Description

本発明は、情報記憶媒体であるカードを着脱可能で、所定位置に装着したカードの外部電極にコンタクトを弾接させて信号の伝達が行えるカード用コネクタ装置に関するものである。   The present invention relates to a card connector device in which a card, which is an information storage medium, is detachable, and a signal can be transmitted by elastically contacting a contact with an external electrode of a card mounted at a predetermined position.

近年、メモリーカードとも称されるカードを容易に着脱できて小型薄型化や低コスト化も図りやすいカード用コネクタ装置が強く要望されている。こうした要望に応えるため、ホルダ等を介さずにカードをハウジングに直接装着できると共に、このハウジングに付設した弾性アーム片によって装着状態のカードを保持できるようにしたカード用コネクタ装置が従来提案されている(例えば、特許文献1参照)。   In recent years, there has been a strong demand for a card connector device that can easily attach and detach a card, also referred to as a memory card, and that can be easily reduced in size and thickness and cost. In order to meet these demands, a card connector device has been proposed in which a card can be directly mounted on a housing without using a holder or the like, and a mounted card can be held by an elastic arm piece attached to the housing. (For example, refer to Patent Document 1).

かかる従来のカード用コネクタ装置は、カード収納空間が設けられたハウジングと、カード収納空間へ突出する弾性接点片を有してハウジングに固定されたコンタクトと、ハウジングの左右両側壁の前端側に延設した一対の弾性アーム片とを備えており、各弾性アーム片の自由端部に形成された係合部がカード収納空間に入り込んでいる。このカード用コネクタ装置にカードを装着させる際には、まず、ハウジングの斜め上方からカードの前端部をカード収納空間の前端部に挿入し、カードの隅部によって一対の弾性アーム片の係合部(自由端部)をハウジングの左右外方へ押し撓める。次に、カードの後端部を下方のカード収納空間へ押し込んで、略水平な姿勢にした該カードを後方へスライド移動させることによって、各弾性アーム片の係合部をカードの隅部の前方へ弾性復帰させる。これにより、カードの前端部を一対の弾性アーム片で保持し、かつカードの後端部をカード収納空間の後端部で保持することができるため、カードをカード収納空間の所定位置に装着することができる。なお、こうしてカード用コネクタ装置に装着されたカードの外部電極には、対応するコンタクトの弾性接点片が弾接している。また、カードをカード用コネクタ装置から取り出す際には、装着状態のカードを前方へスライド移動させて、一対の弾性アーム片の係合部をハウジングの左右外方へ押し撓めた後、該カードの後端部を把持してハウジングの斜め上方へ抜き取る。   Such a conventional card connector device includes a housing provided with a card storage space, a contact having an elastic contact piece protruding into the card storage space and fixed to the housing, and extending to the front end sides of the left and right side walls of the housing. A pair of elastic arm pieces provided, and an engaging portion formed at the free end of each elastic arm piece enters the card storage space. When the card is mounted on the card connector device, first, the front end portion of the card is inserted into the front end portion of the card storage space from obliquely above the housing, and the engaging portions of the pair of elastic arm pieces are formed by the corner portions of the card. Push the (free end) to the left and right outward of the housing. Next, by pushing the rear end portion of the card into the lower card storage space and sliding the card in a substantially horizontal posture to the rear, the engaging portion of each elastic arm piece is moved forward of the corner of the card. Return to elasticity. Accordingly, the front end portion of the card can be held by the pair of elastic arm pieces and the rear end portion of the card can be held by the rear end portion of the card storage space, so that the card is mounted at a predetermined position in the card storage space. be able to. The elastic contact piece of the corresponding contact is in elastic contact with the external electrode of the card thus mounted on the card connector device. Further, when removing the card from the card connector device, the card in the mounted state is slid forward to push and bend the engaging portions of the pair of elastic arm pieces outwardly from the left and right sides of the housing. Grip the rear end of the housing and pull it out diagonally above the housing.

