Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

Example 1

The waterproof cable shown in fig. 1-3 includes a cable body 100, the cable body 100 is connected to a motor 200, the cable body 100 includes a conductor body 110 and a waterproof case 120, wherein the conductor body 110 is disposed in the waterproof case 120, the exterior of the conductor body 110 is wrapped by an insulating case 111, a waterproof joint 300 is formed at the joint of the cable body 100 and the motor 200 by injection molding of waterproof insulating rubber, the conductor body 110 of the cable is connected to the motor 200 through a waterproof interface, the conductor body 110 in the waterproof joint 300 is disconnected, a conductor 301 is welded between the disconnected conductor bodies 110, the conductor 301 is covered by an insulating layer 311 for preventing contact between the conductor bodies 110 from short-circuiting, the specific conductor 301 is a copper rod 310, two ends of the copper rod 310 are respectively welded to the disconnected conductor bodies 110, so that when water flows to the position of the copper rod 310 along the conductor body 110, the water is blocked by the copper rod 310, and thus cannot flow into the motor 200.

As shown in fig. 1, a boss 320 is formed on the waterproof connector 300 through injection molding, a step hole 210 is formed at a connection position of the motor 200 and the cable body 100, the boss 320 of the waterproof connector 300 is clamped on a step of the step hole 210, a hollow screw 330 is sleeved on one side of the boss 320 of the waterproof connector 300, an internal thread 211 is formed at a large end of the step hole 210, the hollow screw 330 is meshed and fixed with the internal thread 211, the boss 320 is tightly pressed by the hollow screw 330, so that the boss 320 is tightly attached to the step hole 210, and water is prevented from entering the motor 200 through the step hole 210.

As shown in fig. 1, a rubber ring 331 is disposed between the hollow screw 330 and the boss 320, thereby further improving the waterproof effect.

As shown in fig. 4, the conductor body 110 in the waterproof connector 300 is wrapped by the insulating shell 111, so that after the conductor body 110 enters the motor 200, the insulating shell 111 is also wrapped to avoid short circuit.

As shown in fig. 5, a locking piece 220 is wrapped at a position of the cable body 100 close to the waterproof connector 300, the locking piece 220 is fixed on the motor 200 through a screw, and the locking piece 220 is adopted to prevent the water from entering the joint between the cable body 100 and the motor 200 due to the pulling of the cable body 100.
