It can also provide power-off protection when the circuit is overloaded, short-circuited or leaking. The power distribution cabinet includes electrical components such as circuit breakers, contactors, intermediate relays, thermal relays, buttons, indicator lights, universal transfer switches and travel switches. In addition, the power distribution cabinet also includes a large number of cables. The directions of these cables are complicated and the arrangement in the power distribution cabinet is chaotic, which is not conducive to the maintenance and repair of the power distribution cabinet. Utility Model Content

[0003] The present application provides a cable bundling assembly and electrical equipment, which improve the convenience of cable bundling and enhance work efficiency.

[0004] In the first aspect, the present application provides a cable bundling assembly, which is used to fix cables to structural members in power equipment. Specifically, the cable bundling assembly includes a first wire harness and a second wire harness, and the first wire harness and the second wire harness respectively include a fixing portion and a connecting portion. Among them, the fixing portion of the first wire harness and the fixing portion of the second wire harness are used to be fixed to the structural member, and the connecting portion of the first wire harness and the connecting portion of the second wire harness are used to bundle the cables from both sides of the cable. There are multiple ways to fix the above-mentioned fixing portion and the structural member. For example, the fixing portion can be fixed to the structural member by a fastener; for another example, the fixing portion can also be fixed to the structural member by snapping. The above-mentioned two connecting portions can be connected to bundle cables, and the connection method also includes multiple ways. For example, the two connecting portions can be connected together by snapping to bundle the cables. In specific implementation, the connecting portion of the first wire harness is provided with a first snap-in structure, and the connecting portion of the second wire harness is provided with a second snap-in structure. The first snap-in structure and the second snap-in structure can be snap-in fixed, so as to bundle the cables and fix the cables relative to the structural member. In other connection methods, the two connection parts can also be connected together by fasteners or other methods to bundle the cables, which are not listed one by one in this application.

[0005] After bundling the cables with the above cable bundling assembly, the cables can be fixed relative to the structural parts, thereby preventing the cables from shaking at will and improving safety; and the cables can be arranged more neatly, improving the disordered arrangement and cross-knotting of multiple cables inside the power equipment, so that during the maintenance and inspection of the power equipment, it is convenient for the staff to quickly find the corresponding cables, thereby improving work efficiency. In addition, in the above cable bundling assembly, the two cable ties together bundle the cables, which can increase the bundling strength and make the cables less likely to loosen.

[0006] When the fixing part is specifically provided, the fixing part includes a plurality of possible structures. In one possible structure, the fixing part has a fixing hole, the fixing hole is used to accommodate a fastener, and the fastener is used to connect the fixing part and the structural member. The fastener can improve the connection reliability between the wiring harness and the structural member, so that the wiring harness is not easy to be separated from the structural member.

[0007] In a specific technical solution, the connecting portion is vertically arranged on the surface of the fixing portion, and the fixing portion includes two protruding portions, which are located on opposite sides of the connecting portion, and each protruding portion has at least one fixing hole. Each of the above-mentioned protruding portions can be fixed to the structural member by one or more fasteners, thereby further improving the fixing effect of the cable harness.

[0008] In another possible structure, the fixing portion includes a buckle, and correspondingly, the structural member has a slot that matches the buckle. During the assembly process of the cable harness and the structural member, the cable harness can be fixed to the structural member by inserting the buckle into the slot. The above operation is simple, time-saving and labor-saving, and can improve the installation efficiency of the cable harness.

[0009] In a specific technical solution, an arc-shaped pressing sheet is provided between the connecting portion and the buckle, and the pressing sheet protrudes in a direction away from the buckle, and the edge of the pressing sheet is used to abut against the surface of the structural member. During the insertion of the buckle into the slot, the edge of the pressing sheet can abut against the surface of the structural member, and then, as the buckle goes deeper, the pressing sheet gradually deforms under the squeezing action of the structural member. After the buckle is fully inserted into the slot, the deformation of the pressing sheet reaches a maximum, and has a tendency to recover the deformation. At this time, the pressing sheet exerts a pulling effect on the buckle, causing the buckle to abut against the inner wall of the slot, thereby preventing the buckle from moving in the slot. In this way, the relative stability of the wiring harness and the structural member is ensured.

[0010] In a specific technical solution, the connecting portion includes a first part and a second part connected to each other, and the first part and the second part are arranged in sequence along a direction away from the fixing portion. The width of the first part is greater than the width of the second part, and the first clip structure is located in the second part of the first wiring harness, and the second clip structure is located in the second part of the second wiring harness. In the above solution, by arranging the first clip structure or the second clip structure in the second part, the first part can have a complete structure, thereby avoiding the influence of the first clip structure and the second clip structure on the structural strength of the first part, so that the connection effect between the connecting portion and the fixing portion is better. In addition, by increasing the width of the first part, the structural strength of the first part can also be increased, thereby improving the connection effect between the connecting portion and the fixing portion.

