DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: Figure 1-6 As shown, a liquid-cooled optical module includes an optical module body 10, which includes an outer shell, a PCB board 104 fixedly installed in the shell, and an optical cable connector 105, and a protective member 30 is provided on the PCB board 104 and the optical cable connector 105;

[0031] The protective member 30 includes a cover plate 301 covering the upper end of the PCB board 104, and the cover plate 301 at least completely covers the optical device on the PCB board 104;

[0032] The protective member 30 further includes a sealing member 304 , which is embedded inside the optical cable connector 105 .

[0033] Further, such as Figure 3 as well as Figure 5 As shown, the cover plate 301 covers the area of the PCB board 104 containing the optical device (not shown in the figure). The cover plate 301 should be made of a material that can shield the cooling oil from causing refraction problems to the optical device. For example, the cover plate 301 can be made of a non-transparent material. In order to ensure the reliability of the fixation between the cover plate 301 and the PCB board 104, the cover plate 301 and the PCB board 104 are fixed at the edge with sealant or other airtight connection methods. In addition, as Figure 5As shown, a cavity 3011 is further defined in the cover plate 301. The cavity 3011 is primarily designed to avoid the optical device. The height of the cavity 3011 should be higher than the highest surface of the optical device to prevent the cover plate 301 from pressing on the optical device and causing damage to the optical device.

[0034] For the protection of the optical cable connector 105, the sealing member 304 provided on the inner side of the optical cable connector 105 is further provided. Figure 6 As shown, an air filling cavity 3041 is further provided in the sealing member 304, and air is stored in the air filling cavity 3041. An air filling port 305 is fixedly connected to the upper end surface of the sealing member 304, and the air outlet end of the air filling port 305 is interconnected with the air filling cavity 3041. An active optical cable includes an optical cable head 20, an interface 22 is provided on the inner side of the optical cable head 20, and a connecting core 106 is further provided on the inner side of the optical cable connector 105. The interface 22 is fixedly plugged into the outer side of the connecting core 106. After the optical module body 10 and the optical cable are assembled, the air filling port 305 is inflated so that the air filling cavity 3041 in the sealing member 304 is filled. The sealing member 304 can fill the gap between the optical cable head 20 and the interface 22, thereby preventing cooling oil from entering between the optical cable head 20 and the interface 22, and avoiding problems such as corrosion of the active optical cable.

[0035] Further, such as Figure 5 As shown, the air inlet end of the air filling port 305 is also threadedly connected with a nut 306;

[0036] Further, such as Figure 5 As shown, it is also considered that the protective member 30 can be made into an integrated form. The protective member 30 also includes a connecting strip 302 disposed between the cover plate 301 and the sealing member 304. The connecting strip 302 is a flexible metal strip so that it can bypass the optical cable connector 105 during assembly. The end of the connecting strip 302 away from the cover plate 301 is also fixedly connected to the sleeve connector 303, and the sealing member 304 is fixedly mounted on the sleeve connector 303. In this way, the cover plate 301 and the sealing member 304 can be accurately positioned on the upper end of the PCB board 104 and the inner side of the optical cable connector 105.

[0037] Further, such as Figure 2 As shown, the outer shell includes a lower shell 101 and an upper shell 102 fixedly connected to each other. The lower shell 101 has a cavity corresponding to the PCB board 104 and the optical cable connector 105 for installation; a handle 103 is also provided on one side of the lower shell 101;

[0038] Further, such as Figure 1 As shown, a cable 21 is also connected to one side of the optical cable head 20 .

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
