Connector Shell Assembly and Connector

A connector shell assembly includes a shell, a plurality of bottom port heat sinks, and a bottom port liquid cooling plate. The shell has a row of bottom ports and a row of top ports adjacent to each other in a height direction. The shell also has a transverse slot between a top wall of the row of bottom ports and a bottom wall of the row of top ports. The plurality of bottom port heat sinks are each installed on the top wall of each bottom port. The bottom of each bottom port heat sink protrudes into one bottom port and thermally contacts a mating connector inserted into the one bottom port. The bottom port liquid cooling plate inserted into the transverse slot of the shell thermally contacts a top of each bottom port heat sink and cools the bottom port heat sink with a cooling liquid flowing therethrough.

FIELD OF THE INVENTION

The present invention relates to a connector shell assembly and, more particularly, to a connector comprising the connector shell assembly.

BACKGROUND OF THE INVENTION

In the prior art, in order to improve the heat dissipation effect of connectors having multiple rows of ports, a heat sink is usually installed on the top wall of each port of the connector. The heat sink protrudes into the port to make thermal contact with the mating connector inserted into the port. However, in some applications, the specified heat dissipation effect cannot be achieved solely through the heat sink. Consequently, it is necessary to install a liquid cooling plate on the top wall of the top port of the connector, which is in thermal contact with the top of the heat sink on the top port to further improve the heat dissipation effect of the top port. However, in the prior art, there is no liquid cooling plate set up to dissipate heat from the bottom ports, which results in the heat dissipation performance of the bottom ports not meeting the predetermined requirements.

SUMMARY OF THE INVENTION

A connector shell assembly includes a shell, a plurality of bottom port heat sinks, and a bottom port liquid cooling plate. The shell has a row of bottom ports and a row of top ports adjacent to each other in a height direction of the shell. The shell also has a transverse slot between a top wall of the row of bottom ports and a bottom wall of the row of top ports. The plurality of bottom port heat sinks are each installed on the top wall of each bottom port. The bottom of each bottom port heat sink protrudes into one bottom port and thermally contacts a mating connector inserted into the one bottom port. The bottom port liquid cooling plate inserted into the transverse slot of the shell thermally contacts a top of each bottom port heat sink and cools the bottom port heat sink with a cooling liquid flowing through the bottom port liquid cooling plate.

DETAILED DESCRIPTION

An exemplary embodiment of a connector shell assembly is now described with reference to FIGS. 1-11. As shown in FIGS. 10-11, the connector shell assembly comprises a shell 1, a row of bottom port heat sinks 3, and a bottom port liquid cooling plate 2. The shell 1, as shown in FIG. 10, has a row of bottom ports 101 and a row of top ports 102 adjacent to each other in a height direction Z of the shell 1. The shell 1 also has a transverse slot 103, as shown in FIG. 2, located between a top wall 14 of the row of bottom ports 101 and a bottom wall 13 of the row of top ports 102, as shown in FIG. 10. As shown in FIGS. 10-11, the row of bottom port heat sinks 3 are installed on the top wall 14 of the row of bottom ports 101. Bottoms of the row of bottom port heat sinks 3 protrude into the bottom ports 101, for thermal contact with mating connectors inserted into the bottom ports 101. As shown in FIGS. 2, 5-6, and 9-10, the bottom port liquid cooling plate 2 is inserted into the transverse slot 103 of the shell 1. As shown in FIGS. 9-10, the bottom port liquid cooling plate 2 is in thermal contact with the top of the row of bottom port heat sinks 3, to cool the row of bottom port heat sinks 3 with a cooling liquid flowing through the bottom port liquid cooling plate 2. In this way, the heat dissipation performance of the bottom ports 101 can be improved.

As shown in FIGS. 6-7 and 10, the shell 1 has two opposite side walls 12 in the transverse direction X of the shell 1. A protruding tongue 11, as shown in FIGS. 5-8, is formed on the side wall 12 of the shell 1, and a guide groove 21, as shown in FIG. 3, is formed on the top surface of the bottom port liquid cooling plate 2. The protruding tongue 11 is adapted to cooperate with the guide groove 21 to guide the bottom port liquid cooling plate 2 when inserted into the transverse slot 103 along the transverse direction X of the shell 1.

As shown in FIGS. 6-7, the bottom port liquid cooling plate 2 inserted into the transverse slot 103 can be moved relative to the shell 1 along a longitudinal direction Y of the shell 1 between the pre-installation position (the position shown in FIG. 6) and the final installation position (the position shown in FIG. 7). When the bottom port liquid cooling plate 2 is moved from the pre-installation position to the final installation position, the guide groove 21 disengages from the protruding tongue 11 and the protruding tongue 11 presses down on the top surface of the bottom port liquid cooling plate 2, ensuring reliable thermal contact between the bottom port liquid cooling plate 2 and the bottom port heat sink 3.

As shown in FIGS. 8-9 and 11, a locking spring 13a is formed on the bottom wall 13 of the top port 102. As shown in FIG. 6, when the bottom port liquid cooling plate 2 is in the pre-installation position, the locking spring 13a is in the unlocked position that is detached from the guide groove 21 on the bottom port liquid cooling plate 2. As shown in FIG. 7, when the bottom port liquid cooling plate 2 is moved to the final installation position, the locking spring 13a is in the locking position engaged with the guide groove 21 on the bottom port liquid cooling plate 2 to lock the bottom port liquid cooling plate 2 in the final installation position.

