BEST MODE FOR CARRYING OUT THE INVENTION Next, preferred embodiments of the present invention used in a mobile phone will be described in detail with reference to the drawings.
Reference numeral 1 denotes a band member, and the band member 1 is a hand strap band or a neck strap band by previously forming a loop shape or a linear shape into a loop shape. The linear band member 1 is folded in two, and a loop is formed by bundling the floating end of the folded band member 1 with a hook-and-loop fastener or the like as the engaging means 2 attached to the band member 1. It will be a hanging band. The external power supply connecting portion 3 is provided at one end of the loop-shaped or linear band member 1, and the output connecting portion 4 is provided at the other end of the band member 1, and the output connecting portion 4 is provided. A connector member 4b for making an electrical connection with an input connection portion of a mobile electronic device (mobile phone) and a connecting member 4a that is locked and unlocked by a hanging member 8 of the mobile electronic device (mobile phone) are provided. .

The external power source connecting portion 3 and the output connecting portion 4 of the band member 1 are electrically connected by a covered stranded wire or the like which is hard to cut. Further, a lock mechanism 5 is provided on the connector member 4b of the output connection unit 4, and the lock mechanism 5 allows the connector member 4b to be unlocked and locked with the input connection unit of the portable electronic device (mobile phone). This ensures stable electrical connection and stable power supply.

In addition, the external power supply connection portion 3 is provided with an AC power supply insertion plug 3a in which the plug can be raised and lowered. In addition, the external power supply connection section 3 incorporates an AC / DC converting means 6 for converting an AC power source into a direct current and an electronic circuit such as a voltage converting means 7 for adjusting a direct current voltage to a working voltage of a portable electronic device (mobile phone). However, it is not always necessary to incorporate it in the external power source connecting portion 3, and the point is that the AC / DC is provided in the band member 1 between the external power source connecting portion 3 and the output connecting portion 4.
The conversion means 6 and the voltage conversion means 7 may be incorporated, and by dispersing each means in this way, the device can be made compact.

The hanging member 8 is connected to a connecting means J such as a hook which is connected to a strap mounting hole S of a portable electronic device (mobile phone) through a rectangular ring portion 20 at one end, and a connecting portion at the other end. The portable electronic device (mobile phone) is hung and connected to the band member 1 by connecting the connecting member 8a to the connecting member 4a of the band member 1. The connecting portion 8
A protective cover 4c for preventing the connector member 4b of the connecting member 4a from being soiled is provided inside a. When the connecting member 4a and the connecting portion 8a are in a connected state, the tip of the connector member 4b is fitted to the protective cover 4c. It is supposed to be done.

Further, the unlocking operation of the lock mechanism 5 of the connector member 4b is performed by pressing the elastic insertion plug portions 12, 12 with the locking claws 12a of the connecting member 4a from both sides to push the button of the lock mechanism 5. Is done. The retaining connection between the connecting member 4a and the connecting portion 8a of the hanging member 8 is
Elastic insertion plug part 1 with engaging claw 12a of connecting member 4a
2, 12 and the locking socket portions 13, 13 of the connecting portion 8a into which the elastic plug portions 12, 12 are inserted. Since the tips of the elastic insertion plug portions 12 and 12 are tapered, when the elastic insertion plug portions 12 and 12 are fitted into the locking socket portion 13, the tapered tapered portions at the tips are locked. It is inserted into the hole opening edge of the socket portion 13. Then, by being forcibly inserted, the tapered taper portion is elastically bent inward and inserted into the locking socket portion 13. Then, when the tapered taper portion penetrates the locking socket portions 13 and 13 and comes out, the tapered taper portion of the elastic insertion plug portions 12 and 12 elastically returns to the old shape, and the elastic insertion plug portions 12 and 12 are returned. The locking claw 12a is locked to the edge of the outlet side hole of the locking socket 13 and is pulled out.

In the thus constructed device, the hanging member 8 is first attached to the portable electronic device (mobile phone).
For this attachment, a connecting means J such as a hook that is associated with the strap attachment hole S of the portable electronic device (mobile phone) is engaged with the rectangular ring portion 20 of the suspension member 8.

Next, after folding the band member 1 in two,
By banding the free side of the band member 1 with the hook-and-loop fastener as the engaging means 2, the band member 1 becomes a loop-shaped hanging band or a neck hanging band. Subsequently, the elastic insertion plug portions 12, 12 of the connecting member 4a are hung on the suspending member 8
The connecting member 4a and the connecting portion 8a are engaged and connected by being inserted into the locking socket portions 13 of the connecting portion 8a. Since the band member 1 and the hanging member 8 are connected by this engagement connection, the portable electronic device (mobile phone) is dropped or lost by hanging the handheld band on the hand or hanging the neckband on the neck. You can carry it with you.

When the rechargeable battery is exhausted due to the use of the portable electronic device (mobile phone), the connector member 4b of the output connecting portion 4 is used as it is in the case of the loop-shaped band member 1 in advance. (Cellular phone) and connect it by inserting it into the input connection section provided on the bottom. When the engaging means 2 is formed into a loop shape, the engaging means 2 is removed and the band member 1 that is folded in two and bundled is linearly extended, and then the connector member 4 of the output connection portion 4 is formed.
b is inserted into the input connector provided on the bottom of the portable electronic device (mobile phone) to be connected. Next, if the external power supply connection unit 3 is connected to the AC outlet in the room, the rechargeable battery will be charged. In addition, when going out or going out, it is sufficient to connect a battery power supply plug made of an AA battery (not shown) to the external power supply connection portion 3 of the band member 1 to supplement the power. Further, before going to bed, etc., the external power supply connecting portion 3 of the band member 1 is connected to an AC outlet to charge the rechargeable battery.

Then, the connector member 4 of the output connecting portion 4
When a is connected to an AC outlet, the AC / DC converting means 6 provided in the band member 1 converts the alternating current into the direct current, and the voltage converting means 7 changes the voltage according to the working voltage of the portable electronic device (mobile phone). Is converted and the rechargeable battery is charged. When charging is complete,
In the case of the loop-shaped band member 1, it is used as it is as a neck hanging band or a hand hanging band, and in the case of a linear band member 1, the band member 1 is looped by the engaging member 2 and used as a neck hanging band or a hand hanging band. You can do it.

In the preferred embodiment, the connecting member 4a is connected to the connecting portion 8a of the hanging member 8 so that the hanging member 8 can be carried while hanging and the connector member 4b of the connecting member 4a can be charged.
Is to be connected to the portable electronic device (mobile phone) by replacing the input connection part for charging, but the connecting member 4a and the connector member 4b are connected to the input connection part of the portable electronic device (mobile phone). The portable electronic device (mobile phone) needs to be newly designed in accordance with the connecting member 4a.
