Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fittings, and in particular to a pipe fitting for high altitude applications. Background Technology
[0002] A busbar, also known as a copper busbar or copper conduit busbar, serves as the main conductive channel, enabling efficient transmission of large currents and ensuring the normal operation of the power transmission system. Busbars are mainly used in power systems as high-voltage conductors. The working principle is that in high-voltage and high-current power transmission applications, the busbar transmits power through its internal metal conductors, while the external insulation material ensures safety and efficiency.
[0003] There is currently a Chinese patent application number CN201620783216.4 regarding a connecting terminal ball busbar, comprising a tube body and a ball body. A fitting hole is provided at one end of the ball body, and the end of the tube body is positioned within the fitting hole of the ball body. At least two oblique holes are provided along the circumference of the fitting hole at the open end of the ball body. One end of each oblique hole is located on the outer end face of the ball body, and the other end of each oblique hole communicates with the fitting hole of the ball body. A nut is fixed in each oblique hole, and each nut is threaded with a screw. The end of each screw abuts against the outer wall of the tube body. During on-site installation, the terminal ball is fitted onto the tube body. Because the outer diameter of the tube body is smaller than the inner diameter of the terminal ball, the tube body can be adjusted within the terminal ball to reach the specified length. Then, the terminal ball is fixed to the tube body using screw assemblies within the oblique holes of the terminal ball.
[0004] However, the above-mentioned patent has certain defects in use. Since the main pipe usually needs to be laid over a long distance, it is prone to bending and deformation during transportation and installation due to factors such as climate and terrain in high-altitude areas, which affects the reliability of electrical connections.
[0005] Therefore, a high-altitude pipe fitting is proposed here to solve the aforementioned problems. Utility Model Content
[0006] In order to overcome the shortcomings of existing technologies that are prone to bending and deformation during transportation and installation due to factors such as climate and terrain in high-altitude areas, this utility model provides a high-altitude pipe nut.
[0007] This utility model is achieved using the following technical solution: A high-altitude pipe connector includes a pipe body with contacts at both ends. The pipe body has multiple contacts. One end of each contact has a female connector, and the other end has a sleeve. The sleeve contains a male connector. The bottom of the female connector has a dovetail slider, and the top of the male connector has a dovetail groove that matches the dovetail slider. Multiple pipe bodies are positioned and spliced by sliding the dovetail slider into the dovetail groove. The male connector and the female connector have symmetrically provided first reserved holes, and first positioning pins are provided in the first reserved holes for fixation. The outer wall of the tube body is fitted with an outer layer.
[0008] As a preferred embodiment of this utility model, the dovetail groove is provided with a spring at its end, the spring end is provided with a contact plate, and the contact plate is provided with an elastic washer.
[0009] As a preferred embodiment of the present invention, the outer layer includes a conductor shielding layer, an insulating shielding layer and an outer sheath. The conductor shielding layer is disposed close to the tube body, the insulating shielding layer covers the outside of the conductor shielding layer, and the outer sheath is wrapped around the outside of the insulating shielding layer.
[0010] As a preferred embodiment of this utility model, a protective sleeve is provided at one end of the tube body. The protective sleeve is movably installed on the outer wall of the contact. The protective sleeve, the female connection and the male connection are respectively provided with second reserved holes. A second positioning pin is provided in the second reserved hole for fixing.
[0011] As a preferred embodiment of this utility model, the pipe body is provided with clamps at both ends, and the clamps are fastened to the contact connection.
[0012] As a preferred embodiment of this utility model, the first positioning pin and the second positioning pin are specifically bolts.
[0013] Compared with existing technologies, the advantages of this utility model are: 1. Multiple pipe bodies are quickly positioned and spliced by sliding dovetail sliders into dovetail grooves and fixed by the first positioning pin. This changes the original single-section pipe body into a segmented splicing structure, effectively reducing transportation difficulty and improving installation flexibility. It is especially suitable for construction needs in complex terrain and climate conditions in high-altitude areas. Even if a part of the pipe body is damaged, the damaged section can be replaced individually, greatly reducing maintenance costs.
