Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wire clamp, specifically is a grounding wire clamp. BACKGROUND

[0002] With the development of electrical engineering, the safety of electrical equipment is paid more and more attention. Grounding is one of the most important links in electrical system, which can effectively prevent personal injury and equipment damage caused by electric leakage. The traditional grounding wire clamp usually includes a grounding ring and a wire clamp body, and the grounding ring is connected with the wire clamp body through a rod. In order to achieve reliable grounding effect, a section of unprotected light rod is usually left at some position of the rod, so as to effectively connect with the grounding device. The grounding wire clamp disclosed in the application number 201620064415X can be referred to as the conventional grounding wire clamp.

[0003] However, this design has certain safety hazards. Specifically, the completely exposed light rod not only increases the possibility of the device being affected by the external environment (such as corrosion), but also may cause electric shock accident due to accidental touch during operation. In addition, the exposed light rod may also reduce the grounding effect due to poor contact, thereby affecting the stability of the entire electrical system.

[0004] In order to solve the above problems, the prior art attempts to improve the safety and reliability of the grounding wire clamp by adding additional protective measures. For example, insulating sleeves are arranged at both ends of the rod of the grounding ring, and the light rod part between the two insulating sleeves is not covered. Although this design can reduce the influence of environmental factors on the light rod to a certain extent, it still cannot completely avoid the safety hazards mentioned above.

[0005] Therefore, a new grounding wire clamp structure is needed, which can effectively shield the light rod when not in use, and can conveniently and quickly expose the light rod for connection when grounding is needed, so as to improve the safety and practicality of the grounding wire clamp. SUMMARY

[0006] The utility model provides a grounding wire clamp in view of the deficiency in the prior art.

[0007] The technical scheme adopted by the utility model is: a grounding wire clamp, including a grounding ring and a wire clamp body, the side of the grounding ring is a rod connected with the wire clamp body, and insulating sleeves are fixed on both sides of the grounding ring, the insulating sleeves are left with a light rod for grounding between them, the insulating sleeves on both sides of the light rod are provided with sliding grooves, the sliding grooves are slidably connected with insulating sleeves, the insulating sleeves and the bottom of the sliding groove are sleeved with springs, and the springs have a spring force to push the insulating sleeves out of the sliding groove.

[0008] Further, the grounding ring is a rectangular annular structure.

[0009] Further, the wire clamp body comprises a mounting base plate, a wire clamp base plate, a wire clamp pressing plate, a bolt assembly one for connecting the mounting base plate, the wire clamp base plate and the wire clamp pressing plate in series, and a bolt assembly two for connecting the mounting base plate and the wire clamp base plate in series, the mounting base plate and the wire clamp base plate are provided with connecting holes for connecting the rod part, and the wire clamp base plate and the wire clamp pressing plate are both provided with half-ring clamping grooves for clamping the wire.

[0010] Further, a plurality of convex patterns are arranged on the inner wall of the half-ring clamping groove.

[0011] Further, the connecting hole and the rod part are in polygonal structure.

[0012] Further, the connecting hole and the rod part are in equilateral hexagonal structure.

[0013] The beneficial effects of the utility model are:

[0014] 1. Improve safety: when not in use, the insulating sleeve automatically slides out under the action of the spring and completely covers the polished rod, reducing the time of the polished rod exposed to the outside, avoiding the risk of electric shock caused by accidental touch, and also reducing the risk of polished rod damp or corrosion.

[0015] 2. Enhance reliability: when grounding operation is needed, the user can retract the insulating sleeve by simple action, expose the polished rod for connection, and under the action of the spring, only a small part of the polished rod is exposed for connection. This not only ensures the effectiveness of grounding, but also increases the safety of use and enhances the reliability of grounding connection.

[0016] 3. Prolong the service life: since the polished rod is well protected in the non-use state, physical damage or chemical corrosion caused by long-term exposure to harsh environments can be effectively prevented, thereby prolonging the overall service life of the grounding clamp.

