Embodiment
below in conjunction with accompanying drawing, the specific embodiment of the invention is described.
Embodiment
a kind of contact spring, is combined by housing, plane spring body and end plate.
the structure of spring body as shown in Figure 1, spring body 10 is formed by stamped metal sheets, spring body 10 comprises bend 11, bend 11 is S type, the upper end of bend 11 is connected with contact plate 12, lower end connects lower contact jaw 13, contact plate 12 can be provided with two upper contact jaws 121 also can arrange one, upper contact jaw 121 is preferably trapezoidal, bend 11 is connected with the middle part of contact plate 12, and contact plate 12 1 side is provided with salient point 122, and the both sides, lower end of contact plate 12 are provided with guide vane end stop 123, move for Restricted Contact plate 12, prevent from exceeding elastic deformation.Lower contact jaw 13 is arranged on left side or the right side of spring body 10, and lower contact jaw 13 is provided with bayonet socket 131, and the lower end of bend 11 is provided with location hole 132, and both sides are provided with block 14, for being limited in housing 20 by spring body 10.
the structure of housing and end plate as shown in Figure 2,3, 4, the concave surface placing spring body 10 is provided with in housing 20, one end of housing 20 offers the chute 21 slided for salient point 122, the projection 22 coordinated with the location hole 132 of spring body 10 is provided with in housing 20, housing 20 two ends are provided with joint pin 23, for housing 20 stacked combination, housing 20 upper end is provided with the upper groove 24 coordinated with guide vane end stop 123, the elastic force of neglecting greatly bend of groove 24 and determining, housing 20 lower end is provided with the low groove 25 coordinated with block 14.End plate 30 both sides are provided with the joint pin coordinated with housing 20, are placed on least significant end, fix in case anti-avulsion goes out.
