Description

本発明は、電子機器、情報端末機器等に取り付けられるカードコネクタに係り、特に携帯機器に使用され微小化するＳＤカード、ＳＩＭカード等のＩＣカードに対応した小型化が容易なカードコネクタに関する。   The present invention relates to a card connector attached to an electronic device, an information terminal device, and the like, and more particularly to a card connector that can be easily miniaturized and is compatible with an IC card such as an SD card or a SIM card that is used in portable devices and is miniaturized.

近年、パソコン、カメラ、録音機、携帯電話、携帯型オーディオ、ＰＤＡ（Personal Digital Assistance）等の電子機器や情報端末機器等において、情報の記録、伝達あるいは処理に用いられるＩＣチップと呼ばれるＩＣ部品が組込まれたＰＣカード、ＳＤカード、ＳＩＭカード（各商品名）等のＩＣカードの利用が増大してきている。通常、これ等のＩＣカードは上記機器に取り付けられたカードコネクタに装着され使用される。そして、高機能化あるいは多機能化と共にその小型化が進む携帯機器にあって、特にＳＤカードやＳＩＭカード等の小型のメモリカードが装着されるカードコネクタの小型化が広く求められている。   In recent years, in electronic devices such as personal computers, cameras, recorders, mobile phones, portable audio devices, PDAs (Personal Digital Assistance) and information terminal devices, IC components called IC chips used for recording, transmitting or processing information have been developed. The use of IC cards such as PC cards, SD cards, and SIM cards (each product name) incorporated is increasing. Usually, these IC cards are used by being attached to a card connector attached to the device. In portable devices that are becoming more and more miniaturized with higher functionality or multi-function, there is a wide demand for miniaturization of a card connector to which a small memory card such as an SD card or a SIM card is mounted.

このようなカードコネクタは、通常、カードの挿抜のためのカード受口、カードを収容しカードに内蔵された例えばＩＣと電気接続するコンタクトが設けられたコネクタハウジングを有する。ここで、ＩＣカードの装着における利便性および安全性から、カードのコネクタハウジング内への挿入／ロック、およびコネクタハウジングからの排出（イジェクト）をカードの後端部の押圧のみで行えるようにした、いわゆるプッシュイン・プッシュアウト機構を備えたカードコネクタが主流になってきている（例えば、特許文献１，２参照）。   Such a card connector usually has a card housing for inserting / removing the card, and a connector housing provided with contacts for accommodating the card and electrically connecting with, for example, an IC built in the card. Here, for convenience and safety in mounting the IC card, insertion / locking of the card into the connector housing and ejection from the connector housing (eject) can be performed only by pressing the rear end of the card. Card connectors having so-called push-in / push-out mechanisms have become mainstream (see, for example, Patent Documents 1 and 2).

このプッシュイン・プッシュアウト機構を有する従来のカードコネクタの一例について図８ないし図１０を参照しその主要部を説明する。図８は従来におけるカードコネクタの外観斜視図であり、図９はカードコネクタのカバー部材である上ハウジング部材を取り外し、その本体である下ハウジング部材とカードプッシュ部材を分解して示した斜視図である。図１０は、カードコネクタのプッシュイン・プッシュアウト機構においてカードのロック、イジェクトに用いられるカム要素の一例を示し、（ａ）はカム要素の概略平面図、（ｂ）はハート形カムの周りのカム溝の段差図である。   An example of a conventional card connector having this push-in / push-out mechanism will be described with reference to FIGS. FIG. 8 is an external perspective view of a conventional card connector, and FIG. 9 is an exploded perspective view of an upper housing member that is a cover member of the card connector, and an exploded view of the lower housing member and the card push member that are the main body. is there. FIG. 10 shows an example of a cam element used for locking and ejecting a card in the push-in / push-out mechanism of the card connector, (a) is a schematic plan view of the cam element, and (b) is a view around the heart-shaped cam. It is a level | step difference figure of a cam groove.

図８，９に示すように、従来におけるカードコネクタは、コネクタ本体である下ハウジング部材１０１、この下ハウジング部材１０１と組合されてコネクタハウジングを形成するカバー部材の上ハウジング部材１０２、カードコネクタのプッシュイン・プッシュアウト機構１０３、カードの電極部と電気接続する複数個のコンタクト１０４を有している。ここで、下ハウジング部材１０１は、適宜な合成樹脂材料などの絶縁材料によって成形して作られ、金属板材料の上ハウジング部材１０２と組合され中空の偏平なカード収容スペースを形成する。そして、カード受口１０５が上記カード収容スペースに対するカード２００の挿抜口として作られている。   As shown in FIGS. 8 and 9, a conventional card connector includes a lower housing member 101 which is a connector body, an upper housing member 102 of a cover member which is combined with the lower housing member 101 to form a connector housing, and a card connector push. An in-push-out mechanism 103 and a plurality of contacts 104 that are electrically connected to the electrode portions of the card are provided. Here, the lower housing member 101 is made of an appropriate insulating material such as a synthetic resin material, and is combined with the upper housing member 102 of a metal plate material to form a hollow flat card receiving space. A card slot 105 is formed as an insertion / extraction slot for the card 200 with respect to the card accommodation space.

このようなカードコネクタにおいて、コンタクト１０４では、その複数の端子部１０４ａがカードコネクタの取り付けられた機器の回路基板の配線にハンダ接合される。そして、上記端子部１０４のカード挿入方向に延在した弾性接片から成る複数の接点部１０４ｂが、カード２００の裏面に配置した電極部である複数の電極パッド（不図示）に加圧接触するようになっている。   In such a card connector, at the contact 104, the plurality of terminal portions 104a are soldered to the wiring of the circuit board of the device to which the card connector is attached. A plurality of contact portions 104b made of elastic contact pieces extending in the card insertion direction of the terminal portion 104 are in pressure contact with a plurality of electrode pads (not shown) that are electrode portions arranged on the back surface of the card 200. It is like that.

