本考案は、コ−ドレス電話機や携帯電話機等の充電用バッテリーを内蔵した電 子機器からなる被充電物に対する充電用電源の接続装置に関する。 The present invention relates to a device for connecting a charging power source to an object to be charged, which is an electronic device including a charging battery such as a cordless phone or a mobile phone.
【０００２】[0002]
従来、例えば、コードレス電話機等の被充電物に対する充電用電源の接続装置 として、図６に示すように、商用電源に接続された充電台６０に突起状の電源端 子６１を突設し、電話機等の被充電物６２の下面に電源端子６１に対応する凹状 の接続端子６３を凹設し、被充電物６２を充電台６０上に載置することによって 、被充電物６２の凹状接続端子６３を充電台６０の突起状電源端子６１に係嵌さ せて電源を接続し、充電台６０から被充電物６２の充電用バッテリーに電力を供 給するようにしていた。 2. Description of the Related Art Conventionally, as a device for connecting a charging power source to an object to be charged such as a cordless telephone, as shown in FIG. 6, a projecting power source terminal 61 is provided on a charging stand 60 connected to a commercial power source so as to project the telephone. A concave connection terminal 63 corresponding to the power supply terminal 61 is provided on the lower surface of the object 62 to be charged, and the object 62 to be charged is placed on the charging base 60. The power supply is connected to the projecting power supply terminals 61 of the charging stand 60 by connecting the power supply to supply the electric power from the charging stand 60 to the charging battery of the article 62 to be charged.
【０００３】[0003]
このように、充電台から被充電物の充電用電源に有接点方式により、電力を供 給するのでは、長期間の頻繁な使用により接点部分に接触不良を起こし、充分に 電力を供給することができないという故障が発生していた。 In this way, when power is supplied from the charging stand to the power source for charging the object to be charged by the contact method, it is necessary to supply sufficient power because contact failure occurs at the contact part due to frequent use for a long period of time. There was a failure that could not be done.
【０００４】 また、充電台に水等の導電性の液体が触れると、充電器が破損したり、充電時 以外でも電力消費が多くなったり、あるいは被充電物の接続端子に同じように水 等の導電性の液体が付着すると、充電用バッテリーが自然消耗することになり、 耐湿性、防水性が悪く、高湿性や水分の多い場所での使用が困難であった。Further, when a conductive liquid such as water comes into contact with the charging stand, the charger may be damaged, power consumption may be increased even when the charging base is not charged, or water or the like may be similarly applied to a connection terminal of an object to be charged. If the electrically conductive liquid adheres to the battery, the charging battery will be consumed naturally, and the moisture resistance and waterproof properties are poor, making it difficult to use in locations with high humidity and high water content.
【０００５】 このように従来の充電器と被充電物との接続には多くの問題があった。As described above, there are many problems in the connection between the conventional charger and the object to be charged.
【０００６】 本考案は、これらの問題点を払拭することを解決しようとする課題とするもの である。The present invention aims to solve these problems by solving them.
【０００７】[0007]
本考案は上記課題を解決するために、実施例に示す参照符号を付して示せば、 請求項１にあっては、充電台１に絶縁カバー１１で被われた一次コイル部２を設 け、これに対応するコードレス電話機等の被充電物３に絶縁カバー９で被われた 二次コイル部４を設け、被充電物３を充電台１に載置することによって、両コイ ル部２，４が互いに近接して電磁誘導部５を形成し、該電磁誘導部５の電磁誘導 作用により、充電台１から被充電物３の充電用バッテリー６に電力を供給するよ うに設定し、上記充電台側の絶縁カバー１１における上記一次コイル部２に対応 する部位の外面に、導電性異物Ｍを側方へ自重で滑落させて排除する異物排除部 １１Ａ（１１Ｂ）（１１Ｃ）を設けた構成を採用するものである。 In order to solve the above-mentioned problems, the present invention provides the primary coil section 2 covered with an insulating cover 11 on the charging stand 1 according to the present invention by referring to the reference numerals shown in the embodiments. By providing the secondary coil section 4 covered with the insulating cover 9 on the article to be charged 3 such as a cordless telephone, and placing the article to be charged 3 on the charging stand 1, both coil sections 2, 4 are arranged close to each other to form an electromagnetic induction unit 5, and the electromagnetic induction action of the electromagnetic induction unit 5 is set so that power is supplied from the charging stand 1 to the charging battery 6 of the object to be charged 3, and the above charging is performed. A foreign matter removing section 11A (11B) (11C) is provided on the outer surface of the base side insulating cover 11 corresponding to the primary coil section 2 to remove the conductive foreign matter M by sliding it sideways by its own weight. To be adopted.
