Description

Technical Field

[0001] This utility model relates to the technical field of smart energy meters, specifically to a smart energy meter with anti-tangle feature. Background Technology

[0002] As the core equipment for electricity metering, the stability of the cable connection at the terminal of the smart meter directly affects the metering accuracy and electricity safety.

[0003] The existing smart meters lack dedicated cable restraint structures at their terminals. Cables inside the meter box are mostly introduced into the smart meter terminals from a single direction. The physical space at the smart meter terminals is limited, and the terminals are arranged linearly and densely (4 ports for single-phase meters, 7 / 8 ports for three-phase meters), with only a few centimeters between adjacent ports. Cables are generally connected to the terminals in a staggered manner, and multiple cables are prone to crossing, tangling, and sticking together. Especially the cable sections near the terminals, due to the lack of fixing measures, the cables (especially hard-core cables with insulating sheaths) have a certain rigidity and are prone to shifting towards surrounding ports after bending. In addition, their own weight, external vibrations, and thermal expansion and contraction will cause the cables to sag under their own weight, resulting in the cables shifting downwards or laterally and tangling with the cables of other ports, forming a messy stack below the smart meter terminals.

[0004] The tangled cables make it difficult for maintenance personnel to distinguish between incoming and outgoing lines, making disassembly and repair cumbersome and increasing the risk of electric shock from accidental contact with exposed cables. Furthermore, the wiring terminals of existing smart meters are mostly fixed clamps, which are inconvenient to install and remove.

[0005] In addition, the heat from the tightly wrapped cables will accumulate, resulting in poor heat dissipation. The insulation layer is also prone to damage under high temperature and mutual friction, causing short circuits, tripping, or even electrical fires. Utility Model Content

[0006] Purpose of the utility model: To provide an anti-tangle smart energy meter to solve the above-mentioned problems existing in the prior art.

[0007] Technical solution: A smart energy meter with anti-winding function, comprising an energy meter body and an anti-winding component disposed on the wiring terminals of the energy meter body, wherein the anti-winding component includes: A U-shaped mounting bracket is configured on the wiring terminal of the main body of the electricity meter; the mounting bracket has a horizontal plate opposite to the wiring port of the main body of the electricity meter, the horizontal plate has a predetermined vertical distance from the wiring port of the main body of the electricity meter, the horizontal plate has two sets of wire holes, the two sets of wire holes are arranged at intervals along the width direction of the horizontal plate, and at least one set of wire holes is staggered from the wiring port along the width direction of the horizontal plate; Multiple cable securing units are arranged on the inner side of the horizontal plate and correspond to the corresponding cable passage holes; including cable securing tubes and cable clamps arranged at the ends of the cable securing tubes, the cable clamps having deformable clamping ends suitable for positioning the corresponding cables.

[0008] Furthermore, the anti-tangle assembly also includes multiple wire splitting units, which are disposed on the outer side of the horizontal plate and correspond to the corresponding wire passage holes; each wire splitting unit includes a bracket and a wire bundle tube disposed on the bracket, the wire bundle tube having an axial opening on its side wall, and the wire bundle tube having a predetermined toughness.

[0009] Furthermore, the cable clamp includes a guide ring, which is slidably disposed inside the cable fixing tube, and the guide ring and the cable fixing tube have a predetermined sliding damping value; two clamping arms, one end of which is fixed radially to the end wall of the guide ring, the inner side wall of the clamping arm forms an arc-shaped clamping working surface, and the outer side wall of the clamping arm gradually expands outward along the axial direction to the other end, and the two clamping arms form the clamping end of the cable clamp.

[0010] Furthermore, the two mounting arms of the mounting bracket are respectively rotatably configured with corresponding positions on both sides of the wiring terminal of the electricity meter body via a rotating shaft, and through holes are provided, which are suitable for locking with the corresponding positions of the electricity meter body by bolts.

[0011] Furthermore, the outer wall of the clamping arm is provided with blind holes.

[0012] Furthermore, the fixed conduit has multiple sliding grooves of predetermined length on the end sidewall near the horizontal plate, and the guide ring has a sliding block that is slidably adapted to the sliding groove on its ring wall.

