[0002] A high-voltage frequency converter is a speed regulation control device that changes the output frequency and output voltage to control the speed of an AC high-voltage motor. The frequency converter is a power control device that uses the on-off action of power semiconductor devices to convert the power frequency power supply into electric energy of another frequency. With the rapid development of modern power electronics technology and microelectronics technology, high-voltage high-power frequency conversion speed regulation devices have been continuously matured. The high-voltage problems that have been difficult to solve have been well solved in recent years through device series connection or unit series connection.

[0003] When the existing high-voltage frequency converter is wired, the wiring needs to be inserted into the wiring slot in the wiring board and then fixed by fixing screws. However, for the part of the wiring inserted into the wiring slot, the external insulation skin needs to be stripped off, and the part where the insulation skin is stripped off will be more than the part required to be inserted into the wiring slot, resulting in some of the wired parts with the insulation skin stripped off being exposed outside. If the wired parts with the insulation skin stripped off adhere to dust, it may cause a short circuit or poor contact in the circuit, affecting the use of the wiring. Moreover, there is also a risk of electric leakage in the exposed wiring part.
