Problems solved by technology

The existing electromagnetic breaker has complex structure and large volume. In addition, the shell of the existing electromagnetic breaker only plays the role of encapsulation and protection, and has a single function, so that it needs more parts inside to realize the corresponding function.

Abstract

The invention relates to the technical field of power controllers, in particular to an electromagnetic breaker having the advantage of novel and compact structure. Based on the lever principle of a transmission rotating block and an electrode lever, the invention can serve the function of power-off protection by allowing a moveable metal core to shift back and forth along the axial direction under the action of electromagnetic induction of an electromagnetic coil to put the electrode lever and electrode terminal in a connected or disconnected state. Two groups of axial holes are formed on a housing in the invention, so that the transmission rotating block and the rotating shaft of the electrode lever can be inserted into the axial holes for rotation; and a return spring structure is arranged between the electrode lever and the inner wall of the housing, thus ensuring that the structure is more compact, the size is smaller and the electromagnetic breaker can be easily installed in a circuit board. Therefore, the invention has the characteristics of reliable, compact and novel structure, multifunctional housing and smaller size.

Description

technical field [0001] The invention relates to the technical field of power supply control devices, in particular to an electromagnetic breaker with a novel and compact structure. Background technique [0002] In the structure of the power supply circuit, in order to protect the circuit devices, an open circuit protection circuit is usually added to the power supply circuit, and the electromagnetic breaker is a commonly used component in the power supply circuit and has been widely used. The existing electromagnetic breaker has a complex structure and a large volume. In addition, the shell of the existing electromagnetic breaker only plays the role of encapsulation and protection, and has a single function, so that many components are required inside to realize the corresponding function. In view of this, it is necessary to provide a more reliable electromagnetic breaker with a compact and novel structure, a shell with multiple functions, and a smaller volume, so that it ca...
