[0002] The signal access devices used in power line carrier construction mainly function to connect the carrier signal to the power line. These devices are usually used to superimpose data or control signals onto the power line to achieve remote control and data transmission. The types and functions of signal access devices depend on the specific application scenarios, such as power metering, smart home control or industrial automation. Their design needs to consider signal coupling efficiency, anti-interference ability and safety and reliability to ensure stable operation in complex power line environments. Chinese Patent CN217063755U discloses a wireless local area network (WLAN) access device with a powerline network interface, comprising a wireless signal transmitter, a power panel, a WLAN access box, and a power plug. The WLAN access box has a power panel on its side, a wireless signal transmitter and a data cable connector on its top, and a foldable power plug at its bottom. The WLAN access box features a centrally located power panel on its side, with a network cable interface for easy connection. A heat dissipation strip on the power panel enhances heat dissipation and ease of use. A retractable data cable connector is located on one side of the top of the WLAN access box, allowing for angle adjustment and convenient external wiring. Support feet are located at the bottom corner of the WLAN access box, and a foldable power plug is located at the center of the bottom.

[0003] Based on existing solutions and actual production and processing applications, existing power line carrier construction signal access devices are susceptible to physical impacts, collisions, or drops due to construction environment factors, which can lead to breakage or deformation, resulting in direct damage to internal circuit boards and components, and signal interruption. Therefore, we propose a power line carrier construction signal access device with protective functions to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a power line carrier construction signal access device with protection function, so as to solve the problem mentioned in the background art that the current power line carrier construction signal access device is easily damaged by physical bumps, impacts or drops due to the construction environment, which leads to direct damage to the internal circuit board and components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a signal access device for power line carrier construction with protection function, comprising a signal access unit: A collar is fixedly installed on the top of the lower end of the signal receiver, and a transparent cover is fitted and connected to the outside of the collar. A through groove is opened at the front end of the transparent cover at the connection of the signal receiver wiring harness. The size of the inner cavity of the transparent cover is the same as the size of the outer ring of the collar. Fixing components are provided at both ends of the transparent cover. A heat dissipation component is provided on the outside of the transparent cover, and a reinforcement component is provided at the front end of the transparent cover.

[0006] Preferably, the fixing component includes a fixing rod and a lead screw, and the lower ends of both the left and right ends of the transparent cover are slidably connected to the fixing rod. The middle position of the fixing rod is connected to the lead screw by a thread, and one end of the lead screw body is rotatably connected to the side wall of the transparent cover.

[0007] Preferably, the front and rear ends of the side wall of the collar are provided with positioning holes, the fixing rod is set in a "U" shaped structure, and the rod body of the fixing rod is engaged with the positioning hole.

[0008] Preferably, the heat dissipation component includes heat dissipation slots, mounting brackets, and cooling fans, and heat dissipation slots are fixedly installed at both ends of the transparent cover, and mounting brackets are fixedly installed at the rear end of the transparent cover, with cooling fans rotatably connected to both ends of the mounting brackets.

[0009] Preferably, the heat dissipation groove and the transparent cover are connected in a communication state, and the mounting bracket is also connected in a communication state with the transparent cover.

[0010] Preferably, the reinforcement component includes a slide bar, a clamping plate, and a spring, and slide bars are fixedly installed at both the left and right ends of the front end of the signal access device. The upper and lower ends of the slide bar are slidably connected to clamping plates, and a spring is sleeved and connected to the outer side of the slide bar, and the spring is connected to the clamping plate.

