Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to a redundant communication terminal device. Background Technology

[0002] Redundant communication equipment is a general term for communication equipment with redundant hardware, link, and protocol designs, enabling automatic fault detection, seamless switching, and uninterrupted communication. It is mainly divided into four categories: redundant communication terminals, redundant networking equipment, redundant data processing equipment, and redundant supporting equipment. Its working modes are divided into interface-level redundancy and whole-machine-level redundancy. Its core value is to solve the single point of failure problem of communication systems and to ensure communication security in critical scenarios such as power, industry, and rail transportation. The core difference between it and ordinary communication equipment is automatic switching, fault self-healing, and uninterrupted communication. All industrial or field-level devices in redundant communication terminal equipment require physical wiring, while only pure virtualized terminals do not require wiring. The core devices that need wiring cover core categories such as field data acquisition, link access, and power supply. The wiring mainly revolves around three core dimensions: power supply, communication link, and field device interconnection. Due to the redundant design, the wiring of these devices is dual-redundant wiring. During the use of redundant equipment, the equipment is often deployed in harsh environments such as industrial sites, substations, vehicles, and outdoors. During use, the continuous vibration of factory motors, rail vehicles, and outdoor fans will generate vibration stress. Vibration stress will cause the terminal screws to gradually loosen, resulting in the wiring falling off the redundant equipment. In addition, because there are more wirings in the redundant interface, the vibration transmission is more obvious, which will increase the probability of wiring falling off.

[0003] In summary, to solve the technical problems proposed in this paper, this invention proposes a redundant communication terminal device. Summary of the Invention

[0004] To address the aforementioned issue of vibration stress generated by the continuous vibration of factory motors, rail vehicles, and outdoor fans during the use of existing equipment, which can gradually loosen terminal screws and cause wiring to detach from redundant devices, and because redundant interfaces have more wiring, vibration transmission is more pronounced, increasing the probability of wiring detachment, this invention proposes a redundant communication terminal device. This redundant communication terminal device includes a device body and a terminal block; the terminal block is located at the end of the device body; the terminal block includes: The mounting slot is located inside the device body, and the device body has a wiring slot that is connected to the mounting slot. There are two mounting columns, one above the other, located on one side of the equipment body. One end of each mounting column penetrates the equipment body and is located inside the mounting groove, while the other end is located outside the equipment body. A gear ring is provided on the outer side of the mounting column located outside the equipment body, and a gear disk is provided between the two mounting columns. The gear disk meshes with the gear ring between the two mounting columns, and a knob is provided on the gear disk. A slider is provided on the outer side of the end of the mounting column located inside the mounting groove. The conductive post is located inside the mounting groove, and a cylindrical groove is formed at one end of the conductive post near the mounting post. The mounting post is slidably connected inside the cylindrical groove, and a sliding groove is formed on the inner wall of the cylindrical groove. The slider is slidably connected inside the sliding groove, so that the conductive post can slide back and forth inside the mounting post without rotating. Multiple conductive sheets are wrapped around the outside of the conductive post. Slots are evenly formed on the conductive post, and the slots pass through the conductive sheets and the conductive post. A rectangular block is located inside the end of the mounting groove away from the mounting post, and two guide grooves are opened at the top and bottom of the rectangular block near the mounting post, with the conductive post slidably connected inside the guide grooves.

[0005] As a preferred embodiment of this application, the inner wall of the guide groove is provided with a spiral groove, the end of the conductive post away from the mounting post is slidably connected to the inside of the guide groove, and an adjustment block is provided on the outside of the conductive post, the adjustment block being slidably connected to the inside of the spiral groove.

[0006] As a preferred embodiment of this application, an arc-shaped plate is slidably connected to one end of the rectangular block near the mounting post. In the initial state, the arc-shaped plate is in contact with the conductive sheet on the outside of the conductive post, and the end of the arc-shaped plate in contact with the conductive sheet is roughened, and the arc-shaped plate does not close the slot.

[0007] As a preferred embodiment of this application, a through groove is provided on the arc plate, and in the initial state, the through groove is connected to the slot.

[0008] As a preferred embodiment of this application, the conductive post is provided with annular grooves evenly distributed on it, and the annular grooves are located between adjacent conductive sheets.

