[0035] like Figures 1 to 6 As shown, an exemplary embodiment of the utility model provides a threading device for a vehicle wiring harness. The threading device includes:

[0036] A threading member 1, wherein the threading member 1 is provided with a threading hole, and the threading hole passes through the threading member 1 along a first direction, wherein a threading opening 11 communicating with the threading hole is provided on the side of the threading member 1;

[0037] The lead sleeve 2 is sleeved on the threading member 1 along a first direction, and a threading notch 21 is provided on the lead sleeve 2 to be aligned with the threading opening 11, wherein the lead sleeve 2 can rotate around the first direction to achieve alignment or misalignment of the threading notch 21 with the threading opening 11.

[0038] In this embodiment, the threading device includes a threading member 1 and a lead sleeve 2, wherein the threading member 1 is provided with a threading hole, and the threading hole passes through the threading member 1 along a first direction, that is, the first direction can be the length extension direction of the threading member 1, and a threading opening 11 connected to the threading hole is also provided on the side of the threading member 1, and the length of the threading opening 11 is consistent with the length of the threading hole; the lead sleeve 2 is sleeved on the threading member 1, and the lead sleeve 2 is arranged along the first direction, and a threading notch 21 aligned with the threading opening 11 is provided on the lead sleeve 2, and when the lead sleeve 2 rotates around the threading member 1, the alignment setting or misalignment setting between the threading notch 21 and the threading opening 11 can be achieved. Based on the above technical solution, the alignment setting or misalignment setting of the threading notch 21 and the threading opening 11 is utilized to effectively improve the assembly efficiency of the vehicle wiring harness, and at the same time, the control of the winding direction of the wiring harness can be achieved, which is convenient for the assembly of the wiring harness.

[0039] During use, the lead sleeve 2 is first rotated to align the threading opening 11 and the threading notch 21, and then the wire harness 3 is placed in the threading member 1. After the wire harness 3 is placed, the lead sleeve 2 is rotated to stagger the threading opening 11 and the threading notch 21, so that the wire harness 3 can be prevented from being separated from the threading member 1. Then the wire harness protective cover 4 is passed through the threading device, and finally the wire harness protective cover 4 is sleeved on the outside of the wire harness. In the sleeve connection process, one end of the threading member 1 can be located outside the wire harness protective cover 4, and the other end can be located inside the wire harness protective cover 4.

[0040] It should be noted that the threading device can be used for the assembly of vehicle wiring harnesses, for example, a wiring harness protective sleeve with an opening is sleeved on the wiring harness, etc. The vehicle may include but is not limited to components such as wheels, steering wheels, and power systems, and the vehicle may be an electric vehicle, a hybrid vehicle, etc. The vehicle may be a sedan, SUV, MPV, or other suitable vehicle. Among them, the wiring harness protective sleeve with an opening may include but is not limited to a corrugated tube made of thermoplastic plastic, a high and low temperature resistant hose, and a flame retardant threading tube, etc.

[0041] Further, if Figure 2 As shown, the threading member 1 includes a threading body 12 and a hand-held protrusion 13;

[0042] The threading hole and threading opening 11 are arranged on the threading body 12, and the threading body 12 comprises a first end and a second end, wherein the cross-sectional dimension of the first end is greater than the cross-sectional dimension of the second end;

[0043] The hand-holding protrusion 13 is a symmetrical structure and is disposed on the outer edge of the first end. The threading opening 11 extends to the hand-holding protrusion 13 .

[0044] In this embodiment, in order to facilitate operation, a hand-held protrusion 13 is provided on the first end of the threading body 12. The hand-held protrusion 13 is mainly used as a carrier for the operator to conveniently apply force to the threading body 12 during manual operation. The threading body 12 includes a first end and a second end, and the cross-sectional size of the first end is larger than the cross-sectional size of the second end. The first end is connected to the hand-held protrusion 13, so a large size makes it easier to operate, and the second end needs to be inserted into the harness protective cover, so a small size makes it less likely to fall out of the harness protective cover 4.

[0045] Further, if Figure 2 As shown, the threading body 12 is a truncated cone structure extending along a first direction.

[0046] In this embodiment, in order to reduce manufacturing costs and reduce the resistance encountered by the harness protective cover during the installation process, the threading body 12 is set as a truncated cone structure. The threading hole is opened on the truncated cone structure, and the axis of the threading hole completely coincides with the central axis of the truncated cone structure. The direction of the central axis of the truncated cone structure is the same direction or opposite direction to the first direction.

