Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the sectional exploded view of the utility model embodiment one;
Fig. 2 is the sectional exploded view of the utility model embodiment two;
Fig. 3 is the three-dimensional explosive view of part embodiment illustrated in fig. 2.
The specific embodiment
Embodiment one:
As shown in Figure 1, the sectional exploded view of the utility model embodiment one.
The hermetically-sealed construction of this head lamp button has a loam cake 10, and the top board of this loam cake 10 has a through hole 11 that runs through, and through hole 11 belows have the upper flange 12 towards downward-extension; In the periphery of upper flange 12, has the upper annular groove 13 of depression up;
Other has a flexure strip 20, adopts flexible material to make, and the central authorities of its upper surface have a convex platform 21, and the periphery of convex platform 21 has the annular groove once 22 towards lower recess, and this time annular groove 22 peripheries have the lower convex ring 23 of projection up.The level cross-sectionn of through hole 11, flexure strip 20 is circle.
As seen, loam cake 10, flexure strip 20 and touch-switch have been set up a switch hermetically-sealed construction, from loam cake 10 outsides flexure strip 20 are carried out pressing operation, and directly transfer function power is in the movable switch position 31 of touch-switch 30, and switching manipulation is directly reliable; On the other hand, adopt cooperating of two-stage annular groove and flange between flexure strip 20 and the through hole 11, obtained good sealing effectiveness, accessory is few, simple in structure simultaneously.
Embodiment two:
As shown in Figures 2 and 3, the schematic diagram of the utility model embodiment two.
Such as Fig. 2, the through hole 11 of present embodiment, shell fragment 20 and touch-switch 30 are similar with embodiment one, and the cooperation form of its annular groove and flange is also similar.
In the present embodiment, flexure strip 20 belows also have a support ring 50; Touch-switch 30 is fixed in base plate 40 simultaneously, and support ring 50 surrounds touch-switch between base plate 40 these flexure strip 50 lower surface peripheries.This support ring can increase the effective travel that flexure strip 20 is pressed, and can save the material that base plate 40 is used for extruding flexure strip 20.Also has a support edge 41 up in the present embodiment on the base plate 40, this support edge 41 surrounds touch-switch 30, and its top is matched with the bottom surface of support ring 50, and this support edge 41 further provides the support to flexure strip 20 lower surface peripheries, also can position touch-switch 30.Set firmly down a salient point 24 at flexure strip 20 lower surfaces, this salient point 24 cooperates with the movable switch position 31 of touch-switch 30, makes pressing of 20 pairs of movable switch positions 31 of flexure strip more reliable.
