Abstract
The utility model discloses a spring supporting structure for inductive touch keys, wherein the structure comprises a supporting spring, wherein one end of the supporting spring is connected with an electrode of a circuit board. The spring supporting structure is characterized in that the spring and the circuit board are connected together through an inserted-connecting mode, the connecting end of the spring and the key is a cap-type structure whose diameter is increased gradually. The cap-type structure of the connecting end of the spring and the key forms a plane structure or a conical face structure, and the spring on the lower portion of the cap-type structure is a cylindrical spring. The spring supporting structure for the inductive touch keys of the utility model has the advantages of low cost, convenient manufacture and production and solid structure.
Description
Technical field
The utility model patent relates to electrical equipment touch key-press accessory, particularly relates to a kind of induction touch press-key spring.
Background technology
The induction touch press-key of prior art adopts spring to realize supporting more, one end of spring and the welding of the electrode tip of circuit board, be set with a planar metal plate on the other end, to increase the button area, the connected mode of itself and metallic plate generally is that a folder mouthful is set on metallic plate, and the end of spring sandwiches a mouthful internal fixation connection.The shortcoming of aforesaid way is: 1, cost height needs the preparation metal sheet; 2, processed complex, need be welded to connect and with the fixedlying connected of metallic plate; 3, structure is insecure, is prone to the fault that metallic plate and spring break away from.
The utility model content
The utility model patent provide a kind of cost low, make easy to process, well-set induction touch press-key spring cupport structure.
The utility model is realized above-mentioned purpose by following technical solution:
This induction touch press-key is with comprising a support spring in the spring cupport structure, one end of support spring is connected with the wiring board electrode, it is characterized in that, be to link together by the mode of pegging graft between this spring and the wiring board electrode, the link of spring and button is the cap-like structure that diameter increases successively.
The cap-like structure of the link of described spring and button constitutes planar structure;
The cap-like structure of the link of described spring and button constitutes cone structure;
Described cap-like structure lower springs is the column spring.
Adopt the following advantage that the utlity model has of said structure:
1, saved the metallic plate of prior art, the cap-like structure that adopts diameter to increase successively substitutes, and cost is low;
2, processing is simple and convenient, and the utility model need not to adopt and manually metallic plate is connected with spring, also need not welding;
3, structure is more firm, and the utility model has adopted the inserting mode with wiring board, and adopts and to have omitted being connected of spring and metallic plate, and structure is more simple firm.

Description of reference numerals: 1, support spring 2, button 3, wiring board 1-1, cap-like structure end 1-2, column structure end
Embodiment
As shown in Figure 1, induction touch press-key spring cupport structure of the present utility model, comprise a support spring 1, one end of support spring 1 is connected with wiring board 3 electrodes, be to link together between this spring 1 and wiring board 3 electrodes by the mode of pegging graft, spring 1 is the cap-like structure 1-1 that diameter increases successively with the link of button 2, described spring and button link cap-like structure 1-1 constitute cone structure, adopt conical surface cap-like structure spring both as the resilient support effect of button, play the effect that increases conducting button conducting area successively one by one again, thereby implementation structure is firm, production technology is easy, lower-cost advantage, its cap-like structure lower springs are column spring 1-2.
As other embodiment of the present utility model, the cap-like structure of described spring and button link can also constitute planar structure.
Claims (4)
1, a kind of induction touch press-key spring cupport structure, comprise a support spring, one end of support spring is connected with the wiring board electrode, it is characterized in that, be to link together by the mode of pegging graft between this spring and the wiring board electrode, the link of spring and button is the cap-like structure that diameter increases successively.
2, induction touch press-key spring cupport structure according to claim 1 is characterized in that, the cap-like structure of the link of described spring and button constitutes planar structure.
3, induction touch press-key spring cupport structure according to claim 1 is characterized in that, the cap-like structure of the link of described spring and button constitutes cone structure.
