Wire harnesses are groups of wires or cables that are assembled, normally within a protective casing. In addition, these wire harnesses are also found in a lot of devices such as, automobiles, computers, toys, etc. Since wires need to be attached correctly within a harness, it's crimping that secures them in the right way.
Crimping is a method for joining two pieces of metal, typically used for connecting wires together in a wire harness. Crimping is done with a machine that tightens the two metal pieces together. This creates a solid connection, enabling high throughput of electricity to flow through the wires.
A good crimp is essential as it ensures good contact inside a harness. Poorly crimped connections can be weak. That means current may not be able to flow as well, or the wires may become separated. This can lead to problems, such as a car that refuses to start or a toy that doesn’t work.
A common mistake made when medical cable manufactureres is not exposing enough wire for crimping. If covering is still remaining too much, crimp terminal may not connect well. A second is the use of the wrong size crimp terminal for the wire. Use the appropriate size terminal to deny a good connection.
Here are some simple checks you can do get started testing crimped wire harness. To start, tug on the wire gently to test if it’s crimped tightly, and doesn’t come loose. A multimeter can be used to measure the connectivity to ensure electricity can pass through the connection freely. Finally, check the crimped connection for any signs of damage or weakness.
