Description

Technical Field

[0001] This utility model relates to the field of electrical cabinets, and in particular to a wire harness fixing device and an electrical cabinet. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. They typically contain a number of wire harnesses for connecting various circuit components. After the wire harnesses are connected to the circuit components, they need to be installed, that is, fixed inside the electrical cabinet to prevent them from being scattered haphazardly within the cabinet.

[0003] In the prior art, Chinese utility model patent CN219611013U discloses an electrical protection device, including an electrical cabinet body. Inside the electrical cabinet body is a wire harness positioning mechanism that matches electrical components. The wire harness positioning mechanism includes a positioning plate connected to the inner wall of the electrical cabinet body via a connecting column. The positioning plate has a mounting block via a mounting assembly, and a wire harness limiting hole is formed between the mounting block and the positioning plate. This technology facilitates the individual fixing of wire harnesses, preventing tangling and ensuring safety during use. Furthermore, it facilitates the location of wire harnesses, allowing workers to quickly and easily disassemble and replace them individually, making operation convenient.

[0004] However, due to the different internal layouts and wiring harness positions of different electrical cabinets, the position of the wiring harness limiting holes cannot be adjusted when using the above technical solutions, which causes bending and pulling of the wiring harness during wiring, affecting the service life of the wiring harness. Utility Model Content

[0005] To address the technical problem of inflexible wiring harness fixing devices in electrical cabinets affecting the service life of wiring harnesses, this invention provides a wiring harness fixing device and electrical cabinet that can adjust the fixing position according to the wiring harness location, greatly avoiding bending and pulling of the wiring harness and improving the flexibility of wiring.

[0006] In a first aspect, this utility model provides a wire harness fixing device to solve the above-mentioned technical problems, including a fixing rod, at least two movable seats are movably arranged inside the fixing rod, the movable seats can move along the length direction of the fixing rod, a wire harness conduit is rotatably arranged at the lower part of the movable seat, the wire harness conduit has an L-shaped structure, the wire harness conduit includes a guide part one and a guide part two, the guide part two is rotatably connected to the lower part of the movable seat, and the guide part one can rotate in a vertical plane.

[0007] This invention, by setting a movable base and a wire harness conduit, can adjust the position of the movable base and the opening orientation of the wire harness conduit according to the position of the wire harness. This avoids the problem that the distribution of the wiring positions of the wire harness and electrical components and the fixed positions of the wire harness cannot be set along the natural extension direction of the wire harness. This avoids bending and pulling of the wire harness at the wiring positions, prevents the wire harness from being stressed, and extends the service life of the wire harness.

[0008] Furthermore, a transition bend is provided between the first guide section and the second guide section.

[0009] This invention avoids the wire harness from bending due to abrupt angle changes within the wire harness conduit by setting a transition bend, thereby further extending the service life of the wire harness and facilitating the wire harness to extend out from the guide section.

[0010] Furthermore, a groove is provided on the fixed rod along its length, and a boss is provided on the upper part of the two vertical walls of the groove. The movable seat is disposed in the groove and located below the boss. A limiting member is provided on the top of the movable seat. The limiting member has a T-shaped structure and includes a head and a connecting part. The connecting part is threadedly connected to the movable seat. The head is located on the upper part of the boss. When the head abuts against the boss, the position of the movable seat in the groove is locked.

[0011] This invention can lock the position of the movable seat by setting a limiting component, so as to prevent the movable seat from moving under the action of external force and causing pulling on the wire harness.

[0012] Furthermore, a connecting seat is provided at the lower part of the movable seat, and the guide part is rotatably disposed on the connecting seat.

[0013] Furthermore, it also includes two vertically arranged support rods, with the two ends of the fixing rod respectively sleeved on the corresponding support rods. The support rods are also provided with axially movable limit components, which can be locked on the support rods and can contact the fixing rods.

[0014] This novel design allows for adjustment of the position of the fixing rod using a support rod and a limiting assembly, matching the height of the electrical components and making it more flexible in use.

[0015] Furthermore, the limiting component includes a limiting sleeve, which is sleeved on the support rod. The limiting sleeve is divided into two sub-sleeves along its axial center plane. The upper end face of the sub-sleeve can contact the lower end face of the fixing rod. A connecting lug is provided on the outer circular surface of the sub-sleeve. The connecting lugs corresponding to the two sub-sleeves are connected by connecting bolts.

[0016] This utility model uses a two-half structure limiting sleeve to facilitate adjustment.

[0017] Secondly, this utility model also provides an electrical cabinet, including a cabinet body and the aforementioned wire harness fixing device. Two support rods are arranged opposite to each other inside the cabinet body. An electrical mounting rod is also horizontally arranged inside the cabinet body, and multiple mounting holes are provided on the electrical mounting rod along its length.

