[Technical Field]

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector for high-frequency signal transmission. [Background Technology]

[0002] Chinese utility model patent CN202222548961.9 discloses an electrical connector assembly, wherein the mating connector includes a plastic base and multiple terminal assemblies fixed in the plastic base. The terminal assembly has a shielding shell, a pair of signal terminals and an insulator. The signal terminals are fixed to the insulator. The shielding shell surrounds the pair of signal terminals and the insulator. The shielding shell also has a clearance space formed through it along the thickness direction.

[0003] Each pair of signal terminals in the aforementioned electrical connector requires a corresponding shielding shell, meaning that each terminal assembly needs to be manufactured separately, making the manufacturing process quite complex. In addition, the assembly situation of each terminal assembly also needs to be considered during assembly, resulting in low assembly efficiency.

[0004] Therefore, it is necessary to design an electrical connector to overcome the above problems. [Utility Model Content]

[0005] The purpose of this invention is to provide an electrical connector in which a conductive shield and multiple conductive main bodies form multiple receiving spaces, an insulating component and signal terminal pairs are received in the receiving spaces, and multiple insulating components, multiple signal terminal pairs, multiple conductive components and conductive shield are integrally injection molded, thereby enhancing the shielding effect, saving manufacturing costs and improving assembly efficiency.

The extension portion extends forward beyond the insulating body. The shielding body is fixedly connected to a first shielding member. The first shielding member bends forward and extends to have a blocking portion. The blocking portion is located above the extension portion and overlaps with the connecting arm in the vertical direction.

[0012] Furthermore, there are multiple shielding parts, each shielding part downwards to shield a corresponding connecting arm, and there is a fixing groove between two adjacent shielding parts, with the conductive strip located in the fixing groove.

[0013] Furthermore, it includes a first shielding member located on the front side of the signal body portion and a second shielding member located on the rear side of the signal body portion.

Detailed Implementation Methods

[0031] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] The electrical connector of this invention defines the left-right direction as the X-axis, with the leftward direction as the positive X-axis direction; the front-back direction as the Y-axis, with the forward direction as the positive Y-axis direction; the up-down direction as the Z-axis, with the upward direction as the positive Z-axis direction; and the horizontal direction as perpendicular to the up-down direction. When the related structures are arranged in multiple rows in the front-back direction, they are defined sequentially from front to back as the first row, second row, third row, and fourth row.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an electrical connector that connects downward to a mating element, including a housing 1, a signal terminal 2, an insulating component 3, a conductive component 4, a conductive shielding component 42, a shielding component 6, a conductive strip 7, a grounding component 8, and a cable assembly 9. In this embodiment, the mating element is a circuit board.

[0034] The housing 1 includes a front wall 11, a rear wall 12, three fixing strips 14 located between the front wall 11 and the rear wall 12, and two opposing side walls 13. The two side walls 13 connect the front wall 11, the rear wall 12 and the three fixing strips 14. Receiving grooves 15 are provided between the fixing strips 14 and the front wall 11, between two adjacent fixing strips 14, and between the fixing strips 14 and the rear wall 12. The upper surface of the fixing strips 14 extends upward beyond the upper surface of the front wall 11 and the upper surface of the side walls 13, and the upper surface of the rear wall 12 extends upward beyond the upper surface of the front wall 11 and the upper surface of the side walls 13.

[0035] The signal terminals 2 are multiple and housed in the receiving slot 15. Two adjacent signal terminals 2 form a signal terminal pair 20. The multiple signal terminal pairs 20 are arranged in rows along the left and right direction and in four rows along the front and back direction. Specifically, every six signal terminal pairs 20 are arranged in a row along the left and right direction, and every four signal terminal pairs 20 are arranged in a column along the front and back direction. Of course, in other embodiments, multiple signal terminal pairs 20 can also be arranged in rows along the front and back direction and in multiple rows along the left and right direction.

[0036] like Figure 4 and Figure 5 As shown, the signal terminal 2 includes a signal body 22, a signal wiring portion 21 extending backward and upward from the signal body 22, and a signal spring arm 23 extending downward from the signal body 22. The signal spring arm 23 includes a first signal spring arm 231, a connecting arm 232, and a second signal spring arm 233. The first signal spring arm 231 extends forward from the body 22, the connecting arm 232 connects the first signal spring arm 231 and the second signal spring arm 233, and the second signal spring arm 233 extends backward from the connecting arm 232. The second signal spring arm 233 is provided with a signal contact portion 2331 that abuts against the circuit board.

