Embodiment 1

[0038] like figure 1 , figure 2 As shown, a waterproof structure that allows an SFP optical module to be used in a humid environment includes: a housing 1 and a button 3 arranged on the housing 1;

[0039] The housing 1 includes an optical module accommodating cavity 11 and a connection hole 12 . The optical module 2 is placed in the optical module accommodating cavity 11 , and the optical module connection line 24 passes through the connection hole 12 . The position of 3 corresponds to the position of the buckle 21 of the optical module 2, which is used to press down the buckle 21. The plug end 22 of the optical module 2 is inserted from the opening of the optical module accommodation cavity 11 The opening is provided with a mounting portion 13, and a sealing structure 5 is provided between the mounting portion 13 and the connecting body.

[0040] The invention discloses a waterproof structure that allows the SFP optical module to be used in a humid environment, does not c...

Embodiment 2

[0057] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that an optical module accommodating cavity 11 is provided in the housing, and a plurality of optical modules 2 are arranged in the optical module accommodating cavity 11. The button 3 and the card A crimping plate 4 is arranged between the buckles 21 , and the crimping plate 4 abuts each of the buckles 21 .

[0058] In this embodiment, two buttons 3 are provided, the crimping plate is connected to the bottom of the button 3, and the two buttons are pressed down at the same time to ensure the overall downward movement of the crimping part 4, so that each buckle is opened at the same time, which is convenient for multiple When the optical modules are used at the same time, they must be plugged and unplugged together.

[0059] like Figure 8 As shown, the mounting portion 13 in this embodiment includes elastic claws 17 disposed at both ends of the housing 1, and the elastic claws 17 are ...

Embodiment 3

[0063] like Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the mounting portion 13 includes a crimping portion 18 and an elastic member 19 disposed at both ends of the housing 1, the connecting body is provided with a slot 20, and the The elastic member 19 presses the crimping portion 18 on the connecting body, and both ends of the elastic member 19 are inserted into the slot 20;

[0064] The sealing structure 5 includes a sealing groove 51 and a sealing ring arranged in the sealing groove 51 .

[0065] The elastic member in this embodiment is a spring piece, the two ends of the spring piece have plug-in parts parallel to the connection body, and the middle part of the spring piece is concave toward the crimping part 18 . When in use, the optical module is inserted into the connection body, and the shell The body 1 is attached to the connecting body, and then the two ends of the spring sheet are pinched toward the middle, and the two plug-...

Abstract

The invention provides a waterproof structure capable of enabling an SFP (Small Form-factor Pluggable) optical module to be used in a humid environment. The waterproof structure comprises a shell and a button arranged on the shell, the shell comprises an optical module containing cavity and a connecting line hole, the optical module is arranged in the optical module containing cavity, an optical module connecting line penetrates through the connecting line hole, the position of the button corresponds to the position of the buckle of the optical module and is used for pressing the buckle downwards, the inserting end of the optical module extends out of an opening of the optical module containing cavity, and a mounting part is arranged at the opening and used for mounting the optical module. And a sealing structure is arranged between the mounting part and the connecting main body. According to the waterproof structure capable of enabling the SFP optical module to be used in the humid environment, the structure and the using method of the SFP optical module are not changed, the waterproof structure can be conveniently installed outside the optical module, the SFP optical module is isolated in the humid environment, the optical module can be normally used in the humid environment, the optical module does not need to be installed in equipment, and the waterproof structure is convenient to use. The equipment size is not increased, and maintenance and repair are convenient.

Description

technical field [0001] The invention relates to the application field of optical modules, in particular to a waterproof structure that allows an SFP optical module to be used in a humid environment. Background technique [0002] SFP is the abbreviation of SMALL FORM PLUGGABLE (small pluggable). The working principle and structure of SFP determine that SFP is not suitable for use in humid environments, which limits the application scenarios of SFP optical film blocks. [0003] In the prior art, a device using an optical module in a humid environment needs to install both the optical module and the optical fiber cable inside the device, and make a waterproof structure on the optical fiber cable. However, this will cause disadvantages such as large size of the equipment, difficult to plug and unplug the optical fiber, and inconvenient maintenance. SUMMARY OF THE INVENTION [0004] The present invention provides a waterproof structure that allows the SFP optical module to be...
