Abstract: The present application relates to DDR connectors, particularly to a new DDR socket connector. The DDR socket connector comprises two fastening posts, an insert and a plugging groove. Each of the fastening posts are made of plastic and located at two sides of the groove. The insert is embedded in one of the two fastening posts and made of metal, and the insert includes a main body and two side parts. The main body is located in the middle portion of the insert, and the side parts are located at two sides of the main body. Compared with the prior art, the beneficial effects of the present application lie in: the plastic connecting part is inserted with a metal insert to overcome such deficiencies as plastic getting weak when being heated and thus eliminate the adverse impact of high temperature on the product.
