Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for electrical wiring of rail transit vehicles, and in particular to a wire harness straightening mechanism, a wire straightening assembly, and a wire straightener. Background Technology

[0002] In the wiring process of the underframe cable trays of rail vehicles, the work of organizing, straightening and bundling the wire harnesses is particularly critical.

[0003] In the initial stage, multiple wire harnesses are laid according to their respective start and end points. Then, meticulous organization and straightening are carried out strictly according to the order of branch points and the length of the wire harnesses within the cable trays. During this process, it is crucial to ensure that cables and harnesses do not cross or experience stress, eliminating any potential malfunctions. Particularly noteworthy is that during the organization and straightening phase, the wire harnesses that branch out first must be properly placed on the outermost layer of the overall harness, i.e., at the very edge, to ensure the neatness and clarity of the wiring. After organization and straightening, the wire harnesses are securely fixed to the crossbeams of the underframe cable trays at specific intervals, ensuring the harnesses remain stable and orderly during vehicle operation, laying a solid foundation for the stable operation of the rail vehicle's electrical system.

[0004] In the wiring work of rail vehicle underframes, there are many complex wire harnesses involved, with varying cable diameters, the thinnest of which is only 1.5mm. 2 This presents a significant challenge to cabling work. Especially during the bundling stage, the tricky problem of wire harnesses crossing and becoming stressed is highly likely. When bundling the entire wire harness from below, visibility is easily obstructed, making it difficult for operators to clearly see the specific situation visually. They can only rely on their own operational experience and their impression of the bundling before straightening to judge the bundling effect. As a result, it often leads to the discovery of severe wire harness crossing only after bundling is completed, necessitating rework and redoing the straightening, tidying, and bundling processes. This process not only consumes a lot of time and labor costs but also negatively impacts the final quality of the cabling, making it difficult to guarantee product yield.

[0005] Therefore, in view of the above problems, it is necessary for this utility model to provide a wire harness straightening mechanism, wire straightening component, and wire straightener that can achieve time-saving, labor-saving, and precise assistance in straightening and organizing wire harnesses. Utility Model Content

[0006] This invention addresses the problem of low quality and efficiency in wire harness organization and straightening during wiring.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The wire harness straightening mechanism disclosed in this utility model is used to straighten multi-branch wire harnesses, comprising:

[0009] The mother-daughter assembly comprises a mother sleeve and a daughter sleeve that can fit against one side of the mother sleeve. One end of the daughter sleeve is rotatably connected to the mother sleeve via a connector, and a fitting path is formed at the fitting position of the daughter sleeve and the mother sleeve. Multiple concave structural cavities are formed on both the daughter sleeve and the mother sleeve along the fitting path. The concave structural cavities on the daughter sleeve correspond to the concave structural cavities on the mother sleeve. The concave structural cavities on the daughter sleeve and the concave structural cavities on the mother sleeve mutually enclose each other to form a closed annular straightening channel.

[0010] Furthermore, the concave cavity is constructed as an arc-shaped structure.

[0011] Furthermore, the female sleeve includes a free end and a connecting end, and the width A of the female sleeve at the connecting end is the overall width of the female-child assembly.

[0012] Furthermore, a fitting groove is formed on one side of the female sleeve to accommodate the female sleeve.

[0013] Furthermore, the female sleeve body has a protruding first connecting sleeve at the fitting groove end of the connecting end, and a slot is provided in the middle of the first connecting sleeve. The female sleeve body has a second connecting sleeve at its end, and the second connecting sleeve is inserted into the slot. The connecting member passes through the first connecting sleeve and the second connecting sleeve.

[0014] Furthermore, the connector is a screw or a pin.

[0015] The wire straightening assembly disclosed in this utility model includes at least two wire harness straightening mechanisms as described above, which are connected end to end in sequence.

[0016] Furthermore, the parent-child assembly comprises two parts, and the two parent-child assemblies are connected end-to-end by a connecting structure to form a closed ring structure.

[0017] Furthermore, the connecting structure includes a dovetail groove and a dovetail boss, the dovetail boss being able to engage or disengage from the dovetail groove.

