Description

Technical Field

[0001] This utility model relates to the field of circuit board bracket technology, and in particular to an easily detachable power module bracket for inverter motherboards. Background Technology

[0002] A typical PCBA for an HVAC inverter consists of a filter module, a PFC module, an INV module, an MCU module, and a power supply module. Whether the inverter operates in cooling or heating mode, at the user-set temperature, and the real-time feedback of the process status are all closely related to the MCU module. Since the final decision on whether to select an inverter is made by the customer, the evaluation of whether an inverter has sufficiently powerful functions is closely related to the MCU module. The long-term stable operation of the MCU depends on a reliable power supply module.

[0003] Currently, the power module of the inverter is prone to damage in actual use. The power module and the inverter motherboard are soldered together as a whole. Once damaged, it is very inconvenient to maintain. If the power part cannot be repaired, the entire PCBA needs to be discarded, which can lead to a large cost loss due to a small loss. Utility Model Content

[0004] This utility model mainly provides a convenient maintenance method for the power module of an inverter motherboard. It allows for the replacement of the power module without disassembling and reassembling the entire motherboard. When the power module is unrepairable, the entire power board does not need to be scrapped, thus reducing losses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable power module bracket for a frequency converter motherboard, comprising a frequency converter motherboard, a power module disposed on the top of the frequency converter motherboard, a double row of pin headers mounted on the lower part of the power module, a double row of female headers mounted on the top surface of the frequency converter motherboard, and connection holes opened on the top surface of the double row of female headers. The power module is electrically connected to the frequency converter motherboard by plugging in the connection holes of the double row of pin headers and the double row of female headers. A support plate is snapped onto the outer wall of the power module, a base plate is fixedly connected to the bottom surface of the support plate, a screw is threaded through the top surface of the base plate, and a threaded hole is opened on the top surface of the frequency converter motherboard, with the screw threaded into the inner wall of the threaded hole.

[0006] Preferably, there are two support plates, and a horizontal plate is fixedly connected between the two support plates to improve the strength between the two support plates.

[0007] Preferably, the outer wall of the support plate is fixedly connected with a reinforcing rib plate, and the bottom surface of the reinforcing rib plate is fixedly connected to the top surface of the base plate. The reinforcement rib plate improves the overall strength of the support plate, making it less prone to bending under external force.

[0008] Preferably, the top surface of the base plate has a through mounting hole, and the bottom end of the screw is movably connected to the inner wall of the mounting hole. The mounting hole facilitates the alignment of the mounting hole with the threaded hole, and the base plate is fastened to the top surface of the inverter main board by rotating the screw.

[0009] Preferably, the upper outer wall of the support plate has a slot, and the top surface of the power module is inserted into the inner wall of the slot, so that the support plate can be snapped onto the top surface of the power module through the slot.

[0010] Preferably, the lower outer wall of the support plate is provided with a groove, which supports the bottom surface of the power module and improves the connection stability of the power module.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the power module is electrically connected to the inverter mainboard by inserting and fixing it with a double row of pin headers and a double row of female headers at the bottom of the power module. The double row connection not only achieves a reliable electrical connection, but also facilitates the fixation of the power board. Then, the support plate is snapped onto the top surface of the power module, and the screws are rotated to secure the support plate to the top surface of the inverter mainboard. This allows the power module to be reliably fixed in the X, Y, Z directions and their combinations. This utility model is easy and simple to assemble, and can be fixed with simple plugs and screws. Maintenance is simple, and it is not necessary to disassemble the entire mainboard and perform maintenance and reassembly. Only the power module needs to be replaced. When the power module is not repairable, the entire power board does not need to be scrapped, thereby reducing losses.

[0013] 2. In this utility model, the overall strength of the support plate is improved by setting the reinforcing ribs, making it less prone to bending when subjected to external forces. The slots facilitate the connection of the support plate to the top surface of the power module. The brackets support the bottom surface of the power module, improving the connection stability of the power module. Attached Figure Description
