[0036] Please note that the above description of the directions of the first signal terminals 4 and the first ground terminals 5 is only for one row. For the other row, the direction description of some structures may be different from the above description (for example, the extension directions of the first signal pins 43 in the two rows are opposite), but since the structures are the same, they will not be repeated.

[0037] like Figure 2 , Figure 6 and Figure 8 As shown, the grounding component 3 includes a base 31, a docking portion 32 extending downward from the base 31, an extension portion 33 extending forward from the base 31, a convex rib 35 extending forward from the base 31, a first limiting wall 36 extending forward from the left and right ends of the base 31 respectively, two second limiting walls 37 extending toward each other from the two first limiting walls 36, and a compensation portion 34, wherein the compensation portion 34 is located between the extension portion 33 and the docking portion 32, wherein the compensation portion 34 is provided with an inclined surface, one end of the inclined surface is connected to the docking portion 32, and the other end is connected to the extension portion 33; in the present embodiment, the grounding component 3 is a metal part formed by powder metallurgy or die casting, and of course in other embodiments, it can also be a component formed by stamping or other methods for grounding or shielding.

[0038] like Figure 2 , Figure 4 and Figure 8As shown, two rows of first signal terminals 4 and first grounding terminals 5 are respectively located on the front and rear sides of the docking portion 32, and both include a first insulating member 2 for fixing the plurality of first signal terminals 4 and the plurality of first grounding terminals 5.

It is worth noting that, in fact, the grounding member 3 is provided with two first limiting walls 36 and two second limiting walls 37 corresponding to each first insulating member 2. The setting method is as described above. Since the structure is roughly the same, only one of the first insulating members 2 is described here. The front and rear ends of a first insulating member 2 are respectively accommodated in the two limiting grooves 38, thereby fixing the relative positions of the first insulating member 2 and the grounding member 3.

[0039] like Figure 8 As shown, the first grounding body abuts the extension portion 33 backward, the first signal body portion 41 and the first grounding body portion 51 are staggered front to back, and along the left-right direction, the projection of the first signal body portion 41 overlaps with the projection of the extension portion 33 .

[0040] like Figure 3 and Figure 8 As shown, the second connector 200 includes a second insulating shell P, and a shielding member 7, a plurality of second signal terminals 8, and a plurality of second grounding terminals 9 accommodated in the second insulating shell P. The plurality of second signal terminals 8 and the plurality of second grounding terminals 9 are arranged in a row along the left-right direction. The second connector 200 in this embodiment is provided with two rows spaced apart along the front-back direction, wherein the arrangement order of the plurality of second signal terminals 8 and the plurality of second grounding terminals 9 in each row is that one second grounding terminal 9 and a pair of second signal terminals 8 are alternately arranged, and the pair of second signal terminals 8 are used to transmit differential signals. Of course, in other embodiments, the number of second grounding terminals 9 between the two pairs of second signal terminals 8 can also be set to two, or the arrangement order of the plurality of second signal terminals 8 and the plurality of second grounding terminals 9 in a row is that one second grounding terminal 9 and one second signal terminal 8 are alternately arranged, and one of the second signal terminals 8 is used to transmit a single-ended signal. The utility model is not limited to this. The second connector 200 of the utility model is also provided with a metal shell Q located outside the second insulating shell P to cover the second insulating shell P.

[0041] like Figure 3 , Figure 6 and Figure 8As shown, since the structures of the second signal terminals 8 in the two rows are roughly the same, only one row is described here. Each second signal terminal 8 has a second signal main body 81, a second signal contact arm 82 extending upward from the second signal main body 81, and a second signal pin 83 extending downward from the second signal main body 81 or first bending downward and then bending forward. Please note that upward here means that the second signal contact arm 82 generally extends upward, but the second signal contact arm 82 is allowed to tilt in the forward and backward directions. The second signal pin 83 can be vertically arranged with the second signal main body 81, or can be arranged in the same vertical plane with the second signal main body 81, etc. The utility model does not limit the second signal pin 83. The second signal pin 83 is used to electrically connect with the PCB400. The electrical connection here is generally welded. Of course, in other embodiments, it can also be press-fitted.

