Abstract
The utility model discloses a grounding wire clip used for testing which belongs to the field of power transmission, and comprises a wire clip body, wherein a bolt is fixed on the wire clip on body, a lower side plate of the wire clip body is provided with a threaded hole, a rotating part is arranged in the threaded hole, the top end of the rotating part is provided with a fastener, and the inner side of an upper side plate of the wire clip body is provided with saw teeth which comprise triangular saw teeth and rectangular saw teeth. In the utility model, the saw teeth arranged at the inner side of the upper side plate of the wire clip body are the triangular saw teeth and the rectangular saw teeth which are arranged at intervals, the bottoms of the triangular saw teeth are relatively sharp so as to wear off an insulating layer on a grounding down wire, while the rectangular saw teeth can ensure better contact between the wire clip and the grounding down wire.
Description
Technical field
The utility model belongs to field of power transmission, is specifically related to a kind of earthing clamp of testing usefulness.
Background technology
In electric power apparatus examination and maintenance process, need be fixed on the down conductor with earthing clamp, existing earthing clamp as shown in Figure 1, comprise wire clip body 2, be fixed with bolt 6 on the wire clip body 2, wire clip body 2 lower side panels are provided with screwed hole, be provided with revolving part 7 in the screwed hole, revolving part 7 tops are provided with securing member 3, wire clip body 2 epipleural inboards are provided with sawtooth, sawtooth on this device all is triangular in shape, when the surface oxidation of down conductor or surface have when insulating barrier such as spraying paint, by moving of earthing clamp, utilize leg-of-mutton sharp sawtooth to grind off the insulating barrier on down conductor 1 surface, can realize being communicated with between wire clamp and the down conductor 1, but owing to be a contact or line contact between triangle sawtooth bottom and the down conductor, the contact between wire clamp and the down conductor 1 is still undesirable.
The utility model content
The technical problems to be solved in the utility model be earthing clamp with down conductor between contact badly, a kind of test earthing clamp that can well contact with down conductor is provided.
The technical solution of the utility model realizes in the following manner:
A kind of test earthing clamp, comprise wire clip body, be fixed with bolt on the wire clip body, the wire clip body lower side panel is provided with screwed hole, be provided with revolving part in the screwed hole, the revolving part top is provided with securing member, and wire clip body epipleural inboard is provided with sawtooth, and described sawtooth comprises triangle sawtooth and rectangle sawtooth.
Described triangle sawtooth and rectangle zigzag intervals distribute.
Described securing member end face is provided with triangle sawtooth spaced apart and rectangle sawtooth.
In the utility model, the sawtooth of wire clip body epipleural inboard is that triangle and rectangle are spaced, the bottom of triangle sawtooth is more sharp-pointed, can grind off the insulating barrier on the down conductor, and the rectangle sawtooth then can be so that the contact gear ratio between wire clamp and the down conductor be better.

Fig. 1 is the user mode figure of prior art.
Fig. 2 is the user mode schematic diagram of the utility model embodiment 1.
Fig. 3 is the user mode schematic diagram of the utility model embodiment 2.
Embodiment
As shown in Figure 2, present embodiment comprises wire clip body 2, be fixed with bolt 6 on the wire clip body 2, wire clip body 2 lower side panels are provided with screwed hole, be provided with revolving part 7 in the screwed hole, revolving part 7 tops are provided with securing member 3, and wire clip body 2 epipleural inboards are provided with sawtooth, and described sawtooth comprises triangle sawtooth 5 and rectangle sawtooth 4.Described triangle sawtooth 5 and rectangle sawtooth 4 are spaced apart.
The utility model use is as follows: the top that down conductor 1 is placed on securing member 3, turning revolving part 7 moves up securing member 3, clamp down conductor, if there is insulating barrier on down conductor 1 top layer, move left and right wire clip body then, utilize triangle sawtooth 5 to grind off insulating barrier, making has excellent contact between wire clamp and the down conductor.
As shown in Figure 3, securing member 3 end faces are provided with triangle sawtooth 5 spaced apart and rectangle sawtooth 4.Other structures and execution mode are with embodiment 1.
