Yes. (See Patent Document 1)

この公報に記載される充電器は、図１と図２に示すように、携帯機器９０を嵌合して装着する装着部８２を有するケース８１と、この装着部８２にセットされる携帯機器９０の電源端子９１に接触される出力端子部８３ａを有する充電接点８３と、装着部８２に携帯機器９０が装着されたことを検知して充電接点８３の出力端子部８３ａを装着部８２に突出させて、電源端子９１に接触させる傾動台８４とを備えている。   As shown in FIGS. 1 and 2, the charger described in this publication includes a case 81 having a mounting portion 82 for fitting and mounting a portable device 90, and a portable device 90 set in the mounting portion 82. The charging contact 83 having the output terminal portion 83a that is in contact with the power supply terminal 91 and the mounting portion 82 is detected to detect that the portable device 90 is mounted, and the output terminal portion 83a of the charging contact 83 is projected to the mounting portion 82. And a tilting base 84 to be brought into contact with the power supply terminal 91.

特開２００８−１１８７９８号公報JP 2008-118798 A

この充電器は、携帯機器を装着しない状態では、出力端子部をケース内に収納するので、正負の出力端子部に金属等の異物が接触してショートして、大きなショート電流が流れたり、濡れた手で接触して感電したり、低温やけどを被るのを有効に防止できる。ただ、この充電器は、薄い携帯機器の電源端子に、好ましい状態で充電接点の出力端子部を接触できない問題点がある。それは、山形に折曲している出力端子部をより小さく折曲加工するのが難しいからである。とくに、近年の携帯電話等の携帯機器は薄型化が要求されており、携帯機器の薄型化に伴って、これらの携帯機器の側面に設けられる電源端子も小さくすることが要求されている。このように、小さな電源端子に接触して電力を供給する充電接点は、出力端子部を小さくする必要がある。   This charger stores the output terminal part in the case when the mobile device is not attached. Therefore, a foreign object such as a metal contacts the positive and negative output terminal part and shorts, causing a large short current to flow or wet. You can effectively prevent contact with your hands and electric shocks and low temperature burns. However, this charger has a problem that the output terminal portion of the charging contact cannot be brought into contact with the power terminal of the thin portable device in a preferable state. This is because it is difficult to bend the output terminal portion bent in a mountain shape smaller. In particular, mobile devices such as mobile phones in recent years are required to be thin, and with the reduction in thickness of mobile devices, it is also required to reduce the power supply terminals provided on the side surfaces of these mobile devices. Thus, the charging contact that contacts the small power supply terminal and supplies power needs to make the output terminal portion small.

図３と図４は、断面形状を円形とする弾性金属線８０を折曲してなる山形の出力端子部８３ａを示している。このように、弾性金属線８０を折曲加工してなる充電接点８３は、より小さな曲率半径で折曲して出力端子部８３ａの接触部分を小さくできる。ただ、金属線を小さな曲率半径で折曲するには、種々の制約を受ける。例えば、図３の鎖線で示すように、太い金属線を小さな曲率半径で折曲してＵ曲すると、Ｕ曲部の内側では圧縮されて、外側は伸ばされて歪みが生じる。この歪みが大きくなると、破断してこの破断部分において金属線が切断されることがある。この問題は、金属線を細くすることで解決できる。細い金属線は、小さな曲率半径で折曲してＵ曲できるからである。ただ、細い金属線は、強度が弱くなるため、充電接点が変形しやすくなる。困ったことに、充電接点が変形すると、小さな電源端子の正確な位置に正しく接触させるのが難しくなって、接触不良の原因となり、場合によっては、携帯機器を充電できなくなる。また、細い金属線は電気抵抗も大きくなることから、充電時における電力損失も大きくなる。   3 and 4 show a mountain-shaped output terminal portion 83a formed by bending an elastic metal wire 80 having a circular cross-sectional shape. Thus, the charging contact 83 formed by bending the elastic metal wire 80 can be bent with a smaller radius of curvature to reduce the contact portion of the output terminal portion 83a. However, bending metal wires with a small radius of curvature is subject to various restrictions. For example, as shown by a chain line in FIG. 3, when a thick metal wire is bent with a small radius of curvature and U-curved, the inside of the U-curved portion is compressed and the outside is stretched to cause distortion. When this strain becomes large, the metal wire may be cut at the broken portion. This problem can be solved by making the metal wire thinner. This is because a thin metal wire can be bent and bent with a small radius of curvature. However, since the strength of the thin metal wire is weakened, the charging contact is easily deformed. Unfortunately, when the charging contact is deformed, it is difficult to contact the correct position of the small power terminal correctly, causing contact failure, and in some cases, the portable device cannot be charged. In addition, since a thin metal wire has an increased electrical resistance, power loss during charging also increases.

