ABSTRACT:
Electrical plug and socket assemblies for interconnecting electrical cables and extension cords comprising one or two piece molded bodies that form a streamlined bulbous shape when engaged. The plug and socket are engaged by pulling in substantially opposite directions and disengaged by pushing apart. The engagement of the plug with the socket thus tightens when the cables are pulled as distinguished from a conventional plug and socket. The molded plastic portions of each one or two piece plug or socket body are identical, the metal prongs or contacts being insertable during assembly to make a plug or socket respectively. The one piece body includes a hinge joining the outside female portion to the inside male portion and can be molded as one unit. The two piece body is identical except for the deletion of the hinge joining the pieces. Upon assembly of the cable and prongs or contacts into the male portion, the male portion is folded and secured into the female portion. For multiple cable connection to a single cable, a circular ring having a plurality of inwardly extending sockets and a single inwardly extending plug is provided. The configuration of the ring provides for a tightening of the engagement with a complementary plug or socket in the event of any pulling on the attached cables. The ring and optionally the plug or socket can be simply plastic molded about the metal conductors therewithin. Also disclosed are two connectors suitable for joining the new electrical plug and socket assemblies to conventional plugs or sockets.
