Abstract

The utility model relates to a tactile switch, comprising an insulation body, a plurality of fixed connection points arranged in the insulation body and a movable connection point, an actuating component and a cover body orderly assembled on the insulation body, wherein, the cover body is provided with an elastic clip raised downwards which brakes in cooperation with the actuating component, while the movable connection point is provided with a plurality of convex parts raised downwards which contact or separate with the fixed connection point. When in use, the switch pushes the actuating component to move downwards in pressure of the elastic clip on the cover body, and then deforms the movable actuating component, making the raised part on the movable connection point move downwards to realize electric communication with the fixed connection point, then releases the actuating component, performing the electric cut between the movable connection point with the fixed connection point by use of the elastic recover force, and thus the switch function is realized. As the downwards raised part of the movable connection point, the utility model can realizes the stable electric contact with the fixed connection point in comparatively little deformation of the movable connection point, thereby shortening the reaction time of the tactile switch and promising reliable operation.

Description

The actuating type switch

[technical field]

The utility model relates to a kind of actuating type switch, refers in particular to a kind of actuating type switch that is used for portable electron device.

[background technology]

The prior art relevant with the utility model please refer to shown in No. the 2572590th, the Japanese Utility Model patent, the actuating type switch that it disclosed comprises insulating body, be fixed on insulating body fixed bottom, be arranged on the movable terminal of fixed terminal top, actuator and lid, wherein lid is provided with an elasticity oblique plate, the press section that actuator is provided with the Actuator Division between elasticity oblique plate and movable terminal and protrudes from the base side wall that insulate, during use, activate the press section of actuator, described Actuator Division compresses described movable terminal under the effect of oblique plate, thereby make movable terminal distortion and the conducting that contacts with fixed terminal with its below, when unclamping, movable terminal disconnects with fixed terminal under the effect of elastic restoring force, and then makes the actuating type switch finish switch motion.Yet, distance is bigger between the movable terminal of this existing actuating type switch and the fixed terminal, need to produce the moderate finite deformation amount after movable terminal is stressed and just can contact with fixed terminal, thus this actuating type switch not enough or movable terminal generation elastic fatigue produces the defective of poor flow because of pressing force easily.In addition, bigger distortion can take place in above-mentioned movable terminal in course of action, and this can make the electronic installation reaction time of using this actuating type switch long and be unfavorable for operation readiness.

[utility model content]

The actuating type switch that the utility model purpose is to provide a kind of stable performance and is convenient to operate.

The purpose of this utility model is achieved through the following technical solutions: the utility model touch switch comprises insulating body, be arranged on the plurality of fixed contact in the insulating body and be assembled in travelling contact, actuator, lid on the insulating body successively, wherein lid convexes with the shell fragment of braking in order to cooperate with actuator downwards, and described travelling contact convexes with the some protuberances that contact or separate with fixed contact downwards.

Compared with prior art, the travelling contact of actuating type switch of the present utility model convexes with protuberance downwards, this can make travelling contact under less deflection can with stable being electrically conducted of fixed contact, and help shortening reaction time of touch switch, be convenient to operation.

[embodiment]

Please refer to illustrated in figures 1 and 2ly, the utility model actuating type switch 1 comprises insulating body 10, be arranged on the fixed contact 20 in the insulating body 10 and be assembled in travelling contact 30, actuator 40, lid 50 on the insulating body 10 from bottom to top successively.

Insulating body 10 roughly is the box-shaped of top opening, comprises that diapire 11 reaches antetheca 12, rear wall 13, the two side 14 that extends upward setting around diapire 11.Wherein diapire 11 two ends are provided with stepped higher first step 15 and lower second step 16, antetheca 12 and rear wall 13 at 14 places, contiguous two side respectively all symmetry be concaved with first groove 17, on the sidewall 14 then symmetry be concaved with second groove 18.In addition, described front and

back walls

12,13 mid portions are provided with breach (not label).

Fixed contact 20 is arranged in insulating body 10 diapires 11, comprise that the surface exposes the contact site 21 and the weld part 22 of insulating body 10 diapires 11 inner surfaces, weld part 22 protrudes out insulating body 10 both sides in order to actuating type switch 1 is welded on the electronic device circuit plate (not shown).

Travelling contact 30 is provided with top 31 and is the sidepiece 32 that the certain slope bending is extended from the top around 31.Wherein top 31 dashes downwards and is provided with a plurality of protrudingly 33, and in the present embodiment, projection 33 is four, as required one or more projectioies can be set certainly.

Actuator 40 is provided with movable part 41 and is located at insulating body 10 press section 42 outward.Wherein movable part 41 is provided with guidance part 43, the Actuator Division 45 that is provided with is extended by fluting 44 self-pressing portions 42 in fluting, and Actuator Division 45 front ends are the inclined-plane setting.

Lid 50 is provided with main part 51, autonomous body 51 vertical both sides bend the fixing pin 52 of extension and the retaining sheet 53 that autonomous body 51 both lateral sides bend extension downwards downwards, and wherein main part 51 middle parts are also downwards towards being provided with a shell fragment 54 that roughly is " V " type.

During assembling, travelling contact 30 transverse ends are placed on the second step 16 at insulating body 10 diapires 11 two ends, and its top 31 does not contact with fixed contact 20 contact sites 21, movable part 41 transverse ends of actuator 40 are placed on the first step 15 at insulating body 10 diapires 11 two ends, and 50 of last lids match with second groove 18 on the insulating body 10 by first groove 17 on fixing pin 52 and the insulating body 10 and retaining sheet 53 and are assembled on the insulating body 10 and fix travelling contact 30 and actuator 40 between insulating body 10 and lid 50.The Actuator Division 41 of actuator 40 is positioned between " V " shape shell fragment 54 and the travelling contact 30.
