Description
Technical field
The utility model relates to a kind of computor-keyboard member, particularly a kind of computor-keyboard thin film switch structure.
Background technology
Along with the progress of electronics technology, keyboard of notebook computer presents lightening trend, and this just needs also attenuation thereupon of keyboard.The cooperation that present most keyboard all will have button and press rubber just can be finished function, if do not press the cooperation of rubber, strain can not take place keycap itself, so button can not touch conductiving point, makes keyboard finish function.But because it is thicker to press the thickness of rubber, cause key stroke longer, the thickness of keyboard is thicker, is subjected to its structure influence, and it is thinner that the keyboard of this structure can not be done.
Summary of the invention
The utility model provides a kind of computor-keyboard thin film switch structure, and purpose is to solve the prior art problem, provides a kind of overall structure thin thin film switch structure.
The utility model technical scheme that adopts of dealing with problems is:
The computor-keyboard thin film switch structure, include the plastic film layers as bottom, be provided with circuit layer, insulating barrier, key cap layer on the plastic film layers upper surface successively, be printed with several conductiving point a to mutual separation, conductiving point b at plastic film layers, every pair of corresponding keycap of conductiving point a, conductiving point b; Wherein the position of the corresponding conductiving point a of circuit layer and insulating barrier, conductiving point b is equipped with cavity, is provided with elastic conducting layer between electricity point a, the conductiving point b of keycap and correspondence.
Described elastic conducting layer is conductive rubber layer, and conductive rubber is placed on the insulating barrier upper surface; Between conductiving point a and the conductiving point b, between conductiving point a and the circuit layer, be respectively equipped with insulating barrier between conductiving point b and the circuit layer.
Described elastic conducting layer is the pressure-sensitive conductive rubber layer, and this pressure-sensitive conductive rubber layer passes the insulating barrier cavity and places conductiving point a, conductiving point b upper surface, directly contacts with conductiving point a, conductiving point b.
Further, the feel when pressing in order to improve button is provided with a shell fragment between pressure-sensitive conductive rubber layer and keycap.
The beneficial effects of the utility model: the computor-keyboard among the application is by the improvement of structure, conductiving point is arranged on the plastic film, and with rubber-like conductive rubber or pressure-sensitive conductive rubber as conductive layer, rubber and conducting wire have been replaced pressing, replace original double-layer structure with one deck structure, reduced the thickness of keyboard integral body.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Computor-keyboard thin film switch structure as shown in Fig. 1-1,1-2, include the plastic film layers 1 as bottom, be provided with circuit layer 2, insulating barrier 3, key cap layer 5 on plastic film layers 1 upper surface successively, be printed with several conductiving point a 6 to mutual separation, conductiving point b 7 at plastic film layers 1, the every couple of conductiving point a 6, conductiving point b 7 corresponding keycaps 5.Wherein the position of circuit layer 2 and insulating barrier 3 corresponding conductiving point a 6, conductiving point b 7 is equipped with cavity, is provided with elastic conducting layer 4 between electricity point a 6, the conductiving point b 7 of keycap 5 and correspondence.Elastic conducting layer 4 in the present embodiment is conductive rubber layer, and conductive rubber is placed on insulating barrier 3 upper surfaces, does not contact mutually with the upper surface of conductiving point b 7 with conductiving point a 6.Simultaneously between conductiving point a 6 and the conductiving point b 7, between conductiving point a 6 and the circuit layer 2, be respectively equipped with insulating barrier 3 between conductiving point b 7 and the circuit layer 2.
When using this keyboard, finger presses keycap 5, conductive rubber layer are under pressure downward distortion take place, and conductive rubber layer touches conductiving point a 6 and conductiving point b 7, and conductiving point a 6 and conductiving point b 7 constitute the loop by conductive rubber layer, realize the function of button.
Computor-keyboard thin film switch structure as shown in Fig. 2-1,2-2, include the plastic film layers 1 as bottom, be provided with circuit layer 2, insulating barrier 3, key cap layer 5 on plastic film layers 1 upper surface successively, be printed with several conductiving point a 6 to mutual separation, conductiving point b 7 at plastic film layers 1, the every couple of conductiving point a 6, conductiving point b 7 corresponding keycaps 5.Wherein the position of circuit layer 2 and insulating barrier 3 corresponding conductiving point a 6, conductiving point b 7 is equipped with cavity, is provided with elastic conducting layer 4 between electricity point a 6, the conductiving point b 7 of keycap 5 and correspondence.Elastic conducting layer 4 in the present embodiment is the pressure-sensitive conductive rubber layer, and this pressure-sensitive conductive rubber layer passes the insulating barrier cavity and places conductiving point a 6, conductiving point b 7 upper surfaces, directly contacts with conductiving point a 6, conductiving point b 7.
The pressure-sensitive conductive rubber layer is not when being under pressure, its characteristic presents high impedance, can not form the loop to conductiving point a 6 and conductiving point b 7, when the finger presses key emits 5 to be under pressure, pressure passes to downwards on the pressure-sensitive conductive rubber layer, the pressure-sensitive conductive rubber layer is under pressure, and its characteristic changes, and internal resistance sharply descends from high impedance, it is very little that internal resistance becomes, thereby make conductiving point a 6 and conductiving point b 7, become the loop by the pressure-sensitive conductive rubber layer, realize the function of button.