そして、図９に示すように、プッシュイン・プッシュアウト機構１０３は、下ハウジング部材１０１の一方の側の縁辺に沿って滑動可能に装着されたカードプッシュ部材１０６、その前端部に取り付けられたカード係合部１０７、カードプッシュ部材１０６を弾性付勢するバネ部材１０８を備えている。更に、プッシュイン・プッシュアウト機構１０３は、下ハウジング部材１０１の側縁の下板部に形成したカム要素１０９、カム要素１０９に滑合する揺動アーム１１０を有している。
ここで、カードプッシュ部材１０６は、バネ部材１０８、そしてカム要素１０９により適正に案内されカード挿抜方向に直線往復動できるようになっている。 As shown in FIG. 9, the push-in / push-out mechanism 103 includes a card push member 106 slidably mounted along one side edge of the lower housing member 101, and a card attached to the front end portion thereof. A spring member 108 that elastically biases the engaging portion 107 and the card push member 106 is provided. Further, the push-in / push-out mechanism 103 has a cam element 109 formed on the lower plate portion of the side edge of the lower housing member 101, and a swing arm 110 that slides on the cam element 109.
Here, the card push member 106 is properly guided by the spring member 108 and the cam element 109 so as to be able to reciprocate linearly in the card insertion / removal direction.

カード２００のプッシュインでは、カード２００は、カード２００の後端部の押圧により、バネ部材１０８の弾発に抗してカード受口１０５から挿入される。この挿入では、カード２００の前端のコーナー部に設けられたカード挿入姿勢指示用斜面（受圧斜面）２００ａがカード係合部１０７の加圧斜面１０７ａを押圧する。そして、カードプッシュ部材１０６は、カード係合部１０７の前端面１０７ｂが下ハウジング部材１０１の前壁に達するまで、バネ部材１０８の弾発力に抗してカード２００の挿入方向に移動する。ここで、このバネ部材１０８は、その一端がカードプッシュ部材１０６の前端に取り付けられ、その他端が下ハウジング部材１０１の前壁から突出したバネ受け突起１１１に外挿されてその位置決めがなされている。   In push-in of the card 200, the card 200 is inserted from the card receiving port 105 against the impact of the spring member 108 by pressing the rear end of the card 200. In this insertion, a card insertion posture instruction inclined surface (pressure receiving inclined surface) 200 a provided at a corner portion at the front end of the card 200 presses the pressure inclined surface 107 a of the card engaging portion 107. Then, the card push member 106 moves in the insertion direction of the card 200 against the elastic force of the spring member 108 until the front end face 107b of the card engaging portion 107 reaches the front wall of the lower housing member 101. Here, one end of the spring member 108 is attached to the front end of the card push member 106, and the other end is externally inserted into the spring receiving projection 111 protruding from the front wall of the lower housing member 101, and the spring member 108 is positioned. .

一方、カード２００のプッシュアウトでは、カード２００の後端部の再押圧により、今度はカードプッシュ部材１０６がバネ部材１０８にてカード２００の排出方向に弾発され移動する。そして、カードプッシュ部材１０６の後端面がストッパー１１２に達するまで排出方向に移動する。   On the other hand, in the push-out of the card 200, the card push member 106 is repelled and moved in the ejecting direction of the card 200 by the spring member 108 by re-pressing the rear end portion of the card 200. Then, the card push member 106 moves in the discharge direction until the rear end surface reaches the stopper 112.

上記カードプッシュ部材１０６の挿入方向あるいは排出方向の移動の切り替えは、カム要素１０９の案内構造によりなされる。ここで、上記揺動アーム１１０は、カードプッシュ部材１０６の後端側にその基端が回動可に支承され、その自由端がカム要素１０９のカム溝に係合している。この揺動アーム１１０がカードプッシュ部材１０６を案内し、その挿入方向あるいは排出方向の移動の切り替え、そしてカードプッシュ部材１０６の後述される錠止等を行う。   Switching of the insertion direction or the ejection direction of the card push member 106 is performed by a guide structure of the cam element 109. Here, the swing arm 110 has a base end rotatably supported on the rear end side of the card push member 106 and a free end engaged with a cam groove of the cam element 109. The swing arm 110 guides the card push member 106, switches the movement in the insertion direction or the ejection direction, and locks the card push member 106, which will be described later.

このカム要素１０９の構造とその動作について図１０を参照して説明する。カム要素１０９はハート形カム１１３の周りに掘られたカム溝１１４を有する。そして、揺動アーム１１０の自由端１１０ａがカム溝１１４と滑合している。カード２００のプッシュインでは、図１０（ａ）の矢印で示すように、上記自由端１１０ａが、直線状ガイド溝１１５から下ガイド溝１１６、一定の傾斜角度の第１の傾斜面１１７を通り溝凸所１１８に上る。そして、この自由端１１０ａは、その後に第１の段差Ａを垂直降下してカードロック作動開始用ガイド溝１１９に進む。この一連の動きに案内されて、カードプッシュ部材１０６がカード２００を挿入状態にする。   The structure and operation of the cam element 109 will be described with reference to FIG. The cam element 109 has a cam groove 114 dug around the heart-shaped cam 113. The free end 110 a of the swing arm 110 is in sliding contact with the cam groove 114. In the push-in of the card 200, as shown by the arrow in FIG. 10A, the free end 110a passes through the linear guide groove 115, the lower guide groove 116, the first inclined surface 117 having a fixed inclination angle, and the groove. Go up to the convex 118. Then, the free end 110a vertically descends the first step A and proceeds to the card lock operation start guide groove 119. Guided by this series of movements, the card push member 106 puts the card 200 into an inserted state.

更に、自由端１１０ａは、第２の段差Ｂを垂直降下してハートカム係合用凹所１２０においてハートカム係止部１１３ａで係止されこの位置で安定して固持される。このようにして揺動アーム１１０が係止されカードプッシュ部材１０６が錠止される。この状態でカード２００がロック状態になり、下ハウジング部材１０１に取り付けられたコンタクト１０４にカード２００の電極パッドが安定的に接続し、カード２００がカードコネクタに装着される。   Further, the free end 110a vertically descends the second step B and is locked by the heart cam engagement portion 113a in the heart cam engagement recess 120 and is stably held at this position. In this way, the swing arm 110 is locked and the card push member 106 is locked. In this state, the card 200 is locked, the electrode pads of the card 200 are stably connected to the contacts 104 attached to the lower housing member 101, and the card 200 is attached to the card connector.

