3, according to the number of cores and the appearance of the 1 core-12 core, mini plug, standard plug, big D plug, waterproof electronic wire, SM air butt, extension cord live connector, T-type tee waterproof plug, Y last name waterproof plugs, a towing waterproof plugs
< strong>three, waterproof plug installation
Outdoor waterproof plug selection and installation than the indoor more need to pay attention to the following issues: waterproof plug as far as possible to be installed in a hidden place, the house against the wall so that it is not easy to rain in the rainy days to the rain; in the rainy days it is best to the outdoor power outage to avoid the phenomenon of leakage.