[0009] As a preferred embodiment of this application, a take-up reel is provided at one end of the mounting column inside the mounting groove, and a take-up tape is wound on the take-up reel; a sealing plate is provided on the outside of the equipment body, and the sealing plate is located at the end of the equipment body near the insertion groove; rectangular grooves are opened on both sides of the end of the equipment body near the insertion groove; a connecting rod is provided at the end of the sealing plate near the equipment body, and the connecting rod is slidably connected inside the rectangular groove; the end of the take-up tape away from the take-up reel passes through the inner wall of the mounting groove and connects to the sealing plate; an annular rubber belt is provided on the equipment body, and the annular rubber belt is located on the outer ring of the insertion groove; a connecting hole is opened on the sealing plate; when the sealing plate is close to the equipment body, the outer ring of the connecting hole on the sealing plate squeezes the annular rubber belt.

[0010] As a preferred embodiment of this application, the rectangular groove is inclined, the connecting rod is inclined, and in the initial state, the sealing plate and the device body are not in contact, and the connecting hole coincides with the wire insertion groove.

[0011] As a preferred embodiment of this application, a groove is provided at one end of the sealing plate near the equipment body, and the width of the groove is the same as the outer diameter of the annular rubber belt. When the sealing plate contacts the annular rubber belt, the annular rubber belt enters the interior of the groove.

[0012] The beneficial effects of this invention are as follows: As the conductive post slides inside the guide groove, the adjusting block slides in the spiral groove. This causes the conductive post to wrap around the wire in a spiral shape on the conductive sheet outside the conductive post, thus preventing the wire from stacking on the conductive sheet when it is wrapped around the conductive post. Furthermore, when the wire is spirally wrapped around the conductive sheet outside the conductive post, the arc plate presses against the wire, ensuring a tight contact between the wire and the conductive sheet, thus preventing any slack between them. This also prevents the wire from detaching from the conductive sheet due to mechanical vibration when used in the external environment. Attached Figure Description