そして、カード２００のプッシュアウトでは、自由端１１０ａはハートカム係合用凹所１２０のハートカム係止部１１３ａから離脱し、第３の段差Ｃを垂直降下して、カム溝１１４における最深部のカードイジェクト作動開始用ガイド溝１２１に進む。そして、カードプッシュ部材１０６の錠止が解除される。以後は、自由端１１０ａはバネ部材１０８の弾発に従って第２の傾斜面１２２を通り上ガイド溝１２３に上り、更に第４の段差Ｄを垂直降下して下ガイド溝１１６から元の直線状ガイド溝１１５に戻る。この一連の動きによりカードプッシュ部材１０６がカード２００をイジェクトさせることになる。   When the card 200 is pushed out, the free end 110a is disengaged from the heart cam engaging portion 113a of the heart cam engaging recess 120, vertically descends the third step C, and the card ejecting operation at the deepest portion in the cam groove 114 is performed. Proceed to the starting guide groove 121. Then, the lock of the card push member 106 is released. Thereafter, the free end 110a passes through the second inclined surface 122 and rises to the upper guide groove 123 according to the elasticity of the spring member 108, and further descends the fourth step D vertically from the lower guide groove 116 to the original linear guide. Return to groove 115. The card push member 106 ejects the card 200 by this series of movements.

上述したように、従来のカム要素１０９では、ハート形カム１１３の周囲に形成されるカム溝１１４の底面は、カードプッシュ部材１０６がカード挿抜方向に適正に直線往復動できるように、第１の段差Ａ〜第４の段差Ｄを備えている。この４個の段差により、カム溝１１４に滑合している自由端１１０ａは、カム溝１１４を逆行すること無くそれに沿って一定方向に摺動し、カードプッシュ部材１０６を上述したように適正に案内するようになっている。このため、従来のカム要素１０９では、図１０（ｂ）に示しているように、カム溝１１４における溝凸所１１８からその最深部であるカードイジェクト作動開始用ガイド溝１２１まで、少なくとも第１の段差Ａ〜第３の段差Ｃによって形成されるカム溝１１４底面の位置高低差が必須になっている。
特開２０００−２５１０２５号公報 特開２００４−９５４４９号公報 As described above, in the conventional cam element 109, the bottom surface of the cam groove 114 formed around the heart-shaped cam 113 has a first linear reciprocating motion so that the card push member 106 can be properly linearly reciprocated in the card insertion / removal direction. A level difference A to a fourth level difference D are provided. Due to these four steps, the free end 110a sliding on the cam groove 114 slides in a certain direction along the cam groove 114 without going backward, and the card push member 106 is properly moved as described above. It is designed to guide you. For this reason, in the conventional cam element 109, as shown in FIG. 10B, at least the first portion from the groove convex portion 118 in the cam groove 114 to the card ejection operation start guide groove 121 which is the deepest portion thereof. The position height difference of the bottom surface of the cam groove 114 formed by the step A to the third step C is essential.

しかしながら、このような従来のプッシュイン・プッシュアウト機構を有するカードコネクタにおいては、上述したように、プッシュイン・プッシュアウト機構を構成するカム要素のカム溝底面が少なくとも３段から成る位置高低差を必要とし、この位置高低差がカム要素の薄型化あるいは低背化を制約するようになる。そして、例えばminiＳＤカード、microＳＤカード（各商品名）といわれる微小化したＳＤカードやＳＩＭカード等のように、その肉厚が１ｍｍ以下になりその平面寸法が１０ｍｍ〜１５ｍｍ程度以下に微小化してくると、上記カム要素の薄型化の制約からカードコネクタの低背化およびその小型化の限界が顕在化するという大きな問題があった。   However, in the card connector having such a conventional push-in / push-out mechanism, as described above, the cam groove bottom surface of the cam element constituting the push-in / push-out mechanism has a difference in position height consisting of at least three steps. This difference in position height restricts the reduction in thickness or height of the cam element. And, for example, miniaturized SD card or microSD card (each trade name) called miniaturized SD card, SIM card, etc., its thickness becomes 1 mm or less and its planar dimension becomes 10 mm to 15 mm or less. And there was a big problem that the limitation of the low profile and the miniaturization of the card connector becomes obvious due to the limitation of the thinning of the cam element.

本発明は、上述の事情に鑑みてなされたものであり、その低背化が容易になる新規なカム要素を実現させ、従来に増して低背化および小型化するカードコネクタを提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and provides a card connector that realizes a novel cam element that can be easily reduced in height, and is reduced in height and size as compared with the conventional one. Objective.

上記目的を達成するために、本発明にかかるカードコネクタは、下ハウジング部材と上ハウジング部材とによってハウジング形状のカード収容スペースが形成され、押圧によりカードを前記カード収容スペースに挿入してロックし、更にその再押圧により前記カードを前記カード収容スペースから排出してイジェクトするプッシュイン・プッシュアウト機構が設けられたカードコネクタにおいて、前記プッシュイン・プッシュアウト機構は、前記カードの挿入方向および排出方向に往復運動するカードプッシュ部材、該カードプッシュ部材を弾性付勢するバネ部材、前記カードプッシュ部材の往復運動を案内するカム要素を備え、前記カム要素は、ハート形カムおよび該ハートカムの周りにループ状に設けられたカム溝により形成され、該カム溝の底面は、深い面、傾斜面、浅い面およびステップ状の段部がこの順に繰り返して形成され、前記カードプッシュ部材の往復運動の案内は、前記カム溝底面の前記深い面、傾斜面、浅い面およびステップ状の段部をこれ等の順に一方向に摺動する揺動アームによって行われる、という構成になっている。   To achieve the above object, the card connector according to the present invention has a housing-shaped card storage space formed by the lower housing member and the upper housing member, and the card is inserted into the card storage space by pressing and locked.

