Circuit group provides the overall number of service equipment for a certain load source group, such as trunk lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and harness capacity, so wiring harness is an important basic concept in traffic theory. This paper mainly explains the definition of wire harness, the composition of wire harness, the material of the harness, and the selection of harness material;
First, the definition of wiring harness
It is an indispensable component of various electrical and electronic equipment to build a bridge of communication between two or more isolated electronic circuits, so that the current can flow and realize the functions of various electronic components.
Second, the composition of the wiring harness
Signal harness: injection molding is required.
The components of ordinary wiring harnesses are: wires, terminals, plastic parts.
The composition of complex wiring harnesses should be added: tape, cable ties, casing, sheaths, stickers, etc.
