Description

Equipotential terminal connection box

technical field

The utility model relates to the field of safe power utilization of energy, electric power and communication systems, in particular to an equipotential terminal connection box.

Background technique

The equipotential terminal connection box is a low-voltage power distribution system suitable for various buildings and equipment. The equipotential connection made to prevent explosions and fires caused by indirect contact and grounding system failures can effectively prevent building lightning protection system failures. Interference with damage accidents caused by overvoltage of electronic information equipment. Ordinary equipotential terminal connection box covers are usually hinged and locked to control closing and opening, or are directly fixed to the box body with bolts, which will cause some inconvenience in installation or maintenance. At the same time, there are wire inlet and outlet holes on the box body, and the cables enter the box body through the wire inlet and outlet holes and are connected to the bus bar. This will easily lead to crowded space inside the box body, irregular cable connections, and inconvenient installation or maintenance.

Utility model content

The utility model aims to provide a comprehensive equipotential terminal connection box, which can realize its safety function, enhance the practicality and applicability, increase the operable space, more standardize the internal cable arrangement, and facilitate installation and maintenance .

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

The equipotential terminal connection box disclosed by the utility model includes a box cover, a box body, a grounding copper bar, a bus bar, and at least one equipotential connector, and is characterized in that: the bus bar is fixed in the box, and the grounding copper bar 1. One end of the equipotential connector is connected to the bus bar, the other end of the grounding copper bar and the equipotential connector is located outside the box through the side wall of the box, and the box cover and the box are connected by thumb screws.

Further, the outer bottom surface of the box is provided with fixing buckles, and the number of the fixing buckles is not less than the number of equipotential connectors.

Preferably, the grounding copper bar and the equipotential connector respectively pass through opposite side walls of the box body.

Further, an installation space or a fixing post for installing an equipotential connector is reserved in the box.

The utility model has the following beneficial effects:

1. Compared with the ordinary equipotential terminal connection box (box), it uses hand-tight screws to fix or open the box cover, which is easier to operate and saves the troublesome process of having to use tools to fix it during the installation process. When the internal equipotential connector When it is damaged and needs to be replaced, the cover can be opened and replaced without other tools, which is convenient and simple.

2. The case is no longer designed with holes for incoming and outgoing wires, but one end of the equipotential connector is connected to the cable through the bottom plate or side wall of the box. The outer wall of the box is near the equipotential connector. Fastening buckle, during the construction on site, the cable can be fixed directly with the cable tie, which is simple and convenient.

3. It can meet the requirements of all conventional equipotential connection terminals and has comprehensive functions. All equipotential connectors are equipped with mounting holes or fixing posts. Compared with ordinary equipotential junction boxes, it has stronger practicability and applicability, larger operating space, and more standardized internal cable connections.
