Problems solved by technology
[0013] As shown in Figure 1, although the use of a shunt connector allows for a certain rationalization (at least for ground cables) in which there are still cables extending between the input electrical connector and the circuit board in a haphazard manner with branches and curves, which can lead to failure or damage

Embodiment Construction
[0023] see figure 2 , reference numeral 10 generally denotes a wiring system for connecting common electrical cables 22 (such as ground cables) and circuit board cables 23 to 29 (such as power supply cables) to a plurality of electronic printed circuit boards 12 to 18, At least some of these circuit board cables must be connected to a single corresponding circuit board. In other words, at least some of the circuit boards receive their own circuit board signals independently of each other.
[0024] The cabling system 10 includes a cable harness 21 , such as a cable harness from an input electrical connector 20 . The cable harness 21 includes a common electric cable 22 and a plurality of circuit board cables 23 to 29 .
[0025] The wiring system 10 also includes a plurality of insulation piercing multi-pole connectors 30 to 36 arranged successively along the cable bundle. Each of said multi-pole connectors 30 to 36 is adapted to be connected to a respective circuit board 12 t...

The present invention relates to a wiring system and method for connecting a common electrical cable (22), such as a ground cable, and corresponding circuit board conductors (23 to 29) to a plurality of electronic printed circuit boards, said common electrical cable (22), such as a ground cable, so The above-mentioned circuit board wires such as power supply cables. The system comprises a cable harness (21) and a plurality of multi-pole insulation piercing connectors (30 to 36) arranged successively along said cable harness. Each of the connectors is adapted to receive a common electrical cable, a circuit board cable that is connected to a corresponding circuit board, and a circuit board cable that must be connected to a subsequent connector, and is adapted to connect the common electrical cable to the necessary circuit board cable. The circuit board wires connected to the subsequent connectors are passed to the subsequent insulation piercing connectors.
Description
technical field [0001] The present invention relates to a wiring system, in particular for providing independent power supplies to a plurality of electronic printed circuit boards, such as circuit boards of motor vehicle lights. Background technique [0002] Many electrical or electronic devices comprise a plurality of printed circuit boards spaced apart and sometimes arranged parallel to each other, each printed circuit board having to be equipped with corresponding power supply, ground and possibly other signals, eg for diagnostics. [0003] For example, in the same motor vehicle light, there are multiple printed circuit boards for lights with different functions, such as position lights, turn lights, stop lights, and so on. An electrical connector (referred to in the jargon as an "automotive connector") is secured to the lamp, to which a harness of power, ground and diagnostic cables is connected. The different circuit boards of the lamps have to be connected to this con...
