Abstract
Abstract A deflection yoke includes a coil frame comprising a flared body and a pair of end formations at the front and rear ends of the body. Around each end formation, the frame is formed with a plurality of grooves, and a deflection coil is directly wound on the inner surface of the frame in a saddle configuration, utilizing the grooves.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A deflection yoke including a core and a pair of horizontal and vertical deflection coils, comprising a sleeve-shaped coil frame including a flare-shaped body and a pair of end formations integrally formed at its front and rear ends thereby forming a single unitary frame member, each of the front and rear end formations being formed with a plurality of grooves, at least one of the deflection coils being directly wound on the inner surface of the coil frame in a saddle configuration by fitting and anchoring a conductor into the grooves.
Claim 2
Dependent Claim
91 words
A deflection yoke including a core and a pair of horizontal and vertical deflection coils, comprising a sleeve-shaped coil frame including a flare-shaped body and a pair of end formations integrally formed at its front and rear ends thereby forming a single unitary frame member, each of the front and rear end formations being formed with a plurality of grooves, at least one of the deflection coils being directly wound on the inner surface of the coil frame in a saddle configuration by fitting and anchoring a conductor into the grooves.
Claim 3
Dependent Claim
28 words
A deflection yoke according to claim 1, further comprising means for constraining the position of the conductor on the inner surface of the body of the coil frame.
Claim 4
Dependent Claim
33 words
A deflection yoke according to claim 1 in which the spacing between adjacent turns of the conductor on the front end formation is different from the corresponding spacing on the rear end formation.
Claim 5
Dependent Claim
32 words
A deflection yoke according to claim 1 in which the open end of the grooves formed in the front and rear end formations is enlarged to facilitate entry of the conductor thereinto.
Claim 6
Dependent Claim
21 words
A deflection yoke according to claim 1 in which the coil frame is formed in a pair of semi-sleeve shaped halves.
Claim 7
Dependent Claim
18 words
A deflection yoke according to claim 1 in which the coil frame is a single piece sleeve-shaped body.
Claim 8
Dependent Claim
42 words
A deflection yoke according to claim 2 in which said means comprises a plurality of projections integrally formed on the inner surface of the body as a unitary structure, the conductor being engaged with the projections to form a bend in it.
Claim 9
Dependent Claim
55 words
A deflection yoke according to claim 2 in which said means comprises a plurality of axially extending steps integrally formed in the inner surface of the body of the coil frame as a unitary structure, thereby allowing the distribution of turns of the conductor to be varied across the inner surface of the coil frame.
Claim 10
Dependent Claim
50 words
A deflection yoke according to claim 2 in which said means comprises a tab integral with said body extending between the front and rear end formations on the inner surface of the body forming a unitary structure therewith for preventing a disengagement of the conductor from the inner surface thereof.
Claim 11
Dependent Claim
24 words
A deflection yoke according to claim 3 in which the spacing between adjacent turns of the conductor is increased toward the front end formation.
Claim 12
Dependent Claim
24 words
A deflection yoke according to claim 3 in which the spacing between adjacent turns of the conductor is reduced toward the front end formation.