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] Example 1: like Figures 1 to 10 As shown; a redundant communication terminal device, the redundant communication terminal device includes a device body 1 and a terminal block 2; the terminal block 2 is located at the end of the device body 1; the terminal block 2 includes: The mounting slot 21 is located inside the device body 1, and the device body 1 has a wire insertion slot 22, which is connected to the mounting slot 21. There are two mounting posts 23, which are distributed vertically on one side of the equipment body 1. One end of the mounting post 23 penetrates the equipment body 1 and is located inside the mounting groove 21, while the other end is located outside the equipment body 1. A gear ring 231 is provided on the outside of the mounting post 23 located outside the equipment body 1, and a gear disk 232 is provided between the two mounting posts 23. The gear disk 232 meshes with the gear ring 231 between the two mounting posts 23. A knob 233 is provided on the gear disk 232. A slider 234 is provided on the outside of the end of the mounting post 23 located inside the mounting groove 21. A conductive post 24 is disposed inside the mounting groove 21, and a cylindrical groove 241 is formed at one end of the conductive post 24 near the mounting post 23. The mounting post 23 is slidably connected inside the cylindrical groove 241, and a sliding groove 242 is formed on the inner wall of the cylindrical groove 241. A slider 234 is slidably connected inside the sliding groove 242, so that the conductive post 24 can slide back and forth inside the mounting post 23 without rotating. Multiple conductive sheets 243 are wrapped around the outside of the conductive post 24. Slots 244 are evenly formed on the conductive post 24, and the slots 244 penetrate the conductive sheets 243 and the conductive post 24. A rectangular block 25 is disposed inside the end of the mounting groove 21 away from the mounting post 23, and two guide grooves 251 are provided at the upper and lower ends of the rectangular block 25 near the mounting post 23, and the conductive post 24 is slidably connected inside the guide groove 251. The inner wall of the guide groove 251 is provided with a spiral groove 252. The end of the conductive post 24 away from the mounting post 23 is slidably connected to the inside of the guide groove 251, and an adjustment block 253 is provided on the outside of the conductive post 24. The adjustment block 253 is slidably connected to the inside of the spiral groove 252. An arc-shaped plate 26 is slidably connected to one end of the rectangular block 25 near the mounting post 23. In the initial state, the arc-shaped plate 26 is in contact with the conductive sheet 243 on the outside of the conductive post 24, and the end of the arc-shaped plate 26 in contact with the conductive sheet 243 is rough, and the arc-shaped plate 26 does not close the slot 244. The specific workflow is as follows; When in use, the operator first peels off the outer insulation layer of the wiring. Then, the operator inserts the wiring into the mounting slot 21 on the device body 1 through the plug-in slot. During this process, the mounting post 23, conductive post 24, and conductive plate 243 are in their initial state. At this time, the slots 244 on the conductive post 24 and conductive plate 243 coincide with the plug-in slot on the device body 1, so that when the wiring is inserted into the mounting slot 21, the wiring will be inserted into the slot 244 through the plug-in slot 22. After the wiring is inserted into the slot 244, the operator manually rotates the knob. 233, the knob 233 will drive the gear disk 232 to rotate counterclockwise. Since the gear disk 232 meshes with the gear rings 231 on the outer sides of the upper and lower mounting posts 23, the gear disk 232 drives the two gear rings 231 to rotate. The gear rings 231 cause the two mounting posts 23 to rotate clockwise. When the mounting posts 23 rotate clockwise, the end of the mounting post 23 located inside the mounting groove 21 rotates synchronously. Since the mounting groove 21 is provided with a conductive post 24, the end of the conductive post 24 away from the gear disk 232 extends into the guide groove 251 inside the rectangular block 25. A cylindrical groove 241 is provided at one end near the gear disk 232, allowing the mounting post 23 to extend into the groove 241. A sliding groove 242 is provided inside the cylindrical groove 241. A slider 234 is provided on the outer side of the mounting post 23, and the slider 234 is slidably connected to the sliding groove. This ensures that when the mounting post 23 slides inside the cylindrical groove 241, it can only reciprocate within the groove and cannot rotate. When the knob 233 is rotated, both mounting posts 23 rotate, causing the slider to move. When the slider 234 rotates and moves inside the cylindrical groove 241, it pushes against the groove wall of the groove 242, causing the slider 234 to transmit rotational force to the conductive post 24. This causes the mounting post 23 to drive the conductive post 24 to rotate, and the conductive