Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of copper wire cold connection, in particular to a single copper wire cold connection device. Background Art
[0002] Copper wire cold joining pliers are a tool used for cold joining copper wires. The cold joining principle includes passing the metal wire through a special die, and under a certain extrusion, the pure metal lattices therein are intermixed and pressed together to achieve the connection of the molecular atomic structure. In actual operation, the contact surface area of the connection will expand, causing the original oxide protective film on the welding surface that hinders welding to rupture, and the high-voltage load makes the exposed pure metal material in close contact, resulting in a bond between atoms, and welding can be achieved by continuing to apply force.
[0003] Cold joining does not use welding or other heat treatment methods. The copper wire cold joining pliers are usually composed of two clamps for clamping the copper wire. There are some grooves or notches inside the clamps to increase the friction coefficient and increase the clamping and fixing effect.
[0004] In the prior art, when workers use cold-joining pliers to cold-join two groups of single copper wires, due to the small diameter of the single copper wire, it is difficult for the workers to observe the state of the copper wire in the mold during the cold-joining process, which makes it difficult for the workers to promptly determine whether the cold-joining of the two groups of single copper wires is completed, resulting in low production efficiency. In particular, when bulges appear on the copper wire during cold-joining and need to be polished and removed, it is rather troublesome to find the position of the bulge after the copper wire is removed, which is not conducive to improving production efficiency and product yield. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a single copper wire cold connection device to solve the technical problem that the copper wire cold connection technology in the prior art is not conducive to improving production efficiency and product yield.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a single copper wire cold connection device, comprising a main body, a cold connection mold matched with the main body is arranged inside the main body, a fixed handle is fixed on one side of the main body, a flip plate is rotatably connected to the top of the fixed handle, a fixed ring is rotatably connected to the top end of the flip plate, a magnifying glass is fixed inside the fixed ring, and the magnifying glass is located just above the center of the cold connection mold, a clamping handle matched with the fixed handle is rotatably connected to the bottom of the main body, and the clamping handle rotates relative to the fixed handle;
[0007] The fixed handle and the flip plate are rotationally connected via a first hinge seat, the flip plate and the fixed ring are rotationally connected via a second hinge seat, and both the first hinge seat and the second hinge seat are configured with a damping shaft so that the first hinge seat and the second hinge seat play a positioning role.
[0008] By adopting the above technical scheme, the staff inserts two groups of single copper wires from both ends of the cold-joining mold at the same time, so that the end faces of the two groups of single copper wires are located at the center of the cold-joining mold and close to each other. As the staff manually turns the clamping handle, the cold-joining mold performs the cold-joining operation on the two groups of single copper wires. At the same time, the staff places a magnifying glass directly above the cold-joining mold, and then the staff can more easily observe the cold-joining process of the two groups of single copper wires at the center of the cold-joining mold through the magnifying glass, and can better observe the cold-joining conditions of the single copper wires, which is more convenient to use.
[0009] The utility model is further configured that both ends of the main body are provided with openings that match with the cold connection mold.
[0010] By adopting the above technical solution, the opening serves to insert two groups of single copper wires into the cold connection mold, which makes the cold connection operation of the copper wires more convenient.
[0011] To sum up, the utility model mainly has the following beneficial effects: the staff of the utility model inserts two groups of single copper wires from both ends of the cold-joining mold at the same time, so that the end faces of the two groups of single copper wires are located at the center of the cold-joining mold and close to each other. As the staff manually rotates the clamping handle, the cold-joining mold performs cold-joining operations on the two groups of single copper wires. At the same time, the staff places a magnifying glass directly above the cold-joining mold, and then the staff can more easily observe the cold-joining process of the two groups of single copper wires at the center of the cold-joining mold through the magnifying glass, and can better observe the cold-joining conditions of the single copper wires. It is relatively convenient to use and is easy to promptly discover defects such as bulging of the copper wire, so that the bulging defects can be accurately polished and removed later, providing convenience for improving production efficiency and product yield.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the single copper wire cold connection device provided by the utility model includes a main body 1, a cold connection mold 2 matched with the main body 1 is arranged inside the main body 1, a fixed handle 3 is fixed on one side of the main body 1, the top of the fixed handle 3 is rotatably connected to a flip plate 5, the top end of the flip plate 5 is rotatably connected to a fixed ring 6, a magnifying glass 7 is fixed inside the fixed ring 6, and the magnifying glass 7 is located directly above the center of the cold connection mold 2. The staff places the magnifying glass 7 directly above the cold connection mold 2, and then the staff can more easily observe the cold connection process of the two groups of single copper wires at the center of the cold connection mold 2 through the magnifying glass 7, and can better observe the cold connection situation of the single copper wire. It is more convenient to use and is easy to timely discover defects such as bulging of the copper wire, so as to accurately grind and remove the bulging defects later, which provides convenience for improving production efficiency and product yield.
[0021] A clamping handle 4 that matches the fixed handle 3 is rotatably connected to the bottom of the main body 1 , and the clamping handle 4 can be clamped and moved relative to the fixed handle 3 .
[0022] The fixed handle 3 and the flip plate 5 are rotationally connected via the first hinge seat 8, and the flip plate 5 and the fixed ring 6 are rotationally connected via the second hinge seat 9. Both the first hinge seat 8 and the second hinge seat 9 are configured with a damping shaft, so that the first hinge seat 8 and the second hinge seat 9 play a positioning role.
[0023] See also Figure 1 Both ends of the main body 1 are provided with openings that match the cold connection mold 2. The utility model sets the above structure, wherein the openings play a role in loading two groups of single copper wires into the cold connection mold 2, which makes the cold connection operation of the copper wires more convenient.
[0024] The working principle of the utility model is as follows: when in use, the cold connection mold 2 is first installed inside the main body 1, wherein the cold connection mold 2 can be replaced with different specifications according to the cold connection operation of copper wires with different diameters.
[0025] The staff inserts two groups of single copper wires into the cold-joining mold 2 from both ends at the same time, so that the end faces of the two groups of single copper wires are located at the center of the cold-joining mold 2 and close to each other. As the staff manually pre-tightens the clamping handle 4, the cold-joining mold 2 performs the cold-joining operation on the two groups of single copper wires.
[0026] At the same time, the staff places the magnifying glass 7 directly above the cold-joining mold 2, and then the staff can more easily observe the cold-joining process of the two groups of single copper wires at the center of the cold-joining mold 2 through the magnifying glass 7, and can better observe the cold-joining situation of the single copper wire. It is more convenient to use, and can conveniently observe and adjust the lead-out length of the copper wire end face to ensure the effectiveness of the cold joint.
[0027] Furthermore, the magnifying glass 7 is movably connected through the first hinge seat 8, the flip plate 5, the second hinge seat 9 and the fixed handle 3. That is to say, during the cold connection operation, the staff can manually flip the magnifying glass 7 to the center position of the cold connection mold 2 to observe it. When not in use or loading copper wire, the magnifying glass 7 can be flipped in the opposite direction to the top of the fixed handle 3 to avoid blocking the copper wire and avoiding collision between foreign objects and the magnifying glass when not in use, thereby preventing the magnifying glass 7 from being damaged. This not only makes the overall storage easier, but also improves the service life of the magnifying glass 7 to a certain extent.
[0028] The single copper wire cold joining device of the utility model is integrated with a magnifying glass, which is convenient for observing the loading state, cold joining state, bulging defects, etc. of the copper wire through the magnifying glass during the cold joining operation, and problems in the cold joining can be discovered in time for timely regulation, which can effectively facilitate the improvement of the production efficiency and product yield of the copper wire cold joining.
