Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a power insulated winding terminal. Background Technology

[0002] During power line installation, utility poles are used to support the power lines, preventing them from sagging due to excessive length and thus preventing breakage. When the power lines are supported by the poles, electrical insulated winding terminals are used to wrap the power lines to maintain their tension.

[0003] Most existing electrical insulation winding terminals are made of ceramic. When working at heights, ceramic electrical insulation winding terminals are large in size and are easily damaged when they collide with metal tools during installation. This requires scrapping the entire electrical insulation winding terminal, which not only wastes resources and increases the maintenance cost of the power system, but is also inconvenient to carry and affects the climbing speed of power personnel. Therefore, we propose an electrical insulation winding terminal. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an electrically insulated winding terminal.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An electrically insulated wire-wound terminal, comprising:

[0007] The base has a plurality of winding terminal bodies on its top, and one of the winding terminal bodies has a cable management post on its top for limiting the wire.

[0008] Multiple plug-in devices are provided inside the multiple winding terminal bodies. A self-locking component is provided between the base and the lowest winding terminal body. Multiple fixing devices are provided at the bottom of the multiple plug-in devices to fix them. Through the cooperation of the multiple plug-in devices and the multiple fixing devices, the multiple winding terminal bodies are locked and fixed, so that the multiple winding terminal bodies are stacked.

[0009] The plug-in device includes a first plug platform disposed inside the winding terminal body. A connecting rod is fixed to the bottom of the first plug platform, and a support column is fixed to the bottom of the connecting rod. A second plug platform that can be raised and lowered is provided on the lower half of the connecting rod. Two detachable locking rods are symmetrically arranged on the outer wall of the support column. Both the first plug platform and the second plug platform are configured as flat-topped conical shapes. The wider ends of the first plug platform and the second plug platform are located on the same side. The wider end of the second plug platform is also provided with an arc-shaped chamfer. A trapezoidal groove is opened at the bottom of the second plug platform. The top of the connecting rod is fixed to the top of the groove.

[0010] The fixing device includes a locking sleeve located at the bottom of the support column. The middle of the locking sleeve is recessed inward to form a cavity that fits the support column. A collar is fixed to the lower half of the locking sleeve. Two retractable locking blocks are provided inside the collar. Both locking blocks have inclined surfaces on their opposing sides. Multiple observation slots are provided on the outer wall of the locking sleeve to facilitate observation of the internal condition of the locking sleeve. After the collar inside one of the two stacked winding terminal bodies is placed on top of the other first insertion platform, the collar moves the two locking blocks. The inclined surfaces of the two locking blocks move along the outer wall of the first insertion platform, moving the locking blocks between the first and second insertion platforms. The opposing sides of the two locking blocks contact the outer wall of the connecting rod, thereby limiting the first insertion platform and fixing the multiple winding terminal bodies.

[0011] As a preferred embodiment of the present invention, two baffles are fixed on opposite sides of the two locking blocks. A telescopic column is fixed to the end of the two baffles away from the locking blocks. The end of the telescopic column away from the locking blocks passes through the locking sleeve and is inserted into the inside of the collar. The inner wall of the collar has a telescopic groove adapted to the telescopic column. A second spring is provided inside the telescopic groove. The free end of the second spring is fixed to the end of the telescopic column away from the locking blocks. By compressing the second spring, the locking blocks can move quickly along the outer wall of the first insertion platform. When the locking blocks move to the bottom of the first insertion platform, the second spring releases its elastic force to push the telescopic column to move, so that the telescopic column pushes the locking blocks to move between the first insertion platform and the second insertion platform through the baffles.

[0012] As a preferred embodiment of the present invention, two fixing plates are symmetrically fixed to the upper half of the outer wall of the locking sleeve. Each fixing plate has a liftable positioning rod at its end away from the locking sleeve. Two load-bearing plates are symmetrically fixed to the inner wall of the winding terminal body. Each load-bearing plate has a mounting hole adapted to the positioning rod at its end away from the winding terminal body. A first spring is fixed to the bottom of each fixing plate. The free end of the first spring contacts the top of the load-bearing plate. The positioning rod is inserted into the mounting hole, allowing the load-bearing plate to limit the positioning rod, the positioning rod to limit the fixing plate, the fixing plate to limit the locking sleeve, the locking sleeve to limit the collar, and the collar to limit the locking block. This prevents the locking block from rotating after moving to the first and second insertion platforms, thus preventing the winding terminal body from rotating and affecting the normal use of the wire.

