ZERO INSERTION FORCE ELECTRICAL CONNECTOR

摘要

The connector has an insulating housing (10) having a channel (18) for receiving a circuit board (not shown). A cam follower (14) is movable by a cam (12) between a first position in which contact springs (50) of terminals (16) in the housing (10) are in an open position in which the circuit board can be inserted into the channel (18) with substantially zero insertion force and a second position in which the contact springs (50) are in a closed position so as to engage the circuit board. To ensure that the cam follower (14) is positively returned to its second position and is not subject to unintended movement therefrom, e.g. as a result of vibration, the cam follower (14) has a hooked extension (40) which is engageable by the cam (12) to return the cam follower (14) and to secure it in its second position.
