Claims
- 1. A deflection unit for a cathode ray tube comprising:
- a. first and second saddle-type deflection coils preformed into predetermined shapes and disposed at predetermined positions relative to each other;
- b. hollow synthetic-material coil-support means having permanent deformations, into which respective portions of said coils extend, for holding said coils in said predetermined shapes at said predetermined positions, said permanent deformations comprising impressions of said portions of said coils, and
- c. said coil support means includes at least two lugs into which respective ones of said permanent deformations are impressed such that said coils are substantially free from said coil support means.
- 2. A deflection unit as in claim 1 where the coil-support means comprises a first part having lugs and a second part secured to the first part, said lugs including portions extending away from a body portion of the first part and having respective ones of said deformations formed therein.
- 3. A deflection unit as in claim 2 where the lugs consist essentially of a thermoplastic material.
- 4. A deflection unit as in claim 1 where the coil-support means comprises first and second annular parts surrounding a common axis and having adjacent ends secured to each other, said first part including a plurality of lugs extending at an angle with respect to a body portion of said first part and having respective ones of said deformations formed therein.
- 5. A deflection unit as in claim 4 where the coil-support means includes a third annular part surrounding said axis and where the first and third annular parts have adjacent ends secured to each other.
- 6. The deflection unit as claimed in claim 1 wherein the saddle-type deflection coils are substantially free from the conical part of said coil support means.
