Description

本発明は、携帯電話に内蔵された電池が消耗して通信・通話不能になった際に、携帯電話の端子に接続することにより通信・通話できる携帯電話用電源機器に関する。   The present invention relates to a mobile phone power supply device that can communicate and talk by connecting to a terminal of a cellular phone when a battery built in the cellular phone is exhausted and communication / call is impossible.

I may feel it. In such a case, a mobile phone power supply device is commercially available as an external power source that can communicate and talk by connecting to the terminal of the mobile phone.

従来の携帯電話用電源機器は、機器本体に携帯電話の端子に接続される接続端子を有すると共に内部にＤＣ−ＤＣ昇圧回路が設けられている。また、機器本体には市販の単３や単４の円筒型乾電池を複数本収納する電池ボックスが設けられ、電池ボックスには円筒型乾電池の一端部の陰極電極と接触する接触端子と、円筒型乾電池の他端部の陽極電極と接触する接触端子が設けられている。そして、電池ボックスに円筒型乾電池を装着することにより、両電極が接触端子と接触してＤＣ−ＤＣ昇圧回路を介して接続端子に電気的に導通されるようになっている。
しかし、電池ボックスに設けられる接触端子は、円筒型乾電池の両電極と確実に接触させるためにばね性を持たせる必要があり、ばねの撓み分を考慮して所定のスペースを設ける必要があり、機器本体が大型となると共に、構造的に複雑となる。
そこで、前述のような問題を解決するために、円筒型乾電池の外周面の絶縁層を剥離し、陽極電極としての円筒部を露出し、露出した円筒部に電極端子を接触させ、電池室のスペースを軽減させた乾電池ボックスが知られている（例えば、特許文献１参照。）。

Is provided. This cylindrical dry battery 16 is a commercially available, for example, AA or AAA dry battery, and has an anode electrode 18 formed of a convex portion on one end face in the axial direction and a cathode electrode 19 on the other end face. Further, the outer peripheral surface of the cylindrical dry battery 16 is formed in a conductive layer (anode electrode 18) integral with the anode electrode 18, and the exterior of this conductive layer (anode electrode 18) is covered with an insulating film 20.
As shown in FIGS. 3 to 7, the dry cell mounting portion 17 has a cylindrical portion 21 made of an electrically insulating material so as to be fitted to an end portion on one end side of the cylindrical dry cell 16. A first contact terminal 22 connected to the cathode electrode 19 in a conductive state is provided at the inner bottom of the first contact terminal 22.

次に、携帯電話用電源機器の作用について説明する。
通常は、機器本体１１の乾電池装着部１７には円筒型乾電池１６が装着されていない。従って、円筒型乾電池１６の体積及び重量は含まないため、小型軽量で、携帯に便利であり、携帯電話のストラップに吊下げて携帯することも可能である。 Next, the operation of the mobile phone power supply device will be described.
Normally, the cylindrical battery 16 is not attached to the dry battery attachment portion 17 of the device body 11. Accordingly, since the volume and weight of the cylindrical dry battery 16 are not included, the cylindrical dry battery 16 is small and light, convenient for carrying, and can be carried by being suspended from a strap of a mobile phone.

