Automobile connector is an important part of automobile internal structure. It acts as a bridge between blocked or isolated circuits in the circuit. There are many kinds of automobile connectors, and almost more than 100 kinds can be used in general models. The main structure of automobile connector is mainly divided into four parts:

1、 Contact

Contact is the core component of automobile connector. It is mainly composed of male contact and female contact. The electrical connection is completed through the insertion of the two. The shape of the male contact is cylindrical (round pin), square cylindrical (square pin) or flat (insert) made of brass and phosphor bronze.

What is the composition and structure of automobile connector

The male contact is the jack, which is responsible for close insertion with the pin. There are many types of jacks, including folding type, cylindrical type, cantilever beam type, box type, hyperboloid spring, etc.

2、 Shell

The shell is also an outer cover, which provides mechanical protection for the built-in insulating mounting plate and pin, and provides alignment when the plug and socket are inserted, so as to fix the connector to the equipment.

3、 Insulator

The main function of insulator is to arrange the contacts as required and ensure the insulation between contact a and contact B. The material of insulator needs good insulation resistance, voltage resistance and easy processing.

4、 Attachment

Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring, sealing gasket, etc. Install accessories such as screws, nuts, screws, spring rings, etc. Most accessories include standard parts and general parts.
