Abstract

A cable splice enclosure (10) including a pair of cover members (12,14 ) joined along a flexible hinge (62,64) and rotatable together about the hinge to enclose a cable splice (150) and secure to each other with latches along both side edges (16,18;92,94 ). Sealant material (120) disposed within central regions (32,34) of both covers environmentally seals the surfaces of the splice connection (154,158,160) upon full closure. Embossments (44,46 ) on both sides of the cable-receiving channels (20,22) in associated pairs (40,42,48) proximate the cable exits include resilient flange portions (52,54) cooperate to press into the cable insulation upon full closure to define a strain relief. The enclosure (200) may be used to splice aerially suspended cable (202) by grooves (208) between the hinge (216) and the latches (218) proximate the hinge (216), receiving thereinto a length of suspension wire (206) spliced to suspension wire (204) thus securing enclosure (200) to cable (202).

Claims

1. An enclosure of the type having first and second cover members securable together along mating faces thereof, comprising:

first and second cover members molded of resilient material in a single piece, joined to each other along adjacent side edges by a flexible living hinge portion, and include integral complementary latching members along remote side edges that are engageable upon closure of the cover members, thus fully securing together at said mating faces without other fastening means, and further include integral complementary latching members along said adjacent side edges, said cover members containing integral securing means for assuredly securing to each other along opposed side edges thereof.

2. An enclosure as set forth in claim 1 wherein said first and second cover members include opposing axially extending flange portions along said adjacent side edges between said hinge portion and complementary latching members therealong, and said flange portions of at least one of said cover members define a groove into a surface thereof facing the opposed flange portions, whereby a suspension wire length is receivable into said groove when said enclosure is in an open position and is held therein upon closure of said enclosure, thereby being adapted to be used with aerially suspended cable at a splice thereof.

3. The enclosure as set forth in claim 1 wherein said first and second cover members include upstanding wall portions and complementary wall-receiving regions along said adjacent and remote side edges inwardly of said complementary latching members, each of said upstanding wall portions having a leading end adapted to bear against a complementary surface of a corresponding one of said complementary wall-receiving regions during closure of said first and second cover members, bounding a central region of said cover members for retention of sealant material therewithin.

4. An enclosure as set forth in claim 3 wherein one of said upstanding wall portions is defined along one of said adjacent and remote side edges of each of said first and second cover members and one of said complementary wall-receiving regions is defined along the other thereof, all complementary to the other of said first and second cover members.
