The insulating body 10 includes opposite front and rear end faces 11 and 12, a top face 13 located between the front and rear end faces, and a longitudinal card slot 14 penetrating forwardly, and the contact portions 21 of the terminals 20 extend into the card slot 14. In combination Figure 8 , the insulating body 10 includes a fixing slot 15 located above the card slot 14 and penetrating the front end face 11, and the fixing slot 15 does not penetrate the rear end face 12 of the insulating body 10.

[0025] The heat dissipation module 200 includes a fixing plate 201 extending from one end thereof and a guide plate 202 extending over the fixing plate 201 and extending a longer distance. The fixing plate 201 of the heat dissipation module 200 is obliquely inserted into the fixing groove 15 and rotated to a horizontal state and finally accommodated and fixed in the fixing groove 15. The guide plate 202 of the heat dissipation module 200 cooperates with the top surface 13 to play a guiding role. The assembly of the heat dissipation module 200 and the card edge connector 100 does not need to rely on tools and is simple to operate. Since the fixing groove 15 is only provided with a forward opening, the insulating body has better structural strength and is not easy to be damaged due to assembly or disassembly of the heat dissipation module 200. The weight of the heat dissipation module 200 is supported by the insulating body 10, avoiding deformation of the metal shell 30 caused by long-time support of the heat dissipation module 200. In the first embodiment, the card edge connector is provided with one fixing groove 15, and the heat dissipation module 200 is correspondingly provided with one fixing plate 201.
