Description

本発明は、ＩＣカード等のカードを基板に接続するためのカードコネクタであって、カードを簡単な操作で取り出すことのできる取り出し機能付きカードコネクタに関する。   The present invention relates to a card connector for connecting a card such as an IC card to a substrate, and relates to a card connector with a taking-out function that can take out the card by a simple operation.

従来、この種のカードコネクタにおいては、プッシュピンを操作することによりＩＣカード等のカード又はそのカードを収容したカードトレイ等のカード状部材をハウジング内より取り出すことができる取り出し機能付きのものが知られている（例えば、特許文献１）。   Conventionally, this type of card connector is known to have a take-out function that can take out a card-like member such as an IC card or a card tray containing the card from the housing by operating a push pin. (For example, Patent Document 1).

この取出し機能付きカードコネクタは、例えば、図６に示すように、ハウジング１００のカード挿抜方向奥側に回動可能に支持された押出アーム１０１を備え、プッシュピン１０２で押出しアーム１０１の一方の端部を押し込むことにより押出アーム１０１を回動させ、アームの他端側１０３でカードトレイ１０４の奥側縁を排出方向に押し出すようになっている。   For example, as shown in FIG. 6, this card connector with a taking-out function includes an extrusion arm 101 that is rotatably supported on the back side in the card insertion / removal direction of the housing 100, and one end of the extrusion arm 101 by a push pin 102. The pushing arm 101 is rotated by pushing the portion, and the other side 103 of the arm pushes the inner edge of the card tray 104 in the discharge direction.

特開平１０−１８９１３９号公報Japanese Patent Laid-Open No. 10-189139

しかしながら、上述の如き従来の技術では、押出しアーム及び押出アームを操作するためのプッシュピン等からなる取出し機構を有するため、コネクタ全体の外形、即ち、コネクタが取り付けられる基板に対する専有面積が大きくなり、それに伴い設計の自由度も低下するという問題があった。一方でコネクタの小型化を図るため押出しアームの外形を小さくすると、十分な押出し量をもってカード状部材を排出するのに必要なアームの長さが確保できないという問題があった。   However, in the conventional technology as described above, since it has a take-out mechanism consisting of an extrusion arm and a push pin for operating the extrusion arm, the entire outer shape of the connector, that is, the area occupied by the board to which the connector is attached increases. Along with that, there was a problem that the degree of freedom of design also decreased. On the other hand, if the outer shape of the pushing arm is reduced in order to reduce the size of the connector, there is a problem that the arm length necessary for discharging the card-like member with a sufficient pushing amount cannot be secured.

また、カード状部材を押し出す際、操作者の加えた力がプッシュピンを介して押出しアームに伝わるため、操作者が力を入れすぎるとカード状部材が勢いよく飛び出してしまい、カード等の破損を招く虞があるという問題があった。更に、落下等による衝撃によってもトレイ等のカード状部材が抜け出てしまう虞があるという問題があった。
更にまた、取出し機構を有するためにこの種のコネクタでは、部品点数が多くなり、その分コストが嵩むという問題がある。 Also, when pushing out the card-like member, the force applied by the operator is transmitted to the pushing arm via the push pin, so if the operator puts too much force, the card-like member will pop out vigorously and damage the card etc. There was a problem that there was a risk of inviting. Furthermore, there is a problem that a card-like member such as a tray may come out due to an impact caused by dropping or the like.
Furthermore, since this type of connector has a take-out mechanism, there is a problem that the number of parts increases and the cost increases accordingly.

本発明は、このような従来の問題に鑑み、安定したカード取出し操作を行くことができるとともに小型化を可能とし、且つ安価に製造が可能な取出し機能付きカードコネクタの提供を目的としてなされたものである。   SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has been made with the object of providing a card connector with a take-out function that enables stable card take-out operations, enables downsizing, and can be manufactured at low cost.
