Abstract

An electronic control unit comprises: an injection-molded supporting structure (4) for forming a cavity therein; a circuit board (11) mounted on the supporting structure; at least two electrically conductive members (20,21) combined with the supporting structure (4) during molding the supporting structure (4), wherein one end of the electrically conductive member is connected with the circuit board (11) and another end extends into the cavity (17); at least two flexible conductors (22,23), each flexible conductor comprising a corresponding insulation outer layer, wherein the flexible conductors (22,23) are combined with the supporting structure (4) when molding the supporting structure (4) and the ends of the flexible conductor (22,23) extend into the cavity (17) and permanently electrically connected with the conductive members (20,21) and the connection position of the flexible conductors (22,23) and the conductive members (20,21) is covered and sealed by a water-proof insulation material. The water intake risk of the electronic control unit is reduced and the member short circuit is prevented.

Description

technical field [0001] The invention relates to an electric control unit, which can be used as a speed regulator of an electric fan. Background technique [0002] US Patent No. 7,085,138 discloses an electronic control unit, which includes a circuit board installed with electronic components, a support structure for mounting the circuit board, and multi-strand wires for connecting the electronic control unit and controlled equipment. The support structure is made of plastic, and at least two conductive terminals are partially bonded to the shell of the support structure during the injection molding process of the support structure, the two conductive terminals are connected to the circuit board and serve as output terminals of the electronic control unit. The multi-strand wire includes at least one pair of flexible conductors, each flexible conductor has a corresponding insulating outer layer, one end of the flexible conductor is connected to the above-mentioned output termi...
