Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of these features.

The optical module is an important component in the field of optical communications. The optical module includes a plug and an optical interface. The plug, also called the electrical interface, is used for mating and plugging with the socket on the circuit board in the communication device, and the optical interface is used for connecting the optical fiber. The optical module can convert the electrical signal input by the plug into an optical signal and output by the optical interface, or convert the optical signal input by the optical interface into an electrical signal and output by the plug, or convert the electrical signal input by the plug into an optical signal by the optical interface Output, and at the same time convert the optical signal input by the optical interface into an electrical signal and output it by the plug. There can be multiple azimuth relationships between the plug and the optical interface in the optical module. In some embodiments, as shown in FIG. 1, the plug 011 and the optical interface 012 are respectively disposed at opposite ends of the optical module 01. In other embodiments, as shown in FIG. 2, the plug 011 and the optical interface 012 are arranged at the same end of the optical module 01.

FIG. 3 is a schematic structural diagram of a communication device provided by some embodiments of the application, and FIG. 4 is an exploded view of the communication device shown in FIG. 3. As shown in Figures 3-4, the communication device includes a panel 02, a circuit board 03, a socket 04 and an optical cage 05. A jack 021 is provided on the panel 02. The circuit board 03 is arranged on one side of the panel 02 and fixed to the panel 02. The socket 04 is disposed on the circuit board 03, and the socket 041 of the socket 04 faces the socket 021. The optical cage 05 is connected to the circuit board 03, and the optical cage 05 is located between the socket 04 and the jack 021. The optical cage 05 encloses a slot 051, and the slot 051 is connected to the jack 021 and the jack 041.

As shown in Figures 3 to 4, the communication device further includes an optical module 01. The optical module 01 may be the optical module shown in FIG. 1, or the optical module shown in FIG. 2, or may be an optical module with other structures. Module. There is no specific limitation here. FIGS. 3 to 4 only take the optical module 01 as the optical module shown in FIG. 1 as an example for description. The plug 011 of the optical module 01 passes through the jack 021 and the slot 051 to be inserted into the socket 04, and the optical cage 05 is used to guide the plug 011 of the optical module 01 to be quickly inserted into the socket 04.

In order to conduct and dissipate the heat of the optical module 01 in time, as shown in Figs. 3 to 4, a heat dissipation hole 052 may be provided on the optical cage 05, and the heat sink 06 may be covered at the heat dissipation hole 052. When the optical module 01 is inserted into the optical cage 05, the optical module 01 is in contact with the radiator 06, and thus the heat is conducted and dissipated in time through the radiator 06. However, the size of the radiator 06 is limited by the size of the light cage 05, resulting in that the volume of the radiator 06 cannot be made larger, the contact area between the optical module 01 and the radiator 06 is limited, and the effective heat dissipation area of the optical module 01 is small , The heat dissipation efficiency is low. At the same time, due to the influence of the surface flatness of the light module 01 and the radiator 06, the optical module 01 and the radiator 06 are actually in discrete point contact. In order to reduce the resistance when the optical module 01 is inserted into the optical cage 05, The effective area (that is, the sum of the contact areas of discrete points) between the optical module 01 and the radiator 06 is small, and the air thermal resistance is relatively large, so that the radiator 06 is correct when the optical module 01 is inserted into the optical cage 05. The friction of the optical module 01 is small, which facilitates the insertion of the optical module 01, which further reduces the heat dissipation efficiency of the optical module 01.

In order to improve the heat dissipation efficiency of the optical module, some embodiments of the present application provide a communication device. The communication device can generate electrical signals and convert the electrical signals into optical signals for output, or the communication device can receive optical signals and convert the optical signals into electrical signals for processing.

The optical module 22 includes a plug 221, and the plug 221 of the optical module 22 extends out of the heat dissipation shell body 211 through the first opening 211a. The plug 221 of the optical module 2 is inserted into the socket 12 in FIG. 6 to obtain the assembly diagram shown in FIG. 5.

Since in the embodiment of the present application, the heat dissipation shell body 211 has a heat dissipation effect on the optical module 22, and the heat dissipation shell body 211 is sleeved outside the optical module 22, the coverage area between the heat dissipation shell body 211 and the optical module 22 can be increased. . Moreover, the size and structure of the heat dissipation shell body 211 can be designed so that the heat dissipation shell body 211 is tightly wrapped outside the optical module 22 to increase the actual contact area per unit coverage area between the heat dissipation shell body 211 and the optical module 22, and reduce The thermal resistance between the heat dissipation shell body 211 and the optical module 22 improves the heat dissipation efficiency of the optical module 22.