しかしながら、前述した従来のカード用コネクタ装置では、カードの着脱動作時に一対の弾性アーム片をハウジングの左右外方へ押し撓めるため、これら弾性アーム片の可動スペース分だけカード用コネクタ装置が平面的に大きなものになってしまい、小型化に支障をきたすという問題があった。また、ハウジングの側壁に延設された合成樹脂製の弾性アーム片を着脱時のカードによって繰り返し押し撓めると、弾性アーム片が塑性変形したり破損する虞があるため、かかる従来のカード用コネクタ装置は長寿命化が図りにくいという問題もあった。   However, in the conventional card connector device described above, since the pair of elastic arm pieces are pushed and bent to the left and right outward of the housing during the card attaching / detaching operation, the card connector device is flattened by the movable space of these elastic arm pieces. There is a problem that it becomes large in size and hinders downsizing. In addition, if the elastic arm piece made of synthetic resin extended on the side wall of the housing is repeatedly pushed and bent by the card at the time of attachment / detachment, the elastic arm piece may be plastically deformed or damaged. The connector device also has a problem that it is difficult to extend its life.

本発明は、このような従来技術の実情に鑑みてなされたものであり、その目的は、カードを容易に着脱できると共に、小型薄型化や低コスト化が図りやすくて長寿命なカード用コネクタ装置を安価に提供することにある。   The present invention has been made in view of the actual situation of the prior art as described above, and an object of the present invention is to provide a card connector device that can be easily attached / detached and that can be easily reduced in size and cost and reduced in cost and has a long life. Is to provide at a low cost.

上記の目的を達成するために、本発明では、カード収納空間が形成されたハウジングと、前記カード収納空間へ露呈する弾性接点片を有して前記ハウジングに固定されたコンタクトとを備え、外部電極を有するカードを前記カード収納空間の所定位置に装着することによって前記弾性接点片を前記外部電極に弾接させるカード用コネクタ装置において、前記ハウジングは合成樹脂材に金属板をインサート成形して一体化したものからなり、このハウジングが、前記カード収納空間の前端部を形成し装着途中および離脱途中の前記カードの前端部が挿入される前端受け部と、この前端受け部の後方かつ上方に段差部を介して設けられ装着完了状態の前記カードの前端部を保持する前端保持部と、前記カード収納空間の後端部を形成し装着完了状態の前記カードの後端部を保持する後端保持部とを有すると共に、前記前端保持部の天井壁が前記金属板の一部からなり、前記弾性接点片の弾性力に抗して前記カードを前記カード収納空間に配置させると共に、前記カードの前端部を前記前端受け部に挿入した状態で、前記カードの前端部が前記段差部を越えるまで前記カードを後方へスライド移動させることによって、前記弾性接点片に弾性付勢される前記カードの上動に伴い、該カードの前端部が前記前端保持部の前記天井壁に圧接状態で位置規制され、かつ前記カードの後端部が前記後端保持部に位置規制されるように構成した。 In order to achieve the above object, the present invention includes a housing in which a card storage space is formed, and a contact having an elastic contact piece exposed to the card storage space and fixed to the housing. In a card connector device in which the elastic contact piece is elastically contacted to the external electrode by mounting a card having a card at a predetermined position in the card storage space, the housing is integrated by insert molding a metal plate into a synthetic resin material The housing includes a front end receiving portion that forms a front end portion of the card storage space and into which the front end portion of the card being inserted and removed is inserted, and a stepped portion at the rear and above the front end receiving portion. A front end holding portion for holding the front end portion of the card in a mounted state, and a rear end portion of the card storage space. Wherein while closed and rear end holding portion for holding the rear end portion of the card, consists portion top wall of the front holding section of the metal plate, the card against the elastic force of the elastic contact piece Is placed in the card storage space, and the card is slid rearward until the front end of the card exceeds the stepped portion with the front end of the card inserted into the front end receiving portion. Along with the upward movement of the card that is elastically biased by the elastic contact piece, the position of the front end portion of the card is regulated in pressure contact with the ceiling wall of the front end holding portion, and the rear end portion of the card is the rear end. The position is regulated by the holding part.