In these drawings, reference numerals are given to the main parts, and the same or similar parts are the same reference numerals.

図１ないし図３に示されるように、本実施形態のカードコネクタ１０は、コネクタ本体としての下ハウジング部材１１と、この下ハウジング部材１１と組合されるカバー部材としての上ハウジング部材１２とにより中空で扁平なカード収容スペース１３を有するハウジング形状に構成されている。ここで、下ハウジング部材１１は加工性に優れた絶縁性の合成樹脂材料の成形により作られ、上ハウジング部材１２は例えばステンレス等の金属板材料または絶縁性の合成樹脂材料により作られる。上ハウジング部材１２は金属板材料で作る方が薄型化、強度、打ち抜き曲げ加工などの加工性において好適である。   As shown in FIGS. 1 to 3, the card connector 10 according to the present embodiment is hollow by a lower housing member 11 as a connector body and an upper housing member 12 as a cover member combined with the lower housing member 11. The housing has a flat card receiving space 13. Here, the lower housing member 11 is made by molding an insulating synthetic resin material excellent in workability, and the upper housing member 12 is made of a metal plate material such as stainless steel or an insulating synthetic resin material. The upper housing member 12 is preferably made of a metal plate material in view of thinness, strength, workability such as punching and bending.

そして、上記ハウジングの後端部にカード受口１４が上記カード収容スペース１３に対するカード挿抜口として作られている。更に、下ハウジング部材１１にはカードの電極パッドと加圧接触するための多数のコンタクト１５が植設されている。このコンタクト１５は、その複数の端子部１５ａがカード受口１４の領域に形成され、機器の回路基板の配線にハンダ接合されるようになっている。なお、複数の端子部１５ａは、カード受口１４の領域に形成されることとは限らず、ハウジングの前端部に形成されても良い。また、端子部１５ａからカード挿抜方向に伸びる弾性接片から成る複数の接点部１５ｂがカード収容スペース１３内に形成され、その弾性変位によりカードの電極パッドと加圧接触する。   A card slot 14 is formed at the rear end of the housing as a card insertion / extraction slot for the card accommodation space 13. The lower housing member 11 is provided with a large number of contacts 15 for making pressure contact with the electrode pads of the card. The contact 15 has a plurality of terminal portions 15a formed in the area of the card slot 14 and is soldered to the wiring of the circuit board of the device. Note that the plurality of terminal portions 15a are not necessarily formed in the area of the card slot 14, but may be formed at the front end portion of the housing. Further, a plurality of contact portions 15b made of elastic contact pieces extending from the terminal portion 15a in the card insertion / removal direction are formed in the card housing space 13, and are brought into pressure contact with the electrode pads of the card by the elastic displacement.

また、図２，３に示すようなプッシュイン・プッシュアウト機構１６が下ハウジング部材１１の一側縁に設けられている。このプッシュイン・プッシュアウト機構１６は、下ハウジング部材１１の側縁辺に沿いカード挿抜方向に進退動可に配置されたスライダーとしてのカードプッシュ部材１７、該カードプッシュ部材１７を弾性付勢するバネ部材１８を備えている。ここで、カードプッシュ部材１７は、例えば加工性に優れた液晶ポリマーのような合成樹脂から成る。そして、その下部領域にカード挿抜方向に延在するスライドガイド（不図示）が設けられ、ガイドスロット１９と滑合してカードプッシュ部材１７がスライダーとして直線往復運動できるようになっている。また、その中央領域に、カード挿抜方向に対し例えば一定角度に傾斜した加圧斜面１７ａが形成されている。   A push-in / push-out mechanism 16 as shown in FIGS. 2 and 3 is provided on one side edge of the lower housing member 11. The push-in / push-out mechanism 16 includes a card push member 17 serving as a slider that can be moved back and forth in the card insertion / removal direction along the side edge of the lower housing member 11, and a spring member that elastically biases the card push member 17. 18 is provided. Here, the card push member 17 is made of a synthetic resin such as a liquid crystal polymer having excellent processability. A slide guide (not shown) extending in the card insertion / removal direction is provided in the lower area, and the card push member 17 can be linearly reciprocated as a slider by sliding with the guide slot 19. In addition, a pressurizing slope 17a is formed in the central region, for example, inclined at a certain angle with respect to the card insertion / removal direction.

更に、プッシュイン・プッシュアウト機構１６は、下ハウジング部材１１の側縁の下板部に形成したカム要素２０、該カム要素２０に係合する揺動アーム２１を有している。ここで、カム要素２０の形成される下板部は例えば加工性に優れる液晶ポリマーのような合成樹脂から成る。また、揺動アーム２１はステンレス等の金属製が強度的に好ましく、その基端がカードプッシュ部材１７の前端領域に形成された孔１７ｂに回動可に支承され、その自由端がカム要素２０のカム溝に滑合されている。そして、カードプッシュ部材１７は、バネ部材１８とカム要素２０により適正にカード挿抜方向に直線往復動できるようになっている。   Further, the push-in / push-out mechanism 16 includes a cam element 20 formed on the lower plate portion of the side edge of the lower housing member 11 and a swing arm 21 that engages with the cam element 20. Here, the lower plate portion on which the cam element 20 is formed is made of a synthetic resin such as a liquid crystal polymer having excellent processability. The swing arm 21 is preferably made of metal such as stainless steel, and its base end is rotatably supported in a hole 17b formed in the front end region of the card push member 17, and its free end is the cam element 20. It is fitted in the cam groove. The card push member 17 can be linearly reciprocated in the card insertion / removal direction appropriately by the spring member 18 and the cam element 20.

