Abstract
The utility model discloses a super-mini direct current relay with no energy consumption, consisting of a common super-mini direct current relay, a permanent magnet steel which is arranged on the exterior of the corresponding side of a moveable stationary iron of the common super-mini direct current relay, a shell of the relay is fixed with the magnet steel by a binder. The relay is made to keep the pick-up status relying on the magnetic force of the permanent magnet steel without consuming electricity. The improved relay can be applied particularly in the electrical apparatus, the power supply of whose relay is costly.
Description
The utility model relates to a kind of improvement of microminiature direct current relay, and especially permanent-magnet steel keeps.
The subminiature relay of people's use at present, all be not to be with permanent-magnet steel to keep, make relay remain on the adhesive operating state, just must satisfy the requirement of its operating voltage and electric current, therefore to make relay remain on the adhesive operating state for a long time, will consume the electric energy of some.And having a relay that permanent-magnet steel keeps, reasons such as, cost height big because of its complex structure, volume are difficult to be applied in a lot of fields.
The purpose of this utility model is, increases a permanent-magnet steel on the original paper of common microminiature direct current relay, makes it become the relay that the band permanent-magnet steel keeps performance, realizes common relay purpose of " zero power consumption " under the adhesive operating state.
The technical solution of the utility model is such: in the bottom of common subminiature relay, promptly the corresponding surface of moveable balance iron is set up a permanent-magnet steel, and the size of magnet steel and magnetic force is not returned after should be able to making the relay adhesive, can natural adhesive not be as the criterion after the release.The polarity that magnet steel is installed should be consistent with the electric power polarity of relay actuating coil, and promptly different in nature adhesive, the same sex discharge.According to this principle, as long as apply once (moment) forward current (rated operational current) to relay, relay is adhesive for a long time just: apply once (moment) reverse current again, relay just can discharge for a long time.This relay only needs one group of coil just can finish the adhesive of relay, discharges working procedure.
Advantage of the present utility model is: the magnetic force that relies on permanent-magnet steel makes relay remain on the adhesive operating state and consumed power not.Relay after the improvement is particularly useful for using in the very precious electrical equipment of some relay working powers.
Below in conjunction with accompanying drawing and instantiation the utility model is further described.
Accompanying drawing is the utility model zero energy consumption microminiature direct current relay structural representation.
Common microminiature direct current relay 1., 2. permanent-magnet steel is installed in the obverse outside of common microminiature direct current relay moveable balance iron 1., fixes with bonding agent between magnet steel and the relay1 case.
Claims (2)
1. on the original paper of common microminiature dc electric apparatus, increase a permanent-magnet steel, it is characterized in that: permanent-magnet steel (2) is installed in the obverse outside of moveable balance iron of common microminiature direct current relay (1), uses adhesive between magnet steel and the relay1 case.
2. relay according to claim 1 is characterized in that: described relay has one group of actuating coil.
