Abstract

The utility model discloses an electromagnetic relay with limiting rebound. The electromagnetic relay comprises a shell, and a base, an iron core, an armature, a pushing piece, a first reed, a second reed, a first contact, a second contact and a coil terminal which are in the shell, the first reed has one end fixedly connected to the base and the other end suspended, the second reed has one end fixedly connected to the base and the other end connected to the pushing piece, the first contact fixed on the first reed is disposed opposite to the second contact fixed on the second reed, the pushing piece is fixedly connected to the armature, and the iron core and the coil terminal are respectively fixed on the base. A framework of the base is provided with a concave portion, and the pushing piece has a convex column adapting to the concave portion of the framework for limiting at the rear end of the pushing piece. The electromagnetic relay with limiting rebound has the convex column arranged at an overlapping portion of the rear end of the pushing piece and the framework of the base, and the convex column adapts to the concave portion of the framework of the base for limiting; and the electromagnetic relay with limiting rebound can offset forces generated by rebound of the reeds when the electromagnetic relay is changed to release from actuation, thereby decreasing the rebound time of a product.

Description

The electromagnetic relay of spacing rebound

Technical field

The utility model relates to electronic technology field, relates in particular to a kind of electromagnetic relay of spacing rebound.

Background technology

In fields such as communication apparatus, control automatically, household electrical appliance, auto electroincs, relay all may be used in every application scenario that needs circuit conversion.Relay belongs to a kind of electric control device, and its principle is to remove to control a kind of automatic switch of big electric current running with little electric current, plays effects such as automatic adjusting, safeguard protection, circuit conversion in the circuit of being everlasting.

Push jack is as a sub-systems of relay, and it is connected with armature and reed, be the decision product withstand voltage with an important critical component that opens and closes performance.When being gone to release by adhesive, because the elasticity of reed can produce bigger resilience force, there is the long defective of bouncing time in the relay that uses on the existing market.

The utility model content

To the weak point that exists in the above-mentioned technology, the utility model provides a kind of electromagnetic relay of spacing rebound, when relay goes to release by adhesive, and the strength in the time of can offsetting the reed resilience, the bouncing time of reduction product.

For realizing above-mentioned purpose; The utility model provides a kind of electromagnetic relay of spacing rebound; Comprise shell and the pedestal, iron core, armature, push jack, first reed, second reed, first contact, second contact and the coil terminals that are provided with in the enclosure; One end of said first reed be fixedly connected with pedestal and the other end unsettled; Said second reed, one end is fixedly connected with pedestal and the other end is fixedly connected with push jack, and first contact that is fixed on first reed is oppositely arranged with second contact that is fixed on second reed; Said push jack is fixedly connected with armature, and said iron core and coil terminals are separately fixed on the pedestal; The skeleton of said pedestal is provided with recess, and the afterbody of said push jack is provided with the skeleton recess is suitable and is used for spacing projection.

Wherein, the aft mounted projection of said push jack has two, and is symmetrically distributed in the push jack afterbody.

The beneficial effect of the utility model is: compared with prior art; The electromagnetic relay of the spacing rebound that the utility model provides; Afterbody and the overlapping part of pedestal skeleton at push jack are provided with projection, and make that the recess of this projection and pedestal skeleton is adaptive next spacing, when relay goes to release by adhesive; Strength in the time of can offsetting the reed resilience, the bouncing time of reduction product.

Embodiment

In order more clearly to explain the utility model, the utility model is done to describe further below in conjunction with accompanying drawing.

See also Fig. 1; The electromagnetic relay of the spacing rebound that the utility model provides;

Comprise shell

10 and 10 pedestal 11, iron core 12, armature 13, push jack 14, first reed 15, second reed 16, first contact 17, second contact 18 and coil terminals 19 are set in the enclosure; One end of first reed 15 be fixedly connected with pedestal 11 and the other end unsettled; Second reed, 16 1 ends are fixedly connected with pedestal 11 and the other end is fixedly connected with push jack 14, and first contact 17 that is fixed on first reed 15 is oppositely arranged with second contact 18 that is fixed on second reed 16; Push jack 14 is fixedly connected with armature 13, and iron core 12 is separately fixed on the pedestal 11 with coil terminals 19; The skeleton 20 of pedestal 11 is provided with recess 21, and the afterbody of push jack 14 is provided with and the skeleton 20 recesses 21 suitable spacing projections 22 that are used for.

Situation compared to prior art; The electromagnetic relay of the spacing rebound that the utility model provides; Afterbody and the overlapping part of pedestal skeleton at push jack are provided with projection, and make that the recess of this projection and pedestal skeleton is adaptive next spacing, when relay goes to release by adhesive; Strength in the time of can offsetting the reed resilience, the bouncing time of reduction product.

In the present embodiment, the aft mounted projection 22 of above-mentioned push jack 14 has two, and is symmetrically distributed in the push jack afterbody.Certainly, projection 22 can be designed to other shape, also can be designed to a plurality of; It is understandable that the utility model is not limited to the concrete shape and the quantity of projection 22, as long as adopt projection and recess to match; Realize the electromagnetic relay of spacing rebound function, no matter adopt which type of position limiting structure, only otherwise break away from the spirit of spacing rebound; All should think simple deformation or conversion, fall into the protection range of the utility model the utility model.Wherein, coil 23 is on the periphery of skeleton 20.

The utility model improves the skeleton 20 of push jack 14 and pedestal 11; A kind of simple in structure, handling ease, electromagnetic relay that finished product is low have been designed; Push jack 14 is except being connected with fixation and guaranteeing the voltage endurance capability between the armature that push jack possessed of general electromagnetic relay and reed; Also through the staggered safeguard structure between push jack and the skeleton stability of product and the bouncing time of reduction product are provided, the band that improves product carries the life-span.The utility model is reasonable in design, and is simple in structure, makes easily, and defect rate is low, and cost is low, suits to go up enforcement at all electromagnetic relays (the particularly less electromagnetic relay of structure), has promotional value widely.

More than the disclosed several specific embodiments that are merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection range of the utility model.
