Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A socket insulator assembly for receiving a lamp having a narrowed end from which a pair of terminals extend, the improvement comprising an insulator socket cylindrical wall having a pair of spaced axial passageways therein, an electrical receptacle in each said passageway with each receptacle having sprIng means adjacent one end for receiving said lamp narrowed end and establishing a respective electrical connection to a respective one of said terminals, a socket insulator annular wall encircling said cylindrical wall and spaced outwardly of said cylindrical wall for receiving a housing wall therebetween, means integrally joining said cylindrical and annular walls adjacent the axial ends of said socket walls opposite the position of said spring means receiving said lamp end, and integrally formed support means projecting from the end of said cylindrical wall adjacent said receptacle one end for engaging said lamp at peripheral positions intermediate the ends of said lamp for supporting said lamp against vibratory movement relative said socket.
Claim 2
Dependent Claim
160 words
A socket insulator assembly for receiving a lamp having a narrowed end from which a pair of terminals extend, the improvement comprising an insulator socket cylindrical wall having a pair of spaced axial passageways therein, an electrical receptacle in each said passageway with each receptacle having sprIng means adjacent one end for receiving said lamp narrowed end and establishing a respective electrical connection to a respective one of said terminals, a socket insulator annular wall encircling said cylindrical wall and spaced outwardly of said cylindrical wall for receiving a housing wall therebetween, means integrally joining said cylindrical and annular walls adjacent the axial ends of said socket walls opposite the position of said spring means receiving said lamp end, and integrally formed support means projecting from the end of said cylindrical wall adjacent said receptacle one end for engaging said lamp at peripheral positions intermediate the ends of said lamp for supporting said lamp against vibratory movement relative said socket.
Claim 3
Dependent Claim
50 words
In the socket assembly claimed in claim 1, a housing having an annular wall for receipt between said socket cylindrical and socket annular walls with the diameter of said housing annular wall dimensioned for encircling engagement with said projecting support means to assist in preventing vibratory movement of said lamp.
Claim 4
Dependent Claim
94 words
The socket assembly claimed in claim 2 in which said insulator socket has a plurality of radial lugs integrally formed between said insulator socket cylindrical wall at a position spaced axially from said means joining said socket cylindrical and annular walls, a plurality of J slots formed at one end in said housing annular wall with each J slot receiving a respective radial lug, and a plurality of stop walls formed on said socket for engaging said housing wall one end and cooperating with said radial lugs for restraining vibratory movement of said housing.
Claim 5
Dependent Claim
27 words
In the socket assembly claimed in claim 3, a spring clip on said housing spaced from said housing one end for engaging said housing with a support.
Claim 6
Dependent Claim
48 words
In the socket assembly claimed in claim 4 in which said integrally formed support means comprises a plurality of circumferentially spaced arcuate walls projecting from said socket cylindrical wall along an inner diameter of 0.40 inch and substantially the same diameter as the outer diameter of said lamp.
