Description

Technical Field

[0001] This invention relates to the field of smart terminal technology, and in particular to a smart converged terminal for edge IoT stations. Background Technology

[0002] As the name suggests, the edge IoT smart converged terminal for power distribution areas integrates edge computing and IoT capabilities into devices in power distribution areas (areas where power grid equipment is concentrated) to achieve intelligent data fusion and processing. It is a "smart box" deployed in the power distribution area that integrates computing, communication and sensing capabilities. It can collect, process and analyze data from various electrical devices (such as circuit breakers, transformers, meters, etc.) in the area nearby, and can control these devices in a coordinated manner, thereby achieving more efficient, safer and smarter power grid operation.

[0003] In complex terrain or high-traffic areas, the external terminal blocks of smart converged terminals often need to be extended and exposed to the external environment due to on-site wiring requirements. These exposed terminal blocks are susceptible to corrosion from environmental factors such as moisture and dust, and also face physical risks such as accidental contact by personnel and collisions with equipment. This may lead to loosening or even breakage of the connection between the terminal block and the components. Existing connection solutions generally lack reliable mechanical fixing and protective design, making it difficult to withstand the above impacts. This can lead to connection failure between the terminal block and the terminal equipment, causing data acquisition interruption, communication abnormalities, and control function failures, which seriously affect the stable operation of smart converged terminals in the distribution area. Summary of the Invention

[0004] In view of the problems existing in the current edge IoT intelligent converged terminal, the present invention proposes an edge IoT intelligent converged terminal to solve these problems.

[0006] As a preferred embodiment of the edge IoT smart converged terminal of the present invention, the terminal body has an installation groove that matches the position and size of the fixing component, a spring is located between the installation groove and the top of the receiving component, movable grooves for accommodating the fixing component are provided on both sides of the lower part of the terminal body, and a slot is provided at the lower end of the terminal body.

[0007] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, the fixing component one includes four sets of ring-shaped fixed guard plates, a sliding groove between every two sets of fixed guard plates, a guide block one disposed on one side of the top of the fixed guard plate, a guide block two disposed on the other side of the top of the fixed guard plate, and a slot between the guide block one and the guide block two.

[0008] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, the pushing component includes a pushing assembly slidably connected between four sets of fixed guard plates, a push rod disposed at one end of the pushing assembly and extending through to the lower outer side of the fixing member, and a top plate disposed at the end of the push rod and extending the outer end of the top plate into the slot.

[0009] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, the pushing component includes a sleeve located between four sets of fixed protective plates, multiple sets of limiting teeth opened on the outer edge of the top of the sleeve, and four sets of limiting blocks disposed on the outer side of the sleeve, wherein the four sets of limiting blocks are correspondingly slidably connected in four sets of sliding grooves.

[0010] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, the receiving component includes a receiving block located at the top of the pushing component, a limiting shaft disposed on one side of the receiving block and extending into the pushing component, and four sets of guide blocks disposed on the outside of the receiving block, with the four sets of guide blocks correspondingly slidably connected in four sets of sliding grooves.

[0011] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, the receiving component further includes a rotating groove formed at the outer end of the receiving block, a collar sleeved on the rotating groove, and two sets of fixed shafts symmetrically arranged on the collar.

[0012] As a preferred embodiment of the edge IoT smart fusion terminal of the present invention, wherein: the two fixing members are arranged in pairs on both sides of the receiving block, and each pair of fixing members is symmetrical in the vertical direction with the fixing axis as the axis, and each pair of fixing members is staggered in the horizontal direction and a rotating shaft is arranged between the two pairs of fixing members in the horizontal direction.

[0013] As a preferred embodiment of the edge IoT smart converged terminal of the present invention, the second fixing component includes a fixing component located in the movable groove, and a sliding component fixedly connected to the top of the fixing component, wherein the sliding component is fixedly connected to the top of the fixing component in an inclined manner.