[0013] As a preferred embodiment of the present invention, two slidable movable blocks are also provided on the two fixed plates. Each movable block has a pressure rod fixed to its top. The upper half of the two pressure rods is provided with two fixing holes that are adapted to the locking rods. The two locking rods extend to the other side of the pressure rods after passing through the two fixing holes. The two locking rods are also provided with two knobs that are easy for people to grip.

[0014] As a preferred embodiment of the present invention, the bottom of the movable block is provided with a sliding groove adapted to the fixed plate. The inner wall of the sliding groove is symmetrically fixed with bosses. The side of the fixed plate is provided with a groove adapted to the bosses. A spring is also fixed to the top of the fixed plate. The top of the positioning rod passes through the fixed plate and is fixed with a limit ball. The top of the inner wall of the sliding groove is provided with an inclined groove adapted to the spring. Through the cooperation of the bosses and the grooves, the movable block can slide along the fixed plate. Through the cooperation of the spring and the inclined groove, the movable block moves between the limit ball and the spring. Through the cooperation of the spring and the limit ball, the movable block is limited.

[0015] As a preferred embodiment of the present invention, each of the two locking rods has a threaded portion on one side facing each other. The outer wall of the support column has a threaded hole adapted to the threaded portion, and the inner wall of the winding terminal body also has a locking hole adapted to the locking rod. By rotating the locking rod, the locking rod drives the threaded portion to rotate. After the threaded portion moves to the outside of the support column, it pulls the moving block to move. After the moving block moves between the limiting ball and the spring, the moving block drives the locking rod to move through the pressure rod, so that the locking rod is inserted into the locking hole. The locking hole limits the locking rod, the locking rod limits the moving block through the pressure rod, the moving block limits the fixing plate, and the fixing plate limits the locking sleeve, preventing the locking sleeve from moving up and down after being fixed, and increasing the stability when multiple winding terminal bodies are stacked and do not need to be disassembled.

[0016] As a preferred embodiment of the present invention, the self-locking assembly includes two locking plates fixed to the bottom of another winding terminal body and two detachable inclined locking pins disposed on the upper half of the base. The top of the base is provided with connecting grooves that are compatible with the two locking plates, and the lower half of the locking plates is provided with self-locking grooves that are compatible with the inclined locking pins. After the inclined locking pins are pushed into the interior of the base, the base passes through the self-locking groove and limits the locking plates, thereby installing the winding terminal body with the locking plates on the top of the base, which facilitates the replacement of the base.

[0017] As a preferred embodiment of the present invention, the top of the cable management post is provided with a conductor platform, the conductor platform is provided with multiple cable routing grooves to separate the wires, and a rotatable winding post is provided above the conductor platform. The winding post is provided with a cable snagging groove in the middle, and the bottom of the base is also provided with multiple bolt mounting seats. The cable snagging groove facilitates the storage of the wires, and the cable routing groove facilitates the separation of the wires. The top of the cable management post is provided with a sleeve, and a support rod is fixed inside the sleeve. The top of the support rod is fixed to the bottom of the conductor platform. The outer wall of the sleeve is provided with two mounting brackets. The two mounting brackets penetrate the cable management post and are inserted into the load-bearing plate of the uppermost winding terminal body, thereby increasing the stability of the cable management post in use and preventing the cable management post from bending due to the large weight or tension of the wires.

[0018] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0019] The system utilizes a combination of components such as a plug-in device, a fixing device, a first plug-in platform, a second plug-in platform, a support column, a locking sleeve, a collar, and a locking block to disassemble multiple winding terminal bodies. This allows for the individual replacement of damaged winding terminal bodies, reducing losses and lowering power maintenance costs. It is also easy for power personnel to carry and the installation process is simple, convenient, and quick.

