Control device for an electric heating device and method for its production

摘要

The invention relates to a controller for an electric heating device, comprising a support element (48) and a busbar (20) which is secured on the support element and which is connected to an SMD component (4) in an electrically conductive manner. The aim of the invention is to provide a controller with improved electric conductive tracks for the power flow, said controller being producible in an economical manner, and thus also to provide a method for producing such a controller. The busbar of the controller according to the invention is part of an initially single-part stamped metal plate (8) with a severed connecting piece (14) which separates the metal plate (8) into a supply element (20) and a discharge element (26), said elements being connected together in an electrically conductive manner solely via the SMD component (4). In the method according to the invention, the following steps are carried out: - producing a stamped metal plate (8) which forms at least one supply element region (20B) and a discharge element region (26B) that are connected together via at least one connecting piece (14); - mounting an SMD component (4) on the supply element region (20B) in order to form an equipped metal plate unit (2); - securing the equipped metal plate unit (2) to a support element (48); and - severing the at least one connecting piece (14) such that a supply element (20) and a discharge element (26) are produced from the supply element region (20B) and the discharge element region (26B), respectively, said elements being connected together in an electrically conductive manner solely via the SMD component (4).
