First embodiment

According to the assembly schematic diagram of the spring plate structure 1 and the connecting plate structure 2 in the utility model shown in fig. 1, the utility model discloses a movable spring piece, which comprises:

The spring plate structure 1 comprises a first spring plate 11 and a second spring plate 12 arranged on the first spring plate 11, wherein the free end of the first spring plate 11 is used for installing the movable contact 3;

the connecting piece structure 2 is provided with a deformation adjusting groove 21, the connecting piece structure 2 is arranged at the free end of the first reed 11, the second reed 12 is stressed to deform towards the inside of the deformation adjusting groove 21 after the movable contact 3 and the fixed contact 4 are closed until the second reed 12 abuts against the groove bottom of the deformation adjusting groove 21, so that the contact pressure between the movable contact 3 and the fixed contact 4 is enhanced by matching with the first reed 11.

In this embodiment, when the movable spring element is applied to the relay, the armature 6 first drives the movable contact 3 on the first spring 11 to close and contact to the fixed contact 4 under the attraction of the electromagnet 5, after the movable contact 3 and the fixed contact 4 are closed, the armature 6 continues to move beyond the range in the direction of the electromagnet 5, and as the armature 6 gets closer to the electromagnet 5, the second spring 12 is driven to deform towards the deformation adjusting groove 21, the deformation is changed into elastic deformation, and the deformation adjusting groove 21 provides a deformation space and a buffer distance for the second spring 12 until the second spring 12 abuts against the groove bottom of the deformation adjusting groove 21. At this time, the first spring piece 11 and the second spring piece 12 are elastically deformed together to press the movable contact 3 and the stationary contact 4, and form an elastic reaction force together.

As can be seen from the graph of the change of the attraction reaction force with the magnetic gap according to the present utility model shown in fig. 5, the dotted line portion in fig. 5 is a coil attraction force curve, that is, a change curve of the attraction force of the electromagnet 5 to the armature 6, and the solid line portion is a change curve of the elastic reaction force generated by the second spring 12 with the movement stroke of the armature 6 in the present embodiment. Wherein, the abscissa is the angle change axis between the armature 6 and the electromagnet 5, and the ordinate is the magnetic force change axis.

Since the electromagnetic attractive force has a small change rate at the position of the solid line part break point corresponding to the abscissa 0.9 in fig. 5 before the movable contact 3 and the stationary contact 4 are closed, the electromagnetic attractive force between the armature 6 and the electromagnet 5 is used for overcoming the counter force of the tension spring connected between the armature 6 and the body, so that the tension spring with a small elastic coefficient is designed to provide the elastic counter force. After the armature 6 gradually approaches the electromagnet 5 and the movable contact 3 and the stationary contact 4 are closed, the change rate of the electromagnetic attraction force increases exponentially, at this time, the armature 6 continues to move in an overtravel direction under the attraction force of the electromagnet 5, and because the first spring 11 cannot move, the first spring 11 can only elastically deform under the driving of the armature 6 to press the movable contact 3 and the stationary contact 4, and meanwhile, the second spring 12 is driven to deform towards the deformation adjusting groove 21 and is jointly pressed on the movable contact 3 and the stationary contact 4 together with the first spring 11, so that the change rate of the common counter force of the first spring 11 and the second spring 12 is closer to the attraction force of the electromagnet 5 to the armature 6.

Therefore, electromagnetic attraction force can be well utilized, meanwhile, the movable spring piece can provide enough and stable contact pressure for the movable contact 3 and the fixed contact 4, so that the contact resistance between the movable contact 3 and the fixed contact 4 is reduced, the temperature rise reducing effect is achieved, the ablation risk existing in the disconnection process between the contacts is reduced, and the service life of product switching and the stability of use are improved.

