Abstract: Disclosed is a shielded water-proof joint connecting a first mating-based plug to an inner conduction wire having a second mating-based plug and a third mating based plug and transmitting/receiving a signal, comprising a first mating-based jack for receiving the first mating-based plug therein, a water-proof device wrapping the first mating-based jack, a second mating-based jack connected to the first mating-based jack and used for receiving the second mating-based plug therein, a printed circuit board (PCB) connected electrically to the first and second mating-based plugs, and a shielding device wrapping the PCB and second mating-based plug.

Abstract: A dust-proof cover for a network jack is provided. The dust-proof cover includes a cover body having a covering surface, a connecting portion disposed on the cover body, and a fixing portion mounted outwardly on the connecting portion and connected to the cover body through the connecting portion to fix the cover body to the network jack so that the covering surface closely seals the opening of the network jack.