[0037] There are multiple insulating elements 3, and each insulating element 3 fixes a signal terminal pair 20. Of course, in other embodiments, one insulating element 3 can fix multiple signal terminal pairs 20. The insulating element 3 includes an insulating body 31, two partition plates 32 extending upward from the insulating body 31, and two extensions 33 extending downward from the insulating body 31. The extensions 33 extend forward beyond the insulating body 31.

[0038] The signal body 22 is fixed to the insulating body 31. The signal spring arm 23 extends downward beyond the insulating body 31 and is located between the two extensions 33. The connecting arm 232 extends forward beyond the insulating body 31. The signal wiring part 21 is located between the two partition plates 32 and exposes the insulating member 3 upward. Specifically, the signal wiring part 21 includes an upper surface 211, a lower surface 212, and two side surfaces 213 connecting the upper surface 211 and the lower surface 212. The upper surface 211 exposes the insulating member 3 upward. The side surfaces 213 are fixed to the insulating member 3. The insulating member 3 is provided with a groove 311. The lower surface 212 is at least partially exposed in the groove 311, thereby allowing the lower surface to contact more air, changing the dielectric constant around the signal wiring part 21, thereby adjusting the impedance at the signal wiring part 21 and improving signal integrity.

[0039] Along the left-right direction, a conductive element 4 without a hole is provided between two adjacent signal terminal pairs 20. The conductive element 4 includes a conductive main body 41, a bent part 43, and a conductive shielding part 42. The conductive main body 41 is located between two adjacent signal main bodies 22. Both the signal main body 22 and the conductive main body 41 are plate-shaped. The plate surface of the signal main body 22 is perpendicular to the plate surface of the conductive main body 41. The bent part 43 includes a first bent part 431 and a second bent part 432. The first bent part 431 bends to the right from the front end of the conductive main body 41, and the second bent part 432 bends to the left from the rear end of the conductive main body 41. The conductive shielding part 42 extends upward from the conductive main body 41 and is located between two adjacent partition plates 32 belonging to different insulating elements 3. Along the left-right direction, the conductive shielding part 42 completely shields the signal wiring part 21.

[0040] like Figure 3 As shown, the cable assembly 9 includes a grounding structure 92 and multiple signal lines 91. The signal lines 91 are connected to the upper surface 211 of the signal wiring section 21. The grounding structure 92 includes a shielding layer 921 and conductive silver paste 922.

[0041] like Figure 2 , Figure 3 and Figure 10 As shown, the conductive shielding member 5 includes a first conductive shielding member 51, a second conductive shielding member 52, and a third conductive shielding member 53. There are multiple first conductive shielding members 51, and each first conductive shielding member 51 corresponds to a signal terminal pair 20. Each first conductive shielding member 51 includes two side plates 511 and a connecting plate 512 connecting the two side plates 511. The two side plates 511 are located on the left and right sides of the signal wiring portion 21, respectively. The side plates 511 are fixed between the conductive shielding portion 42 and the partition plate 32 and are connected to the conductive shielding portion 42. The side plates 511 include wings 5111 extending rearward beyond the signal wiring portion 21. The connecting plate 512 is located on the upper side of the signal wiring portion 21. The connecting plate 512 has two through holes 5121 arranged perpendicular to the connecting plate 512, with each through hole 5121 overlapping a corresponding signal wiring portion 21. The design of the through holes 5121 can reduce the capacitance at the signal wiring portion 21, thereby adjusting the impedance of the signal wiring portion 21.

[0042] The second conductive shielding member 52 includes a first shielding part 521 and a second shielding part 522 that bends downward from the first shielding part 521. The first shielding part 521 connects to multiple connecting plates 512 and shields the through hole 5121. Specifically, the first shielding part 521 is fixed to multiple connecting plates 512 by welding or other means. The second shielding part 522 is located in front of the signal wiring part 21 and along the front-back direction, the projection of the second shielding part 522 overlaps with that of the signal body part 22. The lower end of the second shielding part 522 is recessed with multiple limiting holes 5221.

