Fully shielded distributor structure

Abstract

A fully shielded distributor structure includes: a circuit board, an inner enclosure, a first connector, a second connector, and a third connector. The circuit board is electrically connected to a first set of conductive pins, a second set of conductive pins, and a third set of conductive pins. The inner enclosure covers the circuit board and a portion of the first set of conductive pins, the second set of conductive pins, and the third set of conductive pins. The first connector is fitted onto the first set of conductive pins. The second connector is fitted onto the second set of conductive pins. The third connector is fitted onto the third set of conductive pins. A metal shell is assembled onto the inner enclosure and a portion of the first connector, the second connector, and the third connector. The metal shell isolates the internal space from external electric fields or electromagnetic waves to avoid interference from electric fields or electromagnetic waves during signal transmission, thereby achieving full shielding.

Claims

1. A fully shielded distributor structure, comprising: A circuit board having at least a first set of conductive pins, a second set of conductive pins, and a third set of conductive pins electrically connected to different sides of the circuit board; an inner casing covering the circuit board and a portion of the first set of conductive pins, the second set of conductive pins, and the third set of conductive pins; a first connector having a first set of through holes for fitting onto the first set of conductive pins; a second connector having a second set of through holes for fitting onto the second set of conductive pins; and a third connector having a third set of through holes for fitting onto the third set of conductive pins; wherein a metal shell is assembled onto the inner casing and a portion of the first connector, the second connector, and the third connector.

2. A fully shielded distributor structure as described in claim 1, wherein, The metal shell system consists of two shell halves of the same shape that are joined together.

3. A fully shielded distributor structure as described in claim 2, wherein, The two halves of the shell are joined together by screws, snaps, or riveting.

4. A fully shielded distributor structure as described in claim 1, wherein, The metal shell consists of a shell and a cover that are joined together. The shell and the cover can be fastened by screws, snaps, or riveting.

5. A fully shielded distributor structure as described in claim 1, wherein, The first connector, the second connector, and the third connector are each provided with a first annular groove, a second annular groove, and a third annular groove.

6. A fully shielded distributor structure as described in claim 5, wherein, The metal shell has a first protrusion, a second protrusion, and a third protrusion on its bottom and top, respectively. Each of the first, second, and third protrusions forms a first through hole, a second through hole, and a third through hole. When the metal shell is installed on the inner cover, the first, second, and third protrusions are respectively assembled in the first, second, and third annular grooves, so that a portion of the body of the first connector, the second connector, and the third connector is assembled in the first, second, and third through holes.

7. A fully shielded distributor structure as described in claim 6, wherein, The surface of the first protrusion, the second protrusion and the third protrusion of the metal shell is provided with a plurality of extrusion portions. When the first protrusion, the second protrusion and the third protrusion of the metal shell are respectively assembled to the first annular groove, the second annular groove and the third annular groove, the extrusion portions respectively extrude against the inner wall of the first annular groove, the second annular groove and the third annular groove.

8. A fully shielded distributor structure as described in claim 2, wherein, The metal shell is composed of two half shells. Each half shell has a protruding part and a recessed part at the side joint. When the two half shells are assembled, the protruding part and the recessed part of one half shell are respectively assembled with the recessed part and the protruding part of the other half shell.

9. A fully shielded distributor structure as described in claim 1, wherein, Furthermore, there is an outer casing system that covers a portion of the metal housing of the first connector, the second connector, and the third connector, as well as the outer surface of the circuit board, the inner casing, and the metal housing.

10. A fully shielded distributor structure as described in claim 1, wherein, The internal shape of the metal casing is similar to the external outline of the inner covering.
