Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that being defined in the embodiment of the present invention according to the rectangular coordinate system established in Fig. 1：Just positioned at Y-axis
The side in direction is defined as front, and the side positioned at Y-axis negative direction is defined as rear.
The present invention provides a kind of remote controler, and referring to figs. 1 to Fig. 4, in one embodiment, which includes shell 1 and electricity
Road plate 2.The shell 1 includes front housing 11.Front housing 11 is provided with accommodating chamber (being filled by circuit board 2, do not mark), the circuit board
2 are located in the accommodating chamber.The circuit board 2 is convexly equipped with multiple metal domes 22 (for attached drawing towards the front housing 11 on one side
Succinctly, part metal dome 22 is illustrated only in figure).The region of the multiple metal domes 22 of the correspondence of the front housing 11 is respectively formed with more
The key zone 3 of a elasticity.The key zone 3 generated when being compressed by external force elastic deformation with support corresponding pressure metal dome 22,
So that 22 elastic deformation of metal dome and contacted with circuit board 2 and by circuit board 2 circuit be connected.The key zone 3
Restore to the original state when the external force disappears so that key zone 3 is separated with metal dome 22 so that the reinstatement of metal dome 22 and
So that the circuit on circuit board 2 disconnects.
Circuit board 2 is first contained in front housing 11 by the remote controler of this case during installation, so that circuit board 2 and front housing
11 become an entirety, so that more compact structure；Then subsequent installation is carried out again, this will make the peace of entire remote controler
Efficiency is filled to improve.
In the present embodiment, specifically, the front housing 11 include formed accommodating chamber arch portion 111 and with the arch portion
111 extensions 112 for connecting and extending into the accommodating chamber.It is formed and is held between the extension 112 and the arch portion 111
It receives slot 113, so that the periphery of the circuit board 2 is inserted into, and the circuit board 2 is fixed in the accommodating chamber of the front housing 11.
Certainly, circuit board 2 can be fixed in the accommodating chamber of front housing 11 by kinds of schemes, and the scheme of the present embodiment is only
It is one of which, in other embodiments, is also possible to be spirally connected by bolt circuit board 2 and front housing 11；Or in front housing 11
Arch portion 111 is equipped with buckle, is blocked the edge of circuit board 2 by buckling, so that 2 phase of circuit board is fixed；It again or will be electric
Road plate 2 is bonded or welded on the arch portion 111 of front housing 11；Or pass through the arch portion 111 of front housing 11 and the week of circuit board 2
The frictional force of edge and circuit board 2 and front housing 11 is fixed.These can realize the effect that circuit board 2 is fixed with 11 phase of front housing
Fruit.
In this city embodiment, the front housing 11 is flexible soft part, such as silica gel, TPU or TPE etc.；To make
