Harness (collection of wires and cables)

A wiring harness is a device that binds multiple wires or cables together to form a whole. They are usually used in electrical equipment, automobiles, aerospace and other fields to transmit power or signals. The production of wire harness needs certain technology and tools. The following will introduce the manufacturing steps of the wiring harness and the required materials and tools.

Step 1: Prepare.

First, we need to prepare the necessary materials and tools. Materials include wires or cables, insulating sleeves, insulating tapes, etc. Tools include wire stripping pliers, wire pressing pliers and insulation wire stripping pliers. Ensure that all tools and materials are clean to ensure the quality of the wiring harness.

Step 2: Measure the peeling.

First, measure the length of each wire or cable with a measuring tool, and leave a certain margin. Then, one end of each wire or cable is stripped of a certain length of insulation with a wire stripper to expose the internal metal conductor. Ensure that the stripping length does not exceed the required length, so as not to affect the performance of the harness.

Step 3: Assembly

Next, assemble the stripped wires or cables according to the design requirements. First, the conductors of each wire or cable are classified according to color or mark. Then, the wires with the same color or mark are tied together with insulating tape to form a whole. Ensure that the binding is firm and prevent the wires from loosening or short-circuiting.

Step 4: heat preservation treatment.

After assembly, insulate the wire harness with insulating sleeve or tape. First, put an insulating sleeve or tape on the outside of the wire harness to cover all the wires. Then, the insulation layer is heated by using a heat-shrinkable sleeve or a heat-shrinkable tape, so that it closely fits the wiring harness and provides additional protection.

Step 5: Quality inspection

After the insulation treatment is completed, check the quality of the wire harness. First, check whether the harness looks neat, loose or damaged. Then use multimeter or testing instrument to test the resistance and insulation resistance of the wiring harness to ensure that the performance of the wiring harness meets the requirements.

final result

The production of wire harness is a process that requires skill and experience, but as long as the correct steps are followed, high-quality wire harness can be produced. Through reasonable assembly and insulation treatment, wire harness can provide stable and reliable power or signal transmission, which is widely used in various fields. When making wire harness, we must pay attention to safe operation to avoid accidents such as electric shock or short circuit. I hope that through the introduction of this article, I can have a certain understanding and understanding of the production of wire harness.