[0018] Furthermore, mounting plates are vertically installed on the two opposing inner walls of the cabinet, and multiple mounting holes are provided on the mounting plates along their height direction. A connecting plate is provided at the end of the electrical mounting rod, and the connecting plate is connected to the mounting plate through the mounting holes at any height.

[0019] This invention allows for more flexible use by adjusting the position of the electrical mounting rod according to the location of the electrical components and the available installation space by setting up a mounting plate.

[0020] Furthermore, the cabinet body has two cabinet doors facing each other.

[0021] This utility model facilitates internal maintenance by providing two cabinet doors.

[0022] As can be seen from the above technical solutions, this utility model has the following advantages:

[0023] This utility model provides a wire harness fixing device and an electrical cabinet. By setting a movable base and a wire harness conduit, the position of the movable base and the opening orientation of the wire harness conduit can be adjusted according to the position of the wire harness. This avoids the problem that the distribution of the wiring positions and fixing positions of the wire harness and electrical components cannot be set along the natural extension direction of the wire harness, thereby preventing bending and pulling of the wire harness at the wiring positions, avoiding stress on the wire harness, and extending the service life of the wire harness. By setting a transition bend, the wire harness is prevented from bending due to a sharp angle change within the wire harness conduit, further extending the service life of the wire harness, while facilitating the wire harness to extend from the guide section. By setting a limiting component, the position of the movable base can be locked, preventing the movable base from moving under external force and pulling on the wire harness. By using a support rod and a limiting component, the position of the fixing rod can be adjusted to match the height of the electrical components, making it more flexible to use. The limiting sleeve with a two-half structure facilitates adjustment operation. By setting an mounting plate, the position of the electrical mounting rod can be adjusted according to the position of the electrical components and the installation space, making it more flexible to use. By setting two cabinet doors, it is convenient to maintain the interior. Attached Figure Description

[0032] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0034] like Figure 1As shown in the figure, this specific embodiment provides a wire harness fixing device, including a fixing rod 3, a movable seat 5, and a wire harness conduit 7; at least two movable seats 5 are movably arranged inside the fixing rod 3, and the movable seats 5 can move along the length direction of the fixing rod 3. The wire harness conduit 7 is rotatably arranged at the lower part of the movable seat 5. The wire harness conduit 7 has an L-shaped structure and includes a first guide part 702 and a second guide part 703. The second guide part 703 is rotatably connected to the lower part of the movable seat 5. The first guide part 702 can rotate in a vertical plane, and a transition bend 701 is provided between the first guide part 702 and the second guide part 703.

[0035] This specific embodiment, by setting up a movable base 5 and a wire harness conduit 7, allows the position of the movable base 5 and the opening orientation of the wire harness conduit 7 to be adjusted according to the position of the wire harness during use. This ensures that the fixed position of the wire harness is close to the wiring position. Compared with the prior art, this avoids the problem that the distribution of the wiring position and the fixed position of the wire harness cannot be set along the natural extension direction of the wire harness. This prevents the wire harness from bending and pulling at the wiring position, avoids stress on the wire harness, and extends the service life of the wire harness.

[0036] To further prevent the wire harness from bending and affecting its service life, such as Figure 1 As shown, in this specific embodiment, a transition bend 701 is provided between guide part one 702 and guide part two 703; this setting avoids the wire harness from bending due to a sharp angle change in the wire harness guide tube 7, further extending the service life of the wire harness, and at the same time facilitating the wire harness to extend out from guide part two 703.

[0037] To prevent the movable seat 5 from moving under external force and causing pulling on the wiring harness, such as Figure 1 As shown, in this specific embodiment, a sliding groove 10 is provided on the fixed rod 3 along its length direction. A boss 4 is provided on the upper part of each of the two vertical walls of the sliding groove 10. The movable seat 5 is disposed within the sliding groove 10 and located below the boss 4. The movable seat 5 cannot rotate within the sliding groove 10. The movable seat 5 has a rectangular block structure. The width of the sliding groove 10 is less than the diagonal length of the end face of the movable seat 5. A limiting member 9 is provided on the top of the movable seat 5. The limiting member 9 has a T-shaped structure and includes a head 901 and a connecting part 902. The connecting part 902 is threadedly connected to the movable seat 5. The head 901 is located on the upper part of the boss 4 and can abut against the boss 4. When the head 901 abuts against the boss 4, the position of the movable seat 5 within the sliding groove 10 is locked. In this specific embodiment, the limiting member 9 is made of bolts, which facilitates manufacturing and operation. When locked in position, the movable seat 5 rises within the sliding groove 10 by rotating the limiting member 9 until it abuts against the boss 4, locking the position of the movable seat 5 through friction.

