[0040] In this embodiment, by setting the mounting frame 110 and the mounting plate 120 together as the main structure of the source meter device, the first printed circuit board 200 can be installed on the fixed structure 130 in the first mounting space to become a single-channel source meter device. Furthermore, by adding a second printed circuit board 300 on the fixed structure 130 in the second mounting space, it can become a dual-channel source meter device. This not only supports both single and dual channels, but also has a simple structure, which helps to firmly fix the first printed circuit board 200 and the second printed circuit board 300, resulting in high reliability.

[0041] One embodiment provides a source meter device, please refer to... Figures 1-5 The source meter device includes a mounting bracket 100 and a first printed circuit board 200.

[0042] Please refer to Figure 1The mounting bracket 100 can be understood as the mounting base for electronic components in the source meter device, providing a mounting surface for electronic components such as circuit boards and power modules 500. The mounting bracket 100 is configured to be compatible with both single-channel and dual-channel source meter devices. A single-channel source meter device can be formed by mounting the first printed circuit board 200 on the mounting bracket 100.

[0043] In one embodiment, please refer to Figure 1 The source meter device also includes a second printed circuit board 300. By adding a second printed circuit board 300 to the mounting bracket 100 on the basis of the single-channel source meter device, a dual-channel source meter device can be formed.

[0044] In some embodiments, please refer to Figure 2 The first printed circuit board 200 has a main control board 210 and a first test circuit 220 electrically connected to each other to form a first test channel. The second printed circuit board 300 has a second test circuit 310 identical to the first test circuit 220. The second test circuit 310 can be electrically connected to the main control board 210 to cooperate in forming a second test channel. By placing the main control board 210 on the first printed circuit board 200, the first printed circuit board 200 can form an independent first test channel to constitute a single-channel source meter device. By adding the second printed circuit board 300 on the mounting bracket 100 and electrically connecting the second test circuit 310 to the main control board 210, the main control board 210 and the second test circuit 310 can cooperate to form a second test channel, thereby constituting a dual-channel source meter device.

[0045] Those skilled in the art will understand that the above-described electrical connections can all be cable connections or other connection methods capable of achieving electrical connection. In other embodiments, the main control board 210 can also be located in other positions within the source meter device, and can be electrically connected to the first test circuit 220 and the second test circuit 310 as needed to form a first test channel and a second test channel.

[0046] In some embodiments, the components in the first test circuit 220 and the second test circuit 310 can be configured to be common to both, in order to reduce the types of components and facilitate assembly and management.

[0047] Furthermore, the functionally identical parts in the first test circuit 220 and the second test circuit 310 can be packaged into at least one integrated functional module that is common to both, making the integrated functional module a common component of the first test circuit 220 and the second test circuit 310, so as to quickly assemble the first test circuit 220 and the second test circuit 310, which helps to improve the production efficiency of the first printed circuit board 200 and the second printed circuit board 300.

[0048] In some embodiments, please refer to Figure 2 A first heat sink 230 may be provided on the first printed circuit board 200. The first heat sink 230 is electrically connected to the first test circuit 220. The main control board 210 is disposed on one side of the first heat sink 230 so that the first heat sink 230 can dissipate heat for the first printed circuit board 200. A second heat sink 320 may be provided on the second printed circuit board 300. The second heat sink 320 is electrically connected to the second test circuit 310 so that the second heat sink 320 can dissipate heat for the second printed circuit board 300.

[0049] For example, please refer to Figure 1 and Figure 2 The first radiator 230 and the second radiator 320 are arranged opposite to each other, with one end of the first radiator 230 and one end of the second radiator 320 aligned. A cooling fan 400 can be provided at the aligned end of the first radiator 230 and the second radiator 320. Air ducts are provided in both the first radiator 230 and the second radiator 320 corresponding to the cooling fan 400. The cooling fan 400 can be sealed to both the first radiator 230 and the second radiator 320 so as to dissipate heat by utilizing the airflow generated by the operation of the cooling fan 400.

[0050] In a further embodiment, the length of the first heat sink 230 may be less than the length of the second heat sink 320, and the main control board 210 may be disposed at the end of the first heat sink 230 away from the cooling fan 400. By arranging the first heat sink 230 and the main control board 210 in the same position as the second heat sink 320, the remaining areas on the first printed circuit board 200 and the second printed circuit board 300 can be used to install the first test circuit 220 and the second test circuit 310, which helps to make corresponding components in the first test circuit 220 and the second test circuit 310 adopt the same arrangement position, facilitating assembly.

