Herstellungsverfahren einer Ablenkspule

摘要

There is provided a deflection coil and a fabrication method thereof wherein conductors of the deflection coil are prevented from being, displaced and biassed and no gap is produced among laminates of the conductors, and the deflection coil is constructed in a short time. Grooves are formed in a surface of a bobbin, in each of which grooves a band-shaped parallel electric conductor (7) is arranged and laminated, said parallel electric conductor being composed of a plurality of parallel electric conductor wires bonded with each other through a bonding layer. A thermoplastic resin layer (8) which has a lower softening temperature than an insulating layer and the bobbin is formed on the outermost layer of the parallel conductor insulated through and coated with the insulating layer. The parallel conductors (9) are arranged and laminated in a coil winding groove formed on the bobbin to take a configuration of a saddle type deflection coil, and thereafterthe parallel conductor is supplied with power to thereby heat and soften the thermoplastic resin. In contrast, a pressurizing tool is inserted into the coil winding groove in the bobbin to pressurize the wound and laminated parallel conductors from the upper portion of the same and hereby bring the laminates of the parallel conductors into close contact for integration thereof.