[0011] In order to avoid stress concentration at the connection between the first part and the second part, in a specific technical solution, there is a transition connection area between the first part and the second part, and the transition connection area has two arc-shaped side surfaces, which are located on both sides of the transition connection area along the width direction, and the two arc-shaped side surfaces can be concave toward the inside of the transition connection area or convex toward the outside. In the above solution, the width of the transition connection area gradually decreases from the first part to the second part, so that the first part can smoothly transition to the first part, thereby avoiding the generation of stress concentration.

[0012] In a specific technical solution, the connecting portion is vertically arranged on the surface of the fixing portion, and a reinforcing rib is arranged between at least one side of the connecting portion and the fixing portion in the thickness direction. The reinforcing rib has a first side and a second side, the first side is connected to the connecting portion, and the second side is connected to the fixing portion. The reinforcing rib can enhance the connection strength between the connecting portion and the fixing portion, so that the connecting portion and the fixing portion are not easily broken at the connection.

[0013] In this application, for the convenience of description, the fixing part and the connecting part included in the first harness may be respectively referred to as the first fixing part and the first connecting part, and the fixing part and the connecting part included in the second harness may be respectively referred to as the second fixing part and the second connecting part. The first connecting part is provided with a first clamping structure, and the second connecting part is provided with a second clamping structure.

[0014] In a specific technical solution, the first connecting portion is provided with a plurality of first clamping structures, which are arranged at intervals in a direction away from the first fixing portion. During application, the second clamping structure can be clamped and fixed to one of the first clamping structures according to the thickness of the cable, so that the cable bundling assembly has an adjustable function.

[0015] In another specific technical solution, the second connecting portion is provided with a plurality of second clamping structures, which are arranged at intervals in a direction away from the second fixing portion. During application, the first clamping structure and one of the second clamping structures can be clamped and fixed according to the thickness of the cable, so that the cable bundling assembly has an adjustable function.

[0016] When the first clamping structure and the second clamping structure are clamped to bundle the cables, the first clamping structure and the second clamping structure include a plurality of compatible structures. In a specific technical solution, the first clamping structure includes a limiting groove, and the second clamping structure includes a first through hole and a first locking tongue arranged on the inner wall of the first through hole. During use, the first connecting part can pass through the first through hole, and by inserting the first locking tongue into the limiting groove, the first connecting part can be prevented from moving further in the first through hole. At this time, the first connecting part and the second connecting part are locked, and the cables are bundled.

[0017] In another specific technical solution, the first clamping structure includes a ratchet, and the second clamping structure includes a second through hole and a second locking tongue disposed on the inner wall of the second through hole. During use, the first connecting part can pass through the second through hole, and by making the second locking tongue and the stop surface of the ratchet abut against each other, the first connecting part can be prevented from moving further in the second through hole. At this time, the first connecting part and the second connecting part are locked, and the cables are bundled.

[0018] In the specific setting, ratchets can be provided on any side of the first connection part along the thickness direction, or ratchets can be provided on both sides of the first connection part along the thickness direction. In the latter setting, the inner wall of the second via hole has two second locking tongues, and each second locking tongue is used to abut against the ratchet on the corresponding side after the connection part of the first wiring harness passes through the second via hole. By making the two second locking tongues abut against the ratchets on the corresponding sides respectively, the connection strength of the first connection part and the second connection part can be improved, so that the first connection part and the second connection part are not easy to be disengaged.

[0019] In the second aspect, the present application also provides an electric device, which includes a housing, electrical components, structural components, and cables such as a cable bundling assembly in any of the above technical solutions. The electrical components and the structural components are fixed in the housing, and the electrical components and the cables are electrically connected, and the structural components are located on the extension path of the cables. As for the cable bundling assembly, the fixed portion of the first wire harness and the fixed portion of the second wire harness are fixed to the structural component, the connecting portion of the first wire harness and the connecting portion of the second wire harness are located on both sides of the cable, and the first clamping structure and the second clamping structure are clamped and fixed. Under the action of the cable bundling assembly, the cables are fixed to the structural components.

[0020] In the above-mentioned electric power equipment, the cables are bundled and fixed by using the cable bundling assembly, so that the cables are arranged in an orderly manner, thereby providing convenience for the maintenance and repair of the electric power equipment and improving work efficiency.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. However, the example implementation can be implemented in various forms and should not be construed as being limited to the implementations set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all illustrated by taking the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings of the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0032] It should be noted that specific details are described in the following description to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the embodiments of the present application. Therefore, the present application is not limited to the specific implementation methods disclosed below.

