Description

Technical Field

[0001] The present invention relates to the technical field of line fittings, and in particular to a copper-aluminum wire clamp with a simple multi-wire diameter function and a manufacturing method thereof. Background Art

[0002] Line fittings can be roughly divided into suspension fittings, anchoring fittings, connecting fittings, splicing fittings, and protective fittings, etc. As a kind of line fitting, a wire clamp is mainly used in overhead lines to support, fix and splice bare conductors, conductors and insulators into strings, and can also be used to protect conductors and insulators. The patent with application number CN201820132571.4 discloses a portable short-circuit grounding wire clamp, which includes an insulating handle, a U-shaped wire clamp body, and a contact piece. One side of the U-shaped wire clamp body is provided with an internal threaded hole. One end of the insulating handle passes through the internal threaded hole of the U-shaped wire clamp body and presses against the contact piece to be pressed against the inner side wall of the U-shaped wire clamp body; several wiring holes are provided on the U-shaped wire clamp body; the insulating handle is an insulating handle with an external thread. However, the top and bottom surfaces of the contact piece are smooth, which is rather troublesome and not easy to operate during the wiring process. During use, the contact piece is easily detached from the U-shaped wire clamp body under the influence of force. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the above-mentioned prior art, and provides a copper-aluminum wire clamp with a simple multi-wire diameter function and a manufacturing method thereof, which can improve stability, ensure effective clamping of the cable, is simple to operate and easy to use, saves manpower and time, and improves work efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problems: This copper-aluminum wire clamp with a simple multi-wire diameter function includes a tightening frame and a grounding ring. The tightening frame is of a C-shaped structure, with an opening on the side of the tightening frame, a V-shaped groove inside the tightening frame, a first threaded hole opened at the top of the tightening frame, a threaded rod threadedly connected inside the first threaded hole, a convex column fixedly connected to the bottom of the threaded rod, a clamping block inside the tightening frame, a T-shaped groove opened at the top of the clamping block, the convex column is inside the T-shaped groove, a cable is inside the V-shaped groove, the clamping block abuts against the side surface of the cable, an arc groove is opened at the bottom of the clamping block, the side surface of the cable reaches inside the arc groove, the grounding ring is installed on the side of the tightening frame, a connecting ring is fixedly connected to the top of the threaded rod. When the cable is placed into the V-shaped groove, rotating the connecting ring drives the threaded rod to rotate synchronously. The convex column rotates in the T-shaped groove of the clamping block, and the clamping block moves and reaches the V-shaped groove. The clamping block abuts against the side surface of the cable, and the side surface of the cable reaches inside the arc groove. Tighten the connecting ring and the threaded rod, and the cable is installed, set and fixed inside the tightening frame. Then, according to needs, other lines are connected to the grounding ring, which improves stability, ensures effective clamping of the cable, is simple to operate and easy to use, saves manpower and time, and improves work efficiency.

[0005] For further improvement, the first threaded hole is located at the center of the top of the tightening frame, and the threaded rod reaches the center inside the tightening frame, so that the acting force is concentrated to avoid force deviation and improve the overall strength.

[0006] For further improvement, an arc surface is provided at the bottom of the tightening frame, and rounded corners are provided on the sides of the tightening frame to reduce sharp right-angled edges and improve the overall smoothness.

[0007] For further improvement, a retaining bar is fixedly connected to the top of the tightening frame, and a chamfer is provided at the top of the opening. The retaining bar forms an effective partition to reduce the influence on the threaded rod, and the chamfer is provided to reduce obstruction and facilitate the cable to quickly enter the inside of the tightening frame.

[0008] For further improvement, mounting holes are provided on the sides of the tightening frame. The grounding ring is of a C-shaped structure and is inserted into the mounting holes. The grounding ring is installed and removed in the mounting holes of the tightening frame, and the loading and unloading are easy and convenient for replacement, further improving the flexibility.

[0009] For further improvement, fixing screws are provided on the sides of the tightening frame, and second threaded holes are provided on the sides of the tightening frame. The second threaded holes communicate with the mounting holes. The fixing screws are threadedly connected to the second threaded holes. The fixing screws reach the inside of the mounting holes and abut against the side surface of the grounding ring. There are two fixing screws and two second threaded holes respectively. The two fixing screws simultaneously abut against the side surface of the grounding ring, and the grounding ring is effectively fixed in the mounting holes to prevent the grounding ring from moving and detaching.

