Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Optical modules are important components in the field of optical communications, including plugs and optical interfaces. The plug is also called an electrical interface and is used for being matched and plugged with a socket on a circuit board in the communication equipment, and the optical interface is used for connecting optical fibers. The optical module can convert an electrical signal input from the plug into an optical signal and output the optical signal from the optical interface, or convert an optical signal input from the optical interface into an electrical signal and output the electrical signal from the plug, or convert an electrical signal input from the plug into an optical signal and output the optical signal from the optical interface, and simultaneously convert an optical signal input from the optical interface into an electrical signal and output the electrical signal from the plug. The orientation relationship between the plug and the optical interface in the optical module can be various. In some embodiments, as shown in fig. 1, the plug 011 and the optical interface 012 are respectively disposed at two opposite ends of the optical module 01. In other embodiments, as shown in fig. 2, plug 011 and optical interface 012 are disposed at the same end of optical module 01.

Fig. 3 is a schematic structural diagram of a communication device according to some embodiments of the present application, and fig. 4 is an exploded view of the communication device shown in fig. 3. As shown in fig. 3-4, the communication device includes a panel 02, a circuit board 03, a socket 04, and a light cage 05. The panel 02 is provided with a jack 021. The circuit board 03 is disposed 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 insertion opening 041 of the socket 04 faces the insertion opening 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 light cage 05 is surrounded by a slot 051, and the slot 051 is communicated with the jack 021 and the jack 041.

As shown in fig. 3 to 4, the communication device further includes an optical module 01, and the optical module 01 may be the optical module shown in fig. 1, the optical module shown in fig. 2, or an optical module having another configuration. And is not particularly limited herein. Fig. 3 to 4 are described only by taking the optical module 01 as an example of the optical module shown in fig. 1. The plug 011 of the optical module 01 passes through the jack 021 and the slot 051 to be plugged in the socket 04, and the optical cage 05 is used for guiding the plug 011 of the optical module 01 to be plugged in the socket 04 quickly.

In order to timely conduct and dissipate the heat of the optical module 01, as shown in fig. 3-4, heat dissipation holes 052 may be formed in the optical cage 05, and the heat sink 06 may be covered at the heat dissipation holes 052. When the optical module 01 is inserted into the optical cage 05, the optical module 01 contacts with the heat sink 06, so that heat is conducted out and dissipated in time through the heat sink 06. However, the size of the heat sink 06 is limited by the size of the light receiving cage 05, so that the volume of the heat sink 06 cannot be made large, the contact area between the optical module 01 and the heat sink 06 is limited, the effective heat dissipation area of the optical module 01 is small, and the heat dissipation efficiency is low. Meanwhile, because of the influence of the surface flatness of the light receiving module 01 and the heat sink 06, the optical module 01 and the heat sink 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 (namely the sum of the discrete point contact areas) between the optical module 01 and the heat sink 06 is small, and the air thermal resistance is large, so that the friction force of the heat sink 06 on the optical module 01 when the optical module 01 is inserted into the optical cage 05 is small, the optical module 01 can be conveniently inserted, and the heat dissipation efficiency of the optical module 01 is further reduced.

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 an electrical signal and convert the electrical signal into an optical signal for output, or the communication device can receive an optical signal and convert the optical signal into an electrical signal for processing.

The heat dissipation housing 211 is fittingly sleeved outside the optical module 21, and passes through the jack 111 on the panel 11 in fig. 6 along with the optical module 21 to be plugged into the communication device 1. The front end of the heat dissipation case body 211 along the insertion direction (i.e., the direction X) of the heat dissipation case body is provided with a first opening 211 a. The optical module 22 includes a plug 221, and the plug 221 of the optical module 22 protrudes from the heat dissipation case body 211 through the first opening 211 a. The plug 221 of the optical module 2 is plugged into the receptacle 12 in fig. 6, thereby obtaining an assembly diagram as shown in fig. 5.

In the embodiment of the present application, the heat dissipation housing body 211 plays a role of dissipating heat of the optical module 22, and the heat dissipation housing body 211 is sleeved outside the optical module 22, so that a coverage area between the heat dissipation housing body 211 and the optical module 22 can be increased. Moreover, the size and structure of the heat dissipation housing body 211 may be designed so that the heat dissipation housing body 211 is tightly wrapped outside the optical module 22, so as to increase the actual contact area in the unit coverage area between the heat dissipation housing body 211 and the optical module 22, reduce the thermal resistance between the heat dissipation housing body 211 and the optical module 22, and improve the heat dissipation efficiency of the optical module 22.

