A clamping and stabilizing clamp for parallel grooved wires of different diameters

Abstract

This utility model discloses a stable clamping clamp for wires of different diameters with parallel grooves. The clamp includes an upper clamping plate and a lower clamping plate. The lower clamping plate has first lower clamping grooves on both sides, and a raised lower clamping portion in the middle of the first lower clamping groove. The lower clamping portion has a second lower clamping groove. The upper clamping plate has a first upper clamping groove corresponding to the first lower clamping grooves, and a liftable pressure plate. Through the cooperation of the lower clamping portion and the pressure plate, the first lower clamping groove and the first upper clamping groove, and the second lower clamping groove and the second upper clamping groove, form a structure that accommodates the stranded wire and causes it to bend upwards. This increases the friction between the stranded wire and the clamping grooves. The bent stranded wire contacts both sides of the grooves, providing stable support and preventing clamp displacement. The raised inner wall of the clamping grooves enhances the contact area and friction, optimizing the structural design, reducing the risk of stranded wire detachment, and improving connection reliability and overall durability.

Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to a clamping clamp with stable clamping of different diameter parallel grooves. Background Technology

[0002] Parallel groove clamps are used to splice two conductors in power transmission lines. Existing clamps have insufficient clamping force, easily causing the stranded wires to detach. Over time, the stranded wires sway in the air, causing the clamping points to loosen, further increasing the risk of detachment. In addition, environmental factors such as temperature changes and mechanical vibrations may also affect clamping stability. Therefore, the applicant proposes an improvement scheme to enhance the clamping performance and improve connection reliability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the traditional parallel groove clamp design and provide a product with stable clamping.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A clamping clamp for stable clamping of different diameter parallel grooved wires includes an upper clamping plate and a lower clamping plate. The lower clamping plate has a first lower clamping groove on both sides. The middle area of ​​the first lower clamping groove has an upwardly protruding lower clamping part. The lower clamping part has a second lower clamping groove. The upper clamping plate has a first upper clamping groove corresponding to the first lower clamping groove. The upper clamping plate has a liftable pressure plate. The pressure plate has a second upper clamping groove corresponding to the second lower clamping groove. Fastening components are provided between the lower clamping plate and the upper clamping plate, and between the pressure plate and the lower clamping plate.

[0006] Preferably, the inner wall surfaces of the first lower clamping groove, the second lower clamping groove, the first upper clamping groove, and the second upper clamping groove are each provided with a plurality of equally spaced protrusions evenly distributed along their circumference, and the heads of the protrusions are provided with contact portions for contacting the surface of the stranded wire.

[0007] Preferably, the upper clamping plate is provided with a groove for the lifting and lowering of the pressure plate, and guide grooves are provided on both sides of the groove.

[0008] Preferably, the pressure plate is provided with guide blocks on both sides and is slidably disposed in the guide groove.

[0009] Preferably, the fastening assembly includes a bolt and a nut, the bolt being fitted with a spring washer and a flat washer in sequence, the flat washer abutting against one end of the upper clamping plate or pressure plate, and the nut being threadedly connected to the bolt and abutting against the other end of the lower clamping plate or pressure plate.

[0010] Preferably, both ends of the second upper clamping groove and both ends of the groove adjacent to the second upper clamping groove are provided with inclined transition portions.

[0012] Beneficial effects:

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the cooperation between the lower clamping part and the pressure plate to form a structure that accommodates the stranded wire and bends it upwards, thereby increasing the friction between the stranded wire and the clamping groove. The stranded wire in the bent state contacts both sides of the groove, and the groove provides stable support for the stranded wire, preventing the upper and lower clamping plates from shifting forward or backward due to external vibration or shaking. The protrusions on the inner wall of the clamping groove increase the contact area and friction with the wire surface, improving clamping stability. This optimized structural design effectively reduces the possibility of stranded wire falling off and improves connection reliability. At the same time, the bending structure helps to distribute the force, reduce local stress concentration, and enhance the overall structural durability. Attached Figure Description

