Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, specifically to a wedge-shaped wire clamp. Background Technology

[0002] In many fields such as power and communications, wedge clamps are widely used as key components for fixing and connecting cables due to their simple structure and convenient installation. Traditional wedge clamps typically consist of a clamp base and a wedge-shaped clamping block. By placing the cable in the groove of the wedge-shaped clamping block, the cable is clamped and fixed by the cooperation between the wedge-shaped clamping block and the wedge-shaped through hole of the clamp base.

[0003] However, existing wedge clamps have several problems in practical use. Firstly, their cable tray design is flawed, resulting in limited contact area between the cable and the tray. This makes the cable prone to loosening and slippage during long-term use, affecting the stability and reliability of the connection. Secondly, the smooth inner surface of the cable tray lacks effective friction when clamping the cable, making it difficult to ensure a secure fixation. Furthermore, repeated disassembly and reassembly can cause wear and tear on the cable, reducing its lifespan. In addition, traditional wedge clamps offer insufficient cable restraint and protection, failing to meet the higher requirements for cable connections under certain special operating conditions. Therefore, it is urgent to improve and optimize the existing wedge clamp structure to enhance its performance and usability. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a wedge-shaped wire clamp.

[0005] The technical solution adopted by this utility model is: a wedge-shaped wire clamp, including a clamp base and a wedge-shaped clamp block. The clamp base is provided with a wedge-shaped through hole adapted to the wedge-shaped clamp block. The wedge-shaped clamp block is inserted into the wedge-shaped through hole. A wire groove is provided along the outer wall of the outer ring of the wedge-shaped clamp block. The wire groove includes an arc bottom and vertical surfaces provided on both sides of the opening of the arc bottom. A fitting groove is provided on the vertical surface. An elastic retaining ring is installed on the fitting groove. The surface of the elastic retaining ring is provided with multiple rings of friction-increasing protrusions. The outermost elastic retaining ring is provided with a ring of limiting protrusions. The height of the limiting protrusions is higher than that of the friction-increasing protrusions.

[0006] Furthermore, the height of the limiting protrusion is 2-5mm higher than that of the friction-increasing protrusion.

[0007] Furthermore, the inner side of the limiting protrusion has an arc-shaped surface.

[0008] Furthermore, the fitting groove has a "T" shaped structure, and the elastic retaining ring is provided with a "T" shaped connecting end that connects to the fitting groove.

[0009] Furthermore, the wedge-shaped clamping block has several protruding strips evenly spaced on the inner wall of the groove at the arc end.

[0010] Furthermore, the inner wall of the convex strip is provided with a concave surface that is adapted to the curvature of the groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. The cable tray adopts a structure design with a rounded bottom and a vertical surface. Compared with traditional cable trays, it can increase the contact area with the cable, making the cable more evenly stressed in the wedge-shaped clamp, effectively reducing the risk of cable loosening and slippage, and significantly improving the stability and reliability of the connection.

[0013] Second, the fitting groove on the vertical surface is equipped with an elastic retaining ring. The multiple rings of friction-increasing serrations on the surface of the elastic retaining ring greatly increase the friction between the retaining ring and the cable and the wrapping effect on the cable, further ensuring that the cable is firmly fixed in the groove. Even during multiple disassembly and assembly processes, it can reduce the wear of the cable caused by friction and extend the service life of the cable.

[0014] Third, the limiting teeth set in the outermost elastic retaining ring are higher than the friction-increasing teeth, which can play a stronger limiting and wrapping role for the cable, preventing the cable from shifting under large external forces or special working conditions, providing more reliable protection for the cable, meeting the higher requirements for cable connection under special working conditions, and effectively expanding the application scenarios of wedge clamps.

[0015] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides a wedge-shaped wire clamp.

[0028] In this embodiment, refer to Figures 1-7 The wedge-shaped wire clamp includes a clamp base 1 and a wedge-shaped clamp block 2. The clamp base is provided with a wedge-shaped through hole 3 that is adapted to the wedge-shaped clamp block. The wedge-shaped clamp block is inserted into the wedge-shaped through hole 3. A wire groove 4 is provided along the outer wall of the outer ring of the wedge-shaped clamp block. The wire groove 4 includes an arc-shaped bottom 5 and vertical surfaces 6 provided on both sides of the opening of the arc-shaped bottom. A fitting groove 7 is provided on the vertical surface 6. An elastic retaining ring 8 is installed on the fitting groove. The surface of the elastic retaining ring 8 is provided with multiple rings of friction-increasing protrusions 9, and the outermost elastic retaining ring is provided with a ring of limiting protrusions 10. The height of the limiting protrusions is higher than that of the friction-increasing protrusions.

[0029] In the above technical solution, the contact area between the cable and the cable tray is increased by designing the cable tray as a combination of a rounded bottom and a vertical surface. An elastic retaining ring is installed in a fitting groove on the vertical surface. The friction-increasing protrusions on the surface of the elastic retaining ring increase the friction with the cable, while the outermost limiting protrusions, with their greater height, limit the cable's position. This ensures that the cable is evenly stressed within the wedge-shaped clamp, reducing the risk of loosening or slippage. The friction-increasing protrusions ensure the cable is firmly fixed, reducing wear during assembly and disassembly. The limiting protrusions prevent the cable from shifting under external forces, meeting the needs of special working conditions and expanding application scenarios.

[0030] Specifically, the height of the limiting protrusion is 2-5mm higher than that of the friction-increasing protrusion.

[0031] In this embodiment, the height of the limiting protrusion is set 2-5mm higher than that of the friction-increasing protrusion to ensure that the limiting protrusion can effectively limit the movement of the cable. This ensures the cable is wrapped and limited.

[0032] Specifically, the inner side of the limiting protrusion has an arc-shaped surface 11.

[0033] Specifically, the fitting groove has a "T" shaped structure, and the elastic retaining ring is provided with a "T" shaped connecting end that connects to the fitting groove.

[0034] In this embodiment, the fitting groove adopts a "T"-shaped structure, and the elastic retaining ring is provided with a "T"-shaped connecting end 12. Utilizing the locking characteristic of the "T"-shaped structure, the elastic retaining ring can be securely installed in the fitting groove, preventing it from falling off or shifting during use, and ensuring that it continues to play its role in increasing friction and limiting movement. It also facilitates disassembly and assembly.

[0035] Specifically, the wedge-shaped clamping block has several protrusions 13 evenly spaced on the inner wall of the groove at the arc end.

[0036] In this embodiment, several protrusions are evenly spaced on the inner wall of the wire groove at the arc end of the wedge-shaped clamp. By increasing the roughness of the inner wall of the wire groove and the protruding structure, the friction between the cable and the inner wall of the wire groove is further increased, enhancing the fixing effect of the cable in the wire groove at the arc end, preventing the cable from sliding or shifting at this part, and working together with other structures to improve the overall fixing performance of the wedge-shaped clamp on the cable and improve the reliability of the connection.

[0037] Specifically, the inner wall of the convex strip is provided with a concave surface 14 that is adapted to the curvature of the groove.

[0038] In this embodiment, the inner wall of the convex strip is provided with a concave surface that adapts to the curvature of the wire groove. The concave surface can better fit the surface of the cable and the wire groove, making the contact between the convex strip and the cable tighter, increasing the contact area, and further enhancing the friction and support.

[0039] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
