Description

Technical Field

[0001] This application relates to a liquid-cooled heat dissipation bridge assembly, a heat dissipation shielding cage assembly, and an electrical connector assembly. Background Technology

[0002] A common challenge faced by electrical system developers is thermal management. Heat generated by electronic components within a system can degrade their performance and even damage system components, such as electrical connectors. Electrical connectors are generally used to transmit data and / or power between different systems or devices. Data signals can be transmitted via (multiple) communication cables in the form of optical and / or electrical signals. Examples include IC connectors (PGA, etc.), I / O connectors (DisplayPort, VGA, DVI, HDMI, USB, etc.), fiber optic connectors (FC, SC, ST, LC, D4, DIN, MU, MT, etc.), optical communication connectors (SFP, QSFP, OSFP, etc.), filter connectors, CATV connectors, backplane connectors, memory module / memory connectors (DDR, SIMM, DIMM, PCI, SIM, etc.), high-definition television connectors (RF coaxial connectors, etc.), flexible circuit board connectors (FPC, FFC, etc.), network cable connectors (RJ45, etc.), audio / video (AV) connectors, battery connectors, and so on. Electrical connectors generate significant amounts of heat due to the increasing power requirements.

[0003] To dissipate heat, systems typically include thermal components, such as thermal bridges, which connect to a heat source, absorb heat from it, and transfer it away. However, the heat transfer efficiency of thermal bridges in existing electrical connectors is relatively low. For example, the solution disclosed in Chinese Utility Model Patent CN213959261U involves assembling a heat sink (thermal bridge) on a shielding cage, achieving heat transfer through contact between the heat sink and the inserted mating connector. However, the heat sink alone has limited heat dissipation efficiency and cannot meet the high-speed / high-functionality development requirements of modern electrical connectors.

In the illustrated embodiment of this application, the metal shielding cage 6 is provided with upper and lower double-layer docking spaces 60, and a partition space 100 is reserved in the middle of the upper and lower docking spaces 60.

The side surface of the first bridge portion 21 away from the second bridge portion 22 in the vertical direction is defined as a mating surface 211. The mating surface 211 is mated with the mating surface 103 to achieve heat conduction. In some preferred embodiments, a paste-like thermal interface material can be added between the mating surface 211 and the mating surface 103 to reduce contact thermal resistance and improve heat conduction efficiency, such as thermal paste / heat dissipation paste. The limiting portion 23 restricts the first bridge portion 21 and the second bridge portion 22 to allow one of them to float relative to the other in the vertical direction. The second bridge portion 22 is formed with a boss portion 221 that protrudes at least partly through the clearance hole 610 into the mating space 60 (refer to reference).

The first surface 110 of the mother plate 11 is recessed inward to form the liquid cooling cavity 10 and an opening. The cover plate 12 covers the side of the first surface 110 and seals the opening of the liquid cooling cavity 10. The mating surface 103 is formed by the cover plate 12 facing away from the outer surface of the liquid cooling cavity 10. The mother plate 11 includes a flat main body 111 and side portions 112 extending vertically from the two ends of the main body 111 in the left-right direction. The liquid cooling cavity 10 is formed on the main body 111. The inlet 101 and outlet 102 are respectively formed on two different side portions 112. In the illustrated embodiment of this application, the first liquid-cooled heat dissipation bridge assembly A includes only one liquid cooling plate assembly 1 and multiple heat dissipation bridge assemblies 2.

The elastic limiting bridge 3 has a first fixed segment 31, a second fixed segment 32, and an elastic segment 33 integrally connecting the first fixed segment 31 and the second fixed segment 32.

The first fixed segment 31 is fixedly connected to the first bridge part 21, and the second fixed segment 32 is fixedly connected to the second bridge part 22. In a preferred embodiment, both the first fixed segment 31 and the second fixed segment 32 are elongated strip-shaped structures.

[0048] In a preferred embodiment, a first embedding groove 210 is formed by a recess at one end edge of the first bridge portion 21, and a second embedding groove 220 is formed by a recess at one end edge of the second bridge portion 22.

Similarly, a first embedding groove 210 is formed by a recess at the other end edge of the first bridge portion 21, and a second embedding groove 220 is formed by a recess at the other end edge of the second bridge portion 22. The first fixing segment 31 of the corresponding elastic limiting bridge 3 is implanted and fixed in the first embedding groove 210; the second fixing segment 32 of the corresponding elastic limiting bridge 3 is implanted and fixed in the second embedding groove 220. That is to say, there are two elastic limiting bridges 3, and the two elastic limiting bridges 3 are respectively installed at both ends of the first bridge portion 21 and the second bridge portion 22 in the front-rear direction.

[0049] In a preferred embodiment, the elastic segment 33 includes an elastic body 331 and a first connecting segment 332 and a second connecting segment 333 that integrally connect the elastic body 331 to the first fixed segment 31 and the second fixed segment 32, respectively.

The elastic body 331 includes two elastic arms 3311 that are opposite to each other and spaced apart in the vertical direction, and two connecting portions 3312 that integrally connect the two ends of the two elastic arms 3311. The first connecting segment 332 connects one of the elastic arms 3311 to the first fixed segment 31. The second connecting segment 333 connects the other elastic arm 3311 to the second fixed segment 32. Of course, in other alternative embodiments, the elastic body 331 can also be designed as an S-shape, a Z-shape, or even a horizontally placed M-shape.