一般に、金属線を破断させることなく折曲するための曲率半径は、金属線の直径（Ｄ）に比例する。このため、太い金属線は、曲率半径を大きくする必要があり、出力端子部の先端部を小さく成形することができない。すなわち、金属線を太くすると、充電接点の強度を強くできるが、出力端子部を小さな曲率半径で折曲できなくなって、小さな電源端子に確実に接触できなくなり、反対に、金属線の太さを細くすると、出力端子部を小さな曲率半径で折曲して、小さな電源端子に接触させることができるが、充電接点の強度が弱くなって変形しやすくなる。これらは互いに相反する特性であって、両方を同時に満足することはできなかった。   In general, the radius of curvature for bending a metal wire without breaking it is proportional to the diameter (D) of the metal wire. For this reason, the thick metal wire needs to have a large radius of curvature, and the tip end portion of the output terminal portion cannot be formed small. In other words, if the metal wire is thickened, the strength of the charging contact can be increased, but the output terminal part cannot be bent with a small radius of curvature, making it impossible to reliably contact the small power supply terminal. If it is made thin, the output terminal portion can be bent with a small radius of curvature and brought into contact with a small power supply terminal, but the strength of the charging contact is weakened and is easily deformed. These were mutually contradictory properties, and both could not be satisfied at the same time.

本発明は、以上の欠点を解決することを目的に開発されたものである。本発明の重要な目的は、充電接点の強度を低下させることなく、金属線を小さな曲率半径で折曲して出力端子部の先端部分を小さくして、小さい電源端子に確実に接触させて充電できる充電器を提供することにある。   The present invention has been developed for the purpose of solving the above drawbacks. An important object of the present invention is to charge a metal wire by bending the metal wire with a small radius of curvature to reduce the tip of the output terminal portion and making sure that the small power terminal is in contact without reducing the strength of the charging contact. The object is to provide a charger that can.

課題を解決するための手段及び発明の効果Means for Solving the Problems and Effects of the Invention

本発明の充電器は、充電できる電池を内蔵する携帯機器５０を脱着自在に装着する装着部２を有するケース１と、このケース１に配設されて、装着部２にセットされる携帯機器５０の電源端子５１に接触される出力端子部３０を有する充電接点３とを備えている。充電接点３は、導電性と弾性を有する金属線８を折曲加工して成形している。出力端子部３０は、金属線８を所定の曲率半径でＵ曲してなるＵ曲部３０Ａを有し、このＵ曲部３０Ａの厚さ（ｄ１）を横幅（ｄ２）よりも小さくして横断面形状を非円形としている。
ただし、本明細書において、Ｕ曲部における厚さ（ｄ１）とは、金属線の曲げ方向の外径を意味し、横幅（ｄ２）とは、曲げ方向と垂直な幅方向の外径を意味するものとする。 The charger of the present invention includes a case 1 having a mounting portion 2 for detachably mounting a portable device 50 containing a rechargeable battery, and a portable device 50 disposed in the case 1 and set in the mounting portion 2. And a charging contact 3 having an output terminal portion 30 that is in contact with the power source terminal 51 of the battery. The charging contact 3 is formed by bending a metal wire 8 having conductivity and elasticity. The output terminal portion 30 has a U-curved portion 30A formed by bending the metal wire 8 with a predetermined radius of curvature, and the U-curved portion 30A has a thickness (d1) smaller than a lateral width (d2) and traverses. The surface shape is non-circular.

