embodiment:
See the accompanying drawing that the embodiment of the present invention is shown, hereafter the present invention will be described in more detail.But, the present invention can in different forms, the realization such as specification, and to should not be construed as by the restriction in the embodiment of this proposition.On the contrary, it is abundant and complete open in order to reach for proposing these embodiments, and makes more relevant those skilled in the art person understand scope of the present invention completely.In these accompanying drawings, for clearly visible, relative size may be zoomed in or out.
Please refer to Fig. 4 to Figure 11, the water proof and dust proof antenna of a kind of FPC form provided by the invention, for in a communication product, wherein, the shell 204 of this communication product is provided with perforation 206, and the water proof and dust proof antenna of this FPC form comprises: the first antenna part 201 and the second antenna part 202, first antenna part 201 are one whole structure, without cross cutting hole on it, and the first antenna part 201 is provided with tie point 203; The side of the second antenna part 202 is connected with the tie point 203 of the first antenna part 201, and opposite side is unsettled; This unsettled side bends through with the perforation 206 of communication product shell 204 is rear and is mounted in the one side of shell 204 of described communication product, and the another side of the shell 204 of communication product and the first antenna part 201 are close to.By the water proof and dust proof antenna of FPC form being pasted onto in the stickup district 205 of the shell 204 of communication product, avoiding because there is gap between the cross cutting hole of antenna and communication product, enhancing the functions of waterproof and dustproof of antenna area.
Wherein, the first antenna part 201 in the water proof and dust proof antenna of FPC form as known in Fig. 4-6 and the second antenna part 202 are all respectively an independently FPC, and the first antenna part 201 is antenna body, and the second antenna part 202 is antenna feed point; Because FPC plate has good bendability, the water proof and dust proof antenna of FPC form can be made to bend and be mounted on the shell 204 of communication product; During the water proof and dust proof antenna of FPC form and communication product shell are assembled as shown in Figures 4 to 7, independently the tie point 203 of the second antenna part 202 and the first antenna part 201 is by weld or the form of conducting resinl is interconnected, make to be combined with each other between two independent FPC, thus conducting circuit; And two independently FPC be together with each other, effectively improve the bulk strength of water proof and dust proof antenna.
As shown in Fig. 8 to Fig. 9, after this water proof and dust proof antenna is connected with communication product shell, second antenna part is in " Z " type or " C " type structure, and should the one side in the upper bottom surface of " Z " type or " C " type structure or bottom surface be connected with the tie point of described first antenna part, another side is unsettled; Described unsettled is passed described perforation and is mounted in the one side of the shell of described communication product, and another side and described first antenna part of the shell of described communication product are close to; And the distance between the upper bottom surface of " Z " type of being somebody's turn to do or " C " type structure and bottom surface equals the thickness of the shell of described communication product.
Certainly, in certain embodiments, other forms described such as the second antenna part of sheet metal component etc. can be directly " Z " type or " C " type structure, and should the one side in the upper bottom surface of " Z " type or " C " type structure or bottom surface be connected with the tie point of described first antenna part, another side is unsettled; Described unsettled is passed described perforation and is mounted in the one side of the shell of described communication product, and another side and first antenna part of the shell of communication product are close to; And the distance between the upper bottom surface of " Z " type of being somebody's turn to do or " C " type structure and bottom surface equals the thickness of the shell of communication product, makes the second antenna part of this " Z " type or " C " type structure snap in communication product shell, realizes rapid-assembling.
In addition, as Figure 10 to Figure 11, the first antenna part 201 be combined with each other and the second antenna part 202 are assembled on the shell 204 of communication product.Wherein, first antenna part 201 bonds mutually with the stickup district 205 of communication product shell, the second antenna part 202 through communication product shell perforation 206 through the perforation 206 of communication product shell, and bends by the second antenna part 202, and is adhesively fixed at the opposite side of communication product shell.Further, the feedback point of the second antenna part is connected with other communication products.
Fixed by the water proof and dust proof antenna of above-mentioned FPC form and the assembling of communication product shell, effectively improve the overall tightness of communication product; The present invention adopts the water proof and dust proof antenna without cross cutting hole, avoid the inside of water, dust granule intrusion communication product shell, under compact structure condition, the waterproof and dustproof function of communication product at antenna area can be realized, thus effectively improve functional characteristic and the life-span of communication product.
In addition, we it should further be appreciated that, the present invention is not as limit, and the water proof and dust proof antenna of relevant FPC form that the present invention relates to and the stickup of communication product shell are not limited only to the bonding mode that the present invention proposes, and the mode can also pasted with other mutual assembling is grouped together; And the first antenna part and the second antenna part not only can by weld or the form of conducting resinl is connected, other fixed form can also be used, and the form of the syndeton of this water proof and dust proof antenna can also be applied to the antenna as metalwork form or other materials form, as long as bulk strength that both combine can be strengthened and can conducting circuit, thus improve the functions of waterproof and dustproof of antenna.
Obviously, those skilled in the art can carry out various change and distortion to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and distortion belong in the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these changes.
