A wiring harness protection device for motorcycles

Abstract

This invention relates to the field of wiring harness protection technology, and in particular to a wiring harness protection device for motorcycles. The device includes a corrugated tape, one end of which is wound around a roller, and the other end is spirally wound along the length of the wiring harness. Adjacent turns of the corrugated tape interlock to form a circumferentially closed cylindrical structure, thereby enclosing the wiring harness within the cylindrical structure. Compared to the corrugated tubes with a circumferential seam on one side used in the prior art, the cylindrical structure formed by the spiral winding of the corrugated tape in this invention, being circumferentially closed, prevents the wiring harness from detaching from the corrugated tape when it is subjected to force and radially displaced relative to the wiring harness inside. This prevents the wiring harness from coming into contact with and wearing down components such as the metal edges of the frame due to detachment. Therefore, the cylindrical structure formed by the spiral winding of the corrugated tape in this invention provides better protection for the wiring harness.

Description

Technical Field

[0001] This invention relates to the field of wiring harness protection technology, and in particular to a wiring harness protection device for motorcycles. Background Technology

[0002] A motorcycle contains many wiring harnesses, such as the positive power wire, the negative ground wire, the light wire, the horn wire, and the sensor wire. In order to organize and protect these numerous wiring harnesses, protective devices need to be installed on the outside of the wiring harnesses during the motorcycle manufacturing process.

[0003] Currently, the most commonly used wire harness protection device is a corrugated tube. To facilitate the installation of the wire harness inside the corrugated tube, a mounting seam is usually cut along one side of the tube, extending along the tube's axis and penetrating the tube. However, during motorcycle operation, the corrugated tube inevitably comes into contact with components such as the metal edges of the frame, engine housing, and shock absorbers. At this time, the corrugated tube is prone to displacement relative to the wire harness inside it, causing the wire harness inside the corrugated tube to come out from the mounting seam. This results in the wire harness losing the protective function of the corrugated tube. Summary of the Invention

[0004] Therefore, it is necessary to provide a motorcycle wiring harness protection device to address the problems existing in current wiring harness protection devices, in order to solve the problem that the wiring harness inside the corrugated tube is prone to coming out from the installation seam.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A wiring harness protection device for a motorcycle includes:

[0007] The corrugated tape is wound on the belt roller at one end and spirally wound along the length of the wire bundle at the other end. Adjacent turns of the corrugated tape are interlocked to form a circumferentially closed cylindrical structure, which in turn encloses the wire bundle inside the cylindrical structure.

[0008] Steel wires are embedded at the junction of the crests and troughs of the corrugated belt, and the steel wires extend along the length of the corrugated belt.

[0009] Preferably, the width of the interlocking between two adjacent corrugated strips is at least three-half the wavelength of the corrugated strip.

[0010] Preferably, a wiring harness protection device for a motorcycle further includes a multi-port guide sleeve, which is fitted onto the bifurcation point of the wiring harness.

[0011] After the work reaches the bifurcation point, the corrugated belt spirally wraps around the outside of the multi-pass guide sleeve.

[0012] Preferably, a wiring harness protection device for a motorcycle further includes a double-pass guide sleeve, which is slidably sleeved on the outside of the wiring harness;

[0013] During operation, the corrugated tape is spirally wound around the outside of the double-pass guide sleeve. When the outside of the double-pass guide sleeve is fully wrapped with corrugated tape, the double-pass guide sleeve moves a preset distance along the length of the wire harness, and then the corrugated tape continues to be spirally wound around the outside of the double-pass guide sleeve.

[0014] Preferably, both the double-pass guide sleeve and the multi-pass guide sleeve include a male part and a female part, and the male part and the corresponding female part are snapped together to form a ring.

[0015] Preferably, the corrugations have multiple lines;

[0016] When working on the main section of the wire harness, multiple corrugated strips are arranged side by side along their width direction, and adjacent corrugated strips are interlocked with each other and spirally wound along the length direction of the main section of the wire harness.