[0018] Furthermore, the dovetail boss includes a first protrusion and a second protrusion;

[0019] The first protrusion is formed at one end of the female sleeve body, and the dovetail groove is formed at the other end. The second protrusion is formed at one end of the female sleeve body.

[0020] Furthermore, the mother sleeve is arc-shaped or concave, and the daughter sleeve is configured to conform to the shape.

[0021] The cable straightener disclosed in this utility model has multiple cable straightening components as described above, and the multiple cable straightening components are arranged in a nested manner.

[0022] Furthermore, a snap-fit ​​structure is connected between the wire harness straightening mechanisms of two adjacent wire straightening assemblies to position the relative positions of the two adjacent wire straightening assemblies.

[0023] Furthermore, the snap-fit ​​structure includes a snap-fit ​​block and a snap-fit ​​slot, wherein the snap-fit ​​block can engage or disengage with the snap-fit ​​slot.

[0024] In the above technical solution, the wire harness straightening mechanism forms a mother-daughter assembly through the sub-sleeve and the mother sleeve, and uses the concave structural cavity on the fitting path to form multiple straightening channels to shape and fix the wire harness position, ensuring that the wire harness is not crossed and is aesthetically pleasing after forming, thereby improving the efficiency and quality of the overall wiring.

[0025] Since the wire harness straightening mechanism is assembled into a straightening component, the modular design allows for quick replacement and adjustment according to the specific requirements of different rail vehicles, achieving a reasonable layout of branch point wire harnesses and reducing wire harness crossings. Therefore, the modular design facilitates flexible adjustments based on different wire harness specifications and wiring requirements.

[0026] Because the double-layer straightening components are combined to form a cable straightener, not only does the number of cables straightened increase, but the application scenarios also increase, the layering effect is better, the finished quality is improved, and the crossover of the cable harness is further reduced.

[0027] This wire harness straightening mechanism, straightening component, and wire straightener achieves time-saving, labor-saving, and precise assistance in straightening and organizing wire harnesses. It has become a key measure to improve the production efficiency of rail vehicles and ensure product quality, and has immeasurable practical significance. Attached Figure Description

[0046] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0047] A utility model discloses a multi-branch wire harness straightening mechanism for straightening multi-branch wire harnesses during wiring operations on the underframe of rail vehicles;

[0048] Figure 1 The front view of the wire harness straightening mechanism is shown;

[0049] Figure 2 A schematic diagram of the straightening mechanism in its open state is shown;

[0050] The wire harness straightening mechanism includes: a mother-daughter assembly 10, which includes a female sleeve 1 and a daughter sleeve 2;

[0051] The sub-sleeve 2 can fit against one side of the mother sleeve 1. One end of the sub-sleeve 2 is rotatably connected to the mother sleeve 1 through a connector, and the other end is a free end. The fitting position of the sub-sleeve 2 and the mother sleeve 1 forms a fitting path 20. The sub-sleeve 2 and the mother sleeve 1 are located at the fitting path 20 and have multiple corresponding concave structural cavities 103 and 202 along the fitting path 20. The concave structural cavity 202 on the sub-sleeve 2 and the concave structural cavity 101 on the mother sleeve 1 enclose each other to form a closed annular straightening channel 30.

[0052] Specifically, in this structure, one end of the sub-sleeve 2 is rotatably connected to the female sleeve 1 via a connector, thereby allowing the sub-sleeve 2 to fit snugly against one side of the female sleeve 1 and be in use; or

[0053] An angular displacement occurs between the sub-sleeve 2 and the mother sleeve 1, and the free end is in the open state;

[0054] A fitting path 20 is formed at the fitting position of the sub-sleeve 2 and the mother sleeve 1. The sub-sleeve 2 has a series of concave structural cavities 202 along the fitting path 20, and the mother sleeve 1 has a series of concave structural cavities 103 along the fitting path 20. The two concave structural cavities on the sub-sleeve 2 and the mother sleeve 1 are symmetrically arranged. When the sub-sleeve 2 and the mother sleeve 1 are fitted together, the continuous concave structural cavities 103 form a separate closed annular chamber, thereby forming a series of straightening channels 30. The ends of the sub-sleeve 2 and the mother sleeve 1 away from the connector are free ends. These free ends can be opened freely without external force constraints, quickly releasing the wire harness in the straightening channel 30, which is convenient and fast.

