Key 32 contacts, and the other end of the side switch 20 passes through side switch hole 101 and stretches out outside shell 10.
Preferably, in the present embodiment, the shell 10 includes front housing 11 and rear shell 12, and the rear shell 12 is by described the
One cavity 102 is isolated with the second cavity 103 to be separated, and the via hole 104 is set in rear shell 12.The side switch hole 101 is by front housing
11 enclose with rear shell 12 and are configured to, and mainboard 40 and the elastic slice connecting with mainboard 40 50 are provided in second cavity 103, described
Tongue piece 33 is contacted with elastic slice 50, so that FPC plate 31 and mainboard 40 are connected.By rear shell 12 by first cavity 102 and
The isolation of two cavitys 103 separates, and can prevent the liquid such as water from entering in the second cavity 103, and then prevent mainboard 40 because of liquid such as water
The situation of effect and generation short circuit or certain disablers, causes economic loss to user.
Since the side switch 20 is movable part, by 20 pressing keys 32 of side switch, due to being deposited between side switch 20 and shell 10
In gap, the liquid such as water are easily accessible in the second cavity 103, cause mainboard 40 occur because of the effect of the liquid such as water short circuit or certain
The situation of a little disablers.Therefore the second cavity 103 needs to guarantee the case where being fully sealed, avoiding into water generation.Traditional technology
On tongue piece be directly to be extended outward to form from one end lateral margin of FPC plate, since the thickness of FPC plate itself can be formed at via hole
One step will form and have the gap, lead to waterproof failure when pasting waterproof membrane.And tongue piece 33 of the invention wherein a lateral margin with
FPC plate 31 connects, and forms gap between the other lateral margins and FPC plate 31 of tongue piece 33, when pasting waterproof membrane, waterproof membrane can glue
It is attached in a complete plane, so that sealing effect is more preferable, more preferably, waterproofing grade has reached IPX7 grades to waterproof performance
Waterproof can effectively solve the problems, such as the waterproof failure as caused by the thickness of FPC plate itself in the prior art.
Preferably, the rear shell 12 includes the first rear shell 121 and the second rear shell 122, first rear shell 121 and second
Rear shell 122 encloses the second cavity 103 for being configured to sealing.
Preferably, the front of the FPC plate 31 is provided with waterproof membrane 60, and the waterproof membrane 60 covers the via hole 104,
Avoid the problem that the liquid such as water from via hole 104 enter the second cavity 103 in and lead to waterproof failure.
Preferably, waterproof gum 70 is provided between the back side and rear shell 12 of the FPC plate 31.FPC plate 31 passes through waterproof
Gum 70 is fixed in rear shell 12.It is fixed in such a way that waterproof gum 70 is pasted, it is easy to assembly and low in cost, can have
Effect reduces production cost.It should be noted that the FPC plate 31 and the fixed form of rear shell 12 are not limited thereto, in this hair
In bright other preferred embodiments, the FPC plate 31 can also be fixed with rear shell 12 in such a way that screw is fixed.
Preferably, as shown in figure 3, figure 4 and figure 5, the FPC plate 31 includes side plate 311 and connect with the side plate 311
Substrate 312.One lateral margin of the substrate 312 from the side plate 311 integrally extends to form, the FPC plate 31 by one at
Type forms, and structure is simple, easy to process.
Preferably, as shown in fig. 6, the FPC component 30 further includes stiffening plate 34, the key 32 divides with stiffening plate 34
It is not set on the tow sides of side plate 311, the tongue piece 33 is set on substrate 312.Due to FPC plate 31 material more
Softness, therefore by the way that stiffening plate 34 is arranged on the side plate 311 of FPC plate 31, the hard of FPC plate 31 is improved by stiffening plate 34
Degree convenient for assembling, and avoids when user is by 20 pressing keys 32 of side switch, so that FPC plate 31 is mobile, pressing is caused to be lost
It loses.
Preferably, the one side of the stiffening plate 34 is fixed on side plate 312 by double-sided adhesive 35, the stiffening plate 34 it is another
It is fixed in rear shell 12 also through double-sided adhesive 35 on one side.It is easy to operate since double-sided adhesive 35 is easy to obtain, pass through double-sided adhesive 35
It is fixed, cost, and small volume can be effectively saved, can meet that electronic equipment is lighter, thinner requirement, improves user's body
It tests.Certainly, the fixed form of the stiffening plate 34 is not limited thereto, can be in other preferred embodiments of the invention
It is fixed in such a way that screw is fixed.
Preferably, the key 32 uses Waterproof push-button, and waterproofing grade can reach IPX7 waterproof.The key 32 passes through
The mode of welding is fixed on the FPC plate 31.The key 32 have pad, due to pad exposure in air not by
Protection, short circuit can still be occurred by being immersed in the water, and therefore, for effective waterproof, pad of the invention and key periphery pass through dispensing
Mode be fixed on FPC plate 31, can further improve waterproof effect.
In addition, key 32 of the invention is directly to contact with side switch 20, user experience is can be improved in good hand touch.And traditional skill
Key meets water generation short circuit in order to prevent in art, and barrier water enters in the second cavity, it will usually be arranged between key and side switch
The material of the soft materials such as silica gel seriously affects feel, and side switch pressing is stiff, and rebound soft inability, and feel is very poor.
