[0002] The low-voltage distribution network feeder monitoring device generally includes a communication unit, multiple power modules and multiple low-voltage monitoring units, which can simultaneously monitor the electrical quantities, state quantities and operating environment quantities of multiple low-voltage circuits. Among them, the power module needs to be connected to the A, B, C three-phase circuits and the grounding circuit at the same time, and display in real time through the indicator light. Under special circumstances, the power module needs to be turned on and off by a switch. Since the above-mentioned power module needs to plug and unplug the power cord, the conventional method of fixing the power cord with screws will cause many inconveniences during use. Therefore, it is necessary to set a plug-in structure for connecting the power cord. When the conventional plug-in structure is used, it needs to have a certain damping effect to avoid the problem of the power cord loosening when the equipment is in use. Utility Model Content

[0003] In order to solve the problem that the power module of the above-mentioned low-voltage distribution network feeder monitoring device lacks a suitable power cord plug-in structure, the utility model provides a wiring structure of the power module of the low-voltage distribution network feeder monitoring device.

[0004] The technical solution of this utility model is as follows:

[0007] The power terminal block includes a first plug block and a second plug block for fixing the power line. The first plug block and the second plug block after being combined and connected can be inserted into the plug interface. A limiting plug block is provided on the side of the second plug block away from the first plug block, and the limiting plug block can be inserted into the limiting opening.

[0008] The power cord is fixed by the first plug block and the second plug block, and then a damping connection is performed by the limit plug block in conjunction with the limit opening. The above structure can be used to connect the power cord while preventing the power cord from loosening, ensuring that the power cord can be separated only after a pulling force is applied.

[0009] The specific structure of the above-mentioned limit plug block is that the limit plug block includes a connecting plate fixed to the second plug block, a bendable pressing block is arranged on the side of the connecting plate away from the second plug block, and an elastic pad is arranged between the pressing block and the connecting plate. The pressing block cannot be inserted into the limit opening under the support of the elastic pad, so it is necessary to manually press the pressing block and insert it into the limit opening, and then the interface supports the pressing block under the action of the elastic pad and contacts the inner wall of the limit opening, thereby realizing a damping connection.

[0010] As a preferred solution, the pressing block can be inserted into the limiting opening after compressing the elastic pad.

[0011] In order to obtain a better damping effect, the limiting openings are provided in plurality, and the pressing blocks are provided in plurality corresponding to the limiting openings.

[0012] As a preferred solution, the two ends of the elastic pad are extended relative to the pressing block. After a period of use, the elastic pad can be fully utilized by switching the position of the elastic pad.

[0013] In order to avoid replacing the power terminal structure, the elastic pad can be replaced. After the fixing effect becomes worse due to long-term use, the elastic pad can be replaced to make it have a better fixing effect again.

[0015] In order to facilitate fixing of the power cord, adjacent surfaces of the first plug block and the second plug block are provided with grooves, and the grooves are used to arrange the power cord.

[0016] As a preferred solution, a plug connector is connected to the outer shell of the power cord, and the plug connector is arranged in the groove and cannot move relative to the groove, so as to avoid the power cord from being misplaced.

[0017] The above-mentioned sockets are arranged in such a manner that the sockets include four sockets, namely, sockets A, B, C, and N.

[0018] The beneficial effect of the utility model is that the utility model is a wiring structure of a power module of a low-voltage distribution network feeder monitoring device. Different from the existing method of fixing the power cord with screws, the power cord is arranged and fixed by setting a power wiring terminal. After arrangement and fixation, the power wiring port of the plug port can be arranged correspondingly, so the power cord can be plugged in and fixed, which is convenient for separation. In order to prevent the power cord from loosening, the power wiring terminal also includes a limiting plug block structure, which can achieve plug-in fixation in conjunction with the limiting port structure, and can also use an elastic pad to achieve a damping connection.

[0028] like Figure 1 As shown, the low-voltage distribution network feeder monitoring device mainly includes a low-voltage communication unit, a power module and a low-voltage monitoring module, wherein the power module needs to be connected to the power cord and the power connection status is displayed through an indicator light. Under special circumstances, the power module can also be powered off. In order to avoid the need to loosen and tighten the screws of the power cord every time the plug-in board is plugged in, the above-mentioned power module is generally connected by plug-in.

[0029] like Figure 2-5 A wiring structure of a power module of a low-voltage distribution network feeder monitoring device is shown, comprising: Figure 2 The power connection port 1 of the power module is shown as well as Figure 3-5 The power connection terminal 3 shown is connected to the power line 4, and the power connection terminal 3 can be inserted into the power connection port 1, and the power line can be connected after the insertion.

[0030] And in the above structure, if Figure 2As shown, the power connection port 1 includes a plug port 12, and the plug port 12 is provided with multiple plug ports 11 along the length direction. The plug ports 11 are used to connect the power cord, and a limiting hole 13 is provided on one side of the plug port 12. The limiting hole is used to provide a damping effect to prevent the power cord from loosening.

