Description

Technical Field

[0001] The invention relates to a connector assembly, in particular to a connector assembly with a heat sink inside. Background Art

[0002] Chinese invention patent publication number CN104470321 B (corresponding to US patent publication number US9,547,140) discloses a connector, which includes a housing, multiple partitions, at least one heat-conducting device and at least one heat-dissipating device. The housing of the connector includes multiple accommodating units for accommodating plugs, the accommodating units are arranged in at least two rows in the height direction and in at least two columns in the transverse direction, and two adjacent accommodating units in each row in the transverse direction are separated by a partition. The multiple partitions are respectively arranged between two adjacent accommodating units in the height direction. The heat-conducting body of the heat-conducting device is inserted into the interior of the housing from the side wall of the housing and passes through the multiple partitions in the transverse direction, thereby forming a heat-conducting path in the transverse direction. The heat-dissipating device is arranged at the side edges of the heat-conducting body of the heat-conducting device. However, the heat-conducting body of the heat-conducting device of this connector needs to pass through multiple partitions in the transverse direction, so the heat-conducting body is immovable, that is, the heat-conducting body and the heat-dissipating device arranged on the side are fixed and cannot move. For such immovable heat-conducting device and heat-dissipating device, elastic heat-conducting pads and heat-conducting blocks must be added in respective accommodation units to contact respective plugs. Therefore, such heat-conducting device and heat-dissipating device have many structural components, relatively high thermal impedance, and limited heat dissipation capacity. Moreover, all accommodation units including the height direction and the lateral direction are heat-conducting through the path of the same heat-conducting body, which easily makes it impossible for heat to be quickly dissipated and accumulate to generate high temperature.

[0003] Chinese invention patent publication number CN106469878 A (corresponding to US patent publication number US10,153,571) discloses a connector, wherein the cover of the connector includes a middle part, the middle part includes an upper wall and a lower wall, the upper wall and the lower wall define an upper port and a lower port in the cover, and the lower wall includes a hole formed therein so that the middle part is connected to the lower port. The bias heat sink of the connector is arranged in the middle part between the upper port and the lower port, and the bias heat sink extends through the hole and enters the lower port. The bias heat sink of this connector can directly contact the plug to dissipate heat more efficiently, but the bias heat sink is built into the interior of the cover and can only dissipate heat by relying on the air flow introduced into the middle part. Therefore, in application environments with higher frequency transmission, it is expected that these heat dissipation structures can have better heat dissipation capabilities to ensure the stability of the device for long-term operation. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a connector assembly that can improve at least one of the problems in the above-mentioned prior art.

[0005] Therefore, in some embodiments of the connector assembly of the present invention, it includes a guide shielding cover, an external heat sink, a built-in bias heat sink, and two side wing heat sinks. The guide shielding cover includes a cover body and a compartment bracket arranged in the cover body, the cover body has a top wall and two side walls, the compartment bracket has an upper wall and a lower wall that jointly define the inner storage space, and the compartment bracket and the cover body jointly define an upper storage space and a lower storage space, the top wall of the cover body is formed with an upper window connected to the upper storage space, the side wall of the cover body is formed with a side window connected to the inner storage space, and the lower wall of the compartment bracket is formed with a lower window that connects the inner storage space to the lower storage space. The external heat sink is arranged on the top wall of the cover body and passes through the upper window to enter the upper storage space. The built-in bias heat sink is arranged in the compartment bracket and has a built-in heat sink that passes through the lower window to enter the lower storage space, and the built-in heat sink can move along the up and down direction. The two side wing heat sinks are respectively located on the outer sides of the two side walls of the cover body, and the two side wing heat sinks are connected to the built-in heat sink through a connecting structure passing through the side window. The width of the side window in the up and down direction is greater than the width of the connecting structure in the up and down direction, so that the two side wing heat sinks can move along the up and down direction with the built-in heat sink.

[0006] In some embodiments, the connection structure includes a first connection portion formed on the built-in heat sink and a second connection portion formed on the wing heat sink, and the first connection portion and the second connection portion can be locked by a locking member.

[0007] In some embodiments, the connection structure further includes a positioning column and a positioning hole that cooperate with each other and are formed on the first connection portion and the second connection portion.

[0008] In some embodiments, the connection structure further includes a connection layer of a thermally conductive material disposed between the first connection portion and the second connection portion.

[0009] In some embodiments, both the first connecting portion and the second connecting portion are convex structures.

[0010] In some embodiments, the built-in heat sink has a thermal coupling portion that passes through the lower window and enters the lower accommodating space, and the built-in biased heat sink also includes a biasing spring disposed between the built-in heat sink and an upper wall of the compartment bracket.

[0011] In some embodiments, the side wing heat sink has a plate body extending along the corresponding side wall, and heat sink fins formed outward from the plate body, and the built-in heat sink has a base plate, and heat sink fins formed upward from the base plate.

