[0002] A circuit breaker is a switch device that can close, carry and disconnect the current under normal circuit conditions and close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over-underheating relays. Moreover, it is generally not necessary to change parts after breaking the fault current.

[0003] When installing an existing circuit breaker, it is usually necessary to use tools to continuously tighten multiple screws or bolts to install the circuit breaker. Although this installation method is effective, it consumes a lot of time and manpower. Utility Model Content

[0006] The beneficial effects of the utility model are as follows: the utility model sets a groove, when the circuit breaker switch body is installed, pressing the clamping rod will squeeze the telescopic rod at the same time, and then shorten the spring's own spacing until the clamping rod is retracted into the plug plate, and then the plug plate is inserted into the groove from the front, and the clamping rod rebounds through the elasticity of the spring, so that the clamping rod is clamped into the card slot, and the installation of the circuit breaker switch body can be completed. When the circuit breaker switch body needs to be disassembled, the above steps can be repeated, reducing manpower and time. The utility model is provided with a disassembly plate, so that the disassembly plate has the advantage of disassembly, and the disassembly plate can be removed by screwing the screw, which is convenient for disassembly and replacement of the disassembly plate at a later time.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] like Figures 1 to 5 As shown, the circuit breaker switch of this embodiment includes a connecting plate 1, and the left and right sides of the connecting plate 1 are fixedly connected with a fixing plate 2, a positioning hole 3 is provided inside the fixing plate 2, a groove 4 is provided inside the connecting plate 1, and a clamping groove 16 is provided on the top wall of the connecting plate 1, a clamping rod 5 is clamped inside the clamping groove 16, a spring 6 is fixedly connected to the bottom of the clamping rod 5, a telescopic rod 7 is inserted inside the spring 6, and a plug plate 8 sleeved on the surface of the clamping rod 5 and the spring 6 is fixedly connected to the bottom of the telescopic rod 7, and a circuit breaker switch body 9 is provided on the front of the plug plate 8.

[0014] refer to Figure 2 The left and right sides of the plug board 8 are fixedly connected with a disassembly plate 10, and the disassembly plate 10 and the inside of the circuit breaker switch body 9 are movably connected with screws 11 through threads.

[0015] In this embodiment, the disassembly plate 10 is provided so that the disassembly plate 10 has the advantage of being disassembled. The disassembly plate 10 can be disassembled by screwing the screws 11, so that the disassembly plate 10 can be disassembled and replaced later.

[0016] refer to Figure 5 A through opening 12 is provided inside the plug plate 8, and a connecting door 17 is movably connected inside the through opening 12.

[0017] In this embodiment, the through opening 12 is provided, and the through opening 12 and the connecting door 17 cooperate with each other, so that it is convenient for personnel to open the inside of the plug board 8, and to perform inspection and maintenance on the device inside the disassembly board 10 at a later time.

[0018] refer to Figure 4 A rubber pad 13 is arranged inside the groove 4 , and the rubber pad 13 is in contact with the plug board 8 .

[0019] In this embodiment, the rubber pad 13 is provided. When a person inserts the plug board 8 into the groove 4, the plug board 8 and the rubber pad 13 will fit together. The rubber pad 13 has the advantages of anti-slip and shock absorption, and can improve the installation stability of the plug board 8.

[0020] refer to Figure 3 The surface of the spring 6 is provided with a shot peening coating 14 .

[0021] In this embodiment, a shot peening coating 14 is provided to spray high-speed projectiles onto the surface of the spring 6, so that the surface layer of the spring 6 undergoes plastic deformation, forming a reinforcement layer of a certain thickness. A higher residual stress is formed in the reinforcement layer. Due to the presence of compressive stress on the surface of the spring 6, a part of the anti-stress can be offset when the spring 6 is under load, thereby improving the fatigue strength of the spring 6 and increasing the service life of the spring 6.
