Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] see Figure 1-3 , the present invention provides a technical solution:

[0016] A pre-expanded cold shrink cable terminal, comprising a cold shrink sleeve 1 and a terminal 2, the cold shrink sleeve 1 includes a first insulating rubber layer 11, a foam layer 12 and a second insulating rubber layer 13, the foam layer 12 is located between the first insulating rubber layer 11 and the second insulating rubber layer 13. The inner wall of the cold shrinkable...

Abstract

The invention discloses a pre-dilated cold shrinkage cable terminal. The pre-dilated cold shrinkage cable terminal comprises a cold shrinkage casing tube and a wiring terminal, wherein the inner wall of the cold shrinkage casing tube is provided with a supporting tube; the supporting tube is internally provided with a shrinkage core rope; a supporting core rope is arranged below the supporting tube, and the supporting core rope is positioned inside the cold shrinkage casing tube; supporting pieces are arranged at two ends of the supporting tube respectively; a shrinkage port and a connecting port are formed in two ends of the cold shrinkage casing tube respectively; stress cones are arranged at two ends of the supporting piece with the shrinkage port respectively; a casing tube is sleeved on the exterior of the connecting port; and the end, away from the cold shrinkage casing tube, of the sleeve is connected with the wiring terminal. The pre-dilated cold shrinkage cable terminal solves the disadvantage that the shrinkage core rope is unlikely to draw out or is easy to be broken caused by the fact that the cable is sealed through the connecting port when a common cable terminal is installed and the problems that the sealing performance is reduced and the performance of the cable terminal is influenced caused by the facts that gaps are easily generated by different installation process conditions.

Description

technical field [0001] The invention relates to the technical field of cable terminals, in particular to a pre-expanded cold-shrinkable cable terminal. Background technique [0002] The existing cold-shrinkable cable terminal has a split structure, and special tools are used to expand the inner diameter of the cable terminal sleeve and the stress tube. The general cable terminal seals the cable through the connection port during installation, and the shrinkage core rope is not easy to pull out or easy to break, and the installation process conditions are different, which is easy to produce gaps, resulting in a decrease in sealing performance and affecting the performance of the cable terminal. Contents of the invention [0003] The purpose of the present invention is to provide a pre-expanded cold-shrinkable cable terminal to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the fol...