The movable spring piece provided in this embodiment has the structural advantage that under the action of the deformation adjusting groove 21, the second spring 12 deforms towards the space inside the deformation adjusting groove 21, so that the second spring 12 does not need to be processed by a bending process, the processing precision of the groove depth dimension of the deformation adjusting groove 21 is more controllable, the deformation amount generated by the second spring 12 in the deformation process is more convenient to control, and the accuracy of deformation is also improved. The processing difficulty of forming the deformation adjusting groove 21 on the connecting piece structure 2 is low, and the processing cost is reduced, so that the production cost of the whole movable spring piece can be reduced under the condition of improving the production precision.

As shown in fig. 2, the first reed 11 is provided with a receiving opening 13 along a length extending direction L of the first reed 11 from the free end, wherein the receiving opening 13 is disposed in the first reed 11, the second reed 12 is disposed in the receiving opening 13, a dimension of the receiving opening 13 in a width extending direction B is larger than a width dimension of the second reed 12, a side surface of the second reed 12 is not easy to generate contact friction with an inner side surface of the receiving opening 13 in a deformation process, and the second reed 12 is self-reset to the inside of the receiving opening 13 when the deformation is recovered.

Further, the end of the second reed 12 is connected to the first reed 11. As shown in fig. 2, the connection is preferably integrally formed, that is, the first reed 11 and the second reed 12 are integrally formed, for example, the elastic sheet structure 1 forms the first reed 11 and the second reed 12 through a blanking process, so that the elastic sheet structure 1 has good comprehensive properties such as elasticity and structural strength, and the purpose of facilitating the production and manufacturing of the elastic sheet structure 1 is achieved, and the cost for mass production and manufacturing of the elastic sheet structure 1 is greatly reduced.

Please refer to the overall structure schematic diagram of the connecting piece structure 2 in the present utility model shown in fig. 3, the deformation adjusting groove 21 preferably penetrates through the connecting piece structure 2 at both ends, so that the connecting piece structure 2 with the deformation adjusting groove 21 is more convenient to manufacture, the connecting piece structure 2 is also convenient to assemble to the spring piece structure 1, the recognition is not needed, and the foolproof assembly effect of the connecting structure and the spring piece structure 1 is realized.

When the connecting structure assembles the spring plate structure 1, the extending direction of the deformation adjusting groove 21 is consistent with the extending direction of the accommodating opening 13, and when the second reed 12 deforms towards the inside of the deformation adjusting groove 21, the second reed 12 takes one end connected with the first reed 11 as a rotation center, and the free end of the second reed 12 deflects towards the inside of the deformation adjusting groove 21 around the rotation center until the free end of the second reed 12 contacts with the bottom of the deformation adjusting groove 21.

However, the present invention is not limited to the above-described through-connection plate structure 2 at both ends of the strain-adjusting groove 21, and one end of one of the strain-adjusting grooves 21 may not be through-connected. During the assembly of the web structure 2 to the spring structure 1, the end of the deformation adjusting groove 21 which is not penetrated is close to the free end of the first spring 11, so that the free end of the second spring 12 is not blocked during the deflection towards the inside of the deformation adjusting groove 21.

Of course, the spring plate structure 1 can also be welded with the connecting plate structure 2.

As a further preferred solution of this embodiment, as shown in fig. 4 and fig. 1, a connecting section 14 is disposed on a side of the accommodating opening 13 near the free end of the first reed 11, and the connecting section 14 is connected from one side of the accommodating opening 13 to an opposite side of the accommodating opening 13 along the width extending direction of the accommodating opening 13, so as to achieve the purpose of fixedly connecting the connecting section 14 to the first reed 11. Preferably, the connecting section 14 is integrally formed with the first leaf 11.