As shown in FIGS. 9-11, the shell 1 has at least one partition wall 15 located between its two side walls 12. The shell 1 also has a row of limiting protrusions 23, as shown in FIGS. 4 and 11, corresponding to the row of bottom ports 101 formed on the bottom surface of the bottom port liquid cooling plate 2. When the bottom port liquid cooling plate 2 is in the pre-installation position, the limiting protrusion 23 is in a position that does not interfere with the side wall 12 and partition wall 15 of the shell 1, thereby allowing the bottom port liquid cooling plate 2 to move along the transverse direction X of the shell 1. When the bottom port liquid cooling plate 2 is in the final installation position, the limiting protrusion 23 is in a position that interferes with the side wall 12 and partition wall 15 of the shell 1 to prevent the bottom port liquid cooling plate 2 from being moved along the transverse direction X of the shell 1.

As shown in FIGS. 3-4, the bottom port liquid cooling plate 2 is a single rectangular plate with a predetermined thickness. The bottom port liquid cooling plate 2 has two opposite ends in its length direction (i.e., the transverse direction X of the shell 1) and two opposite sides in its width direction (i.e., the longitudinal direction Y of the shell 1). As shown in FIG. 3, a liquid cooling channel 22 is formed in the bottom port liquid cooling plate 2 to allow the flow of cooling liquid, and two openings 22a are formed on the end face of one end of the bottom port liquid cooling plate 2 to communicate with the liquid cooling channel 22. The two openings 22a are respectively close to both sides of the bottom port liquid cooling plate 2, with one opening serving as the cooling liquid inlet and the other as the cooling liquid outlet.

As shown in FIGS. 1-2, the connector shell assembly further includes two connection pipes 2b, which are respectively connected to two openings 22a on the bottom port liquid cooling plate 2, for connecting the bottom port liquid cooling plate 2 to a cooling circuit. One of the two connection pipes 2b is used as an inlet pipe, and the other is used as an outlet pipe.

As shown in FIGS. 2 and 5, the connector shell assembly further includes two pipe joints 2a, which are respectively connected to the two openings 22a of the bottom port liquid cooling plate 2. As shown in FIG. 2, two connection pipes 2b are respectively connected to the two openings 22a of the bottom port liquid cooling plate 2 through two pipe joints 2a.

The connector shell assembly further includes a top port liquid cooling plate 5, as shown in FIG. 1, and a row of top port heat sinks. The row of top port heat sinks are installed on the top wall of a row of top ports 102, with the bottoms of the row of top port heat sinks protruding into the top ports 102, for thermal contact with the mating connectors inserted into the top ports 102. The top port liquid cooling plate 5 is installed on the top of the shell 1 and the top port heat sinks, and is in thermal contact with the top of the top port heat sinks. A liquid cooling channel is formed in the top port liquid cooling plate 5 to allow the flow of cooling liquid. The liquid cooling channel has inlet and outlet ports for connecting with the inlet and outlet pipes, respectively.

An exemplary embodiment of a connector is now described with reference to FIGS. 1-11. The connector includes the connector shell assembly according to FIGS. 1-11, and two rows of terminal modules 7 (e.g., like the terminal modules 7 shown in FIG. 20). Two rows of terminal modules 7 are installed into the shell 1 and correspond to a row of bottom ports 101 and a row of top ports 102, respectively. Each terminal module 7 has an insulator 71 and terminals 72 arranged within the insulator 71 (see FIG. 20). The terminals 72 mate with the mating terminal of the inserted mating connector.

The connector further comprises a circuit board 4 (e.g., like the circuit board 4 shown in FIGS. 19 and 20). The bottom of the shell 1 is fixed to the circuit board 4, and the terminal 72 is electrically connected to the circuit board 4.

Another exemplary embodiment of a connector shell assembly is now described with reference to FIGS. 12-15. The main difference between the embodiment shown in FIGS. 12-15 and the embodiment shown in FIGS. 1-11 is the size and structure of the bottom port liquid cooling plate 2 and the transverse slot 103.

As shown in FIG. 14, the bottom port liquid cooling plate 2 includes a pair of strip-shaped bodies 210, a pair of thin plate parts 220, and an end body 230. The pair of strip-shaped bodies 210 are opposite in the width direction of the bottom port liquid cooling plate 2 (i.e., the longitudinal direction Y of the shell 1) and extend along the length direction of the bottom port liquid cooling plate 2 (i.e., the transverse direction X of the shell 1). The pair of thin plate parts 220 are located between the pair of strip-shaped bodies 210 and are respectively connected to the pair of strip-shaped bodies 210. The end body 230 extends along the width direction of the bottom port liquid cooling plate 2 and is connected to one end of the pair of strip-shaped bodies 210 and the pair of thin plate parts 220. A thickness of the pair of strip-shaped bodies 210 and the end body 230 is greater than a thickness of the pair of thin plate parts 220. The pair of thin plate parts 220 are spaced opposite each other in the width direction of the bottom port liquid cooling plate 2, and are used for thermal contact with the top of a row of bottom port heat sinks 3, as shown in FIG. 15.

As shown in FIG. 14, a liquid cooling channel 22 is formed in the pair of strip-shaped bodies 210 and the end body 230 to allow the flow of cooling liquid. Two openings 22a are formed on the end faces of the other ends of the pair of strip-shaped bodies 210, which are connected to the liquid cooling channel 22.

The thin plate part 220, as shown in FIG. 17, extends along the length direction of the bottom port liquid cooling plate 2 at the other side in the width direction of the bottom port liquid cooling plate 2. The thickness of the thick plate part 240 is greater than that of the thin plate part 220, and one side of the thin plate part 220 is connected to one side of the thick plate part 240. The thin plate part 220 is used for thermal contact with the top of a row of bottom port heat sinks 3.