【０００８】 また、請求項２によれば、前記一次コイル部２と二次コイル部４とは互いに同 心円状に配置されてなる請求項１記載の構成を採用するものである。According to a second aspect of the invention, the configuration according to the first aspect is adopted in which the primary coil portion 2 and the secondary coil portion 4 are arranged concentrically with each other.
【０００９】 また、請求項３によれば、前記一次コイル部２と二次コイル部４とは同軸状に 配置されてなる請求項１記載の構成を採用するものである。According to a third aspect, the configuration according to the first aspect is adopted, in which the primary coil portion 2 and the secondary coil portion 4 are coaxially arranged.
【００１０】[0010]
請求項１によれば、被充電物３を充電台１に載置することによって、両コイル 部２，４が互いに近接して電磁誘導部５を形成して電磁誘導作用を生起し、これ により充電台１側に繋がれる商用電源からの電気が電磁誘導部５を電源接続部と して、被充電物３の充電用バッテリー６に電力を無接点方式で供給することがで きる。さらに、一次コイル部２および二次コイル部４がそれぞれ絶縁カバー１１ ，９で被われているので、液体の付着による漏電などが防止される。とくに、上 記充電台１側の一次コイル部２上にコインなどの導電性異物Ｍが放置されても、 異物排除部１１Ａ（１１Ｂ）（１１Ｃ）により導電性異物Ｍを側方へ排除できる ので、導電性異物Ｍが誘導電流で加熱されることはなくなり、したがって、この 異物Ｍに触って火傷する事故などが未然に防止される。 According to the first aspect, when the object to be charged 3 is placed on the charging stand 1, the coil portions 2 and 4 are close to each other to form the electromagnetic induction portion 5 and the electromagnetic induction action is generated. Electricity from a commercial power source connected to the charging stand 1 side can supply power to the charging battery 6 of the object to be charged 3 in a contactless manner by using the electromagnetic induction unit 5 as a power source connecting unit. Further, since the primary coil portion 2 and the secondary coil portion 4 are covered with the insulating covers 11 and 9, respectively, it is possible to prevent leakage of electricity due to liquid adhesion. In particular, even if a conductive foreign matter M such as a coin is left on the primary coil section 2 on the charging stand 1 side, the foreign matter removing section 11A (11B) (11C) can remove the conductive foreign matter M laterally. Therefore, the conductive foreign matter M is not heated by the induced current, so that accidents such as burns caused by touching the foreign matter M can be prevented.
【００１１】 また、請求項２によれば、前記一次コイル部２と二次コイル部４とは互いに同 心円状に配置されてなるため、充電台１に被充電物３を載置したときの全体の高 さを低く押さえることができる。Further, according to the second aspect, since the primary coil portion 2 and the secondary coil portion 4 are arranged concentrically with each other, when the object to be charged 3 is placed on the charging stand 1. The overall height of can be kept low.
【００１２】 更に請求項３によれば、前記一次コイル部２と二次コイル部４とは同軸状に配 置されてなるため、全体の幅寸法を小さくすることが可能となる。Further, according to the third aspect, since the primary coil portion 2 and the secondary coil portion 4 are coaxially arranged, it is possible to reduce the overall width dimension.
