  However, the conventional portable terminal has a complicated shape such as providing a rib above the fixing screw to prevent the fixing screw from coming off. In addition, a mold configuration is complicated in a structure in which a U-shaped through hole is provided in the housing and a strap is passed through the through hole.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a strap attachment structure with a simple configuration and a small number of parts.

  In order to achieve the above object, in the present invention, a shaft portion for attaching a strap to a nut for fastening a coupling screw for fixing two cabinets is provided.

Specifically, in the first invention,
In mobile devices that can be attached with straps,
A first cabinet having a strap insertion recess and a nut press-fit hole adjacent to the strap insertion recess;
A second cabinet having a screw insertion hole corresponding to the nut press-fitting hole and coupled to the first cabinet;
A screw that is inserted into the screw insertion hole and is fastened to a nut that is press-fitted into the nut press-fitting hole, thereby including a coupling screw that couples the first cabinet and the second cabinet;
The nut includes a shaft portion that protrudes into the strap insertion recess and on which the strap can be hung.

  According to the above configuration, since the shaft portion for strapping the nut is provided, the number of parts is reduced, and the shaft portion is arranged at the coupling portion between the first cabinet and the second cabinet. improves. Further, the shape of the strap insertion recess is simplified, and the mold configuration is simplified.

  As described above, according to the present invention, the coupling screw for coupling the first cabinet and the second cabinet is fastened to the nut press-fitted into the nut press-fitting hole, and the strap insertion recess provided in the nut is inserted. Since the strap is hung on the shaft protruding to the side, the strap mounting structure can be simplified and the number of parts can be reduced.

FIG. 4 is an enlarged cross-sectional view taken along a line II in FIG. 3. It is a disassembled perspective view which shows the 2nd housing | casing of the mobile telephone which concerns on embodiment of this invention. It is a front view of the 2nd case. It is the IV-IV line expanded sectional view of FIG. It is a perspective view which expands and shows a nut, waterproof packing, and a coupling screw.

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

  FIG. 2 is an exploded perspective view showing the second housing 1 of the mobile phone as the mobile terminal according to the embodiment of the present invention, and FIG. 3 is a front view of the second housing 1. Although not shown in detail, in the mobile phone, for example, a first housing having a display portion and a second housing 1 are connected to each other so as to be foldable around a hinge portion 1a. The 2nd housing | casing 1 is provided with the front side cabinet 2 as a 2nd cabinet, and the back side cabinet 3 as a 1st cabinet. The front-side cabinet 2 includes an operation unit 4 having a plurality of keys on the front side. The front-side cabinet 2 and the back-side cabinet 3 are fastened with a plurality of connecting screws 5 so as to be connected.

1 is an enlarged cross-sectional view taken along line II in FIG. 3, and FIG. 4 is an enlarged cross-sectional view taken along line IV-IV in FIG. The rear cabinet 3 has a strap insertion recess 3a formed on the upper left side. A nut press-fitting hole 3b having a circular cross section is formed on the front side so as to be adjacent to the strap insertion recess 3a. On the other hand, in the front side cabinet 2, a circular screw insertion hole 2a corresponding to the nut press-fitting hole 3b is formed concentrically with respect to the nut press-fitting hole 3b. A ring groove 2b is provided on the surface side of the screw insertion hole 2a, and a counterbore 2c is formed on the surface side. Then, the coupling screw 5 is fastened to the nut 6 that is press-fitted into the nut press-fitting hole 3b that is inserted into the screw insertion hole 2a, so that the back side cabinet 3 and the front side cabinet 2 are coupled. An O-ring 9 is inserted into the coupling screw 5, and this O-ring 9 is designed to exert a waterproof function in the ring groove 2 b. FIG. FIG. As a feature of the present invention, the nut 6 has a round bar-shaped shaft portion 7 that protrudes into the strap insertion recess 3a and can be hooked with the strap. The shaft portion 7 is made of metal, for example, like the nut 6, and may be formed integrally with the nut 6, or may be bonded to the nut 6, welded, or crimped. When bonding or the like, the shaft portion 7 may be formed of a high-strength resin molded product or the like. The tip of the shaft portion 7 is inserted into a tip insertion hole 3c concentric with a nut press-fitting hole 3b formed in the strap insertion recess 3a. The intermediate outer periphery of the nut 6 is formed with an annular recess 6a that is recessed with respect to other parts. When the nut 6 is press-fitted into the nut press-fitting hole 3b, a resin portion forming the nut press-fitting hole 3b is fitted into the annular recess 6a so that the nut 6 is prevented from coming off.

  Further, a waterproof packing 8 made of an annular rubber or the like is sandwiched between the bottom surface of the nut 6 and the bottom surface of the nut press-fitting hole 3b.

  (1) Thus, by integrally providing the shaft portion 7 for hooking the strap on the nut 6, the number of parts is reduced and the shaft portion is arranged at the joining portion between the back side cabinet 3 and the front side cabinet 2. As a result, the strength is improved. Further, the shape of the strap insertion recess 3a is simplified, and the mold configuration is simplified.

  (2) Since the waterproof packing 8 is sandwiched between the bottom surface of the nut 6 and the bottom surface of the nut press-fitting hole 3b, waterproofing between the strap insertion recess 3a and the nut press-fitting hole 3b can be achieved with a simple configuration. Done.

  Therefore, according to the mobile phone according to the present embodiment, the coupling screw 5 for coupling the rear side cabinet 3 and the front side cabinet 2 to the nut 6 press-fitted into the nut press-fitting hole 3 b is fastened, and the strap provided on the nut 6 Since the strap is hung on the shaft portion 7 protruding into the insertion recess 3a, the strap mounting structure can be simplified and the number of parts can be reduced.
