[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model embodiment provides a car instrument panel atmosphere light harness, including

[0028] An electric wire 2 and an outer sheath 3 covering the outer side of the electric wire 2, wherein a metal bracket 4 is further provided on the inner side of the outer sheath 3;

[0029] The outer sheath 3 includes a foam tube 31 , a wire-releasing opening 32 is provided on the side of the foam tube 31 , and the wire 2 is placed inside the foam tube 31 , and an inner lining installation groove 33 for placing the metal bracket 4 is provided on the inner side of the foam tube 31 .

[0030] In this embodiment, the metal support 4 is mainly composed of flexible struts 41 and a connecting ring 42 , and the flexible struts 41 are fixed on the outside of the connecting ring 42 in a ring array.

[0031] In this embodiment, the electric wire 2 passes through the inner side of the foam tube 31 , and a male connector 1 and a female connector 5 are respectively provided at both ends of the electric wire 2 .

[0032] In this embodiment, two groups of metal brackets 4 are provided and symmetrically distributed on the inner side of the outer sheath 3 .

[0033] In this embodiment, an elastic locking piece 11 is integrally provided on the male connector 1 , and a terminal pin 12 is interference-fitted on the inner side of the male connector 1 .

[0034] In this embodiment, the female connector 5 is integrally provided with a positioning buckle 51 to facilitate connection with the ambient light LED module.

[0035] By adopting the above technical solution, before installation, the wire 2 is placed in the foam tube 31 through the wire release opening 32, and the two ends of the wiring harness are connected to the vehicle wiring harness end and the ambient light LED module through the male connector 1 and the female connector 5 respectively. During driving, the foam tube 31 can reduce the noise generated by friction and improve driving comfort.

[0036] In the above scheme, the sound generated by friction welding is reduced by the sound absorption effect of the foam tube 31 itself. There are many small holes on the surface of the foam tube 31. When the sound enters the small holes, it will be randomly reflected in the inner wall which is a bit like a sponge in structure until most of the energy of the sound wave is consumed.

[0037] In this embodiment, the flexible support rod 41 and the connecting ring 42 are respectively inserted into the inner side of the liner installation groove 33, so that the staff can easily replace the damaged flexible support rod 41 and the connecting ring 42.

[0038] In this embodiment, the flexible support rod 41 is made of an aluminum alloy rod, and the outer sheath 3 can be bent according to the position of the wire harness to reduce the contact between the wire harness and other components.

[0039] In this embodiment, the end of the electric wire 2 is inserted into the inner side of the terminal pin 12, and the terminal pin 12 and the electric wire 2 are interference fit.

[0040] In this embodiment, a conductive sheet is provided on the inner side of the female connector 5 , and the conductive sheet is interference fit with the side of the wire 2 away from the terminal pin 12 .

[0041] The working principle of the utility model is: before use, the terminal is first crimped to the end of the wire 2, and then the terminal is respectively fixed into the male connector 1 and the female connector 5 by interference fit, and then the wire 2 is placed in the foam tube 31 through the wire release opening 32 to protect the wire 2 and reduce the noise generated by the friction between the wire harness and other components, and then the wire harness is placed in the instrument panel installation position, and is connected to the vehicle wiring harness end and the ambient light LED module through the male connector 1 and the female connector 5 respectively, and the outer sheath 3 is bent according to the position of the wire harness, and the flexible support rod 41 on the inner side of the outer sheath 3 will also be bent by force to reduce the friction between the wire harness and other structures, and the flexible support rod 41 and the connecting ring 42 will also protect the wire 2 to prevent the wire harness from being damaged after being squeezed.