post 24 rotates in the guide groove 251 on the rectangular block 25. When the conductive post 24 rotates, the wire is inserted into the slot 244, causing the slot 244 to bend the wire as the conductive post 24 rotates. The wire rotates with the conductive post 24 and wraps around the conductive sheet 243 on the outside of the conductive post 24.Furthermore, an arc-shaped plate 26 is slidably connected to the rectangular block 25. Specifically, a rectangular groove 11 is formed on the rectangular block 25, allowing the arc-shaped plate 26 to slide within the groove 11. Initially, the inner wall of the arc-shaped plate 26 is in contact with the conductive sheet 243, and the end of the arc-shaped plate 26 has an arc-shaped transition. During the rotation of the conductive post 24, initially, the conductive post 24 drives the wiring to rotate. During the rotation of the wiring, the arc-shaped plate 26 squeezes the wiring, causing it to bend. As the conductive post 24 rotates, the bent wiring enters between the arc-shaped plate 26 and the conductive sheet 243. As the conductive post 24 rotates, it wraps around the wiring. During this process, the arc-shaped plate 26 limits the wiring, ensuring that the arc-shaped plate 26 is tightly attached to the outer ring of the conductive sheet 243, thereby preventing loosening between the wiring and the conductive sheet 243. The conductive post 24 is in a relaxed state; and during the rotation of the conductive post 24, a spiral groove 252 is provided on the inner wall of the guide groove 251, and an adjusting block 253 is provided at one end of the conductive post 24 located inside the guide groove 251, so that the adjusting block 253 is slidably connected to the inside of the spiral groove 252. When the conductive post 24 rotates, the adjusting block 253 on the outside of the conductive post 24 will rotate in the spiral groove 252, so that when the conductive post 24 rotates, the adjusting block 253 rotates in the spiral groove 252, so that when the conductive post 24 rotates, it slides into the inside of the guide groove 251. During the process, the conductive post 24 slides with the mounting post 23. Since the mounting post 23 cannot rotate with the inner wall of the cylindrical groove 241, the conductive post 24 rotates inside the guide groove 251 while the slider 234 slides inside the groove 242. While the conductive post 24 slides inside the guide groove 251, the adjusting block 253 slides in the spiral groove 252, causing the conductive post 24 to rotate. This allows the wire to spirally wrap around the conductive sheet 243 outside the conductive post 24 when the conductive post 24 is wrapped around it, thus avoiding the problem of the wire stacking on the conductive sheet 243 when the wire is wrapped around the conductive post 24. Furthermore, when the wire is spirally wrapped around the conductive sheet 243 outside the conductive post 24, the arc plate 26 presses the wire, ensuring a tight contact between the wire and the conductive sheet 243, thus preventing a loose state between the wire and the conductive sheet 243. This also prevents the wire from detaching from the conductive sheet 243 due to mechanical vibration when used in the external environment. Furthermore, when the terminal equipment needs to be repaired and the wiring needs to be disconnected from the equipment body 1, the operator can rotate the knob 233 clockwise to unwind the wiring with the conductive post 24. Then, the operator can manually pull the wiring on the outside of the equipment body 1 to disconnect the wiring from the mounting slot 21. During this process, due to the long-term use of the wiring and conductive sheet 243, the surface of the conductive core of the wiring will oxidize, and oxides will appear on the conductive sheet 243. When the conductive post 24 unwinds the wiring, the inner wall of the arc plate 26 will rub against the surface of the conductive core of the wiring, causing the inner wall of the arc plate 26 to scrape the surface of the conductive core, causing the oxide layer on the surface of the conductive core of the wiring to fall off, thereby preventing the oxide layer generated after long-term use from affecting the conductivity of the wiring. Furthermore, if an oxide layer appears on the surface of the conductive sheet 243 after prolonged use and during maintenance of the terminal equipment, causing an increase in resistance and a decrease in conductivity, the operator can remove the wiring from the mounting slot 21. At this time, the arc plate 26 will re-contact the outer side of the conductive sheet 243. Then, the operator can rotate the knob 233, causing the conductive post 24 to rotate. The conductive post 24 will then rotate the conductive sheet 243. When the conductive sheet 243 rotates, its outer side will contact the lower end of the arc plate 26. At this time, the inner wall of the arc plate 26 will rub against the outer ring of the conductive sheet 243. Since the inner wall of the arc plate 26 is rough, it will scrape off the oxide layer on the outer side of the conductive sheet 243, thereby restoring the conductivity of the conductive sheet 243.

