And the most general now portable main flow electronic product is a digital camera, at the middle operational and controlled key button of digital camera because of factor attractive in appearance and handling etc., the edge that is provided in a side of digital camera mostly, therefore must see through soft printed circuit board (FPC) connector earlier when this key switch is set is connected on the circuit board, and sometimes because of the factor of circuit board line layout, make the dealer to lock with screw fashion, key switch can utilize soft arranging wire to connect when assembling in addition, and use artificial bonding wire connected mode directly the key switch contact to be connected on the electric wire, can finish the setting of key switch via complicated step.

Yet the technology of existing key switch setting is except having complicated step, FPC connector is also because of taking the usable floor area of circuit board, the circuit board service efficiency can't be increased, and sometimes must be with the screw FPC connector that locks, and then increase cost of processing, this key switch also must utilize soft arranging wire to connect in addition and the processing procedure of artificial welding, cause certain burden for manufacturing cost, and in the process of artificial welding, because of controlling artificial welding accuracy accurately, causing the damage of control button or the decline of product yield easily, therefore will how to solve the problem that above-mentioned prior art produces, is that present industry is badly in need of overcoming.

In view of this, The present invention be directed to above-mentioned problem, propose a kind of control switch syndeton, with the puzzlement of effective solution prior art.

Summary of the invention

Main purpose of the present invention, provide a kind of control switch syndeton, to control button and be arranged on the framework and utilize conducting strip to be electrically connected on the circuit board, exempt prior art flexible printed wiring board, soft arranging wire step is set, the manufacturing cost of electronic installation is reduced and processing procedure shortens.

Another object of the present invention provides a kind of control switch syndeton, because of not taking the usable floor area of circuit board, the circuit board size is dwindled, and then the volume that makes electronic installation microminiaturization more.

A further object of the present invention provides a kind of control switch syndeton, does not connect because of not needing artificial bonding wire connected mode in the assembling process, makes the damage that is difficult for causing the control button in the manufacture process, and then the yield of electronic installation is increased.

According to the present invention, a kind of control switch syndeton, it is arranged in the electronic installation, this syndeton comprises at least two conducting strips, these two conducting strips are arranged on the interior framework surface of this electronic installation, and conducting strip has one first conducting end and one second conducting end respectively, and a circuit board is arranged in addition, this circuit board is provided with at least two first electrical contacts, these two first conducting end are electrically connected to first electrical contact respectively, on framework surface and be positioned on two conducting strips at least one control switch is set, this control switch has at least two second electrical contacts, two second electrical contacts are electrically connected to two second conducting end respectively, this control button is electrically connected with circuit board.

Below by cooperate appended graphic explanation in detail by specific embodiment, when the effect that is easier to understand purpose of the present invention, technology contents, characteristics and is reached.

Embodiment

The present invention is a kind of control switch syndeton, it is the setting that is used for the key switch in the electronic installation, this electronic installation is portable mobile phone, digital camera or digital camera etc., and this is to be example explanation execution mode with the digital camera, and following be exactly the switch key and inner circuit board joint construction that illustrates on the digital camera.

See also Figure 1 and Figure 2; this control switch syndeton is arranged on the interior framework 10 of digital camera; this framework 10 is the members that can be assembled components or ejection formation; this framework 10 can supply battery; various spare part settings such as LCD screen; on the surface of framework 10, utilize the mode of adhesion that two conducting strips 12 are set; the material of this conducting strip 12 be the copper metal or or conducting metal constitute; these two conducting strips 12 have one first conducting end 14 and one second conducting end 16 respectively; wherein second conducting end 16 is shell fragment ends; and on conducting strip 12, be coated with a protective layer 18; only expose first conducting end 14 and second conducting end 16; be not subjected to extraneous aqueous vapor corrosion and damage in order to protection conducting strip 12, and this protective layer 18 can be selected from epoxy resin or general mackintosh.

This framework 10 has the storage tank end face of set battery or LCD screen in addition, this end face can be provided with a circuit board 20, this circuit board 20 is provided with two first electrical contacts 22, first conducting end 14 of two conducting strips 12 is electrically connected to first electrical contact 22 respectively, and this circuit board 20 is provided with plural electronic building brick 24, as image processor, image sensing component, sound effect processor etc.; And on framework 10 surface and be positioned at and on second conducting end 16 of two conducting strips 12 control switch 26 be set, this control switch 26 is switches of surface apparatus formula, this control switch 26 utilizes surface mounting technology (SMT) to be arranged on framework 10 surfaces, and this control switch 26 is elasticity push switch forms, utilize push switch to reach the purpose of switching, be provided with plural second electrical contact 28 in these control switch 26 bottoms, when control switch 26 is arranged on the framework 10, utilize the shell fragment end of second conducting end 16 to prop up second electrical contact 28 of control switch 26 bottom sides, control switch 26 and two conducting strips 12 are electrically connected, and then make control switch 26 be electrically connected to circuit board 20, so promptly finish the setting of this control switch syndeton.
