Abstract
A sensor for detecting the angular velocity of a rotating member. The sensor includes a bobbin having an exterior defining an annular recess and a coil within the recess. The bobbin also has a generally cylindrical aperture and supports a probe and a permanent magnet in the aperture. The housing is secured to the bobbin and the housing and bobbin include tapered inner and outer surfaces, respectively, that are made to form a wedge fit seal between the bobbin and the housing to prevent the introduction of molding material during the overmolding process. The bobbin also includes supports for supporting the lead wires extending between the coil and the terminals.
Claims4
A sensor for detecting the angular velocity of a rotating member, said sensor comprising:
- a bobbin having an outer surface, said outer surface defining an annular recess;
- at least one electrically conductive terminal mounted on said bobbin;
- a coil mounted on said bobbin and within said recess;
- a lead connected to said electrically conductive terminal and to said coil and having a portion of said lead extending between said recess and said terminal;
- and
- a support on said bobbin for supporting and positioning adjacent to said bobbin said portion of said lead extending between said recess and said terminal, said support including a shelf having thereon a tang spaced from said outer surface and a sloped chute between said outer surface and said tang to receive said portion of said lead so that said shelf and said tang support and position said portion of said lead within said chute and against said outer surface and prevent radially outward movement of said portion away from said surface.