[0014] 2. In high-altitude areas, the large temperature difference between day and night and the sudden drop in temperature can easily cause the pipe body to expand and contract due to heat. When the temperature drops, the pipe body contracts, and the spring located in the dovetail groove is compressed, which pushes the contact plate and the elastic washer to fit tightly against the joint end face, compensating for the contraction gap and preventing the connection from becoming loose. When the temperature is too high, the pipe body expands, and the spring and the elastic washer are squeezed and rebound, absorbing the axial thrust generated by the expansion, preventing the rigid compression of the pipe body from causing deformation at the splice or cracking of the mortise.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Example: Please see Figures 1-5 A high-altitude pipe fitting includes a pipe body 1 with contacts 11 at both ends. The pipe body 1 has multiple contacts. One end of each contact 11 has a female connector 4, and the other end of each contact 11 has a sleeve 12. The sleeve 12 contains a male connector 3. The female connector 4 has a dovetail slider 41 at its bottom end, and the male connector 3 has a dovetail groove 31 at its top end that matches the dovetail slider 41. Multiple pipe bodies 1 are positioned and spliced by sliding the dovetail slider 41 into the dovetail groove 31. The male connector 3 and the female connector 4 have symmetrically provided first reserved holes 5, and first positioning pins 51 are provided in the first reserved holes 5 for fixing. The outer layer 2 is tightly attached to the outer wall of the tube body 1.
[0018] In this embodiment, the tube body 1 is an integrally formed copper tube with conductivity. The tube body 1 is closely fitted with an outer layer 2, which protects the tube body 1 and provides a shielding effect. The tube body 1 has two contacts 11 at both ends for conductive connection. Specifically, the contacts 11 are used for connection between multiple tube bodies 1 to ensure conductive path. A female connector 4 is provided on one end, and a sleeve 12 is provided on the other end of the contact 11. A female connector 3 is provided inside the sleeve 12. The female connector 4 and the female connector 3 are assembled. Multiple tube bodies 1 are spliced together to form a long conductive structure to adapt to different length requirements in installation scenarios. First reserved holes 5 are symmetrically opened on the female connector 3 and the female connector 4. The female connector 3 and the female connector 4 are fixedly connected by inserting a first positioning pin 51 to ensure the stability of the spliced structure and reliable conductivity.
[0019] Specifically, the dovetail groove 31 is provided with a spring 32 at its end, the spring 32 is provided with a contact plate 321 at its end, and the contact plate 321 is provided with an elastic washer 322.
[0020] In this embodiment, a spring 32 is provided at the end of the dovetail slide 31, and a contact plate 321 is provided at the front end of the spring 32. An elastic washer 322 is provided on the contact plate 321. In high-altitude areas, the temperature difference between day and night is large and the temperature drops suddenly, which can easily cause the pipe body 1 to deform due to thermal expansion and contraction. The spring 32 and the elastic washer 322 on the contact plate 321 work together to effectively absorb the deformation stress caused by temperature changes, and avoid overload damage at the connection between the dovetail slider 41 and the dovetail slide 31, which could lead to deformation at the splice or cracking of the mortise.
[0021] Specifically, the outer layer 2 includes a conductor shielding layer 21, an insulating shielding layer 22, and an outer sheath 23. The conductor shielding layer 21 is set close to the tube body 1, the insulating shielding layer 22 covers the outside of the conductor shielding layer 21, and the outer sheath 23 is wrapped around the outside of the insulating shielding layer 22.
[0022] In this embodiment, specific reference is made. Figure 7 The outer layer 2 mainly serves to protect the tube body 1 from the influence of the external environment. The outer layer 2 includes a conductor shielding layer 21, an insulating shielding layer 22, and an outer sheath 23. From the inside to the outside, the order is tube body 1, conductor shielding layer 21, insulating shielding layer 22, and outer sheath 23. All the above layers are tightly fitted and covered. The conductor shielding layer 21 is used to balance the electric field distribution and reduce partial discharge. The insulating shielding layer 22 further enhances the insulation performance and effectively blocks external electromagnetic interference. The outer sheath 23 mainly protects the internal structure.
