Connector cracked after outdoor use.
prob_01
Common root cause: Prolonged exposure to UV rays and temperature fluctuations degrades the connector body plastic (PPO/PC).
Step-by-step solution: 1. Check if the connector is exposed to direct sunlight for extended periods without protection. 2. Consider replacing the connector with a model offering higher UV resistance or use a protective coating.
💡 Pro tip: Store connectors in indirect sunlight or a protected area when not in prolonged use.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if, after following all instructions for correct installation and use, the connector exhibits evident manufacturing defects, such as premature cracking of the plastic body, sealing failure causing water ingress even without mechanical stress, or metal terminals that detach easily, indicating a defect that compromises the product's functionality and safety. Refer to the seller's warranty and marketplace return policy.
