Description
Technical field
The utility model relates to a kind of novel relay construction, push card and movable contact spring in specifically a kind of relay
Connection structure.
Background technique
Relay is a kind of electronic control device, plays the work such as automatic adjustment, safeguard protection, conversion circuit in circuit
With.Its working principle is to add certain voltage at coil both ends, will pass through certain electric current in coil, thus in magnetic circuit
Upper generation galvanomagnetic-effect, armature will overcome the pulling force of return spring to be drawn to iron core under the action of electromagnetic attracting force, thus band
The stationary contact on movable contact and quiet spring on dynamic spring is attracted, and reaches conducting effect in circuit.
Existing relay mainly includes pushing card structure, left dynamic spring part, right dynamic spring part.The dynamic spring part in a left side and the right side are dynamic
The connection structure of spring part is different, and two sides are connect using the hook of different size and width with push card, and the shape of push card is also
Setting can be respectively corresponded with left and right dynamic spring part, cause the movement force unbalance of push card, in relay work, due to
Relay contact is electrified for a long time work, causes the temperature rise of movable contact spring part higher, and the narrow hook portion of the dynamic spring in a left side is compared to right dynamic spring
Partial heat dissipation area is small, and entire left dynamic spring part spring portion temperature more dynamic than the right side is high, and the push card in left side is caused to be melted vulnerable to heat
Deformation, the clamping anti-falling effect of hook portion easily reduces or disappears at this time；And since the armature of relay has in movement
Certain impact vibration causes push card to move spring head from left side and disengages, so that relay be made to lose along with external vibration
Effect.

Intimate surface contact and the clamping of the grab protrusion of narrower width, grab protrusion and wide grab.Grab protrusion reduces dog hole and width
The gap of grab reduces the activity that movement generates, and reduces vibration, improves the service life of product.
Further, the wide grab is molded over the top center of left dynamic spring and right dynamic spring, the width of the dynamic spring in a left side and right dynamic spring
Grab bending direction is identical, and the width of wide grab is greater than 2/3 or more of left dynamic spring or right dynamic spring width.Wide grab bending direction phase
Together, the moving direction same movement for driving push card reduces the abrasion of elastomeric element, improves traveling comfort, wide grab
There are enough width to realize that the connection of movable contact spring and push card, connection are reliable.
Further, the lower part of the left dynamic spring and right dynamic spring forms elastic bending, and elastic bending is semicircle, and
It is shaped to double-layer structure, the elastic bending of spring and right dynamic spring is moved towards unanimously in a left side.It is whole to same direction fortune to realize push card
It is dynamic, original necessary elastic construction has been subtracted, the better material of intensity can be used, has promoted reliability.
Further, the top of the left dynamic spring and right dynamic spring all forms contact contact portion, contact contact portion and relay
Stationary contact on device is correspondingly arranged.This contact contact portion is movable contact, when push card is affected by magnetic forces mobile, band movable contact
Contact portion and stationary contact, which are connected, to be powered.
The utility model compared with prior art, has the following advantages that and effect：By two wide hook structure combine come
Guarantee that push card is reliably connected together with dynamic spring, ensure that push card cannot fall off from two movable contact spring heads, ensure that
The reliability of relay product.This structure, which is mainly improved, to be made of left and right moving anchor portion with push card, by dynamic spring part
Hook portion structure design to guarantee its installation strength, thus ensure that push card cannot be completely fallen off from movable contact spring head,
Abjection.At work, the direction of motion of left and right movable contact spring is same direction to the structure.The crotch structure on movable contact spring head can be same
When be assembled in the square groove of push card the right and left, the versatility of structure is good.
