Abstract
A kind of follow-on key device, successively installs conductive film, elastic element, bridge formation and keycap on bottom plate, it is characterised in that: the conductive film be single flake, correspond to thereon each key be equipped be in
The contact of shape, conductive film top are equipped with transparent insulation piece, and the contact which corresponds to the conductive film forms aperture; The contact that the conductive film is corresponded in the elastic element is equipped with conductive stud grain; The both ends of the elastic element are connect with cementation above the aperture of keycap and transparent insulation piece respectively. The present apparatus has the advantages that key is frivolous, conducting is smooth and pressing is brisk.
Description
The utility model relates to by strong, refers in particular to a kind of follow-on key device.
The conductive film of button commonly used is generally established correspondence and is combined by two or three films are folded mutually, and its major defect is: whole button is higher, and it is more to consume material; And wherein the generation of a slice film is crooked, with causing the contact on each film not align, causes poor flow.
The purpose of this utility model is to provide a kind of follow-on key device, and its conductive film is single laminar, and its corresponding button place is provided with
The shape contact is provided with corresponding and this contact of conflicting of conductive stud grain and forms conducting loop in the flexible member, reach the frivolous and conducting of button purpose smoothly.
The purpose of this utility model is achieved in that a kind of follow-on key device, installs conductive film, flexible member, bridge formation and keycap on base plate successively, it is characterized in that: this conductive film is single laminar, and corresponding each button is provided with and is on it
The contact of shape, this conductive film top is provided with the transparent insulation sheet, and this transparent insulation sheet forms perforate to contact that should conductive film; Contact that should conductive film is provided with the conductive stud grain in this flexible member; The two ends of this flexible member are connected with the perforate top cementation of keycap and transparent insulation sheet respectively.
Be provided with the perforation of cooling down in the middle of the contact of this conductive film; This flexible member and keycap are by non-reacted viscose glue cementation; The cementation place of this flexible member and keycap is provided with air-vent; On the conductive stud grain of this flexible member contact place that should conductive film is provided with conductive layer.
Major advantage of the present utility model is:
1, its conductive film is by traditional two or three folded mutually establishing, and changes into single laminarly, and corresponding button is provided with on it
The shape contact makes button frivolous, saves material and reduces cost, and make conducting smooth and easy.
2, at the contact place of conductive film and the cementation place of flexible member and keycap, respectively be provided with air-vent, have and push brisk advantage smoothly.
3, between flexible member and strong cap with non-reacted viscose glue cementation, be convenient to repeatedly disassembly and assembly.
The utility model is further specified as follows below in conjunction with drawings and Examples:
Fig. 1 is a button perspective exploded view of the present utility model;
Fig. 2 is a conducting membrane structure schematic diagram of the present utility model;
Fig. 3 is an elastic element structure schematic diagram of the present utility model;
Fig. 4 is an assembled state structural representation of the present utility model (broken section).
Consult Fig. 1-Fig. 3, the same base plate 1, bridge formation 4 and the strong cap 5 of being provided with of button 10 of the present utility model with common technology, its improvement part comprises conductive film 2 and flexible member 3, and its conductive film 2 is single thin slice, and corresponding each button 10 is provided with and is on it
The contact 21 of shape is provided with the perforation 22 of cooling down in the centre of contact 21, is provided with the insulating trip 6 of layer of transparent on conductive film 2, protects its circuit, prevent to be touched, but its correspondence
Consult Fig. 4, assembling method of the present utility model is perforate 61 tops that the big bowl mouth end of the external diameter of flexible member 3 adheres to the transparent insulation sheet 6 of conductive film 2 tops, makes conductive stud grain 31 just over against being
On the contact 21 of shape, the external diameter of flexible member 3 passes through non-reacted viscose glue 7 and keycap 5 cementations than small end.In the use, when keycap 5 was pressed, promptly can the conflict contact 21 of conductive film 2 of the conductive layer 311 of the conductive stud grain 31 in the flexible member 3 formed the conducting loops, and press signal is sent in the host computer.Be step shape at the cementation place of flexible member 3 and keycap 5 and form air-vent 32, when flexible member 3 presses down, its inner air is flowed out by the perforation 22 of cooling down in the middle of the conductive film 2, when the downforce of going to disappear is loosened flexible member 3, air flows in the flexible member 3 from air-vent 32, reinstatement is waited for and being pushed once more, makes pressing operation brisk smooth and easy.
