It is a perspective view which expands and shows the terminal connection opening and its periphery in a front side cabinet. It is a perspective view which expands and shows the terminal connection opening and its periphery in a front side cabinet and a back side cabinet. FIG. 2 is a view corresponding to FIG. 1 according to a comparative example.

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

  FIG. 2 shows a mobile phone 1 as an electronic device according to an embodiment of the present invention, and this mobile phone 1 includes a front side cabinet 3 as a housing into which a display unit (not shown) is fitted on the front side. Yes. As shown also in FIG. 5, the back side of the front side cabinet 3 is covered with the back side cabinet 4, and the entire side and back are covered with the rear cover 5.

  As shown in FIG. 4, for example, an oval terminal connection opening 3 a that exposes an internal external connection terminal (not shown) is formed on the corner 1 a side of the upper end of the front cabinet 3. In accordance with this, as shown in FIG. 5, the back side cabinet 4 also has a rectangular back side opening 4a. Similarly, as shown in FIG. 2, a rectangular cover side opening 5 a is also opened at the upper end of the rear cover 5. As shown in FIG. 4, an inner recess 3b that is recessed along the curvature of the corner 1a is provided on the corner 1a side of the cover side opening 5a.

  These openings are covered with a terminal cover 10. As shown in FIG. 3, the terminal cover 10 includes a cover main body 11 having a shape corresponding to the cover-side opening 5a and constituting a part of the appearance. The cover body 11 is made of, for example, the same material as the rear cover 5.

  As shown in FIG. 3C, an oval packing portion 12 that covers the terminal connection opening 3 a in a sealed manner is integrally formed on the inner surface of the cover body 11. The packing part 12 is made of silicon rubber or the like. However, the present invention can also be applied to a terminal cover that does not have a waterproof structure in which the packing portion 12 is not integrally molded.

  As shown in FIG. 1, the cover main body 11 has a locking portion 13a at one end in the longitudinal direction that engages with an engaging portion 4b formed in the back cabinet 4 corresponding to the periphery of the terminal connection opening 3a in the closed state. The insertion part 13 is formed.

  And the hole 16 for a connection along the corner part 1a is formed by the corner part inner surface of the back side cabinet 4 which covers the inner side recessed part 3b, and the inner side recessed part 3b. In the inner recess 3b in the middle of the connection hole 16, a protrusion 17 is provided so as to increase in height toward the back side (left and right outer sides). A strip-shaped connecting portion 14 extends on the opposite side of the cover body 11 from the insertion portion 13. A flange portion 15 a that is hooked on the protrusion 17 when the cover body 11 is pulled out in an open state is integrally formed at the distal end portion 15 of the connection portion 14. The terminal cover 10 is prevented from coming off at the periphery of the connection hole 16 by the engagement between the flange 15a and the protrusion 17. The connection portion 14 is curved along the curvature of the connection hole 16 when no force is applied. Since the distal end portion 15 is tapered toward the distal end, the base strength of the flange portion 15a can be secured while reducing resistance such as friction when the connection portion 14 is inserted.

  As a feature of the present invention, as shown in FIG. 1 (b), at the tip portion 15 of the connecting portion 14, when the flange portion 15a is caught by the projection 17, the rear side cabinet on the opposite side to the flange portion 15a. 4 is formed integrally with a bulging portion 15b (indicated by hatching in a partially enlarged view of FIG. 3B) that abuts the inner surface of the connecting hole portion 16 constituted by 4.

  Next, the operation of the bulging portion 15b will be described in comparison with a comparative example.

  In the comparative example shown in FIG. 6, the bulging portion 15 b is not provided at the tip portion 15. In this comparative example, as shown in FIG. 6 (b), the cover body 11 is pulled out, the tip portion 15 of the connection portion 14 rises in the connection hole portion 16, and the flange portion 14 a comes into contact with the protrusion 17. To prevent it from coming off. At this time, a slight gap C is provided between the inner surface of the connection hole 16 and the connection portion 14 in order to ensure ease of insertion and removal.

  When the connection portion 14 is pulled by applying further force, the connection portion 14 has an appropriate flexibility. Therefore, the connection portion 14 is deformed relatively easily so that the collar portion 14a exceeds the protrusion 17 and the terminal cover 10 is pulled out. End up.

  On the other hand, in the embodiment of the present invention, as shown in FIG. 1 (b), when the flange portion 15 a is caught by the protrusion 17 in the open state of the terminal cover 10, the bulging portion 15 b comes into contact with the inner surface of the connection hole portion 16. Therefore, even if the connection portion 14 is further pulled, the flange portion 15a is not easily deformed. For this reason, it is prevented reliably that the collar part 15a slips out from the protrusion 17.

  As shown in FIG. 1A, the connecting portion 14 is inserted so as to extend along the connecting hole 16 in the closed state. In the opened state shown in FIG. Since the bulging portion 15b is surely brought into contact with the inner surface of the connecting hole portion 16 when the flange portion 15a comes into contact with the projection 17 due to the influence of the pulling-up direction and the bending direction of the connecting portion 14, the bulging portion 15b The deformation preventing effect due to is improved.

  Therefore, according to the mobile phone 1 according to the present embodiment, when the connecting portion 14 extending from the cover main body 11 is hooked on the protrusion 17 on the periphery of the connecting hole 16 and the hook 15a is hooked on the protrusion 17. By providing a bulging portion 15b that contacts the inner surface of the connecting hole 16 on the opposite side of the flange portion 15a and prevents the connecting portion 14 from coming off, the terminal cover 10 is prevented from coming off and has a high prevention effect. Can be a thing.
