Description
Technical field
The utility model is related to a kind of electromagnetic relay, more particularly to a kind of push-down high-power magnetic relay.
Background technology
Relay is a kind of using extensive electronic component, and it is widely used in household electrical appliance, automobile, Industry Control, electricity
The fields such as Force system, communication device, one of the microminaturization of electromagnetic relay, high-power demand for development its developing direction.
The installation foot position size of relay is typically pressed use requirement and determined, usually the size of standard, such as many relays
Leading foot between size be converted into the multiple that metric system is 2.54 by English system, therefore, the design of relay product structure can be by
The structure and size of each parts in the influence of the pin position installation dimension of relay, such as relay, and then influence relay
All technical, under conditions of the appearance and size and relay leading foot spacing of restriction, existing electromagnetic relay is deposited
In two types：One be electromagnetic system space it is smaller, thus the driving source of electromagnetic relay is relatively small, uses the relay
Contact load transfer capability it is also relatively small, it is impossible to meet the requirement of user；Although two be the volume for increasing electromagnetic system,
But be due to electromagnetic system driving force it is relatively large, contact closure when contact touching counter-force it is also relatively large, movable contact production
Raw contact bounce causes the frequency and amplitude of contact chatter to increase, and arcing is also easy to produce between contact and ablation contact, so that in contact
Repeatedly trigger relay failure after action, having notably will occur contact on relay production line and be unable to adhesive and produce not
Certified products.
The content of the invention
Technical problem to be solved in the utility model, which is to provide one kind, to limit appearance and size and relay extraction
