1. An electrical connector, comprising:
an insulating housing of which a top face is concaved downward to define a plurality of terminal grooves, the terminal grooves being alternately arranged into two rows along two longitudinal sides of the insulating housing, each terminal groove extending transversely to have the outer end thereof penetrate through a corresponding side face of the insulating housing, the inner ends of the two rows of terminal grooves being alternate with one another along a substantial longitudinal middle of the insulating housing; and a plurality of electrical terminals of which each is curved from a long sheet metal, the electrical terminal having a contact portion, a soldering tail and an elastic portion connected between the contact portion and the soldering tail, the electrical terminals being firstly assembled downward to locate the elastic portions in the terminal grooves respectively and then pushed transversely inward until the elastic portions resist against inner end walls of the corresponding terminal grooves, the soldering tails projecting downward beyond a bottom face of the insulating housing through the terminal grooves and the contact portions elastically projecting upward over the corresponding terminal grooves; wherein the elastic portion of the electrical terminal is of lying-U shape, a lower arm of the elastic portion further extends oppositely to the lower arm to form a strengthening portion extending beyond a free end of an upper arm of the elastic portion, a middle of a free end of the strengthening portion is bent downward and then extends levelly to form the soldering tail, the free end of the upper arm of the elastic portion slantwise extends upward and then is bent downward to form the contact portion located over the strengthening portion and the soldering tail, the strengthening portion is received in the terminal groove and against a bottom sidewall of the terminal groove; wherein two sides of the free end of the strengthening portion of the electrical terminal extend oppositely to the strengthening portion and are further broadened outward to form a pair of fastening flanks, two face-to-face inner sidewalls of the terminal groove are concaved oppositely outward to form a pair of fastening slots which extend transversely outward to penetrate through the side face of the insulating housing and are adjacent to the bottom sidewall of the terminal groove, the electrical terminal is pushed transversely inward to fasten the fastening flanks in the fastening slots. |
