It is composed of the basic structural components of an automobile relay. The relay builds a communication bridge between the blocked or isolated circuits in the circuit so that the current can flow and the circuit can realize the predetermined function.
Composition of basic structural components of automotive relays
1. The shell, also called the shell, is the outer cover of the car connector. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides the alignment of the plug and socket when mating, and then fixes the connector To the device.
2. Insulators, insulators are also often referred to as car connector bases (base) or mounting plates (insert). Its function is to arrange the contacts according to the required position and spacing and to ensure that the contacts and the contacts are arranged. Insulation performance between the shell and the shell. Good insulation resistance, withstand voltage performance and easy processing are the basic requirements for selecting insulating materials to be processed into insulators.
3. The contact is the core part of the car connector to complete the electrical connection function. Generally, a contact pair is composed of a male contact piece and a female contact piece, and the electrical connection is completed by the insertion of the female and male contact pieces.
4. Accessories, which are divided into structural accessories and installation accessories. Structural accessories such as clamp rings, positioning keys, positioning pins, guide pins, connecting rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and common parts.
