Abstract
The utility model discloses a novel welding-free touch induction key. The novel welding-free touch induction key comprises an electrical insulation panel, a circuit board and a compressed elastic conductor located between the panel and the circuit board. The elastic conductor is composed of a fixing part, an elastic part and a connecting part, wherein the fixing part, the elastic part and the connecting part are arranged from top to bottom, the connecting part has a shape of an inverted cone, a through hole is disposed on the panel corresponding to the connecting part, the connecting part is inserted in the through hole, and a base of the fixing part is fixedly connected with the circuit board through silica gel. A perforation is disposed at an upper part of the elastic conductor. The connecting part and the panel are assembled through a clamping, assembling or pasting mode. Through adoption of the elastic conductor between the panel and the circuit board, compression between the panel and the circuit board can be controlled, and the service life is prolonged; cost is reduced through a welding-free mode; and elasticity of products are increased since the through hole is additionally arranged under the elastic conductor.
Description
Technical field
The utility model relates to a kind of novel touch sensible button of exempting to weld.
Background technology
Touch-key is very common at electronics and electric field, and is especially commonplace in the home electric 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 by the wire coil coiled near an end of circuit board, in the process of electric conductor and circuit board welding, it need be positioned on the circuit board of oiling tin cream, send into the melt in furnace tin cream then and realize welding, this process often needs to customize special anchor clamps and fixes and cause production cost to raise, simultaneously, namely may cause empty weldering in case at the welding process electric conductor small displacement takes place.
The utility model content
The utility model provides a kind of novel touch sensible button of exempting to weld, and the structure that is used for solution prior art touch sensible button causes the cost rising or causes empty problem of welding because of production technology.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of novelly exempts to weld the touch sensible button, adopts following technical scheme:
A kind of novel touch sensible button of exempting to weld, wherein, the panel, a circuit board and an elastic electric conductor between described panel and described circuit board by compression that comprise an electric insulation, described elastic electric conductor is made up of from top to bottom fixed part, elastic portion and connecting portion, described connecting portion is inverted cone, the corresponding through hole that is provided with described connecting portion on the described panel, described connecting portion embeds in the described through hole, and described fixed part base is connected by silica stationary with described circuit board.
Particularly, described elastic electric conductor top is provided with a perforation.
Particularly, described connecting portion and described panel assemble by the mode of card, dress or subsides.
Particularly, described elastic electric conductor sheet resistance is not higher than 10 kilohms.
Particularly, described connecting portion and circuit board contact portion are covered copper for insulation push button signalling line.
The utility model provides a kind of novelly exempts to weld the touch sensible button, elastomer is set between panel and the circuit board can makes that the compression between panel and the circuit board is controlled by being arranged on, increased useful life, the mode of removing welding simultaneously from has also reduced cost, in the elastomer bottom elasticity that through hole has also increased product is set.
Description of drawings
Fig. 1 is the described novel structural representation of exempting to weld the touch sensible button of the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of novelly exempts to weld the touch sensible button, elastomer is set between panel and the circuit board can makes that the compression between panel and the circuit board is controlled by being arranged on, increased useful life, the mode of removing welding simultaneously from has also reduced cost, in the elastomer bottom elasticity that through hole has also increased product is set.
Novelly exempt to weld the touch sensible button and be described in detail what the utility model embodiment offered below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model embodiment provides a kind of novelly exempts to weld the touch sensible button, wherein, the panel 1, a circuit board 2 and an elastic electric conductor 3 between described panel and described circuit board by compression that comprise an electric insulation, described elastic electric conductor 3 is made up of with connecting portion 6 from top to bottom fixed part 4, elastic portion 5, described connecting portion 6 is inverted cone, on the described circuit board 2 with the described connecting portion 6 corresponding through holes 7 that are provided with, described connecting portion 6 embeds in the described through hole 7, and described fixed part 4 bases and described panel 1 are connected by silica stationary.
Particularly, described elastic electric conductor 3 tops are provided with a perforation 8.
Particularly, described connecting portion 6 assembles by the mode of card, dress or subsides with described circuit board 2.
Particularly, described elastic electric conductor 3 sheet resistances are not higher than 10 kilohms.
Particularly, described connecting portion 6 covers copper with circuit board 2 contact portions for insulation push button signalling line.
This button is suitable for use on the full paster touch control board most, avoids plug-in unit and wave soldering, directly assembles after the tin cream Reflow Soldering to get final product.
The utility model provides a kind of novelly exempts to weld the touch sensible button, elastomer is set between panel and the circuit board can makes that the compression between panel and the circuit board is controlled by being arranged on, increased useful life, the mode of removing welding simultaneously from has also reduced cost, in the elastomer bottom elasticity that through hole has also increased product is set.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion by described protection range with claim.
