FIG. 2 is a perspective view of the folded mobile phone when the end portion on the side opposite to the hinge portion is viewed with the back cover 3 covering the battery housing portion 5 housing the secondary battery 4 removed. ing. As can be seen from FIGS. 1 and 2, a connection terminal 6 to which the connector head of the charger is connected when charging the secondary battery 4 is provided at the end of the lower housing 2 on the side opposite to the hinge part. ing. In addition, as shown in FIG. 2, the lower housing 2 is provided with a strap mounting portion 7 that is exposed when the back cover 3 is removed.

  3 and 4 are enlarged perspective views of the strap mounting portion 7. This strap mounting portion 7 is integrally formed with the lower housing 1 by a member such as ABS resin (ACRYLONITRILE, BUTADIENE, STYRENE resin), as shown in FIG. In addition, a bifurcated protrusion 10 provided in a shape protruding from the lower housing 2 toward the back cover 3 side, and a pull-out hole for pulling out the strap hooked on the protrusion 10 to the outside of the lower housing 2 Part 11. The width of the drawing hole 11 is substantially the same as the width of the strap drawn from the drawing hole 11.

  Further, the strap mounting portion 7 is provided with a predetermined length so that the end portion of the strap can be easily passed through the projecting portion 10 when the projecting portion 10 is passed through the end portion of the strap having a ring shape as shown in FIG. (I.e., processed to a curvature corresponding to the curvature of the end portion of the strap). In addition, the R processing wall portion 12 is tapered so that the outer diameter gradually decreases along the thickness direction of the lower housing 2, and the end portion of the ring-shaped strap is attached to the strap. The part 7 is guided without resistance.

  As shown in FIG. 4, the projecting portion 10 has a pair of strap fixing arm portions 13 projecting left and right. The connecting portion 14 of the projecting portion 10 with the lower housing 2 has a width smaller than the width of the strap fixing arm portion 13 as shown by an arrow in FIG.

Further, FIG. 5 shows a perspective view of the front surface of the strap mounting portion 7 as seen from a slightly upward direction. As can be seen from FIG. 5, each strap fixing arm portion 13 of the protruding portion 10 has a shape gradually narrowed from the connection portion 14 side to the anti-connection portion 14 side. In the meantime, an inverted triangular gap portion 16 indicated by a dotted line in FIG. 5 is formed.

[Process until strap attachment]
Next, when attaching a strap to such a strap attachment part 7, the back cover 3 is first removed from the lower housing | casing 2 shown in FIG. As a result, the strap mounting portion 7 is exposed as shown in FIG.

  Next, as shown in FIGS. 2 and 4, the projecting portion 10 of the strap mounting portion 7 passes through one end portion 20 a of the strap 20 having a ring shape. At this time, the R processing wall portion 12 of the strap mounting portion 7 is tapered so that the outer diameter gradually decreases along the thickness direction of the lower housing 2. Between the strap fixing arm portion 13 and the R processed wall portion 12, an inverted triangular gap portion 16 indicated by a dotted line in FIG. 5 is provided. Furthermore, each strap stop arm part 13 of the protrusion part 10 has a shape gradually narrowed from the connection part 14 side to the anti-connection part 14 side. For this reason, the one end portion 20a of the strap 20 that is in the shape of a ring is smoothly guided between the projecting portion 10 and the R processed wall portion 12, and the one end portion 20a is not resistant to the projecting portion 10. Can pass through.

  Next, the strap is pulled in the anti-hinge direction indicated by the arrow in FIG. 4 with the protruding portion 10 passing through the one end portion 20a of the strap 20 thus formed in a ring shape. As described with reference to FIG. 3, the connecting portion 14 with the lower housing 2 of the protruding portion 10 has a width smaller than the width of the strap fixing arm portion 13. For this reason, when the strap 20 is pulled in the anti-hinge portion direction with the projecting portion 10 passing through the one end portion 20a of the ring-shaped strap 20, the one end portion 20a of the strap 20 is as shown in FIG. To the position of the connecting portion 14 of the protruding portion 10, and the one end 20 a is hooked on the connecting portion 14 of the protruding portion 10. Further, when the one end portion 20a of the strap 20 is hooked on the connecting portion 14, the one end portion 20a becomes elliptical by further pulling the strap 20 in the anti-hinge portion direction, and the one end portion 20a of the strap 20 is It will be in the state pulled out from the drawing hole 11 of the mounting portion 7.

