Description

Technical Field

[0001] This utility model relates to the field of repeater components, and in particular to a repeater. Background Technology

[0002] In the State Grid's Ring Main Unit (RMU) system, data repeaters are critical data forwarding and communication enhancement devices used to achieve distribution automation (DA) or feeder automation (FA). They act as a "communication bridge" in the smart distribution network, ensuring stable and reliable data exchange between terminal equipment (such as DTUs and FTUs) within the RMU and the master station system (such as the distribution automation master station and SCADA system). Therefore, ensuring the normal operation of the data repeaters is crucial to the overall system's normal functioning.

[0003] Existing technology uses bolts and disposable clips to fix the repeater in the working area. The position of the repeater is fixed and cannot be adjusted or changed according to the scenario, which is very inconvenient to use. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a repeater that can quickly realize the detachable operation of the repeater, thereby quickly completing the position adjustment of the repeater body.

[0005] Based on this, the present invention provides a repeater, which includes:

[0006] Repeater body;

[0007] A connecting plate is fixedly connected to the repeater body, and the edge of the connecting plate is provided with several positioning grooves;

[0008] The base has several positioning posts, each corresponding to a positioning slot. Each positioning post can be detachably inserted into a positioning slot.

[0009] The base has at least two mounting holes arranged sequentially along its edge.

[0010] The base is also provided with a limiting post, and a limiting block is sleeved on the upper part of the limiting post. The connecting plate is provided with a clearance hole that matches the cross-sectional shape of the limiting block.

[0011] A rotating block, wherein the rotating block is provided with mounting holes that match the cross-sectional shape of the limiting block;

[0012] The limiting block passes through the clearance hole, and the mounting hole of the rotating block passes through the limiting block and can rotate around the limiting post, so that the rotating block stops between the connecting plate and the limiting block.

[0013] In some embodiments of this application, four mounting holes are provided, and the four mounting holes are respectively located around the base.

[0014] In some embodiments of this application, the positioning groove has an opening along the edge of the connecting plate.

[0015] In some embodiments of this application, the limiting post is further provided with a limiting piece, which is located between the base and the limiting block.

[0016] In some embodiments of this application, the top of the repeater body is provided with a receiving antenna for wireless data transmission.

[0017] In some embodiments of this application, the bottom of the repeater body is provided with an optical fiber connection port for wired optical fiber reception.

[0018] Some embodiments of this application also include:

[0019] A first mounting plate is disposed on the base and connected to a second mounting plate via a connecting post. The first mounting plate has a first protective seat on the side facing the second mounting plate, and the second mounting plate has a second protective seat on the side facing the first mounting plate. The first protective seat cooperates with the second protective seat to clamp the optical fiber.

[0020] In some embodiments of this application, the first protective seat and the second protective seat are provided with protective pads.

[0021] In some embodiments of this application, the first protective seat is provided with mounting grooves on both sides, and the second protective seat is provided with mounting blocks on both sides that match the mounting grooves.

[0022] In some embodiments of this application, a locking piece is rotatably connected to one end of the connecting post near the second mounting plate. The locking piece is elliptical in shape, and the second mounting plate is provided with a locking hole that matches the cross-sectional shape of the locking piece.

[0023] This utility model provides a repeater, which has the following advantages compared with the prior art:

[0024] This utility model provides a repeater, which includes a repeater body, a connecting plate and a base for connecting the repeater body. The connecting plate is fixedly connected to the repeater body and has a plurality of positioning grooves on its edge away from the repeater body. The base has a plurality of positioning posts corresponding one-to-one with the positioning grooves. The positioning posts are detachably snapped into the positioning grooves. At least two mounting holes are sequentially provided on the edge of the base. The base also has a limiting post, on which a limiting block is fitted. The connecting plate has a clearance hole that matches the cross-sectional shape of the limiting block. A rotating block is provided on the side of the connecting plate facing away from the base. The rotating block has an assembly hole that matches the cross-sectional shape of the limiting block. The limiting block passes through the clearance hole. The rotating block is fitted onto the limiting post and the assembly hole passes through the limiting block. The rotating block can rotate around the limiting post after the assembly hole passes through the limiting block, thereby stopping the rotating block between the connecting plate and the limiting block.