[0017] After working from the main section of the harness to the branching point, multiple corrugated strips are disengaged to form multiple sets of corrugated strips that match the number of branching sections of the harness. Each set has at least one corrugated strip, and the multiple sets of corrugated strips correspond one-to-one with the multiple branching sections of the harness, and are spirally wound along the length direction of the corresponding branching section of the harness.

[0018] Preferably, a wiring harness protection device for a motorcycle further includes a connector for actuating the double-pass guide sleeve along its own axis.

[0019] Preferably, a wiring harness protection device for a motorcycle further includes a grip portion connected to a connector for pushing a double-pass guide sleeve along its own axis via the connector.

[0020] Preferably, the gripping part is also connected to the belt roller to drive the belt roller to move synchronously.

[0021] The beneficial effects of this invention are:

[0022] This invention incorporates a corrugated tape, which is wound along the length of the wire harness to form a circumferentially closed cylindrical structure, enclosing the wire harness within the cylindrical structure. Compared to the corrugated tubes used in the prior art with an installation slot on one side of the circumference, the cylindrical structure formed by the spiral winding of the corrugated tape in this invention is circumferentially closed. Therefore, when the cylindrical structure formed by the corrugated tape is subjected to force and radially displaces relative to the wire harness inside, the wire harness will not come out of the corrugated tape. This prevents the wire harness from coming into contact with the metal edges of the vehicle frame and causing wear due to contact. Therefore, the cylindrical structure formed by the spiral winding of the corrugated tape in this invention provides better protection for the wire harness. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0041] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] like Figures 1 to 11 As shown, a motorcycle wiring harness protection device includes a corrugated belt 100, one end of which is wound around a belt roller 110, and the other end is spirally wound along the length of the wiring harness 500. Adjacent turns of the corrugated belt 100 are interlocked to form a circumferentially closed cylindrical structure, thereby enclosing the wiring harness 500 inside the cylindrical structure.

[0044] In use, the operator first secures the wire harness 500, then fixes the end of the corrugated belt 100 away from the belt roller 110 (e.g., with glue or tape) to the end of the wire harness 500. The belt roller 110 then moves spirally around the axis of the wire harness 500, causing the corrugated belt 100 to spirally wind along the length of the wire harness 500. When the corrugated belt 100 spirally winds along the length of the wire harness 500, the pitch of the spiral movement trajectory of the corrugated belt 100 should be less than the width of the corrugated belt 100 to ensure that adjacent turns of the corrugated belt 100 can interlock. This spiral winding of multiple turns of corrugated belt 100 forms a circumferentially closed cylindrical structure, enclosing the wire harness 500 within the cylindrical structure. This is different from the circumferentially open-sided structure used in existing technologies. The corrugated tube with an installation seam, the cylindrical structure formed by the spiral winding of the corrugated tape 100 in this invention is circumferentially closed. Therefore, when the cylindrical structure formed by the corrugated tape 100 is subjected to force and radially displaces relative to the wire harness 500 inside it, the wire harness 500 will not come out of the corrugated tape 100. This prevents the wire harness 500 from coming out and coming into contact with the metal edge of the frame and other parts, thus preventing wear. Therefore, this invention has a better protection effect on the wire harness 500. After the corrugated tape 100 is spirally wound to the other end of the wire harness 500, the worker cuts the corrugated tape 100, so that the corrugated tape 100 wound on the outside of the wire harness 500 and the corrugated tape 100 wound on the belt roller 110 are separated from each other. Finally, the end of the corrugated tape 100 spirally wound to the other end of the wire harness 500 is fixed to the upper part of the wire harness 500.

[0045] It is understood that the corrugated belt 100 used in this invention has a dual function. During the spiral winding process of the corrugated belt 100, by making the pitch of the spiral movement trajectory of the corrugated belt 100 smaller than the bandwidth of the corrugated belt 100, an overlapping area will be formed between two adjacent turns of the corrugated belt 100. At this time, the two turns of the corrugated belt 100 in the overlapping area are respectively equivalent to the "protrusion" and the "concave part", which have a connecting function. After the corrugated belt 100 is spirally wound into a cylindrical structure, it is equivalent to a corrugated pipe, which has a vibration reduction function. The corrugated deformation of the corrugated belt 100 can effectively reduce the vibration experienced by the motorcycle during the ride, so as to protect the internal wiring harness 500.

