This application claims the benefit of Chinese Patent Application No. CN202310721621.8 filed on Jun. 16, 2023, in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.
Embodiments of the present disclosure relate to a connector shielding shell, and a shell part for assembling the connector shielding shell. The present disclosure also relates to a connector shielding shell assembly comprising the connector shielding shell, and a connector comprising the connector shielding shell assembly.
In the prior art, a high-speed connector generates a large amount of heat. Accordingly, the connector typically requires the installation of finned heat sink on a top wall of an outer shielding shell (usually referred to as the iron cage) of the connector. However, for high-speed connector with multiple chambers, it is necessary to install thermal pads, thermal bridges, cooling plates, and cooling pipes on the outer connector shielding shell to further improve heat dissipation performance. The existing cooling scheme requires numerous components, which increases the contact thermal resistance and leads to a decrease in heat dissipation performance. In addition, in the prior art, it is necessary to install cooling plates and cooling pipes on the side of the outer shielding shell. This occupies a side space of the outer shielding, resulting in a decrease in the layout density of the chambers.
According to an embodiment of the present disclosure, a connector shielding shell includes a bottom shell and a top shell. The top shell has a top wall having a predetermined thickness. An installation opening is formed on or in the top wall and is adapted to receive a cooling pipe. The top shell defines a cooling plate adapted to transfer heat to the cooling pipe.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown to simplify the drawing.
According to an embodiment of the present disclosure, a connector shielding shell comprises a bottom shell and a top shell which includes a top wall with a predetermined thickness. An installation slot or an installation hole is formed on or in the top wall of the top shell for installing a cooling pipe. The top shell is used as a cooling plate to transfer heat to a cooling pipe.
According to another embodiment, a connector shielding shell comprises multiple shell parts which are assembled. At least one shell part is formed with an installation slot or an installation hole for installing a cooling pipe. In this way, the at least one shell part is used as a cooling plate to transfer heat to the cooling pipe.
According to embodiment, a connector shielding shell assembly comprises the above connector shielding shell, and a cooling pipe which is installed in the installation slot or the installation hole of the connector shielding shell.
In another embodiment of the present disclosure, a connector comprises the above connector shielding shell assembly, and multiple terminal modules. The multiple terminal modules are respectively installed in multiple chambers of the connector shielding shell and are adapted to mate and connect with mating connectors inserted into the chambers.
The disclosure also includes a shell part for assembling a connector shielding shell. An installation slot or an installation hole is formed on or in the shell part for installing a cooling pipe. The shell part is adapted for use as a cooling plate to transfer heat to the cooling pipe.
As shown in
The thickness of the top wall 10 of the top shell 1 is greater than a diameter of the cooling pipe 6. The installation slot 101 is formed on the outer surface of the top wall 10 of the top shell 1, which extends along a transverse direction X of the connector shielding shell. The cross-section of the installation slot 101 is U-shaped. The depth of the installation slot 101 is not less than the diameter of the cooling pipe 6, so that the cooling pipe 6 can be completely buried or arranged within the installation slot 101.
In the illustrated embodiments, the top housing 1 can be detachably assembled on the bottom shell 2. The connector shielding shell also includes a vertical partition plate 4, which is set between the top shell 1 and the bottom shell 2 and extends along the longitudinal direction Y and the height direction Z of the connector shielding shell. The vertical partition plate 4 is used to separate the space between the top shell 1 and the bottom shell 2 into multiple chambers 103 arranged side by side in the transverse direction X of the connector shielding shell. In the illustrated embodiment, the connector shielding shell has a single layer of chambers 103.
The top shell 1 also has two first side walls 11 opposite to each other in the transverse direction X of the connector shielding shell, and a first connection column 110 is formed on each of the two first side walls 11. The bottom shell 2 includes a bottom wall and two second side walls 21 opposite to each other in the transverse direction X of the connector shielding shell, and a second connection column 210 is formed on each of the two second side walls 21. A threaded hole 102 is formed in each of the first connection column 110 and the second connection column 210, so that the top shell 1 and the bottom shell 2 can be tightened together by a screw screwed into the threaded holes 102.
A first convex rib 12 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of the top shell 1. A second convex rib 22 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of the bottom shell 2. The first convex rib 12 and the second convex rib 22 are located in the middle of the transverse direction X of the connector shielding shell. A threaded hole 102 is formed in each of the first convex rib 12 and the second convex rib 22, so that the top shell 1 and the bottom shell 2 can be tightened together by a screw screwed into the threaded holes 102. In this way, the top shell 1 and bottom shell 2 can be more reliably fixed together to prevent separation in the middle of the top shell 1 and bottom shell 2.
In the illustrated embodiments, an insertion slot 104 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of each of the top shell 1 and the bottom shell 2. The upper and lower sides of the vertical partition plate 4 are respectively inserted into the insertion slots 104 on the top shell 1 and the bottom shell 2 to fix the vertical partition plate 4 to the top shell 1 and the bottom shell 2.
The connector shielding shell further comprises multiple thermal conductive components 13. The thermal conductive components 13 are respectively arranged in multiple chambers 103 and welded to the inner side of the top shell 1. The thermal conductive component 13 protrudes from the inner side of the top shell 1 to a predetermined height for thermal contact with a mating connector (not shown) inserted into the chamber 103. Thermal conductive component 13 can be a thermal bridge with excellent thermal conductivity performance.
