Technical Field

[0001] This utility model relates to the field of frequency converter technology, and in particular to a temperature detection device for frequency converters. Background Technology

[0002] After the inverter is manufactured and assembled, the internal temperature of the product will be tested according to the requirements of the usage environment to verify whether the internal temperature of the product meets the design requirements.

[0003] A frequency converter temperature detection device is disclosed in Chinese patent CN210166049U. After studying the existing technology and the above-mentioned patent, it was found that the internal temperature of the frequency converter is mostly detected by temperature detection wires. However, the temperature detection wires are expensive and inconvenient to install. This utility model proposes a frequency converter temperature detection device. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a temperature detection device for frequency converters.

[0006] The purpose of this utility model is achieved through the following technical solution: a temperature detection device for a frequency converter, comprising a base plate, a circuit board fixedly connected to the top of the base plate, a heat dissipation fin fixedly connected to the top of the circuit board, a mounting plate fixedly connected to the side of the base plate near the heat dissipation fin, a vertical rod fixedly connected to the top of the mounting plate, connecting screws threadedly connected to both sides of the mounting plate, a threaded hole opened inside the vertical rod, a screw threadedly connected inside the threaded hole, a rotating plate fixedly connected to one end of the screw, a housing rotatably connected to the other end of the screw, a temperature detection aluminum plate snapped into the inside of the housing, a connecting wire fixedly connected to the top of the temperature detection aluminum plate, a wire groove opened at the top of the vertical rod, the connecting wire snapped into the inside of the wire groove, and a temperature display electrically connected to the end of the connecting wire.

[0007] Preferably, a connecting hole is provided at the center of one side of the housing, and a rotating groove is provided inside the connecting hole. The rotating plate is rotatably connected to the inside of the rotating groove. The diameter of the connecting hole is adapted to the diameter of the screw, and the diameter of the rotating plate is adapted to the inner diameter of the rotating groove.

[0008] By adopting the above technical solution, the rotating plate can rotate inside the rotating groove when the screw is rotated. Therefore, the housing and the temperature detection aluminum plate on the other side do not need to rotate, thus avoiding friction between the temperature detection aluminum plate and the heat dissipation fins.

[0009] Preferably, a knob is fixedly connected to the end of the screw. The knob is a circular plate, and the diameter of the knob is larger than the diameter of the screw.

[0010] By adopting the above technical solution, the distance between the end of the screw and the heat dissipation fins can be adjusted by turning the knob.

[0011] Preferably, the vertical rod is a rectangular rod, which is welded to the center of the top of the mounting plate, and the threaded hole is located at the center of the vertical rod.

[0012] By adopting the above technical solution, the mounting plate and connecting screws can stably install the vertical rod.

[0013] Preferably, the groove is located at the center of the top of the vertical rod, the groove is an arc-shaped groove, and the diameter of the connecting wire is adapted to the inner diameter of the groove.

[0014] By adopting the above technical solution, the connecting wires can be snapped into the wire groove, achieving the purpose of quick wire management.

[0015] Preferably, the housing is a square plate, and a slot is provided on one side of the housing. One side of the temperature sensing aluminum plate is snapped into the inside of the slot, and one end of the connecting wire is welded to the center of the top of the temperature sensing aluminum plate.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The temperature detection device of this frequency converter has a vertical rod and a mounting plate fixedly connected to the side of the base plate near the heat dissipation fins. The top of the mounting plate is fixedly connected to the vertical rod, and the left and right sides of the mounting plate are threaded with connecting screws. In use, the mounting plate can be fixed to the side of the base plate near the heat dissipation fins by connecting screws. Rotating the knob in the forward direction will make the temperature detection aluminum plate at the end of the screw overlap with the surface of the heat dissipation fins, which can quickly complete the installation of the temperature detection aluminum plate. The overlapping method facilitates the installation and removal of the temperature detection aluminum plate and the installation speed is relatively fast. The connecting wires can be clipped into the inside of the wire groove, which can prevent the connecting wires from contacting the high temperature heat dissipation fins and achieve the purpose of protecting the connecting wires.