[0046] In a further embodiment, such as Figure 5 As shown, the interlocking width between two adjacent corrugated strips 100 is at least three-half the wavelength of the corrugated strip 100, that is, the interlocking width between two adjacent corrugated strips 100 is at least 1.5 times the wavelength of the corrugated strip 100.

[0047] This design is intended to increase the stability of the interlocking between two adjacent corrugated belts 100, reduce the risk of disengagement, and avoid excessively wide interlocking sections of the corrugated belts 100 that would result in material waste.

[0048] In a further embodiment, such as Figure 5 and Figure 6 As shown, a steel wire 120 is embedded at the junction of the crests and troughs of the corrugated strip 100, and the steel wire 120 extends along the length of the corrugated strip 100.

[0049] When the corrugated tape 100 is tightly wrapped around the outside of the wire harness 500, the corrugated tape 100 will deform due to the support of the wire harness 500. Since steel wires 120 are embedded at the junction of the crests and troughs of the corrugated tape 100, when the corrugated tape 100 is tightly wrapped around the outside of the wire harness 500, under the constraint of the steel wires 120, the deformation of the corrugated tape 100 due to the support of the wire harness 500 occurs on the inner side of the spiral line where the steel wires 120 are located. At this time, the cross section of the interlocking part of the corrugated tape 100 is deformed into a wedge shape with a wider inner side and a narrower outer side under the support of the wire harness 500. This increases the interlocking stability between two adjacent turns of the corrugated tape 100, prevents the two adjacent turns of the corrugated tape 100 from disengaging, and prevents dust, rainwater, etc. from entering the cylindrical structure formed by the corrugated tape 100 through the gaps.

[0050] It is understandable that the wire harness 500 generally consists of a main section and multiple branch sections. When the corrugated tape 100 spirally winds to the bifurcation point of the wire harness 500, exposed holes inevitably appear at the bifurcation point. This makes it easy for dust, rainwater, etc., to enter the cylindrical structure formed by the corrugated tape 100, which is detrimental to the protection of the wire harness 500. To solve this problem, in a further embodiment, such as Figure 1 , Figure 2 and Figure 7 As shown, a wiring harness protection device for a motorcycle also includes a multi-pass guide sleeve 220 (the multi-pass guide sleeve 220 shown in the attached figure is a three-pass type, and in production, the multi-pass guide sleeve 220 can be designed as an N-pass type according to actual needs, where N≥3), and the multi-pass guide sleeve 220 is fitted at the bifurcation position of the wiring harness 500.

[0051] Before the corrugated tape 100 is spirally wound to the bifurcation point of the wire harness 500, the worker places the multi-port guide sleeve 220 on the bifurcation point of the wire harness 500. After the corrugated tape 100 is spirally wound to the bifurcation point of the wire harness 500, the worker then spirally winds the corrugated tape 100 around the outside of the multi-port guide sleeve 220. At this time, under the action of the multi-port guide sleeve 220, the inner and outer areas of the corrugated tape 100 are isolated, thereby preventing dust, rainwater, etc. from entering the cylindrical structure formed by the corrugated tape 100.

[0052] It should also be noted that, to further improve the sealing performance and prevent dust and rainwater from entering the cylindrical structure formed by the corrugated belt 100, a layer of sealant can be applied to the outside of the multi-port guide sleeve 220 before spirally winding the corrugated belt 100 onto the multi-port guide sleeve 220. Then, the corrugated belt 100 is spirally wound onto the outside of the multi-port guide sleeve 220, at which point the sealant fills the corrugated grooves of the corrugated belt 100, thereby preventing dust and rainwater from entering the cylindrical structure formed by the corrugated belt 100. Furthermore, after the sealant solidifies, it also improves the connection stability between the corrugated belt 100 and the multi-port guide sleeve 220, enhancing the connection reliability between them.

