Problems solved by technology

However, when the cable terminal is connected to the bottom of the transformer, the terminal is located below, and the slope setting of the rain skirt can easily cause rainwater to flow into the joint between the sealing tube and the cold-shrinkable outdoor terminal bushing.

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] A cold-shrinkable cable terminal, refer to figure 1 , including three sets of cold-shrinkable sleeves 1 and three sets of insulating tubes 2, cold-shrinkable sleeves 3, cold-shrinkable sealing tubes 4 and terminal blocks 5. One end of the insulating tube 2 is fixed on the cold-shrink sleeve 1, the other end is connected to the cold-shrink sleeve 3, and the other end of the cold-shrink sleeve 3 is fixed to the terminal 5 through the cold-shrink sealing tube 4 to realize the installation and setting of the wire .

[0035] refer to figure 2 , the cold shrinkable sleeve 3 includes a stress taper 6 at one end and a sealing sleeve 7 at one end, and a gel band 22 is arranged on the inner surface of the sealing sleeve 7, so that the sealing sleeve 7 can be quickly fixed with the wire when the sealing sleeve 7 is installed, while ensuring Good sealing. A p...

Abstract

The invention discloses a cold-shrinkage type cable terminal, and the terminal sequentially comprises a cold-shrinkage three-branch sleeve, an insulating tube, a cold-shrinkage sleeve, a cold-shrinkage sealing tube and a wiring terminal from bottom to top. The cold-shrinkage sleeve comprises a stress cone part, a sealing sleeve and a rain skirt arranged on the sealing sleeve. The rain skirt comprises an obliquely arranged skirt edge and a mounting ring with a supporting tube strip. Compared with the prior art, the rain skirt and the sealing sleeve are arranged in a split manner, so that the installation direction and the installation number of the rain skirts can be adaptively installed according to the actual use condition of the cable terminal, and the cable terminal is more stably and safely installed.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a cold-shrinkable cable terminal. Background technique [0002] The cold-shrinkable cable terminal head is made of elastomer material, injected and vulcanized in the factory, and then expanded in diameter, lined with plastic spiral supports to form various cable accessories. When installing on site, put these pre-expansion parts on the treated cable ends or joints, pull out the inner supporting plastic spiral strip (support), and press it on the cable insulation to form a cable accessory. Because it relies on elastic retraction force at room temperature, instead of shrinking with fire like heat-shrinkable cable accessories. [0003] The Chinese patent "Cold-shrinkable Cable Outdoor Terminal" with the notification number CN104269808A includes terminal blocks, sealing tubes, and cold-shrinkable outdoor terminal sleeves. By installing the above-mentioned accessories...
