[0031] In this embodiment, a heat dissipation component is provided between the optical fiber connecting plug 1 and the docking plug 2 for transferring and dissipating the heat of the core 4 .
[0032] It should be noted that the heat dissipation assembly includes a heat conductive cover 5 installed between the optical fiber connection plug 1 and the inner wall of the heat insulating cover 3 and located outside the core 4 , and a plurality of heat dissipation fins 6 are installed outside the heat conductive cover 5 .

[0034] In this embodiment, a ventilation structure is provided between the optical fiber connector 1 and the heat dissipation assembly to ventilate and dissipate the heat.
[0035] It should be noted that the ventilation structure includes a number of through holes 7 opened on the heat conductive cover 5, an air inlet groove 10 opened on the left side of the optical fiber connector 1, and a number of through holes 9 opened in the optical fiber connector 1 and connected to the air inlet groove 10.
[0036] The second through hole 9 is connected to the space between the heat insulation cover 3 and the heat conduction cover 5 , and the second through hole 9 is located between two adjacent heat dissipation fins 6 .