[0031] Correspondingly, the power terminal 3 includes a first plug block 31 and a second plug block 32 for fixing the power cord 4. The first plug block 31 and the second plug block 32 after being combined and connected can be inserted into the socket 12, and after being inserted into the socket 12, multiple power cords 4 can be respectively inserted into the socket 11. Afterwards, in order to obtain a damping effect, a limiting plug block 33 is provided on the side of the second plug block 32 away from the first plug block 31, and the limiting plug block 33 can be inserted into the limiting opening 13.

[0032] It should be noted that the above-mentioned sockets 11 are arranged in such a manner that the sockets 11 include four sockets 11 , namely A, B, C, and N sockets 11 .

[0033] like Figure 3 , 4 As shown, the assembly structure of the power terminal 3 is that the limit plug 33 is connected to the second plug 32 by a screw, and the screw does not penetrate the first plug 31, so as to avoid the situation that the first plug 31 and the second plug 32 need to be disassembled due to the replacement of the limit plug 33. Therefore, in actual application, it can be more convenient, and only the screw fixing the limit plug 33 needs to be loosened, and the screw is vertically arranged and inserted into the second plug 32 from one end of the limit plug 33.

[0034] Correspondingly, the second plug block 32 is connected to the first plug block 31 by screws, and the above-mentioned screws also do not penetrate the limit plug block 33. When in use, it can avoid the situation where the limit plug block 33 needs to be disassembled due to replacing the power cord. In order to avoid the limit plug block 33 from being damaged due to lateral force, the side of the first plug block 31 away from the second plug block 32 is non-planar, and can be wavy or other shapes, to ensure that after being inserted into the plug interface 12, it cannot move in the direction perpendicular to the plug line.

[0035] In the above structure, in order to facilitate the fixing of the power cord 4, the adjacent surfaces of the first plug block 31 and the second plug block 32 are provided with grooves, and the grooves are used to set the power cord 4. As a preferred solution, the outer shell of the power cord 4 is connected with a plug connector 5, and the plug connector 5 is set in the groove, and the plug connector 5 cannot move relative to the groove. The misalignment of the power cord 4 can be avoided. The plug connector 5 is directly sleeved on the outer side of the power cord 4 and fixed to the power cord 4. After the plug connector 5 is fixed, the power cord 4 cannot move, and the fixation is completed. After the plug connector 4 is positioned, one end of the power cord 4 can be extended to a fixed length, so it is convenient to connect with the socket 11, so it is more convenient to use.

[0036] Finally, if Figure 3 , 4 As shown in Figures 5 and 6, the key point of this patent is that the specific structure of the above-mentioned limit plug 33 is that the limit plug 33 includes a connecting plate fixed to the second plug 32, and a bendable pressing block is provided on the side of the connecting plate away from the second plug 32. When the pressing block is pressed, it can be inserted into the limit opening 13. However, due to the large distance between the pressing block and the connecting plate, the two will be broken, and the small distance between the two will cause the plug-in structure to loosen. Therefore, the best choice is:

[0037] An elastic pad 34 is provided between the pressing block and the connecting plate. The pressing block cannot be inserted into the limiting opening 13 under the support of the elastic pad 34, so it is necessary to manually press and insert the pressing block into the limiting opening 13, and then the interface supports the pressing block and contacts the inner wall of the limiting opening 13 under the action of the elastic pad 34, thereby achieving a damping connection. At the same time, the pressing block can be inserted into the limiting opening 13 after compressing the elastic pad 34. By providing the elastic pad 34, the breaking of the pressing block can be avoided, and the above-mentioned fastening effect can be achieved through the elastic force of the elastic pad 34.

[0038] In the above structure, in order to obtain a better damping effect, a plurality of the limiting openings 13 are provided, a plurality of the pressing blocks are provided corresponding to the limiting openings 13 , and the plurality of pressing blocks share one elastic pad 34 .

[0039] Since the elastic pad 34 is prone to a problem of reduced elasticity after repeated use, as a preferred solution, the two ends of the elastic pad 34 are extended relative to the pressing block. After a period of use, the elastic pad 34 can be fully utilized by switching the position of the elastic pad 34, such as Figure 3 to Figure 4 state switch.

[0040] Furthermore, based on the above structure, in order to avoid replacing the power terminal 3 structure, the elastic pad 34 can be replaced. After long-term use, the fixing effect becomes poor, and the elastic pad 34 can be replaced to make it have a better fixing effect again. Therefore, when a single component has a problem, it can be directly replaced.

[0041] The above structure can be used to fix the power cord 4 through the first plug block 31 and the second plug block 32, and then the limiting plug block 33 cooperates with the limiting opening 13 to perform a damping connection. The above structure can be used to connect the power cord 4 while preventing the power cord 4 from loosening, ensuring that the power cord 4 can be separated only after a pulling force is applied.
