Further, the power terminal 5 is provided at a position close to the left groove 7 on the surface of the mobile terminal device 6 where the power terminal 5 is provided, whereas the power terminal 15 of the mobile terminal device 16 is provided. The power terminal 15 is provided at a position close to the right groove 17 on the surface. Further, the rib 12 of the mobile terminal device 6 is provided at the center lower portion of the groove portion 7, whereas the rib 22 of the mobile terminal device 16 is provided at the center upper portion of the groove portion 17.

  Therefore, when the user or the like attaches the battery pack 2 to the mobile terminal device 16, the user or the like turns the battery pack 2 upside down with respect to the case of attaching the battery pack 2 to the mobile terminal device 6 (the B surface is on the upper side). Further, it is rotated 90 degrees in the direction opposite to the clockwise direction on a plane parallel to the bottom surface of the battery insertion portion 14 of the portable terminal device 16.

  Then, the user or the like places the battery pack 2 obliquely with respect to the battery insertion portion 14 of the mobile terminal device 16 so that the position of the claw portion 3 in the battery pack 2 matches the position of the groove portion 17 in the mobile terminal device 16. The claw part 3 is engaged with the groove part 17 and inserted.

  Further, when the battery pack 2 is pushed from the rear surface, the surface of the battery pack 2 having the claw portion 3 and the wall of the battery insertion portion 14 abut against each other, and the battery pack 2 is The rotational movement is performed so that the angle formed by the two widest planes and the bottom surface of the battery insertion portion 14 is small.

  In addition, when the inclined surface is formed in the middle of the rib 22, the inclined surface of the rib 22 serves as a guide, and the portion of the claw portion 3 that contacts the rib 22 is smoothly lowered along the inclined surface. The claw portion 3 of the battery pack 2 is smoothly fitted into the groove portion 17 in the mobile terminal device 16. Further, the lower portion of the groove 31 in the claw portion 3 serves as an engaging portion guided by the inclined surface of the rib 22.

  FIG. 8 is an explanatory diagram showing a state in which the battery pack 2 is attached to the mobile terminal device 16. As shown in FIG. 8A, the battery pack 2 is attached to the mobile terminal device 16. FIG. 8B shows a cross section cut so as to cut the groove 31 (in the example shown in FIG. 8A, a cross section cut along the cutting line S2). In the example shown in FIG. 8B, the left side is the A surface side of the battery pack 2, and the right side is the B surface side. FIG. 8C is a cross-sectional view that is cut so as to cut the groove 31 and shows the vicinity of the claw portion 3 (the portion surrounded by a circle in FIG. 8B). In the example shown in FIG. 8C, the left side is the A surface side of the battery pack 2, and the right side is the B surface side.

  As shown in FIG. 8C, the claw portion 3 is fitted in the groove portion 17, and the rib 22 is fitted in the groove 31 in the claw portion 3.

  Further, when a user or the like tries to attach the battery pack 2 to the mobile terminal device 16 upside down (that is, the battery pack 2 is attached to the mobile terminal device 16 with the B surface facing down (the A surface facing up)). When trying to), the notched portion of the claw portion 3 hits the rib 22. The width of the claw portion 3 (the height of the portion protruding from the rectangular parallelepiped that forms the battery pack 2) is determined when the battery pack 2 is inserted into the battery insertion portion 14 of the portable terminal device 16 in the reverse direction. However, the length of the battery insertion portion 14 can be prevented from falling into the battery insertion portion 14 from the wall of the battery insertion portion 14 (the wall opposite to the wall on which the groove portion 17 is provided). That is, the height of the claw portion 3 of the battery pack 2 is such that when the battery pack 2 is inserted into the battery insertion portion 14 upside down, the engaging portion in the claw portion 3 abuts on the rib 22 in the battery insertion portion 14. The battery pack 2 is sometimes set to a height that does not fit into the battery insertion portion 14.

  Therefore, since the length of the battery pack 2 in the longitudinal direction is relatively longer than the length of the battery insertion portion 14 in the longitudinal direction when the claw portion 3 hits the rib 22, the battery pack 2 and the battery insertion portion 14 are separated from each other. The battery pack 2 does not fit into the battery insertion portion 14 and is in a floating state due to interference. Note that the term “relatively long” means that the sum of the length in the longitudinal direction of the rectangular parallelepiped portion of the battery pack 2 and the width of the claw portion 3 is compared with the length in the longitudinal direction of the battery insertion portion 14. .

