Abstract
The utility model discloses a kind of dynamic contact group for driving electromagnetic relay, the movable contact spring of movable contact is provided with including top, movable contact spring bottom is provided with dynamic leading foot, feature is that the top arranged on left and right sides of movable contact spring respectively symmetrically offers the first strip slotted eye, advantage is that this moves contact group for that can reduce or eliminate contact bounce in driving electromagnetic relay, and then ensures that contact is reliable.
Description
Technical field
The utility model is related to a kind of electromagnetic relay, more particularly to a kind of dynamic contact for driving electromagnetic relay
Group.
Background technology
With the development of society, people are for the more and more diversified of the functional requirement of the complete machine using relay, this will
Ask the power switched of relay also increasing, contact load transfer capability increase, corresponding relay input power also increases,
Contact touching counter-force of the contact in closure is also relatively large, and movable contact produces the frequency and width that contact bounce causes contact chatter
Degree is increased, and is also easy to produce arcing between contact and ablation contact, so as to trigger relay failure after repeatedly being acted in contact, has notably
Contact will occur on relay production line to be unable to adhesive and produce defective work.
The content of the invention
Technical problem to be solved in the utility model be to provide it is a kind of for driving electromagnetic relay can reduce or
Contact bounce is eliminated so that it is guaranteed that the reliable electromagnetic relay of contact.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of moving for driving electromagnetic relay
Contact group, including top are provided with the movable contact spring of movable contact, and described movable contact spring bottom is provided with dynamic leading foot, described dynamic spring
The top arranged on left and right sides of piece respectively symmetrically offers the first strip slotted eye.
The first described strip slotted eye is horizontally disposed, the torque best results of movable contact spring drive movable contact at this moment.
In order to strengthen the sensitivity of dynamic contact group, described movable contact spring bottom is U-bend folded structure, described dynamic leading foot
Including connecting portion, kink and the lead division being fixedly connected to the front end with the U-bend folding part of described movable contact spring, so,
When dynamic contact group is applied to relay, dynamic leading foot and quiet extraction can just be adjusted by actual demand by changing kink size
The distance between pin.
The second strip slotted eye along its length is offered in the middle part of described movable contact spring, the second strip slotted eye is further reduced
The coefficient of elasticity of movable contact spring, it is ensured that the stability of contact action.
Compared with prior art, the utility model has the advantage of：Due to movable contact spring top arranged on left and right sides respectively symmetrically
The first strip slotted eye is offered, when dynamic contact group is applied to driving electromagnetic relay, promotion point of the catch bar to movable contact spring
The left and right both ends of the movable contact spring above the first strip slotted eye, make movable contact spring obtain the larger motive force of catch bar respectively
Afterwards, catch bar can be reduced in the case where ensureing certain contact force promotes movable contact spring to drive movable contact to touch the normal of normally opened quiet contact group
Contact bounce produced during stationary contact is opened, that is, reduces the frequency and amplitude of contact chatter or eliminates contact bounce, Jin Erti
The high reliability of contact.

Fig. 2 be the utility model embodiment in movable contact spring dimensional structure diagram；
Fig. 3 be the utility model embodiment in dynamic leading foot dimensional structure diagram；
Fig. 4 is that the stereochemical structure that the utility model embodiment is applied in contact system is intended to；
Fig. 5 is the dimensional structure diagram that the utility model embodiment is applied in relay.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As illustrated, a kind of dynamic contact group for driving electromagnetic relay, including top are provided with the dynamic of movable contact 1
Reed 2, the bottom of movable contact spring 2 is provided with dynamic leading foot 3, and respectively symmetrically level offers first to the top arranged on left and right sides of movable contact spring 2
Strip slotted eye 21, the bottom of movable contact spring 2 be U-bend folded structure, move leading foot 3 include be used to before the U-bend folding part of movable contact spring 2
Connecting portion 31, kink 32 and the lead division 33 being fixedly connected are held, the middle part of movable contact spring 2 offers the second strip along its length
Slotted eye 22, when dynamic contact group is applied to driving electromagnetic relay, catch bar 4 to the promotion point of movable contact spring 2 respectively the
The left and right both ends of the movable contact spring 2 of the top of one strip slotted eye 21, make movable contact spring 2 after the larger motive force of catch bar 4 is obtained,
Catch bar 4 can be reduced in the case where ensureing certain contact force promotes movable contact spring 2 to drive movable contact 1 to touch normally opened quiet contact group 5
Produced contact bounce during normally opened stationary contact 51, that is, reduce the frequency and amplitude of contact chatter or eliminate contact bounce, enter
And improve the reliability of contact.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment be only it is schematical, rather than restricted, this area it is common
Technical staff is not departing from the utility model objective and scope of the claimed protection situation under enlightenment of the present utility model
Under, many forms can be also made, these are belonged within protection of the present utility model.
