Description

A new type of bus Technical Fields

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

[0002] A circuit breaker is a switching device that can disconnect and connect load circuits, as well as disconnect faulty circuits, and prevent accidents from escalating while ensuring safe operation. Among circuit breakers, miniature circuit breakers are the most widely used. These miniature circuit breakers are applicable to various places such as industrial, commercial, high-rise, and residential buildings. Miniature circuit breakers are also one of the important power distribution electrical appliances in low-voltage power grid systems.

[0003] All outgoing lines in the distribution cabinet must be connected to circuit breakers before being led out. Multiple circuit breakers are typically installed horizontally side-by-side within the cabinet. Currently, the common technique is to directly connect each circuit breaker to the next using wires, and so on, until all circuit breakers are energized. However, this method is prone to misconnections and omissions, leading to short circuits or open circuits. Subsequently, circuit breaker busbars were developed, allowing multiple circuit breakers to be connected using a single busbar. Busbars offer advantages such as easy installation and good safety performance, and are therefore widely used.

[0004] Chinese utility model patent application number 202322972171.8 discloses an integrally molded electrical bus, including: a bus body, the bus body including a support plate, a plurality of inserts fixed on the support plate, and a plurality of grooves cut on the inserts to increase the insertion and extraction force between the device and the electrical switch, thereby reducing the probability of the device falling off and improving the safety of the device.

[0005] Chinese utility model patent application number 202420345871.6 discloses a busbar, which has a flame-retardant shell with two sliding grooves cut into the middle by a barrier section. After the first busbar and the second busbar are respectively assembled into the two sliding grooves, the terminals on the first busbar and the second busbar are exposed outside the flame-retardant shell, which facilitates wiring. There are two types of terminals: one is straight and the other is S-shaped. After the two types of terminals are staggered in the sliding grooves, the wiring positions at the ends will be on the same axis; the wiring is neat and beautiful.

[0006] Both types of busbars have the following drawbacks: Since the connectors / terminals of both busbars are integrally connected to the busbar body / busbar, and the busbar is connected to multiple circuit breakers arranged in a row via multiple connectors / terminals, and each is screwed in to achieve corresponding conduction; if a circuit breaker fails and needs replacement, because multiple circuit breakers are installed on the distribution cabinet's mounting rail using a clamping method, it is impossible to directly remove a damaged circuit breaker without disassembling the busbar. In this case, all the screws securing the busbar to the connectors / terminals on all circuit breakers must be loosened, and then the busbar must be removed relative to all circuit breakers before the damaged circuit breaker can be removed from the distribution cabinet's mounting rail. A new circuit breaker must then be installed on the mounting rail, and the busbar must be reinstalled on all circuit breakers, and all screws tightened to complete the repair. This entire process is extremely cumbersome and causes significant inconvenience to maintenance personnel.

[0007] In view of the above, the inventors propose the following technical solution. Invention content and utility model content:

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of busbar.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The novel busbar includes a busbar body and a number of inserts spaced apart at the lower end of the busbar body and electrically connected to the busbar body. The front end of the busbar body is provided with multiple sets of spaced-apart snap-fit ​​structures, wherein each set of snap-fit ​​structures includes a first elastic buckle and a second elastic buckle fixed to the front end of the busbar body and mirror-distributed, with a gap between the first elastic buckle and the second elastic buckle; each insert has a vertically distributed adjustment hole at its upper end. The insert passes through the adjustment hole and snaps with the first elastic buckle and the second elastic buckle to fasten the busbar body and the insert together, and the insert can slide up and down relative to the first elastic buckle and the second elastic buckle through the adjustment hole.

[0010] Furthermore, in the above technical solution, the first elastic buckle includes a first main body integrally connected to the front end of the busbar main body and a first buckle body integrally formed at the end of the first main body; the second elastic buckle includes a second main body integrally connected to the front end of the busbar main body and a second buckle body integrally formed at the end of the second main body; the first buckle body and the second buckle body are respectively fastened to the outer front edge of the adjustment hole on both sides of the insert to fasten the busbar main body and the insert together, and the insert can slide up and down relative to the first main body of the first elastic buckle and the second main body of the second elastic buckle through the adjustment hole.

[0011] Furthermore, in the above technical solution, the first elastic buckle includes a first main body integrally connected to the front end of the busbar main body and a first buckle body integrally formed at the end of the first main body; the second elastic buckle includes a second main body integrally connected to the front end of the busbar main body and a second buckle body integrally formed at the end of the second main body.

[0012] Furthermore, in the above technical solution, the front end of the first buckle body is provided with a first guide surface; the front end of the second buckle body is provided with a second guide surface.

[0013] Furthermore, in the above technical solution, a first limiting groove and a second limiting groove are provided on both sides of the adjustment hole; the first buckle body and the second buckle body respectively abut against the first limiting groove and the second limiting groove.

