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.

Claims

1. 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 second mating-based jack connected to the first mating-based jack and used for receiving the second mating-based plug therein;

two water-proof screw caps wrapping the first and the second mating-based jacks respectively;

a main body having an indentative portion and a fixed main body portion;

an oil ring disposed on the main body; and

a shielding device wrapped in the main body;

wherein an outer portion of the main body is directly wrapped by the water-proof screw caps.

2. The shielded water-proof joint according to claim 1, wherein the shielded water-proof joint is used at an outdoor environment.

3. The shielded water-proof joint according to claim 1, wherein the shielded water-proof joint is fixed on a steel plate of a machine box and the inner conduction wire is a patch code.

4. The shielded water-proof joint according to claim 3, further comprising a slot device receiving the first and second mating-based jack therein.

5. The shielded water-proof joint according to claim 4, wherein the main body receives the slot device therein.

6. The shielded water-proof joint according to claim 5, wherein the slot device has a protrusive portion mating with the indentative portion of the main body.

7. The shielded water-proof joint according to claim 5, further comprising a parking, with the presence of the fixed main body portion of the main body, fixing the shielded water-proof joint on the steel plate.

8. 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 used for transmitting or receiving a signal comprising:

a first mating-based jack receiving the first mating-based plug therein;

a second mating-based jack connected to the first mating-based jack and receiving a second mating-based plug therein;

a main body having an indentative portion and a fixed main body portion;

an oil ring disposed on the main body;

two water-proof screw caps wrapping the first and the second mating-based jacks; and

a shielding device wrapping the second mating-based plug.

9. The shielded water-proof joint according to claim 8, wherein the shielded water-proof joint is used at an outdoor environment.

10. The shielded water-proof joint according to claim 8, wherein the shielded water-proof joint is fixed on a steel plate of a machine box and the inner conduction wire is a patch code.

11. The shielded water-proof joint according to claim 8, further comprising a slot device receiving the first and second mating-based jacks therein.

12. A water-proof joint connecting a first mating-based plug to an inner conduction wire comprising:

a first mating-based jack receiving the first mating-based plug therein;

a second mating-based jack connected to the first mating-based jack and receiving a second mating-based plug therein;

a main body having an indentative portion and a fixed main body portion;

an oil ring disposed on the main body; and

two water-proof screw caps wrapping the first and the second mating-based jacks.

13. The water-proof joint according to claim 12, further comprising a shielding device wrapping the second mating-based plug and wherein the inner conduction wire has the second mating-based plug and a third mating-based plug and transmits or receives a signal.

14. The water-proof joint according to claim 12, wherein the shielded water-proof joint is used at an outdoor environment.

15. The water-proof joint according to claim 12, wherein the shielded water-proof joint is fixed on a steel plate of a machine box and the inner conduction wire is a patch code.
