Connector system
There is provided an interface module, including an interface for connection with a signal connector, a cage for guiding the signal connector towards the interface and a heat sink. The cage has a cage portion that is configured to move from a first position to a second position upon insertion of the signal connector into the cage. In the first position, the cage portion is not in thermal contact with the heat sink. When in the second position, the cage portion is in thermal contact with the heat sink.
1. An interface module, comprising:
an interface for connection with a signal connector;
a heat sink;
a cage for guiding the signal connector towards the interface, the cage comprising a cage portion that is configured to move from a first position to a second position upon insertion of the signal connector into the cage, the cage portion being integrally formed with a remainder of the cage;
the cage portion not being in thermal contact with the heat sink when the cage portion is in the first position; and
the cage portion being in thermal contact with the heat sink when the cage portion is in the second position.
2. The interface module according to claim 1 , wherein the cage defines an internal volume and wherein, when in the first position, the cage portion extends into the internal volume.
3. The interface module according to claim 2 , wherein the cage portion is configured such that insertion of the signal connector urges the cage portion outwardly from the internal volume towards the second position.
4. The interface module according to claim 1 , wherein the cage portion is biased towards the first position.
5. The interface module according to claim 4 , wherein the cage portion is biased towards the first position by means of a resilient connection between the cage portion and the cage.
6. The interface module according to claim 1 , wherein the cage further comprises a cage body, and wherein the cage portion is coupled to the cage body and movable relative to the cage body.
7. The interface module according to claim 6 , wherein the cage portion is coupled to the cage body via one edge of the cage portion, with the remaining edges of the cage portion unconnected to the cage body.
8. The interface module according to claim 7 , wherein the one edge coupling the cage portion to the cage body is an edge that is proximal to an opening of the cage through which the signal connector is insertable.
9. The interface module according to claim 8 , wherein the interface is located towards a distal end of the cage relative to the opening.
10. The interface module according to claim 1 , wherein the cage portion comprises a layer of thermal interface material.
11. The interface module according to claim 1 , wherein the heat sink comprises a housing of the interface module.
12. The interface module according to claim 1 , wherein the signal connector is one of: an optical connector, an electrical connector, and an electro-optic connector.
13. The interface module according to claim 1 , wherein the signal connector is a small form-factor pluggable, SFP, connector.
14. An apparatus comprising at least one interface module, each of the at least one interface module having:
an interface for connection with a signal connector;
a heat sink;
a cage for guiding the signal connector towards the interface, the cage comprising a cage portion that is configured to move from a first position to a second position upon insertion of the signal connector into the cage, the cage portion being integrally formed with a remainder of the cage;
the cage portion not being in thermal contact with the heat sink when the cage portion is in the first position; and
the cage portion is in thermal contact with the heat sink when the cage portion is in the second position.
15. The apparatus according to claim 14 , wherein the apparatus comprises a plurality of interface modules,
and the apparatus further comprises an apparatus heat sink.
16. The apparatus according to claim 14 , wherein the cage defines an internal volume and wherein, when in the first position, the cage portion extends into the internal volume.
17. The apparatus according to claim 16 , wherein the cage portion is configured such that insertion of the signal connector urges the cage portion outwardly from the internal volume towards the second position.
18. The apparatus according to claim 14 , wherein the cage portion is biased towards the first position.
19. The apparatus according to claim 18 , wherein the cage portion is biased towards the first position by means of a resilient connection between the cage portion and the cage.
20. The apparatus according to claim 14 , wherein the cage further comprises a cage body, and wherein the cage portion is coupled to the cage body and movable relative to the cage body.
21. The interface module of claim 1 , wherein the cage portion includes a plate extending from a body of the cage at an edge of the cage portion, the plate having disposed thereon a thermal interface material having a thickness sufficient to fill a gap between the heat sink and the plate when the cage portion is in the second position.
22. The apparatus of claim 14 , wherein the cage portion includes a plate extending from a body of the cage at an edge of the cage portion, the plate having disposed thereon a thermal interface material having a thickness sufficient to fill a gap between the heat sink and the plate when the cage portion is in the second position.