[0016] Example 2: like Figures 1 to 10 As shown; a through slot 261 is provided on the arc plate 26, and in the initial state, the through slot 261 is connected to the slot 244; The conductive post 24 has annular grooves 245 evenly distributed on it, and the annular grooves 245 are located between adjacent conductive sheets 243. The specific workflow is as follows; Based on the above embodiment, a through groove 261 is opened on the arc plate 26. In the initial state, the through groove 261 is connected to the slot 244. When the wire is inserted into the slot 244, the wire passes through the through groove 261 and then enters the slot 244. After the wire is inserted, the operator rotates the knob 233. The knob 233 drives the gear disk 232 to rotate. The gear disk 232 meshes with the gear rings 231 on the two mounting posts 23, causing the gear disk 232 to drive the two mounting posts 23 to rotate. The two mounting posts 23 drive the conductive posts 24 to rotate, and the slots on the conductive posts 24... 244 rotates synchronously. In the initial stage of the rotation of the conductive post 24, the arc plate 26 will bend the wire. After the arc plate 26 is bent, the bent wire will enter the arc plate 26 as the conductive post 24 rotates. Then the wire will be wound on the conductive sheet 243 on the outside of the conductive post 24. During the winding process, the wire will contact the groove wall of the through groove 261. As the wire is wound, the groove wall of the through groove 261 will scrape the wire. When the repaired wire is wound onto the conductive sheet 243, the groove wall of the through groove 261 will clean the oxide layer on the outside of the wire, thereby preventing the oxide layer on the surface of the wire from affecting the conductivity of the wire. Furthermore, annular grooves 245 are evenly formed on the conductive post 24, and the annular grooves 245 are located between adjacent conductive sheets 243. Since there are multiple conductive sheets 243 on the conductive post 24, each conductive sheet 243 corresponds to a wire. When the wire is wound up, the wire is inserted into the corresponding slot 244, and then the conductive post 24 is rotated so that the wire is wound up by the conductive post 24, thereby winding the wire onto the conductive sheet 243. During this process, the conductive post 24 is rotatably connected in the guide groove 251, and the adjusting block 253 on the outside of the conductive post 24 slides. The spiral groove 252 connected to the inner wall of the guide groove 251 allows the conductive post 24 to slide synchronously into the guide groove 251 during rotation, thereby causing the wire to spirally wrap around the conductive sheet 243. During the winding of the conductive sheet 243, the annular groove 245 will block the close proximity of the conductive sheets 243. If the wire moves closer to another close conductive sheet 243 during the winding process of the wire on the conductive sheet 243, the wire will enter the annular groove 245, thereby preventing the corresponding wires on adjacent conductive sheets 243 from contacting each other. Example 3: like Figures 2 to 10As shown; a take-up reel 27 is provided at one end of the mounting post 23 inside the mounting groove 21, and a take-up tape 271 is wound on the take-up reel 27; a sealing plate 28 is provided on the outside of the equipment body 1, and the sealing plate 28 is located at the end of the equipment body 1 near the insertion groove 22; rectangular grooves 11 are opened on both sides of the end of the equipment body 1 located in the insertion groove 22; a connecting rod 12 is provided at the end of the sealing plate 28 near the equipment body 1, and the connecting rod 12 is slidably connected inside the rectangular groove 11; and the end of the take-up tape 271 away from the take-up reel 27 passes through the inner wall of the mounting groove 21 and connects to the sealing plate 28; an annular rubber belt 13 is provided on the equipment body 1, and the annular rubber belt 13 is located on the outer ring of the insertion groove 22; a connecting hole 281 is opened on the sealing plate 28; when the sealing plate 28 is close to the equipment body 1, the outer ring of the connecting hole 281 on the sealing plate 28 squeezes the annular rubber belt 13; The specific workflow is as follows; Based on the above embodiment, a take-up reel 27 is provided at one end of the mounting post 23 located inside the mounting groove 21, and a take-up tape 271 is wound on the take-up reel 27. When the knob 233 is rotated, the knob 233 drives the two mounting posts 23 to rotate through the gear disk 232, and the two mounting posts 23 drive the two conductive posts 24 to rotate. During the process, the two mounting posts 23 drive the take-up reel 27 to rotate, and the take-up reel 27 winds up the take-up tape 271. Furthermore, a sealing plate 28 is provided on the outside of the equipment body 1, and the sealing plate 28 is close to the equipment body 1. A connecting rod 12 is provided at one end, and a rectangular groove 11 is provided at one end of the equipment body 1 located in the insertion groove 22. The connecting rod 12 is slidably connected inside the rectangular groove 11. The end of the sealing plate 28 near the equipment body 1 is connected to the winding tape 271, and a connecting hole 281 is provided on the sealing plate 28. When installing the wiring, the wiring is passed through the connecting hole 281. After passing through the connecting hole 281, the wiring passes through the annular rubber tape 13. After passing through the annular rubber tape 13, the wiring enters the interior of the slot 244. Then, the operator rotates... Knob 233 rotates the mounting post 23, which in turn rotates the conductive post 24. The conductive post 24 retracts the cable, and during this process, the mounting post 23 rotates the winding reel 27, which in turn winds the winding tape 271. As the winding tape 271 winds, it pulls on the sealing plate 28. When the winding tape 271 pulls on the sealing plate 28, the connecting rod 12 on the sealing plate 28 slides into the rectangular groove 11. During this process, the sealing plate 28 moves towards the equipment body 1 until the conductive post 24 has finished winding the cable. The sealing plate 28 contacts the equipment body 1, and during the process, the sealing plate 28 will squeeze the annular rubber strip 13 at the end of the equipment body 1. Since the middle of the annular rubber strip 13 is hollow, the annular rubber strip 13 will deform after being squeezed. Specifically, the inner side of the annular rubber strip 13 will seal the wire slot 22. During the process, the inner side of the annular rubber strip 13 will simultaneously squeeze and limit the wiring inside the wire slot 22, thereby sealing the wiring of the annular rubber strip 13; thus preventing external moisture from entering the interior of the equipment body 1.