[0053] It is understandable that the outer diameter of the multi-port guide sleeve 220 is larger than the outline diameter of the wire harness 500. Therefore, when the corrugated tape 100 is spirally wound to the junction of the multi-port guide sleeve 220 and the wire harness 500, adjacent turns of the corrugated tape 100 may not reliably fasten together due to their own tilt. To solve this problem, in a further embodiment, such as... Figure 1 , Figure 2 and Figure 7 As shown, a motorcycle wiring harness protection device also includes a double-pass guide sleeve 210, which is slidably sleeved on the outside of the wiring harness 500, and the outer diameter of the multi-pass guide sleeve 220 is adapted to the corresponding outer diameter of the sleeve opening of the multi-pass guide sleeve 220.

[0054] Before winding the corrugated tape 100, the operator first places the double-through guide sleeve 210 on one end of the wire harness 500, and then fixes the end of the corrugated tape 100 away from the belt roller 110 at the corresponding end position of the wire harness 500. Next, the corrugated tape 100 is spirally wound around the outside of the double-through guide sleeve 210. When the outside of the double-through guide sleeve 210 is fully wrapped with corrugated tape 100, the operator moves the double-through guide sleeve 210 a preset distance along the length of the wire harness 500 (this preset distance is less than or equal to the length of the double-through guide sleeve 210). At this time, although the corrugated tape 100 originally wrapped around the outside of the double-through guide sleeve 210 is detached from the double-through guide sleeve 210, due to the adjacent two turns of corrugated tape 100... The snap-fit ​​parts of 0 are already snapped together, so even after the corrugated tape 100 is separated from the double-pass guide sleeve 210, it can still maintain a good snap-fit ​​state. When the double-pass guide sleeve 210 moves to contact the corresponding sleeve opening of the multi-pass guide sleeve 220, the worker first wraps the corrugated tape 100 around the outside of the double-pass guide sleeve 210, and then wraps the corrugated tape 100 around the multi-pass guide sleeve 220. Since the diameter of the double-pass guide sleeve 210 is matched with the diameter of the corresponding sleeve opening of the multi-pass guide sleeve 220, there is no height difference at the contact position, so the corrugated tape 100 can be prevented from tilting itself, thereby ensuring that the two adjacent turns of corrugated tape 100 can be reliably snapped together.

[0055] In a further embodiment, such as Figure 1 , Figure 2 and Figure 7 As shown, both the double-pass guide sleeve 210 and the multi-pass guide sleeve 220 include a male part and a female part. Both the male and female parts are semi-ring structures. Both the male and female parts have an outer arc surface, an inner arc surface, a front end surface, a rear end surface, and a side end surface. The male part and the corresponding female part are snapped together to form a ring. Specifically, a number of snap-fit ​​posts can be provided at intervals on the side end surface of the male part. The snap-fit ​​posts are made of plastic. A number of snap-fit ​​holes are provided at intervals on the side end surface of the female part. The diameter of the snap-fit ​​holes is slightly smaller than the diameter of the snap-fit ​​posts, so that after the snap-fit ​​posts are snapped into the snap-fit ​​holes, the male and female parts are connected together by the friction between the snap-fit ​​posts and the snap-fit ​​holes.

[0056] Before installing the double-pass guide sleeve 210, the male and female parts of the double-pass guide sleeve 210 are separate. During installation, the operator positions the male and female parts on opposite sides of the wire harness 500, and then snaps them together using the engagement holes and engagement posts. This forms a loop, allowing the double-pass guide sleeve 210 to be fitted over the wire harness 500. The installation of the multi-pass guide sleeve 220 follows the same procedure, and will not be described in detail here.

