The frame body 30 has a base portion 31 , wall portions 32 disposed on both sides of the base portion 31 , and a fastening portion 33 disposed on a front end of the electrical connector 10 . A receiving groove 34 is formed between the two wall portions 32 and two sides of the electrical connector body 10 for receiving the aforementioned lever 70 . The two wall portions 32 are respectively provided with a through hole 35 near the middle thereof, and the aforementioned driving lever 70 is inserted into the through hole 35 . The frame body 30 is provided with a sliding groove 36 at the middle position between the base portion 31 and the wall portion 32 , which is matched with the aforementioned blocking piece 50 , and the sliding groove 36 extends from the base portion 31 of the frame body 30 to the wall portion 32 .

Please refer to Figures 1-5, the blocking piece 50 is roughly in the shape of an "S", and the blocking piece 50 is provided with a connecting portion 51 connected to the frame body 30, and the other end is provided with a stop portion 53 which rests on the aforementioned chip module 3, And the pressure receiving portion 55 located between the connecting portion 51 and the blocking portion 53 . The connecting portion 51 is provided with a notch 511 for matching with the slide groove 36 of the aforementioned frame body 30 . The blocking piece 50 can rotate along a first rotation axis parallel to the two opposite wall portions 32 of the aforementioned frame body 30 . When the blocking piece 50 is not squeezed by the driving lever 70, the blocking piece 50 is rotated to the open state, so as to facilitate placement of the chip module 3; when the blocking piece 50 is squeezed by the driving lever 70, the driving lever 70 is pressed on the The pressure receiving portion 55 exerts force on the aforementioned blocking portion 53 , thereby blocking the aforementioned chip module 3 on the aforementioned electrical connector body 10 .