  In this state, the diameter of the one end portion 20a of the strap 20 is constricted to substantially the same size as the diameter of the connecting portion 14 of the protruding portion 10. Even if the strap 20 is pulled in the direction (= the protruding direction of the protruding portion 10), the one end portion 20a of the strap 20 is hooked on each strap fixing arm portion 13 protruding to the left and right of the protruding portion 10, and in the normal movement of the strap 20, The strap 20 is not easily detached from the strap mounting portion 7.

  Next, with the strap 20 attached to the strap attaching portion 7, the back cover 3 is attached to the lower housing 2 as shown in FIG. As a result, the strap mounting portion 7 is covered with the back cover 3 in a state where the one end portion 20a of the strap 20 is pulled out from the pull-out hole portion 11 of the strap mounting portion 7, and the mobile phone becomes invisible. .

  Further, as described above, the width of the drawing hole 11 is substantially the same as the width of the strap 20 drawn from the drawing hole 11. For this reason, when the one end portion 20a of the strap 20 is pulled out from the pullout hole portion 11, the pullout hole portion 11 is hidden by the one end portion 20a. 11 becomes difficult to visually recognize.

  Here, in the state where the strap 20 is attached to the strap attaching portion 7 and the back cover 3 is attached to the lower housing 2, the strap 20 is directed toward the back cover 3 (= anti-thickness direction of the lower housing 2). When pulled, the one end 20a of the strap 20 abuts against the back cover 3, and there is a concern that the back cover 3 may be easily detached from the lower housing 2.

However, in the case of the strap mounting portion 7 of this embodiment, the one end portion 20a of the attached strap 20 is pressed by the pair of strap fixing arm portions 13 of the protruding portion 10. For this reason, even if the strap 20 attached to the strap attachment part 7 is pulled in the direction of the back cover 3 in a state where the back cover 3 is attached to the lower housing 2, the one end 20 a of the strap 20 with respect to the back cover 3.

Therefore, even if the strap 20 is pulled in the anti-thickness direction of the lower housing 2 (= the protruding direction of the protruding portion 10), each strap fixing arm portion 13 in which the one end 20 a of the strap 20 protrudes to the left and right of the protruding portion 10. The strap 20 can be firmly fixed to the strap mounting portion 7.

  In addition, when the back cover 3 is attached to the lower housing 2, the strap attachment portion 7 is almost entirely covered, and the strap attachment portion 7 is not visible from the appearance of the mobile phone, and the drawer hole Since the width of the portion 11 is substantially the same as the width of the one end portion 20a of the strap 20 drawn out from the drawing hole portion 11, the drawing hole portion 11 is hidden by the one end portion 20a. This drawer hole 11 is also difficult to see from the appearance of the mobile phone. As described above, since the strap attaching portion 7 is not conspicuous in the appearance of the mobile phone, the design of the mobile phone can be improved. Further, it is possible to prevent inconvenience that the strap mounting portion 7 hinders the degree of freedom in designing the mobile phone.

  Further, when removing the strap 20 attached to the strap attaching portion 7, the diameter of the one end portion 20 a of the strap 20 that is constricted to the same size as the diameter of the connecting portion 14 of the protruding portion 10 is set. Then, the protrusion 10 is expanded to a diameter larger than that of the strap fixing arm 13, and one end 20 a of the strap 20 is removed from the strap fixing arm 13. Also in this case, the strap 20 can be easily detached from the strap mounting portion 7 with one touch.

In addition, as a strength standard of the strap mounting part today, it is required to maintain a strength that the strap mounting part is not broken even if the strap mounted on the strap mounting part is pulled with a force of 150 N for 1 minute. It is added that the applicant of the present invention made a prototype experiment of the strap mounting portion 7 and was able to obtain an experimental result sufficiently satisfying the strength standard.
