1. Size structure: The waterproof level of waterproof connectors is generally IP68/IP67/IP66/IP65 (analyze the volume in the conceptual design. The waterproof usb manufacturer tells you that the smaller the size, the more difficult it is to meet the requirements for waterproofing and connection. The waterproof level is also lower. In terms of structure, observe whether the position of the wearing parts and the waterproof position are reasonable. For example, the silicone gasket should not be too exposed to prevent ultraviolet corrosion from affecting the performance and life.

2. Shell material: The shell material should choose materials with strong toughness, temperature resistance, flame retardant and anti-corrosion, such as PA66 wire with soft, flame-retardant, wear-resistant and corrosion-resistant materials, such as PVC and rubber.

3. Production technology: The product feels comfortable and textured, not too smooth or rough, there should be no burrs in the work, and it should feel naturally not smooth when connecting the joints. Users can evaluate the manufacturer's production technology and strength through field surveys and samples.

4. Pins: Good waterproof connector pins are generally solid pure copper. The pins are gold-plated or nickel-plated to increase the conduction performance. Users should pay attention when purchasing to prevent bad manufacturers from filling them with hollow copper pins.

5. Copper wire: The material of copper wire is generally pure copper copper wire. Now powerful manufacturers handle the wire by themselves to ensure the quality while controlling the cost.

So today's explanation is here first. The above is the whole content of today. I believe that everyone has a certain understanding of judging the quality of waterproof connectors.
