Abstract
Abstract The lamp string L (FIG. 4) has a series of identical socket assemblies A (FIGS. 1 and 2) each including a rubber case C cast about a standard screw socket S. A bulb cage B (FIG. 4) is carried on a ground ring R. The ground ring R is closely located about the socket S and positioned to shield the socket S from destructive forces. Grooves G and H trap moisture.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
A lamp string including a series of spaced socket assemblies, each socket assembly including at least one thin-walled screw socket having a base at one end and an opening at the other; a case partially encapsulating said socket and providing access to the opening of said socket; and a ground ring made of conductive material and located in a closely spaced circumscribing relationship to said screw socket and partially encapsulated by said case, and with the material of said case extending through the substantially circular space between the ring and the socket, said circular space having an outer diameter defined by the inner diameter of the ground ring and having an inner diameter defined by the outer diameter of said screw socket, the ratio of said outer diameter of said space to the inner diameter of said space being not more than about 3/2, said ring having an axial length not less than about half the axial length of said socket, said case exposing peripheral portions of said ground ring for attachment of the clamp or other base of a bulb cage whereby said ring serves to shield said socket while serving as a protective grounding device.
Claim 2
Dependent Claim

A lamp string including a series of spaced socket assemblies, each socket assembly including at least one thin-walled screw socket having a base at one end and an opening at the other; a case partially encapsulating said socket and providing access to the opening of said socket; and a ground ring made of conductive material and located in a closely spaced circumscribing relationship to said screw socket and partially encapsulated by said case, and with the material of said case extending through the substantially circular space between the ring and the socket, said circular space having an outer diameter defined by the inner diameter of the ground ring and having an inner diameter defined by the outer diameter of said screw socket, the ratio of said outer diameter of said space to the inner diameter of said space being not more than about 3/2, said ring having an axial length not less than about half the axial length of said socket, said case exposing peripheral portions of said ground ring for attachment of the clamp or other base of a bulb cage whereby said ring serves to shield said socket while serving as a protective grounding device.
Claim 3
Dependent Claim
105 words
The combination as set forth in claim 1 in which three insulated wires extend uninterruptedly through said case, said wires having a common jacket, a portion of which within the case is removed; and three jumper wires all in the case, one of the jumper wires electrically joining one of the through wires to the ring, the other of the two jumper wires joining parts of the socket to the other two through wires; said jumper wires each carrying clamps at one end constricted to bared portions of the respective through wires, said bared portions as well as said clamps being encapsulated by said case.
Claim 4
Dependent Claim
70 words
The combination as set forth in claim 1 in which said case at the region of access to said socket opening is resilient and flexible sealingly to engage the neck of the lamp bulb installed in said socket, said case having internal groove means for trapping moisture at the said lamp neck and forming closed circuitous channel means with the lamp neck at a place located outwardly of the socket.
