Description
本発明は、ＰＤＡ，携帯電話およびハンディターミナルの充電装置等、電子機器の充電端子構造に関するものである。 The present invention relates to a charging terminal structure of an electronic device such as a PDA, a mobile phone, and a charging device for a handy terminal.
近年、流通しているＰＤＡ、携帯電話及びハンディターミナル等の情報機器は一般的にリチウムイオン型、ニッケル水素型といった充電式の二次電池で駆動する。そして充電式の二次電池で駆動する電子機器のほとんどが、電子機器本体の任意の場所に配置された充電端子と機器専用の充電装置の端子を接触させることによって、情報機器に電池を挿入したまま充電作業が行われる。その時、電子機器本体の充電端子は金属が剥き出しの状態であるため、誤って充電端子の電源側とＧＮＤ側を接触させやすく、電子機器の故障の原因となっていた。 In recent years, information devices such as PDAs, mobile phones, and handy terminals that are distributed in general are driven by rechargeable secondary batteries such as lithium ion type and nickel hydrogen type. And most electronic devices that are driven by rechargeable secondary batteries inserted batteries into information devices by bringing the charging terminals located anywhere in the electronic device body into contact with the terminals of the dedicated charging device. Charging work is performed as it is. At that time, since the charging terminal of the electronic device main body is in a state where the metal is exposed, it is easy to accidentally contact the power supply side and the GND side of the charging terminal, causing a failure of the electronic device.
上記問題点を解決するために、例えば特許文献１が提案されており、以下のように構成されている。すなわち、充電装置には正負２本の充電端子が突出して設けられており、また、情報機器本体の筐体には、充電式電池に導通した接点板が固定され、且つこの接点板と一定の距離を空けて、２本の中間接点ピンが設けられている。充電装置を情報機器本体に挿入すると、充電装置の正負２本の充電端子が、情報機器本体の中間接点ピンを押圧する。すると押圧された中間接点ピンは摺動して接点板に接触し、電気的に導通状態となることで充電が始まるといったものである。
しかしながら、上記従来の充電端子構造は、情報機器本体の中間接点ピンを押圧することにより、これが直線上に摺動して接点板と接触し、充電式電池に導通するという構造である。そのため、上記のような構成を以っても中間接点ピンを押圧すると充電装置の端子以外でも電気的に導通させることができるため、充電端子を誤って短絡させてしまう場合など電源間の短絡を完全に防止できる訳ではない。また、充電装置の端子に関しては常に電気的に導通されていることに加えて、端子が突出した構造のため、誤って端子短絡させる可能性が高く、電源間短絡が容易に起こり得るという問題を有している。
本発明は上記課題を鑑みてなされたものであり、その目的とするところは、以下のようなものである。すなわち、情報機器などの電子機器本体に配置された接点端子を充電装置以外で押圧するだけでは電気的に導通せず、誤った電源間短絡を防止することが可能な電子機器の端子を提供することである。
また、充電装置の端子に関しても、非充電時は電気的に非導通な端子とすることで、容易に電源間の短絡が起こらない端子を実現することを目的とする。
However, the conventional charging terminal structure described above is a structure in which when the intermediate contact pin of the information device main body is pressed, it slides on a straight line, contacts the contact plate, and conducts to the rechargeable battery. For this reason, even if the intermediate contact pin is pressed even if it is configured as described above, it can be electrically connected to terminals other than the terminals of the charging device. It cannot be completely prevented. In addition to the fact that the terminals of the charging device are always electrically connected, there is a high possibility that the terminals will be short-circuited accidentally due to the protruding structure of the terminals, and a short circuit between the power supplies can easily occur. Have.
The present invention has been made in view of the above-mentioned problems, and the object of the present invention is as follows. That is, it provides a terminal of an electronic device that is not electrically connected only by pressing a contact terminal disposed on an electronic device body such as an information device with a device other than a charging device, and that can prevent an erroneous short circuit between power supplies. That is.
