Description

本発明は、ＩＣカードの接続を行うＩＣカード用コネクタに関する。   The present invention relates to an IC card connector for connecting an IC card.

従来、この種のＩＣカード用コネクタとしては、下記に示すような構造のものが提案されていた。   Conventionally, as this type of IC card connector, one having the following structure has been proposed.

まず、従来のＩＣカード用コネクタの構造について図面を参照して説明する。ここで、
図３は従来のＩＣカード用コネクタの正面図、図４は図３のＸ-Ｘ線断面図である。 First, the structure of a conventional IC card connector will be described with reference to the drawings. here,
FIG. 3 is a front view of a conventional IC card connector, and FIG. 4 is a sectional view taken along line XX of FIG.

図示のように従来のＩＣカード用コネクタ１は、コネクタハウジング２に、ＩＣカードＡを挿入するためのカード挿入通路３が設けらけれている。カード挿入通路３は、対向する広面３ａと対向する挟面３ｂとで断面長方形状に形成されている。コネクタハウジング２内には、カード挿入通路３に臨ませてＩＣカードＡの各板状電極に接触させる各コンタクト４が組み込まれている
コネクタハウジング２内には、カード挿入通路３の脇にハートカム式ロック機構５が組み込まれている。ハートカム式ロック機構５は、カード挿入通路３にＩＣカードＡが挿入されたときにロックし、ロック状態のＩＣカードＡに再度押し込み力が加わったときにはこのＩＣカードＡをカード挿入通路３の手前側に戻す構造になっている。 As shown in the figure, a conventional IC card connector 1 is provided with a card insertion passage 3 for inserting an IC card A in a connector housing 2. The card insertion passage 3 is formed in a rectangular cross section with a wide surface 3a facing and a sandwiching surface 3b facing each other. In the connector housing 2, contacts 4 are incorporated so as to face the card insertion passages 3 and come into contact with the respective plate-like electrodes of the IC card A. In the connector housing 2, a heart cam type is located beside the card insertion passages 3. A lock mechanism 5 is incorporated. The heart cam type lock mechanism 5 locks when the IC card A is inserted into the card insertion passage 3, and when the pushing force is applied again to the IC card A in the locked state, the IC card A is moved to the front side of the card insertion passage 3. It has a structure to return to.

本例のハートカム式ロック機構５は、基本的には、ハートカム６が設けられていて前後にスライドするスライダー７と、このスライダー７上にハートカム６の周囲と奥側に向けて設けられたガイド溝８と、基端の折り曲げ部９ａがコネクタハウジング２の奥側に回転自在に支持され、先端の折り曲げ部９ｂがガイド溝８に嵌められているロックピン９と、基端がコネクタハウジング２の奥側に当接され、先端がスライダー７に当接されてこのスライダー７をカード挿入通路３の手前側に戻すコイルスプリング１０と、スライダー７の奥部に一体に設けられて挿入されたＩＣカードＡの奥部を受けるカード受け部１１とを備えた構造になっている。ハートカム６の外周部分に存在するガイド溝８の部分は、ロックピン９の先端の折り曲げ部９ｂが一方向にのみ回れるように各部分で底面が進行方向に傾斜面として上昇し、次の傾斜面との境界で段差部となって次の傾斜面の最低部に続くようになっている（例えば、特許文献１参照。）。   The heart cam type lock mechanism 5 of this example basically includes a slider 7 that is provided with a heart cam 6 and slides back and forth, and guide grooves provided on the slider 7 toward the periphery and the rear side of the heart cam 6. 8, a bent portion 9 a at the base end is rotatably supported on the back side of the connector housing 2, a lock pin 9 having a bent portion 9 b at the tip end fitted in the guide groove 8, and a base end at the back of the connector housing 2 A coil spring 10 whose tip is in contact with the slider 7 and returns the slider 7 to the front side of the card insertion passage 3, and an IC card A which is integrally provided at the back of the slider 7 and inserted. And a card receiving part 11 for receiving the back part of the card. The portion of the guide groove 8 existing on the outer peripheral portion of the heart cam 6 rises as an inclined surface in the traveling direction so that the bent portion 9b at the tip of the lock pin 9 can rotate only in one direction, and the next inclination It becomes a step part at the boundary with the surface and continues to the lowest part of the next inclined surface (see, for example, Patent Document 1).

