Description

【0001】
【発明の属する技術分野】
本発明は、ICパッケージなどの電気部品を着脱可能に保持して外部の測定器に電気的に接続させる電気部品用ソケットに関し、詳しくは、上記電気部品を押圧して固定する押圧カバーを閉じた状態のときにその全体の高さを低くすることができる電気部品用ソケットに関するものである。
【0002】
【従来の技術】
一般に、ICパッケージなどの電気部品についての性能検査を行うときには、電気部品を着脱可能に保持して外部の測定器に電気的に接続させる電気部品用ソケットが用いられる。従来のこの種の電気部品用ソケットのうち、いわゆるクラムシェルタイプのものは、電気部品を載置する載置部が設けられたソケット本体と、このソケット本体の一端側に設けられた回転軸にて開閉可能に軸支され閉じた状態で載置部に載置された電気部品を押圧して固定する押圧カバーと、前記ソケット本体の一端側に設けられた他の回転軸にて開閉可能に軸支され押圧カバーが閉じる方向に作動力を与えて閉じるレバー部材とを備えて成る。
【0003】
そして、このような電気部品用ソケットを使用して電気部品を保持するときには、まずレバー部材及び押圧カバーを開いてソケット本体の載置部に電気部品を載置し、次にこのレバー部材を閉じて押圧する。これにより、レバー部材から作動力を受けて押圧カバーが閉じ、その状態で載置部に載置された電気部品を押圧して固定するようになっていた。このとき、電気部品の各接続端子は、電気部品用ソケットの各コンタクトピンに電気的に接続するようになっていた(例えば、特許文献1参照。)。
【0004】
【特許文献1】
特許第3022593号明細書 (第3頁、第1〜3図)
【0005】
【発明が解決しようとする課題】
しかし、特許文献1に記載された技術は、押圧カバーを軸支する回転軸がソケット本体の載置部の高さよりも高い位置に配設されており、またレバー部材が押圧カバーの上面を押圧して押圧カバーに作動力を与えるようになっていたため、ソケット本体の載置部に載置された電気部品を押圧固定する押圧カバーを閉じた状態のときにその全体の高さが高かった。
【0006】
また、例えばガルウィングタイプのような接続端子の少ない電気部品を保持する電気部品用ソケットに適用されたものであって、電気部品の各接続端子に対応して設けられたコンタクトピンの本数は少なかった。そのため、レバー部材を押圧してソケット本体の載置部に載置された電気部品を押圧固定したときに各コンタクトピンの弾性変形により発生する反発力は小さく、レバー部材に大きな力を加えずに電気部品を押圧固定することができた。これに対し、例えばBGAやLGAなどの下面に多数個の接続端子が設けられた電気部品を保持する電気部品用ソケットに適用した場合には、レバー部材に大きな力を加えて押圧カバーを押圧しなければならなかった。すなわち、電気部品の接続端子数の増加に伴って、電気部品用ソケットのコンタクトピンの本数は増加する傾向にあり、この多数本のコンタクトピンの弾性変形により反発力が大きくなることがあった。したがって、多数個の接続端子を備えた電気部品を押圧固定するためには、その反発力よりも大きな力でレバー部材を押圧しなければならず、電気部品用ソケットを操作する自動機の負担が大きくなるという問題点があった。
【0007】
また、このような電気部品用ソケットに関する他の技術として、電気部品を押圧固定する押圧カバーと、閉じた押圧カバーに力を加えて固定する固定手段とを備えたものもあったが、このような電気部品用ソケットの場合には、押圧カバーを閉じる動作と、この閉じた押圧カバーに対して固定手段で固定する動作との2回の動作が必要であった。したがって、1回の動作によってレバー部材を閉じて押圧カバーで電気部品を押圧固定することができなかった。
【0008】
そこで、本発明は、このような問題点に対処し、電気部品用ソケットの載置部に載置された電気部品を押圧して固定する押圧カバーを閉じた状態のときにその全体の高さを低くすることができる電気部品用ソケットを提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するために、本発明による電気部品用ソケットは、電気部品を載置する載置部が設けられたソケット本体と、このソケット本体の一端側にて開閉可能に配設され閉じた状態で上記載置部に載置された電気部品を押圧して固定する押圧カバーと、上記ソケット本体の一端側にて開閉可能に配設され上記押圧カバーが閉じる方向に作動力を与えて閉じるレバー部材と、を有する電気部品用ソケットであって、上記押圧カバーの配設部を上記ソケット本体の載置部の高さよりも低い位置に配設し、上記レバー部材は、上記押圧カバーに設けられた操作部を押圧して作動力を与えるものとした。
【0010】
このような構成により、上記押圧カバーの配設部をソケット本体の載置部の高さよりも低い位置に配設し、上記レバー部材は、押圧カバーに設けられた操作部を押圧して作動力を与えるものとしたことで、押圧カバーを閉じた状態における電気部品用ソケット全体の高さが低くなる。
【0011】
