Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a connector with an efficient plugging and unplugging self-locking device. Background Art

[0002] A plug-and-play connector is a device used to connect two wire harnesses, mainly for providing power supply and signal transmission to equipment, and is one of the commonly used electronic components in electronic devices. Currently, most of the existing plug-and-play connectors are usually composed of two matching plugs. The two plugs are respectively connected to two wire harnesses, and then the wire harnesses are connected through docking.

[0003] However, when the existing connectors are used for connection, some connectors do not have a self-locking function. If the connected wire harness is pulled or tugged, the connection is likely to be disconnected. For the other part of the connectors with a self-locking function, most of them use a self-locking buckle structure to achieve self-locking after insertion. When used in occasions where frequent plugging and unplugging are required, it affects the quick disassembly and replacement of the wire harness, and is relatively inconvenient to use.

[0004] Therefore, this application provides a connector with an efficient plugging and unplugging self-locking device to solve the above technical problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a connector with an efficient plugging and unplugging self-locking device to solve the problem that when the existing connectors are used for connection, some connectors do not have a self-locking function. If the connected wire harness is pulled or tugged, the connection is likely to be disconnected. For the other part of the connectors with a self-locking function, most of them use a self-locking buckle structure to achieve self-locking after insertion. When used in occasions where frequent plugging and unplugging are required, it affects the quick disassembly and replacement of the wire harness.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A connector with an efficient plugging and unplugging self-locking device includes a fixed socket and a straight plug. One end of the fixed socket is provided with a jack, a female pin core is arranged in the jack, a self-locking groove is opened on the inner wall of the jack, and a movable piece is movably installed on the fixed socket. One end of the movable piece is fixed with a top block and is placed in the self-locking groove. The other end of the movable piece extends out of the side surface of the fixed socket and is fixed with a pressing block;

[0008] One end of the straight plug is in plug-in fit with the jack. An activity groove is opened on the end surface of the straight plug. A clamping piece is hinged and installed in the activity groove. One end of the clamping piece far away from the hinge point elastically extends out of the activity groove and is in clamping fit with the self-locking groove.

[0009] Optionally, a cavity communicating with the bottom of the self-locking slot is formed in the inner wall of the fixed socket, and the middle part of the movable piece is elastically installed in the cavity of the inner wall of the fixed socket.

[0010] Optionally, a threaded portion is provided in the middle of the surface of the fixed socket, and a nut is sleeved thereon by threading.

[0011] Optionally, a positioning post is fixed to the inner side of one end of the clamping piece away from the hinge point, a return spring is sleeved on the positioning post, and the return spring is connected to the inner bottom of the movable slot.

[0012] Optionally, the return spring elastically pushes the end of the clamping piece out of the movable slot, and an obtuse angle is formed between the outer surface of the clamping piece and the surface of the straight plug.

[0013] Optionally, a plug body is fixed inside the straight plug, a male pin core is fixed to one end of the plug body, and the male pin core is inserted and matched with the female pin core.

[0014] Optionally, a housing is sleeved in the middle of the straight plug, a wire clamp is provided at one end of the straight plug away from the movable slot, a tail cover is installed on the wire clamp, and the wire clamp is electrically connected to the plug body.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the plug-in cooperation between the fixed socket and the straight plug, and thanks to the setting of the self-locking slot and the clamping piece, when the straight plug is inserted into the jack of the fixed socket, the clamping piece can automatically snap into the self-locking slot to form a snap connection and fixation, thereby completing the self-locking fixation between the fixed socket and the straight plug, and effectively avoiding the loosening caused by the harness being pulled or tugged.

[0017] At the same time, thanks to the cooperation of the self-locking slot, the movable piece, the top block and the pressing block, it is convenient to directly move the top block through the pressing block, so that the top block can push out the clamping piece in the self-locking slot, thereby quickly releasing the plug-in cooperation between the fixed socket and the straight plug, and effectively improving the disassembly and assembly efficiency, with simple operation and convenient use.

[0018] To sum up, the device of the utility model can not only facilitate self-locking fixation during wiring to avoid harness loosening, but also, when disassembling, assembling and replacing the harness, only need to press the pressing block to quickly release the self-locking connection between the fixed socket and the straight plug, which can improve the disassembly and assembly efficiency and is convenient to use.