When encountering external pulling force, vibration impact, or accidental contact by personnel, the protective unit can immediately trigger a multi-level locking mechanism to effectively counteract lateral and axial tension, preventing problems such as loosening or poor contact of the terminal block, thereby ensuring the stability of power signal transmission and ensuring the accuracy of data acquisition and the reliable execution of remote control commands. The protective unit features a user-friendly quick-installation design, utilizing a push-to-unlock button and guide rail structure to achieve a convenient "one-click operation" experience: during installation, simply insert the terminal block into the interface and press the locking button to complete the mechanical reinforcement; during disassembly, press the unlock button to release the clips. The entire process requires no special tools and can be completed by a single person within 3 seconds. This design not only significantly reduces the time cost of on-site construction but also reduces the risk of equipment damage due to improper operation. It is particularly suitable for application scenarios where equipment in the distribution area is frequently maintained and upgraded, effectively improving the operation and maintenance efficiency and reliability of terminal equipment.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Reference Figures 1 to 5 This invention includes an edge IoT smart fusion terminal, comprising a terminal body 1 and a protective unit 2. There are two sets of protective units 2, which are symmetrically arranged on both sides below the terminal body 1. The two sets of protective units 2 can respectively fix the two ends of the terminal block 3, thereby limiting the multi-position of the terminal block 3. Reference Figure 2 The protective unit 2 includes a fixing member 21 inside the terminal body 1, a pushing member 22 disposed inside the fixing member 21 with one end of the pushing member 22 extending through to the outside of the fixing member 21, a receiving member 23 disposed at the top of the pushing member 22, multiple sets of fixing members 24 disposed on both sides of the receiving member 23, and a spring 25 disposed at the top of the receiving member 23.

[0025] Referring to Figure 2, the terminal body 1 has a mounting groove 11 that matches the position and size of the fixing member 21. The spring 25 is located between the mounting groove 11 and the top of the receiving component 23. The lower sides of the terminal body 1 have movable grooves 12 that allow the fixing member 24 to move. The lower end of the terminal body 1 has a slot 13. The bottom end of the fixing member 21 does not abut against the top of the mounting groove 11, leaving a gap between them. The spring 25 is installed in this gap. The movable groove 12 provides space for the fixing member 24 to rotate and limits the range of motion of the fixing member 24 by its own size.

[0026] Reference Figure 3 The fixing component 21 includes four sets of annularly distributed fixing guard plates 211, a sliding groove 212 located between every two sets of fixing guard plates 211, a guide block 213 located on one side of the top of the fixing guard plate 211, a guide block 214 located on the other side of the top of the fixing guard plate 211, and a slot 215 located between the guide block 213 and the guide block 214. The outer wall of the fixing guard plate 211 is fixedly connected to the mounting groove 11, and the sliding groove 212 provides a track for the guide block 233 and the limiting block 226 to slide.

[0027] Furthermore, the top of guide block 1 213 is inclined toward the slide groove 212. Any part passing through the top of guide block 1 213 will be guided into the slide groove 212. The top of guide block 214 is inclined toward the slot 215. Therefore, any part passing through the top of guide block 214 will be guided into the slot 215 and ultimately be locked and limited by the slot 215.

[0028] Reference Figure 3 The pushing component 22 includes a pushing assembly 221 slidably connected between four sets of fixed guard plates 211, a push rod 222 disposed at one end of the pushing assembly 221 and extending through to the lower outer side of the fixing member 21, and a top plate 223 disposed at the end of the push rod 222 and extending the outer end of the top plate 223 into the slot 13. The pushing assembly 221 is fixedly connected to the push rod 222, and the top plate 223 is fixedly connected to the end of the push rod 222. The top plate 223 can slide within the slot 13. Through the fixed connection between the three, it can be seen that the three cannot move independently.

