Buried termite prevention cable distribution box

Abstract

The invention discloses a buried termite prevention cable distribution box, which comprises a shell, a stress supporting frame, a waterproof sleeve, cable connectors and insulating fireproof filling pieces, wherein the waterproof sleeve is arranged on the stress supporting frame in a sleeved mode, the cable connectors and the insulating fireproof filling pieces are installed in the shell, the stress supporting frame is partially arranged in the shell, and gaps between the stress supporting frame and the shell are filled with the insulating fireproof filling pieces; and the cable connectors are arranged in the stress supporting frame, and two ends of each cable connector are processed to be U-shaped ports. The buried termite prevention cable distribution box further comprises a termite protection sleeve, wherein the termite protection sleeve is arranged on the shell in a sleeved mode, and the termite protection sleeve is at least composed of a high-density polyethylene inner protection layer, an intermediate nylon protection layer and a high-density polyethylene outer protection layer. The three hard composite material protection layers of the termite protection layer on the distribution box significantly increase the termite damage prevention ability, greatly improve the ability of preventing biting of termites, and can enable the distribution box to acquire good termite prevention effects under environmental friendly and drug-contamination-free conditions.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an underground termite-proof cable distribution box. Background technique [0002] Cable distribution box (Cable Distribution Box) is a kind of equipment used for branching, branching, splicing and switching circuits of cable lines, especially when connecting high-voltage cables, it is more commonly used, and most of them are used outdoors. Cable distribution boxes are divided into two categories according to their electrical composition: one type does not contain any switchgear, and there are only accessories for processing and connecting cable ends in the box. The structure is relatively simple, the volume is small, and the function is relatively single. , which can be called ordinary distribution box; the other type is that there are not only accessories of ordinary distribution box in the box, but also one or more switchgears. Large, high cost, can be called advan...

AI Technical Summary

Problems solved by technology

Cable distribution boxes are divided into two categories according to their electrical composition: one type does not contain any switchgear, and there are only accessories for processing and connecting cable ends in the box. The structure is relatively simple, the volume is small, and the function is relatively single. , which can be called ordinary distribution box; the other type is that there are not only accessories of ordinary distribution box in the box, but also one or more switchgears. Large, high cost, can be called advanced distribution box

The cable distribution box of the prior art usually has a complex structure, and it is installed outdoors, so it is easy to not only occupy space, but also easy to pull out the cable, or cause electric leakage, causing certain potential safety hazards
