Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3The device support insulating column provided by this utility model will now be described. The device support insulating column includes an insulating body 1, a nut 2, and a screw 3. The insulating body 1 includes a hexagonal prism 11 and a cylinder 12 connected in sequence; the outer peripheral wall of the cylinder 12 is provided with a plurality of protrusions 13, which are spaced apart along the axial direction of the insulating body 1, and each protrusion 13 protrudes radially along the insulating body 1; the nut 2 is disposed at one axial end of the insulating body 1; the screw 3 is disposed at the other axial end of the insulating body 1.

[0032] Nut 2 is made of stainless steel or lead-free brass. Its internal thread structure allows it to be connected to the equipment or substrate via an external bolt. Screw 3 is also made of stainless steel or lead-free brass. Its external thread structure allows it to be connected to electrical components on the equipment via the external nut 2. It should be noted that the equipment or substrate typically has external nuts 2 and external bolts; therefore, this device supports the insulation structure and uses a threaded connection with the equipment or substrate, resulting in a simple and versatile connection method.

[0033] The insulating body 1 is made of insulating material and has rigidity. The insulating body 1 includes a hexagonal prism 11 and a cylinder 12. The hexagonal prism 11 is used to enable quick disassembly of the device's supporting insulating column. Since the device's supporting insulating column is connected to the external bolt via a nut 2, the nut 2 can be tightened or loosened by clamping and rotating the hexagonal prism 11 using conventional manufacturing tools, achieving quick disassembly from the external equipment. The cylinder 12 has multiple protrusions 13, each protruding radially outward, increasing the electrical insulation creepage distance on the outer surface of the cylinder 12 to prevent creepage.

[0034] The device's supporting insulating column is molded using injection molding. Specifically, the pre-machined nut 2 and screw 3 are placed into the mold by a robotic arm. Then, the insulating material is injected into a high-precision injection molding machine. After heating and pressurizing, the insulating material is melted and injected into the mold. After cooling and solidification, the basic shape of the device's supporting insulating structure is obtained. Finally, post-processing is performed to remove burrs and flash generated during the molding process, polish the surface to improve its smoothness, clean the surface with a suitable solvent to remove oil and dust, and then dry it.

[0035] This device supports insulating pillars that can be applied in multiple fields. For example, in complex circuit board designs, it serves as support and isolation between components, reducing the risk of short circuits and improving circuit stability. In power equipment, such as transformers and high-voltage switchgear, it is used to isolate conductors of different voltage levels to ensure safe operation of the equipment. In automated production lines and robotic systems, it serves as insulating support for critical components, ensuring that high-precision operation is not subject to electrical interference.

[0036] Compared with the prior art, the device support insulating column provided by this utility model has a six-sided column body 11, which can be quickly assembled and disassembled using conventional manufacturing tools, simplifying the assembly and disassembly operations and improving work efficiency. The cylindrical body 12 of the insulating body 1 is provided with multiple protrusions 13 that protrude radially outward, which can increase the electrical insulation creepage distance, solve the problem of insufficient insulation performance of the device support insulating column, and meet the application requirements in high voltage, high current or complex electromagnetic environments. The device support insulating structure connects two electrical components through nuts 2 and screws 3, which is simple to connect and has strong applicability.

[0037] In some embodiments, the hexagonal prism 11, cylinder 12 and multiple protrusions 13 are integrally formed and made of unsaturated polyester bulk molding compound.

[0038] Bulk (Dough) Molding Compounds (BMC) are characterized by high strength and high insulation properties. They not only have good electrical insulation properties (such as high dielectric strength, high insulation resistance and high tracking index), but also excellent heat resistance, chemical corrosion resistance and mechanical strength. They can maintain stable performance for a long time in harsh working environments and resist the erosion of water, oil and corrosive substances.

[0039] In addition, BMC material has a short molding cycle, making it suitable for manufacturing smaller products, and the products manufactured are dimensionally accurate, making them suitable for mass production.

[0040] In some embodiments, the insulating body 1 may be adopted as follows: Figure 1 , Figure 2 and Figure 3 The structure shown is described in the following document. Figure 1 , Figure 2 and Figure 3 The protrusion 13 has an annular disc-shaped structure; one of the protrusions 13 located on the edge is formed at the junction of the hexagonal prism 11 and the cylinder 12.

[0041] The protrusion 13 has an annular disc structure, thus forming an annular recess between each pair of adjacent protrusions 13. The arrangement of multiple disc-shaped protrusions and recesses increases the creepage distance of the insulating body 1. In addition, the multiple protrusions 13 have an axially stacked structure, which also has the functions of shock absorption and pressure relief, improving the pressure resistance of the insulating body 1.

[0042] To avoid affecting the assembly and disassembly of the device's supporting insulating pillar, multiple protrusions 13 are formed on the cylinder 12. Among them, one protrusion 13 located at the edge is formed at the junction of the hexagonal prism 11 and the cylinder 12. On the one hand, it serves as a transition connection to make the outer surface of the insulating body 1 smooth and prevent bending points. On the other hand, it also increases the strength at the junction of the hexagonal prism 11 and the cylinder 12.

[0043] It should be noted that the radial outer circumference of the protrusion 13, the connection between the protrusion 13 and the hexagonal prism 11, and the connection between the protrusion 13 and the cylinder 12 are all rounded.

