The safety clearance settings for high-voltage connectors in microwave ovens must strictly follow equipment design standards. Typically, a minimum distance of 3–5 mm is required between adjacent conductive components to prevent high-voltage breakdown or arc discharge. In practice, key contact distances can be measured using a vernier caliper and verified against the electrical specifications in the product manual. If structural constraints necessitate adjustments to the spacing, physical separation using insulating sleeves or ceramic spacers must be implemented, ensuring that all fastening components are secure and free from loosening risks.

In terms of waterproofing, standard household microwave connectors generally do not require special protection. However, in humid or dusty environments, it is recommended to seal the interfaces using silicone gaskets or potting processes. For high-voltage terminals, priority should be given to high-temperature-resistant materials such as polyurethane coatings or fluororubber, which not only block moisture penetration but also withstand the high-temperature environment inside the microwave. It is important to ensure that waterproof measures do not compromise the connector’s heat dissipation performance, avoiding excessive sealing that could lead to heat accumulation. Additionally, regular inspections for aging of sealing components and timely replacement of cracked or deformed protective layers can effectively reduce the risk of short circuits.
