Abstract
(EN)
The present invention provides a pin grid array (PGA) socket (1) for electrically connecting pins (30) of an integrated circuit to a circuit substrate. The PGA socket according to the invention includes a cover (12) having insertion holes arranged in rows and columns for receiving the pins (30) of the integrated circuit and a base (10) for supporting a plurality of deflectable contacts (23). The cover (12) provides a buttress (32) extending from each insertion hole (20). The contacts (23) are preferably freely supported in the base. The cover (12) preferably provides a camming means (14). The cover (12) can be slidably attached to the base (10) to permit the cover (12) to cam over the surface of the base. When the pins (30) have been inserted through the insertion holes (20), the buttresses (32) provide support for the pins (30) of the integrated circuit as they are moved with the cover (12) to interface with the contacts (23) and while the interface between the contacts (23) and the pins (30) is maintained.
(FR)
Douille (1) à ensemble grille à broches destinée à connecter électriquement des broches (30) d'un circuit intégré à un substrat de circuit. Ladite douille à ensemble grille à broches de la présente invention comporte un couvercle (12) doté de trous d'introduction disposés en rangées et colonnes et destinés à recevoir les broches (30) du circuit intégré et une base (10) destinée à porter une pluralité de contacts (23) à déflexion. Ledit couvercle (12) comporte des contreforts (32) qui s'étendent à partir de chaque trou d'introduction (20). Les contacts (23) sont de préférence portés librement par la base. Le couvercle (12) comporte de préférence un dispositif à fonction de came (14). Il peut être fixé à la base (10) par coulissement pour permettre au couvercle (12) d'être déplacé par mouvement de la came sur la surface de la base. Lorsque les broches (30) ont été introduites dans les trous d'introduction (20), les contreforts (32) fournissent des supports aux broches (30) du circuit intégré lorsque ces dernières sont déplacées avec le couvercle (12) pour venir toucher les contacts (23) et tant que le contact entre les contacts (23) et les broches (30) est maintenu.
