Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Figure 1-7, a DDR5 memory insert connector to prevent internal stress in the illustration, including a plastic socket body 1 and a terminal fixing part 2, the plastic socket body 1 has an installation cavity 3 inside, so The terminal fixing part 2 is installed in the installation cavity 3, and the terminal fixing part 2 is inserted into the installation cavity 3 to realize assembly.

The terminal fixing part 2 is composed of a metal terminal 4, a terminal fixing plate 5 and a block 6. There are multiple metal terminals 4, and the plurality of metal terminals 4 are equidistantly distributed on the terminal fixing plate 5. The terminal fixing plate 5 are provided with two, and the two terminal fixing plates 5 are respectively fixed to the two ends of the tails of the multiple metal terminals 4, and there are multiple clamping blocks 6, and the multiple clamping blocks 6 are equidistant and symmetrically distributed and fixed on the two terminals. On the outside of the fixing plate 5, the metal terminals 4 and the terminal fixing plate 5 are installed in the installation cavity 3, and a plurality of metal terminals 4 are fixed by the terminal fixing plate 5, which is convenient for insertion.
