  • Patent number: 5691508
    Abstract: An enclosure (400,500) having a pair of covers fastenable together to close about and seal a cable splice between end portions of a pair of multiconductor cables. At least one routing channel (418 or 420;528) is provided at a first end (406,506) and a single routing channel (424;536) at the second end (408,508), with a splice-receiving region (454) provided adjacent inner ends of the routing channels. Axially- and laterally-staggered outermost and innermost embossments are associated with each routing channel to establish an interruption in a linear path between the cable exits and a grounding region for the multiconductor shielded cables, so that the cables must be substantially bent to course around the embossments in serpentine fashion, defining cable strain relief. A partitioned region (552) in enclosure (500) accommodates receipt of a spliced connection of a pair of single-conductor coaxial cables into a linear routing channel bypassing the grounding region for multiconductor shielded cables.

  • Patent number: 5685739
    Abstract: An electrical receptacle connector (10) including a one-piece shell (12) affixed to a housing (14) and adapted to be mounted at an input/output port of an apparatus and on a circuit board within a panel. Shell (12) includes a front wall (66) that provides shielding of the mating interface adjacent the panel cutout(s), and an upper wall (62) and a lower wall (64) extending rearwardly from the front wall (66). Retention spring arms (70,94) extend from the upper and lower walls through recesses (34,56) into plug-receiving cavities (32) to engage and retain the mating connector in a mated condition, and ground legs (96) secure the connector to a circuit board. The connector may have a pair of plug-receiving cavities (32) divided by a vertical housing wall (112), and the lower shell wall (64) may comprise two portions (84) each receivable along a slot (60) above a bottom housing wall (54) to be insulated from a circuit board beneath the connector.