[0029] Reference Figure 3 The pushing component 221 includes a sleeve 224 located between four sets of fixed guard plates 211, multiple sets of limiting teeth 225 extended from the top of the sleeve 224, and four sets of limiting blocks 226 disposed on the outside of the sleeve 224. The four sets of limiting blocks 226 are slidably connected to the four sets of sliding grooves 212. The limiting blocks 226 are fixedly disposed on the outside of the sleeve 224. Therefore, the pushing component 221 will slide in the sliding grooves 212 via the limiting blocks 226, and will not rotate while sliding.

[0030] Reference Figure 3 The receiving component 23 includes a receiving block 231 located at the top of the pushing component 221, a limiting shaft 232 disposed on one side of the receiving block 231 and extending into the pushing component 221, and four sets of guide blocks 233 disposed on the outside of the receiving block 231, with the four sets of guide blocks 233 correspondingly slidably connected in four sets of slide grooves 212. The top of the guide block 233 has an inclined structure, and its inclined direction is opposite to that of the first guide block 213 and the second guide block 214. Therefore, the end of the guide block 233 can slide against the top of the first guide block 213 and the second guide block 214.

[0031] Reference Figure 3 The receiving component 23 also includes a rotating groove 235 opened at the outer end of the receiving block 231, a collar 236 sleeved on the rotating groove 235, and two sets of fixed shafts 234 symmetrically arranged on the collar 236. The cooperation between the collar 236 and the rotating groove 235 enables the fixed shafts 234 to only follow the vertical displacement when the receiving component 23 rotates and moves.

[0032] Combination Figure 4 and Figure 5 During use, while the guide block 233 is slidably connected within the groove 212, it will limit the entire receiving component 23, allowing it to slide within the groove 212 but not rotate. When slidably connected within the first fixing member 21, the end of the guide block 233 is inserted at half the side of the limiting tooth 225, but cannot be fully engaged within the limiting tooth 225. However, when the guide block 233 slides out of the groove 212, it will break free from its limitation and the end of the guide block 233 will be fully engaged within the limiting tooth 225. At this time, the entire receiving component 23 will undergo a slight angle change. When the angle-changed receiving component 23 moves towards the first fixing member 21, the end of the guide block 233 will adhere to the top oblique side of the first guide block 213 or the second guide block 214, and the contact method between the guide block 233 and the first guide block 213 and the second guide block 214 is an alternating contact.

[0033] Reference Figure 3 and Figure 4 The fixing parts 24 are arranged in pairs on both sides of the receiving block 231. Each pair of fixing parts 24 are symmetrical in the vertical direction with the fixing shaft 234 as the axis. Each pair of fixing parts 24 are staggered in the horizontal direction and symmetrically distributed in the horizontal direction. A rotating shaft 243 is arranged in the horizontal direction between each pair of fixing parts 244. The fixing parts 24 as a whole can rotate in relative directions in the movable groove 12 with the rotating shaft 243 as the axis.

[0034] Reference Figure 4The second fixing component 24 includes a fixing component 241 located in the movable groove 12, and a sliding component 242 fixedly connected to the top of the fixing component 241. The sliding component 242 is fixedly connected to the top of the fixing component 241 in an inclined manner. The four sets of fixing components 24 can form an inwardly converging mechanical claw structure. The four sets of fixing components 24 can hook and hold the four corners of the interface to prevent the interface from falling off.

[0035] Reference Figure 4 The fixing component 241 includes a fixing rod 244 located in the movable groove 12 and a fixing hook 245 disposed at the end of the fixing rod 244. The sliding component 242 includes a sliding rod 246 fixedly connected to the top of the fixing rod 244 and a sliding groove 247 opened in the sliding rod 246, and the fixing shaft 234 is slidably connected in the sliding groove 247. The sliding groove 247 can ensure that the fixing shaft 234 can normally push the fixing component 24 to rotate.

