Wiring harness and electrical assembly having a wiring harness

1 . A wiring harness for an electrical assembly, wherein the wiring harness is configured to transmit electrical power between two electrical contact points arranged separately from one another, the wiring harness comprising:

an individual conductor, which comprises an electrically insulating layer and forms, along a longitudinal direction of extent of the wiring harness, two connection ends of the wiring harness for electrical contacting of the contact points;

a hollow channel element, which is formed separately from the individual conductor and runs along the longitudinal direction of extent, wherein a respective one of ends of the channel element opens out at a respective one of the connection ends; and

a wiring harness sheath, by way of which the individual conductor and the channel element are jointly sheathed along the longitudinal direction of extent,

wherein the channel element has a dirt trapping device.

2 . The wiring harness according to claim 1 , wherein:

the dirt trapping device has a dirt trapping layer arranged on an inner circumferential side of the channel element.

3 . The wiring harness according to claim 1 , wherein:

the channel element has an additional length portion, because of which the channel element is arranged as wrapping helically around the individual conductor in the wiring harness sheath, at least in a wrapping region.

4 . The wiring harness according to claim 3 , wherein:

the dirt trapping device has the additional length portion.

5 . The wiring harness according to claim 1 , further comprising:

an embedding body, which is arranged in the wiring harness sheath and in which the individual conductor and the channel element are embedded, whereby the wiring harness is fluidically seal-tight within the wiring harness sheath beyond the channel element along the longitudinal direction of extent.

6 . The wiring harness according to claim 1 , wherein:

the channel element has a form stability structure by way of which the channel element is protected from excessive axial and radial deformation.

7 . The wiring harness according to claim 1 , wherein:

the individual conductor projects beyond the channel element at the connection end along the longitudinal direction of extent.

8 . An electrical assembly comprising:

a first electrical contact point and a second electrical contact point, which are electrically connected to one another by the wiring harness according to claim 1 ,

a chamber, which is delimited by a wall element and in which the first electrical contact point is arranged, wherein the second electrical contact point is arranged outside the chamber; and

a passage opening, which penetrates the wall element, wherein the chamber is formed as fluidically seal-tight beyond the passage opening; wherein:

the wiring harness runs through the passage opening,

the passage opening is fluidically sealed off by the wiring harness sheath, while the wiring harness is held in the passage opening; and

one of the connection ends is arranged in the chamber, whereas the other of the connection ends is arranged outside the chamber, so that the chamber and a region outside the chamber are fluidically connected to one another by the channel element for pressure equalization.

9 . The electrical assembly according to claim 8 , further comprising:

a further chamber, in which the second electrical contact point is arranged and which is delimited by the wall element, so that the chamber and the further chamber are fluidically sealed off from one another by the wall element, wherein:

the passage opening opens out on one hand into the chamber and on another hand into the further chamber; and

the other of the connection ends is arranged in the further chamber, so that the chamber and the further chamber are fluidically connected to one another by the channel element for pressure equalization.

10 . A wiring harness for an electrical assembly, wherein the wiring harness is configured to transmit electrical power between two electrical contact points arranged separately from one another, the wiring harness comprising:

an individual conductor, which comprises an electrically insulating layer and forms, along a longitudinal direction of extent of the wiring harness, two connection ends of the wiring harness for electrical contacting of the contact points;

a hollow channel element, which is formed separately from the individual conductor and runs along the longitudinal direction of extent, wherein a respective one of ends of the channel element opens out at a respective one of the connection ends;

a wiring harness sheath, by way of which the individual conductor and the channel element are jointly sheathed along the longitudinal direction of extent; and

an embedding body, which is arranged in the wiring harness sheath and in which the individual conductor and the channel element are embedded, whereby the wiring harness is fluidically seal-tight within the wiring harness sheath beyond the channel element along the longitudinal direction of extent.

11 . A wiring harness for an electrical assembly, wherein the wiring harness is configured to transmit electrical power between two electrical contact points arranged separately from one another, the wiring harness comprising:

an individual conductor, which comprises an electrically insulating layer and forms, along a longitudinal direction of extent of the wiring harness, two connection ends of the wiring harness for electrical contacting of the contact points;

a hollow channel element, which is formed separately from the individual conductor and runs along the longitudinal direction of extent, wherein a respective one of ends of the channel element opens out at a respective one of the connection ends; and

a wiring harness sheath, by way of which the individual conductor and the channel element are jointly sheathed along the longitudinal direction of extent,

wherein the channel element has a form stability structure by way of which the channel element is protected from excessive axial and radial deformation.

12 . The wiring harness according to claim 2 , wherein the dirt trapping layer is at least one of:

a magnetic and/or magnetizable material layer;

adhesively formed; or

configured as a hook tape of a hook-and-loop fastener.
