[New content] The purpose of this creation is to provide an I/O connector in which the terminal can be in close contact with an external PCB board in view of the above-mentioned deficiencies. In order to achieve the above objectives, the I/O connector of the present invention includes a housing, a 5 M323731 insulative housing, and a terminal. The outer casing has a top plate, a bottom plate and a side wall, and the top plate, the bottom plate and the side wall enclose a receiving space. The insulating body is inserted into the accommodating space. A plurality of terminal channels are opened on the insulative housing, and a plurality of terminals are inserted in the corresponding terminal channels. The terminal has a retaining portion, a bent portion formed by bending a side edge of the retaining portion-end, a resilient arm formed by a downward extending end of the bent portion, and two engaging portions extending downward from an end of the elastic arm, wherein A snap joint is bent from the end of the elastic arm to the side, and then bent backward and then bent downward, and the other snap portion is bent from the end of the elastic arm to the other side and then reversely bent. Then, it is bent down and extended, and the two snap portions protrude out of the bottom plate of the outer casing. When the 1/0 connector of the creation is assembled on the external PCB board, the terminal is elastically biased against the external PCB board in the direction opposite to the third direction, thereby ensuring the mutual contact and conduction of the telecommunication transmission solids, and thus the card joint and the outer portion. When the PCB board is smashed and the two boards of the terminal are open, a momentary power failure occurs. [Embodiment] For " sheep, and field. The technical content, structural features, and efficacy of the book are as follows. f = = 0 - Figure, the creation of the 1 / 〇 connector 1 includes a peripheral made of plastic material 1 维, dimension to a number of terminals 3G.

Two longitudinally extending positioning blocks 28 respectively embedded in the corresponding positioning grooves 134 are respectively protruded from the two side faces 23 of the insulative housing 20. Referring to the second, fifth and sixth figures, the terminal 30 is divided into a first terminal 31 and a second terminal 32. The first terminal 31 has a holding 4311 in an "L" shape. The side of one end of the holding portion 311 is bent downward to form a bent portion 312. The bow portion 312 extends downwardly to form two elastic arms 313 in the form of strips. The ends of the two elastic arms 313 respectively extend with a latching portion 314, wherein the latching portion ^4 is folded from the end of the corresponding -elastic arm 313 to the left and then to the right, and then folded down, that is, the latching portion 314 is formed by folding the end of the elastic arm 313 to the side 4 and then reversing the 'folding and then bending downwards; the other engaging portion is called from the end of the corresponding other elastic arm 313 to the right and then to the left f After being folded, the buckle portion 314 is formed by folding from the end of the other elastic arm 313 to the other (four) and then bending backward and then extending downward. The level of the holding portion 311 of the terminal π is inserted into the terminal passage 24, and the vertical portion thereof is locked in the terminal positioning path 26. The elastic arm 313 and the engaging portion 314 of the terminal 3〇 are at the lower portion of the insulating body 2G? Out. The second terminal % is similar in structure to the first terminal _ in that the dry portion of the holding portion 321 of the second terminal 32 is slightly shorter than the level portion of the holding portion 3U of the first terminal 31. - The side edges of the ends are folded down to form a bent portion of milk. The bent portion 322 extends downwardly into two strip-shaped elastic arm milks. The ends of the two elastic arms respectively have a catching portion 324.
