Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1 to 6 This embodiment discloses a compensation structure for a DC connector, including a first connector 100 and a second connector 300. A first conductor 200 is fixed at the center of the first connector 100, and the first conductor 200 is connected to an external cable. A connecting cavity 310 is provided in the second connector 300, and a second conductor 400 is fixed in the connecting cavity 310. The second conductor 400 is connected to another external cable. The first connector 100 includes a connecting portion 110, and the first conductor 200 has a connecting groove 201. The connecting portion 110 is inserted into the connecting cavity 310, causing the second conductor 400 to be inserted into the connecting groove 201, thereby bringing the first conductor 200 and the second conductor 400 into contact and connecting the two cables.

[0024] The second connector 300 has a telescopic groove 320 communicating with the connecting cavity 310. The second conductor 400 passes through the telescopic groove 320. A second abutment 410, partially extending out of the telescopic groove 320 and movable along the second conductor 400, is provided within the telescopic groove 320. The second abutment 410 includes a first abutment portion 411 and a second abutment portion 412. The first abutment portion 411 is located inside the telescopic groove 320, and the second abutment portion 412 is located outside the telescopic groove 320. A spring 321 is provided within the telescopic groove 320. The spring 321 abuts against the first abutment portion 411 and pushes the second abutment 410 toward the opening of the connecting cavity 310. When the connecting part 110 is inserted into the connecting cavity 310, the second abutment portion 412 abuts against the end of the connecting part 110. Simultaneously, the connecting part 110 also pushes the second abutment 410 toward the side where the telescopic groove 320 is located, causing the end of the connecting part 110 to fit tightly against the second abutment portion 412. A locking member 500 is installed on the side wall of the connecting cavity 310. The locking member 500 can abut against the side of the connecting part 110, so that the end of the connecting part 110 is kept in close contact with the second abutment part 412, thereby ensuring a stable connection between the first connector 100 and the second connector 300.

[0025] The locking component 500 includes a support plate 530 fixed to the inner wall of the connecting cavity 310. A support groove 302 is provided on the side wall of the connecting cavity 310. One end of the support plate 530 is inserted into the support groove 302 to fix the support plate 530 to the side wall of the connecting cavity 310. The other end of the support plate 530 is provided with a first plate 510 extending toward the center of the connecting cavity 310. The first plate 510 is elastic, so that the first plate 510 tends to tilt toward the connecting portion 110. The first plate 510 is connected to the second plate 520, and the first plate 510 and the second plate 520 form a V-shaped structure. The connection between the first plate 510 and the second plate 520 forms a locking protrusion 540, which is embedded in the locking groove 124. The groove 124 is provided with a plurality of equally spaced abutment members 700, which contact the locking member 500. The abutment member 700 includes a fixing part 710 and an elastic part 720. The top of the fixing part 710 is provided with a fixing groove 711, and the elastic part 720 is provided with an insertion part 721 that is inserted into the fixing part 710 so that the elastic part 720 contacts the locking member 500. The elastic part 720 is made of rubber and has good elasticity. When the locking protrusion 540 is inserted between two adjacent abutment members 700, the elastic part 720 will deform, increasing the pressure on the locking protrusion 540, thereby increasing the friction between the locking protrusion 540 and the elastic part 720. This keeps the locking protrusion 540 in stable contact with the abutment member 700, further ensuring the stable connection between the first connector 100 and the second connector 300.

[0026] A compensation part 120 is sleeved on the outside of the connecting part 110. The compensation part 120 includes a first end 121 near the opening of the connecting cavity 310 and a second end 122 away from the opening of the connecting cavity 310. The compensation part 120 is provided with a first inclined surface 123, which gradually slopes towards the center of the first connector 100 from the first end 121 to the second end 122. A second inclined surface 301 that mates with the first inclined surface 123 is provided at the opening of the connecting cavity 310. When the connecting cavity 310 is inserted into the connecting cavity 310, the first inclined surface 123 and the second inclined surface 301 fit together. When the first inclined surface 123 and the second inclined surface 301 wear due to frequent insertion and removal, due to their inclined arrangement, they move further into the connecting cavity 310 through the connecting part 110, thereby compensating for the gaps caused by wear and ensuring a stable connection between the first connector 100 and the second connector 300.

[0027] In the compensation part 120, a first limiting groove 1211 is provided on the side where the first end 121 is located, and the first connector 100 is provided with a first limiting part 111 that is embedded in the first limiting groove 1211. A second limiting groove 1221 is provided on the side where the second end 122 is located. The connecting part 110 is provided with a limiting member 600 that covers the second limiting groove 1221 by means of a fastener 620. The limiting member 600 is provided with a second limiting part 610 that is embedded in the second limiting groove 1221, thereby restricting the movement of the connecting part 110 and ensuring the stable installation of the connecting part 110. At the same time, a guide surface 630 is provided on the outside of the limiting member 600. When the connecting part 110 is inserted into the connecting cavity 310, the guide surface 630 can guide the locking member 500 and prevent the locking member 500 and the limiting member 600 from blocking each other.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
