Description

本発明は、筐体外面に受電端子を有した携帯端末が載置された状態で上記受電端子に接触することにより充電する充電端子を備えた充電器に関する。   The present invention relates to a charger including a charging terminal that is charged by contacting the power receiving terminal in a state where a portable terminal having the power receiving terminal is placed on the outer surface of the housing.

例えば携帯電話機が充電器に載置された状態では、充電器の充電端子が携帯電話機の受電端子に導通することにより、携帯電話機に内蔵された電池パックに充電するようにしている。この充電端子は、携帯電話機が充電器に載置された状態で携帯電話機の受電端子に押されて没入することにより、受電端子に付勢された点接触状態で通電するようになっている。   For example, in a state where the mobile phone is placed on a charger, the charging terminal of the charger is connected to the power receiving terminal of the mobile phone to charge the battery pack built in the mobile phone. The charging terminal is energized in a point contact state urged by the power receiving terminal by being pushed and immersed in the power receiving terminal of the mobile phone while the mobile phone is placed on the charger.

このような充電端子を用いた充電では、充電端子の先端が酸化して接触不良を生じることがあることから、充電端子として円形状の接触端子により通電するものが提案されている。このような構成として、特許文献1のものでは、円型接触子を弾性状の接触部により導電対象面に対してほぼ垂直方向に圧接することにより通電するようにしている。
特開2001−244034号公報
In charging using such a charging terminal, the tip of the charging terminal may oxidize and cause a contact failure. Therefore, a charging terminal that is energized by a circular contact terminal has been proposed. As such a structure, in the thing of patent document 1, it is made to supply with electricity by pressing a circular contactor in a substantially perpendicular direction with respect to a conductive object surface by an elastic contact part.
JP 2001-244034 A

しかしながら、特許文献1のものは、円型接触子を弾性状の接触部により圧接させているため、接触による導電面とバネ圧による圧接面とが同じ面となり、摩耗による劣化が早い。また、十分なたわみ量をもったバネ特性が得られないために接触対象面の位置が変化した場合に追従しきれない(接触しない)と共に、端子相互の角度が傾いた場合に良好な接触状態が得られない等の問題があった。   However, in the case of Patent Document 1, since the circular contact is brought into pressure contact with the elastic contact portion, the conductive surface due to contact and the pressure contact surface due to spring pressure are the same surface, and deterioration due to wear is rapid. In addition, since the spring characteristics with sufficient deflection cannot be obtained, it cannot follow when the position of the contact target surface changes (does not contact) and is in good contact when the angle between the terminals is inclined. There were problems such as being unable to obtain.

本発明は上記事情に鑑みてなされたもので、その目的は、携帯端末を載置する際に、電気的な接触が安定していると共に、端子の摩耗寿命を延ばすことができる充電器を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a charger capable of stabilizing the electrical contact and extending the wear life of the terminal when the portable terminal is placed. There is to do.

請求項1の発明によれば、充電器に携帯端末を載置すると、回転接触端子が受電端子に接触する。このとき、回転接触端子は、支承端子により受電端子に圧接しているので、その圧接状態で回転する。これにより、接触による導電面とバネによる圧力面とが同じ面である構成に比較して、回転接触端子による受電端子に対する接触部位が変化し、摩耗による早期劣化、接触不良などを防止できる。
この場合、回転接触端子は球形状であり、いずれの方向にも回転可能に支承端子の受部で支持されているので、受電端子がいずれの方向に傾いた場合であっても、両者の接触状態が変わらず、両者の接触状態を良好に維持することができる。
According to invention of Claim 1, when a portable terminal is mounted in a charger, a rotation contact terminal contacts a receiving terminal. At this time, since the rotary contact terminal is in pressure contact with the power receiving terminal by the support terminal, it rotates in the pressure contact state. Thereby, compared with the structure in which the conductive surface due to contact and the pressure surface due to the spring are the same surface, the contact portion of the rotating contact terminal with respect to the power receiving terminal changes, and early deterioration due to wear, poor contact, and the like can be prevented.
In this case, the rotary contact terminal has a spherical shape and is supported by the receiving portion of the support terminal so as to be rotatable in any direction. Therefore, even if the power receiving terminal is inclined in any direction, the contact between the two is possible. The state does not change, and the contact state between the two can be maintained well.

