Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and in particular to a wire harness bracket and a plugging method. Background Art

[0002] In current wire harness processing, before the wiring harness is connected to terminals, it is often manually placed on a wire harness rack for storage. This rack, acting as a storage carrier, provides a temporary place for the wire harnesses, allowing them to be arranged regularly before further processing, making them easier to manage. When the wiring harness is subsequently connected to terminals, workers can directly remove the corresponding wire harness from the rack, ensuring the continuity of the processing process. This storage method is simple in structure and easy to operate, meeting the storage needs of the wire harness in the early stages of processing to a certain extent.

[0003] However, this existing storage method has limitations. When the wire harness is too long, placing it on a wire harness bracket reduces the inflection point, causing the harness to extend more vertically, thus occupying a larger height space. This is not conducive to efficient space utilization in storage environments with limited space. Increasing the inflection point of the harness to reduce height space also creates significant resistance when pulling out one end of the harness. Summary of the Invention

[0004] In order to solve the problem of how to reduce the height space occupied by the wire harness and how to reduce the pulling resistance when the inflection point increases, the present invention provides a wire harness bracket and a plug-in method.

[0005] In a first aspect, the present invention provides a wiring harness bracket, the wiring harness bracket comprising a bracket assembly and a support rod assembly; The support rod assembly includes a first support rod, a second support rod and a third support rod, wherein the first support rod, the second support rod and the third support rod are respectively connected to the bracket assembly; the second support rod is located lower than the first support rod; the third support rod is located higher than the second support rod; and there is a distance between the first support rod and the third support rod in the horizontal direction; In which, when the first wiring harness is overlapped on the wiring harness bracket, the first wiring harness is sequentially wrapped around the upper side of the first support rod, the lower side of the second support rod and the upper side of the third support rod; the part where the first wiring harness is overlapped on the second support rod is the part where the pulling force is applied.

[0006] In some embodiments, a distance between the second support rod and the third support rod in the horizontal direction is smaller than a distance between the second support rod and the first support rod in the horizontal direction.

[0007] In some embodiments, in the horizontal direction, the second support rod is located on a side of the third support rod away from the first support rod.

[0008] In some embodiments, the support rod assembly also includes a fourth support rod; the fourth support rod is connected to the bracket assembly; when the first wiring harness is overlapped on the wiring harness bracket, the first wiring harness is wound around the first support rod, the second support rod, the fourth support rod and the third support rod in sequence, and the third support rod and the fourth support rod are located on the same side of the first wiring harness.

[0009] In some embodiments, the fourth support rod is located vertically below the third support rod; the second support rod is connected to the bracket assembly through the fourth support rod; The support rod assembly further includes a connecting rod; the connecting rod is connected between the second support rod and the fourth support rod; and the angle of the connecting rod is adjustable with the fourth support rod as the rotation axis.

[0010] In some embodiments, the angle between the axis of the connecting rod and the horizontal plane is a first angle, and the first angle is 40°~50°.

[0011] In some embodiments, the support rod assembly further includes a fifth support rod and a sixth support rod; the fifth support rod and the sixth support rod are both positioned lower than the first support rod and the third support rod; the fifth support rod and the sixth support rod are both positioned higher than the second support rod; and there is a distance between the fifth support rod and the sixth support rod; Wherein, when the second wire harness is overlapped on the wire harness bracket, the second wire harness is sequentially wound around the upper side of the fifth support rod and the upper side of the sixth support rod; the length of the second wire harness is less than the length of the first wire harness.

[0012] In a second aspect, the present invention provides a wiring harness plugging method, which is applied to a wiring harness bracket described in any one of the above embodiments, and includes: The first wiring harnesses are sequentially wound around the upper side of the first support rod, the lower side of the second support rod and the upper side of the third support rod, and then overlapped on the wiring harness bracket; Pick up at least one of the first wire harnesses and connect it to a first connecting portion on the second support rod; pulling the first overlapping portion along the overlapping route of the first wiring harness until the first wiring harness is separated from the wiring harness bracket; Based on the first wire harness being detached from the wire harness support, a terminal is plugged into the first wire harness.