[0014] Furthermore, in the above technical solution, an elastic metal gasket is sleeved on the outside of the first body of the first elastic buckle and the second body of the second elastic buckle, and the elastic metal gasket is squeezed between the front end of the busbar body and the rear end of the insert.

[0015] Furthermore, in the above technical solution, the elastic metal gasket is a twisted disc-shaped gasket.

[0016] Furthermore, in the above technical solution, the guide portion at the lower end of the insert is also provided with a limiting groove.

[0017] Furthermore, in the above technical solution, one end of the busbar body is also connected to a rotatable guide arm that can be adjusted in angle.

[0018] Furthermore, in the above technical solution, a first through hole is provided at one end of the busbar body, and a second through hole is provided at the lower end of the guide arm. After the bolt passes through the second through hole and the first through hole in sequence, it is screwed and fixed with the nut. The bolt and the nut cooperate to clamp and fix the busbar body and the lower end of the guide arm together, forming an electrical connection.

[0019] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In specific use, this utility model inserts multiple plugs electrically connected to the main body of the busbar into multiple circuit breakers and secures them with the first screw, so that the entire busbar and multiple circuit breakers are electrically connected. These circuit breakers are all installed on the mounting rail of the distribution cabinet by means of a clamp. When a circuit breaker is detected to be damaged and needs to be replaced, it is only necessary to loosen the first screw that fixes the plug corresponding to the damaged circuit breaker and pull the plug upward directly. The plug will slide upward relative to the first body of the first elastic buckle and the second body of the second elastic buckle through the adjustment hole, so that the plug is detached from the damaged circuit breaker. At this time, the damaged circuit breaker is not restricted by the plug, so the damaged circuit breaker can be quickly removed to replace the new circuit breaker without pulling other plugs or removing other plugs relative to other undamaged circuit breakers. It can reduce the process, is extremely convenient to operate, and has extremely high maintenance efficiency, making this utility model highly competitive in the market. Figure description:

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] As shown in Figures 1-5, a new type of busbar includes a busbar body 1 and several inserts 2 spaced apart at the lower end of the busbar body 1 and electrically connected to the busbar body. In actual use, the busbar body 1 is electrically connected to the main switch 100, and the conductive part of the insert 2 is inserted into the circuit breaker 200. The first screw is screwed through the circuit breaker 200 and contacts the conductive part of the insert 2 to form electrical conduction.

[0027] This utility model makes the busbar body 1 and the insert 2 into a separate structure. The two are independent entities, but are connected together by assembly to form an electrical connection. The specific assembly structure is as follows: the front end of the busbar body 1 is provided with multiple sets of spaced-apart buckle structures 11, each set of buckle structures 11 including a first elastic buckle 111 and a second elastic buckle 112 fixed to the front end of the busbar body 1 and mirror-distributed, with a gap 110 between the first elastic buckle 111 and the second elastic buckle 112; each insert 2 is provided with a vertically distributed adjustment hole 21 at its upper end. The insert 2 passes through the adjustment hole 21 and then snaps and fixes itself to the first elastic buckle 111 and the second elastic buckle 112 to fasten the busbar body 1 and the insert 2 together. The insert 2 can slide up and down relative to the first elastic buckle 111 and the second elastic buckle 112 through the adjustment hole 21. In practical use, this utility model uses multiple plugs 2 electrically connected to the busbar body 1 to be inserted into multiple circuit breakers 200, and then fastened with a first screw, so that the entire busbar and multiple circuit breakers 200 are electrically connected. These circuit breakers are all installed on the mounting rail of the distribution cabinet by means of a clamp. When a circuit breaker is detected to be damaged and needs to be replaced, simply loosen the first screw fixing the plug 2 corresponding to the damaged circuit breaker, and directly pull the plug 2 upward with force to make the plug 2 pass through the adjustment hole 21 relative to the first... The first body 103 of the elastic buckle 111 and the second body 104 of the second elastic buckle 112 slide upward, causing the insert 2 to detach from the damaged circuit breaker. At this time, the damaged circuit breaker is not restricted by the insert 2, so that the damaged circuit breaker can be quickly removed to replace the new circuit breaker without pulling other inserts 2 or removing other inserts 2 relative to other undamaged circuit breakers. This reduces the number of steps, is extremely convenient to operate, and has extremely high maintenance efficiency, making this utility model highly competitive in the market.

