Guide To Crimp Quality In Cable Harnesses

 

Cable harnesses are essential for connecting electrical and electronic components to guarantee effective and dependable performance in a variety of industries. These harnesses’ performance and longevity are directly influenced by the crimp quality used in them. This makes crimping among the most crucial steps when assembling cable harnesses. The process of crimping involves joining wires within a harness by attaching connectors to the ends of cables with a crimping tool. Many crimping steps, including stripping, cutting, and crimping the terminals on either side of the wires, can be automated. The correct crimping of wires, whether manual or automatic, is crucial because it creates a safe electrical connection and guards against problems like signal loss, voltage drop, and potential breakdowns.

The procedure

In a nutshell, the crimping procedure starts with the connector being placed in the crimping tool, followed by the exposed wire being inserted into the connector at the end of the cable, and then completed by installers squeezing the crimping tool’s handle to firmly link the connector to the cable. To begin, the wire is first properly put into the terminal’s barrel by first positioning the terminal in the crimp tool’s jaws. The crimp is then formed uniformly, without gaps or over-crimping, by applying pressure to the handles of the crimp tool. The final step is to confirm that the insulation crimp or the wings of the terminal have fully compressed around the wire insulation. When properly carried out, these steps result in effective crimping.

Advantages of crimping

Crimping is a quick and easy operation that can be automated using a crimping machine or done manually with crimping tools. It forms an airtight connection between the cable and connector to produce a union that is consistently dependable. Crimping is also consistent in comparison to other procedures like soldering, making it the best choice for applications that demand consistent durability even under the most trying circumstances. Crimping does have one possible drawback, though, namely the need for connector-specific tooling, which could result in high prices.

Why is it important to have good crimp quality?

When electrical components, such as cables and wires, are compressed with specially created splice bands or crimp terminations, gas-tight joints are created. A wire’s strands are reshaped by the resulting terminal to provide a solderless, low resistance electrical connection. To stop the corrosion of metals from oxygen and moisture, joints must be gas-tight. Additionally, they need to be sturdy, with a single joint that is free of splits or pieces. The crimping procedure makes all of this possible, while also making tiny connections in the wires that permit the passage of electrical current. Crimps of high quality can last for ten years or more.

How to ensure good crimp quality?

There are specific procedures that must be followed and certain criteria to be taken into account in order to guarantee a good crimp quality that has them lasting for up to a decade or longer.

Choosing the right crimp tool

The first step in assuring perfect crimps is choosing the right crimp tool. The wire gauge and termination size should be compatible with the tool. Purchasing a high-calibre, accurately calibrated crimp tool will enhance precision and uniformity throughout the assembly process.

Proper terminal selection

For a reliable crimp, choosing the appropriate terminal for the wire size and application is crucial. Terminals are made of a variety of materials, including copper, aluminium, and stainless steel. It is essential to make sure the insulation and conductor of the wire are compatible with the terminal.

Accurate wire stripping

For correct crimps to be achieved, wire stripping must be accurate and constant. To remove the proper length of insulation, a high-quality wire stripper that is compatible with the wire gauge needs to be used. Poor crimp quality might result from excessive or insufficient stripping.

Regular calibration and maintenance

To achieve accurate and consistent crimps, calibrating and maintaining crimp tools is required. By preventing under- or over-crimping, calibration guarantees that all crimps adhere to the necessary standards. The tool’s lifespan is extended by routine maintenance, which also lowers the possibility of subpar crimps.

Rigorous quality control and inspection

Implementing a stringent quality control procedure that involves checking crimps mechanically and visually is crucial. Compression, strain relief, and appropriate orientation all need to be checked visually. The integrity of the crimp is guaranteed through mechanical testing, such as pull force testing. Also, cutting and inspecting a crimped sample to determine its quality aids in identifying problems like inadequate compression or structural flaws in the crimp.

Training and certification

Operators who have received proper training are more likely to produce reliable, high-quality crimps, which lowers the possibility of errors like using the wrong wire ratio, overtightening, or not tightening the clamp enough. This is why you should always approach trained and certified personnel for having your cables crimped.

While it is true that all three share the ability to transmit data or electronic power between two points, as you will see below, each option has certain features and advantages of its own.

Why choose these options?

Cable assemblies, wire harnesses, and wire looms are all phrases that are used to refer to a grouping of various cables or wires that are connected or bonded together into a single unit. The advantage of this design is that each wire or cable can be created to precisely the appropriate length and size, and they are all grouped together in a precise fashion to avoid wasting space or adding more wiring and to make installation quicker and simpler.

Manufacturers who need to make hundreds or thousands of similar pieces of equipment frequently employ such assemblies. As a result of the constant vibration created by the automotive sector, single wires and cables were initially made popular in the 1920s and 1930s.  The wires were more protected and secured, according to the engineers, when they were tied together. Today, the majority of equipment uses a harness, assembly, or loom to organize its internal wiring.

Wire harness

These wiring systems are the most basic. A wiring harness is used to organize numerous wires as per a predetermined arrangement. A wire harness is simply a wrapper or sheath that keeps numerous wires or cables in place neatly, which is typically constructed of thermoset or thermoplastic material. To conserve space and shield them from harm while in operation, many wires of the necessary length are tied together. They might or might not have one or more connectors to terminate them. A more complicated harness might include wires running in several different directions and have a wide variety of termination components. Simple and complex harnesses both use materials like heat shrink, cable ties, or electrical tape to bind the wires together. These harnesses can typically be constructed relatively simply, which allows for speedy production at an affordable price.

The main purpose of a wire harness is to retain the cables and wires in the predetermined arrangement, minimizing movement and maximizing the use of available space while relying on the cable or wires' own sheath for protection. As a result, wire harnesses are typically a low-cost alternative. A wiring harness has the advantages of keeping the wires neatly in place, making them visible for easy fault tracing, and strengthening the assembly by binding the wires.

When the same wiring arrangement is used repeatedly, like during the mass production of items, this kind of wiring system is especially useful. The automotive industry popularized wire harnesses in the 1920s and 1930s to solve the issue of individual wires coming undone and getting damaged from the vibration of the car.

Cable assembly

A cable assembly is comparable to a wire harness, but its protective wrapping is more robust, and can be composed of vinyl, thermoplastic rubber, or shrink-wrapped thermoplastics. When exposure to environmental elements is a design consideration, a cable assembly is utilized to hold the wires or cables in place as well as to provide further protection against heat, abrasion, friction, and moisture. Individual wires and multicore cables can both be used in a cable assembly's design. The benefits of the protective wrapping against the weather are the main justification for choosing a cable assembly over a wiring harness, even if it is more expensive and loses the ability to physically trace the individual wires.

Wire loom

Wire looms are fundamentally more complicated than assemblies and harnesses, as they combine various cables and wire kinds into various groupings, frequently employing a variety of binding techniques. Wiring looms can range from being simple, integrating only a few wires, to being a complicated network of cabling, as those used in contemporary automobiles and aircraft. By lowering the wiring footprint of a product, wire looms offer space-saving as well as cost-saving designs by reducing material waste. Additionally, wire looms enable partial or full drop-in solutions for applications such as those in automobiles, aviation, and home appliances. This can significantly shorten installation timeframes and lower overall expenses.
