  Thus, in the conventional portable terminal device, it is necessary to provide a hole through which the antenna passes when extending and contracting, and the antenna is outside the waterproof region of the waterproof packing in order to ensure waterproof performance. For this reason, if the waterproof sheet paste part for paste of a waterproof sheet is provided in the periphery of a rechargeable battery accommodating part in order to waterproof a rechargeable battery itself, an antenna will be arranged on the outside by that much. For this reason, there exists a problem that a rechargeable battery with a large width cannot be provided.

  The present invention has been made in view of such a point, and an object of the present invention is to allow the telescopic antenna to be disposed while reliably waterproofing the rechargeable battery without increasing the width of the mobile terminal. There is.

  In order to achieve the above object, in the present invention, the antenna receiving recess, the waterproof sheet attaching portion, and the waterproof packing are made as close as possible to each other.

Specifically, the portable terminal of the first invention is:
A front cabinet that houses the display on the front,
A back side cabinet fitted to the back side of the front side cabinet;
A rechargeable battery housed in the battery compartment of the back cabinet;
A rear cover covering the back side cabinet;
Waterproof packing sandwiched between the contact surfaces of the front cabinet periphery and the back cabinet periphery;
An antenna housing recess recessed outside the waterproof region by the waterproof packing on the rear cover side at the periphery of the back side cabinet;
A waterproof sheet affixing part formed on the periphery of the battery housing part on the back side of the back side cabinet;
A margin of margin is affixed to the waterproof sheet affixing part, and the waterproof sheet covering the rechargeable battery in the battery housing part in a sealed manner;
And a telescopic antenna that is retractably accommodated in the antenna accommodating recess.

And in the side view, the antenna housing recess is disposed between the adhesive margin of the waterproof sheet and the waterproof packing,
In the rear view, the adhesive margin extends to the vicinity of the antenna receiving recess, and the waterproof packing and the antenna overlap.

  According to said structure, since an antenna accommodation recessed part exists in the waterproof area | region of a waterproof packing, even if it covers an antenna with a rear cover so that expansion and contraction is possible, water does not enter inside. Further, since the antenna position is provided on the waterproof packing when viewed from the back, and the adhesive margin is close to the antenna receiving recess, useless space is saved and the width of the portable terminal does not increase.

  As described above, according to the present invention, the antenna receiving recess is arranged between the adhesive margin of the waterproof sheet and the waterproof packing in the side view, and the waterproof margin is extended to the vicinity of the antenna receiving recess in the rear view. Since the antenna and the antenna overlap with each other, the telescopic antenna can be disposed while reliably waterproofing the rechargeable battery without increasing the width of the portable terminal.

It is the I section expanded sectional view of FIG. It is the perspective view which looked at the mobile telephone concerning the embodiment of the present invention from the front side. It is the disassembled perspective view which looked at the mobile telephone from the back side. It is the perspective view which looked at the mobile telephone of the state where the back cover was removed from the back side. It is the VV sectional view taken on the line of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  2 is a perspective view of the mobile phone 1 as a mobile terminal according to the embodiment of the present invention as seen from the front side, and FIG. 3 is an exploded perspective view of the mobile phone 1 as seen from the back side. 4 is a perspective view of the mobile phone 1 with the rear cover removed, as viewed from the back side, and FIG. 5 is a cross-sectional view taken along line VV in FIG. The mobile phone 1 includes a front cabinet 3 that accommodates a display unit 2 on the front. In the front side cabinet 3, a rectangular plate-shaped metal frame 3a is insert-molded, and a display unit 2 having a liquid crystal display, a touch panel, or the like is accommodated on the front side. A flat packing pressing portion 3b is formed in a rectangular frame shape on the back side of the resin frame of the front cabinet 3 covering the metal frame 3a.