また、上記レバー部材の配設部は、上記押圧カバーの配設部よりもソケット本体の内側に配設されている。これにより、上記レバー部材の配設部が支点となり、この配設部からの距離が遠い力点に力を加えると、配設部からの距離が近い作用点で大きな作動力を得ることができるので、レバー部材に加える力が小さいときにも、押圧カバーに大きな作動力が与えられる。
【0012】
さらに、上記押圧カバーの操作部は、その外側面の一端側と他端側の略中央部に設けられている。これにより、上記押圧カバーの操作部がレバー部材に押されて閉じられ、閉じた状態のレバー部材を押圧すると押圧カバーが電気部品の全体に均等に力を与える。
【0013】
そして、上記押圧カバーは開方向に付勢されており、上記レバー部材は押圧カバーの操作部と係合して開放されるようになっている。これにより、上記レバー部材の閉状態を解除すると、開方向に付勢された押圧カバーが開き、レバー部材が押圧カバーの操作部と係合して開放される。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態を添付図面に基づいて詳細に説明する。
図1は本発明による電気部品用ソケットの実施の形態を示す斜視図であり、図2は図1に示す電気部品用ソケットを分解した状態を示す斜視図である。この電気部品用ソケットは、図1に示すICパッケージ1などの電気部品についての性能検査を行う工程において、ICパッケージ1を着脱可能に保持して外部の測定器(図示省略)に電気的に接続する治具で、ソケット本体2と、サポートプレート3と、フローティング部材4と、押圧カバー5と、レバー部材6と、ラッチ部材7とを備えて成る。
【0015】
図1に示すソケット本体2は、ICパッケージ1などの電気部品を載置するものであって、強度が高く、かつ耐熱性に優れた樹脂によって平板状に成型されている。このソケット本体2の略中央部には、図2に示すように、ICパッケージ1を載置する載置部8が設けられており、その上面には複数本のコンタクトピン(図示せず)が取り付けられ、ICパッケージ1(図1参照)の下面に設けられた複数個の接続端子との電気的接触を図るようになっている。
【0016】
また、図2に示すように、ソケット本体2の載置部8の左右両側には固定片9が立設されている。この固定片9は、後述するサポートプレート3を位置決めするもので、ソケット本体2と一体的に成型されている。さらに、ソケット本体2の一端側(図2中における右側の一側辺)の左右両側には、第1軸受部10が設けられている。この第1軸受部10は、後述する押圧カバー5を支える支点となるもので、この押圧カバー5を軸支する回転軸となるシャフト13を通すための貫通孔10aが形成されている。このとき、第1軸受部10の貫通孔10aはソケット本体2の載置部8の高さよりも低い位置に形成されており、この貫通孔10aに通されるシャフト13は、ソケット本体2の載置部8の高さよりも低い位置に配設される。
【0017】
さらに、図2に示すように、ソケット本体2の載置部8の左右両側の所定の位置には、第2軸受部11が立設されている。この第2軸受部11は、後述するレバー部材6を支える支点となるもので、このレバー部材6を軸支する回転軸となるシャフト16を通すための貫通孔11aが形成されている。このとき、第2軸受部11は、押圧カバー5の回転軸となる第1軸受部10よりもソケット本体2の内側に配置されている。また、この第2軸受部11の貫通孔11aは、第1軸受部10の貫通孔10aと同様に、ソケット本体2の載置部8の高さよりも低い位置に形成されており、この貫通孔11aに通されるシャフト16は、ソケット本体2の載置部8の高さよりも低い位置に配設される。
【0018】
さらにまた、図2に示すように、ソケット本体2の他端側(図2中における左側の一側辺)にて載置部8の左右両側には、他の軸受部12が設けられている。この他の軸受部12は、後述するラッチ部材7を支える支点となるもので、このラッチ部材7を軸支する回転軸となるシャフト17を通すための貫通孔12aが形成されている。
【0019】
また、図1に示すように、ソケット本体2の載置部8の左右両側には、サポートプレート3が配置されている。このサポートプレート3は、ソケット本体2が変形しないように支持するもので、金属でできており、図2に示すように、ソケット本体2に設けられた左右両側の固定片9及び第2軸受部11、他の軸受部12によって位置決めされている。なお、図1に示すように、この左右のサポートプレート3は、それぞれ固定ピン19,19によってソケット本体2に固定されている。
【0020】
さらに、図1に示すように、ソケット本体2の載置部8の上方には、フローティング部材4が配設されている。このフローティング部材4は、ICパッケージ1の外側縁部を載置部8より先に受け止めるもので、ICパッケージ1を略水平状態に保持した状態で上下方向に移動可能に形成されている。このフローティング部材4の具体的な構造は、図2に示すように、載置部8の上面と略同等の大きさの枠形状を有し、その四隅部にはICパッケージ1の外側面を規制して位置決めする案内部4aが立設されている。これにより、フローティング部材4の上方からICパッケージ1を落とし込んだ際に、ICパッケージ1を所定の位置に誘い込んで受け止めることができる。また、このフローティング部材4を押圧することにより、ICパッケージ1を略水平状態に保持した状態で載置部8にまで移動して載置することができる。