カードのカードコネクタ１０への挿入すなわちプッシュインでは、例えばmicroＳＤカードは、その後端部の押圧により、コイルスプリングのような圧縮バネを有するバネ部材１８の弾発に抗してカード受口１４から挿入される。この挿入においては、カードの前端のコーナー部に設けられたカード挿入姿勢指示用斜面である受圧斜面がカードプッシュ部材１７の加圧斜面１７ａを押圧する。なお、カードが誤って後端から方向から挿入された場合、カードの後端部分が加圧斜面１７ａに当接することとなる。このためカードの後端がコンタクトに接触する位置まで挿入されることを防ぐことができる。そして、カードプッシュ部材１７は、その前端面１７ｃが下ハウジング部材１１の隔壁縁端２２に達するまでカードの挿入方向に移動する。上記バネ部材１８は、その一端がカードプッシュ部材１７の後端に取り付けられ、その他端が下ハウジング部材１１の側縁から突出したバネ受け突起２３に外挿されてその位置決めがなされている。   When the card is inserted into the card connector 10, that is, push-in is performed, for example, a microSD card is inserted from the card receiving opening 14 against the impact of the spring member 18 having a compression spring such as a coil spring by pressing the rear end portion. Is done. In this insertion, a pressure receiving inclined surface, which is a card insertion posture indicating inclined surface provided at a corner portion at the front end of the card, presses the pressure inclined surface 17 a of the card push member 17. If the card is mistakenly inserted from the rear end, the rear end portion of the card comes into contact with the pressure inclined surface 17a. For this reason, it is possible to prevent the rear end of the card from being inserted to a position where it contacts the contact. The card push member 17 moves in the card insertion direction until the front end surface 17c reaches the partition wall edge 22 of the lower housing member 11. One end of the spring member 18 is attached to the rear end of the card push member 17, and the other end is externally inserted into a spring receiving projection 23 protruding from the side edge of the lower housing member 11 to be positioned.

そして、カードのカードコネクタ１０からの排出すなわちプッシュアウトでは、カード後端の再押圧により、カードプッシュ部材１７がバネ部材１８にてカードの排出方向に弾発され移動する。そして、カードプッシュ部材１７の後端面がストッパー２４に達するまで排出方向に移動する。   When the card is ejected from the card connector 10, that is, when the card is pushed out, the card push member 17 is ejected and moved in the card ejection direction by the spring member 18 by re-pressing the rear end of the card. Then, the card push member 17 moves in the discharge direction until the rear end surface of the card push member 17 reaches the stopper 24.

ここで、カードプッシュ部材１７の挿入方向あるいは排出方向の移動の切り替えは、本実施形態の特徴的技術事項であるカム要素２０案内によってなされる。このカム要素２０の構造をその基本動作と共に図４を参照して説明する。図４は、カードコネクタ１０のプッシュイン・プッシュアウト機構１６においてカードのロック、イジェクトに用いられるカム要素の一例を示し、（ａ）はカム要素の概略平面図、（ｂ）はハート形カム周りのカム溝の段差図である。   Here, switching of the movement of the card push member 17 in the insertion direction or the discharge direction is performed by the cam element 20 guide which is a characteristic technical matter of the present embodiment. The structure of the cam element 20 will be described with reference to FIG. 4 together with its basic operation. FIG. 4 shows an example of a cam element used for locking and ejecting a card in the push-in / push-out mechanism 16 of the card connector 10, (a) is a schematic plan view of the cam element, and (b) is around the heart-shaped cam. It is a level | step difference figure of a cam groove.

下ハウジング部材１１の下板部に設けられたカム要素２０はハート形カム２５が突出するようにその周りに掘られたカム溝２６を有し、上述したように揺動アーム２１の自由端２１ａがカム溝２６と滑合し、自由端２１ａがカム溝２６内を滑らかに摺動する。また、揺動アーム２１は、図１に示す上ハウジング部材１２の天板部の所定箇所に設けられたアーム押え１２ａにより押圧され、その自由端２１ａがカム溝２６内から離脱することはない。このアーム押え１２ａは弾力性を備えたステンレス等の金属条片になっている。   The cam element 20 provided in the lower plate portion of the lower housing member 11 has a cam groove 26 that is dug around the heart-shaped cam 25 so that the heart-shaped cam 25 protrudes. As described above, the free end 21a of the swing arm 21 is provided. Slides into the cam groove 26, and the free end 21a slides smoothly in the cam groove 26. Further, the swing arm 21 is pressed by an arm presser 12 a provided at a predetermined position of the top plate portion of the upper housing member 12 shown in FIG. 1, and the free end 21 a is not detached from the cam groove 26. The arm presser 12a is a metal strip such as stainless steel having elasticity.

カードのプッシュインでは、揺動アーム２１の自由端２１ａは、カム溝２６底面の一部を構成し深い面に相当する待機状態になる直線状ガイド溝２７から、カム溝２６底面を構成している一定の傾斜角度の第１の傾斜面２８を通り、その浅い面となる第１の凸所２９に上る。その後、この自由端２１ａは、一段の垂直降下部２９ａを経て深い面となる第１の凹所３０に進む。この第１の凹所３０が従来の技術で説明したカードロック作動開始用ガイド溝１１９に相当している。この一連の動きが従来技術で説明したカードの挿入状態に対応する。   In the card push-in, the free end 21a of the swing arm 21 forms a bottom surface of the cam groove 26 from a linear guide groove 27 that forms a part of the bottom surface of the cam groove 26 and is in a standby state corresponding to a deep surface. The first inclined surface 28 having a certain inclination angle passes through the first convex portion 29 which is a shallow surface. Thereafter, the free end 21a proceeds to the first recess 30 that becomes a deep surface through the one-step vertical descent portion 29a. The first recess 30 corresponds to the card lock operation start guide groove 119 described in the prior art. This series of movements corresponds to the card insertion state described in the prior art.

