A combination instrument (1) has a front frame (2) having a cover (7) which has a plurality of recesses (4, 5) for indicating instruments or other displays. The cover (7) is covered with a decorative element which is formed as a molding (3) and around which a section (8), which is designed as an undercut, of the front frame (2) grips. To this end, the front frame (2) is produced in an injection molding process, the molding (3) being placed into the injection mold. The connection of the molding (3) to the front frame (2) can take place such that it is invisible to someone looking at it, thereby enabling an attractive, visual appearance and simultaneously reliable way of fixing it to be achieved.

An invention relates to an indicating instrument, in particular for a motor vehicle, having a housing with a front frame holding a cover pane, and an elastic spacing element arranged between the cover pane and front frame, and a method for connecting the cover pane to the front frame. In order to ensure a reliable connection between the cover pane and front frame which is without play, the spacing element be is placed in an axial cutout which is arranged in the region of the circumference of the front frame and faces the cover pane, and in which the cover pane can engage. The method consists in that in a first step the spacing element is inserted into the axial cutout in the front frame, and in a second step the cover pane is pressed into the axial cutout against the spacing element.

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).

A plug socket (1) has a plug housing (2) with a baseplate (3). The baseplate (3) has a respective contact surface (9,10) on two opposite sides in order to seat it on a printed circuit board. A contact spring (6) has two support regions (7,8) which are curved in the shape of an arc in opposite directions and which together form the shape of an S lying on its side. The contact spring (6) permits conductor track contact both in the case of surface mounting and plug-in mounting for the plug socket (1).

A device for controlling an opto-electronic display device has dot-matrix display elements (15), a controller (10) which has an addressable dot-matrix character table (addresses 20-35; 36-41 as well as 45 (in part), 46 and 47), a program control device as character generator and at least one driver (19). Information can be displayed in dot-matrix form. In order to display, in parallel, other information in a segment display, the addressable dot-matrix character table has an additional, similarly addressable and structured table part (addresses 20-35 as well as 42-44 and 45 (in part)), in which, instead of dot-matrix data, segment data containing the segment character set are stored in a code which is constructed according to segment connections (electrode connections S1-S3; Z1-Z5). The character table (17) which has been expanded in this manner can be controlled by the expanded program control device and is connected via the driver (19), adapted to the segment display elements, with the dot-matrix display elements (15) and with the segment display elements (11-14).
摘要:
A printed circuit board, in particular for a display instrument in a motor vehicle, having a coupling element of a plug-in device and having one or more clearances and one or more terminal contacts of the coupling element which pass through the clearances, the coupling element having a base connected to the printed circuit board and the terminal contact or contacts on the side of the printed circuit board which is facing away from a coupling region of the coupling element being electrically connected to said printed circuit board.To simplify the production of the printed circuit board, the base of the coupling element has a connecting element which passes through the printed circuit board in a clearance, can be twisted about an axis running approximately perpendicularly with respect to the printed circuit board and locks the coupling element to the printed circuit board, and the clearance through which the connecting element passes is arranged in a plane approximately parallel to the printed circuit board at an angle with respect to the connecting element and that the connecting element is twisted when it is inserted into the clearance.

A plug-in connector for an electric system, in particular for motor-vehicle instrument clusters, in which an electrical contact arranged in a first connector part can be detachably connected by an actuating device with a mating contact which is fastened in a second connector part. In order to fasten the indicating device in an easy and inexpensive manner to the instrument board and, at the same time, permit a reliable electric contact to be made, the electric contact is connected to the electric mating contact by a linear movement of the actuating device within the first connector part which has the electric contact and is fastened on a circuit board. The second connector part is firmly attached to a support element. During the contacting of contact and mating contact, the first connector part can be simultaneously locked with the support element by a locking device for the actuating device which protrudes beyond the first connector part in the direction of movement.
