Description

Technical Field

[0001] The invention relates to the technical field of wire harness conduit penetration, in particular to a wire harness conduit penetration device. Background Art

[0002] In today's era of rapid technological development and the booming of large-scale mechanical equipment industries such as electronic and electrical products and automobiles, wire harnesses are the "nerves" for transmitting power and signals inside various types of equipment. The precise and efficient assembly of wire harnesses and conduits plays a vital role in ensuring product performance, stability and production cycle. When traditional wire harness conduits are inserted manually or with the assistance of simple tooling, there is a lack of effective cable fixing mechanism, and the cables can only be simply gathered together, making it difficult to achieve accurate positioning and orderly arrangement. This makes it very easy for cables to become entangled and chaotic before they are inserted into the conduit, which not only greatly increases the difficulty of threading the conduit, requiring operators to spend a lot of time to untangle the tangled cables, but also easily leads to threading errors, affecting the subsequent use of the wire harness.

[0003] In addition, there is a lack of effective drag reduction design. When the wire harness passes through the conduit, it is completely forced by manpower. Multiple factors such as the friction of the pipe wall, its own torsional force, and possible internal obstacles are superimposed. Once a jam occurs, forcibly pulling the wire harness can easily cause cable damage. If not handled in time, the cable debris remaining in the conduit may also cause electrical faults such as short circuits, endangering product safety. On the other hand, for some conduits with longer lengths and thinner diameters, traditional conduit threading methods are almost helpless and the threading speed is extremely slow.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0005] In order to solve the problem that when the wire harness conduit is inserted manually or with the aid of simple tooling, there is a lack of an effective cable fixing mechanism, and the cables can only be simply gathered together, which makes it difficult to achieve accurate positioning and orderly arrangement. This makes it very easy for the cables to be entangled and messy before being inserted into the conduit. The present invention provides a wire harness conduit insertion device.

[0006] The present invention provides a wire harness conduit insertion device that adopts the following technical solution:

[0007] A wire harness conduit insertion device comprises a wiring base, a group of movable wire seats are installed on the wiring base, a wire harness conduit is detachably installed inside the wire seat, a hoop plate for supporting the wire harness conduit is symmetrically provided on the inner wall of the wire seat, a slide cylinder for guiding the wire harness is rotatably provided on the inner wall of the hoop plate, a center column is detachably installed inside one end of the wire harness conduit, a group of wiring blocks are equidistantly fixedly connected to the outer wall of the center column, a plurality of connecting blocks are equidistantly distributed on the outer wall of the wiring block along the circumferential direction, and a roller is rotatably installed on the outer wall of the connecting block.

[0008] Preferably, the side walls of the wiring base are symmetrically provided with slide grooves, the bottom of the wire holder is connected with a slider via screws, and both ends of the slider are integrally fixed with a card block adapted to the slide groove.

[0009] Preferably, an opening is formed on the top of the wire holder, and an elastic block is bonded and connected to the inner wall of the opening.

[0010] Preferably, a positioning cavity is provided inside the wire holder to provide a movable space for the wire harness conduit, and a support spring is connected between the hoop plate and the inner wall of the positioning cavity for support.

[0011] Preferably, the hoop plate is configured to be semi-arc-shaped, a support rod is fixed to the inner wall of the hoop plate, and the slide cylinder is rotatably connected to the support rod.

[0012] Preferably, an introduction head is fixed to both ends of the central column, and a group of buckle grooves are equidistantly formed on the outer wall of the introduction head.

[0013] Preferably, a pull rod is threadedly connected to the outer wall of the introduction head on one side, a plurality of wire clamping holes are equidistantly formed on the outer wall of the wiring block along the circumferential direction, and an insulating pad is glued and connected to the inner wall of the wire clamping hole.

[0014] Preferably, a plurality of elastic buckle blocks are equidistantly arranged on one side of the wiring block along the circumferential direction, and a support block is connected between the elastic buckle block and the outer wall of the central column.