請求項の発明によれば、複数のバネ部は独立して受電端子にほぼ垂直方向に圧接するので、受電端子に対する回転接触端子の圧接方向が傾くにしても、両者の接触状態を良好に維持することができる。 According to the invention of claim 2 , since the plurality of spring portions independently press contact with the power receiving terminal in a substantially vertical direction, even if the press contact direction of the rotary contact terminal with respect to the power receiving terminal is inclined, the contact state between the two is improved. Can be maintained.

The read information can be transmitted to the charger 1 side by optical communication.

In FIG. 1, the charger 1 includes a power supply circuit 6, a charging circuit 7, a charging detection circuit 8, and a communication control circuit 9. On the other hand, the portable barcode reader 2 includes a control unit 10, a warning unit 11, a communication circuit 12, and a secondary battery 13 for power supply.

充電検出回路8は、充電回路7による充電状態を監視しており、その充電状態を通信制御回路9を通じて携帯型バーコードリーダ2の通信回路12に送信する。
通信制御回路9はパソコン14と接続されており、携帯型バーコードリーダ2が読取ったコード情報をパソコン14に送信するようになっている。
In the charger 1, the charging circuit 7 charges the secondary battery 13 of the portable barcode reader 2 placed on the charger 1 through the charging terminal 5 and the power receiving terminal 4 in a power supply state from the power supply circuit 6.
The charge detection circuit 8 monitors the charging state by the charging circuit 7 and transmits the charging state to the communication circuit 12 of the portable barcode reader 2 through the communication control circuit 9.

携帯型バーコードリーダ2において、二次電池13は図示しない電源スイッチがオンに切換えられた状態で携帯型バーコードリーダ2の内部回路に給電すると共に、電源スイッチのオンオフ状態にかかわらず充電器1の充電回路7により充電されるようになっている。
制御部10は、通信回路12を通じて充電器1から通知された充電状態に基いて充電開始したかを判断し、充電開始しなかったときは充電不良であると判断して警音部11を駆動するようになっている。

The control unit 10 determines whether charging has started based on the state of charge notified from the charger 1 through the communication circuit 12. If the charging has not started, the control unit 10 determines that charging is defective and drives the alarm unit 11. It is supposed to be.

次に、充電器1の充電端子5の構造について説明する。
図3は充電端子5の分解斜視図である。この図3において、充電端子5は、支承端子15の先端に回転接触端子16を回転可能に支持するように構成されている。支承端子15は、弾性を有する例えば真鍮板を金型形成してなり、支柱部15aの先端に所定距離離間した二股状のバネ部15bを連結し、そのバネ部15bの先端に所定径の湾曲形状を形成する共に、その反対側に同一の湾曲形状の部材を接合して所定径の環状の受部15cを形成して構成されている。この支承端子15は、充電回路7と接続されており、充電回路7からの充電電流を受けるようになっている。
Next, the structure of the charging terminal 5 of the charger 1 will be described.
FIG. 3 is an exploded perspective view of the charging terminal 5. In FIG. 3, the charging terminal 5 is configured to rotatably support the rotary contact terminal 16 at the tip of the support terminal 15. The support terminal 15 is made of, for example, a brass plate having elasticity, and is connected to a bifurcated spring portion 15b separated by a predetermined distance at the tip of the support column 15a. In addition to forming the shape, a member having the same curved shape is joined to the opposite side to form an annular receiving portion 15c having a predetermined diameter. The support terminal 15 is connected to the charging circuit 7 and receives a charging current from the charging circuit 7.

回転接触端子16は、所定の直径を有する円筒状の転がり接点部16aと、この転がり接点部16aの中心軸に設けられた当該転がり接点部16aよりも直径が小さな回転支承部16bとから構成されている。この転がり接点部16aの表面は、接触状態が安定する金メッキが施されている。また、回転支承部16bは、摩擦抵抗が比較的小さい砲金などの銅合金から形成されている。   The rotary contact terminal 16 includes a cylindrical rolling contact portion 16a having a predetermined diameter, and a rotary support portion 16b having a diameter smaller than that of the rolling contact portion 16a provided on the central axis of the rolling contact portion 16a. ing. The surface of the rolling contact portion 16a is plated with gold that stabilizes the contact state. Moreover, the rotation support part 16b is formed from copper alloys, such as a gun metal with comparatively small frictional resistance.

