Description

Technical Field

[0001] This utility model relates to the field of busbar connection technology, and more specifically to a power busbar connection device. Background Technology

[0002] Busbars refer to the copper or aluminum busbars that connect the main switch in the electrical cabinet to the switches in each branch circuit in a power supply system. Their main function is to serve as conductors. Busbars in different electrical cabinets need to be connected to each other to conduct electricity normally.

[0003] Most existing busbars are connected by bolts. During the connection, workers need to insert the bolts one by one between the busbars and then tighten them one by one with a wrench. When there are many busbars to be connected, a large number of bolts need to be tightened repeatedly, which is time-consuming and labor-intensive. Therefore, it is urgent to design a power busbar connection device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power busbar connection device to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a power busbar connection device, including a first connection component, a second connection component, and a locking component. The second connection component is slidably inserted into a plurality of busbars, the first connection component is slidably sleeved on the second connection component, and the locking component is disposed on one side of the second connection component. The first connection component and the locking component are adapted to each other.

[0006] The first connecting assembly includes a pressure plate, two rotating rods, and two arc-shaped rods. The two rotating rods are rotatably installed inside the pressure plate, and the two arc-shaped rods are fixedly installed on the two rotating rods respectively. The second connecting assembly includes an X-shaped plate and four connecting rods. The four connecting rods are fixedly installed on one side of the X-shaped plate, and the pressure plate is slidably sleeved between the four connecting rods. The locking assembly includes a screw and a sliding ring. The screw is rotatably installed inside the X-shaped plate, and the sliding ring is slidably sleeved on the screw through a thread. The arc-shaped rods are adapted to the sliding ring.

[0007] Furthermore, the first connecting assembly also includes four first gaskets, all of which are fixedly installed on the side of the pressure plate near the busbar. The second connecting assembly also includes four second gaskets, all of which are fixedly installed on the side of the X-shaped plate near the busbar.

[0008] Furthermore, the locking assembly also includes a hexagonal block, which is fixedly mounted on one side of the screw.

[0009] Furthermore, the locking assembly also includes four insert rods, all of which are fixedly installed on one side of the sliding ring. Two through holes are opened on one side of each of the two arc-shaped rods, and the insert rods are adapted to the through holes.

[0010] Furthermore, the second connecting assembly also includes two limiting rods, both of which are fixedly installed on one side of the X-shaped plate. The outer circumferential wall of the sliding ring has two limiting grooves, which are adapted to the limiting rods.

[0011] Furthermore, the locking assembly also includes a ratchet, ratchet teeth, a paddle, and two springs. The ratchet is fixedly sleeved on the screw. A mounting hole is provided on one side of the X-shaped plate. The screw is rotatably installed in the mounting hole. A circular groove is provided on the inner wall of the mounting hole. The ratchet is rotatably installed in the circular groove. The ratchet teeth are slidably inserted into the X-shaped plate and mesh with the ratchet. The paddle is fixedly installed at one end of the ratchet teeth. Both springs are fixedly installed between the paddle and the X-shaped plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention, through the provision of a first connecting component, a second connecting component, and a locking component, simplifies the connection process when multiple busbars need to be connected. First, four connecting rods are inserted into the overlapping busbars. Then, a pressure plate is fitted between the four connecting rods, and two rotating rods are rotated to align the two arc-shaped rods parallel to the sliding ring. At this point, a wrench is used to rotate the hexagonal block and the screw, causing the sliding ring to slide towards the two arc-shaped rods. This, in turn, causes the insert rod to insert into the through hole on the arc-shaped rod. As the sliding ring continues to slide, it exerts a thrust on the arc-shaped rod, which in turn exerts a thrust on the two rotating rods and the pressure plate, ensuring tight contact between the pressure plate and the busbar. Simultaneously, the sliding ring also exerts a thrust on the screw, which in turn exerts a thrust on the X-shaped plate, ensuring tight contact between the X-shaped plate and the busbar. This results in a tight connection of the busbars. Compared to existing installation methods, workers only need to install the X-shaped plate and the pressure plate, and then use a wrench to rotate the hexagonal block to connect the busbars, simplifying the installation process.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 6 The present invention will be further described below.

[0023] A power busbar connection device includes a first connecting component 2, a second connecting component 3, and a locking component 4. The second connecting component 3 is slidably inserted into a plurality of busbars 1. The first connecting component 2 is slidably sleeved on the second connecting component 3. The locking component 4 is disposed on one side of the second connecting component 3. The first connecting component 2 and the locking component 4 are adapted to each other.