【0021】
さらにまた、図1に示すように、ソケット本体2の一端側に設けられた第1軸受部10には、押圧カバー5が開閉可能に軸支されている。この押圧カバー5は、図3に示すように、閉じた状態で載置部8に載置されたICパッケージ1を押圧して固定するもので、金属で枠状体に形成され、その外側面の両側から平行に延びた左右の腕部5aの先端部には、長孔5bが形成されている。そして、この長孔5bをソケット本体2に設けられた第1軸受部10の貫通孔10aに合致させ、左右それぞれにシャフト13を通すことにより、押圧カバー5は第1軸受部10で軸支される。また、押圧カバー5の内側には、左右のシャフト14に介装された弦巻ばね15が取り付けられている。これにより、押圧カバー5は開方向に付勢されており、レバー部材6は後述する押圧カバー5の操作部20と係合して開放されるようになっている。
【0022】
また、図2に示すように、この押圧カバー5は、その外側面の両側にてその一端側と他端側の略中央部に操作部20,20を備えている。この操作部20,20は、後述するレバー部材6からの作動力を受ける作用点となるもので、その軸部の先端に鍔部が形成されている。これにより、後述するレバー部材6により押圧カバー5の外側面の両側に設けられた操作部20を押圧して閉じた状態(図3参照)のときにレバー部材6を位置決めすることができる。
【0023】
また、図1に示すように、ソケット本体2に設けられた第2軸受部11には、レバー部材6が開閉可能に軸支されている。このレバー部材6は、押圧カバー5が閉じる方向に作動力を与えて閉じるもので、金属でできており、図2に示すように、平面視でコ字形の形状を有し、その先端部6aから平行に延びた左右の腕部6bの先端部には丸孔6cが形成されている。また、この左右の腕部6b,6bは、押圧カバー5の外側面の幅よりも間隔が広く形成されている。そして、このレバー部材6の左右の腕部6bに形成された丸孔6cを、ソケット本体2に設けられた第2軸受部11の貫通孔11aに合致させ、左右それぞれにシャフト16を通すことにより、レバー部材6は第2軸受部11で軸支される。
【0024】
そして、図1に示すように、ソケット本体2の他端側(図2中における左側の一側辺)に設けられた他の軸受部12には、ラッチ部材7が回動可能に取り付けられている。このラッチ部材7は、レバー部材6を閉じたときにソケット本体2への閉状態を保持するもので、図2に示すように、レバー部材6の先端部6aを係止可能なクランプ爪7aが形成されており、その側部に形成された止め孔7bを他の軸受部12に形成された貫通孔12aに合致させ、シャフト17を通して軸支されるようになっている。また、このシャフト17にはスプリング18が介装され、ラッチ部材7が係止方向に付勢されるようになっている。
【0025】
次に、このように構成された電気部品用ソケットを使用してICパッケージ1を保持する動作について、図4〜図5を参照して説明する。まず、図4に示すように、レバー部材6及び押圧カバー5を開き、ICパッケージ1をソケット本体2の載置部8の上方に配設されたフローティング部材4の上方から矢印Cの方向に落とし込む。これにより、ICパッケージ1は、フローティング部材4の四隅部に立設された案内部4aによりその外側面を規制して位置決めされ、所定の位置に誘い込まれて受け止められる(図1参照)。
【0026】
次に、図4に示すように、レバー部材6を閉じる力を矢印D方向に加えてレバー部材6を閉じると、レバー部材6の腕部6bが押圧カバー5に設けられた操作部20を押圧し、この押圧カバー5が閉じる方向に作動力を受けて矢印Eの方向に閉じる。その後、図5に示すように、レバー部材6の先端部6aをソケット本体2の他端側に設けられたラッチ部材7で係止して閉じた状態を保持する(図3参照)。ここで、上述したように、押圧カバー5を軸支する回転軸13がソケット本体2の載置部8の高さよりも低い位置に配設されており、レバー部材6が押圧カバー5に設けられた操作部20を押圧して作動力を与えるものであるので、レバー部材6及び押圧カバー5を閉じた状態における電気部品用ソケット全体の高さを従来のものと比べて低くすることができる。
【0027】
そして、矢印Fに示すように、レバー部材6の先端部6a(力点)に力を加えて押圧する。ここで、上述したように、レバー部材6を軸支する回転軸となるシャフト16は、押圧カバー6の回転軸となるシャフト13よりもソケット本体の内側に配設されている。具体的には、図5において、閉じた状態の押圧カバー5の操作部20の右側近傍に配設されている。これにより、レバー部材6の回転軸となるシャフト16が支点となり、このシャフト16(支点)からの距離が遠い先端部6a(力点)に力Fを加えると、当該シャフト16(支点)からの距離が近い操作部20が作用点となって押圧カバー5に作動力が与えられ、この操作部20(作用点)で大きな作動力を得ることができる。これにより、レバー部材6に加える力が小さいときにも、梃子の原理により押圧カバー5の操作部20に大きな作動力を与えることができる。
