Unipartite jack receptacle
First Claim
1. A one-piece, molded jack receptacle including front and back ends, top- and bottom-side surfaces, and a pair of cavities;
- each cavity having (i) a rectangular opening into the front end of the receptacle, (ii) a circular opening into the back end of the receptacle, and (iii) a U-shaped opening into the top-side surface, said U-shaped opening forming a cantilever whose free-end portion deflects into the cavity;
each cavity further having a non-movable retaining surface for holding an optical connector within the cavity, said retaining surface being located directly beneath the U-shaped opening.

Abstract
A one-piece (unipartite) jack receptacle 40 is molded from thermoplastic material into a generally rectangular shape to provide a compact structure for high-density optical terminations. The receptacle includes a pair of cavities 460, each having an opening in its front end, and each having an opening 422 in its back end for receiving a cylindrical alignment sleeve 440. A U-shaped opening extends from a top-side surface 415 of the receptacle into each cavity to form a cantilever 410, which may be used to hold the receptacle within a panel 200. Molded into the sidewalls of each cavity are retaining surfaces 432 for holding an optical connector within the cavity. The retaining surfaces are located directly beneath the U-shaped opening 463 to facilitate molding. Heretofore, comparable jack receptacles have been assembled from multiple parts; and this has become more costly and complex as the size of jack receptacles has decreased. In one application of the invention, a pair of the jack receptacles are joined together, back-to-back, to form an adapter 400.

7. An adapter for optical connectors comprising a pair of jack receptacles that are joined together back to back,
each jack receptacle being a unipartite structure comprising front and back ends, a pair of outside surfaces, and a row of cavities, each cavity having an opening into the front end of the receptacle for receiving an optical connector, each cavity having a boss which projects into it from the back end of the receptacle, each boss including a cylindrical passageway which opens into the back end of the receptacle, each cavity having a rigid retaining surface for interlocking with a movable latching member on the optical connector, and each cavity having a U-shaped opening into one of the outside surfaces that forms a cantilever whose free end portion is positioned toward the back end of the receptacle; -
the back end of each receptacle having a generally planar exterior surface which includes a plurality of pins and holes for aligning the cylindrical passageways when the receptacles are joined together back-to-back; and a plurality of alignment sleeves that extend between the pair of receptacles and into the cylindrical passageways. - View Dependent Claims (8)

9. A method for assembling a pair of substantially similar jack receptacles to form an adapter, each jack receptacle having a generally planar back surface which includes a cylindrical pin projecting outwardly, a cylindrical hole projecting inwardly, and an opening for receiving an alignment sleeve;
- said pin having a slightly larger diameter than the hole and a tapered distal end, the method comprising the steps of;
inserting the alignment sleeve into the opening in one of the receptacles; orienting the pair of jack receptacles, back to back, so that the pin and the alignment sleeve in one of the receptacles are respectively positioned to mate with the hole and the opening in the other of the receptacles; and pressing the receptacles together with sufficient force to cause their planar back surfaces to touch each other.
- said pin having a slightly larger diameter than the hole and a tapered distal end, the method comprising the steps of;