このようなＩＣカード用コネクタ１では、操作者の操作でＩＣカードＡがカード挿入通路３に押し込まれ、このＩＣカードＡの押し込みによりカード受け部１１を介してスライダー７が奥に押し込まれ、このスライダー７の押し込み動作で、停止状態のロックピン９の先端の折り曲げ部９ｂが相対的に前に出て、この折り曲げ部９ｂがハートカム６の外周部分で両側の円弧状部がなす凹部６ａの所に回ってきたときにスライダー７がロックされ、ＩＣカードＡがカード挿入通路３内の所定の位置に置かれ、電気的な接続になる。スライダー７が奥に押し込まれると、コイルスプリング１０が圧縮されて蓄勢される。この状態で、ＩＣカードＡの外に出ている端部を再度押し込むと、カード受け部１１を介してスライダー７が再度奥に押し込まれ、このスライダー７の押し込み動作で、停止状態のロックピン９の先端の折り曲げ部９ｂが相対的に前に出て、この折り曲げ部９ｂがハートカム６の外周の凹部６ａから外れて再度一方向に回り出す。この動作でロックピン９の先端の折り曲げ部９ｂが、前後方向に延びるガイド溝８の直線部分に入り、コイルスプリング１０の蓄勢により、スライダー７が手前側に戻され、ＩＣカードＡが外に出るのでカード挿入通路３から取り出す。
特開２００３−３１７８６１号公報 図１ In such an IC card connector 1, the IC card A is pushed into the card insertion passage 3 by the operator's operation, and the slider 7 is pushed into the back via the card receiving portion 11 by pushing in the IC card A. When the slider 7 is pushed in, the bent portion 9b at the tip of the lock pin 9 in a stopped state comes out relatively forward, and this bent portion 9b is located at the concave portion 6a formed by the arc-shaped portions on both sides at the outer peripheral portion of the heart cam 6. The slider 7 is locked, and the IC card A is placed at a predetermined position in the card insertion path 3 to be electrically connected. When the slider 7 is pushed inward, the coil spring 10 is compressed and stored. In this state, when the end portion outside the IC card A is pushed in again, the slider 7 is pushed back through the card receiving portion 11, and the locking pin 9 in the stopped state is pushed by the pushing operation of the slider 7. The bent portion 9b at the tip of the head comes out relatively forward, and the bent portion 9b comes out of the concave portion 6a on the outer periphery of the heart cam 6 and turns around in one direction again. By this operation, the bent portion 9b at the tip of the lock pin 9 enters the linear portion of the guide groove 8 extending in the front-rear direction, and the slider 7 is returned to the front side by the accumulation of the coil spring 10, so that the IC card A is exposed to the outside. Since it comes out, it is taken out from the card insertion passage 3.
Japanese Patent Laid-Open No. 2003-317861 FIG.

しかしながら、このようなＩＣカード用コネクタ１では、ＩＣカードＡをコネクタハウジング２から外そうとして、ＩＣカードＡの外に出ている端部を再度押し込み、カード受け部１１を介してスライダー７を再度奥に押し込んで、ロックピン９の折り曲げ部９ｂをハートカム６の外周の凹部６ａから外すと、コイルスプリング１０の蓄勢力でスライダー７が手前側に一気に戻され、ＩＣカードＡが外に出る際にこのＩＣカードＡがコネクタハウジング２の外に放り出される場合があった。   However, in such an IC card connector 1, the end of the IC card A is pushed again to try to remove the IC card A from the connector housing 2, and the slider 7 is moved again via the card receiving part 11. When the bent portion 9b of the lock pin 9 is pushed away from the concave portion 6a on the outer periphery of the heart cam 6, the slider 7 is returned to the front side by the stored force of the coil spring 10, and the IC card A comes out. In some cases, the IC card A is thrown out of the connector housing 2.