[0051] In some embodiments, in order to improve the heat dissipation effect, thermal pads (not shown in the figure) can be provided for both the first heat sink 230 and the second heat sink 320. The thermal pads can be provided between the first heat sink 230 and the board body of the first printed circuit board 200, and between the second heat sink 320 and the board body of the second printed circuit board 300, or between the first heat sink 230 and the second heat sink 320 and the corresponding heat-generating components.

[0052] In one embodiment, please refer to Figure 3The mounting bracket 100 includes a mounting frame 110 and a mounting plate 120. The mounting frame 110 has two oppositely arranged side walls 111. The mounting plate 120 is connected between the two opposite side walls 111 of the mounting frame 110, so that a first mounting space and a second mounting space are formed on both sides of the mounting plate 120 within the mounting frame 110. A fixing structure 130 is provided in both the first mounting space and the second mounting space. The fixing structure 130 in the first mounting space is used to install and fix the first printed circuit board 200 to form a first test channel. The fixing structure 130 in the second mounting space is used to install and fix the second printed circuit board 300 to form a second test channel.

[0053] In one embodiment, please refer to Figure 3 The mounting frame 110 has a connecting portion 112 that connects to the same end of the two side walls 111. The connecting portion 112 and the two side walls 111 are integrally connected, so that the mounting frame 110 is U-shaped, which helps to improve the overall integrity of the mounting frame 110 and enhance the structural reliability. For example, the mounting frame 110 can be integrally bent into a U-shape by a sheet metal, with the middle of the sheet metal serving as the connecting portion 112, and the two sides of the sheet metal forming two opposing side walls 111 of the mounting frame 110.

[0054] The mounting plate 120 can be a sheet metal part and can be riveted and fixed to the middle of the two side walls 111 along its own width direction, so that the first mounting space and the second mounting space are respectively formed in Figure 1 The upper and lower sides of the mounting plate 120 are shown in the view shown, and the structures of the first mounting space and the second mounting space are approximately the same, so as to install the first printed circuit board 200 and the second printed circuit board 300.

[0055] Those skilled in the art will understand that the mounting frame 110 may also omit the connecting part 112, with the two side walls 111 connected only by the mounting plate 120, or it may be configured with other shapes and structures to meet the installation requirements of the relevant components. The connection method of the mounting plate 120 to the two side walls 111 is not limited; it may also be connected to the side walls 111 by welding, bonding, or snap-fitting.

[0056] In one embodiment, please refer to Figure 3 The fixing structure 130 includes a plurality of fasteners 131 arranged in rows on the two side walls 111 for mounting the first printed circuit board 200 or the second printed circuit board 300. The fixing structure 130 helps to form a multi-point fixing method and improves the fixing reliability.

[0057] In one embodiment, please refer to Figure 3The fastener 131 can be riveted to the side wall 111 for secure installation. The fastener 131 can have a threaded through hole for installing fasteners for fixing the first printed circuit board 200 or the second printed circuit board 300.

[0058] For example, multiple fasteners 131 are riveted to each of the two side walls 111, and the fasteners 131 on the two side walls 111 can be arranged in pairs to fix the first printed circuit board 200 and the second printed circuit board 300 from both sides. The fasteners 131 are provided with threaded through holes along the thickness direction of the mounting plate 120. The first printed circuit board 200 and the second printed circuit board 300 can be mounted on the side of the fasteners 131 away from the mounting plate 120. The edges of the first printed circuit board 200 and the second printed circuit board 300 can be provided with mounting holes for fasteners to pass through, so as to be fixed to the fasteners 131 by fasteners such as screws or bolts, which helps to improve the fixation reliability.

[0059] In one embodiment, please refer to Figure 3 The mounting plate 120 has a first positioning protrusion 121 facing the first mounting space, and the first printed circuit board 200 has a first positioning hole 240. The first positioning protrusion 121 is inserted into the first positioning hole 240 to position the first printed circuit board 200. The mounting plate 120 has a second positioning protrusion 122 facing the second mounting space, and the second printed circuit board 300 has a second positioning hole 330. The second positioning protrusion 122 is inserted into the second positioning hole 330 to position the second printed circuit board 300. The arrangement of the first positioning protrusion 121, the second positioning protrusion 122, the first positioning hole 240, and the second positioning hole 330 facilitates the positioning of the first printed circuit board 200 and the second printed circuit board 300, which not only facilitates installation but also improves assembly reliability.

