Abstract

1290596 Electric couplings BULPITT & SONS Ltd 26 April 1971 [22 April 1970] 19159/70 Heading H2E A method of making an electrical connection between an electrical lead 6 and a terminal 1 having a hole 2 with an enlarged mouth 3 comprises the steps of inserting the lead in the hole, placing in the mouth an electrically conductive collar 5, applying axial pressure to the collar to urge it against a shoulder 4 thus deforming the collar, which is malleable, and causing it to grip both the lead and the inside of the hole. The mouth 3 may also be deformable and be compressed after the collar has been positioned. Before the application of axial pressure the collar is in the form of a dished washer (Fig. 1, not shown). The collar may be larger than that shown in Fig. 2, in which case part of it is deformed into a tubeshaped portion which grips the lead. In another embodiment (Figs. 3 and 4, not shown) the collar is in the form of a tapered tubular rivet. In a further embodiment (Figs. 5 and 6, not shown) the terminal mouth 3 is frusto-conical and the collar is in the form of a tubular rivet with an annular flange (7). The lead may be soldered to the terminal at the mouth 3 in which case the collar prevents flow of solder into the rest of the hole 2.
