Problems solved by technology

However, this requires special tolerances between the individual components of the front part and the individual components of the base part and thus leads to high manufacturing costs for the tachograph
[0005] Furthermore, it is conceivable to seal the wire connections to the electronic components against moisture, which likewise leads to higher manufacturing costs of the tachograph and is also prone to failure

Embodiment Construction

[0021] figure 1 A sectional view of a tachograph for a motor vehicle is shown with a base part 1 and a front part 2 . The tachograph is shown at the intended installation location. The base component 1 has a first electronic assembly 3 with a system circuit board 4 . The first electronic assembly 3 is used, for example, to detect driver- and motor-vehicle-related data, to control a printing device (not shown) and a storage device for a chip card, also not shown. The front part 2 has a second electronic assembly 5 with a display 6 for displaying data and operating elements 7 for programming the tachograph. The front part 2 is held on the base part 1 via a locking connection 8 . The electronic components 3 , 5 are connected to one another via wires 9 designed as flat wires. The wire 9 has an upwardly directed ring 10 and is plugged into connections 11 , 12 of the electronic components 3 , 5 . Between the ring 10 and the connections 11 , 12 , the wire 9 each has a downwardly...

Abstract

In a tachograph for a motor vehicle, an electrical line (9) for connecting two electronic subassemblies (3, 5) is routed to form a loop (10) and has respective run-off edges (13, 14) between the loop (10) and the electronic subassemblies (3, 5). Moisture which condenses on the electrical line (9) is passed from the loop (10) to the run-off edges (13, 14) and can drip off. Damage to the electronic subassemblies (3, 5) is thus avoided.

Description

technical field [0001] The invention relates to a tachograph for a motor vehicle, having a first electronic assembly arranged in a base part, a second electronic assembly arranged in a front part, and wires connecting the above electronic assemblies, wherein the front part The parts are fastened to the base part. Background technique [0002] Such tachographs have a memory device of a chip card for storing data relating to the driver and the motor vehicle, operating elements and a display and are known from practice. The display and operating elements are integrated in the easily accessible front part of the tachograph. In such tachographs it must be ensured that the components of the front part are supplied with the necessary operating voltage and with the information of the system board arranged in the base part. Furthermore, the front part and the base part must be fittable on each other. For this reason, in the known tachograph, flat wires are provided as wires, which...