[0025] Based on the above structure, during use, the base is placed on the workbench to be assembled. The base provides an assembly foundation for the repeater body and enables initial positioning of the repeater body. The base has positioning posts, and the edge of the connecting plate of the repeater body has positioning grooves that match the positioning posts. When the repeater body approaches the base, the positioning posts can be detachably engaged in the positioning grooves, achieving further positioning of the repeater body. Furthermore, the base also has limiting posts with limiting blocks fitted on them. The connecting plate has clearance holes that match the cross-sectional shape of the limiting blocks. A rotating block is located on the side of the connecting plate facing away from the base, and the rotating block has assembly holes that match the cross-sectional shape of the limiting blocks. Assembly of the repeater body is then required. When the limiting block on the limiting post passes through the clearance hole, the rotating block is then fitted onto the limiting post after the limiting block passes through the clearance hole, so that the assembly hole passes through the limiting block. At this time, the limiting block is located above the rotating block. By continuing to rotate the rotating block around the limiting post, the limiting block and the assembly hole can be misaligned, thereby causing the rotating block to stop between the limiting block and the connecting plate. The mutual abutment between the rotating block and the limiting block achieves the relative fixation of the connecting plate and the base, thus realizing the assembly operation of the repeater body and fixing the repeater body on the base. When it is necessary to remove the repeater body, simply rotate the rotating block around the limiting post again so that the assembly hole of the rotating block aligns with the limiting block, and the rotating block can be removed from the limiting post, thus realizing the disassembly operation of the repeater body. Thus, this application achieves the positioning operation of the repeater body assembly by setting a base and positioning columns, and realizes the detachable connection between the base and the repeater body by setting limit columns, limit blocks and other structures, which can effectively realize the change of the assembly position of the repeater body; the base has a simple and reliable structural design, which makes it easy to assemble and maintain the repeater body, and greatly reduces the assembly difficulty of the repeater.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0034] Specifically, such as Figures 1 to 5As shown, this utility model embodiment provides a repeater, which includes a repeater body 1, a connecting plate 4 for connecting the repeater body 1, and a base 8. The connecting plate 4 is fixedly connected to the repeater body 1 and has a plurality of positioning grooves 5 on its edge away from the repeater body 1. The base 8 has a plurality of positioning posts 10 corresponding one-to-one with the positioning grooves 5, and the positioning posts 10 can be detachably inserted into the positioning grooves 5. Further, at least two mounting holes 9 are sequentially provided on the edge of the base 8, and connectors are provided in the mounting holes 9 to fix the base 8 in the assembly area. The base 8 is also provided with a limiting post 11, and a limiting block 12 is fitted on the limiting post 11. The connecting plate 4 is provided with a clearance hole that matches the cross-sectional shape of the limiting block 12. A rotating block 6 is provided on the side of the connecting plate 4 facing away from the base 8. The rotating block 6 is provided with an assembly hole 7 that matches the cross-sectional shape of the limiting block 12. The limiting block 12 passes through the clearance hole. The rotating block 6 is fitted in the limiting post 11 and the assembly hole 7 passes through the limiting block 11. The rotating block 6 can rotate around the limiting post 11 after the assembly hole 7 passes through the limiting block 12, thereby stopping the rotating block 6 between the connecting plate 4 and the limiting block 12.

