The above aspects and other features are set forth in the following description in conjunction with the drawings.

Referring to Figure 1, a perspective view of an assembly 10 incorporating features of an exemplary embodiment is shown. Although features are described with reference to the exemplary embodiments illustrated in the drawings, it is understood that the features may be embodied in many alternative embodiments. In addition, any suitable size, shape or type of elements or materials may be used.

Assembly 10 includes printed circuit boards 12, 14 (such as, for example, a mother printed circuit board and a sub-printed circuit board), sockets 16, 18, and cable assembly 20. More or less than two printed circuit boards may be provided and one or more of the sockets may be attached to different types of electrical components. In the present example, cable assemblies 20 each include a passive cable assembly 22 that is coupled to active fiber optic cable assembly 24. For example, active fiber optic cable assembly 24 can include an optical sensor. The front end of each of the active cable assemblies 24 is configured to be removably connected to one of the sockets 16, 18 head. However, in alternative embodiments, any suitable components connected to the sockets 16, 18 may be provided.

In the present example, the socket includes two first sockets 16 attached to the top side of the mother printed circuit board 12 and two second sockets 18 attached to the bottom side of the sub-printed circuit board 14. However, in alternative embodiments, more or less than four outlets may be provided and more or less than two types of outlets may be provided. Referring also to Figure 2, only two of the sockets are shown enlarged. In the present example, the sockets 16, 18 are each provided as an integrated cover and heat sink assembly. Each of the sockets 16, 18 has an open front end 26 for receiving the front end of one of the active fiber assemblies 24. The cover portion of the assembly forms a shroud housing that includes the first member 36 and the second member 37.

Referring also to Figure 12, the second member 37 is shown in partial cross-section on the mother printed circuit board 12. A conventional electrical connector 101 is provided on the mother printed circuit board 12 surrounded by the second member 37. The connector 101 includes a housing 28 and electrical contacts 29 that are coupled to the motherboard 12. The second member 37 forms a main cover member. The main shroud member forms an aperture 26 for receiving the plug prior to one of the assemblies 24. The main cover member has a post 104 positioned in the aperture of the motherboard 12. The main shroud member has a top open aperture 106 that enters the receiving area 108. The electrical connector 101 is positioned on the rear of the receiving area 108. The clip 36 can be attached to the tab 60 on the lateral side 39 of the main cover member 37, and the clip 36 can substantially close the top open aperture 106; the heat sink 34 can be positioned on the front of the top open aperture 106.

In the present example, electrical contact 29 has a solder tail extending from the bottom side of housing 28 and mounted in the aperture of female printed circuit board 12. The second socket 18 has a second cover member 30. In the present example, the electrical contacts of the second connector in the second cover member 30 have an extension from the top side of the second cover member 30 and are mounted in the sub-member Solder tail in the hole on the bottom side of printed circuit board 14

Referring also to FIGS. 3 through 4, the motherboard sockets 16 each include a subassembly 32 that includes a heat sink 34 and a member 36. In the present example, the fins 34 are one-piece members having a central section 38 and two lateral end sections 40. The central section 38 has a generally flat beam shape. The lateral end section 40 includes heat transfer fins 42 that extend downward. However, in alternative embodiments, different shapes may be provided for the heat sink, and the heat sink may include a plurality of members. When the sub-assembly 32 is coupled to the second member 37, the lateral end section 40 extends along the lateral side 39 of the second member 37 from the first side 41 toward the opposite second side 43 (see Figures 1, 2 and 12). ).

Referring also to Figures 5-8, member 36 is preferably a piece of member comprised of sheet metal. The member has two primary functions: as at least a portion of the shroud that connects the heat sink 34 to the mechanical connector of the second member 37 and the socket 16. Member 36 includes a front section 44 and a rear section 46. The front section 44 is adapted to be attached to the central section 38 of the heat sink 34. Front section 44 includes lateral ends that form fin bundles 48 and contact projections 50. The straps 48 each include a front hook 52 and a rear tab 54. The heatsink strap holds or holds the heat sink during operation. Member 36 is adapted to prevent the heat sink from becoming stuck during the mating and disengaging of the plug segments of assembly 24 by controlling the position of the heat sinks in all directions. When the member 36 is mated to the heat sink, the strap 48 can limit the leftward and rightward movement of the heat sink 34 on the member 36 by stopping the fins 42 or other protruding features. The fin hooks 52 position the fins in the forward and downward directions by winding the leading edge of the fins. The rear fin tab 54 positions or positions the fin in a rearward direction. The rigidity of the strap may only be sufficient to accommodate and orient the heat sink. They are not intended to provide the required normal force.

Inserting one of the ends of the plug 24 into one of the receptacles 16, 18 causes the assembly 24 to contact the heat sink 34. Thus, the heat sink can help remove heat from the active components in the assembly 24. The heat sink 34 can be pushed up relative to the main cover member 37 by the insertion of the front plug end of the assembly 24. The member 36 or 36' may allow the fins 34 to resiliently move upward relative to the main cover member 37, but remain attached to the main cover member 37. Contact bumps 50 provide a constant contact point during the matching period.