[0017] Example 4: like Figures 2 to 10 As shown; the rectangular groove 11 is inclined, the connecting rod 12 is inclined, and in the initial state, the closed plate 28 and the equipment body 1 are not in contact, and the connecting hole 281 coincides with the wire insertion groove 22; A groove 282 is provided at one end of the sealing plate 28 near the equipment body 1, and the width of the groove 282 is the same as the outer diameter of the annular rubber belt 13. When the sealing plate 28 contacts the annular rubber belt 13, the annular rubber belt 13 enters the interior of the groove 282. The specific workflow is as follows; Based on the above embodiment, the rectangular groove 11 is inclined, and the connecting rod 12 is also inclined. When the take-up reel 27 takes up the winding tape 271, the winding tape 271 pulls the closing plate 28. After the closing plate 28 is pulled, it moves towards the end closer to the equipment body 1. During this process, since the rectangular groove 11 and the connecting rod 12 are inclined, and in the initial state, the connecting hole 281 and the insertion slot are in an overlapping state, when the operator inserts the wire into the slot 244 on the conductive post 24, the operator first inserts the wire... The wire is inserted into the connection hole 281, and then into the wire insertion slot 22. The wire then enters the slot 244 on the conductive post 24 through the wire insertion slot 22. The operator then rotates the knob 233, which drives the gear disk 232 to rotate. The gear disk 232 drives the two gear rings 231 on the two mounting posts 23 to rotate. As the two mounting posts 23 rotate, the conductive post 24 rotates to wind up the wire. During this process, the mounting posts 23 drive the winding reel 27 to wind up the winding tape 271. The winding tape 271 pulls the closing plate 28. Connecting rod 1... 2. The sealing plate 28 slides within the rectangular groove 11, causing it to approach the device body 1. Initially, the connecting hole 281 and the wiring slot 22 overlap. As the sealing plate 28 approaches the device body 1, it moves along the inclined direction of the rectangular groove 11, causing it to tilt towards the device body 1. During this process, the connecting hole 281 and the wiring slot 22 no longer overlap until the sealing plate 28 contacts the device body 1. At this point, the connecting hole 281 and the wiring slot 22 no longer contact or overlap, allowing the sealing plate 28 to cover and seal the wiring slot 22, thereby achieving security of the interior of the device body 1. The mounting groove 21 is sealed, and the sealing plate 28 is closed to the wiring groove 22. At this time, the wiring between the wiring groove 22 and the connection hole 281 is in close contact with the outer wall of the equipment body 1 and the inner wall of the sealing plate 28, so that the wiring is tightly fixed between the sealing plate 28 and the equipment body 1, thereby preventing the wiring from coming off the mounting groove 21. At the same time, the sealing plate 28 squeezes the annular rubber ring, causing the annular rubber ring to deform, thereby achieving tight contact between the inner wall of the annular rubber ring and the wiring at the wiring groove 22, achieving sealing and fixing of the wiring, further preventing the wiring from coming off the mounting groove 21. Furthermore, by creating a groove 282 at one end of the sealing plate 28 near the equipment body 1, with the width of the groove 282 being the same as the outer diameter of the annular rubber strip 13, when the sealing plate 28 contacts the equipment body 1, the annular rubber ring on the equipment body 1 will enter the interior of the groove 282. At this time, after the annular rubber ring enters the interior of the groove 282, the wiring bends from below the annular rubber ring, and the wiring is located inside the groove 282. Subsequently, the wiring extends out from the groove 282, and the extended wiring contacts the outer wall of the body. At the same time, the extended wiring contacts the end of the sealing plate 28 near the equipment body 1, causing the wiring to be squeezed. Subsequently, the wiring extends out from the connection hole 281. During the process, the wiring is fixed and squeezed by the equipment body 1 and the sealing plate 28. On the other hand, the annular rubber strip 13 is located inside the groove 282, thus sealing the interior of the equipment body 1 and preventing external dust and impurities from entering the interior of the mounting groove 21.
