Patent ID: 8678292

Claim:
A radio frequency identification (RFID) device for connecting a plurality of signal wires, comprising: A metallic plate defining a central axis, a first hole, and a second hole, the metallic plate having a positioning portion surrounding the second hole and formed in the path of the central axis, A first metallic tube having a first conducting core for connecting at least one of the signal wires, a first insulating layer covering the first conducting core, and a first metallic layer covering the first insulating layer, the first metallic layer accessibly disposed on the metallic plate, one end of the first metallic tube being disposed on the positioning portion, the first metallic tube being extended across the first hole and welded to the metallic plate on opposite sides of the first hole, the first insulating later being partially exposed at the corresponding portion of the first metallic tube extending across the first hole; and A second metallic tube having a second conducting core for connecting at least one of the signal wires, a second insulating layer covering the first conducting core, and a second metallic layer covering the second insulating layer, the second metallic layer accessibly disposed on the metallic plate, one end of the second metallic tube being disposed on the positioning portion, the second metallic tube being extended across the second hole and welded to the metallic plate on opposite sides of the second hole, the second insulating later being partially exposed at the corresponding portion of the second metallic tube extending across the second hole; the portion of the second metallic tube extending across the second hole being substantially perpendicular to the portion of the first metallic tube extending across the first hole.
