In one embodiment, as shown in fig. 8, the connection element 420 includes a first connection portion 421, a second connection portion 422, and a third connection portion 423 connected in sequence, wherein an end of the first connection portion 421 away from the second connection portion 422 forms a first end of the connection element 420, and an end of the third connection portion 423 away from the second connection portion 422 forms a second end of the connection element 420; the heat sink 300 rotates around the axis of the first connection portion 421, the moving element 410 rotates around the axis of the third connection portion 423, and the axes of the first connection portion 421 and the third connection portion 423 are parallel to each other and cross the axis of the second connection portion 422. The second connection portion 422 of the connector 420 is rotatably connected to the heat sink 300 by the first connection portion 421, and is rotatably connected to the mover 410 by the third connection portion 423. With such an arrangement, the structure of the connector 420 can be simplified while the connector 420 is rotatably connected to the heat sink 300 and the moving element 410, respectively.
In another embodiment, as shown in fig. 1, the optical module case further includes a fixing cover 600, two ends of the fixing cover 600 are respectively connected to two opposite sides of the optical module case 200 along the first direction, and a middle section of the fixing cover 600 covers the heat sink 300 to connect the heat sink 300 to the optical module case 200. So configured, the heat sink 300 is easily attached to and detached from the optical module case 200. Further, fixing holes 610 are formed in both sides of the fixing cover 600, and fixing blocks 240 are formed in both sides of the optical module case 200, so that the heat sink 300 can be coupled to the optical module case 200 when the fixing blocks 240 are fastened in the fixing holes 610. Further, the heat sink 300 is provided with a positioning groove 340, the middle section of the fixing cover 600 is covered in the positioning groove 340, and the positioning groove 340 is convenient for positioning and mounting the heat sink 300.
Next, with reference to fig. 11 to 14, the process of inserting and removing the optical module body 100 into and from the optical module case 200 will be further described:
and (3) an insertion process: as shown in fig. 11 and 13, the optical module body 100 has been inserted into the optical module case 200, the moving piece 410 gradually enters into the fitting groove 110 as the optical module body 100 is further inserted, and the abutting groove wall 111 of the accommodating groove 230 can abut against the abutting surface 411 of the moving piece 410, so that the moving piece 410 moves toward the direction close to the accommodating groove 230. Then, the moving element 410 enters the receiving groove 230, and the first position-limiting structure 700 exists, so that when the optical module body 100 is inserted into the optical module case 200, the moving element 410 can only move in the receiving groove 230 along the extending direction of the first position-limiting groove 710. When the moving element 410 moves in the receiving groove 230 toward the direction close to the abutting groove wall 111, the end of the heat dissipation surface 310, which is obliquely disposed at the bottom of the heat dissipation member 300, close to the optical module body 100 first contacts the optical module body 100 and remains relatively still; with the further movement of the moving element 410, the moving element 410 can drive the connecting element 420 to move, and the connecting element 420 drives the heat sink 300 to move downward, so that the other end far away from the heat dissipation surface 310 of 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 element 430 collides with and presses the groove wall of the receiving groove 230, after 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 element 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.
And (3) pulling out: when the optical module body 100 is pulled out of the optical module case 200, the elastic element 430 is reset and provides an acting force far away from the receiving groove 230 to the moving element 410, the moving element 410 moves in a direction far away from the abutting groove wall 111, and drives the connecting element 420 to move in a direction far away from the abutting groove wall 111, and the connecting element 420 also drives the heat sink 300 to move upward while moving. Therefore, as the optical module body 100 is gradually pulled out, the end of the heat dissipation surface 310 close to the elastic member 430 gradually separates from the surface of the optical module body 100 until the other end of the heat dissipation surface 310 also separates from the surface of the optical module body 100, so that the heat dissipation surface 310 completely separates 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.