[0043] The third conductive shielding member 53 extends in the left-right direction and is located behind or below the signal wiring portion 21. The third conductive shielding member 53 includes a third shielding portion 531 and a fourth shielding portion 532. The extension direction of the third shielding portion 531 is the same as the extension direction of the signal wiring portion 21, and the third shielding portion 531 is located behind the signal wiring portion 21. The third conductive shielding member 53 is connected to the wings 5111 of the plurality of side plates 511. The fourth shielding portion 532 bends downward from the front end of the third shielding portion 531 and extends downward. The fourth shielding portion 532 is located at... The signal body 22 is located on the rear side and the signal wiring part 21 is located on the lower side. The third conductive shielding part 53 is integrally injection molded with the fixing strip 14. The third shielding part 531 exposes the upper surface of the fixing strip 14 and abuts against the multiple wings 5111. The fourth shielding part 532 exposes the front surface of the fixing strip 14. The conductive silver paste 922 fills the space enclosed by the third shielding part 531 and the multiple wings 5111, thereby connecting the third shielding part 531, the multiple wings 5111, the shielding layer 921 and the first shielding part 521.

[0044] The shielding component 6 includes a conductive shielding component 61, a first shielding component 62, and a second shielding component 63.

[0045] like Figure 4 and Figure 5 As shown, the conductive shielding component 61 includes a plate-shaped shielding body 611 and side portions 612 bent backward from both sides of the shielding body 611. The shielding body 611 is fixedly connected to multiple first bent portions 431 by means of laser spot welding or the like. The plate surface of the shielding body 611 is perpendicular to the plate surface of the conductive main body portion 41. The conductive shielding component 61 and the multiple conductive main bodies 41 form multiple receiving spaces 613. Similarly, a receiving space 613 is also formed between the side portions 612 and the conductive main bodies 41. The signal terminal pair 20 and the corresponding insulating component 3 are received in the receiving space 613. To improve the shielding effect, the conductive component 4 is not perforated, which prevents two adjacent insulating components 3 from being connected through the conductive component 4. To improve assembly efficiency and avoid the need to assemble the insulating components 3 one by one in subsequent assembly, a row of multiple insulating components 3, multiple signal terminal pairs 20, multiple conductive components 4, and conductive shielding component 61 are integrally injection molded, making a row of insulating components 3, a row of signal terminal pairs 20, conductive shielding component 61, and conductive components 4 into a whole. During assembly, a row of signal terminal pairs 20 can be assembled at once.

[0046] In this embodiment, to allow multiple insulating components 3, multiple signal terminal pairs 20, multiple conductive components 4, and conductive shielding components 61 to be integrally injection molded, the extensions 33 on the multiple insulating components 3 are first connected to the same auxiliary component. Then, a mold is placed through the space between two adjacent extensions 33 and the groove 311 to fix the signal terminal pairs 20 in the receiving space 613. Finally, plastic is filled into the receiving space 613 through the plastic flow channel of the auxiliary component, while multiple insulating components 3 are injection molded. Of course, in other embodiments, the auxiliary component can be omitted, and a glue inlet can be provided at the rear of each receiving space 613, through which the insulating components 3 are filled into the receiving space 613.

[0047] like Figure 3 and Figure 8 As shown, the first shielding member 62 includes a first shielding body 621, a blocking portion 622 extending forward from the lower end of the first shielding body 621, a first shielding portion 623 extending downward from the blocking portion 622, and a snap-fit ​​arm 624 disposed on the first shielding body 621; the first shielding body 621 is located at the front end of the signal body portion 22, the blocking portion 622 is located on the upper side of the extension portion 33, the blocking portion 622 overlaps with the connecting arm 232 in the vertical direction, and the first shielding portion 623 is located at... The front side of the signal flare arm 23 is shielded by the first shielding part 623 and the blocking part 622. The snap-fit ​​arm 624 includes a first part 6241 extending forward and a second part 6242 extending upward from the first part 6241. The first part 6241 is received in the limiting port 5221, and the second part 6242 abuts against the second conductive shielding member 52. The first shielding member 62 and the second conductive shielding member 52 are stably contacted by the cooperation between the snap-fit ​​arm 624 and the limiting port 5221.

