The electromagnetic system comprises an iron core, a coil, a matched yoke iron and an armature iron component for pushing the moving reed, wherein, the armature iron component comprises a big armature iron, a small armature iron and a permanent magnet steel which are matched with each other. The utility model has the advantages that: due to the structural features of the moving reed, the contact set enables large contact follow and contact pressure, and the loading capacity of the contacts is improved greatly; as the leading-out end, the static sheet and the moving reed of the relay adopt cold punching technology to increase the external surface area, the welding and heat dissipation are easy, and the temperature rise of the contacts and terminals is low.
Description
Technical field
The utility model belongs to the electric equipment field, relates to a kind of single-phase magnetic latching relay.
Background technology
Existing single-phase magnetic latching relay, though the way of contact of multiple contact and magnetic structure form are arranged, have following shortcoming: contact force is little, the contact temperature rise influences the use of electronic electric energy meter.Correlation circumstance is the prior art that can consult, and this does not give unnecessary details.
The utility model content
The purpose of this utility model is to provide that a kind of simple and compact for structure, contact force is big, contact and the low a kind of single-phase magnetic latching relay of terminal temperature rise, overcomes the shortcomings such as " it are little contact force to occur, the contact temperature rise " that exists in the prior art.
For reaching above purpose, solution of the present utility model is:
A kind of single-phase magnetic latching relay is provided with contact sets and electromagnetic system in housing.After coil was encouraged by a pulse voltage, armature component promoted movable contact spring and makes moving contact and fixed contact closure; Behind the coil reverse energization, armature component resets, and promotes movable contact spring moving contact and fixed contact are disconnected.
Single-phase magnetic latching relay comprises housing, contact sets, electromagnetic system, is provided with contact sets and electromagnetic system in the housing, and this contact sets comprises the movable contact spring that promoted by electromagnetic system, and it is provided with moving contact; Also comprise the still that is provided with fixed contact that matches.
Further, this contact sets also comprises the splitter structure.
This splitter structure is provided with the arch form bending part.
This splitter structure comprises some folded mutually splitters.
This movable contact spring end is provided with the bending part of elongation.
This still and movable contact spring adopt the structure that increases external surface area in region of interest.
The structure of this increase external surface area is a sags and crests.
This electromagnetic system comprises iron core and coil, and the yoke that matches, promotes the armature component of movable contact spring.
This armature component comprises the big armature that cooperatively interacts, little armature and permanent-magnet steel.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
Contact sets is because of the design feature of its movable contact spring, can realize bigger contact tracking and contact force, so improved the load-bearing capacity of contact greatly, relay exit, still and moving plate adopt the cold stamping technology that increases external surface area, be convenient to welding and heat radiation, contact and terminal temperature rise are low.In the relay electro-magnetic system, the armature component moving linearly, armature travel is big, big, simple in structure being easy to of commutation power assembled, and armature component has the pushing block function concurrently.This single-phase magnetic latching relay contact load reaches 100A, obtains the good technical effect.
