Patent ID: 8451081

Claim:
A coil assembly to be mounted on a circuit board comprising: a bobbin made from an electrically insulating material and including a wound portion having an end portion, a terminal base positioned at the end portion, and a wire engaging portion protruding from a bottom surface of the terminal base; at least one electrically conductive wire formed with an electrically insulation coating and including a winding portion wound over the wound portion and draw-out portions each drawn out from the winding portion and engaged with the wire engaging portion; a first pin support portion and a second pin support portion protruding in a protruding direction from the bottom surface of the terminal base; and a first pin terminal protruding in the protruding direction from a free end face of a first pin support portion and supported thereto, and a second pin terminal protruding in the protruding direction from a free end face of the second pin support portion and supported thereto, each of the draw-out portions being electrically connected to associated one of the pin terminals, the pin terminals being configured to extend through the circuit board in the protruding direction which is substantially perpendicular to a surface of the circuit board; wherein the second pin support portion provides a protruding length from the terminal base greater than that of the first pin support portion, and the free end face of the second pin support portion being positioned downstream, in the protruding direction, of an imaginary linear draw-out portion directed linearly from the wire engaging portion to the first pin terminal, such that the second pin support portion is positioned and sized to intersect with the imaginary linear draw-out portion.
