[0004] In the prior art of the above-mentioned patent, a rubber sleeve is used to fix the connecting wire to the terminal. However, since there is a gap between the rubber sleeve and the terminal, water vapor will penetrate through the gap. The water vapor will cause the insulation performance of the terminal to deteriorate, resulting in short circuit, leakage, breakdown, low insulation resistance and other problems. In addition, the rubber sleeve fixing method will cause the connecting wire to be unstable in installation and easily detached from the terminal, affecting the use of the compressor.

[0016] (1) The connecting plate is provided with a conductive plate and a triangular rod. After the connecting plate and the rotating plate are fitted together, the two conductive plates and the triangular rod clamp the connecting wire to prevent the connecting wire from being separated from the terminal. The extrusion groove and the wire release groove press against the outer sheath of the connecting wire through the sharp cone and the anti-stripping sharp cone to scrape the connecting wire, so that the connecting wire is completely fixed between the connecting plate and the rotating plate. The waterproof rubber pad and the sealing strip increase the friction between the connecting wire and the waterproof rubber pad and the sealing strip by squeezing the connecting wire and the groove and the concave ring groove on the waterproof rubber pad, further increasing the fixing strength of the connecting wire to prevent the connecting wire from being separated from the terminal.