[0055] Figure 5 A schematic diagram showing the wire harness straightening mechanism in use is shown:

[0056] In use, when the sub-sleeve 2 is fitted onto one side of the mother sleeve 1, the two concave structural cavities 103 and 202 form a closed annular threading channel 30, such as... Figure 5 As shown, it is used to accommodate cable 5. When straightening cable 5, the sub-sleeve 2 is attached to one side of the mother sleeve 1. Cable 5 is placed in its respective straightening channel 30 and moves in the direction of cable bundle laying to complete the straightening operation. When using it, you can hold the free end and hold the sub-sleeve 2 and mother sleeve 1 at the free end to prevent the free end from opening freely without external force constraint.

[0057] When the sub-sleeve 2 rotates and forms an angular displacement with the mother sleeve 1, the two concave structural cavities 103 and 202 separate, the cable-strapping channel 30 opens, and the cable 5 is released;

[0058] Figure 3 The front view of the mother sleeve is shown;

[0059] Preferably, a fitting groove 105 is formed on one side of the female sleeve 1, and the female sleeve 1 accommodates the female sleeve 2 through the fitting groove 105.

[0060] Specifically, in this structure, the female sleeve 1 is fitted with the female sleeve 2 through the fitting groove 105. When the female sleeve 2 is fitted to one side of the female sleeve 1, as... Figure 1 As shown, the two sides of the mother-daughter assembly 10 form smooth sidewalls to avoid protrusions or depressions that could easily snag the cable. The bonding path 20 is located in the middle of the mother-daughter assembly 10 and extends along the length direction. The concave structural cavity 103 is formed on the sidewall of the bonding groove 105. Multiple concave structural cavities 103 are arranged in a serrated pattern and spaced apart. Similarly, concave structural cavities 202 are arranged in a serrated pattern and spaced apart on the outer wall of the daughter sleeve 2.

[0061] See Figure 1 As shown:

[0062] Preferably, the concave structural cavities 103 and 202 are both half-circular arc structures. Specifically, the number of concave structural cavities 202 and 103 on the outer wall of the sub-sleeve 2 and the inner wall of the mother sleeve 1 are equal and their positions correspond. When the sub-sleeve 2 is attached to one side of the mother sleeve 1, the two concave structural cavities form a circular thread-strapping channel 30 to ensure smooth thread-strapping.

[0063] See Figure 1 , 3 As shown:

[0064] Preferably, the female sleeve 1 includes a free end and a connecting end, and the width A of the female sleeve 1 at the connecting end is the overall width of the female-child assembly 10.

[0065] Specifically, in this structure, in order to make the parent-child assembly 10 compact, lightweight, small, and easy to carry, the width A of the mother sleeve 1 is set as the overall width of the parent-child assembly 10. The child sleeve 2 should not protrude outward from the outside of the mother sleeve 1. The structural characteristics of the child sleeve 2 and the mother sleeve 1 are rationally utilized. While ensuring the structural integrity of the multiple wire straightening channels 30, the wall thickness of the child sleeve 2 and the mother sleeve 1 is reduced as much as possible, thereby controlling the overall width of the parent-child assembly 10 and realizing the lightweight design of this multi-branch wire harness straightening mechanism.

[0066] See Figure 3 , 4 As shown:

[0067] Preferably, the female sleeve 1 has a protruding first connecting sleeve 104 formed at the end of the fitting groove 105 at the connecting end, and a slot is provided in the middle of the first connecting sleeve 104. The female sleeve 2 has a second connecting sleeve 203 formed at the end, and the second connecting sleeve 203 is inserted into the slot. The connector passes through the first connecting sleeve 104 and the second connecting sleeve 203.