上記構成の回転接触端子16の回転支承部16bは支承端子15の先端に形成された受部15cに挿入されており、その挿入状態で、図4に示すように回転接触端子16の転がり接点部16aが支承端子15の二股状のバネ部15b間に位置している。また、回転接触端子16が支承端子15に支持された形態では、図5(a)に示すように回転接触端子16が充電器1に形成された窓部17から内方に突出している。   The rotating support portion 16b of the rotating contact terminal 16 having the above-described configuration is inserted into a receiving portion 15c formed at the tip of the supporting terminal 15, and in the inserted state, as shown in FIG. 16 a is located between the bifurcated spring portions 15 b of the support terminal 15. Further, in the form in which the rotary contact terminal 16 is supported by the support terminal 15, the rotary contact terminal 16 protrudes inward from the window portion 17 formed in the charger 1 as shown in FIG.

さて、使用者が携帯型バーコードリーダ2による読取操作を終了して、充電器1を充電器1に載置すると、携帯型バーコードリーダ2の回転接触端子16が充電器1の受電端子4に接触するので、充電器1に設けられた充電回路7から携帯型バーコードリーダ2の二次電池13に充電開始される。
このように携帯型バーコードリーダ2を充電器1に載置した場合、携帯型バーコードリーダ2の受電端子4が充電器1の窓部17を通過するので、充電器1の窓部17から内方に突出していた充電端子5の回転接触端子16が携帯型バーコードリーダ2の受電端子4により押されて図5(b)に示す位置に移動する。
When the user finishes the reading operation by the portable barcode reader 2 and places the charger 1 on the charger 1, the rotary contact terminal 16 of the portable barcode reader 2 becomes the power receiving terminal 4 of the charger 1. Therefore, the secondary battery 13 of the portable barcode reader 2 starts to be charged from the charging circuit 7 provided in the charger 1.
When the portable barcode reader 2 is thus placed on the charger 1, the power receiving terminal 4 of the portable barcode reader 2 passes through the window portion 17 of the charger 1. The rotating contact terminal 16 of the charging terminal 5 protruding inward is pushed by the power receiving terminal 4 of the portable barcode reader 2 and moved to the position shown in FIG.

このとき、回転接触端子16が受電端子4に押圧した状態で受電端子4が移動するので、受電端子4の移動に伴って回転接触端子16が回転し、受電端子4の接触位置が変化するようになる。
また、図5(b)に示すように回転接触端子16が移動した状態では、回転接触端子16が支承端子15を構成するバネ部15bの弾性力により受電端子4に圧接するので、十分なたわみ量を有したバネ部15bにより回転接触端子16を受電端子4に確実に接触させることができる。尚、本発明で言う圧接とは、圧力を付勢した状態で部材同士が接するという意味であり、接合を意味するものではない。
At this time, since the power receiving terminal 4 moves in a state where the rotating contact terminal 16 is pressed against the power receiving terminal 4, the rotating contact terminal 16 rotates with the movement of the power receiving terminal 4 so that the contact position of the power receiving terminal 4 changes. become.
Further, when the rotary contact terminal 16 is moved as shown in FIG. 5 (b), the rotary contact terminal 16 is pressed against the power receiving terminal 4 by the elastic force of the spring portion 15 b constituting the support terminal 15. The rotary contact terminal 16 can be reliably brought into contact with the power receiving terminal 4 by the spring portion 15b having a large amount. In addition, the press contact referred to in the present invention means that the members are in contact with each other in a state where the pressure is applied, and does not mean joining.

