The electrical connector 100 includes an insulative housing 1, and a conductive terminal 2 and a nut 3 disposed on the insulative housing 1. The housing 1 has a slot 10 for receiving one end of the electronic module 2. The conductive terminal 2 includes a contact portion 21 protruding into the slot 10 and a pin 22 extending out of the lower portion of the insulative housing 1. The nut 3 is fixed on the insulating body 1 and located above the slot 10. The electrical connector 100 is further provided with a pair of positioning posts 4 and a bolt 5 engaged with the nut 3. Two positioning columns 4 are respectively positioned at two sides of the nut 3. Thus, one end of the heat dissipation plate 200 is positioned between the pair of positioning posts 4 and fixed above the card slot 10 by a bolt 5 engaging with the nut 3. The positioning column 4 quickly positions the heat dissipation plate 200 to ensure that the heat dissipation plate is not obliquely installed, and the heat dissipation plate is stably and fixedly matched through the bolt 5 and the nut 3, so that the heat dissipation plate is reliably, conveniently and quickly installed.

Referring to fig. 3 and 5, the electrical connector 100 includes a metal housing 6. The metal shell 6 includes a top wall 61, a rear wall 62 bent downward from a rear edge of the top wall 61, and side walls 63 bent downward from both ends of the top wall 61. Fig. 6 clearly shows that a gap 601 is left between the rear wall 62 and the rear end face of the insulating body 1. The rear wall 62 is provided with a spring 621 for holding the nut 3 forward and a fixing wall 622 bent from both sides thereof. The two fixed walls 622 are located between the two side walls 63, i.e., each located inside the adjacent side wall 63. The two sides of the insulator 1 are provided with fixing slots 12 engaged with the fixing walls 622, and the fixing slots 12 extend through the insulator 1 rearward and upward. The metal shell 6 further includes a front wall 64 bent downward from the front edge of the top wall 61 and attached to the front end surface of the insulating body 1, and the front wall 64 extends downward to above the slot 10.

Referring to fig. 3, the top wall 61 defines a first through hole 611 and a second through hole 612, the first through hole 611 being sized to match the size of the bolt 5 for the bolt 5 to pass through. The positioning post 4 integrally extends from the insulating body 1 and protrudes upward and is formed by penetrating through the second through hole 612. The rear end of the positioning column 4 is an arc surface for guiding the heat dissipation plate 200. In order to ensure that the heat dissipation plate 200 cannot be installed obliquely, the opposing surfaces of the two positioning posts 4 are rectangular surfaces parallel to each other.

Referring to fig. 5, the sidewall of the insulating housing 1 is provided with an ear-fastening portion 13 and a limiting groove 14 above the ear-fastening portion 13. The bottom edges of the side walls 63 of the metal shell 6 are caught to the ear clip portions 13 to prevent the side walls 63 from turning up or tilting. The side wall 63 is provided with an inwardly bent stopper 631. The position-limiting piece 631 abuts against the position-limiting groove 14 to prevent the metal shell 6 from loosening in the vertical direction. Two fixing posts 15 with different sizes and profiles are disposed on two sides of the bottom of the housing 1 to ensure the correct installation direction of the electrical connector 100.

Referring to fig. 4 and 6, the insulating housing 1 is provided with a mounting hole 11 penetrating backward and upward, and the nut 3 is fixed in the mounting hole 11. The inner wall surface of the mounting hole 11 is provided with ribs 110 extending horizontally in the front-rear direction, and the ribs 110 are fixed to the nut 3 by interference. The rib 110 is provided at its rear end face with an inclined guide face 111, and the nut 3 is guided by the guide face 111 to be fixed into the mounting hole 11 from the rear to the front. Similarly, the connection between the mounting hole 11 and the rear end surface of the insulating body 1 is provided as a guide slope extending obliquely to the guide surface 111 of the rib 110. The bottom of the mounting hole 11 is provided with a step portion 112 with an arc-shaped inner edge, the nut 3 is fixed on the top surface of the step portion 112 and keeps a certain gap with the bottom surface of the mounting hole 11, and the bolt 5 is prevented from directly abutting against the bottom surface of the mounting hole 11 after being screwed out of the nut 3 downwards.