本発明の充電器は、充電接点の強度を低下させることなく、金属線を小さな曲率半径で折曲して出力端子部の先端部分を小さくできる特長がある。それは、金属線を折曲加工してなる充電接点の出力端子部が、金属線を所定の曲率半径でＵ曲してなるＵ曲部を有しており、このＵ曲部の厚さ（ｄ１）を横幅（ｄ２）よりも小さくして横断面形状を非円形としているからである。この充電接点は、金属線全体を細くするのではなく、Ｕ曲部の厚さ（ｄ１）を横幅（ｄ２）よりも小さくすることで、金属線をより小さな曲率半径で折曲してＵ曲部を設けるので、充電接点の強度を低下させることなく、金属線を小さな曲率半径で折曲して出力端子部を小型化できる。このように、出力端子部を小型化できる充電接点は、携帯機器の小さな電源端子にも確実に接触させて電力供給できる。   The charger of the present invention has a feature that the tip portion of the output terminal portion can be made small by bending the metal wire with a small curvature radius without reducing the strength of the charging contact. That is, the output terminal portion of the charging contact formed by bending a metal wire has a U-curved portion obtained by U-curving the metal wire with a predetermined radius of curvature, and the thickness (d1) of this U-curved portion. ) Is made smaller than the lateral width (d2), and the cross-sectional shape is non-circular. This charging contact does not make the entire metal wire thin, but by making the thickness (d1) of the U-curved portion smaller than the horizontal width (d2), the metal wire is bent with a smaller radius of curvature to form a U-curve. Since the portion is provided, the output terminal portion can be miniaturized by bending the metal wire with a small radius of curvature without reducing the strength of the charging contact. In this way, the charging contact that can reduce the size of the output terminal portion can reliably supply power to the small power supply terminal of the portable device.

The two terminal windows 13 project the positive and negative output terminal portions 30 to the mounting portion 2. In addition, the two through holes 15 project the pair of projecting portions 6 </ b> A provided in the detection body 6 to the mounting portion 2.

さらに、ケース１は、図１１に示すように、充電接点３を凸条１０Ａの収納部１１に配設するために、連結ロッド１６を一体的に成形して設けている。図の充電器は、第１ケース１Ａに一体的に成形して一対の連結ロッド１６を設けている。連結ロッド１６は、装着部２の底面２Ａと直交する方向に伸びるロッド状であって、充電接点３のコイル部３３に挿入できる外形に成形している。一対の連結ロッド１６に挿入してケース１に連結される一対の充電接点３は、凸条１０Ａの収納部１１に配設されて、第１アーム３１を装着部２の底面２Ａと平行な面内で回動させて、出力端子部３０を装着部２に突出させる。一対の連結ロッド１６は、一対の充電接点３の出力端子部３０が互いに接近する姿勢であって、一対の出力端子部３０を所定の間隔離して線対称に配置するように、ケース１に一体的に成形して設けられる。したがって、一対の連結ロッド１６の間隔は、一対の第１アーム３１の全長と一対の出力端子部３０の間隔との和に等しい間隔とされる。充電接点３は、コイル部３３に連結ロッド１６を挿入して、凸条１０Ａの収納部１１に配設される。したがって、連結ロッド１６は、充電接点３を凸条１０Ａの収納部１１に配設できる位置に設けられる。   Furthermore, as shown in FIG. 11, the case 1 is provided with a connecting rod 16 that is integrally molded in order to dispose the charging contact 3 in the storage portion 11 of the ridge 10 </ b> A.

さらに、図８ないし図１１に示すケース１は、往復運動体５と検出体６を所定の位置で往復運動できるように支持するガイドリブ１７、１８を内面に突出するように一体的に成形して設けている。   Further, the case 1 shown in FIGS. 8 to 11 is formed by integrally forming guide ribs 17 and 18 that support the reciprocating body 5 and the detecting body 6 so as to reciprocate at a predetermined position so as to protrude from the inner surface. Provided.

