Abstract
A keyboard electric circuit monolayer thin membrane base sheet and a waterproof silica gel button switch. A keyboard electric circuit is printed on one surface of a thin membrane base sheet punched into a certain specification, a pair of adjacent contact points which surface is made with a conducting layer are arranged on two circuits requiring to be conducted, waterproof silica gel buttons are respectively stuck on the contact points, a pair of actuation columns opposite to the circuit contact points at the lower part are arranged at the center of the top sheet of the inner cavity of the waterproof silica gel button, conducting layers are made on the contacting surface of the actuation columns, and air discharging groove holes are arranged on the top sheet of the button. Compared with the common keyboard electric circuit thin membrane base sheet, two layers of thin membranes are canceled in the utility model, and simultaneously because the air discharging holes of the waterproof silica gel button are arranged on the top sheet, to effectively prevent water to intrude into the circuit base sheet. The product is simpler and lighter, the cost is saved, the operation is steadier and more reliable, and the utility model can be extensively applied on the keyboards of various computers, mobile phones and instrument devices.
Description
Technical field
The utility model relates to a kind of circuit film substrate and the key switch in the keyboard member, particularly keyboard on the equipment such as computer, mobile phone.
Background technology
Existing keyboard circuit film substrate and key switch are made up of three-layer thin-film and silica gel push-button usually, be printed with circuit and relative conducting contact on its upper and lower layer film opposite face respectively, be provided with the intermediate insulation interlayer between the upper and lower layer film, on topmost thin film, be bonded with silica gel push-button corresponding to the conducting contact.The structure of foregoing circuit film substrate and key switch is complicated, and manufacturing procedure is many, and raw material consume big, and production cost is higher.
Summary of the invention
The purpose of this utility model, provide a kind of simple in structure, action more flexibly, reliable, and more frivolous material-saving and favourable keyboard circuit single thin film substrate and the water-proof silica-gel key switch that reduces manufacturing cost.
Technical solution of the present utility model is: it comprises film substrate and the silica gel push-button that is printed with keyboard circuit, it is characterized in that on the one side of the die-cut film substrate that forms certain specification, being printed with keyboard circuit at one, and on two circuit that needs connect, be provided with a pair of adjacent, the surface adds the contact that is shaped on conductive layer, around each to the contact respectively cementation the water-proof silica-gel button is arranged, this water-proof silica-gel button inner chamber top flat inner face center is provided with the start post corresponding to a pair of circuit contact of its below, be shaped on conductive layer on the start post contact-making surface, also offer exhaust slot on the water-proof silica-gel button top flat.
The beneficial effects of the utility model are: its more common keyboard circuit film substrate has been save two-layer film, has reduced the raw material consumption significantly, has simplified production process, has reduced production cost, has improved production efficiency; Because the steam vent of its silica gel push-button is located on the top flat, can prevent the water intrusion circuit substrate effectively simultaneously.Therefore this product is not only simple more, light and handy, and uses also more reliable and more stable.It can be widely used on the keyboard of various computer, mobile phone, instrumentation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is a keyboard circuit film substrate structural representation of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Keyboard circuit film substrate 1 adopts PC or PET single layer plastics films, and through the die-cut substrate that forms the some mechanisms of being furnished with of certain specification hole 10, be printed with circuit 2 and some adjacent paired circuit connect contact 9 on the one side of this substrate, the connecting to add on the face of contact 9 is printed on the good conductive carbon ink of electric conductivity 8; Button 3 selects for use mechanical performance, electrical insulation capability good, the intensity height, the compression molding of aging-resistant silica gel material, its inner chamber top flat 4 inner face centers be provided with substrate on adjacent a pair of circuit connect the start post 6 that matches contact 9, be coated with on the contact-making surface of start post 6 and be shaped on carbon ink conductive layer 8, be symmetrical in start post 6 on the top flat 4 and offer exhaust slot 5, also be evenly equipped with post angle 7 on top flat 4 inner faces.With above-mentioned water-proof silica-gel button 3 respectively cover cap connect on the contact 9 at every pair of circuit of substrate, and its base and substrate are adhesively fixed.
Claims (2)
