Description

【０００１】
【発明の属する技術分野】
本発明は、カードと接続するカードコネクタに関する。
【０００２】
【従来の技術】
この種のカードコネクタは、主に、携帯電話機、携帯情報端末（ＰＤＡ）、及びデジタルスチルカメラ（ＤＳＣ）等の携帯機器に実装され、ＩＣカード又は通信カード等のカードの接続に使用される。これらの携帯機器は、その特質から、取り扱い時に誤って落とすなどにより、衝撃力を受けることが多い。その衝撃力はカードを介してコネクタのコンタクトに伝わる。コンタクトは携帯機器の筐体や基板に半田付け接続されているので、衝撃量が全てその半田付け部にかかり、半田付け部を破壊することがある。
【０００３】
従来、ゴムなどの弾性体によりカード嵌合時の衝撃を和らげるようにしたコネクタがある（例えば、特許文献１参照）。
【０００４】
【特許文献１】
特開平６−２６０２３７号公報
【０００５】
【発明が解決しようとする課題】
しかしながら、特許文献１に記載されたコネクタは、コネクタ本体に追加部品であるゴムを貼り付けたり充填したりしなければならないため、コネクタ組立て時に余分な手間が必要となり、価格の上昇につながる。また、品質的にもゴムは温度の変化によりやわらかさが変わるため、常に一定の衝撃緩和力を維持できないといった欠点がある。
【０００６】
それ故に本発明の課題は、落下時などに衝撃を受けても破壊し難いカードコネクタを提供することにある。
【０００７】
【課題を解決するための手段】
本発明の一態様によれば、カードと接続するカードコネクタであって、前記カードの挿入を案内するフレーム部と、前記カードに接続するコンタクトを保持したベース部とからなり、前記フレーム部と前記ベース部とは互いに着脱自在に係合保持されるものであり、前記フレーム部は天板部と一対の側板部とを有し、前記側板部は前記カードの挿入を案内するガイド溝を有し、前記コンタクトは前記ベース部から前記一対の側板部間の中央部に突出し、前記天板部の一部を切り曲げることにより、前記ベース部及び前記側板部の近傍に突出する少なくとも１つの突起を設け、前記ガイド溝に案内され挿入された前記カードの側部の挿入側端面が前記突起に当接することで、前記コンタクトに接続された前記カードの挿入方向への移動が阻止されるようにしたことを特徴とするカードコネクタが得られる。
【０００９】
前記フレーム部は、取付対象物に固定される固定部を有してもよい。
【００１０】
本発明の他の態様によれば、上述したカードコネクタを実装したことを特徴とする携帯機器が得られる。
【００１１】
【発明の実施の形態】
図１を参照して、本発明の実施の形態に係るカードコネクタについて説明する。
【００１２】
図示のカードコネクタは、携帯電話機、携帯情報端末（ＰＤＡ）、及びデジタルスチルカメラ（ＤＳＣ）等の携帯機器に実装され、ＩＣカード又は通信カード等のカードの接続に使用されるものであり、フレーム部１とベース部２とからなる。通常、フレーム部１とベース部２は別々に携帯機器に実装される。携帯機器に実装された際に、ベース部２はフレーム部１の一端近傍部３に対向するように位置付けられる。フレーム部１の一端近傍部３にはナット４が固定されている。
【００１３】
フレーム部１は、携帯機器の筐体又はそれに固定された基板等の取付対象物と平行にのびる天板部５と、この天板部５の対向側縁から下方に向けて直角に曲がった両側板部６とを有している。天板部５の一端近傍部３に相当する部分には、ベース部２と同一側、即ち、下方に向けて突出する少なくとも一つ（ここでは二つ）の突起７が形成されている。また各側板部６には、カードの挿入を案内するために天板部５と平行にのびたガイド溝８と、携帯機器の筐体又は基板に固定される固定部９とが設けられている。
【００１４】
突起７は、図２に示すように、フレーム部１の天板部５の一部を切ってその内側部分を下方へほぼ直角に折り曲げることにより形成されたものである。ガイド溝８に案内されつつ挿入されたカード１０は、その挿入端を突起７に係止される。したがって、カード１０に加わる外力は突起７で受け止められる。
【００１５】
ベース部２は、カードに電気的に接続するための導電性の複数のコンタクト１１と、それらのコンタクト１１を配列させて保持した細長いインシュレータ１２とを有している。コンタクト１１は上述した取付対象物の回路パターンに半田付けされ、これによりベース部２を固定する。インシュレータ１２はその長手方向両端部にそれぞれフランジ部１３を有している。フランジ部１３には、ナット４に対向する部分に貫通穴１４が形成されている。貫通穴１４に挿通されたビス又はボルト（図示せず）をナット４にねじ込むことにより、フレーム部１とベース部２は互いに着脱自在に係合保持される。
【００１６】
カード（特に通信カード）はカードコネクタに挿入した状態で、筐体より出っ張っていることが多く、カードを挿入した状態で機器を誤って落下させると、落下時の衝撃力はカードを介してカードコネクタにかかる。
【００１７】
しかし、図１のカードコネクタは、フレーム部１に突起７が形成されているため、落下時の衝撃力の大部分をフレーム部１で受けることになり、したがって大きな強度が得られる。また仮にフレーム部１に破壊が生じたとしても、そのフレーム部１のみの交換で対処できるため、損害は少なくてすむ。
【００１８】
なお、上述では特定の実施の形態について説明したが、本発明はこれに限定されることはない。例えば、突起の数は３以上であってもよい。
【００１９】
【発明の効果】
以上説明したように、本発明によれば、落下時などに衝撃を受けても破壊し難いカードコネクタを提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a card connector connected to a card.
