Abstract

A shielding cage of a connector is disclosed. The shielding cage includes an opening defined by four walls and configured to receive a plug of a mating connector, and a plurality of shielding spring sheets held on the four walls, each shielding spring sheet having an inner spring sheet portion located inside the opening and an outer spring sheet portion located outside the opening.

First claim

What is claimed is:

1. A shielding cage of a connector, comprising:
an opening defined by four walls and configured to receive a plug of a mating connector; and
a plurality of shielding spring sheets held on the four walls, each shielding spring sheet having a first end on an inner spring sheet portion located inside the opening and an opposite second end on an outer spring sheet portion located outside the opening, the outer spring sheet portion having a first bending portion disposed along an outer wall of the shielding cage and a second bending portion connected to the first bending portion, the second bending portion extending away from the outer wall of the shielding cage to a free end at the second end of the shielding spring sheet.

2. The shielding cage of the connector according to claim 1 , wherein the first end is fixed onto the shielding cage.

3. The shielding cage of the connector according to claim 2 , wherein the shielding cage is adapted to be held on an installation opening of an apparatus housing via the outer spring sheet portion.

4. The shielding cage of the connector according to claim 3 , wherein the outer spring sheet portion comes into elastic and electrical contact with the shielding cage and the apparatus housing simultaneously.

5. The shielding cage of the connector according to claim 4 , wherein a plurality of first elastic electric-contact points are disposed between the outer spring sheet portion and an outer wall of the shielding cage.

6. The shielding cage of the connector according to claim 5 , wherein a plurality of second elastic electric-contact points are disposed between the outer spring sheet portion and the apparatus housing.

7. The shielding cage of the connector according to claim 6 , wherein the outer spring sheet portion comes into elastic and electrical contact with an inner edge of the installation opening of the apparatus housing and an inner surface of a side wall of the apparatus housing simultaneously.

8. The shielding cage of the connector according to claim 7 , wherein the free end of the outer spring sheet portion comes into elastic and electrical contact with the inner surface of the side wall of the apparatus housing.

9. The shielding cage of the connector according to claim 8 , wherein the first bending portion is pressed between the inner edge of the installation opening of the apparatus housing and the outer wall of the shielding cage.

10. The shielding cage of the connector according to claim 9 , wherein an end of the second bending portion is pressed against the inner surface of the side wall of the apparatus housing.

11. The shielding cage of the connector according to claim 4 , wherein two adjacent side portions of the outer spring sheet portions which belong to two adjacent shielding spring sheets extend toward each other at a corner of the opening, so as to decrease a gap between the two adjacent shielding spring sheets.

12. The shielding cage of the connector according to claim 4 , wherein at least one spacer is provided in the opening to divide the opening into a plurality of plug-in ports.

13. The shielding cage of the connector according to claim 12 , wherein two adjacent side portions of the outer spring sheet portions which belong to two adjacent shielding spring sheets project toward each other at the spacer, so as to decrease a gap between the two adjacent shielding spring sheets.

14. The shielding cage of the connector according to claim 13 , wherein each shielding spring sheet has a connection portion located between the inner spring sheet portion and the outer spring sheet portion and used to connect the inner spring sheet portion to the outer spring sheet portion.

15. The shielding cage of the connector according to claim 14 , wherein the connection portion of the shielding spring sheets is provided at an edge of the opening.

16. The shielding cage of the connector according to claim 15 , wherein a plurality of shielding spring sheets on an upper wall of each plug-in port are connected to each other to form a group of first spring sheets, a plurality of shielding spring sheets on a lower wall of each plug-in port are connected to each other to form a group of second spring sheets, and a plurality of shielding spring sheets on a side wall of each outmost plug-in port are connected to each other to form a group of third spring sheets.
