Abstract
The utility model discloses a connection structure between a dynamic reed and a pushing block of a relay, which comprises the dynamic reed and the pushing block. The pushing block is provided with two arms, opposite inner sides of the two arms are respectively provided with a fastening groove, and a convex block is respectively disposed in the middle portions of the fastening grooves; a flexible and foldable fin respectively arranged on two sides of the dynamic reed is formed by arranging a fin opening, and a notch is respectively arranged on the upper portions of the fins; and the upper portions of the fins of the two sides of the dynamic reed are respectively clamped in the corresponding fastening grooves of the two arms of the pushing block, and the notches of the fins are fastened with the convex blocks of the fastening grooves. In the structure, after a normally open contact set and a normally closed contact set of the relay are connected, the pushing block applies pressure to retain connection state of contacts, thereby leading bounce time of the two contact sets to be short, and flexibility characteristics of the dynamic reed ensures appropriate over travel among the dynamic reed and a reset static contact and a setting static contact, thereby the connection structure with simple structure and low manufacturing cost improves contact switching loading capacity and electrical endurance.
Description
Technical field
The utility model relates to a kind of electromagnetic relay, particularly relates to a kind of movable contact spring of relay and the syndeton between the pushing block.
Background technology
Existing electromagnetic relay has generally comprised contact portion, magnetic circuit part and pushing block.Contact portion includes normally closed static contact spring piece assembly, often opens static contact spring piece assembly and movable contact spring assembly, and these assemblies are packed in the base in the plug-in mounting mode, just can form stable, reliable contact portion.Magnetic circuit partly includes yoke, armature, bobbin and coil windings.Contact portion, magnetic circuit are partly packed into and just can be assembled into whole of relay in the base.In said structure, the action displacement of armature will just can pass to movable contact spring by pushing block, end at pushing block adopts the mode that clamps and armature head to form hinge joint, armature and pushing block serve as the relative rotation that axle can have certain angle with hinge joint place, the other end of pushing block is provided with projection, and this end stretches in the breach of movable contact spring with overlapping mode.During the coil no power of relay, the normally-closed contact group keeps on-state, and pushing block and movable contact spring are free overlap joint state; When the coil electricity of relay, armature moves to yoke, the hinge joint position drives the pushing block motion, pushing block passes to movable contact spring with the moving displacement of armature, the movable contact spring action, make that the normally-closed contact group disconnects, the normally opened contact winding is logical, and under the electromagnetic force effect that coil electricity produces, keep that the normally-closed contact group disconnects, the normally opened contact winding is logical.
Fig. 1 is the overall structural representation of existing relay, Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of existing relay, Fig. 3 is the movable contact spring of existing relay and the structural representation that pushing block overlaps, and Fig. 4 is the movable contact spring of existing relay and the schematic diagram of pushing block overlap joint assembling process.The relay of this structure, comprise base 1 ', pushing block 2 ', armature 3 ', yoke 4 ', bobbin 5 ', coil 6 ', normally closed static contact spring piece assembly 7 ', often open static contact spring piece assembly 8 ' and movable contact spring 9 '; Pushing block 2 ' front end be provided with two arms 21 ', two arms 21 ' front end respectively be provided with then be provided with on the projection 211 ' movable contact spring two breach 91 ', the breach 91 of two projections 211 of pushing block 2 ' front end ' snap in respectively, two correspondences of movable contact spring ' in, make and form overlap joint between pushing block and the movable contact spring, when pushing block 2 ' when moving forward, the projection 211 of pushing block 2 ' front end ' meeting ejection movable contact spring 9 ' travel forward, make movable contact spring 9 ' on moving contact with often open static contact spring piece assembly 8 ' fixed contact contact, and when pushing block 2 ' mobile backward, pushing block 2 ' not to movable contact spring 9 ' application of force, movable contact spring 9 ' dependence self elastic reset.The pushing block of existing this electromagnetic relay and the bridging arrangement of movable contact spring, can only realize the unidirectional delivery of armature displacement, promptly when armature travels forward, its moving displacement amount can pass to movable contact spring by pushing block, and armature resets when moving backward, armature can only drag pushing block and move backward, and movable contact spring then relies on self elastic force recovery fully.When this structure is used for magnetic latching relay, in the reseting procedure, because pushing block is not exerted pressure to movable contact spring, thereby the back contact group when closed the bouncing time of contact long, cause arc time long, bonding failure easily take place, because of the life-span of back contact group then very short.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of movable contact spring of relay and the syndeton between the pushing block are provided, after making that the normally opened contact group, normally-closed contact winding of relay is logical, pushing block all can be exerted pressure with the holding contact on-state, thereby the bouncing time of two pairs of contact sets is all very little, thereby the ability and the electric life level of contact switch load have been promoted, the characteristics that have simple in structure, low cost of manufacture, can suit to produce in enormous quantities.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of movable contact spring of relay and the syndeton between the pushing block comprise movable contact spring and pushing block; This pushing block one end is provided with two arms along its direction of motion, and two arms institute opposed inside is respectively equipped with a draw-in groove, and the middle part of each draw-in groove is respectively equipped with a projection; But the both sides of movable contact spring along its separately the direction of side be respectively equipped with the fin of a flexible bending, the top of fin is respectively equipped with a breach; The top of the fin of the both sides of movable contact spring is clipped in respectively in the draw-in groove of correspondence of two arms of pushing block, the holding and the both sides of movable contact spring are positioned in the draw-in groove of two arms of pushing block mutually of the breach of fin and the projection of draw-in groove.
