The patent discloses a 2xN type RJ45 socket connector, which comprises an insulating body and a terminal module housed in the insulating body. The terminal module includes a base and a conductive terminal integrally formed with the base, and the conductive terminal comprises Holding and retaining portion in the base, the bent portion extending from the base from the retaining portion, and the elastic contact portion extending rearward and obliquely from the curved portion, but when the RJ11 plug is mistakenly inserted into the RJ45 socket connector, The number of mating terminals of the RJ11 plug is small, and some of the terminals of the RJ45 socket connector are butted against the mating terminals of the RJ11 plug, while the other terminal will be pressed by the insulator of the RJ11 plug, and the part of the terminal pressed by the insulator will be lowered.

Therefore, it is necessary to design a new RJ45 socket connector to solve the above technical problems.

The technical problem to be solved by the present invention is to provide an RJ45 socket connector that prevents the conductive terminals from being lowered.

In order to solve the above technical problem, the technical solution of the present invention is: an RJ45 socket connector, comprising: an insulating body, a conductive terminal held in the insulating body, the insulating body includes a receiving cavity, and the conductive terminal comprises a receiving cavity Elastic connection in the cavity a contact portion, the elastic contact portion extends obliquely rearward in the insertion direction, the elastic contact portion includes a first segment extending obliquely upward, a second segment bent downward and backward from the first segment, and continuing from the second segment a third segment extending obliquely upward, when the RJ45 plug is inserted, the vicinity of the corner of the mating terminal of the RJ45 plug is in electrical contact with the connection of the first segment and the second segment of the elastic contact portion, when the RJ11 plug is incorrect After insertion, the horizontal lower surface of the insulator of the RJ11 plug is adapted to be able to withstand and move forward along the junction of the first and second segments, preventing the RJ11 plug from lodging the resilient contact.

Compared with the prior art, the elastic contact portion of the conductive terminal of the RJ45 socket connector of the present invention is bent into three segments so that the last third segment does not contact the RJ11 plug.

Referring to the first, second and sixth figures, an RJ45 socket connector 100 is interfaced with the RJ45 plug 200. Since the RJ11 plug 300 and the RJ45 plug 200 are similar in appearance, there may be a case where the RJ11 plug 300 is mistakenly inserted into the RJ45 socket connector 100, because the number of mating terminals of the RJ11 plug 300 and the conductive end of the RJ45 socket connector 100 are present. The sub-42 does not match. When the RJ45 socket connector 100 is erroneously inserted, the conductive terminal 42 is pressed by the insulator 310 of the RJ11 plug 300 to cause a fall.

Referring to the third embodiment, the RJ45 socket connector 100 includes a mask housing 20, an insulative housing 30 received in the mask housing 20, a terminal module 40 received in the insulative housing 30, and a bottom portion mounted on the rear of the insulative housing 30. The base 50 and the inner circuit board 60 mounted on the base 50. The insulative housing 30 includes an abutting surface 31 , an abutting portion 32 disposed on the mating surface 31 , and a receiving cavity 33 extending rearward from the mating portion 32 . The receiving cavity 33 is composed of a rear wall 34 of the insulative housing 30 and a bottom wall 35 perpendicular to the rear wall 34. The bottom wall 35 is provided with a recess 350 for receiving the terminal module 40. The terminal module 40 includes an insulator 41 and a conductive terminal 42 integrally formed in the insulator 41. The upper surface of the insulator 41 is provided with a plurality of bumps 410. The two sides of each of the bumps 410 are provided with inclined faces 411 adjacent to each other, so that when the conductive terminals 42 are pressed down, the adjacent conductive terminals 42 are too close. It will be separated along the inclined faces 411 on both sides. The rear wall 34 and the bottom wall 35 of the insulative housing 30 are each provided with a terminal receiving groove 36, and the terminal receiving groove 36 on the rear wall 34 extends in the vertical direction.

Referring to FIGS. 4 to 5 , the conductive terminal 42 includes a holding portion 420 held in the insulator 41 , a curved portion 421 extending forward from the holding portion 420 beyond the insulator 41 , and a rearward direction from the bending portion 421 in the insertion direction. The elastic contact portion 422 extending obliquely upward and the self-holding portion 420 extend rearward beyond the welded portion 423 of the insulator 41. The soldering portion 423 is connected to the inner circuit board 60. The bending portion 421 is received in the terminal receiving groove 36 of the bottom wall 35 of the insulative housing 30. The end of the elastic contact portion 422 is received in the terminal receiving groove 36 of the rear wall 34, and the elastic contact portion 422 is pressed. When elastic deformation occurs, the end of the elastic contact portion 422 moves up and down in the terminal housing groove 36 of the rear wall 34. The elastic contact portion 422 is received in the receiving cavity 33 and includes an obliquely extending upward The first segment 4221, the second segment 4222 bent downward and backward from the first segment 4221 and the third segment 4223 extending obliquely upward from the second segment 4222. The first segment 4221 and the third segment 4223 are substantially parallel to each other. When the RJ45 plug is inserted into the receiving cavity 33 of the RJ45 socket connector 100, and the RJ45 plug 200 is inserted into the rear wall 34 of the insulating body 30, the vicinity of the corner of the mating terminal 201 of the RJ45 plug 200 is electrically contacted with the conductive terminal 42, and The connection of the first section 4221 and the second section 4222 of the elastic contact portion 422 is pressed.

Referring to the sixth figure, when the RJ11 plug 300 is mistakenly inserted into the RJ45 socket connector 100, since the mating terminal of the RJ11 plug 300 does not match the conductive terminal 42 of the RJ45 socket connector 100, the insulator 310 of the RJ11 plug 300 is pressed against the conductive. The terminal 42, when the RJ11 plug 300 is inserted into the rear wall 34 of the insulative housing 30, the horizontal lower surface of the insulator 310 of the RJ11 plug 300 is adapted to be able to withstand the connection of the first segment 4221 and the second segment 4222 of the resilient contact portion 422. Moving forward along the joint and not in contact with the third segment 4223 effectively prevents the incorrect insertion of the RJ11 plug 300 and causes the conductive terminal 42 of the RJ45 receptacle connector 100 to fall.

The above are only the embodiments of the present invention, and are not all or the only embodiments.
