Abstract
Bei einem Zeilentransformator für einen Fernsehemp fänger, bei dem Anfang und Ende der Primärwicklung (4) am selben Ende des Spulenkörpers (15) enden, wird zur Erzielung der notwendigen Spannungsfestigkeit eine Iso lierfolie zwischen den beiden Teilwicklungen (4a, 4b) be nötigt. Außerdem muß erreicht werden, daß die Verguß masse (17) einwandfrei in die Zwischenräume der Win dungen der Primärwicklung (4) eindringt. Zur Einsparung der Isolierfolie und zur Verbesserung des Eindringens der Vergußmasse (17) ist der Spulenkörper (15) an seiner Oberfläche mit axial verlaufenden Nuten (16) versehen, durch die die Vergußmasse (17) hindurchfließen kann. In a line transformer for a television temp catcher, at the beginning and end of the primary winding (4) end at the same end of the bobbin (15) becomes Achieving the necessary dielectric strength iso lier between the two partial windings (4a, 4b) be compelled. It must also be achieved that the potting mass (17) perfectly in the spaces between the win the primary winding (4) penetrates. For saving the insulating film and to improve the penetration of the Potting compound (17) is the bobbin (15) on it Provide the surface with axially extending grooves (16), through which the sealing compound (17) can flow.
