Main components and specific functions of automotive connectors

The main function of the automotive connector is to connect between blocked or isolated circuits in the circuit to allow current to flow and allow the circuit to perform its intended function. Automotive connectors consist of four main components: housing, contacts, accessories, and insulators. The following describes the specific effects of these four main components of the automotive connector:

A. The housing is a cover of the automotive connector, which provides mechanical protection for the built-in insulating mounting plate and the pin, and provides alignment when the plug and the socket are inserted, thereby fixing the connector to the device;

B. The contact piece is the core part of the car connector to complete the electrical connection function. The contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed by the insertion of the female and male contacts. The male contact is a rigid part that is cylindrical (round pin), square (square pin) or flat (tab). Positive contacts are typically made of brass or phosphor bronze. The female contact, that is, the jack, is a key component of the contact pair. It relies on the elastic structure to elastically deform when it is inserted into the pin, and generates elastic force to form close contact with the male contact member to complete the connection. There are many types of jacks, such as cylindrical (grooving, shrinking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slotting, 9-shaped), box shape (square socket) And a double-curved wire spring jack;

C. Attachments are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, locating pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Install accessories such as screws, nuts, screws, coils, etc. The accessories are mostly standard and common parts;

D. Insulators are also often referred to as automotive connector bases or inserts. Their function is to arrange the contacts in the desired position and spacing and to ensure contact and contact and housing. The insulation properties between. Good insulation, combined snails at both ends.
