図１ないし図３を参照すると、本発明の一実施形態による自然放電防止用充電装置は、大別して、充電池１１４と、これを取り囲んでいる充電池筐体１１０、及び充電池筐体１１０の一方の側に備えられて充電池筐体１１０のプラス端子（（＋）端子）１１１及びマイナス端子（（−）端子）１１２を外部と隔離させるカバー１２０とで構成される。   Referring to FIGS. 1 to 3, the spontaneous discharge preventing charging apparatus according to an embodiment of the present invention is roughly divided into a rechargeable battery 114, a rechargeable battery casing 110 surrounding the rechargeable battery 114, and a rechargeable battery casing 110. The cover 120 is provided on one side and separates the positive terminal ((+) terminal) 111 and the negative terminal ((−) terminal) 112 of the rechargeable battery housing 110 from the outside.

これを詳述すると、充電池１１４としては、鉛蓄電池、ニッケル・カドミウム（ＮｉＣｄ）電池、ニッケル水素（ＮｉＭＨ）電池、リチウムイオン（Ｌｉ−ｉｏｎ）電池、リチウムイオンポリマー（Ｌｉ−ｉｏｎ ｐｏｌｙｍｅｒ）電池などのように一般に公知されている充電池を使用することができる。   More specifically, as the rechargeable battery 114, a lead storage battery, a nickel cadmium (NiCd) battery, a nickel metal hydride (NiMH) battery, a lithium ion (Li-ion) battery, a lithium ion polymer (Li-ion polymer) battery, or the like. A generally known rechargeable battery can be used.

充電池筐体１１０は、充電池１１４がその内部に収容できるように形成され、充電池１１４を保護し且つ充電池１１４を外部と隔離させる筐体である。充電池筐体１１０は、充電池１１４の陽極（（＋）極）及び陰極（（−）極）にそれぞれ接続される（＋）端子１１１及び（−）端子１１２を備え、充電池１１４の（＋）極と（−）極を外部と完全に隔離させることで自然放電を抑制する。参考として、図中では充電池１１４の（＋）極と（−）極とを明示的に示してはいないが、充電池１１４の（＋）極と（−）極とは製造時から充電池筐体１１０の（＋）端子１１１及び（−）端子１１２に接触するように形成されていてもよく、また、電線や導体などを介して充電池筐体１１０の（＋）端子１１１及び（−）端子１１２に接続されるように形成されていてもよい。言い換えれば、充電池筐体１１０は、充電装置の製造時に充電池１１４の（＋）極及び（−）極が充電池筐体１１０の（＋）端子１１１及び（−）端子１１２に直接接触するように充電池１１４と一体型で形成されていてもよく、また、充電池１１４の（＋）極及び（−）極を電線などを介して充電池筐体１１０の（＋）端子１１１及び（−）端子１１２に接続させた後、充電池筐体１１０に充電池１１４を組み込んで固定板１１３で封止する形態で形成されていてもよい。そして、その結果、充電池１１４の（＋）極及び（−）極が外部と完全に隔離されるようになる。   The rechargeable battery case 110 is a case that is formed so that the rechargeable battery 114 can be accommodated therein, protects the rechargeable battery 114, and isolates the rechargeable battery 114 from the outside. The rechargeable battery case 110 includes a (+) terminal 111 and a (−) terminal 112 connected to the anode ((+) electrode) and the cathode ((−) electrode) of the rechargeable battery 114, respectively. Spontaneous discharge is suppressed by completely separating the (+) and (-) poles from the outside. For reference, the (+) and (−) poles of the rechargeable battery 114 are not explicitly shown in the figure, but the (+) and (−) poles of the rechargeable battery 114 are rechargeable batteries from the time of manufacture. It may be formed so as to be in contact with the (+) terminal 111 and the (−) terminal 112 of the housing 110, and the (+) terminal 111 and the (−) of the rechargeable battery housing 110 via an electric wire or a conductor. ) It may be formed so as to be connected to the terminal 112. In other words, in the rechargeable battery case 110, the (+) and (−) poles of the rechargeable battery 114 are in direct contact with the (+) terminal 111 and the (−) terminal 112 of the rechargeable battery case 110 when the charging device is manufactured. The rechargeable battery 114 may be integrally formed, and the (+) and (−) poles of the rechargeable battery 114 are connected to the (+) terminals 111 and ( -) After connecting to the terminal 112, the rechargeable battery 114 may be incorporated in the rechargeable battery housing 110 and sealed with the fixing plate 113. As a result, the (+) electrode and the (−) electrode of the rechargeable battery 114 are completely isolated from the outside.