[0050] Furthermore, the heat dissipation bridge assembly 2 also includes a first side stop 41 and a second side stop 42.

The second side stop 42 is disposed on the other side of the first bridge portion 21 and the second bridge portion 22, and a second limiting hole 420 is formed through both ends of the second side stop 42 in the front-rear direction. One end of the first fixing segment 31 and the second fixing segment 32 of each elastic limiting bridge 3 is inserted into the first limiting hole 410 of the first side stop 41 in the left-right direction and further extends to form a first barb portion 301 that abuts on the outer surface of the first side stop 41; the other end of the first fixing segment 31 and the second fixing segment 32 of each elastic limiting bridge 3 is inserted into the second limiting hole 420 of the second side stop 42 and further extends to form a second barb portion 302 that abuts on the outer surface of the second side stop 42. The first bridge portion 21 and the second bridge portion 22 are enclosed and limited by the fixed cooperation of the two elastic limiting bridges 3, the first side stop 41 and the second side stop 42.

[0053] The locking part 52 is respectively locked to the first side stop 41 and the second side stop 42 (it can be fixed by welding, adhesive, or snap-fit). In a preferred embodiment of this application, each locking part 52 includes two elastic arms 521 formed by bending downward from the end of the main body 51. The two elastic arms 521 are spaced apart to form an elastic clearance gap 520. The free ends of the two elastic arms 521 further extend in a direction away from each other to form a hook part 522. The upper edge of the first side stop 41 extends outward in the left-right direction to form a first ear 411. The first ear 411 passes through in the up-down direction to form a first locking hole 412. The upper edge of the second side stop 42 extends outward in the left-right direction to form a second ear 421. The second ear 421 passes through in the up-down direction to form a second locking hole 422. The two locking portions 52 of the locking fastener 5 are respectively inserted into the first locking hole 412 and the second locking hole 422, and the hook portions 522 are respectively hooked onto the lower surfaces of the first ear portion 411 and the second ear portion 421. In addition, in a preferred embodiment of this application, both the first side stop 41 and the second side stop 42 are fixed to the liquid cooling plate assembly 1. Specifically, this can be achieved by extending locking wing pieces 401 on the first side stop 41 and the second side stop 42. The locking wing pieces 401 can fit against the surface of the boss portion 122 and be locked by bolts, welding or adhesive.

[0054] Please refer to the reference. Figures 7 to 12 As shown, the first bridge portion 21 is formed by stacking and fixing several first metal sheets 201 in the left-right direction. A grid portion 202 is formed on the surface of the first bridge portion 21 facing the second bridge portion 22. In one embodiment, the grid portion 202 is mainly formed by any two adjacent first metal sheets 201 having different widths in the vertical direction. The second bridge portion 22 is formed by stacking and fixing several second metal sheets 203 in the left-right direction. A mating grid portion 204 is formed on the surface of the second bridge portion 22 facing the first bridge portion 21. Similarly, in another embodiment, the grid portion 202 is mainly formed by any two adjacent first metal sheets 201 having different widths in the vertical direction. The grid portion 202 and the mating grid portion 204 are staggered and meshed to achieve heat transfer. Of course, in other embodiments, the first bridge portion 21 can be formed by milling a single piece of metal, or it can be obtained by die casting of metal powder. In a preferred embodiment of this application, the grille portion 202 is provided with at least three segments, which are respectively located near the front end, middle, and rear end of the first bridge portion 21 in the front-rear direction. The mating grille portion 204 is provided with at least three segments, which are respectively located near the front end, middle, and rear end of the second bridge portion 22 in the front-rear direction.

[0055] Furthermore, the overall structure of the second liquid-cooled heat dissipation bridge assembly B is basically the same as that of the first liquid-cooled heat dissipation bridge assembly A, and will not be described in detail. In addition, in this embodiment, the second liquid-cooled heat dissipation bridge assembly B and the first liquid-cooled heat dissipation bridge assembly A are stacked and fixed on both sides. Specifically, the side 112 of the first liquid-cooled heat dissipation bridge assembly A is stacked and fixed with the side 112 of the second liquid-cooled heat dissipation bridge assembly B. The two can be fixed by bolts, adhesive, or even welding.

[0056] The liquid-cooled heat dissipation bridge assembly described above can also be used with at least one connector module to form a complete electrical connector assembly. The connector module has an insulating body and a plurality of conductive terminals that are at least partially fixed to the insulating body. The metal shielding cage 6 of the heat dissipation shielding cage assembly is correspondingly arranged around the outer periphery of the connector module. The connector module is located at the other end of the mating space 60 away from the opening end in the front-back direction.

[0057] In this embodiment of the application, the docking space 60 formed by the metal shielding cage 6 can be designed in the form of a row of multiple docking spaces, in which case only one first liquid-cooled heat dissipation bridge component A needs to be set; of course, it can also be designed in the form of only one docking space 60. Similarly, the width of the first liquid-cooled heat dissipation bridge component A can be appropriately reduced.

[0058] The proposed solution achieves stronger heat sweeping performance, has a simple overall structure that is easy to implement and mass-produce, and exhibits strong overall structural stability.
