Abstract

A telecommunications enclosure is provided with reliable sealing around cables entering therein. The enclosure includes one or more cable ports with cable seals made from a material that includes an oil-bleed silicone rubber. The cable ports may also have a convoluted or serrated inner surface configured to engage and support the cable seals.

Claims

1. A telecommunications enclosure comprising:

a housing including first and second housing pieces that meet at a sealed perimeter interface, the housing defining a cable port having a first half-portion defined by the first housing piece and a second half-portion defined by the second housing piece, the cable port including a plurality of annular projections separated by annular grooves;

a latch arrangement for securing the first and second housing pieces together; and

a cable seal that fits in the cable port, the cable seal defining a cable passage for receiving a cable, the cable seal being made from a material that includes oil bleed-out silicone rubber, wherein when the first and second housing pieces are secured together by the latch arrangement the cable seal is pressed between the first and second half-portions such that the annular projections circumferentially compress the cable seal causing outer portions of the cable seal to elastically deform into the annular grooves and store elastic energy therewithin, the annular grooves being sized such that the annular grooves are only partially filled by the outer portions of the cable seal.

2. The telecommunications enclosure of claim 1, wherein the sealed perimeter interface is sealed with a thermoplastic gel.
