Description

本発明は、ICカードやフラッシュメモリーカード等のカードを携帯電話機やスマートフォン等の電子機器に搭載されたプリント配線基板に接続するための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 or a flash memory card to a printed wiring board mounted on an electronic device such as a mobile phone or a smartphone.

従来、携帯電話機やスマートフォン等の電子機器の外部記憶媒体としてICカードやフラッシュメモリーカード等のカードが使用されており、このカードと電子機器に搭載されたプリント配線基板とをカードコネクタを介して電気的に接続させている。   Conventionally, a card such as an IC card or a flash memory card has been used as an external storage medium of an electronic device such as a mobile phone or a smartphone, and this card and a printed wiring board mounted on the electronic device are electrically connected via a card connector. Connected.

この種のカードコネクタは、ICカード等のカードが挿入されるカード挿入部を有するハウジングと、カード挿入部の底部より突出させた弾性接触片を有する導電性金属板材からなる複数のコンタクトとを備え、カードをカード挿入部に挿入することで、カードの片面側に形成された信号伝達端子(パッド)が対応するコンタクトの弾性接触片と接触し、プリント配線基板とカードとを電気的に接続させるようになっている。   This type of card connector includes a housing having a card insertion portion into which a card such as an IC card is inserted, and a plurality of contacts made of a conductive metal plate having an elastic contact piece protruding from the bottom of the card insertion portion. By inserting the card into the card insertion portion, the signal transmission terminal (pad) formed on one side of the card comes into contact with the elastic contact piece of the corresponding contact, and electrically connects the printed wiring board and the card. It is like that.

また、この種のカードコネクタにおいては、ハウジングを絶縁合成樹脂製のモールド部材と、モールド部材の外側を覆う導電性金属材製のシールドカバーとを組み合せて構成し、シールドカバーによって電磁ノイズを遮蔽し、カード使用時にカードより生ずる電磁波がプリント配線基板に実装された他の電子部品に及ぼす影響を軽減するようにしたものが知られている(例えば、特許文献1を参照)。   Also, in this type of card connector, the housing is configured by combining an insulating synthetic resin mold member and a shield cover made of a conductive metal material that covers the outside of the mold member, and electromagnetic noise is shielded by the shield cover. In addition, there is known one that reduces the influence of electromagnetic waves generated from the card when the card is used on other electronic components mounted on a printed wiring board (for example, see Patent Document 1).

一方、この種のカードコネクタにおいては、シールドカバーの一部又は全部のカード挿抜方向の全長をカードの全長より短く形成し、カードをハウジングに挿入した状態においてカードの後端をカード挿入部の開口より突出させた状態に露出させ、その露出した部分を摘まむなりしてカードをハウジングより引き出せるようにした、所謂Push−Pull(プッシュ−プル)方式のものが知られている(例えば、特許文献2を参照)。   On the other hand, in this type of card connector, the total length in the card insertion / removal direction of a part or all of the shield cover is formed shorter than the total length of the card, and the rear end of the card is opened in the card insertion portion in a state where the card is inserted into the housing. A so-called Push-Pull type is known in which the card is pulled out from the housing by exposing the exposed portion to a more protruded state (see, for example, Patent Documents). 2).

このPush−Pull方式のカードコネクタでは、カードをカード挿入部の開口より突出させた状態に露出させ、その露出した部分を摘み代とし、その摘み代を摘まむなりしてハウジングよりカードを引き出せるようにしたことにより、特殊なカード取出し機構を備える必要が無く、その分、カードコネクタの小型化及び低廉化を図ることができるという利点があった。   In this Push-Pull card connector, the card is exposed in a state of protruding from the opening of the card insertion portion, the exposed portion is used as a picking allowance, and the picking allowance is picked so that the card can be pulled out from the housing. As a result, there is no need to provide a special card removal mechanism, and there is an advantage that the card connector can be reduced in size and cost accordingly.

しかしながら、上述の如き従来のカードコネクタでは、カードを挿抜するために常にカード挿入部の後端部を開口させた状態にしておかなくてはならず、その為、カードの後端面をシールドすることができなかった。   However, in the conventional card connector as described above, in order to insert and remove the card, the rear end portion of the card insertion portion must be kept open, and therefore the rear end surface of the card must be shielded. I could not.