このように構成されたカード用コネクタ装置は、操作者がカードの前端部をハウジングの前端受け部に挿入してカード収納空間内で該カードを後方へスライド移動させれば、コンタクトの弾性接点片の弾性力によって、カードの前端部と後端部がそれぞれハウジングの前端保持部と後端保持部に入り込んで位置規制された状態となるため、ホルダ等を介さずにカードをハウジングの所定位置に容易に装着することができ、小型薄型化も図りやすい。そして、かかる装着動作時に、後方へスライド移動するカードの前端部は、ハウジングの前端受け部に隣接する段差部を越えた時点で前端保持部へ入り込むため、カードをスライド移動させている操作者の手指に作用する弾性接点片の反力が急減してクリック感が生起される。したがって、操作者はこのクリック感によって、カードが所定位置に装着されたことを明瞭に認識することもできる。また、操作者が装着状態のカードの前端部を段差部の下面以下まで押し下げてから前方へスライド移動させれば、該前端部がハウジングの前端受け部に挿入されてカードは前端保持部や後端保持部に拘束されなくなるため、このカードをハウジングから容易に取り出すこともできる。また、このカード用コネクタ装置は、部品点数が少なくて組立作業が省略できる構成になっているため、安価に製造できる。しかも、このカード用コネクタ装置は、コンタクトの弾性接点片の弾性力を利用してカードの前後両端部がハウジングの前端保持部と後端保持部に保持されるようにしてあり、カードによって左右に押し撓められる合成樹脂製の弾性片をハウジングに形成する必要がないため、この点でも小型化に好適であり長寿命化も図りやすい。さらに、ハウジングが合成樹脂材に金属板をインサート成形して一体化したものからなり、前端保持部の天井壁がこの金属板の一部によって構成されることで、装着動作時に後方へスライド移動するカードの前端部が段差部を越えて前端保持部の天井壁に当接したときに、該カードの前端部が金属板からなる前端保持部の天井壁にぶつかって明瞭な衝突音(クリック音)を発生するため、操作者はこのクリック音とクリック感とによって、カードが所定位置に装着されたことを明瞭に認識することができる。 The card connector device configured as described above has an elastic contact piece for a contact when an operator inserts the front end portion of the card into the front end receiving portion of the housing and slides the card backward in the card storage space. Due to the elastic force of the card, the front end portion and the rear end portion of the card enter the front end holding portion and the rear end holding portion of the housing, respectively, so that the position of the card is regulated. It can be easily installed, and it is easy to reduce the size and thickness. During the mounting operation, the front end portion of the card that slides backward moves into the front end holding portion when it passes over the step portion adjacent to the front end receiving portion of the housing. The reaction force of the elastic contact piece acting on the finger is suddenly reduced, and a click feeling is generated. Therefore, the operator can clearly recognize that the card is mounted at a predetermined position by the click feeling. In addition, if the operator pushes the front end of the loaded card down to the lower surface of the stepped portion and slides it forward, the front end is inserted into the front end receiving portion of the housing, and the card is inserted into the front end holding portion and the rear Since the card is not restrained by the end holding portion, the card can be easily taken out from the housing. Further, the card connector device has a configuration in which the number of parts is small and the assembly work can be omitted, so that it can be manufactured at low cost. In addition, this card connector device uses the elastic force of the elastic contact piece of the contact so that the front and rear end portions of the card are held by the front end holding portion and the rear end holding portion of the housing. Since it is not necessary to form an elastic piece made of synthetic resin that can be pushed and bent in the housing, this point is also suitable for downsizing and it is easy to extend the life. In addition, the housing is made by integrally molding a metal plate on a synthetic resin material, and the ceiling wall of the front end holding part is constituted by a part of this metal plate, so that it slides backward during the mounting operation. When the front end of the card crosses the stepped portion and comes into contact with the ceiling wall of the front end holding part, the front end of the card hits the ceiling wall of the front end holding part made of a metal plate and a clear collision sound (click sound) Therefore, the operator can clearly recognize that the card is mounted at a predetermined position by the click sound and the click feeling.

