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

  FIG. 1 is an exploded perspective view of a mobile phone charger, and FIG. 2 is a vertical side view of the mobile phone charger. As shown in FIGS. 1 and 2, the charger main body 11 is composed of a flat rectangular lower cover 12 and a flat rectangular upper cover 13 formed of a synthetic resin material. The lower cover 12 is integrally provided with a peripheral wall 15 on the outer peripheral portion of the bottom surface portion 14. On the left and right inner surfaces of the peripheral wall 15 at both ends in the longitudinal direction of the lower cover 12, engaging portions 16 having steps are provided. The upper cover 13 is integrally provided with a peripheral wall 18 on the outer peripheral portion of the upper surface portion 17. Engagement claw portions 19 project from the left and right inner surfaces of the peripheral wall 18 at both ends in the longitudinal direction of the upper cover 13 so as to correspond to the engagement portion 16, and the upper cover 13 is positioned and pressed against the lower cover 12. By doing so, the engaging claw portion 19 and the engaging portion 16 are elastically engaged, and the upper cover 13 is coupled to the lower cover 12.

  Further, as shown in FIG. 3, through holes 20 are provided at the corners of the bottom surface portion 14 on one end side of the lower cover 12, and the through holes 20 are formed at the corners of the upper surface portion 17 of the upper cover 13. A boss 21 having a screw hole 21a is provided. The lower cover 12 and the upper cover 13 are fixed by inserting a fixing screw 22 from the through hole 20 side of the lower cover 12 and screwing it into the screw hole 21a of the upper cover 13.

  As shown in FIGS. 1 and 2, a rectangular battery 23 is accommodated in the lower cover 12, and the battery 23 is positioned and fixed by a plurality of protrusions 24 protruding from the bottom surface portion 14 of the lower cover 12. Has been. On the upper surface of the battery 23, a rectangular electronic component board unit 25 substantially equal to the planar shape of the battery 23 is laminated. A plurality of electronic components 26 are mounted on the upper surface of the electronic component substrate unit 25, that is, the side opposite to the surface in contact with the battery 23, and the electronic components 26 protrude from the substrate 25a. An LED 27 is fixed to one side of the electronic component board unit 25. This LED 27 indicates that charging is in progress, and is exposed to the outside from notches 28 provided corresponding to the peripheral walls 15 and 18 of the lower cover 12 and the upper cover 13.

  A charging connector 29 that can be connected to a charging terminal of a mobile phone (not shown) is provided on one end side of the electronic component board unit 25, and a connecting terminal 31 that can be connected to an AC charging connector 30 described later is provided on the other end side. It has been. The charging connector 29 is protected by a connector main body 32 made of a synthetic resin material. The connector main body 32 is in a state where the lower cover 12 and the fitting holes 33 provided in the peripheral walls 15 and 18 of the upper cover 13 are engaged. Projecting to the outside of the charger body 11.

  Therefore, since the charging connector 29 is provided at a position where it is not stacked with the battery 23 and the electronic component board unit 25 and between the lower cover 12 and the upper cover 13, the charging connector 29 is thicker than the charger main body 11. The design of the thin structure does not affect the.

  Further, as shown in FIG. 4, on one side of the charging connector 29, projecting pieces 34 are integrally provided on the outer surfaces of the peripheral walls 15 and 18 of the lower cover 12 and the upper cover 13. The pivot pins 35 that face each other are integrally projected. A connector cap 36 that covers the charging connector 29 is pivotally supported by these pivot pins 35 so as to be openable and closable. That is, the connector cap 36 has a box shape having an opening on one side surface, and an engagement hole 37 is provided at one end of the connector cap 36 so as to freely engage with the pivot pin 35.

  The connector cap 36 can be rotated (opened / closed) about the pivot pin 35 as a fulcrum, and can be protected by covering the charging connector 29 when closed. Further, as shown in FIGS. 4 to 6, a strap hole 38 is provided at a corner on the fulcrum side of the connector cap 36, and a ball chain type strap 39 or a strap 40 with a cranikan ring is inserted and suspended from the mobile phone. Be able to.

  As shown in FIG. 2, the connection terminal 31 connected to the AC charging connector 30 is covered with an AC charging connector receiving portion 41. The AC charging connector receiving portion 41 is a rubber square tube, and is provided with an insertion hole 42 into which the terminal portion 30a of the AC charging connector 30 is inserted. Further, an engagement rib 43 is provided on the outer peripheral portion of the AC charging connector receiving portion 41, and this engagement rib 43 is engaged with a notch portion 44 provided on the peripheral wall 18 of the upper cover 13, and an insertion hole 42 opens to the outside of the charger body 11.

  Accordingly, since the AC charging connector receiving portion 41 is provided at a position where it is not stacked with the battery 23 and the electronic component board unit 25 and between the lower cover 12 and the upper cover 13, the AC charging connector receiving portion 41 is charged. It is designed to have a thin structure that does not affect the thickness of the main body 11.

  A rectangular recess 45 is provided on the upper surface of the upper cover 13 over substantially the entire area. An escape hole 46 is provided at the bottom of the recess 45 so as to face the electronic component 26 of the electronic component board unit 25 and to be fitted to the electronic component 26. In other words, the charger main body 11 is designed to be thin by overlapping the electronic component 26 mounted so as to protrude upward from the upper surface of the electronic component board unit 25 and the upper cover 13 by the escape hole 46. .

  Further, a solar cell panel 48 is fitted into the recessed portion 45 of the upper cover 13 with the light receiving surface 47 facing upward, and is bonded and fixed to the upper cover 13. The solar cell panel 48 is electrically connected to the electronic component substrate unit 25 and the battery 23 via lead wires (not shown). When the light receiving surface 47 receives solar energy, the energy is converted into electric energy, The battery 23 in the charger main body 11 is charged.

  As shown in FIG. 7, the AC charging connector 30 is connected to an AC connection plug 50 via a cord 49 to constitute an AC charging unit 51. The AC charging connector 30 is connected to the connection terminal 31, and the AC charging unit 51 is connected. By connecting the connection plug 50 to an AC outlet, the battery 23 can be charged by an AC power source.

  The mobile phone charger configured as described above has a structure in which the battery 23, the electronic component substrate unit 25, and the solar cell panel 48 are housed in a stacked state inside the charger main body 11. Moreover, the charging connector 29 and the AC charging connector receiving portion 41 are provided between the lower cover 12 and the upper cover 13 at a position where they are not stacked with the battery 23, the electronic component substrate unit 25, and the solar cell panel 48. Therefore, the charger main body 11 can be reduced in size and thickness. Moreover, since it does not contain a dry battery, it is lightweight, and it is convenient to carry by being suspended from a mobile phone using the ball chain strap 39 or the strap 40 with a cranikan ring.

  In the embodiment, the mobile phone has been described. However, the present invention is not limited to the mobile phone, and can be used for charging a mobile device such as a personal computer.
