The connector 7 for the light guide has a plurality of accommodating holes 71, and two ends of each accommodating hole 71 respectively accommodate corresponding The light entrance end 611 of the light guide tube 61 of the light guide member 6 and the corresponding light-emitting element, to ensure that the light emitted by these light-emitting elements can enter the light entrance end 611 of the light guide pipe 61 of the corresponding light guide member 6 respectively. . In addition, the rear connecting column 64 of each light guide member 6 is formed with a card slot 641 located on the inner side, and the light guide member connecting member 7 also has a card slot 641 that is fastened to the corresponding light guide member 6 from the inside to the outside. The two hooks 72 and the positioning posts 73 for passing through the circuit board, so that the light guide member is fixed between the two light guide members 6 and the circuit board by the connecting member 7 .

Referring to FIG. 8 to FIG. 10 , the difference between the second embodiment of the connector assembly 100 of the present invention and the first embodiment is that the top wall 11 of the cover body 1 and the base plate 41 of the heat sink 4 are arranged between the There are a plurality of support springs 8 . Further, in the second embodiment, the top wall 11 of the cover body 1 has the supporting springs 8 that are located beside the window 162 and are integrally formed in the shape of elastic sheets, but it should be noted that in other implementations In this aspect, the support springs 8 may be integrally formed in the heat sink 4, or the support springs 8 may be independent components.

When the radiator 4 is in the inactive position, the support spring 8 lifts the radiator 4 upwards and separates the base plate 41 of the radiator 4 from the top wall 11 of the cover 1 , and makes the radiator 4 The thermal coupling surface 411a does not enter the insertion space 16 of the cover body 1. At this time, the main spring action portion 44 of the heat sink 4 does not contact the main spring portion 53 of the pressing member 5, and the main spring portion 53 of the pressing member 5 The spring portion 53 does not act on the main spring action portion 44 of the heat sink 4 . When the pluggable module 3 (see FIG. 1 ) is inserted into the insertion space 16 of the cover 1 and during the stroke before pushing the pushed protrusion 413 , the main spring action portion 44 of the heat sink 4 is still not in contact The main spring portion 53 of the pressing member 5 and the main spring portion 53 of the pressing member 5 do not act on the main spring acting portion 44 of the radiator 4 , therefore, the thermal coupling surface 411 a of the radiator 4 is still at this time. Plugs that do not enter the cover 1 The space 16 is in contact with the pluggable module 3 . Finally, when the pluggable module 3 pushes the pushed protrusion 413 of the heat sink 4 and reaches the stroke of mating with the socket connector 2 (see FIG. 1 ), the heat sink 4 moves backward from the inactive position To the acting position, when the radiator 4 is at the acting position, the main spring acting portion 44 of the radiator 4 is in contact with the main spring portion 53 of the pressing member 5, and the main spring portion 53 of the pressing member 5 acts on the main spring acting surface 441 of the main spring acting part 44 of the heat sink 4 to provide a downward force to press the heat sink 4 down so that the thermal coupling surface 411a of the heat sink 4 enters the housing through the window 162 1, and make the thermal interface material 411b on the thermal coupling surface 411a of the heat sink 4 contact the upper surface of the pluggable module 3 with a positive force. That is, before the pluggable module 3 pushes the pushed protrusion 413 of the heat sink 4 to move the heat sink 4 to the working position, the thermal coupling surface 411a of the heat sink 4 It does not contact the surface of the pluggable module 3 , thereby further preventing the wear problem of the thermal coupling surface 411 a of the heat sink 4 , or the thermal coupling surface 411 a of the heat sink 4 is disposed. The problem that the thermal interface material 411b is scratched is described. Generally speaking, in the second embodiment, the heat sink 4 moves backward and downward from the non-active position to the active position during the process of inserting the pluggable module 3 .

In addition, when the pluggable module 3 is withdrawn from the insertion space 16 of the cover 1, the force of the main spring portion 53 of the pressing member 5 and the frictional force of the pluggable module 3 will cause the The radiator 4 moves forward, and the support springs 8 will move the radiator 4 upward to move the radiator 4 from the active position to the inactive position.