[0020] By rotating the locking rod, the threaded part rotates and moves to the outside of the support column. This moves the moving block between the limiting ball and the spring plate. The moving block then moves the locking rod through the pressure rod, inserting it into the lock hole. The lock hole limits the locking rod, and the locking rod limits the moving block through the pressure rod. The moving block limits the fixed plate, preventing the fixed plate from swaying up and down in extreme weather. This separates the positioning rod from the load-bearing plate, ensuring the device can be used normally.

[0021] After the inclined locking pin is pushed into the interior of the base, the base passes through the self-locking groove and limits the position of the locking plate, thereby installing the winding terminal body with the locking plate on the top of the base, making it convenient for people to replace the base.

[0022] The cable tray facilitates the storage of wires, and the cable runner facilitates the separation of wires. Two mounting brackets pass through the cable management post and are inserted into the load-bearing plate of the uppermost winding terminal body, thereby increasing the stability of the cable management post in use and preventing the cable management post from bending due to the weight or tension of the wires.

Detailed Implementation

[0033] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0034] Example: The present invention provides, as follows Figure 1 The electrically insulated wire-wound terminal shown includes:

[0035] The base 1 has multiple winding terminal bodies 2 on its top, and one of the winding terminal bodies 2 has a cable management post 5 on its top to limit the movement of the wire.

[0036] As can be seen from the above, when in use, the base 1 is installed on the utility pole where wiring is required, and the excess wire is wound around the winding terminal body 2 to fix the wire between multiple winding terminal bodies 2.

[0037] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, multiple plug-in devices 3 are provided inside the multiple winding terminal bodies 2. A self-locking component is provided between the base 1 and the lowest winding terminal body 2. Multiple fixing devices 4 are provided at the bottom of the multiple plug-in devices 3 to fix them. Through the cooperation of the multiple plug-in devices 3 and the multiple fixing devices 4, the multiple winding terminal bodies 2 are locked and fixed, so that the multiple winding terminal bodies 2 are stacked.

[0038] The plug-in device 3 includes a first plug platform 301 disposed inside the winding terminal body 2. A connecting rod is fixed to the bottom of the first plug platform 301, and a support column 303 is fixed to the bottom of the connecting rod. A second plug platform 302 that can be raised and lowered is provided on the lower half of the connecting rod. Two detachable locking rods 304 are symmetrically arranged on the outer wall of the support column 303. Both the first plug platform 301 and the second plug platform 302 are designed as flat-topped cones. The wider parts of the first plug platform 301 and the second plug platform 302 are located on the same side. The wider end of the second plug platform 302 is also provided with an arc-shaped chamfer. A trapezoidal groove is opened at the bottom of the second plug platform 302. The top of the connecting rod is fixed to the top of the groove.

[0039] The fixing device 4 includes a locking sleeve 401 disposed at the bottom of the support column 303. The middle part of the locking sleeve 401 is recessed inward to form a cavity that fits the support column 303. A collar 402 is fixed to the lower half of the locking sleeve 401. Two retractable locking blocks 411 are disposed inside the collar 402. Both locking blocks 411 have inclined surfaces on their opposing sides. Multiple observation slots are provided on the outer wall of the locking sleeve 401 to facilitate observation of the internal condition of the locking sleeve 401. The device is secured by two stacked winding terminal bodies 2. After the collar 402 inside one of the winding terminal bodies 2 is fitted over another first insertion platform 301, the collar 402 drives two locking blocks 411 to move. The inclined surfaces of the two locking blocks 411 move along the outer wall of the first insertion platform 301, so that the locking blocks 411 move between the first insertion platform 301 and the second insertion platform 302. The opposing sides of the two locking blocks 411 contact the outer wall of the connecting rod. The first insertion platform 301 is limited by the two locking blocks 411, thereby fixing multiple winding terminal bodies 2.

[0040] Two baffles are fixed on opposite sides of the two locking blocks 411. A telescopic post 409 is fixed to the end of the two baffles away from the locking blocks 411. The end of the telescopic post 409 away from the locking blocks 411 passes through the locking sleeve 401 and is inserted into the inside of the collar 402. The inner wall of the collar 402 has a telescopic groove adapted to the telescopic post 409. A second spring 410 is installed inside the telescopic groove. The free end of the second spring 410 is fixed to the end of the telescopic post 409 away from the locking blocks 411. By compressing the second spring 410, the locking blocks 411 can move quickly along the outer wall of the first insertion platform 301. When the locking blocks 411 move to the bottom of the first insertion platform 301, the second spring 410 releases its elastic force to push the telescopic post 409 to move. The telescopic post 409 pushes the locking blocks 411 between the first insertion platform 301 and the second insertion platform 302 through the baffles.

