Description

Technical Field

[0001] This utility model relates to a grounding clamp, and more particularly to a stripping grounding clamp, belonging to the field of power fittings technology. Background Technology

[0002] Grounding clamps are commonly used in power distribution lines with a rated voltage of 10kV and below. They facilitate the connection of grounding wires and effectively prevent injury to personnel caused by accidental backfeeding or induced current when construction and maintenance personnel are working, thus ensuring the safety of maintenance personnel.

[0003] Grounding clamps come in two types: piercing and stripping. Piercing clamps connect to the wire by piercing the wire sheath with sharp points, which can damage the wire during use. Stripping clamps, on the other hand, are installed using torque bolt clamps, which do not damage the wire during the crimping process, helping to ensure the performance and lifespan of the conductor. However, the contact ring of existing stripping clamps is usually exposed, and accidental contact can cause electric shock, posing a certain safety hazard. Summary of the Invention

[0004] To address the aforementioned shortcomings, this utility model provides a stripping grounding clamp with all-around insulation protection.

[0005] To achieve the above objectives, this utility model employs a stripping grounding clamp, comprising a clamp body, a slider, a pad, and a torque bolt. The clamp body includes an integrally formed clamp seat and a grounding ring. An opening is formed on one side of the clamp seat. The slider is disposed on the opening of the clamp seat. The torque bolt passes through the slider. The pad is connected to the top of the torque bolt that extends into the clamp seat. A clamp cover is provided outside the clamp seat. The clamp cover includes an upper outer cover and a lower outer cover. The outer ends of the upper and lower outer covers are hinged to each other. A buckle is provided on the inner end of the lower outer cover. A snap-fit ​​block is formed on the inner end of the upper outer cover corresponding to the buckle. The buckle and the snap-fit ​​block engage in a snap-fit ​​connection.

[0006] This utility model uses a torque bolt clamping block for installation, which is not only easy to operate, but also does not damage the wires during the crimping process, helping to ensure the performance and life of the wires. At the same time, the wire clamp cover provides all-round insulation protection for the equipment. When performing voltage testing and grounding operations, you only need to pull open the wire clamp cover to directly connect the ground wire. The operation is simple and direct. After the construction is completed, the wire clamp cover can be pulled back to its original position and covered.

[0007] Specifically, the grounding ring is provided with a plastic sleeve that extends into the inside of the clamp cover, the outer end of the grounding ring is exposed outside the plastic sleeve, and a grounding ring cover is provided outside the outer end of the grounding ring.

[0008] Specifically, the grounding ring includes an inner straight rod and an outer straight rod connected at their top ends, the inner straight rod and the outer straight rod are connected in an L-shape, and the grounding ring cover is disposed outside the outer straight rod.

[0009] Specifically, the buckle includes a small buckle and a large buckle. The small buckle is hinged to the lower outer cover, and the large buckle is hinged to the small buckle. A locking ring is formed on the large buckle. The locking ring can be fitted onto the locking block of the upper outer cover to lock the upper and lower outer covers.

[0010] The beneficial effects of this utility model are that it provides all-round insulation protection for the equipment by using the wire clamp cover, plastic sleeve and grounding ring cover. The wire clamp cover protects the wire clamp seat, and the plastic sleeve and grounding ring cover eliminate the risk of electric shock caused by accidental contact with the grounding ring due to partial exposure. This greatly improves the safety during use and provides reliable protection for power workers and people in the surrounding area. Attached Figure Description

[0014] like Figures 1-3 As shown, a specific embodiment of this utility model is a stripping grounding clamp, including a clamp body, a slider 3, a pad 4, a torque bolt 5, a clamp cover 6, a plastic-coated sleeve 7, and a grounding ring cover 8. The clamp body includes an integrally formed clamp seat 1 and a grounding ring 2. An opening is formed on one side of the clamp seat 1. The slider 3 is disposed on the opening of the clamp seat 1. The torque bolt 5 passes through the slider 3. The pad 4 is connected to the top of the torque bolt 5 that extends into the clamp seat 1. The clamp cover 6 is disposed outside the clamp seat 1. The clamp cover 6 includes... The upper outer cover 61 and the lower outer cover 62 are hinged to each other at their outer ends. The inner end of the lower outer cover 62 is provided with a buckle, which includes a small buckle 64 and a large buckle 65. The small buckle 64 is hinged to the lower outer cover 62, and the large buckle 65 is hinged to the small buckle 64. A locking ring 66 is formed on the large buckle 65. The inner end of the upper outer cover 61 forms a locking block 63 corresponding to the locking ring 66 of the large buckle 65. The locking ring 66 can be fitted onto the locking block 63 to lock the upper outer cover 61 and the lower outer cover 62.

[0015] A plastic-coated sleeve 7 is installed on the grounding ring 2 and extends into the wire clamp cover 6. The outer end of the grounding ring 2 is exposed outside the plastic-coated sleeve 7. The grounding ring 2 includes an inner straight rod and an outer straight rod that are connected to each other at their top ends.
