Description

Technical Field

[0001] This utility model relates to an insulation protection device for live wiring in an electricity meter, belonging to the field of power tool technology. Background Technology

[0002] When wiring electricity meters, wire strippers and needle-nose pliers are typically required. Existing wire strippers and needle-nose pliers are all one-piece designs. While this ensures a certain level of strength and durability, the insulation between the pliers and the operator's hand is only achieved through an insulating sleeve on the handle. Because the pliers are frequently dropped or subjected to other impacts during use, the insulation layer often becomes damaged or torn, potentially causing electric shock accidents to the operator.

[0003] Since wiring operations do not require the high strength and load-bearing capacity of pliers, designing a live wiring pliers with better insulation and practicality is of great significance for practical applications. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an insulation protection device for live wiring of electricity meters, which solves the technical problem that live wiring tools are prone to electric shock in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An insulation protection device for live wiring of an electricity meter includes a clamp body and a clamping part detachably connected to the front end of the clamp body. The hand-held part of the clamp body has an insulating sleeve for gripping. There are two clamping parts, each detachably connected to the front end of the clamp body. The side of the clamping part is provided with a stripping part that can be clamped relative to it. The stripping part is provided with several stripping grooves that match the wire diameter. The clamping part is made of non-metallic material. An insulating protective plate is provided on the outside of the clamping part.

[0006] Preferably, in the aforementioned insulation protection device for live wiring of an electricity meter, the tail end of the clamping part is provided with a socket, and the front end of the clamp body is connected to the socket through a plug-in part.

[0007] Preferably, in the aforementioned insulation protection device for live wiring of an electricity meter, the insulation plate extends from the stripping part to the clamp body, the side of the clamp body is provided with a wedge-shaped buckle, and the inner side of the insulation plate is provided with a snap-fit ​​groove. When the clamping part is installed on the clamping part, the wedge-shaped buckle snaps into the snap-fit ​​groove.

[0008] Preferably, in the aforementioned insulation protection device for the live wiring of an electricity meter, the cross-section of the plug portion is a rounded rectangular structure.

[0009] Preferably, in the aforementioned insulation protection device for live wires of an electricity meter, the stripping part is provided with at least two open slots, which are installed on the side of the clamping part by screws.

[0010] Preferably, in the aforementioned insulation protection device for the live wiring of an electricity meter, the clamping part is made of polytetrafluoroethylene or nylon.

[0011] Preferably, in the aforementioned insulation protection device for live wiring of an electricity meter, the opening direction of the slot is opposite to the direction of the wire stripping groove.

[0012] Preferably, in the aforementioned insulation protection device for the live wiring of an electricity meter, the plug and the socket are interference fit.

[0013] Preferably, in the aforementioned insulation protection device for live wiring of an electricity meter, the front end of the clamp body extends outward relative to the wire stripping part.

[0014] The beneficial effects achieved by this utility model are: Compared to existing technologies, this invention can perform wire stripping and wiring operations separately. Because the clamping part is made of a non-metallic material, the electricity on the wire will not be transmitted to the clamp body, and even if the insulating sleeve is damaged, it will not affect the operator's safety.

[0015] The clamping part and the clamp body adopt a plug-in disassembly structure. After the two are plugged in, they can be fixed by hooking the wedge-shaped buckle with the insulating guard plate. The operation is convenient and the connection is reliable. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0018] like Figures 1 to 4As shown: This embodiment discloses an insulation protection device for live wiring of an electricity meter, including a clamp body 1 and a clamping part 3 detachably connected to the front end of the clamp body 1. In this embodiment, the "front end" refers to the section away from the hand, that is, the end closest to the live end during operation. The clamping part 3 is what is commonly referred to as the jaws.