[0013] Beneficial effects: (1) The horizontal plate of the mounting bracket is provided with two sets of wire holes arranged vertically and vertically and staggered with the wiring port. The wire harness tube is used for wire separation and constraint. Then the end of the cable passes through the corresponding wire hole of the horizontal plate and extends into the wire fixing unit inside the horizontal plate. The cables of adjacent wiring ports are respectively selected to pass through the staggered wire holes, so that the multiple cables connected to the wiring port are staggered and isolated, effectively avoiding the cables from crossing, tangling and sticking together, preventing short circuits caused by aging, softening or friction damage of the cable insulation layer, and reducing the heat accumulation caused by the cable sticking together, improving the heat dissipation effect of the wiring terminal and delaying the aging of the insulation layer.

[0014] (2) The cable fixing unit is configured on the inner side of the horizontal plate and corresponds to the cable hole. The elastic clamping end of the cable clamp can firmly position the cable. With the tightening and pressing of the screw at the connection port, the cable segment near the connection port is double fixed, ensuring the contact stability between the cable and the connection port.

[0015] (3) The cable clamp is slidably adapted to the sliding groove of the cable fixing tube through the guide ring. The blind hole on the outer wall of the clamp arm can be easily pulled out with the help of tools such as screwdrivers, so that the clamping end can loosen the cable, which is convenient for cable disassembly and rewiring during maintenance.

[0018] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0019] like Figure 1-5 The present invention relates to an anti-winding smart energy meter, which mainly includes an energy meter body 1 and an anti-winding assembly configured on the wiring terminals of the energy meter body 1. The anti-winding assembly includes a U-shaped mounting bracket 3 and multiple wire fixing units 2. U-shaped mounting bracket 3 is configured on the wiring terminal of the electricity meter body 1; the mounting bracket 3 has a horizontal plate 4 opposite to the wiring port 17 of the electricity meter body 1, the horizontal plate 4 and the wiring port 17 of the electricity meter body 1 have a predetermined vertical distance, the horizontal plate 4 has two sets of wire through holes 5, the two sets of wire through holes 5 are arranged at intervals along the width direction of the horizontal plate, at least one set of wire through holes 5 and the wiring port 17 are staggered along the width direction of the horizontal plate 4; the staggered arrangement of the wire through holes 5 and the wiring port 17 avoids the cross-entanglement of cables from the spatial layout, and combined with the dual constraints of the branching unit and the fixing unit 2, the orderly arrangement of cables is realized.

[0020] Multiple cable securing units 2 are arranged on the inner side of the horizontal plate 4 and correspond to the corresponding cable passage holes 5; including cable securing tubes 6 and cable clamps 7 disposed at the ends of cable securing tubes 6. The cable clamps 7 have deformable clamping ends suitable for positioning the corresponding cables. Specifically, the cable clamps 7 include guide rings 10 and two clamping arms 11.

[0021] The guide ring 10 is slidably disposed inside the cable fixing tube 6, and the guide ring 10 and the cable fixing tube 6 have a predetermined sliding damping value. The two clamping arms 11 are made of plastic or rubber material with a predetermined elastic deformation force. One end is fixed radially to the end wall of the guide ring 10. The inner side wall of the clamping arm 11 forms an arc-shaped clamping working surface, and the outer side wall of the clamping arm 11 gradually expands outward along the axial direction to the other end. The two clamping arms 11 form the clamping end of the cable clamp 7. When the clamping arms 11 come together, they form a cable passage. The cable passes through the clamping arms 11 and presses the cable clamp 7 into the cable fixing tube 6. The two clamping arms 11 of the cable clamp 7 come together and clamp the cable outside, fixing the cable inside the horizontal plate 4. In addition, the outer side wall of the clamping arm 11 is provided with a blind hole 14. When maintenance is required, the head of a screwdriver or other tool can be inserted into the blind hole 14 to allow the tool to pry the clamping arm 11 out of the cable fixing tube 6, and the two clamping arms 11 release the cable.

[0022] The outer wall of the clamping arm 11 is extended outward, and the clamping end is contracted by the compression of the inner wall of the cable fixing tube 6. Combined with the elastic deformation force of the clamping arm 11, it can achieve adaptive clamping of cables of different diameters without the need for additional adjustment.

