Rotary zif connector edge board lock

摘要

A locking device is disclosed for use in combination with a known rotary cam, zero insertion force edge board connector. The locking device insures that a board will be correctly positioned in the connector before the contacts of the connector can be actuated into engagement with the board and prevents the board from being removed axially once it is in place. The subject locking device is particularly useful in instances of tandem edge board connectors when one of the series is in a relatively remote and/or inaccessible position. The subject locking device rotates with the rotatable cam actuating means of the connector and prevents rotation of the cam unless the board is properly positioned. The locking device can serve either as the driving member for the rotary cam or be rotated by the cam.
