The Main Components And Specific Functions Of Automotive Connectors

The main function of car connectors is to connect between blocked or isolated circuits within the circuit, allowing current to flow and enabling the circuit to achieve predetermined functions. The automotive connector consists of four main components, namely: the shell, contact parts, accessories, and insulation. Below is an introduction to the specific functions of these four main components of automotive connectors:
A. The shell is the outer cover of a car connector, which provides mechanical protection for the insulated mounting plate and pins inside, and provides alignment when the plug and socket are inserted, thereby fixing the connector to the device;

B. Contact parts are the core components of automotive connectors that perform electrical connection functions. Generally, a contact pair is composed of a positive contact and a negative contact, and the electrical connection is completed through the insertion and connection of the negative and positive contacts. The positive contact part is a rigid part, and its shape is cylindrical (circular pin), square cylindrical (square pin), or flat (insert). Positive contacts are generally made of brass and phosphor bronze. The female contact piece, also known as the socket, is a key component of the contact pair. It relies on the elastic structure to undergo elastic deformation when it is inserted into the contact pin, generating elastic force and forming close contact with the male contact piece to complete the connection. There are many types of jack structures, including cylindrical (slotted, necked), tuning fork, cantilever beam (longitudinal slotted), folded (longitudinal slotted, 9-shaped), box (square) and hyperboloid linear spring jack;

C. Accessories are divided into structural accessories and installation accessories. Structural accessories such as snap rings, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, screws, spring coils, etc. Most attachments have standard and universal parts;

D. Insulators, also known as automotive connector bases or inserts, are used to arrange the contacts in the required positions and spacing, and to ensure the insulation performance between the contacts and between the contacts and the shell. Good insulation, with combination screws at both ends.
