Publication number: 20080232741Abstract: A connector receptacle comprises a housing having a forward mating end and a rear end, with an internal surface provided within the housing facing toward the rear end. The internal surface comprises at least a one alignment structure to engage and thereby maintain one or more optical elements in horizontal and vertical alignment. A clip having at least one retention mechanism engages complementary features on the housing to thereby retain the clip in fixed alignment with the housing. The clip also comprises at least one resilient member to bias the at least one optical element into mating engagement with the one or more alignment structures. Where the housing and clip are fabricated from electrically conductive materials, the clip may comprise one or more corresponding continuity pins to be received in continuity slots of the housing. Features of the clip to accommodate either surface mounting or through-hole mounting configurations are provided.Type: ApplicationFiled: March 22, 2007Publication date: September 25, 2008Applicant: MOLEX INCORPORATEDInventors: Barbara Grzegorzewska, Ilya Makhlin, Thomas R.

Publication number: 20070036489Abstract: An interconnect system includes a transceiver module assembly that is mountable in an industrial receptacle. The receptacle mates to an industrial optical connector to form an environmentally sealed connection. The receptacle has an interior passageway and mating means for attaching the module assembly. The module assembly includes a spring-loaded module cage for receiving active devices, such as SFP transceivers. The spring-loaded module cage can adjust its position within the receptacle to accommodate different type of modules from various vendors. When attached to the platform, the module assembly is positioned so that the cage's open end is accessible through the receptacle's passageway. Users have the option of plugging/unplugging the transceiver module either through the passageway or by removing the module assembly from the receptacle.Type: ApplicationFiled: August 15, 2005Publication date: February 15, 2007Inventors: Barbara Grzegorzewska, Thomas R.
