Disclosed are a coil assembly of a solenoid valve for an electronically controlled brake system and an assembly structure of an electronic control unit. According to an embodiment of the present invention, provided are the coil assembly of a solenoid valve for an electronically controlled brake system, which is connected to the electronic control unit with a printed circuit board and applies power to the solenoid valve installed in a hydraulic block, and the assembly structure of an electronic control unit. The center of the coil assembly is penetrated so that the upper part of the solenoid valve can be inserted into the coil assembly. The coil assembly comprises: a cylindrical bobbin, which has coils wound on the outer periphery; a coil case, which wraps the coils wound on the bobbin; and a housing, which has an insertion groove for the coil assembly to be inserted in. The printed circuit board is arranged in the electronic control unit combined with the hydraulic block to be apart from the coil assembly at a predetermined interval from each other. A coil spring penetrates the housing. One end of the coil spring is in contact with the printed circuit board and the other end has an elastic member in contact with the coil case. The elastic member of the coil spring has an elastic force toward the longitudinal direction. The elastic force is different in both directions. |
