【Brief description of the drawings】
Fig. 1 is board structure of circuit side profile schematic diagram of the present utility model.
Fig. 2 is the utility model board structure of circuit explosion figure.
Wherein：Between 1- circuit boards, 2- waterproofs adhesive film, 3- diaphragms, the exposed printed substrates of 4-, 5- are sealed, 6- leaves a blank
Position, 7-LED lamps, 8- electronic components, 9- insulators, 21- through holes, 31- conductors, 51- spacing distances space.
【Specific embodiment】
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to Fig. 1, Fig. 2, a kind of board structure of circuit of full key board Lothrus apterus backlight waterproff keyboard, including 1- circuit boards, 2-
Between waterproof adhesive film, 3- diaphragms, the exposed printed substrates of 4-, 5- are sealed, 6- leaves a blank position, 7-LED lamps, 8- electronic components, 9-
Insulator, 21- through holes, 31- conductors, 51- spacing distances space.
The waterproof adhesive film 2 is bonded on the circuit card 1, and centre is provided with through hole 21.
The diaphragm 3 is bonded on waterproof adhesive film 2.
The circuit board 1, waterproof adhesive film 2, the three of diaphragm 3 are bonded together, and make to be located at middle waterproof adhesive film 2
On through hole 21 formed one sealing space 5.
The exposed printed substrate 4 is set on the circuit card 1,5 middle part positioned between sealing.
The conductor 31 is arranged under diaphragm 3,5 positioned between sealing in, face exposed printed substrate 4, it is described to lead
There is certain spacing distance space 51 between body 31 and exposed wiring board 4.
The back of the circuit board 1 is provided with a position 6 of leaving a blank, 5 positioned between sealing under, printed wire and waterproof adhesive film it
Between position；The LED 7 is arranged on and leaves a blank in position 6.
The back of the circuit board 1 is provided with electronic component 8, the need for the electronic component acts on keypress function use.
Wrapped up by one layer of insulator 10 outside the electronic component 8, LED 7, be sealed in the back of circuit board 1.
