Waterproof connectors can be used in industrial, military, or other production fields, so obtaining CQC certification is very important. CQC certification refers to the China Quality Certification Center. This certification involves product environmental protection, product performance, product safety, and product organic properties. Only after passing the certification will the relevant certification mark be issued.

It is recommended to check whether the waterproof connector has passed CQC certification when purchasing. If the waterproof connector manufacturer's product does not pass the relevant certification of the China Quality Certification Center, it can indicate that there are certain safety hazards in the use of the product.
