1. Aging resistance: Have good stability like heat, heat radiation, air, ozone and ect.
2. Corrosion resistance: Have strong resistance about dilute acid, salt water, oxidants, and aliphatic hydrocarbons.
3. Sealing technology: Use repeatable open seal components to ensure good airtight waterproof performance.
4. Mechanical properties: To withstand harsh conditions such as vibration, impact, cable distortion and strong tensile changes such as temperature.
5. Locking device: Do not require special tools and easy to install and open repeatedly.
6. Disagreements: 2 into 2 out, 3 into 3 out, 4 into 4 out and other designs.
7. Continued functions: Use laminated clamshell structure,and do not need to disassemble the other connecting plate when operating.
