中國專利CN201320378153.0揭露了一種電連接器，其包括絕緣本體、固持於絕緣本體的第一端子組、第二端子組、屏蔽件及設置於絕緣本體外的金屬殼體，所述絕緣本體包括基部及向前延伸的舌板，所述舌板具有相對設置的第一表面與第二表面，第一端子組暴露於所述第一表面，第二端子組暴露於所述第一表面，屏蔽件設置於舌板且位於第一表面與第二表面之間，所述第一端子組包括接地端子，所述接地端子設有朝向所述屏蔽件凸設並接觸該屏蔽件的接觸部。The Chinese patent CN201320378153.0 discloses an electrical connector comprising an insulative housing, a first terminal set held by the insulative housing, a second terminal set, a shielding member and a metal housing disposed outside the insulating body, the insulative housing comprising a base and a forwardly extending tongue, the tongue having opposite first and second surfaces, the first terminal set being exposed to the first surface, the second terminal set being exposed to the first surface, shielding The piece is disposed on the tongue plate and located between the first surface and the second surface, and the first terminal group includes a grounding terminal, and the grounding terminal is provided with a contact portion protruding toward the shielding member and contacting the shielding member.
CN201320378153.0所揭露的這種現有電連接器的第一端子組的焊接部是採用表面貼焊的形式，而第二端子組的焊接部是採用穿孔直插的形式，這種電連接器的端子採用兩種不同焊接形式的焊接部，導致電連接器後部的 體積增大，在電路板上也需要佔用更大的焊接空間，此外使用兩種不同焊接形式的焊接部在進行焊接操作時也需要採用兩種不同類型的焊接設備，導致製程變得更為複雜。並且隨著電連接器的微型化以及電路板的薄型化，在電路板上為第二端子組對應開設穿孔式的焊盤將變得更為困難。另一方面，這種現有連接器在進行高頻高速資料傳輸時，對接腔內的電磁輻射容易向後穿過絕緣本體影響導電端子的焊接部造成串訊。因此現有的電連接器有待於進一步改善。The welding portion of the first terminal set of the prior art electrical connector disclosed in CN201320378153.0 is in the form of surface soldering, and the soldering portion of the second terminal group is in the form of a through-hole plug, the electrical connector The terminal uses two different welding forms of the weld, resulting in the rear of the electrical connector The increase in volume also requires a larger welding space on the board.

Specifically, the main body of the beam 54 is embedded in the reinforcing rib 155 of the main body portion 15, and the two side wing portions 57 are respectively embedded on the two extending side portions 152 of the main body portion 15, so that the structural strength of the main body portion 15 can be enhanced. .
另外，該板體51上形成有多個通孔58。較佳地 ，這些通孔58是圓形的並且沿前後延伸的中軸對稱地排布。該橫樑54與連接部53的交界處也形成有兩個通孔59。這些通孔58、59可以增加第三絕緣件13與接地金屬片5之間的結合強度。Further, a plurality of through holes 58 are formed in the plate body 51. Preferably These through holes 58 are circular and are arranged symmetrically along the central axis extending forward and backward. Two through holes 59 are also formed at the boundary between the beam 54 and the connecting portion 53. These through holes 58, 59 can increase the bonding strength between the third insulating member 13 and the grounding metal piece 5.
參見圖8和圖9，這組第一導電端子21及第一絕緣件11結合成一第一模組7。這組第二導電端子22及第二絕緣件12結合成一第二模組8。該接地金屬片5及第三絕緣件13結合成一第三模組9。其中，該第一模組7是從下往上地疊置在該第三模組9上，從而使該第一導電端子21的對接部211對應***收容在該舌板部16的第一端子收容槽161內；該第二模組8是從上往下地疊置在該第三模組9上，從而使該第二導電端子22的對接部221對應***收容在該舌板部16的第二端子收容槽162內。Referring to FIG. 8 and FIG. 9, the first conductive terminal 21 and the first insulating member 11 are combined into a first module 7. The second conductive terminal 22 and the second insulating member 12 are combined into a second module 8. The grounding metal piece 5 and the third insulating member 13 are combined into a third module 9. The first module 7 is stacked on the third module 9 from bottom to top, so that the abutting portion 211 of the first conductive terminal 21 is correspondingly inserted into the first terminal of the tongue portion 16 . The second module 8 is stacked on the third module 9 from top to bottom, so that the butting portion 221 of the second conductive terminal 22 is correspondingly inserted into the tongue plate portion 16 The two terminals are received in the receiving groove 162.
本新型的電連接器的裝配過程大致包括：衝壓彎折成型導電端子2、外屏蔽殼體3、金屬殼體元件41以及接地金屬片5；然後採用***成型的製造工藝，製得第一模組7、第二模組8以及第三模組9；接著將第一模組7從下往上地插置到第三模組7的收容空間153下部，然後將第二模組8從上往下地插置到第三模組7的收容空間153上部，直至第二絕緣件12的底面與第一絕緣件11的頂面相頂抵，使得該第一模組7設置在該第三模組9上並且該第一模組7和第二模組8將該第三模組9緊密地夾持在其中；接著，將兩個金屬殼體元件41對應裝設到絕緣本體1上；最後，從前往後地將外屏蔽殼體3套到絕緣本體1上 。The assembly process of the electrical connector of the present invention generally comprises: stamping and bending forming the conductive terminal 2, the outer shield shell 3, the metal shell member 41 and the grounding metal sheet 5; and then adopting the manufacturing process of insert molding to obtain the first mold a group 7, a second module 8 and a third module 9; then inserting the first module 7 from the bottom to the bottom of the receiving space 153 of the third module 7, and then moving the second module 8 from above Inserting the upper portion of the receiving space 153 of the third module 7 downward until the bottom surface of the second insulating member 12 abuts against the top surface of the first insulating member 11 , so that the first module 7 is disposed in the third module 9 and the first module 7 and the second module 8 tightly clamp the third module 9 therein; then, the two metal housing elements 41 are correspondingly mounted on the insulative housing 1; finally, The outer shield shell 3 is placed on the insulative body 1 from the rear to the rear. .
與現有技術相比，本新型的電連接器10通過使兩組導電端子21、22的焊接部212、222表面貼裝地焊接到電路板20上，從而有利於縮小電連接器10的體積及減少對電路板20的佔用，還可以簡化焊接工序，另一方面，本新型使這兩組導電端子21、22的焊接部212、222從電連接器10的後方來看呈現為交錯排布，有利於焊接完成後從後方檢查各個焊接部212、222的焊接情況，從而可以減少焊接不良；並且，通過內屏蔽殼體4來與外屏蔽殼體3相配合，可以防止電磁輻射後泄影響導電端子21、22的焊接部212、222，達成增強屏蔽效果的目的。Compared with the prior art, the electrical connector 10 of the present invention facilitates the reduction of the volume of the electrical connector 10 by surface-mounting the soldering portions 212, 222 of the two sets of conductive terminals 21, 22 to the circuit board 20. The reduction of the occupation of the circuit board 20 can also simplify the soldering process. On the other hand, the present invention makes the soldering portions 212, 222 of the two sets of conductive terminals 21, 22 appear staggered from the rear of the electrical connector 10. It is advantageous to check the welding condition of each welding portion 212, 222 from the rear after the welding is completed, so that the welding failure can be reduced; and the inner shielding shell 4 is matched with the outer shielding shell 3, thereby preventing the electromagnetic radiation from leaking and affecting the conduction. The welded portions 212 and 222 of the terminals 21 and 22 achieve the purpose of enhancing the shielding effect.
