[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-4 As shown, this utility model discloses an integrated wire fixing device, comprising: Fastening assembly 1, the fastening assembly 1 includes a fixed base 11, a clamping block 12 and a locking mechanism, one side of the clamping block 12 is hinged to the fixed base 11, and the locking mechanism is disposed between the clamping block 12 and the fixed base 11; The support assembly 2 includes a support rod 21 and an insulating sleeve 22. One end of the support rod 21 is connected to the fixed base 11, and the other end of the support rod 21 is provided with a connector 24. A fixing nut 25 is provided at the end of the connector 24 away from the support rod 21. The insulating sleeve 22 is sleeved on the outside of the support rod 21 and the connector 24. Multiple insulating baffles 23 are provided on the surface of the insulating sleeve 22 along the axial direction. The multiple insulating baffles 23 are integrally formed with the insulating sleeve 22.

[0019] In this invention, the fastening component 1 is used to clamp and fix the wire harness. Specifically, one side of the clamping block 12 is hinged to the fixing seat 11, allowing the clamping block 12 to flip. In actual operation, the cable is placed against the fixing seat 11, then the clamping block 12 is fastened onto the cable, and then the cable is fixed between the clamping block 12 and the fixing seat 11 by a locking mechanism. One end of the support rod 21 is connected to the fixing seat 11, and the other end is fixed by a connector 24, specifically by a locking nut 14. An insulating sleeve 22 is sleeved on the outside of the connecting rod, and multiple insulating baffles 23 are provided on the surface of the insulating sleeve 22, and the multiple insulating baffles 23 are integrally formed with the insulating sleeve 22. The insulating baffles 23 can isolate the high-voltage conductor from the grounding component, control the electric field, and the multiple insulating baffles 23 can also effectively reduce the risk of flashover.

[0020] This utility model realizes an integrated structure of wire fastener and insulator. The support rod 21 is connected to the bottom of the fixed base 11 to provide the necessary support force, while the insulating sleeve 22 and multiple insulating baffles 23 are integrally formed and sleeved on the outside of the support rod 21. This integrated structure not only simplifies the installation process and reduces installation nodes, but also greatly improves the overall stability and durability of the device.

[0021] Furthermore, the locking mechanism includes a locking screw 13 and a locking nut 14. One end of the locking screw 13 is hinged to the fixed seat 11, and the other end of the locking screw 13 passes through the pressing block 12. The locking nut 14 is sleeved on the end of the locking screw 13 away from the fixed seat 11, and the locking nut 14 abuts against the pressing block 12.

[0022] Specifically, one end of the locking screw 13 is hinged to the fixed seat 11 and can rotate around the hinge point; the other end of the locking screw 13 passes through the clamping block 12, and the clamping block 12 can be connected to the fixed seat 11 by adjusting the locking nut 14.

[0023] Furthermore, a washer 17 is provided between the locking nut 14 and the clamping block 12, and the washer 17 is sleeved on the outside of the locking screw 13.

[0024] Specifically, during actual installation, the locking nut 14 directly contacts the washer 17, which can prevent the locking nut 14 from wearing down the surface of the clamping block 12 during adjustment and extend the service life of the entire device.

[0025] Furthermore, the clamping block 12 is provided with a bayonet 122 that cooperates with the locking screw 13, and the port of the bayonet 122 is provided with a limiting platform 123.

[0026] Specifically, the design of the bayonet 122 facilitates the connection between the locking screw 13 and the clamping block 12. During actual installation, the locking screw 13 is inserted into the bayonet 122, and then the locking nut 14 is tightened. The width of the bayonet 122 is equal to the diameter of the locking screw 13. The diameter of the locking nut 14, which is fitted outside the locking screw 13, is larger than the width of the bayonet 122. The limiting platform 123 at the end of the bayonet 122 can limit the locking nut 14, preventing the locking screw 13 from falling out of the bayonet 122.

[0027] Furthermore, the outer side of the fixing base 11 is covered by a first insulating shell 111, and the outer side of the clamping block 12 is covered by a second insulating shell 121. A protective cover 15 is hinged to the top of the second insulating shell 121, and the protective cover 15 is fastened to the bayonet 122.