[0017] In addition to the purposes, features and advantages described above, the utility model has other purposes, features and advantages. The utility model will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0024] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0025] The utility model provides a grounding wire clamp.

[0026] In the embodiment, with reference to Figures 1-4 The grounding wire clamp comprises a grounding ring 1 and a wire clamp body 2. One side of the grounding ring 1 is a rod part 2 connected with the wire clamp body. Insulating sleeves 3 are fixed on both sides of the grounding ring. A light rod 4 for grounding is left between the insulating sleeves 3. Sliding grooves 5 are arranged in the insulating sleeves on both sides of the light rod 4. Insulating sliding sleeves 6 are slidably connected in the sliding grooves 5. Springs 7 are arranged between the insulating sliding sleeves and the bottom of the sliding grooves. The springs have a spring force to push the insulating sliding sleeves out of the sliding grooves.

[0027] In the above technical solution, the insulating sleeves are arranged at both ends of the rod part of the grounding ring, and the insulating sliding sleeves and the springs are arranged in the insulating sleeves. When not in use, the insulating sliding sleeves completely cover the light rod under the pushing of the springs, effectively preventing the safety hazards caused by the direct exposure of the light rod, such as electric shock and corrosion of the light rod, and ensuring that the grounding ring can quickly and conveniently expose the light rod for grounding connection when in use. Moreover, when the light rod is connected and used with other components, the insulating sliding sleeves can also cover and wrap the excess light rod under the action of the springs.

[0028] One end of the spring is connected with the bottom wall of the sliding slot, and the other end is connected with the insulating sliding sleeve, the insulating sliding sleeve can be pushed out under the action of the spring force after being compressed back into the sliding slot.

[0029] Specifically, the grounding ring is a rectangular annular structure. The wire clamp body includes a mounting bottom plate 8, a wire clamp bottom plate 9, a wire clamp pressing plate 10, a bolt assembly one 11 for connecting the mounting bottom plate, the wire clamp bottom plate and the wire clamp pressing plate in series, and a bolt assembly two 12 for connecting the mounting bottom plate and the wire clamp bottom plate in series. The mounting bottom plate and the wire clamp bottom plate are provided with a connecting hole 13 for connecting with the rod part. The wire clamp bottom plate and the wire clamp pressing plate are both provided with a semi-ring clamping groove 14 for clamping the wire.

[0030] By arranging the mounting bottom plate, the wire clamp bottom plate, the wire clamp pressing plate and the corresponding bolt assemblies, the grounding wire clamp can be firmly fixed at the required position. The design of the semi-ring clamping groove ensures that the wire can be clamped stably, thereby ensuring the stability and reliability of the grounding connection.

[0031] Specifically, a plurality of convex patterns 15 are arranged on the inner wall of the semi-ring clamping groove.

[0032] The plurality of convex patterns on the inner wall of the semi-ring clamping groove increase the friction coefficient of the contact surface with the wire, further strengthen the clamping force of the wire, effectively prevent the wire from loosening due to vibration and the like during use, and improve the working stability of the grounding wire clamp.

[0033] Specifically, the connecting hole and the rod part are in polygonal structure.

[0034] The connecting hole and the rod part are in polygonal structure. The polygonal design instead of the common circular design can effectively prevent the rotation of the rod part in the connecting hole, ensure that the fixation between the grounding ring and the wire clamp body is more firm, and thereby improve the stability of the entire grounding wire clamp structure.

[0035] Specifically, the connecting hole and the rod part are in equilateral hexagonal structure.

[0036] The connecting hole and the rod part are in equilateral hexagonal structure. The equilateral hexagonal design not only inherits the advantages of the polygonal structure, i.e. preventing rotation, but also has better mechanical strength and torsion resistance, further optimizing the structural strength and durability of the grounding wire clamp, and being suitable for more severe working environments.

[0037] Note for all technical personnel: Although the utility model has been described according to the above specific implementation mode, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the patent protection range.
