Technical Field
[0001] The utility model relates to the technical field of electric power equipment, and more specifically, to a pluggable busbar. Background Art
[0002] The busbar is a copper or aluminum busbar that connects the main switch in the power cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to be used as a conductor. Depending on the circuit requirements, it is usually necessary to connect two or more busbars together.
[0003] At present, in the existing technologies on the market, busbars are mostly fixed by welding or bolting. Although welding is relatively strong, it is troublesome to install and difficult to disassemble. Bolt fastening has problems such as cumbersome installation, difficult disassembly, and poor contact after long-term use.
[0004] For example, authorization announcement number CN215299520U discloses a busbar overlapping structure, in which the busbar bodies are overlapped by the toothed overlapping surfaces and fixed together by fastening bolts corresponding to the threaded through holes. This structural design increases the contact area at the busbar overlap, and can effectively avoid the phenomenon of increased resistance and subsequent local discharge due to poor contact between the busbar bodies or too small contact surface, thereby extending the service life of the busbar or equipment.
[0005] Although the above solution avoids connecting the two busbars by welding, the screw connection also has the problem of cumbersome installation. Utility Model Content
[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a pluggable busbar that can simplify the installation and replacement process of the busbar and reduce the operating difficulty and time cost.

The overlapping busbar is connected to the connecting part, and a fastening component is provided between each set of overlapping busbars and the connecting part.
[0010] The fastening assembly includes a socket strip and a fastener. The socket strip has two socket strips, which are respectively connected to two connecting plates. A docking plate is provided at the lower end of the socket strip, and a connecting hole is provided on the docking plate. The socket strip and the connecting plate are penetrated by hexagon socket screws to realize the connection between the socket strip and the busbar body. The overlapping busbar is placed between the two socket strips, and the socket strip is placed in the fastener.
[0011] The utility model is further configured as follows: the fastener includes two fastening blocks and a latch pin, the side walls of the two fastening blocks are provided with grooves, the two fastening blocks are arranged opposite to each other, a placement groove for the plug strip to pass through is formed between the two fastening blocks, the outer walls of the two fastening blocks are provided with positioning holes, the latch pin passes through the positioning holes, and is fixed by a nut.
[0012] The utility model is further configured as follows: a gasket and a spring are sleeved on the latch pin, and the other end of the spring contacts the outer wall of the fastening block.
[0013] The utility model is further configured as follows: the upper end of the plug strip is bent, and a slot for the overlapping female plug strip to be inserted is formed between the two plug strips.

[0023] like Figures 1 to 3 As shown,
[0024] The pluggable busbar comprises a busbar body 1 and a lapped busbar 2 connected to the busbar body 1. The busbar body 1 is provided with a plurality of connection parts 3. The connection parts 3 include two connection plates 4. The connection plates 4 are provided with a plurality of ejector pins 19. The connection plates 4 are fixedly connected to the busbar and are used to determine the installation position of the lapped busbar 2.
[0025] A plurality of fixing holes 5 penetrating the busbar body 1 and the connecting plate 4 are equidistantly provided on the connecting plate 4. The overlapping busbars 2 are connected to the connecting portion 3. A fastening assembly 6 is provided between each group of overlapping busbars 2 and the connecting portion 3. The overlapping busbars 2 are connected to the busbar body 1 through the fastening assembly 6.
[0026] The fastening assembly 6 includes a socket strip 7 and a fastener 8. The socket strip 7 has two socket strips, which are respectively connected to two connecting plates 4. The upper end of the socket strip 7 is bent, and a slot 18 for the overlapping mother socket strip 7 to be inserted is formed between the two socket strips 7, so that the overlapping mother strip 2 can be easily inserted into the slot 18.
[0027] A docking plate 9 is provided at the lower end of the socket strip 7, and a connecting hole 10 is provided on the docking plate 9. The socket strip 7 is connected to the mother bar body 1 by means of a hexagon socket screw 11 penetrating the docking plate 9 and the connecting plate 4. A docking hole 20 is provided on the docking plate 9 for the ejector pin 19 to extend into. The socket strip 7 is positioned by inserting the ejector pin 19 into the docking hole 20.
[0028] The overlapping busbar 2 is placed between two plug-in strips 7 , and the plug-in strips 7 are placed in fasteners 8 . The fasteners 8 are locked to fix the overlapping busbar 2 by the plug-in strips 7 .
[0029] The fastener 8 includes two fastening blocks 12 and a latch 13. The side walls of the two fastening blocks 12 are provided with grooves. The two fastening blocks 12 are arranged opposite to each other. A placement groove 14 for the extension cord 7 to pass through is formed between the two fastening blocks 12. The outer walls of the two fastening blocks 12 are provided with positioning holes. The latch 13 passes through the positioning holes and is fixed by a nut 15. A gasket 16 and a spring 17 are sleeved on the latch 13. The other end of the spring 17 is in contact with the outer wall of the fastening block 12. The fastening block 12 is squeezed by the elastic force of the spring 17, so that the fastening block 12 fixes the extension cord more firmly.
[0030] Working principle: When in use, place the docking plate 9 on the connecting plate 4, and pass the ejector pin 19 through the docking hole 20, then fix the power strip on the busbar body 1 by passing the hexagon socket screw 11 through the connecting hole 10, then place the two fastening blocks 12 on both sides of the power strip respectively, then put the gasket 16 and the spring 17 on the outer peripheral wall of the pin 13, and then insert the pin 13 into the positioning hole, so that the pin 13 passes through the two fastening blocks 12, and then fix the pin 13 at one end relative to the positioning hole by the nut 15. When the overlapping busbar 2 needs to be installed, it only needs to be inserted into the slot 18. Since the spring 17 is elastic, it can adapt to the overlapping busbar 2 when it is inserted and apply a constant pre-tightening force to avoid contact loosening caused by factors such as thermal expansion and contraction.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