次に、自由端２１ａは、第２の傾斜面３１を通り浅い面となる第２の凸所３２に上る。そして、同じ一段の垂直降下部３２ａを経て深い面となる第２の凹所３３に進む。この第２の凹所３３が従来のハートカム係合用凹所１２０に相当する。揺動アーム２１はハート形カムの窪み部であるハートカム係止部２５ａで係止され、この第２の凹所３３における位置で安定して固持される。このようにして揺動アーム２１が係止されカードプッシュ部材１７が錠止される。この状態がカードのロック状態であり、下ハウジング部材１１に取り付けられたコンタクト１５にカードの電極パッドが安定的に接続し、カードがカードコネクタ１０に装着される。   Next, the free end 21 a passes through the second inclined surface 31 and goes up to the second convex portion 32 that becomes a shallow surface. And it progresses to the 2nd recessed part 33 used as the deep surface through the same 1 step | paragraph vertical descent | fall part 32a. The second recess 33 corresponds to the conventional heart cam engagement recess 120. The swing arm 21 is locked by a heart cam locking portion 25a that is a hollow portion of the heart-shaped cam, and is stably held at a position in the second recess 33. In this way, the swing arm 21 is locked and the card push member 17 is locked. This state is a locked state of the card, and the electrode pad of the card is stably connected to the contact 15 attached to the lower housing member 11, and the card is attached to the card connector 10.

そして、カードのプッシュアウトでは、自由端２１ａは第２の凹所３３のハートカム係止部２５ａによる係止から離脱し、第３の傾斜面３４を通り浅い面となる第３の凸所３５に上る。その後に、同じ一段の垂直降下部３５ａを経て深い面となる第３の凹所３６に進む。この第３の凹所３６が従来の技術のカードイジェクト作動開始用ガイド溝１２１に相当する。この第３の凹所３６においてカードプッシュ部材１７の錠止が完全に解除される。そして、以後は、自由端２１ａはバネ部材１８の弾発に従い、第４の傾斜面３７を通り浅い面となる第４の凸所３８に上り、その後に、同じ一段の垂直降下部３８ａを経て元の待機状態となる直線状ガイド溝２７に戻る。この一連の動きによりカードプッシュ部材１７がカードをイジェクト作動させる。
一連の傾斜面２８，３１，３４，３７は揺動アーム２１の自由端２１ａの進行方向に対して上り傾斜面を形成し、一連の垂直降下部２９ａ，３２ａ，３５ａ，３８ａは自由端２１ａの逆行を阻止するロック壁を形成する。垂直降下部の深い面に対する角度は自由端をロック可能であれば厳密に垂直でなくてもよい。 When the card is pushed out, the free end 21a is disengaged from the engagement by the heart cam engagement portion 25a of the second recess 33 and passes through the third inclined surface 34 to the third projection 35 which becomes a shallow surface. climb. After that, the process proceeds to the third recess 36 that becomes a deep surface through the same vertical descent portion 35a. The third recess 36 corresponds to the card ejection operation start guide groove 121 of the prior art. The lock of the card push member 17 is completely released in the third recess 36. After that, the free end 21a follows the spring of the spring member 18 and goes up through the fourth inclined surface 37 to the fourth convex portion 38 which becomes a shallow surface, and then passes through the same one-step vertical descending portion 38a. It returns to the linear guide groove 27 which will be in an original standby state. The card push member 17 ejects the card by this series of movements.
The series of inclined surfaces 28, 31, 34, and 37 form an upward inclined surface with respect to the traveling direction of the free end 21a of the swing arm 21, and the series of vertical descending portions 29a, 32a, 35a, and 38a are formed on the free end 21a. A lock wall is formed to prevent retrograde movement. The angle of the vertical descent portion with respect to the deep surface may not be strictly vertical as long as the free end can be locked.

このようにして、カム要素２０において、そのカム溝２６に滑合している自由端２１ａは、カム溝２６を逆行すること無くそれに沿って一定方向に摺動し、カードプッシュ部材１７を上述したように適正に案内する。   In this way, in the cam element 20, the free end 21a sliding on the cam groove 26 slides in a certain direction along the cam groove 26 without going backward, and the card push member 17 is described above. Properly guide.

上述したように、本実施形態のカム要素２０では、ハート形カム２５の周囲に形成されるカム溝２６の底面は、図４（ｂ）に明示したように、基本的には一段の位置高低差しかない。すなわち、直線状ガイド溝２７を含み、第１の凹所３０、第２の凹所３３および第３の凹所３６から成る深い面と、第１の凸所２９、第２の凸所３２、第３の凸所３５および第４の凸所３８から成る浅い面との間の一段差である。このために、本実施形態のカードコネクタ１０では、図１０で説明したような従来のカム要素を有するカードコネクタに較べて、カム要素に必要な厚さが低減でき、その薄型化あるいは低背化が極めて容易になる。
また、浅い面を設けることにより、傾斜面の頂点部にかかる揺動アーム２１の自由端２１ａの力を面で受けることができるため、繰り返しプッシュイン・プッシュアウト機構１６を動作させた場合、傾斜面の頂点部の磨耗を軽減できる。 As described above, in the cam element 20 of the present embodiment, the bottom surface of the cam groove 26 formed around the heart-shaped cam 25 is basically one step higher and lower as shown in FIG. I will not. That is, it includes a straight guide groove 27, a deep surface including a first recess 30, a second recess 33, and a third recess 36, a first protrusion 29, a second protrusion 32, This is a level difference between the shallow surface formed by the third convex portion 35 and the fourth convex portion 38. For this reason, in the card connector 10 of the present embodiment, compared with the card connector having the conventional cam element as described in FIG. 10, the thickness required for the cam element can be reduced, and the thickness or height thereof can be reduced. Is extremely easy.
Also, since the surface of the free end 21a of the swing arm 21 applied to the apex of the inclined surface can be received by the surface by providing a shallow surface, when the push-in / push-out mechanism 16 is operated repeatedly, It is possible to reduce wear at the apex of the surface.

