One embodiment of a movable contact spring structure is presented with respect to fig. 1-3.
The movable reed structure comprises an armature piece 1, an insulating piece 2, an elastic piece 3 and a movable point piece 4.
Specifically, the armature member 1 has a flat plate structure, the insulating member 2 is connected between the armature member 1 and the elastic member 3, the moving point member 4 is connected to the elastic member 3, and the moving point member 4 is provided with the moving contact 41. And preferably, the insulator 2 is attached to the bottom of the armature member 1, and the elastic member 3 is attached to the bottom of the insulator 2. And it is also preferable that the elastic member 3 is attached to the insulating member 2 at an intermediate position.
And preferably the armature element 1 can be selected from iron-machined parts. And it is also preferable that the insulator 2 be selected from plastic, rubber, silicone, etc. processed parts; and, the insulator 2 may be connected to the armature by a bolt; alternatively, the insulating member 2 may be connected by rivets; alternatively, the insulator 2 may be clamped to the armature by a clamping block. And also preferably, the elastic member 3 may be a member formed by processing conductive metal, for example, stainless steel; or, selecting conductive metal to process to form a sheet structure, such as a spring sheet; and, the bottom of the insulator 2 to which the elastic member 3 is attached means an end of the insulator 2 away from the armature member 1. And also preferably, the moving point 4 may be a part machined from conductive metal, such as copper. And also preferably, the movable contact 41 may be a member machined from a conductive metal, such as a silver alloy.
Also, the elastic member 3 and the insulating member 2 may be integrally formed, for example, manufactured using an integral injection molding process. Alternatively, the elastic member 3 and the insulating member 2 are fixedly connected, for example, by riveting, bonding, keying, pinning, or the like.
According to the present embodiment, when the movable reed structure is in use, current will flow through the movable contact 41 and the movable point member 4, so that the elastic member 3 will have electromotive force, in order to prevent the armature member 1 from being electrified to affect the safe use, the movable reed structure is provided with the insulating member 2 between the armature member 1 and the elastic member 3, and the insulating member 2 can isolate the electromotive force carried on the elastic member 3 to prevent the armature member 1 from being driven; and, the setting of insulating part 2 can also increase the interval between armature piece 1 and the elastic component 3 to reach the effect that increases creepage distance and electric gap, guarantee the safe handling of relay. Meanwhile, the armature piece 1 is of a flat plate structure, the armature piece 1 does not need to be bent, and the distance between the armature piece 1 and the elastic piece 3 can be further increased by combining the insulating piece 2, so that the effect of increasing the creepage distance and the electric gap is achieved.
More importantly, the armature and the spring are also integrally formed by the injection molding process, however, when injection molding is carried out, the armature and the spring are required to be prevented from being placed on an injection mold, so that two models of the armature and the spring are required to be opened on the injection mold, and the mold difficulty and the manual placement cost of the mold opening are increased. In the movable reed structure in the embodiment of the utility model, the armature piece 1, the insulating piece 2 and the elastic piece 3 are independently manufactured and then assembled, so that an injection molding process is not required, the structure is simple, the assembly is easy, and the labor cost can be effectively reduced.
According to fig. 1 to 3, in particular, in order to better prevent the armature element 1 from being charged, the insulator element 2 and the armature element 1 are connected by a locking element 5. And preferably, the insulator 2 and the armature member 1 are connected by a pair of locking members 5, wherein the insulator 2 is disposed between the pair of locking members 5. In other words, a pair of locking members 5 are provided on both sides of the insulating member 2. And preferably, the locking member 5 may be a rivet; alternatively, the locking member 5 may be a bolt.
According to this embodiment, this movable reed structure can have electromotive force on the elastic component 3 when using, because retaining member 5 connects between armature piece 1 and insulating component 2, retaining member 5 self can select the part that conductive metal formed, therefore retaining member 5 also can have electromotive force when too near from elastic component 3, and then make armature piece 1 electrified, consequently set up a pair of retaining member 5 in the both sides of insulating component 2, make retaining member 5 far away from elastic component 3, increase creepage distance and electric gap under the unchangeable circumstances of volume and power.
More importantly, the insulating piece 2 and the armature piece 1 in the movable reed structure are riveted through rivets, so that the insulating distance and creepage clearance between the armature piece 1 and the elastic piece 3 are improved by changing the riveting position, and the safe use of the relay is ensured.
According to fig. 1 to 3, and preferably, the insulator 2 has a convex shape, the insulator 2 includes an insulator coupler 21 and an insulator body 22 integrally formed, the insulator coupler 21 and the armature member 1 are coupled by a pair of locking members 5, and the insulator body 22 is disposed between the pair of locking members 5. And preferably, the insulating main body member 22 is connected to the middle of the insulating connecting member 21, the insulating connecting member 21 has a length H1 along the length direction, and the insulating member 2 has a length H2 along the length direction, wherein H2 < H1. Since the self length H2 of the insulating main body member 22 is smaller than the self length H1 of the insulating connecting member 21, which corresponds to the space positions where the locking members 5 are mounted in advance on both sides of the insulating main body member 22, when the locking members 5 are mounted between the insulating connecting member 21 and the armature member 1, the locking members 5 do not interfere with the insulating main body member 22, and the normal assembly and use of the present movable reed structure can be ensured. And preferably, the thickness of the insulating main body member 22 itself is greater than that of the insulating connecting member 21 itself, so that the locking member 5 can be further away from the elastic member 3, and the creepage distance and the electric gap can be increased without changing the volume and the power, wherein the length direction, the width direction and the thickness direction described in the specification can be specifically referred to fig. 1.
According to fig. 1-3, and preferably, the elastic member 3 is arranged in the middle of the insulating member 2, the elastic member 3 having a length H3 along the length direction, wherein H3 < H2. Thus, the locking member 5 is further from the elastic member 3, and the creepage distance and the electric clearance are increased under the condition of constant volume and power.
The embodiment of the utility model provides a movable reed structure and a relay comprising the movable reed structure.
According to fig. 1-3, further, in order to ensure complete centering of the movable contact and the stationary contact at all times during the instant of contact and complete contact, the angle α between the armature element 1 and the elastic element 3 is set to be: alpha is more than or equal to 80 degrees and less than 90 degrees, and alpha is more than or equal to 90 degrees and less than or equal to 96 degrees. And in particular, the included angle α may be 80 °, 82 °, 84 °, 86 °, 88 °, 92 °, 94 °, or 96 °. And preferably the angle α=88°, at which the life of the moving and stationary contacts is the longest over a number of experiments.
According to the present embodiment, since in the relay of the prior art, an engineer usually takes the state that the movable contact and the stationary contact are in close contact as the final state of the product, in order to ensure that the movable contact and the stationary contact can be completely centered in the close contact state, the armature and the spring are usually arranged in a spatial vertical structure, however, in such a vertical structure, the movable contact and the stationary contact cannot be completely centered in the state of just contacting. Therefore, when the relay works, the electric arc generated when the movable contact and the fixed contact just contact is not at the centers of the movable contact and the fixed contact, and the service lives of the movable contact and the fixed contact can be reduced to a certain extent.
In view of this, by forming a non-perpendicular structure between the armature member 1 and the elastic member 3, the movable contact and the stationary contact can be always ensured to be completely centered at the moment of just contact and in the process of complete contact through the included angle, so that an arc is generated between the movable contact and the stationary contact, and the service lives of the movable contact and the stationary contact are prolonged.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
