Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy conductors, and more specifically, to a heat-resistant aluminum alloy conductor with an aluminum clad steel core. Background Technology

[0002] In the field of power transmission, aluminum-clad steel-core heat-resistant aluminum alloy conductors have been widely used due to their excellent conductivity, heat resistance, and mechanical properties.

[0003] The connection process for this type of conductor is cumbersome, making quick and easy connections difficult and significantly reducing construction efficiency. More importantly, poor connections can easily generate excessive heat at the joint. This not only increases energy loss but can also pose safety hazards. Furthermore, aluminum-clad steel core heat-resistant aluminum alloy conductors expand due to heat during operation and contract upon cooling. Conventional connectors lack the ability to adjust the tightening force according to the conductor's expansion and contraction.

[0004] During long-term expansion and contraction cycles, the connection between the conductor and the connector gradually loosens, leading to increased contact resistance, further exacerbating the heating problem, creating a vicious cycle that seriously affects the service life of the conductor and the stability of power transmission. How to invent a heat-resistant aluminum alloy conductor with an aluminum-clad steel core to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aluminum-clad steel core heat-resistant aluminum alloy conductor, which aims to improve the problem that aluminum-clad steel core heat-resistant aluminum alloy conductors expand due to heat during operation and contract after cooling. Conventional connectors lack the ability to adjust the locking force according to the expansion and contraction of the conductor.

[0006] This utility model is achieved as follows: an aluminum-clad steel core heat-resistant aluminum alloy conductor, comprising...

[0007] Aluminum-clad steel core heat-resistant aluminum alloy conductor body;

[0008] A quick-connect mechanism is located at the connection point of the two aluminum-clad steel core heat-resistant aluminum alloy wire bodies.

[0009] The quick connection mechanism includes a limiting component, which includes a limiting shell. An upper limiting block and a lower limiting block are respectively provided on the upper and lower sides of the limiting shell for limiting and sliding. The terminals of the aluminum-clad steel core heat-resistant aluminum alloy wire body are respectively located between the upper limiting block, the lower limiting block and the limiting shell.

[0010] The limiting component is equipped with elastic locking components at both ends, and the elastic locking components elastically abut against the back of the upper limiting block and the lower limiting block, respectively.

[0011] In a preferred embodiment of this utility model, the limiting component further includes a guide block, which is fixedly installed inside the limiting shell, and the upper limiting block and the lower limiting block are respectively slidably disposed on the upper and lower sides of the guide block.

[0012] In a preferred embodiment of this utility model, the limiting shell is a rounded rectangle with hollow ends, and the guide block is inclinedly disposed inside the limiting shell.

[0013] In a preferred embodiment of this utility model, both the upper limit block and the lower limit block are right-angled trapezoids, and the inclined surfaces of the upper limit block and the lower limit block are respectively connected to the guide block for limiting and sliding.

[0014] In a preferred embodiment of this utility model, the upper limit block and the lower limit block respectively have limit grooves on the side near the upper and lower inner walls of the limit shell. The limit grooves are equally divided with oblique stripe patterns, and the oblique stripe patterns are at 45° to the axial direction of the aluminum-clad steel core heat-resistant aluminum alloy conductor body.

[0015] In a preferred embodiment of this utility model, guide rails are fixedly connected to both sides of the guide block, and mating rails are respectively provided on the side of the upper limit block and the lower limit block that are in contact with the guide block. The mating rails are slidably connected to the guide rails.

[0016] In a preferred embodiment of this utility model, the elastic locking assembly includes an outer frame, which is fixedly connected to both ends of the limiting shell. A threaded rod is threaded through the back of the outer frame, and the threaded rod abuts against the ends of the upper limit block and the lower limit block respectively.

[0017] In a preferred embodiment of this utility model, the outer frame is U-shaped, and both ends of the outer frame are fixedly connected to the two ends of the limiting shell. Arc-shaped grooves are provided on the upper and lower sides of the outer frame, and a screw handle is fixedly connected to one end of the threaded rod located outside the outer frame.