[0042] like Figure 2 , Figure 4 and Figure 8 As shown, since the structures of the second grounding terminals 9 in the two rows are roughly the same, only one row is described here. Each second grounding terminal 9 has a second grounding body portion 91, a second grounding contact arm 92 extending upward from the second grounding body portion 91, and a second grounding pin 93 extending downward from the second grounding body portion 91 or first bending downward and then bending forward.

[0044] like Figure 3 and Figure 8As shown, only one row of multiple second signal terminals 8 and multiple second grounding terminals 9 is described. Each second signal contact arm 82 includes a second signal transition portion 821 and a second signal contact portion 822. The second signal transition portion 821 is formed by extending upward and backward from the second signal main body 81, and the second signal contact portion 822 is connected to the upper end of the second signal transition portion 821.

Along the left and right directions, the projection of the second signal main body 81 coincides with the projection of the second grounding main body 91, and the projection of the second signal transition portion 821 coincides with the projection of the second grounding transition portion 921.

[0045] Please note that the above description of the directions of the second signal terminals 8 and the second ground terminals 9 is only for one row. For the other row, the direction description of some structures may be different from the above description (for example, the extension directions of the second signal pins 83 in the two rows are opposite), but since the structures are the same, they will not be repeated.

[0046] like Figure 3 and Figure 8 As shown, each row of the second signal terminals 8 and the second ground terminals 9 is provided with a second insulating member 6. Each second insulating member 6 fixes the second signal terminals 8 and the second ground terminals 9 in a row, and each second insulating member 6 is provided with a groove 61 extending upward.

[0047] like Figure 5 , Figure 7 and Figure 8As shown, after the first connector 100 and the second connector 200 are plugged into each other, the first signal contact arm 42 abuts against the second contact position 811 of the second signal body portion 81, the first grounding contact arm 52 abuts against the second grounding body portion 91 backward, the second signal contact arm 82 abuts against the first contact position 411 of the first signal body portion 41, and the third contact position 321 of the docking portion 32 abuts against the second grounding contact arm 92 forward. In the left-right direction, the projection of the first contact position 411 partially overlaps with the projection of the first portion 331 of the extension portion 33, and in the left-right direction, the projection of the first portion 331 is substantially the same as the projection of the first portion 331. The width is greater than the width of other parts of the extension portion 33; in the up-down direction, the docking portion 32 is aligned with a portion of the groove 61; viewed in the front-to-back direction, the third contact position 321 is located between the first contact position 411 and the second contact position 811; viewed in the left-right direction, a portion of the second signal contact arm 82 overlaps with the extension portion 33; in the up-down direction, the projection of the extension portion 33 overlaps with a portion of the projection of the second grounding contact arm 92, and a portion of the projection of the rib 35 overlaps with a portion of the projection of the second signal contact arm 82; in the front-to-back direction, a portion of the base 31 is aligned with a portion of the second signal contact arm 82.

[0048] In summary, the utility model has the following beneficial effects:

[0049] 1. After the first connector 100 and the second connector 200 are plugged into each other, the first signal contact arm 42 abuts against the second signal terminal 8, the first ground contact arm 52 abuts against the second ground terminal 9, and the second signal contact arm 82 abuts against the first signal terminal 4

[0050] , viewed along the third direction, part of the second signal contact arm 82 overlaps with the extension portion 33, and the first grounding body portion 51 abuts against the extension portion 33 in a direction away from the second direction, so that part of the second signal contact arm 82 is shielded by the extension portion 33 in the third direction, and in the first direction, the projection of the extension portion 33 overlaps with the projection of part of the second grounding contact arm 92. In other words, part of the second grounding contact arm 92 is aligned with the extension portion 33 up and down, that is, in order to allow the extension portion 33 to be positioned, the extension portion 33 has enough space to be set so as to be sufficient to shield part of the second signal contact arm 82. The length of the second grounding terminal 9 in the first direction is set to be smaller than the length of the second signal terminal 8 in the first direction. Furthermore, while the shielding performance in the electrical connector assembly 1000 is improved by the provision of the extension portion 33, the second grounding contact arm 92 is also abutted against the docking portion 32. In other words, the second grounding terminal 9 is not only abutted against the first grounding terminal 5, but also abutted against the docking portion 32 of the grounding member 3, thereby increasing the grounding loop inside the electrical connector assembly 1000 and improving the overall signal integrity performance (SI performance) of the electrical connector assembly 1000.

