Abstract

A key is assembled on circuit board of portable electronic device, which comprises a shell, a switching device, an elastic actuating part and a lighting module. The lighting module and the switching device are welded on circuit board. The elastic actuating part can actuate the switching device when pressed by the shell. Then the lighting module is switched on to generate the flashing effect of bright or dark when operating single key.

Description

Button

[technical field]

The utility model relates to a kind of button, relates in particular to a kind of button that is applied on the electronic installation.

[background technology]

The prior art relevant with the utility model can be consulted the United States Patent (USP) 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 and on May 5th, 1998 bulletin United States Patent (USP) the 5th, 747, No. 756, in the button that these prior aries disclosed, light-emitting diode is all concentrated and is located on the circuit board, this circuit board 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 button in use, all light-emitting diode can be bright simultaneously or dark simultaneously, can not produce single light-emitting diode pushing and produce the effect of light and shade flicker with single button.

[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 and shade flicker effect.

For achieving the above object, the utility model adopts following technical scheme: the utility model group is located on the portable electron device circuit board, comprise housing, switching device, resilient actuating spare and light emitting module, described light emitting module one end and switching device all are welded on the circuit board, and resilient actuating spare is located at the housing below.

Compared with prior art, the single button that the utility model disclosed is provided with independently light emitting module, and button also is provided with the switching device that matches with light emitting module simultaneously, when certain key actuation, switching device produces switch motion, and makes single light emitting module produce the effect of light and shade flicker.

[embodiment]

Please refer to Fig. 1 to shown in Figure 5,1 group of circuit board 7 that is located at electronic installation (not shown) of the utility model button is (convenient for illustrating, a part of circuit board only draws) on, comprise that housing 10, group are located at light conductor 2, resilient actuating spare 4, light emitting module 8 and switching device 6 in the housing 10.

Housing 10 number of comprising shape surfaces 11, run 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 fluting 13.

Light conductor 2 comprises main part 20, accepting groove 23 and is located at the pressure section 25 of main part 20 lower ends that wherein main part 20 comprises press surface 26 and outer wall 21, offers opening 22 on the outer wall 21.

Resilient actuating spare 4 is provided with pillar 42, auxiliary section 40 and the extended alignment pin 41 in 40 tops from the auxiliary section.

Light emitting module 8 comprises that flexible PCB 5 and group are located at the light-emitting diode 3 on the flexible PCB 5.Flexible PCB 5 roughly is " U " shape, and its top is provided with location hole 52, and the bottom is provided with weld part 53.Light-emitting diode 3 is located at location hole 52 sides on flexible PCB 5 tops.

The Actuator Division 61 that switching device 6 is provided with framework 60 and protrudes framework 60.

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, and wherein conductive path 70 is also connected with weld part 53 welding of flexible PCB 5, and the Actuator Division 61 of described switching device 6 connects with the contact-making surface 43 of resilient actuating spare 4.Light-emitting diode 3 on the flexible PCB 5 together is located in the accepting groove 23 of light conductor 2 with resilient actuating spare 4, and wherein the alignment pin 41 of resilient actuating spare 4 is fixed on flexible PCB 5 in the light conductor 2 by cooperating with location hole 52 on the flexible PCB 5.Light conductor 2 is located in the receiving space 12 of housing 10, and wherein press surface 26 dimplings of light conductor 2 are in the curved surfaces 11 of housing 10.The middle part of " U " shape flexible PCB 5 places opening 22 places of the fluting 13 and the light conductor 2 of housing 10, and fluting 13 matches bootable and limits the space of flexible PCB 5 with opening 22.

During use, push the press surface 26 of light conductor 2, make light conductor 2 compress resilient actuating spare 4, thereby make 4 elastic deformations of resilient actuating spare compress the Actuator Division 61 of switching device 6, make that like this light-emitting diode 3 conductings that are located on the flexible PCB 5 are luminous, through light conductor 2 conduction, make the surface light emitting of button 1.When button 1 not during pressurized, because the elastic force of switching device 6 Actuator Divisions 61 makes switching device 6 disconnect, it is not luminous to cause light-emitting diode 3 to open circuit, thereby button 1 surface is not luminous yet.

Really, light emitting module of the present utility model also can only comprise a light-emitting diode, and this moment, the pin of light-emitting diode can be directly and conductive path 70 electric connections of circuit board 7.And housing 10 also can be made an integral body with light conductor 2.
