Abstract
A spring cap key device for conducting a zero-resistance multi-layer circuit is characterized in that a spring cap is used as an elastic support for keys and also used for sequentially increasing annular copper foil electrodes on the upper surface of a conducting circuit board one by one, and the key device for conducting the multi-layer circuit with small volume, simple and convenient production process, low cost and zero-resistance conducting performance is realized.
Description
Technical field
The present invention relates to electronic circuit key switching structure device, more specifically to the spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance.
Background technology
In the prior art, no matter be silica gel conductive rubber or metal leaf springs structural type key device, it all is single level conducting form, circuit turn-on when being button operation was finished in the time, if when needing multi-level circuit turn-on (as electronic organ, the dynamics of the keyboard of fender performance key circuit structure just needs multi-level circuit turn-on---and every keyboard unit has two silica gel conduction buttons of just differing of contact respectively, two time turning circuits can be divided in the contact of these two buttons during operation, time difference is calculated the dynamics of decision operation thus) then need a plurality of silica gel push-button switches to finish, this multi-level circuit turn-on version by a plurality of silica gel conduction buttons has the high area of volume big, production cost is higher, manufacturing process is difficult, silica gel conduction button electric conductivity not good enough (resistance is arranged), and service time in addition is long also can to fall carbon powder so that be subjected to bigger restriction useful life.
Summary of the invention
The object of the present invention is to provide the spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance, it is big that this device can overcome the high area of volume of finishing multi-level circuit turn-on by a plurality of silica gel push-button devices of the prior art, production technology is complicated, electric conductivity is not good enough, and useful life, more limited grade was not enough.
The spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance provided by the invention is characterized in that, by the conducting effect of metal spring as the support elastic force and the circuit board upper surface copper foil electrode of button.
The spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance provided by the invention, its feature also is, the moulding of described spring compressor is similar in appearance to inverted funnel, and can progressively be carried out the transition to by bottom striking circuit board upper surface copper foil electrode in the stroke of pressing that moves downward has middle part and top striking circuit board upper surface copper foil electrode simultaneously.
The spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance of the present invention, its feature also is, described circuit board upper surface copper foil electrode is made up of the gold-plated Copper Foil of a plurality of outer imperial palace circlet shape circles, is beneficial to spring compressor ecto-entad in the downward stroke of pressing and increases the contact conducting one by one.
Implement the spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance of the present invention, can realize that a kind of volume area is less, production technology is easy, and cost of manufacture is low, the key device of the multi-level zero resistance circuit turn-on that serviceability is reliable and stable,
Summary of drawings
Below, in conjunction with the accompanying drawings and embodiments, the present invention is described in further detail:
Fig. 1 is the physical embodiment schematic diagram of explanation spring compressor button of the present invention.
As shown in the figure, [1] is the sterogram of spring compressor of the present invention; The bottom that comprises [1.1] spring compressor, [1.2] top of the middle part of spring compressor and [1.3] spring compressor, [2] be of the present invention and the gold plated copper foil electrode contacted circuit board upper surface of spring compressor, comprise [2.1] outer ring electrode, [2.2] centre circle electrode and [2.3] inner ring electrode, button only has the spring compressor bottom to touch the outer ring electrode of circuit board upper surface when inactive inactive state, during operation at first button pressed to spring compressor middle part and bottom simultaneously the contact circuit plate upper surface while contact the outer ring electrode and the centre circle electrode of turning circuit plate upper surface with the middle part by the bottom of spring compressor, next button presses to spring compressor top again, middle part and bottom striking simultaneously circuit board upper surface is the bottom of while by spring compressor, the middle part contacts the outer ring electrode of turning circuit plate upper surface with top, thereby centre circle electrode and inner ring electrode are finished the function of the spring compressor key device of the multi-level circuit turn-on of a kind of zero resistance of the present invention.
