Abstract

The utility model relates to the technical field of electronic remote controller structures, in particular to a remote controller with a novel air discharge structure. The remote controller comprises a remote controller casing, a PCB board, a key sheet, a name plate, a name plate, a key sheet and a PCB board which are sequentially overlapped in the remote controller casing, a plurality of key-press bosses are arranged on the name plates, a plurality of circular through holes are opened on the key sheets, the key-press bosses and the circular through holes are in corresponding overlapping, and a plurality of key-press air discharge holes are opened on the PCB boards, and after the remote controller is assembled, the key-press air discharge holes are in corresponding overlapping with the circular through holes and the key-press bosses. After employing the structure, the remote controller with a novel air discharge structure has the advantages of simple structure, is capable of avoiding the problem that the front name plate is sunk, and employs the air discharge structure.

Description

A kind of remote controller with novel exhaust structure

Technical field

The utility model relates to the electronic romote-controller technical field of structures, refers in particular to a kind of remote controller with novel exhaust structure.

Background technology

For the button that makes remote controller can better use and reset, usually in the remote controller exhaust structure being arranged all. traditional exhaust structure is by offer the purpose that air discharge duct reaches exhaust on the key sheet of inscription backboard face, yet, because the mould towards air discharge duct is every row's integral manufacturing, when requiring to cancel one of them button, the air discharge duct of this button can not be cancelled thereupon.Thereby cause that when high temperature test this key position depression causes the bad of outward appearance.

Summary of the invention

That the purpose of this utility model provides at the deficiencies in the prior art part is a kind of simple in structure, can avoid before the bad phenomenon of inscription plate depression, adopt the remote controller of vent structure.

For achieving the above object, the utility model includes: remote controller housing, pcb board, key sheet, inscription plate. and inscription plate, key sheet, pcb board is overlapping successively is installed in the remote controller housing, on the inscription plate, be provided with a plurality of button boss bags, have a plurality of manholes on the key sheet, button boss bag is corresponding one by one overlapping with manhole, also offer a plurality of button steam vents on described pcb board, after the assembling, the button steam vent is corresponding one by one overlapping with manhole and button boss bag.

After adopting said structure, the utility model is offered steam vent in the position of each button on PCB, change the begin to rehearse mode of air drain of key sheet into PCB the begin to rehearse mode of pore, like this, each the raising mould on the inscription plate and each punching die on the key sheet can independently be made.When taking down when not required, the bad phenomenon of inscription plate depression before can overcoming like this.

Embodiment

Shown in Fig. 1-4, the utility model includes: remote controller housing 10, pcb board 20, key sheet 30, inscription plate 40. inscription plate 40, key sheets 30, pcb board 20 is overlapping successively is installed in the remote controller housing 10, on inscription plate 40, be provided with a plurality of button boss bags 41, have a plurality of manholes 31 on the key sheet 30, button boss bag 41 is corresponding one by one overlapping with manhole 31, on described pcb board 20, also offer a plurality of button steam vents 21, after the assembling, button steam vent 21 is corresponding one by one overlapping with manhole 31 and button boss bag 41.On described remote controller housing 10, be provided with a plurality of screwed holes 11, and on pcb board 20 the corresponding aperture 22 that passes for screw that has, aperture 22 backs and the remote controller housing 10 interior screwed hole screw threads 11 that holding screw passes on the pcb board 20 are connected.

Steam vent 21 is offered in the position of the utility model below each button boss bag 41 of pcb board 20, like this, change the begin to rehearse mode of air drain of key sheet 30 into pcb board 20 the begin to rehearse mode of pore 21, like this, each the raising mould on the inscription plate 40 and each punching die on the key sheet 30 can independently be made.When taking down when not required, the bad phenomenon of inscription plate depression before can overcoming like this.

Claims