[0038] like Figure 1As shown, preferably, the lower part of the movable seat 5 is provided with a connecting seat 6, the connecting seat 6 is horizontally provided with a connecting hole, the axis of the connecting hole is perpendicular to the length direction of the fixed rod 3, a bearing is provided in the connecting hole, and the guide part 703 is rotatably provided in the connecting hole through the bearing.

[0039] like Figure 2 As shown, due to the different heights of the electrical components, in order to flexibly adjust the fixed position, this specific embodiment also includes two vertically arranged support rods 2. The two ends of the fixing rod 3 are respectively sleeved on the corresponding support rods 2. The two ends of the fixing rod 3 are provided with through holes. The support rod 2 is also provided with a limit component that can move axially. The limit component can be locked on the support rod 2 and can contact the fixing rod 3. Specifically, in order to facilitate unlocking and locking the position of the limit component, the limit component includes a limit sleeve 8. The limit sleeve 8 is sleeved on the support rod 2. The limit sleeve 8 is divided into two sub-sleeves 11 along its axial center plane. The upper end face of the sub-sleeve 11 can contact the lower end face of the fixing rod 3. The outer circular surface of the sub-sleeve 11 is provided with a connecting end ear 14. The connecting end ear 14 is provided with an internal thread hole. The corresponding connecting end ears 14 of the two sub-sleeves 11 are connected by a connecting bolt 13. After this setting, the limit sleeve 8 can be loosened by simply tightening or loosening the connecting bolt 13, and the adjustment operation is convenient.

[0040] In this specific embodiment, three movable seats 5 are provided.

[0041] The procedure for using this device is as follows:

[0042] First, adjust the height of the fixing rod 3 on the support rod 2 according to the position of the electrical components; rotate the limiting member 9 and move the moving seat 5 so that the moving seat 5 is close to the corresponding electrical equipment; tighten the limiting member 9 to lock the position of the moving seat 5; rotate the wire harness conduit 7 so that the wire harness can be inserted from the guide part 1 702 and then pulled out from the guide part 2 703. Specific Implementation Method Two

[0044] like Figures 3 to 6 As shown, this specific embodiment provides an electrical cabinet, including a cabinet body 1, and also includes a wire harness fixing device according to the first embodiment. Two support rods 2 are arranged opposite to each other inside the cabinet body 1. An electrical mounting rod 18 is also horizontally arranged inside the cabinet body 1, and multiple mounting holes 17 are provided on the electrical mounting rod 18 along its length direction.

[0045] Furthermore, such as Figure 3As shown, mounting plates 16 are vertically installed on two opposing inner walls of the cabinet 1. Multiple mounting holes 17 are provided on the mounting plates 16 along their height direction. A connecting plate 12 is provided at the end of the electrical mounting rod 18. The connecting plate 12 is connected to the mounting plate 16 through the mounting holes 17 at any height. By setting the mounting plates 16, the position of the electrical mounting rod 18 can be adjusted according to the position of the electrical components and the installation space, making it more flexible to use.

[0046] like Figure 5 and Figure 6 As shown, for ease of maintenance, two cabinet doors 20 are provided opposite each other on the cabinet 1.

[0047] In this specific embodiment, three electrical mounting rods 18 and three fixing rods 3 are provided, and the cabinet 1 also includes a top cover.

[0048] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0049] 1. By setting the movable seat 5 and the wire harness conduit 7, the position of the movable seat 5 and the opening orientation of the wire harness conduit 7 can be adjusted according to the position of the wire harness. This avoids the problem that the distribution of the wiring position of the wire harness and the electrical components and the fixed position of the wire harness cannot be set along the natural extension direction of the wire harness. This avoids bending and pulling of the wire harness at the wiring position, avoids stress on the wire harness, and extends the service life of the wire harness.

[0050] 2. By setting a transition bend 701, the wire harness is prevented from bending due to a sharp angle change within the wire harness conduit 7, thereby further extending the service life of the wire harness and facilitating the wire harness to extend from the guide part 703.

[0051] 3. By setting the limiting component 9, the position of the movable base 5 can be locked to prevent the movable base 5 from moving under the action of external force and causing pulling on the wire harness;

[0052] 4. The position of the fixing rod 3 can be adjusted by the support rod 2 and the limiting component to match the height of the electrical components, making it more flexible to use;

[0053] 5. The two-part structure of the limiting sleeve 8 facilitates adjustment and operation;

[0054] 6. By setting the mounting plate 16, the position of the electrical mounting rod 18 can be adjusted according to the position of the electrical components and the installation space, making it more flexible to use;

[0055] 7. The two cabinet doors 20 facilitate internal maintenance.

[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
