Description

Button

[technical field]

The utility model relates to a kind of button, especially refers to a kind of button that is applied on the portable electron device.

[background technology]

The prior art relevant with the utility model can be consulted the U.S. the 4th of bulletin on January 13rd, 1987,636, No. 593, the United States Patent (USP) the 5th that on January 13rd, 1998 was announced, 708, No. 428, the United States Patent (USP) the 5th that on May 5th, 1998 was announced, 747, No. 756, in the keyboard that these prior aries disclosed, light-emitting diode is all concentrated and is located on the circuit board, this circuit board one end and main circuit board electrically connect and power supply are provided for all light-emitting diodes, the defective of this kind deploying mode is: when the electronic installation that is equiped with this keyboard in use, all light-emitting diodes can be bright simultaneously or dark simultaneously, can not produce light-emitting diode produces the light and shade flicker with the operation of button effect.

[utility model content]

The purpose of this utility model is to provide a kind of actuating with single button to produce the button of light-emitting diode light and shade flashing function.

The utility model is that group is located on the portable electron device circuit board, comprises light conductor, switching device and illuminating module, and wherein illuminating module matches with switching device and can produce the effect of light and shade flicker when key actuation.

Compared with prior art, the utility model is provided with the switching device that matches with illuminating module, when key actuation simultaneously by an illuminating module is set in button in single button, switching device produces switch motion, further makes illuminating module produce the effect of light and shade flicker.

[embodiment]

Please refer to Fig. 1 to shown in Figure 4, the utility model button 1 comprises housing 10, is mounted on light conductor 2, illuminating module, switching device 6 and circuit board 7 in the housing 10.

Housing 10 comprises that an arcuation surface 11, runs through the receiving space 12 of housing 10 and be located at the sidewall 14 of receiving space 12 outsides.In addition, described sidewall 14 bottoms are provided with a fluting 13.

Light conductor 2 comprises main part 20 and is located at the pressure section 25 of main part 20 lower ends that wherein main part 20 is provided with a press surface 26 and outer wall 21.Offer an opening 22 on the described outer wall 21, be provided with the holding hole 24 that an accepting groove 23 and is used for fixing flexible PCB 5 in the described opening 22.

Illuminating module comprises flexible PCB 5, be mounted on the light-emitting diode 3 on the flexible PCB 5 and flexible PCB 5 is retained on retaining piece 4 on the light conductor 2.

Retaining piece 4 is provided with auxiliary section 40 and the extended alignment pin 41 of 40 1 sides from the auxiliary section.

Flexible PCB 5 roughly is " U " font of falling down, in the middle of its top a bending part 51 is arranged, and offer location hole 52 on the bending part 51, and flexible PCB 5 upper end is a holding section 50, and light-emitting diode 3 is located on this holding section 50; Light-emitting diode 3 together is contained in the accepting groove 23 of light conductor 2 with described holding section 50.In addition, the flexible cable bottom is a weld part 53.

Switching device 6 is provided with a framework 60 and protrudes the Actuator Division 61 of framework 60, discloses because of having in the prior art as for other structure of switching device 6, repeats no more herein.

Circuit board 7 is provided with some conductive paths 70.

During assembling, switching device 6 is located on the conductive path 70 of circuit board 7.The weld part 53 of flexible PCB 5 also welds connection mutually with conductive path 70.The pressure section 25 of light conductor 2 connects with the Actuator Division 60 of switching device 6.Holding section 50 on the flexible PCB 5 together is contained in the accepting groove 23 of light conductor 2 with the light-emitting diode of establishing thereon 3, simultaneously 4 groups of retaining pieces are located on the light conductor 2, wherein auxiliary section 40 parts of retaining piece 4 are housed in the opening 22 of light conductor 2, and alignment pin 41 by with light conductor 2 on holding hole 24 and the location hole 51 on the flexible PCB 5 cooperate, flexible PCB 5 is fixed on the light conductor 2.At last, 10 groups of housings are located on the light conductor 2, wherein the main part 20 of light conductor 2 is contained in the receiving space of housing 10, and its press surface 26 is dashed forward in the curved surfaces 11 of housing 10, and the fluting 13 of housing 10 sidewalls 14 also is fastened on the outside of the auxiliary section 40 of retaining piece 4.

During use, push the press surface 26 of light conductor 2, make the pressure section 25 of light conductor 2 press down the Actuator Division 60 of switching device 6, make the light-emitting diode 3 that is located on the flexible PCB 5 connect luminous, through light conductor 2 conduction, make that further the surface of button 1 is bright luminous.

During pressurized, because the elastic force of switching device 6 Actuator Divisions 60 makes switching device 6 disconnect, light-emitting diode 3 does not open circuit not luminous button 1, thereby button 1 surface is not luminous yet.

Therefore, button 1 just can produce the effect of light and shade flicker in its surface in use.

Really, illuminating module of the present utility model also can only comprise a light-emitting diode, and this moment, the contact feet of light-emitting diode can directly weld on the ground circuit board 7.And housing 10 also can be made an integral body with light conductor 2.