[0023] Specifically, a protective sleeve 6 is provided at one end of the tube body 1. The protective sleeve 6 is movably installed on the outer wall of the contact 11. The protective sleeve 6, the sub-connector 3 and the female connection 4 are respectively provided with second reserved holes 62. A second positioning pin 63 is provided in the second reserved hole 62 for fixing.
[0024] In this embodiment, the protective sleeve 6 is a ring structure. When the two pipe bodies 1 are spliced and installed, the protective sleeve 6 covers the connection between the sub-connector 3 and the female connection 4. Two clamps 61 are symmetrically arranged on the protective sleeve 6, which are used to fasten the contact 11 positions at the connection ends of the two pipe bodies 1. The protective sleeve 6, the sub-connector 3 and the female connection 4 are respectively provided with second reserved holes 62. When the protective sleeve 6 is installed at the connection, the second reserved holes 62 on the sub-connector 3 and the female connection 4 are aligned. Adjust the position of the protective sleeve 6 to align the second reserved holes 62 on the protective sleeve 6 with the second reserved holes 62 on the sub-connector 3 and the female connection 4. Then insert the second positioning pin 63 to achieve circumferential fixation and prevent loosening. Tighten the clamps 61 to the outer wall of the contact 11 so that the protective sleeve 6 fits firmly.
[0025] The first positioning pin 51 and the second positioning pin 63 are specifically bolts for easy fixing and disassembly, providing convenience for subsequent maintenance or replacement. The first positioning pin 51 is used for mutual connection and fixing between the pipe bodies 1, and the second positioning pin 63 is used for circumferential locking between the protective sleeve 6 and the connecting end.
[0026] The principle of this utility model is as follows: the original single-section pipe body is changed into segmented pipe body 1 and a splicing structure is formed, which effectively reduces the difficulty of transportation and improves the flexibility of installation. During installation, one of the pipe bodies 1 is fixed first, and the end of the female connector 4 is aligned with the end of the male connector 3 of the other pipe body 1. The dovetail groove 31 on the pipe conductor to be installed is aligned with the dovetail slider 41 on the fixed pipe body 1 and slid in axially. When the dovetail slider 41 is continuously pushed into the dovetail groove 31, the spring 32 is compressed and contracted, and the contact plate 321 moves accordingly. The elastic washer 322 fills the gap in the middle until it is completely fitted and positioned. When the scheduled installation is completed, the male connector 3 is aligned with the first reserved hole 5 on the female connector 4, and the first positioning pin 51 is inserted into the first reserved hole 5 to achieve axial fixation. At this time, the female connector 4 is inserted into the sleeve 12 to complete the installation. Then, the splicing of the pipe body 1 is completed in sequence.
[0027] In high-altitude areas, the large temperature difference between day and night and the sudden drop in temperature can easily cause the pipe body 1 to expand and contract due to heat. When the temperature drops, the pipe body 1 contracts, and the spring 32 located in the dovetail groove 31 is compressed, which pushes the contact plate 321 and the elastic washer 322 to fit tightly against the end face of the sub-connection 3, compensating for the contraction gap and preventing the connection from becoming loose. When the temperature is too high and the pipe body 1 expands, the spring 32 and the elastic washer 322 are squeezed and rebound, absorbing the axial thrust generated by the expansion, preventing the rigid compression of the pipe body 1 from causing deformation at the splice or cracking of the mortise. After all the pipe bodies 1 are spliced, the second reserved holes 62 on the sub-connection 3 and the female connection 4 are aligned. The protective sleeve 6 is put on the outside of the two connection points. The position of the protective sleeve 6 is adjusted so that the second reserved hole 62 on the protective sleeve 6 is aligned with the second reserved hole 62 on the sub-connection 3 and the female connection 4. Then the second positioning pin 63 is inserted to achieve circumferential fixation and prevent loosening.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
