る。The IC is attached to the cover 7 from a pair of opposing left and right edge plates 7b.
A plurality of hook-shaped locking pieces 8 facing the connection board 3 are lowered, and engagement grooves 9 for inserting and removing the hook-shaped locking pieces 8 are provided on the left and right side surfaces of the connection board 3, and the retaining grooves 9 are arranged as described above. The hook-shaped locking piece 8 is dimensioned so that it can move laterally in the direction of the contact implantation row within the engagement groove 9, thereby allowing the cover 7 to move in the same direction, and the engagement groove 9 A hook-shaped stepped portion 10 is formed at one end of the cover 7 to receive and engage the locking claw piece 8a of the locking piece 8 when the cover 7 is moved laterally. It is moved laterally between the opening stop position and the opening stop release position, and when it is moved laterally to the opening stop position, it is in the locked state (locking claw piece 8a
and the hook-shaped stepped portion 1o are formed, and the lock is released by lateral movement to the opening stop release position, and removal becomes possible.

The cover 7 is mounted in such a way as to allow the cover 7 to move laterally by itself, such as by sliding the mount 11a onto the edge of a long hole 12 drilled in the top plate 7a.

これによってカバー７は単独で上記開き止め解除位置か
ら開き止め位置へ横移動され、この間端子押さえパッド
１１は横移動せず前記接触押さえを保持する。As a result, the cover 7 is independently moved laterally from the opening stop release position to the opening stop position, and during this time, the terminal holding pad 11 does not move laterally and holds the contact holding down.

定且つ高信頼の接続が果される。Further, according to the present invention, the contact between the IC external terminal 2 and the contact 4 can be maintained well by the terminal holding pad 11 by simply covering the cover 7 and moving it laterally to the opening stop position, thereby achieving a stable and highly reliable connection. fulfilled.

カバー７は端子押さえパッド１１と端子２の接触抵抗の
影響を受けず円滑に開き止め位置へ横移動させることに
よって、ＩＣ接続盤３と一体に組付けられ、端子押さえ
パッド１１の浮上りを防止し端子押さえ面の密着を保持
することができる。The cover 7 is assembled integrally with the IC connection board 3 by smoothly moving laterally to the opening stop position without being affected by the contact resistance between the terminal holding pad 11 and the terminal 2, thereby preventing the terminal holding pad 11 from floating up. It is possible to maintain close contact with the terminal holding surface.

カバー７は回動可に取付けて、開閉させる方式と異なり
、開閉のためのデッドスペースを要せず、ＩＣ外部端子
２の面と平行且つ均一な接触圧で接触させることができ
る。Unlike a method in which the cover 7 is rotatably attached and opened and closed, no dead space is required for opening and closing, and the cover 7 can be brought into contact with the surface of the IC external terminal 2 parallel to and with uniform contact pressure.

前記の如くカバー７はパッド１１を追随動させず、単独
で開き止め位置と同解除位置に横移動できる。As described above, the cover 7 can independently move laterally to the opening stop position and the release position without causing the pad 11 to follow the movement.

従ってカバー７の横移動にてパッド１１がＩＣ外部端子
２をこすり同端子２を横方向へ偏位させピッチに不揃い
を招来したり、又コンタクト４を引掛けて偏位又は変形
させたりする恐れがなく、接触部を上から押さえ込んだ
静的状態を確保し接触を正常に保持する。Therefore, when the cover 7 moves laterally, the pad 11 may rub against the IC external terminal 2, causing the terminal 2 to be displaced laterally, resulting in uneven pitch, or may catch the contact 4, causing it to become displaced or deformed. This ensures a static state where the contact part is pressed down from above and maintains normal contact.

上記工夫によってカバー７を横移動方式として適切なる
接触押さえを図る機構の実用が支障なく果せ、薄形化等
に寄与する。With the above-mentioned device, it is possible to put the cover 7 into practical use without any hindrance in order to achieve proper contact and pressure by moving the cover 7 laterally, and this contributes to a reduction in the thickness of the cover.
