In another embodiment, as shown in fig. 1, the optical module box further includes a fixing cover 600, two ends of the fixing cover 600 are respectively connected to two opposite sides of the optical module box 200 along the first direction, and a middle section of the fixing cover 600 is covered on the heat dissipation member 300 to connect the heat dissipation member 300 to the optical module box 200. So arranged, the heat sink 300 is convenient to mount and dismount on the light module case 200. Further, fixing holes 610 are provided at both sides of the fixing cover 600, and fixing blocks 240 are provided at both sides of the optical module case 200, and when the fixing blocks 240 are fastened in the fixing holes 610, the heat dissipation member 300 can be connected to the optical module case 200.

Next, a process of inserting and extracting the optical module body 100 into the optical module case 200 will be further described with reference to fig. 11 to 14:
the insertion process comprises the following steps: as shown in fig. 11 and 13, the optical module body 100 is inserted into the optical module case 200, and as the optical module body 100 is further inserted, the moving member 410 gradually enters the mating groove 110, and the abutting groove wall 111 of the accommodating groove 230 can abut the abutting surface 411 of the moving member 410, so that the moving member 410 moves in a direction approaching the accommodating groove 230. Then, the moving member 410 enters the accommodating groove 230, and the first limiting structure 700 is present, so that when the optical module body 100 is inserted into the optical module case 200, the moving member 410 can only move along the extending direction of the first limiting groove 710 in the accommodating groove 230. When the moving member 410 moves in the accommodating groove 230 in a direction approaching the abutting groove wall 111, the end, approaching the optical module body 100, of the heat dissipating surface 310 obliquely arranged at the bottom of the heat dissipating member 300 is first contacted with the optical module body 100 and kept relatively stationary; along with the further movement of the moving member 410, the moving member 410 can drive the connecting member 420 to move, and the connecting member 420 drives the heat dissipating member 300 to move downwards, so that the other end of the heat dissipating surface 310 far from the optical module body 100 gradually contacts with the surface of the optical module body 100. Finally, as shown in fig. 12 and 14, the elastic member 430 collides with the groove wall of the accommodating groove 230 and presses, when the optical module body 100 is completely inserted, the optical module body 100 and the optical module case 200 are fixed by the second limiting structure 500, and the elastic member 430 is in a compressed state, and the heat dissipation surface 310 of the heat dissipation member 300 is completely attached to the surface of the optical module body 100.
The pulling-out process comprises the following steps: when the optical module body 100 is pulled out of the optical module box 200, the elastic member 430 resets and provides a force to the moving member 410 away from the accommodating groove 230, the moving member 410 moves away from the abutting groove wall 111, and drives the connecting member 420 to move away from the abutting groove wall 111, and the connecting member 420 moves and drives the heat dissipating member 300 to move upwards. Accordingly, as the optical module body 100 is gradually pulled out, one end of the heat dissipating surface 310, which is close to the elastic member 430, is gradually separated from the surface of the optical module body 100 until the other end of the heat dissipating surface 310 is also separated from the surface of the optical module body 100, so that the heat dissipating surface 310 is completely separated from the surface of the optical module body 100. Finally, the optical module body 100 is completely pulled out, and the whole plugging process is completed.