[0013] In some embodiments, when the first wire harness is overlapped on the wire harness bracket, a first length of the first wire harness wrapped around one end of the first support rod and hanging down is greater than a second length of the first wire harness wrapped around one end of the third support rod and hanging down.

[0014] In some embodiments, pulling the first splicing portion along the splicing route of the first wiring harness until the first wiring harness is separated from the wiring harness support includes: pulling the first overlapping portion along the overlapping route of the first wire harness on the first support rod until the second overlapping portion of the first wire harness overlapped on the first support rod is separated from the first support rod; Based on the second overlapping portion being detached from the first support rod, the first overlapping portion is pulled along the overlapping route of the first wire harness on the third support rod until the third overlapping portion of the first wire harness overlapped on the third support rod is detached from the third support rod.

[0015] In order to solve the problem of how to reduce the height space occupied by the wiring harness and how to reduce the pulling resistance when the inflection point increases, the present invention has the following advantages: By connecting the first, second, and third rods of the rod assembly to the bracket assembly, respectively, with the second rod positioned lower than the first rod and the third rod positioned higher than the second rod, and with a horizontal spacing between the first and third rods, and by sequentially wrapping the first wiring harness around the upper side of the first rod, the lower side of the second rod, and the upper side of the third rod in the overlapped state, the first wiring harness can be overlapped on the wiring harness bracket in an M-shaped manner. By utilizing the height difference between the three rods, the first wiring harness, which originally occupied a large amount of height space due to its excessive length and extended vertically, is changed in its spatial extension direction through a specific bypass overlap path, thereby achieving the purpose of compressing the height space occupied. This ultimately solves the problem that when the wiring harness is too long, simply placing it on the bracket takes up too much height space and is not conducive to storage and access. It achieves the effect of efficiently storing longer wiring harnesses in a limited space, while facilitating the staff to perform storage and access operations quickly and accurately. Because the portion where the wire harness is overlapped on the second support rod is set as the portion where the force is applied when pulling, the force application portion is pulled, and the two ends of the wire harness are pulled out of the corresponding first support rod and third support rod in turn, thereby reducing the problem of large resistance caused by each pulling, and ultimately achieving the effect of reducing the height space and reducing the pulling resistance.

[0020] In the field of wire harness processing, before the wire harness is plugged into the terminal, it is usually necessary to overlap it on the wire harness bracket for storage so that it can be taken during subsequent operations. The currently common wire harness brackets, whether they are composed of a bracket assembly 10 and a support rod assembly 20, or other structural forms, have obvious defects when facing wire harnesses that are too long. Because the existing storage method simply places the overlong wire harness on the wire harness bracket, its placement and space utilization are not reasonably planned. The overlong wire harness naturally extends in the vertical direction, so that the height space it occupies when stored is too large, and in a limited storage environment, space resources cannot be efficiently utilized. At the same time, because the wire harness is too long and is placed arbitrarily, the wire harnesses are easily entangled with each other during the storage and retrieval process, and it is difficult for staff to quickly and accurately locate and take the required wire harnesses, which greatly reduces the storage and retrieval efficiency and affects the overall process of wire harness processing. In response to the above problems, Example 1 discloses a wire harness bracket.