  FIG. 1 is an enlarged cross-sectional view of a portion I in FIG. On the back side of the front side cabinet 3, a back side cabinet 4 made of, for example, a resin molded product is coupled with bolts or the like. A rectangular dish-shaped rear cover 5 is detachably covered on the back side. In the back side cabinet 4, a frame-shaped packing receiving groove 4a is recessed corresponding to the packing pressing portion 3b. When a rectangular plate-shaped waterproof packing 6 is fitted in the packing receiving groove 4a and the front cabinet 3 and the rear cabinet 4 are joined, the waterproof packing 6 exhibits a waterproof effect. When viewed from the back, a battery housing portion 4b having a rectangular shape in back view is formed inside the packing housing groove 4a in the back side cabinet 4. A rectangular plate-shaped rechargeable battery 7 is accommodated in the battery accommodating portion 4b. A flat waterproof sheet attaching portion 4c is provided in a frame shape on the periphery of the battery housing portion 4b. Then, a rectangular waterproof sheet 9 that is slightly larger than the rechargeable battery 7 is attached to the waterproof sheet attaching part 4 c by a frame-like double-sided tape 8. That is, the adhesive margin 9a at the periphery of the waterproof sheet 9 is attached to the waterproof sheet attaching part 4c, so that the rechargeable battery 7 in the battery housing part 4b is covered in a sealed manner. As described above, the waterproof packing 6 and the waterproof sheet 9 provide a waterproof function on the mating surfaces of the front cabinet 3 and the back cabinet 4 and the battery housing 4b. On the other hand, the waterproof function is not exhibited between the back side cabinet 4 and the rear cover 5.

  Then, outside the waterproof region by the waterproof packing 6 on the rear cover 5 side at the periphery of the back side cabinet 4, an antenna receiving recess 10 having, for example, an arc-shaped inner surface is recessed so as to extend vertically along the battery receiving portion 4b. . The telescopic antenna 11 is housed in the antenna housing recess 10 so as to be telescopic. For example, the telescopic antenna 11 has a portion in which a round steel as a core material and a metal pipe that covers the round steel are overlapped. When the length of the antenna receiving recess 10 is long, it is not necessary to have multiple layers of metal pipes, which is advantageous in that the outer diameter of the telescopic antenna 11 can be reduced and the width of the mobile phone 1 is not increased. As shown in FIG. 1, the antenna housing recess 10 has a circular arc shape whose inner diameter is slightly larger than the maximum diameter of the telescopic antenna 11, and the rear side wall portion 10 a along the peripheral wall of the battery housing portion 4 b includes the telescopic antenna. Since it extends to the outside in the width direction from the center of 11, it is difficult to forcibly take out the telescopic antenna 11 by inserting a nail or the like between the telescopic antenna 11. The telescopic antenna 11 is covered with a resin pipe-shaped antenna cover 12 having the same color as the back side cabinet 4. For this reason, the appearance may be improved, and the gap between the rear side wall portion 10a may be reduced. As shown in FIGS. 3 and 4, the tip of the antenna cover 12 is supported by an antenna fixing portion 13, and the antenna fixing portion 13 is fixed to the back side cabinet 4 by screws 14. By electrically connecting a main board (not shown) to the antenna fixing unit 13, a signal received by the telescopic antenna 11 can be transmitted to the main board. A knob portion 15 made of the same synthetic resin as that of the rear cabinet 4 is attached to the tip of the telescopic antenna 11 so that it can be pinched and pulled out when the telescopic antenna 11 is expanded and contracted. When covered with the rear cover 5, the antenna cover 12 and the antenna fixing portion 13 are hidden, and only the knob portion 15 is exposed.

  As shown in FIG. 1, the antenna housing recess 10 is housed in a narrow position in the thickness direction between the adhesive margin 9 a of the waterproof sheet 9 and the waterproof packing 6 in a side view. Moreover, the adhesive allowance 9a extends in the vicinity of the antenna accommodating recess 10 in the rear view, and the waterproof packing 6 and the telescopic antenna 11 overlap. That is, the antenna accommodating recess 10, the adhesive margin 9a, and the waterproof packing 6 are arranged as close to each other as possible.

  As described above, since the antenna housing recess 10 is provided outside the waterproof region of the waterproof packing 6, even if the telescopic antenna 11 is covered with the rear cover 5 in a telescopic manner, water does not enter the interior.

  In addition, since the position of the telescopic antenna 11 is provided on the waterproof packing 6 when viewed from the back, and the adhesive margin 9a is close to the antenna receiving recess 10, the width of the mobile phone 1 does not increase.

  Therefore, according to the mobile phone 1 of the present invention, the telescopic antenna 11 can be arranged while the rechargeable battery 7 is reliably waterproofed.

The present invention may be configured as follows with respect to the above embodiment.

  That is, in the above embodiment, the antenna accommodating recess 10 is provided on the left and right side surfaces of the mobile phone 1, but the position is not particularly limited, and may be the upper and lower side surfaces. Even in this case, the antenna housing recess 10 may be provided along the peripheral wall of the battery housing 4b.

  In the above embodiment, the mobile terminal is the mobile phone 1, but if it has a telescopic antenna and a rechargeable battery, a PHS (Personal Handy-phone System), PDA (Personal Digital Assistant), personal computer, mobile tool An electronic dictionary, a calculator, a game machine, or the like may be used.
