Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1 to FIG. 8 , the present invention is mounted on a printed circuit board 200 for the positive and negative insertion of a mating connector (not shown), including an insulating body 1 and being held by The conductive terminal 2 and the metal piece 3 in the insulative housing 1 are sleeved on the outside of the insulative housing 1 to form the metal inner casing 4 of the receiving space 10 and the metal outer casing 5 mounted outside the metal inner casing 4. The metal inner casing 4 and the metal outer casing 5 may be collectively referred to as a metal casing (not numbered).

Referring to the fifth and sixth figures, the insulative housing 1 includes a first insulative housing 11 and a second insulative housing 12 that are injection molded twice. The metal piece 3 is held by the first insulative housing 11 . The first insulative housing 11 is provided with a first terminal slot 111 on the upper surface and a second terminal slot 112 on the lower surface. The conductive terminal 2 includes an upper signal terminal 21 mounted in the first terminal slot 111 and a signal terminal 22 mounted on the lower side of the second terminal slot 112. The upper row of signal terminals 21 and the lower row of signal terminals 22 are mounted on the first insulative housing 11 and are retained by the second insulative housing 12 . The upper row of signal terminals 21 includes a first contact portion 211 located in the first terminal slot 111 and a first solder portion 212 bent downward from the first contact portion 211 to extend outside the second insulative housing 12 . The lower row of signal terminals 22 includes a second contact portion 221 and a second solder portion 222 extending from the second contact portion 221 in a straight line outside the second insulative housing 12 . The metal piece 3 is in the form of a sheet, and includes a flat plate portion 31 held in the first insulative housing 11 and a pair of welding angles 32 extending downward from the side of the flat plate portion 31. Therefore, the flat plate portion 31 of the metal piece 3 is located between the first contact portion 211 of the upper row of signal terminals 21 and the second contact portion 221 of the lower row of signal terminals 22. The signal line terminal 21 and the lower row signal terminal 22 are disposed diagonally with respect to the center point of the electrical connector 100, and the first contact portion 211 and the lower row signal terminal 22 of the upper row of signal terminals 21 are disposed. The second contact portion 221 is disposed to face up and down. The first welded portion 212 and the second welded portion 222 are located in the same plane and are disposed in two rows in the front and rear. The welding angle 32 is located outside the first welding portion 212 and the second welding portion 222 and the three are coplanar so as to be welded together to the printed circuit board 200.