[0041] Two fixing plates 403 are symmetrically fixed to the upper half of the outer wall of the locking sleeve 401. Each fixing plate 403 has a liftable positioning rod 404 at its end away from the locking sleeve 401. Two load-bearing plates 408 are symmetrically fixed to the inner wall of the winding terminal body 2. Each load-bearing plate 408 has a mounting hole at its end away from the winding terminal body 2 that matches the positioning rod 404. A first spring 405 is fixed to the bottom of each fixing plate 403. The free end of the first spring 405 is connected to the top of the load-bearing plate 408. When in contact with each other, the positioning rod 404 is inserted into the mounting hole, so that the load-bearing plate 408 limits the positioning rod 404, the positioning rod 404 limits the fixing plate 403, the fixing plate 403 limits the locking sleeve 401, the locking sleeve 401 limits the collar 402, and the collar 402 limits the locking block 411. This can prevent the locking block 411 from rotating after moving to the first insertion platform 301 and the second insertion platform 302, causing the winding terminal body 2 to rotate and affecting the normal use of the wire.

[0042] By adopting the above technical solution:

[0043] In use, when it is necessary to replace the damaged winding terminal body 2, push down the first insertion platform 301 located in the topmost winding terminal body 2. The first insertion platform 301 drives the support column 303 to move downward through the connecting rod, causing the support column 303 to drive the locking sleeve 401 to move downward, causing the locking sleeve 401 to drive the locking block 411 to move downward, so that the inclined surface of the locking block 411 contacts the chamfer of the second insertion platform 302 and then contacts the outer wall of the second insertion platform 302. The second spring 410 releases its elastic force to move the locking block 411, so that the locking block 411 moves to the bottom of the second insertion platform 302. At the same time, the locking sleeve 401 drives the fixing plate 403 to move downward. The fixing plate 403 compresses the first spring 405, and the first spring 405 deforms to generate elastic force, causing the first spring 405 to push the fixing plate 403 upward, fixing it in place. Plate 403 drives the locking block 411 upward through the locking sleeve 401, causing the locking block 411 to drive the second insertion platform 302 upward. After the top of the second insertion platform 302 contacts the bottom of the first insertion platform 301, the first insertion platform 301 limits the second insertion platform 302. The locking block 411 moves upward along the outer wall of the second insertion platform 302 and then continues to move upward along the outer wall of the first insertion platform 301. The locking block 411 drives the locking sleeve 401 upward, separating the locking sleeve 401 from the second insertion platform 302. The second insertion platform 302 moves to the outside of the locking sleeve 401. At the same time, the locking sleeve 401 drives the positioning rod 404 to move to the outside of the load-bearing plate 408 through the fixing plate 403, completing the disassembly of multiple winding terminal bodies 2. This makes it easy to replace the damaged winding terminal bodies 2 individually. The operation is simple, convenient and quick.

[0044] Secondly, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, two sliding movable blocks 306 are also provided on the two fixed plates 403. Each movable block 306 has a pressure rod 305 fixed on its top. The upper half of the two pressure rods 305 is provided with two fixing holes that are compatible with the locking rods 304. The two locking rods 304 extend through the two fixing holes to the other side of the pressure rods 305. The two locking rods 304 are also provided with two knobs that are easy for people to grip.

[0045] The bottom of the movable block 306 is provided with a sliding groove that matches the fixed plate 403. The inner wall of the sliding groove is symmetrically fixed with bosses. The side of the fixed plate 403 is provided with a groove that matches the bosses. The top of the fixed plate 403 is also fixed with a spring piece 407. The top of the positioning rod 404 passes through the fixed plate 403 and is fixed with a limit ball 406. The top of the inner wall of the sliding groove is provided with an inclined groove that matches the spring piece 407. Through the cooperation of the boss and the groove, the movable block 306 can slide along the fixed plate 403. Through the cooperation of the spring piece 407 and the inclined groove, the movable block 306 moves between the limit ball 406 and the spring piece 407. Through the cooperation of the spring piece 407 and the limit ball 406, the movable block 306 is limited.

