Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker which is convenient for disassembly and assembly. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers can protect power lines and motors, etc., and can automatically cut off the circuit when they are seriously overloaded or short-circuited or undervoltage. Its function is equivalent to the combination of a fuse switch and an over-underheating relay.

The left and right side walls of the lower block 3 are provided with a socket A13. The slide A5 and the slide B6 are provided with a movable groove 14 aligned with the socket A13. The lower plate 9 is provided with a socket B15 aligned with the movable groove 14. The fixed column 11 is inserted into the socket A13, the movable groove 14, and the socket B15 and then abutted against the lower plate 9. The slide A5 and the slide B6 are provided with a slot 16 on one side wall close to each other. A magnet 17 is fixedly provided at one end of the connecting column 12. The other end of the connecting column 12 is inserted into the slot 16 and is slidably connected with the slide A5 and the slide B6. The rear side wall of the block B7 is an inclined surface.When the utility model is installed, the fixed column 11 is inserted into the jack A13, the movable groove 14, and the jack B15 and then is in contact connection with the lower plate 9, so that the lower plate 9 is fixed to the lower block 3; the top end of the electrical guide rail is inserted into the gap between the clamping block A4 and the housing 1 and then is in contact connection with the upper block 2, the bottom end of the electrical guide rail is in contact connection with the clamping block B7, and the housing 1 is squeezed backward, so that the electrical guide rail squeezes the clamping block B7, and then squeezes the spring 10 to contract it, so that the carriage A5 and the carriage B6 move downward, and the clamping block B7 moves downward. After the electrical guide rail pushes open the clamping block B7, the bottom end of the electrical guide rail will be inserted into the gap between the clamping block B7 and the housing 1 and is in contact connection with the lower block 3. After the extrusion force disappears, the spring 10 rebounds to make the clamping block B7 return to its position, so that the housing 1 is clamped on the electrical guide rail through the clamping block A4 and the clamping block B7, without the need for tools, which plays the role of convenient installation; when the carriage A5 and the carriage B6 move, the fixed column 11 is inside the movable groove 14 and will not interfere with the carriage A5 and the carriage B6; when the utility model is disassembled, the fixed column 11 is removed to be separated from the lower plate 9 and the lower block 3, so that the lower plate 9 is slidably arranged on the lower block 3. The pull column 26 is pulled to make the connecting columns 12 on the carriage A5 and the carriage B6 move towards each other and are magnetically attracted and connected by the magnet 17. The connecting column 12 is pressed to make the carriage A5 and the carriage B6 move downward, driving the spring 10, the lower plate 9 and the clamping block B7 to move.

At this time, the clamping block B7 is located below the electrical guide rail, and the spring 10 will not rebound. The housing 1 is pulled forward to be disassembled, without the need for tools, which plays the role of convenient disassembly; in summary, the utility model connects the carriage A5 and the carriage B6 together through the connecting column 12 and the magnet 17. When disassembling, pressing the connecting column 12 can drive the carriage A5 and the carriage B6 to move, without the need to use multiple tools to respectively turn the carriage A5 and the carriage B6. By inserting and pulling out the fixed column 11, the connection relationship between the lower plate 9 and the lower block 3 is switched. Therefore, the spring 10 can rebound and reset during installation for convenient installation, and the spring 10 will not rebound and reset during disassembly, without the need to always hold the carriage A5 and the carriage B6, having the beneficial effects of convenient installation and disassembly, and solving the problem that after the buckle is installed, it usually rebounds through the spring 10. Therefore, during disassembly, all the buckles need to be turned down and held at the same time to disassemble the circuit breaker. This disassembly method usually requires both hands to operate multiple tools, resulting in inconvenient disassembly of the circuit breaker.