[0033] In order to facilitate the understanding of the technical solution provided by the embodiment of the present application, its application scenario is first introduced below. With the development of society, power equipment has become an indispensable tool in people's production and life, bringing great convenience to people. There are many types of power equipment and various functions. In a power equipment, a variety of electrical components are included inside, and different electrical components are electrically connected by cables. These electrical components work together to realize the function of the power equipment. The above-mentioned power equipment can specifically be a distribution device, such as a distribution cabinet. Alternatively, the above-mentioned power equipment can also be of other types, which are not listed one by one in this application. Taking the distribution cabinet as an example, the distribution cabinet includes electrical components such as circuit breakers, contactors, intermediate relays, thermal relays, buttons, indicator lights, universal conversion switches and travel switches. In addition to electrical components, the distribution cabinet also includes a plurality of cables, which can be connected to the above-mentioned electrical components so that the above-mentioned electrical components work together, so that the distribution cabinet can realize functions such as power distribution, power control, power protection or status monitoring. Since there are a large number of cables and their routes are complicated, it takes a lot of time and energy to find a certain cable during the maintenance and inspection of the distribution cabinet, resulting in low work efficiency.

[0034] In view of this, an embodiment of the present application provides a cable bundling assembly and an electric power device, which bundles and fixes the cables so that the cables are arranged in an orderly manner, thereby providing convenience for the maintenance and repair of the electric power equipment and improving work efficiency.

[0035] Figure 1 A schematic diagram of an assembly of a cable bundling assembly and a structural member provided in an embodiment of the present application, Figure 2 for Figure 1 The schematic diagram of the structure of the cable bundling assembly is shown in FIG. Figure 1 and Figure 2 As shown, in one embodiment, the cable bundling assembly 1 can be assembled on a structural member 2 in an electric power device, and is used to fix the cable 4 to the structural member 2. Specifically, the cable bundling assembly 1 includes two wire harnesses 10, and each wire harness 10 includes a fixing portion 11 and a connecting portion 12. Among them, with respect to the fixing portion 11 in the above two wire harnesses 10, the fixing portion 11 can be fixed to the structural member 2. When specifically set, the fixing method of the fixing portion 11 and the structural member 2 includes a variety of options. For example, the fixing portion 11 and the structural member 2 can be fixed by fasteners; for another example, the fixing portion 11 and the structural member 2 can also be fixed by snap-fitting; of course, the fixing portion 11 and the structural member 2 can also be fixed by other methods, which are not listed one by one in this application. Under different fixing methods, the fixing portion 11 and the structural member 2 respectively have matching structures, so that the two can be fixed by corresponding fixing methods.

[0036] Please continue to refer to Figure 1 and Figure 2 As for the connection parts 12 in the above-mentioned two cable ties 10, the two connection parts 12 are used to bundle the cables 4 from both sides of the cables 4. Among them, one of the two connection parts 12 is provided with a first clamping structure 121, and the other is provided with a second clamping structure 122. The first clamping structure 121 and the second clamping structure 122 have different structures, and the two are adapted to each other and can be clamped and fixed. When bundling the cables 4, the fixing parts 11 of the above-mentioned two cable ties 10 can be fixed to the structural member 2; then, the connection parts 12 of the above-mentioned two cable ties 10 are relatively close from both sides of the cables 4; finally, the first clamping structure 121 and the second clamping structure 122 are clamped and fixed, so as to tighten the cables 4 and fix the cables 4 relative to the structural member 2. During the bundling process, by bringing the connecting parts 12 of the two cable ties 10 relatively close to each other from both sides of the cable 4 for bundling, each cable ties 10 does not need to wrap around the cable 4 for one week, thereby shortening the moving path of the cable ties 10, reducing the difficulty of bundling and improving convenience; at the same time, it also reduces the space requirements for the bundling operation, so that the bundling operation can be successfully completed in some narrower spaces.

[0037] In specific applications, the number of cable bundling assemblies 1 can be one or more. Taking two cable bundling assemblies 1 as an example, the two cable bundling assemblies 1 can bundle and fix two different groups of cables 4 to different positions of the same structural member 2, or bundle and fix two different groups of cables 4 to two different structural members 2. Of course, the above two cable bundling assemblies 1 can also bundle and fix different parts of the same group of cables 4 to two different structural members 2. After bundling the cables 4 with the above cable bundling assembly 1, the cables 4 can be fixed relative to the structural member 2, thereby avoiding the random shaking of the cables 4 and improving safety; and, the arrangement of the cables 4 can also be made more organized, improving the phenomenon of chaotic arrangement and cross-knotting of multiple cables 4 inside the power equipment, so that in the process of maintenance and inspection of the power equipment, it is convenient for the staff to quickly find the corresponding cables 4, thereby improving work efficiency. In addition, in the above cable bundling assembly 1, the two wire bundles 10 jointly play a bundling role on the cables 4, which can increase the bundling strength and make the cables 4 not easy to loosen.