【００１３】[0013]
図１は、本考案の一実施例を示すもので、被充電物３としてコードレス電話機 や携帯電話機を示す。この電話機３は、電話機本体８と該本体８の底部に取り付 けた二次側機器ケース９とからなり、該機器ケース９内に後述の充電用部品がユ ニット状に配設されている。 FIG. 1 shows an embodiment of the present invention, and shows a cordless phone or a mobile phone as an object 3 to be charged. The telephone 3 is composed of a telephone body 8 and a secondary-side equipment case 9 attached to the bottom portion of the body 8, and the charging parts to be described later are arranged in a unit shape in the equipment case 9.
【００１４】 また、電話機３が載置される充電台１には、充電台本体１０と、この上部側に 取り付けられる一次側機器ケース１１とからなり、この機器ケース１１は樹脂材 料等の絶縁材によって形成され、絶縁カバーの役割も果たすようになっている。 この機器ケース１１の内部にはコイル枠１２の外周面に巻回された一次コイル部 ２とコイル枠１２の中心に配設されたコア１３とを有し、この一次コイル部２は 図示のように機器ケース１１と共に充電台本体１０の上面から突出状となって一 種の雄端子部１４を形成している。上記一次側機器ケース（絶縁カバー）１１に おける上記一次コイル部２に対応する部位は、コインや金属片のような導電性異 物Ｍ（図２）の停留を妨げて自重で側方へ滑落させる異物排除部１１Ａとして構 成されるように錐面１１ａをもった錐形に形成されている。Further, the charging stand 1 on which the telephone 3 is mounted is composed of a charging stand body 10 and a primary-side device case 11 attached to the upper side of the charging stand body 10. The device case 11 is insulated from resin material or the like. It is made of a material and acts as an insulating cover. Inside the equipment case 11, there are a primary coil portion 2 wound around the outer peripheral surface of a coil frame 12 and a core 13 arranged at the center of the coil frame 12, and the primary coil portion 2 is as shown in the drawing. In addition, a kind of male terminal portion 14 is formed so as to project from the upper surface of the charging stand body 10 together with the equipment case 11. A portion of the primary-side device case (insulating cover) 11 corresponding to the primary coil portion 2 prevents the conductive foreign object M (FIG. 2) such as a coin or a metal piece from stopping, and slides to the side by its own weight. It is formed in a cone shape having a conical surface 11a so as to be configured as the foreign matter removing portion 11A.
【００１５】 また、上記の二次側機器ケース９も樹脂材料等の絶縁材によって形成され、該 ケース９は絶縁カバーの役割も果たすようになっている。該ケース９の内部には 、コイル枠１５の外周面に二次コイル部４が巻回され、コイル枠１５の上面に各 種電気部品を取り付けるためのプリント基板１６が配設されると共に、該プリン ト基板１６に制御回路１７が接続され、該制御回路１７には、整流回路、タイマ ー、あるいは安定回路等周知の充電用回路が設けられている。この制御回路１７ は接点部材１８によって充電用バッテリー６に接続されると共に、図示しないが 電話機本体８の駆動用機器に電気的に接続されるようになっている。二次コイル 部４が設けられる部分は機器ケース９と共に、その中心部が上記一次側機器ケー ス１１における錐形の異物排除部１１Ａに対応して凹状に窪んだ一種の雌端子部 １９を形成するようになっている。なお、このように機器ケース９内に充電用部 品がユニット状に配設されていることによって、これらの部品を収納した機器ケ ース９を電話機本体８に装着するだけでよいから製造を効率的に行うことができ る。The secondary device case 9 is also formed of an insulating material such as a resin material, and the case 9 also functions as an insulating cover. Inside the case 9, the secondary coil portion 4 is wound around the outer peripheral surface of the coil frame 15, a printed circuit board 16 for mounting various kinds of electric components is provided on the upper surface of the coil frame 15, and A control circuit 17 is connected to the print substrate 16, and the control circuit 17 is provided with a known charging circuit such as a rectifying circuit, a timer, or a stabilizing circuit. The control circuit 17 is connected to the charging battery 6 by a contact member 18 and is electrically connected to a driving device of the telephone body 8 (not shown). The part where the secondary coil part 4 is provided is formed with a device case 9 and a kind of female terminal part 19 whose central part is recessed in a concave shape corresponding to the conical foreign substance removing part 11A in the primary side device case 11. It is supposed to do. Since the charging parts are arranged in a unit in the device case 9 as described above, the device case 9 accommodating these parts only needs to be mounted on the telephone body 8, so that the manufacturing is possible. It can be done efficiently.