このような参考例によれば、充電端子5を構成する回転接触端子16として、径大な転がり接点部16aを径小な回転支承部16bを介して支承端子15で支持することにより、携帯型バーコードリーダ2を充電器1に載置する際に回転接触端子16が携帯型バーコードリーダ2の受電端子4に圧接状態で回転するようにしたので、接触による導電面とバネ圧による圧力面とが同じ面である従来例のものと違って、回転接触端子16による受電端子4に対する接触部位が変化し、摩耗による早期劣化を防止することができる。 According to such a reference example, the rotary contact terminal 16 constituting the charging terminal 5 is supported by the support terminal 15 via the rotary support part 16b having a small diameter as a portable contact type. When the barcode reader 2 is placed on the charger 1, the rotary contact terminal 16 is rotated in pressure contact with the power receiving terminal 4 of the portable barcode reader 2. Therefore, the conductive surface due to contact and the pressure surface due to spring pressure. Unlike the conventional example having the same surface, the contact portion of the rotary contact terminal 16 with the power receiving terminal 4 changes, and early deterioration due to wear can be prevented.

また、回転接触端子16を、バネ部15bを有した支承端子15で支承することにより十分なたわみ量を有したもったバネ特性を得られるようにしたので、携帯型バーコードリーダ2の受電端子4の傾きが変化した場合であっても、その変化に追従することができ、携帯型バーコードリーダ2を安定して充電することができる。   Further, since the rotary contact terminal 16 is supported by the support terminal 15 having the spring portion 15b, a spring characteristic having a sufficient amount of deflection can be obtained, so that the power receiving terminal of the portable barcode reader 2 can be obtained. Even if the inclination of 4 changes, the change can be followed and the portable barcode reader 2 can be charged stably.

(第2参考例)
次に本発明の第2参考例について図6及び図7を参照して説明する。この第2参考例は、第1参考例で示した充電端子の回転接触端子の形状を工夫したものである。
充電端子を示す図6において、充電端子21を構成する回転接触端子22は、中心となる程径大となる膨出形状に形成されており、支承端子23を構成するバネ部23aの先端に設けられた受部23bで回転可能に支持されている。
このような構成の受電端子21を有した充電器1に携帯型バーコードリーダ2を載置すると、携帯型バーコードリーダ2の受電端子4に対して回転接触端子22の最も径大な中央部が接触するので、図6に示すように回転接触端子22を受電端子4に確実に接触させることができる。
(Second reference example)
Next, a second reference example of the present invention will be described with reference to FIGS. In the second reference example, the shape of the rotary contact terminal of the charging terminal shown in the first reference example is devised.
In FIG. 6 showing the charging terminal, the rotating contact terminal 22 constituting the charging terminal 21 is formed in a bulging shape having a diameter that increases toward the center, and is provided at the tip of the spring portion 23 a constituting the support terminal 23. The receiving portion 23b is rotatably supported.
When the portable barcode reader 2 is placed on the charger 1 having the power receiving terminal 21 having such a configuration, the center portion having the largest diameter of the rotary contact terminal 22 with respect to the power receiving terminal 4 of the portable barcode reader 2. Therefore, the rotary contact terminal 22 can be reliably brought into contact with the power receiving terminal 4 as shown in FIG.

また、携帯型バーコードリーダ2の受電端子4が傾いた場合は、図7に示すように回転接触端子22の中央部から外れた部位が受電端子4に対してほぼ垂直方向に圧接するので、受電端子4に傾きが発生した場合であっても、回転接触端子22による受電端子4に対する良好な接触状態を維持することができる。   Further, when the power receiving terminal 4 of the portable barcode reader 2 is tilted, the portion removed from the central portion of the rotary contact terminal 22 is pressed in a substantially vertical direction with respect to the power receiving terminal 4 as shown in FIG. Even when the power receiving terminal 4 is inclined, a good contact state with the power receiving terminal 4 by the rotary contact terminal 22 can be maintained.

(第実施例)
次に本発明の第実施例について図8及び図9を参照して説明する。この第実施例は、回転接触端子を球形状としたことに特徴を有する。
充電端子を示す図8において、充電端子31を構成する回転接触端子32は球形状をなしており、その球形状の中心に対して対称となる2箇所で支承端子33を構成するバネ部33aの先端に設けられた受部33bにより回転可能に支持されている。即ち、図9に示すように支承端子33の先端に形成された受部33bの内面は凹面をなしており、その凹面により回転接触端子32の対向する2箇所の凸面を摺動自在に支持している。
(First Embodiment)
Next, a first embodiment of the present invention will be described with reference to FIGS. The first embodiment is characterized in that the rotary contact terminal has a spherical shape.
In FIG. 8 which shows a charging terminal, the rotation contact terminal 32 which comprises the charging terminal 31 is carrying out spherical shape, and the spring part 33a which comprises the support terminal 33 in two places symmetrical with respect to the spherical-shaped center. A receiving portion 33b provided at the tip is rotatably supported. That is, as shown in FIG. 9, the inner surface of the receiving portion 33b formed at the tip of the support terminal 33 is concave, and the concave surfaces support the two convex surfaces facing the rotary contact terminal 32 slidably. ing.

