Directional electrical heating panel assembly

Claim 1

An electrical heating panel assembly comprising at least two relatively thin and generally planar panels arranged in face-to-face relationship and in inner-outer relationship relative to a zone to be heated thereby, means securing said panels together, said inner panel carrying a length of electrical resistance heating wire and a pair of cold leads connected with the heating wire and projecting outwardly from the panel face, said outer panel having a through opening receiving said cold leads, a junction box mounting plate having a portion thereof arranged in and substantially fitting the wall of said through opening and having a marginal flange disposed between said panels adjacent said opening, said marginal flange and mounting plate being held firmly in position by entrapment of the flange by and between said panels and said means securing the panels together, and said mounting plate having a through opening in said portion which is arranged in the panel opening and through which said cold leads pass, a junction box associated with said mounting plate and having an opening for receiving said cold leads, means detachably connecting said junction box to said mounting plate with the box projecting outwardly from said outer panel and with the opening therein in communication with the mounting plate opening, said junction box and mounting plate when so connected electrically isolating said outer panel from the interior of the box and plate, power line entry means in said junction box for the introduction of at least a portion of a power supply line to the interior of said junction box for insulated electrical connection with said cold leads therewithin, an access opening at a top portion of said junction box opposite said cold lead opening, and a cover for said access opening in said junction box.