[0038] When the cable bundling assembly 1 is assembled to the structural member 2, there are multiple assembly methods. Figure 2 As shown, in the cable bundling assembly 1, the fixing portion 11 of each wiring harness 10 has a fixing hole 110, and the fixing hole 110 is used to accommodate a fastener, and the fastener can fix the fixing portion 11 to the structural member 2, so that the wiring harness 10 is fixed relative to the structural member 2. Among them, the fixing hole 110 can be a through hole with a smooth inner wall, or a through hole with a threaded inner wall. The number of fixing holes 110 can be one or more. In order to improve the fixing effect of the wiring harness 10, in a specific embodiment, the fixing portion 11 has a plurality of fixing holes 110, and the plurality of fixing holes 110 can enable the fixing portion 11 to be fixed to the structural member 2 through a plurality of fasteners, so that the wiring harness 10 is more stable relative to the structural member 2 and is not easy to be separated from the structural member 2, thereby improving the fixing effect of the wiring harness 10.

[0039] In the above embodiments, the type of fastener includes multiple options, for example, the fastener may be a screw, a bolt or a pin. For different fasteners, the structural member 2 is provided with a structure that matches the fastener. Taking a screw as an example, in a specific embodiment, the structural member 2 is provided with a threaded hole that matches the screw, and the screw passes through the fixing hole 110 and is inserted into the threaded hole, so that the fixing portion 11 and the structural member 2 are relatively fixed.

[0040] Please continue to refer to Figure 2In one embodiment, the connecting portion 12 is vertically disposed on the surface of the fixing portion 11, and the fixing portion 11 includes two protruding portions 111, which protrude from the edge of the connecting portion 12 and are located on opposite sides of the connecting portion 12, and each protruding portion 111 has at least one fixing hole 110. Each protruding portion 111 can be fixed to the structural member 2 by one or more fasteners, thereby further improving the fixing effect of the cable harness 10.

[0041] In a specific configuration, the connecting portion 12 is a strip-shaped structure, and the fixing portion 11 is located at the end of the connecting portion 12 along the length direction, wherein the two protruding portions 111 can be located at both sides of the connecting portion 12 along the thickness direction, or can also be located at both sides of the connecting portion 12 along the width direction. Figure 1 and Figure 2 , taking the structural member 2 as a beam as an example, in a specific embodiment, the two protruding portions 111 in the fixing portion 11 are located on both sides of the connecting portion 12 along the width direction, and the width direction of the connecting portion 12 is consistent with the width direction of the structural member 2. In another specific embodiment, the two protruding portions in the fixing portion are located on both sides of the connecting portion along the thickness direction, and the thickness direction of the connecting portion is consistent with the extension direction of the structural member. Since the two protruding portions in the fixing portion do not occupy space in the width direction of the structural member, the width of the above-mentioned structural member can be smaller.

[0042] In addition to the above structural form, in another embodiment, the fixing portion includes an annular flange structure, the flange structure protrudes from the peripheral edge of the connecting portion, and the flange structure has a plurality of fixing holes. In specific configuration, the plurality of fixing holes can be evenly arranged along the circumference, so that the fasteners are evenly distributed around the connecting portion, thus further improving the fixing effect of the cable tie.

[0043] In the above embodiments, by relatively fixing the fixing portion 11 and the structural member 2 under the connection of the fastener, the fixing effect between the cable tie 10 and the structural member 2 can be improved, so that the cable tie 10 is not easy to be separated from the structural member 2. For example, in some scenarios where the cable 4 needs to be kept in a bent state, under the connection of the fastener, the cable tie 10 can withstand the rebound force generated by the cable 4 recovering from deformation, and is not easy to be separated from the structural member 2, so that the bundling effect of the cable 4 is better and the bent shape can be maintained.

[0044] Figure 3 Another assembly diagram of the cable bundling assembly and the structural member provided in the embodiment of the present application is shown in FIG. Figure 4 for Figure 3 The schematic diagram of the structure of the cable bundling assembly is shown in FIG. Figure 3 and Figure 4As shown, in the cable bundling assembly 1, the fixing portion 11 of each cable tie 10 has a buckle 112, and correspondingly, the structural member 2 is provided with a slot, and the buckle 112 is provided in the slot so that the fixing portion 11 is fixed relative to the structural member 2. In the specific configuration, the buckle 112 is an elastic structure, and the buckle 112 can be deformed during the insertion into the slot, so that the volume is reduced, so that it is easy to extend into the slot. After being inserted into place, the buckle 112 can restore the deformation and contact the inner wall of the slot, so that it is not easy to fall out of the slot.

