Problems solved by technology

However, in this method, most of the materials used are not elastic, and the combination of the material and the electrical building skin is not tight enough and there are gaps. Therefore, there are also problems such as damp, water, and damage to the cable, and the electrical building is wrapped. Together, when the cable sheath is damaged, it may cause mutual water seepage and interference between the cables.

Embodiment Construction

[0018] The present invention will be further explained below in conjunction with the accompanying drawings.

[0019] A cable port protection device, comprising a sleeve body, the sleeve body includes a front section 1, a middle section 2 and an end section 3 whose diameters are successively reduced, the lower end of the front section 1 is open, and the upper end of the end section 3 is closed .

[0020] In the above cable port protection device, the front section 1, the middle section 2 and the end section 3 are all tapered with a taper of 4-10°. The diameter ratio at the largest ends of the front section 1 , middle section 2 and end section 3 is 2.2-2.5:1.5:1. In this embodiment, the taper is selected as 8°, the diameters at the largest ends of the front section 1, the middle section 2 and the end section 3 are respectively 80mm, 54mm, and 36mm, and the length of each section is 100mm.

[0021] In the above cable port protection device, the lower end of the front section 1 ...

Abstract

The invention relates to a cable installation technology, in particular to a cable port protection device which comprises a sleeve body. The sleeve body comprises a front section, a middle section and a tail section, the diameters of the front section, the middle section and the tail section are sequentially reduced, the lower end of the front section is open, and the upper end of the tail section is closed. The structure can realize tight connection and is suitable for cables with different diameters.

Description

technical field [0001] The invention relates to cable installation technology, in particular to a cable port protection device. Background technique [0002] A cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering. Erection in the air or installed in the ground, underwater, etc., for telecommunications, power transmission. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints, and the cable joints in the middle of the cable line are called intermediate joints. [0003] In engineering construction, due to the influence of the project site environment, the cable is likely to suffer from lake humidity, rain, snow, flooding, etc., and may also be damaged by external forces, which may cause t...
