Base of combined electrical box body

Abstract

The invention discloses a base of a combined electrical box body, which comprises four identical side connecting plates (1) and is characterized in that each side connecting plate (1) comprises a main panel (1.1) and a head side flange (1.2), the head side flange (1.2) is provided with limiting raised bars (2), the head side flange (1.2) is provided with a first screw slot (3), and the reverse side of the main panel (1.1) is provided with limiting insertion slots (4) and a threaded hole (6); the four side connecting plates (1) are connected end to end to form a closed frame, the limiting raised bars (2) at the head end of each side connecting plate (1) are inserted into the limiting insertion slots (4) at the tail side of the last side connecting plate (1), and the head end of each side connecting plate (1) is fixed with the tail side of the last side connecting plate (1) through a screw which penetrates through the first screw slot (3) of the side connecting plate (1) and screwed into the threaded hole (6) of the last side connecting plate (1). The base disclosed by the invention is simple in structure, convenient to in assembly, low in mold opening cost and good in strength.

Description

technical field [0001] The invention relates to a base of an electrical box, in particular to a base of a combined cable branch box or a power branch box. Background technique [0002] The base of the electrical box in the prior art is generally a glass fiber reinforced plastic structure that is assembled in two halves or integrally molded, or a plastic structure that is integrally injection molded. Regardless of whether it is a two-half type or a monolithic type, there are complex shapes and structures, and it is difficult to open the mold. A series of problems such as high cost, high molding scrap rate, and low yield rate. Moreover, once a part of the integral type is damaged, the whole is completely scrapped. In the prior art, there are also split bases, but the strength requirements for the connectors of each part of the split base are very high, and sheet metal connectors must be used, such as right-angled two-way sheet metal connectors or three-way connectors in XYZ d...

Problems solved by technology

[0002] The base of the electrical box in the prior art is generally a glass fiber reinforced plastic structure or an integral injection molded plastic structure that is split in two halves or integrally molded. Regardless of whether it is a two-half type or an integral type, there are complex shapes and structures. A series of problems such as high cost, high molding scrap rate, and low yield

Moreover, once a part of the integral type is damaged, the whole is completely scrapped.

In the prior art, there are also split bases, but the strength requirements of the connectors of each part of the split base are very high, and sheet metal connectors must be used, such as right-angled two-way sheet metal connectors or three-way XYZ three-way connectors. Connect the various parts into an integral base through sheet metal parts, which will inevitably increase the overall cost of the base, and the installation process of the sheet metal connectors is very cumbersome, time-consuming and laborious; moreover, the split base is also composed of parts with different structures , each part still needs to open a set of molds separately, and the cost of mold opening is still high