[0045] Figure 5 A schematic diagram of a partial structure of a wiring harness provided in an embodiment of the present application, such as Figure 5 As shown, in one embodiment, the buckle 112 includes a main body 1121 and two elastic hooks 1122 located on both sides of the main body 1121. The main body 1121 extends along the first direction X, and the main body 1121 has a first end and a second end distributed along the first direction X, wherein the first end is close to the connecting portion 12, and the second end is away from the connecting portion 12. The distance between the elastic hook 1122 and the main body 1121 gradually increases in the direction from the second end to the first end. The shape of the slot is adapted to the above-mentioned buckle 112, and the slot has a wall surface that abuts against the elastic hook 1122. When the above-mentioned buckle 112 is inserted into the slot, the two elastic hooks 1122 are pressed toward the main body 1121, or in other words, the two elastic hooks 1122 are relatively retracted. After the buckle 112 completely enters the slot, the two elastic hooks 1122 open relative to the main body 1121 and gradually return to their initial shape. At this time, the end of the elastic hook 1122 away from the main body 1121 abuts against the inner wall of the slot, making it difficult for the buckle 112 to fall out.

[0046] Please continue to refer to Figure 5 In one embodiment, an arc-shaped pressing piece 113 is provided between the connecting portion 12 and the buckle 112, and the pressing piece 113 protrudes in a direction away from the buckle 112, or in other words, the pressing piece 113 protrudes toward the connecting portion 12. In the process of inserting the buckle 112 into the slot, the edge of the pressing piece 113 can abut against the surface of the structural member. Then, as the buckle 112 goes deeper, the pressing piece 113 will be squeezed by the structural member and deformed, and the deformation of the pressing piece 113 will gradually increase, and the pressing piece 113 will also be gradually flattened. After the buckle 112 is fully inserted into the slot, the deformation of the pressing piece 113 reaches the maximum, and has a tendency to recover the deformation. At this time, the pressing piece 113 exerts a pulling effect on the buckle 112, and causes the buckle 112 to abut against the inner wall of the slot. In this way, the buckle 112 is prevented from moving in the slot, so that the cable harness 10 and the structural member remain relatively stable.

[0047] In a specific embodiment, the edge of the pressing sheet 113 has a rounded corner, and during the process of inserting the buckle 112 into the slot, the rounded corner can contact the surface of the structural member and slide on the surface of the structural member as the pressing sheet 113 deforms. The rounded corner can reduce the friction between the pressing sheet 113 and the structural member, making it easier to insert the buckle 112 into the slot.

[0048] In the above cable bundling assembly 1, the fixing portions 11 of the two cable ties 10 may adopt the same structural form or different structural forms. Figure 2 The structural forms shown, or both adopt Figure 4 For example, the fixing portion 11 of one of the cable ties 10 may be Figure 2 In the structural form shown, the fixing portion 11 of another cable tie 10 can be Figure 4 The structural form shown.

[0049] When the cable bundling assembly 1 is assembled to the structural member 2, the fixing portions 11 of the two cable tying members 10 can be fixed side by side to the structural member 2. With respect to the structural member 2, the two fixing portions 11 of the two cable tying members 10 can be arranged adjacent to each other or spaced apart. Figure 1 As shown, in one embodiment, the fixing portions 11 of the two cable ties 10 are spaced apart relative to the structural member 2, so that the cable 4 can pass through the gap between the two fixing portions 11 and the cable 4 can be close to the surface of the structural member 2 after being tightened, thereby improving the fixing effect of the cable 4.

[0050] For reference Figure 1 and Figure 2 When the connection part 12 is specifically provided, the connection part 12 may be a strip-shaped structure. The connection part 12 has a length dimension, a width dimension and a thickness dimension. When the connection part 12 is in a straight state, the length dimension is the dimension of the connection part 12 along the first direction X, the width dimension is the dimension of the connection part 12 along the second direction Y, and the thickness dimension is the dimension of the connection part 12 along the third direction Z, and the length dimension is greater than the width dimension, and the width dimension is greater than the thickness dimension. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0051] Continue to refer Figure 1 and Figure 2, the connecting portion 12 includes a first portion 123 and a second portion 124 connected to each other, and the first portion 123 and the second portion 124 are arranged in sequence in a direction away from the fixing portion 11. That is, the first portion 123 is located between the fixing portion 11 and the second portion 124, or in other words, one end of the first portion 123 is connected to the fixing portion 11, and the other end of the first portion 123 away from the fixing portion 11 is connected to the second portion 124. If the two harnesses 10 in the cable bundling assembly 1 are respectively recorded as a first harness 10a and a second harness 10b, the first portion 123 of the first harness 10a is the same as the first portion 123 of the second harness 10b, and the second portion 124 of the first harness 10a and the second portion 124 of the second harness 10b are different. Specifically, the second portion 124 of the first harness 10a is provided with a first clamping structure 121, and the second portion 124 of the second harness 10b is provided with a second clamping structure 122. The first clamping structure 121 and the second clamping structure 122 have different structures, are compatible with each other, and can be clamped and fixed.

