ABSTRACT:
The present invention relates to a receptacle and also a zero insertion force connector in the form of an electrical receptacle mounted within a housing. The housing is provided with an apertured cover which is movable on the housing to one position in order to bias the receptacle to an open position, allowing a male contact to be inserted through the apertured cover and into the receptacle without substantial resistance to insertion thereof. The cover is subsequently moved to a second position on the housing to release the receptacle and allow the receptacle to resiliently close and grip on the male contact, thereby electrically terminating the male contact to the receptacle within the housing. As a further feature of the invention, the receptacle is of stamped and formed configuration having a body portion with a pair of opposed gripping portions projecting therefrom. Means are provided on the body portion to distribute the resilient deflection of the spring fingers substantially along the length of the body portion, such that a gripping force is provided by the cumulative deflections of the spring fingers and the body portion together. Also the tendency for unfolding of the body portion as the spring fingers are deflected in greatly aleviated by distribution of the deflection along a substantial length of the body portion.
