[0025] Compared to the inverter connector disclosed in Chinese Patent No. CN202420768894.8, which requires vertical space due to the upper and lower compartment design and the upper and lower conductive plate design, the present invention designs the first to fourth conductive plates in a left-right interlocking design, making the four conductive plates more compact and further reducing the overall size of the connector and installation space.

[0026] In addition, this utility model changes the wiring method on the load side to a concealed design (i.e., the second wiring screw), which brings the following advantages:

[0027] 1) Space saving and optimized layout: By concealing functional components, the product can be more compact, reducing external protrusions and facilitating installation or use in limited spaces.

[0028] 2) Enhanced protection: Internal components are less susceptible to external environmental factors (such as dust, moisture, or physical impacts), thus extending product lifespan.

[0029] 3) Enhanced security and ease of use: The built-in design reduces the risk of accidental touches by users, while the intelligent layout makes operation more intuitive.

[0030] 4) Environmental adaptability: This design can better adapt to different usage scenarios and avoid interference or damage by reducing exposed elements.

[0031] 5) Durability and sustainability: Protects internal components from external factors, reducing wear and tear and failure rate.

[0032] 6) Enhanced aesthetics: The concealed design eliminates unnecessary visual distractions, making the product look smoother and more upscale, and enhancing the overall comfort and satisfaction of the product.

[0033] The waterproof sealing design at the bottom of the insulating base and the embedded molding of the conductive plate with the main body (insulating base) of this utility model meet the IP66 waterproof rating.

[0034] This utility model achieves dustproof and electric shock protection through the design of a protective cover.

[0035] The insulating spacer, insulating plug, and protective cover described in this utility model achieve insulation and protection against electric shock. Attached Figure Description