Also, with respect to the terminals of the charging device, it is an object to realize a terminal that does not easily cause a short circuit between power sources by being an electrically non-conductive terminal during non-charging.
上記課題を解決するために、請求項１に記載の発明は、以下のように構成した電子機器の端子構造を提供する。すなわち、電子機器間を電気的に接続する一対の接点端子であって、少なくとも前記一方の電子機器の接点端子は、他方の電子機器の接点端子で押圧されることにより回転する回転機構を有し、前記一方の接点端子と前記他方の接点端子は、それぞれ、一方に凸部を、他方に凹部を設け、それらが互いに係合するように対応した任意の形状を有し、該回転により前記電子機器間が導通状態になることを特徴としている。 In order to solve the above-mentioned problems, the invention according to claim 1 provides a terminal structure of an electronic device configured as follows. That is, a pair of contact terminals that electrically connect electronic devices, and at least one contact terminal of the electronic device has a rotation mechanism that rotates when pressed by the contact terminal of the other electronic device. The one contact terminal and the other contact terminal each have a convex portion on one side and a concave portion on the other, and have an arbitrary shape corresponding to the engagement with each other. It is characterized by the electrical connection between devices.
本発明によれば、電子機器本体に配置された接点端子を充電装置以外で押圧しただけでは、接点端子が電気的に導通せず、対となる充電装置などの電子機器の端子により押圧するときに電気的に導通される構造により、不要な電気的な電源間短絡を防止することができる。
また、充電装置などの電子機器の端子に関しても、電気的に非導通な端子を押圧することにより電気的に導通される構造により、誤った端子間の短絡を防ぐことができる。
According to the present invention, the contact terminal is not electrically connected only by pressing the contact terminal arranged on the electronic device main body other than the charging device, and is pressed by the terminal of the electronic device such as a pair of charging device. Due to the structure that is electrically connected to each other, it is possible to prevent unnecessary electrical short circuit between the power sources.
In addition, regarding terminals of electronic devices such as a charging device, a short circuit between erroneous terminals can be prevented by a structure in which electrical terminals are electrically connected by pressing an electrically non-conductive terminal.

まず情報機器及び充電装置の各接点端子、メス端子及びオス端子のそれぞれの構成について簡単に説明する。
メス端子軸１０６を押圧すると、メス端子１０１は、図２に示したメス端子軸１０６の頭部１０６ａがロック部１１０に突き当たるまで、情報機器筐体ガイド１０４に沿って情報機器接点板１０３の対向方向に直線的に上方に移動する。このときメス端子の頭部１０６ａがロック部１１０にかかることによって、メス端子の移動が規制され、メス端子接触カップ１０５は情報機器接点板１０３に接触しない位置で止められる。
すなわち、メス端子軸１０６の頭部１０６ａは、情報機器筐体ガイド１０４のロック部１１０の形状に対応した切り欠き部を有している。そして、図４に示すように頭部１０６ａがロック部１１０に当接したときに、図６（ハ）に示すように頭部１０６ａの切り欠き部がロック部１１０に対して略直交する位置にくるように頭部１０６ａを配置する。このような構成によって、非充電時に誤ってメス端子１０１を押してしまっても、メス端子接触カップ１０５が情報機器接点板１０３と接触しないため、誤った端子の短絡を防止することができる。
First, the configuration of each contact terminal, female terminal, and male terminal of the information device and the charging device will be briefly described.
When the female terminal shaft 106 is pressed, the female terminal 101 faces the information device contact plate 103 along the information device housing guide 104 until the head portion 106a of the female terminal shaft 106 shown in FIG. Move upwards linearly in the direction. At this time, the head 106a of the female terminal is engaged with the lock portion 110, so that the movement of the female terminal is restricted, and the female terminal contact cup 105 is stopped at a position where it does not contact the information device contact plate 103.
