Claim 1

An electrical contact for connection to the end portion of a conductor of a wire, comprising: a trough portion arranged to receive said conductor end portion and including a pair of side walls and a bottom wall, a pressure strip extending longitudinally along said trough portion in upwardly spaced relation to said bottom wall for overlying the length of said conductor end portion and for movement toward said bottom wall to press said conductor end portion between said strip and said bottom wall, said strip having a width large enough to provide openings between it and said side walls which are smaller than the diameter of said conductor end portion, a fastener having a terminal end for engagement with a portion of said strip which is intermediate said one end thereof and an opposite end thereof for moving said strip toward said bottom wall, and a fastener support for supporting said fastener from said trough portion, said trough portion, pressure strip and fastener support being formed as integral parts of a single element of sheet metal, said element including a strip-support section extending from one of said side walls of said trough portion toward the other of said side walls of said trough portion and over said pressure strip with said pressure strip having an end connected through a 180 degree bend to one end of said strip-support section, said strip-support section having an opening therein through which said fastener element extends, and said fastener-support being in the form of a section of said element of sheet metal extending from the upper edge of said other of said side walls of said trough portion toward the upper edge of said one of said side walls of said trough portion in overlying relation to said strip-support section.
