Abstract
Abstract A connector for making high voltage connection to an anode button on a display device such as a cathode ray tube which permits ready disconnection at the button features a receptacle which is designed for mating with an appropriate lead assembly having a contact pin socket. An elongate male contact pin having a screw head at one end and being threaded adjacent the same end has a snap-in piece having spring fingers arranged in a circular pattern for engaging the interior portion of the anode button fixedly positioned on the pin in abutting relation with the screw head by a nut threadably engaging the threaded portion of the pin. A receptacle has an externally threaded tubular end portion and a reduced axial opening in one end which is internally threaded for receiving the contact pin in threaded engagement so that the pin end extends into the tubular portion for engagement with the pin socket of the mating piece, and the screw head and spring fingers are positioned outside the receptacle for being engaged with the anode button so that by tightening the receptacle on the threaded contact pin, the spring fingers are forced into positive locking engagement with the button. A wide circumferential flange on the receptacle compresses an O-ring sealing member against the glass surface of the display tube about the anode button upon tightening of the receptacle on the threaded contact pin.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A connector for making high voltage connection to an anode button on a display device comprising: a receptacle designed for mating engagement with an appropriate lead assembly having a tubular end portion, a wide external flange on the tubular portion adjacent one end thereof closing the tubular opening at said one end, and a threaded axial opening in said flange of substantially smaller diameter than the diameter of the tubular opening; and a contact assembly threadably engageable with said threaded opening in said flange and having spring engaging means for engaging an anode button by snap-fit action, whereby upon engaging said spring engaging means with said anode button, said tubular end portion may be threadably tightened onto said contact assembly for causing the same to tightly engage the outside surface of said display device.
Claim 2
Dependent Claim
134 words
A connector for making high voltage connection to an anode button on a display device comprising: a receptacle designed for mating engagement with an appropriate lead assembly having a tubular end portion, a wide external flange on the tubular portion adjacent one end thereof closing the tubular opening at said one end, and a threaded axial opening in said flange of substantially smaller diameter than the diameter of the tubular opening; and a contact assembly threadably engageable with said threaded opening in said flange and having spring engaging means for engaging an anode button by snap-fit action, whereby upon engaging said spring engaging means with said anode button, said tubular end portion may be threadably tightened onto said contact assembly for causing the same to tightly engage the outside surface of said display device.
Claim 3
Dependent Claim
77 words
A connector according to claim 1, wherein said contact assembly comprises: an elongate male contact member having a screw head at one end and being threaded adjacent said one end; a metallic spring member having a base portion and radial spring fingers, said base portion having an opening for receiving said male contact member; and a nut for threadably engaging said male contact member and securing said spring member thereon between said screw head and said nut.
Claim 4
Dependent Claim
83 words
A connector according to claim 2, wherein said receptacle further has stepped cylindrical portions on the end of said flange opposite said tubular end portion, a central opening on the end one of said stepped cylindrical portions for receiving said nut of said contact assEmbly, and said end one of said stepped cylindrical portions is receivable in said anode button while the cylindrical portion of said stepped cylindrical portions adjacent said flange is adapted to contact the outer surface of said anode button.
Claim 5
Dependent Claim
38 words
A connector according to claim 3, further comprising sealing means adapted to be concentrically disposed about said anode button for being compressed between said flange and said display device upon threadably tightening said receptacle to said contact assembly.
Claim 6
Dependent Claim
63 words
A connector according to claim 1, wherein said receptacle further has an axially extending portion from the end of said flange opposite said tubular portion and an axial opening in said axially extending portion communicating with said threaded axial opening in said flange, and wherein said spring engaging means of said contact assembly are disposed in said opening in said axially extending portion.
Claim 7
Dependent Claim
131 words
A connector for making high voltage connection to an anode button on a display device comprising: a cylindrical member having an elongate axial bore in one end and a threaded axial opening in the other end of substantially less diameter than the bore and communicating with said bore; an elongate male contact pin externally threaded for engaging said threaded axial opening in said cylindrical member; spring engaging means secured to said male contact pin for engaging an anode button on said display device; an annular resilient sealing member; and means on said cylindrical member for engaging said resilient sealing member and upon threadably tightening said cylindrical member on said male contact pin for compressing said resilient sealing member against the outside surface of said display device about said anode button thereof.
Claim 8
Dependent Claim
131 words
A connector for making high voltage connection to an anode button on a display device comprising: a cylindrical member having an elongate axial bore in one end and a threaded axial opening in the other end of substantially less diameter than the bore and communicating with said bore; an elongate male contact pin externally threaded for engaging said threaded axial opening in said cylindrical member; spring engaging means secured to said male contact pin for engaging an anode button on said display device; an annular resilient sealing member; and means on said cylindrical member for engaging said resilient sealing member and upon threadably tightening said cylindrical member on said male contact pin for compressing said resilient sealing member against the outside surface of said display device about said anode button thereof.
Claim 9
Dependent Claim
22 words
A connector according to claim 6, wherein said cylindrical member is externally threaded at the end thereof having said axial bore therein.
Claim 10
Dependent Claim
53 words
A connector according to claim 6, further comprising means defining a cylindrical recess in said cylindrical member axially aligned with said axial bore and said threaded axial opening and disposed on the end of said threaded axial opening opposite said axial bore for receiving said spring engaging means of said male contact pin.
