【従来の技術】従来の薄形のＩＣチップ用のソケットの
一例として、図４、５に示すものがある。このソケット

すると共に、接触部１２ａがＩＣチップ１５の電極部に
対して弾圧接触することで電気的接続が行われる。2. Description of the Related Art An example of a conventional socket for a thin IC chip is shown in FIGS. In this socket, a large number of contact pins 12 are integrally attached to a socket body 11 by a so-called insert forming method. The IC is placed on the contact portion 12a of the contact pin 12.
The chip 15 is placed and the cover 19 is attached to the socket body 11. In this state, the contact pin 12 is elastically deformed, and the contact portion 12a is elastically contacted with the electrode portion of the IC chip 15 to establish electrical connection.
【０００３】しかし、このＩＣソケットではコンタクト
ピン１２の弾性に抗してカバー１９を装着しなければな
らないので、１本のコンタクトピン１２の弾性は小さく
ても、本数が多くなるとカバー装着時に多数のコンタク
トピン全てを小さなストロークで一気に押すことにな
り、カバー１９の装着作業が大変である。However, in this IC socket, since the cover 19 must be mounted against the elasticity of the contact pins 12, even if the elasticity of one contact pin 12 is small, if the number of the contact pins 12 is large, a large number of them will be attached when the cover is mounted. Since all the contact pins are pushed at once with a small stroke, the work of mounting the cover 19 is difficult.
【０００４】又、ソケット本体１１やカバー１９の強度
が充分でないと撓みを生じ、その分コンタクトピン１２
の接触圧が小さくなり、接触不良となる。特に高温での
環境下ではソケット本体１１の合成樹脂が応力緩和を起
こすため、更に撓みを大きくしてしまう。If the strength of the socket body 11 and the cover 19 is not sufficient, bending occurs, and the contact pin 12 is correspondingly bent.
The contact pressure is reduced, resulting in poor contact. Particularly in an environment of high temperature, the synthetic resin of the socket body 11 causes stress relaxation, which further increases the bending.
【０００５】更に、ＩＣチップ１５はソケット本体１１

ピン１２と接触する虞があるときに、各コンタクトピン
１２を仕切る仕切壁を設けることが難しい。Further, the IC chip 15 is the socket body 11
Since it is positioned by, the so-called wiping action is small. In addition, when the contact pins 12 are closely spaced and there is a risk that the contact pins 12 may deform and come into contact with the adjacent contact pins 12, it is difficult to provide a partition wall for partitioning the contact pins 12.
【０００６】その上、コンタクトピン１２が細かくなる
と、コンタクトピン１２の弾性が弱くなり、希望の接触
圧が得難く、コンタクトピン１２も永い間使用している
と永久変形を起こし易い。In addition, when the contact pin 12 becomes fine, the elasticity of the contact pin 12 becomes weak and it is difficult to obtain a desired contact pressure, and the contact pin 12 is likely to be permanently deformed if it is used for a long time.

When standing up with the extending piece 22g, the contact portion 22 during standing up
b is elastically pressed by the inclined portion 21c of the contact pin 21 to maintain the standing state, and the rotating cam 22 is completely retracted from the IC pitch insertion region. Moreover,
The sloped portion of the rib 22h having the horizontal contact portion 22c can also be used as a guide when the IC chip is inserted.

１５を下側に押圧することになる。Next, the IC package is placed on the contact portion 21b of the contact pin 21 while being guided by the rib 22h. In this state, the extending piece 22g of each rotating cam 22 is operated with a finger to bring the rotating cam 22 into a horizontal state. In such a state, the rotation cam 22 is in the elastically clamped state between the rotation center groove 22a and the horizontal contact portion 22c between the rotation fulcrum 21h of the contact pin 21 and the inclined surface 21c.
In this case, since the horizontal contact portion 22c is located outside the rotation center groove 22a, the rotation cam 22 is elastically pressed so that the pressing portion 22e is pressed downward, and as a result, the IC chip 15 is lowered. It will be pushed to the side.

By dividing, the operation of the rotating cam 22 becomes easier, and the number of contact pins can be further increased. Further, although the extending piece 22g is arranged at the central portion of the rotating cam 22 in the drawings of the above-mentioned embodiments, it may be arranged at both end portions or in the vicinity thereof.

【００３７】回動カム２２は全長にわたって同じ角度だ
け回動することが可能であるので、捩が発生せず、従っ
てコンタクトピン２１は両端部と中央部とで完全に同じ
形状で変化する。このため、コンタクトピン２１の数を
増やすことが可能である。Since the rotary cam 22 can rotate by the same angle over the entire length, no twist is generated, and therefore the contact pin 21 changes in exactly the same shape at both ends and the center. Therefore, it is possible to increase the number of contact pins 21.