上記の構成において、ハウジングに設けられた後端保持部の天井壁金属板の一部によって構成されされており、装着完了状態のカード後端部側がコンタクトの弾性接点片の弾性力によって該天井壁に圧接されるようにしてあると、カードが圧接される部分が金属であることから、合成樹脂製の受け部に比べて剛性が高まって破損などが生じにくく、コネクタ装置のさらなる長寿命化を図ることができる In the above configuration, the ceiling wall of the rear end holding portion provided in the housing is also configured by a part of the metal plate , and the rear end portion side of the card in the mounted state is caused by the elastic force of the elastic contact piece of the contact. If the card is pressed against the ceiling wall, the part where the card is pressed is metal, so the rigidity is higher and damage is less likely to occur compared to the receiving part made of synthetic resin. Can be achieved .

この場合において、インサート成形された金属板がハウジングの表面に露出していると共に、この金属板から導出された接地用端子がハウジングの底部側に配設されていると、カードの着脱時などにハウジングの表面に流れ込む静電気を接地用端子から外部の接地回路に逃がすことができるため、ハウジングに静電気が溜まらなくなって信頼性が向上する。 In this case, when the insert-molded metal plate is exposed on the surface of the housing and the grounding terminal led out from the metal plate is arranged on the bottom side of the housing, the card can be attached or detached. Static electricity flowing into the surface of the housing can be released from the grounding terminal to an external grounding circuit, so that static electricity does not accumulate in the housing and reliability is improved.

また、上記の構成において、カード収納空間へ突出する接点ばね片を有する検出スイッチをハウジングの後端保持部に付設し、装着完了状態のカードの後端部に該接点ばね片が押し込まれて弾性変形することによって該検出スイッチがオン動作するようにしてあると、カードが所定位置に装着されているか否かを検出スイッチの出力信号に基づいて検出できるようになる。しかも、操作者が装着状態のカードの前端部を段差部の下面以下まで押し下げると、接点ばね片の弾性力でカードが前方へスライド移動するため、カードの離脱動作が極めて容易に行えるようになる。 Further, in the above configuration, a detection switch having a contact spring piece protruding into the card storage space is attached to the rear end holding portion of the housing, and the contact spring piece is pushed into the rear end portion of the card in the mounted state to be elastic. If the detection switch is turned on by deformation, it can be detected based on the output signal of the detection switch whether or not the card is mounted at a predetermined position. In addition, when the operator pushes the front end of the card in the mounted state below the lower surface of the stepped portion, the card slides forward by the elastic force of the contact spring piece, so that the card can be removed easily. .

また、上記の構成において、カード収納空間へ突出する押圧ばね片をハウジングの前端受け部に付設し、カードの前端部が該押圧ばね片の弾性力に抗して該前端受け部に挿入されるようにしてあると、前端受け部に挿入されているときにカードの前端部は押圧ばね片によって後方へ弾性付勢されることになるため、カードを後方へスライド移動させるという装着動作が極めて容易に行えるようになる。   In the above configuration, the pressing spring piece protruding into the card storage space is attached to the front end receiving portion of the housing, and the front end portion of the card is inserted into the front end receiving portion against the elastic force of the pressing spring piece. In this way, the front end of the card is elastically urged rearward by the pressing spring piece when inserted into the front end receiving portion, so that the mounting operation of sliding the card rearward is extremely easy. Will be able to do.

