The mechanism member 40 and the contact member 50 are located in the base 10. The mechanism member 40 includes a support base 41, a movable member 42 and a tension spring 43. The support base 41 is coupled to the movable member 42 and sleeved on a support shaft. The tension spring 43 is fixed at one end to the movable member 42, and the other end is fixed to one of the shafts disposed on the base 10. The contact 50 has a contact 51, and the contact 51 is disposed corresponding to the end of the movable member 42 to enable the movable member 42. The contacts 51 can abut each other to form electrical conduction.

At present, the components in the conventional circuit breaker, such as the movable member and the contact, are usually designed in a single design. For example, in the electrical system of the DC high voltage system, the breaking capacity is low, and the voltage capacity is small, which cannot meet the system requirements.

In view of the above reasons, the creator has actively studied and developed the experience of related product research and development for many years, and through continuous experimentation and improvement, finally developed this creation.

The main purpose of this creation is to provide a double-break structure for circuit breakers, which is suitable for use in electrical systems requiring a DC high voltage system, which can improve the breaking capacity and system voltage, and has high stability characteristics.

In order to achieve the above purpose, the present invention provides a double-breaking structure of a circuit breaker, which is assembled in a body, an upper cover is locked on the base body, and a handle is pivotally mounted on the base body; the circuit breaker double breaking structure The utility model comprises a mechanism component, a left contact and a right contact. The mechanism component comprises a linkage rod, a fixing seat is pivotally connected to the linkage rod, a tripping member is pivotally connected to the fixing seat, a left movable body and A right movable member is adjacent to and vertically disposed under the fixing seat, and a support shaft is disposed on the base body, and one ends of the two tension springs are respectively fixed on the left movable member and the right movable member, and the other ends are fixed The left contact is provided with a contact, and the contact of the left contact is corresponding to the left movable end, so that the left movable member and the contact can abut each other to form a loop conduction. The right contact is provided with a contact, and the contact of the right contact is arranged corresponding to the right movable end, so that the right movable member and the contact can abut each other to form electrical conduction.

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.

Please refer to FIG. 2 to FIG. 4 . FIG. 2 and FIG. 3 are three-dimensional exploded view and plan view of the double breaking structure of the circuit breaker applied to the circuit breaker, and FIG. 4 is a three-dimensional decomposition of the double breaking structure of the circuit breaker. Figure. The present invention relates to a circuit breaker double-breaking structure, which is assembled in a body 10, an upper cover 11 is locked on the base body 10, and a handle 12 is pivotally mounted on the base body 10.

The circuit breaker double-breaking structure includes a mechanism component 20, a left contact 30 and a right contact 32. The mechanism component 20 includes a linkage rod 21, and a fixing base 22 is pivotally connected to the linkage rod 21, and a tripping The member 23 is pivotally disposed above the fixed seat 22, and a left movable member 24 and a right movable member 25 are adjacent to each other and are pivotally disposed under the fixed seat 22. A support shaft 26 is disposed on the base 10, One end of the tension spring 27 is respectively fixed on the left movable member 24 and the right movable member 25, and the other end is fixed on the support shaft 26; the left contact member 30 is provided with a contact 31, and the contact of the left contact 30 31 is disposed corresponding to the end of the left movable member 24, so that the left movable member 24 and the contact point 31 can abut each other to form a loop conduction; the right contact member 32 is provided with a contact 33, and the right contact member 32 is The contact 33 is disposed corresponding to the end of the right mover 25, so that the right mover 25 and the contact 33 can abut each other to form electrical conduction.
