DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] The utility model provides a waterproof sealed vehicle-mounted cable as Figures 1-5 As shown in a kind of waterproof sealed vehicle-mounted cable, including first cable body 1 and second cable body 2, first cable body 1 and second cable body 2 between being provided with connecting portion 13, connecting portion 13 can be connected by the way of setting connector plug-in or manual winding, can be adjusted according to specific use condition.

[0023] To realize the protection of connecting portion 13, first positioning plate 3 is fixedly connected to the end of first cable body 1 close to second cable body 2, second positioning plate 4 is slidably arranged on second cable body 2, and connecting portion 13 is located between first positioning plate 3 and second positioning plate 4. The side of first positioning plate 3 facing second positioning plate 4 is fixedly connected with a round sleeve 5, the side of second positioning plate 4 facing first positioning plate 3 is fixedly connected with a ring box 6, and the end of ring box 6 away from second positioning plate 4 is slidably provided with a sliding sleeve 7, and sliding sleeve 7 is plugged with round sleeve 5.

[0024] Positioning assembly is arranged between first positioning plate 3 and second positioning plate 4, and the positioning assembly comprises a circular block 10, a clamping tooth 14, a through slot 15, a square plate 16, a clamping hook 17 and a torsional spring 18. The side of square plate 16 away from second positioning plate 4 is fixedly connected to first positioning plate 3, and the through slot 15 is formed in first positioning plate 3, and the through slot 15 is correspondingly distributed with square plate 16. The clamping hook 17 is rotatably arranged on square plate 16, the clamping tooth 14 is fixedly connected to second positioning plate 4, and the clamping tooth 14 passes through the through slot 15, the circular block 10 is fixedly connected to square plate 16, the torsional spring 18 is sleeved on the circular block 10, one end of clamping hook 17 is matched with torsional spring 18, and the other end of clamping hook 17 is matched with clamping tooth 14.

[0025] Specifically, after the core of first cable body 1 and second cable body 2 is connected, the second positioning plate 4 is slid on the second cable body 2, so that the second positioning plate 4 drives the ring box 6 and the sliding sleeve 7 to move towards the first positioning plate 3, the sliding sleeve 7 is plugged on the round sleeve 5, and the sliding sleeve 7 is abutted on the first positioning plate 3, the sliding sleeve 7 is contracted towards the inside of the ring box 6, and the ring box 6 and the sliding sleeve 7 form a protection structure to protect the connecting portion 13.

[0026] In the process, the tooth 14 passes through the slot 15, when the tooth 14 abuts on the outer arc surface of the hook 17, the hook 17 will be swung, the end of the hook 17 away from the tooth 14 extrudes the torsion spring 18 to contract, with the continuous movement of the tooth 14, the reset spring force of the torsion spring 18 makes the hook 17 reset, the tooth 14 and the hook 17 are connected, the first cable body 1 and the second cable body 2 are connected and fixed, the operation is convenient, and the use efficiency of the vehicle-mounted cable connection is improved.

[0027] In order to realize the waterproof effect, the inner ring of the ring box 6 is fixedly connected with the air bag 11, and the air bag 11 is attached to the second cable body 2. The ring box 6 is provided with a gas passage 12, and the ring box 6 communicates with the air bag 11 through the gas passage 12.

[0028] Specifically, the second positioning plate 4 drives the ring box 6 and the sliding sleeve 7 to move towards the first positioning plate 3, so that the sliding sleeve 7 is inserted into the circular sleeve 5 and abuts on the first positioning plate 3. The sliding sleeve 7 is retracted into the ring box 6, so that the gas in the ring box 6 enters the air bag 11 through the gas passage 12. The air bag 11 expands and abuts on the outer wall of the second cable body 2, achieving the effect of sealing and waterproofing. At the same time, the fixing between the second positioning plate 4 and the second cable body 2 is completed, avoiding the separation of the connecting part 13 caused by tearing, and improving the stability of the vehicle-mounted cable.

[0029] In order to facilitate the reset of the sliding sleeve 7, an elastic assembly is arranged in the ring box 6. The elastic assembly includes a first magnet 8 and a second magnet 9. The first magnet 8 is fixedly connected to the sliding sleeve 7, and the second magnet 9 is fixedly connected to the inner wall of the ring box 6. The first magnet 8 and the second magnet 9 repel each other. When the sliding sleeve 7 is retracted into the ring box 6, the repulsive force between the first magnet 8 and the second magnet 9 needs to be overcome, so that the sliding sleeve 7 always abuts on the first positioning plate 3. When the first positioning plate 3 and the second positioning plate 4 are separated, the repulsive force between the first magnet 8 and the second magnet 9 makes the sliding sleeve 7 reset, and the air bag 11 shrinks.
