Description

Technical Field

[0001] The utility model relates to the technical field of electric test grounding rings, in particular to an electric test grounding ring that is easy to use. Background Art

[0002] At present, overhead insulated wires are generally used for laying medium and low voltage lines in urban distribution networks. When inspecting lines or equipment, in order to ensure the safety of maintenance personnel, it is necessary to verify that the lines are without electricity and then hang up the grounding protection wire. This requires that the grounding wire clamp must be in reliable contact with the wire when hanging the grounding wire, but insulated wires cannot be hung, so an electrical inspection grounding ring is used.

[0003] The existing grounding ring is usually a ring-shaped closed structure, which makes it inconvenient to connect the grounding ring and the grounding wire. Therefore, in order to facilitate the connection between the grounding wire and the grounding ring, some electrical testing grounding rings will be provided with an opening on the grounding ring, so that the grounding wire can be directly put on the grounding ring through the opening, so as to achieve the purpose of convenient connection; however, since the grounding ring is provided with an opening, the grounding wire is easy to fall from the opening of the grounding ring when affected by wind shaking, thereby affecting normal use, and the grounding ring is usually provided with a parallel groove wire clamp, and the insulating protective shell on the parallel groove wire clamp is usually a split structure, which makes it cumbersome and inconvenient to install.

[0010] Beneficial Effects

[0011] The above one or more technical solutions in the convenient-to-use electrical test grounding ring provided by the embodiment of the utility model have at least one of the following technical effects:

[0012] The utility model adopts the above technical scheme, when installing the grounding wire, by pushing the blocking rod to make the blocking rod rotate, the blocking of the opening of the grounding ring body is cancelled. At that time, the grounding wire can be inserted into the grounding ring body through the opening, and the blocking rod is pushed back to block the opening by the elastic force of the spring sheet. The utility model not only facilitates the connection between the grounding wire and the grounding ring body, but also avoids the problem that the grounding wire is easy to fall from the opening of the grounding ring body when shaken by wind, thereby ensuring the connection stability; and the upper shell and the lower shell of the insulating protective shell are connected by rotation, which makes it more convenient to put the insulating protective shell on the outside of the parallel groove wire clamp, thereby accelerating the installation efficiency.

[0023] In this embodiment, the invention comprises a parallel groove wire clamp 1, a grounding ring body 2, and an insulating protective shell 3. The grounding ring body 2 is arranged in an annular structure. An opening 4 is arranged on one side of the grounding ring body 2. A baffle rod 5 is rotatably arranged on the top of the opening 4. The baffle rod 5 is made of high temperature resistant plastic material. A first limit block 6 is arranged on the outer side of the bottom of the opening 4. A second limit block 7 is arranged on one side of the bottom of the baffle rod 5. The first limit block 6 abuts against the second limit block 7 to limit the baffle rod 5. The surface of the grounding ring body 1 is covered with an insulating layer 8. The insulating ability of the grounding ring body 2 is enhanced by the insulating layer 8. A spring piece 9 is arranged on one side of the top of the grounding ring body 2 near the opening 4. The spring piece 9 is made of stainless steel and has good elastic force. The other end of the spring piece 9 is connected to the inner side of the baffle rod 5. The spring piece 9 provides elastic force to the baffle rod 5. When the baffle rod 5 is pushed to rotate, the spring piece 9 is squeezed and bent and stores elastic potential energy. When the push of the baffle rod 5 is cancelled, the spring piece 9 elastically resets and pushes The movable stop rod 5 is reset, the parallel groove clamp 1 includes an upper clamp 10 and a lower clamp 11, and the upper clamp 10 and the lower clamp 11 are provided with two clamping grooves 12 on the opposite end faces, and the grounding ring body 2 is clamped by the clamping grooves 12. The surface of the clamping grooves 12 is provided with saw teeth 13, and the saw teeth 13 increase the friction of the clamping grooves 12 to avoid rotation between the grounding ring body 2 and the parallel groove clamp 1. The insulating protective shell 3 includes an upper shell 14 and a lower shell 15, and the upper shell 14 and the lower shell 15 are provided with saw teeth 13.

The insulation effect of the parallel groove wire clamp 1 is ensured by the insulating protective shell 3. When the grounding wire is installed, the blocking rod 5 is pushed to rotate away from the opening 4 and cancel the covering of the opening of the grounding ring body. At that time, the grounding wire can be sleeved in the grounding ring body through the opening, and the elastic force of the spring sheet pushes the blocking rod to reset and cover the opening.

[0024] In this embodiment, the insulating layer 8 is made of insulating silicone rubber. The insulating layer 8 ensures the insulation capability of the grounding ring body 2. The grounding ring body 1 is designed with silicone rubber coating, which can effectively consume the vibration energy of the wire.
