Abstract: A brush holder assembly for an electric motor and a method of making it. The assembly comprises a unitary structure formed of a molded plastic housing in which a stamped and formed metal circuit plate is encapsulated. Separate circuit strips are formed by punching circuit bridges out of the plate after it is encapsulated. The separate circuit strips are embedded in one face of a web spanning the housing. On the opposite face of the web, brush holder channels are molded. The separate circuit strips each have a terminal formed unitarily with them, the terminals being embedded in a socket extending radially, outward from the web through a skirt encircling the web.

Abstract: A sensor assembly for sensing the air-to-fuel mixture in an internal combustion engine, and a method of manufacturing it. The assembly comprises a premolded plastic panel which is adapted to receive a Kapton and a terminal strip stamping. The stamping is positioned over the Kapton on registry pins in the panel. Another panel is then injection molded over the stamping and Kapton, welding itself to the one panel. The stamping and Kapton are encapsulated without damage to the Kapton. Terminal strip bridges are then removed from the stamping and a resistor welded between two of the strips.