[0060] In one embodiment, please refer to Figure 4 The first positioning protrusion 121 and the second positioning protrusion 122 are both provided with connecting holes. The connecting holes can be set through the mounting plate 120. The connecting holes are connected to connectors 123. Connectors 123 are used to connect the corresponding first printed circuit board 200 or second printed circuit board 300 to connect the first printed circuit board 200, the mounting plate 120 and the second printed circuit board 300 into a whole, which helps to improve the stability of the connection structure.

[0061] For example, the mounting plate 120 has two first positioning protrusions 121 spaced apart towards the first mounting space, and two second positioning protrusions 122 spaced apart towards the second mounting space. The first positioning protrusions 121 and the second positioning protrusions 122 are arranged alternately along the length of the mounting plate 120. The first printed circuit board 200 may have two first positioning holes 240 arranged side by side, penetrating its body and the first heat sink 230. The second printed circuit board 300 may have two second positioning holes 330 arranged side by side, penetrating its body and the second heat sink 320. The first positioning protrusions 121 are inserted into the first positioning holes 240, and the second positioning protrusions 122 are inserted into the second positioning holes 330.

[0062] Both the first positioning protrusion 121 and the second positioning protrusion 122 are provided with connecting holes that penetrate the mounting plate 120. The connecting holes can be threaded holes. Bolts can be installed in both the first positioning hole 240 and the second positioning hole 330 as connecting parts 123. The bolts are connected to the first positioning protrusion 121 and the second positioning protrusion 122 through the connecting holes, thereby connecting the first printed circuit board 200, the mounting plate 120 and the second printed circuit board 300 into a whole.

[0063] In other embodiments, only the first positioning protrusion 121 and the first positioning hole 240 may be provided, or only the second positioning protrusion 122 and the second positioning hole 330 may be provided, as long as the design and usage requirements are met.

[0064] Because the components on the first printed circuit board 200 and the second printed circuit board 300 have different heights, in order to save installation space and reduce the material cost of the source meter device, in one embodiment, please refer to... Figures 1-3 The first printed circuit board 200 and the second printed circuit board 300 can be arranged opposite each other, so that the components on both the first and second printed circuit boards 300 face the mounting plate 120. This allows taller components on the first printed circuit board 200 to be installed using the second mounting space, and taller components on the second printed circuit board 300 to be installed using the first mounting space. To prevent interference between the components installed on the first and second printed circuit boards 200 and 300 due to their identical positions, one of the first and second printed circuit boards 200 can be rotated by a certain angle, for example, rotating the second printed circuit board 300 by 180°, so that the components requiring installation on the first and second printed circuit boards 200 and 300 are misaligned.

[0065] To allow components mounted on the first printed circuit board 200 and the second printed circuit board 300 to enter their corresponding first or second mounting spaces, the mounting plate 120 may be provided with a clearance structure 124 for avoiding at least some of the components on the first printed circuit board 200 and the second printed circuit board 300. Those skilled in the art will understand that the clearance structure 124 may be a hole, slot, or recess, etc.

[0066] In one embodiment, please refer to Figure 1 A power module 500 is fixed on one side wall 111 of the mounting plate 120. A clearance notch 125 is provided on the mounting plate 120 corresponding to the installation position of the power module 500. The power module 500 can be provided with two circuit connectors, for example, one circuit connector is provided at each end of the power module 500, so as to connect to the first printed circuit board 200 and the second printed circuit board 300 respectively through cables, thereby supplying power to the first printed circuit board 200 and the second printed circuit board 300.

[0067] In one embodiment, please refer to Figure 1 , Figure 4 and Figure 5 The source meter device may include a housing 600, the housing 600 having a mounting cavity 610, and a mounting frame 110 disposed in the mounting cavity 610.

[0068] For example, the housing 600 can be a cylindrical structure formed by bending and connecting sheet metal parts, so that a mounting cavity 610 is formed inside the housing 600. The size of the mounting cavity 610 can be adapted to the size of the mounting frame 110 so that the mounting frame 110 can be fixed in the mounting cavity 610. A first panel 700 and a second panel 800 can be respectively provided at the two ends of the housing 600 to close the openings at both ends of the housing 600. The first panel 700, the second panel 800 and the housing 600 together form the external outline of the source device, protecting the mounting bracket 100, the first printed circuit board 200 and the second printed circuit board 300, etc.

[0069] In some embodiments, heat dissipation holes may be provided on the housing 600 to dissipate heat from the source meter device.

[0070] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