【0028】
したがって、例えばBGAやLGAなどの下面に多数個の接続端子が設けられたICパッケージ1を保持する電気部品用ソケットにおいても、レバー部材6を小さい力で閉じて押圧することができ、ソケット本体2の載置部8に載置されたICパッケージ1を押圧して固定することができる。また、1回の操作で、レバー部材6を閉じると共に押圧カバー5に大きな作動力を与えることができるため、電気部品用ソケットを操作する自動機の負担を小さくすることができる。
【0029】
そして、このようにしてソケット本体2の載置部8に載置され、押圧カバー5により押圧されたICパッケージ1の保持を解除するときには、ソケット本体2の他端側に設けられたラッチ部材7に開く力を、矢印Gに示す方向に加える。これにより、レバー部材6の先端部6aの係止が外れ、開く方向に付勢された押圧カバー5が開き、レバー部材6は押圧カバー5の操作部20と係合して開放される(図1参照)。また、次のICパッケージ1を保持するときには、その次のICパッケージ1をソケット本体2のフローティング部材4の上方から矢印Cの方向に落とし込み、上述した操作を繰り返す。
【0030】
【発明の効果】
本発明は以上のように構成されたので、請求項1に係る発明によれば、ICパッケージなどの電気部品を着脱可能に保持して外部の測定器に電気的に接続させる電気部品用ソケットであって、ソケット本体の載置部に載置された電気部品を押圧して固定する押圧カバーの配設部をソケット本体の載置部の高さよりも低い位置に配設し、この押圧カバーが閉じる方向に作動力を与えて閉じるレバー部材は、押圧カバーに設けられた操作部を押圧して作動力を与えるものとしたことにより、押圧カバーを閉じた状態における電気部品用ソケット全体の高さを低くすることができる。したがって、1回のレバー部材の操作だけで押圧カバーを閉じることができ、電気部品用ソケットを操作する自動機の負担を小さくすることができる。
【0031】
また、請求項2に係る発明によれば、上記レバー部材の配設部は、上記押圧カバーの配設部よりもソケット本体の内側に配設されていることにより、レバー部材の配設部が支点となり、この配設部からの距離が遠い力点に力を加えると、配設部からの距離が近い作用点で大きな作動力を得ることができるので、レバー部材に加える力が小さいときにも、押圧カバーに大きな作動力を与えることができる。これにより、作動力の重いクラムシェルタイプの電気部品用ソケットに適用した場合でも、小さい力でレバー部材を閉じて電気部品を押圧することができる。したがって、電気部品用ソケットを操作する自動機の負担を小さくすることができる。
【0032】
さらに、請求項3に係る発明によれば、上記押圧カバーの操作部は、その外側面の一端側と他端側の略中央部に設けられていることにより、押圧カバーの操作部がレバー部材に押されて閉じられ、閉じた状態のレバー部材を押圧すると押圧カバーで電気部品の全体に均等に力を与えることができる。したがって、電気部品用ソケットを操作する自動機の負担を小さくすることができる。
【0033】
そして、請求項4に係る発明によれば、上記押圧カバーは開方向に付勢されており、上記レバー部材は押圧カバーの操作部と係合して開放されるようになっていることにより、上記レバー部材の閉状態を解除すると、開方向に付勢された押圧カバーが開き、レバー部材が押圧カバーの操作部と係合して開放することができる。したがって、上記レバー部材の閉状態を解除するだけで押圧カバーを開くことができ、電気部品用ソケットを操作する自動機の負担を小さくすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electrical component socket for detachably holding an electrical component such as an IC package and electrically connecting the same to an external measuring instrument, and more particularly, to closing a pressing cover for pressing and fixing the electrical component. The present invention relates to a socket for an electric component whose overall height can be reduced in a state.
[0002]
[Prior art]