[0035] Based on the above structure, during use, the base 8 is placed on the area to be assembled. The base 8 provides an assembly foundation for the repeater body 1 and enables the initial positioning of the repeater body 1 during assembly. The base 8 is equipped with positioning posts 10, and the edge of the connecting plate 4 of the repeater body 1 has positioning grooves 5 that match the positioning posts 10. When the repeater body 1 approaches the base 8, the positioning posts 10 can be detachably inserted into the positioning grooves 5, achieving further positioning of the repeater body 1. Furthermore, the base 8 is also equipped with limiting posts 11, with limiting blocks 12 fitted on the limiting posts 11. The connecting plate 4 has clearance holes that match the cross-sectional shape of the limiting blocks 12. A rotating block 6 is located on the side of the connecting plate 4 facing away from the base 8, and the rotating block 6 has assembly holes 7 that match the cross-sectional shape of the limiting blocks 12. When assembling the repeater body 1, the limiting posts... The limiting block 12 on the 11 passes through the clearance hole, and the rotating block 6 is fitted onto the limiting post 11 after the limiting block 12 passes through the clearance hole, so that the assembly hole 7 passes through the limiting block 12. At this time, the limiting block 12 is located above the rotating block 6. By continuing to rotate the rotating block 6 around the limiting post 11, the limiting block 12 and the assembly hole 7 can be misaligned, so that the rotating block 6 stops between the limiting block 12 and the connecting plate 4. The mutual abutment between the rotating block 6 and the limiting block 12 realizes the relative fixation of the connecting plate 4 and the base 8, thereby realizing the assembly operation of the repeater body 1 and fixing the repeater body 1 on the base 8. When it is necessary to remove the repeater body 1, simply rotate the rotating block 6 around the limiting post 11 again so that the assembly hole 7 of the rotating block 6 corresponds to the limiting block 12, so that the rotating block 6 can be removed from the limiting post 11, thus realizing the disassembly operation of the repeater body 1. Thus, this application achieves the positioning operation of the repeater body 1 by setting the base 8 and positioning column 10, and realizes the detachable connection between the base 8 and the repeater body 1 by setting the limiting column 11, limiting block 12 and other structures, which can effectively realize the change of the assembly position of the repeater body 1; the structural design of the base 8 is simple and reliable, and it is easy to assemble and repair the repeater body 1, greatly reducing the assembly difficulty of the repeater.

[0036] It should be noted that, in order to achieve effective assembly of the repeater body 1 and the base 8, at least two limiting posts 11 are provided. The at least two limiting posts 11 are divided into two groups and respectively set on both sides of the repeater body 1 to ensure effective fixation of the repeater body 1. Correspondingly, the setting of the limiting block 12, the rotating block 6, the clearance hole, the assembly hole 7, etc., also corresponds one-to-one with the setting of the limiting posts 11.

[0037] like Figure 1 As shown, in a specific embodiment of this utility model, there are four mounting holes 9, which are located at the four corners of the base 8, and the connecting parts are preferably expansion bolts.

[0038] Optionally, in some embodiments of this application, the positioning groove 5 has an opening along the edge of the connecting plate 4. Based on the above structure, the opening allows the positioning post 10 to be more easily inserted into the positioning groove 1, thereby achieving rapid assembly of the repeater body.

[0039] Furthermore, the inner wall of the positioning groove 5 is provided with an arc-shaped chamfer. Based on the above structure, the arc-shaped chamfer can reduce the friction between the positioning post 10 and the positioning groove 5, and improve the connection effect between the positioning post 10 and the positioning groove 5.

[0040] Furthermore, in some embodiments of this application, the limiting post 11 is also provided with a limiting piece 13, which is located between the base 8 and the limiting block 12. When the repeater body 1 approaches the base 8, the limiting post 11 and the limiting block 12 enter the clearance hole and the assembly hole 7. At this time, the limiting piece 13 can abut against the connecting plate 4 to prevent the repeater body 1 from approaching the base 8 further. At the same time, the limiting piece 13 can also cooperate with the limiting block 12 to restrict the repeater body 1 when the limiting block 12 abuts against the rotating block 6, thereby strengthening the fixing effect of the repeater body 1.

[0041] Optionally, in some embodiments of this application, the top of the repeater body 1 is provided with a receiving antenna 2 for wireless data transmission, and the bottom of the repeater body 1 is provided with a fiber optic connector 3 for wired fiber optic reception. Based on the above structure, the repeater body 1 realizes wireless data transmission by setting the receiving antenna 2, and realizes wired data transmission by setting the fiber optic connector 3 to connect to a wired fiber optic cable. Wireless transmission and wired transmission can cooperate with each other to improve the data transmission effect.

[0042] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the repeater of this application also includes a first mounting plate 14 disposed on the base 8. The first mounting plate 14 is connected to a second mounting plate 15 via a connecting post 21. A first protective seat 16 is provided on the side of the first mounting plate 14 facing the second mounting plate 15, and a second protective seat 18 is provided on the side of the second mounting plate 15 facing the first mounting plate 14. The first protective seat 16 and the second protective seat 18 clamp the optical fiber. Furthermore, the first protective seat 16 and the second protective seat 18 are provided with protective pads 20 made of rubber material.