[0002]
[Prior art]
This type of card connector is mainly mounted on a portable device such as a mobile phone, a personal digital assistant (PDA), and a digital still camera (DSC), and is used to connect a card such as an IC card or a communication card. Due to the nature of these portable devices, they are often subjected to an impact force by being accidentally dropped during handling. The impact force is transmitted to the connector contact through the card. Since the contact is soldered and connected to the casing or substrate of the portable device, the entire impact amount is applied to the soldered portion, which may destroy the soldered portion.
[0003]
2. Description of the Related Art Conventionally, there is a connector in which an impact when a card is fitted is reduced by an elastic body such as rubber (for example, see Patent Document 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 6-260237
[Problems to be solved by the invention]
However, since the connector described in Patent Document 1 has to be attached or filled with rubber as an additional part to the connector body, extra labor is required when assembling the connector, leading to an increase in price. Also, in terms of quality, the softness of rubber changes with changes in temperature, so that there is a drawback that it is not always possible to maintain a constant impact relaxation force.
[0006]
Therefore, an object of the present invention is to provide a card connector that is difficult to be destroyed even if it is subjected to an impact when dropped.
[0007]
[Means for Solving the Problems]
According to one aspect of the present invention, there is provided a card connector connected to a card, comprising: a frame portion that guides insertion of the card; and a base portion that holds a contact connected to the card. The base part is detachably engaged and held, the frame part has a top plate part and a pair of side plate parts, and the side plate part has a guide groove for guiding insertion of the card. The contact protrudes from the base portion to a central portion between the pair of side plate portions, and at least one protrusion protruding in the vicinity of the base portion and the side plate portion is formed by cutting and bending a part of the top plate portion. provided, wherein by inserting side end surface of the side of being guided by the guide groove inserted the card abuts against the projection, movement of blocking in the insertion direction of the card connected to the contact Card connector is obtained is characterized in that as that.
[0009]
The said frame part may have a fixing | fixed part fixed to an attachment target object.
[0010]
According to another aspect of the present invention, a portable device in which the card connector described above is mounted is obtained.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
A card connector according to an embodiment of the present invention will be described with reference to FIG.
[0012]
The illustrated card connector is mounted on a portable device such as a mobile phone, a personal digital assistant (PDA), and a digital still camera (DSC), and is used to connect a card such as an IC card or a communication card. It consists of a part 1 and a base part 2. Usually, the frame unit 1 and the base unit 2 are separately mounted on a portable device. When mounted on a portable device, the base portion 2 is positioned so as to face the one-end vicinity portion 3 of the frame portion 1. A nut 4 is fixed to a portion 3 near one end of the frame portion 1.
[0013]
The frame portion 1 includes a top plate portion 5 extending in parallel with an attachment object such as a casing of a portable device or a substrate fixed thereto, and both sides bent at a right angle from the opposite side edge of the top plate portion 5 downward. And a plate portion 6. At a portion corresponding to the one-end vicinity portion 3 of the top plate portion 5, at least one (here, two) protrusions 7 are formed which protrude on the same side as the base portion 2, that is, downward. Each side plate portion 6 is provided with a guide groove 8 extending in parallel with the top plate portion 5 to guide card insertion and a fixing portion 9 fixed to the casing or substrate of the portable device.
[0014]
As shown in FIG. 2, the protrusion 7 is formed by cutting a part of the top plate part 5 of the frame part 1 and bending the inner part downward at a substantially right angle. The card 10 inserted while being guided by the guide groove 8 is locked to the protrusion 7 at its insertion end. Therefore, the external force applied to the card 10 is received by the protrusion 7.
[0015]
The base portion 2 has a plurality of conductive contacts 11 for electrical connection to the card, and an elongated insulator 12 that holds the contacts 11 in an array. The contact 11 is soldered to the circuit pattern of the attachment object described above, thereby fixing the base portion 2. The insulator 12 has flange portions 13 at both ends in the longitudinal direction. A through hole 14 is formed in the flange portion 13 at a portion facing the nut 4. By screwing a screw or bolt (not shown) inserted through the through hole 14 into the nut 4, the frame portion 1 and the base portion 2 are detachably engaged with each other.
[0016]
Cards (especially communication cards) are often protruding from the housing when inserted into the card connector, and if the device is accidentally dropped with the card inserted, the impact force at the time of dropping will drop through the card. Take the connector.
[0017]
However, in the card connector of FIG. 1, since the projection 7 is formed on the frame portion 1, the frame portion 1 receives most of the impact force at the time of dropping, and thus high strength is obtained. Further, even if the frame portion 1 is broken, it can be dealt with by replacing only the frame portion 1, so that the damage can be reduced.
[0018]
In addition, although specific embodiment was described above, this invention is not limited to this. For example, the number of protrusions may be 3 or more.
[0019]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a card connector that is difficult to be destroyed even if it is subjected to an impact when dropped.