充電接点３は、導電性と弾性のある金属線を折曲加工して所定の形状に成形している。この金属線として、ばね用リン青銅の線材等の弾性金属線の表面を金メッキしたものが最適である。携帯機器５０の電源端子５１に対する接触不良を少なくできるからである。充電接点３は、一方の端部を折曲加工して出力端子部３０を設けている。この出力端子部３０を携帯機器５０の正負の電源端子５１に接触させて、携帯機器５０に内蔵される電池を充電する。したがって、充電接点３は、正負の出力端子部３０を互いに絶縁して電源端子５１に接触させるために、２本の充電接点３を互いに離して、収納部１１に配置している。一対の充電接点３は、出力端子部３０を電源端子５１に対して弾性的に押圧できるように収納部１１に配置している。図１１ないし図１３に示す充電接点３は、金属線の中間部をコイル状に巻いてコイル部３３とし、このコイル部３３から第１アーム３１と第２アーム３２とを外側に伸びる形状としている。第１アーム３１の端部に出力端子部３０を設けて、第２アーム３２をケース１に連結している。   The charging contact 3 is formed by bending a conductive and elastic metal wire into a predetermined shape. As this metal wire, the one in which the surface of an elastic metal wire such as a phosphor bronze wire for spring is plated with gold is optimal. This is because poor contact with the power supply terminal 51 of the portable device 50 can be reduced. The charging contact 3 is provided with an output terminal 30 by bending one end. The output terminal unit 30 is brought into contact with the positive and negative power supply terminals 51 of the portable device 50 to charge a battery built in the portable device 50. Therefore, the charging contacts 3 are arranged in the storage portion 11 so that the two charging contacts 3 are separated from each other in order to insulate the positive and negative output terminal portions 30 from each other and contact the power supply terminals 51. The pair of charging contacts 3 are arranged in the storage portion 11 so that the output terminal portion 30 can be elastically pressed against the power supply terminal 51. The charging contact 3 shown in FIG. 11 to FIG. 13 has a shape in which an intermediate portion of a metal wire is wound in a coil shape to form a coil portion 33, and the first arm 31 and the second arm 32 extend outward from the coil portion 33. . An output terminal 30 is provided at the end of the first arm 31, and the second arm 32 is connected to the case 1.

出力端子部３０は、金属線を所定の曲率半径でＵ曲してなるＵ曲部３０Ａを有し、このＵ曲部３０Ａを凸条１０Ａの端子窓１３から装着部２に突出させて、携帯機器５０の電源端子５１に接触させている。充電接点３は、図１４ないし図１９に示すように、金属線８を小さな曲率半径でＵ曲してＵ曲部３０Ａとするために、Ｕ曲部３０Ａの厚さ（ｄ１）を横幅（ｄ２）よりも小さくして横断面形状を非円形としている。ここで、Ｕ曲部３０Ａの厚さ（ｄ１）とは、金属線８の曲げ方向の外径であって、横断面形状を非円形とするＵ曲部３０Ａの短径を意味している。また、Ｕ曲部３０Ａの横幅（ｄ２）とは、金属線８の曲げ方向と垂直な幅方向の外径であって、横断面形状を非円形とするＵ曲部３０Ａの長径を意味している。   The output terminal portion 30 has a U-curved portion 30A formed by bending a metal wire with a predetermined radius of curvature, and the U-curved portion 30A protrudes from the terminal window 13 of the ridge 10A to the mounting portion 2 so as to be portable. The power supply terminal 51 of the device 50 is in contact. As shown in FIGS. 14 to 19, the charging contact 3 has a U-curved portion 30A having a thickness (d1) of a lateral width (d2) in order to form a U-curved portion 30A by bending the metal wire 8 with a small curvature radius. ) And the cross-sectional shape is non-circular. Here, the thickness (d1) of the U-curved portion 30A is the outer diameter in the bending direction of the metal wire 8, and means the short diameter of the U-curved portion 30A having a non-circular cross-sectional shape. Further, the lateral width (d2) of the U-curved portion 30A is the outer diameter in the width direction perpendicular to the bending direction of the metal wire 8, and means the long diameter of the U-curved portion 30A having a non-circular cross-sectional shape. Yes.

図１４と図１５に示す出力端子部３０は、金属線８を部分的に押し潰してＵ曲部３０Ａの横断面形状を非円形としている。図１５に示すＵ曲部３０Ａは、横断面形状を長円形として、厚さ（ｄ１）を横幅（ｄ２）よりも小さくしている。ただ、出力端子部は、金属線を部分的に押し潰してその横断面形状を楕円形として、Ｕ曲部の厚さ（ｄ１）を横幅（ｄ２）よりも小さくすることもできる。   In the output terminal portion 30 shown in FIGS. 14 and 15, the metal wire 8 is partially crushed so that the cross-sectional shape of the U-curved portion 30A is noncircular. The U-curved portion 30A shown in FIG. 15 has an oblong cross-sectional shape and a thickness (d1) smaller than the horizontal width (d2). However, the output terminal portion can partially crush the metal wire to make its cross-sectional shape elliptical, and the thickness (d1) of the U-curved portion can be made smaller than the lateral width (d2).

