Description

Switching structure and cable connector with switching structure

technical field

The utility model relates to a switching structure and a cable connector with a switching structure, in particular to a switching structure for a power line or a signal line and a cable connector with a switching structure.

Background technique

Commonly used cable connectors can connect a cable to various devices. With the development of the technology industry, many connectors continue to be developed for users to quickly connect, and more and more attention is paid to the protection of cable connectors. However, in the process of connecting cables, in addition to achieving basic good electrical connection characteristics, the connector body must have a certain bonding stress, but various external factors may cause the connector to loosen easily after long-term use. It causes the cables to separate from each other, causing their electrical connection to fail, and has potential safety hazards; and when the cable plug connectors are connected to each other, various types of sockets and plug connectors are developed in order to stably clamp the cable plug connectors, usually because Due to specification restrictions, a plug can only fit a single type of socket. The common socket connector shown in Figure 7 includes a longitudinal groove A33 of a plug connector A3 that guides the protrusions of another plug connector to connect and form a Electrical connection, and the threadless part A41 of an outer wire holder A4, when in use, an inner wire holder is screwed into the outer wire holder A4 to form a buckle effect; but the socket connector does not meet the requirements of the modern industrial society The purpose of high efficiency and multi-function may also cause material fatigue and structural wear due to long-term use, making the original tight-fitting function worse. Therefore, multi-purpose, high-efficiency cable connectors with simple operation and easy maintenance are even more important. .

Known technology such as U.S. Patent No. US7,727,021B2 "Connector having a plug, a socket, and tubular shield member with an elastic arm", as shown in Figure 8, the connector includes a plug connector B10 (Plug), the The plug connector B10 (Plug) includes a plug main body B11 (Plug main body), a plurality of cylindrical terminals B20 (Pin terminals), a plug wire holder B40 (Plug holder), a spring B49 (Coil spring), a stopper Component B45 (Slip-out preventing member), and a socket connector B60 (Socket), which includes a socket main body B61 (Socket main body), a plurality of tubular terminals B70 (Socket terminals), a socket wire gripper B90 (Socket holder), the plug connector B10 (Plug) can be plugged into a socket connector without a buckle groove, and can also be engaged with the socket connector B60 (Socket). The plug connector B10 ( When the Plug) wants to be engaged with the socket connector without the snap groove, the external thread of the plug connector B10 (Plug) is used to screw the internal thread of the socket connector without the snap groove, and when the plug connector B10 ( When Plug) wants to connect the socket connector B60 (Socket), the hook of the stopper element B45 (Slip-out preventing member) of the plug wire holder B40 (Plug holder) of the plug connector B10 (Plug) is used B47 (Engagement nail) enters the guide groove B83 (Recessed portion) and the fastening groove B84 (Caulking portion) of the inner cavity of the socket holder B90 (Socket holder), and compresses the spring B49 (Coil spring) at the same time, using the spring B49 ( The spring thrust given by Coil spring makes the plug wire holder B40 (Plug holder) and the socket wire holder B90 (Socket holder) firmly buckled, and the columnar terminal B20 (Pin terminals) of the plug main body B11 (Plugmain body) and The tubular terminal B70 (Socket terminals) of the socket main body B61 (Socket main body) forms an electrical connection, whereby one connector can be used for two types of socket connectors; but this cable connector is The spring is used as a switching and buckling structure. If the spring is used for a long time Sexual failure or displacement will lead to a decrease in the joint stress, resulting in the loss of switching and snap-in functions, and the problem of power transmission interruption is likely to occur after the connector joint is loose, which has potential safety concerns. In addition, the spring is in the plug connection In the inner cavity of the device, it is inconvenient to assemble, remove and maintain the cable connector, which does not meet the needs of convenience and high efficiency.

In view of this, the applicant of the present invention has devoted himself to research and developed a switchable structure and a cable connector with a switchable structure, in order to improve various deficiencies of the above-mentioned known technologies.
