Cable connector with switching structure

The present invention relates to a cable connector having a switching structure, and more particularly to a cable connector having a switching structure for a power line or a signal line.

The conventional cable connector can connect a cable to various devices. With the development of the technology industry, many connectors are continuously developed for quick connection by users, and the protection of cable connectors is also receiving more and more attention. However, in the process of connecting the cable, in addition to the basic good electrical connection characteristics of the connector, the connector body must have a certain bonding stress, but various external factors may cause the connector to be loosened after long-term use. The cable is separated from each other, causing the electrical connection to fail, and has safety concerns; and when the cable plug connectors are connected to each other, various types of sockets and plug connectors are developed for stabilizing the cable plug connectors, usually because Specifications, a plug can only be used with a single type of socket, as shown in Figure 10. With the socket connector, it does not meet the high efficiency and versatility of the modern industrial society. It may also cause material fatigue and structural wear due to long-term use, which makes the original tight function go from bad to worse, so it is versatile and easy to operate. High efficiency cable connector connectors are even more important.

"Connector having a plug, a socket, and a tubular shield member with an elastic arm", as shown in FIG. 11, the connector includes a plug connector 10 (as shown in FIG. 11) (see U.S. Patent No. 7,727,021 B2). Plug), the plug connector 10 includes a plug main body 11, a plurality of pin terminals 20, a plug holder 40, and a spring 49 (Coil spring). a Slip-out preventing member 45 and a socket connector 60 (Socket) comprising a socket main body 61, a plurality of socket terminals 70, and a socket holding wire Socket holder 10, the plug connector 10 (Plug) can be plugged into the socket connector of the non-fastening slot, and can also be engaged with the socket connector 60 (Socket), the prior art When the plug connector 10 (Plug) is to be engaged with the socket connector of the non-fastening slot, the plug connector 10 (Plug) is used to thread the internal thread of the socket connector without the fastening groove, and When the plug connector 10 (Plug) is to be connected to the socket connector 60 (Socket), the plug is inserted. Head connector 10 (Plug) plug holder 45 (Slip-out preventing member) hook 47 (Engagement nail) enters the socket of the socket holder 90 (Socket holder) 83 (Recessed portion) and a caulking portion 84, at the same time compressing a spring 49 (Coil spring), using the spring force applied by the spring 49 (Coil spring) to make the plug holder 40 (Plug holder) and the socket The Socket holder 90 is firmly fastened, and the pin terminal 20 of the plug main body 11 and the socket terminal 70 of the Socket main body form electrical properties. By connecting, a connector can be used for the purpose of two types of socket connectors; however, the cable connector utilizes a spring as a switching and fastening structure, and if the spring is elastically disabled or displaced after prolonged use , the coupling stress is reduced, and the switching and fastening functions are lost, and the connector is easily released after the connector is loosened, which has the safety concern, and the spring is in the cavity of the plug connector. , inconvenient cable connector group Installation, dismounting and maintenance, does not meet the needs of convenience and high efficiency.
