3) the connecting portion of the second optical fiber connector 40 enters the connecting groove 106 of the first optical fiber connector 30 mounted in the first adapting box 10, and is completely mated with the connecting portion of the first optical fiber connector 30. The inner box 21 in the second adaptive box 20 is blocked from moving;
4) the outer box 23 in the second adapter box 20 continues to move forward under the pushing force of the daughter board, because the inner box 21 and the outer box 23 in the second adapter box 20 are in floating connection;
5) the hook 102 of the first adapter 10 is inserted between the inner case 21 and the outer case 23 from the front end of the second adapter 20, and is fixed to the slot 213 of the second adapter 20. The first adapter box 10 and the second adapter box 20 are fixed to each other, and the connection process of the optical fiber connection device is completed.
In the aspect of optical fiber connection, the data center chassis of this embodiment is connected more smoothly and more accurately than the prior art, because of the following reasons:
the inner box 21 and the outer box 23 of the first and second adaptive boxes 20 are in floating connection, and are more easily butted with the first adaptive box 10;
the outer box 23 of the second adapting box 20 and the outer box 23 of the second adapting box 20 are provided with elastic strips 231, so that the first adapting box 10 and the second adapting box 20 can float in the width direction when being connected, and the accurate butt joint of the optical fiber connectors is further increased;
thirdly, the first adapter box 10 can float at the upper and lower positions of the first PCB 501, so that the problem of deviation of the upper and lower positions of the first optical fiber connector 30 and the second optical fiber connector 40 caused by machining errors can be solved, and the accurate butt joint of the optical fiber connectors can be further increased;
fourth, the position of the second adapter 20 in the width direction of the second PCB 601 can be floated, and the solution can be further solved based on the elastic strip 231: the accurate mating of the optical fiber connectors can be further increased due to the problem that the positions of the first optical fiber connector 30 and the second optical fiber connector 40 in the width direction are deviated due to the machining error.
Of course, those skilled in the art will understand that the above four technical means may be implemented separately, but need not be implemented in combination.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. that are within the spirit and principle of the present invention should be included in the present invention.