本発明の目的は、コイルスプリングの蓄勢力でＩＣカードが外に出される際に、コネクタハウジングの外に放り出されるのを防止できるＩＣカード用コネクタを提供することにある。   An object of the present invention is to provide a connector for an IC card that can prevent the IC card from being ejected out of the connector housing when the IC card is ejected by a stored force of a coil spring.

上記の如き課題を解決し、所期の目的を達成する本発明のＩＣカード用コネクタの構成を説明すると、次のとおりである。   The configuration of the IC card connector of the present invention that solves the above-described problems and achieves the intended purpose will be described as follows.

請求項１に記載の発明は、コネクタハウジング内にＩＣカードを挿入するために対向する広面と対向する挟面とでカード挿入通路が設けられ、前記カード挿入通路内に前記ＩＣカードの各電極に接触する各コンタクトが組み込まれ、前記カード挿入通路に沿わせて前記コネクタハウジングの側部にハートカム式ロック機構が組み込まれ、前記ハートカム式ロック機構は前記カード挿入通路に前記ＩＣカードが挿入されたときにロックし、ロック状態の前記ＩＣカードに再度押し込み力が加わったときには前記ＩＣカードを前記カード挿入通路の手前側に戻す構造になっているＩＣカード用コネクタであって、
前記ハートカム式ロック機構は、前記ＩＣカードの挿入で後退し、前記ＩＣカードの排出時に手前側に戻るスライダーを備え、前記スライダーの手前側の部分に、前記カード挿入通路の対向する広面に直交する方向に弾性的に曲がる板バネが連設され、前記板バネの手前側の端部に操作子が固定され、前記操作子は前記カード挿入通路側に張り出して前記ＩＣカードを受けるカード受け部を備えていることを特徴とする。 According to the first aspect of the present invention, a card insertion path is provided by a facing wide surface and a facing clamping surface for inserting an IC card into the connector housing, and each electrode of the IC card is provided in the card insertion path. Each contact that comes into contact is incorporated, and a heart cam type locking mechanism is incorporated in a side portion of the connector housing along the card insertion path. The heart cam type locking mechanism is inserted when the IC card is inserted into the card insertion path. An IC card connector that is structured to return the IC card to the near side of the card insertion passage when a pressing force is applied again to the IC card in a locked state,
The heart cam type locking mechanism includes a slider that retracts upon insertion of the IC card and returns to the front side when the IC card is ejected, and is orthogonal to a wide surface facing the card insertion path at a portion on the front side of the slider. A leaf spring that elastically bends in a direction is provided continuously, and an operating element is fixed to an end portion on the front side of the leaf spring, and the operating element protrudes to the card insertion path side to receive a card receiving portion that receives the IC card. It is characterized by having.

本発明に係るＩＣカード用コネクタでは、コイルスプリングの蓄勢力でＩＣカードが外に出される際に、コネクタハウジングの外に放り出されるのを、カード挿入通路側に張り出している操作子のカード受け部で受けることにより防止するができる。   In the IC card connector according to the present invention, when the IC card is pulled out by the stored force of the coil spring, the card holder of the operating element protruding toward the card insertion passage is released from the connector housing. It can be prevented by receiving at the part.

ＩＣカードをカード挿入通路に挿入するには、操作子のカード受け部が邪魔になるが、板バネの曲がり易い性質を利用して操作子を押し下げ、一緒にカード受け部を下げ、この状態でＩＣカードを容易にカード挿入通路に挿入することができる。操作子の押し下げ力を除去すると、板バネの復元力で操作子とカード受け部とは、元の位置に戻る。   In order to insert the IC card into the card insertion path, the card receiving part of the operating element becomes an obstacle, but the operating part is pushed down by using the characteristic that the leaf spring is easily bent, and the card receiving part is lowered together. The IC card can be easily inserted into the card insertion path. When the pressing force of the operating element is removed, the operating element and the card receiving portion are returned to their original positions by the restoring force of the leaf spring.