[0052] In the above embodiment, by setting the first clip structure 121 or the second clip structure 122 on the second part 124, the first part 123 can have a complete structure, thereby avoiding the influence of the first clip structure 121 and the second clip structure 122 on the structural strength of the first part 123, so that the connection effect between the connecting part 12 and the fixing part 11 is better.

[0053] When setting the size of the first part 123 and the second part 124, the length of the first part 123 can be smaller than the length of the second part 124, so that the second part 124 occupies a larger proportion in the length direction of the connecting part 12, thereby providing space for arranging multiple first clamping structures 121 or multiple second clamping structures 122, so that the first cable tie 10a and the second cable tie 10b have the function of adjusting the tightness when clamping; the width of the first part 123 can also be larger than the width of the second part 124, so that the connection strength between the connecting part 12 and the fixing part 11 is enhanced. Of course, the width of the second part 124 can also be set to be equal to the width of the first part 123, so that the second part 124 and the first part 123 both have a wider size.

[0054] For reference Figure 4 and Figure 5In one embodiment, the connecting portion 12 is vertically arranged on the surface of the fixing portion 11, and a reinforcing rib 125 is arranged between at least one side of the connecting portion 12 and the fixing portion 11 along the thickness direction. The connecting portion 12 and the fixing portion 11 can form an angular space at the connection, and the reinforcing rib 125 is located in the angular space. The reinforcing rib 125 has a first side and a second side, wherein the first side is connected to the connecting portion 12, and the second side is connected to the fixing portion 11. The first side and the second side are perpendicular to each other and form a right triangle structure. The number of the reinforcing rib 125 can be one or more, and can be flexibly set according to needs. The reinforcing rib 125 can enhance the connection strength between the connecting portion 12 and the fixing portion 11, so that the connecting portion 12 and the fixing portion 11 are not easily broken at the connection.

[0055] like Figure 5 As shown, in a specific embodiment, the fixing portion 11 includes a bottom plate 114, the bottom plate 114 is connected to the first portion 123 of the connecting portion 12, the first portion 123 includes a first surface and a second surface arranged along the thickness direction, at least one of the first surface and the second surface and the bottom plate 114 form an angular space, and a plurality of reinforcing ribs 125 are arranged in the angular space. The plurality of reinforcing ribs 125 are arranged at intervals along the second direction Y. The thickness direction is consistent with the third direction Z.

[0056] Please continue to refer to Figure 4 and Figure 5 , a transition zone 126 is provided between the first portion 123 and the second portion 124 of the connection portion 12, the width of the transition zone 126 gradually decreases in the direction away from the first portion 123, and the transition zone 126 has two arc-shaped side surfaces on both sides along the width direction. The width direction and the second direction Y are consistent. In the specific setting, the two side surfaces can be symmetrically arranged about the central axis of the connection portion 12, and each side surface can be convex to the outside of the transition zone 126, or can be concave to the inside of the transition zone 126. The transition zone 126 plays a transition role between the first portion 123 and the second portion 124, avoiding the phenomenon of stress concentration.

[0057] In the embodiment of the present application, for the convenience of description, the fixing portion 11 and the connecting portion 12 included in the first cable tie 10a can be respectively recorded as the first fixing portion 11a and the first connecting portion 12a, and the fixing portion 11 and the connecting portion 12 included in the second cable tie 10b can be respectively recorded as the second fixing portion 11b and the second connecting portion 12b. The first connecting portion 12a is provided with a first clamping structure 121, and the second connecting portion 12b is provided with a second clamping structure 122. The first clamping structure 121 and the second clamping structure 122 are fixed by clamping, so that the first connecting portion 12a and the second connecting portion 12b are connected.

[0058] In order to enable the cable bundling assembly 1 to bundle cables 4 of different thicknesses, the number of the first clamping structures 121 and the second clamping structures 122 can be set, so that the cable bundling assembly 1 has an adjustable function. Figure 2 As shown, in one embodiment, the first connecting portion 12a includes a plurality of first clamping structures 121, which are arranged at intervals in a direction away from the first fixing portion 11a. In the application process, the first clamping structures 121 and the second clamping structures 122 at different positions can be clamped and fixed according to the thickness of the cable 4, so that the cable bundling assembly 1 has an adjustable function.