[0024] Reference example Figures 1 to 4 A clamping clamp for stable clamping of different diameter parallel grooved wires includes an upper clamping plate 1 and a lower clamping plate 2. The lower clamping plate 2 has a first lower clamping groove 21 on both sides. The first lower clamping groove 21 has an upwardly protruding lower clamping part 22 in the middle area. The lower clamping part 22 has a second lower clamping groove 23. The upper clamping plate 1 has a first upper clamping groove 11 corresponding to the first lower clamping groove 21. The upper clamping plate 1 has a liftable pressure plate 3. The pressure plate 3 has a second upper clamping groove 4 corresponding to the second lower clamping groove 23. Fastening components 5 are provided between the lower clamping plate 2 and the upper clamping plate 1, and between the pressure plate 3 and the lower clamping plate 2.

[0025] By cooperating with the lower clamping part 22 and the pressure plate 3, the first lower clamping groove 21 and the first upper clamping groove 11, and the second lower clamping groove 23 and the second upper clamping groove 4 form a structure that accommodates the stranded wire and bends it upwards, thereby increasing the friction between the stranded wire and the clamping groove. The stranded wire in the bent state contacts both sides of the groove 12, and the groove 12 provides stable support for the stranded wire, preventing the upper and lower clamping plates 2 from shifting back and forth due to external vibration or shaking. The protrusions set on the inner wall of the clamping groove increase the contact area and friction with the wire surface, improving clamping stability. This optimized structural design effectively reduces the possibility of stranded wire falling off and improves connection reliability. At the same time, the bending structure helps to distribute the force, reduce local stress concentration, and enhance the overall structural durability.

[0026] It is worth mentioning that the inner wall surfaces of the first lower clamping groove 21, the second lower clamping groove 23, the first upper clamping groove 11, and the second upper clamping groove 4 are all provided with a number of equally spaced protrusions 6 evenly distributed along their circumference. The head of the protrusion 6 is provided with a contact part 61 for contacting the surface of the stranded wire. The protrusion 6 enhances the contact and friction with the surface of the conductor. The contact part 61 is embedded in the surface of the stranded wire to improve the clamping stability. This structural design prevents the upper and lower clamping plates from shifting due to wind vibration or high-altitude swaying, ensures that the clamping position is fixed, and improves the overall connection reliability and structural stability.

[0027] It is worth mentioning that the upper clamping plate 1 is provided with a groove 12 for the lifting and lowering of the pressure plate 3, and guide grooves 13 are provided on both sides of the groove 12. The guide grooves 13 cooperate with the guide block 31 to provide guidance for the lifting and lowering of the pressure plate 3.

[0028] It is worth mentioning that guide blocks 31 are provided on both sides of the pressure plate 3 and are slidably disposed in the guide groove 13;

[0029] It is worth mentioning that the fastening assembly 5 includes a bolt 51 and a nut 52. The bolt 51 is fitted with a spring washer 53 and a flat washer 54 in sequence. The flat washer 54 abuts against one end of the upper clamping plate 1 or the pressure plate 3. The nut 52 is threaded to the bolt 51 and abuts against the other end of the lower clamping plate 2 or the pressure plate 3. The spring washer provides preload and cushioning, which helps to maintain a stable clamping force.

[0030] It is worth mentioning that both ends of the second upper wire clamping groove 4 and both ends of the groove 12 adjacent to the second upper wire clamping groove 4 are provided with inclined transition parts 7. The transition parts 7 prevent the stranded wire from being worn at the bend, and improve the clamping effect and service life.

[0031] It is worth mentioning that the cross-sectional shapes of the first lower clamping groove 21, the second lower clamping groove 23, the first upper clamping groove 11, and the second upper clamping groove 4 are adapted to the outer surface shape of the stranded wire.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