【００１６】 そして、電話機３を充電台１に載置することによって、電話機３の雌端子部１ ９は若干圧嵌的に充電台１の雄端子部１４に係嵌して両端子部１９，１４は動揺 しないようになっていると共に、充電台１の一次コイル部２と電話機３の二次コ イル部４とが近接状態になり、これによって両コイル部２，４間に電磁誘導部５ が形成されるようになっている。Then, by placing the telephone 3 on the charging base 1, the female terminal portion 19 of the telephone 3 is slightly press-fitted to the male terminal portion 14 of the charging base 1 so that both terminal portions 19, 14 is designed not to sway, and the primary coil section 2 of the charging stand 1 and the secondary coil section 4 of the telephone 3 are brought into close proximity to each other, whereby the electromagnetic induction section 5 is placed between the coil sections 2 and 4. Are formed.
【００１７】 従って、充電台１側の一次コイル部２に供給される商用電源からの電気は電磁 誘導部５を介して電話機３の二次コイル部４に伝導され、制御回路１７を経て充 電用バッテリー６に電力が供給されることになる。すなわち、充電用バッテリー ６への電力供給を無接点方式で行えるので、長期間にわたって電気的接触不良が 発生するのが防止され、適正な電力供給機能が保たれる。さらに、一次コイル部 ２と二次コイル部４とは、それぞれ機器ケース１１，９でそれぞれ被われている ので、防湿、防水性が付与され、機器の電気系が腐食したり、漏電事故の発生な どを防止することができる。Therefore, electricity from the commercial power source supplied to the primary coil section 2 on the charging stand 1 side is conducted to the secondary coil section 4 of the telephone 3 through the electromagnetic induction section 5, and charged via the control circuit 17. Power will be supplied to the battery 6 for use. That is, since electric power can be supplied to the charging battery 6 by a non-contact method, electrical contact failure is prevented from occurring for a long period of time, and an appropriate electric power supply function is maintained. Furthermore, since the primary coil portion 2 and the secondary coil portion 4 are covered by the device cases 11 and 9, respectively, moisture-proof and waterproof properties are imparted, and the electrical system of the device is corroded or an electric leakage accident occurs. It is possible to prevent throat.
【００１８】 このように、一次コイル部２によって発生した磁束は二次コイル部４と鎖交し 、一次コイル部２と二次コイル部４との巻数比にほぼ比例した電圧を二次コイル 部４に発生するが、電話機３を充電台１から離すと、両コイル部２，４間に電磁 誘導部５がなくなるから、当然に二次コイル部４への電力の供給が停止される。As described above, the magnetic flux generated by the primary coil unit 2 interlinks with the secondary coil unit 4, and a voltage substantially proportional to the winding ratio of the primary coil unit 2 and the secondary coil unit 4 is applied to the secondary coil unit 4. However, when the telephone 3 is separated from the charging stand 1, the electromagnetic induction section 5 disappears between the coil sections 2 and 4, so that the power supply to the secondary coil section 4 is naturally stopped.