[0010] For further improvement, internal hexagon screws are provided inside the T-shaped groove. There are two internal hexagon screws, which are distributed on the left and right sides of the convex post. The two internal hexagon screws further limit the convex post, and the convex post always remains at the center position inside the T-shaped groove, making it difficult for the clamping block to detach from the bottom of the threaded rod.

[0011] For further improvement, threaded grooves are provided inside the T-shaped groove. The internal hexagon screws are threadedly connected to the threaded grooves. There are two threaded grooves. By screwing out the internal hexagon screws from the threaded grooves, the internal hexagon screws are disengaged from the threaded grooves and the T-shaped groove, and the whole clamping block is moved to achieve the removal of the clamping block, which is convenient for replacing and adjusting the clamping block.

[0012] A copper-aluminum wire clamp with a simple multi-wire diameter function and its manufacturing method include the following steps:

[0013] S1. Casting and forming: The tightening frame, threaded rod, and clamping block are made of the same metal material. The raw material of the metal material undergoes processes such as raw material selection, high-temperature melting, and casting and forming. The blank parts of the tightening frame, threaded rod, and clamping block are respectively manufactured in different molds. While the blank part of the tightening frame shows the main structure, structures such as openings, V-shaped grooves, arc surfaces, fillets, retaining bars, chamfers, and mounting holes are also generated. While the blank part of the threaded rod shows the main structure, structures such as connecting rings and protruding columns are also generated. While the blank part of the clamping block shows the main structure, structures such as T-shaped grooves and arc grooves are also generated;

[0014] S2. Setting holes and threads: The blank part of the tightening frame is fixed in a special device. First, a hole is drilled at the center of the top of the tightening frame, and then tapping is performed in the drilled hole to generate the first threaded hole. The blank part of the tightening frame is fixed in another device. Two holes are drilled on the side of the tightening frame, and the two holes are connected to the mounting holes. Then, tapping is performed in the two holes to generate two second threaded holes. The blank part of the threaded rod is fixed on the chuck of the lathe, and the surface thread is processed. The blank part of the clamping block is fixed in a special device. Two grooves are drilled in the T-shaped groove, and then tapping is performed in the drilled grooves to generate two threaded grooves;

[0015] S3. Bending and shaping: Cut and intercept the raw material for making the grounding ring. Place the strip-shaped raw material on the bending machine, and fold the four corners of the strip-shaped raw material as required to generate a C-shaped grounding ring with non-connected ends;

[0016] S4. Surface treatment: Use grinding tools to respectively grind and process the tightening frame, threaded rod, clamping block, and grounding ring, smooth and remove excess burrs, and grind the sharp right-angle edges smoothly. A large number of tightening frames, threaded rods, clamping blocks, and grounding rings are classified and cleaned, left to dry and then stored statically. Spray protective paint as needed.

[0017] The beneficial effects of the present invention are:

[0018] 1. By placing the cable into the V-shaped groove, rotating the connecting ring drives the threaded rod to rotate synchronously. The protruding column rotates in the T-shaped groove of the clamping block, and the clamping block moves and reaches the V-shaped groove. The clamping block abuts against the side surface of the cable, and the side surface of the cable reaches the arc groove. Tighten the connecting ring and the threaded rod, and the cable is installed and fixed in the tightening frame. Connect other lines to the grounding ring as needed to improve stability and ensure that the cable is effectively clamped. The operation is simple and easy to use, saving manpower and time and improving work efficiency.

[0019] 2. By installing and removing the grounding ring in the mounting hole of the tightening frame, the installation and disassembly are easy and convenient for replacement, further improving flexibility. The two fixing screws simultaneously abut against the side surface of the grounding ring, and the grounding ring is effectively fixed in the mounting hole, preventing the grounding ring from moving and detaching.

[0020] 3. Further restrict the convex post through two hexagon socket head cap screws. The convex post always remains at the central position inside the T-shaped groove, and it is difficult for the clamping block to break away from the bottom of the threaded rod. Unscrew the hexagon socket head cap screws in the threaded groove. The hexagon socket head cap screws disengage from the threaded groove and the T-shaped groove. Move the entire clamping block to achieve the removal of the clamping block, which facilitates the replacement and adjustment of the clamping block. Brief Description of the Drawings