[0048] In this embodiment, a row of signal terminal pairs 20 corresponds to a first shield 62. Each first shield 62 has only one first shield body 621. A first shield body 621 is provided with multiple snap-fit ​​arms 624. A first shield body 621 bends forward and extends to provide multiple shielding portions 622. Each shielding portion 622 extends downward to provide a first shielding portion 623. Each shielding portion 622 and a first shielding portion 623 are used to shield a corresponding signal terminal pair 20. There is a first fixing groove 626 between two adjacent first shielding portions 623 and between two adjacent shielding portions 622. The first fixing groove 626 is "L" shaped. There is a positioning groove 627 between two adjacent first extension arms 6231 belonging to different first shielding portions 623. The positioning groove 627 is connected to the first fixing groove 626. A first shielding part 623 extends forward with two first extension arms 6231. Each first extension arm 6231 is provided with a first elastic finger 6232. The two first elastic fingers 6232 extend from the two first extension arms 6231 towards each other in the left and right directions, and there is a gap space 625 between the two first elastic fingers 6232. That is, one first elastic finger 6232 extends to the left from the corresponding first extension arm 6231, and the other first elastic finger 6232 extends to the right from the corresponding first extension arm 6231. The ends of the two first elastic fingers 6232 approach each other and have a gap space 625.

[0049] Of course, in other embodiments, a first shield 62 may have only one shielding part 622 and one first shielding part 623. One shielding part 622 and one first shielding part 623 shield multiple signal terminal pairs 20. In other words, multiple shielding parts 622 connected together can be regarded as one shielding part 622, and multiple first shielding parts 623 connected together can be regarded as one first shielding part 623. Alternatively, a row of signal terminal pairs 20 may correspond to multiple first shielding parts 62, and each first shielding part 62 may correspond to one or more signal terminal pairs 20.

[0050] like Figure 2 , Figure 8 and Figure 9 As shown, the second shielding member 63 includes a second shielding body 631 and a second shielding portion 632 that bends downward from the second shielding body 631. The second shielding body 631 is located behind the signal body portion 22 and contacts the fourth shielding portion 532. The second shielding portion 632 is located behind the signal spring arm. The first shielding member 62 and the second shielding member 63 are respectively disposed on the front and rear sides of the signal body portion 22, with the first shielding member 62 in contact with the second conductive shielding member 52 and the second shielding member 63 in contact with the third conductive shielding member 53. The various shielding structures cooperate with each other to further improve the shielding effect on the signal terminals.

[0051] In this embodiment, a row of signal terminal pairs 20 corresponds to a second shield 63. Each second shield 63 has only one second shielding body 631. Each second shielding body 631 extends downwards with multiple second shielding portions 632. Each second shielding portion 632 is used to shield a corresponding signal terminal pair 20. A second fixing groove 633 is provided between two adjacent second shielding portions 632. Each second shielding portion 632 extends rearward with a second extension arm 6321. The second extension arm 6321 extends to the left and right with second elastic fingers 6322, respectively.

[0052] Of course, in other embodiments, a second shield 63 may have only one second shield 632, and a second shield 632 may shield multiple signal terminal pairs 20. Alternatively, multiple second shields 632 connected together may be considered as one second shield 632. Or, a row of signal terminal pairs 20 may correspond to multiple second shields 63, and each second shield 63 may correspond to one or more signal terminal pairs 20.

[0053] like Figure 6 , Figure 7 and Figure 11 As shown, the grounding component 8 is located below the first shielding component 62 and the second shielding component 63, and includes a grounding body 81 and a spring arm. In the front-back direction, the grounding body 81 is located between two rows of signal terminal pairs 20, and the grounding body 81 includes a plurality of fixing parts 811 and a first elastic abutting part 86 and a second elastic abutting part 87 located between two adjacent fixing parts 811. The spring arm includes a first spring arm 82 extending forward from the fixing part 811 and a second spring arm 83 extending backward from the grounding body 81. The first spring arm 82 and the second spring arm 83 are each provided with a grounding contact part 821 that elastically abuts against the circuit board. Each first elastic arm 82 extends forward with two third elastic abutment portions 88, and there is a forward-facing slot 89 between the two third elastic abutment portions 88. The front ends of two adjacent first elastic arms 82 are connected by a first connecting portion 84. The first connecting portion 84 extends forward with a first elastic abutment portion 86. The rear ends of two adjacent second elastic arms 83 are connected by a second connecting portion 85. The second connecting portion 85 extends backward with a second elastic abutment portion 87. The first elastic abutment portion 86, the second elastic abutment portion 87, and the third elastic abutment portion 88 all abut downward with the circuit board. The first elastic abutment portion 86 abuts upward with the first elastic finger 6232, the second elastic abutment portion 87 abuts upward with the second elastic finger 6322, and the third elastic abutment portion 88 abuts upward with the first extension arm 6231.

