Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a locking structure for an electrical connector includes a first locking device 1, a connector 2, and a second locking device 3. The first locking device 1 includes a locking cap 4, a shrinker 5, an anti-slip disc 7, and a waterproof cap 9. The locking cap 4 is threadedly connected to the shrinker 5. An anti-slip disc 7 is provided on the side of the shrinker 5 away from the locking cap 4, and patterns for increasing friction are provided on the surface of the anti-slip disc 7. A plurality of first gaps 18 are provided on the side of the shrinker 5 close to the locking cap 4. When the locking cap 4 is tightened, the shrinker 5 is compressed, resulting in the reduction of the first gaps 18. The shrinker 5 clamps the electrical connector to play a locking role. A water outlet 6 is provided on the side of the shrinker 5 close to the anti-slip disc 7. A sealing rail 8 is provided inside the shrinker 5, and the sealing rail 8 bonds the waterproof cap 9. The connector 2 is bolted to the second locking device 3. The connector 2 includes a connection housing 10 and a waterproof ring 11. The waterproof cap 9 is threadedly connected to the connection housing 10. A waterproof ring 11 is provided on the side of the connection housing 10 away from the first locking device 1. A fixed plate 12 is provided on the side of the connection housing 10 close to the second locking device 3, and a connection plate 13 is bonded to one side of the fixed plate 12. The second locking device 3 includes a base 14 and an upper seat 15. The top of the base 14 is bolted to the upper seat 15 through a locking bolt 16.

[0021] The working principle of the present utility model is as follows: When the electrical connector is inserted into the first locking device 1, hold the anti-slip disc 7 with one hand and tighten the locking cap 4 with the other hand. The locking cap 4 gradually compresses the shrinker 5 through the thread. The first gap 18 gradually becomes smaller under the action of the shrinker 5. The shrinker 5 compresses the electrical connector to achieve locking. At the same time, under the double waterproofing of the sealing rail 8 and the waterproof cap 9, it can effectively prevent water droplets from entering the interior of the connector 2 and avoid failures caused by water seepage. When the electrical connector is inserted into the second locking device 3, the second gap 17 between the base 14 and the upper seat 15 is gradually reduced by tightening the locking bolt 16, and the electrical connector is locked by the pressure of the base 14 and the upper seat 15. A pin can also be inserted into the pin hole 20 to achieve auxiliary locking. At the same time, under the double waterproofing of the waterproof jack 19 and the waterproof ring 11, it can effectively prevent water droplets from entering the interior of the connector 2 and avoid failures caused by water seepage. The locking mechanisms on both sides are simple and reliable, and can effectively ensure the structural strength during plug connection, achieving the purpose of reliable connection.
