Description

Technical Field

[0001] This utility model relates to the field of wire harnesses, specifically a wire harness guiding and protection device. Background Technology

[0002] Automotive wiring harnesses are key components inside a car used to transmit electrical energy and signals. They consist of multiple insulated wires, cables, and related connectors and protective components. Like the car's "neural network," they connect the car's engine, chassis, body, and various electronic devices, and are responsible for power supply and signal transmission, ensuring that all car systems can work in a coordinated manner.

[0003] Before installing and fixing automotive wiring harnesses into the vehicle body, in order to prevent the wiring harnesses from being damaged by external factors such as vibration and friction during vehicle operation and to ensure their service life and transmission performance, manufacturers usually use corrugated tubing to cover the outside of the wiring harnesses. Corrugated tubing has good flexibility, wear resistance and corrosion resistance, which can provide effective physical protection for the wiring harnesses and reduce the adverse effects of the external environment on the wiring harnesses.

[0004] When installing corrugated tubing over a wire harness, the operator typically inserts the end of the wire harness into the tubing first, then gradually pushes it into the tubing. However, because the inner wall of the corrugated tubing has corrugated grooves, and the wire harness itself is relatively flexible, the end of the wire harness easily touches these grooves during insertion. These grooves then obstruct the wire harness's insertion, requiring the operator to expend more effort and time to adjust the position and angle of the wire harness, severely impacting the speed and efficiency of installing the corrugated tubing. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a wire harness guiding and protection device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire harness guiding and protection device, comprising a first guide shell and a second guide shell, wherein the top of the first guide shell is movably connected to the second guide shell, the first guide shell and the second guide shell are combined to form a guiding assembly, a guide head is fixed at one end of the first guide shell, a pull rope is connected to the outer wall of the guide head, a fixing assembly is installed on the outer wall of the second guide shell, the fixing assembly includes a rotating plate, a connecting column is fixed to the inner wall of the rotating plate, a fixing strip is connected to the end of the connecting column, and the fixing strip is disposed inside the second guide shell, an insertion hole is opened inside the first guide shell, and a pressing plate is provided on the inner wall of both the first guide shell and the second guide shell.

[0007] By adopting the above technical solution, the problem of the grooves on the inner wall of the corrugated pipe hindering the movement of the wire harness during insertion into the corrugated pipe is solved. Before inserting the wire harness into the corrugated pipe, the end of the wire harness is first installed inside the first guide shell. Then, the second guide shell is flipped over and covers the first guide shell. The rotating plate is rotated so that the fixing component fixes the first and second guide shells. The extrusion plates inside the first and second guide shells extrude and fix the wire harness. Finally, the guide component with the fixed end of the wire harness is pulled from one end of the corrugated pipe to the other end by a pull rope. The guide head at the end of the guide component is set to be hemispherical, which reduces the obstruction of the grooves on the inner wall of the corrugated pipe to the guide component.

[0008] The present invention is further configured such that the guide head is hemispherical, and the diameter of the guide head is smaller than the inner wall diameter of the bellows.

[0009] Preferably, when the guide assembly moves inside the bellows, the guide head guides the movement of the guide assembly, thereby reducing the obstruction of the guide assembly by the grooves on the inner wall of the bellows.

[0010] The present invention is further configured such that a handball is fixed to the end of the pull rope, and the handball is hollow inside.

[0011] Preferably, after the wiring harness is installed inside the guide assembly, personnel can pull and move the guide assembly using a hand ball and a pull rope.

[0012] The present invention is further configured such that the diameter of the rotating plate is equal to the outer wall diameter of the second guide shell, and the rotating plate is configured as a semi-circle.

[0013] Preferably, when the fixing strip rotates to the end of the inner wall of the socket, the rotating plate wraps around the first guide shell, and the spring force causes the first guide shell and the second guide shell to tend to flip away from each other, while also causing the rotating plate to fit tightly against the outer wall of the first guide shell. The first guide shell is fixed to the second guide shell by the rotating plate and the fixing strip.

[0014] The present invention is further configured such that a wire harness is provided inside the first guide shell, and the end of the wire harness is in contact with the inner wall of the guide head.

[0015] Preferably, the guide assembly wraps and fixes the end of the wire harness so that the guide assembly can carry the wire harness along with it when it moves inside the bellows.

[0016] The present invention is further configured such that the inner wall diameter of the extrusion plate is smaller than the inner wall diameter of the first guide shell, and a spring is installed at one end of the extrusion plate, and the end of the spring is connected and fixed to the inner wall of the first guide shell.

