Abstract
A kind of frivolous 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; The contact that the conductive film is corresponded in the elastic element is equipped with conductive stud grain; The elastic element is connect with keycap cementation. 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 frivolous 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 frivolous key device, and its conductive film is single thin slice, 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 frivolous 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; Contact that should conductive film is provided with the conductive stud grain in this flexible member; This flexible member is connected with the keycap cementation.
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; Except that its contact, locate to be coated with insulation film on this conductive film; 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 change single thin slice into, and corresponding button is provided with on it by traditional two or three folded mutually establishing
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 coated with one deck insulation film 23 on conductive film 2, protects its circuit, prevent to be touched, but its
Insulation film 23 is not plated at shape contact 21 places.Its flexible member 3 is bowl-shape, in be provided with conductive stud grain 31, which is provided with the contact 21 conducting loops of the corresponding and conductive film 2 of conflicting of conductive layer 311, between flexible member 3 and keycap 5, pass through non-reacted viscose glue 6 cementations, so keycap 5 can the repeated multiple times disassembly and assembly, use more convenient.
Consult Fig. 4, assembling method of the present utility model is the contact 21 peripheral places that the big bowl mouth end of the external diameter of flexible member 3 contacts at conductive film 2, 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 6 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.
