Description

【0001】
【発明の属する技術分野】
本発明は、ICチップ、ICモジュール等との接続や保持に使用されるソケット装置の構造に関する。
【0002】
【従来の技術】
従来のICチップ等を保持するソケット装置としては、装着するICを保持するために、ハウジングのコーナ部分に回動可能なラッチアーム部材を配設して、ハウジングにICを装着した後に、このラッチアーム部材でICを上方から抑えつけて保持するようにした構成のものが知られている(例えば、特許文献1参照)。
【0003】
以下、従来のソケット装置の構造を図に基づいて説明する。図11は従来のソケット装置の平面図、図12はラッチアームによる保持状態を示す側面図である。
【0004】
図において、基盤31は合成樹脂製で略方形をしており、その略中央に開口するIC収容部32を有する。このIC収容部32は略方形をしており、このIC収容部32に略方形のIC33を収容する。このIC収容部32に対向する4辺には台座34が設けられ、この台座34にIC33のリードを支持するものとなっている。
【0005】
前記基盤31の各コーナ部にはラッチアーム36を配し、このラッチアーム36を貫通室38内に収容し、軸部35をもって回動可能に支持している。ラッチアーム36はIC収容部32の対角線上に沿って斜めに延在しており、軸部35を支点として対角線上に上下に回動する。そして、下方回動時には、IC収容部32内に収容されたIC33の各コーナ部に係合し、上方回動時には、該係合を解除するように形成されている。また、ラッチアーム36の内端である、先端には上記IC33に係脱する係合爪36aが設けられている。
【0006】
また、ラッチアーム36の軸支部から後方へバネ片36bを突設してあり、このバネ片36bは上記対角線上に沿って延び、その自由端部36dは貫通室38の後部内壁に形成した傾斜面からなるバネ受部39に当接されている。このバネ片36bはラッチアーム36が上方回動したときに、自由端部36dがバネ受部39に当接して回動を阻止されることにより反り曲がり弾力を蓄えるものとなる。
【0007】
ラッチアーム36の開閉手段としては、冶具により弧形曲部からなるの受圧部36eを押圧することでラッチアーム36を上下に回動して行うものとされ、受圧部36eが押し上げられたときにラッチアーム36が上方へ回動して解除状態を形成する。この状態でIC33のIC収容部32への装着及び取り出しが行われる。
【0008】
次いで、受圧部36eへの押圧力を取り除くと、ラッチアーム36はバネ片36bの復元力により自動的に下方へ回動しIC33のコーナ部上面に係合する。これによってIC33が基盤31に保持されるものとなる。このとき、バネ片36bの弾力により係止爪36aをIC33のコーナ部に軽く押し当て係合を確保している。

【発明が解決しようとする課題】
しかしながら、上記した従来のソケット装置の構成においては、IC33を基盤31のIC収容部32に保持させるのに、基盤31に回動可能に軸支されたラッチアーム36を使用する構成のため、基盤31にはラッチアーム36を収容するスペースが必要となり、ソケット装置の小型化、薄型化が要求される場合には、その対応が困難であるという問題があった。
【0011】
従って、本発明では上述した問題点を解決し、薄型化、小型化が可能であり、しかも、装着した電気部品を確実に保持できるソケット装置を提供することを目的とする。
【0012】
【課題を解決するための手段】
上記課題を解決するために本発明では第1の解決手段として、電気部品が装着される凹状の収納部を有するハウジングと、このハウジングの収納部内に並設され、前記電気部品の外部接触片と接続される複数の端子部材と、前記電気部品を前記収納部に保持して抜け止めする抜け止め部材とを備え、前記抜け止め部材は、前記ハウジングの外側面に沿って配設された薄板状の基板部と、この基板部の一部に設けられたスリットにより横方向に長尺状に延在すると共に、前記ハウジングの外側面に対して外方向に弾性変形可能に形成された弾性アーム部とからなり、前記弾性アーム部の先端側に前記電気部品の上方に係合して抜け止めする係合部を形成し、前記電気部品が装着される際には、前記弾性アーム部が外方向へ弾性変形すると共に、前記電気部品が前記収納部に装着された時には、前記係合部が前記電気部品の上方に係合して抜け止めされる構成とした。