本発明のカード用コネクタ装置は、操作者がカードの前端部をハウジングの前端受け部に挿入してカード収納空間内で該カードを後方へスライド移動させれば、コンタクトの弾性接点片の弾性力によって、カードの前端部と後端部がそれぞれハウジングの前端保持部と後端保持部に入り込んで位置規制された状態となるため、ホルダ等を介さずにカードをハウジングの所定位置に容易に装着することができ、小型薄型化も図りやすい。また、ハウジングが合成樹脂材に金属板をインサート成形して一体化したものからなり、前端保持部の天井壁がこの金属板の一部によって構成されることで、装着動作時に後方へスライド移動するカードの前端部が段差部を越えて前端保持部の天井壁に当接したときに、該カードの前端部が金属板からなる前端保持部の天井壁にぶつかって明瞭な衝突音を発生するため、操作者はこの衝突音とクリック感とによって、カードが所定位置に装着されたことを明瞭に認識することができる。 According to the card connector device of the present invention, when the operator inserts the front end portion of the card into the front end receiving portion of the housing and slides the card backward in the card storage space, the elastic force of the elastic contact piece of the contact is obtained. As a result, the front end and rear end of the card enter the front end holding part and the rear end holding part of the housing, respectively, so that the position of the card is regulated, so that the card can be easily mounted at a predetermined position on the housing without using a holder or the like. It is easy to reduce the size and thickness. In addition, the housing is made by integrally molding a metal plate on a synthetic resin material, and the ceiling wall of the front end holding portion is constituted by a part of this metal plate, so that it slides backward during the mounting operation. When the front end of the card crosses the stepped portion and comes into contact with the ceiling wall of the front end holding portion, the front end of the card hits the ceiling wall of the front end holding portion made of a metal plate to generate a clear collision sound. The operator can clearly recognize that the card is mounted at a predetermined position by the collision sound and the click feeling.

A curved contact portion 21a is formed at the free end of the elastic contact piece 21, and when the card 10 is mounted at a predetermined position, the contact portion 21a is in elastic contact with the corresponding external electrode 10a. (See FIG. 5). The connection terminal 22 is soldered together with the grounding terminal 3 to a predetermined land on a wiring board (not shown) on which the card connector device is mounted.

このように構成されたカード用コネクタ装置にカード10を装着する際には、まず図4の2点鎖線で示すように、操作者がハウジング1の斜め上方からカード10の前端部10bをカード収納空間Sの前端部(前端受け部4)に挿入した後、このカード10の後端部10cを下方のカード収納空間Sへ押し込んで、カード10を略水平な姿勢でカード収納空間Sに配置させる。この押し込み動作はコンタクト2群の各弾性接点片21の弾性力に抗して行われるため、各弾性接点片21は押し込み力によって図4に示す位置よりも下方へ撓んだ状態となる。   When the card 10 is mounted on the card connector device thus configured, first, as shown by a two-dot chain line in FIG. 4, the operator stores the front end portion 10 b of the card 10 from diagonally above the housing 1. After being inserted into the front end portion (front end receiving portion 4) of the space S, the rear end portion 10c of the card 10 is pushed into the lower card storage space S to place the card 10 in the card storage space S in a substantially horizontal posture. . Since this pushing operation is performed against the elastic force of each elastic contact piece 21 of the contact 2 group, each elastic contact piece 21 is bent downward from the position shown in FIG. 4 by the pushing force.

