Technical Field
[0001] This utility model relates to the field of non-tightening grounding wire technology, specifically to a non-tightening grounding wire. Background Technology
[0002] A non-tightening grounding wire (also called a screwless grounding wire) is a type of grounding wire used in electrical equipment grounding systems. Its connection method does not require tightening screws or other similar fixing methods. It is typically designed for easy and quick installation, reducing human error, and improving the reliability of the grounding system.
[0003] Existing non-tightening grounding wires mainly consist of a connecting conductor and clamps installed at both ends of the connecting conductor. Although existing non-tightening grounding wires can achieve rapid grounding of electrical equipment during short-term maintenance by clamping, the clamps are not reliably limited during the clamping process and are easily opened by mistake, resulting in poor grounding of electrical equipment and causing safety hazards.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] like Figures 1-3 As shown, a non-tightening grounding wire in this embodiment includes a connecting wire 3, with a connecting copper sleeve 2 connected to each end of the connecting wire 3. A clamping assembly 1 is installed on the side of the connecting copper sleeve 2 facing away from the connecting wire 3. The clamping assembly 1 is mainly used to clamp the grounding rod on the electrical equipment and the ground. The clamping assembly 1 includes a pull plate 101, a spring 102, a pull rod 103, a movable clamping plate 104, and a fixed clamping plate 105. An anti-loosening assembly 4 is installed on one side wall of the fixed clamping plate 105. The anti-loosening assembly 4 includes a limiting post 401, a pull cover 402, a spring 403, and a limiting hole 404. Under the action of the anti-loosening assembly 4, the grounding wire can reliably limit the movable clamping plate 104 in the clamping assembly 1 after being clamped, with the cooperation of the limiting post 401 and the limiting hole 404. This effectively reduces the risk of the clamping assembly 1 being accidentally opened under shaking conditions, making the grounding wire safer to use.
[0025] like Figures 1-3 As shown, in this embodiment, the connecting copper sleeve 2 is welded to the fixed clamping plate 105, and the exposed end of the connecting copper sleeve 2 is inserted into the connecting wire 3. The connecting copper sleeve 2 is mainly used to ensure a reliable connection between the connecting wire 3 and the fixed clamping plate 105, so as to achieve reliable grounding of the clamping assembly 1 after clamping by means of the connecting wire 3. The pull rod 103 is installed in the middle of the fixed clamping plate 105, and the pull plate 101 is welded to one end of the pull rod 103. The pull plate 101 facilitates the easy pulling of the movable clamping plate 104. The movable clamping plate 104 is welded to the pull rod 103 facing away from the pull plate. At one end of 101, a pull rod 103 passes through a fixed clamping plate 105 and slides with the fixed clamping plate 105. The pull rod 103 is mainly used to facilitate the pulling of the movable clamping plate 104, so as to facilitate the placement of cables on electrical equipment between the movable clamping plate 104 and the fixed clamping plate 105. The pull rod 103 passes through a spring 102. One end of the spring 102 is inserted into the fixed clamping plate 105, and the other end of the spring 102 is inserted into the pull plate 101. The spring 102 is mainly used to realize the automatic reset of the movable clamping plate 104 after being pulled.
[0026] like Figures 1-3 As shown, in this embodiment, the limiting hole 404 is opened in the middle of one side wall of the movable clamping plate 104. The size of the limiting post 401 matches the size of the limiting hole 404. The limiting hole 404 and the limiting post 401 cooperate to ensure the reliable anti-loosening limit of the movable clamping plate 104 after clamping, and to prevent the movable clamping plate 104 from being accidentally opened when shaking. One end of the limiting post 401 is welded to the pull cover 402. The pull cover 402 consists of a square cover and a pull head installed on the outside of the square cover. The pull cover 402 facilitates the convenient pulling of the limiting post 401. The limiting post 401 passes through the second spring 403. The two ends of the second spring 403 are respectively inserted into the pull cover 402 and the concave structure on the fixed clamping plate 105. The second spring 403 is mainly used to realize the automatic reset of the limiting post 401 after being pulled outward.
[0027] The specific implementation process of this embodiment is as follows: When performing short-term maintenance on electrical equipment, firstly, the movable clamp 104 is pulled outward relative to the fixed clamp 105. Then, the cables on the electrical equipment and the grounding rod on the ground are placed between the movable clamp 104 and the fixed clamp 105. At this time, the pull cover 402 is also in the outward pulling state, and the limiting post 401 is retracted in the side wall of the fixed clamp 105. Then, simply release the pull rod 103 to allow the movable clamp 104 to reset under the action of the spring 102, thereby realizing the maintenance of the cables on the electrical equipment and the grounding rod on the ground. The grounding rod is clamped, and then the pull cover 402 is released, so that the limiting post 401 is inserted into the limiting hole 404 under the action of the second spring 403, and the grounding wire can be put into use. During use, under the action of the anti-loosening component 4, the grounding wire can reliably limit the movable clamping plate 104 in the clamping component 1 after being clamped, with the cooperation of the limiting post 401 and the limiting hole 404. This effectively reduces the risk of the clamping component 1 being accidentally opened under shaking, making the grounding wire safer to use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