【0013】
また、第2の解決手段として、前記ハウジングは、4辺を有する方形状に形成され、前記抜け止め部材は、前記ハウジングの対向する4辺の外側面の内、少なくとも対向する2面にそれぞれ配設されている構成とした。
また、第3の解決手段として、前記抜け止め部材を、導電性の金属板で形成し、この金属板を折り曲げることにより、前記ハウジングの外側面に沿って配設した構成とした。
【0014】
また、第4の解決手段として、前記複数の端子部材は、前記凹状の収納部の周縁部に並設されており、前記抜け止め部材の基板部は、前記端子部材の近傍に配設されて、前記端子部材を外方から取り囲むように前記ハウジングの外周面に沿って配設されると共に、前記基板部をソケット装置が実装される回路基板のグランドに接地した構成とした。
また、第5の解決手段として、前記抜け止め部材の係合部には傾斜面が形成されており、前記電気部品が装着される際には、前記傾斜面に沿って前記電気部品が挿入されることにより、前記弾性アーム部が外方向へ弾性変形する構成とした。
【0015】
【発明の実施の形態】
以下、本発明の実施形態を図1乃至図10に示す。図1は本発明のソケット装置の平面図、図2はソケット装置の端子部材の一部を破断して示す正面図、図3はソケット装置の抜け止め部材の一部を破断して示す側面図、図4はICモジュールを装着した状態を示す平面図、図5はICモジュールを装着した状態で端子部材の一部を破断して示す正面図、図6はICモジュールを装着した状態で抜け止め部材の一部を破断して示す側面図、図7は抜け止め部材が撓んだ状態を示す側面図、図8は抜け止め部材を示す斜視図、図9はICモジュールを示す平面図、図10はICモジュールを示す正面図である。
尚、図4においては、一部、抜け止め部材が撓んだ状態も便宜的に示している。
【0016】
図において、ハウジング1は、合成樹脂などの絶縁材からなり、上面が開口された凹状の収納部1aを有する方形の箱型に形成されている。この凹状の収納部1aの4辺周縁部には、複数の端子部材2がそれぞれ対向した状態で並設されて取り付けられている。
【0017】
前記端子部材2は、導電性の金属板からなり、ハウジング1に保持される平板状の基部と、この基部の一端側にU字状に屈曲されて基部と平行に折り曲げられて形成された接点板2aと、他端側に同じくL字状に屈曲されてその先端がハウジング1の底面外方へ延出された接続板2bとを有している。また、前記接点板2aの先端側はさらに収納部1aの内方へ屈曲されており、この屈曲片2cが後述するICモジュール4の外部接触片4cと接触して導通されるものとなっている。
【0018】
抜け止め部材3は、薄板状の導電性の金属板からなり、この抜け止め部材3には4枚連続して折り曲げることにより方形状に形成された基板部3aが設けられている。この抜け止め部材3は、それぞれの基板部3aが方形状のハウジング1の外方を囲むように、ハウジング1の4辺の外側面に沿って配設されている。
また、基板部3aの上面側には、それぞれの基板部3aを連結する桟部3bが形成されており、この桟部3bが、ハウジング1の収納部1aの外側部上面に係合されて抜け止め部材3がハウジング1に取り付けられるものとなっている。
【0019】
また、少なくとも対向する2つの基板部3aの上面側には、L字状のスリット3cを介して弾性変形可能なように、横方向(後述するICモジュール4の挿入方向とは直交する方向)に長尺状に延設された弾性アーム部3dが形成されている。この弾性アーム部3dは、基板部3aの長手方向となる横方向に沿って長尺状となるように形成されており、ハウジング1の凹状の収納部1aの形成方向(ICモジュール4の挿入方向)に対して直交する方向に弾性変形し易く形成されている。尚、この弾性アーム部3dは、4つの基板部3aの全てに形成するようにしてもよい、
【0020】
このように、弾性アーム部3dを、ハウジング1の対向する4辺の外側面の内、少なくとも対向する2面にそれぞれ配設するようにすれば、互いに対向する方向に弾性アームの弾性力が作用するので、後述するIモジュール4を抜け止め部材3に確実に保持することができる。
また、抜け止め部材3を、導電性の金属板で形成し、金属板を折り曲げることにより、ハウジング1の外側面に沿って配設するようにしたので、薄板状に形成しても弾性力が確実に得られると共に、加工が容易で安価対応が可能となっている。
