Abstract
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.
Claims20
A coil assembly comprising:
- a bobbin having an open end;
- coil wound upon said bobbin, said coil including a pair of lead wires;
- a pair of compliant electrical connectors carried by said bobbin, each of said electrical connectors being electrically connected to one of said coil lead wires, said electrical connectors being adapted to electrically couple said coil lead wires to an electronic control unit;
- a flux return casing at least partially enclosing said coil;
- and
- at least one elongate resilient member molded upon an end of said bobbin, said resilient member configured to urge said bobbin and said flux return casing in an axial direction.