2. Description of the Related Art Generally, when performing a performance test on an electric component such as an IC package, a socket for an electric component is used, which detachably holds the electric component and electrically connects the same to an external measuring instrument. Among conventional electrical component sockets of this type, the so-called clamshell type socket has a socket body provided with a mounting portion for mounting electrical components, and a rotating shaft provided at one end of the socket body. A pressing cover for pressing and fixing an electric component mounted on the mounting portion in a closed state pivotally supported to be openable and closable, and capable of being opened and closed by another rotating shaft provided on one end side of the socket body. And a lever member that is pivotally supported and applies an operating force in a direction in which the pressing cover closes to close the pressing cover.
[0003]
When holding an electrical component using such an electrical component socket, first open the lever member and the pressing cover, place the electrical component on the mounting portion of the socket body, and then close this lever member. And press. Thus, the pressing cover is closed by receiving the operating force from the lever member, and in this state, the electric component placed on the placing portion is pressed and fixed. At this time, each connection terminal of the electric component is electrically connected to each contact pin of the socket for the electric component (for example, see Patent Document 1).
[0004]
[Patent Document 1]
Patent No. 3022593 (Page 3, FIGS. 1-3)
[0005]
[Problems to be solved by the invention]
However, in the technology described in Patent Document 1, the rotating shaft that supports the pressing cover is disposed at a position higher than the height of the mounting portion of the socket body, and the lever member presses the upper surface of the pressing cover. As a result, an operating force is applied to the pressing cover, so that when the pressing cover for pressing and fixing the electric component mounted on the mounting portion of the socket body is closed, the entire height thereof is high.
