Cable bundle water blocking structure and mounting method thereof

Abstract

The invention provides a cable bundle water blocking structure and a mounting method thereof, and relates to the field of waterproof cables. The cable bundle water blocking structure comprises cables,an isolation block and a coating pipe; cable cores of cable bundles connected with a threading hole are exposed; the isolation block is coupled with the exposed cable core of each cable so as to fillthe gaps among the plurality of cables and truncation surfaces appear in the axial direction of the cable bundles; and the coating pipe is extruded between the isolation block and the inner wall of the threading hole and is sleeved outside the isolation block. According to the cable bundle water blocking structure and the mounting method thereof, water is prevented from entering into mounting holes from gaps between axial cable cores of the cable bundles and the water blocking effect is relatively remarkable.

Description

technical field [0001] The invention relates to the field of waterproof cables, in particular to a cable bundle water-blocking structure and an installation method. Background technique [0002] Cables are widely used in power and communication transmission. With the continuous development of technology, the occasions where cables are applicable become more complicated and diversified. In the prior art, the waterproofing of the cable only focuses on the sheath part, so that the sheath can achieve a waterproof effect. In the process of realizing the present invention, the applicant found that even if the outer skin is not damaged, the electric wire still has water ingress, especially for electric wires containing multiple core wires, the water ingress is more obvious. There is a gap between the core wire and the sheath, and the shrinkage caused by air causes water to enter from the core of the wire interface, causing water to enter the inside of the wire. Once water enters t...

In the process of realizing the present invention, the applicant found that even if the outer skin is not damaged, the electric wire still has water ingress, especially for electric wires containing multiple core wires, the water ingress is more obvious. There is a gap between the core wire and the sheath, and the shrinkage caused by air causes water to enter from the core of the wire interface, causing water to enter the inside of the wire. Once water enters the device, it will damage or even burn the device