[0018] In a preferred embodiment of this utility model, an adjusting ring is threaded onto the outer thread of the threaded rod, a rotating ring is rotatably mounted on one side of the adjusting ring, a spring is fixedly sleeved onto the outer side of the rotating ring, and the ends of the spring abut against the ends of the upper limit block and the lower limit block, respectively.

[0019] In a preferred embodiment of this utility model, the spring is a progressive spring.

[0020] The beneficial effects of this utility model are as follows: The aluminum-clad steel core heat-resistant aluminum alloy conductor obtained by the above design allows the progressive spring in the elastic locking assembly to automatically adjust the locking force on the conductor according to its expansion and contraction. When the conductor heats up and expands, the spring is compressed, and the upper and lower limit blocks move backward to provide expansion space for the conductor. When the conductor cools and contracts, the spring rebounds, pushing the upper and lower limit blocks to re-lock the conductor, ensuring a stable connection at all times and effectively avoiding loosening caused by thermal expansion and contraction.

[0021] The limiting grooves and internal diagonal stripes on the upper and lower limit blocks fit tightly against the surface of the wire, increasing friction and preventing the wire from slipping at the connection point. Meanwhile, the guide blocks, guide rails, and mating rails ensure the stability of the upper and lower limit blocks during movement, further improving the stability of the connection.

[0022] The threaded rod and adjusting ring in the elastic locking assembly can adjust the initial spring force according to actual needs to accommodate aluminum-clad steel core heat-resistant aluminum alloy wires of different specifications and operating environments, thus enhancing the versatility and adaptability of the connection mechanism.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an aluminum-clad steel core heat-resistant aluminum alloy conductor, comprising...

[0031] Aluminum-clad steel-core heat-resistant aluminum alloy conductor body 100; quick-connect mechanism 200, located at the connection point of two aluminum-clad steel-core heat-resistant aluminum alloy conductor bodies 100; quick-connect mechanism 200 includes a limiting component 210, the limiting component 210 includes a limiting shell 211, the upper and lower sides of the limiting shell 211 are respectively provided with an upper limiting block 213 and a lower limiting block 214 for limiting sliding, and the terminals of the aluminum-clad steel-core heat-resistant aluminum alloy conductor bodies 100 are respectively located at the upper limiting block 213 and the lower limiting block 214. Between block 214 and limiting shell 211; elastic locking components 220 are respectively installed at both ends of limiting component 210. The elastic locking components 220 elastically abut against the back of upper limit block 213 and lower limit block 214 respectively. The elastic abutment of the elastic locking components 220 is used to reduce the excessive compression of limiting component 210 caused by the heat expansion of aluminum-clad steel core heat-resistant aluminum alloy wire body 100 during operation, which may easily lead to damage to limiting component 210 and affect the connection to aluminum-clad steel core heat-resistant aluminum alloy wire body 100.

[0032] Please see Figure 2 and Figure 3The limiting component 210 also includes a guide block 212, which is fixedly installed inside the limiting shell 211. An upper limiting block 213 and a lower limiting block 214 are respectively slidably disposed on the upper and lower sides of the guide block 212. The limiting shell 211 is a rounded rectangle with hollow ends, and the guide block 212 is inclinedly disposed inside the limiting shell 211. Both the upper limit block 213 and the lower limit block 214 are right-angled trapezoids. The inclined surfaces of the upper limit block 213 and the lower limit block 214 are respectively connected to the guide block 212 for limiting and sliding. The right-angled surfaces of the upper limit block 213 and the lower limit block 214 abut against the aluminum-clad steel core heat-resistant aluminum alloy conductor body 100. When the aluminum-clad steel core heat-resistant aluminum alloy conductor body 100 is pulled outward, the aluminum-clad steel core heat-resistant aluminum alloy conductor body 100 will drive the upper limit block 213 and the lower limit block 214 to move outward. At this time, because the guide block 212 is inclined, the upper limit block 213 and the lower limit block 214 will continuously squeeze the aluminum-clad steel core heat-resistant aluminum alloy conductor body 100 when the upper limit block 213 and the lower limit block 214 move, thus locking it.