Thus, when the cover plate 2112 is removed from the base 2111, the first side portion 213b and the second side portion 213c of the buckle 213 are snapped so that the bent portion between the first side portion 213b and the supporting portion 213a and the bent portion between the second side portion 213c and the supporting portion 213a are elastically deformed, and the engagement structure between the first side portion 213b and the first side plate 2111b and the engagement structure between the second side portion 213c and the second side plate 2111c are separated, so that the buckle 213 can be removed to remove the cover plate 2112. When the cover plate 2112 is installed on the base 2111, the cover plate 2112 may be pre-covered at an opening at one end of the groove 2113 away from the bottom plate 2111a, and then the fastener 213 is fastened to the cover plate 2112 from the side of the cover plate 2112 away from the base 2111, so that the first side portion 213b of the fastener 213 is attached to the outer surface of the first side plate 2111 b. The second side portion 213c is attached to the outer surface of the second side plate 2111c, the first side portion 213b is connected to the first side plate 2111b in a snap-fit manner, and the second side portion 213c is connected to the second side plate 2111c in a snap-fit manner, so that the cover plate 2112 is mounted.

The buckle 213 can be made into a sheet structure, and after being fastened to the cover plate 2112 and the base 2111, the buckle is tightly attached to the surfaces of the cover plate 2112 and the base 2111, so that the size of the surface protruding out of the cover plate 211 and the base 2111 is small, the occupied space is small, and the heat dissipation housing body 211 can be conveniently inserted into the communication device after being sleeved outside the optical module 22 and passing through the jack on the panel of the communication device along with the optical module 22.

In the above embodiment, the clamping structure between the first side portion 213b and the first side plate 2111b may be: a clamping groove 215 is formed in the first side portion 213b, a buckle 214 is arranged on the outer surface of the first side plate 2111b, and the clamping groove 215 is clamped on the buckle 214.

To facilitate the removal or installation of the optical module into or out of the notch 2113, in some embodiments, as shown in fig. 9, the heat dissipation housing body 211 further includes: guide ribs 218. Guide ribs 218 are provided on an inner surface of at least one of the first side plate 2111b and the second side plate 2111c, the guide ribs 218 extending in a direction perpendicular to the bottom plate 2111 a. Thus, when the optical module is taken out or put into the recess 2113, the optical module can be guided by the guide rib 218, so that the efficiency of taking out or mounting the optical module is improved.

In the above embodiment, the number of the guide ribs 218 may be one or more, and is not particularly limited herein.

Thus, when the optical module 22 is sleeved in the heat dissipation housing body 211 of the heat dissipation housing 21, the optical module 22 may press the heat conductive material layer to compress or flow the heat conductive material layer to conform to the surface of the optical module 22. Therefore, the inner surface of the heat dissipation shell body 211 is effectively attached to the outer surface of the optical module 22, and the heat exchange area and the heat exchange efficiency between the heat dissipation shell 21 and the optical module 22 are increased.

In some embodiments, as shown in fig. 8, the heat sink housing body 211 is made of a conductive shielding material including, but not limited to, aluminum-based metals and copper. In this way, the heat dissipation case body 211 can rapidly dissipate heat of the optical module, and also serves as a shield case of the optical module to electromagnetically shield the optical module. On this basis, the heat dissipation case 21 further includes: a conductive structure 216. The conductive structure 216 is disposed on the outer surface of the heat dissipation housing body 211 and is in conductive contact with the heat dissipation housing body 211, and the conductive structure 216 abuts against the inner wall of the panel at the insertion hole 111 of the communication device shown in fig. 6. Thereby, the conductive member 216 provides electrical conduction between the heat dissipation case body 211 and the panel 11, and thus, the common ground connection between the heat dissipation case body 211 and the panel 11 can be achieved.

In the above embodiments, the conductive structure 216 may be a conductive elastic sheet or a flexible conductive shielding material layer (such as a conductive cloth), which is not limited in this respect. For example, the conductive structure 216 shown in fig. 8 is a conductive spring.

In some embodiments, as shown in fig. 10, optical interface 222 and plug 221 are located at opposite ends of optical module 22 along its plugging direction. On the basis, as shown in fig. 7, the rear end of the heat dissipation housing body 211 along the self-plugging direction is provided with a second opening 211b, the optical interface 222 is located in the heat dissipation housing body 211, and the optical interface 222 is opposite to the second opening 211 b. In this way, the optical interface 222 is evacuated through the second opening 211b, so that the optical interface 222 can externally connect an optical fiber.

The fixing structure 217 only realizes the fixation between the heat dissipation housing body 211 and the panel, and the optical module is only plugged into a socket in the communication device and sleeved in the heat dissipation housing body 211, and under the action of external force, the optical module is easily dropped from the socket and is slid out from the second opening 211b of the heat dissipation housing body 211. To avoid this, in some embodiments, as shown in fig. 9, the heat dissipation case 21 further includes: a stop structure 219. The stopping structure 219 is used to prevent the optical module from sliding out of the heat dissipation housing body 211 through the second opening 211b, so as to ensure the stability of the plug-in connection between the optical module with the heat dissipation housing and the socket.
