When producing the electrical assembly, for example first at least the first chamber of the electrical assembly may be provided without a pressure equalizing element, the passage opening not being able to serve as such a pressure equalizing element during operation of the electrical assembly because, as intended, the passage opening is blocked against a fluid, that is to say air, flowing through it, in that the wiring harness is fitted in the passage opening. Nevertheless, because of the wiring harness, venting of the first chamber, that is to say the pressure equalization between the first chamber and the region lying outside the first chamber, is made possible, in that the fluid, for example the air, can flow through the channel element between the first chamber and the region lying outside the first chamber. In this way the electrical assembly can be produced particularly easily and/or involving little effort, because—apart from the wiring harness—no separate pressure equalizing element has to be produced. In this case, the wiring harness is suitable in particular as a retrofitting solution for retrofitting a pressure equalizing possibility for the first chamber.

Provided in a further refinement of the electrical assembly is a further, second chamber, for example a second machine chamber, in which the second electrical contact point is arranged and which is delimited by the wall element, so that the chambers are fluidically sealed off from one another by way of the wall element. In this case, the passage opening opens out on the one hand into the first chamber and on the other hand into the further or second chamber. Furthermore, the other of the connection ends of the wiring harness is arranged in the further or second chamber, so that the chambers are fluidically connected to one another by way of the channel element for pressure equalization. In this case, it is provided in particular that the two chambers are fluidically connected to one another only or exclusively by way of the wiring harness. In other words, the two chambers are fluidically sealed off from one another beyond the channel element or wiring harness.

The invention relates furthermore to a motor vehicle which is equipped with the wiring harness presented above or with the electrical assembly presented above. Features, advantages and advantageous refinements of the wiring harness according to embodiments of the invention and of the electrical assembly according to embodiments of the invention should be regarded as features, advantages and advantageous refinements of the motor vehicle according to embodiments of the invention, and vice versa.

Further features of the invention may emerge from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description and the features and combinations of features shown in the description of the figures below and/or in the figures alone can be used not only in the respectively stated combination but also in other combinations or alone without departing from the scope of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS

In the figures, elements that are the same or functionally the same are provided with the same designations.

A wiring harness 1 and an electrical assembly 2 are presented below in a joint description. For this purpose, FIG. 1 shows in a perspective and partially sectional view a portion of the wiring harness 1 which has a channel element 3. If the electrical assembly 2 (shown in part in FIG. 2) has been produced in such a way that it is ready for use, the electrical assembly 2 has the wiring harness 1. In this case, the wiring harness 1 is designed for transmitting electrical power, that is to say electrical voltage and/or electrical current, between two electrical contact points (not shown) arranged or formed separately from one another. For this purpose, the wiring harness 1 has an individual conductor 4, in the present example two individual conductors 4, which have a respective core 5 of an electrically conducting or electrically conductive material, for example metal. The wiring harness may have more than two individual conductors.

The respective individual conductor 4 comprises an electrically insulating layer 6, the respective core 5 and the respective electrically insulating layer 6 being connected to one another in such a way that a fluid, for example air, is blocked from passing through between the respective core 5 and the respective electrically insulating layer 6. In other words, the respective individual conductor 4 is formed as fluidically seal-tight along its longitudinal direction of extent 7. In the stretched state of the wiring harness 1, a longitudinal direction of extent 8 of the wiring harness 1 and the longitudinal direction of extent 7 of the individual conductor 4 coincide or are parallel to one another. A connection end 10 of the wiring harness 1 is formed by a respective end 9 of the respective individual conductor 4. In this case, the connection end 10 of the wiring harness 1 is designed to be brought into electrically conducting or conductive contact with the contact points, so that an electrically conducting or conductive connection is established between the wiring harness 1, in particular the corresponding individual conductor 4, and the corresponding contact point.

The channel element 3 is of a hollow form and runs along the longitudinal direction of extent 8 of the wiring harness 1, an open end 11 of the channel element 3 opening out at the connection end 10. Expressed a different way, the end 11 of the channel element 3 is arranged in the region, in particular the proximity, of the connection end 10. To this extent it should be understood that the connection end 10 is a region or space which encloses both the corresponding end 9 of the corresponding individual conductor 4 and the end 11 of the channel element 3.

Along the longitudinal direction of extent 8 of the wiring harness 1, the channel element 3 may be arranged parallel to the individual conductors 4. In the present example it is provided that the wiring harness 1 has a wrapping region 12, in which the channel element 3 wraps around at least one of the individual conductors 4 or a number of the individual conductors 4. In this case, the channel element 3 is arranged helically or like a helix, at least in the wrapping region 12, so that the individual conductor(s) 4 is/are wrapped around helically by the channel element 3.