[0068] Specifically, in this structure, the width of the female sleeve 1 at the connecting end is the overall width, and a first connecting sleeve 104 is provided at the end of the fitting groove 105, which effectively reduces the width of the connection position between the female sleeve 1 and the female sleeve 2. During assembly, the female sleeve 2 is inserted into the slot of the first connecting sleeve 104 through the second connecting sleeve 203. The connector passes through the shaft hole of the first connecting sleeve 104 and the second connecting sleeve 203, so that the female sleeve 2 can be rotatably connected to one side of the female sleeve 1.

[0069] In a preferred embodiment, the connector is a slotted or hexagonal screw 3. To avoid increasing the thickness of the female-female assembly 10, countersunk holes are provided at both ends of the first connecting sleeve 104 to accommodate the nut 4 and the screw head. The cross-sectional shape of one countersunk hole can be set to a hexagonal structure to fit the shape of the hexagonal nut 4, which can reduce the use of an auxiliary wrench. The countersunk hole setting can help ensure the flatness of the surface of the female sleeve 1. In this embodiment, one of the countersunk holes can also be changed to a threaded hole, and the screw 3 can be directly threaded to the female sleeve 1, reducing the use of nuts.

[0070] In another preferred embodiment, the connecting member is a pin, which connects the sub-sleeve 2 and the female sleeve 1 through a retaining ring;

[0071] Of course, the connector can also be other structures in the prior art, such as a snap-fit ​​structure, which can enable angular displacement between the sub-sleeve 2 and the mother sleeve 1, and can close the sub-sleeve 2 and the mother sleeve 1 and keep the cable-strapping channel 30 intact. This embodiment only takes the screw 3 and nut 4 in conjunction with the first connecting sleeve 104 and the second connecting sleeve 203 as an example.

[0072] This utility model discloses a wire straightening assembly;

[0073] Figure 6 The main view of the straightening component is shown;

[0074] The cable straightening assembly includes at least two of the aforementioned cable straightening mechanisms, with adjacent cable straightening mechanisms connected end to end in sequence, thereby expanding the number of straightening channels 30 and meeting the needs of different usage scenarios;

[0075] Preferably, the parent-child assembly 10 includes two parts, and the two parent-child assemblies 10 are connected end to end by a connecting structure to form a closed ring structure;

[0076] Specifically, the cable straightening assembly includes two cable straightening mechanisms. Of course, depending on the actual usage requirements, there can be more than two. Two adjacent cable straightening mechanisms can be detachably and fixedly connected through a connecting structure to increase the number of straightening channels 30. In use, multiple cable harnesses are straightened simultaneously by two sets of cable straightening mechanisms, thereby expanding the number of cable harnesses that a single cable straightening mechanism can straighten.

[0077] See Figure 3 , 4 As shown in Figure 6:

[0078] Preferably, the connection structure includes a dovetail groove 102 and a dovetail boss. The dovetail boss can engage or disengage from the dovetail groove 102. In this structure, the dovetail boss and the dovetail groove 102 cooperate to connect two adjacent female-female assemblies 10, which is convenient for assembly.

[0079] See Figure 1 As shown:

[0080] Preferably, the dovetail boss includes a first protrusion 101 and a second protrusion 201;

[0081] The female sleeve 1 has a first protrusion 101 at one end and a dovetail groove 102 at the other end. The female sleeve 2 has a second protrusion 201 at one end. Specifically, the free ends of the female sleeve 1 and the female sleeve 2 respectively form the first protrusion 101 and the second protrusion 201.

[0082] In use, when the sub-sleeve 2 is attached to the mother sleeve 1, the first protrusion 101 and the second protrusion 201 close to form a dovetail protrusion. The dovetail protrusion and the dovetail groove 102 are adapted to each other, so that the dovetail protrusion and the dovetail groove 102 of the adjacent mother-daughter assembly 10 are engaged, so that the assembled mother-daughter assembly 10 forms a closed ring structure. The cable 5 is placed in its respective straightening channel 30. Hold the outside of the mother sleeve 1 and straighten the cable.