[0054] Setting multiple elastic abutment portions can increase the contact points between the grounding component 8 and the docking component, and add shielding in the left and right directions of the signal contact portion 2331 to further enhance the shielding effect of the signal contact portion 2331, improve crosstalk, and improve signal integrity. The slot 89 allows the two third elastic abutment portions 88 to separate, so that they will not affect each other when they abut with the docking component. Similarly, the slot 89 also allows the two adjacent first elastic abutment portions 86 in the left and right directions to separate, reducing their mutual influence.

[0055] The signal terminal pairs 20, the first shielding part 623, and the second shielding part 632 are arranged in four rows along the front-to-back direction. A second extension arm 6321 of the first row is received in the spacing space 625. The second elastic finger 6322 on the second shielding part 632 of the first row and the first elastic finger 6232 on the first shielding part 623 of the second row are located between the two rows of signal terminal pairs 20, and the second elastic finger 6322 on the second shielding part 632 of the first row is located behind the first elastic finger 6232 on the first shielding part 623 of the second row. The grounding body 81 is provided with a first elastic abutment part 86 extending to the right and a second elastic abutment part 87 extending to the left. The first elastic abutment part 86 corresponds one-to-one with the first elastic finger 6232 on the first shielding part 623 of the second row, and the second elastic abutment part 87 corresponds one-to-one with the second elastic finger 6322 on the second shielding part 632 of the first row.

[0056] A first elastic abutment 86 on the first connecting part 84 simultaneously abuts against two first elastic fingers 6232 on a first shielding part 623 in the first row. Two second elastic abutment parts 87 on the second connecting part 85 abut against two spaced second elastic fingers 6322 on a second shielding part 632 in the second row, respectively. Along the front-rear direction, the projection of the signal flare arm 23 overlaps with the projection of the first elastic abutment 86 and the projection of the second elastic abutment 87.

[0057] The first elastic abutment portion 86 extends to the right, the second elastic abutment portion 87 extends to the left, and the signal spring arm 23 extends along the first direction, which is perpendicular to the left and right directions. As a result, on the mating surface with the circuit board, the directions of the forces exerted by the first elastic abutment portion 86, the second elastic abutment portion 87, and the signal contact portion 2331 on the circuit board are different, thereby preventing the circuit board from shifting due to these forces and making the abutment more stable.

[0058] The grounding component 8 includes a first grounding component 8A and a second grounding component 8B. The first grounding component 8A is located below the first shielding component 62 in the first and second rows, and the second grounding component 8B is located below the first shielding component 62 in the third and fourth rows. The first grounding component 8A and the second grounding component 8B have the same structure. The first spring arm 82 of the first grounding component 8A is located between two adjacent signal terminal pairs 20 in the first row, and the second spring arm 83 of the first grounding component 8A is located between two adjacent signal terminal pairs 20 in the second row. The first spring arm 82 of the second grounding component 8B is located between two adjacent signal terminal pairs 20 in the third row, and the second spring arm 83 of the second grounding component 8B... 3. Located between two adjacent signal terminal pairs 20 in the fourth row, the second connecting part 85 of the first grounding member 8A and the first connecting part 84 of the second grounding member 8B are located between the second row of signal terminal pairs 20 and the third row of signal terminal pairs 20. The first elastic abutting part 86 of the first connecting part 84 of the second grounding member 8B is located between two adjacent second elastic abutting parts 87 of the second connecting part 85 of the first grounding member 8A. In short, between the second row of signal terminal pairs 20 and the third row of signal terminal pairs 20, the first elastic abutting part 86 of the second grounding member 8B is located between two adjacent second elastic abutting parts 87 of the first grounding member 8A.