【0021】
また、この弾性アーム部3dの自由端側でハウジング1の上面側には、収納部1aに挿入されるICモジュール4の上方に係合して抜け止めする係合部3eが形成されている。この係合部3eは、弾性アーム部3dから折り曲げられて収納部1aの底面側へ屈曲されて形成されており、この係合部3eは収納部1aの底面中央に向かって傾斜する傾斜面3fを有するように形成されている。この傾斜面3fを設けることによりICモジュール4が挿入された際、弾性アーム部3dが傾斜面3fに沿ってハウジングの外方へ弾性変形されて撓むものとなる。
傾斜面3fを設けることにより、簡単な構成で弾性アーム部3dを弾性変形させることができるので、ICモジュール4と抜け止め部材3との確実な係合力が得られるものとなる。
【0022】
また、抜け止め部材3の基板部3aの下面側には、下方へ突出した接地片3gが設けられており、この接地片3gが、ソケット装置が実装される回路基板のグランドに接地されるものとなっている。
この場合、ハウジング1に並設された複数の端子部材2は、凹状の収納部1aの周縁部に並設されており、抜け止め部材3の基板部3aは、端子部材2の近傍に配設されて、端子部材2を外方から取り囲むようにハウジング1の外周面に沿って配設されるものとなっていることから、抜け止め部材3がシールド板として働くので、端子部材2に対するシールド効果を高めることができるものとなっている。
【0023】
電気部品の一例としてのカメラモジュールであるICモジュール4は、内部に半導体(IC)などの素子が集積された回路部品であり、方形状の基台部4aと、この基台部4aの上面側に突出された円形状のレンズ部4bとを有している。また、基台部4aには、4つの側面の下端側から底面に連続した複数の外部接触片4cが設けられており、この外部接触片4cがハウジング1の収納部1aの複数の端子部材2と接続されるものとなっている。
【0024】
また、基台部4aの、対角線上に対向する上面側の2角部には係止溝部4dが設けられている。この係止溝部4dに、抜け止め部材3の弾性アーム部3dに形成された係合部3eが係合されて、ICモジュール4がハウジング1の収納部1aに保持されるものとなっている。
尚、レンズ部4bは、携帯電話機やデジタルカメラなどの撮影機能として用いられる場合のカメラレンズとして使用されるものである。
【0025】
次に、上記構成のソケット装置にICモジュール4を装着する場合の動作を図4ないし図7を用いて説明する。
まず、ハウジング1の収納部1aの上方から、ICモジュール4を基台部4aの底面側を下にして挿入する。この時、ICモジュール4の基台部4aの底面及び側面が、抜け止め部材3の弾性アーム部3dの自由端側に形成された係合部3eの傾斜面3fに沿って下方へ移動し、この移動に伴って、図4、図7に部分的に示すように弾性アーム部3dが自身の持つばね性により外方へ弾性変形して撓むものとなる。
この時、弾性アーム部3dは、抜け止め部材3の基板部3aの横方向に沿って長尺状に形成されているので、十分な弾性を有して撓むものとなる。
【0026】
そして、ICモジュール4の上面側に形成された係止溝部4dに、前記係合部3eの先端部が達すると、図4、図6に部分的に示すように前記係合部3eが係止溝部4dに落ち込むことにより係合されるものとなる。
この時、前記係合部3eは、弾性アーム部3d自身の持つばね性によって内方、すなわち、ICモジュール4の係止溝部4d側に付勢されるものとなり、ばね性を持って弾圧され、ICモジュール4は確実にハウジング1の収納部1aに保持されるものとなる。
【0027】
そして、ICモジュール4が収納部1aに保持されると、図5に示すように、ICモジュール4の基台部4aに設けられた複数の外部接触片4cが、収納部1aの周縁部に配設された、複数の端子部材2の接点板2aの先端に設けられた屈曲片2cと接触することにより、電気的に導通されるものとなる。
この時、端子部材2の接点板2aは、U字状に折り曲げられて形成されており、自身の持つばね性で屈曲片2cを外部接触片4cに弾接するものとなり、確実に接触し、安定した接触が得られるものとなっている。
【0028】
