Description
[technical field]
The utility model relates to a kind of capacitor induction type touch button device.
[background technology]
At present; Be applied in the capacitor induction type touch button device on the electronic lock, generally comprise main PCB plate and secondary pcb board, the main PCB plate is arranged on the inside of electronic lock housing; The main PCB plate is provided with control circuit; Secondary pcb board is installed in the surface of electronic lock housing, on secondary pcb board, is provided with induction electrode, connects through electric wire between main PCB plate and the secondary pcb board.The capacitor induction type touch button device of said structure has following shortcoming:
1, product structure is complicated, and processing is inconvenient, and processing cost is high.
2, this product is installed on the electronic lock or from electronics contract disassemble convenient inadequately.
3, when product test, must be with coupling together and could accomplish through electric wire between main PCB plate and the secondary pcb board, test is convenient inadequately.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, provides one simple in structure, easy to process, and cost of manufacture is low, and installation or removal are convenient, the capacitor induction type touch button device of convenient test.
For realizing above-mentioned purpose, the utility model has adopted following technical proposal:
A kind of capacitor induction type touch button device; Include basic unit's pcb board; Be furnished with a plurality of induced electricity pole pieces as inductive switch in the front of basic unit's pcb board; In the middle of the induced electricity pole piece, be provided with light-emitting diode, be provided with the signal of handling the reception of induced electricity pole piece and the control circuit of controlling lumination of light emitting diode at the back side of basic unit's pcb board; Be glued with the top layer pcb board in the front of basic unit's pcb board, on the pcb board of top layer, have and a plurality of one to one loopholes of a plurality of induced electricity pole pieces, said light-emitting diode extend in the loophole.
Said top layer pcb board is close on basic unit's pcb board through double faced adhesive tape.
On the edge of basic unit's pcb board, have a plurality of welding breach, on the pcb board back side, top layer, be provided with pad with the corresponding position of welding breach.
On the top layer pcb board back side be positioned at loophole around also be provided with the spacer corresponding with the induced electricity pole piece.
The beneficial effect of the utility model is:
1, this product only is made up of two fixing pcb boards together, and is simple in structure, easy to process.
2, induction electrode of this product and control circuit all are integrated on basic unit's pcb board; The top layer pcb board just plays the effect of assist location and light rear-projection; Do not have electric wire to connect between two pcb boards, like this, with this product be installed on the electronic lock or from electronics contract disassemble very convenient.
3, when product test, need not basic unit's pcb board and top layer pcb board be fitted together, only just can accomplish test, convenient test with basic unit's pcb board.

[embodiment]
A kind of capacitor induction type touch button device; Include basic unit's pcb board 1; Be furnished with a plurality of induced electricity pole pieces 11 as inductive switch in the front of basic unit's pcb board 1; In the middle of induced electricity pole piece 11, be provided with light-emitting diode 12, be provided with at the back side of basic unit's pcb board 1 and handle the luminous control circuit of signal that induced electricity pole piece 11 receives and control light-emitting diode 12; Be glued with top layer pcb board 2 in the front of basic unit's pcb board 1, on top layer pcb board 2, have and a plurality of one to one loopholes 21 of a plurality of induced electricity pole pieces 11, said light-emitting diode 12 extend in the loophole 21.During use; This product is fixed on electronic lock inside; Then electronic lock printing opacity cover and top layer pcb board 2 are close to, the light that light-emitting diode 12 sends is radiated at the electronic lock transparent surface after through loophole 21 and covers the formation luminous point, and the hole wall of loophole 21 has the optically focused effect.The user represents the luminous point of different digital or symbol with finger touch; Corresponding induced electricity pole piece 11 can be sensed and send signal to control circuit; Control circuit is passed to the main control chip on the electronic lock after handling, and the action of main control chip control password pellet shot from a slingshot realizes unblanking or locks action.
Said top layer pcb board 2 is close on basic unit's pcb board 1 through double faced adhesive tape.On the edge of basic unit's pcb board 1, have a plurality of welding breach 13, on top layer pcb board 2 back sides, be provided with pad 22 with welding breach 13 corresponding positions.After top layer pcb board 2 and basic unit's pcb board 1 bond together, the edge of top layer pcb board 2 and basic unit's pcb board being welded with pad 22 places at welding breach 13, to strengthen two compactnesses between the pcb board through electric welding.
On the top layer pcb board 2 back sides be positioned at loophole 21 around also be provided with the spacer corresponding with induced electricity pole piece 11.Because the distance between top layer pcb board 2 and the induced electricity pole piece 11 has been raised in the existence of spacer like this, strengthen the radiation response of light-emitting diode 12.
