Problems solved by technology

There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. The distance between adjacent low-voltage switches is small, and the space of the low-voltage equipment itself is relatively small, so that the above two grounding wires cannot be directly grounded in the low-voltage distribution box. The disadvantage is that it will expand the scope of power outages, and it is also prone to safety failures such as grounding short circuits.

Embodiment 1

[0064] Such as Figure 1-6 As shown, a cable grounding transition device for an electrical distribution box includes a wire connecting part 1 and a grounding connecting part 2, the wire connecting part 1 is connected to the grounding connecting part 2, and the wire connecting part 1 is provided with a The clamping space 101 and the locking device 102 holding the cable grounding bare wire 601, the size of the clamping space 101 is adjusted through the locking device 102, so that the wire connecting part 1 will pass through the clamping space 101 The cable grounding bare wire 601 Clamping: the grounding connection part 2 is provided with a surface that facilitates the installation of the grounding wire, and the surface of the cable clamping space 101 that clamps the bare grounding wire 601 of the cable and the grounding connection part 2 is electrically conductive.

[0065] The cable grounding transition device for the electrical distribution box also includes a protective shell...

Embodiment 2

[0074] On the basis of the technical solution of Embodiment 1 of a cable grounding adapter device for an electrical distribution box of the present invention, the following improvements are made:

[0075] Such as figure 2 As shown, the ground connection part 2 and the wire connection part 1 are independent structures that are movably connected. There is an external thread 2011 matched with the distance adjustment screw hole 1021, one end of the ground connection part 2 enters the cavity 103 through the distance adjustment screw hole 1021 and the inner wall of the cavity 103 opposite to it constitutes the clamping space 101, by rotating the The ground connection part 2 can adjust the size of the wire clamping space 101 , so that the wire connection part 1 locks the cable ground bare wire 601 passing therethrough.

Embodiment 3

[0077] On the basis of the technical solution of Embodiment 1 of a cable grounding adapter device for an electrical distribution box of the present invention, the following improvements are made:

[0078] Such as Figure 1-4 As shown, the wire connection part 1 includes a first body 104 and a second body 105, and the first body 104 and the second body 105 are respectively provided with a first clamping part 1041 and a second clamping part 1051. The wire part 1041 and the second wire clamping part 1051 form the wire clamping space 101, one side of the first body 104 and the second body 105 is hinged, and the other side is movably connected by a locking bolt 1025, through which the locking bolt 1025 The connection can adjust the size of the clamping space 101 , so that the first body 104 and the second body 105 can lock the cable ground bare wire 601 passing therethrough.

[0079] The first clamping portion 1041 and the second clamping portion 1051 are grooves disposed on the f...

The cable grounding connection device comprises a lead wire connection part, a grounding connection part and a corresponding protective shell, wherein the grounding connection part is connected with the lead wire connection part; a wire clamping space for clamping a cable grounding bare wire is arranged on the lead wire connection part; the surface for facilitating installation of a grounding wire is arranged on the grounding connection part; and the surface, for clamping the cable grounding bare wire, in the wire clamping space and the grounding connection part have conductivity; the lead wire connection part is used for clamping the cable grounding bare wire through the wire clamping space when used; and the grounding connection part is connected with the grounding wire, so that connection of a cable and the grounding wire is achieved; the cable grounding connection device is simple in structure, easy to process, simple and convenient to install and dismantle, good in safety and high in universality; and the grounding efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular to a cable grounding transfer device for an electric distribution box. Background technique [0002] In the process of overhauling and maintaining power equipment or cable lines, it is necessary to ensure that the power equipment or cable lines are reliably grounded to prevent the danger to the human body caused by the dangerous voltage generated by a sudden call or the induced voltage generated by adjacent lines. Therefore, it is a very important electrical safety measure to ground the electrical equipment or cable lines through the grounding wire. There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. The distance between adjacent low-voltage switches is small, and the space of the low-voltage equipment itself is relatively small, so the above two grounding wires cannot be directly grounded in the low-...
