Technical Field

[0001] The utility model belongs to the technical fields of wind power converters, large-scale grid-side energy storage, industrial and commercial energy storage, household energy storage, frequency converters, UPS, air-conditioning drives, servo drives, etc., and specifically relates to a sensor component that creatively combines the advantages of two Hall sensors and their installation, and uses a low-cost wire-mounted Hall sensor to achieve board-mounted installation. Background Art

[0002] Currently, in industrial applications, Hall sensors are often used for current sampling. According to the different installation methods in the whole machine, Hall sensors are divided into two types: wire-mounted Hall sensors and board-mounted Hall sensors.

[0003] Wire-mounted Hall effect sensors are installed on the power lines outside the PCB and connected to the PCBA via signal lines. This step is performed during the installation of the entire machine. Usually, the Hall effect sensor body is installed and fixed first, and then the signal lines are plugged in. The process is cumbersome and the production cost is high. However, the advantage is that there are many manufacturers of wire-mounted sensors, which makes them easy to select and inexpensive.

[0004] The board-mounted Hall effect sensor and board-mounted power busbar are installed together as plug-in components on the PCB. Both components are used as independent components in PCBA production. The advantages of the board-mounted design include a simple busbar design, no signal wiring, high assembly efficiency, and low production costs. However, the disadvantages are limited availability and high price.

[0005] In view of the characteristics of the above two methods, the utility model proposes a sensor assembly that creatively combines the advantages of two Hall sensors and their installation, uses a low-cost wire-mounted Hall sensor to achieve board-mounted installation, assembles the wire-mounted Hall sensor and the power copper bus into a component, and installs the whole component on the PCB as a plug-in device for PCBA production. The new device is easy to select and has low device cost, and the whole machine is easy to assemble and has low production cost. Utility Model Content