[0017] Preferably, when the first guide shell and the second guide shell are flipped and fixed, the extrusion plates inside them extrude and fix the wire harness.

[0018] The present invention is further provided that the inner wall of the extrusion plate is provided with multiple sets of anti-slip strips, and the anti-slip strips are made of rubber.

[0019] Preferably, the rubber anti-slip strip on the inner wall of the extrusion plate can increase the friction between the extrusion plate and the outer wall of the wire harness, thereby increasing the fixing effect of the extrusion plate on the wire harness.

[0020] The present invention is further configured such that the diameter of the handball is smaller than the inner wall diameter of the corrugated pipe, and the pull rope is made of elastic steel wire with a diameter of 3mm.

[0021] Preferably, the elastic steel wire rope has a certain degree of toughness, allowing personnel to transmit the rope into the corrugated pipe, so that the hand ball at the end of the rope can move inside the corrugated pipe.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of the grooves on the inner wall of the corrugated pipe hindering the movement of the wire harness during insertion into the corrugated pipe by setting a first guide shell, a second guide shell, a rotating plate, a fixing strip, a pressing plate, a guide head, and a pull rope. Before inserting the wire harness into the corrugated pipe, the end of the wire harness is first installed inside the first guide shell. Then, the second guide shell is flipped over to cover the first guide shell. The rotating plate is rotated so that the fixing component fixes the first and second guide shells. The pressing plate inside the first and second guide shells presses and fixes the wire harness. Finally, the guide component with the fixed end of the wire harness is pulled from one end of the corrugated pipe to the other end by the pull rope. The guide head at the end of the guide component is set as a hemispherical shape, which reduces the obstruction of the grooves on the inner wall of the corrugated pipe to the guide component.

[0024] 2. This utility model, by setting a guide head, a fixing ring, a movable buckle, and a protective ring, allows personnel to replace the pull rope according to the length of the corrugated pipe when installing a long wire harness inside the corrugated pipe.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] First embodiment:

[0036] Please see Figure 1 — Figure 5The system includes a first guide shell 1 and a second guide shell 2. The top of the first guide shell 1 is movably connected to the second guide shell 2. The first guide shell 1 and the second guide shell 2 are combined to form a guide assembly. A guide head 101 is fixed to one end of the first guide shell 1. A pull rope 5 is connected to the outer wall of the guide head 101. A fixing assembly is installed on the outer wall of the second guide shell 2. The fixing assembly includes a rotating plate 3. A connecting post 301 is fixed to the inner wall of the rotating plate 3. A fixing strip 302 is connected to the end of the connecting post 301 and is located inside the second guide shell 2. An insertion hole 102 is provided inside the first guide shell 1. Both the inner walls of the first guide shell 1 and the second guide shell 2 are provided with extrusion plates 6, which solves the problem of wire harness insertion wave To address the issue of the grooves on the inner wall of the corrugated tube hindering the movement of the wire harness during the process of inserting the wire harness 4 into the corrugated tube, the end of the wire harness 4 is first installed inside the first guide shell 1 before inserting the wire harness 4 into the corrugated tube. Then, the second guide shell 2 is flipped over to cover the first guide shell 1. The rotating plate 3 is rotated so that the fixing component fixes the first guide shell 1 and the second guide shell 2. The extrusion plate 6 inside the first guide shell 1 and the second guide shell 2 extrudes and fixes the wire harness 4. Finally, the guide component with the end of the wire harness 4 fixed is pulled from one end of the corrugated tube to the other end of the corrugated tube by the pull rope 5. The guide head 101 at the end of the guide component is set to be hemispherical, which reduces the obstruction of the grooves on the inner wall of the corrugated tube to the guide component.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The guide head 101 is set to be hemispherical, and the diameter of the guide head 101 is smaller than the inner wall diameter of the bellows. When the guide assembly moves inside the bellows, the guide head 101 guides the movement of the guide assembly, thereby reducing the obstruction of the groove on the inner wall of the bellows to the guide assembly.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The end of the pull rope 5 is fixed with a hand ball 501, and the hand ball 501 is hollow inside. After the wire harness 4 is installed inside the guide assembly, the personnel can pull and move the guide assembly through the hand ball 501 and the pull rope 5.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The diameter of the rotating plate 3 is equal to the outer wall diameter of the second guide shell 2. The rotating plate 3 is set as a semi-circle. When the fixing strip 302 rotates to the end of the inner wall of the insertion hole 102, the rotating plate 3 wraps around the first guide shell 1. The elastic force of the spring 602 makes the first guide shell 1 and the second guide shell 2 tend to flip away. At the same time, the rotating plate 3 is tightly attached to the outer wall of the first guide shell 1. The first guide shell 1 is fixed to the second guide shell 2 by the rotating plate 3 and the fixing strip 302.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The first guide shell 1 is provided with a wire harness 4 inside, and the end of the wire harness 4 is in contact with the inner wall of the guide head 101. The guide assembly wraps and fixes the end of the wire harness 4 so that when the guide assembly moves inside the bellows, the guide assembly can carry the wire harness 4 along with it.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The inner diameter of the extrusion plate 6 is smaller than the inner diameter of the first guide shell 1. A spring 602 is installed at one end of the extrusion plate 6, and the end of the spring 602 is connected and fixed on the inner wall of the first guide shell 1. When the first guide shell 1 and the second guide shell 2 are flipped and fixed, the extrusion plate 6 inside them extrudes and fixes the wire harness 4.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The inner wall of the extrusion plate 6 is provided with multiple sets of anti-slip strips 601, and the anti-slip strips 601 are made of rubber. The rubber anti-slip strips 601 on the inner wall of the extrusion plate 6 can increase the friction between the extrusion plate 6 and the outer wall of the wire harness 4, thereby increasing the fixing effect of the extrusion plate 6 on the wire harness 4.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The diameter of the handball 501 is smaller than the inner wall diameter of the corrugated pipe. The pull rope 5 is made of elastic steel wire and has a diameter of 3mm. The elastic steel wire pull rope 5 has a certain toughness, which allows the personnel to transmit the pull rope 5 into the corrugated pipe, so that the handball 501 at the end of the pull rope 5 can move inside the corrugated pipe.

