In this embodiment, each extension portion 104 is respectively provided with two through holes 1040 at two ends thereof. It is well known in the industry that for the insulating body of the electrical connector, the sidewall is not necessary to achieve electrical contact with the chip module, so the extension portion 104 can directly extend outward from the edge of the base 100 . Two positioning portions 1041 extend from each extension portion 104 .

The bottom of the extension portion 104 is actually the bottom of the insulating housing 10 . When the bottom of the extension portion 104 is not flush with the bottom surface 1000 of the base 100 , the bottom surface is just an uneven plane. The bottom of each extension 104 is respectively provided with a reinforcing piece 18. In this embodiment, the reinforcing piece 18 is roughly in the shape of a sheet, and its material can be metal or other hard materials, and a notch is provided in the middle. , can save materials and reduce costs. Two holes 180 and two pillars 181 are disposed on the reinforcement member 18 , and the pillars 181 are hollow.

The pressing member 14 is provided with a plurality of positioning holes 140 . When the chip module 8 is placed in the receiving cavity of the insulating body 10 , the pressing member 14 will be placed above the chip module 8 . The positioning holes 140 correspond to the aforementioned through holes 1040 .

During assembly, several positioning columns 16 pass through the above-mentioned positioning holes 140; the column body 181 on the reinforcing member 18 passes through the through hole 1040 and cooperates with the positioning column 16, and the holes 180 on the reinforcing member 18 pass through the interference fit method such as socket pressure, and The positioning portion 1401 on the extension portion 104 is combined, so that the reinforcing member 18 is positioned on the bottom surface of the insulating body 10 . The insulating body 10 can be fixed to the circuit board 9 by solder ball welding.

Since the bottom surface 1000 of the insulating body 10 is provided with reinforcements 12, the insulating body 10 is not easily deformed and can ensure a good electrical connection with the chip module 8; and the electrical connector assembly 1 of the present utility model, when the insulating body 10 is mounted on When the circuit board 9 is used, the purpose of strengthening the insulating body 10 can be achieved without providing a backboard on the back of the circuit board 9 , thereby saving the installation space on the back of the circuit board 9 .