[0057] Understandably, when a corrugated tape 100 is spirally wound to the bifurcation point of the wire harness 500, an obvious approach is to spirally wind the corrugated tape 100 from the main section onto one of the branch sections, and then use other corrugated tapes 100 to wind separately for the other branch sections. However, this approach inevitably results in the corrugated tapes 100 wound on multiple branch sections operating independently, leading to poor overall stability of the corrugated tapes 100 wound on multiple branch sections. To address this issue, in a further embodiment, such as... Figure 1 and Figure 2 As shown, there are multiple corrugated strips 100. When working on the main section of the wire harness 500, the multiple corrugated strips 100 are arranged side by side along their width direction, and adjacent two corrugated strips 100 are interlocked with each other. They are also spirally wound along the length direction of the main section of the wire harness 500. After working from the main section of the wire harness 500 to the bifurcation position of the wire harness 500, the multiple corrugated strips 100 are disengaged to form multiple sets of corrugated strips 100 that match the number of bifurcation segments of the wire harness 500. Each set has at least one corrugated strip 100. The multiple sets of corrugated strips 100 correspond one-to-one with the multiple bifurcation segments of the wire harness 500 and are spirally wound along the length direction of the corresponding bifurcation segment of the wire harness 500.

[0058] Taking the winding of corrugated tape 100 starting from the main section of wire harness 500 as an example, the worker can select multiple corrugated tapes 100, no less than the number of branch sections, so that the multiple corrugated tapes 100 are arranged side by side along their width direction, and that adjacent two corrugated tapes 100 are interlocked with each other. Then, the multiple corrugated tapes 100 are spirally wound along the length direction of the main section of wire harness 500. When the work starts from the main section of wire harness 500 and reaches the bifurcation position of wire harness 500, the worker makes the multiple corrugated tapes 100 uninterlock to form multiple sets of corrugated tapes 100, the same number as the number of branch sections. Then, the multiple sets of corrugated tapes 100 are spirally wound on the corresponding bifurcation section of wire harness 500.

[0059] It should also be noted that when the diameter of a certain bifurcation segment is larger than the diameter of other bifurcation segments, the number of corrugated strips 100 contained in a set of corrugated strips 100 corresponding to that bifurcation segment is greater than or equal to two. This is equivalent to increasing the width of the corrugated strips 100, which is beneficial to improving the spiral winding efficiency of the corrugated strips 100.

[0060] It should also be noted that, in order to ensure the smooth transition of multiple corrugated strips 100 from the main section to the branch section, when distributing multiple sets of corrugated strips 100, the foremost set of corrugated strips 100 should be wrapped around the branch section coaxial with the main section, the other set of corrugated strips 100 adjacent to the foremost set of corrugated strips 100 should be wrapped around the branch section with the smallest distance from the main section, and so on, with the last set of corrugated strips 100 wrapped around the branch section with the largest distance from the main section.

[0061] In a further embodiment, such as Figure 8 and Figure 9 As shown, a wiring harness protection device for a motorcycle also includes a connector 300 for pushing a double-pass guide sleeve 210 to move along its own axis.

[0062] The connector 300 is provided to facilitate the sliding of the double-pass guide sleeve 210 along the length of the wire harness 500 by the operator. Specifically, the connector 300 may include a connecting rod 310 and a connecting retaining ring 330. The connecting retaining ring 330 is located at the end of the double-pass guide sleeve 210 corresponding to the branch section, away from the multi-pass guide sleeve 220. When it is necessary to move the double-pass guide sleeve 210 of the branch section, the operator uses the connecting rod 310 to press against the connecting retaining ring 330 and pushes the double-pass guide sleeve 210 along the length of the wire harness 500 towards the end away from the multi-pass guide sleeve 220. For the double-pass guide sleeve 210 of the main section, a mating hole can be opened on one circumferential side of the double-pass guide sleeve 210, and the connecting rod 310 is inserted into the mating hole to push the double-pass guide sleeve 210 to move.

[0063] In a further embodiment, such as Figures 8-10As shown, a motorcycle wiring harness protection device also includes a grip 400, which is connected to a connector 300 and is used to push the double-pass guide sleeve 210 to move along its own axis via the connector 300.

[0064] When it is necessary to move the double-pass guide sleeve 210, the operator first makes the connecting rod 310 pass vertically through the grip part 400, and then the operator holds the grip part 400 with his hand, so that the grip part 400 moves horizontally away from the multi-pass guide sleeve 220. At this time, the grip part 400 drives the connecting rod 310 to move horizontally in sync.

