ABSTRACT:
A plug is coupled to a receptacle by means of a projecting rim on the base of the plug which engages a flange of the receptacle. The receptacle contains at least two electric current conductors extending in a longitudinal direction. Contact pins in the plug are mounted on a contact pin support which is spring loaded in the plug housing. The housing base can be inserted in the receptacle when the housing is oriented transverse to the longitudinal direction. Supporting blocks on the contact pin support then engage the flanges on the receptacle to cause the pins to recess in the housing against the spring forces. Upon rotating the housing 90.degree., the projecting rim of the base engages the flanges of the receptacle and the supporting blocks enter the receptacle, due to the springs, causing the contact pins to engage the current conductors.
