Description

Technical Field

[0001] The present invention relates to the technical field of grounding wires, and more specifically, to a grounding wire clip for low-voltage metering work. Background Art

[0002] The low-voltage main switch of the metering box is the RT0 base and the special fuse of the national standard "GB13539". Due to the limited space designed for the low-voltage seat box and the low-voltage metering electricity meter box, when the metering meter is damaged, power outage is required for replacement. Construction personnel cannot effectively ground. The current practice is to pull out the fuse and not ground, which violates the safety requirements of the safety regulations for electrical work. Due to the small position space of the low-voltage switch, when grounding, the fuse needs to be pulled out, one side is energized, and the grounding wire is connected to the non-energized side of the base for effective grounding. The current special wire clip for low-voltage grounding wires clips the low-voltage switch base insecurely, is easy to pop out, touches the energized end, forms a short circuit, and causes construction personnel to violate regulations and not ground. Summary of the Invention

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a grounding wire clip for low-voltage metering work, which can use the original tools to safely install the grounding wire into the switch base and avoid insecure contact.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a grounding wire clip for low-voltage metering work, including a wire clamping seat and a clamping block. The wire clamping seat is a hollow cylinder with an opening on the circumferential side, and the clamping block is a convex structure adapted to a puller, and the clamping block is arranged on the circumferential side of the bottom of the wire clamping seat.

[0005] Further, the wire clamping seat and the clamping block are made of ceramic or insulating material or metal.

[0006] Further, the clamping block is composed of a first rectangular block and a second rectangular block, and the first rectangular block is arranged in the middle of the circumferential side of the second rectangular block.

[0007] Further, the first rectangular block and the second rectangular block have the same thickness.

[0008] Further, there are two clamping blocks, and the two clamping blocks are respectively arranged at both ends of the wire clamping seat.

[0009] Further, the first rectangular block is 2-3 mm wide, preferably 2.5 mm, and 5-7 mm long, preferably 6 mm.

[0010] Further, the second rectangular block is 5-7 mm wide, preferably 6 mm, and 9-11 mm long, preferably 10 mm.

[0011] Further, the wire clamping seat is 65-70 mm long, preferably 67 mm.

[0012] Compared with the prior art, the beneficial effects are as follows:

[0013] This device can simply detach the ground wire, which is easily purchasable in the market, from the wiring clip. After simply fixing the end of the ground wire with this wire clamp, use a national standard fuse extractor to clamp the ground wire, and insert the wire end (copper wire) of the ground wire into the grounding end of the RT0 socket for firm contact, meeting the requirements of the grounding current of the ground wire and also meeting the needs of power grid operation. Description of the Drawings

[0014] Figure 1 It is the front view of the overall structure of the present invention. Detailed Embodiment

The positional relationships described in the drawings are only for illustrative purposes and should not be construed as a limitation to this patent.

[0016] As Figure 1 shown, a wire clamp for a low-voltage metering working ground wire includes a wire clamping seat and a clamping block. The wire clamping seat is a hollow cylinder with an opening on its circumferential side, and the clamping block is a convex structure adapted to the extractor. The clamping block is arranged on the circumferential side at the bottom of the wire clamping seat.

[0017] In this embodiment, the wire clamping seat and the clamping block are made of ceramic, insulating material or metal.

[0018] In this embodiment, the clamping block is composed of a first rectangular block and a second rectangular block, and the first rectangular block is arranged in the middle of the circumferential side of the second rectangular block.

[0019] In this embodiment, the first rectangular block and the second rectangular block have the same thickness.

[0020] In this embodiment, there are two clamping blocks, and the two clamping blocks are respectively arranged at both ends of the wire clamping seat.

[0021] In this embodiment, the first rectangular block has a width of 2 - 3 mm, preferably 2.5 mm, and a length of 5 - 7 mm, preferably 6 mm.

[0022] In this embodiment, the second rectangular block has a width of 5 - 7 mm, preferably 6 mm, and a length of 9 - 11 mm, preferably 10 mm.

[0023] In this embodiment, the wire clamping seat has a length of 65 - 70 mm, preferably 67 mm.

[0024] The usage process of this device is as follows:

[0025] This device can simply detach the grounding wire that is easily purchasable in the market from the wiring clip. After the end of the grounding wire is simply fixed in the wire clamping seat, the national standard fuse extractor is used to clamp the grounding wire, and the wire end (copper wire) of the grounding wire is inserted into the grounding end required by the RT0 seat for firm contact, meeting the requirements of the grounding current of the grounding wire.
