Abstract
A low insertion force connector for DIP leads includes a pair of pusher rails for engaging and closing normally open receptacle contacts. The rails cooperate with a unitary, lever actuated cam. A cover retains the rails and cam stackably assembled to a housing containing the contacts. The cam has serially arranged cam surfaces, guide keys and detents which interengage various assembled parts of the connector.
Claims4
A low insertion force connector, including:
- a housing having parallel rows of contact receiving cavities, electrical contacts in said cavities having resilient receptacle portions normally open to facilitate low insertion force receipt of male electrical leads, and a manually actuated cam for closing said resilient receptacle portions onto said leads to establish electrical connections therewith, characterized in that,
- said cam includes a unitary shaft having a transverse projecting lever for rotating said shaft about an axis of rotation, one or more guide keys each projecting radially of said axis and received slidably along a respective keyway in said housing, and a series of oblong cam surfaces projecting radially of said axis,
- a pair of pusher rails slidably supported by said housing and interposed between said receptacle portions and said cam surfaces, whereby said cam surfaces are rotatable with said shaft and urge said rails slidably against said receptacle portions to close the same,
- said housing is molded with a series of integral cradles supporting said shaft, and
- a cover overlies said shaft and said rails,
- said keys, said cam surfaces and said cradles are serially arranged.