また、図１８と図１９に示す出力端子部３０は、全体の横断面形状を非円形とする金属線８Ｂを折曲加工してＵ曲部３０Ａの横断面形状を非円形としている。図１９に示すＵ曲部３０Ａは、金属線８Ｂの横断面形状を楕円形として、厚さ（ｄ１）を横幅（ｄ２）よりも小さくしている。ただ、出力端子部は、全体の横断面形状を長円形とする金属線を折曲加工してＵ曲部の厚さ（ｄ１）を横幅（ｄ２）よりも小さくすることもできる。   Further, in the output terminal portion 30 shown in FIGS. 18 and 19, the metal wire 8B having a non-circular overall cross-sectional shape is bent so that the cross-sectional shape of the U-curved portion 30A is non-circular. In the U-curved portion 30A shown in FIG. 19, the cross-sectional shape of the metal wire 8B is an ellipse, and the thickness (d1) is smaller than the horizontal width (d2). However, the thickness of the U-bent portion (d1) can be made smaller than the lateral width (d2) by bending a metal wire having an oval overall cross-sectional shape.

出力端子部３０は、Ｕ曲部３０Ａの厚さ（ｄ１）を、横幅（ｄ２）の１０％ないし８０％、好ましくは、３０％ないし７０％とする。出力端子部は、Ｕ曲部の厚さ（ｄ１）を小さくして、その曲率半径を小さくできる。ただ、Ｕ曲部の厚さ（ｄ１）が小さすぎると、Ｕ曲部の強度が低下する。また、出力端子部は、Ｕ曲部の横幅（ｄ２）を大きくして、その強度を高めることができる。ただ、Ｕ曲部の横幅（ｄ２）が大きすぎると、電源端子との接触部分が大きくなる。したがって、出力端子部は、これらのことを考慮して、Ｕ曲部３０Ａの厚さ（ｄ１）と横幅（ｄ２）を決定する。   In the output terminal portion 30, the thickness (d1) of the U-curved portion 30A is 10% to 80%, preferably 30% to 70% of the lateral width (d2). The output terminal portion can reduce the radius of curvature by reducing the thickness (d1) of the U-curved portion. However, if the thickness (d1) of the U-curved portion is too small, the strength of the U-curved portion decreases. Further, the output terminal portion can increase the strength by increasing the lateral width (d2) of the U-curved portion. However, if the width (d2) of the U-curved portion is too large, the contact portion with the power supply terminal becomes large. Therefore, the output terminal portion determines the thickness (d1) and the lateral width (d2) of the U-curved portion 30A in consideration of these points.

図１４と図１５に示す充電接点３の出力端子部３０は、横断面形状を円形とする金属線８Ａを両側から押し潰して、Ｕ曲部３０Ａを成形する部分の横断面形状を非円形としている。この出力端子部３０は、図１６の矢印Ａで示すように、プレス工程において、金属線８Ａを部分的に押し潰して横断面形状を非円形とした後、折曲工程において、図１６の矢印Ｂで示すように、非円形部８ａを所定の曲率半径でＵ曲してＵ曲部３０Ａを成形する。   The output terminal portion 30 of the charging contact 3 shown in FIGS. 14 and 15 crushes the metal wire 8A having a circular cross-sectional shape from both sides to make the cross-sectional shape of the portion forming the U-curved portion 30A noncircular. Yes. As shown by an arrow A in FIG. 16, the output terminal portion 30 is formed by partially crushing the metal wire 8A in the pressing process to make the cross-sectional shape noncircular, and then in the bending process, the arrow in FIG. As shown by B, the U-shaped portion 30A is formed by U-curving the non-circular portion 8a with a predetermined radius of curvature.

