Between the outer profile legs 5, 6 of the Ef "rr.iigen Biechianeiien * is a likewise r-iis 3lechlanelien formed bar-like core 3 with a strict setting, with between the core 3 and the end face of the middle profile leg 2 of the ^ lecnlameIlen 1 ^ in insulating strips S for the formation of a luxt gap 7 e ^ir ".;. · - ■ .. ^ st, whose gap = ltgrL ^; -e by the thickness of the jewell ■ • er-ence'.an" scllerstrelfer.s S bestimb? .R is.

^; Substantially now that the outer edges of the profile legs 5, 6 of the laminations 1 wedge-shaped run renewal according to the Sc handle outward, so that the Pr 5.st in this embodiment, ; ,. ^ Henkel 5, 6 at their ends a larger profile width than in the area of them with each other ·? - and with the profile leg 2 connecting. Sheet metal lamellas 1 h = '- ■ · -. ■ In addition, the sheet metal lamellas 3 of the bar-like core are adapted to their profile width to the widened leg ends of the profile legs 5, 6 and are therefore wider than z.ß. the middle profile leg 2 of the sheet metal lamellas 1. This measure of widening the leg ends of the profile legs 5, 6 and the bar-like core 3 results in the desired effect of preventing or at least effectively reducing the scattering of the magnetic field lines in the areas of the joints 12, 13 of the core 3. One is the leg ends the profile legs 5, 6 of the sheet metal lamellas 1 with bent-up Spannbzw. Clamp-like rail 9, which is known per se and encompasses the outside, ensures the tight connection of the core end faces at the joints 12, 13 of the inner edges of the profile legs 5, 6 of the sheet metal lamellas 1. However, this rail 9 also ensures that the air gap 7 is maintained.

The illustrated in Fig. 2 second embodiment of the innovation according to ^ n throttle differs from the first Embodiment in that the bar-like core has a T-shaped profile and with its upright T-bar 14 the shortened Hittelschenkel 2 of the profile E-shaped sheet metal lamellas 1 of the jacket is opposite, so that dei ^ between the T-web 14 of the core 3 and the middle leg 2 of the sheet metal lamellas 1 remaining and formed by an insulating strip 8 The air gap comes to lie in the middle of the cross section of the throttle and the resulting scattering of the Maonetic field lines to the outside world at all.

In this embodiment, too, it is necessary to achieve this the effect sought after the innovation is essential that the leg ends of the profile legs 5, 6 of the E-shaped Sheet metal lamellas 1 are broadened in profile e.g. by a step 15 or 16 protruding in front of their outer edge and that the Profile cross-head of the T-shaped core 3 also in its width of the profile widening of the profile legs 5, 6 or the level 15, 16 is adapted. These steps 15, 16 offer the clamping strips 10, 11, which are counter-shaped in cross section to the steps the rail 9 is an abutment that increases the tension of the rail.

The throttle shown in Fig. 2 differs from the embodiment shown in Fig. 1 in that it has two independent coils 18, 19, of which the coil 1 8 on oem middle leg 2 of the sheet metal lamella. ¹ en 1 of the shell is pushed on and sits in the profile cavity 17 of the shell, whereas the coil 19 sits on the T-bar 14 of the sheet metal lamellas of the core 3 and is inserted together with these into the profile cavity 17 delimited by the profile legs 5, 6 of the shell 1 will. The core 3 sits with a tight fit between the profile legs 5, 6 of the shell. These coils 18, 19 are each connected to a power line, so that the disturbances occurring when starting the fluorescent tubes or in the fluorescent tube itself are kept away from the network.

3 shows an embodiment of the throttle in which the jacket 1 consists of iny'rofil U-shaped 31echlamellen 1 and has a core 20 formed from sheet metal lamellas formed in the shape of a cross in the shape of a cross. This core 20 butts with its upper The end face of the insulation insert 8 forming the air gap 7 and is supported with a lower end face on the Crossbar 3. With its horizontal profile part, the core 20 touches the inner surfaces of the profile legs 5, 6 of the sheet metal cladding lamellae 1, so that the profile cavity of the jacket in two cages

In this embodiment, too, it is essential that the IJ-förrr.igen profile legs 5, 6 of the sheet metal lamellas 1 are widened at their free ends by a step 15, 16 protruding from the outer edge in the frofile and also the beam 3 in terms of its profile width adapted to the widened leg ends d --r profile legs 5, 6 of the sheet metal lamellas 1 Owns tin diamonds.

Schni: U-shaped housing jacket 21 pushed on in a strictly fitting manner, which protrudes over the sheet metal lamella packet at the front but is open. This housing jacket 21 has the task of serving as an effective shield against the radiation of magnetic field lines into the air space surrounding the throttle. The legs of the U-shaped housing jacket 21 extend to the leg ends of the sheet metal lamellas 1 and there have outwardly bent felt edges 22. The second housing part consists of a base plate 23 made, for example, of sheet steel, the longitudinal edges of which face upwards and downwards inwardly bent mounting grooves 24 are designed. This base plate 23, which has a certain elastic tension, has to fulfill two tasks. Its first task is that it is pushed with its mounting grooves 24 onto the outwardly bent folded edges 22 of the leg ends of the housing shell 21 with appropriate bias and thereby not only the legs of the housing shell 21 »but also the knuckles 5, or sheet metal .ellen 1 in the direction of the bar-like core 3 under pressure se ~ ':. ^ t, so that the abutting edges of the core lamellas 3 pressed against the inner edges of the legs 5, 6 of the sheet metal lamellas 1 and tightly fitting butt joints 10 are formed in this way . The second task of the base plate 23 is that it presses the sheet metal lamellas of the beam-like core 3 against the unüfiagnetische plate 8 under its elastic tension and thus the. fixed by the strength of the latter certain Luftspa ¹ * ~. This pressure of the base plate 23 against the c.:.l '. n; .tigen core 3 can still be regulated by an intermediate layer 25. that was between the core 3 and the base plate ρ ■ ■ -t ..- ^j yt.

This two-part housing is quickly assembled and can also be used with U-shaped sheet metal lannels 1.
