Cable sealing device for an electrical junction box

An electrical junction box for a vehicle, comprising:

• a box having walls defining an enclosed interior space and a door allowing access to the interior space, one of said walls having a hole;
• a centering frame mounted at the hole in the wall, the centering frame including a first rim extending perpendicular to an exterior surface of the wall, a flange extending parallel to the wall within the first rim and defining a central opening, and a second rim extending perpendicular to an interior surface of the wall;
• a first clamping plate having a plurality of cable passage holes and having a post extending from a surface thereof, the first clamping plate being disposed on a first side of the centering frame within the rim and with the post extending through the central opening;
• a second clamping plate having an equal plurality of cable passage holes and a centrally-located aperture to receive the post, the second clamping plate being disposed on a second side of the centering frame opposite the first side with the post received in the aperture and wherein the cable passage holes of the first clamping plate are aligned with the cable passage holes of the second clamping plate to define a plurality of cable passages;
• and,
• a sealing membrane disposed between the first clamping plate and the flange of the centering ring, wherein the sealing membrane has a centrally-located aperture to receive the post, wherein portions of the sealing membrane are exposed at the plurality of cable passages and wherein at least one exposed membrane portion has a perforation to accept a cable.