[0046] Both locking rods 304 have threaded portions on their opposing sides. The outer wall of the support column 303 has threaded holes that match the threaded portions, and the inner wall of the winding terminal body 2 also has locking holes that match the locking rods 304. By rotating the locking rods 304, the locking rods 304 drive the threaded portions to rotate, causing the threaded portions to move to the outside of the support column 303. This pulls the moving block 306 to move, causing the moving block 306 to move between the limiting ball 406 and the spring piece 407. Block 306 moves the locking rod 304 via pressure rod 305, causing the locking rod 304 to be inserted into the lock hole. The lock hole limits the locking rod 304, and the locking rod 304 limits the moving block 306 via pressure rod 305. The moving block 306 limits the fixing plate 403, and the fixing plate 403 limits the lock sleeve 401, preventing the lock sleeve 401 from moving up and down after being fixed, thus increasing the stability when multiple winding terminal bodies 2 are stacked and do not need to be disassembled.

[0047] By adopting the above technical solution:

[0048] In use, rotating the locking rod 304 causes the threaded part to rotate, moving it to the outside of the support column 303. This then pulls the moving block 306, moving it between the limiting ball 406 and the spring piece 407. The moving block 306 then moves the locking rod 304 via the pressure rod 305, inserting it into the lock hole. The lock hole limits the locking rod 304, which in turn limits the moving block 306 via the pressure rod 305. The moving block 306 then limits the fixed plate 403, preventing the fixed plate 403 from swaying up and down in extreme weather conditions, which could cause the positioning rod 404 to separate from the load-bearing plate 408 and render the device unusable.

[0049] Again, refer to Figure 1 and Figure 8As shown, the self-locking assembly includes two locking plates 8 fixed to the bottom of another winding terminal body 2 and two detachable inclined locking pins 9 disposed on the upper half of the base 1. The top of the base 1 is provided with connecting grooves that are compatible with the two locking plates 8, and the lower half of the locking plates 8 is provided with self-locking grooves that are compatible with the inclined locking pins 9. After pushing the inclined locking pins 9 into the interior of the base 1, the base 1 passes through the self-locking groove and limits the locking plates 8, thereby installing the winding terminal body 2 with the locking plates 8 on the top of the base 1, which makes it convenient for people to replace the base 1.

[0050] By adopting the above technical solution:

[0051] In use, by pushing the inclined locking pin 9 into the interior of the base 1, the base 1 passes through the self-locking groove and limits the position of the locking plate 8, thereby installing the winding terminal body 2 with the locking plate 8 on the top of the base 1, making it convenient for people to replace the base 1.

[0052] Finally, refer to Figure 1 and Figure 9 As shown, the top of the cable management post 5 is equipped with a conductor platform 6, which has multiple cable routing channels to separate the wires. Above the conductor platform 6 is a rotatable winding post 7, with a cable snagging channel in the middle. The bottom of the base 1 is also equipped with multiple bolt mounting seats. The cable snagging channel facilitates the storage of wires, and the cable routing channel facilitates the separation of wires. The top of the cable management post 5 is equipped with a sleeve, and a support rod is fixed inside the sleeve. The top of the support rod is fixed to the bottom of the conductor platform 6. The outer wall of the sleeve is equipped with two mounting brackets. The two mounting brackets pass through the cable management post 5 and are inserted into the load-bearing plate 408 of the uppermost winding terminal body 2. This can increase the stability of the cable management post 5 in use and prevent the cable management post 5 from bending due to the large weight or tension of the wires.

[0053] By adopting the above technical solution:

[0054] In use, the cable tray facilitates the storage of wires, and the cable routing tray facilitates the separation of wires. The two mounting brackets pass through the cable management post 5 and are inserted into the load-bearing plate 408 of the uppermost winding terminal body 2, thereby increasing the stability of the cable management post 5 in use and preventing the cable management post 5 from bending due to the large weight or tension of the wires.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
