The invention discloses a self-locking device for safe insertion and removal of a circuit breaker, which solves the problem that the plug-in circuit breaker does not have a self-locking function and can be directly inserted and removed during use, causing accidental damage to equipment connected to the circuit breaker, including A housing, one end of the housing is connected with a plug, the top of the other end of the housing is equipped with a vent, the bottom of the other end of the housing is connected with a display light, the bottom of the housing is fixed with wires, the inner side of the plug is sleeved with a first connecting plate, and the top of the first connecting plate is The bump is fixed, the bottom end of the first connecting plate is installed with the fourth connecting plate, one end of the fourth connecting plate is connected with the first fixing plate, the top of the first fixing plate is fixed with the second connecting plate, and the top of the second connecting plate is connected with the second connecting plate. A splint, the bottom end of the first fixing plate is fixed with the third connecting plate, and one end of the fourth connecting plate is connected with the second fixing plate. The present invention has a self-locking function, and it cannot be directly plugged and pulled out during use, so as to avoid the equipment connected to the circuit breaker. Can cause accidental injury.
Description
A self-locking device for safe plugging and unplugging of circuit breakers technical field [0001] The invention belongs to the technical field of circuit breakers, and in particular relates to a self-locking device for safe plugging and unplugging of circuit breakers. Background technique There are many types of circuit breakers, and the plug-in circuit breaker is widely used as a daily high-power electrical appliance. It can separate or connect the circuit breaker and the socket in the way of plugging and unplugging. This structure is convenient for installation and later In order to improve the safety of plug-in circuit breakers, the research on the self-locking device for safe plug-in circuit breakers is beneficial to Improve the safe use of circuit breakers. However, the current plug-in circuit breaker can be directly plugged and unplugged during use, which will cause damage to the equipment connected to the circuit breaker. The problem of accidental injury, th...