[0083] In another preferred embodiment, the difference from the above embodiment is that a first groove and a second groove can be formed at the free ends of the mother sleeve 1 and the daughter sleeve 2 respectively. The first groove and the second groove are combined to form a dovetail groove 102. A dovetail boss is formed at the connecting end of the mother sleeve 1. Similarly, the purpose of connecting two adjacent mother and daughter assemblies 10 can be achieved.

[0084] See Figure 3 , 4 As shown:

[0085] Preferably, the mother sleeve 1 is arc-shaped, and the daughter sleeve 2 is arranged accordingly. The two wire harness straightening mechanisms are combined to form a circular wire straightening assembly. Of course, the mother sleeve 1 can also be concave (not shown), and the two wire harness straightening mechanisms are combined to form a square wire straightening assembly. Depending on the actual situation, it can also be other shapes, such as the daughter sleeve 2 and the mother sleeve 1 forming a straight line structure. When multiple straight line structure daughter sleeves 2 and mother sleeves 1 are connected end to end, the length of the wire harness straightening mechanism can be extended indefinitely, thereby expanding the straightening channel 30 in the length direction.

[0086] When in use, when the mother sleeve 1 is arc-shaped, the fitting path 20 formed between the mother sleeve 1 and the daughter sleeve 2 is arc-shaped. The two mother and daughter combined bodies 10 form a circular structure to straighten the wire harness.

[0087] When the mother sleeve 1 is concave, the fitting path 20 formed between the mother sleeve 1 and the daughter sleeve 2 can be straight. After the two mother and daughter combined bodies 10 are combined, two parallel straightening bundles are formed. In this embodiment, the mother sleeve 1 is only an arc shape.

[0088] In the above technical solution, the wire harness straightening mechanism provided by this utility model is used as follows:

[0089] See Figure 1 , 5 As shown, when the wire harness straightening mechanism is used alone, firstly, the sub-sleeve 2 and the mother sleeve 1 are combined into a half-circular sub-mother assembly 10 by screws 3 and nuts 4. When the sub-sleeve 2 is attached to one side of the mother sleeve 1, it can be used alone.

[0090] Figure 7 This diagram illustrates the usage status of the straightening component.

[0091] When the wire harness straightening mechanism is used in combination, firstly, a single mother-daughter assembly 10 is assembled, and then two mother-daughter assemblies 10 are combined. In this combination, after the first protrusion 101 and the second protrusion 201 of one mother-daughter assembly 10 are closed to form a complete dovetail boss, it engages with the dovetail groove 102 of the other mother-daughter assembly 10. The two adjacent mother-daughter assemblies 10 are connected by the dovetail groove 102 and the dovetail boss to form a straightening component.

[0092] This utility model discloses a wire straightener;

[0093] Figure 8 An isometric view of the cable straightener is shown. Figure 9 A top view of the cable straightener is shown;

[0094] This cable straightener has multiple cable straightening components, which are nested sequentially. This allows for layered cable straightening, increasing the number of cables that can be straightened and expanding the application scenarios. It also results in better layering, improved finishing quality, and further reduced cable crossover.

[0095] Preferably, a snap-fit ​​structure is connected between the wire harness straightening mechanisms of two adjacent wire straightening assemblies to position the relative positions of the two adjacent wire straightening assemblies.

[0096] The snap-fit ​​structure 6 includes a snap-fit ​​block 601 and a snap-fit ​​slot 602, wherein the snap-fit ​​block 601 can engage or disengage with the snap-fit ​​slot 602. For details, see [link to details]. Figure 8The inner wall of the outer sleeve 2 of the outer winding assembly has a slot 602, and the outer wall of the inner sleeve 1 of the inner winding assembly has a block 601. Of course, the positions of the slot 602 and the block 601 can be interchanged. The slot 602 is provided on the outer wall of the inner sleeve, and the block 601 is provided on the inner wall of the outer sleeve 2 of the outer winding assembly. The block 601 engages with the slot 602 to connect the two winding assemblies. The block 601 and the slot 602 can have a transition fit or a certain amount of interference to form a small interference fit.

