Figures 1 to 5 show an electrical connector assembly 100 of the present invention, which includes an electrical connector 3 and a chip module 2 assembled on the electrical connector 3, the electrical connector 3 includes an insulating base 1 and a holding Conductive terminals 4 in the insulating base 1 .

Please refer to Figs. 1 to 3, the chip module 2 is roughly in the shape of a cube and has a three-layer structure, that is, the chip module 2 includes an upper layer 21, a lower layer 23 and an intermediate layer between the upper layer 21 and the lower layer 23 twenty two. The length and width of the middle layer 22 are smaller than those of the upper layer 21 and the lower layer 23 , and the middle layer 22 is contracted relative to the upper layer 21 and the lower layer 23 . The three layers of the chip module 2 are provided with notches at four corners thereof, that is, the upper notch 210 , the lower notch 230 and the middle notch 220 . The upper layer 21 is made of metal material and the area of the upper layer 21 is larger than the area of the middle layer 22, so the upper layer 21 has good heat conduction and heat dissipation functions, and the heat generated by the middle layer 22 can be transferred to the upper layer 21 so as to dissipate quickly.

Referring to FIGS. 1 to 5 , the electrical connector 3 includes an insulating base 1 and a conductive terminal 4 held in the insulating base 1 . The insulating base 1 includes a bottom wall 10 , elastic arms 11 and resisting portions 12 extending upward from four corners of the bottom wall 10 . The bottom wall 10 and the elastic arm 11 form a receiving space 15 for receiving the chip module 2 . Opposite two sides of the bottom wall 10 are recessed inwardly to define pick-up slots 101 to facilitate picking and placing of the chip module 2 . The elastic arm 11 includes a main body 111 and a locking portion 110 connected to the main body 111 , located above the main body 111 and protruding toward the receiving space 15 .