[0028] The first elastic buckle 111 includes a first body 103 integrally connected to the front end of the busbar body 1 and a first buckle body 101 integrally formed at the end of the first body 103; the second elastic buckle 112 includes a second body 104 integrally connected to the front end of the busbar body 1 and a second buckle body 102 integrally formed at the end of the second body 104; the first buckle body 101 and the second buckle body 102 are respectively fastened to the outer front edge of the adjustment hole 21 on both sides of the insert 2 to fasten the busbar body and the insert together, and the insert 2 can slide up and down relative to the first body 103 of the first elastic buckle 111 and the second body 104 of the second elastic buckle 112 through the adjustment hole 21.

[0029] As the insert 2 passes through the adjustment hole 21 past the first elastic buckle 111 and the second elastic buckle 112, both the first elastic buckle 111 and the second elastic buckle 112 undergo outward compression deformation, causing the gap 110 to deform, so that the insert 2 passes through the adjustment hole 21 past the first elastic buckle 111 and the second elastic buckle 112, and thus fits and assembles with the front end of the busbar body 1.

[0030] To enable the adjustment hole 21 of the insert 2 to better pass over the first elastic buckle 111 and the second elastic buckle 112, the following design is made: a first guide surface 105 is provided at the front end of the first buckle body 101; a second guide surface 106 is provided at the front end of the second buckle body 102. When the two sides of the adjustment hole 21 of the insert 2 come into contact with the first guide surface 105 and the second guide surface 106, and the insert 2 is pushed further, the first guide surface 105 and the second guide surface 106 receive an inward tilting force, which in turn drives the first body 103 and the second body 104 to undergo elastic deformation from the outside to the inside, so that the adjustment hole 21 of the insert 2 can smoothly pass over the first elastic buckle 111 and the second elastic buckle 112 and be snapped and fixed with the first elastic buckle 111 and the second elastic buckle 112.

[0031] In some embodiments, a first limiting groove 211 and a second limiting groove 212 are provided on both sides of the adjustment hole 21; the first buckle body 101 and the second buckle body 102 abut against the first limiting groove 211 and the second limiting groove 212 respectively, thereby improving the stability of assembly.

[0032] In some embodiments, to make the assembly between the busbar body 1 and the insert 2 more stable, the following design is made: an elastic metal gasket 22 is sleeved on the outside of the first body 103 of the first elastic buckle 111 and the second body 104 of the second elastic buckle 112. The elastic metal gasket 22 is pressed between the front end of the busbar body 1 and the rear end of the insert 2, thereby using the elastic force of the elastic metal gasket 22 to form a more stable snap-fit ​​fixation between the insert 2 and the first elastic buckle 111 and the second elastic buckle 112, thereby making the assembly between the busbar body 1 and the insert 2 more stable and improving their conductivity. The elastic metal gasket 22 is a twisted disc-shaped gasket.

[0033] In some embodiments, the guide portion at the lower end of the insert 2 is further provided with a limiting groove, which is adapted to the first screw screw that is screwed on the circuit breaker 200. That is, after the first screw is tightened, the end of the first screw presses against the limiting groove, thereby preventing the insert 2 from accidentally coming off the circuit breaker 200 and ensuring the stability of the power supply.

[0034] In some embodiments, one end of the busbar body 1 is further connected to a rotatable guide arm 4 for adjusting the angle. This guide arm 4 is used to connect with the main switch 100. Since the guide arm 4 can rotate relative to the busbar body 1, it allows for angle adjustment when connected to the main switch 100, making installation more convenient.

[0035] The busbar body 1 is provided with a first through hole at one end, and the lower end of the guide arm 4 is provided with a second through hole. The bolt 42 passes through the second through hole and the first through hole in sequence and is screwed and fixed with the nut 43. The bolt 42 and the nut 43 cooperate to clamp and fix the busbar body 1 and the lower end of the guide arm 4 together, forming an electrical connection, and the assembly structure is stable.

[0036] In practical use, this utility model uses multiple plugs 2 electrically connected to the busbar body 1 to be inserted into multiple circuit breakers 200, and then fastened with a first screw, so that the entire busbar and multiple circuit breakers 200 are electrically connected. These circuit breakers are all installed on the mounting rail of the distribution cabinet by means of a clamp. When a circuit breaker is detected to be damaged and needs to be replaced, simply loosen the first screw fixing the plug 2 corresponding to the damaged circuit breaker, and directly pull the plug 2 upward with force to make the plug 2 pass through the adjustment hole 21 relative to the first... The first body 103 of the elastic buckle 111 and the second body 104 of the second elastic buckle 112 slide upward, causing the insert 2 to detach from the damaged circuit breaker. At this time, the damaged circuit breaker is not restricted by the insert 2, so that the damaged circuit breaker can be quickly removed to replace the new circuit breaker without pulling other inserts 2 or removing other inserts 2 relative to other undamaged circuit breakers. This reduces the number of steps, is extremely convenient to operate, and has extremely high maintenance efficiency, making this utility model highly competitive in the market.

[0037] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
