a waterproof cable

Abstract

The invention relates to the technical field of inhaul cables, in particular to a waterproof inhaul cable. The waterproof inhaul cable comprises an inhaul cable body and a waterproof joint connected to the periphery of the inhaul cable body. The inhaul cable body is wrapped with a plurality of stranded wires. As for the waterproof joint, an upper casing pipe is connected with an upper plug, an upper sealing block is arranged in the upper casing pipe and is in threaded connection with the inner wall of the upper casing pipe, the inner wall of a connection casing pipe is provided with a stop block extending in the axial direction, an upper sealing ring is arranged between the upper casing pipe and the connection casing pipe, a lower casing pipe is connected with a lower plug, a lower sealingring is arranged between the lower casing pipe and the connection casing pipe, a lower sealing block is arranged in the lower casing pipe and is in threaded connection with the lower casing pipe, anda plurality of spiral guide blocks are fixedly connected to the inner walls of the upper sealing block and the lower sealing block. The problem of poor waterproof performance of joints of existing inhaul cables is solved through clearance fit between the spiral guide blocks and every two adjacent stranded wires, the structure is simple, operation is convenient, the waterproof performance is better, the service life of the waterproof joint is prolonged, and the replacement cost and maintenance cost of the waterproof joint are reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof cable. Background technique [0002] Brake cable should be in the hand brake of the car, and it is an important connector for the car brake. The cable connector is the connector for connecting the brake cable. The existing cable connector has poor waterproof effect. Water seepage easily occurs in the gap between the adjacent two twisted wires covered, which leads to a reduction in the service life of the cable joint, and increases the manpower, material and financial costs of the cable joint replacement and maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem of poor waterproofness of the existing cable joints, the present invention provides a waterproof cable, at the connection between the upper casing and the connecting casing, and between the lower casing and the connection ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem of poor waterproofness of the existing cable joints, the present invention provides a waterproof cable, at the connection between the upper casing and the connecting casing, and between the lower casing and the connection The joints of the bushings are provided with an upper sealing ring and a lower sealing ring respectively. The spiral guide blocks evenly distributed on the inner walls of the upper sealing block and the lower sealing block block the gap between the two adjacent strands of water seepage, further waterproofing, and the structure Simple, easy to operate, better waterproof performance, improve the service life of the entire waterproof joint, and reduce the replacement and maintenance cost of the waterproof joint
