Abstract
Disclosed is a touch key, which comprises an electrically insulated panel, a circuit board and a compressed conductor positioned between the panel and the circuit board, and the conductor comprises an induction part, an elastic deformation part and a connecting part, wherein, the elastic deformation part and the connecting part are coiled by conductive spring wires, the connecting part is fixedly connected with a base made of conductive material, and the base has at least one pin which penetrates through a corresponding hole in the circuit board and is welded on the circuit board. Because the pins are inserted into plug-in pin holes of the circuit board when in welding, the conductor will not sway over when encountering large shaking and is more stable, need no special jig, and can save the production cost; in addition, because the pins are in stable matching with the pin holes of the circuit board, empty soldering will not be caused generally, and the stability and conductivity of the key are improved.
Description
[technical field]
The utility model relates to a kind of touch-key, and it can be used for various electronics or electric product.
[background technology]
Touch-key is very common at electronics and electric field, and is especially commonplace in household appliance technical field.The electric conductor that it is elastic component that touch-key comprises a main body usually between circuit board and guidance panel, and is in confined state, thereby tight attended operation panel and circuit board transmit changes in capacitance on the guidance panel.
The electric conductor of traditional touch-key is generally cylindrical or pyramidal structure by the wire coil coiled near an end of circuit board, the supporting surface diameter is less, and center of gravity is higher, tremble easily in the axial direction in addition, comprehensive above a variety of causes, these electric conductors are very unstable when vertical the placement.In the process of electric conductor and circuit board welding, it need be positioned on the circuit board that is added with tin cream, send into the melt in furnace tin cream then and realize welding.In order to prevent that electric conductor from skewing or shake displacement in this process, often need to customize special anchor clamps and fix, production cost is very high, complex process.In addition, because the part of electric conductor and circuit board welding is the pitch of the laps of contact portion,, promptly may cause empty weldering in case small displacement takes place electric conductor in welding process.
[summary of the invention]
At above problem, the purpose of this utility model provides a kind of improved touch-key, and its electric conductor anchor clamps specially can be realized installing, and can improve the welding reliability between electric conductor and the circuit board.
To achieve these goals, the touch-key that the utility model disclosed comprises the panel of an electric insulation, one circuit board, electric conductor between described panel and described circuit board by compression, this electric conductor comprises an induction part, a strain portion and a connecting portion, wherein strain portion and connecting portion are by the spring wire coiled of conduction, described connecting portion is fixedlyed connected with a base of being made by electric conducting material, described base has at least one pin, described pin passes hole corresponding on the described circuit board, and is welded on the circuit board.
Because pin inserts in the plug-in unit pin bores of circuit board during welding, electric conductor can not skew under bigger rocking yet, and is more stable, needn't use special anchor clamps, saved production cost; In addition, cooperate, generally can not cause empty weldering, improved the stability and the conductivity of button because pin is stablized with the pin bores on the circuit board.
[description of drawings]
Below in conjunction with drawings and embodiments the present invention is described in further detail.
Fig. 1 is the wherein member schematic diagram of the touch-key of a kind of embodiment of the utility model;
Fig. 2 is the structural representation according to electric conductor in the touch-key of the present utility model.
[embodiment]
As shown in Figures 1 and 2, touch-key 10 comprises control panel 1, one circuit board 2 of an electric insulation, and the electric conductor 3 between panel 1 and circuit board 2.Electric conductor 3 has an induction part 4, strain portion 5, a connecting portion 6 that radially extends.Finish assembling back electric conductor 3 and be compressive state ground between circuit board 2 and control panel 1, so induction part 4 is fitted with control panel 1 all the time, when inductor contact or on during induction part 4 pairing positions near control panel 1, electric capacity changes, so electric conductor 3 transmits this variation, the circuit on the circuit board 2 carries out corresponding operating.
In the embodiment shown in Figure 2, connecting portion 6 is fixedlyed connected with a metab 8.Metab 8 is preferably sheet type, can also comprise four extensions 9 all around, and extension 9 can upwards be turned up and be buckled on the connecting portion 6, so realize fixedlying connected of connecting portion 6 and metab 8.The number of extension 9 is not limited to four, but in order to reach location preferably, needs three at least.In addition, connecting portion 6 can be realized by welding or other mechanical connection manners with being connected also of metab 8.Except metal, base 8 can also be with other any suitable electric conducting materials that it may occur to persons skilled in the art that.In addition, the structure that connecting portion 6 is not limited to radially extend can also be the part of strain portion 5.
Two pins 11 are stretched out in metab 8 bottoms.When electric conductor 3 was installed, the pin 11 on the metab 8 passed the plug-in unit pin bores (not showing on the figure) on the circuit board 2, and is welded on the circuit board 2.Passed plug-in unit pin bores on the circuit board 2 owing to advance pin 11 before the brazier welding, electric conductor 3 needn't use anchor clamps also can not skew.In addition,, generally can not cause empty weldering, improve the stability and the conductivity of device because pin 11 has highly stable matching relationship with pin bores.
Above describe and various embodiment shown in the drawings only is used to illustrate the utility model, be not of the present utility model all.In the category of basic fundamental thought of the present utility model, the those of ordinary skill of correlative technology field at any type of change that the present invention carried out all within protection range of the present utility model.
