Abstract
A flyback transformer includes an anode lead wire composed of a core wire and an insulating film for covering the core wire and supplying a high output voltage to a CRT. A cylindrical anode lead holding device includes engagement pieces have spring-like properties which allows the pieces to restore to their original positions after having been extended in a radial direction. These engagement pieces project from the inner surface of the anode lead holding device and hold the anode lead wire. The anode lead wire has a groove formed on a part of or around the whole circumference of the insulating film. The groove engages the engagement pieces, such that the anode lead wire is held by the anode lead holding device.

A flyback transformer, comprising:
- a transformer section including a magnetic core and an associated coil;
- an anode lead wire comprising a core wire and an insulating film for covering said core wire, wherein said anode lead wire supplies a high output voltage generated in said transformer section to a cathode ray tube;
- and
- an anode lead holding means having at least one engagement piece having elasticity in at least a radial direction of said anode lead holding means, wherein said at least one engagement piece projects from an inner surface of said anode lead holding means;
- wherein said anode lead wire has a groove formed on a section of said insulating film;
- and
- wherein said groove engages with said at least one engagement piece, whereby said anode lead wire is held by said anode lead holding means.