以下、本発明に係るＩＣカード用コネクタを実施するための最良の形態を、図面を参照して詳細に説明する。ここで、図１は本発明に係るＩＣカード用コネクタを実施するための最良の形態を示す斜視図である。なお、前述した図３と図４と対応する部分には、同一符号を付けて示している。   The best mode for carrying out an IC card connector according to the present invention will be described below in detail with reference to the drawings. Here, FIG. 1 is a perspective view showing the best mode for carrying out the IC card connector according to the present invention. Note that portions corresponding to those in FIGS. 3 and 4 are denoted by the same reference numerals.

本例のＩＣカード用コネクタ１では、スライダー７の手前側の部分に、カード挿入通路３の対向する広面３ａに直交する方向に弾性的に曲がる板バネ１２が連設されている。この板バネ１２の手前側の端部に操作子１３が一体に固定されている。操作子１３は、カード挿入通路３側に張り出してＩＣカードＡを受けるカード受け部１３ａを備えている。   In the IC card connector 1 of this example, a leaf spring 12 that is elastically bent in a direction perpendicular to the wide surface 3 a facing the card insertion passage 3 is continuously provided on the front side of the slider 7. An operation element 13 is integrally fixed to the front end of the leaf spring 12. The operation element 13 includes a card receiving portion 13a that protrudes toward the card insertion passage 3 and receives the IC card A.

次に本例のＩＣカード用コネクタ１にＩＣカードの挿入方法を説明する。図２（Ａ）（Ｂ）は本例のＩＣカード用コネクタでコネクタハウジングの上部を外した状態の断面図であり、ＩＣカード挿入前の状態とＩＣカードが挿入された状態を示している。   Next, a method for inserting an IC card into the IC card connector 1 of this example will be described. 2A and 2B are cross-sectional views of the IC card connector of the present example with the upper portion of the connector housing removed, showing the state before the IC card is inserted and the state where the IC card is inserted.

ＩＣカードＡをカード挿入通路３に挿入するには、操作子１３のカード受け部１３ａが邪魔になるが、板バネ１２の曲がり易い性質を利用して操作子１３を押し下げ、一緒にカード受け部１３ａを下げ、この状態でＩＣカードＡを容易にカード挿入通路３に挿入することができる。操作子１３の押し下げ力を除去すると、板バネ１２の復元力で操作子１３とカード受け部１３ａとは、元の位置に戻り、図２（Ａ）に示す状態となる。このハートカム式ロック機構５では、ＩＣカードＡのカード挿入通路３に対する挿入時に、操作子１３を押し込むと、そのカード受け部１３ａでＩＣカードＡをカード挿入通路３に挿入することができる。   In order to insert the IC card A into the card insertion passage 3, the card receiving portion 13a of the operating element 13 becomes an obstacle, but the operating element 13 is pushed down by utilizing the property of the leaf spring 12 to be bent, and the card receiving section is together. 13a is lowered, and the IC card A can be easily inserted into the card insertion passage 3 in this state. When the pressing force of the operating element 13 is removed, the operating element 13 and the card receiving portion 13a are returned to their original positions by the restoring force of the leaf spring 12, and the state shown in FIG. In this heart cam type lock mechanism 5, when the operating element 13 is pushed in when the IC card A is inserted into the card insertion path 3, the IC card A can be inserted into the card insertion path 3 by the card receiving portion 13a.

このような構造のＩＣカード用コネクタ１では、コイルスプリング１０の蓄勢力でＩＣカードＡが外に出される際に、コネクタハウジング２の外に放り出されるのを、カード挿入通路３側に張り出している操作子１３のカード受け部１３ａで受けることにより防止するができる。   In the IC card connector 1 having such a structure, when the IC card A is ejected by the stored force of the coil spring 10, it is projected to the outside of the connector housing 2 so as to project to the card insertion passage 3 side. This can be prevented by being received by the card receiving portion 13a of the operating element 13 that is present.
