Description

Technical Field

[0001] This utility model relates to the field of portable short-circuit grounding wire technology, specifically a portable short-circuit grounding wire for maintenance of power distribution control equipment. Background Technology

[0002] Portable short-circuit grounding wires are temporary grounding devices used in the power industry for safety protection during the maintenance of power distribution control equipment. Their main function is to prevent electric shock accidents caused by accidental energization or induced charges on equipment.

[0003] To prevent the length of the insulating operating rod from affecting operation and to reduce safety hazards, a portable short-circuit grounding wire for the maintenance of power distribution control equipment has been developed (see patent number: 201922169201.5). It includes a grounding clamp with symmetrically arranged metal clips inside. A connecting block is provided on the grounding clamp, and a grounding wire is connected to the connecting block via a connecting rod. An insulating operating rod is located below the grounding clamp. An angle adjustment device includes a fixed connecting seat with an arc-shaped groove inside. A universal ball is located on the arc-shaped groove and connected to the grounding clamp. A threaded rod is movably inserted through a limiting plate. A bearing is located at one end of the threaded rod within the arc-shaped groove, and a limiting nut is located at the other end. The insulating operating rod includes an insulating cylinder with a threaded cavity inside. A threaded extension rod is located within the threaded cavity. The advantages are: this device has a simple structure, is easy to use, and can effectively change the angle of the grounding clamp as needed.

[0004] However, existing portable short-circuit grounding wires used for the maintenance of power distribution control equipment cannot quickly disconnect the connection when a fault occurs and the power needs to be cut off during use, resulting in poor fault prevention effect and reduced utilization rate.

[0005] Therefore, a portable short-circuit grounding wire for the maintenance of power distribution control equipment is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a portable short-circuit grounding wire for the maintenance of power distribution control equipment in order to solve the problem of not being able to directly disconnect the connection in case of a fault.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable short-circuit grounding wire for maintenance of power distribution control equipment, including a movable connector, a first grounding wire is provided on one side of the movable connector, a limit ring is provided on the outer side of the first grounding wire near the movable connector, and a docking member is provided on the other side of the movable connector;

[0008] The mating member has a mating groove on one side, and an elastic element is provided inside the mating groove. The other side of the mating member has a second grounding wire extending to one side of it.

[0009] The protruding part has multiple sets of external threads evenly distributed on its exterior.

[0010] As a further embodiment of this utility model: multiple sets of internal threads matching the external threads are evenly arranged on the inner wall of the mating groove, and the protrusion is threadedly connected to the mating groove through the mutual cooperation of the external threads and internal threads.

[0011] As a further improvement of this utility model: one side of the movable connector is provided with a movable groove that matches the limiting ring, and the movable connector is movably connected to the first grounding wire through the mutual cooperation of the limiting ring and the movable groove.

[0012] As a further improvement of this utility model, the movable connector is detachably connected to the docking member through the mutual cooperation of the docking groove and the protrusion.

[0013] As a further improvement of this utility model, the movable connector has multiple sets of friction textures evenly distributed on its exterior.

[0014] As a further improvement of this utility model: the movable connector is provided with an electrical connecting piece, and the first grounding wire and the second grounding wire are electrically connected through the electrical connecting piece.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting a protrusion on one side of the movable connector to connect with the mating groove on the mating part, during connection, the protrusion moves along the mating groove to its interior and exerts a squeezing force on the elastic element inside the mating groove, causing it to deform under force and generate corresponding elastic potential energy. When squeezed to a certain extent, the movable connector can be rotated slightly, so that the external thread on the outside of the protrusion can be threadedly connected with the internal thread on the inner wall of the mating groove. The movable connector is provided with an electrical connection piece, which can realize the electrical connection between the first grounding wire and the second grounding wire.

[0017] 2. If a fault occurs and disconnection is required, the movable connector can be rotated slightly in the opposite direction. At the same time, under the rebound force of the elastic element, the protrusion will directly separate from the mating groove, and the second grounding wire will be disconnected from the electrical connection piece, thus breaking the electrical connection. This allows for quick disconnection, facilitating subsequent maintenance of the power distribution control equipment. Attached Figure Description

The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figures 1-3 In this embodiment of the utility model, a portable short-circuit grounding wire for maintenance of power distribution control equipment includes a movable connector 1. A first grounding wire 102 is provided on one side of the movable connector 1. A limit ring 103 is provided on the outer side of the first grounding wire 102 near the movable connector 1. A docking part 2 is provided on the other side of the movable connector 1.

[0025] Among them, a docking groove 201 is provided on one side of the docking member 2, an elastic element 202 is provided inside the docking groove 201, and a second grounding wire 203 extending to one side of the docking member 2 is provided on the other side of the docking member 2.

[0026] The protrusion 101 has multiple sets of external threads evenly arranged on its exterior.

[0027] like Figures 1 to 3 As shown, multiple sets of internal threads matching the external threads are evenly arranged on the inner wall of the mating groove 201. The protrusion 101 is threadedly connected to the mating groove 201 through the mutual cooperation of the external and internal threads.

[0028] like Figures 1 to 3 As shown, a movable groove matching the limiting ring 103 is provided on one side of the movable connector 1. The movable connector 1 is movably connected to the first grounding wire 102 through the mutual cooperation of the limiting ring 103 and the movable groove.

[0029] like Figures 1 to 3 As shown, the movable connector 1 is detachably connected to the docking member 2 through the mutual cooperation of the docking groove 201 and the protrusion 101.

[0030] like Figures 1 to 3 As shown, the exterior of the movable connector 1 is uniformly provided with multiple sets of friction textures to increase frictional resistance and make its operation more stable.

[0031] like Figures 1 to 3 As shown, the movable connector 1 is provided with an electrical connecting piece, and the first grounding wire 102 and the second grounding wire 203 are electrically connected through the electrical connecting piece.

[0032] Working principle: In use, the protrusion 101 on one side of the movable connector 1 is connected to the mating groove 201 on the mating part 2. During connection, the protrusion 101 moves along the mating groove 201 to its interior and exerts a squeezing force on the elastic element 202 inside the mating groove 201, causing it to deform under force and generate corresponding elastic potential energy. When squeezed to a certain extent, the movable connector 1 can be rotated slightly, so that the external thread on the outside of the protrusion 101 can be threadedly connected to the internal thread on the inner wall of the mating groove 201. The movable connector 1 is provided with an electrical connection piece, which can realize the electrical connection between the first grounding wire 102 and the second grounding wire 203.

[0033] If a fault occurs and disconnection is required, the movable connector 1 can be rotated slightly in the opposite direction. At the same time, under the rebound force of the elastic member 202, the protrusion 101 is directly separated from the mating groove 201, and the second grounding wire 203 is separated from the electrical connecting piece, thus disconnecting the electrical connection. This allows for quick disconnection.