[0059] like Figure 7 , Figure 9 and Figure 11 As shown, there are multiple conductive strips 7. Each conductive strip 7 includes a first conductive segment 71 located between two adjacent signal terminal pairs 20 in the first row, a second conductive segment 72 located between two adjacent signal terminal pairs 20 in the second row, and a connecting segment 73 connecting the first conductive segment 71 and the second conductive segment 72. A limiting groove 331 is provided between two extensions 33 belonging to different insulating members 3. The first conductive segment 71 and the second conductive segment 72 are received in the limiting groove 331. The limiting groove 331 is located between the first fixing groove 626 and the second fixing groove 633. The first conductive segment 71... 1. A first fixed groove 626 and a second fixed groove 633 are fixed in the first row. A second conductive segment 72 is fixed in the first fixed groove 626 and the second fixed groove 633 in the second row. The first conductive segment 71 includes two overlapping portions 711 and a mating portion 712 located between the two overlapping portions 711. The two overlapping portions 711 are in contact with the first elastic arm 82. The mating portion 712 is directly opposite the grounding contact portion 821 and extends downward beyond the two overlapping portions 711. The second conductive segment 72 has the same structure as the first conductive segment 71 and is mated with the second elastic arm 83. A connecting segment 73 is positioned in a positioning groove 627. The lower surface of the connecting segment 73 is substantially flush with the lower surfaces of the two first extension arms 6231 that form the positioning groove 627. The lower surface of the connecting segment 73 and the lower surfaces of the two first extension arms 6231 form a welding surface 731. The fixing portion 811 of the grounding member 8 is welded to the welding surface 731.

[0060] Each conductive strip 7 includes a first conductive segment 71, a second conductive segment 72, and a connecting segment 73. A positioning groove 627 is formed between the two first extension arms 6231 to limit the first conductive segment 71 and the second conductive segment 72, so that one conductive strip 7 can simultaneously connect the first shielding part 623 and the second shielding part 632 of the first row and the second row and facilitate assembly. In addition, the lower surface of the connecting segment 73 and the lower surface of the two first extension arms 6231 form a welding surface 731 to be welded to the grounding body 81. While fixing the grounding body 81, the grounding body 81 can also connect the two first extension arms 6231 and the connecting segment 73 to improve the shielding effect.

[0061] In summary, this utility model has the following effects:

[0062] 1. This application forms multiple receiving spaces 613 by cooperating the conductive shielding member 61 with the conductive main body 41 to receive multiple insulating members 3 and multiple signal terminal pairs 20. Compared with the prior art solution, it is not necessary to separately manufacture multiple shielding shells, which can save manufacturing costs. In addition, the conductive member 4 is connected to the conductive shielding member 61 through a bending part. The conductive member 4 has no holes, so the shielding effect of the conductive member 4 on the signal terminal pairs 20 is better. On the other hand, this structure allows multiple insulating members 3, multiple signal terminal pairs 20, multiple conductive members 4, and conductive shielding member 61 to be integrally injection molded. That is to say, a row of signal terminal pairs 20 is a whole. During assembly, a row of signal terminal pairs 20 can be assembled at one time, without assembling them one by one, which greatly improves the assembly efficiency.

[0063] 2. By setting the first conductive shielding member 51, the second conductive shielding member 52, and the third conductive shielding member 53, each signal wiring part 21 has conductive shielding members in five directions: the front, the top, the left and right sides, and the bottom or rear side. This avoids interference to the signal transmitted by the signal wiring part 21 in as many directions as possible. Furthermore, the second conductive shielding member 52 is connected to the first conductive shielding member 51, and the third conductive shielding member 53 is connected to multiple side plates 511. That is to say, the third conductive shielding member 53 and the second conductive shielding member 52 are connected to multiple first conductive shielding members 51, and the three are electrically interconnected, which makes the overall shielding effect better and further improves signal integrity.

[0064] 3. Connecting the shielding layer 921, the wing 5111 and the third conductive shielding member 53 with conductive silver paste 922 can increase the grounding loop and improve the shielding effect. In addition, the wing 5111 extends backward beyond the signal wiring part 21 to prevent the conductive silver paste 922 from contacting the signal wiring part 21, thereby preventing short circuit.

