no. 1 example

[0042] The first embodiment: as Figure 6 As shown, the movable clamping part is a J-shaped plate, and the J-shaped plate is placed horizontally, wherein the horizontal part 161 of the J-shaped plate is fixed to the busbar to be hung, and the curved part 162 of the J-shaped plate is the limit part.

no. 2 example

[0043] The second embodiment: as Figure 7 As shown, the movable clamping part is an L-shaped plate, and the L-shaped plate is placed horizontally, wherein the horizontal part 163 of the L-shaped plate is fixed to the busbar to be hung, and the vertical part 164 of the L-shaped plate is the The limit part described above.

[0044] The upper surface of the horizontal part of the J-shaped plate or the horizontal part of the L-shaped plate is provided with a sawtooth profile 19, and the busbar is fixed on the top of the fixed line clamp body with the horizontal part of the J-shaped plate or the horizontal part of the L-shaped plate. There are also serrated teeth on the surface.

no. 3 example

[0045] The third embodiment: as Figure 8 As shown, the upper side of the fixed wire clamp body close to its opening is provided with a downwardly extending limiting block 20, and the described limiting block cooperates with the described limiting part to realize the alignment between the wire clamp and the hanging female. Row 21 is firmly fixed.

[0046] By setting the limiting part on the movable clamping part of the wire clamp and setting the serrated teeth on the movable clamping part and the corresponding clamping part, setting a limiting block on the side close to the opening above the fixed wire clamp body, and the positioning block and the limiting The combination of the parts realizes the firm fixing of the wire clip and the hanging busbar, prevents false hanging, improves safety, and avoids potential safety hazards.

Abstract

The invention discloses a compact low-voltage grounding wire, which comprises an insulated operation rod, a wire clamp and a soft copper wire. The insulated operation rod is divided into a plurality of different segments. All the segments of the insulated operation rod are in hinged connection. Each of the segments of the insulated operation rod is capable of being rotated and bent at any angle. The insulated operation rod is composed of a plurality of continuously connected segments, and the plurality of continuously connected segments are in hinged connection. In this way, the bending and the angle adjustment of the insulated operation rod are realized, so that the insulated operation rod is not limited by the space during the hanging process. The operation difficulty in the narrow space is lowered. Meanwhile, the condition that due to the insulated operation rod cannot be bent, the insulated operation rod is exposed out of a switch cabinet and the door of the switch cabinet cannot be closed can be avoided. In addition, the angle position of the insulated operation rod can be freely adjusted according to the requirements of the actual operation space and the actual operation position. As a result, the insulated operation rod does not hinder other objects or bus bars or is not hindered by other objects or bus bars during the operation process. The wire clamp is provided with a limiting portion and jagged teeth, so that the wire clamp can be firmly fixed to a hung bus bar. The false hanging is avoided, and the safety is improved. Potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the technical field of grounding wires, in particular to compact low-voltage grounding wires. Background technique [0002] There are deficiencies in the installation of traditional low-voltage grounding wires: [0003] (1) The structure of the insulating operation rod and the clamp is fixed, and it will be limited by the space when it is hung. Cabinet door cannot be closed. [0004] (2) When the grounding wire is hung, due to reasons such as the angle and the technical design of the grounding wire, the contact position of the conductive end is not in full contact, which will cause poor contact or even false hanging, which has certain potential safety hazards. [0005] (3) The metal part of the commonly used grounding wire clamp is too large, and the phase-to-phase distance of the current low-voltage complete power distribution device is very small, and even the distance between adjacent busbars is very small. It may acciden...