上記した本発明の実施例によれば、抜け止め部材3を、ハウジング1の外側面に沿って配設された薄板状の基板部3aと、この基板部3aに弾性変形可能に設けられた弾性アーム部3dとで形成して、この弾性アーム部3dを、基板部3aの横方向(ICモジュール4の挿入方向とは直交する方向)に長尺状に延設すると共に、弾性アーム部3dの先端側にICモジュール4の係止溝部4dに係合して抜け止めする係合部3eを形成して、ICモジュール4が装着される際には、弾性アーム部3dが外方向へ弾性変形すると共に、ICモジュール4が収納部1aに装着された時には、係合部3eがICモジュール4の係止溝部4dに係合して抜け止めされることから、ICモジュール4をソケット装置に装着して保持する際には、抜け止めを行う係合部3eを有する弾性アーム部3dを、ハウジング1の外側面に沿って横方向に、且つ、長尺状に伸ばして形成したので、弾性アーム部3dの長さを十分に確保し、係合部3eの弾性力を維持しながら寸法を小さくすることができるため、ソケット装置の小型化、薄型化が図れるものとなっている。
【0029】
尚、上記の実施例においては、抜け止め部材3の基板部3aの下面側に、接地片3gを形成し、この接地片3gを、ソケット装置が実装される回路基板のグランドに接地するようにしており、これに加えて、ICモジュール4の係止溝部4dにも接地用の接触片(図示せず)を形成し、この接地用の接触片と抜け止め部材3の弾性アーム部3dの係合部3eとを接続して、ICモジュール4を直接ソケット装置が実装される回路基板のグランドに接地するようにしてもよい。
【0030】
【発明の効果】
以上説明したように、本発明のソケット装置は、電気部品が装着される凹状の収納部を有するハウジングと、ハウジングの収納部内に並設され、電気部品の外部接触片と接続される複数の端子部材と、電気部品を収納部に保持して抜け止めする抜け止め部材とを備え、抜け止め部材は、ハウジングの外側面に沿って配設された薄板状の基板部と、基板部に弾性変形可能に設けられた弾性アーム部とからなり、弾性アーム部を、基板部の横方向に長尺状に延設すると共に、弾性アーム部の先端側に電気部品の上方に係合して抜け止めする係合部を形成し、電気部品が装着される際には、弾性アーム部が外方向へ弾性変形すると共に、電気部品が収納部に装着された時には、係合部が電気部品の上方に係合して抜け止めされることから、電気部品をソケット装置に装着して保持する際に、抜け止めを行う係合部を有する弾性アーム部を、ハウジングの外側面に沿って横方向に、且つ、長尺状に伸ばして形成したので、弾性アーム部の長さを十分に確保し、係合部の弾性力を維持しながら寸法を小さくすることができるため、ソケット装置の小型化、薄型化が図れる。
【0031】
また、ハウジングは、4辺を有する方形状に形成され、抜け止め部材は、ハウジングの対向する4辺の外側面の内、少なくとも対向する2面にそれぞれ配設されていることから、互いに対向する方向に弾性アームの弾性力が作用するので、電気部品を抜け止め部材に確実に保持することができる。
また、抜け止め部材を、導電性の金属板で形成し、金属板を折り曲げることにより、ハウジングの外側面に沿って配設したことから、薄板状に形成しても弾性力が確実に得られると共に、加工が容易で安価対応が可能となる。
【0032】
また、複数の端子部材は、凹状の収納部の周縁部に並設されており、抜け止め部材の基板部は、端子部材の近傍に配設されて、端子部材を外方から取り囲むようにハウジングの外周面に沿って配設されると共に、基板部をソケット装置が実装される回路基板のグランドに接地したことから、抜け止め部材がシールド板として働くので、端子部材に対するシールド効果を高めることができる。
また、抜け止め部材の係合部には傾斜面が形成されており、電気部品が装着される際には、傾斜面に沿って電気部品が挿入されることにより、弾性アーム部が外方向へ弾性変形することから、簡単な構成で弾性アーム部を弾性変形させることができるので、電気部品と抜け止め部材との確実な係合力が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a structure of a socket device used for connection or holding with an IC chip, an IC module, or the like.
