Abstract

In high density printed circuit board systems it is desirable to make the individual circuit modules pluggably insertable to facilitate the replacement and repair operations on behalf of the printed circuit boards. In order to enable the use of a no-insertion force-type module, it is essential to move the module after insertion so that the connector pins protruding from the module can be moved into contact with the contact springs of the printed circuit board.

Connector Actuation Device

In high density printed circuit board systems it is desirable to make the individual circuit modules pluggably insertable to facilitate the replacement and repair operations on behalf of the printed circuit boards. In order to enable the use of a no-insertion force-type module, it is essential to move the module after insertion so that the connector pins protruding from the module can be moved into contact with the contact springs of the printed circuit board.

The connector actuation device comprises a cap 1 adapted to support a conventional circuit module 2 having a matrix array of connector pins, not shown, protruding from the bottom of the module. The device includes levers 3 and 4 in a toggle-like arrangement wherein lever 3 is pivotally supported on a shaft 5 that is rotatably supported by the cap 1. The levers 3 and 4 are adapted to be motivated by thumbscrew 6 threaded in the top of cap 1.

The master printed circuit board 7 comprises a plurality of individual module sites with each site having a matrix array of contact springs 8 and module holding studs 9 in each corner of the site.

In the operation of inserting a module 2, the module and connector actuating device are held in a position overlying the module site on the master printed circuit board 7 and then lowered vertically into position on the board. After the module is placed on the intended site, the thumbscrew 6 is rotated so that the toggle-link arrangement of levers 3 a...
