Abstract
The utility model discloses a metal touching key comprising a metal panel, an insulating layer, a conducting thin film, at least one piezoelectric ceramic chip and a PCB plate. Each function key position is labeled on the outer surface of the metal panel corresponding to the stress area of each function key, and is corresponding to one piezoelectric ceramic chip. The insulating layer and the conducting thin film are arranged between the metal penal and the piezoelectric ceramic chip. The insulating layer and the metal panel are adjacent, and the conducting thin film and the piezoelectric ceramic chip are adjacent. Leads corresponding to each piezoelectric ceramic chip are arranged on the conducting thin film. Each pair of leads has two conducting wires which are respectively connected with a negative electrode and a positive electrode of the corresponding piezoelectric ceramic chip. The PCB plate is arranged at the lowest layer, and is adjacent to the piezoelectric ceramic chip. A circuit on the PCB plate is connected with the leads of each piezoelectric ceramic chip for processing signals of the leads. Under the condition that the flexibility is not affected, the utility model improves the use life of the metal touching key, and reduces the product cost.
Description
Technical field
The utility model relates to a kind of metal touch key-press, relates in particular to a kind of metal touch key-press based on piezoelectric effect, belongs to the electric switch technical field.
Background technology
The application of touch-key at present is very extensive, because of its mechanical contact that does not need conventional keys, has avoided fragile, the stuck shortcoming of mechanical contact.Current comparatively popular capacitive induction soft-touch control can penetrate insulating material housing (glass, plastics or the like), the action of human body finger touch.Capacitive induction soft-touch control panel all adopts non-conducting material to make, and still, the general intensity of this material is not high, not wear-resisting, perishable, and sense of touch is also bad, and cost of manufacture is higher.Make the panel of button if use metal material, can avoid intensity not high, shortcoming such as not wear-resisting, but traditional metal touch-key in use human body need directly touch metal inductive disks, because of itself and 220V alternating current do not have safe buffer circuit, so the potential safety hazard of existing.If replace the non-conducting material panel application in the capacitive induction soft-touch control with metal key-press panel, can cause the button insufficient sensitivity, this technical scheme is also infeasible.Therefore developing a kind of new type of metal panel touch key-press has very important meaning.
The utility model content
The purpose of this utility model is to provide a kind of metal touch key-press based on piezoelectric effect, and it is not high enough, not wear-resisting, perishable to solve existing soft-touch control non-conducting material slab strength, the shortcoming that sense of touch is bad.
The purpose of this utility model is achieved by the following technical programs:
A kind of metal touch key-press comprises metal decking 1, insulating barrier 2,3, at least 1 piezoelectric ceramic piece 4 of conductive film, pcb board 5.The stress area of corresponding each function button, the position of each function button of sign on the outer surface of described metal decking 1, the corresponding piezoelectric ceramic piece 4 in each position, described insulating barrier 2 and conductive film 3 are between metal decking 1 and piezoelectric ceramic piece 4, insulating barrier 2 is adjacent with metal decking 1, conductive film 3 is adjacent with piezoelectric ceramic piece 4, the lead-in wire corresponding with each piezoelectric ceramic piece arranged on the conductive film 3, every pair of lead-in wire has two leads, link to each other with the both positive and negative polarity of corresponding piezoelectric ceramic piece respectively, described pcb board 5 is located at the bottom, and is adjacent with piezoelectric ceramic piece 4, circuit links to each other with the lead-in wire of each piezoelectric ceramic piece on the pcb board, and its switching signal is handled.
Compared with prior art, the beneficial effects of the utility model are: metal decking is used for touch key-press, is guaranteeing under sensitivity, the impregnable situation of accuracy, and the useful life of having improved touch key-press, and reduce product cost and production cycle.
