Today, the world of connectors will explain the structure, materials and detailed functions of the four parts of the car connector:
1. The first thing to talk about is the housing of the car connector. The housing is also the outer cover, which provides protection. The insulating device board and pins built in the car connector need the housing to provide mechanical maintenance. In addition, it can help the plug and The socket is aligned and secured to the connected device.
2 . The contact piece is the central part of the automobile connector to complete the electrical connection function. Usually 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. Speaking separately, the male contact has three shapes: cylindrical, flat, and square. It is also a rigid part, generally made of brass and phosphor bronze. The female contact is the jack, and the jack is a very important part. The elastic structure of the jack will generate elastic force when the pin is inserted, and this elastic force will make the jack and the male contact more tightly inserted. Jacks are also divided into: cylinder type, cantilever beam type, tuning fork type, box type, folding type, hyperboloid wire spring jack, etc...
3.Accessories are divided into structural accessories and device accessories. Structural accessories such as retaining rings, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Device accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories have standard parts and general parts;
4.The insulator is also often called the car connector base or the device board (insert). Insulation function between. Good insulation, using combination screws at both ends.