[0059] In another embodiment, the second connecting portion 12b includes a plurality of second clamping structures 122, which are arranged at intervals in a direction away from the second fixing portion 11b. In the application process, the first clamping structure 121 and the second clamping structures 122 at different positions can be clamped and fixed according to the thickness of the cable 4, so that the cable bundling assembly 1 has an adjustable function.

[0060] In other embodiments, the first connecting portion 12a includes a plurality of first clamping structures 121, and the plurality of first clamping structures 121 are arranged at intervals in a direction away from the first fixing portion 11a. Meanwhile, the second connecting portion 12b includes a plurality of second clamping structures 122, and the plurality of second clamping structures 122 are arranged at intervals in a direction away from the second fixing portion 11b. In the application process, the first clamping structure 121 and the second clamping structure 122 can be flexibly selected according to the thickness of the cable 4, so as to clamp and fix the cable 4, thereby bundling the cable 4.

[0061] When the first clamping structure 121 and the second clamping structure 122 are clamped together to bundle the cables 4, the first clamping structure 121 and the second clamping structure 122 include a variety of compatible structures. Figure 2 As shown, in one embodiment, the first clamping structure 121 specifically includes a limiting groove 1211, and the second clamping structure 122 includes a first through hole 1221 and a first locking tongue 1222 disposed on the inner wall of the first through hole 1221. During use, the first connecting portion 12a can pass through the first through hole 1221, and the longer the length of the first connecting portion 12a passing through the first through hole 1221 is, the tighter the bundling effect is; conversely, the shorter the length of the first connecting portion 12a passing through the first through hole 1221 is, the looser the bundling effect is. By inserting the first locking tongue 1222 into the limiting groove 1211, the first connecting portion 12a can be prevented from moving further in the first through hole 1221.

[0062] Please continue to refer to Figure 2, the first connecting part 12a is provided with a plurality of limiting grooves 1211, and the plurality of limiting grooves 1211 are arranged at intervals in a direction away from the first fixing part 11a. When the first connecting part 12a passes through the first through hole 1221, the limiting grooves 1211 provided on the first connecting part 12a will also pass through the first through hole 1221 in sequence. When the first connecting part 12a and the second connecting part 12b are tightly clamped on the surface of the cable 4, the first locking tongue 1222 on the inner wall of the first through hole 1221 can be inserted into the limiting groove 1211 closest to the first locking tongue 1222, so that the first connecting part 12a cannot move further. At this time, the first connecting part 12a and the second connecting part 12b are locked, and the cable 4 is bundled. During use, the length of the first connecting part 12a passing through the first through hole 1221 can be controlled according to the thickness of the cable 4 to be bundled, and the first locking tongue 1222 can be inserted into the limiting groove 1211 closest to the first locking tongue 1222, so that the first connecting part 12a and the second connecting part 12b can tighten the cable 4.

[0063] In another embodiment, the first snap-fit ​​structure 121 includes a limiting groove 1211, and the second snap-fit ​​structure 122 includes a protrusion. During use, the first connection part 12a can be overlapped on the side of the second connection part 12b having the protrusion, and then the protrusion is snapped into the limiting groove 1211, so that the first connection part 12a and the second connection part 12b are locked. The number of protrusions can be one, two or other numbers, and the present application does not specifically limit it. In a specific embodiment, the first connection part 12a is provided with two protrusions, and the spacing between the protrusions is consistent with the spacing between the limiting grooves 1211. During use, the two protrusions can be snapped into the corresponding limiting grooves 1211, thereby strengthening the connection effect between the first connection part 12a and the second connection part 12b, so that the first connection part 12a and the second connection part 12b are not easy to disengage.

[0064] Figure 6 A schematic diagram of an assembly of two wiring harnesses provided in an embodiment of the present application is shown in FIG. Figure 6As shown, in one embodiment, the first clamping structure 121 includes a ratchet 1212, and the ratchet 1212 has a guide surface and a stop surface. The guide surface is inclined relative to the surface of the first connection part 12a, or the angle between the guide surface and the surface of the first connection part 12a is less than 90°. The stop surface can be inclined relative to the surface of the first connection part 12a, or can be vertically arranged relative to the surface of the first connection part 12a, or the angle between the stop surface and the surface of the first connection part 12a is less than or equal to 90°. The second clamping structure 122 includes a second through hole 1223 and a second locking tongue 1224 arranged on the inner wall of the second through hole 1223. During use, the first connection part 12a can pass through the second through hole 1223, and by making the second locking tongue 1224 abut against the stop surface of the ratchet 1212, the first connection part 12a can be prevented from moving further in the second through hole 1223.