次に、図4の破線で示すように、操作者がカード10に押し込み力を加えたまま、前端部10bが段差部14aを越えるまでカード10を後方へスライド移動させる。これにより、各弾性接点片21の弾性力でカード10が上動するため、カード10の前端部10bがハウジング1の前端保持部5に入り込んで位置規制され、かつカード10の後端部10cがハウジング1の後端保持部6に入り込んで位置規制された状態となる。すなわち、カード10は前後両端部10b,10cが前端保持部5と後端保持部6に保持された状態になって、カード収納空間Sの所定位置に装着される。なお、かかる装着動作時に後方へスライド移動するカード10の前端部10bは、ハウジング1の前端受け部4に隣接する段差部14aを越えた時点で前端保持部5へ入り込むため、カード10をスライド移動させている操作者の手指に作用する弾性接点片21の反力が急減してクリック感が生起されると共に、カード10の前端部10bが前端保持部5の天井壁11a(第1金属板11の突出部分)に当接して衝突音(クリック音)が生起される。また、装着完了状態のカード10は各弾性接点片21の弾性力によって、前端部10bが天井壁11aに圧接され、かつ後端部10cが天井壁12aに圧接された状態になっている。   Next, as shown by a broken line in FIG. 4, the operator slides the card 10 backward until the front end portion 10 b exceeds the stepped portion 14 a while applying the pushing force to the card 10. Thereby, since the card 10 is moved upward by the elastic force of each elastic contact piece 21, the front end portion 10b of the card 10 enters the front end holding portion 5 of the housing 1 and is positioned, and the rear end portion 10c of the card 10 is The housing 1 enters the rear end holding portion 6 and is in a position-restricted state. That is, the front and rear end portions 10b and 10c are held by the front end holding portion 5 and the rear end holding portion 6 and the card 10 is mounted at a predetermined position in the card storage space S. Note that the front end portion 10b of the card 10 that slides backward during such mounting operation enters the front end holding portion 5 when it passes over the stepped portion 14a adjacent to the front end receiving portion 4 of the housing 1, so that the card 10 slides. The reaction force of the elastic contact piece 21 acting on the finger of the operator is suddenly reduced to cause a click feeling, and the front end portion 10b of the card 10 is connected to the ceiling wall 11a (first metal plate 11 of the front end holding portion 5). A collision sound (click sound) is generated. Further, the card 10 in the mounted state is in a state where the front end portion 10b is pressed against the ceiling wall 11a and the rear end portion 10c is pressed against the ceiling wall 12a by the elastic force of each elastic contact piece 21.

カード10の離脱動作について説明すると、カード用コネクタ装置から装着状態のカード10を取り出す際には、まず操作者がカード10の前端部10bを段差部14aの下面以下まで押し下げて、このカード10を前方へスライド移動させることにより、カード10の前端部10bをハウジング1の前端保持部5から脱出させて前端受け部4に挿入する。これにより、カード10はハウジング1の前端保持部5や後端保持部6に拘束されなくなるため、操作者は後端部10cを手指で把持してカード10をハウジング1の斜め上方へ容易に抜き取ることができる。   The removal operation of the card 10 will be described. When the card 10 in the mounted state is taken out from the card connector device, the operator first pushes down the front end portion 10b of the card 10 below the lower surface of the stepped portion 14a. By sliding forward, the front end portion 10 b of the card 10 is removed from the front end holding portion 5 of the housing 1 and inserted into the front end receiving portion 4. As a result, the card 10 is not restrained by the front end holding portion 5 and the rear end holding portion 6 of the housing 1, so that the operator can easily pull the card 10 obliquely upward of the housing 1 by holding the rear end portion 10 c with fingers. be able to.

このように本実施形態例に係るカード用コネクタ装置は、操作者がカード10の前端部10bをハウジング1の前端受け部4に挿入して、カード収納空間S内でカード10を後方へスライド移動させれば、コンタクト2の弾性接点片21の弾性力によって、カード10の前端部10bと後端部10cがそれぞれハウジング1の前端保持部5と後端保持部6に入り込んで位置規制された状態となるため、ホルダ等を介さずにカード10をハウジング1の所定位置に容易に装着することができ、小型薄型化も図りやすい。そして、かかる装着動作時に、後方へスライド移動するカード10の前端部10bは、ハウジング1の段差部14aを越えた時点で前端保持部5へ入り込むため、カード10をスライド移動させている操作者の手指にクリック感が伝わると共に、カード10の前端部10b側が前端保持部5の天井壁11aに当接してクリック音が生起される。したがって、操作者はこのクリック感とクリック音とによって、カード10が所定位置に装着されたことを明瞭に認識することができる。   Thus, in the card connector device according to this embodiment, the operator inserts the front end portion 10b of the card 10 into the front end receiving portion 4 of the housing 1, and slides the card 10 backward in the card storage space S. Then, the front end portion 10b and the rear end portion 10c of the card 10 enter the front end holding portion 5 and the rear end holding portion 6 of the housing 1 and are regulated by the elastic force of the elastic contact piece 21 of the contact 2, respectively. Therefore, the card 10 can be easily attached to a predetermined position of the housing 1 without using a holder or the like, and the size and thickness can be easily reduced. During the mounting operation, the front end portion 10b of the card 10 that slides backward moves into the front end holding portion 5 at the time when it exceeds the stepped portion 14a of the housing 1, so that the operator who slides the card 10 moves. A click feeling is transmitted to the fingers, and the front end portion 10b side of the card 10 comes into contact with the ceiling wall 11a of the front end holding portion 5 to generate a click sound. Therefore, the operator can clearly recognize that the card 10 is mounted at a predetermined position by the click feeling and the click sound.