[0015] In summary, the present invention includes the following beneficial technical effects:

[0016] This application can achieve orderly arrangement of cables through the coordinated arrangement of the introduction head, wiring block, wire clamp and elastic buckle block, avoiding entanglement and confusion between cables, and laying a good foundation for the subsequent smooth insertion into the conduit. The elastic buckle block is used to position the cables at multiple points to form a multi-point stable clamping effect. Compared with the single-point fixing method, the multi-point positioning can fix the cable from multiple angles and positions, so that it will not easily shift or loosen when inserted into the conduit, greatly enhancing the stability of the cable and ensuring that the conduit insertion operation can be carried out smoothly and continuously;

[0017] When pushing one end of the guide head into the wire harness conduit, the roller fits against the inner wall of the wire harness conduit to assist in sliding, cleverly utilizing the principle that rolling friction is less than sliding friction, greatly reducing the resistance of the entire device moving in the conduit. This makes the process of pushing the wire harness into the conduit easier and more labor-saving, reduces labor intensity, and also speeds up the threading speed and improves production efficiency. This assisting effect is more obvious when facing longer conduits with thinner diameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-5 The present invention is described in further detail.

[0025] The embodiment of the present invention discloses a wire harness conduit insertion device. Figure 1, including a wiring base 1, on which a group of movable wire seats 3 are installed, the side walls of the wiring base 1 are symmetrically provided with slide grooves 2, the bottom of the wire seat 3 is connected with a slider 5 by screws, and both ends of the slider 5 are fixed with a block 6 adapted to the slide groove 2 in an integrated structure. According to the wiring requirements of the wire harness, the slider 5 is pushed to slide outside the slide groove 2, and then the support distance of the two wire seats 3 to the wire harness can be adjusted according to the requirements. In the actual wiring harness arrangement, different equipment and scenes have different requirements for the wiring spacing of the wire harness. The present application can flexibly meet various wiring requirements without the need for additional replacement of the device, and only needs to simply adjust the position of the slider 5. The wire harness conduit 4 is detachably installed inside the wire seat 3, and an opening 8 is opened at the top of the wire seat 3, and an elastic block 9 is glued and connected to the inner wall of the opening 8. The setting of the opening 8 facilitates the disassembly of the wire harness, and the elastic block 9 has a certain elasticity, which has a good buffering effect while limiting.

[0026] like Figure 2-Figure 3 As shown, the inner wall of the wire holder 3 is symmetrically provided with a hoop plate 11 for supporting the wire harness conduit 4, and the inner wall of the hoop plate 11 is rotatably provided with a slide cylinder 13 for guiding the wire harness. A positioning cavity 7 is provided inside the wire holder 3 to provide a space for the wire harness conduit 4 to move, and a support spring 10 for support is connected between the hoop plate 11 and the inner wall of the positioning cavity 7. The support springs 10 and the hoop plates 11 on both sides of the wire holder 3 are fitted to the outer wall of the wire harness 4 to position it, which can effectively prevent the wire harness from falling off from the positioning cavity 7. The hoop plate 11 is set to a semi-arc shape, which fits the outer wall of the wire harness more closely. The inner wall of the hoop plate 11 is fixed with a support rod 12, and the slide cylinder 13 is rotatably connected to the support rod 12. The slide cylinder 13 slides on the outer wall of the support rod 12, which can assist the wire harness to slide, provide additional assistance for the movement of the wire harness during the pipe threading process, further reduce the resistance of the wire harness during movement, make the pipe threading process smoother, reduce the occurrence of wire harness jamming and obstruction, and ensure that the threading work can be completed efficiently and smoothly.

