[0031] A wiring harness 1000 according to embodiments of the present disclosure is described below with reference to FIG. 1 and FIG. 2. The wiring harness 1000 may be applicable to an electronic device and is configured to connect a battery portion to a host. The electronic device may be a head-mounted device, for example, an all-in-one VR machine.

[0032] The wiring harness 1000 according to the embodiments of the present disclosure includes signal lines 1, grounding wires 2 and power cables 3. Each signal line 1 includes a plurality of signal conductors 10. Each grounding wire 2 includes a plurality of grounding conductors 20. Each power cable 3 includes a plurality of power conductors 30. The signal lines 1, the grounding wires 2 and the power cables 3 are disposed in the same outer sheath 4, and are sequentially arranged in a first direction. In some examples of the present disclosure, the signal lines 1, the grounding wires 2 and the power cables 3 are sequentially arranged in the width direction of the wiring harness 1000. In the length direction of the wiring harness 1000, two ends of the wiring harness 1000 are connected to the battery portion and the host, respectively.

[0033] It should be noted that a power cable of a wiring harness in the related art is provided with a power conductor and a power outer sheath wrapping the power conductor; a signal line of the wiring harness in the related art is provided with a signal conductor and a signal outer sheath wrapping the signal conductor; a grounding wire of the wiring harness in the related art is provided with a grounding conductor and a grounding outer sheath wrapping the grounding outer sheath; and the wiring harness in the related art has larger dimensions. As a result, dimensions of an electronic device provided with the wiring harness are larger.

[0034] In the wiring harness 1000 according to the embodiments of the present disclosure, the signal lines 1, the grounding wires 2 and the power cables 3 share an outer sheath 4. In a case that a structural space is not changed, the wiring harness 1000 in this embodiment of the present disclosure may reserve a larger wiring space, so that more wires can be disposed for larger current, so that a current flow capability of the wiring harness 1000 is improved. Compared with a wiring harness in the related art, the wiring harness 1000 according to the embodiments of the present disclosure may have a reduced wiring space and decreased overall dimensions. This is conducive to overall miniaturization of an electronic device with the wiring harness.

[0035] It should be noted that the shape, the width, the thickness, and the like of the outer sheath 4 in the embodiments of the present disclosure may be set according to an actual space requirement. This is not specifically limited herein.

[0036] In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 2, each signal line 1 further includes a shielding layer 11 wrapping outer sides of the plurality of signal conductors 10. It may be understood that in this case, the entire outer sheath 4 wraps the shielding layer 11. Therefore, due to arrangement of the shielding layer 11, an external signal can be further prevented from interfering with the signal conductor 10 to ensure that the signal conductor 10 can transmit a signal without any interference as far as possible. In some other examples of the present disclosure, the entire outer sheath 4 may be provided as a shielding member, so that interference to signals of the grounding wires 2, the signal lines 1 and the power cables 3 can be reduced.

[0037] It should be noted that because currents transmitted in the power cable 3, the grounding wire 2, and the signal line 1 may be different, cross-sectional areas of the power conductor 30, the grounding conductor 20, and the signal conductor 10 may be defined based on actually transmitted currents. Therefore, in some embodiments of the present disclosure, at least two of the signal conductor 10, the grounding conductor 20 and the power conductor 30 have different cross-sectional areas. In other words, all of the cross-sectional areas of the signal conductor 10, the grounding conductor 20 and the power conductor 30 may be different from each other; or the cross-sectional areas of the grounding conductor 20 and the power conductor 30 are the same; or the cross-sectional area of the signal conductor 10 is different from the cross-sectional areas of both the grounding conductor 20 and the power conductor 30. This may be defined according to actual conditions. Therefore, the size of the wiring harness 1000 can be further reduced.

[0038] It should be noted that compared with the signal line 1, the power cable 3 and the grounding wire 2 are required to transmit larger currents, so that as shown in FIG. 1 and FIG. 2, in some embodiments of the present disclosure, the cross-sectional area of the signal conductor 10 is the smallest. Therefore, the size of the wiring harness 1000 can be further reduced.

[0039] In some specific examples of the present disclosure, the cross-sectional area of the signal conductor 10 is smaller than the cross-sectional area of the grounding conductor 20; and/or the cross-sectional area of the signal conductor 10 is smaller than the cross-sectional area of the power conductor 30. Therefore, the size of the wiring harness 1000 can be further reduced. It should be noted that types of the power conductor 30, the signal conductor 10 and the grounding conductor 20 may be defined according to actual conditions. This is not specifically limited herein.

[0040] As shown in FIG. 1 and FIG. 2, in some examples of the present disclosure, the cross-sectional areas of the grounding conductor 20 and the power conductor 30 are the same.

[0041] In some embodiments of the present disclosure, as shown in FIG. 1, a plurality of power cables 3 is provided, and is disposed side by side. In other words, the plurality of power cables 3 is disposed next to each other side by side, that is, neither grounding wire 2 nor signal line 1 is disposed between adjacent power cables 3, so that conductor impedance can be lower, current flowing the wiring harness 1000 can be increased, and the size of the wiring harness 1000 can be reduced.

[0042] As shown in FIG. 1 and FIG. 2, in some examples of the present disclosure, a plurality of grounding wires 2 is provided, and is disposed side by side. In other words, the plurality of grounding wires 2 is disposed next to each other side by side, that is, neither power cable 3 and nor signal line 1 is disposed between adjacent grounding wires 2, so that conductor impedance can be reduced, and the size of the wiring harness 1000 can be reduced. Further, as shown in FIG. 1 and FIG. 2, a plurality of signal lines 1 is provided. The signal lines 1 in the same network are disposed side by side, that is, neither grounding wire 2 and nor power cable 3 is disposed between adjacent signal lines 1 in the same network. It should be noted that in description of the present disclosure, signal lines 1 in the same network transmit the same information signal. For example, relative to the host, the information signal includes an input information signal and an output information signal. In this case, signal lines 1 transmitting the same input information signal may be disposed side by side; and signal lines 1 transmitting the same output information signal may be disposed side by side.

[0048] As shown in FIG. 1 and FIG. 2, in some embodiments of the present disclosure, the power cable 3 includes a second filling member 31. The plurality of power conductors 30 is arranged into a circular ring surrounding the second filling member 31; and/or the grounding wire 2 includes a third filling member 21, wherein the plurality of grounding conductors 20 is arranged into a circular ring surrounding the third filling member 21.