[0044] Second embodiment:

[0045] Please see Figure 6 A fixing ring 103 is fixed to the outer wall of the guide head 101, and a movable buckle 502 is installed at the end of the pull rope 5. Personnel can connect the pull rope 5 to the fixing ring 103 through the movable buckle 502. When the wire harness 4 needs to be installed into a long corrugated pipe, personnel can replace the pull rope 5 connected to the end of the guide head 101 according to the length of the corrugated pipe, so that the length of the pull rope 5 is greater than the length of the corrugated pipe. A protective ring 7 is installed at one end of the first guide shell 1 and the second guide shell 2. The protective ring 7 is made of rubber. After the wire harness 4 is installed inside the guide assembly, personnel can wrap a plastic bag around the outer wall of the protective ring 7, so that the protective ring 7 is wrapped around the outer wall of the wire harness 4. The protective ring 7 wrapped with a plastic bag makes the fixation between the first guide shell 1 and the second guide shell 2 more stable.

[0046] In practical operation, before the corrugated tube is fitted over the wire harness 4, the hand ball 501 is first inserted into the corrugated tube. The operator pushes the elastic steel wire pull rope 5 into the corrugated tube, causing the hand ball 501 at the end of the pull rope 5 to move from one end of the corrugated tube to the other. Then, the second guide shell 2 is flipped open to one side of the first guide shell 1, and the ends of the multiple sets of wire harnesses 4 that need to be inserted into the corrugated tube are placed inside the first guide shell 1, with the ends of the wire harnesses 4 contacting the inner wall of the guide head 101. Then... The second guide shell 2 flips over and covers the top of the first guide shell 1. The operator holds the first guide shell 1 and the second guide shell 2 with their hands to make the first guide shell 1 and the second guide shell 2 fit tightly together. Then, the rotating plate 3 on the top of the second guide shell 2 is rotated so that most of the rotating plate 3 rotates to the outer wall of the first guide shell 1. The rotating plate 3 drives the fixing strip 302 through the connecting column 301 to be inserted into the first guide shell 1 through the insertion hole 102 at the end of the first guide shell 1, so that the fixing assembly fixes the first guide shell 1 and the second guide shell 2.

[0047] When the second guide shell 2 is tightly fitted with the first guide shell 1, the extrusion plates 6 inside the first guide shell 1 and the second guide shell 2 extrude and fix multiple sets of wire harnesses 4. At the same time, the wire harnesses 4 also exert a reaction force on the extrusion plates 6, causing the extrusion plates 6 to compress the compression spring 602. The spring 602, which is in a compressed state, extrudes and fixes the wire harnesses 4 through the extrusion plates 6. Then, the operator pulls the first guide shell 1 through the hand ball 501, causing the guide assembly to move the wire harnesses 4 from one end of the bellows to the other end. After the wire harnesses 4 are inserted into the bellows, the operator rotates the rotating plate 3 back to the top of the second guide shell 2 and flips the second guide shell 2 open, thereby removing the wire harnesses 4 from the guide assembly.

[0048] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