That is, the head portion 106 a of the female terminal shaft 106 has a notch corresponding to the shape of the lock portion 110 of the information equipment housing guide 104. When the head portion 106a comes into contact with the lock portion 110 as shown in FIG. 4, the notch portion of the head portion 106a is positioned substantially orthogonal to the lock portion 110 as shown in FIG. The head portion 106a is arranged so as to move. With such a configuration, even if the female terminal 101 is accidentally pressed during non-charging, the female terminal contact cup 105 does not come into contact with the information device contact plate 103, and thus an erroneous terminal short circuit can be prevented.
また、非充電時に、充電装置の端子以外で押圧するだけで容易にメス端子１０１が回転してロック部を通過してしまい、メス端子接触カップ１０５が情報機器接点板１０３に接触してしまうのを避けるため、以下のような構成を持つ。すなわち、図２の点線で囲まれたＢに示すとおり、メス端子接触カップ１０５は平らな側面を持ち、また、情報機器筐体ガイド１０４は先のロック部１１０とは別に、凸状の形状を持っている。これにより、非充電時に誤ってメス端子１０１が回転してしまうことを防止している。
またこの構成により、メス端子接触カップ１０５が回転しないため、これに設けられたメス端子回転ピン１０８を、図３中、メス端子軸１０６の左右方向に対して固定する。これによって、メス端子回転ピン１０８に対してメス端子軸１０６をメス端子スクリュー溝１０９に沿って移動可能にするという機構が機能するようにしている。
In addition, when not charging, the female terminal 101 easily rotates and passes through the lock portion simply by pressing other than the terminal of the charging device, and the female terminal contact cup 105 contacts the information device contact plate 103. In order to avoid this, it has the following configuration. That is, as shown by B surrounded by a dotted line in FIG. 2, the female terminal contact cup 105 has a flat side surface, and the information device housing guide 104 has a convex shape separately from the lock portion 110. have. This prevents the female terminal 101 from being accidentally rotated during non-charging.
Further, since the female terminal contact cup 105 does not rotate with this configuration, the female terminal rotation pin 108 provided on the cup is fixed with respect to the left-right direction of the female terminal shaft 106 in FIG. Thus, a mechanism for enabling the female terminal shaft 106 to move along the female terminal screw groove 109 with respect to the female terminal rotating pin 108 functions.
一方、オス端子接触ヘッド２０５に押圧をかけると、オス端子回転ピン２０８がオス端子スクリュー溝２０９に案内されて移動する。このとき、オス端子スクリュー溝２０９のスクリュー形状によって、オス端子回転ピン２０８が突設されているオス端子接触ヘッド２０５は回転するとともに、充電装置筐体ガイド２０４に沿って、充電装置接点板２０３に向かって下方に移動する。 On the other hand, when the male terminal contact head 205 is pressed, the male terminal rotating pin 208 is guided and moved by the male terminal screw groove 209. At this time, due to the screw shape of the male terminal screw groove 209, the male terminal contact head 205 on which the male terminal rotation pin 208 is protruded rotates, and the charging device contact plate 203 extends along the charging device housing guide 204. Move downwards.
さらにメス端子とオス端子との構成について説明する。
図６に示すように、メス端子軸１０６の先端にはネジのようなプラス型の窪み（凹部）を設け、対となるオス端子接触ヘッド２０５の先端にはドライバーのようなプラス型の出っ張り（凸部）を設けている。これらを係合すると、ドライバーとネジの関係と同じ原理で、対となるオス端子接触ヘッド２０５が回転することによって、オス端子接触ヘッド２０５と係合されるメス端子軸１０６を連動して回転させることができる。
Furthermore, the structure of a female terminal and a male terminal is demonstrated.
As shown in FIG. 6, a plus-type depression (concave portion) such as a screw is provided at the tip of the female terminal shaft 106, and a plus-type protrusion such as a screwdriver is provided at the tip of the paired male terminal contact head 205 ( (Convex part) is provided. When these are engaged, the female terminal shaft 106 engaged with the male terminal contact head 205 is rotated in conjunction with the rotation of the paired male terminal contact head 205 on the same principle as the relationship between the screwdriver and the screw. be able to.
