Electromagnetic deflection unit for color cathode-ray tubes, comprising a pair of horizontal deflection coils and a pair of vertical deflection coils, the saddle-shaped vertical deflection coils having a rear bundle on the electron-gun side and a front bundle located on the screen side, lateral conductor harnesses 120 connecting the two bundles so as to produce a main window in the intermediate region lying between these said bundles, the conductor harnesses being arranged so that, at the end of...

A deflection yoke is used for a cathode ray tube (CRT) including a glass tube having a screen surface and a straight portion for accommodating an electron gun. The deflection yoke includes a main deflection yoke including first and second horizontal deflecting coils and first and second vertical deflecting coils, and a sub-deflection yoke provided at a side of the main deflection yoke towards the electron gun of the CRT. The first and second horizontal deflecting coils have substantially saddle ...

Disclosed is a deflection yoke comprising: a fastening band of a ring shape assembled on an outer periphery of a neck portion in a coil separator by a fixing manner, provided for being extended and contracted; a pair of flanges bent and extended from both ends of the fastening band, on which a through hole is formed; a yoke clamp for generating fastening force by tightening of a bolt for passing through a pair of through holes, then being tightened by a nut; a bending portion projected on an out...

A deflection yoke apparatus include a saddle-type coil bobbin, first guide grooves, second guide groove, third guide groove, and a multi-wire conductor. The saddle-type coil bobbin has a front end portion and a rear end portion. The first guide grooves is formed in the inner surface of the coil bobbin and extends across the front end portion and the rear end portion. The second guide groove is formed in the front end portion of the coil bobbin. The third guide groove is formed in the rear end po...

The present invention relates to a deflection yoke comprising a coil separator having a plurality of connection projections which are formed in the front/rear and left/right sides of a lower flange surface of a peripheral surface and which include protrusions on both sides and a central portion between the protrusions being as high as the flange surface; a ferrite core installed to form a magnetic field on the peripheral surface of the coil separator; a vertical deflection coil positioned with t...

Disclosed herein is a horizontal deflection coil for a deflection yoke. The horizontal deflection coil includes an inner pincushion improving section connected to a screen bent, and sub-sections connected to the inner pincushion improving section. The inner pincushion improving section is disposed in an angular range of 45 to 60 degrees. The sub-sections include a horizontal color registration improving section for preventing a horizontal component of a green color from being widened, and a vert...

A deflection yoke mounted on a rear portion of a cathode ray tube (CRT) to deflect an electron beam emitted from an electron gun of the CRT includes a coil separator mounted on the CRT, a horizontal deflection coil mounted on an inside of the coil separator, having a first section generating a horizontal deflection magnetic field deflecting the electron in a horizontal direction and having a first radius, having a second section generating a magnetic field to weaken the horizontal deflection mag...

A deflection clip comprising a planar base plate comprising a first surface and an opposing second surface, and a guide depending from the base plate. The guide comprises a first arm extending along a longitudinal axis substantially transverse to the base plate from a proximal end adjacent the second surface. The guide further comprises a second arm extending away from the base plate oriented in the same direction as the first arm defining a channel between the arms.

Each horizontal deflection coil 2 comprises the smaller diameter flange 2A. A width "b" of the smaller diameter flange 2A in the horizontal direction of a screen of a color picture tube is more than twice a height "a" of the smaller diameter flange 2A in the vertical direction of the screen.

The present invention relates to a deflection yoke. According to the invention, in particular, anti-release means is provided in upper hook pieces formed in sides of a rear cover thereby preventing a printed circuit board from easy separation from the rear cover in fixing therebetween so that the assembling ability and productivity can be enhanced.
