(b) configuring an elastic curve-shape of the contact end, and a neck, a taper and an engagement in sequence in the section between said contact end and said body portion, and configuring both of the terminals being toward the same direction with an up and down arrangement, so as an unfinished metal part be provided; (c) placing the unfinished metal part on a hole of a plastic-injecting die reversely, wherein a fender tool and a resisting tool ascend from the bottom, deviating said engagement; and a shaping tool descends from the top to keep near to said fender tool; (d) ejecting the plastic to form said insulative housing which includes a tongue extended along a back-to-front direction and a base portion located behind said tongue, and which configures a hollow chamber in the center of its body, hereunder the area between said tongue and said base portion, wherein the chamber is equally divided into several independent slots by a plurality of ribs, wherein a plurality of first terminals is configured on the insulative housing and passes through the slots, said rear portion is held by the base portion of the insulative housing, said contact end and said body portion are exposed out of the base portion, and locate in the slot, a preserved space is formed by the leant neck and said engagement and under said taper, said engagement extends further into the bottom of slots, wherein a plurality of second terminals is configured on the insulative housing, said body portion is held by the base portion and ribs of the insulative housing, one end of second terminal extends out of the base portion, the other end passes through the rib and extends to be disposed above of the tongue, and which configures said ramping portions in the bottom of slots that ascends the ramping portion to the base portion, located between the shaping tool and the fender tool; (e) replacing tools, descending said fender tool and said resisting tool from the bottom, ascending said shaping tool from the top, and returning the engagement and contacting with the ramping portions once again, so as a semi-product be provided; (f) assembling the semi-product with a shell, so the electrical connector is finished thereof. ### Claim 2 (depends on 1) The method for manufacturing an electrical connector as described in claim 1, wherein the step (b), the taper of said contact end is generally in a curve-shape; said neck is configured from said body portion and extends upwardly t said o said taper. ### Claim 3 (depends on 1) The method for manufacturing an electrical connector as described in claim 1, wherein the step (a), said body portion is configuring with a flat and an extension, said flat connects the neck in one end and connects to said extension in the other end. ### Claim 4 (depends on 1) The method for manufacturing an electrical connector as described in claim 1, wherein the step (a), said first terminals configure apertures on the two side terminal onto said engagement. ### Claim 5 (depends on 1) The method for manufacturing an electrical connector as described in claim 1, wherein the step (c)-(e) further comprising: a clamping tool retains said body portion of the second terminal. ### Claim 6 (depends on 1) The method for manufacturing an electrical connector as described in claim 1, wherein the step (c), said shaping tool is installed from a top die; and said fender tool and said resisting tool are installed from a bottom die, the unfinished metal part is placing reversely in the hole which is formed on the surface of said bottom die. ### Claim 7 An electrical connector, comprising: an insulative housing, a plurality of first terminals, a plurality of second terminals and a shell, the insulative housing is engaging with the shell and further includes a tongue extended along a back-to-front direction and a base portion located behind the tongue, the insulative housing configures a hollow chamber in the center of its body, hereunder the area between the tongue and the base portion, the chamber is equally divided into several independent slots by a plurality of ribs, which configures ramping portions in the bottom of slots that ascends the ramping portion to the base portion; and a plurality of first terminals is configured on the insulative housing and passes through the slots, wherein each first terminal has an elastic curve-shape contact end, a rear portion and a body portion connecting two, the rear portion is held by the base portion of the insulative housing; the contact end and the body portion are exposed out of the base portion, and locate in the slot, in the section between the contact end and the body portion, a neck, a taper and an engagement are configured in sequence, a preserved space is formed by the leant neck and engagement and under the taper, the engagement extends further into the bottom of slots and remains contacting with the ramping portions; and A plurality of second terminals is configured on the insulative housing and crosses with the plurality of first terminals in a transverse direction, both of the terminals are toward the same direction with an up and down arrangement, a body portion is held by the base portion and ribs of the insulative housing, One end of second terminal extends out of the base portion; the other end passes through the rib and extends to be disposed above of the tongue. ### Claim 8 (depends on 7) The electrical connector as described in claim 7, wherein the taper of the contact end is generally in a curve-shape; said neck is configured from said body portion and extends upwardly to said taper, the preserved space is formed by the leant neck and said engagement and under said taper. ### Claim 9 (depends on 7) The electrical connector as described in claim 7, wherein said body portion is configuring with a flat and an extension, said flat connects said neck in one end and connects to said extension in the other end, said extension connects to said rear portion ### Claim 10 (depends on 7) The electrical connector as described in claim 7, wherein said first terminals configure apertures on the two side terminal onto said engagement.
