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.

Claims

1. An enclosure for being secured about a splice connection of a pair of electrical cables and having opposed first and second cover members adapted to be secured to each other about the splice connection to define the enclosure therearound, said enclosure comprising a splice-receiving region between opposed ends of said enclosure, said first cover defining at least one routing channel extending to said splice-receiving region from a respective cable entrance at each of said opposed enclosure ends, said first cover including at least two embossments spaced inwardly from said enclosure ends and along said routing channel and extending inwardly from respective inner cover surfaces, and said embossments being so positioned to require that said cables inserted therealong must be bent sequentially at two spaced locations and toward opposite sides of said first cover to pass by said embossments during cable insertion to extend between respective said cable entrances and said splice-receiving region, said routing channel thereby being serpentine and said cables being bent around said embossments defining a cable strain relief.

2. The enclosure as set forth in claim 1 wherein said embossments extend to free ends dimensioned and positioned to meet embossment free ends of said second cover member upon closure of said enclosure about said splice connection.

3. The enclosure of claim 1 wherein said enclosure includes a partitioned section extending between cable exits at said opposed ends of said enclosure, defining a cable-receiving channel isolated from a ground region for receipt therealong of an additional cable length.

4. The enclosure of claim 3 wherein said cable length includes a spliced interconnection between two cable ends.

5. The enclosure of claim 1 wherein a cable-gripping member is affixed to said first cover member at a location centrally of said enclosure ends, and said cable gripping member includes at least two cable-receiving slots defined in at least one wall section thereof generally parallel to said enclosure ends so that said cables received into said slots must be oriented generally parallel to said first cover sides, and innermost ones of said embossments along said routing channel are laterally offset in a selected direction from said cable receiving slots and remote from one of said first cover sides necessitating said cables to be bent around said innermost ones of said embossments in order to align said cables with associated said cable receiving slots, thereby enhancing said cable strain relief of said enclosure.

6. The enclosure of claim 1 wherein a ground contact is affixed to said first cover member at grounding region adjacent said splice-receiving region for engaging and electrically connecting to shield members of said cable pair, with said ground contact including a pair of cable-receiving slots each aligned to receive a respective one of said cables thereinto, and said grounding region is positioned adjacent a first one of said first cover sides and said first cover member generally surrounds said grounding region with upstanding wall sections, with transverse ones of said wall sections being positioned adjacent and along outer surfaces of plate sections of said ground contact and having cable openings thereinto aligned with said cable-receiving slots of said ground contact, and innermost ones of said embossments along said routing channel are laterally offset in a selected direction from said cable openings and remote from said first one of said first cover sides necessitating said cables to be bent around said innermost ones of said embossments in order to align said cables with associated said cable openings, thereby enhancing said cable strain relief of said enclosure.

7. The enclosure of claim 6 wherein said routing channel extends from an associated said cable entrance at from about 40°

to about 70°

toward a second one of said first cover sides from a direction parallel thereto until reaching one of said innermost embossments associated with said routing channel, and then extends from said innermost embossment at from about 40°

to about 70°

toward said first one of said first cover sides from said parallel direction, until reaching a position adjacent and aligned with a respective one of said cable openings of said grounding region wall sections.

8. The enclosure of claim 6 wherein said enclosure includes an additional routing channel coextending from an additional respective cable entrance at a first of said enclosure ends, whereby said enclosure is adapted to receive end portions of two of said cables either both entering said first enclosure end in a parallel cable routing arrangement, or each entering a respective one of said first end and a second of said enclosure ends in an in-line cable routing arrangement.
