Description

Technical Field

[0001] The utility model relates to the technical field of copper bars, and more specifically, to a high-resistance copper bar. Background Art

[0002] A copper bar, also known as a copper busbar or copper bus, is a flat plate-shaped conductor made of copper, which plays the role of transporting current and connecting electrical equipment in a circuit.

[0003] When connecting an electric wire to a copper bar, it is necessary to first loosen the bolt, then wind the wire core of the electric wire around the bolt, and then tighten the screw. Soft copper wires cannot be directly fixed by screws. It is necessary to divide the soft copper wire into two strands and wind them around the bolt or terminal post. After combining and tightening, the electric wire is fixed to the copper bar through the bolt. Hard copper wires also need to bend the hard wire core into a hook shape or a circular ring, and then fix the wire core by tightening the bolt. This is not convenient enough in the actual installation process and affects the installation efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a high-resistance copper bar to improve the working efficiency during the installation of copper wires and improve the convenience of the copper bar.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A high-resistance copper bar, including a plate-shaped conductive body, installation holes and a plurality of locking bolt holes are opened on the conductive body, a fixing member is fixedly connected to the end surface of the conductive body, the fixing member is circular ring-shaped, a placing groove is opened on the top surface of the fixing member, an outlet and an inlet are opened on the side wall of the fixing member, the outlet and the inlet communicate with the placing groove, a pressing member is arranged on the top surface of the fixing member, a part of the pressing member extends into the placing groove, a fixing bolt is slidably connected to the pressing member, and the fixing bolt is in threaded connection with the locking bolt hole.

[0007] The present utility model is further arranged as: The pressing member includes a gasket I at the top and a pressing ring fixedly connected to the bottom surface of the gasket I, the pressing ring extends into the placing groove, and an opening for the fixing bolt to pass through is opened on the end surface of the gasket I.

[0008] The present utility model is further arranged as: An elastic member is fixedly connected between the gasket I and the conductive body, and the elastic member is a compression spring.

[0009] The present utility model is further arranged as: Both the outlet and the inlet are provided with two, a baffle is rotatably connected to the outlet, and a fixing pull ring is fixedly connected to the end surface of adjacent baffles.

[0010] The present utility model is further configured such that the bottom of the placement groove is provided with rounded corners.

[0011] In summary, the present utility model has the following beneficial effects: After the soft copper wire is split into strands, it can extend into the fixing member through the inlet, pass through the two outlets, and then the two soft copper wires are twisted tightly. Then, the fixing bolt is tightened to press the pressing member against the copper wire, and the copper wire is not easily scattered, improving the installation efficiency of the copper wire and ensuring that the copper bar has good electrical conductivity, stability, and convenience.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] A high-resistance copper bar, such as Figure 1 - Figure 5As shown in the figure, it includes a plate-shaped conductive body 1. An installation hole 101 and a number of locking bolt holes 102 are provided on the conductive body 1. A fixing member 3 is fixedly connected to the end surface of the conductive body 1. The fixing member 3 is annular. A placement groove is provided on the top surface of the fixing member 3. An outlet 302 and an inlet 301 are provided on the side wall of the fixing member 3. The outlet 302 and the inlet 301 communicate with the placement groove 303. A pressing member 5 is provided on the top surface of the fixing member 3. The pressing member 5 partially extends into the placement groove 303. A fixing bolt 2 is slidably connected to the pressing member 5. The fixing bolt 2 is threadedly connected to the locking bolt hole 102. The copper wire can enter the fixing member 3 through the inlet 301. According to the different hardness of the copper wire, it can be selected whether the copper wire passes through the outlet 302, and the copper wire in the fixing member 3 is pressed by the pressing member 5, reducing the occurrence of copper wire falling off and shaking, and improving the installation efficiency.

