Disclosed is an electronic component, especially a coil with a coil core, in which the turns of the coil winding are spaced apart from each other at least at one point in the longitudinal direction of the coil. A plastic retaining element which overlaps both the coil core and at least the two adjacent turns of the coil winding in a longitudinal direction is sprayed on in the area of said point, whereby a connection between the coil core and the coil winding is created at the same time. The retaining element can be sprayed around a closed circumference of the coil while covering only a portion of the coil in the longitudinal direction thereof. Preferably, the retaining element is placed approximately in the center relative to the longitudinal extension of the coil.
L'invention concerne un composant électronique, notamment une bobine comportant un noyau de bobine, dont les enroulements présentent un écart mutuel dans le sens longitudinal de la bobine, dans au moins une zone. Un élément de fixation en plastique est injecté dans cette zone, l'élément de fixation recouvrant le noyau de bobine ainsi qu'au moins les deux enroulements adjacents dans la direction longitudinale. Une connexion est ainsi créée entre le noyau de bobine et les enroulements. Il est ainsi possible d'injecter l'élément de fixation sur une périphérie fermée de la bobine, tandis que seulement une partie est recouverte dans la direction longitudinale de la bobine. L'élément de fixation est de préférence disposé au centre de l'extension longitudinale de la bobine.
