Abstract

A guide rail (

1) for receiving a GBIC module therein mounts to a printed circuit board (

2) and includes a frame (

10) having a receiving space (

26) for receiving the GBIC module therein, a metallic cover (

12), and a connector assembly (

14) and two pairs of supporting poles (

15) fastened to the frame for elevating the frame a given distance above the printed circuit board. The frame includes four side lugs (

28) at outer walls thereof for attachment to selected ends of the respective supporting poles by four bolts (

78). The lower ends of the supporting poles are mounted onto the printed circuit board. The connector assembly has a second connector (

104) downwardly extending beyond a bottom surface (

124) of the frame and mounted onto the printed circuit board, helping elevate the frame a given distance above the printed circuit board.

Claims

1. A guide rail system for receiving a GBIC module therein, comprising:

2. The guide rail system as recited in claim 1, wherein the frame includes at lease two side lugs at opposite sides thereof supported by at least a pair of poles arranged between said side lugs and said printed circuit board.

3. The guide rail system as recited in claim 1, wherein said connector assembly includes a first connector securely received in a rear portion of said frame, a second connector electrically connected to said printed circuit board and a printed substrate electrically joining the first and the second connectors.

4. The guide rail system as recited in claim 3, wherein said second connector is enclosed by a metal shell.

5. The guide rail system as recited in claim 3, wherein said second connector includes a plurality of header pins supported by a base, an extension having a plurality of passageways and being attached to the base, and a metal shell securely attaching the base to the extension.

6. The guide rail system as recited in claim 5, wherein said passageways of said extension each are slightly larger than a cross section of the header pins so that, when assembled, a narrow air space exists between each header pin and interior walls of each corresponding said passageway.

7. The guide rail system as recited in claim 6, wherein said passageways each include an outlet dimensioned such that the header pin is snugly fitted therein.

8. The guide rail system as recited in claim 5, wherein said metal shell includes a pair of board locks electrically connected to the substrate.

9. A guide rail assembly adapted for enclosing a GBIC module therein comprising:

10. The guide rail assembly as claimed in claim 9, wherein the first connector electrically connects with the GBIC module and the second connector electrically connects with the printed circuit board.

11. The guide rail assembly as claimed in claim 10, wherein the frame has a conductive outer surface for providing EMI shielding to the GBIC module.

12. The guide rail assembly as claimed in claim 9, wherein the connector assembly is securely attached to the frame prior to being mounted onto the printed circuit board.

13. The guide rail assembly as claimed in claim 9, further including a pair of poles supporting the frame above the printed circuit board, thereby defining the space under the frame for receiving the second guide rail.

14. A guide rail assembly for receiving a GBIC module therein comprising:

15. The guide rail assembly as claimed in claim 14, further including an electrical connector assembly engageably attached to the frame, the connector assembly having an extension extending downwardly beyond a bottom surface of the frame and electrically mounting to the printed circuit board.

16. The guide rail assembly as claimed in claim 15, wherein the electrical connector assembly includes a printed substrate on which the extension mounts, and a first connector mounting to the printed substrate for electrically connecting with a GBIC module mounted in the frame.

17. The guide rail assembly as claimed in claim 14, further including an electrical connector engageably attached to the frame, the connector having contacts downwardly extending and mounted onto the printed circuit board.

18. The guide rail assembly as claimed in claim 17, wherein the connector has partitioning ribs on opposite sides thereof engageably received in receiving slots defined in inner walls of side beams of the frame.

19. An guide rail system for receiving two electronic modules therein, comprising:

20. The system as recited in claim 19, wherein the second guide rail is positioned between said first guide rail and the printed circuit board, and a portion of said first connector assembly extends vertically through said second frame toward the printed circuit board while without interference against the second connector assembly.
