Claims

1. A TERMINAL BASE ASSEMBLY OF THE TYPE MOUNTABLE UPON THE BASE END OF TRANSISTORS AND LIKE DEVICES WHICH PRESENT A PLURALITY OF LATERALLY-SPACED LEAD-WIRES PROJECTING AXIALLY FROM A BASE END-FACE IN A PREDETERMINED DISTRIBUTION PATTERN, COMPRISING:

A. A DISC-LIKE PLUG MEMBER, (1) SAID PLUG MEMBER HAVING (A) BASE AND OUTER ENDS, (B) CENTRAL AND MARGINAL BODY PORTIONS BETWEEN ITS END FACES, AND (C) A PLURALITY OF LEAD-WIRE-RECEIVING OPENENDED BORES EXTENDING AXIALLY THROUGH SAID CENTRAL PORTION FROM ONE END FACE TO THE OTHER IN A DESIRED DISTRIBUTION PATTERN, (2) SAID PLUG MEMBER BEING (A) POSITIONABLE ON SAID DEVICE WITH ITS BASE END FACE PRESSED AGAINST THE BASE END FACE OF THE DEVICE AND WITH EACH LEAD WIRE OF THE DEVICE PASSING AXIALLY THROUGH THE CORRESPONDING ONE OF ITS BORES TO PROJECT FROM ITS OUTER END FACE, AND (B) SECURABLE TO SAID DEVICE, WHEN SO POSITIONED THEREON, BY BENDING THE PROJECTING END PORTION OF EACH LEAD WIRE TO EXTEND TRANSVERSELY ALONG THE PLUG MEMBER'"'"''"'"'S OUTER END FACE;

B. A CUP-SHAPED SOCKET MEMBER, (1) HAVING A CYLINDRICAL BORE WALL, AN OPEN-MOUTH AT ITS BASE END TO RECEIVE SAID PLUG MEMBER AND A BOTTOM WALL AT ITS OUTER END, AND (2) BEING MOVABLE OVER THE PERIPHERY OF THE PLUG MEMBER (A) AXIALLY INWARD WITH ITS MOUTH END FOREMOST TO AN INNER POSITION, WHEREIN ITS CYLINDRICAL WALL ENCIRCLES, AND THE INNER PERIPHERY THEREOF FITS SNUGLY OVER, THE PERIPHERY OF THE PLUG MEMBER, AND (B) FROM SAID INNER POSITION TO AN ANGULARLY OFFSET POSITION, THIS MOVEMENT INITIALLY INVOLVING THE TWISTING OF SAID SOCKET MEMBER ROTATIONALLY OUT OF ITS INNER PLUG-MEMBERENCIRCLING POSITION;

C. BAYONET LOCKING MEANS COOPERATIVELY PROVIDED, BY THE OUTER PERIPHERY OF SAID PLUG MEMBER AND THE INNER PERIPHERY OF SAID CYLINDRICAL BORE WALL OF SAID SOCKET MEMBER, TO CONSTRAIN SAID MOVEMENT OF SAID SOCKET MEMBER OVER SAID PLUG MEMBER TO A PREDETERMINED PATH EXTENDING AXIALLY TO SAID INNER POSITION AND THENCE TO SAID ANGULARLY OFFSET OPERATING POSITION;

D. LATCHING MEANS, OPERATIVE IN SAID ANGULARLY-OFFSET OPERATING POSITION, FOR RELEASABLY LATCHING THE SOCKET MEMBER AGAINST ROTATION;

AND E. A PLURALITY OF ELECTRICAL TERMINAL MEMBERS MOUNTED ON THE SOCKET MEMBER TO PRESENT (1) A PLURALITY OF ELECTRICAL TERMINAL CONNECTIONS ON ITS OUTER FACE AND (2) A PLURALITY OF ELECTRICAL CONTACTS WITHIN THE SOCKET MEMBER, ONE CONTACT FOR EACH LEAD WIRE, (A) EACH CONTACT ARRANGED ADJACENT TO BUT SPACED FROM THE INNER BOTTOM FACE OF SAID SOCKET MEMBER IN POSITION TO BE IN ENGAGEMENT WITH ITS LEAD WIRE WHEN THE SOCKET MEMBER IS IN ITS ANGULAR OFFSET OPERATING POSITION ON THE PLUG MEMBER.