また、このカード用コネクタ装置は、部品点数が少なくて組立作業が省略できる構成になっているため、安価に製造できる。しかも、このカード用コネクタ装置は、コンタクト2群の各弾性接点片1の弾性力を利用してカード10の前後両端部10b,10cがハウジングの前端保持部5と後端保持部6に保持されるようにしてあり、カード10によって左右に押し撓められる合成樹脂製の弾性片をハウジング1に形成する必要がないため、この点でも小型化に好適であり長寿命化も図りやすい。   Further, the card connector device has a configuration in which the number of parts is small and the assembly work can be omitted, so that it can be manufactured at low cost. Moreover, in this card connector device, the front and rear end portions 10b and 10c of the card 10 are held by the front end holding portion 5 and the rear end holding portion 6 of the housing using the elastic force of each elastic contact piece 1 of the contact 2 group. Since it is not necessary to form an elastic piece made of a synthetic resin that is pushed and deflected left and right by the card 10 in the housing 1, this point is also suitable for downsizing and easily extending the life.

また、このカード用コネクタ装置では、1枚の金属板からなる第1ないし第3金属板11,12,13がインサート成形加工によってハウジング1に一体化されているため、ハウジング1の機械的強度が高まっている。しかも、これら第1ないし第3金属板11,12,13がハウジング1の表面に露出しており、かつ第1ないし第3金属板11,12,13から導出された各接地用端子3がハウジング1の底部側に配設されているため、カード10の着脱時などにハウジング1の表面に流れ込む静電気を接地用端子3から外部の接地回路へ逃がすことができる。それゆえ、このカード用コネクタ装置は、ハウジング1に静電気が溜まる虞がなく、静電気に起因する事故を未然に防止できて信頼性が高まっている。   Further, in this card connector device, the first to third metal plates 11, 12, 13 made of a single metal plate are integrated with the housing 1 by insert molding, so that the mechanical strength of the housing 1 is increased. It is growing. In addition, the first to third metal plates 11, 12, 13 are exposed on the surface of the housing 1, and each grounding terminal 3 led out from the first to third metal plates 11, 12, 13 is the housing. 1, the static electricity that flows into the surface of the housing 1 when the card 10 is attached or detached can be released from the grounding terminal 3 to an external grounding circuit. Therefore, the card connector device has no fear of static electricity in the housing 1 and can prevent accidents caused by the static electricity, thereby increasing reliability.

図8は本発明の第2実施形態例に係るカード用コネクタ装置の下面図であり、図7と対応する部分には同一符号が付してあるため重複する説明は省略する。   FIG. 8 is a bottom view of the card connector device according to the second embodiment of the present invention, and portions corresponding to those in FIG.

図8に示すカード用コネクタ装置は、ハウジング1の前端受け部4に押圧ばね片7が付設されている点と、接点ばね片9を含む検出スイッチ8がハウジング1の後端保持部6に付設されている点とが、前述した第1実施形態例と異なっている。   In the card connector device shown in FIG. 8, a pressing spring piece 7 is attached to the front end receiving portion 4 of the housing 1, and a detection switch 8 including a contact spring piece 9 is attached to the rear end holding portion 6 of the housing 1. This is different from the first embodiment described above.

