Shielded connector component and plug thereof

Abstract

The invention relates to a shielded connector component and a plug thereof. A plug insulator is fixedly arranged in the inner hole of a plug shell. A plug contact is fixedly arranged in the plug insulator. A plug shield is sheathed on the periphery of the plug insulator. A gap is arranged between the front part of the plug shield and the plug shell. The front end part of the plug shield is provided with a reducing part which is matched with a reducing conical surface which is arranged at the front part of the plug insulator. An elastic claw which tilts inwards and freely extends forwards is arranged at the rear part of the plug shield. The free end of the elastic claw is resisting and pressing fit with a step surface which is arranged on the plug insulator. A press-connecting shield which is electrically connected with the plug shield is stuck on the rear end surface of the plug insulator. The press-connecting shield is in resisting and pressing fit with a sealing line structure which is arranged at the rear part of the plug shell. A socket contact is fixed in the inner hole of a socket shell through a socket insulator, wherein the inner hole penetrates through the front part and the rear part of the socket shell. The front part of the socket shell is inserted in the gap between the front part of the plug shield and the plug shell. The inner wall surface of the plug shell is in contact electrical connection with the plug shield.

Description

technical field [0001] The present invention relates to a connector assembly for current or signal transfer, in particular to a shielded connector assembly with an insulating shell for the plug, and also relates to the plug of the connector assembly. Background technique [0002] Usually, the shielding of the connector assembly is achieved through the connector shell. In this case, the shells of the plug and the socket are both metal. Both the plug shell and the socket shell have inner holes running through the front and back. The plug shell The inner hole of the body is provided with plug contacts through the plug insulator, and the inner hole of the socket is provided with socket contacts through the socket insulator. The plug contacts are wrapped in the plug housing, and the socket contacts are wrapped in the socket housing. When the plug After being mated with the socket, the mated plug contact and socket contact are completely enclosed in the metal plug housing and sock...

AI Technical Summary

Problems solved by technology

The use of metal to make the plug housing and socket housing will cause the overall weight of the connector assembly to be large. In addition, with the development of product miniaturization, the size of the connector assembly is getting smaller and smaller. The reduction in size makes the machining process requirements increase, resulting in an increase in the cost of the product. When the size of the connector assembly is reduced to a certain extent, it is difficult to form it by machining. In view of the above problems, in recent years, plug shells made of insulating materials such as plastics have appeared. Body and socket shell, the molding process of the plug shell and socket shell made of plastic is simple, easy to shape, and can get smaller parts. In addition, the plastic material has a better hand feeling, but the plastic shell has no shielding function. , additional shielding structure is required

[0003] However, the fixing between the shielding structure and the plug and socket is difficult to achieve, and the fixing between the shielding and the plug and socket is unreliable, and the shielding is easy to fall off in a vibration environment, resulting in poor anti-vibration performance of the connector
