Abstract:
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 is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting "slide lock" and "snap lock" self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

Abstract:
The invention relates to an exterior door handle, particularly for vehicles, and to a method for the production thereof. The exterior door handle comprises a moveable handle in form of an at least regionally hollow housing, in which electronic components (31) can be accommodated. Furthermore, a printed circuit board (30) is provided, which is used to accommodate at least some of the electronic components (31). Furthermore, a Hall element (20), which is to be arranged in a predefined location in the handle, is provided in the handle. According to the invention, the printed circuit board (30) is designed in a rigid and flat manner and a separate holder (10) is provided. Said holder (10) carries the Hall element (20) and holds it in the predefined position thereof in the interior of the handle. The position is spaced from the printed circuit board (30).
Abstract:
Apparatus and methods for supporting a fluorescent lamp. The apparatus may include a ballast and one or more lamp holders. The lamp holders may be in electrical communication with the ballast via a conductor. One or more lamp holders may be removably attachable to the ballast. When a lamp holder is attached to the ballast, it may be attached in a manner that places the lamp holder in electrical communication with the conductor. The apparatus may include a lamp holder module that may support one or more lamp holders. When a lamp holder is attached to the lamp holder module, it may be attached in a manner that places the lamp holder in electrical communication with a conductor that is configured to distribute power to lamp holders that are attached to the lamp holder module.
Abstract:
A waterproof method for an electronic device (3) and a waterproof electronic device (3) are provided. The electronic device comprises a printed circuit board (20), which comprises a board (21), a plurality of electrical elements (23) and a button device (29). The waterproof method comprises the following steps: applying a first non-solid adhesive to cover the button device directly, curing the first non-solid adhesive to form a first waterproof layer (27a), applying a second non-solid adhesive to at least cover the electrical elements directly and curing the second non-solid adhesive to form a second waterproof layer (27b). In the end, assembling the printed circuit board, sealed with the waterproof layers, into a case to form the waterproof electronic device.
Abstract:
An over-molded electronic module (2) includes a frame (10), an electronic assembly (20), and a polymeric body (32). The frame (10) includes a sidewall (14) that defines an opening (12) to provide a position for the electronic assembly (20), and includes an upper face (16) and a lower face (18) opposite the upper face (16) to act as sealing surfaces during over-molding. The polymeric body (32) is formed of a polymeric composition encapsulating both sides of the electronic assembly (20) and a portion of the frame (10).
