[0002] Energy storage connectors are key components for connecting battery energy storage packs in series and parallel. They mainly consist of a plug and a socket. During battery pack switching, the plug and socket of the energy storage connector are used for separation or insertion. The stability and reliability of the insertion or separation of the energy storage connector depend on the quality of its locking structure, which can even directly affect its electrical connection performance. Currently, there are many types of locking structures for energy storage connectors on the market, resulting in high manufacturing costs, poor user experience, poor stability during rapid insertion and removal, and most of them are glued together, making them prone to loosening.

[0006] A socket, one end of which is a locking end, and the locking end has a locking groove on its outside;
[0007] The plug is compatible with and detachably connected to the socket. It has a button mounting hole and a key slot. A button is installed in the button mounting hole, and a spring is installed in the spring mounting hole. A main body clip is located on one side of the button, and a key clip is located on the other side. The main body clip fits into the latch groove, and the key clip fits into the key slot. The button is installed in the button mounting hole via the spring. One end of the plug fits into the latch end, and this end of the plug is detachably connected to the latch end. The main body clip is detachably connected to the latch groove, and the key clip is detachably connected to the key slot.
[0008] By adopting the above technical solution, this utility model has the following beneficial effects:
[0009] This utility model includes a plug, socket, main body buckle, locking groove, key buckle, and key hole, etc. The overall structure is simple, easy to manufacture and process, and convenient and quick to assemble and use. Compared with the prior art, no glue is used. The main body buckle, locking groove, key buckle, and key hole cooperate with each other, which has good insertion and removal stability, reduces the risk of loosening due to heat or aging, and reduces the corresponding material and labor processing costs.
[0010] In summary, this utility model has the advantages of simple structure and good stability. Attached Figure Description

[0020] Example 1
[0021] In this embodiment, a quick-plug locking structure for energy storage connectors is proposed. It enables quick plugging and unplugging, has good stability, is simple in design, easy to manufacture and process, and is more convenient to install and use. It does not require any glue fixing measures and effectively eliminates the safety hazards caused by the locking structure loosening due to heat or aging. In addition, this structure also significantly improves the product manufacturing qualification rate and reduces material and labor costs.
[0022] like Figures 1-3 As shown in one embodiment of the present invention, the energy storage connector quick-plug locking structure includes a socket 1 and a plug 2. One end of the socket 1 is a locking end, and the outer side of the locking end is provided with a locking groove 101. The plug 2 is adapted to the socket 1 and is detachably connected to the socket 1. The plug 2 is provided with a button 4 mounting hole 202 and a key slot hole 201. A button 4 is installed in the button 4 mounting hole 202. The button 4 is provided with a spring mounting hole 401, and a spring is installed in the spring mounting hole 401. Spring 3, button 4 has a main body buckle 402 on one side and a key buckle 403 on the other side. The main body buckle 402 is adapted to the buckle groove 101 and the key buckle 403 is adapted to the key hole 201. The button 4 is installed in the button 4 mounting hole 202 by the spring 3. One end of the plug 2 is adapted to the buckle end and the plug 2 end is detachably connected to the buckle end. The main body buckle 402 is detachably connected to the buckle groove 101 and the key buckle 403 is detachably connected to the key hole 201.
[0023] The specific usage process of this utility model is as follows: one end of the plug 2 of this utility model is engaged and connected with the locking end of the socket 1. Under the action of the spring 3, the main body buckle 402 of the button 4 is engaged into the locking groove 101, and the plug 2 and the socket 1 are locked at this time. During the pressing process, the key buckle 403 engages with the key hole 201 and is just engaged in the key hole 201, which has a certain limiting effect on the button 4. Moreover, after the locking end of the socket 1 is coupled with the plug 2, the main body buckle 402 is just engaged with the locking groove 101. When the button 4 is pressed again, the spring 3 is compressed and the main body buckle 402 can leave the locking groove 101 to complete the separation of the plug 2 and the socket 1.
[0024] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
