本發明電連接器100用於焊接至一電路板(未圖示)以電性連接一晶片模組200，如第一圖至第七圖所示，所述電連接器100包括具有複數個端子 孔10的絕緣本體1以及複數個一一對應地收容於所述端子孔10內的導電端子2。所述絕緣本體1具有相對的上表面11與下表面12，所述端子孔10貫穿所述上、下表面11、12。所述導電端子2包括用於與所述晶片模組200接觸的對接臂21以及用於焊接至所述電路板且呈上下延伸設置的焊接臂22，所述對接臂21包括固持於所述端子孔10內的第一主體部210以及自所述第一主體部210向上彎折延伸出所述上表面11的彈性臂211，所述對接臂21與焊接臂22彼此獨立且間隔設置，當所述晶片模組200下壓時，所述彈性臂211會向下移動進而抵壓所述焊接臂22，以形成電性導通。所述焊接臂22包括上下延伸且固持於所述端子孔10內的第二主體部220、自所述第二主體部220向上傾斜延伸的彎曲部221以及自所述第二主體部220向下延伸至所述絕緣本體1下表面12的植球部222，所述彎曲部221位於彈性臂211的下方，且彈性臂211向下移動而抵接在所述彎曲部221，所述植球部222通過一錫球3焊接至所述電路板。從第六圖與第七圖可以看出，在本實施例中，所述彎曲部221突伸出所述上表面11，所述植球部222突伸出所述下表面12。 The electrical connector 100 of the present invention is used for soldering to a circuit board (not shown) to electrically connect a chip module 200, as shown in the first to seventh figures, the electrical connector 100 includes a plurality of terminals The insulating body 1 of the hole 10 and a plurality of conductive terminals 2 are accommodated in the terminal hole 10 in a one-to-one correspondence. The insulating body 1 has an upper surface 11 and a lower surface 12 opposite to each other, and the terminal hole 10 penetrates the upper and lower surfaces 11 , 12 . The conductive terminal 2 includes a docking arm 21 for contacting the chip module 200 and a welding arm 22 extending up and down for welding to the circuit board. The first body part 210 in the hole 10 and the elastic arm 211 bent upward from the first body part 210 and extending out of the upper surface 11, the butt arm 21 and the welding arm 22 are independent and spaced apart from each other.

It can be seen from the sixth and seventh figures that in this embodiment, the curved portion 221 protrudes from the upper surface 11 , and the ball-planting portion 222 protrudes from the lower surface 12 .

如第三圖至第七圖所示，所述彈性臂211包括自所述第一主體部210的上端朝所述焊接臂22的方向彎折延伸的彎折部2111、自所述彎折部2111向上傾斜延伸的傾斜部2112以及自所述傾斜部2112彎折延伸的弧形接觸部2113。所述晶片模組200面向所述電連接器100的一面設有用於與所述接觸部2113連接的接觸片201，由於所述彈性臂211呈上述彎折的長臂狀延伸，因此所述彈性臂211具有較好的彈性，當所述對接臂21與所述晶片模組200接觸時，所述彈性臂211能夠與所述接觸片201保持良好的電性接觸。 As shown in the third figure to the seventh figure, the elastic arm 211 includes a bent portion 2111 bent and extended from the upper end of the first main body portion 210 toward the direction of the welding arm 22 , from the bent portion 2111 is an inclined portion 2112 extending upward and an arc-shaped contact portion 2113 bent and extending from the inclined portion 2112 . The surface of the chip module 200 facing the electrical connector 100 is provided with a contact piece 201 for connecting with the contact portion 2113. Since the elastic arm 211 extends in the shape of the above-mentioned bent long arm, the elastic The arm 211 has better elasticity, and when the docking arm 21 is in contact with the wafer module 200 , the elastic arm 211 can maintain good electrical contact with the contact piece 201 .

When the elastic arm 211 presses against the bending portion 221, the bending portion 2111 of the elastic arm 211 is further bent due to the pressure, and the inclined portion 2112 of the elastic arm 211 will follow the bending portion 221 slides to provide a supporting force, thereby preventing excessive deformation of the bent portion 2111 due to pressure, and avoiding The conductive terminal 2 loses its elasticity, which can prolong the service life of the conductive terminal 2 . In this embodiment, the upper surface 11 of the insulating body 1 has an upward protruding boss 110 , the elastic arm 211 protrudes upward from the boss 110 , and the curved portion 221 is located on the upper surface 11 between the boss 110 so that the electrical connector 100 is fully in contact with the chip module 200 to achieve stable electrical conduction. After the chip module 200 presses down on the electrical connector 100, the elastic arm 211 is deformed by force and electrically contacts the soldering arm 22 until the chip module 200 touches the The boss 110 of the insulating body 1 stops the deformation, and the setting of the boss 110 provides enough space for the deformation of the elastic arm 211, but the space for the space is in the rebound of the elastic arm 211. Within the range, it is beneficial to further avoid excessive deformation of the elastic arm 211 due to being pressed.

重點參閱第七圖，所述電連接器100的導電端子2在對接時其彈性臂211彈性抵接於豎直設置的所述焊接臂22的上端，焊接臂22下端的植球部222直接焊接至所述電路板，即所述彈性臂211抵壓所述彎曲部221以在所述晶片模組200與所述電路板之間形成大致豎直延伸的導電路徑。相比於只能通過彎曲的長臂狀彈性臂傳輸電流的傳統彈性端子而言，本發明的導電端子2能夠在一定程度上縮短所述晶片模組200與電路板之間的電流路徑，改善導電端子2的高頻特性，提升導電端子2的傳輸速率，提高電連接器100的高頻性能。 Focusing on the seventh figure, the elastic arm 211 of the conductive terminal 2 of the electrical connector 100 elastically abuts against the upper end of the vertically arranged welding arm 22 when it is docked, and the ball planting part 222 at the lower end of the welding arm 22 is directly welded. To the circuit board, that is, the elastic arm 211 presses against the bent portion 221 to form a substantially vertically extending conductive path between the chip module 200 and the circuit board. Compared with the traditional elastic terminal that can only transmit current through the curved long-arm elastic arm, the conductive terminal 2 of the present invention can shorten the current path between the chip module 200 and the circuit board to a certain extent, improving The high-frequency characteristic of the conductive terminal 2 increases the transmission rate of the conductive terminal 2 and improves the high-frequency performance of the electrical connector 100 .