[0065] 4. By setting the first shielding member 62 and the second shielding member 63 to shield the signal terminal in the front and rear directions, and setting the grounding member 8 below the first shielding member 62 and the second shielding member 63, the grounding member 8 has a first elastic abutment part 86 and a second elastic abutment part 87 to abut downward against the mating element, which can enhance the shielding effect at the signal contact part 2331. The first elastic abutment part 86 abuts upward against the first elastic finger 6232, and the second elastic abutment part 87 abuts upward against the second elastic finger 6322. That is to say, the grounding member 8 has multiple points of contact with the first shielding member 62 and the second shielding member 63, and the three are electrically connected to form multiple grounding loops, which further improves the shielding effect of the signal terminal. Regarding the shielding effect of component 2, on the other hand, the first elastic finger 6232 will give the first elastic abutment part 86 a downward elastic force, and the second elastic finger 6322 will give the second elastic part a downward elastic force. This makes the elastic force of the first elastic abutment part 86 and the second elastic abutment part 87 better when they abut against the docking element, and the abutment with the docking element is more stable. The first elastic finger 6232 and the second elastic finger 6322 are distributed on the first shielding component 62 and the second shielding component 63. That is to say, the force given to the grounding component 8 by the first elastic finger 6232 and the second elastic finger 6322 is distributed in various parts of the grounding component 8, further making the abutment between the grounding component 8 and the docking element more stable.

[0066] 5. The first shielding part 623 is provided with two first extension arms 6231, and the second shielding part 632 is provided with one second extension arm 6321. Two first elastic fingers 6232 extend from the two first extension arms 6231 towards each other in the left and right directions. The second extension arm 6321 is housed in the space 625 between the two first elastic fingers 6232. The second extension arm 6321 extends to the left and right with second elastic fingers 6322. This design can improve the space utilization between the second shielding part 632 in the first row and the first shielding part 623 in the second row, so that more elastic fingers can be set in a limited space, allowing the grounding member 8 to have more contact points with the first shielding member 62 and the second shielding member 63. In addition, when the first elastic fingers 6232 and the second elastic fingers 6322 abut against the grounding member 8, the first extension arm 6231 and the second extension arm 6321 will extend the lever arm length of the first elastic fingers 6232 and the second elastic fingers 6322, thereby making the elasticity of the first elastic fingers 6232 and the second elastic fingers 6322 better.

[0067] 6. The front ends of the two first elastic arms 82 are connected by a first connecting part 84. The first connecting part 84 extends forward to a first elastic abutment part 86. The rear ends of the two second elastic arms 83 are connected by a second connecting part 85. The second connecting part 85 extends backward to a second elastic abutment part 87. This design ensures that when the first elastic abutment part 86 and the second elastic abutment part 87 abut with the docking element, the actual lever arm length of the first elastic abutment part 86 is the length of the first elastic abutment part 86 plus the length of the first elastic arm 82, and the actual lever arm length of the second elastic abutment part 87 is the length of the second elastic abutment part 87 plus the length of the second elastic arm 83, thereby enhancing the elasticity of the first elastic abutment part 86 and the second elastic abutment part 87.

[0068] 7. The first elastic abutment portion 86 of the second grounding member 8B is located between two adjacent second elastic abutment portions 87 of the first grounding member 8A, so that the first grounding member 8A and the second grounding member 8B cooperate with each other, so that multiple elastic abutment portions can be arranged between the grounding member 8 and the second row of signal terminal pairs 20 and the third row of signal terminal pairs 20. Furthermore, the simultaneous abutment of a first elastic abutment portion 86 with two first elastic fingers 6232 on a first shielding portion 623 can also increase the grounding loop between the grounding member 8 and the first shielding portion 62, thereby improving the shielding effect.

[0069] 8. By fixing the conductive strip 7 between two adjacent signal terminal pairs 20 through the first fixing groove 626 and the second fixing groove 633, the shielding of the signal terminal pairs 20 can be enhanced in the left and right directions, and the crosstalk between two adjacent signal terminal pairs 20 can be reduced. The conductive strip 7 is electrically connected to the first shielding member 62 and the second shielding member 63, so that the conductive strip 7, the first shielding member 62 and the second shielding member 63 are at the same potential, thereby enhancing the shielding effect.

[0070] The conductive strip 7 is provided with two overlapping portions 711 that contact the spring arm of the grounding component 8, which can increase the grounding loop between the spring arm of the grounding component 8 and the conductive strip 7 and reduce crosstalk. In addition, compared with the two overlapping portions 711 being flatly connected, a mating portion 712 is provided that extends downward beyond the two overlapping portions 711. This allows the grounding contact portion 821 to be closer to the conductive strip 7 after it contacts the mating element, or even stick together, further enhancing the shielding effect of the grounding component 8.

[0071] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