[0002]
[Prior art]
As a conventional socket device for holding an IC chip or the like, in order to hold an IC to be mounted, a rotatable latch arm member is disposed at a corner portion of the housing, and this latch is mounted after the IC is mounted on the housing. There is known a configuration in which an IC is held from above by an arm member (see, for example, Patent Document 1).
[0003]
Hereinafter, the structure of a conventional socket device will be described with reference to the drawings. FIG. 11 is a plan view of a conventional socket device, and FIG. 12 is a side view showing a holding state by a latch arm.
[0004]
In the figure, a base 31 is made of a synthetic resin and has a substantially square shape, and has an IC accommodating portion 32 that opens at a substantially center thereof. The IC housing portion 32 has a substantially square shape, and a substantially square IC 33 is housed in the IC housing portion 32. A pedestal 34 is provided on the four sides facing the IC housing portion 32, and the pedestal 34 supports the leads of the IC 33.
[0005]
A latch arm 36 is disposed at each corner portion of the base 31, and the latch arm 36 is accommodated in a through chamber 38 and is rotatably supported by a shaft portion 35. The latch arm 36 extends obliquely along the diagonal line of the IC housing portion 32 and pivots up and down on the diagonal line with the shaft portion 35 as a fulcrum. And, it is formed so as to engage with each corner portion of the IC 33 accommodated in the IC accommodating portion 32 when rotating downward, and to release the engagement when rotating upward. Further, an engaging claw 36 a that engages with and disengages from the IC 33 is provided at the tip, which is the inner end of the latch arm 36.
[0006]
Further, a spring piece 36b protrudes rearward from the shaft support portion of the latch arm 36, the spring piece 36b extends along the diagonal line, and a free end portion 36d thereof is an inclination formed on the rear inner wall of the through chamber 38. It is in contact with a spring receiving portion 39 consisting of a surface. When the latch arm 36 is rotated upward, the spring piece 36b is warped and stored by the free end portion 36d coming into contact with the spring receiving portion 39 to prevent the rotation.
[0007]
As a means for opening and closing the latch arm 36, the latch arm 36 is rotated up and down by pressing the pressure receiving portion 36e made of an arcuate curved portion with a jig, and when the pressure receiving portion 36e is pushed up. The latch arm 36 pivots upward to form a release state. In this state, the IC 33 is attached to and removed from the IC housing portion 32.
[0008]
Next, when the pressing force to the pressure receiving portion 36e is removed, the latch arm 36 automatically rotates downward by the restoring force of the spring piece 36b and engages with the upper surface of the corner portion of the IC 33. As a result, the IC 33 is held on the base 31. At this time, the engaging claw 36a is lightly pressed against the corner portion of the IC 33 by the elasticity of the spring piece 36b to ensure engagement.
[0009]
[Patent Document 1]
Japanese Patent Laid-Open No. 5-65186
[Problems to be solved by the invention]
However, in the configuration of the conventional socket device described above, since the IC 33 is held in the IC housing portion 32 of the base 31, the latch arm 36 pivotally supported by the base 31 is used. No. 31 requires a space for accommodating the latch arm 36, and there is a problem that it is difficult to cope with the reduction in size and thickness of the socket device.
[0011]
Accordingly, it is an object of the present invention to provide a socket device that solves the above-described problems, can be reduced in thickness and size, and can securely hold the mounted electrical component.
[0012]
