Abstract

This article describes an improvement to existing zero insertion force (ZIF) connectors in that existing ZIF connectors, either linear or rotary, can be made to operate in a sequential manner to achieve a measure of hot pluggability.

Linear Sequencing Hot Pluggable Zero Insertion Force Connector

       This article describes an improvement to existing zero
insertion force (ZIF) connectors in that existing ZIF connectors,
either linear or rotary, can be made to operate in a sequential
manner to achieve a measure of hot pluggability.

      Referring to the figures, cassette 1 enter ZIF connector 2 and
is locked into position by rotating camming handle 3.  Logic card is
positively retained in the front and rear of the ZIF connector 2 when
a retention rod 4 engages slot 5 in the logic card 8, and cassette
slot 9 engages retention tab 10.  Pushing camming handle 3 in causes
the contacts 6 to engage the pads 7 on the logic card 8, located in
the cassette 1.  The contacts 6 can be cammed such that they engage
the card pads at selected time intervals.  This contact timing allows
the voltage and signal pins to be sequenced to the logic cards,
permitting hot plugging.  The logic card 8 cannot be powered up until
the cassette 1 is fully seated into the connector 2.  The contacts 6
are operated by the linear motion 11 of the camming handle 3.
Rotating 12, the cam handle 3 locks the cassette 1 to the connector
2.
