Abstract

An electrical assembly includes a main body on which the cage assembly and the associated main receptacle connector are mounted. The cage is adapted to receive the FP5 plug module or the QSFP-28 plug module associated with an adaptor. The adaptor includes a housing unitarily formed with the heat sink structure and an intermediate receptacle connector mounted upon an intermediate board wherein the intermediate receptacle connector is adapted to receive the QSFP-28 plug module and the intermediate board is adapted to be received with the main board. The cage includes different latches respectively mutually exclusively locking the FP5 plug module and the QSFP-28 plug module.

First claim

What is claimed is:

1. An electrical assembly comprising:
a metallic cage defining a receiving space for receiving a first type plug module;
a main connector located at a rear end of the receiving space; and
an adaptor including an intermediate connector associated with an intermediate board; wherein
the intermediate board is adapted to be mated with the main connector, and the intermediate connector is adapted to be mated with a second type plug module;
said adaptor includes a housing enclosing said intermediate connector and said intermediate board;
the housing comprises an upper housing and a lower housing assembled to each other to commonly sandwich said intermediate connector and said intermediate board therebetween; and
the housing comprise a heat sink located on the upper housing.

2. The electrical assembly as claimed in claim 1 , said adaptor forms two opposite lateral openings.

3. The electrical assembly as claimed in claim 1 , wherein the cage is directly latchable with the second type plug module.

4. The electrical assembly as claimed in claim 1 , wherein the cage comprises a first latch for being latched with the first type plug module, and a second latch for being latched with the second type plug module.

5. The electrical assembly as claimed in claim 4 , wherein the first latch and the second latch are offset in a mating direction of the adaptor, and also offset in a vertical direction.

6. The electrical assembly as claimed in claim 1 , wherein the heat sink is unitarily formed on the upper housing.

7. The electrical assembly as claimed in claim 1 , wherein the heat sink comprises a plurality of ribs and a plurality of slots formed between every two adjacent ribs.

8. The electrical assembly as claimed in claim 7 , wherein the cage defines a plurality of through holes in communication with the slots to establish air flow channels for heat sinking.

9. The electrical assembly as claimed in claim 1 , wherein the housing comprises a mating end opposite to an end of the intermediate connector and the intermediate board, the mating end has a width larger than other portion of the housing.

10. The electrical assembly as claimed in claim 1 , wherein the intermediate connector is surface mounted on the intermediate board.

11. An adaptor, comprising:
a housing having a first end for mating with a cage assembly, an opposite second end for a plug module inserted into, and a body portion having a receiving room disposed therebetween for receiving the plug module; and
a connector unit received in the housing and located on the first end; wherein said connector unit comprises a printed circuit board for mating with the cage assembly, and a connector mounted on the printed circuit board for receiving the plug module; and
the housing defines at least one opening for the plug module to directly latch with the cage assembly.

12. The adaptor as claimed in claim 11 , wherein the housing comprises an upper housing and a lower housing assembled to each other to commonly sandwich said connector unit therebetween.

13. An electrical connector assembly comprising:
a metallic cage forming a receiving space and a main receptacle connector at a rear end for receiving either directly a first type plug module which has a board type mating section directly received within the main receptacle connector, or indirectly a second type plug module through an adaptor wherein the adaptor has an intermediate board with a board type mating section received within the receptacle connector and an intermediate receptacle connector mounted upon the intermediate board for receiving a board type mating section of the second type plug module; wherein
the cage forms a first lock for engagement with a latch of the first type plug module, and a second lock for engagement with an other latch of the second type plug module, said first lock being spaced from the second lock in a front-to-back direction.

14. The electrical connector assembly as claimed in claim 13 , wherein the adaptor includes a housing enclosing the second type plug module.

15. The electrical connector assembly as claimed in claim 14 , wherein the second lock is located behind the first lock in the front-to-back direction.

16. The electrical connector assembly as claimed in claim 14 , wherein a heat sink structure is formed upon the housing.

17. The electrical connector assembly as claimed in claim 14 , wherein the board type mating section of the intermediate board extends forwardly beyond the housing.
