Embodiment
A kind of face contact spring, the left deformed plate 11 that comprises contact plate 2, be connected with the left end of contact plate 2, the right deformed plate 12 being connected with the right-hand member of contact plate 2, described left deformed plate 11, contact plate 2 and right deformed plate 12 are integrative-structures, the bending of upwards turning back of the free end of left deformed plate 11, the bending of upwards turning back of the free end of right deformed plate 12.Contact plate 2 adopts circular arc excessive with the junction of deformed plate, to strengthen the intensity of face contact spring.
As shown in Fig. 2,5, the free end of left deformed plate 11 is bending to the right, and the free end of right deformed plate 12 is bending left, and the free end of left deformed plate 11 does not contact mutually and do not contact with contact plate 2 with the free end of right deformed plate 12.Left deformed plate 11, contact plate 2 and right deformed plate 12 form " C " shape structure.Two deformed plates projection sum and contact plate 2 length ratios on contact plate 2 are less than 2/3.
As shown in Fig. 3,6, the free end of the free end of left deformed plate 11 and right deformed plate 12 is all bending to contact plate 2 and contact with contact plate 2, and the free end of the free end of left deformed plate 11 and right deformed plate 12 can contact with each other, and also can not contact.Left deformed plate 11, contact plate 2, right deformed plate 12 form " B " shape structure.Two deformed plates projection sum on contact plate 2 is slightly less than contact plate 2 length.In the time of compressing deformed plate, the free end of left deformed plate and the free end of right deformed plate can, along contact plate generation micro-displacement, therefore can be designed to comparatively round and smooth structure by the free end of deformed plate, to reduce friction.
As shown in Fig. 4,7, the free end of left deformed plate 11 is bending to the right, and the free end of described right deformed plate 12 is bending left, and the free end of the free end of described left deformed plate 11 and right deformed plate 12 is overlapping up and down.Left deformed plate 11, contact plate 2, right deformed plate 12 form " D " shape structure.The free end of the free end of left deformed plate 11 and right deformed plate 12 is overlapping up and down, can contact with each other, and also can not contact.
A kind of distressed structure of the present invention, as shown in Figure 8, deformed plate waviness.
When use, deformed plate is spacing by fixed cover 5, and external force can make deformed plate elastic force everywhere inconsistent, thereby makes deformed plate one side distortion large, and opposite side distortion is little, and the surface contacting with deformed plate on fixed cover 5 exists certain angle with respect to contact plate 2.
Preferably, on the dual-side that the link of deformed plate and contact plate 2 is adjacent, be provided with breach 3.Breach 3 is arc notch 3 or square breach 3 or rectangular indentation 3 or vee 3 or other shapes, as shown in Fig. 9,10.The setting of breach 3, does not affect the distortion of deformed plate, and the contact plate 2 that has simultaneously reduced deformed plate and contactant is long-pending, makes the surface contacting with deformed plate on fixed cover 5 can form larger deflection angle with respect to contact plate 2.When spacing to deformed plate, can select less fixing outer box, cost-saving, reduce volume.
As shown in figure 11, on deformed plate, be provided with projection 7, also can play the effect identical with breach 3.Projection 7 and breach 3 also can exist simultaneously.
The resistant to elevated temperatures metal material of the preferential selection of material of face contact spring.
Figure 12 is that face contact spring is applied to the structural representation in socket, socket comprises contact 4, the outside of contact 4 is provided with face contact spring, the contact plate 2 of face contact spring is suitable with contact 4 surfaces, the deformed plate of face contact spring is spacing by fixed cover 5, in the time that plug 6 inserts between two contacts 4, contact 4 surfaces contact well with the contact plate 2 of face contact spring, and to face contact spring deformed plate exert pressure, the deformed plate cover that is fixed is 5 spacing, reaction makes contact plate 2 compress contact 4 to contact 4 elastic force, and contact 4 clamps plug 6.On the adjacent dual-side of the link of deformed plate, be provided with breach 3, simultaneously, the lower end of contact 4 can not fixed, can make deformed plate with respect to fixed cover 5 deflections, thereby make contact plate 2 have certain deflection, the lower end of contact 4 is fixing, therefore contact 4 also can deflection, avoid plug 6 situation that cause because of fabrication error and socket loose contact, therefore can adapt to various types of plugs 6.