[0006]
Further, for example, the present invention is applied to an electrical component socket for holding an electrical component having a small number of connection terminals such as a gull wing type, and the number of contact pins provided corresponding to each connection terminal of the electrical component is small. . Therefore, when the lever member is pressed to press and fix the electric component mounted on the mounting portion of the socket body, the repulsive force generated by the elastic deformation of each contact pin is small, and a large force is not applied to the lever member. The electric parts could be pressed and fixed. On the other hand, when the present invention is applied to an electrical component socket that holds an electrical component having a large number of connection terminals provided on a lower surface such as a BGA or an LGA, a large force is applied to the lever member to press the pressing cover. I had to. That is, as the number of connection terminals of the electric component increases, the number of the contact pins of the socket for the electric component tends to increase, and the repulsive force may increase due to the elastic deformation of the many contact pins. Therefore, in order to press and fix an electric component having a large number of connection terminals, the lever member must be pressed with a force larger than the repulsive force, and the burden on the automatic machine that operates the electric component socket is reduced. There was a problem of becoming large.
[0007]
Further, as another technique related to such an electrical component socket, there is a technology that includes a pressing cover that presses and fixes an electric component, and a fixing unit that applies force to the closed pressing cover to fix the closed pressing cover. In the case of such a socket for electrical parts, two operations of an operation of closing the pressing cover and an operation of fixing the pressing cover to the closed pressing cover by fixing means are required. Therefore, it was not possible to close the lever member by one operation and press and fix the electric component with the pressing cover.
[0008]
Accordingly, the present invention addresses such a problem, and when the pressing cover for pressing and fixing the electric component mounted on the mounting portion of the electric component socket is closed, the entire height thereof is set. It is an object of the present invention to provide an electrical component socket that can reduce the power consumption.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, an electrical component socket according to the present invention is provided with a socket body provided with a mounting portion on which an electrical component is mounted, and is disposed so as to be openable and closable at one end of the socket body and is closed. A pressing cover that presses and fixes the electric component placed on the mounting portion in the state described above, and is provided so as to be openable and closable at one end of the socket body, and is closed by applying an operating force in a direction in which the pressing cover closes. A lever member; and a socket for an electrical component having the pressing cover disposed at a position lower than the height of the mounting portion of the socket body, wherein the lever member is provided on the pressing cover. The operation unit is pressed to apply an operating force.
[0010]
With such a configuration, the disposition portion of the pressing cover is disposed at a position lower than the height of the mounting portion of the socket body, and the lever member presses the operating portion provided on the pressing cover to actuate the operating portion. The height of the entire electrical component socket when the pressing cover is closed is reduced.
[0011]
The arrangement portion of the lever member is arranged inside the socket body more than the arrangement portion of the pressing cover. Thereby, the disposition portion of the lever member serves as a fulcrum, and when a force is applied to a force point that is far from the disposition portion, a large operating force can be obtained at an action point that is short from the disposition portion. Even when the force applied to the lever member is small, a large operating force is applied to the pressing cover.
[0012]
Further, the operating portion of the pressing cover is provided at substantially the center of one end and the other end of the outer surface. As a result, the operating portion of the pressing cover is pressed and closed by the lever member, and when the closed lever member is pressed, the pressing cover uniformly applies a force to the entire electric component.
[0013]
The pressing cover is urged in the opening direction, and the lever member is engaged with an operating portion of the pressing cover to be opened. Thus, when the closed state of the lever member is released, the pressing cover urged in the opening direction opens, and the lever member engages with the operating portion of the pressing cover and is opened.
[0014]

[0025]
Next, an operation of holding the IC package 1 using the electrical component socket configured as described above will be described with reference to FIGS. First, as shown in FIG. 4, the lever member 6 and the pressing cover 5 are opened, and the IC package 1 is dropped in the direction of the arrow C from above the floating member 4 disposed above the mounting portion 8 of the socket body 2. . As a result, the IC package 1 is positioned by regulating the outer surface thereof by the guide portions 4a provided upright at the four corners of the floating member 4, and is guided to a predetermined position and received (see FIG. 1).
