Abstract

634,066. Two-part couplings. CRABTREE & CO., Ltd., J. A., and MORGAN, R. W. March 30, 1948, No. 8942. [Class 38 (i)] A shuttered socket for a three-pin plug is provided with a spring k which is looped around the earth contact f<1> and controls the shutter g. The shutter comprises a plate i which has a bent-over part il to which the spring is fastened and which also has a cam m projecting into the earth contact f<1> so that it is displaced by the plug earth pin when it is inserted in the socket to slide the shutter g along grooves g<1> in the socket body, and thereby expose the live contacts f. To enhance the resiliency of the contact f<1> a spring o may be wound around it and secured to the socket body.
