Portion 3446, the first elastic arm 3442 and the second elastic arm 3444 are separately positioned on 3446 both ends of interconnecting piece, the first elastic arm 3442
It is opposite with the second elastic arm 3444 to be arranged in parallel, the first elastic arm 3442 compress button FPC20 extend to 32 direction of button that
End, and the second elastic arm 3444 is inserted into the bayonet 326 of button 32, to prevent button 32 toward 322 side of press section backwards to button 32
To movement.Meanwhile there is the groove 14 being adapted to the first fixed part 342 on shell 10, have raised 142, first in groove 14
Fixed part 342 has opening 3422, and the first fixed part 342 is fixed in groove 14, and protrusion 142 passes through opening 3422, passes through
The first fixed part 342 is blocked in the design of groove 14, to prevent holder 34 from being moved along the length direction of shell 10.And it is set in groove 14
It sets protrusion 142 and carrys out the opening 3422 across the first fixed part 342, to prevent button 32 toward 322 side of press section towards button 32
To movement.Therefore, the assembling structure of the holder 34 of the present embodiment and shell 10 and button 32, can effectively prevent about 32 button
It moves left and right, plays the role of fixing button 32 well.
In the present embodiment, the first elastic arm 3442 can also have towards the inclined bending part in 3444 direction of the second elastic arm
34422, it prevents the first elastic arm 3442 from being deviated towards backwards to 3444 direction of the second elastic arm, enhances the stability of holder 34.
In the present embodiment, the bending interconnecting piece 3446 of rack body 346 and the first fixed part 342 can also have enhancing recessed
Slot 3462, enhancing groove 3462 design can reinforced support ontology 346 and the first fixed part 342 hardness, reduce rack body
346 and first fixed part 342 deformation, to enhance the stability of holder 34.
The assembling sequence of the terminal device 1 of the present embodiment is as follows：
Button FPC20 is pasted onto in the locating slot of shell 10, then by the press section 322 of button 32 towards shell 10
Mounting portion 324 is packed into button 32 by outside across mounting hole 12, and the first fixed part 342 of holder 34 is then directed at shell
Groove 14 on 10, the second fixed part 344 the first elastic arm 3442 alignment button FPC20 extend to 32 direction of button that
End, the bayonet 326 of the second elastic arm 3444 alignment button 32 of the second fixed part 344, finally down by holder 34 by holder
34 fix on the housing 10.
In the present embodiment, rack body 346 is according to the structure of 32 mounting portion 324 of button and bayonet 326 and according to demand
Respective design notch 3464 so that user can press holder 34 down, and the second elastic arm 3444 of holder 34 is made to be inserted into bayonet
326。
In the present embodiment, dismounting mouth 348 can be also set between rack body 346 and mounting portion 324, after sale convenient for the later stage
When repair, extracting tool is inserted into dismounting mouth 348 and extracts holder 34, it is easy to operate.
