Problems solved by technology

[0002] At present, the breaking mechanism of the control and protection switching appliances provided on the market generally includes a base and a cover plate. The base is movable with a contact support passing through the cover plate. The contact support is provided with an electromagnetic pressure plate. Iron core, static iron core and other structures can swing, and then drive the contact support to move up and down. This segmented mechanism has a complex structure, takes up a large space, and has high cost. Moreover, the swing of the electromagnetic pressure plate drives the contact support to move up and down, which is easy to cause burning phenomenon. , thereby shortening the service life of the contacts in the base, and may also cause excessive pressure in the unilateral arc extinguishing chamber in the base

Abstract

The invention discloses an electromagnet control switch electromagnet thrust direction action structure which comprises a base and a cover plate, an electromagnetic mechanism and an operating mechanism are arranged on the cover plate, a contact support penetrating out of the cover plate is movably arranged in the base, and an electromagnetic pressing plate is arranged on the contact support. The structure is characterized in that the electromagnetic pressing plate is linked with the electromagnetic mechanism and the operating mechanism to drive the contact support to move up and down. The electromagnet thrust direction action structure of the electromagnet control switch can be linked with an electromagnetic mechanism and an operating mechanism, the structure is simpler, more space is saved, the cost is lower, and the contact support action accuracy can be ensured.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an electromagnet control switch electromagnet thrust direction action structure. Background technique [0002] At present, the breaking mechanism of the control and protection switching appliances provided on the market generally includes a base and a cover plate. The base is movable with a contact support passing through the cover plate. The contact support is provided with an electromagnetic pressure plate. Iron core, static iron core and other structures can swing, and then drive the contact support to move up and down. This segmented mechanism has a complex structure, takes up a large space, and has high cost. Moreover, the swing of the electromagnetic pressure plate drives the contact support to move up and down, which is easy to cause burning phenomenon. , thereby shortening the service life of the contacts in the base, and may also cause excessive pressure ...
