Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a connection structure for circuit breakers. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time.

[0003] When installing a circuit breaker, it needs to be snapped into a rail and secured by a slot on the back and limit blocks on both sides. In the existing technology, the slot on the back of the circuit breaker is not convenient for manual installation and removal. It is inconvenient to manually install or remove the circuit breaker, and manual installation or removal requires the use of tools or manual pulling of the buckle on the back of the circuit breaker, which is not practical. Therefore, a new connection structure for circuit breakers needs to be designed to address the above problems. Utility Model Content

[0006] A connection structure for a circuit breaker includes a circuit breaker body. A first retaining plate is fixedly installed on the back of the circuit breaker body. A movable groove is formed on the back of the circuit breaker body. A movable plate is slidably installed inside the movable groove via a sliding mechanism. A connecting spring is installed inside the movable groove. The two ends of the connecting spring are elastically connected to the bottom of the movable groove and the bottom wall of the movable plate, respectively. A second retaining plate is fixedly installed on the outer wall of the movable plate. Two support rollers are rotatably installed on the outer wall of the circuit breaker body via a support mechanism. Multiple support blocks are fixedly installed on the outer wall of the circuit breaker body. A connecting plate is fixedly connected to the outer wall of two adjacent support blocks via an elastic mechanism. A connecting roller is rotatably installed between two adjacent connecting plates via a connecting mechanism.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as slide rods, moving plates and connecting springs, the moving plate can slide on the outer wall of the two slide rods under the elastic action of the connecting springs. This allows the position of the second clamping plate to be easily adjusted when the moving plate is moved under force, thereby realizing convenient connection and disassembly between the circuit breaker body and the clamping rail.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-8 A connection structure for a circuit breaker includes a circuit breaker body 1. A first locking plate 2 is fixedly installed on the back of the circuit breaker body 1. A movable groove is opened on the back of the circuit breaker body 1. A movable plate 4 is slidably installed inside the movable groove through a sliding mechanism. The sliding mechanism includes two sliding rods 3 fixedly installed inside the movable groove. Both sliding rods 3 slide through the movable plate 4. By restricting the two sliding rods 3, the movable plate 4 can only move axially along the outer wall of the two sliding rods 3. A connecting spring 5 is installed inside the movable groove. The two ends of the connecting spring 5 are elastically connected to the bottom of the movable groove and the bottom wall of the movable plate 4, respectively. A second locking plate 6 is fixedly installed on the outer wall of the movable plate 4. Two support rollers 8 are rotatably installed on the outer wall of the circuit breaker body 1 through a support mechanism. The support mechanism includes multiple support plates 7 fixedly installed on the outer wall of the circuit breaker body 1. The support rollers 8 are rotatably installed between two adjacent support plates 7.

[0026] Multiple support blocks 9 are fixedly installed on the outer wall of the circuit breaker body 1. The outer walls of two adjacent support blocks 9 are fixedly connected to connecting plates 11 through an elastic mechanism. The elastic mechanism includes a spring telescopic rod 10 fixedly installed on the outer wall of the support block 9. The telescopic end of the spring telescopic rod 10 is fixedly connected to the outer wall of the connecting plate 11. Connecting rollers 13 are rotatably installed between two adjacent connecting plates 11 through a connecting mechanism. The connecting mechanism includes a connecting shaft 12 rotatably installed between two connecting plates 11. The connecting rollers 13 are fixedly installed on the outer wall of the connecting shaft 12. Multiple actuating teeth 14 are fixedly installed on the outer wall of the connecting rollers 13. Each actuating tooth 14 is made of rubber. Rubber has good elasticity and softness, which allows it to form a tighter contact between the surface and the object, thereby increasing friction and improving the coefficient of friction.

[0027] When using this utility model, the second locking plate 6 can be moved, causing the moving plate 4 to slide along the outer wall of the two sliding rods 3. During the sliding process, the connecting spring 5 is pulled, and the distance between the second locking plate 6 and the first locking plate 2 gradually increases. Then, the first locking plate 2 and the second locking plate 6 can be placed on the outer walls of the rail. Then, the movement of the second locking plate 6 can be released. At this time, under the elastic action of the connecting spring 5, the moving plate 4 can slide back to its original position on the outer wall of the two sliding rods 3, and the distance between the second locking plate 6 and the first locking plate 2 can be reduced. Thus, the first locking plate 2 and the second locking plate 6 can be fixedly installed on the outer wall of the rail through cooperation, so as to realize the connection and fixation between the circuit breaker body 1 and the rail. Through the elastic action of the connecting spring 5, the position of the second locking plate 6 can be easily adjusted, so as to realize the convenient connection and disassembly between the circuit breaker body 1 and the rail.

[0028] When connecting the wire to the connection hole of the circuit breaker body 1, the wire can be placed between the support roller 8 and the connecting roller 13. Under the elastic pull of the spring telescopic rod 10, the connecting roller 13 can drive multiple actuating teeth 14 to squeeze the wire. At this time, the connecting roller 13 can be rotated by the cooperation of the connecting shaft 12. The connecting roller 13 can then actuate the wire through multiple actuating teeth 14, which makes it easier to move the wire into the connection hole. This increases the convenience of connecting the wire to the circuit breaker body 1. The rubber actuating teeth 14 can increase the friction with the outer wall of the wire, and due to the softness of the rubber, it can also avoid damage to the outer sheath of the wire. Furthermore, the clamping of the support roller 8 and the connecting roller 13 can prevent the wire from loosening.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