携帯電話に内蔵された電池が消耗して通信・通話不能になった際には、携帯電話の端子に機器本体１１の接続端子１４を接続し、携帯電話用電源機器を外部電源として使用できる。このとき、まず、２本の円筒型乾電池１６の一端部（陰極電極１９側）を挿入ガイド２６の内面をガイドとしてそれぞれ乾電池装着部１７に挿入すると、陰極電極１９が第１の接触端子２２に接触して導通状態となり、第２の接触端子２９が円筒型乾電池１６の外周面に対向する。しかし、円筒型乾電池１６の外周面は絶縁膜２０によって覆われているため、第２の接触端子２９は陽極電極１８と非接触状態にある。
次に、操作摘み３２に手指を掛け、締付けリング３０をテーパ筒部２７の先端側、つまり、複数枚の把持片２５の先端側へ移動させると、各把持片２５はその付勢力に抗して狭窄され、歯２８が円筒型乾電池１６の外周面側に押付けられる。この状態で、円筒型乾電池１６を手指で摘み、その周方向に回すと、歯２８が円筒型乾電池１６の外周面を摺擦し、絶縁膜２０は歯２８によって剥離され、複数枚の把持片２５からなる第２の接触端子２９は円筒型乾電池１６の外周面の陽極電極１８と接触して電気的に導通状態となる。
従って、円筒型乾電池１６の陰極電極１９は第１の接触端子２２と接触し、陽極電極１８は第２の接触端子２９と接触し、円筒型乾電池１６はＤＣ−ＤＣ昇圧回路１３を介して接続端子１４と電気的に導通状態となり、接続端子１４を携帯電話の端子に接続することにより、携帯電話用電源機器を外部電源として使用できる。
このように、本発明の携帯電話用電源機器は、携帯電話の外部電源として使用するときに、機器本体１１に円筒型乾電池１６を装着すればよく、通常携帯の際には機器本体１１のみを携帯すればよく、小型・軽量で持ち運びしやすいという利点がある。
なお、前記実施形態においては、単３、単４の乾電池について説明したが、市販されている単１〜単６の乾電池においても適用できる。また、乾電池の接続は、直列、並列のいずれでもよい。さらに、ＤＣ−ＤＣ昇圧回路を内蔵したが、乾電池によってはＤＣ−ＤＣ降圧回路を内蔵よく、またはこれらを介さないで直接電池電圧を出力してもよい。
なお、この発明は、前記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、前記実施形態に開示されている複数の構成要素の適宜な組合せにより種々の発明を形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。さらに、異なる実施形態に亘る構成要素を適宜組合わせてもよい。 When the battery built in the mobile phone is exhausted and communication / call is disabled, the connection terminal 14 of the device body 11 is connected to the terminal of the mobile phone, and the power supply device for the mobile phone can be used as an external power source. At this time, when one end portion (cathode electrode 19 side) of the two cylindrical dry batteries 16 is first inserted into the dry battery mounting portion 17 using the inner surface of the insertion guide 26 as a guide, the cathode electrode 19 is connected to the first contact terminal 22. The second contact terminal 29 is in contact with the outer peripheral surface of the cylindrical battery 16. However, since the outer peripheral surface of the cylindrical dry battery 16 is covered with the insulating film 20, the second contact terminal 29 is not in contact with the anode electrode 18.
Next, when a finger is put on the operation knob 32 and the fastening ring 30 is moved to the distal end side of the tapered cylindrical portion 27, that is, the distal end side of the plurality of gripping pieces 25, each gripping piece 25 resists the urging force. The teeth 28 are pressed against the outer peripheral surface side of the cylindrical dry battery 16. In this state, when the cylindrical dry battery 16 is picked with fingers and rotated in the circumferential direction, the teeth 28 rub against the outer peripheral surface of the cylindrical dry battery 16, the insulating film 20 is peeled off by the teeth 28, and a plurality of gripping pieces are obtained. The second contact terminal 29 made of 25 comes into contact with the anode electrode 18 on the outer peripheral surface of the cylindrical dry battery 16 and becomes electrically conductive.
Therefore, the cathode electrode 19 of the cylindrical dry battery 16 is in contact with the first contact terminal 22, the anode electrode 18 is in contact with the second contact terminal 29, and the cylindrical dry battery 16 is connected via the DC-DC booster circuit 13. The mobile phone power supply device can be used as an external power source by being electrically connected to the terminal 14 and connecting the connection terminal 14 to the mobile phone terminal.
As described above, the power supply device for a mobile phone of the present invention is only required to attach the cylindrical dry battery 16 to the device main body 11 when used as an external power source of the mobile phone. It is only necessary to carry it, and there is an advantage that it is small, light and easy to carry.
In addition, although the said embodiment demonstrated the AA and AAA dry batteries, it is applicable also to the commercially available single 1 to AAA batteries. Further, the connection of the dry batteries may be either in series or in parallel. Further, although a DC-DC booster circuit is built in, a DC-DC step-down circuit may be built in depending on the dry battery, or the battery voltage may be output directly without going through these.
Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
