Specific embodiment
In the following description, for purposes of illustration, in order to provide the comprehensive understanding to one or more embodiments, explain
Many details are stated.It may be evident, however, that these embodiments can also be realized in the case of not having these details.
In other examples, for the ease of describing one or more embodiments, known structure and equipment illustrate in block form an.
For describing the electroconductive elastic sheet of the present invention and the electronic equipment being provided with this electroconductive elastic sheet in detail, below with reference to accompanying drawing
The specific embodiment of the present invention is described in detail.
Fig. 1 and Fig. 2 respectively illustrates the signal that electroconductive elastic sheet according to embodiments of the present invention is under two kinds of different conditions
Structure.
As Fig. 1 and Fig. 2 is jointly shown, the electroconductive elastic sheet of the embodiment of the present invention, the fixed part 1 including horizontal structure and solid
Determine the elastic arm of force 2 of portion 1 elastic connection, and the limiting section being arranged on the elastic arm of force 2 end；Fixed part 1 is arranged oriented
The fixed block 4 that limiting section direction is dug, is provided with spacing draw-in groove 5 in the medium position of fixed block, in the setting of the end of limiting section
There is the spacing dop 3 of " T " shape structure, spacing dop 3 is fastened in corresponding spacing draw-in groove 5, thus two freedom to shell fragment
End (limiting section and fixed part) is fastened and connected.
Wherein, spacing dop 3 further include to constitute "T"-shaped horizontal holding section and perpendicular to holding section and with elasticity
The extension that the arm of force connects, spacing draw-in groove is " ⊥ " the shape structure being adapted with spacing dop, horizontal including composition " ⊥ " shape
Enter groove 51 and perpendicular to enter groove 51 stopper slot 52；Spacing dop is configured to be passed through by entering groove 51 in holding section
Afterwards, move upwards in the presence of the elastic arm of force, extension is fastened in stopper slot 52.
Specifically, Fig. 1 shows that the spacing dop 3 of electroconductive elastic sheet according to embodiments of the present invention and spacing draw-in groove 5 are not detained
State before conjunction；Fig. 2 shows the spacing dop 3 of electroconductive elastic sheet according to embodiments of the present invention and spacing draw-in groove 5 fastening
State afterwards.
In a specific embodiment of the present invention, spacing draw-in groove 5 is " ⊥ " character form structure, including entrance groove 51 and limit
