CONTACT STRUCTURE OF LOW-VOLTAGE ELECTRICAL APPARATUS |
摘要 |
The present invention discloses a contact structure of a low-voltage electrical apparatus. The contact structure is in a dual-breakpoint form, and comprises: two U-shaped static contacts, the U-shaped static contact enabling the current direction in the static contact to be opposite to the current direction in a movable contact; a contact bridge; two movable contacts, disposed on the contact bridge, and respectively corresponding to the two static contacts; a contact support member, disposed on the movable contacts and connected to the movable contacts; two main contact springs, symmetrically disposed under the movable contacts and forming an angle with the contact bridge; and a spring support member, disposed under the two movable contacts and connected to the two main contact springs. At a contact position of the static contact and the movable contact and at a repulsed open position of the static contact and the movable contact, the angle between the main contact spring and the contact bridge is between -² and +±. |