[0047] Further, if Figure 1 and Figure 2 As shown, the threading body 12 is provided with a first limiting protrusion 14 and a second limiting protrusion 15, and the threading opening 11 extends to the first limiting protrusion 14 and the second limiting protrusion 15;

[0048] The first limiting protrusion 14 is located on the outer edge of the second end;

[0049] The second limiting protrusion 15 is located between the first end and the second end;

[0050] The first limiting protrusion 14 and the second limiting protrusion 15 contact different ends of the lead sleeve 2 at the same time.

[0051] In this embodiment, in order to improve the efficiency of threading, the position of the lead sleeve 2 on the threading body 12 can be fixed or limited. A first limiting protrusion 14 and a second limiting protrusion 15 are provided on the threading body 12, the first limiting protrusion 14 is located on the outer edge of the second end, the second limiting protrusion 15 is located between the first end and the second end, the lead sleeve 2 is sleeved on the threading body 12, and one end of the lead sleeve 2 contacts the first limiting protrusion 14, and the other end contacts the second limiting protrusion 15. The first limiting protrusion 14 and the second limiting protrusion 15 play a clamping role on the lead sleeve 2, avoiding the situation of low threading efficiency caused by the random movement of the lead sleeve 2 during the threading process.

[0052] Further, if Figure 2 As shown, the threading body 12, the hand-held protrusion 13, the first limiting protrusion 14 and the second limiting protrusion 15 are an integrated structure.

[0053] In this embodiment, in order to facilitate manufacturing and reduce processing costs and cycles, the threading body 12, the hand-held protrusion 13, the first limiting protrusion 14 and the second limiting protrusion 15 are configured as an integrated structure.

[0054] Further, if Figure 3 As shown, a rotation protrusion 22 is provided on the outer peripheral wall of the lead sleeve 2, and the rotation protrusion 22 is located on the outer surface of the side wall of one of the threading notches 21.

[0055] In this embodiment, in order to facilitate the rotation of the lead sleeve 2, a rotating protrusion 22 is provided on the outer peripheral wall of the lead sleeve 2. The operator rotates the lead sleeve 2 by rotating the protrusion 22, thereby realizing the misalignment of the lead opening and the lead notch. In order to facilitate identification by the operator, the rotating protrusion 22 is provided on the surface of one side wall of the threading notch 21.

[0056] Further, if Figure 3 As shown, the free end of the rotating protrusion 22 is extended in the opposite direction to the first direction.

[0057] In this embodiment, in order to prevent the rotating protrusion 22 from occupying a relatively large space, the free end of the rotating protrusion 22 is arranged to extend in the opposite direction to the first direction.

[0058] Further, if Figure 3 and Figure 5 As shown, a limiting opening which is engaged with the first limiting protrusion 14 is provided on the free end of the rotating protrusion 22 .

[0059] In this embodiment, in order to avoid interference between the lead sleeve 2 and the first limiting protrusion 14 during the rotation of the lead sleeve 2, a limiting opening is opened on the free end of the rotating protrusion 22, the first limiting protrusion 14 is inserted into the limiting opening, and there is a gap between the inner wall of the limiting opening and the outer wall of the first limiting protrusion 14.

[0060] Further, if Figures 3 to 6 As shown, a guide protrusion 23 is further provided on the outer peripheral wall of the lead sleeve 2, and the free end of the guide protrusion 23 is extended toward the first direction.

[0061] In this embodiment, since the wire harness protective cover 4 is tubular in its natural state, in order to allow the threading device to smoothly enter the wire harness protective cover 4, a guide protrusion 23 is provided on the outer peripheral wall of the lead sleeve 2, and the guide protrusion 23 enters the wire harness protective cover 4 before the second end of the threading body 12, and the wire harness protective cover 4 is opened in the form of a cut, and then the second end of the threading body 12 can smoothly enter the wire harness protective cover.

[0062] Further, if Figure 5As shown, the connecting end of the guide protrusion 23 and the connecting end of the rotating protrusion 22 are arranged in a circumferentially symmetrical form, wherein the reference object of the circumferential symmetry is the outer peripheral wall of the lead sleeve 2 .

[0063] In this embodiment, in order to facilitate the operation and to prevent the lead sleeve 2 from detaching from the threading body 12 to the greatest extent during the threading process, the guide protrusion 23 and the rotating protrusion 22 are set to a symmetrical form, which is a circularly symmetrical form, and the reference object of the circular symmetry is the outer peripheral wall of the threading body 12.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
