It states after pre-tightening block 400, is locked on the backboard 120.
The button assembly 300 includes bracket 310, stiffening plate 320, (the Flexible Printed of flexible circuit board 330
Circuit, FPC), first seal 340, second seal 350 and side key 360.Wherein,
The bracket 310 is set between the support plate 140 and the side plate 160.The stiffening plate 320, flexible circuit
Plate 330 and the second seal 350 are fixedly installed in the bracket 310.The first seal 340 is set to the bracket
Between 310 and the side plate 160.The side key 360 is installed on the side plate 160, and can be towards close to or far from institute
The direction for stating flexible circuit board 330 is mobile.The flexible circuit board 330 is equipped with the isolation 332 for triggering keypress function
(DOME), when the side key 360 under the action of the pressing force that user applies towards close to the flexible circuit board 330 side
To when movement, it can touch, and squeeze the isolation 332, generate trigger signal, and then realize its corresponding function (for example, bright
The regulatory function of degree, volume etc.).
Specifically, in the present embodiment, the bracket 310 is in " I " fonts comprising upper plate 311 and the upper plate 311
The lower plate 313 being oppositely arranged, and vertically connect the connecting plate 315 of the upper plate 311 and the lower plate 313；The soft electricity
Road plate 330 is installed between the connecting plate 315 and the preload block 400；The second seal 350 is set to the soft electricity
Between road plate 330 and the bracket 310.Isolation 332 on the corresponding flexible circuit board 330 of the connecting plate 315 is equipped with
Opening 317 triggers the isolation 332 so that the side key 360 can pass through the opening 317.The stiffening plate 320
Intensity for bracket 310 described in reinforcement.The first seal 340 is with the second seal 350 by flexible
Sealing foam is made.The first seal 340 is for being sealed the junction of the bracket 310 and the side plate 160.
The second seal 350 is for being sealed the junction of the flexible circuit board 330 and the bracket 310.

Add the pretightning force towards 160 direction of side plate, so that with the side plate 160 to compress described first close for the bracket 310
Sealing 340.
Specifically, in the present embodiment, the preload block 400 is wedge block, that is, the support plate 140 with it is described pre-
The surface that tight block 400 cooperates is inclined-plane, and by the free end of the support plate 140, (support plate 140 is far from institute on the inclined-plane
State one end of backboard 120) it is tilted towards the direction for pre-tightening block 400.
Further, as shown in figure 3, dismounting for convenience, in the present embodiment, sliding slot is additionally provided on the backboard 120
122；The bracket 310 is slidably mounted in the sliding slot 122, so that the bracket 310 can be towards close to or far from institute
State the direction sliding of side plate 160.
When assembling, first the flexible circuit board 330 is installed in the bracket 310, then the bracket 310 is installed on
Between the support plate 140 and the side plate 160；Then, the preload block 400 is installed on the bracket 310 and the branch
Between fagging 140, and the mainboard 200 is supported in 140 top of support plate；Finally, the screw 500 is sequentially passed through
The mainboard 200 and the preload block 400, and be locked on the backboard 120.During sealed, the preload block 400 exists
When the gap being inserted between the support plate 140 and the bracket 310, it can apply to the bracket 310 towards the side plate 160
The extruding force in direction, the bracket 310 is under the action of the extruding force along the sliding slot 122 towards the side plate 160
Direction is mobile, since the side plate 160 is fixed, so, when the bracket 310 is mobile towards the direction of the side plate 160
When, the first seal 340 between the bracket 310 and the side plate 160 can be squeezed, so that the first seal
340 occur elastic deformation, and the first seal 340 is fitted tightly over the bracket 310 and the side plate 160
Together, the sealing effect of the bracket 310 and the junction of the side plate 160 has been effectively ensured, and then the branch is effectively ensured
The waterproof effect of the junction of frame 310 and the side plate 160.
When disassembly, the screw 500 is screwed out, when the elastic deformation of the first seal 340 restores, gives the bracket
310 apply the extruding force for being directed away from 160 direction of side plate.The bracket 310 is directed away from institute along the sliding slot 122
The direction for stating side plate 160 is mobile, and squeezes the preload block 400, while the preload block 400 is squeezed power, by
The thrust in upper (direction far from the backboard 120), the preload block 400 move up, and by the support plate 140 with it is described
Deviate between bracket 310.
The technical solution of the present embodiment pre-tightens block 400 by setting, while realizing that mainboard 200 is fixed, gives bracket
310 provide the pretightning force towards 160 direction of side plate, and first seal 340 and bracket 310 and side plate 160 can be made close
Fit together, the sealing effect of the junction of bracket 310 and side plate 160 be effectively ensured, so be effectively ensured bracket 310 with
The waterproof effect of the junction of side plate 160；Compared to the existing technical side pre-tightened by structures such as screws to bracket 310
Case, technical solution of the present invention structure is relatively simple, and cost is relatively low, and can effectively save the inner space of mobile terminal.
It is noted that the shape for pre-tightening block 400 is not limited to above-mentioned shape, it can also be rectangle (such as Fig. 4
It is shown) or right-angled trapezium (as shown in Figure 5), the technical effect of above-mentioned guarantee waterproof effect equally may be implemented.
