all about terminals and wires you need to know how they come together to create a wire harness.

Crimping Tools

We have over 30 years of wire harness manufacturing experience. Also, we here at Falconer Electronics have accumulated an impressive arsenal of crimping tools. When crimping wires and cables for our customers we have to utilize the proper tools. These allow our team to execute jobs with accuracy and efficiency. As well as, in a safe manner.

Many projects require crimping wires by hand. 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 great brand is Molex. They are a global leader in the manufacturing of high-quality electrical tools. They are also a leader in components and other equipment. Falconer Electronics hax relied on Molex for many years. We trust their products.

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. 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:

Accurate Labeling

Check for Damaged Insulation or Defective Wires

Continuity

Correct Wire Gauge

Also, Check for Proper Crimps

Free of Moisture and Corrosion

Optimum Wire Placement Within Connectors

Pull Test

Test for Broken Wires

Finally, Test for Shorts

Deming Values for Continual Improvement

Going old school, we are big fans of 20th-century management guru Dr. Deming. Dr. W. Edwards Deming created 14 points for management with a quest for continual improvement. We give credit to Dr. Deming for being the master of quality improvement. Particularly with his work in Japan during the 1950’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.

Two particular 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
