An existing electric connector CN201710037145.2 includes an insulating body 10, a first terminal group 20 and a second terminal group 30. The insulating body 10 includes a main body part 11 and a tongue plate 12 protruding forward from the main body part 11. The first terminal group 20 and the second terminal group 30 each include a contact part 21, 31 at the front end and a soldering leg 22, 32 at the rear end. The contact part 21 of the first terminal group 20 is arranged on the upper surface of the tongue plate 12, and the soldering leg 22 extends backward out of the insulating body 10 and is arranged in a row. The contact part 32 of the second terminal group 30 is arranged on the lower surface of the tongue plate 12, and the soldering leg 32 extends backward out of the insulating body 10 and is also arranged in a row, while being located below the soldering leg 22 of the first terminal group 20. The flexible circuit board 3 includes a first end 81 and a second end 82 opposite to each other. The first end 81 is clamped between the soldering leg 22 of the first terminal group 20, the tail part 32 of the partition plate 40 and the soldering leg 32 of the second terminal group 30. In other embodiments, the flexible circuit board 3 can be replaced by a flexible flat cable.

[0003] In the above structure, the following problems exist:

[0004] The soldering legs 22, 32 extend backward out of the insulating body 10, and the first end 81 is clamped between the soldering leg 22 of the first terminal group 20, the tail part 32 of the partition plate 40 and the soldering leg 32 of the second terminal group 30.

The second metal shell 60 is sleeved on the plastic part 40 from the end of the plastic part 40 away from the insulating body 10.

[0037] As shown in Figure 1 , the insulating body 10 comprises a base 101, a tongue plate 102 extending from one side of the base 101, a first buckling part 103 located on the upper surface of the base 101, and a receiving groove 104 recessed downward from the upper surface of the base 101.

[0038] As shown in Figure 1 and Figure 8 , a plurality of conductive terminals 20 are arranged along the left-right direction, a plurality of conductive terminals 20 are arranged into two rows along the up-down direction, and the center iron sheet 30 is located between the two rows of conductive terminals 20. The conductive terminal 20 comprises a fixed part 201, an interface part 202 and a spring arm 203 connected to the two ends of the fixed part 201 respectively.

[0040] like Figure 7 to Figure 9 As shown, the plastic component 40 includes a rear surface 401, a slot 402 recessed forward from the rear surface 401, multiple terminal slots 403 located on the upper and lower sides of the slot 402, sidewalls 404 located on the left and right sides of the slot 402, and end walls 405 located on the upper and lower sides of the slot 402.

The multiple elastic arms 203 of the conductive terminal 20 are respectively received in the multiple terminal slots 403, with the conductive portion 2031 extending into the slot 402 for elastically contacting the conductive element 200. The latch arm 302 includes a latch portion 3021 that protrudes into the slot 402 and a stop portion 3022 connected to the latch portion 3021. The stop portion 3022 extends out of the slot 402 and abuts the side wall 404.

The end wall 405 protects the horizontal portion 2032 from being struck by the conductive element 200, thereby preventing the elastic arm 203 of the conductive terminal 20 from becoming pinned. The abutment between the first flat surface 4051 of the end wall 405 and the second flat surface 20321 of the horizontal portion 2032 reduces wear during the abutment between the horizontal portion 2032 and the end wall 405, thereby ensuring the conductive transmission performance of the conductive terminal 20.

The seating groove 407 is located behind the receiving groove 104 .

[0041] like Figure 2 to Figure 4As shown, the first metal housing 50 includes a mounting portion 501 that sleeves the insulating body 10, a first limiting portion 502 extending rearward from the mounting portion 501, a second limiting portion 503 extending rearward from the mounting portion 501, two third limiting portions 504 extending upward from the left and right sides of the second limiting portion 503, and a first locking portion 505 located on the second limiting portion 503. The first limiting portion 502 is located above the second limiting portion 503 and passes through the receiving groove 104 and the mounting groove 407. The first limiting portion 502 prevents the insulating body 10 and the plastic component 40 from moving in the left and right directions. The first limiting portion 502 includes a first metal sheet 5021 and a second metal sheet 5022, which lock together. The insulating body 10 and the plastic component 40 are both located between the two third limiting portions 504. The two third limiting portions 504 prevent the insulating body 10 and the plastic component 40 from moving left and right, facilitating the left-right positioning of the insulating body 10 and the plastic component 40 and facilitating the sleeve placement of the plastic component 40 within the second metal housing 60. The protrusion 410 is located below the third limiting portions 504. The first locking portion 505 engages with the second locking portion 408.

[0042] like Figure 4 to Figure 6As shown, the second metal shell 60 includes a sleeving part 260 sleeving the plastic part 40 and a shielding part 602 extending from the sleeving part 260.

