Abstract
Abstract A housing assembly for a toroid yoke used in a television receiver is formed with an inner core sheath made of nonmagnetic material in the form of a truncated cone, with four locating fins located at equal distances about its periphery for facilitating locating of the beginning and termination of the windings of the yoke and for facilitating mounting of the core assembly within a main housing. The main housing is of substantially cylindrical configuration and has two guide channels for slidably engaging two of the support fins and two slots in which a slide clamp mounted on a corresponding fin on the yoke assembly is positioned for movement. The housing further includes a reduced diameter portion integrally formed therewith and resiliently attached to the yoke housing for expansion and contraction to engage a range of different cathode-ray tube neck diameters.

Claim 1
Independent Claim
176 words
A deflection yoke-housing assembly for use with the cathoderay tube of a television receiver including in combination: a core sheath for supporting the deflection windings and being of substantially hollow truncated conical configuration; a hollow housing member including a core sheath enclosing portion with said core sheath enclosing portion having a substantially cylindrical internal configuration of a diameter sufficient to accommodate the maximum diameter of the core sheath; at least two guide fins attached to the outside sloping surface of the core sheath, each guide fin having an edge extending substantially parallel to the axis of the core sheath guide fin channels formed in the core sheath enclosing portion of the housing member parallel to the axis thereof for accommodating and confining the guide fins attached to the core sheath to allow axial movement of the core sheath within the housing member; and cathode-ray tube neck engaging means on the housing member and adapted to receive a cathode-ray tube neck in engagement therewith to locate the housing member concentrically about the neck of a cathode-ray tube.
Claim 2
Dependent Claim
176 words
A deflection yoke-housing assembly for use with the cathoderay tube of a television receiver including in combination: a core sheath for supporting the deflection windings and being of substantially hollow truncated conical configuration; a hollow housing member including a core sheath enclosing portion with said core sheath enclosing portion having a substantially cylindrical internal configuration of a diameter sufficient to accommodate the maximum diameter of the core sheath; at least two guide fins attached to the outside sloping surface of the core sheath, each guide fin having an edge extending substantially parallel to the axis of the core sheath guide fin channels formed in the core sheath enclosing portion of the housing member parallel to the axis thereof for accommodating and confining the guide fins attached to the core sheath to allow axial movement of the core sheath within the housing member; and cathode-ray tube neck engaging means on the housing member and adapted to receive a cathode-ray tube neck in engagement therewith to locate the housing member concentrically about the neck of a cathode-ray tube.
Claim 3
Dependent Claim
31 words
The combination according to claim 1 wherein the core sheath includes a nonmagnetic sheath for fitting over and confining a deflection yoke core, the guide fins being attached to the sheath.
Claim 4
Dependent Claim
96 words
The combination according to claim 1 wherein at least one of the guide fin channels formed in the housing member is a slot in the housing member extending parallel to the axis of the housing member; the combination further including slide clamp means attached to at least one of the guide fins, the slide clamp means including engaging means for cooperating with the edges of said slot for slidable movement therein, and clamping means for clamping the slide clamp means to said housing to hold the core sheath at a predetermined location within the housing member.
Claim 5
Dependent Claim
55 words
The combination according to claim 3 wherein at least one other of the guide channels includes a pair of parallel-spaced rib means on the inside of the core sheath enclosing portion of the housing member and extending parallel to the axis thereof for slidably confining a corresponding guide fin between the pair of rib means.
Claim 6
Dependent Claim
71 words
The combination according to claim 4 wherein four guide fins are attached to the core sheath substantially 90* apart, with a first pair of diametrically opposite guide fIns having slide clamp means attached thereto and the housing member having corresponding slots for accommodating the slide clamp means, and the housing member further having diametrically opposite pairs of parallel-spaced rib means for slidably confining the other pair of diametrically opposite guide fins.
Claim 7
Dependent Claim
59 words
The combination according to claim 5 wherein the core sheath comprises a nonmagnetic sheath into which a core may be inserted, with the guide fins being attached to the sheath and serving to locate deflection windings to be wound on the core member and further serving to locate such deflection windings at a predetermined position within the housing member.
Claim 8
Dependent Claim
99 words
The combination according to claim 1 wherein the cathode-ray tube neck engaging means includes a plurality of axially extending arcuate neck engaging sections attached to the housing member with stiff flexible rib means to form a reduced diameter portion adapted to receive a cathode-ray tube neck in engagement therewith, the flexible rib means permitting displacement of the neck engaging sections to accommodate cathode-ray tube neck portions having different diameters, with the neck engaging sections moving in an arc to change the diameter of the reduced diameter portion, the sections remaining substantially parallel to the neck of the cathode-ray tube.
Claim 9
Dependent Claim
25 words
The combination according to claim 7 further including means interconnecting the neck engaging sections and expanding to change the diameter of said reduced diameter portion.
Claim 10
Dependent Claim
29 words