Specifically, the shape and size of each second reed 12 are preferably the same, and of course, the shape and size of each second reed 12 may be different and the same, for example, in the width extending direction of the accommodating opening 13, the length sizes of the plurality of second reeds 12 gradually increase, and because the length sizes of the plurality of second reeds 12 are different, the time that each second reed 12 acts on the bottom of the deformation adjustment groove 21 is different, then there are more abrupt change turning points of the elastic counter force generated by the second reed 12 along with the change curve of the moving stroke of the armature 6, so that the change rate of the common counter force of the first reed 11 and the second reed 12 is further close to the attractive force of the electromagnet 5 on the armature 6, the utilization rate of electromagnetic attraction can be further improved, and the purposes of reducing the contact resistance and the temperature rise are achieved. Or it is also possible that only a part of the length dimensions of the several second leaves 12 are identical.

Further, a plurality of the above-mentioned second reeds 12 may be the same groove bottom surface that acts together on the deformation regulating groove 21. In addition, the deformation adjusting groove 21 includes a plurality of buffer grooves independently disposed, and each second reed 12 is disposed corresponding to each buffer groove, so that when the second reed 12 deforms, bending deformation is performed towards the corresponding buffer groove.

It should be noted that a plurality of partition structures may be protruded toward the notch of the deformation adjusting tank 21 on the tank bottom of the deformation adjusting tank 21, so as to partition and shape the deformation adjusting tank 21 into a plurality of buffer tanks independently provided.

In this way, the relative distance between the acting surface at the bottom of the deformation adjusting groove 21 and the notch of the deformation adjusting groove 21 will be smaller than the relative distance between the acting surface at the bottom of the sinking groove and the notch of the deformation adjusting groove 21, that is, the relative distance between the acting surface at the bottom of the deformation adjusting groove 21 and the notch of the deformation adjusting groove 21 is defined as the first adjusting pitch, the relative distance between the acting surface at the bottom of the sinking groove and the notch of the deformation adjusting groove 21 is the second adjusting pitch, at this time, the first adjusting pitch is different from the second adjusting pitch, the time when the different second spring pieces 12 act on the corresponding acting surfaces is different, so that more abrupt change points can exist along with the change curve of the moving travel of the armature 6, so that the change rate of the common reaction force of the first spring piece 11 and the second spring piece 12 is further close to the attractive force of the electromagnet 5 on the armature 6, the utilization rate of electromagnetic attraction force can be further improved, and the purpose of reducing the contact resistance and the temperature rise can be achieved.

Therefore, when the second spring 12 on each layer of the first spring 11 is respectively abutted against and contacted with the deformation adjusting groove 21, due to the different distances between the second spring 12 at different height positions and the groove bottom of the deformation adjusting groove 21, more abrupt change turning points exist on the elastic counter force generated by the second spring 12 along with the change curve of the moving stroke of the armature 6, so that the change rate of the common counter force of the first spring 11 and the second spring 12 is further close to the attraction force of the electromagnet 5 to the armature 6, the utilization rate of electromagnetic attraction force can be further improved, and the purposes of reducing contact resistance and temperature rise are achieved.

First, the first reed 11 of the movable reed part is pushed to drive the movable contact 3 to be closed with the fixed contact 4, and when the movable contact 3 is closed with the fixed contact 4, the armature 6 performs over travel movement so as to hopefully continue to push the first reed 11 to move towards the fixed contact 4. However, due to the blocking of the fixed contact 4, the first reed 11 cannot rotate, and can only further elastically deform to press the movable contact 3 and the fixed contact 4, meanwhile, due to the over-travel motion of the armature 6, the second reed 12 of the movable reed member is elastically deformed towards the deformation adjusting groove 21 until the second reed 12 is abutted and pressed at the groove bottom of the deformation adjusting groove 21, so that the resultant force is pressed on the movable contact 3 and the fixed contact 4 through the mutual cooperation of the second reed 12 and the first reed 11, the contact pressure between the movable contact 3 and the fixed contact 4 is ensured, the contact resistance between the movable contact 3 and the fixed contact 4 is reduced, the temperature rise is ensured to be within a certain range, and the service stability and the service life of the relay are effectively improved.
