摘要:
A liquid crystal display having a liquid crystal cell (1) has electrical heating formed by an electrically conductive heating layer (3) on a substrate (2). On opposite sides, a clamp (4) forming a busbar in each case reaches over the substrate (2) and bears on the heating layer (3) by a limb (5). For connection to the heating current source, a spring element (7) is arranged between a limb (6) of the clamp (4) and a printed circuit board (8).

An instrument cluster has a rigid printed circuit board (3) on the rear side of a basic (1). On the front side, the basic body (1) is partially covered by a supporting body (10) which is connected in an articulated manner to the basic body (1). A flexible printed circuit board (12) extends over the front side of the basic body (1) and the supporting body (10), the printed circuit board having a connecting region (13) which is deflected by a defined angle with respect to an edge region of the rigid printed circuit board (3) and is connected to this printed circuit board (3) by bow-type soldering (14) for example.
摘要:
A combination instrument for a motor vehicle, having a front frame and a display panel and a plurality of display instruments and warning lights which are arranged on a printed circuit board and are provided for displaying information on the display panel. The front frame is produced integrally with light shafts which lead from the warning lights to the display panel. In the region of the warning lights, the display panel is formed by a diaphragm screen which is adhesively bonded to the front frame and is produced as a film. The light shafts simultaneously serve as spacers for the printed circuit board.
摘要:
A multipole electric motor having a plurality of pole laminations (8-11) guided from ends of coils (4, 5) to a permanent magnet (13) of a rotor (14), the pole laminations (8-11) are firstly produced as a coherent sheet-metal part, and is partially injection-coated with a plastic. Subsequently, the pole laminations (8-11) are separated from one another by means of a laser beam, for example. This renders the mounting of the pole laminations (8-11) particularly simple.
摘要:
A combination instrument has a base body (9) which is split into display areas oriented at different angles relative to one another. An additional printed circuit (1) extending over a plurality of display areas is arranged on the front of the base body (9). This additional printed circuit comprises rigid printed circuit parts (2, 3, 4) which have flexible connecting regions (5, 6) with conductor tracks in the junction region of the display areas.
摘要:
An instrument cluster having a housing, a system support (21) to receive indicating instruments, and a circuit board (6) which is connected by fastening elements (35) to the system support (21) and mounted in floating fashion.
摘要:
A combination instrument for automotive vehicles, in which different indicating instruments, indicating fields, control and warning lights, and, possibly, operating parts as well as electrical and electronic equipment parts, are arranged in common housing. The combination instrument comprises a computer unit with microcomputers (36) and/or use-specific integrated circuits which are arranged, for protection against electromagnetic disturbances, within a housing (31) which is impervious to high frequencies. Furthermore, disturbance-endangered incomiing and outgoing lines (41, 43, 46) are protected, upon entrance or exit, by suitable filter measures. These include leadthroughs with leadthrough capacitors (45) and the use of ferrite cores (47, 48) through which connecting lines are extended. For shielding against disturbing radiation and for obtaining a low profile of installation, in one embodiment, a lower part (38) of a multiple-plug-type connector is fastened on a least one outer surface of the high-frequency-proof housing, and electrical contacts are formed by elongated conductors (32) which extend in a single piece from a circuit board (33) through a housing wall (34) into the plug-type connector.
摘要:
A warning device with central indication of operating conditions to be monitored in motor vehicles, with an indicator device which is controllable by a monitoring device. The space for representation of the operating conditions to be monitored that is used is that which is already provided in the dashboard console for indication of the information concerning the clock time.
摘要:
A light source is described, which is composed of a large number of light-emitting diodes (7) in an array arrangement. The light source comprises a mounting board (2) on which a flexible printed circuit (4) is adhesively bonded, on whose free surface a large number of light-emitting diodes (7) are mounted. Their lines (8) make contact with contact pads (10) at the ends of conductor tracks (9) on the flexible printed circuit (4).
