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

Control unit for vehicle brake system

A coil assembly comprises a coil wound upon a bobbin. A pair of terminals is supported by the bobbin. The coil has a pair of lead wires, each of which is connected to one of the terminals. Each terminal is adapted to be coupled to an electronic control unit. The coil is enclosed at least in part by a flux return casing. At least one resilient member is arranged and configured to urge the bobbin and the casing axially downward.

Self-locating coil assembly

An internal electrical connector includes at least one electrical conductor overmolded by a body formed from an electrically non-conducting material. The connector is received by a bore extending through a valve body for an anti-lock brake system hydraulic control unit. An electronic control unit mounted upon a first surface of the valve body is electrically connected to one end of the connector while the other end of the connector is electrically connected to a pump motor mounted upon a valve body surface opposite from the electronic control unit. The connector is free to move both transversely and axially within the valve body bore to compensate for component tolerance stack up.
