Description
Technical field
The present invention relates to a kind of magnetic latching relays, and anti-scrapings and accurate positioning are assembled more particularly to a kind of contact portion
Magnetic latching relay.
Background technology
The structure of existing magnetic latching relay is made of magnetic circuit part, contact portion, pushing mechanism and pedestal.Magnetic circuit part
It is generally made of the magnetic circuit of two almost symmetries, including static magnetic conduction body component (i.e. yoke and iron core), movable magnetic conduction body component
(i.e. armature) and coil (i.e. bobbin and enameled wire), contact portion include dynamic spring part, quiet spring part, pushing mechanism generally by
Pushing block is taken on, and pushing mechanism is connected between movable magnetic conduction body component and dynamic spring part.Contact portion is magnetic latching relay
Executing agency, magnetic latching relay coil leads to direct impulse voltage, magnetic circuit part work, and pushing block pushes the dynamic of contact portion
Spring part makes dynamic and static contact, the actuating of relay, and keeps "on" position；Coil leads to reverse impulse voltage, the magnetic circuit part division of labor
Make, pushing block pushes the dynamic spring part of contact portion that dynamic and static contact is made to disconnect, relay involution, and keeps state of operating a switch.
Magnetic latching relay main application fields are electric-power metering, and major function is switch and metering.Due to magnetic keep after
Electric appliance load electric current is big (5A~200A), and it is big to be electrified for a long time calorific value, it is desirable that magnetic latching relay can be reliable in closing operation
It acts, contact portion remains reliable contacts, conducting after closing operation, energy reliable disjunction when operating of operating a switch, after operation of operating a switch
Contact portion remains off state.
Contact portion is typically mounted on pedestal, and contact portion is metalwork, and pedestal is plastic part, and contact portion is installed on
It is typically that the inserting position of metalwork (such as static contact spring piece, static contact spring piece lead-out tablet, dynamic spring lead-out tablet) is inserted into plastics when pedestal
In the slot of part (i.e. pedestal), metalwork scrapes plastic part and generates plastics bits when assembly, always is the problem of relay industry,
In order to reduce plastics bits, it usually is inserted into side chamfering in metalwork, chamfering is typically to be formed using press mode, in this way, pressing
Entering will bulge around place, and often chamfering position is the positioning datum of direction of insertion, be formed by after chamfering to
Outer bulging certainly will cause positioning datum size uncontrolled or need prodigious cost that could realize on mold.