[0033] Limiting grooves 216 are respectively formed on the upper and lower inner walls of the limiting shell 211 near the upper and lower inner walls of the upper limit block 213 and the lower limit block 214. The limiting grooves 216 are equally divided with oblique strip patterns. The oblique strip patterns are at 45° to the axial direction of the aluminum-clad steel core heat-resistant aluminum alloy wire body 100. Correspondingly, wire grooves 218 are formed on the upper and lower inner walls of the limiting shell 211. The wire grooves 218 are used to place the wire in conjunction with the limiting grooves 216. The oblique strip patterns in the limiting grooves 216 are used to increase the friction with the wire. The oblique strip patterns can adapt to the expansion of the wire to a certain extent, provide a reasonable direction of movement for the trapezoidal block, and generate appropriate friction and component forces during the expansion and contraction of the wire, so as to ensure the stable clamping and pressure control of the wire by the trapezoidal block.

[0034] Guide rails 215 are fixedly connected to both sides of the guide block 212. The upper limit block 213 and the lower limit block 214 are respectively provided with mating rails 217 on the side that is in contact with the guide block 212. The mating rails 217 are slidably connected to the guide rails 215. The guide rails 215 are used to make the upper limit block 213 and the lower limit block 214 move stably.

[0035] Please see Figure 3 and Figure 4The elastic locking assembly 220 includes an outer frame 221, which is fixedly connected to both ends of the limiting shell 211. A threaded rod 222 is threaded through the back of the outer frame 221, and the threaded rod 222 abuts against the ends of the upper limiting block 213 and the lower limiting block 214, respectively. The outer frame 221 is U-shaped, with both ends fixedly connected to the ends of the limiting shell 211. Arc-shaped grooves are provided on the upper and lower sides of the outer frame 221. A screw handle 223 is fixedly connected to one end of the threaded rod 222 outside the outer frame 221. The arc-shaped grooves prevent friction with the wires, and the screw handle 223 facilitates the screwing of the threaded rod 222.

[0036] An adjusting ring 224 is threaded onto the external thread of the threaded rod 222. A rotating ring 225 is rotatably mounted on one side of the adjusting ring 224. A spring 226 is fixedly fitted onto the outside of the rotating ring 225. The ends of the spring 226 abut against the ends of the upper limit block 213 and the lower limit block 214, respectively. The adjusting ring 224 is a nut or a regular polygon, which is convenient to tighten with a wrench. Tightening the adjusting ring 224 is used to adjust the initial abutment force of the spring 226 against the upper limit block 213 and the lower limit block 214 to prevent the upper limit block 213 and the lower limit block 214 from shifting arbitrarily. The spring 226 is a progressive spring, which is used to ensure that the aluminum-clad steel core heat-resistant aluminum alloy wire body 100 can only compress the spring 226 when a large expansion force is generated, thus preventing the spring 226 from being compressed arbitrarily.

[0037] Working principle: When connecting two aluminum-clad steel-core heat-resistant aluminum alloy wire bodies 100, insert the wire terminals into the limiting shell 211 respectively, positioned between the upper limiting block 213, the lower limiting block 214, and the limiting shell 211. By turning the screw handle 223 at the end of the threaded rod 222, the threaded rod 222 moves into the limiting shell 211, pushing the upper limiting block 213 and the lower limiting block 214 along the guide rail 215 of the guide block 212 towards the wire, until the wire is clamped.

[0038] During adjustment, the initial compression of the spring 226 can be adjusted by rotating the adjusting ring 224, thereby changing the initial locking force of the spring 226 on the conductor. When the aluminum-clad steel core heat-resistant aluminum alloy conductor body 100 heats up and expands during operation, the conductor will squeeze the upper limit block 213 and the lower limit block 214, causing them to overcome the elastic force of the spring 226 and move backward along the guide rail 215, providing space for the expansion of the conductor.

[0039] At this point, spring 226 is further compressed. When the conductor cools and contracts, spring 226 rebounds, pushing upper limit block 213 and lower limit block 214 back towards the conductor, locking the conductor again and ensuring that upper limit block 213 and lower limit block 214 maintain stable pressure on the conductor, thus ensuring the reliability of the connection. The oblique stripe pattern in the upper limit groove 216 of upper limit block 213 and lower limit block 214 is in close contact with the surface of the conductor, increasing friction, preventing conductor slippage, and ensuring the stability of the connection.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
