Definitions
- the invention relates to an electrically conductive cable for connecting consumers and one
- Power supply device in particular in connection with a vehicle electrical system, according to the preamble of the main claim.
- the connection of consumers in a voltage supply system, for example in a vehicle electrical system, to the voltage supply, for example the battery or to a plug, which in turn is connected to the battery, is usually carried out today via cable harnesses.
- Such cable harnesses comprise a multiplicity of electrical lines which are parallel to one another and are jointly connected to the plug or the battery or a generator, a single load or a single electrical consumer being connected on the other side of the line.
- the cable harnesses usually contain lines with different cross-sections, the cross-section being adapted to the power consumption of the consumer, so that high-current consumers are supplied via lines with a large cross-section, while consumers with low power consumption can be supplied via thinner cables.
- the voltage supply system for example the vehicle electrical system
- only a small part of the consumers is switched on, so that most of the lines carry no current at all.
- the electrically conductive cable according to the invention with the features of claim 1 has the advantage that maximum utilization of the cable is possible since only minimal line sections are without current. It is furthermore advantageous that a reduction in line losses can be achieved, since the maximum cable cross section is also available for small currents. It is also advantageous that no insulation of individual wires of the cable harness is required, so that a saving in material, for example copper, is possible since the design of the cross section can be optimized and is generally less than with individual cables. As a result of the smaller cross section, a more flexible installation is possible and it is advantageous to save
- the saving in insulation for individual cables and the saving in material make it possible to advantageously reduce the weight.
- These advantages are achieved by designing the cable in such a way that the largest cable cross section occurs on the connection side which is connected to the voltage supply or to a plug which leads to the voltage supply.
- This cable cross section extends over a first area, at the end of which the first branches appear. In the next section, the cable has a smaller cross-section and in the section after next, after further branches, the cross-section of the cable is further reduced.
- These semiconductors are advantageously designed as high-side switches, which enables direct mounting of the semiconductors on the conductor material, for example the copper, so that it can also be used as a heat sink.
- the semi-conductor-switched cable branches mean that fuses can be omitted if they are replaced by intelligent power amplifiers. It is possible to switch off partial branches, for example in the event of generator overload and. Part of the on-board electrical system can thus advantageously be decoupled directly if problems with the energy supply make this necessary.
- Another advantage of the invention results from the cable branch protection through minimum cross-section and the generally possible saving of fuses.
- Figure 1 shows a conventional wire harness.
- FIG. 1 shows a conventional cable harness 10, which consists of four sub-areas A, B, C, E and is connected to a common plug 11, which is connected via a connection 12 to a voltage supply unit 13, for example a battery of a motor vehicle or a generator stands .
- the wiring harness 10 consists of 9 individual lines 10a, b,... I, which may have different cross sections. These lines or single wires are routed in parallel and lead to centrally controlled loads 1 to 8. Two of the loads are sometimes combined, namely 1 and 2, 3 and 4, and 6 and 7. 8 is a single load, the load 5 has a redundant one Supply via two separate single wires.
- the load 5 can be an electrical consumer, its functional path is particularly relevant to safety, for example an electric brake or a control unit for an anti-lock control.
- FIG. 2 shows a first exemplary embodiment of the invention and this exemplary embodiment has the same consumers 1 to 8.
- the wiring harness is in turn connected to a common plug 11, which is connected to the voltage supply device 13 via a connection 12, or is connected directly to the battery, the generator or a distributor.
- the cable harness 14 consists of a cable trunk, in which the single wire cross sections in the areas A, B and C are combined.
- the area of the wire harness is largest in area A, the second largest in area B and the third largest in area C.
- area E as in the example according to FIG. 1, there is only a single wire.
- Overload-protected power amplifiers A 1/2, B 3/4/5 and C / 5/6/7/8 are installed between the wiring harness and the loads or consumers 1 to 8. These overload-protected output stages are controlled externally, for example by a central control unit. You switch the loads assigned to them to the relevant area of the wiring harness. The overload-protected output stages also ensure that no short circuits or the like occur.
- the load 5 is supplied redundantly via different wiring harness branches B and C and the associated overload-protected output stages.
- This redundant supply via different wiring harness branches makes it particularly safe and reliable Power supply guaranteed even in the event of malfunctions.
- FIG. 3 shows a second exemplary embodiment of the invention with a cable harness 15 which corresponds to the exemplary embodiment according to FIG. 2 up to area B.
- a cable harness 15 which corresponds to the exemplary embodiment according to FIG. 2 up to area B.
- an overload-protected output stage Bl which is connected to the output stage B3 / 4/5 via a further wiring harness branch or area Bl a.
- the wiring harness branch B leads via the wiring harness branch C with a thinner cross section to the overload-protected switch B5 / 6/7/8.
- Both the loads 6 and 7 and the load A are connected to this overload-protected switch via the single wire E as well as the load 5, which is also connected to the overload-protected switch Bl via the overload-protected switch B3 / 4/5 and the wiring harness Bl a stands. Consumers 3 and 4 are also supplied via the overload-protected switch B3 / 4/5.
- the adaptation of the cross sections of the wiring harness trunk A and the wiring harness branches Bl and C can in turn be determined on the basis of the expected consumption performance of the individual consumers. With the cable harness shown in Figure 3 with cable trunk and cable branches, the potential savings potential for the conductor material is fully exploited.
- a particularly cost-effective solution for the construction of the cable harness can be achieved in that the overload-protected semiconductor switches are shifted into the actuators and at the branches of the individual wires
- the wire or the cable branch can be run directly over a short section as a fuse. If a short circuit occurs, the single wire would have to be attached to the cable trunk or the cable branch using a securing element. This saves fuses and contacts that are currently required in wiring harnesses in the motor vehicle, in which each consumer is individually protected, a large number of these fuses never becoming active in the normal operating state.
