The inverted switch is arranged on a circuit board via the fixing leg and the output terminal, to enable the button be face to face with the circuit board and is raised to trigger via a trigging mechanism on a lower portion.

Description

The handstand switch

Technical field

The utility model relates to a kind of electronic original part, and especially a kind of setting is in the circuit board to avoid the novel switched of misoperation.

Background technology

Electronic product is integrated more and more higher at present; usually can on a wiring board, be integrated with many switch elements; and by a component controls; as shown in Figure 1; the four-axis centre wheel module left and right sides page turning switch of existing mouse inside, middle key switch adopt common following compressing switch, and directly are welded on the mouse bottom plate (PCB), touch left and right sides page turning by the module left and right sides haptic element bottom; press down key switch in the shake-up by centre wheel, be easy to cause when pressing down like this about the misoperation of page turning switch.Perhaps be contained on another piece wiring board, and,, use conducting circuits such as connector, and design complicated shake-up system and touch from following by fixed positions such as screws with the wiring board reversing with compressing switch under common, complex structure, with high costs, make difficult.

Summary of the invention

The purpose of this utility model is easily to produce misoperation at the operating process that existing control switch exists, cause deficiencies such as circuit board structure complexity simultaneously, provide a kind of simple in structure, parts are few, life-span is long, assembling easily, and is with low cost and can effectively avoid producing in the use the novel handstand switch of misoperation.

The technical solution of the utility model is: a kind of handstand switch, and described handstand switch is by base, pot shape shell fragment, and button and cover plate are formed, and pot shape shell fragment is installed in the base, and lead-out terminal stretches out from base top; Pot shape shell fragment edge contacts with base intracavity both sides metal salient point, and the middle part projection of pot shape shell fragment is unsettled; Button is installed in pot shape shell fragment top, and the button internal cavities is provided with the button of a soft body; The cover plate upper design has fixing feet, and the bottom is fixed on the base with the button pin, and this handstand switch is installed on the circuit board by fixing feet and lead-out terminal, makes button relative with wiring board, and triggers office by the below and lift triggering.

Preferably, lead-out terminal and fixing feet are provided with the reinforcement that strengthens anti-folding degree.

The beneficial effects of the utility model are: should the handstand switch application on the wiring board of mouse inside, the function that makes left and right sides page turning no longer by under the realization that compresses switch, but upwards touch the realization of handstand switch by waving support, opposite with the stroke that compresses switch under the centre, thoroughly avoided misoperation, with respect to adopting regular tap to be contained in another piece wiring board upset implementation, the utility model is simple in structure, easy to manufacture, with low cost.

Embodiment

As Fig. 1 and Fig. 3, first specific embodiment of the present utility model shown in Figure 4, a kind of handstand switch is by base 13, pot shape shell fragment 14, and button 15 and shell 16 are formed, and a pot shape shell fragment 14 is installed in the base 13, and lead-out terminal 11 stretches out from base 13 tops; Pot shape shell fragment 14 edges contact with base 13 inner chamber both sides metal salient points 17, and the middle part projection of pot shape shell fragment 14 is unsettled; Button 15 is installed in pot shape shell fragment 14 tops, and button 15 internal cavities are provided with a soft body 18; Shell 16 4 apertures 19 alignment bases 13 4 riveting posts 20 put and rivet; The shell upper design has fixing feet, and the bottom is fixed on the base with button pin 22.Lead-out terminal 11 and fixing feet 12 are provided with the reinforcement 21 that strengthens anti-folding degree.Wherein fixing feet 12 is arranged on two adjacent limits of lead-out terminal 11.

The mouse four-axis centre wheel module that this handstand switch is installed as shown in Figure 2, comprise the encoder components 1, centre wheel 2, the mouse wiring board 7 that are used for the output encoder pulsed electronic signal, encoder components 1 is enclosed within on the central shaft of centre wheel 2, in the draw-in groove of mouse wiring board 7, be provided with one and wave parts 3, the two ends of waving parts 3 are respectively arranged with back shaft 35 and back shaft 36, two back shafts and are installed on the bracing frame 71 and bracing frame 72 on the mouse wiring board 7; The both sides of waving parts 3 are provided with draw-in groove 32,33 centre wheel 2 are held, and encoder 1 is installed in and is arranged in the square groove 31 that waves parts one side; Waving parts 3 tail ends is provided with roller and presses down key switch haptic element 38,7 are provided with roller and press down key switch 4 on the mouse wiring board of its below, the both sides of waving parts 3 front ends are respectively equipped with switch haptic element 36 and switch haptic element 37, and the contact of two switch haptic elements upwards, be provided with respectively on handstand switch 5 and handstand switch 6, the two handstand switches in the position of switch haptic element and be connected with mouse bottom plate (PCB) with fixing feet by lead-out terminal.

When centre wheel 2 is swung to the right, the left-side switch haptic element 37 that waves parts 3 up moves, and contacts handstand switch 5 output make-and-break signals with handstand switch 5 buttons on the Genius mouse wiring board, by the reverse graft method of circuit in the wiring board, realize moving right or stirring of form; When centre wheel 2 is swung left, the right-side switch haptic element 36 that waves parts 3 up moves, and contacts handstand switch 6 output make-and-break signals with handstand switch 6 buttons on the Genius mouse wiring board, by the reverse graft method of circuit in the wiring board, realize moving left or stirring of form; When pressing centre wheel 2 instantly, make and wave parts 3 rollers and press down key switch haptic element 38 and press down, the roller of separating on the Genius mouse wiring board presses down key switch 4, realizes the middle key function of Genius mouse, and after unclamping, Genius mouse four-axis centre wheel module utilizes spring 8 returns.