[0012] The movable built-in heat sink of the present invention is connected to the side wing heat sinks on both sides, and the side wing heat sinks are located on the outside of the two side walls of the guide shield, which can guide the heat of the built-in heat sink to the outside of the guide shield, not only increasing the heat dissipation area, but also increasing the interaction with the external air flow to improve the heat dissipation capacity. On the other hand, the present invention is respectively provided with the external heat sink, the built-in bias heat sink and the side wing heat sink connected to the built-in bias heat sink for the upper accommodating space and the lower accommodating space, which can completely improve the overall heat dissipation capacity for each part of the guide shield.

In the present embodiment, the plurality of heat dissipation fins 312, for example, can be arranged on the base plate 311 by welding to avoid the fastener 32, but it should be noted that in a variant embodiment, the plurality of heat dissipation fins 312 can also be formed integrally upward from the base plate 311. The base plate 311 has a thermal coupling portion 311a extending downward and extending through the upper opening window 111a into the upper accommodation space 13. The thermal coupling portion 311a is used to connect with the pluggable module 200 (see FIG. 11 ) inserted into the upper accommodation space 13. Figure 1) to enhance the heat dissipation of the external heat sink 3, and in the present embodiment, the bottom surface of the thermal coupling portion 311a is provided with a thermally conductive interface material 311b for contacting the pluggable module 200, and the thermally conductive interface material 311b can be, for example, a thermally conductive gasket including a phase change material.

The width W1 of the side window 112f in the up-down direction D2 is greater than the width W2 of the connection structure 6 in the up-down direction D2, so that the two side wing heat sinks 5 can move along the up-down direction D2 with the built-in heat sink 41. The two sides of the movable built-in heat sink 41 of the present invention are connected with the side wing heat sinks 5, and the side wing heat sinks 5 are located on the outside of the two side walls 112 of the guide shielding cover 1, which can guide the heat of the built-in heat sink 41 to the outside of the guide shielding cover 1, not only increasing the heat dissipation area, but also increasing the interaction with the external air flow to improve the heat dissipation capacity. On the other hand, the connector assembly 100 is provided with the external radiator 3, the built-in bias radiator 4 and the side wing heat sink 5 connected to the built-in bias radiator 4 for the upper accommodating space 13 and the lower accommodating space 14, respectively, which can completely improve the overall heat dissipation capacity of each part of the guide shielding cover 1.

[0119] In this embodiment, each wing heat sink 5 has a plate body 51 extending along the corresponding side wall 112, and a plurality of heat sink fins 52 formed outward from the plate body 51 along the left-right direction D3 and arranged side by side along the up-down direction D2.

In detail, the positioning column 611 is formed on the first connection part 61, and the positioning hole 621 is formed on the second connection part 62. However, in other embodiments, the positioning column 611 may also be formed on the second connection part 62, and the positioning hole 621 may also be formed on the first connection part 61. In addition, the first connection part 61 and the second connection part 62 are both convex structures, but in other embodiments, the first connection part 61 and the second connection part 62 may also be one convex structure and the other a matching concave structure. The first connection part 61 and the second connection part 62 can be locked by a locking member 63, and the locking member 63 may be a locking element such as a screw, for example. In detail, the connection structure 6 also includes a through hole 64 formed through the plate body 51 of the side wing heat sink 5 and the second connecting part 62 for the locking member 63 to pass through, and a locking hole 65 formed in the first connecting part 61 for the locking member 63 to be screwed in. The locking member 63 passes through the through hole 64 and is screwed in the locking hole 65 to lock the first connecting part 61 and the second connecting part 62.

[0120] In addition, in this embodiment, the connection structure 6 further includes a heat conductive material connection layer 66 disposed between the first connection portion 61 and the second connection portion 62. The heat conductive material connection layer 66 can be, for example, a heat conductive paste or a heat conductive glue, etc., and the heat conductive material connection layer 66 can make the heat conductivity between the first connection portion 61 and the second connection portion 62 better.

[0121] It should be noted that, although in the present embodiment, the base plate 411 and the heat dissipation fins 412 of the built-in heat dissipation element 41 are of an integrated structure, the base plate 411 and the heat dissipation fins 412 of the built-in heat dissipation element 41 may also be of an assembled structure in other embodiments. Similarly, although in the present embodiment, the plate body 51 and the heat dissipation fins 52 of the wing heat dissipation element 5 are of an integrated structure, the plate body 51 and the heat dissipation fins 52 of the wing heat dissipation element 5 may also be of an assembled structure in other embodiments.

[0122] In addition, the front wall 123 of the compartment bracket 12 is formed with a plurality of first front heat dissipation holes 123a, and the sheet 161 of the compartment bracket grounding member 16 is formed with a plurality of second front heat dissipation holes 161a corresponding to the plurality of first front heat dissipation holes 123a. The plurality of first front heat dissipation holes 123a and the plurality of second front heat dissipation holes 161a are connected to the inner storage space 125 so that air flow can more easily enter the inner storage space 125, thereby enhancing the heat dissipation performance of the built-in bias heat sink 4.
