Abstract
The utility model relates to field of electronic product technology, especially to a press key used in electronic product. The elastic element is bonded directly on a conductive thin film corresponding to a contact on the conductive thin film, and a conductive convex part which can contact and connect the normal-open contact of the circuit is arranged on a corresponding contact in the elastic element. The utility model has the advantages of light structure, material saving, low price, simplified production process and effectively improved productivity. The elastic element is directly bonded to the conductive thin film, thus dislocation is not easy to happen and the conductive circuit is better and more stable.
Description
Technical field:
The utility model relates to technical field of electronic products, refers in particular to a kind of button that is used on the electronic product.
Background technology:
The button of common electronic product, its conductive film are generally established correspondence and are 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 if having, and with causing the contact on each film not align, causes circuit turn-on bad.The button that occurs single laminar conductive film subsequently, but its flexible member is to be bonded on the transparent insulation sheet that is arranged on the conductive film.During use, establish in the flexible member conductive stud grain need pass on the transparent insulation sheet corresponding perforate just the contact on conductive film touch, thus, also can occur causing poor flow owing to the dislocation of transparent insulation sheet, set up a slice transparent insulation sheet simultaneously, not only the assembling location is comparatively loaded down with trivial details, and production efficiency is low, but also be to consume material, cost is higher.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, provides a kind of circuit turn-on more to stablize good button, reduces consumable quantity, reduces cost.
The utility model is achieved by the following technical solution: the contact on the corresponding conductive film of flexible member directly is bonded on the conductive film, and corresponding contact is provided with the conduction protuberance that can touch the circuit passband normal opened contact in the flexible member; The relative bonding interface with conductive film of flexible member is reserved with through hole; The part circuit that is in juxtaposition in the circuit of arranging on the described conductive film has insulating barrier to separate.
The utility model structure is light and handy, economizes material, cheap, and production process is greatly simplified, and effectively boosts productivity.
Description of drawings:
Accompanying drawing 1 is a schematic perspective view of the present utility model;
Accompanying drawing 2 is a perspective exploded view of the present utility model;
Accompanying drawing 3 is the circuit arrangement schematic diagram of conductive film.
Embodiment:
See accompanying drawing 1～3, the utility model includes conductive film 1, flexible member 2, and conductive film 1 is single laminar, and corresponding each button is provided with the circuit junction of often opening 11 on it; Contact 11 on the flexible member 2 corresponding conductive films 1 directly is bonded on the conductive film 1, and corresponding contact 11 is provided with the conduction protuberance 21 that can touch logical this circuit normal opened contact 11 in the flexible member 2.Flexible member 2 is bowl-shape, flexible member 2 be reserved with through hole 22 with conductive film 1 relative bonding interface, and the part circuit that is in juxtaposition in the circuit of arranging on the conductive film 1 has insulating barrier 12 to separate.
During use, conductive film 1 is arranged on the respective base, and the end 23 of pushing of flexible member 2 is connected with keycap.When pressing keycap, the corresponding contact 11 that the conduction protuberances 21 in the flexible member 2 promptly can be conflicted on the conductive film 1 forms turning circuits, will push signal and be sent in the electronic product main frame.Flexible member 2 directly is bonded on the conductive film 1, thereby is difficult for misplacing, and turning circuit is more stable good, and simple and convenient assembly, economizes material.Flexible member 2 be reserved with ventilative through hole 22 with conductive film 1 relative bonding interface, when flexible member 2 pressed down, its inner air was flowed out by through hole 22; When the cancellation downforce was loosened flexible member 2, air flowed in the flexible member 2 from through hole 22, and reinstatement is waited for and being pushed once more, makes pressing operation brisk smooth and easy.