【００１９】 ところで、図２に示すように、上記一次側機器ケース１１における一次コイル 部２に対応する部位にコインのような導電性異物Ｍが放置されていたとすると、 一次コイル部２による誘導電流によって上記異物Ｍが加熱され、使用時などにこ れを触ってしまうと、火傷をする危険がある。この点について、上記の例では、 一次側機器ケース１１における一次コイル部２に対応する部位１１Ａを異物排除 部として錐形に形成してあるので、ここに放置されたコインなどの導電性異物Ｍ は図３のように錐面１１ａを滑落して側方へ排除されることになる。従って、導 電性異物Ｍが上記のように加熱されることはなく、安全に使用することができる 。By the way, as shown in FIG. 2, assuming that a conductive foreign matter M such as a coin is left at a site corresponding to the primary coil portion 2 in the primary side device case 11, an induced current by the primary coil portion 2 is generated. If the foreign matter M is heated by this and touches it during use, there is a risk of burns. With respect to this point, in the above example, the portion 11A corresponding to the primary coil portion 2 in the primary-side device case 11 is formed in a pyramidal shape as the foreign matter exclusion portion, so that the conductive foreign matter M such as a coin left here is left. Will be slid off the conical surface 11a as shown in FIG. Therefore, the conductive foreign matter M is not heated as described above and can be used safely.
【００２０】 なお、上記の例では、一次コイル部２と二次コイル部４とが互いに同心状に配 置されているので、充電台１に電話機３を載置した状態での全体の高さを低くす ることができる。また、上記異物排除部１１Ａが錐形であるので、雌端子部１９ と雄端子部１４の係嵌操作が錐面１１Ａでガイドされて容易になる。In the above example, since the primary coil portion 2 and the secondary coil portion 4 are arranged concentrically with each other, the overall height of the charging stand 1 with the telephone 3 placed thereon is reduced. Can be lowered. Further, since the foreign matter removing portion 11A has a conical shape, the engaging operation of the female terminal portion 19 and the male terminal portion 14 is facilitated by being guided by the conical surface 11A.
【００２１】 ところで、上記の例では、一次側機器ケース１１に形成される異物排除部を錐 形部１１Ａで構成したが、これに限定されるものではない。例えば、図４に示す ように片側斜面１１ｂを有する鋸歯形部１１Ｂで構成したり、あるいは図５に示 すように突起１１ｃで構成してもよい。いずれの場合でも、前記実施例と同様に コインなどの導電性異物Ｍの停留を妨げてこれを一次コイル部２上から側方へ排 除することができる。勿論、図４および図５に示すものにおいても、二次機器ケ ース９側に、鋸歯形部１１Ｂや突起１１ｃをそれぞれ嵌入させる凹状に窪んだ雌 端子１９Ｂ，１９Ｃが形成される。また、図４のように異物排除部１１Ａが片側 斜面１１ｂを有する形状であると、電話機３の装着に方向性を持たせる場合に利 用できることになる。By the way, in the above example, the foreign matter removing portion formed in the primary-side equipment case 11 is formed by the conical portion 11A, but the present invention is not limited to this. For example, as shown in FIG. 4, it may be constituted by a saw-toothed portion 11B having a sloping surface 11b on one side, or by a protrusion 11c as shown in FIG. In any case, as in the above-described embodiment, the retention of the conductive foreign matter M such as coins can be prevented and the foreign matter can be removed laterally from above the primary coil portion 2. Of course, also in the one shown in FIGS. 4 and 5, female terminals 19B, 19C recessed in a concave shape into which the saw-toothed portion 11B and the protrusion 11c are fitted are formed on the secondary device case 9 side. Further, as shown in FIG. 4, if the foreign matter removing portion 11A has a shape having a sloping surface 11b on one side, it can be used when the mounting of the telephone 3 is made directional.
