Connector and plug thereof

Abstract

The invention relates to a connector and a plug thereof. The plug comprises a plug insulator which is equipped with a plug low-frequency contact installation cavity which runs through front end and rear end of the plug insulator, and the plug low-frequency contact installation cavity is equipped with a plug low-frequency contact, a plugging end of the plug is front end, the plug low-frequency contact comprises a contact sheath which is equipped with a contact head inserted in front of the plugging end of the plug, the other end of the contact sheath is equipped with a welding pin, a spring isarranged between the welding pin and a positioning face opposite to the contact head, and a rear end of the contact head in the contact sheath is equipped with a contact head springing motion space. The connector can automatically regulate axial direction and radial tolerances during connection.

Description

technical field [0001] The present invention relates to a connector, and also relates to a plug used for the connector. Background technique [0002] In microwave communication equipment, high and low frequency signals need to be transmitted. In order to meet the fast connection of high-frequency and low-frequency signals and avoid the problem of too many wires in the equipment caused by separate routing of high-frequency and low-frequency signal lines and difficult wiring, a connector for printed boards has appeared on the market. The connector includes plugs and The socket, the plug and the socket are respectively rigidly fixed with a high-frequency contact piece and a low-frequency contact piece. When in use, the plug and the socket are welded to the circuit board through the welding end of the high-frequency contact piece and the welding end of the low-frequency contact piece respectively, and the high-frequency and low-frequency signal transmission between the two circ...

AI Technical Summary

Problems solved by technology

However, since the high-frequency contact and the low-frequency contact are respectively rigidly fixed in the plug and the socket, when there is a radial and axial tolerance between the two circuit boards of the welding plug and the socket, the high-frequency contact on the plug and the socket The low-frequency contacts will no longer be coaxial with the high-frequency contacts and low-frequency contacts on the socket. At this time, when the connector is plugged in, it is easy to cause bending damage to the high-frequency and low-frequency contacts, which reduces the plug-in life of the connector. , affecting the performance of the entire connector
