LIGHTWEIGHT AUDIO SYSTEM FOR AUTOMOTIVE APPLICATIONS AND METHOD |
摘要 |
A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) 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 EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture integrally forms a resilient beam portion adjacent an edge thereof carrying a grounding pad. The major components and subassemblies are self-fixturing during the final assembly process and self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. |

1. A lightweight automotive electronic device comprising:
at least one electronic circuit component including a circuit board integrally forming a resilient beam portion adjacent an edge thereof carrying a grounding pad; and a housing assembly substantially formed of a composite of relatively rigid polymer based material and electrically conductive material operable to substantially enclose and to shield said at least one electronic circuit component from electrical anomalies, wherein an inwardly facing exposed portion of said conductive material is disposed adjacent said grounding pad to establish an electrical ground path therebetween. |