The third extending parts 6013 and the fourth extending parts 6014 are fixed to each other, which is beneficial to the stability of the sleeving part 260. The second clamping part 603 is clamped with the first clamping part 103, which can prevent the plastic part 40 from loosening. The first limiting part 502, the second limiting part 503 and the two third limiting parts 504 are located in the sleeving part 260, and the sleeving part 260 stops the displacement of the first limiting part 502, the second limiting part 503 and the two third limiting parts 504. The first metal sheet 5021 and the second metal sheet 5022 are respectively spot-welded with the sleeving part 260, which ensures the stability of the mutual clamping of the first metal sheet 5021 and the second metal sheet 5022. The third limiting part 504 is located between the plastic part 40 and the third extending part 6013, and is used for preventing the third limiting part 504 from being deformed by warping. The two protrusions 410 are located between the two third extending parts 6013, and the third extending parts 6013 limit the displacement of the protrusions 410 in the left-right direction. The shielding part 602 is located behind the first rear surface 4011 and stops the rear displacement of the first rear surface 4011, which further prevents the plastic part 40 from loosening. The shielding part 602 is provided with a through slot 6021, and the through slot 6021 is a continuous frame opening, which can avoid the through slot 6021 of the shielding part 602 being easily warped at the disconnected part, thereby reducing the shielding effect of the shielding part 602. The through slot 6021 is used for the conductive element 200 to pass through in the front-rear direction. The protruding part 409 is accommodated in the through slot 6021, and the shielding part 602 can stop the left-right displacement of the protruding part 409 and the upward-downward displacement of the protruding part 409. In other embodiments, the through slot 6021 is a disconnected frame opening, and the shielding part 602 can stop the left-right displacement of the protruding part 409 or the upward-downward displacement of the protruding part 409.

[0043] In summary, the electric connector 100 has the following advantages:

[0044] (1) The connection between the electric connector 100 and the conductive element 200 is achieved by plug-in connection. The plastic part 40 is provided with a plurality of terminal grooves 403 for accommodating the elastic arms 203 of the conductive terminals 20, thereby avoiding short circuit between the adjacent two elastic arms 203 in a row of conductive terminals 20 and protecting the stability of the contact between the conductive connection part 2031 of the conductive terminal 20 and the conductive element 200. The first metal shell 50 is sleeved on the insulating body 10 from the end of the plastic part 40 away from the insulating body 10. The first clamping part 505 of the first metal shell 50 is clamped with the second clamping part 408 of the plastic part 40, which is conducive to the positioning between the insulating body 10 and the plastic part 40. The second metal shell 60 is sleeved on the plastic part 40 from the end of the plastic part 40 away from the insulating body 10. The second clamping part 603 of the second metal shell 60 is clamped with the first clamping part 103 of the insulating body 10, which is further conducive to the positioning between the insulating body 10 and the plastic part 40. The cooperation of the first metal shell 50 and the second metal shell 60 can shield the electromagnetic wave interference emitted by the conductive terminal 20 to the outside and prevent the electromagnetic wave from the outside from entering the electric connector 100 to interfere with the conductive terminal 20. The second metal shell 60 includes a sleeving part 260 sleeving the plastic part 40 and a shielding part 602 extending from the sleeving part 260. The shielding part 602 is located behind the rear surface 401. The shielding part 602 shields a part of the conductive terminal 20. The shielding part 602 can prevent the electromagnetic wave from the outside from entering the electric connector 100 from the back to the front to interfere with the conductive terminal 20. The cooperation of the sleeving part 260 and the shielding part 602 is conducive to shielding the electromagnetic wave interference emitted by the elastic arm 203 to the outside and the electromagnetic wave interference emitted by the elastic arm 203 from the outside.

[0045] (2) The shielding part 602 is provided with a through groove 6021 which is a continuous frame opening. The through groove 6021 of the shielding part 602 is less likely to warp at the disconnected part, thereby reducing the shielding effect of the shielding part 602. The protruding part 409 is accommodated in the through groove 6021. The shielding part 602 can prevent the left and right displacement of the protruding part 409 and the upward and downward displacement of the protruding part 409.

[0046] (3) The first metal sheet 5021 and the second metal sheet 5022 are clamped with each other and are spot-welded with the sleeving part 260 respectively, thereby ensuring the stability of the clamping between the first metal sheet 5021 and the second metal sheet 5022.

[0047] (4) The horizontal part 2032 extends out of the insertion groove 402. The end wall 405 prevents the horizontal part 2032 from being hit by the conductive element 200, thereby avoiding the kneeling PIN phenomenon of the elastic arm 203 of the conductive terminal 20. The first plane 4051 of the end wall 405 and the second plane 20321 of the horizontal part 2032 abut with each other, thereby reducing the abrasion of the horizontal part 2032 and the end wall 405 during abutting and ensuring the conductive transmission performance of the conductive terminal 20.

[0048] The above detailed description is only for the preferred embodiments of the present application, and does not limit the patent scope of the present application, so that any equivalent technical changes made according to the content of the present application and drawings are included in the patent scope of the present application.
