[0002] With the continuous development of the power equipment industry, the requirements for power density are also increasing, resulting in highly compact cabinet space. Large cross-section cables need to meet the minimum turning radius (≥8D, where D is the cable diameter) requirement of the IEC (International Electrotechnical Commission) standard, which creates a sharp contradiction with traditional wiring methods. Fixed clamps cannot dynamically adapt to narrow spaces, and forced bending causes the risk of insulation damage. On the other hand, the method of using braided tape binding is not secure and its reliability decreases over time. Utility Model Content
[0003] The technical problems to be solved by this utility model are such as unreliable fixing and large wiring space requirements. The purpose is to provide a large-diameter cable turning clamping device to solve the above problems.
[0004] This utility model is achieved through the following technical solution:

[0006] The guide members are provided with at least two and are rotatably mounted on the base respectively, and a cable passage groove is formed between two adjacent guide members; accordingly, the angle of the cable passage groove is adjusted by rotating the guide members to adjust the cable passage path.
[0007] The base and end cap are positioned opposite each other to form a fixing groove for fixing the cable, and correspondingly, the guide is located between the base and the end cap.
[0008] In one possible design, the base is provided with fixing holes and modular holes. The fixing holes are used to connect the base to other components, and the modular holes are used to connect guide components.
[0009] The modular holes are provided in a number and spaced apart on the base. The guide is connected to one of the modular holes to adjust the width of the wire threading groove.
[0010] In one possible design, the base is made of SMC material and has beveled edges on the sides.
[0011] In one possible design, the guide is constructed as a strip made of SMC material, with chamfered edges on the vertical sides.
[0012] In one possible design, the base has a detachable connecting rod on its modular hole. The connecting rod is used to connect the guide and the end cap. Correspondingly, the guide has a matching connecting hole, and the end cap has a matching secondary modular hole.
[0013] In one possible design, the end cap is made of SMC material, the length of the end cap is less than the length of the base, and the sub-module holes on the end cap are set to correspond one-to-one with the module holes on the base.
[0014] In one possible design, the height of the guide is less than the diameter of the cable and less than the length of the connecting rod.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0027] like Figures 1-4 As shown, a large-diameter cable turning and clamping device includes a base 1, a guide 2, and an end cap 3;
[0028] At least two guide members 2 are provided and rotatably mounted on the base 1 respectively, and a cable passage groove is formed between two adjacent guide members 2; accordingly, the angle of the cable passage groove is adjusted by rotating the guide members 2 to adjust the cable passage path.
[0029] The base 1 and the end cover 3 are arranged opposite each other to form a fixing groove for fixing the cable. Correspondingly, the guide 2 is located between the base 1 and the cover plate.
[0030] The base 1 is used to connect other components, which not only fixes the large-diameter cable turning and clamping device, but also allows the large-diameter cable turning and clamping device to be set in the side wall of the cabinet, so that the layout of the large-diameter cable turning and clamping device is more flexible.
[0031] The guide 2 is used to guide the cable path so that the cable can be guided to the target connection point in the most comfortable way. At the same time, in a confined space, the angle of the cable tray can be adjusted by rotating the guide 2 to guide the cable to any angle, which greatly reduces the space required by the cable. This enables cable installation in confined spaces, so that the cable can meet the turning radius required by the national standard for cables and avoid damage to the cable insulation layer caused by forced bending.
[0032] The end cap 3 and the base 1 cooperate to form a fixing groove and fix the cable, firmly securing the cable to the large-diameter cable turning clamping device, which helps reduce accidental disturbance to the cable during operation. At the same time, the base 1 connects to other components, making the fixing of the large-diameter cable turning clamping device more reliable, which helps increase the reliability of the cable during long-term use.
[0033] During operation, a reasonable cable laying route is designed based on the actual layout space and cable diameter; based on the planned route, the rotation angle of the guide 2 is determined so that the cable trough is adapted to the cable laying route.
[0034] During installation, depending on the actual situation, there are three possible installation methods: First, install the cable on the large-diameter cable turning and clamping device, and then connect other components via the base 1; second, install the large-diameter cable turning and clamping device on other components, and then thread the cable through it; third, install the base 1 and guide 2 of the large-diameter cable turning and clamping device on other components, thread the cable through it, and finally secure it via the end cap 3. The operator can choose the method that best suits their needs.
[0035] It is worth noting that the base 1 is provided with at least two guide members 2, and a wire-passing groove is formed between two adjacent guide members 2. In other words, at least one cable can be installed on the large-diameter cable turning and clamping device. Based on this, the operator selects the number of guide members 2 according to the actual situation, thereby determining the number of cables.
[0036] In one possible implementation, the base 1 is provided with a fixing hole 101 and a modular hole 102. The fixing hole 101 is used to connect the base 1 to other components, and the modular hole 102 is used to connect the guide 2.
[0037] A number of modular holes 102 are provided and spaced apart on the base 1. The guide 2 is connected to one of the modular holes 102 to adjust the width of the wire threading groove.