The circular feature on the underside of the contact protrusion 50 allows the fin 34 to pivot during plug end mounting prior to assembly 24 and allows for easier insertion of the plug tip prior to assembly 24. Therefore, the fins 34 can be inclined with respect to the clip 36 on the protrusions 50. This type of adjustability of the fins 34 on the projections 50 can help prevent the fins from becoming stuck with the plug ends prior to the assembly 24 when the assembly 24 is inserted. The leading edge of the fins 34 has a tapered shape to allow the assembly 24 to tilt the front portion of the fin upward when the assembly 24 is inserted. When the fins 34 pivot on the bottom of the projections 50, the rear ends of the fins can move up and down against the tabs 54 and the entire front section 44 is also deflected upwards; the beams 65 are bent to allow this movement.

The rear section 46 has a main portion 56 on the top side 41 of the member 37 and a snap latch or tab 58 extending downwardly from the main portion 56. The latch 58 is configured to be snapped onto the projection 60 on the side of the member 37 (see FIGS. 2 and 12) to securely latch the member 46 rear section 46 to the member 37. In alternative embodiments, any suitable type of connection may be provided.

In the illustrated exemplary embodiment, the front and rear sections of member 36 can be coupled to each other by a central section 62. The central section 62 includes at least one beam 65. The illustrative embodiment shows three of the beams 65 and the holes 66 between the beams. (the Etc.) The beam 65 provides a normal force to the heat sink. The size and shape of the aperture 66 can be customized to provide the normal force of the customized feature, wherein the aperture serves as a feature for adjusting or adjusting the normal force and stress of the assembly. The shape and size can be varied to meet specific needs.

Referring back to Figures 1 through 2, the daughterboard receptacles 18 each include a main cover member 30 and a subassembly 32'. The main cover member 30 is similar to the main cover member 37. However, the main cover member 30 has an opening that substantially closes the bottom side and passes through the top side thereof. The front portion of the opening in the top side is covered by a subassembly 32'. The opening in the top side is followed by an electrical connector (for example, such as 101) mounted to the lower side of the sub printed circuit board 14. The top side of the main cover member 30 includes mounting posts that extend into the apertures through the bottom side of the sub-printed circuit board to mechanically attach the main cover member 30 to the board and electrically connect the main cover member to the ground in the board.

Subassembly 32' includes heat sink 34 and member 36'. The subassembly 32' is identical to the subassembly 32 except that the subassembly 32' has a member 36' other than the member 36. With particular reference to Figure 3, member 36' is identical to member 36 except that the rear portion 46 is removed from line 64. Thus, as shown in Figure 9, the section 36' after the member has only one latch 58 on each lateral side. Additionally, for member 36', front section 44 and central section 62 are identical.

With particular reference to Figure 9, arrow 68 illustrates that heat sink 34 can float up and down on socket 18. Likewise, the heat sink 34 can float on the socket 16. Floating is made possible by the connections provided by the members 36, 36'. The front section 44 is movable relative to the section 46 after the members 36, 36' by the elastic deflection of the beam 65 of the center section 62. Thus, member 36 or 36' acts as a cantilever leaf spring to allow the heat sink to move during the connection of the plug segments of assembly 24.

Using the above examples, for example, a clip can be provided as part of the mask to hold the heat sink on the CXP connector. The clips position the heat sink; provide a specific amount of normal force; provide sufficient travel to allow mating to the plug 24; can be mounted upside down; and serve as standard as possible. The result is a concept that allows sufficient deflection and normal force to the heat sink while capturing and holding the heat sink. This concept has the characteristics of a normal force that allows manufacturers to customize to the application. The members 36 and 36' are adapted to move during the mating and disengaging of the plug of the assembly 24 by allowing the heat sink to move as it is contacted by the assembly 24 and to control the position of the heat sink in all directions as the heat sink moves. Make the heat sink not stuck.

In one type of example as shown in Figure 10, the distance 70 can be approximately 26 mm. In the present example, the distance 72 as shown in Figure 11 can be about 9.9 mm and the distance 74 can be about 38 mm. As shown in Figure 9, the distance 76 between the end of the printed circuit board and the heat sink can be reduced to about 4 mm, which is about 7.5 mm in conventional designs. Moreover, using an exemplary embodiment, the floating distance 78 can provide a total gap of a gap of approximately 1.35 mm (0.60 mm initial height + 0.75 mm float) from the surface of the printed circuit board. These dimensions are for one instance only. In different embodiments, the dimensions may vary.

Using an illustrative embodiment of the present disclosure, a communication connector (such as an optical connector or an electrical connector) can be provided, the communication connector including an electrical connector having a housing and electrical contacts and a receptacle including a cover and a heat sink. The cover member connects the heat sink to the cover. The member is configured to allow the heat sink to move relative to the cover during the mating connector or plug to the communication connector.

In the above example, the lateral end section 40 of the heat sink may extend outward beyond The lateral side of the main cover member. Therefore, most of the heat sink can be positioned at a position other than directly above the main cover member. Therefore, although the lateral occupation area is large, the vertical occupation area can be small. Moreover, while the above examples have sagging heat transfer fins 42, in alternative embodiments, the heat transfer fins may or may otherwise protrude upward. The heat sink 34 can be attached to the clip 36 shown in Figure 3, the clip and the illustrated case being reversed and the central section 38 can also include upwardly extending heat transfer fins. Assembly 32 is depicted as being attached to the top side of the main cover. In an alternate embodiment, the assembly 32 can be attached to the underside of the main cover, such as subsequently protruding the heat transfer fins upward.
