Simple and understandable knowledge of automobile harness terminals

The automobile harness terminal provides the whole of maintenance equipment for a specific load group, such as trunk line Heat exchanger Control system, etc. The basic research content of telephone service theory is to study the relationship between traffic, call loss and harness capacity. Therefore, automobile harness terminal is an important basis in telephone service theory. This paper focuses on the definition of automobile harness terminal Composition Selection of materials and materials;

I Definition of automobile harness terminal

A communication bridge is built between two or more isolated electronic circuits, so that the current can flow and realize various functions of various electronic components. It is an indispensable component in all kinds of electronic equipment.

II form

Signal line: injection molding is required.

General harness components include: wire, terminal and plastic parts.

The composition of the composite harness also needs additional: tape, tie, sleeve, sheath, label, etc.

The quality of the beam material directly affects the quality of the harness, and the selection of the harness material is related to the quality and service life of the harness. Therefore, we must not be greedy for cheapness in the selection of harness products. Cheap harness products may use inferior harness materials.

So how can we know whether the quality of the harness is good or bad? Have some knowledge of automobile harness terminal materials. The following four points are the data of harness material selection, which is generally composed of conductors Insulating sheath The wiring terminal is composed of wiring terminal and wrapping materials. As long as you know these materials, you can easily distinguish the quality of outgoing harness.

1. Selection of harness conductor materials: select corresponding conductor materials according to the service environment.

2. Select insulation and sheath materials: the sheath material (plastic products) generally adopts PA6 PA66. ABS. PBT. PP et al. Flame retardant or reinforcing materials can be added to plastics according to the actual situation to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement.

3. Selection of automobile harness terminal materials: the copper used for wiring materials (copper parts) is mainly brass and bronze (the hardness of brass is slightly lower than bronze), in which brass accounts for a large proportion. In addition, different coatings can be selected according to needs.

4. Selection of wrapping material: the harness is coated with wear-resistant material Flame retardant Corrosion protection Prevent interference Reduce noise To beautify the appearance, wrapping materials are generally selected according to the working environment and space size. Tape is generally used as wrapping material Bellows PVC pipe, etc.
