Abstract
The utility model discloses a grounding protective wire clamp of a cable terminal. The wire clamp comprises a door-shaped framework, the door-shaped framework is formed by connecting a crossbeam with frames at the two sides of the crossbeam, one frame is provided with a screw hole, a bolt penetrates through the through hole, one end of the bolt is fixedly connected with a clamping block, the clamping block is placed inside the door-shaped framework, the other end of the bolt is fixed to a nut, and one of the two frames is fixedly connected with a grounding wire. The wire clamp can be directly connected with the cable terminal to ensure that the cable terminal is always grounded when being dismounted from a busbar.
Description
Technical field
The utility model relates to a kind of electrician's apparatus, in particular to a kind of cable terminal ground protection wire clamp.
Background technology
In power supply routine work, the cable terminal in switch cabinet of converting station is owing to being protected by pyrocondensation insulating material, and common earthing clamp can only be clipped on the busbar of cable terminal junction, and cannot directly be connected on cable terminal.In the time that cable work is removed or changed to needs, when cable terminal is removed from busbar, because separating with busbar, original connecting wires can not make cable terminal continue ground connection, and this makes that the operation of cable terminal is had to certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of cable terminal ground protection wire clamp, and this wire clamp can directly be connected on cable terminal, thereby ensures that cable terminal also can moment ground connection when busbar unloads.
For achieving the above object, the utility model is taked following technical scheme:
A kind of cable terminal ground protection wire clamp; comprise a type frame; it is characterized in that; described door type frame is formed by connecting by the frame of crossbeam and crossbeam both sides, and wherein a side frame is provided with screw, and bolt is through described screw; be fixedly connected with clamp in bolt one end; described clamp is positioned at a type frame, is fixed with nut at the bolt other end, on one of described both sides frame, is fixedly connected with earth connection.
Described clamp and described bolt are perpendicular.
Described earth connection is fixedly connected on the lower end of the frame with described screw.
Described nut is pentagon nut or hex nut.
In the utility model, utilize door type frame and clamp to clamp after cable terminal, make the ground connection of connecting wires of wire clamp, after busbar is unloaded down, can keep all the time like this cable terminal ground connection at cable terminal, thereby eliminate safe hidden trouble.
Brief description of the drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is that the utility model uses view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, frame 1 and frame 8 that door type frame 10 is connected with crossbeam 7 two ends by crossbeam 7 are formed by connecting, on frame 8, leave screw 9, bolt 3 is through screw 9, one end is vertically fixed with clamp 2, and the other end is equipped with nut 4, and clamp 2 is positioned at a type frame 10, nut 4 is positioned at type frame 10 outside, and nut 4 is pentagon nut or hex nut.6 lower ends that are connected to frame 8 of connecting wires, are fixed (earth connection 6 also can be connected on frame 1) by rivet 5.In use, be enclosed within on cable terminal 11 with a door type frame 7, then rotary nut 4 advances bolt 3, until clamp 2 is clamped cable terminal 11, earth connection 6 carries out ground connection.Can ensure cable terminal ground connection all the time in operation like this, thereby eliminate safe hidden trouble.
Be more than to explanation of the present utility model and non-limiting, under above-mentioned spirit instructs, also have other apparent conversion also in the utility model protection range.