ここで、本発明の実施の形態における情報機器１００、充電装置２００の端子構造の動作について説明する。
図３に示す通り、情報機器１００が充電装置２００に設置されていないときはメス端子接触カップ１０５、オス端子接触ヘッド２０５共に情報機器接点板１０３、充電装置接点板２０３に接触しないため各内部基板とは非導通である。
このとき、何らかの原因でメス端子１０１に押圧が加えられても、図６（ハ）の通り、メス端子軸１０６がロック部１１０にかかり移動が規制されることによって、メス端子接触カップ１０５と情報機器接点板１０３とは接触せず、誤った各端子間の短絡を防止することができる。
Here, the operation of the terminal structure of the information device 100 and the charging device 200 in the embodiment of the present invention will be described.
As shown in FIG. 3, when the information device 100 is not installed on the charging device 200, the female terminal contact cup 105 and the male terminal contact head 205 are not in contact with the information device contact plate 103 and the charging device contact plate 203. Is non-conductive.
At this time, even if the female terminal 101 is pressed for some reason, as shown in FIG. 6C, the movement of the female terminal shaft 106 is restricted by the lock portion 110, and the movement of the female terminal contact cup 105 is restricted. It is possible to prevent an erroneous short circuit between the terminals without contacting the device contact plate 103.
次に図４に示す通り、情報機器１００を充電装置２００に設置するようメス端子軸１０６のプラス型の窪みをオス端子接触ヘッド２０５のプラス型の出っ張りに係合して押圧すると、メス端子１０１は、メス端子軸１０６の頭部１０６ａがロック部１１０に突き当たるまで直線上に押し上げられる。このとき頭部１０６ａがロック部１１０にかかり、メス端子１０１の移動が規制される。 Next, as shown in FIG. 4, when the positive depression of the female terminal shaft 106 is engaged with the positive protrusion of the male terminal contact head 205 and pressed so that the information apparatus 100 is installed in the charging device 200, the female terminal 101 is pressed. Is pushed straight up until the head portion 106a of the female terminal shaft 106 abuts against the lock portion 110. At this time, the head 106a is engaged with the lock portion 110, and the movement of the female terminal 101 is restricted.
メス端子の頭部１０６ａがロック部にかかることによって、オス端子接触ヘッド２０５にとって上方が固定されるため、オス端子接触ヘッド２０５は、充電機器筐体ガイドに沿って、充電機器接点板に対して下方に押圧される。このとき、下方に押圧されるとともに、オス端子回転ピン２０８がオス端子スクリュー溝２０９に沿って移動することによって、オス端子接触ヘッド２０５は図４に示す矢印の方向に回転する。
またこのとき、図６に示すように、このオス端子接触ヘッド２０５の回転と連動してメス端子軸１０６が、メス端子スクリュー溝１０９に沿ってメス端子回転ピン１０８に案内されて共に回転する。これによって、図６（ハ）の状態から図６（ニ）の状態のように、頭部１０６ａがロック部１１０に対して９０度回転したところでメス端子軸１０６のロックが解除される。
Since the upper portion of the female terminal head portion 106a is fixed to the male terminal contact head 205 when the female terminal head portion 106a is engaged with the lock portion, the male terminal contact head 205 is positioned along the charging device housing guide with respect to the charging device contact plate. Pressed downward. At this time, while being pressed downward, the male terminal rotating pin 208 moves along the male terminal screw groove 209, whereby the male terminal contact head 205 rotates in the direction of the arrow shown in FIG.
At this time, as shown in FIG. 6, the female terminal shaft 106 is guided along the female terminal screw groove 109 by the female terminal rotating pin 108 and rotates together with the rotation of the male terminal contact head 205. As a result, as shown in FIG. 6C to the state of FIG. 6D, the lock of the female terminal shaft 106 is released when the head 106a rotates 90 degrees with respect to the lock portion 110.