[0024] The first connecting assembly 2 includes a pressure plate 201, two rotating rods 203, and two arc-shaped rods 204. The two rotating rods 203 are rotatably installed inside the pressure plate 201, and the two arc-shaped rods 204 are respectively fixedly installed on the two rotating rods 203. The second connecting assembly 3 includes an X-shaped plate 301 and four connecting rods 303. The four connecting rods 303 are fixedly installed on one side of the X-shaped plate 301, and the pressure plate 201 is slidably sleeved between the four connecting rods 303. The locking assembly 4 includes a screw 401 and a sliding ring 403. The screw 401 is rotatably installed inside the X-shaped plate 301, and the sliding ring 403 is slidably sleeved on the screw 401 by a thread. The arc-shaped rods 204 are adapted to the sliding ring 403.

[0025] Specifically, the first connecting assembly 2 also includes four first gaskets 202, all of which are fixedly installed on the side of the pressure plate 201 near the busbar 1. The second connecting assembly 3 also includes four second gaskets 302, all of which are fixedly installed on the side of the X-shaped plate 301 near the busbar 1.

[0026] Specifically, the locking assembly 4 also includes a hexagonal block 402, which is fixedly installed on one side of the screw 401.

[0027] In this embodiment, by using the hexagonal block 402, the operator can use a hexagonal wrench to rotate the hexagonal block 402 and thus rotate the screw 401.

[0028] Specifically, the locking assembly 4 also includes four insert rods 404, all of which are fixedly installed on one side of the sliding ring 403. Two through holes 205 are opened on one side of each of the two arc-shaped rods 204, and the insert rods 404 are adapted to the through holes 205.

[0029] Specifically, the second connecting component 3 also includes two limiting rods 306, both of which are fixedly installed on one side of the X-shaped plate 301. The outer circumferential wall of the sliding ring 403 has two limiting grooves 405, which are adapted to the limiting rods 306.

[0030] In this embodiment, the sliding ring 403 can be limited by the limiting rod 306, so that it will only slide with the rotation of the screw 401.

[0031] Specifically, the locking assembly 4 also includes a ratchet 406, a ratchet tooth 407, a paddle 408, and two springs 409. The ratchet 406 is fixedly sleeved on the screw 401. A mounting hole 304 is provided on one side of the X-shaped plate 301. The screw 401 is rotatably installed in the mounting hole 304. A circular groove 305 is provided on the inner wall of the mounting hole 304. The ratchet 406 is rotatably installed in the circular groove 305. The ratchet tooth 407 is slidably inserted into the X-shaped plate 301 and meshes with the ratchet 406. The paddle 408 is fixedly installed on one end of the ratchet tooth 407. Both springs 409 are fixedly installed between the paddle 408 and the X-shaped plate 301.

[0032] In this embodiment, the ratchet 407 engages with the ratchet 406 under the pull of the spring 409, which can prevent the screw 401 from reversing, thereby preventing the pressure plate 201 and the X-shaped plate 301 from becoming loose.

[0033] Working principle: In use, the busbars 1 to be connected are overlapped. Then, the four connecting rods 303 are passed through the overlapped busbars 1, and the four second washers 302 are brought into contact with the busbars 1. Then, the pressure plate 201 is fitted between the four connecting rods 303, and the four first washers 202 are brought into contact with the busbars 1. Then, the two rotating rods 203 are rotated so that the two arc-shaped rods 204 are parallel to the sliding ring 403. At this time, the hexagonal block 402 is rotated with a wrench, which drives the screw 401 to rotate. The rotation of the screw 401 will drive the sliding ring 403 to slide towards the two arc-shaped rods 204 through the thread. The sliding of the sliding ring 403 will drive the insertion rod 404 to insert into the arc-shaped rods 204. Through hole 205 on rod 204, sliding ring 403 will connect with arc rod 204. As sliding ring 403 continues to slide, it will exert a thrust on arc rod 204, which in turn will exert a thrust on the two rotating rods 203 and pressure plate 201, making pressure plate 201 in close contact with busbar 1. At the same time, sliding ring 403 will also exert a thrust on screw 401, which in turn will exert a thrust on X-shaped plate 301, making X-shaped plate 301 in close contact with busbar 1, thus tightly connecting busbar 1. Furthermore, ratchet 407 engages with ratchet 406 under the pull of spring 409, which can prevent screw 401 from reversing, thereby preventing pressure plate 201 and X-shaped plate 301 from becoming loose.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
