[0001] This utility model belongs to the field of power metering technology, specifically relating to a power metering device that can be installed on a PCB board and the PCB board itself. Background Technology
[0002] A power metering module, also known as an energy metering module, is a device used to measure and record electrical energy consumption. Its main principle is to calculate energy consumption by measuring current and voltage. A power metering module typically includes a current transformer (CT) and a voltage transformer (VT), which convert current and voltage into measurable signals.
[0003] In existing technologies, power metering modules mounted on PCB boards generate heat during use. If this heat cannot be dissipated, prolonged high-temperature accumulation can damage the power metering module, significantly reducing its lifespan. To address this issue, we propose a power metering module that can be mounted on a PCB board. Utility Model Content

[0009] Preferably, the base is U-shaped, including a base and two oppositely arranged side walls, the two side walls are located on both sides of the base, and each side wall is provided with multiple hollow slots; multiple sets of heat dissipation fins on the side plate pass through the multiple hollow slots and extend beyond the side wall.
[0010] Preferably, a first stop bar is provided at one of the openings of the seat, and the two ends of the first stop bar are respectively connected to the two side walls.
[0011] In a preferred embodiment of the present invention, a detachable second stop bar is provided at one or both openings of the seat body. The second stop bar is arranged across the opening of the seat body and is detachable from the two side walls.
[0012] Preferably, both sidewalls are provided with through grooves at one or both openings of the seat, and the two ends of the second stop rod are respectively inserted into the through grooves of the two sidewalls, and one end of the second stop rod is fixed to each other by a locking structure.

[0033] Example 1
[0034] See Figures 1-4This embodiment discloses a power metering device that can be mounted on a PCB board, including a base 1, a heat conduction frame 4, and a power metering module 2. The power metering module 2 includes a body 201 and a lead wire 202, with the lead wire 202 located on one side of the body 201. Specific implementation details of the power metering module 2 in this embodiment can be found in the prior art. The heat conduction frame 4 is mounted on the base 1, and the power metering module 2 is mounted on the heat conduction frame 4. The base 1 can be mounted on a PCB board. The heat conduction frame 4 has multiple sets of heat sinks located on the outer side of the power metering module 2. In this embodiment, the heat sinks can be made of copper; specific implementation details can also refer to heat dissipation fins or other fins with good heat dissipation effects in the prior art.
[0035] Furthermore, in this embodiment, the heat-conducting frame 4 is U-shaped, including a base plate 401 and two side plates 402, both of which can be made of copper. The two side plates 402 are opposite each other and located on both sides of the base plate 401. Multiple sets of heat sinks are evenly spaced on the outer walls of the two side plates 402. Each set of heat sinks can contain multiple heat sinks and can be bonded to the side plates 402 with thermally conductive adhesive. The U-shaped heat-conducting frame 4 has a simple structure and facilitates the fixing of the power metering module 2. The body 201 of the power metering module 2 can be bonded to the base plate 401 of the heat-conducting frame 4 with thermally conductive adhesive. During operation, the heat generated by the power metering module 2 can be conducted to the side plates 402 and the heat sinks located on the side plates 402 through the heat-conducting frame 4, and then the heat is quickly released by the heat sinks. Since multiple sets of heat sinks are provided, the contact area with air can be increased, thereby improving the heat dissipation speed.
[0036] Furthermore, in this embodiment, the number of heat sinks on the side plate 402 is the same, which allows the heat generated by the power metering module 2 to be evenly dissipated from both sides, avoiding heat accumulation and accelerating heat dissipation, thus reducing the impact on the PCB board as quickly as possible.
[0037] In this embodiment, the base 1 is also U-shaped, including a base 101 and two oppositely arranged side walls 102. The base 101 is fixed to the PCB board, and the two can be bonded together with thermally conductive adhesive. The two side walls 102 are located on both sides of the base 101, and each side wall 102 is provided with multiple hollow slots; multiple sets of heat sinks on the side plate 402 pass through the multiple hollow slots and extend beyond the side wall 102. In this embodiment, both the base 1 and the heat conduction frame 4 are U-shaped, which makes them more compatible and facilitates the installation and fixation of the power metering module 2.
[0038] Furthermore, in this embodiment, a first stop bar 105 is provided at one of the openings of the seat 1, and the two ends of the first stop bar 105 are respectively connected to the two side walls 102. Multiple first stop bars 105 can be provided in this embodiment, and their number can be flexibly adjusted. Specifically, in this embodiment, two first stop bars 105 are provided. The first stop bars 105 serve two purposes: firstly, they can position the power metering module 2, and secondly, they can prevent the power metering module 2 from detaching from the heat-conducting frame 4. The two ends of the first stop bars 105 in this embodiment can be fixed to the side walls 102 by welding, bonding, or other methods.
[0039] In this embodiment, a detachable second stop bar 5 is provided at another opening of the seat body 1. The second stop bar 5 is horizontally arranged across the opening of the seat body 1 and is detachable from the two side walls 102. Each of the two side walls 102 is provided with a through groove 103 at one of the openings of the seat body 1. The two ends of the second stop bar 5 are respectively inserted into the through grooves 103 of the two side walls 102, and one end of the second stop bar 5 is fixed to each other by a locking structure.
[0040] The locking structure of this embodiment includes a locking member 7; a fixing block 6 is provided at one end of the second stop 5, the fixing block 6 being larger than the through groove 103; the locking member 7 is disposed on the fixing block 6; one side wall 102 is provided with a threaded hole 104 corresponding to the locking member 7, and the locking member 7 is threadedly engaged with the threaded hole 104. After the power metering module 2 is installed and fixed in the inner cavity of the heat conduction frame 4, the second stop 5 is inserted into the through groove 103 of the two side walls 102, and then the locking member 7 on the fixing block 6 is engaged with the threaded hole 104 on the side wall 102 to lock and fix the second stop 5. The locking member 7 in this embodiment can be a screw, bolt, etc. By providing a detachable second stop 5, the disassembly and assembly of the power metering module 2 is facilitated, making it convenient for subsequent maintenance or replacement of the power metering module 2.
[0041] Example 2
[0042] The difference between this embodiment and Embodiment 1 is that: in this embodiment, the openings on both sides of the base 1 are provided with detachable second stop bars 5, and through slots 103 are provided at both ends of the two side walls 102. This allows the power metering module 2 to be inserted from the openings on both sides, followed by the assembly of the second stop bars 5.
[0043] Example 3
[0044] This embodiment discloses a PCB board that includes a power metering device that can be mounted on a PCB board, as described in Embodiment 1 or Embodiment 2. The PCB board includes a substrate and a power metering device that can be mounted on the PCB board, with the base 101 of the power metering device fixed on the substrate.
[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
