The relay sets up a bridge of communication between the blocked or isolated circuits in the circuit so that the current flows and the circuit achieve the predetermined function.

Basic structural components of automotive relays

1. 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 pins and provides alignment when the plug and socket are inserted, thereby fixing the connector. to the device.

2. Insulators, insulators are also often called automotive connector bases or inserts. Its function is to arrange the contacts in the required position and spacing and to ensure the Insulation performance with the shell. Good insulation resistance, withstand voltage performance and ease of processing are the basic requirements for selecting insulating materials to be processed into insulators.

3. The contact piece is the core part of the automobile connector to complete the electrical connection function. Generally, a contact pair is formed by a male contact piece and a female contact piece, and the electrical connection is completed by the insertion of the female contact piece and the male contact piece.

4. Accessories and accessories are divided into structural accessories and installation accessories. Structural accessories such as retaining rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Mounting accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and general parts.