[0021] Example 1: In this example, Figure 1 、 Figure 2 As shown, the wiring harness bracket includes a bracket assembly 10 and a support rod assembly 20, which can provide a basic structure for storing the first wiring harness 30. The support rod assembly 20 includes a first support rod 21, a second support rod 22, and a third support rod 23. The first support rod 21, the second support rod 22, and the third support rod 23 are respectively connected to the bracket assembly 10 to form a stable support structure. The second support rod 22 is located lower than the first support rod 21, and the third support rod 23 is located higher than the second support rod 22. The first support rod 21 and the third support rod 23 are spaced apart in the horizontal direction. Through this position setting, a spatial layout can be provided for a specific overlapping method of the first wiring harness 30. When the first wiring harness 30 is overlapped on the wiring harness bracket, the first wiring harness 30 is sequentially wound around the upper side of the first support rod 21, the lower side of the second support rod 22, and the upper side of the third support rod 23. The portion where the first wiring harness 30 overlaps on the second support rod 22 is the portion where the pulling force is applied. Through such a structure and overlapping steps, the overlapping positions of the first wire harness 30 on the first support rod 21, the second support rod 22, and the third support rod 23 can be limited, and the M-shaped overlapping of the first wire harness 30 can be achieved by utilizing the height difference between the first support rod 21, the second support rod 22, and the third support rod 23, thereby reducing the excessive height space occupied by the first wire harness 30 when it is overlapped on the wire harness bracket. At the same time, the position where the first wire harness 30 is pulled out is limited, and the number of inflection points on the pulling path of the first wire harness 30 is reduced to reduce resistance and facilitate storage and retrieval.

[0022] Furthermore, the horizontal spacing between the second support rod 22 and the third support rod 23 is smaller than the horizontal spacing between the second support rod 22 and the first support rod 21, so that the second support rod 22 can be biased toward the side close to the third support rod 23, thereby making the second support rod 22 close to the position for manual picking. At the same time, the angle at which the first wire harness 30 is overlapped on the first support rod 21 is increased, and the contact area between the first wire harness 30 and the first support rod 21 is reduced to reduce the damping force when the first wire harness 30 is picked up, thereby achieving the effect of convenient storage and retrieval.

[0023] Further, such as Figure 2 As shown, in the horizontal direction, the second support rod 22 is located on the side of the third support rod 23 away from the first support rod 21, which can further make the offset position of the second support rod 22 away from the first support rod 21, and increase the angle at which the wire harness is overlapped on the first support rod 21 as much as possible, so that the direction of force applied when pulling the wire harness can be closer to the direction of movement of the wire harness, thereby achieving the purpose of facilitating pulling; at the same time, reducing the contact area between the first wire harness 30 and the first support rod 21 to reduce the damping force when the first wire harness 30 is picked up, thereby achieving the effect of convenient storage and retrieval.

[0024] Further, such as Figure 1 、 Figure 2As shown, the support rod assembly 20 also includes a fourth support rod 24, which is connected to the bracket assembly 10; when the first wiring harness 30 is overlapped on the wiring harness bracket, the first wiring harness 30 is sequentially wound around the first support rod 21, the second support rod 22, the fourth support rod 24 and the third support rod 23, and the third support rod 23 and the fourth support rod 24 are located on the same side of the first wiring harness 30. By adding the fourth support rod 24, the interference between the part of the first wiring harness 30 wrapped around the second support rod 22 and the end of the first wiring harness 30 wrapped around the third support rod 23 when the first wiring harness 30 is overlapped is avoided, resulting in the wiring harness being entangled, thereby facilitating the storage and retrieval of the wiring harness.

[0025] Further, such as Figure 1 、 Figure 2 As shown, the fourth support rod 24 is located vertically below the third support rod 23, and the second support rod 22 is connected to the bracket assembly 10 through the fourth support rod 24; the support rod assembly 20 also includes a connecting rod 25, which is connected between the second support rod 22 and the fourth support rod 24. The angle of the connecting rod 25 with the fourth support rod 24 as the rotation axis is adjustable. Through this structural setting, the position of the second support rod 22 can be adjusted. When the first wiring harness 30 is overlapped, the second support rod 22 can be adjusted to the side of the fourth support rod 24 close to the first support rod 21 or vertically below the fourth support rod 24 to facilitate the overlap of the first wiring harness 30. When the overlap of the first wiring harness 30 is completed, the second support rod 22 can be adjusted to the side of the fourth support rod 24 away from the first support rod 21 to facilitate access to the terminal for plugging.