カバー１２０は、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２にそれぞれ対応するプラス端子（（＋）端子）１２１及びマイナス端子（（−）端子）１２２を備え、上記充電池筐体１１０の一方側に取り付けられて充電池筐体１１０の（＋）端子１１１及び（−）端子１１２を外部と隔離させる。参考として、カバー１２０の（＋）端子１２１及び（−）端子１２２は、充電時にはソーラセル（ｓｏｌａｒ ｃｅｌｌ）などに接続されて充電を遂行するようになり、電源供給の際は、電子機器などに接続されて電源供給を遂行するようになる。また、図中では示されていないが、カバー１２０の（＋）端子１２１及び（−）端子１２２を覆って外部と隔離させる端子蓋体（例えば、ねじ止め方式や嵌め込み方式にて取り付けられるゴム蓋体）を備えることもできる。   The cover 120 includes a plus terminal ((+) terminal) 121 and a minus terminal ((−) terminal) 122 corresponding to the (+) terminal 111 and the (−) terminal 112 of the rechargeable battery housing 110, respectively. The (+) terminal 111 and the (−) terminal 112 of the rechargeable battery case 110 are attached to one side of the case 110 to isolate them from the outside. For reference, the (+) terminal 121 and the (−) terminal 122 of the cover 120 are connected to a solar cell or the like when charging, and are connected to an electronic device or the like when supplying power. The power supply is performed. Further, although not shown in the drawing, a terminal lid body (for example, a rubber lid attached by a screwing method or a fitting method) that covers the (+) terminal 121 and the (−) terminal 122 of the cover 120 and isolates them from the outside. Body).

充電池筐体１１０とカバー１２０の取り付け形態は、例えば、充電池筐体１１０の外周面にねじ山が形成され、カバー１２０の内周面にそれに対応するねじ山が形成されることでねじ止め方式にて取り付けることができる。勿論、充電池筐体１１０とカバー１２０との取り付け形態は、ねじ止め方式の他、公知の様々な方式を用いればよい。   The attachment form of the rechargeable battery housing 110 and the cover 120 is, for example, a screw thread formed on the outer peripheral surface of the rechargeable battery housing 110 and a corresponding screw thread formed on the inner peripheral surface of the cover 120. It can be attached by the method. Of course, the attachment form of the rechargeable battery housing 110 and the cover 120 may use various known methods in addition to the screwing method.

図２及び図３を参照すると、図２は、カバー１２０が充電池筐体１１０に完全にねじ止めされ、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２がカバー１２０の（＋）端子１２１及び（−）端子１２２と接触した状態を示す図であり、図３は、カバー１２０が充電池筐体１１０に完全にねじ止めされておらず、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２がカバー１２０の（＋）端子１２１及び（−）端子１２２と接触していない状態を示す図である。   2 and 3, FIG. 2 shows that the cover 120 is completely screwed to the rechargeable battery case 110, and the (+) terminal 111 and the (−) terminal 112 of the rechargeable battery case 110 are FIG. 3 is a diagram illustrating a state in which the (+) terminal 121 and the (−) terminal 122 are in contact with each other. FIG. 3 illustrates that the cover 120 is not completely screwed to the rechargeable battery case 110. FIG. 4 is a diagram illustrating a state where the terminal 111 and the (−) terminal 112 are not in contact with the (+) terminal 121 and the (−) terminal 122 of the cover 120.

これを詳述すると、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２が外部と完全に隔離された状態における、図２の場合は、カバー１２０の（＋）端子１２１及び（−）端子１２２と接触し、その結果、充電や電源供給を遂行することができる場合であり、図３の場合は、カバー１２０の（＋）端子１２１及び（−）端子１２２と接触しておらず、その結果、充電や電源供給を遂行することができない場合である。すなわち、本発明による充電装置は、使用状態では充電池筐体１１０の（＋）端子１１１及び（−）端子１１２とカバー１２０の（＋）端子１２１及び（−）端子１２２とが接触し、充電池１１４から充電や電源供給を遂行するようになり、未使用状態では充電池筐体１１０の（＋）端子１１１及び（−）端子１１２とカバー１２０の（＋）端子１２１及び（−）端子１２２とが接触しておらず、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２を外部と隔離させることで自然放電が起こることを抑制する。参考として、この場合、カバー１２０の（＋）端子１２１及び（−）端子１２２は、ソーラセル、電子機器などとの接続が容易な大きさ及び形状で形成し、充電池筐体１１０の（＋）端子１１１及び（−）端子１１２は、表面積が小さく（例えば、カバー１２０の（＋）端子１２１及び（−）端子１２２よりも小さい表面積を有するように）形成することにより、自然放電の効率を高めることができる。   More specifically, in the case of FIG. 2 in a state where the (+) terminal 111 and the (−) terminal 112 of the rechargeable battery housing 110 are completely isolated from the outside, the (+) terminal 121 and ( −) Is in contact with the terminal 122, and as a result, charging and power supply can be performed. In the case of FIG. 3, it is not in contact with the (+) terminal 121 and the (−) terminal 122 of the cover 120. As a result, charging or power supply cannot be performed. That is, in the charging device according to the present invention, the (+) terminal 111 and the (−) terminal 112 of the rechargeable battery housing 110 and the (+) terminal 121 and the (−) terminal 122 of the cover 120 are in contact with each other when in use. The battery 114 performs charging and power supply, and when not in use, the (+) terminal 111 and (−) terminal 112 of the rechargeable battery housing 110 and the (+) terminal 121 and (−) terminal 122 of the cover 120.
