Abstract

In this zero or low insertion force connector, a member is made of plastic housing 10 including pairs of opposing contacts 12 separated by a resilient deflection member 14. Contacts 12 extend through the bottom of housing 10 where they are available for termination on a circuit card or board. A series of molded wedge-shaped members 16 is provided which activate deflection members 14 so as to force contacts 12 against module or card pins 18 inserted into housing 10 for connection to the underlying card or board 20. Pins 18 fit easily into housing 10 since there is no force applied against them until wedge element 16 contacts the deflection member 14 to cause deflection of contacts 12 into contact with pins 18 being inserted. The wedge element 16 can be part of cover 22 for housing 10.

Wedge Activated Low Insertion Force Connector

In this zero or low insertion force connector, a member is made of plastic housing 10 including pairs of opposing contacts 12 separated by a resilient deflection member 14. Contacts 12 extend through the bottom of housing 10 where they are available for termination on a circuit card or board. A series of molded wedge-shaped members 16 is provided which activate deflection members 14 so as to force contacts 12 against module or card pins 18 inserted into housing 10 for connection to the underlying card or board 20. Pins 18 fit easily into housing 10 since there is no force applied against them until wedge element 16 contacts the deflection member 14 to cause deflection of contacts 12 into contact with pins 18 being inserted. The wedge element 16 can be part of cover 22 for housing 10. Wedge members 16 are joined by end struts 24 upon which the contacting loads can be applied, for example, through the activation of screw fasteners 26. Upon release of fasteners 26, a compression spring or like device forces cover 22 including wedge member 16 into a neutral position, thus allowing removal of the module pins 18.

When pins 18 of the card or module are inserted into housing 10, the bottom of the module is flush with cover 22. When wedge element 16 is activated to cause contacts 12 to contact pins 18, cover 22 is pulled down by the screw activation thus leaving a cooling channel between the top of the cover and the bottom of...