[0044] In some embodiments, the insulating body 1 and the nut 2 can be connected by, for example, Figure 1 , Figure 2 and Figure 3 The structure shown is described in the following document. Figure 1 , Figure 2 and Figure 3 The end face of the hexagonal prism 11 is provided with a first mounting groove 14, and the nut 2 is embedded in the first mounting groove 14, and the end face of the nut 2 is flush with the end face of the hexagonal prism 11.

[0045] Nut 2 is embedded in the hexagonal prism 11 and is fixedly connected to the hexagonal prism 11. By using conventional manufacturing tools in the prior art to clamp and rotate the hexagonal prism 11, force can be directly applied to nut 2, which further optimizes the disassembly and assembly operation and avoids the problem of nut 2 slipping.

[0046] The end face of nut 2 is flush with the end face of hexagonal prism 11. Nut 2 does not protrude from hexagonal prism 11. Therefore, nut 2 does not occupy external space, which not only reduces the volume of the device supporting the insulator, but also allows hexagonal prism 11 to provide complete support for nut 2, thereby increasing the fixing strength of nut 2.

[0047] Please see Figure 1 , Figure 2 and Figure 3 Based on the above embodiments, the outer peripheral surface of the nut 2 is provided with a first crimping tooth 21, and the groove wall of the first insert groove 14 is provided with a first tooth groove 141, and the first crimping tooth 21 and the first tooth groove 141 are fitted together.

[0048] Preferably, the first crimping tooth 21 is arranged around the outer peripheral surface of the nut 2, and the first tooth groove 141 is also arranged around the groove wall of the first fitting groove 14. The first crimping tooth 21 can be regarded as a knurling treatment on the surface of the nut 2. The first crimping tooth 21 and the first tooth groove 141 are fitted together to ensure a good connection between the nut 2 and the six-sided prism 11.

[0049] Since the insulating body 1 is injection molded, it can be ensured that the first tooth groove 141 is formed on the groove wall of the first insert groove 14, which perfectly fits the first crimping tooth 21.

[0050] It should be noted that, in order to further improve the connection strength between the nut 2 and the hexagonal prism 11, multiple sets of first crimping teeth 21 can be arranged axially at intervals on the outer surface of the nut 2. Correspondingly, multiple sets of first tooth grooves 141 are arranged axially at intervals on the groove wall of the first insert groove 14.

[0051] In some embodiments, the insulating body 1 and the screw 3 may be connected by a means such as... Figure 1 , Figure 2 and Figure 3 The structure shown is described in the following document. Figure 1 , Figure 2 and Figure 3 The cylinder 12 has a second mounting groove 15 on its end face. The second mounting groove 15 is not connected to the first mounting groove 14. One end of the screw 3 is embedded in the second mounting groove 15, and the other end extends out of the second mounting groove 15.

[0052] The second mounting slot 15 is not connected to the first mounting slot 14, such as Figure 3 As shown, the insulating body 1 can completely insulate and isolate the screw 3 and nut 2, thereby ensuring the insulation and isolation of the two external electrical components, and also preventing creepage from the inside of the insulating body 1.

[0053] One end of the screw 3 is embedded in the second mounting groove 15. Based on the injection molding of the insulating body 1, it is easy to connect the cylinder 12 and the screw 3, and it can also ensure the stable connection between the screw 3 and the insulating body 1.

[0054] In some embodiments, the screw 3 described above can be as follows: Figure 2 The structure shown is described in the following document. Figure 2 The screw 3 includes an inner part 31 and an outer part 32 connected in sequence; the inner part 31 is embedded in the second mounting groove 15, and the outer diameter of the inner part 31 is greater than the outer diameter of the outer part 32 and equal to the outer diameter of the nut 2.

[0055] The inner portion 31 is used to connect with the cylinder 12, and the outer portion 32 is used to form an external thread.

[0056] The outer diameter of nut 2 is equal to the outer diameter of the inner portion 31. That is, the inner diameter of the first insert groove 14 is equal to the inner diameter of the second insert groove 15. This simplifies the mold structure of the injection-molded insulating body 1. An external thread is provided on the extension portion 32. The outer diameter of the extension portion 32 is smaller than the outer diameter of the inner portion 31, so the thread type of the extension portion 32 can be the same as the thread type of nut 2. During use, by observing one end of the insulating body 1, it can be determined whether the device's supporting insulating column is compatible with the electrical components of the equipment.

[0057] Please see Figure 2 and Figure 3 Based on the above embodiments, the outer peripheral surface of the embedded part 31 is provided with a second crimping tooth 311, and the groove wall of the second mounting groove 15 is provided with a second tooth groove 151, and the second crimping tooth 311 and the second tooth groove 151 are fitted together.

[0058] Preferably, the second crimping tooth 311 is disposed around the outer peripheral surface of the inner part 31, and the second tooth groove 151 is also disposed around the groove wall of the second mounting groove 15. The second crimping tooth 311 can be regarded as a knurling treatment on the surface of the inner part 31. The second crimping tooth 311 and the second tooth groove 151 are fitted together to ensure a good connection between the screw 3 and the cylinder 12.

[0059] Since the insulating body 1 is injection molded, it can be ensured that a second tooth groove 151 is formed on the groove wall of the second insert groove 15, which perfectly fits the second crimping tooth 311.

[0060] It should be noted that, in order to further improve the connection strength between the screw 3 and the cylinder 12, multiple sets of second crimping teeth 311 can be arranged axially at intervals on the outer surface of the inner part 31. Correspondingly, multiple sets of second tooth grooves 151 are arranged axially at intervals on the groove wall of the second mounting groove 15.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
