DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A cable for a charging pile includes a cable body 1, a positioning mechanism 2 and an auxiliary positioning mechanism 4, wherein the cable body 1 is connected to a charging pile body 3.

[0025] The positioning mechanism 2 includes a disc 201 that is interference fit with the cable body 1. Specifically, the disc 201 has a through hole that cooperates with the cable body 1, and a pair of plug blocks 2010 are provided on the disc 201. A pair of protruding rods 202 are provided on the disc 201. The protruding rods 202 are provided with assembly grooves 2020, and the protruding rods 202 are provided with movable grooves 2021 connected to the assembly grooves 2020. A spring 203 is provided in the assembly groove 2020, and a positioning rod 204 is fixedly connected to the spring 203. A shift block 205 is provided at the bottom of the positioning rod 204, and the shift block 205 passes through the movable groove 2021.

[0026] Furthermore, the shape of the shift block 205 is T-shaped, and the shift block 205 is slidably matched with the movable groove 2021 .

[0027] The auxiliary positioning mechanism 4 is arranged at the bottom of the charging pile body 3 . The auxiliary positioning mechanism 4 has a pair of fixing blocks 402 . The fixing blocks 402 are provided with positioning grooves 4020 . The positioning grooves 4020 cooperate with the positioning rods 204 .

[0028] When in use, first move the two shift blocks 205 so that the shift blocks 205 slide to drive the positioning rod 204 to move in the assembly groove 2020 and squeeze the spring 203, and then clamp the disc 201 in the hollow column 401. At this time, release the shift block 205, and under the reset of the spring 203, the positioning rod 204 extends from the assembly groove 2020 and extends into the positioning groove 4020, which can provide additional resistance when the cable body 1 is accidentally pulled, effectively preventing the cable body 1 from being over-stretched, thereby maintaining the stability of the connection end between the cable body 1 and the charging pile body 3, which can not only improve the reliability of charging, but also reduce the charging interruption phenomenon caused by the looseness of the cable body 1.

[0029] The auxiliary positioning mechanism 4 also includes a hollow column 401, which is arranged at the bottom of the charging pile body 3. A pair of notches 4010 are opened on the hollow column 401, and the pair of notches 4010 cooperate with the protruding rod 202. A pair of slots 4011 are opened on the hollow column 401, and the slots 4011 cooperate with the plug block 2010.

[0030] Furthermore, a pair of slots 4011 are formed on the hollow column 401 , and the slots 4011 cooperate with the insert block 2010 .

[0031] Furthermore, the inner diameter of the hollow column 401 is the same as the outer diameter of the disc 201 , so that the disc 201 can be snapped into the hollow column 401 .

[0032] Specifically, after the disc 201 is inserted into the hollow column 401, the protruding rod 202 is engaged in the notch 4010, and the insert block 2010 is engaged in the slot 4011, so that the protruding rod 202 is aligned with the fixed block 402, and then it can play an auxiliary guiding role in the connection and positioning of the positioning rod 204 and the fixed block 402, thereby reducing the time and labor costs in the positioning process and improving the positioning efficiency.
