Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terminal block technology, and in particular relates to a traction substation terminal block with an anti-accidental contact structure. Background Technology
[0002] Traction substation terminals are core components in traction substations used to achieve electrical connections. Their main function is to reliably connect the wires or cables of equipment such as transformers, circuit breakers, and disconnect switches to ensure stable current transmission in traction power supply systems (such as railways and urban rail transit).
[0003] If the traction substation terminal is accidentally touched during use, it may cause the terminal to become loose, the wire to fall off, or the short circuit between the terminals. The instantaneous large current will burn the terminal and cable, and may even damage core equipment such as transformers and circuit breakers, greatly increasing maintenance costs and downtime.
[0004] In the use of existing equipment, when the terminal block needs to be connected to the line, the protection often needs to be removed. The terminal block is inevitably exposed to the outside world, which poses a certain risk. It is not good to ensure that the terminal block is still protected during the connection. The terminal block may be damaged due to excessive accidental contact, resulting in poor reliability. Therefore, we propose a traction substation terminal block with an anti-accidental contact structure. Utility Model Content
[0005] The purpose of this utility model is to provide a traction substation terminal block with an anti-accidental contact structure. Through the anti-accidental contact mechanism and the protective mechanism, the problem is solved that when the terminal block needs to be connected to the line, the protection often needs to be removed, and the terminal block is inevitably exposed to the outside world, which poses a certain risk. It is not good to ensure that the terminal block is still protected during the connection. The terminal block may be damaged due to excessive accidental contact, resulting in poor reliability.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a traction substation terminal block with an anti-accidental contact structure, including a fixed box, the inner wall of which is fixedly connected with a terminal block, and the inner wall of the fixed box is provided with an anti-accidental contact mechanism.
[0008] The anti-accidental contact mechanism includes a protective cover, the outer wall of which is rotatably connected to the inner wall of a fixed box. A front cover is rotatably connected to the inner wall of the fixed box. A handle is fixedly connected to the outer wall of the front cover. A slot is formed in the inner wall of the front cover. A locking piece is rotatably connected to the inner wall of the protective cover. A knob is fixedly connected to the outer wall of the locking piece. The knob passes through the protective cover to the outer wall. A pin groove is formed in the inner wall of the fixed box. A fixing pin is slidably connected to the inner wall of the pin groove. A spring is fixedly connected to the outer wall of the fixing pin. The outer wall of the spring is fixedly connected to the inner wall of the pin groove. A push button is fixedly connected to the outer wall of the fixing pin. A fixing groove is formed in the inner wall of the protective cover. The inner wall of the fixing groove is slidably connected to the outer wall of the fixing pin.
[0009] Furthermore, the outer wall of the fixed box is provided with a protective mechanism, which includes a threaded rod seat. The outer wall of the threaded rod seat is fixedly connected to the outer wall of the fixed box, and the inner wall of the threaded rod seat is threadedly connected with a threaded rod.
[0010] Furthermore, a knob two is fixedly connected to the top outer wall of the threaded rod, a connecting frame is rotatably connected to the bottom outer wall of the threaded rod, a protective plate is fixedly connected to the outer wall of the connecting frame, and several racks are fixedly connected to the outer wall of the connecting frame.
[0011] Furthermore, the inner wall of the fixed box is provided with a plurality of rack grooves, and the inner walls of the plurality of rack grooves are slidably connected to the outer wall of the rack.
[0012] Furthermore, the outer wall of the fixed box is rotatably connected to several gears, and the outer walls of the several gears mesh with the outer wall of the rack.
[0013] Furthermore, the inner wall of the fixed box is provided with a plurality of rack grooves, and racks are slidably connected to the inner walls of the plurality of rack grooves.
[0014] Furthermore, the outer walls of several racks II mesh with the outer walls of gears, and a connecting frame II is fixedly connected to the outer walls of several racks II.
[0015] Furthermore, a protective plate is fixedly connected to the outer wall of the connecting frame two, and several buttons are slidably connected to the inner wall of the wiring terminal.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model features a fixing pin. Pushing the button downwards displaces the fixing pin, causing it to disengage from the fixing groove and simultaneously compress the spring. This allows the protective cover to be opened, and the wiring to be connected to the terminal block. After connection, rotating the knob clockwise by 45 degrees causes the locking plate to rotate, disengaging from the slot and no longer restricting the front cover's rotation. Then, while holding the button down, rotate the protective cover back to its original position, and release the button. This design ensures reliable protection for the terminal block even when connected to the wiring, minimizing direct exposure and preventing damage from accidental contact.