[0027] like Figure 4-Figure 5 As shown, a central column 14 is detachably installed inside one end of the harness conduit 4, and an introduction head 16 is fixed at both ends of the central column 14. A group of buckle grooves 18 are equidistantly opened on the outer wall of the introduction head 16. Preliminary buckling of one end of multiple cables in the buckle groove 18 can achieve orderly arrangement of the cables, avoid entanglement and confusion between the cables, and lay a good foundation for subsequent smooth insertion into the conduit. A pull rod 15 is threadedly connected to the outer wall of the introduction head 16 on one side, and a pull rod 15 of a suitable length can be installed according to the size of the harness conduit 4 for use.

[0028] In the present application, a group of wiring blocks 17 are fixedly connected to the outer wall of the center column 14 at equal intervals, and a number of connecting blocks 19 are distributed equidistantly along the circumferential direction on the outer wall of the wiring block 17, and rollers 20 are rotatably mounted on the outer wall of the connecting block 19. When one end of the introduction head 16 is pushed into the wire harness conduit 4, the rollers 20 fit the inner wall of the wire harness conduit 4 to assist in sliding, which cleverly utilizes the principle that rolling friction is less than sliding friction, greatly reducing the resistance of the entire device to move in the conduit, making the process of pushing the wire harness into the conduit easier and more labor-saving. The cooperation of the introduction head 16 and the rollers 20 provides smooth guidance for the wire harness to enter the conduit, and they can ensure that the wire harness enters the conduit smoothly in the correct direction.

[0029] In the present application, the outer wall of the wiring block 17 is provided with a number of wire clamping holes 21 at equal intervals along the circumference, and the inner wall of the wire clamping hole 21 is attached with an insulating pad 24, and the setting of the insulating pad 24 effectively improves the overall insulation performance. During the insertion and subsequent use of the cable, good insulation is very important, which can prevent electrical problems such as leakage and short circuit between cables and between cables and external structures, and ensure the electrical safety of the entire wiring harness system. One side of the wiring block 17 is provided with a number of elastic buckle blocks 23 at equal intervals along the circumference, and a support block 22 is connected between the elastic buckle block 23 and the outer wall of the center column 14. The elastic buckle block 23 performs multi-point positioning on the cable, forming a multi-point stable clamping effect, and can fix the cable from multiple angles and positions, so that it will not easily shift or loosen when it is inserted into the conduit, greatly enhancing the stability of the cable, ensuring that the pipe threading operation can be carried out smoothly and continuously, reducing the situation where the cable needs to be readjusted due to loose cables, and improving the one-time success rate of the pipe threading operation.

[0030] The implementation principle of a wire harness conduit insertion device according to an embodiment of the present invention is as follows:

[0031] When in use, one end of the multiple cables is initially buckled in the buckle groove 18, and the cables are evenly distributed in the clamping holes 21 inside the wiring block 17. The insulating pad 24 is set to improve the insulation performance. The elastic buckle block 23 is also used to perform multi-point positioning on the cables to ensure the clamping effect of the cables, further ensure the stability of the cables when they are inserted into the conduit, and avoid loosening. After the ends of the multiple cables are fixed, one end of the introduction head 16 is then pushed into the wire harness conduit 4. At this time, the roller 20 fits the inner wall of the wire harness conduit 4 to assist in sliding, which greatly reduces the resistance to movement, and then drives the wire harness into the interior of the wire harness conduit 4. The pull rod 15 of the corresponding length is installed to push the center column 14 to extend into the wire harness conduit 4 for conduit insertion;

[0032] At this time, the support springs 10 and hoop plates 11 on both sides of the wire holder 3 are used to fit the outer wall of the wire harness to position it, preventing the wire harness from falling off the positioning cavity 7, and the slide cylinder 13 slides on the outer wall of the support rod 12 to assist the wire harness in sliding, further ensuring the smoothness of threading and preventing the wire harness from loosening. The slider 5 can also be pushed to slide outside the slide groove 2 according to the wiring requirements of the wire harness, and the support distance of the two wire holders 3 to the wire harness can be adjusted according to the needs.