The chamber 103 has an insertion port that allows for the insertion of the mating connector. The connector shielding shell also includes a shielding spring 5. The shielding spring 5 is installed on the peripheral wall of the insertion port of the chamber 103 and is used for electrical contact with a shielding shell of the mating connector.
Still referring to
In another exemplary embodiment of the present disclosure, a connector is also disclosed. The connector includes the aforementioned connector shielding shell assembly and multiple terminal modules. The multiple terminal modules are respectively installed in multiple chambers 103 of the connector shielding shell for mating and connecting with the mating connectors inserted in the chambers 103.
In an exemplary embodiment of the present disclosure, a connector shielding shell mainly includes a top shell 1, a bottom shell 2, and an intermediate shell 3. The top shell 1 includes a top wall 10 with a predetermined thickness. On the top wall 10 of the top shell 1, an installation slot 101 is formed for installing the cooling pipe 6. Therefore, the top shell 1 is used as a cooling plate to transfer heat to the cooling pipe 6.
The intermediate shell 3 is provided between the top shell 1 and the bottom shell 2 to separate the space between the top shell 1 and the bottom shell 2 into adjacent multi-layer spaces in the height direction Z of the connector shielding shell. The intermediate shell 3 has a horizontal partition wall 30 that separates adjacent two layers of space, and an installation slot 101 or an installation hole 101′ is formed on or in the horizontal partition wall 30 of the intermediate shell 3 for installing the cooling pipe 6. The intermediate shell 3 is used as a cooling plate to transfer heat to the cooling pipe 6.
As the cooling plates are directly integrated on the top shell 1 or the intermediate shell 3, embodiments of the present disclosure reduce the number of cooling components, reduce contact thermal resistance, and improve the heat dissipation performance of the connector. In addition, the cooling pipes 6 is installed on the top shell 1 or the intermediate shell 3, so it does not need to occupy the side space of the connector shielding shell. This improves the layout density of the chambers 103 in the connector shielding shell.
A thickness of the horizontal partition wall 30 of the intermediate shell 3 is greater than the diameter of the cooling pipe 6. An installation slot 101 is formed on the horizontal partition wall 30 of the intermediate shell 3, which extends along the transverse direction X of the connector shielding shell. The cross-section of the installation slot 101 is U-shaped, and the depth of the installation slot 101 is not less than the diameter of the cooling pipe 6. In this way, the cooling pipe 6 can be completely buried or contained in the installation slot 101.
In the illustrated embodiments, the top shell 1, the intermediate shell 3, and the bottom shell 2 can be detachably assembled by stacking them above and below. The connector shielding shell also includes a vertical partition plate 4, which is set in each layer of the multi-layer space and extends along the longitudinal direction Y and the height direction Z of the connector shielding shell. The vertical partition plate 4 is used to divide each layer of space into multiple chambers 103 arranged side by side in the transverse direction X of the connector shielding shell.
The top shell 1 also has two first side walls 11 opposite to each other in the transverse direction X of the connector shielding shell. A first connection column 110 is formed on each of the two first side walls 11. The bottom shell 2 includes a bottom wall and two second side walls 21 opposite to each other in the transverse direction X of the connector shielding shell, and a second connection column 210 is formed on each of the two second side walls 21. The intermediate housing 3 also has two third side walls 31 opposite to each other in the transverse direction X of the connector shielding shell. A third connection column 310 is formed on each of the two third side walls 31. A threaded hole 102 is formed in each of the first connection column 110, the second connection column 210 and the third connection column 310, so that the top shell 1, the bottom shell 2 and the intermediate shell 3 can be tightened together by a screw screwed into the threaded holes 102.
A first convex rib 12 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of the top shell 1. A second convex rib 22 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of the bottom shell 2. A third convex rib 32 extending along the longitudinal direction Y of the connector shielding shell is formed on the inner side of the intermediate housing 3. The first convex rib 12, the second convex rib 22 and the third convex rib 32 are located in the middle of the transverse direction X of the connector shielding shell, and a threaded hole 102 is formed on each of the first convex rib 12, the second convex rib 22 and the third convex rib 32, so that the top shell 1, the bottom shell 2 and the intermediate shell 3 can be tightened together by a screw screwed into the threaded holes 102.
Insertion slots 104 extending along the longitudinal direction Y of the connector shielding shell are formed on the inner sides of the top shell 1, the bottom shell 2 and the intermediate shell 3, respectively. The side edges of the vertical partition plate 4 are inserted into the insertion slots 104 to fix the vertical partition plate 4.
The connector shielding shell further comprises multiple thermal conductive components 13, which are respectively arranged in multiple chambers 103 of the connector shielding shell. The thermal conductive components 13 located in the top layer of chambers 103 are welded to the inner side of the top shell 1 and protrude at a predetermined height from the inner side of the top shell 1 for thermal contact with the mating connectors inserted into the top layer of chambers 103. The thermal conductive component 13 located in other chambers 103 except for the top layer of chambers 103 are welded to the inner side of the intermediate shell 3 facing the bottom shell 2 and protrude at a predetermined height from the inner side of the intermediate shell 3 for thermal contact with the mating connectors inserted into other chambers 103.
In the illustrated embodiments, the chamber 103 has an insertion port that allows for the insertion of the mating connector. The connector shielding shell also includes a shielding spring 5.