[0023] In this embodiment, preferably, the fixing tube 6 has multiple sliding grooves 15 of predetermined length on the end side wall near the horizontal plate 4, and the guide ring 10 has a sliding block 16 on its ring wall that is slidably adapted to the sliding grooves 15. The sliding grooves 15 can be symmetrically opened, and the length of the sliding grooves 15 limits the sliding stroke of the guide ring 10. The sliding engagement between the guide ring 10 and the fixing tube 6 enables rapid switching between clamping and releasing.

[0024] In some preferred embodiments, the anti-tangle assembly further includes multiple wire splitting units, which are disposed on the outside of the cross plate 4 and correspond to the corresponding wire passage holes 5. The wire splitting unit includes a bracket 8 and a wire harness tube 9 disposed on the bracket. The wire harness tube 9 is made of rubber and has predetermined toughness and elasticity. The wire harness tube 9 has an opening along the axial direction on its side wall.

[0025] The cable management unit's cable tray 9 has an axial opening on its side wall, providing predetermined flexibility to quickly clamp cables of different diameters, enabling rapid cable separation and constraint. The cable management unit guides externally connected cables through the cable tray 9, ensuring an orderly arrangement of cables from the inlet to the cable pass-through hole 5. This further prevents cables from tangling outside the connector, making the wiring at the connector more standardized, facilitating quick identification of incoming and outgoing lines by maintenance personnel, and reducing the error rate during maintenance operations.

[0026] In some preferred embodiments, the two mounting arms of the mounting bracket 3 are respectively rotated and configured to be at corresponding positions on both sides of the wiring terminal of the electricity meter body 1 via the rotating shaft 12, and through holes are provided, which are suitable for locking to the corresponding positions of the electricity meter body 1 by bolts 13. The angle of the mounting bracket 3 can be adjusted according to the wiring operation requirements. After the wiring is completed, the mounting bracket 3 is locked by bolts 13, which makes the operation flexible.

[0027] In actual use, the mounting bracket 3 is rotated to a suitable angle via the pivot 12 so that there is enough space for wiring operations between the horizontal plate 4 and the wiring port 17, and the bolt 13 is not locked for the time being. The cables that need to be connected to the connection port 17 are respectively constrained by the cable bundle tube 9 of the splitting unit. Then, the cable ends are passed through the cable passage hole 5 of the horizontal plate 4 and extended into the cable fixing unit 2 inside the horizontal plate 4. The cables of adjacent connection ports 17 are respectively selected to pass through the cable passage hole 5 with staggered vertical alignment to achieve cable misalignment isolation. After the cable is threaded through, pass the end of the cable through the two clamping arms 11 of the cable clamp 7, press the guide ring 10 into the cable fixing tube 6, and slide the sliding block 16 along the sliding groove 15 into the cable fixing tube 6. Because the outer wall of the clamping arm 11 is an outwardly expanding structure, the clamping arms 11 are squeezed together by the inner wall of the cable fixing tube 6 during the pressing process, and the arc-shaped clamping working surface is tightly attached to the outer wall of the cable to achieve elastic clamping and fixing of the cable; then connect the end of the cable to the wiring port 17 of the main body of the energy meter 1, and tighten the pressed cable with the screw 18 to complete the connection between the cable and the wiring port 17. After all cables are wired, rotate the mounting bracket 3 to fit the terminal housing of the main body 1 of the energy meter, and lock the bolt 13 through the through hole of the mounting arm to the main body 1 of the energy meter to complete the assembly of the entire anti-tangle assembly. When it is necessary to disassemble the cable, first loosen the bolt 13, rotate the mounting bracket 3 to expose the terminal; then insert the head of a screwdriver or other tool into the blind hole 14 of the clamp arm 11, pry it outward and pull out the guide ring 10, the sliding block 16 slides outward along the sliding groove 15, the clamp arm 11 opens under its own elasticity, releasing the clamp on the cable, then loosen the screw 18 of the terminal port 17, and the cable can be taken out from the cable hole 5 and the cable bundle tube 9. The operation is convenient.

[0028] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