[0065] In a further embodiment, such as Figures 8-10 As shown, the gripping part 400 is also connected to the belt roller 110 to drive the belt roller 110 to move synchronously. The gripping part 400 includes a handle 410, a screw 420, a first limiting ring 430 and a second limiting ring 440. The handle 410 and the screw 420 are coaxially fixedly connected. The first limiting ring 430 is fixedly connected to one end of the screw 420 near the handle 410. The second limiting ring 440 is threadedly connected to the screw 420.

[0066] In use, the operator first removes the second limiting ring 440 from the screw 420, and then puts the belt roller 110 on the outside of the screw 420. It should be noted that when working on the main section of the wire harness 500, multiple belt rollers 110 can be sleeved side by side on the outside of the screw 420. When working on the branch section of the wire harness, one or more belt rollers 110 can be sleeved on the outside of the screw 420 as needed. Next, the second limiting ring 440 is threaded onto the screw 420, and a preset pressure is maintained between the second limiting ring 440 and the belt roller 110, so that the operator can simultaneously drive multiple belt rollers 110 to move spirally around the wire harness 500 by using the handle 410 and the screw 420.

[0067] In further implementation, such as Figures 10-11 As shown, in order to enable the grip 400 to drive the connecting rod 310 to move horizontally synchronously, a connecting hole 450 is provided on the outer peripheral surface of the grip 410. The diameter of the connecting hole 450 is adapted to the diameter of the connecting rod 310. One end of the connecting rod 310 is provided with a limiting ball head 320. The ball diameter of the limiting ball head 320 is larger than the hole diameter of the connecting hole 450.

[0068] When it is necessary to drive the connecting rod 310 to move horizontally synchronously via the handle 410, the operator can insert the connecting rod 310 into the connecting hole 450 until the limiting ball head 320 abuts against the connecting hole 450. At this time, the lower end of the connecting rod 310 abuts against the connecting retaining ring 330, thereby pushing the double-pass guide sleeve 210 to move horizontally.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.

Claims

1. A wire harness protection device for a motorcycle, characterized by, The utility model relates to a kind of winding device of wire harness, including: Corrugated belt, one end is wound on the belt roller, the other end is spirally wound along the length direction of wire harness, and the mutual buckling between adjacent two turns of corrugated belt is formed to form the circumferential closed cylindrical structure, and then wire harness is enclosed in the cylindrical structure inside; The junction of the crest and the trough of the corrugated belt is embedded with a steel wire, which extends along the length direction of the corrugated belt. When the corrugated belt is tightly wound outside the wire harness, the deformation of the corrugated belt caused by the support of the wire harness occurs on the inside of the spiral line where the steel wire is located under the limiting action of the steel wire. At this time, the cross section of the buckling part of the corrugated belt is deformed into a wedge-shaped appearance with a narrow outside and a wide inside under the support of the wire harness. It also includes a multi-pass guide sleeve and a double-pass guide sleeve. The multi-pass guide sleeve is sleeved on the bifurcation position of the wire harness. After operating to the bifurcation position, the corrugated belt is spirally wound outside the multi-pass guide sleeve. The double-pass guide sleeve is slidably sleeved outside the wire harness. When operating, the corrugated belt is spirally wound outside the double-pass guide sleeve.

Each group has at least one corrugated belt. The multiple groups of corrugated belts correspond to the multiple bifurcation segments of the wire harness one by one, and are spirally wound along the length direction of the corresponding bifurcation segments of the wire harness. It also includes a connecting piece for pushing the double-pass guide sleeve to move along its own axis. The connecting piece includes a connecting rod and a connecting retainer. The connecting retainer is arranged at one end of the double-pass guide sleeve away from the multi-pass guide sleeve corresponding to the branch segment. When it is necessary to move the double-pass guide sleeve of the branch segment, the worker pushes the double-pass guide sleeve to move away from the multi-pass guide sleeve by using the connecting rod against the connecting retainer. For the double-pass guide sleeve of the main stem segment, a butt joint hole is formed on one side of the double-pass guide sleeve in the circumferential direction, and the connecting rod is inserted into the butt joint hole to push the double-pass guide sleeve to move.
