Abstract

Apparatuses and associated methods of manufacturing are described that provide a cage receptacle assembly configured to receive a cable connector. The cage receptacle assembly includes a cage body defining a first end and a second end. The cage body includes a top cage member attached to a bottom cage member via two side portions of the top cage member, and the bottom cage member defines an opening. The cage receptacle assembly defines a heat dissipation unit disposed within the opening of the bottom cage member, and the heat dissipation unit includes one or more heat dissipation elements allowing heat to be transferred from the cable connector to an external environment of the cage receptacle assembly.

First claim

What is claimed is:

1. A cage receptacle assembly configured to receive a cable connector, the cage receptacle assembly comprising:
a cage body defining a first end and a second end, wherein the cage body comprises:
a top cage member defined by a top portion and two side portions, wherein the top cage member defines a top opening, and
a bottom cage member attached to the top cage member via the two side portions of the top cage member, wherein the bottom cage member defines a bottom opening, and wherein the cage body defines a receiving space configured to at least partially receive the cable connector therein via the first end such that a top surface of the cable connector is disposed proximate the top cage member and associated top opening and a bottom surface of the cable connector is disposed proximate the bottom cage member and associated bottom opening, wherein the second end is configured to be received by a datacenter rack for enabling signals to pass between the cable connector that is at least partially received therein and the datacenter rack;

a heat dissipation unit disposed within the top opening of the cage body, and
a heat dissipation unit disposed within the bottom opening of the cage body,
wherein each heat dissipation unit further comprises one or more heat dissipation elements configured to allow heat to be transferred from the cable connector that is at least partially received within the receiving space to an external environment of the cage receptacle assembly.

2. The cage receptacle assembly according to claim 1 , further comprising a printed circuit board assembly disposed adjacent the bottom cage member, wherein the printed circuit board assembly defines a corresponding opening configured to substantially align with the opening defined by the bottom cage member.

3. The cage receptacle assembly according to claim 2 , wherein the heat dissipation unit disposed within the opening defined by the bottom cage member is further configured to be disposed within the corresponding opening of the printed circuit board assembly.

4. The cage receptacle assembly according to claim 3 , wherein the heat dissipation unit of the bottom opening is dimensioned such that, when disposed within the corresponding opening of the printed circuit board assembly, contact between the heat dissipation unit and the printed circuit board assembly is precluded.

5. The cage receptacle assembly according to claim 1 , wherein in an instance in which the cable connector is at least partially received within the cage body, the cage receptacle assembly is further configured such that the heat dissipation unit of the bottom opening contacts the cable connector.

6. The cage receptacle assembly according to claim 1 wherein the bottom cage member is integral to the top cage member.

7. The cage receptacle assembly according to claim 1 , wherein the one or more heat dissipation elements disposed within the bottom opening comprise fins.

8. The cage receptacle assembly according to claim 7 , wherein the fins are disposed substantially perpendicular with respect to the bottom cage member.

9. The cage receptacle assembly according to claim 1 , wherein the heat dissipation unit of the bottom opening comprises a first set of heat dissipation elements having a first height, and a second set of heat dissipation elements having a second height, wherein the second height of the second set of heat dissipation elements is greater than the first height of the first set of heat dissipation elements such that a portion of the second set extends through a plane defined by an inner surface of the heat dissipation unit corresponding to a location of the first set of heat dissipation elements.

10. The cage receptacle assembly according to claim 1 , wherein the one or more heat dissipation elements of the heat dissipation units of the top opening comprise fins.

11. The cage receptacle assembly according to claim 10 , wherein the one or more heat dissipation elements are longitudinal fins disposed along a length of the heat dissipation unit.

12. The cage receptacle assembly according to claim 1 , wherein the cable connector is a quad small form-factor pluggable cable connector.

13. A method of manufacturing a cage receptacle assembly configured to receive a cable connector, the method comprising:
providing a top cage member defined by a top portion and two side portions, wherein the top cage member defines a top opening;
providing a bottom cage member defining a bottom opening;
attaching the bottom cage member to the top cage member via the two side portions of the top cage member to form a cage body defining a first end and a second end, wherein the cage body defines a receiving space configured to at least partially receive a cable connector therein via the first end such that a top surface of the cable connector is disposed proximate the top cage member and associated top opening and a bottom surface of the cable connector is disposed proximate the bottom cage member and associated bottom opening, wherein the second end is configured to be received by a datacenter rack for enabling signals to pass between the cable connector that is at least partially received therein and the datacenter rack;
disposing a heat dissipation unit within the top opening of the cage body, and
disposing a heat dissipation unit within the bottom opening of the cage body,
wherein each heat dissipation unit comprises one or more heat dissipation elements configured to allow heat to be transferred from the cable connector that is at least partially received within the receiving space to an external environment of the cage receptacle assembly.

14. The method of manufacture according to claim 13 , further comprising disposing a printed circuit board assembly adjacent the bottom cage member, wherein the printed circuit board assembly defines a corresponding opening configured to substantially align with the opening defined by the bottom cage member.

15. The method of manufacture according to claim 14 , wherein the printed circuit board assembly adjacent the bottom cage member is configured such the heat dissipation unit disposed within the opening defined by the bottom cage member is disposed within the corresponding opening of the printed circuit board assembly.

16. The method of manufacture according to claim 15 , wherein the heat dissipation unit of the bottom opening is dimensioned such that, when disposed within the corresponding opening of the printed circuit board assembly, contact between the heat dissipation unit and the printed circuit board assembly is precluded.

17. The method of manufacture according to claim 13 , wherein in an instance in which the cable connector is at least partially received within the cage body, the cage receptacle assembly is further configured such that the heat dissipation unit of the bottom opening contacts the cable connector.

18. The method of manufacture according to claim 13 , wherein the heat dissipation unit of the bottom opening comprises a first set of heat dissipation elements having a first height, and a second set of heat dissipation elements having a second height, wherein the second height of the second set of heat dissipation elements is greater than the first height of the first set of heat dissipation elements such that a portion of the second set extends through a plane defined by an inner surface of the first set of heat dissipation elements.

19. A cage receptacle assembly configured to receive a cable connector, the cage receptacle assembly comprisi