例えば、カム溝における一段の段差が０．１ｍｍ程度とすると、従来の技術では上述したように、少なくとも第１の段差Ａ〜第３の段差Ｃにより形成されるカム溝１１４の位置高低差は０．３ｍｍになる。これに対して、本実施形態のカム溝の高低差は一段の段差０．１ｍｍとなり０．２ｍｍの低背化を可能とする。ここで、microＳＤカードのようにカードの肉厚が０．７ｍｍ程度になり、カードコネクタ１０の厚さが２．０ｍｍ程度に薄くなってくると、従来技術に較べた本実施形態における上記０．２ｍｍの低背化は、カードコレクタ厚さの１０％強の低減になり大きな効果を有するようになる。このような低減効果は、カードが更に微小化しそのカードコネクタが小型化すると更に顕著なものになる。このように、本実施形態のカードコネクタ１０は、その低背化および小型化において極めて有効になってくる。   For example, if the level difference of one step in the cam groove is about 0.1 mm, the position difference of the cam groove 114 formed by at least the first step A to the third step C is 0 in the conventional technique as described above. .3mm. On the other hand, the height difference of the cam groove according to the present embodiment is a single step of 0.1 mm, which makes it possible to reduce the height by 0.2 mm. Here, when the thickness of the card becomes about 0.7 mm and the thickness of the card connector 10 becomes about 2.0 mm as in the case of a microSD card, the. A reduction in height of 2 mm has a great effect because it reduces the card collector thickness by more than 10%. Such a reduction effect becomes more prominent when the card is further miniaturized and the card connector is downsized. Thus, the card connector 10 of the present embodiment is extremely effective in reducing the height and size of the card connector 10.

上記実施形態では、カム溝２６底面を構成し深い面である直線状ガイド溝２７の一部、第１の凹所３０、第２の凹所３３および第３の凹所３６の高さ位置が同一となる場合について説明している。また、カム溝２６底面を構成する浅い面である、第１の凸所２９、第２の凸所３２、第３の凸所３５および第４の凸所３８の高さ位置が同一となる場合について説明している。本発明では、これ等の深い面の高さ位置はそれぞれに少し異なるようになっていてもよい。同様に、これ等の浅い面の高さ位置はそれぞれに少し異なるようになっていても構わない。   In the above embodiment, the height positions of a part of the linear guide groove 27 that forms the bottom surface of the cam groove 26 and is a deep surface, the first recess 30, the second recess 33, and the third recess 36 are as follows. The case where it becomes the same is demonstrated. Further, when the heights of the first convex portion 29, the second convex portion 32, the third convex portion 35, and the fourth convex portion 38, which are shallow surfaces constituting the bottom surface of the cam groove 26, are the same. It explains about. In the present invention, the height positions of these deep surfaces may be slightly different from each other. Similarly, the height positions of these shallow surfaces may be slightly different from each other.

次に、本実施形態のカードコネクタ１０へのカードの押圧および再押圧によるカードのロック、イジェクトの動作機構について図５ないし図７を参照して説明する。ここで、図５（ａ）は、カードをロック可能な状態まで挿入した状態を示す平面図であり、図５（ｂ）はそのときのプッシュイン・プッシュアウト機構１６の拡大図である。図６（ａ）は、カードをロック状態に挿入した状態を示す平面図であり、図６（ｂ）はそのときのプッシュイン・プッシュアウト機構１６の拡大図である。そして、図７（ａ）は、カードをイジェクト可能な状態まで再挿入した状態を示す平面図であり、図７（ｂ）はそのときのプッシュイン・プッシュアウト機構１６の拡大図である。   Next, a card locking / ejecting operation mechanism by pressing and re-pressing the card on the card connector 10 according to the present embodiment will be described with reference to FIGS. Here, FIG. 5A is a plan view showing a state where the card is inserted to a lockable state, and FIG. 5B is an enlarged view of the push-in / push-out mechanism 16 at that time. FIG. 6A is a plan view showing a state in which the card is inserted in a locked state, and FIG. 6B is an enlarged view of the push-in / push-out mechanism 16 at that time. 7A is a plan view showing a state in which the card is reinserted to a state where it can be ejected, and FIG. 7B is an enlarged view of the push-in / push-out mechanism 16 at that time.

なお、上記カードのカードコネクタ１０内への挿入においては、図３に示すように、下ハウジング部材１１の他側縁に設けられているスイッチ３９が働き、カード挿入の信号がカードコネクタ１０を取り付けている機器に伝送されるようになっている。   When the card is inserted into the card connector 10, as shown in FIG. 3, a switch 39 provided on the other side edge of the lower housing member 11 works, and a card insertion signal attaches the card connector 10. Is transmitted to the device.

図３に示したように、カード収容スペース１３内にmicroＳＤカード４０を収容していない時においては、カードプッシュ部材１７はバネ部材１８の弾発力により後退し、カード受口１４の一端に下ハウジング部材１１と一体に設けたストッパー２４に当接して待機状態となっている。   As shown in FIG. 3, when the microSD card 40 is not accommodated in the card accommodation space 13, the card push member 17 is retracted by the elastic force of the spring member 18, and is lowered to one end of the card receiving opening 14. Abutting on a stopper 24 provided integrally with the housing member 11 is in a standby state.

図５（ａ）に示すように、microＳＤカード４０の前端面を下ハウジング部材１１の前壁４１に当接するまでmicroＳＤカード４０を挿入する時、この挿入に伴い受圧斜面４０ａがカードプッシュ部材１７の加圧斜面１７ａを押圧し、バネ部材１８を圧縮させながらカードプッシュ部材１７を前進させる。   As shown in FIG. 5A, when the microSD card 40 is inserted until the front end surface of the microSD card 40 comes into contact with the front wall 41 of the lower housing member 11, the pressure receiving inclined surface 40 a of the card push member 17 The card push member 17 is advanced while pressing the pressure inclined surface 17 a and compressing the spring member 18.

この時、揺動アーム２１は、図５（ｂ）に示すようにカードプッシュ部材１７と一緒に前進し、同アーム２１の自由端２１ａをカム要素２０におけるカム溝の軌道に従い、カードロック作動可能な状態になる第１の凹所３０の位置まで進み、microＳＤカード４０はロック状態可能な状態になる。   At this time, the swing arm 21 moves forward together with the card push member 17 as shown in FIG. 5B, and the free end 21a of the arm 21 can be card-locked according to the cam groove track of the cam element 20. The microSD card 40 is in a state where it can be locked.

