Coil assembly

An electronic control unit comprising:

• a housing adapted to be mounted upon a hydraulic valve body;
• a circuit substrate mounted within said housing;
• a coil spacer mounted upon said substrate;
• said coil spacer including at least one coil support ring having a resilient member extending in a radial direction from the edge of said ring into the center of said ring;
• and
• a solenoid coil and flux casing assembly mounted upon said coil spacer ring;
• said coil flexing said resilient member such that said resilient member urges said flux casing away from said coil spacer.

A method for assembling an electronic control unit comprising the steps of:

• (a) providing at least one solenoid coil;
• (b) mounting the solenoid coil upon a coil spacer;
• (c) mounting the coil spacer upon a circuit substrate to form an assembly;
• (d) inserting the circuit substrate and coil spacer assembly into a housing.

A hydraulic control unit for a vehicle comprising:

• a hydraulic valve body adapted to be connected to a vehicle hydraulic brake system;
• at least one solenoid valve mounted upon said hydraulic valve body;
• a pressure sensor mounted upon said hydraulic valve body;
• a housing removably attached to said valve body;
• a circuit substrate disposed with said housing;
• a coil spacer carried by said circuit substrate;
• and
• an pressure sensor electrical connector carried by said coil spacer, said electrical connector connecting said pressure sensor to said circuit substrate and being enclosed within the hydraulic control unit.