[0065] Please continue to refer to Figure 6 , the first connection part 12a is provided with ratchet teeth 1212, and the ratchet teeth 1212 are arranged at intervals in the direction away from the first fixing part 11a. When the first connection part 12a passes through the second through hole 1223, the ratchet teeth 1212 provided on the surface of the first connection part 12a will also pass through the second through hole 1223 in sequence. When the first connection part 12a and the second connection part 12b are tightly clamped on the surface of the cable 4, the second locking tongue 1224 on the inner wall of the second through hole 1223 can be abutted against the stop surface of the ratchet tooth 1212 closest to the second locking tongue 1224, so that the first connection part 12a cannot move further. At this time, the first connection part 12a and the second connection part 12b are locked, and the cable 4 is bundled. During use, the length of the second connecting part 12b passing through the second through hole 1223 can be controlled according to the thickness of the cable 4 to be bundled, and the second locking tongue 1224 can be abutted against the stop surface of the ratchet 1212 closest to the second locking tongue 1224, so that the first connecting part 12a and the second connecting part 12b can tighten the cable 4.

[0066] In a specific configuration, the second locking tongue 1224 is tilted, one end of the second locking tongue 1224 is connected to the inner wall of the second through hole 1223, and the other end of the second locking tongue 1224 extends in a direction away from the inner wall. When the second locking tongue 1224 is subjected to a squeezing force, the second locking tongue 1224 can approach the inner wall of the second through hole 1223. When the squeezing force disappears, the second locking tongue 1224 can return to its initial position. In the process of the first connecting portion 12a passing through the second through hole 1223, the ratchet 1212 passes through the second locking tongue 1224 in sequence. Taking any ratchet 1212 as an example, the ratchet 1212 will squeeze the second locking tongue 1224 during the process of passing through the second locking tongue 1224, so that the second locking tongue 1224 is close to the inner wall of the second through hole 1223; after the ratchet 1212 passes through the second locking tongue 1224, the second locking tongue 1224 returns to the initial position, and the end of the second locking tongue 1224 away from the inner wall of the second through hole 1223 can abut against the stop surface of the ratchet 1212, so that the ratchet 1212 cannot retreat. At this time, the first connecting portion 12a will not be easily withdrawn from the second through hole 1223.

[0067] In some embodiments, the first clamping structure 121 includes a pair of ratchet teeth 1212 located on both sides of the first connecting portion 12a along the thickness direction, and the pair of ratchet teeth 1212 can be symmetrically arranged with respect to the first connecting portion 12a. Correspondingly, the second clamping structure 122 includes two second locking tongues 1224 located on the inner wall of the second through hole 1223, and each second locking tongue 1224 is used to abut against the stop surface of the ratchet teeth 1212 on the corresponding side after the second connecting portion 12b passes through the second through hole 1223. In the above embodiment, by making the two second locking tongues 1224 abut against the ratchet teeth 1212 on the corresponding side, the connection strength of the first connecting portion 12a and the second connecting portion 12b can be improved, so that the first connecting portion 12a and the second connecting portion 12b are not easy to be disengaged.

[0068] Based on the same technical concept, an embodiment of the present application also provides an electric power device. Figure 7 A schematic diagram of a structure of an electric power device provided in an embodiment of the present application, such as Figure 7 As shown, in one embodiment, the power device includes a housing 5, a structural member 2, an electrical device 3 and a cable 4, wherein the structural member 2 and the electrical device 3 are fixed in the housing 5, the structural member 2 is located on the extension path of the cable 4, and the electrical device 3 and the cable 4 are electrically connected. In order to fix the cable 4 to the structural member 2, the power device also includes the cable bundling assembly 1 described in any of the above embodiments. Figure 1 and Figure 7In the cable bundling assembly 1, the fixing portion 11 of the first cable tie 10a and the fixing portion 11 of the second cable tie 10b are both fixed to the structural member 2, and the connecting portion 12 of the first cable tie 10a and the connecting portion 12 of the second cable tie 10b are located on both sides of the cable 4, wherein the connecting portion 12 of the first cable tie 10a has a first clamping structure 121, and the connecting portion 12 of the second cable tie 10b has a second clamping structure 122, and the first clamping structure 121 and the second clamping structure 122 are clamped and fixed. Under the action of the above cable bundling assembly 1, the cable 4 is fixed to the structural member 2.

[0069] Taking the power equipment as a power distribution cabinet as an example, the structural member 2 may be a beam or a reinforcing rib inside the power distribution cabinet, or the structural member 2 may be a component specially arranged inside the power distribution cabinet and used to cooperate with the cable 4 bundling assembly to bundle the cables 4. By bundling the cables 4 with the cable bundling assembly 1, the space occupied by the cables 4 inside the power distribution cabinet can be reduced, making the routing of the cables 4 more organized, and providing convenience for the maintenance and repair of the power equipment.