このような構成の充電端子31を有した充電器1に携帯型バーコードリーダ2を載置すると、回転接触端子32が携帯型バーコードリーダ2の受電端子4に接触して回転するので、携帯型バーコードリーダ2の受電端子4への接触部位を変化させることができる。
また、携帯型バーコードリーダ2の受電端子4が傾いた場合であっても、第2参考例と同様に、受電端子4に対して回転接触端子32をほぼ垂直に接触することができ、安定した接触を得ることができる。
When the portable barcode reader 2 is placed on the charger 1 having the charging terminal 31 having such a configuration, the rotary contact terminal 32 rotates in contact with the power receiving terminal 4 of the portable barcode reader 2. The contact part to the power receiving terminal 4 of the type barcode reader 2 can be changed.
Further, even when the power receiving terminal 4 of the portable barcode reader 2 is tilted, the rotary contact terminal 32 can be brought into substantially vertical contact with the power receiving terminal 4 in the same manner as in the second reference example. Contact can be obtained.

さらに、回転接触端子32が球形状であることから、携帯型バーコードリーダ2の受電端子4のどのような傾きに対しても追従することができると共に、回転接触端子32の球面全体を接触面として使用することができ、回転接触端子32の早期摩耗を一層防止することができる。   Further, since the rotary contact terminal 32 has a spherical shape, it can follow any inclination of the power receiving terminal 4 of the portable barcode reader 2, and the entire spherical surface of the rotary contact terminal 32 can be contacted with the contact surface. As a result, early wear of the rotary contact terminal 32 can be further prevented.

(第実施例)
次に本発明の第実施例について図10に基づいて説明する。この第実施例は、回転接触端子の両端を独立して支持したことを特徴とする。
受電端子の支承端子を示す図10において、充電端子41を構成する支承端子42は、2個の独立したバネ部42aの先端に受部42bを有してなり、その受部42bに回転接触端子16の両側を独立に回転可能に支持するようになっている。
このような構成の接触端子を有した充電器1に携帯型バーコードリーダ2を載置すると、回転接触端子16が携帯型バーコードリーダ2の受電端子4によって押され、回転接触端子16を支持している支承端子42が撓むようになる。この場合、支承端子42は、回転接触端子16の両側を独立に支持しているので、携帯型バーコードリーダ2の受電端子4との相互の角度変動に確実に対応することができる。
(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment is characterized in that both ends of the rotary contact terminal are supported independently.
In FIG. 10 showing the support terminal of the power receiving terminal, the support terminal 42 constituting the charging terminal 41 has a receiving part 42b at the tip of two independent spring parts 42a, and the rotary contact terminal is connected to the receiving part 42b. Both sides of 16 are rotatably supported independently.
When the portable barcode reader 2 is placed on the charger 1 having the contact terminal having such a configuration, the rotary contact terminal 16 is pushed by the power receiving terminal 4 of the portable barcode reader 2 to support the rotary contact terminal 16. The supporting terminal 42 is bent. In this case, since the support terminal 42 supports both sides of the rotary contact terminal 16 independently, the support terminal 42 can reliably cope with the mutual angle fluctuation with the power receiving terminal 4 of the portable barcode reader 2.

本発明は、上記実施例或いは参考例に限定されることなく、次のように変形または拡張できる。
複数の回転接触端子16を支承端子15で支持するように構成してもよい。
回転接触端子16が回転する際に、横方向にスライドすることにより受電端子4に対する接触位置を変化させるようにしてもよい。
The present invention is not limited to the above-described embodiments or reference examples, and can be modified or expanded as follows.
A plurality of rotary contact terminals 16 may be supported by the support terminals 15.
When the rotary contact terminal 16 rotates, the contact position with respect to the power receiving terminal 4 may be changed by sliding in the lateral direction.