  Therefore, when the battery pack 2 is attached to the mobile terminal device 16 in a normal orientation, the battery pack 2 is smoothly attached to the battery insertion portion 14. Even if the battery pack 2 is to be mounted on the mobile terminal device 16 upside down, the claw portion 3 hits the rib 22 and the battery pack 2 does not fit into the battery insertion portion 14.

  In this embodiment, the battery pack 2 can be mounted on the mobile terminal device 6 and the mobile terminal device 16 that have different power terminal positions. That is, the battery pack 2 can be shared and used for portable terminal devices having different power terminal positions.

  Specifically, for example, in a mobile terminal device in which a power supply terminal is provided on the left side in the longitudinal direction, the battery pack 2 is mounted with the A side facing up, and the power supply terminal is on the right side in the longitudinal direction. The battery pack 2 can be mounted on the provided mobile terminal device with the B surface facing upward. That is, the battery pack 2 can be shared by a mobile terminal device in which the power supply terminal is provided on the left side in the longitudinal direction and a mobile terminal device in which the power supply terminal is provided on the right side in the longitudinal direction. .

  Therefore, for example, an existing battery pack for mounting on a mobile terminal device whose power supply terminal is provided on the left side in the longitudinal direction is replaced with a mobile terminal device on which the power supply terminal is provided on the right side in the longitudinal direction. Since it can be diverted, there is no need to newly design and produce a battery pack for mounting on a mobile terminal device having a power terminal provided on the right side in the longitudinal direction. Therefore, it is possible to reduce the cost, manpower, man-hours, time, etc. required for the new design of the battery pack.

  9A and 9B, the power supply terminals 4 are provided at positions corresponding to the positions of the power supply terminals 4 on the A and B surfaces of the battery pack 2. A display indicating the position where the power supply terminal is provided may be provided at a position corresponding to the position of the power supply terminal in each portable terminal device. When displayed in such a manner, it is possible to indicate to the user or the like the position where the power supply terminal is provided and the direction in which the battery pack 2 is mounted.

  In addition, the notch (groove 31) may not be formed in the claw portion provided in the battery pack 2. FIG. 10 is an explanatory view showing a battery pack provided with a claw portion 23 in which notches are not formed. In the example shown in FIG. 10, the claw portions 23 are provided at positions close to the left and right end portions in contact with the other side surfaces on the surface (first side surface) where the power supply terminal 4 of the battery pack 2 is provided. Yes. And the right nail | claw part 23 is provided in the position close | similar to the edge part which contact | connects the A surface in a 1st side surface, and the left claw part 23 contacts the edge part and B surface which contact | connect the A surface in a 1st side surface. It is provided near the center with the end.

  And based on the position of the power supply terminal provided in the portable terminal device, the battery pack is positioned at a position determined depending on whether the battery pack is mounted with the A side up or the B side up. Thus, a groove for accommodating the claw portions 23 is provided at a position facing each claw portion 23 when the battery pack is mounted.

  Note that the position where the right claw portion 23 and the left claw portion 23 are provided is not limited to the position shown in FIG. 10, and may be a position that is asymmetric with respect to the center point of the first side surface. That's fine.

  When such a claw portion 23 is provided in the battery pack and a groove is provided in a position corresponding to the claw portion 23 in the portable terminal device, the battery pack is portable with different positions of the power terminals. It can be attached to a terminal device. Therefore, the battery pack can be shared and used for portable terminal devices having different power terminal positions.

  In addition, since the right nail 23 and the left nail 23 are provided at positions that are asymmetric with respect to the center point of the first side surface, the battery pack is mounted on the portable terminal device with the front and back reversed. Even if it is going to do, since the nail | claw part 23 contacts the wall of the battery insertion part 14 provided in the portable terminal device, it can prevent that a battery pack fits in a portable terminal device.

  As shown in FIG. 10, a water wetness detection seal 20 that detects that the battery pack has been wetted may be attached. Further, as shown in FIG. 10, a hole may be formed inside the claw portion 23.

  In addition, although the mobile phone was illustrated as the portable terminal device 6 and the portable terminal device 16, the portable terminal device is a battery pack such as a PHS (Personal Handy-phone System) terminal, a PDA (Personal Digital Assistant), or a portable audio device.
