For foregoing of the present invention and other purpose, feature and advantage can be become apparent more, preferred embodiment cited below particularly, and conjunction with figs. is elaborated as follows.
Description of drawings
The planar inverted F-shape antenna and the circuit board of mobile phone that are respectively common in the present mobile phone shown in Figure 1A and the 1B make up the preceding schematic perspective view that reaches after making up.
Shown in Figure 2 is when planar inverted F-shape antenna is squeezed suddenly, the schematic perspective view after the skew of metal shell foot.
Being respectively shown in Fig. 3 A and the 3B according to the schematic perspective view that reaches before its antenna and the circuit board combination in a kind of mobile communications device of one embodiment of the invention after making up.
Embodiment
Being respectively shown in Fig. 3 A and the 3B according to the schematic perspective view that reaches before antenna and the circuit board combination in a kind of mobile communications device of one embodiment of the invention after making up.Please be simultaneously with reference to Fig. 3 A and 3B, mobile communications device 300 comprises casing (not shown), circuit board 310 and antenna 320, and circuit board 310 all is built in the casing with antenna 320.Circuit board 310 has two power I/O and connects 312,314 and two auxiliary fixing member 316,318 of face.Two auxiliary fixing member 316,318 are placed in the top that the power I/O connects face 312,314 respectively, and are electrically connected with it.In this embodiment, auxiliary fixing member the 316, the 318th, made by the rubber-like metal material, and its production method be with sheet metal through repeatedly bending, make it have the section of M type.Further, auxiliary fixing member 316 has the first contact-making surface 316a and the second contact-making surface 316b, forms groove 316c among the first contact-making surface 316a and the second contact-making surface 316b, makes the metal shell foot of antenna 320 can be connected in it; Similarly, auxiliary fixing member 318 also has the first contact-making surface 318a and the second contact-making surface 318b, forms groove 318c among the first contact-making surface 318a and the second contact-making surface 318b, and the metal shell foot of antenna 320 can be sticked in it.
In this embodiment, when metal shell foot 322 is connected to auxiliary fixing member 316, metal shell foot 322 can firmly be sticked among the first contact-making surface 316a and the formed groove 316c of the second contact-making surface 316b, two bending parts that are metal shell foot 322 can contact with the first contact-making surface 316a and the second contact-making surface 316b line respectively, so, metal shell foot 322 comprises two line contact area B, C with auxiliary fixing member 316 contacted parts.Similarly, metal shell foot 324 also comprises two line contact area B, C with auxiliary fixing member 318 contacted areas.Because the contact area between metal shell foot 322,324 and the auxiliary fixing member 316,318 has increased, so can avoid being squeezed when causing the displacement of metal shell foot when antenna, the not good problem of signal transmission efficiency takes place easily.In addition, when antenna 320 and circuit board 310 were combined, metal shell foot 322,324 can be connected to respectively in the auxiliary fixing member 316,318, therefore, also has the function of self-calibrating (self-alignment).Like this, all help to guarantee the relation that is electrically connected between antenna 320 and the circuit board 310, to reach the purpose of good signal transmission.
In this embodiment, be to be the explanation that example is done with the planar inverted F-shape antenna in the concealed antenna, certainly, antenna 320 also can be the microstrip type antenna (microstrip antenna) or the antenna of other form, and the present invention does not impose any restrictions this.
In sum, mobile communications device of the present invention is that the power I/O at circuit board connects and installs one on the face respectively and have the auxiliary fixing member of M type profile, and the metal shell foot of antenna is connected in the above-mentioned auxiliary fixing member.When antenna and circuit board group were fitted together, the metal shell foot can be connected in the corresponding auxiliary fixing member, and the two contacted area comprises two line contact areas.Like this, can reach the effect of self-calibrating, and can guarantee to have between antenna and the circuit board stable and excellent contact, thereby reach the purpose of good signal transmission by this design.
Though the present invention discloses as above with reasonable embodiment; yet it is not in order to limit the present invention; any person of ordinary skill in the field; without departing from the spirit and scope of the present invention; can do a little change and improvement, so protection scope of the present invention should be with being as the criterion that claim was defined.