[0020] As Figure 1 - Figure 5 As shown in the figure, two outlets 302 and two inlets 301 are respectively provided on the fixing member 3. The setting of the two outlets 302 and the two inlets 301 facilitates the soft copper wire to be split into strands and then enter the interior of the fixing member 3 through the inlet 301, and then pass through the outlet 302 and out of the fixing member 3. A baffle 6 is rotatably connected to the outlet 302. The two baffles 6 can block or open the outlet 302. When fixing the hard copper wire, the baffle 6 can be used to block the outlet 302 to prevent the hard copper wire from passing through the outlet 302, so that it can better slide to another inlet 301 inside the fixing member 3 and then be pressed and fixed. When fixing the soft copper wire, the baffle 6 can be pushed towards the interior of the fixing member 3 to open the outlet 302, so that two separate cavities are formed inside the fixing member 3, and two strands of soft copper wire can respectively pass through the two outlets 302, and the baffle 6 plays the role of guiding the copper wire to pass through the outlet 302. Preferably, a fixing pull ring 7 is fixedly connected to two adjacent baffles 6. The fixing pull ring 7 is located outside the fixing member 3. The fixing pull ring 7 can be made of copper wire. Using the characteristics of the plastic deformation of the material, it is ensured that the baffle 6 can stably open or block the outlet 302.

[0021] As Figure 1 - Figure 5As shown, the pressing member 5 includes a first gasket 501 at its top and a pressing ring 502 fixedly connected to the bottom surface of the first gasket 501. The pressing ring 502 extends into the placement groove 303, and the pressing ring 502 is a notched ring with its notch position close to the outlet 302, facilitating the soft copper wire to pass through the outlet 302 and extend out of the fixing member 3. The first gasket 501 is provided with an opening for the fixing bolt 2 to pass through. When the pressing member is displaced towards the fixing member 3 by tightening the fixing bolt 2, the pressing ring 502 gradually extends into the placement groove 303 and squeezes the copper wire inside it, realizing the fixation of the copper wire. An elastic member 8 is fixedly connected between the first gasket 501 and the conductive body 1. The elastic member 8 is set as a compression spring. The setting of the compression spring can make the pressing member 5 automatically move away from the fixing member 3 when the fixing bolt 2 is loosened, and the pressing ring 502 gradually moves away from the placement groove 303, facilitating the removal of the copper wire in the placement groove 303, which is more convenient. Preferably, the bottom of the placement groove 303 is provided with a rounded corner 9, and the bottom of the rounded corner 9 facilitates the sliding of the copper wire in the placement groove 303, improving the installation efficiency.

[0022] As Figure 1 - Figure 5 shown, a second gasket 4 is further provided above the first gasket 501. The setting of the second gasket 4 facilitates that the fixing bolt 2 is not easily affected when rotating, reducing the occurrence of rotational displacement of the pressing member 5 during the rotation of the fixing bolt 2 and improving the stability during installation. The fixing member 3, the first gasket 501, the second gasket 4, the pressing ring 502, and the locking bolt hole 102 are coaxially arranged to ensure the stability when fixing the copper wire through the fixing bolt 2 and improve the installation efficiency. Moreover, the surfaces of the conductive body 1, the fixing member 3, the pressing member 5, and the second gasket 4 are all galvanized, effectively preventing copper from reacting and corroding with the external environment, greatly enhancing the corrosion resistance of the copper bar and extending its service life. At the same time, it can improve the conductivity of the copper bar. The fixing member 3, the pressing member 5, the elastic member 8, and the retaining piece 6 are all made of conductive materials to ensure the overall conductive effect of the copper bar.

[0023] Working principle: When installing soft copper wire or hard copper wire using this highly resistant copper bar, the conductive body 1 can be fixed in the electrical box through the installation hole 101 first. When installing hard copper wire, after cutting off the insulator outside the copper wire, insert the hard copper wire into the inlet 301, and pull the fixing ring 7 to rotate the baffle 6 to a state covering the outlet 302. Push the hard copper wire to slide in the placement groove 303 and deform it. Then, turn the fixing bolt 2. During the process of gradually tightening the fixing bolt 2 with the locking fixing bolt 2 hole, the pressing ring 502 is gradually squeezed towards the bottom of the placement groove 303 through the first gasket 501 and the second gasket 4 to fix the hard copper wire. When installing soft copper wire, first divide the soft copper wire into two strands and twist the two strands of copper wire to make its structure more stable and not easy to come loose. Insert the two strands of soft copper wire into the two inlets 301, and push the fixing ring 7 to make the baffle 6 extend into the placement groove 303. Continuously push the two strands of soft copper wire to pass through the two outlets 302 and out of the fixing part 3. Then, combine the two strands of soft copper wire and twist them together. Then, turn the fixing bolt 2. During the process of gradually tightening the fixing bolt 2 with the locking fixing bolt 2 hole, the pressing ring 502 is gradually squeezed towards the bottom of the placement groove 303 through the first gasket 501 and the second gasket 4 to fix the soft copper wire.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
