Description

Movable terminal clamping structure of circuit breaker

The present invention relates to a movable terminal clamping structure of a circuit breaker, and more particularly to a movable terminal clamping structure which is arranged inside the circuit breaker and can form a current path of the circuit breaker.

The circuit breaker can be used on the main switch and the current dividing control switch on the wiring. It is an important component of the protection electrical appliance. Its main function is to protect against short circuit and prevent serious overload. When the circuit breaker detects short circuit, leakage, severe overload When the problem occurs, the circuit breaker can immediately jump off to protect the line and the appliance.

As shown in FIG. 1 , the conventional circuit breaker includes an upper body 11 , a lower base 12 , a handle 20 , a linkage mechanism 30 , a front terminal structure 40 , and a movable terminal structure 60 . The upper base 11 and the lower base 12 are mutually connected to each other. The movable terminal structure 60 includes a movable terminal 61, a bracket conductor 62, a compression spring 63 and a gasket 64; when the handle 20 is pushed to an ON state, the linkage mechanism 30 is actuated, and the linkage mechanism 30 can be The movable terminal structure 60 is driven against the front terminal structure 40, and the terminal contacts form a current path.

The movable terminal 61 and the holder conductor 62 are sandwiched by the pressure spring 63 and the spacer 64, and the contact force of the pressure spring 63 and the spacer 64 is used to contact the movable terminal structure 60. The resistance is normal, so that the current can be normally turned on; but the clamping of the pressure spring 63 and the spacer 64 causes the number of parts of the movable terminal structure 60 to be large; and the width of the movable terminal structure 60 It will also be wider, making space utilization less.

In view of the above reasons, there is still room for improvement in the conventional movable terminal clamping structure. The present creator has actively studied and developed the experience of related product research and development for many years, and has finally developed this book through continuous trial and improvement. creation.

The main purpose of the present invention is to provide a movable terminal clamping structure of a circuit breaker, which is replaced by a spring piece instead of a conventional technique, which can reduce the number of parts used.

The secondary purpose of the present invention is to provide a movable terminal clamping structure for a circuit breaker, the width of which is narrower than that of the prior art, and the space utilization is better.

In order to achieve the above object, the present invention provides a movable terminal clamping structure of a circuit breaker, which is disposed inside a circuit breaker, and the circuit breaker includes a body, a handle, a linkage mechanism, a front terminal structure and a movable terminal structure; the body includes The upper body and the lower body, the handle is combined with the linkage mechanism, the linkage mechanism includes a link assembly, a fixing frame and a linkage rod shaft, the front terminal structure device is disposed on the lower base body, and the movable terminal structure comprises a movable body The terminal and the bracket conductor; the technical feature of the present invention is that the movable terminal structure uses a spring piece to clamp and fix the movable terminal and the bracket conductor, and the clamping force of the spring piece ensures that the contact resistance is normal and the current is normally turned on. .

In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are for reference and description only, and are not intended to limit the creation.

2 and FIG. 3, FIG. 2 is a perspective view of the circuit breaker, and FIG. 3 is a perspective view of a part of the circuit breaker and a movable terminal clamping structure of the circuit breaker; a movable terminal clamping structure of the circuit breaker, The device is disposed inside the circuit breaker. The circuit breaker includes a body 10, a handle 20, a linkage mechanism 30, a front terminal structure 40, and a movable terminal structure 50. The body 10 includes an upper body 11 and a lower base 12.

Please refer to FIG. 4 and FIG. 5 . FIG. 4 is an exploded perspective view showing a clamping structure of a movable circuit of a circuit breaker and a movable terminal clamping structure of the circuit breaker. FIG. The handle 20 is coupled to the linkage mechanism 30 and is in interlocking relationship with the linkage mechanism 30. The linkage mechanism 30 includes a link assembly 31, a fixing frame 32 and a linkage rod shaft 33. The front terminal structure 40 is disposed on the lower seat The movable terminal structure 50 is disposed on the linkage rod shaft 33. The movable terminal structure 50 includes a movable terminal 51 and a bracket conductor 52.

When the handle 20 is pushed to the ON state, the linkage mechanism 30 is driven to cause the linkage assembly 31 to actuate the linkage rod shaft 33 to drive the movable terminal structure 50 and the front end. The substructure 40 is in contact to allow the circuit breaker to form a current path.

The movable terminal structure 50 is characterized in that the movable terminal 51 and the bracket conductor 52 are clamped and fixed by the spring piece 53 , and the clamping force of the spring piece 53 ensures that the contact resistance is normal and the current is normally turned on; This creation improves the problem of the number of parts of the prior art, and also makes the width of the movable terminal structure 50 narrower than the conventional technique and has good space utilization.
