Abstract
This is new there is provided a kind of electromagnetic relay of contactor gap adjustment-free, and the electromagnetic relay is equipped with movable contact spring and static contact spring piece on base, it is characterised in that：The static contact spring piece is provided with a convex portion, and projection of the movable contact spring on static contact spring piece does not cover the convex portion；The base is provided with a positioning boss in static contact spring piece convex portion correspondence position, and the static contact spring piece convex portion is mutually leaned with base boss.This new cooperation by base boss or limited post and quiet spring convex portion, as long as quiet spring is in place, the gap between sound contact determines that, and then ensures the contactor gap between sound contact.Adjustment, the measurement in relay contact gap and the contactor gap adjustment operation of quiet spring press-in distance can so be saved.
Description
Technical field
The utility model is related to a kind of electromagnetic relay, more particularly to electromagnetism relay of the sound contact all inside the cavity
Device.
Background technology
As shown in figure 1, the electromagnetic relay for sound contact all inside the cavity, due to the position of contact, causes to touch
Gap between point is difficult to carry out direct measurement, can cause larger error in measurement indirectly.Need to solve contactor gap measurement
Problem.
Secondly because relay construction feature, the biggest factor of influencing contactor gap length is the distance of quiet spring press-in（Or
Person says the depth of quiet spring press-in）.Due to the scattered error and board consistency problem of base dimensions, it is difficult to the uniformity of quiet spring press-in,
Especially flattening relay, not only not easily passs through production automatically, and manual synchronizing gap is all not easy.
Content of the invention
In order to overcome the problems referred to above, the utility model provides a kind of mobilization production and contactor gap exempts from corrected rate and product
The electromagnetic relay that product uniformity is all improved.
New for the ease of understanding this, spy is specified below to the new direction that is related to：
This new described axial direction is the corresponding X-direction of viewing visual angle of base as shown in Figure 2, and X-direction is main view
Figure projecting direction.
For achieving the above object, this is new there is provided following two technical schemes：
Scheme one：
A kind of electromagnetic relay of contactor gap adjustment-free, the electromagnetic relay are equipped with movable contact spring and quiet on base
Reed, it is characterised in that：The static contact spring piece is provided with a convex portion with movable contact spring, and projection of the movable contact spring on static contact spring piece does not cover institute
State convex portion；The base is provided with a positioning boss, the static contact spring piece convex portion and base boss phase in static contact spring piece convex portion correspondence position
Lean.
The height that the boss is counted from susceptor surface is between 0.4mm-0.8mm.
The boss from susceptor surface count highly preferred for 0.6mm.
Scheme two：
A kind of electromagnetic relay of contactor gap adjustment-free, the electromagnetic relay are equipped with movable contact spring and quiet on base
Reed, it is characterised in that：The static contact spring piece is provided with a convex portion, and projection of the movable contact spring on static contact spring piece does not cover the convex portion；
The base is provided with a limited post or many limited posts in static contact spring piece convex portion correspondence position, and the static contact spring piece convex portion is limited with base
Position post is mutually leaned.
The height that the limited post is counted from susceptor surface is between 0.4mm-0.8mm.
The limited post from susceptor surface count highly preferred for 0.6mm.
Above two scheme can adopt following prioritization scheme：The convex portion extends towards X-axis positive direction.
Above-mentioned technical proposal is beneficial in that：
1st, this new cooperation by base boss or limited post and quiet spring convex portion, as long as quiet spring is in place, between sound contact
Gap determine that, and then ensure the contactor gap between sound contact.Can so save quiet spring press-in distance adjustment, after
The measurement in appliance contact gap and contactor gap adjustment operation.
2nd, this new contactor gap that can ensure that sound contact in batch production process, improve production efficiency.
Combine accompanying drawing by the following examples to be further introduced to originally new.

Specific embodiment
Embodiment 1
A kind of electromagnetic relay of contactor gap adjustment-free as Figure 2-3, the electromagnetic relay are filled on base 1
It is furnished with movable contact spring 2 and static contact spring piece 3, the static contact spring piece 3 is provided with a convex portion 31, and projection of the movable contact spring 2 on static contact spring piece 3 is not covered
The convex portion 31；The base 1 is provided with a positioning boss 11,3 convex portion 31 of the static contact spring piece in 3 convex portion of static contact spring piece, 31 correspondence position
Mutually lean with 1 boss 11 of base.
The height that the boss 11 is counted from 1 surface of base is between 0.4mm-0.8mm.
The boss 11 from 1 surface of base count highly preferred for 0.6mm.
Convex portion described in the present embodiment, in finger-shaped, and extends to most preferred embodiment towards X-axis positive direction.
Embodiment 2：
A kind of electromagnetic relay of contactor gap adjustment-free as illustrated in figures 4-5, the electromagnetic relay is on base 1 '
Movable contact spring 2 ' and static contact spring piece 3 ' is equipped with, the static contact spring piece 3 ' is provided with a convex portion 31 ', and movable contact spring 2 ' is on static contact spring piece 3 '
Projection does not cover the convex portion 31 '；The base 1 ' is provided with 4 limited posts 11 ', institute in 3 ' convex portion of static contact spring piece, 31 ' correspondence position
State 3 ' convex portion 31 ' of static contact spring piece mutually to lean with 1 ' limited post 11 ' of base.
' height that counts from susceptor surface is between 0.4mm-0.8mm to the limited post 11.
The limited post 11 ' from susceptor surface count highly preferred for 0.6mm.
The effect of base boss or limited post described in above-mentioned two embodiment：The height of limited post determines stationary contact position
Put, the distance of limited post to susceptor surface is about 0.6mm.
In above-mentioned two embodiment, quiet spring convex portion is mainly used in the limited post with base or boss coordinates, therefore the quiet spring
Lobe length should meet：I.e. convex portion allows for taking on limited post or boss, can play a part of positioning.
