Coil bobbin and sealing coupler

A bobbin assembly for sealing with the end section of a coil of wire as it exits the housing of an automotive electrical component, comprising:

• bobbin means for receiving and carrying the coil of wire,
• a cap for coupling with the housing having the coiled wire therein, said cap including an aperture therein adapted to receive the end section of the wire therethrough, and
• tower means, coupled to and distending from said bobbin means, for defining therein a longitudinal slot for receiving, coupling and sealing with the end section of the wire, and for coupling with and sealing against said cap adjacent said aperture therein responsive to compression in the longitudinal direction exerted by said cap coupling to the housing.

A method for forming a seal between a housing of an automotive electrical component and a section of wire passing through an aperture in the housing, including the steps of:

• coupling a barrier only partially around the circumference of the section of wire,
• deforming said barrier radially about a longitudinal axis of the wire in response to compression along said longitudinal axis so as to form an effective seal around the entire circumference thereof, and
• compressing said barrier along said longitudinal axis of the wire and into the aperture of the housing so as to form an effective seal therebetween.