次に、図６（ａ）に示すように、microＳＤカード４０に対する押圧力を解除すると、カードプッシュ部材１７および揺動アーム２１はバネ部材１８の弾発力により僅かに後退し、ハート形カム２５のハートカム係止部２５ａに係合して後退を停止する。そして、揺動アーム２１の自由端２１ａは第２の凹所３３で係止される。   Next, as shown in FIG. 6A, when the pressing force against the microSD card 40 is released, the card push member 17 and the swing arm 21 are slightly retracted by the elastic force of the spring member 18, and the heart-shaped cam 25. Engage with the heart cam latching portion 25a of the camshaft to stop the backward movement. The free end 21 a of the swing arm 21 is locked by the second recess 33.

この結果、microＳＤカード４０は所定の挿入位置に停止しロック状態になる。そして、その電極パッド（不図示）はコンタクト１５の接触部１５ｂに加圧接触した状態に保たれる。   As a result, the microSD card 40 stops at a predetermined insertion position and enters a locked state. The electrode pad (not shown) is kept in pressure contact with the contact portion 15b of the contact 15.

次に、図７（ａ）に示すように、microＳＤカード４０を挿入方向へ再押圧して受圧斜面４０ａにより加圧斜面１７ａを押圧する。この押圧によりカードプッシュ部材１７はバネ部材１８を圧縮しつつ前壁４１に当接するまで僅かに前進する。この時、揺動アーム２１はカードプッシュ部材１７と一緒に前進し、第２の凹所３３から脱出し第３の凹所３６に進み、ロック解除可能な状態を形成する。   Next, as shown in FIG. 7A, the microSD card 40 is pressed again in the insertion direction, and the pressure inclined surface 17a is pressed by the pressure receiving inclined surface 40a. By this pressing, the card push member 17 advances slightly until it abuts against the front wall 41 while compressing the spring member 18. At this time, the swing arm 21 moves forward together with the card push member 17, escapes from the second recess 33, proceeds to the third recess 36, and forms an unlockable state.

次に、上記microＳＤカード４０の挿入方向への押圧力を解除すると、カードプッシュ部材１７はバネ部材１８の弾発力により後退し、加圧斜面１７ａが受圧斜面４０ａを押圧し、microＳＤカード４０をカード受口１４より一定量突出させる。即ちカードイジェクトを行う。この時、上記揺動アーム２１の自由端２１ａはカム要素２０のカム溝２６に沿い直線状ガイド溝２７に戻り、この揺動アーム２１に案内されてカードプッシュ部材１７が一緒に後退する。このようにして、microＳＤカード４０はカード受口１４より突出される。   Next, when the pressing force in the insertion direction of the microSD card 40 is released, the card push member 17 is retracted by the elastic force of the spring member 18, the pressure inclined surface 17 a presses the pressure receiving inclined surface 40 a, and the microSD card 40 is removed. A certain amount protrudes from the card receptacle 14. That is, card ejection is performed. At this time, the free end 21a of the swing arm 21 returns to the linear guide groove 27 along the cam groove 26 of the cam element 20, and the card push member 17 is retracted together by being guided by the swing arm 21. In this way, the microSD card 40 is protruded from the card receiving slot 14.

本実施形態では、上述したようにカム要素２０の薄型化あるいは低背化が容易になり、微小化するカードに対応したカードコネクタの低背化および小型化が可能になる。そして、このカム要素２０を備えたプッシュイン・プッシュアウト機構により、カードの押圧および再押圧によるカードのロック、イジェクトの動作が確実に行える。このようにして、電子機器あるいは携帯機器に使用される微小化したＩＣカードの利便性および安全性が向上する。   In the present embodiment, as described above, the cam element 20 can be easily reduced in thickness or height, and the card connector corresponding to the card to be miniaturized can be reduced in height and size. The push-in / push-out mechanism provided with the cam element 20 can reliably perform card locking and ejection operations by pressing and re-pressing the card. In this way, the convenience and safety of a miniaturized IC card used for electronic devices or portable devices is improved.

以上、本発明の好適な実施形態について説明したが、上述した実施形態は本発明を限定するものでない。当業者にあっては、具体的な実施態様において本発明の技術思想および技術範囲から逸脱せずに種々の変形・変更を加えることが可能である。   Although the preferred embodiments of the present invention have been described above, the above-described embodiments do not limit the present invention. Those skilled in the art can make various modifications and changes in specific embodiments without departing from the technical idea and technical scope of the present invention.

例えば、カム要素２０は、上記実施形態では下ハウジング部材１１に設けられているが、逆にカードプッシュ部材１７の前端領域に設け、揺動アーム２１は、その基端が下ハウジング部材１１の前端領域に形成した孔に回動可に支承され、その自由端が上記カードプッシュ部材１７の前端領域のカム要素２０のカム溝に滑合されるように配置してもよい。   For example, although the cam element 20 is provided in the lower housing member 11 in the above embodiment, conversely, the cam element 20 is provided in the front end region of the card push member 17, and the swing arm 21 has a base end at the front end of the lower housing member 11. It may be rotatably supported in a hole formed in the region, and its free end may be arranged so as to slide into the cam groove of the cam element 20 in the front end region of the card push member 17.

また、上記プッシュイン・プッシュアウト機構において、カードプッシュ部材１７を弾発させるバネ部材１８として、伸縮バネを有する構造にしてもよい。この場合、下ハウジング部材１１の側縁辺に取り付けられるカードプッシュ部材１７、バネ部材１８、カム要素２０等の配置は、実施形態で説明したものと異なってくる。   Further, in the push-in / push-out mechanism, the spring member 18 for resiliently pushing the card push member 17 may have a structure having an extension spring. In this case, the arrangement of the card push member 17, the spring member 18, the cam element 20, and the like attached to the side edge of the lower housing member 11 is different from that described in the embodiment.