[0028] Specifically, the first insulating shell 111 and the second insulating shell 121 not only provide additional protection for the fixing base 11 and the clamping block 12, extending the number of uses and service life of the clamping block and the fixing base 11, but also enhance the structural strength of the entire device. Secondly, the protective cover 15 located on the top of the second insulating shell 121 can be fastened to the port of the bayonet 122, protecting the locking nut 14 and preventing it from rusting and corroding, which would affect subsequent disassembly and replacement.

[0029] As a preferred embodiment of this invention, the first insulating shell 111, the second insulating shell 121, the protective cover 15, the insulating sleeve 22, and the insulating baffle 23 are all made of epoxy resin composite material. This choice is based on the many excellent properties of epoxy resin composite material, which significantly improves the device's structural strength, corrosion resistance, insulation performance, and service life. Epoxy resin composite material is a high-performance thermosetting resin material with characteristics such as high strength, lightweight, excellent corrosion resistance, good processing performance, and high stability.

[0030] Furthermore, an anti-slip block 16 is provided between the clamping block 12 and the fixing seat 11.

[0031] Specifically, the anti-slip block 16 not only increases the friction of the contact surface, effectively preventing the cable from slipping or falling off during clamping, but also improves the user's feel during operation, making the entire clamping process smoother and more controllable.

[0032] As a preferred embodiment of this utility model, the size of the insulating sleeve 22 near the two insulating baffles 23 is larger than the size of the middle insulating baffle 23. In actual installation, the entire insulating sleeve 22 is installed vertically. The insulating baffle 23 near the fixing base 11 is at the top and has the largest size; the one near the connector 24 is at the bottom and has the second largest size; the insulating baffle 23 in the middle area has the smallest size. When directly exposed to dirt and harsh weather conditions in the external environment, the larger top insulating baffle 23 can effectively intercept and disperse most of the dirt, while the bottom insulating baffle 23 can also block and filter some of the dirt, thus preventing contamination of the inner insulating baffle 23 and improving the anti-flashover effect of the insulating baffle 23.

[0033] Furthermore, the surfaces of the insulating sleeve 22 and the insulating baffle 23 are provided with an anti-flashover coating.

[0034] Specifically, the anti-flashover coating is a silicone rubber anti-flashover coating with a double-layer structure. The bottom layer is an adhesive layer containing a coupling agent, whose main function is to ensure a strong bond between the coating and the insulating baffle 23. KH-550 silane coupling agent is selected as the key component in this adhesive layer. This coupling agent has excellent adhesion and chemical stability, effectively enhancing the adhesion between the coating and the insulating baffle 23 and preventing the coating from peeling off or cracking during use. Above the adhesive layer is a hydrophobic silicone rubber outer layer, made of methyl vinyl silicone rubber. Methyl vinyl silicone rubber is renowned for its excellent hydrophobicity, weather resistance, and electrical insulation properties, making it an ideal material for manufacturing high-performance anti-flashover coatings. This outer layer not only effectively prevents moisture and dirt from penetrating into the coating, but also forms a non-conductive insulating layer when dirt adheres, thus significantly reducing the risk of flashover.

[0035] Furthermore, the thickness of the anti-flashover coating is 0.5mm-2mm.

[0036] Specifically, the thickness of the anti-flashover coating is precisely controlled within the range of 0.5 mm to 2 mm. This thickness selection is based on a comprehensive consideration of the coating's protective effect, durability, and cost-effectiveness. A coating that is too thin may not provide sufficient protection, while a coating that is too thick may increase costs and potentially affect the overall performance of the device.

[0037] Furthermore, the insulating baffle 23 is disc-shaped. This shape not only helps reduce wind resistance and mitigate the impact on the device under adverse weather conditions, but also provides uniform force dispersion when subjected to external impacts, enhancing the device's impact resistance.

[0038] In summary, this utility model introduces an integrated wire fixing device. This utility model achieves an integrated structure of the wire fixing device and the insulator. The support rod 21 is connected to the bottom of the fixing base 11, providing necessary support force. The insulating sleeve 22 and multiple insulating baffles 23 are integrally formed and fitted onto the outside of the support rod 21. This integrated structure not only simplifies the installation process and reduces installation nodes, but also greatly improves the overall stability and durability of the device. Secondly, the surface of the insulating baffles 23 is provided with an anti-flashover coating, forming a unique flashover protection mechanism for the device. The insulating baffles 23 are made of silicone rubber, which has good pollution resistance and water repellency, effectively preventing the accumulation of dirt. Even if dirt adheres, it is difficult to form a conductive channel, thus significantly reducing the risk of flashover.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
