[0071] The housing 120 includes a bottom plate 122 and a top plate 123 arranged on both sides of the first accommodating cavity 150. Generally, the housing 120 is regarded as a cube, and the bottom plate 122 and the top plate 123 can be located on the surface with the largest area of the cube. Figure 6 Fig. 7 is a bottom structural schematic diagram of a light cage subassembly 100 according to an embodiment of the present application. As shown in Figure 4 to 6 Fig. 8, in an embodiment, the light cage subassembly 100 includes a first heat sink 130, and the bottom plate 122 has a first hollow structure 1221, and the first heat sink 130 is installed on the side of the bottom plate 122 away from the top plate 123. In the state that the light module 300 is installed in the first accommodating cavity 150, the first heat sink 130 is in heat conduction connection with the light module 300 through the first hollow structure 1221. Thus, the light module 300 can be cooled from the side of the bottom plate 122, and this scheme is beneficial to improve the cooling efficiency and cooling capacity of the light module 300, so as to improve the speed and density of the transmission signal of the light module 300.

[0072] In specific embodiments, the first heat sink 130 can be arranged in contact with the optical module 300 through the first hollow structure 1221, for example, a partial region of the first heat sink 130 is located in the first hollow structure 1221. Alternatively, in an embodiment, a heat-conducting structure, for example, an elastic heat-conducting structure, can be arranged on the side of the first heat sink 130 facing the top plate 123, and the first heat sink 130 is in heat-conducting connection with the optical module 300 through the heat-conducting structure, so as to improve the heat-conducting efficiency of the first heat sink 130 and the optical module 300 and improve the heat dissipation effect of the optical module 300.

[0073] Figure 7 FIG. 1 is a structural schematic diagram of an optical cage subassembly 100 according to an embodiment of the present application, Figure 8 FIG. 2 is an exploded structural schematic diagram of the optical cage subassembly 100 according to an embodiment of the present application, as shown in Figure 7 and Figure 8 In an embodiment, the optical cage subassembly 100 further includes a circuit board 140. The bottom plate 122 of the shell 120 is fixed to the circuit board 140, and the circuit board 140 includes a second hollow structure 141. The orthographic projection of the first hollow structure 1221 on the circuit board 140 at least partially overlaps the second hollow structure 141. The first heat sink 130 is located on the side of the circuit board 140 facing away from the shell 120, and the first heat sink 130 is in heat-conducting connection through the first hollow structure 1221 and the second hollow structure 141. In specific embodiments, the first hollow structure 1221 and the second hollow structure 141 are arranged in a penetrating manner, that is, the first heat sink 130 can be in heat-conducting connection with the optical module 300 through the first hollow structure 1221 and the second hollow structure 141, thereby dissipating heat for the optical module 300.

[0074] In a specific embodiment, the first hollow structure 1221 and the second hollow structure 141 can have the same shape and area, and are arranged in a directly opposite manner, that is, the orthographic projection of the first hollow structure 1221 on the circuit board 140 completely overlaps the second hollow structure 141. Alternatively, in an embodiment, the area of the second hollow structure 141 can be greater than the area of the first hollow structure 1221, and the orthographic projection of the first hollow structure 1221 on the circuit board 140 is completely located in the second hollow structure 141, which is beneficial to reduce the assembly precision requirement. Alternatively, in an embodiment, the area of the first hollow structure 1221 can be greater than the area of the second hollow structure 141, and the orthographic projection of the first hollow structure 1221 on the circuit board 140 completely covers the second hollow structure 141, which is also beneficial to reduce the assembly precision requirement.

[0075] In an embodiment, a partial region of the first heat sink 130 is located in the first hollow structure 1221 and the second hollow structure 141. Therefore, the part of the first heat sink 130 can penetrate the first hollow structure 1221 and the second hollow structure 141 to be in heat-conducting connection with the optical module 300.

[0076] Figure 9 This is a schematic diagram of the connection state of the optical cage assembly 100 and the optical module 300 in an embodiment of this application, as shown below. Figure 9 As shown, in one embodiment, the housing 120 includes a first vent 124, which is located on the side of the first receiving cavity 150 away from the insertion interface 121. Since the insertion interface 121 itself is open, the first receiving cavity 150 forms a first heat dissipation channel between the insertion interface 121 and the first vent 124. With the optical module 300 installed in the first receiving cavity 150, the first vent 124 is located on the side of the optical module 300 facing the top plate 123. Therefore, the first heat dissipation channel is located on the side of the optical module 300 facing the top plate 123. In this solution, heat dissipation can be achieved on the side of the optical module 300 facing the top plate 123, thereby improving the heat dissipation capacity of the optical module 300.

