It will be noted that at the center portion of the base |22, there is provided a structure |50 30 prevent displacement thereof during installation having vertical side walls provided with upstand in a vertical plane. ing lugs, |5|, |5|. Such structure |53 has pas The grooves 24 in the transverse walls 23 of sages l52, |52 therethrough, said passages ter base 22 and the similar grooves in end walls 23a minating in polygonal pockets |53 into which the of cap 2B register with the intersection of the nuts of the screw-nut assemblies 40 snugly and vertical and horizontal walls of the angle-form 35 conductors 33; and the base grooves guide the conductors 2i) of an adjacent unit into preferred position for securernent to the conductors 33. Optional means are provided for the mechani cal interconnection of adjacent units and'for the securement of a run of units to the wall of a roem. According to the embodiment of Figures 1 through 3, mechanical interconnection of ad jacent units, additional to the connection afforded frictionally ñt. Electrical interconnection between conductors 33 of like polarity may be made by the conductors |54, clamped to said conductors in the same man ner as are the conductors 20, see Figure 2. Arrangedto iit over and enclose the structure |50 and the electricity conductors |54 on each side thereof, is a sheath |55, which may be of rela tively thin insulation material such as molded fiber. Said sheath |55 has openings |55, |56 by the clamping means, is effected by a machine 45 therethrough, said openings receiving and engag screw and nut 4|), which pass through register ing with the lugs |5| of said structure |50 to ac ing openings in the eave 21 of the cap 2S and curately position the sheath and prevent lateral the extension 2| of a unit I5.

The molding strip I5 fully conductors 20 thereof guided into position beneath conceals such upper wing 4H) and its screw the clamps 38 by the grooves 24. The clamp fastening. , ' screws may then be tightened up and after a sec Referring to Figures 3 nd 4, it will be noted ond run unit |Il has been similarly placed in posi that the base 22 of connector unit I2 is formed tion, the cover member of the connector unit I2 with extending lugs 42, over which fingers 43 of may be iitted over the assembly and made secure 70 the clips 4| iit in gripping relation therewith. by the screw and nut organization 40 at each end The extent of outward projection of the lugs 42, plus the thickness of the ñngers 43, equals the width of the cap member 2S, whereupon the unit with its assembled clips 4| is without break or offset which would interfere with the positioning 75 thereof. ' It is seen, therefore, that the installation of this wiring >system is exceedingly simple, in that all operations of connection, etc., are made from the 5 2,408,442 front and in full view of the installer. The clamp ing means 38, engaging the conductors 20 at twoy relatively Widely spaced points, and urgingr said conductors into contact with the conductors 33 at the juncture of the angle-'forming walls there of insure proper electrical interconnection of the respective units.
