[0027] In one embodiment of the waterproof power cable structure of this utility model, please refer to... Figures 1 to 6The waterproof power cable structure includes a cable 100 and an electrical connector 200, with the connector 200 connected to one end of the cable 100. The electrical connector 200 includes a housing 210, an insulating sleeve 220, a connecting terminal 230, a waterproof ring 240, and a sealing ring 250. One end of the housing 210 has a plug end 211 with a mating surface 212. The mating surface 212 has a groove 213 along its edge, and the sealing ring 250 is housed within the groove 213. The mating surface 212 also has a through hole 214 for a locking screw to pass through and connect with other corresponding connectors. A connecting portion 215 extends from the back side of the mating surface 212, and the connecting portion 215 has two independent mounting holes 216 that penetrate both ends of the housing 210. Each through hole 214 is provided with an insulating sleeve 220. One end of the insulating sleeve 220 is located in the mounting hole 216, and the other end extends from the mating surface 212. Each insulating sleeve 220 is provided with a connecting terminal 230. One end of the connecting terminal 230 near the connecting part 215 is provided with a connecting hole 231, and the other end is provided with a plug hole 232. A pin 260 is provided in the plug hole 232. A cable 100 is inserted into each mounting hole 216. The conductor of the cable 100 is inserted into the connecting hole 231. A waterproof ring 240 is fitted on the cable 100, and the waterproof ring 240 seals the mounting hole 216. In this embodiment, the waterproof power cable seals the gap between the cable 100 and the mounting hole 216 through the sealing ring 250. When the connector 200 is plugged into other connectors, the waterproof ring 240 is fitted and sealed with the end face of the other connector. Therefore, it can isolate the connecting terminals inside the shell, prevent water and dust from entering, and provide good protection for the connecting terminals, thus achieving the effect of waterproof and dustproof cable.

[0028] Furthermore, refer to Figure 6 The insertion hole 232 has a screw hole, and one end of the pin 260 has an external thread, which is connected to the screw hole.

[0029] Furthermore, refer to Figure 5 and Figure 6 The insertion hole 232 is also equipped with a conductive copper sleeve 270. The conductive sleeve 270 can increase the stability of conductivity and wear resistance.

[0030] Furthermore, refer to Figure 5 and Figure 6 The conductive copper sleeve 270 is provided with multiple clearance grooves 271, and an elastic arm 272 is formed between two adjacent clearance grooves 271. The elastic arm 272 bends inward. When inserted into the conductive copper sleeve 270, the elastic force of the elastic arm 272 is used to elastically connect the electrical terminal of another connector, increasing the tightness of the connection.

[0031] Furthermore, the clearance groove 271 is inclined along the axial direction.

[0032] Furthermore, refer to Figures 1 to 4The insulating sleeve 220 is also provided with an elastic buckle 221, and the end of the connecting terminal 230 with the insertion hole 232 is provided with a slot 233, and the elastic buckle 221 engages with the slot 233.

[0033] Furthermore, the waterproof ring 240 includes a back cover 241 and a rubber sleeve 242. The rubber sleeve 242 is disposed inside the back cover 241 and is fitted onto the cable 100. The back cover 241 is snapped into the outer shell 210. This provides a limiting and fixing function for the rubber sleeve 242, ensuring that the rubber sleeve 242 remains within the mounting hole 216 and provides a sealing function.

[0034] Furthermore, refer to Figure 4 and Figure 7 The cable 100 is also fitted with a support sleeve 300, which is located inside the mounting hole 216. The support sleeve 300 supports the cable 100 and prevents it from moving within the mounting hole 216.

[0035] Furthermore, refer to Figure 7 The support sleeve 300 is further fitted with an elastic support sleeve 310, which is supported within the mounting hole 216. The elasticity of the elastic support sleeve 310 provides elastic support for the cable, thereby cushioning the cable 100.

[0036] Furthermore, the elastic support sleeve 310 is provided with a plurality of elastic support arms 311, which are supported on the inner sidewall of the mounting hole 216.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