[0097] The snap-fit ​​structure 6 can also be selected from the connection mechanism used in the straightening component, namely the dovetail groove and dovetail boss cooperation, or the structure in the prior art that can realize the connection of the inner and outer straightening components;

[0098] In the above technical solution, the process method for straightening wires using the wire harness straightening mechanism, straightening component, and straightener provided by this utility model includes the following steps:

[0099] Step 1: Open the sub-sleeve 2 of the assembled mother-daughter assembly 10 at a certain angle, put the cable 5 into the concave structural cavity 103 of the mother sleeve 1, close the sub-sleeve 2, and the cable 5 is located in the cable-strapping channel 30 formed by the concave structural cavity between the sub-sleeve 2 and the mother sleeve 1.

[0100] Step 2: Repeat Step 1 and assemble the second mother-daughter assembly 10 again. Insert the dovetail bosses on the two mother-daughter assemblies 10 with the two connected cables 5 into the dovetail grooves 102, and place the cables 5 in the straightening channel 30 of the annular wire harness straightening mechanism.

[0101] Step 3: After repeating Step 1, assemble the mother-daughter assembly 10 onto the inner female body 1, and engage the slot 602 of the mother-daughter assembly 10 onto the block 601 of the inner mother-daughter assembly 10. Repeat Step 2 to assemble the second outer mother-daughter assembly 10 again. The dovetail protrusions on the two mother-daughter assemblies 10 for connecting cables 5 are embedded into the dovetail grooves 102. At the same time, the slot 602 engages with the block 601, and several cables 5 are placed in the straightening channel 30 of the double-layer annular wire harness straightening mechanism.

[0102] Step 4: After assembly, all cables 5 are placed in the cable-strapping channel 30 of the double-layer ring cable straightener, so that the cables 5 cannot cross.

[0103] Pull the cable straightener in the direction of cable laying, and bundle it every certain distance. When you encounter the branch position of cable 5, open the straightening mechanism to put down the branch cable and reassemble it according to steps one, two and three.

[0104] In the above technical solution, the wire harness straightening mechanism provided by this utility model improves the quality and efficiency of wire harness sorting and straightening during base frame wiring. The wire harness position is formed and fixed by the sub-sleeve 2 and the mother sleeve 1 forming a sub-mother assembly 10, which ensures that the wire harness is not crossed and is aesthetically pleasing after forming. The fixing clamp is used to securely and firmly fix the wire harness in the base frame wire groove after sorting and then bundle it to prevent the wire harness from moving or crossing, thereby improving the efficiency and quality of the overall wiring.

[0105] Secondly, the straightening components, due to their modular design, allow for quick replacement and adjustment based on the specific requirements of different rail vehicles. When there are many branch harnesses, they can be freely assembled and disassembled according to the branch points along the laying length, achieving a reasonable layout of branch harnesses and reducing harness crossings. Therefore, the modular design facilitates flexible adjustments based on different harness specifications and wiring requirements.

[0106] In addition, the previous method of improving the operator's skill in controlling the internal wire harness to achieve the smoothness of the wire harness has been changed to use a wire harness smoothing mechanism to assist in fixing and smoothing the wire harness. This effectively improves the stability of the wiring process, reduces quality problems such as wire harness crossing and stress caused by the operator's lack of skill, saves production costs and improves product quality.

[0107] Furthermore, the straightener, due to the combination of double-layer straightening components, not only increases the number of wires that can be straightened, but also expands the application scenarios, resulting in better layering, improved finishing quality, and further reduction of wire harness crossing.

[0108] Compared with existing technologies, the above technical solution changes the operation method. Previously, operators relied on personal experience and techniques to organize and straighten wire harnesses. Now, a wire harness straightening mechanism, straightening components, and straightener are used to assist in straightening, effectively improving work efficiency. It also reduces the labor intensity of personnel, improves the original operation method, and features a modular design that allows for quick replacement of components, adapting to wire harness straightening in different vehicle models and situations. This improved operation method effectively enhances operational stability, resulting in an efficiency increase of over 50%.

[0109] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
