  • Ventilation waterproof connector
    Patent number: 4828507
    Abstract: To easily change an ordinary waterproof connector to a ventilation waterproof connector provided with a ventilation tube for introducing an atmospheric pressure into the connector housing to reduce pressure difference between inside and outside of the connector, a single ventilation tube is mechanically fixed to a connector terminal in the same way as when plural connector wires are electrically fixed to the same connector terminals, without changing the housing structure or preparing additional parts.
