Abstract

A cassette includes a shell having a housing and a cover mated together to define an inner chamber. The housing has a plurality of plug cavities configure to receive plugs therein. A contact subassembly is received in the inner chamber. The contact subassembly has a circuit board and a plurality of contacts coupled to the circuit board. The contacts are arranged in contact sets that are received in corresponding plug cavities to mate with different corresponding plugs. A latch member couples the housing to the cover. The latch member has a latch element configured to secure the shell to a panel.

Claims

1. A cassette comprising:

a shell having a housing and a cover mated together, the shell defining an inner chamber bounded by the housing and the cover, the housing having a plurality of plug cavities configure to receive plugs therein;

a contact subassembly received in the inner chamber, the contact subassembly having a circuit board and a plurality of contacts coupled to the circuit board, the circuit board housed within the inner chamber, the contacts being arranged in contact sets that are received in the corresponding plug cavities to mate with different corresponding plugs; and

a latch member coupling the housing to the cover, the latch member having a generally planar base spanning the housing and the cover, the base coupled to the housing and the cover, the latch member having a latch element configured to secure the shell to a panel, the latch element being cantilevered from the base and being deflectable toward the base.

2. The cassette of claim 1, wherein the latch member is separate from both the housing and the cover and the latch member is coupled to both the housing and the cover.

3. The cassette of claim 1, wherein the housing includes a rib extending therefrom, the latch member includes a channel that receives the rib to secure the relative position of the latch member with respect to the housing.

4. The cassette of claim 1, wherein the cover includes a rib extending therefrom, the latch member includes a channel that receives the rib to secure the relative position of the latch member with respect to the cover.

5. The cassette of claim 1, wherein the housing includes a trough, the latch member being received within the trough to position the latch member with respect to the housing.

6. The cassette of claim 1, wherein the cover includes a trough, the latch member being received within the trough to position the latch member with respect to the cover.

7. The cassette of claim 1, wherein the housing includes a front flange, and wherein the latch element includes a panel engagement surface, the shell being positioned with respect to the panel such that the panel is captured between the front flange and the panel engagement surface.

8. The cassette of claim 1, wherein the latch member is coupled to either the housing or the cover prior to the cover being coupled to the housing.

9. The cassette of claim 1, wherein the shell defines a box-shaped outer perimeter having a front, a rear, a top, a bottom and opposite sides, the latch member being coupled to a corresponding side of the shell.

10. The cassette of claim 1, wherein the housing includes a front, the plug assemblies being open at the front, the circuit board being received in the inner chamber such that the circuit board is parallel to the front.

11. A cassette comprising:

a shell having a housing and a cover mated together to define an inner chamber, the housing having a plurality of plug cavities configure to receive plugs therein, at least one of the housing and the cover having a locking finger engaging the other one of the housing and the cover to secure the cover to the housing, the locking finger includes a hook configured to be received in an opening to lock the cover to the housing;

a contact subassembly received in the inner chamber, the contact subassembly having a circuit board and a plurality of contacts coupled to the circuit board, the circuit board housed within the inner chamber, the contacts being arranged in contact sets that are received in corresponding plug cavities to mate with different corresponding plugs; and

a latch member separately provided from the housing and the cover, the latch member being separately coupled to both the housing and the cover to secure the cover to the housing.

12. The cassette of claim 11, wherein the locking finger and the latch member operate as back up locking features to one another to secure the cover to the housing when the other of the locking finger and the latch member fail.

13. The cassette of claim 11, wherein the locking finger is engaged substantially simultaneously with the latch member being coupled to the housing and the cover.

14. The cassette of claim 11, wherein the locking finger and the latch member are slidable to a locked position.

15. The cassette of claim 11, wherein the housing includes a rib extending therefrom, the latch member includes a channel that receives the rib to secure the relative position of the latch member with respect to the housing.

16. The cassette of claim 11, wherein the latch member includes a base spanning the housing and the cover, the base being coupled to both the housing and the cover.

17. The cassette of claim 11, wherein the shell defines a box-shaped outer perimeter having a front, a rear, a top, a bottom and opposite sides, the latch member being coupled to a corresponding side of the shell along the outside of both the housing and the cover.

18. A cassette comprising:

a shell having a housing and a cover mated together to define an inner chamber, the housing having a plurality of plug cavities configure to receive plugs therein;

a contact subassembly received in the inner chamber, the contact subassembly having a circuit board and a plurality of contacts coupled to the circuit board, the circuit board housed within the inner chamber, the contacts being arranged in contact sets that are received in corresponding plug cavities to mate with different corresponding plugs; and

a latch member coupling the housing to the cover, the latch member having a generally planar base spanning the housing and the cover, the base coupled to both the housing and the cover, the latch member having a latch element configured to secure the shell to a panel, the latch element being cantilevered from the base and being deflectable toward the base, the latch member extending from either the housing or the cover towards the other of the housing or the cover prior to coupling the cover to the housing, the latch member aligning the cover with the housing as the cover is coupled to the housing.

19. The cassette of claim 18, wherein the cover includes a trough, the latch member being received within the trough to align the cover with the housing.

20. The cassette of claim 18, wherein the shell defines a box-shaped outer perimeter having a front, a rear, a top, a bottom and opposite sides, the latch member being coupled to a corresponding side of the shell and extending along the outside of both the housing and the cover.
