    • 628,419. Two-part couplings. COATES, J. B., and HANKINS, M. A. June 10, 1947, No. 15297. Convention date, Dec. 31, 1946. [Class 38 (i)] A plug-and-socket coupling comprises a box 10 consisting of insulating plates 17, 18 upon which are mounted strip contacts 12, 13 secured by a partition 14, and co-operating plugs 20 provided with floating spring-loaded contacts 22, the width of the strips being such that the distance D of the strip edges from the plate edges is greater than the width L of the contacts 22, thereby preventing the operator receiving a shock during the insertion of the plug. The plug comprises an insulating body 21 provided with channels 27 apertured at 31 to allow the egress of the contacts 22 retained therein by a cover 26, the maximum body width substantially equalling the distance between the plates 17, 18. A cable housing 36 is secured over one end of the body 21 and is provided with projections 37 which engage the cable covering 24. In a modification (Figs. 4, 5, 6, not shown), the housing 36 is replaced by a clamp which is recessed within the body. In a further modification (Figs. 7, 8, not shown), fuses are inserted between the leads and the contacts which'may be formed of heavy stock or alternatively of bent strip.