また、従来のカードコネクタでは、カードの前端部分がカード挿入部前面開口より水平に突出した状態に露出している場合、カードの露出した部分より発せられる電磁波をシールドカバーによって完全に遮蔽することができず、その電磁波がプリント配線基板に実装された他の電子部品に影響を及ぼす虞があった。   Further, in the conventional card connector, when the front end portion of the card is exposed in a state of projecting horizontally from the front opening of the card insertion portion, the electromagnetic wave emitted from the exposed portion of the card can be completely shielded by the shield cover. The electromagnetic wave could not affect other electronic components mounted on the printed wiring board.

特に、上述した従来のPush-Pull方式のカードコネクタにおいては、カードを引き出すための摘み代を確保するため、ある程度カード後端部をカード挿入部の開口部より突出させた状態に露出させなければならず、その露出した部分(摘み代)から漏れる電磁波が問題となる虞があった。   In particular, in the conventional Push-Pull card connector described above, the rear end of the card must be exposed to a degree protruding from the opening of the card insertion portion in order to secure a handle for pulling out the card. In addition, electromagnetic waves leaking from the exposed portion (pinch allowance) may become a problem.

一方、従来のカードコネクタでは、適応する正規カードよりもサイズの小さな非正規カードが誤ってカード挿入部に挿入されてしまった場合、その非正規カード全体がシールドカバーに覆われてしまうため、カードを引き出すための摘み代が失われ、取り出すのが困難であるという問題もあった。   On the other hand, with a conventional card connector, if a non-genuine card smaller in size than the applicable regular card is accidentally inserted into the card insertion section, the entire non-genuine card will be covered with a shield cover. There is also a problem that it is difficult to take out the picking allowance for pulling out.

そこで、本発明は、このような従来の問題に鑑み、カードを引き出すための摘み代を確保しつつ、カード全体をシールド可能な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。   Therefore, in view of such a conventional problem, the present invention has been made for the purpose of providing a card connector capable of shielding the entire card while securing a handle for pulling out the card.

また、弾性接続片44の接点部44aが仮固定用孔58に嵌り込み、可動シールド部7がハーフロックされた状態となる。   Further, the contact portion 44a of the elastic connection piece 44 is fitted into the temporary fixing hole 58, and the movable shield portion 7 is half-locked.

また、カード挿入部2にカードAが挿入された状態においては、可動シールド部7をシールド位置とすることにより、可動後端板部によってカードAの抜け出し方向の移動が規制され、可動天板部50によってカードA後端側の浮き上がりが規制されるので、カードAに対するコンタクト4,4...の安定した接触状態が維持されるようになっている。   Further, in a state where the card A is inserted into the card insertion portion 2, by moving the movable shield portion 7 to the shield position, the movement of the card A in the withdrawal direction is restricted by the movable rear end plate portion, and the movable top plate portion. 50 prevents the rear end of the card A from rising, so that the stable contact state of the contacts 4, 4... With the card A is maintained.

尚、上述の実施例においては、可動シールド部7に回動アーム54,54を備え、回動アーム54,54を固定シールド部6に軸支させることにより前後方向に回動し、シールド位置とオープン位置との間で移動できるようにした例について説明したが、可動シールド部7の態様は、上記実施例に限定されず、例えば、固定天板部30と可動天板部50とに跨った蝶番を備え、当該蝶番を介して可動シールド部7が前後方向に回動できるようにしたものであってもよく、可動シールド部7を固定延出部40,40に枢支させ、横方向に回動するようにしたものであってもよい。   In the above-described embodiment, the movable shield part 7 is provided with the turning arms 54 and 54, and the turning arms 54 and 54 are pivotally supported by the fixed shield part 6 to rotate in the front-rear direction. Although the example which enabled it to move between open positions was demonstrated, the aspect of the movable shield part 7 is not limited to the said Example, For example, straddled the fixed top plate part 30 and the movable top plate part 50 A hinge may be provided so that the movable shield portion 7 can be rotated in the front-rear direction via the hinge. The movable shield portion 7 is pivotally supported by the fixed extension portions 40 and 40 and is laterally moved. It may be configured to rotate.