[0043] Based on the above structure, after the wired optical fiber is installed, the operator can continue to set the first mounting plate 14 on the base 8 and set the second mounting plate 15 on the first mounting plate 14 through the connecting post 21. The first protective seat 16 on the first mounting plate 14 and the second protective seat 18 on the second mounting plate 15 are set opposite to each other, which can clamp the wired optical fiber and prevent the wired optical fiber from shaking in strong winds and thus causing it to detach from the optical fiber connector 3.

[0044] Furthermore, the top edges of the first protective base 16 and the second protective base 18 are provided with arc-shaped chamfers. The arc-shaped chamfers can prevent the wired optical fiber from being damaged due to repeated friction between the wired optical fiber and the first protective base 16 and the second protective base 18.

[0045] Optionally, in some embodiments of this application, the first protective seat 16 is provided with mounting grooves 17 on both sides, and the second protective seat 18 is provided with mounting blocks 19 on both sides that match the mounting grooves 17. When the second protective seat 18 approaches the first protective seat 16, the mounting blocks 19 are inserted into the mounting grooves 17 to achieve quick positioning and assembly of the first protective seat 16 and the second protective seat 18. At the same time, in order to avoid damage to the mounting grooves 17 by the insertion of the mounting blocks 19, the top of the mounting blocks 19 is provided with a chamfer.

[0046] Furthermore, such as Figure 5 As shown, in some embodiments of this application, a locking piece 22 is rotatably connected to one end of the connecting post 21 near the second mounting plate 15. In this application, the locking piece is threadedly connected to the connecting post. More specifically, the locking piece 22 is elliptical, and the second mounting plate 15 is provided with an elliptical locking hole 23 that matches the cross-sectional shape of the locking piece 22. Similar to the rotating block 6 and the limiting block 12, when the second mounting plate 15 needs to be assembled, the locking piece 22 is rotated to align with the locking hole 23. At this time, the second mounting plate 15 can move along the connecting post 21 close to the first mounting plate 14 so that the locking piece 22 passes through the locking hole 23. After the locking piece 22 passes through the locking hole 23, the locking piece 22 is rotated so that the locking piece 22 abuts against the second mounting plate 15 and thus blocks the second mounting plate 15, thereby realizing the assembly operation of the second mounting plate 15.

[0047] In addition, the repeater body 1 of this application is also equipped with a repeater switching mechanism for wireless and wired switching. The repeater switching mechanism can assist the receiving antenna 2 and the fiber optic connector 3 in realizing wireless and wired data conversion, ensuring stable data transmission and preventing signal instability due to excessive distance. Specifically, the repeater switching mechanism includes an optical signal interface module, a wireless communication module, a main control processing module, and a local switching module. The optical signal interface module is electrically connected to the fiber optic connector 3 and connects to the core network through the fiber optic link to receive and transmit optical signals and perform photoelectric conversion. The wireless communication module is electrically connected to the receiving antenna 2 and establishes a wireless connection through the upstream core network of the cellular network. The main control processing module is coupled to the optical signal interface module and the wireless communication module to perform link status monitoring, routing policy management, and fault switching control. The local switching module provides one or more Ethernet ports and wireless access points for connecting downstream local terminal equipment.

[0048] In summary, this utility model provides a repeater comprising a repeater body, a connecting plate, and a base. The connecting plate is fixedly connected to the repeater body and has a positioning groove on its edge. The base has positioning posts corresponding to the positioning grooves, and mounting holes are sequentially provided along the edge of the base, with connectors installed within the mounting holes. The base also has limiting posts, with limiting blocks fitted onto the limiting posts. The connecting plate has clearance holes matching the shape of the limiting blocks. A rotating block is rotatably connected to the side of the connecting plate facing away from the base. The rotating block has assembly holes matching the shape of the limiting blocks. The limiting blocks can pass through the clearance holes and assembly holes, thereby engaging the base and the connecting plate via the rotating block. Compared with the prior art, the repeater body and base of this application are detachably connected, enabling positional changes of the repeater body. The base has a simple and reliable structural design, facilitating the assembly and maintenance of the repeater body and significantly reducing the assembly difficulty of the repeater.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
