An insulating cover forms two wiring cavities over a heat-sink base plate, between which cavities a conductor pattern plate mounted on the base plate extends. The cover also provides an integral connector shell. The larger part of the base plate is within a first wiring cavity in which circuit components are mounted on the base plate and bonded by wires to the conducting pattern plate. The second wiring cavity encloses contact springs affixed to the connector means and soldered to the pattern plate and this cavity is closed off with a cover plate that snaps into place. The protection so provided for the apparatus is adequate for the conditions in a motor vehicle engine compartment. |
