Sealed cable joint box

A sealed cable joint box having two opposite ends comprising:

• a body,
• a lid for closing said body,
• a cable aperture provided at each of said ends each cable aperture at each of said ends being provided between facing end portions of said body and said lid, and being able to accommodate a plurality of cables therein,
• a first flexible and deformable seal disposed in each said cable aperture for sealing each of said plurality of cables accommodated in said cable aperture, each first seal being provided with individual cable passages for leading each of said plurality of cables accommodated in said cable aperture into said joint box,
• a peripheral groove provided along peripheral edges of one of said body and said lid, and divided into successive sections by each said cable aperture, and
• a second flexible deformable seal for peripherally sealing said joint box, said second seal being mounted in said groove, said second seal being formed of independent seal segments each received in one of said sections of said groove, and being compressed into said groove by facing peripheral edges of the other of said body and said lid when said lid and said body are joined together to form said joint box,
• wherein said seal segments in each one of said sections of said groove, have opposite seal terminal portions embedded respectively in said first seal in said respective cable aperture on both sides of said sections of said groove, and said first seal has a lower hardness than said second seal, so that said first seal in said cable aperture is compressed onto one of said seal terminal portions embedded therein to provide a continuous sealing action therewith.