[0038] Based on the above design, the base 1 is connected to other components through fixing holes 101. Preferably, at least two fixing holes 101 are provided to effectively increase the number of connection points while achieving force balance, thereby improving the reliability and stability of the connection. Modular holes 102 are used to connect guide members 2. It is easy to understand that the spacing between two adjacent guide members 2 depends on the installed cable. Since there are various cable types, multiple modular holes 102 are provided and spaced apart to facilitate adjustment of the guide member 2's position according to the actual cable type.
[0039] Optionally, the multiple modular holes 102 are divided into two groups and symmetrically arranged on the base 1, and two guide members 2 are provided and respectively installed on one group of modular holes 102. Based on this, the minimum distance between the two groups of modular holes 102 is the minimum diameter of the cable that can be installed. If the diameter of the cable increases, the two guide members 2 can be moved synchronously towards the end of the base 1. Furthermore, this scheme is preferred for the case of installing only one cable.
[0040] Optionally, multiple modular holes 102 are evenly distributed along the length of the base 1, and at least two guide members 2 are disposed on the base 1. Based on this, the number of guide members 2 is determined according to the number of cables, and the distance between two adjacent guide members 2 is determined according to the diameter of the cables.
[0041] In one possible implementation, the base 1 is made of SMC material, and the sides of the base 1 are beveled. Based on this, SMC (Sheet Molding Compound) is a thermosetting composite material with a smooth surface finish, which, combined with the beveled design, prevents damage to the cable insulation layer during the clamping and fixing of the cable.
[0042] In one possible implementation, guide 2 is constructed as a strip made of SMC material, with chamfered edges on its vertical sides. Based on the above design, guide 2 is also made of SMC material to protect the cable's insulation layer. The strip structure is simple and easy to process, helping to reduce economic costs. The chamfered edges on the vertical sides eliminate stress concentration and prevent damage to the cable's insulation layer.
[0043] Regarding the connection between the base 1 and the guide 2, a practical and feasible solution is given here. Specifically, in one possible implementation, the base 1 is provided with a detachable connecting rod 4 on the modular hole 102. The connecting rod 4 is used to connect the guide 2 and the end cap 3. Correspondingly, the guide 2 is provided with a matching connecting hole 201, and the end cap 3 is provided with a matching secondary modular hole 301.
[0044] Based on the above design, the connecting rod 4 extends out of the base 1 and beyond it. The guide 2 is sleeved on the connecting rod 4 and can rotate relative to the connecting rod 4, thereby adjusting the angle of the guide 2. Simultaneously, the length of the connecting rod 4 is further extended to connect to the end cap 3, thus simplifying the structure and reducing operational difficulty.
[0045] In one possible implementation, the end cap 3 is made of SMC material, and its length is less than that of the base 1. The sub-module holes 301 on the end cap 3 correspond one-to-one with the module holes 102 on the base 1. Based on this design, the end cap 3 is also made of SMC material to protect the cable insulation layer. Since the end cap 3 and the base 1 are connected by a connecting rod 4, the sub-module holes 301 should correspond to the module holes 102 to allow the connecting rod 4 to align and pass through, thus connecting the base 1 and the end cap 3. Furthermore, the length of the end cap 3 is less than that of the base 1 to expose the fixing holes 101 on the base 1, avoiding obstruction and improving the ease of connection of the base 1.
[0046] In one possible implementation, the height of the guide 2 is less than the diameter of the cable and less than the length of the connecting rod 4. Based on the above design, the height of the guide 2 is less than the diameter of the cable, ensuring that the end of the cable extends beyond the guide 2, allowing the end cap 3 to contact and press against the cable. The end cap 3 then mates with the base 1 to secure the cable. Furthermore, the base 1 and the end cap 3 are connected by the connecting rod 4, meaning the diameter of the cable is less than the length of the connecting rod 4. This ensures that the length of the connecting rod 4 has sufficient slack, allowing for connection while accommodating cables of different diameters.
[0047] In one possible implementation, the connecting hole 201 of the guide member 2 is constructed as a threaded hole, and correspondingly, the connecting rod 4 is provided with a matching external thread. Based on this, the connection between the base 1 and the guide member 2 is achieved through a threaded connection, realizing a reliable connection while retaining the ability to rotate, so as to avoid the separation of the base 1 and the guide member 2 and avoid loss due to the disassembly of parts.
[0048] In one possible implementation, the connecting rod 4 is provided with a suitable fastener 5, which is sleeved on the connecting rod 4 and abuts against the end cap 3.
[0049] Based on the above design, the fixing component 5 serves two purposes: firstly, it connects the base 1, guide 2, and end cap 3 into a cohesive whole; secondly, it applies pressure to the cable through the fixing component 5, thereby securing the cable. Specifically, the fixing component 5 includes a flat washer 501, a spring washer 502, and a nut 503 stacked sequentially, and the connecting rod 4 is a bolt. During fixing, the operator simply rotates the nut 503 to firmly secure the cable.
[0050] Alternatively, a bearing can be installed within the modular hole 102, and the guide member 2 can be inserted into the bearing via an extended shaft, thereby connecting the base 1 and the guide member 2 through the bearing and ensuring the rotation of the guide member 2 relative to the base 1. The base 1 and the end cover 3 are connected by bolts and nuts 503. While achieving the same function, this method involves more components and is less economical compared to connecting the base 1, guide member 2, and end cover 3 simultaneously via a connecting rod 4.
[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
