Abstract
Abstract A deflection yoke for use with a cathode ray tube includes a pair of half-cut separators joined together to form a complete separator, a pair of saddle wound horizontal deflection coils mounted on the separator halves and a pair of toroidal wound vertical deflection coils wound about half-cut coils and assembled about the separator. The plane of separation between the saddle wound horizontal deflection coils, the half-cut separators and the toroidal wound vertical deflection coil is the same plane. Provision is also made for proper orientation of the saddle wound horizontal deflection coils in each half-cut separator and for location of the toroidal wound vertical deflection coil about the separator.

Claim 2
Dependent Claim
87 words
A deflection yoke for use on a cathode ray tube comprising a pair of separator halves having a planar mating surface of engagement, each of said separator halves having interengaging means to join said halves together, a deflection coil mounted in each said separator half, means to support said deflection coil in each said separator half, said deflection coils being positioned within said deflection yoke such that the plane of separation between said coils is coincident with the planar mating surface of engagement of said separator halves.
Claim 3
Dependent Claim
78 words
A deflection yoke according to claim 1 wherein said deflection coils mounted in each said separator half are saddle wound horizontal deflection coils and including a pair of toroidal wound deflection coils each wound about a core half, said vertical deflection coils being positioned about said separator and having the plane of separation between said vertical deflection coils coincident with the plane of separation of said horizontal deflection coils and the planar mating surface of said separator halves.
Claim 4
Dependent Claim
91 words
A deflection yoke for use on a cathode ray tube comprising a pair of identical separator halves joined together in a planar mating surface of engagement, each said separator half comprising a front portion, a rear portion and a gradually widening segment interconnecting said front and rear portions, said front and rear portions including outwardly facing flat bearing surfaces to receive and support the bending portion of a saddle wound deflection coil supported within said separator half and means on each said separator half to locate and support said deflection coil.
Claim 5
Dependent Claim
91 words
A deflection yoke for use on a cathode ray tube comprising a pair of identical separator halves joined together in a planar mating surface of engagement, each said separator half comprising a front portion, a rear portion and a gradually widening segment interconnecting said front and rear portions, said front and rear portions including outwardly facing flat bearing surfaces to receive and support the bending portion of a saddle wound deflection coil supported within said separator half and means on each said separator half to locate and support said deflection coil.
Claim 6
Dependent Claim
70 words
A deflection yoke according to claim 3 wherein said means to locate and support said deflection coil includes a flange portion about the periphery of said front portion bearing surface, resilient members disposed in said flange portion to resiliently abut against a bent portion of said deflection coil and resilient retaining members formed adjacent the mating surface of said interconnecting segment to restrain a mid segment of said deflection coil.
Claim 7
Dependent Claim
87 words
A deflection yoke according to claim 3 wherein each said separator half includes coupling means adjacent its mating surface for interlocking engagement with a mating separator half comprising an extending locating pin and locking projection having an enlarged end adapted to mate with a complimentary receiving bore and projection receiving opening when said pair of separator halves are joined together, said locking projection extending through said projection receiving opening with said enlarged head bearing against the surface defining the opening to securely lock said separator halves together.
Claim 8
Dependent Claim
47 words
