Existing press-key structure, comprise the support that is fixedly arranged on the casing and offers key hole, the rubber cushion that offers through hole, the through hole of being offered on the rubber cushion be used for more firm with elastic mounting on support, it is continuous and relative with the key switch position with rubber cushion that keycap passes key hole, and the key switch circuit board interior with being located at casing is electrically connected.Press keycap, the keycap that is pressed compresses key switch, finishes button operation thereby key switch can import the signal of telecommunication into circuit board.When key switch is the directionkeys switch, press the direction that keycap just can be controlled cursor in the portable mobile termianl screen.
The inventor finds in realizing process of the present utility model, offer through hole on the rubber cushion in the existing press-key structure, so the performance of existing press-key structure antistatic is poor, during the keycap of pressing keys, finger can contact with keycap, friction mutually, the static of human body can import circuit board into by keycap and through hole, influences the performance of circuit board, may cause the circuit board can't operate as normal when serious.
The utility model content
The utility model embodiment provides a kind of electrostatic prevention key structure and a kind of portable mobile termianl, has solved the poor technical problem of performance of existing press-key structure antistatic.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
This electrostatic prevention key structure, comprise the support that is fixedly arranged on the casing and offers key hole, the rubber cushion that is provided with stud bump and with the relative key switch in described stud bump position, described key hole is passed at the top of described stud bump, and described stud bump and described rubber cushion are the integral type hermetically-sealed construction.
This portable mobile termianl comprises casing and is located at the electrostatic prevention key structure that the above-mentioned the utility model embodiment on the described casing is provided.
Compared with prior art, the utility model provides the arbitrary technical scheme in the technique scheme to have following advantage:
Because stud bump and rubber cushion are the integral type hermetically-sealed construction, not only stud bump be connected with rubber cushion more firm, be convenient to the one-shot forming manufacturing, and do not offer through hole on the rubber cushion, avoided the press-key structure external static electrification to import circuit board into by through hole, avoided the harmful effect of static, so solved the poor technical problem of the performance of existing press-key structure antistatic to the circuit board performance.
Description of drawings

Fig. 2 for after the assembling of electrostatic prevention key structure that embodiment of the present utility model shown in Figure 1 provided the master look schematic diagram;
Fig. 3 is the analyse and observe enlarged diagram of Fig. 2 along the A-A line;
Fig. 4 is the enlarged diagram of B part among Fig. 3.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
The utility model embodiment at first provides a kind of electrostatic prevention key structure of not offering through hole.
As shown in Figure 1, the electrostatic prevention key structure that the utility model embodiment is provided, comprise the support 2 that is fixedly arranged on the casing and offers key hole 1, the rubber cushion 5 that is provided with stud bump 3 and as shown in Figure 3 and Figure 4 the key switch 4 relative with stud bump 3 positions, key hole 1 is passed at the top of stud bump 3, and stud bump 3 is the integral type hermetically-sealed construction with rubber cushion 5.
Because stud bump 3 is the integral type hermetically-sealed construction with rubber cushion 5, not only stud bump 3 be connected with rubber cushion 5 more firm, be convenient to the one-shot forming manufacturing, and do not offer through hole on the rubber cushion 5, avoided the press-key structure external static electrification to import circuit board into by through hole, influence the performance of circuit board, so solved the poor technical problem of the performance of existing press-key structure antistatic.
See also Fig. 2, Fig. 3 and Fig. 4, offer concave station 6 on the rubber cushion 5, stud bump 3 is tubular and is located at the bottom surface of concave station 6, and key switch 4 is embedded in the stud bump 3.Concave station 6 has increased the elasticity of the rubber cushion 5 around the stud bump 3 on the one hand, because stud bump 3 is tubular and key switch 4 is embedded in the stud bump 3, and it is more compact to make that key switch 4 combines with stud bump 3, the sensitivity of press-key structure is better on the one hand.
The junction of the bottom surface of stud bump 3 and concave station 6 is provided with the elastic buffer portion 7 of bending.Elastic buffer portion 7 not only is convenient in the button operation process, reset rapidly after stud bump 3 is pressed, and pressing keys projection 3 is more laborsaving, has improved the feel of button operation.
The top of stud bump 3 also is arranged with the keycap 8 of straw hat shape, also is installed with the decoration 9 of ring-type on the key hole 1, and decoration 9 is passed at the top of keycap 8, and its edge is embedded between decoration 9 and the concave station 6.Keycap 8 has the effect of protection stud bump 3, and decoration 9 not only can block keycap 8, avoids keycap 8 to come off from stud bump 3, and can improve the outward appearance of whole press-key structure.Keycap 8 comprises directionkeys keycap and PC numerical key keycap 10 as shown in Figures 2 and 3 in the present embodiment.
Present embodiment medium-height trestle 2 is preferably the steel disc support.Support 2 elasticity that steel disc is made are relatively good, are convenient to press-key structure and reset.
The utility model embodiment also provides a kind of portable mobile termianl that is provided with electrostatic prevention key structure.
This portable mobile termianl comprises casing and is located at the electrostatic prevention key structure that the above-mentioned the utility model embodiment on the casing is provided.
With above-mentioned the utility model embodiment in like manner, the electrostatic prevention key structure in the portable mobile termianl that the utility model embodiment is provided has the identical technique effect with above-mentioned the utility model embodiment, and then also can solve identical technical problem.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