【００２２】 なお、図１に示す実施例は、一次コイル部２と二次コイル部４とを同心円状に 配置したものであるが、図２に示す実施例は、一次コイル部２と二次コイル部４ とを同軸状に配置してなるものである。即ち、充電台１に一次コア２０に巻回さ れた一次コイル部２を設け、電話機３に二次コア２１に巻回された二次コイル部 ４を前記一次コイル部２と同軸状に設けてなるもので、この場合には、同心円状 に配置するものに比して全体の横幅寸法を小さくすることが可能となる。In the embodiment shown in FIG. 1, the primary coil portion 2 and the secondary coil portion 4 are arranged concentrically, but in the embodiment shown in FIG. 2, the primary coil portion 2 and the secondary coil portion 4 are arranged. The coil portion 4 is arranged coaxially. That is, the charging base 1 is provided with the primary coil portion 2 wound around the primary core 20, and the telephone 3 is provided with the secondary coil portion 4 wound around the secondary core 21 coaxially with the primary coil portion 2. In this case, it is possible to reduce the overall width dimension as compared with the case where they are arranged concentrically.
【００２３】 図１及び図４に示す実施例にあっては、機器ケース９内に二次コイル部４、プ リント基板１６、制御回路１７及び充電用バッテリー６をユニット状に収納して なるものであるが、図５に示すものは、上記部品のうち、充電用バッテリー６は 電話機本体８に直接に取り付けられ、二次コイル部４、プリント基板１６及び制 御回路１７のみを機器ケース９に収納したものである。このようにした場合、前 記突起１１ｃのような異物排除部を嵌入させるための雌端子部１９Ｃを、上記充 電用バッテリー６などの位置に制約されることなく、容易に形成することが可能 となる。In the embodiment shown in FIGS. 1 and 4, the secondary coil portion 4, the print substrate 16, the control circuit 17, and the charging battery 6 are unitarily housed in the equipment case 9. However, in the one shown in FIG. 5, among the above parts, the charging battery 6 is directly attached to the telephone body 8, and only the secondary coil portion 4, the printed circuit board 16 and the control circuit 17 are placed in the equipment case 9. It is stored. In this case, it is possible to easily form the female terminal portion 19C for inserting the foreign matter removing portion such as the protrusion 11c without being restricted to the position of the charging battery 6 or the like. Becomes
【００２４】 なお、前記各実施例では、異物排除部１１Ａ，１１Ｂ，１１Ｃを絶縁ケース１ １における一次コイル部２に対応する部位に一体形成したものであるが、上記部 位の外面に別部材で形成した異物排除部を設けることも可能である。In each of the above-mentioned embodiments, the foreign matter removing portions 11A, 11B and 11C are integrally formed in a portion of the insulating case 11 corresponding to the primary coil portion 2. However, a separate member is provided on the outer surface of the above-mentioned portion. It is also possible to provide the foreign matter removing portion formed in (4).
【００２５】[0025]
本考案の請求項１によれば、充電台からの電源を、電磁誘導部を介して無接触 に被充電物の充電用バッテリーに接続することができるから、従来のように有接 点による電源接続装置に比べて接触不良を起こすことが全くなく、それだけ長期 にわたって安定して使用することができ、さらに、充電台と被充電物との互いの 接続用端子部は導電性の端子が何ら露出することがないため、防湿、防水性に優 れており、高湿な場所での使用が可能になる。とくに、充電台側の絶縁ケースの 一次コイル部上に対応する部位の外面に設けた異物排除部により、コインのよう な導電性異物を側方へ排除できるので、導電性異物が誘導電流で加熱されること がなくなり、従って、この導電性異物に触って火傷するといった事故の恐れを解 消することができる。 According to claim 1 of the present invention, the power source from the charging stand can be contactlessly connected to the battery for charging the object to be charged through the electromagnetic induction portion, so that the conventional power source using a tangential point is used. Compared to the connection device, it does not cause contact failure at all, and it can be used stably for a long period of time.Furthermore, the conductive parts are not exposed at the connection terminal part of the charging stand and the object to be charged. Since it does not occur, it is excellent in moisture resistance and waterproofness, and it can be used in high humidity places.
