Embodiment

Please consult Fig. 2 and shown in Figure 3 respectively, button 10 preferred embodiments of the present utility model include a keying body 12, two elastic arms 16 and a holder 14, and housing 20 sides 24 places and the inner bottom surface 22 corresponding with it at an electronic installation is respectively equipped with a slotted eye 242 and most positioning convex rods 222 in addition; Make button 10 to be fixed on the positioning convex rod 222, and keying body 12 can be positioned among the slotted eye 242 simultaneously, with the housing 20 sides 24 inner edge places that are mounted on above-mentioned electronic installation via holder 14.

Please consult Fig. 4 and Fig. 5 respectively, the periphery of these keying body 12 inboards has a chimb 122, and have a protrusion at keying body 12 back sides and generally be the criss-cross portion 124 that presses, the peripheral region of keying body 12 inboards extends the above-mentioned corresponding paired elastic arm 16 of connection in addition, it is one rectangular-shaped that elastic arm 16 outward appearances bendings is, and elastic arm 16 bottom end then are connected with the peripheral region of these holder 14 outer side edges, make keying body 12 surface be a mutual perpendicular shape, the then spaced apart detent 142 that is provided with majority of holder 14 inner side edges of position is set corresponding to elastic arm 16 in addition with holder 14 surfaces.

Button 10 of the present utility model mainly is by holder 14, be mounted on the housing 20 inner edge places of electronic installation, wherein holder 14 side edge places offer two detents 142, can be in order on the positioning convex rod 222 set on the inner bottom surface 22 that is fastened in case of electronic device 20, and keying body 12 is positioned among the slotted eye 242 of housing 20 sides 24 simultaneously; Program when wherein this button 10 is installed on the housing 20 of electronic installation, please consult simultaneously shown in Fig. 7 A and Fig. 7 B, at first, with the detent on the holder 14 142, aim at and be fastened on the positioning convex rod 222 set on the inner bottom surface 22 of case of electronic device 20, moreover, by downward pressing keys body 12, make elastic arm 16 be able to side direction bending in housing 20, so can make keying body 12 can be arranged in slotted eye 242 inside smoothly, and be positioned among this slotted eye 242, as shown in Figure 5; Because 14 elastic arms that are connected 16 of keying body 12 of the present utility model and holder have elastic force, so can make when keying body 12 is arranged in the slotted eye 242, keying body 12 can be born the resilience strength of elastic arm 16 and is close to the inboard peripheral surface of slotted eye 242, holder 14 then can afford the resilience strength of elastic arm 16 and component with the keying body of being away from 12 directions equally simultaneously, so can make stably to be fastened in one between detent 142 and the positioning convex rod 222 of holder 14 and to be difficult for breaking away from, do not fix and do not need in addition again to make positioning convex rod 222 and detent 142 melt processing mode such as mode by glue via secondary operations.

Other sees also shown in Figure 6, button 10 of the present utility model mainly is to make in integrally formed mode, the feasible elastic arm 16 that is connected between keying body 12 and the holder 14 has the elastic force of an appropriateness, as user during by the outside pressing keys body 12 of housing 20, this keying body 12 promptly can elastic arm 16 the bending place be that fulcrum is rearward retired, make the portion that presses 124 at keying body 12 back sides be touched the switch (not icon) on the housing 20 inner set circuit boards (not icon), reach the effectiveness of open-close on-off; Stop pressing keys body 12 and work as the user, keying body 12 is lost when being subjected to this pressing force, keying body 12 can be subjected to the strength of elastic arm 16 resiliences, and keying body 12 involutions are moved to its original position.

As shown in the above description, the utility model is the holder 14 of button 10 is designed in orthogonal mode with keying body 12, and offer most detents 142 corresponding to holder 14 another opposite side that elastic arm 16 is provided with the position, make when button 10 is mounted on the housing 20, the component that holder 14 can have the keying body of being away from 12 directions by the resilience strength of elastic arm 16, make between the detent 142 of holder 14 and the positioning convex rod 222 and can stably be fastened in one, and do not need to be fixed again by the mode of secondary operations more in addition, time in the time of not only can saving the product assembling, expense in the time of more can saving secondary operations, and have huge economically benefit.

Though the utility model discloses with specific embodiment; but it is not in order to limit the utility model; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.
