Abstract
A device for connecting and disconnecting connector parts, one movable and the other fixedly positioned within a housing (e.g., electronic cage). The device includes latches which are pivotedly arranged on the upper and lower corner portions of a protection structure covering a printed circuit card and flexible elements, in particular U-shaped springs, which are positioned on inflexible catch bar members which may be secured to or form part of the housing. The latches engage the flexible elements (which each include a cam member) only after a connection has been made between the mating connector parts. The initial position of the cams determines the magnitude of the insertion force needed to complete the connection. After connection has been established, the pressure occurring between the connector elements of the connected parts is largely reduced due to the ability of the cam (and flexible element) to flex, allowing the latch (and associated card) to partly withdraw away from the fixed connector (and associated board). Effective connection is thus possible between connector parts including high density numbers of contacts.
