DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-4 In this embodiment, the high-current power cable of the energy storage battery includes a first shell 100, a wire connector 105 is fixedly installed inside the first shell 100, and the wire connector 105 is connected to the inside of the first shell 100 by glue material. The wire connector 105 is inserted and connected to the inside of the docking slot 104, and the docking slot 104 is opened inside the docking head 102. One end of the wire connector 105 is installed with a current wire 101, and the docking head 102 is connected and fixed to the upper end of the first shell 100 by a docking fixing component 200. The docking fixing component 200 includes a fixed Fixed block 201, the lower end of the fixed block 201 is installed on the upper end of the docking head 102, and a through-hole 209 and a clamping groove 202 are provided inside the fixed block 201. The clamping groove 202 is clamped with a clamping block 203, and the clamping block 203 is upside down inside the clamping groove 202 to ensure that the clamping block 203 cannot move in the clamping groove. The clamping block 203 is fixedly installed on the upper end of the clamping plate 205, and the clamping plate 205 can move in the through-hole 209. A friction pad 206 is fixedly installed on the upper end of the clamping plate 205. The friction pad 206 is a rubber pad with a textured surface, and the friction pad 206 can have an anti-slip effect.

[0022] like Figure 3 、 Figure 4-5As shown, a telescopic rod 212 is fixedly installed at the lower end of the card plate 205, and the telescopic rod 212 passes through the interior of the fixed ring plate 207, and the fixed ring plate 207 is connected to the upper end of the first shell 100 by screws. A through hole is opened inside the first shell 100, and the telescopic sleeve 208 is connected and fixed by screws inside the through hole of the first shell 100. A compression spring 214 is installed inside the telescopic sleeve 208, and the upper end of the compression spring 214 is connected to the lower end of the moving block 213 by bolts. The moving block 213 moves inside the telescopic sleeve 208, and the upper end of the moving block 213 is installed with a telescopic rod 212. In actual use, when the staff inserts the wire connector 105 into the docking slot 104 of the docking connector 102, the card plate 205 will be further moved to the through hole 209. When the card plate 205 is in the through hole 20 During the movement, the clamping block 203 is squeezed with the inside of the clamping slot 202 of the fixed block 201, and the clamping plate 205 is further compressed and moved downward by the telescopic rod 212, and the moving block 213 is further moved downward inside the telescopic sleeve 208, and then the compression spring 214 is compressed. When the clamping block 203 moves to the position of the clamping slot 202, the clamping block 203 is no longer squeezed, and the compression spring 214 rebounds, driving the moving block 213 and the telescopic rod 212 to move upward, further driving the clamping plate 205 to move upward, and finally the clamping block 203 is penetrated and clamped in the clamping slot 202 of the fixed block 201, which can prevent the wire connector from gradually loosening due to vibration generated when the equipment is running, and prevent the loose wire connector from causing unstable current transmission of the energy storage battery, affecting the normal operation of the energy storage battery system.

[0023] By means of the docking fixing assembly 200, an automatic locking mechanism is realized through the combination of the telescopic rod 212 and the compression spring 214, so that the wire connector 105 can be firmly fixed in the docking slot 104 after insertion, reducing the problem of loose wire connectors caused by vibration during equipment operation. A stable connection helps to maintain continuous and stable transmission of current, which is crucial for the normal operation of the energy storage battery system, avoiding current instability that may cause system performance degradation or failure, thereby improving the reliability and durability of the entire energy storage battery system.

[0024] like Figure 2 、 Figure 4-5 As shown, threaded holes 211 are provided inside both sides of the fixed block 201, and the inside of the threaded hole 211 is connected with a moving rod 204 by tightening and rotating. The moving rod 204 passes through the inside of the through-hole 209, and fixed plates 103 are installed on both side ends of the docking joint 102. In actual use, by manually twisting the moving rod 204 and rotating the moving rod 204 in the threaded hole 211, the moving rod 204 is moved through the through-hole 209, which can prevent the block 203 and the card plate 205 from moving downward.
