Telecommunications enclosure with cable seal
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.
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 projections separated by a plurality of grooves, the plurality of projections and the plurality of grooves being provided at least partially annularly on an inner surface of the cable port;
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, 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 plurality of grooves and store elastic energy therewithin, the plurality of grooves being sized such that the plurality of 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.
3. The telecommunications enclosure of claim 1 , wherein the cable seal defines a plurality of cable passages for receiving a plurality of cables, respectively.
4. The telecommunications enclosure of claim 1 , wherein the cable seal has a plurality of grooves in an outer portion thereof.