[0026] Furthermore, the angle between the axis of the connecting rod 25 and the horizontal plane is a first angle, and the first angle is 40°~50°. By limiting the size of the first angle of the connecting rod 25, it is avoided that the bending angle of the first wiring harness 30 is too large when it passes through the second support rod 22 and the fourth support rod 24 when overlapping, resulting in excessive difficulty in overlapping, and the effect of facilitating the storage and retrieval of the wiring harness can be achieved.

[0027] When the first wiring harness 30 is overlapped on the wiring harness bracket, the length of the end of the first wiring harness 30 hanging from the first support rod 21 can be greater than the length of the first wiring harness 30 hanging from the third support rod 23, so as to make full use of the space under the first support rod 21. At the same time, the height of the part where the wiring harness is pulled and force is applied can be raised, which is more ergonomic.

[0028] In order to facilitate the storage of the first wiring harness 30 hanging down from the first support rod 21, in other embodiments, the wiring harness bracket also includes a storage tube 50. There may be multiple storage tubes 50, and multiple storage tubes 50 are placed under the outermost first support rod 21 so that the hanging first wiring harness 30 can be regularly classified into multiple storage tubes 50.

[0029] Furthermore, the first support rod 21 can be provided in multiple numbers. Figure 2 、 Figure 3While two are shown in the figure, it should be understood that three, four, and so on are also possible. This allows the first wire harness 30 to be overlapped on the upper sides of multiple first support rods 21, utilizing horizontal space. This allows the overlap angle of the first wire harness 30 on the first support rod 21 to be at least 90°, preventing excessive withdrawal resistance caused by a narrow overlap angle of the first wire harness 30. The overlap angle of the first wire harness 30 is defined as the angle between the first wire harness 30 on either side of the first wire harness 30's bend. Consequently, even if the end of the first wire harness 30 hanging from the first support rod 21 is too long, it will not significantly affect the withdrawal resistance.

[0030] Furthermore, among the multiple first support rods 21, the line connecting the first support rod 21 closest to the third support rod 23 and the second support rod 22 is a first reference line, and the angle between the first reference line and the horizontal line is a second angle. The first reference line is tangent to the outer edge contours of the first support rod 21 and the second support rod 22 closest to the third support rod 23, respectively. The second angle is smaller than the first angle, and the magnitude of the second angle is negatively correlated with the hardness of the first wire harness 30. Therefore, when the hardness of the first wire harness 30 is lower, the portion of the first wire harness 30 overlapped on the first support rod 21 is pulled until it loosens, and the first wire harness 30 between the first support rod 21 and the second support rod 22 droops more, making it less likely to interfere with and become entangled with the wire harness wound around the fourth support rod 24. This minimizes the second angle, thereby achieving a greater degree of separation between the portion of the first wire harness 30 between the third support rod 23 and the fourth support rod 24 and the portion of the first wire harness 30 hanging from the third support rod 23. Therefore, the angular position relationship of the plurality of support rods in the support rod assembly 20 is designed according to the hardness of the wire harness, so that the wire harness is not easily interfered with during placement and pulling, and the smoothness is higher.

[0031] Further, such as Figure 1 、 Figure 2 As shown, the support rod assembly 20 also includes a fifth support rod 26 and a sixth support rod 27. The positions of the fifth support rod 26 and the sixth support rod 27 are both lower than the first support rod 21 and the third support rod 23, and the positions of the fifth support rod 26 and the sixth support rod 27 are both higher than the second support rod 22. There is a spacing between the fifth support rod 26 and the sixth support rod 27, which can provide a specific support rod structure and position relationship for the overlap of the second wiring harness 40; when the second wiring harness 40 is overlapped on the wiring harness bracket, the second wiring harness 40 is sequentially wound around the upper side of the fifth support rod 26 and the upper side of the sixth support rod 27, and the length of the second wiring harness 40 is less than the length of the first wiring harness 30. Through such an arrangement, the fifth support rod 26 and the sixth support rod 27 are used to overlap the shorter second wiring harness 40, which can reduce the difficulty of overlap while not taking up too much space, thereby improving space utilization.

