ABSTRACT:
An electrical connection assembly for use at a firewall bulkhead for connecting the electrical conduits coming from one side of the firewall with those coming from the other side. A main connection panel has a unitary body of insulating material with a series of rows of through openings between its faces. In each opening is metallic tubular first insert having, between the faces, in interiorly threaded portion and a radially inset smooth-walled portion. A set of connector plugs, each different in outline from the other and each having at least one row of through openings spaced to match a corresponding row on the panel, fits against and is keyed to the panel, so that each plug can occupy only one possible position, aligning the openings. In each of these openings is a tubular, interiorly threaded second insert. Solid electrical binding posts include a set for the panel, each having a portion threaded into the interiorly threaded portion of each first insert, and a connector-clamping head. In a set for the plugs, the binding post has a clamping head, a threaded shank threaded into each second insert, and an extension projecting out beyond the plug and extending into and in electrical contact with the smooth-walled portion of a first insert. A cover plate helps to hold the plugs in place against vibration.