[0077] For specific embodiments, please refer to Figure 9 This design allows the optical module 300 to include a body 330 and a second heat sink 340. The second heat sink 340 is fixedly installed on the side of the optical module 300's body 330 facing the top plate 123 of the optical cage assembly 100. When the optical module 300 is installed between the optical cage assemblies 100, the second heat sink 340 is located within the first heat dissipation duct, which improves the heat dissipation effect of the second heat sink 340. This allows for heat dissipation of the optical module 300 on the side facing the top plate 123, enabling efficient heat dissipation on both sides of the optical module 300 and resulting in better heat dissipation performance.

[0078] Please continue to refer to this. Figure 9In a further embodiment, the shell 120 can further include an additional shell plate 125 located on the side of the bottom plate 122 away from the top plate 123, and the additional shell plate 125 forms a second accommodating cavity 160 with the bottom plate 122, the second accommodating cavity 160 is located adjacent to the first accommodating cavity 150, and the second accommodating cavity 160 and the first accommodating cavity 150 are separated by the bottom plate 122. The second accommodating cavity 160 is used to accommodate the first heat sink 130, that is, the first heat sink 130 is located in the second accommodating cavity 160. The second accommodating cavity 160 includes a second vent 1251 and a third vent 1252, and the second vent 1251 and the third vent 1252 are arranged along the insertion direction X of the optical cage assembly 100. The second accommodating cavity 160 forms a second heat dissipation air duct between the second vent 1251 and the third vent 1252, and the first heat sink 130 is located in the second heat dissipation air duct. When the optical module 300 is installed in the first accommodating cavity 150, the second heat dissipation air duct is located on the side of the bottom plate 122 away from the optical module 300. In this scheme, the second heat dissipation air duct can improve the heat dissipation efficiency of the first heat sink 130, and further improve the heat dissipation effect on the side of the optical module 300 facing the bottom plate 122, so as to improve the heat dissipation capacity of the optical module 300.

[0079] In a specific embodiment, the first heat sink 130 is located in the second heat dissipation air duct to improve the heat dissipation effect of the first heat sink 130. Thus, the optical module 300 can be efficiently cooled on the side facing the bottom plate 122, so that the optical module 300 has a better heat dissipation effect.

[0080] Figure 10 An exploded structural schematic view of the optical cage assembly 100 in an embodiment of the present application is shown in FIGS. 1 and 2. Figure 9 and Figure 10 In an embodiment, the optical cage assembly 100 further includes a connector 110 mounted on the side of the shell 120 away from the insertion port 121. When the optical module 300 is installed in the first accommodating cavity 150 of the optical cage assembly 100, the optical module 300 is electrically connected to the connector 110. The connector 110 includes a connector body 111 and a cable 112, and the connector body 111 and the cable 112 are connected. Specifically, the cable 112 is connected to the side of the connector body 111 away from the insertion port 121, and the cable 112 extends from the shell 120 of the optical cage assembly 100 to the side away from the insertion port 121.

[0081] In the embodiment of the present application, the connector 110 of the optical cage assembly 100 can be a standard connection saddle. For example, the connector 110 can be an octal small form-factor pluggable (OSFP) connector, or an octal small form-factor pluggable X double (OSFP-XD) connector. Although the optical module 300 connected with the OSFP connector or the OSFP-XD connector is provided with the second heat sink 340, the second heat sink 340 can continue to dissipate heat for the optical module 300. However, the optical module 300 connected with the OSFP connector or the OSFP-XD connector has a large signal transmission density, and it is difficult to meet the heat dissipation requirement only by the second heat sink 340. In the embodiment of the present application, the first heat sink 130 is arranged on the optical cage assembly 100, and the first heat sink 130 can dissipate heat for the optical module 300 on the side of the optical module 300 away from the second heat sink 340. Therefore, the optical module 300 can dissipate heat on both sides, which effectively improves the heat dissipation efficiency of the optical module 300 and improves the signal transmission rate of the optical module 300.

Please refer to Figure 10 to 14 In an embodiment, the optical cage assembly 100 further includes a metal partition plate 170, which is mounted on the side of the connector body 111 away from the plug interface 121. The metal partition plate 170 includes a plurality of grooves 171, and one of the grooves 171 accommodates at least one cable 112. In this scheme, the metal partition plate 170 is used to separate the plurality of cables 112. The groove 171 in the metal partition plate 170 has an opening, and the cable 112 close to the middle of the connector can be directly placed into the groove 171 from the opening without passing through the through hole, which is beneficial to simplify the assembly process of the optical cage assembly 100.
