In the heat sink module, an upper heat sink module is accommodated in an upper heat sink bracket. The design of this upper heat sink bracket is for assembly on a guide shield with a single plug-in channel. The inserts on the two side walls of the upper heat sink bracket need to extend downward and backward to the side walls of the guide shield to be inserted into the slot. In addition, the rear end of the lower wall of the upper heat sink bracket has a snap-on piece, which can be snapped into the snap-on groove of the top wall of the guide shield during assembly.

Since the protrusion 741 is protruding outwardly, the flange 742 is spaced from the outer side of the second side plate 252. When the first side plate 242 and the second side plate 252 are overlapped correspondingly, the protrusion 741 passes through the blocking hole 7 21 and its flange 742 extends upward into the recessed portion 720 and abuts against the outer side of the blocking piece 723, so that the blocking piece 723 is between the second side plate 252 and the flange 742.

Furthermore, in this embodiment, the buckle piece 321 of each second buckle component 32 has a buckle groove 322 with an inner top edge 323 and an inner bottom edge 324, and in this embodiment, the inner top edge 323 and the inner bottom edge 324 are staggered in the left-right direction by making the partial plate 325 of the buckle piece 321 defining the inner top edge 323 bend obliquely toward the direction of the insertion channel 11, and its function will be described later.

Referring to FIGS. 6, 8 and 9, the locking structure 4 includes a first locking member 41 disposed on the bottom frame portion 23 of the radiator bracket 2, and a second locking member 42 disposed on the mounting portion 13. The first locking member 41 includes an elastic arm 411, a locking portion 412 disposed on the elastic arm 411, and an unlocking portion 413. The elastic arm 411 is disposed on a local area of the bottom frame portion 23. The groove 40 is formed to form an elastic sheet and is defined. The elastic arm 411 is a cantilever elastic sheet and is located at the rear end of the bottom frame portion 23 of the radiator bracket 2 and extends backward, and can be elastically deformed up and down relative to the bottom frame portion 23. The lock portion 412 is formed by the elastic arm 411 being partially pressed and protruding downward. The unlocking portion 413 is a pull piece extending laterally and obliquely up and down from the elastic arm 411. In this embodiment, the second lock component 42 is a lock hole provided on the top wall 12 and located behind the opening 131 of the mounting portion 13, and is a lock hole penetrating the top wall 12. The inclined pull piece is used to form an insertion space 410 between the top wall 12 of the shielding shell 1 when the buckle portion 412 is buckled in the buckle hole.

When the radiator bracket 2 is assembled on the top wall 12 of the shielding shell 1, the radiator bracket 2 is positioned between the two side portions 132 of the mounting portion 13. Then, the buckle protrusions 311 of the first buckle components 31 of the frame portions 22 on both sides of the radiator bracket 2 are respectively buckled into the buckle grooves 322 of the corresponding second buckle components 32 in the rearward direction. By buckling the first buckle components 31 and the second buckle components 32, the radiator bracket 2 and the shielding shell 1 are positioned in the left-right direction and the up-down direction. Here, the inner top edge 323 and the inner bottom edge 324 of each buckle groove 322 are staggered in the left-right direction and the position abutting against the buckle protrusions 311 is staggered in the left-right direction, so that the buckle stability of the first buckle components 31 and the second buckle components 32 can be improved. In addition, the locking portion 412 of the first locking component 41 is inserted into the locking hole of the second locking component 42 to provide positioning of the heat sink bracket 2 and the shielding shell 1 in the front-rear direction.

It is worth noting that since the unlocking portion 413 of the first locking component 41 is an inclined lever and forms an insertion space 410 with the top wall 12 of the shielding shell 1, when the first locking component 41 and the second locking component 42 need to be unlocked, the unlocking portion 413 can be pushed upward with a finger, or a tool can be inserted into the insertion space 410 to pry upward, so that the locking portion 412 can be disengaged from the second locking component 42 upward, and then, the radiator bracket 2 can be moved so that the buckle protrusion 311 of the first buckle component 31 is withdrawn from the buckle groove 322 of the second buckle component 32, and the radiator bracket 2 can be separated from the shielding shell 1.

In addition to the aforementioned structure, in this embodiment, the side frame 22 of the heat sink bracket 2 is further provided with a plurality of downwardly directed guide protrusions 243, and each side portion 132 of the mounting portion 13 is provided with an elongated guide hole 133, providing each guide protrusion 243 with a length in the front-rear direction greater than the guide protrusion 243. By providing the guide protrusion 243 and the elongated guide hole 133, the heat sink bracket 2 is provided with a guide for assembly to the shielding housing 1.

Therefore, the present invention is provided with the first locking part 41 and the second locking part 42, and the elastic arm 411 is an independently movable plate. When releasing the locking relationship between the first locking part 41 and the second locking part 42, it is not limited by the direction of the first snap-on part 31 and the second snap-on part 32. Compared with the prior art, it is indeed easier to disassemble and assemble. In addition, the structure and matching method of the first snap-on part 31 and the second snap-on part 32 are also applicable to the structural form of the shielding shell 1 with multiple insertion channels 11.

4 , 6 , 11 and 12 , the heat sink 6 of this embodiment includes a base 62 , a pressure member 63 , a pressure spring 64 and two contact springs 65 in addition to a plurality of heat sink fins 61 interlocked with each other, and a heat conductive pad 621 is disposed at the bottom of the base 62 . The heat sink fin 61 is disposed on the base 62, and the base 62 extends into the insertion channel 11 through the opening 253 of the bottom plate 251 of the lower bracket 25 of the heat sink bracket 2 and the opening 131 of the mounting portion 13 of the top wall 12 of the shielding shell 1 so as to contact the inserted connector 5. The pressing member 63 has a front end 631 facing forward and a rear end 632 facing downward, and the two ends are pivotally arranged on the two side frame portions 22 of the heat sink bracket 2. The rear end 632 extends through the opening 253 of the bottom plate 251 of the lower bracket 25 of the heat sink bracket 2 and the top wall 12 of the shielding shell 1. The opening 131 of the mounting portion 13 extends into the insertion channel 11, and the pressure spring 64 abuts between the base 62 and the front end 631 of the pressure member 63. The contact spring 65 is arranged below the base 62 and located in the insertion channel 11. When the connector 5 is inserted into the insertion channel 11 and pushes against the rear end 632 of the pressure member 63, the pressure member 63 pivots downward at the front end 631 and presses the pressure spring 64 downward, and then the pressure spring 65 contacts the connector 5 through the base 62, thereby achieving close contact between the heat sink 6 and the connector 5.