プレス工程は、図１６と図１７に示すように、横断面形状を円形とする金属線８Ａの一部分であって、Ｕ曲部３０Ａを設ける部分を直径方向に押し潰して、横断面形状を長円形または楕円形とする非円形部８ａとする。このプレス工程では、直径方向に押し潰される非円形部８ａの厚さ（ｄ１）が、金属線８Ａの直径（Ｄ）の３０％ないし９０％、好ましくは５０％ないし８０％となるように押し潰して非円形部８ａを成形する。さらに、直径方向に押し潰される金属線８Ａは、幅方向に広がって、横幅（ｄ２）が金属線８Ａの直径（Ｄ）よりも大きくなる。プレスされる非円形部８ａは、その横幅（ｄ２）が金属線８Ａの直径（Ｄ）の１００％ないし１５０％となるように押し潰すことができる。金属線８Ａは、非円形部８ａの厚さ（ｄ１）が横幅（ｄ２）の１０％ないし８０％、好ましくは、３０％ないし７０％となるようにプレスされる。図１４ないし図１７に示す出力端子部３０は、直径（Ｄ）を０．６ｍｍとする金属線８Ａを、厚さ（ｄ１）が０．４ｍｍ、横幅（ｄ２）が０．７ｍｍとなるまで押し潰して非円形部８ａとして、Ｕ曲部３０Ａの断面形状を非円形としている。   As shown in FIGS. 16 and 17, the pressing process is a part of the metal wire 8A having a circular cross-sectional shape, and the portion where the U-curved portion 30A is provided is crushed in the diametrical direction to increase the cross-sectional shape. The non-circular portion 8a is circular or elliptical. In this pressing step, the thickness (d1) of the non-circular portion 8a squeezed in the diametrical direction is 30% to 90%, preferably 50% to 80%, of the diameter (D) of the metal wire 8A. The non-circular portion 8a is formed by crushing. Further, the metal wire 8A crushed in the diameter direction spreads in the width direction, and the lateral width (d2) becomes larger than the diameter (D) of the metal wire 8A. The non-circular portion 8a to be pressed can be crushed so that the lateral width (d2) is 100% to 150% of the diameter (D) of the metal wire 8A. The metal wire 8A is pressed so that the thickness (d1) of the non-circular portion 8a is 10% to 80%, preferably 30% to 70% of the lateral width (d2). The output terminal 30 shown in FIGS. 14 to 17 pushes a metal wire 8A having a diameter (D) of 0.6 mm until the thickness (d1) is 0.4 mm and the lateral width (d2) is 0.7 mm. As a non-circular portion 8a, the cross-sectional shape of the U-curved portion 30A is non-circular.

折曲工程は、図１６の矢印Ｂで示すように、金属線８Ａを非円形部８ａでＵ曲してＵ曲部３０Ａを成形する。Ｕ曲されるＵ曲部３０Ａの曲率半径は、Ｕ曲部３０Ａの厚さ（ｄ１）に比例して小さくできる。折曲加工されるＵ曲部３０Ａは、内周面の曲率半径（Ｒ１）を厚さ（ｄ１）の０．８〜１．２倍とし、外周面の曲率半径（Ｒ２）を横幅（ｄ２）の１．６〜２．４倍とすることができる。図１４と図１５に示す出力端子部３０は、Ｕ曲部３０Ａの厚さ（ｄ１）を０．４ｍｍとして、Ｕ曲部３０Ａの内周面の曲率半径（Ｒ１）を０．４ｍｍ、Ｕ曲部３０Ａの外周面の曲率半径（Ｒ２）を０．８ｍｍとしている。これに対して、図３と図４に示す出力端子部８３ａでは、直径（Ｄ）を０．６ｍｍとする弾性金属線８０を折曲加工して、出力端子部８３ａの内周面の曲率半径（Ｒ１）を０．６ｍｍ、出力端子部８３ａの外周面の曲率半径（Ｒ２）を１．２ｍｍとしている。したがって、図１４に示す出力端子部３０は、図３に示す出力端子部８３ａに比較して、金属線の直径（Ｄ）を等しくしながら、Ｕ曲部の内周面の曲率半径（Ｒ１）と外周面の曲率半径（Ｒ２）を約２／３倍に小さくできる。   In the bending step, as shown by an arrow B in FIG. 16, the metal wire 8A is bent at a non-circular portion 8a to form a U bent portion 30A. The radius of curvature of the U-curved portion 30A to be U-curved can be reduced in proportion to the thickness (d1) of the U-curved portion 30A. The U-curved portion 30A to be bent has a radius of curvature (R1) of the inner peripheral surface of 0.8 to 1.2 times the thickness (d1) and a radius of curvature (R2) of the outer peripheral surface of the width (d2). 1.6 to 2.4 times as large as. 14 and 15, the thickness (d1) of the U-curved portion 30A is 0.4 mm, the radius of curvature (R1) of the inner peripheral surface of the U-curved portion 30A is 0.4 mm, and the U-curved portion is shown in FIGS. The radius of curvature (R2) of the outer peripheral surface of the portion 30A is 0.8 mm. On the other hand, in the output terminal portion 83a shown in FIGS. 3 and 4, the elastic metal wire 80 having a diameter (D) of 0.6 mm is bent, and the radius of curvature of the inner peripheral surface of the output terminal portion 83a. (R1) is 0.6 mm, and the radius of curvature (R2) of the outer peripheral surface of the output terminal portion 83a is 1.2 mm. Therefore, the output terminal portion 30 shown in FIG. 14 has a radius of curvature (R1) of the inner peripheral surface of the U-curved portion while making the diameter (D) of the metal wire equal compared to the output terminal portion 83a shown in FIG. And the radius of curvature (R2) of the outer peripheral surface can be reduced to about 2/3 times.

