Description

Technical Field

[0001] The utility model belongs to the technical field of copper busbar overlap, in particular to a copper busbar overlap plugging device. Background Art

[0002] The current process for overlapping copper busbars between distribution cabinets is to connect the copper busbars and circuit breakers with bolts. Since the copper busbar connection holes are basically punched in the factory, they are pre-assembled in the factory and then disassembled and reassembled on site. The on-site distribution cabinet installation often has dimensional deviations, resulting in misalignment of the copper busbar holes, affecting installation.

[0003] Furthermore, if the copper busbar holes are misaligned, preventing bolts from being inserted, on-site modifications are extremely difficult, and even the busbars may need to be removed and taken back to the factory for re-drilling, which is labor-intensive, time-consuming, and expensive. This is because the copper busbar itself is thick and conductive, so during installation, if the busbar and the mounting structure, such as the mounting hole position, do not align, the busbar can only be re-drilled during installation.

[0004] At the same time, the copper busbar is installed on it by means of bolts or the like. During actual use, when the copper busbar needs to be disassembled for power-off maintenance, a large number of bolt structures need to be removed from the copper busbar one by one. Since the copper busbar is installed in a distribution cabinet with complex circuits, the circuits and electrical components are spatially blocked, making it more troublesome to disassemble the copper busbar.

[0005] Therefore, in the actual working process, if there is a copper busbar quick connection device, it can reduce the rework and modification problems caused by the misalignment of the holes of the copper busbar and reduce the technical defects of the difficulty of disassembly and maintenance.

[0006] Based on the above background, the purpose of the present invention is to provide a copper busbar overlapping and plugging device.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A copper busbar splicing and plugging device comprises a splicing box body, wherein two sides of the splicing box body are respectively provided with plugging interfaces;

[0009] A splicing mechanism for splicing copper bars is installed in the splicing box, and the splicing mechanism includes splicing conductive plates symmetrically arranged on both sides;

[0010] During the bonding process, the copper busbar is in electrical contact with the bonding conductive plate;

[0011] The overlapping conductive plate is mounted on the inner side wall of the overlapping box body through a plurality of spring structures;

[0012] The overlapping conductive plates further include a plurality of upper slide rails slidably connected between the top positions of the overlapping conductive plates and a lower slide rail slidably connected between the bottom positions of the overlapping conductive plates;

[0013] The top of the overlapping conductive plate is threadedly connected to an upper sliding screw rod which is slidably connected to the upper slide rail, and the bottom of the overlapping conductive plate is threadedly connected to a lower sliding screw rod which is slidably connected to the lower slide rail.

The folded parts at both ends of the overlapping conductive plates form guide parts.

[0039] Example 1

[0040] like Figure 1-4 As shown, a copper busbar splicing and plugging device comprises a splicing box body 1 made of insulating resin material, wherein the splicing box body 1 is provided with plugging ports 11 on the front and rear sides respectively; the copper busbar is plugged in through the plugging ports 11.

[0041] In order to achieve overlapping of copper busbars in a simple and convenient manner without the need for bolt fastening, a overlapping mechanism 2 for overlapping copper busbars is installed in the above-mentioned overlapping box body 1. The overlapping mechanism 2 includes overlapping conductive plates 21 symmetrically arranged on both sides (during the overlapping process, the copper busbars are electrically contacted with the overlapping conductive plates 21).

[0042] The shape of the overlapping conductive plate 21 is as follows: the overlapping conductive plate 21 includes a rectangular portion 211 , and two ends of the rectangular portion 211 are integrally formed with folded portions 212 , and the folded portions 212 pass through the insertion port 11 .

[0043] The above-mentioned overlapping conductive plate 21 is installed on the inner side wall of the overlapping box body 1 through several spring structures; specifically, the spring structure includes a spring 23; a first spring column 22 is fixedly connected to the overlapping conductive plate 21 and is sleeved at one end position of the spring 23, and a second spring column is fixedly connected to the inner side wall of the overlapping box body 1 and is sleeved at the other end position of the spring 23.

[0044] During the operation, the operator inserts the copper busbar into the overlapping conductive plates 21 along the plug interface 11 on one side. The folded parts 212 at both ends of the overlapping conductive plates 21 form a guide part. After the copper busbar is inserted, the overlapping conductive plates 21 on both sides are squeezed away from each other. During the process, the spring is compressed. After the copper busbar is plugged in, the elastic restoring force of the spring 23 is used to fully squeeze the spring structure on the overlapping conductive plates 21 on both sides to fully squeeze the copper busbar and ensure the stability of the electrical connection.

[0045] This method allows the copper busbars to be connected in a plug-in manner during operation. The plug-in method is not only convenient for connection, but also enables quick connection and removal, greatly improving the convenience of copper busbar connection and reducing the difficulty of copper busbar installation.

[0046] Example 2

[0047] like Figure 1-4 As shown, based on the structure of Example 1, in order to increase the sliding flexibility and stability of the overlapping conductive plate 21, the overlapping conductive plate 21 also includes a plurality of upper slide rails 24 slidably connected between the top positions of the overlapping conductive plates 21 and a lower slide rail 26 slidably connected between the bottom positions of the overlapping conductive plates 21 (specifically, the top and bottom of the overlapping conductive plates 21 are respectively slidably connected with a pair of spaced upper slide rails 24 and a pair of spaced lower slide rails 26); the top of the overlapping conductive plate 21 is threadedly connected to an upper sliding screw slidably connected to the upper slide rail 24, and the bottom of the overlapping conductive plate 21 is threadedly connected to a lower sliding screw slidably connected to the lower rail 26.

[0048] Specifically, both the upper slide rail 24 and the lower slide rail 26 are provided with rectangular sliding openings (specifically, the upper slide rail 24 is provided with an upper rectangular sliding opening 241, and the lower slide rail 26 is provided with a lower rectangular sliding opening 261); the upper sliding screw 25 and the lower sliding screw 27 are slidably connected in the rectangular sliding openings.

[0049] The upper slide rail 24 and the lower slide rail 26 are fixedly connected to the side walls on both sides of the lap box body 1. At the same time, the upper sliding screw 25 and the lower sliding screw 27 are respectively integrally formed with a convex ridge 251 that supports sliding on the upper slide rail 24 and the lower slide rail 26.

[0050] During operation, when the overlapping conductive plate 21 slides, the overlapping conductive plate 21 slides on the upper slide rails 24 and the lower slide rails 26 at the top and bottom (during the sliding process, the upper sliding screw 25 and the lower sliding screw 27 slide in the upper rectangular slide 241 and the lower rectangular slide 261). In this way, the sliding stability of the overlapping conductive plate 21 is further improved.

[0051] Example 3

[0052] like Figure 1-4 As shown, this embodiment builds on the structure of Example 2, with arcuate protrusions 213 integrally formed on the mutually facing side walls of the rectangular portion 211; the convex surfaces of the arcuate protrusions 213 are arranged to face each other. The arcuate protrusions 213 are used to further fully squeeze and overlap the conductive plate 21 during operation, thereby increasing the stability of the electrical contact.

[0053] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
