Description
Technical Field
The invention relates to the field of power electricity, in particular to a low-voltage grounding wire hanging terminal device of a low-voltage cable branch box.
Background
The current grounding mode of the low-voltage cable branch box is realized by clamping a grounding wire clamp on a bolt of an outdoor branch box and then grounding. However, in general, since the bolt on the branch box is short and most of the bolts are located at the inner position of the branch box, the grounding wire clamp is difficult to clamp on the bolt during grounding operation, and even if the grounding wire clamp is clamped, the grounding wire clamp is easy to fall off due to the fact that the grounding wire clamp is not deep enough during operation, so that the grounding operation on the branch box is inconvenient, and the work efficiency is reduced. In addition, the grounding wire falls off in the operation process, so that safety accidents are easily caused, and the consequences are unreasonable. Therefore, a new type of fixing and connecting device for the grounding wire of the low-voltage cable branch box is urgently needed to solve the practical problem.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, provides the terminal device for hanging the low-voltage grounding wire of the low-voltage cable branch box, replaces the traditional bolt at present, and solves the problems that the bolt length of the low-voltage cable branch box is short and the grounding wire clamp cannot be fixed.
The purpose of the invention is achieved by the following technical scheme: the low-voltage grounding wire hanging terminal device of the low-voltage cable branch box mainly comprises a body, wherein the body consists of a fixing section and a wire clamp clamping section which are arranged in front and back, the fixing section is installed on a box body of the cable branch box and is fixedly connected with a nut through threads on the outer surface of the fixing section, a threaded hole is formed in the center of the fixing section, and a grounding wire clamp is directly hung on the wire clamp clamping section to realize grounding operation; the length of the wire clamp clamping section is far longer than the length required by the clamping of the grounding wire clamp.
As an improvement on the structure of the invention, the tail part of the wire clamp clamping section is provided with a flange.
As a further improvement of the invention, one side of the wire clamp clamping section is provided with a spring mounting groove, one end of the spring is connected to the spring mounting groove, the other end of the spring is propped against the sliding block, and the grounding wire clamp is clamped between the sliding block and the flange.
Further, the distance between the sliding block and the flange is smaller than the length required by clamping the grounding wire clamp.
The invention has the beneficial effects that: the invention has simple structure, convenient use, safety and reliability; replace traditional bolt for ground clamp can fully centre gripping on fastener centre gripping section, guarantees can not take place to drop in operation process, has improved operating personnel's work efficiency, ensures operating personnel's life safety simultaneously.

Detailed Description
The invention will be described in detail below with reference to the following drawings:
example 1: as shown in the attached drawing 1, the low-voltage grounding wire hanging terminal device of the low-voltage cable branch box mainly comprises a body 1, wherein the body 1 consists of a fixing section 2 and a wire clamp clamping section 3 which are arranged in front and back, the fixing section 2 is installed on a box body of the cable branch box and is fixedly connected with a nut through threads on the outer surface of the fixing section 2, a threaded hole 4 is formed in the center of the fixing section 2, and a grounding wire clamp is directly hung on the wire clamp clamping section 3 to realize grounding operation; the length of the wire clamp clamping section 3 is far greater than the length required by clamping the grounding wire clamp, so that the clamping depth of the grounding wire clamp is ensured.
Preferably, the depth of the threaded hole 4 is 35mm, and the length of the body 1 is 200 mm.
Example 2: as shown in fig. 2, the difference from embodiment 1 is that the tail of the clip holding section 3 is provided with a flange 5 for limiting the position of the ground clip, and ensuring that the ground clip will not slip off the tail of the clip holding section 3 after being pulled.
Example 3: as shown in fig. 3, the difference from embodiment 2 is that a spring mounting groove 6 is opened at one side of the wire clamp holding section 3, one end of a spring 7 is connected to the spring mounting groove 7, the other end of the spring is pressed against a slide block 8, the ground wire clamp is held between the slide block 8 and a flange 5, and the distance between the slide block 8 and the flange 5 is less than the length required for holding the ground wire clamp. The grounding wire clamp is clamped between the sliding block 8 and the flange 5 for fixing during clamping, and the grounding wire clamp cannot slip off the wire clamp clamping section 3 due to the influence of tearing.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