[0019] In this embodiment, the clamping part 3 is connected to the clamp body 1 as follows: a socket 32 ​​is provided at the tail of the clamping part 3, and the front end of the clamp body 1 is connected to the socket 32 ​​through a plug-in part 11. Furthermore, the plug-in part 11 and the socket 32 ​​are in an interference fit relationship. To prevent the clamping part 3 from rotating relative to the clamp body 1, the cross-section of the plug-in part 11 is preferably a rounded rectangular structure. Similarly, the inner hole of the socket 32 ​​also matches the cross-sectional contour of the plug-in part 11.

[0020] The gripper 1 has an insulating sleeve 2 for holding, and two clamping parts 3, which are detachably connected to the front end of the gripper 1. The clamping parts 3 are made of non-metallic material, and to ensure their strength, the material of the clamping parts 3 is polytetrafluoroethylene or nylon.

[0021] This embodiment also integrates a wire stripping function. Specifically, a wire stripping part 4 is provided on the side of the clamping part 3 for relative clamping. The wire stripping part 4 has several wire stripping grooves 41 that match the wire diameter. The installation method between the wire stripping part 4 and the clamping part 3 is as follows: the wire stripping part 4 has at least two opening slots 42, which are installed on the side of the clamping part 3 by screws 31. The distance between the two oppositely arranged wire stripping parts 4 can be controlled by rotating the screws 31, and the wire stripping part 4 can also be replaced. The opening direction of the opening slots 42 is opposite to the direction of the wire stripping grooves 41.

[0022] During live wiring, it is relatively easy for adjacent live cables to come into contact with other cables and conduct electricity. In practice, there are many accidents caused by this reason. In order to avoid this phenomenon during wire stripping or wiring, an insulating protective plate 5 is provided on the outside of the clamping part 3. The insulating protective plate 5 prevents the adjacent cables from coming into contact with the clamped or stripped cables.

[0023] Furthermore, the insulating sheath 5 extends from the stripping part 4 to the clamp body 1. The clamp body 1 has a wedge-shaped buckle 12 on its side, and a locking groove 51 on the inner side of the insulating sheath 5. When the clamping part 3 is installed on the clamping part 3, the wedge-shaped buckle 12 engages with the locking groove 51. The wedge-shaped buckle 12 is similar to a buckle with a triangular cross-section in the prior art, while the insulating sheath 5 is made of plastic and has a certain degree of elasticity, allowing it to bend elastically away from the clamp body 1. When the clamping part 3 is connected to the clamp body 1, Figure 4The black arrow in the diagram indicates that the plug part 11 is inserted into the interior of the socket 32. At this time, the wedge-shaped buckle 12 enters the interior of the snap-fit ​​groove 51, and the insulating guard plate 5 springs back towards the clamp body 1, thereby preventing the clamping part 3 from separating from the clamp body 1.

[0024] In use, first assemble the clamping part 3, the clamp body 1, and the stripping part 4. Hold the stripping part 4 of the clamp body 1 and strip the wire using it. You may need to use other needle-nose pliers to complete the stripping. Since the cable needs to be clamped after stripping, the front end of the clamp body 1 extends outward relative to the stripping part 4. In other words, the front end of the clamp body 1 needs to have a portion reserved for clamping the cable for wiring operations. Clamp the cable with the front end of the clamp body 1 and insert it into the wiring hole of the electricity meter. Then, tighten the cable with a screwdriver. When the clamping part 3 needs to be replaced, simply bend the front end of the insulating plate 5 away from the clamping part 3 to separate the wedge-shaped buckle 12 from the locking groove 51 to separate the clamping part 3 from the clamp body 1.

[0025] Compared to existing technologies, this embodiment can perform wire stripping and wiring operations separately. Because the clamping part 3 is made of non-metallic material, the electricity on the wire will not be transmitted to the clamp body 1, and even if the insulating sleeve 2 is damaged, it will not affect the operator's safety.

[0026] The clamping part and the clamp body 1 adopt a plug-in disassembly structure. After the two are plugged in, they can be fixed by hooking the wedge-shaped buckle 12 with the insulating guard plate 5. The operation is convenient and the connection is reliable.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
