Lightweight audio system for automotive applications and method

摘要

A lightweight radio/Audio player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips.

1. A guillotine heat sink for an automotive electrical system comprising:
a heat sink structure defining opposed generally parallel guide surfaces; a system housing assembly including wall portions defining opposed cooperating guide slots within a cavity formed thereby, said guide slots configured for slidably receiving said heat sink, wherein said housing assembly is formed of a composite of relatively rigid polymer material and a wire screen insert molded within the polymer material and extending substantially continuously along housing assembly wall portions; and an electrical assembly including a heat generating component disposed within said cavity in register with said guide slots wherein a leading contact surface of said heat sink abuts an exposed surface of said component to establish a thermally conductive path therebetween.