[0051] 2. Although the second grounding terminal 9 is not exactly the same in shape as the second signal terminal 8 because it avoids the extension portion 33, in the third direction, the projection of the second signal main portion 81 coincides with the projection of the second grounding main portion 91, and the projection of the second signal transition portion 821 coincides with the projection of the second grounding transition portion 921, that is, the second grounding terminal 9 still tries to shield the second signal terminal 8 to the maximum extent, thereby optimizing the shielding performance of the second connector 200 and improving the SI performance of the second connector 200.

[0052] 3. Along the third direction, the projection of the first signal main body 41 coincides with the projection of the extension portion 33, that is, in the third direction, the extension portion 33 can shield the first signal main body 41, thereby shielding and absorbing the electromagnetic field radiated outward from the first signal terminal 4 to the first signal main body 41, and at the same time, it can also shield and absorb external noise interference to the first signal main body 41, thereby optimizing the shielding performance of the first connector 100 and improving its SI performance.

[0053] 4. The first signal terminal 4 and the first grounding terminal 5 are fixed in the first insulating member 2. The first insulating member 2 cooperates with the limiting groove 38 of the grounding member 3 to fix the positions of the grounding member 3 and the first insulating member 2 to each other. From the perspective of the first signal terminal 4, the first grounding terminal 5, the first insulating member 2, and the grounding member 3 as a whole, the matching stability between the structures is relatively high, thereby improving the structural stability of the first connector 100, which is beneficial to improving the service life of the first connector 100 and ensuring a stable electrical connection.

[0054] 5. Along the first direction, the partial projection of the rib 35 overlaps with the partial projection of the second signal contact arm 82, and along the second direction

[0055] , a portion of the base 31 is aligned with a portion of the second signal contact arm 82 along the second direction, so that the second signal contact arm 82 can be shielded by the base 31 and the rib 35, thereby optimizing the overall shielding performance of the electrical connector assembly 1000 to improve its SI performance.

[0056] 6. The ribs 35 can optimize the overall shielding performance of the electrical connector assembly 1000 and can also be used with the first connector 10

[0057] 0, the steps 21 of the first insulating member 2 for fixing the first signal terminal 4 and the first ground terminal 5 cooperate to limit each other, so that the internal space of the first connector 100 is fully utilized, which is conducive to the miniaturization of the first connector 100.

[0058] 7. The arrangement of the compensation portion 34 increases the area of ​​the extension portion 33, thereby improving the shielding performance of the grounding member 3 (

[0059] The setting of the inclined surface ensures that the setting of the compensation portion 34 will not hinder the cooperation between the second grounding terminal 9 and the docking portion 32. In other words, without affecting the normal overlap between the second grounding terminal 9 and the docking portion 32, the utility model maximizes (compensates) the shielding performance of the grounding component 3 to optimize the SI performance of the first connector 100.

[0060] 8. In terms of the total signal transmission path length between the first signal terminal 4 and the second signal terminal 8, the impedance at the first contact position 411 is lower than that at other positions, which is called impedance mutation. The impedance mutation will cause the reflection of electromagnetic waves and thus generate return loss, and the reflected electromagnetic waves will affect other adjacent first signal terminals 4.

[0061] , the second signal terminal 8 causes noise interference, and at the impedance mutation position, that is, at the first contact position 411, the extension portion 33 of the grounding member 3 is widened to absorb more noise interference, so as to optimize the performance of the first connector 100SI.

[0062] 9. Along the first direction, part of the groove 61 is aligned with the docking portion 32. In other words, the groove 61 is provided to prevent the docking portion 32 from abutting against the second insulating member 6 when the first signal terminal 4 and the first grounding terminal 5 are not respectively connected to the second signal terminal 8 and the second grounding terminal 9 during the mutual plugging process of the first connector 100 and the second connector 200. The groove 61 plays a role of giving way to avoid damage to the second insulating member 6.

[0063] 10.
