[0014] (III) Beneficial Effects

[0015] This utility model provides a refrigerator frequency converter, which has the following beneficial effects:

[0016] 1. This refrigerator inverter controller, through its wiring mechanism, allows for convenient wiring by pushing the rotating plates on both sides of the connector, causing the locking blocks at the ends of the rotating plates to move closer to the connector. The connector is then inserted into the wiring port. Releasing the rotating plates, under the counterforce of the supporting spring at the back, returns the locking blocks at the ends of the rotating plates to their initial position, engaging with the two positioning blocks on the inner wall of the wiring port. Similarly, pushing the rotating plates separates the locking blocks from the positioning blocks, allowing the connector to be pulled out of the wiring port. This facilitates wiring for workers and is more efficient than traditional bolt-based positioning, improving installation and maintenance efficiency.

[0017] 2. The refrigerator inverter controller features a protective mechanism. When wiring, the protective cover is opened and limited by hooks. After wiring is completed, the hooks are released, and the protective cover automatically adheres to the surface of the inverter controller body under the push of torsion springs on both sides of the top, effectively blocking the wire heads and terminals. This effectively reduces external dust from falling onto the wire heads and entering the terminals, preventing contamination of internal electronic components and affecting their normal operation.

[0025] The protective cover 704 is made of acrylic. The fixing post 701 is rotatably connected to the inside of the rotating post 703. The protective cover 704 serves to prevent dust.

[0026] Two handles 8 are fixedly connected to the surface of the protective cover 704. The surface of the handles 8 is provided with positioning holes. The handles 8 are designed to pull the protective cover 704.

[0027] Ropes 9 are fixedly connected to both sides of the surface of the main body 1 of the frequency converter. Hooks 10 are fixedly connected to the ends of the ropes 9. The hooks 10 are inserted into the positioning holes. The hooks 10 serve to limit the movement of the protective cover 704.

[0031] In this invention, the working steps of the device are as follows:
