Four basic structural components of automobile connector

Automobile connector is a kind of component that our electronic engineers often contact with. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The form and structure of automobile connector are changeable. It is mainly composed of four basic structural components: contact, shell (depending on the variety), insulator and accessories.

1、 The contact part is the core part of the automobile connector to complete the electrical connection function. Generally, the contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed by inserting and closing the negative and positive contacts.

The positive contact is a rigid part, and its shape is cylindrical (round pin), square cylindrical (square pin) or flat (insert piece). The positive contacts are generally made of brass and phosphor bronze. The female contact, namely the socket, is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when it is inserted with the pin to produce elastic force and form close contact with the male contact to complete the connection. There are many types of jack structure, including cylinder type (split slot, necked), tuning fork type, cantilever beam type (longitudinal slot), folding type (longitudinal slot, 9-shaped), box type (square jack), hyperboloid spring jack and so on.

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

3、 Insulator, also known as base or insert of automobile connector, is used to arrange contacts according to the required position and spacing, and ensure the insulation performance between contacts and between contacts and shell. Good insulation resistance, voltage resistance and processability are the basic requirements for selecting insulating materials to be processed into insulators.

4、 Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap ring, positioning key, positioning pin, guide pin, connecting ring, cable clamp, sealing ring, gasket, etc. Install accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories are standard parts and general parts.

It is these four basic structural components that enable the automobile connector to act as a bridge and operate stably.
