FIG. 10 is an exploded view of the mobile phone 1 according to the embodiment of the present invention as seen from the back side. A battery cover insertion port 3 a for inserting and removing the battery cover 10 is formed at the lower end of the housing 3. The battery cover 10 includes a cover body 11 made of a resin molded product and a decorative cover 12 that covers the cover body 11. A pair of antenna elements (not shown) are printed on the outer periphery of the cover body 11, and the antenna elements extending from each of the pair of antenna elements are antenna connectors as a pair of left and right first engaging portions (first connectors). 13 is connected to a metal terminal 13 a provided on the terminal 13. A USB connector 14 as a third engagement portion (second connector) is provided in the center of the pair of left and right antenna connectors 13. A pair of left and right bulging portions 3b as first engaged portions is provided on the periphery of the battery cover insertion port 3a. The main board 6 on the back side of the pair of bulging portions 3b is provided with antenna connection terminals 6a connected to the pair of antenna connectors 13, respectively. A USB terminal 6b as a third engaged portion to which the USB connector 14 is connected is provided at the center of the left and right of the antenna connection terminal 6a. The distance between the left and right inner surfaces of the pair of bulging portions 3 b is slightly larger than the distance between the left and right outer surfaces of the pair of antenna connectors 13. As for the part which the bulging part 3b and the antenna connector 13 contact | abut first, it is desirable for at least one of both to have an inclined surface.

  A waterproof packing 15 as a second engaging portion is attached to the upper surface of the battery cover 10. The waterproof packing 15 includes a packing body 15a made of a resin molded product, and a silicon rubber 15b covering the outer periphery of the packing body 15a. In front of the bulging portion 3b at the periphery of the battery cover insertion port 3a, a frame-shaped packing abutting surface 3c as a second engaged portion is formed, in which the silicon rubber 15b of the waterproof packing 15 abuts. In order to ensure waterproofness, it is desirable that the silicon rubber 15b and the packing contact surface 3c are engaged in a sealed manner. That is, the engagement between the silicon rubber 15b and the packing contact surface 3c is positioned more tightly and accurately than the engagement between the first-stage bulge 3b and the antenna connector 13.

  In addition to these two-stage positioning, it is advantageous to perform positioning by engaging the USB terminal 6b and the USB connector 14 between these positioning.

  Next, the operation of the mobile phone 1 according to this embodiment will be described. 7 is a view corresponding to FIG. 3 when the second stage engagement is performed, FIG. 8 is a view corresponding to FIG. 3 when the third stage engagement is performed, and FIG.

The antenna connector 13 is inserted while positioning in the left-right direction by loosely contacting the left and right outer end faces of the antenna connector 13 with the left and right inner end faces of the pair of bulging portions 3b. At this time, since the left and right intervals between the two are set so as to have a margin, positioning at the time of insertion is extremely easy.

  Next, when the tip of the USB connector 14 whose tip protrudes beyond the pair of antenna connectors 13 approaches the opening of the USB terminal 6b and then is further inserted, as shown in FIG. Further engagement is performed by being inserted into the USB terminal 6b. This engagement is positioned tighter in the left-right direction than the first-stage engagement.

  Next, when further pushed, as shown in FIGS. 8 and 9, the tip of the USB connector 14 is completely connected to the USB terminal 6b, and the pair of antenna connectors 13 are connected to the antenna connection terminal 6a. At this time, the silicon rubber 15b of the waterproof packing 15 contacts the packing contact surface 3c and comes into close contact with the packing contact surface 3c, thereby positioning the battery cover 10 accurately and reliably. Since the engagement of the waterproof packing 15 is tighter than the engagement of the pair of antenna connector 13 and USB connector 14, the battery cover 10 is accurately positioned at a fixed position.

  Thereafter, the fixing screw 16 shown in FIG. 10 is inserted into the screw insertion hole 11 a of the battery cover 10 and fastened to the screw hole 3 d of the housing 3 to fix the battery cover 10. At this time, since the battery cover 10 is accurately fixed, it is very easy to tighten the fixing screw 16.

  As described above, since the battery cover 10 is positioned in three stages, it is only necessary to gradually tighten the engagement from the first stage to the third stage. The waterproof packing 15 is accurately and reliably positioned.

  Further, since these three-stage positioning is performed by the antenna connector 13, the USB connector 14, and the waterproof packing 15 that are necessary for other applications, it is not necessary to provide a dedicated positioning member.

  Therefore, according to the mobile phone 1 according to the present embodiment, positioning when attaching the battery cover 10 with a simple configuration can be facilitated.