[0018] 2. This utility model incorporates a protective plate. During operation, the protective plate and the second protective plate together prevent several buttons from directly contacting the outside. If operation of several buttons is required, the second knob can be rotated counterclockwise. The second knob will drive the threaded rod to rotate and rise, which in turn will drive the connecting frame to rise. The connecting frame will then drive several racks and the protective plate to rise together. Each rack will drive a gear to rotate, which in turn will drive the second rack to move. The second rack will then drive the second protective plate to move downwards, causing the connecting frame and the protective plate to move away from each other, thus exposing the buttons to the outside for user operation. This achieves comprehensive protection of the buttons, preventing accidental activation by the user in unnecessary situations, and ensuring high reliability.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The anti-accidental touch mechanism 2 includes a protective cover 201. The outer wall of the protective cover 201 is rotatably connected to the inner wall of the fixed box 1. A front cover 202 is rotatably connected to the inner wall of the fixed box 1. The fixed box 1 mainly serves to limit the rotation of the protective cover 201, allowing one end of the protective cover 201 to rotate only in a fixed position within the fixed box 1. A handle 203 is fixedly connected to the outer wall of the front cover 202. A slot 204 is provided on the inner wall of the front cover 202. A locking piece 205 is rotatably connected to the inner wall of the protective cover 201, also limiting its rotation. The locking piece 205 can only rotate in a fixed position within the protective cover 201. A knob 206 is fixedly connected to the outer wall of the locking piece 205, penetrating the protective cover. From 201 to the outer wall, the inner wall of the fixed box 1 is provided with a pin groove 207. The shape of the knob 206 is convenient for the user to hold and rotate. When the knob 206 is rotated, it will drive the locking piece 205 to rotate together. The inner wall of the pin groove 207 is slidably connected to the fixing pin 208. The outer wall of the fixing pin 208 is fixedly connected to the spring 209. The outer wall of the spring 209 is fixedly connected to the inner wall of the pin groove 207. The pin groove 207 mainly plays the role of sliding limit for the fixing pin 208. The fixing pin 208 can only slide within the pin groove 207 at a fixed angle. The outer wall of the fixing pin 208 is fixedly connected to the push button 210. The inner wall of the protective cover 201 is provided with a fixing groove 211. The inner wall of the fixing groove 211 is slidably connected to the outer wall of the fixing pin 208.
[0031] The outer wall of the fixed box 1 is provided with a protective mechanism 3, which includes a threaded rod seat 301. The outer wall of the threaded rod seat 301 is fixedly connected to the outer wall of the fixed box 1. The fixed box 1 mainly serves to fix and limit the threaded rod seat 301, which can only be fixed in the fixed box 1. A threaded rod 302 is threadedly connected to the inner wall of the threaded rod seat 301. A knob 303 is fixedly connected to the top outer wall of the threaded rod 302. A connecting bracket 304 is rotatably connected to the bottom outer wall of the threaded rod 302. The knob 303 has the following shape. It is easy for the user to hold and rotate. When the knob 303 is rotated, it will drive the threaded rod 302 to rotate as well. The outer wall of the connecting frame 304 is fixedly connected to the protective plate 305. Several racks 306 are fixedly connected to the outer wall of the connecting frame 304. Several rack grooves 307 are opened on the inner wall of the fixed box 1. The inner wall of the rack grooves 307 is slidably connected to the outer wall of the rack 306. The rack grooves 307 mainly play the role of sliding limit for the rack 306. The rack 306 can only slide at a fixed angle within the rack grooves 307.
[0032] The outer wall of the fixed box 1 is rotatably connected to several gears 308, and the outer walls of the gears 308 mesh with the outer walls of the racks 306. The inner wall of the fixed box 1 is provided with several rack grooves 309. The racks 306 mainly play the role of transmitting kinetic energy to the gears 308. When the racks 306 are displaced, they will drive the gears 308 to rotate simultaneously. The inner walls of the rack grooves 309 are slidably connected to racks 310. The outer walls of the racks 310 mesh with the outer walls of the gears 308. The outer walls of the racks 310 are fixedly connected to connecting brackets 311. The rack grooves 309 mainly play the role of sliding limit for the racks 310. The racks 310 can only slide within the rack grooves 309 at a fixed angle. The outer wall of the connecting brackets 311 is fixedly connected to a protective plate 312. The inner wall of the terminal block 101 is slidably connected to several buttons 313.
[0033] One specific application of this embodiment is:
[0034] When staff need to use the equipment, the protective cover 201 and the front cover 202 will securely protect the terminal block 101 to prevent accidental contact and damage. To connect the terminal block 101 to an external circuit, push the push button 210 downwards. The push button 210 will displace the fixing pin 208, causing it to disengage from the fixing groove 211 and simultaneously compress the spring 209. At this point, the protective cover 201 can be lifted, and the circuit can be connected to the terminal block 101. After connection, turn the knob 206 clockwise by 45 degrees. The knob 206 will rotate the locking piece 205, causing it to disengage from the slot 204 and no longer restrict the rotation of the front cover 202. Then, while holding the push button 210 down, rotate the protective cover 201 back to its original position. Release the push button 210, and the fixing pin 208 will automatically reset under the action of the spring 209 and insert into the fixing groove 211 to restrict the rotation of the protective cover 201. Meanwhile, the front cover 202 is no longer held in place by the locking piece 205, allowing it to rotate freely and thus creating an opening in the protective cover 201. This prevents external wiring from being clamped while protecting the terminal block 101. During this time, the protective plate 305 and the second protective plate 312 together prevent several buttons 313 from directly contacting the outside. If it is necessary to operate several buttons 313, the knob 303 can be turned counterclockwise. The knob 303 will drive the threaded rod 302 to rotate and rise. The threaded rod 302 will drive the connecting frame 304 to rise. The connecting frame 304 will drive several racks 306 and the protective plate 305 to rise together. Several racks 306 will drive gears 308 to rotate. Several gears 308 will drive rack 310 to move. Several racks 310 will drive the protective plate 312 to move downward. The connecting frame 311 and the protective plate 305 will move away from each other so that several buttons 313 are exposed to the outside for user operation.
