Plastic injection molding, Berlin SW 29 »Kottbusser Dam 79 High frequency iron core bobbin "

Ready high-frequency iron core bobbins were prepared, into which an earth core is screwed for adjustment purposes or to change the inductance, in such a way that the thread la Inside the high-frequency iron core coil & enträgsrs interrupted, aleo is only attached to bars or strips * This made it possible to use the high-frequency iron core coil carriers previously used in manufacture Eliminate the required conicity, as no mandrel can be unscrewed from these needed »

Furthermore, a proposal was made, Ia inside the Hoehfreguenzeisenkernspulentrers, in the axial direction, webs or strips of small width to be attached without thread. In these The earth core with thread was able to join bars or webs ■ • Press into the tip of the thread · The earth core thus received its seat in the high frequency iron core bobbin

In this construction, however, B · proved that the friction of the mass core in the high frequency iron core bobbin was still relatively large, which is particularly evident when aligning the Made coils annoyingly noticeable »

The present hiring provides that inside the high frequency iron core coil carrier made of low-loss, elastic plastics on the one hand the previously proposed one or several webs or strips without thread, which run in the axial direction and radially in the high-frequency iron core bobbin protrude, are attached and these webs or «strips opposite the thread Fig. I and Ia represent an embodiment of this hiring “The in the high frequency core coil carrier 1 to be screwed in ground core with thread 2 is obtained when twisting in the threaded part 3 of the high-frequency iron core bobbin 1 its year. Through the binding back of the thread tips 5 of the mass core 2 in the strips or webs 4 opposite the threaded part 3, the seat of the mass core » guaranteed and calibrated in the high frequency iron core bobbin over the entire area of the high-frequency iron core bobbin " screw in easily and softly "

Claims (2)

The advantage of the innovation over the previously used high-frequency iron core bobbins is that the Production does not require a threaded mandrel to be unscrewed, so that the parts receiving the mass core inside the High-frequency core bobbin (thread and webs or Strips) run absolutely cylindrical · With a preferred use of the present innovation, the previously due the conicity required inserts made of plastic, rubber, felt and similar compensating materials between Earth core and high-frequency iron core coil carrier were inserted, gone · This eliminates an additional work step and material costs can be saved » Am tighter seat of the mass core in the high-frequency iron core coil carrier can be achieved according to FIG. II with this innovation in that the pitch 6 of the thread in the threaded part 3 of the high frequency sinker coil support 1 not with the The pitch of the thread of the earth core to be screwed in matches, but is alternately larger or smaller, in such a way that that this difference is evened out again after a certain number of gears. This causes the earth core to jam And thus a tighter fit of the mass core in the high frequency iron core coil carrier a" A further embodiment of the innovation exists according to Fig. III in that the turns 6 of the threaded part 3 in the high-frequency iron core bobbin 1 are not helical as in the normal thread run, but lie on parallel circular paths. With this construction, too, there would be jamming of the earth core in the high-frequency sink core coil support, the one Firm seat of the earth core in the high frequency! guaranteed. Due to this tight fit of the mass core the process that has been common in industry up to now, namely to fix the mass cores after the adjustment (varnish or cast) would be superfluous. Protection claims 1) High-frequency iron core bobbin made of low-loss, elastic plastics into which an earth core with thread is screwed for adjustment purposes or to change the inductance is, characterized in that within the high-frequency magnetic core coil carrier on the one Side is a thread matching the pitch of the thread of the mass core and opposite one or several la axially extending, radially into the interior protruding strips or webs without thread attached are* ' 2.) high-frequency iron core coil support according to claim 1.) thereby ■ ■ ■ · marked that the pitch of the thread does not match the The pitch of the Maese core to be screwed in corresponds, but alternately becomes larger or smaller, in such a way that sioh these differences after a certain number of gears cancel again 3) high-frequency iron core coil carrier according to claim 1,) and 2.) characterized in that the threads of the thread part in High-frequency iron core bobbin not like the normal one Threads run helically, but lie on parallel circular paths «