[0032] Embodiment 2: In this embodiment, this embodiment discloses a wiring harness plugging method, which is applied to a wiring harness bracket of any one of the above embodiments, such as Figure 4As shown, the wiring harness plugging method includes sequentially winding a plurality of first wiring harnesses 30 around the upper side of the first support rod 21, the lower side of the second support rod 22 and the upper side of the third support rod 23 and then overlapping them on the wiring harness bracket, so as to complete the storage of the wiring harness; picking up at least one first wiring harness 30 and overlapping the first overlapping portion on the second support rod 22, so as to determine the picking position; pulling the first overlapping portion along the overlapping route of the first wiring harness 30 until the first wiring harness 30 is separated from the wiring harness bracket, so as to realize the removal of the wiring harness; based on the first wiring harness 30 being separated from the wiring harness bracket, plugging the terminal on the first wiring harness 30, so as to complete the processing of the wiring harness. Through this method, after several first wire harnesses 30 are overlapped on the wire harness bracket, there is a specific picking position when picking up. Picking up the first wire harness 30 from the first overlapping position can reduce the excessive damping force caused by too many turning points when the first wire harness 30 is overlapped. At the same time, it avoids the situation where several first wire harnesses 30 interfere with each other due to excessive friction with other first wire harnesses 30 when picking up one first wire harness 30, which facilitates quick picking up for plugging in terminals.

[0033] Furthermore, when the first wiring harness 30 is overlapped on the wiring harness bracket, the first length of the first wiring harness 30 hanging down at one end of the first support rod 21 is greater than the second length of the first wiring harness 30 hanging down at one end of the third support rod 23. Through such a setting, it is possible to avoid the length of the first wiring harness 30 hanging down at one end of the third support rod 23 being too long to interfere with the picking up of the first wiring harness 30, and the overlap angle of the first wiring harness 30 at the first support rod 21 can be greater than the overlap angle of the wiring harness at the third support rod 23. In conjunction with a specific picking position, the damping force between the first wiring harness 30 and the support rod assembly 20 is minimized as much as possible, which is convenient for storage and access, fully utilizes the position of the space below the first support rod 21, and further optimizes the spatial arrangement of the wiring harness overlap.

[0034] Furthermore, pulling the first overlapping portion along the overlapping route of the first wire harness 30 until the first wire harness 30 is detached from the wire harness bracket includes: pulling the first overlapping portion along the overlapping route of the first wire harness 30 on the first support rod 21 until the second overlapping portion of the first wire harness 30 overlapped on the first support rod 21 is detached from the first support rod 21; based on the detachment of the second overlapping portion from the first support rod 21, pulling the first overlapping portion along the overlapping route of the first wire harness 30 on the third support rod 23 until the third overlapping portion of the first wire harness 30 overlapped on the third support rod 23 is detached from the third support rod 23. Through such steps, the end of the first wire harness 30 overlapped on the first support rod 21 is pulled first, and then the end of the first wire harness 30 overlapped on the third support rod 23 is pulled. This is because the portion of the first wire harness 30 between the first support rod 21 and the second support rod 22 tends to swing toward the first support rod 21 due to increased slack when being pulled. This can avoid interference with the portion of the first wire harness 30 overlapped on the third support rod 23 and the fourth support rod 24 when the first wire harness 30 is pulled, reduce the risk of the first wire harness 30 being entangled, and ensure that the first wire harness 30 is picked up smoothly.

[0035] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