[0026]
Next, as shown in FIG. 4, when a force for closing the lever member 6 is applied in the direction of arrow D to close the lever member 6, the arm 6 b of the lever member 6 presses the operation unit 20 provided on the pressing cover 5. Then, the pressing cover 5 receives the operating force in the closing direction and closes in the direction of arrow E. Thereafter, as shown in FIG. 5, the distal end portion 6a of the lever member 6 is locked by a latch member 7 provided on the other end side of the socket body 2 to maintain a closed state (see FIG. 3). Here, as described above, the rotating shaft 13 that supports the pressing cover 5 is disposed at a position lower than the height of the mounting portion 8 of the socket body 2, and the lever member 6 is provided on the pressing cover 5. Since the operating portion 20 is pressed to apply the operating force, the height of the entire electrical component socket in a state where the lever member 6 and the pressing cover 5 are closed can be reduced as compared with the conventional one.
[0027]
Then, as shown by an arrow F, a force is applied to the distal end portion 6a (point of force) of the lever member 6 and pressed. Here, as described above, the shaft 16 serving as the rotation shaft that supports the lever member 6 is disposed inside the socket body with respect to the shaft 13 serving as the rotation shaft of the pressing cover 6. Specifically, in FIG. 5, it is disposed near the right side of the operation unit 20 of the closed pressing cover 5. As a result, the shaft 16 serving as the rotation axis of the lever member 6 becomes a fulcrum. When a force F is applied to the distal end 6a (force point) far from the shaft 16 (fulcrum), the distance from the shaft 16 (fulcrum) is increased. The operating portion 20 close to is the point of action, and an operating force is applied to the pressing cover 5, and a large operating force can be obtained at the operating portion 20 (point of action). Thus, even when the force applied to the lever member 6 is small, a large operating force can be applied to the operating portion 20 of the pressing cover 5 by the principle of leverage.
[0028]
Therefore, the lever member 6 can be closed and pressed with a small force even in an electrical component socket that holds the IC package 1 having a large number of connection terminals provided on the lower surface, such as a BGA or an LGA. The IC package 1 mounted on the mounting portion 8 can be pressed and fixed. In addition, since the lever member 6 can be closed and a large operating force can be applied to the pressing cover 5 by one operation, the load on the automatic machine that operates the electrical component socket can be reduced.
[0029]
When releasing the holding of the IC package 1 placed on the placing portion 8 of the socket body 2 and pressed by the pressing cover 5 in this manner, the latch member 7 provided on the other end side of the socket body 2 Is applied in the direction indicated by arrow G. As a result, the locking of the distal end portion 6a of the lever member 6 is released, the pressing cover 5 urged in the opening direction opens, and the lever member 6 engages with the operating portion 20 of the pressing cover 5 to be opened (FIG. 1). When the next IC package 1 is to be held, the next IC package 1 is dropped from above the floating member 4 of the socket body 2 in the direction of arrow C, and the above operation is repeated.
[0030]

Can be lowered. Therefore, the pressing cover can be closed only by operating the lever member once, and the load on the automatic machine that operates the socket for electric components can be reduced.
[0031]
According to the second aspect of the present invention, the disposing portion of the lever member is disposed inside the socket body more than the disposing portion of the pressing cover. It becomes a fulcrum, and if a force is applied to a force point that is far from the disposition portion, a large operating force can be obtained at an action point that is short from the disposition portion, so even when the force applied to the lever member is small. Thus, a large operating force can be applied to the pressing cover. Thus, even when the present invention is applied to a clamshell type electric component socket having a large operating force, the lever member can be closed with a small force to press the electric component. Therefore, the load on the automatic machine that operates the electrical component socket can be reduced.
[0032]
Further, according to the third aspect of the present invention, the operating portion of the pressing cover is provided substantially at the center on one end side and the other end side of the outer surface, so that the operating portion of the pressing cover is a lever member. When the lever member in the closed state is pressed by being pressed by the pressing member, a force can be uniformly applied to the entire electric component by the pressing cover. Therefore, the load on the automatic machine that operates the electrical component socket can be reduced.
[0033]
According to the fourth aspect of the present invention, the pressing cover is urged in the opening direction, and the lever member is configured to be engaged with the operating portion of the pressing cover to be opened. When the closed state of the lever member is released, the pressing cover urged in the opening direction opens, and the lever member can be engaged with the operating portion of the pressing cover to be opened. Therefore, the pressing cover can be opened only by releasing the closed state of the lever member, and the load on the automatic machine that operates the electrical component socket can be reduced.