[0036] Combination Figure 2 , Figure 4 and Figure 5During use, the terminal block 3 is inserted into the slot 13. During insertion, both ends of the terminal block 3 abut against the top plates 223 of the two sets of protective units 2 located on both sides of the lower end of the terminal body 1, thereby pushing the top plates 223 to retract inward. The retracted top plates 223 will drive the pushing component 22 to move backward along the slide groove 212. The moving pushing component 22 will also push the receiving component 23 to compress the spring 25 backward. During this process, the moving receiving component 23 will push the fixing parts 24 on both sides to converge inward around the pivot 243. When terminal block 3 moves to the innermost side of slot 13 against top plate 223, pushing component 221 pushes receiving component 23 to the top of fixed guard plate 211, causing guide block 233 to disengage from slide groove 212. At this point, pushing terminal block 3 stops, and spring 25 rebounds, pushing receiving component 23 to move in the opposite direction. Guided by guide block 233 and guide block 214, the moving receiving component 23 moves downward a small distance and slides into slot 215, where it is limited. During this process, receiving component 23 is driven by fixed shaft 234. The two fixing components 241 on both sides of the moving part will completely converge at the opening of the slot 13, and the limiting teeth 225 at their ends are located outside the opening of the slot 13, fastening and gripping the outside of the terminal block 3. When the terminal block 3 is pulled externally, the fastening fixing component 24 will limit and fix it in the slot 13 through the fixing hook 245, thereby preventing the terminal block 3 from falling off due to external violent pulling. In summary, the present invention provides an integrated protective unit 2 at the insertion point of the terminal block 3 and the terminal body 1. This protective unit 2 uses mechanical buckling and elastic positioning. The structure achieves a dual locking function: on the one hand, it achieves rigid fixation through the interface of the terminal body 1 that matches the terminals of the terminal block 3; on the other hand, the built-in protection unit can provide a continuous inward clamping force when the terminal block is abnormally displaced. When it encounters external pulling force, vibration impact or accidental contact by personnel, the protection unit 2 can immediately trigger a multi-level locking mechanism to effectively offset the lateral and axial tension, prevent the terminal block 3 from loosening, poor contact and other problems, thereby ensuring the stability of power signal transmission and ensuring the accuracy of data acquisition and the reliable execution of remote control commands. Conversely, when it is necessary to remove terminal block 3, it is necessary to continue pressing terminal block 3 downwards. Terminal block 3 pushes top plate 223 to repeat the above operation. The difference is that when the receiving component 23 moves to the top of the fixing component 21, the guide block 233 disengages from the limit of the slot 215 and slides into the slide groove 212 under the guidance of the guide block 213. With the elastic support of the spring 25, the receiving component 23 pushes the pushing component 22 to extend outwards. The outwardly extending pushing component 22 pushes top plate 223 through push rod 222 to push terminal block 3 out of slot 13, and finally makes top plate 223 seal the opening of slot 13, which plays a role in sealing, dustproofing and waterproofing. At the same time, during the movement of the receiving component 23, due to the outward extension of the receiving component 23, the fixed shaft 234 pushes the sliding component 242 to drive the fixed component 241 around the rotating shaft 243 as the axis in the movable groove. 12 expands outward, thereby retracting the retaining element 24, which is gathered at the opening of slot 13 for limiting, to avoid obstructing the removal of terminal block 3. As explained above, when terminal block 3 needs to be removed, a specific operation is required to open it, thus avoiding the possibility of opening due to accidental factors and further ensuring safety. It adopts a user-friendly quick-installation design, which realizes the convenient experience of one-click operation through a press-type unlock button and guide rail structure: during installation, simply insert terminal block 3 into the interface and press the locking button to complete the mechanical reinforcement; during disassembly, press the unlock button to release the buckle. The whole process does not require special tools and can be completed by a single person in a short time. This design not only significantly reduces the time cost of on-site construction, but also reduces the risk of equipment damage caused by improper operation. It is particularly suitable for application scenarios where equipment in the distribution area is frequently maintained and upgraded, effectively improving the operation and maintenance efficiency and reliability of terminal equipment.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