とくに、図１４の出力端子部３０は、横断面形状を円形とする金属線８Ａを折曲加工してＵ曲部３０Ａを設けながら、Ｕ曲部３０Ａの曲率半径を小さくできる。この充電接点３は、Ｕ曲部３０Ａにおける内周面の曲率半径（Ｒ１）を金属線８Ａの直径（Ｄ）の０．６〜０．９倍とし、また、外周面の曲率半径（Ｒ２）を金属線８Ａの直径（Ｄ）の１．２〜１．８倍として、Ｕ曲部３０Ａの曲率半径を小さくできる。   In particular, the output terminal portion 30 of FIG. 14 can reduce the radius of curvature of the U-curved portion 30A while bending the metal wire 8A having a circular cross-sectional shape to provide the U-curved portion 30A. The charging contact 3 has a radius of curvature (R1) of the inner peripheral surface of the U-curved portion 30A that is 0.6 to 0.9 times the diameter (D) of the metal wire 8A, and a radius of curvature (R2) of the outer peripheral surface. Is 1.2 to 1.8 times the diameter (D) of the metal wire 8A, and the radius of curvature of the U-curved portion 30A can be reduced.

さらに、図１８と図１９に示す出力端子部３０は、全体の横断面形状を非円形とする金属線８ＢをＵ曲してＵ曲部３０Ａを成形している。図１８に示す出力端子部３０も、Ｕ曲部３０Ａの厚さ（ｄ１）を０．４ｍｍ、横幅（ｄ２）を０．７ｍｍとして、Ｕ曲部３０Ａの内周面の曲率半径（Ｒ１）を０．４ｍｍ、Ｕ曲部３０Ａの外周面の曲率半径（Ｒ２）を０．８ｍｍとしている。この出力端子部３０も、図３に示す出力端子部８３ａに比較して、充電接点３の強度を低下させることなく、Ｕ曲部の内周面の曲率半径（Ｒ１）と外周面の曲率半径（Ｒ２）を約２／３倍に小さくできる。さらに、この充電接点は、図示しないが、横断面形状を楕円形とする金属線を螺旋状に巻いてコイル部を設けることができる。   Further, in the output terminal portion 30 shown in FIGS. 18 and 19, the U-curved portion 30A is formed by U-bending a metal wire 8B whose overall cross-sectional shape is non-circular. Also in the output terminal portion 30 shown in FIG. 18, the thickness (d1) of the U-curved portion 30A is 0.4 mm, the lateral width (d2) is 0.7 mm, and the radius of curvature (R1) of the inner peripheral surface of the U-curved portion 30A is set. The radius of curvature (R2) of the outer peripheral surface of the U-curved portion 30A is set to 0.4 mm and 0.8 mm. The output terminal portion 30 also has a radius of curvature (R1) of the inner peripheral surface of the U-curved portion and a radius of curvature of the outer peripheral surface without reducing the strength of the charging contact 3 as compared with the output terminal portion 83a shown in FIG. (R2) can be reduced to about 2/3 times. Furthermore, although this charging contact is not shown, a coil portion can be provided by spirally winding a metal wire having an elliptical cross-sectional shape.

コイル部３３は、弾性金属線を螺旋状に巻いており、出力端子部３０を装着部２に向かって付勢している。この充電接点３は、螺旋状に巻いたコイル部３３を連結ロッド１６に挿入して、凸条１０Ａの収納部１１に配設される。また、図の充電器は、第２アーム３２をケース１に連結しているが、これに代わって、第２アームを無くして、コイル部の金属線の端部を曲げて、ケースの連結ロッドに係止する等の構造を、適宜、採用することができる。   The coil portion 33 is formed by winding an elastic metal wire in a spiral shape and biases the output terminal portion 30 toward the mounting portion 2. The charging contact 3 is disposed in the storage portion 11 of the ridge 10 </ b> A by inserting a spirally wound coil portion 33 into the connecting rod 16.