すなわち、図8に示すカード用コネクタ装置では、押圧ばね片7がカード収納空間Sの前端部に突出しており、この押圧ばね片7の弾性力に抗してカード10の前端部が前端受け部4に挿入されるようになっている。したがって、前端受け部4に挿入されたカード10の前端部は押圧ばね片7によって後方へ弾性付勢されることになり、該カード10を後方へスライド移動させるという装着動作を極めて容易に行うことができる。なお、この第2実施形態例では、押圧ばね片7をハウジング1の前壁14に固設されている第1金属板11から延出して形成しているが、押圧ばね片7を第1金属板11とは別の部材として形成してもよい。   That is, in the card connector device shown in FIG. 8, the pressing spring piece 7 protrudes from the front end portion of the card storage space S, and the front end portion of the card 10 resists the elastic force of the pressing spring piece 7. 4 is inserted. Therefore, the front end portion of the card 10 inserted into the front end receiving portion 4 is elastically urged rearward by the pressing spring piece 7, and the mounting operation of sliding the card 10 rearward can be performed very easily. Can do. In the second embodiment, the pressing spring piece 7 is formed to extend from the first metal plate 11 fixed to the front wall 14 of the housing 1. However, the pressing spring piece 7 is formed from the first metal. You may form as a member different from the board 11. FIG.

また、図8に示すカード用コネクタ装置では、一対の接点ばね片9,9がカード収納空間Sの後端部に突出しており、装着完了状態のカード10の後端部に当接する一方の接点ばね片9がカード10により押し込まれて他方の接点ばね片9側に弾性変形することによって、双方の接点ばね片9,9が接触導通して検出スイッチ8がオン動作するようになっている。そのため、カード10が所定位置に装着されているか否かを、検出スイッチ8の出力信号に基づいて検出することができる。しかも、操作者が装着状態のカード10の前端部を段差部14aの下面以下まで押し下げると、これら接点ばね片9,9の弾性力でカード10が前方へスライド移動するため、カードの離脱動作を極めて容易に行うことができる。なお、この第2実施形態例では、一対の接点ばね片9,9を第1〜第3金属板11〜13と異なる別の金属板で形成しているが、一方の接点ばね片9をハウジング1の後壁15に固設されている第2金属板12から延出して形成してもよい。また、検出スイッチ8として第2実施形態例とは別の構成のものを採用してもよく、さらに、検出スイッチ8が配設される部位はカード収納空間Sの後端部側に限らず、カード収納空間Sの前端部側や側端部側や底部側であってもよい。   Further, in the card connector device shown in FIG. 8, the pair of contact spring pieces 9, 9 protrudes from the rear end portion of the card storage space S, and is one contact point that contacts the rear end portion of the card 10 in the mounted state. When the spring piece 9 is pushed by the card 10 and is elastically deformed toward the other contact spring piece 9, the contact spring pieces 9 and 9 are brought into contact with each other and the detection switch 8 is turned on. Therefore, whether or not the card 10 is mounted at a predetermined position can be detected based on the output signal of the detection switch 8. In addition, when the operator pushes the front end of the card 10 in the mounted state below the lower surface of the stepped portion 14a, the card 10 slides forward due to the elastic force of the contact spring pieces 9, 9, so that the card is removed. It can be done very easily. In the second embodiment, the pair of contact spring pieces 9, 9 are formed of another metal plate different from the first to third metal plates 11-13. The first metal plate 12 may be formed so as to extend from the second metal plate 12 fixed to the rear wall 15. The detection switch 8 may have a configuration different from that of the second embodiment, and the part where the detection switch 8 is disposed is not limited to the rear end side of the card storage space S. It may be the front end side, the side end side, or the bottom side of the card storage space S.

以上説明したように、本発明は、カードを容易に着脱できると共に、小型薄型化や低コスト化が図りやすいカード用コネクタに有用である。   As described above, the present invention is useful for a card connector in which a card can be easily attached and detached, and which can be easily reduced in size and thickness and cost.
