Abstract
An electrical connector for connecting a solenoid wire coil to a printed circuit board in an automotive anti-lock braking system has a coil bobbin, around which the wire coil is wound. The wire coil has pre-tinned sections that are wrapped over stems protruding from the coil bobbin. When the stems are inserted in through-holes of the printed circuit board, the pre-tinned sections contact the through-holes, establishing a connection between the solenoid coil wire and the printed circuit board without soldering. In a preferred embodiment, the connector includes a bobbin outer mold and a stem outer mold covering the bobbin and stems, respectively, for protection against environmental conditions. A seal at the juncture between the stem and bobbin outermolds provides further protection of the coil.