[0011] Preferably, the clamping plate is configured in a semi-arc shape, and screws are threaded to both ends of the upper clamping plate of the slide rod, and fixing blocks are fixedly installed at both ends of the lower clamping plate of the slide rod. The screw shafts are threaded to the fixing blocks.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: the signal access device for power line carrier construction with protective function can withstand accidental drops, collisions or impacts during construction through the cooperation between the collar and the transparent cover, thereby effectively protecting the internal precision circuit board and components. At the same time, the cooperation between the heat sink and the cooling fan can prevent frequency reduction and ensure that the carrier signal transmission power and signal processing speed are always kept at the rated optimal state. Then, the clamp can prevent the cable connector from being pulled out by direct impact, avoiding data loss or debugging failure due to sudden power failure or signal interruption. 1. By placing the transparent cover over the outside of the collar, the signal receiver is positioned inside the transparent cover. Then, by rotating the lead screw, which is connected to the fixed insertion rod via threads, and with one end of the lead screw rotatably connected to the side wall of the transparent cover, the lead screw causes the fixed insertion rod to extend and retract, engaging with the positioning hole on the collar. This secures the collar to the transparent cover, thus protecting the signal receiver. The fit between the collar and the transparent cover can withstand accidental drops, collisions, or impacts during construction, effectively protecting the delicate internal circuit boards and components, and ensuring the stability and continuity of the signal connection. 2. By connecting the mounting bracket to the transparent cover, two sets of cooling fans can dissipate heat from the signal receiver inside the transparent cover cavity. Simultaneously, by connecting two sets of heat dissipation slots to the transparent cover, the heat inside the transparent cover can be expelled through the cooperation between the cooling fans and the heat dissipation slots, thus cooling the signal receiver. The cooperation between the heat dissipation slots and the cooling fans can prevent frequency reduction and ensure that the carrier signal transmission power and signal processing speed are always maintained at the rated optimal state, thereby ensuring stable communication distance and transmission rate. 3. The spring force allows the clamping plates to slide on the slide rod, thus bringing the two sets of clamping plates together. By tightening the screws, the screw rods are connected to the fixing blocks through threads, thereby fixing the two sets of clamping plates together and securing the wire harness. The clamping plates prevent the cable connectors from being pulled out by direct impact, avoiding data loss or debugging failures caused by sudden power outages or signal interruptions, thus effectively reducing bit errors and communication interruptions.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In order to solve the technical problem that existing power line carrier construction signal access devices with protection functions are easily damaged by physical bumps, impacts or drops due to construction environment factors, which can lead to direct damage to internal circuit boards and components, this embodiment discloses the following technical content. Please see Figures 1-6 A signal access device for power line carrier construction with protective function includes a signal access device 1, a collar 2, a transparent cover 3, a positioning hole 4, a fixing rod 5, a screw 6, a heat dissipation groove 7, a mounting groove frame 8, a cooling fan 9, a slide rod 10, a clamping plate 11, a spring 12, a screw 13, and a fixing block 14. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using the signal receiver 1, a collar 2 is fixedly installed on the top of the lower end of the signal receiver 1, and positioning holes 4 are provided at both the front and rear ends of the side wall of the collar 2. Since the size of the inner cavity of the transparent cover 3 is the same as the size of the outer ring of the collar 2, the transparent cover 3 can be fitted onto the collar 2, thereby fitting the transparent cover 3 onto the outside of the signal receiver 1 and placing the signal receiver 1 inside the cavity of the transparent cover 3. Since the lower ends of both the left and right ends of the transparent cover 3 are slidably connected to fixing rods 5, and the fixing rods 5 are set in a "U"-shaped structure, and are fixed... A screw rod 6 is threadedly connected to the middle position of the fixed insertion rod 5, and one end of the screw rod 6 is rotatably connected to the side wall of the transparent cover 3, so that the screw rod 6 can be rotated. Thus, the rotation of the screw rod 6 can drive the fixed insertion rod 5 to extend and retract, and the rod of the fixed insertion rod 5 is inserted into the diameter of the positioning hole 4, so that the transparent cover 3 and the collar 2 are fixed together, thereby protecting the signal receiver 1. The cooperation between the collar 2 and the transparent cover 3 can withstand accidental drops, collisions or impacts during construction, thereby effectively protecting the internal precision circuit boards and components. like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when the signal receiver 1 is placed inside the transparent cover 3, a through slot is provided at the front end of the transparent cover 3 at the connection point of the signal receiver 1's wiring harness. Simultaneously, slide rods 10 are fixedly installed at both ends of the front end of the transparent cover 3, and clamping plates 11 are slidably connected to the upper and lower ends of the slide rods 10. A spring 12 is sleeved on the slide rod 10 and connected to the clamping plates 11. When the wiring harness is connected to the signal receiver 1, the clamping plates 11 are pulled to slide on the slide rods 10. As the clamping plates 11 slide, they compress the spring 12, allowing the wiring harness to pass through the through slot on the transparent cover 3 and connect to the signal receiver 1. Because the clamping plates 11 are semi-circular in shape, after the wiring harness is connected... After completion, the pull on the clamp 11 can be released, and the clamp 11 will be reset by the elastic force of the spring 12, so that the two clamps 11 are close to each other and the wire harness is placed between the two clamps 11. Because the left and right ends of the upper clamp 11 in the slide rod 10 are connected to the screws 13 by threads, and the left and right ends of the lower clamp 11 in the slide rod 10 are fixedly installed with fixing blocks 14, so that the screws 13 can be screwed, so that the rod of the screw 13 is connected to the fixing block 14 by threads, thereby fixing the two clamps 11 together and reinforcing the wire harness between the two clamps 11. The clamps 11 can prevent the cable connector from being pulled out by direct impact, and avoid data loss or debugging failure due to sudden power failure or signal interruption. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when the signal receiver 1 is in operation, heat dissipation slots 7 are fixedly installed on both the left and right ends of the transparent cover 3, and the heat dissipation slots 7 are connected to the transparent cover 3. A mounting bracket 8 is fixedly installed on the rear end of the transparent cover 3, and the mounting bracket 8 is also connected to the transparent cover 3. At the same time, cooling fans 9 are rotatably connected to both the left and right ends of the mounting bracket 8. When the signal receiver 1 is in operation, the heat can be dissipated through the heat dissipation slots 7. At the same time, the controller can control the operation of the two sets of cooling fans 9, so that the operation of the cooling fans 9 can dissipate heat from the signal receiver 1. The operation of the cooling fans 9 can also dissipate heat from the cavity of the transparent cover 3 through the heat dissipation slots 7. The cooperation between the heat dissipation slots 7 and the cooling fans 9 can prevent frequency reduction and ensure that the carrier signal transmission power and signal processing speed are always kept at the rated optimal state. The above completes a series of operations for the power line carrier signal access device with protection function.
