Description

[Technical field]

[0001] The invention relates to an electric connector assembly, in particular to an electric connector assembly which can avoid short circuit between a terminal and a shielding shell. [Background technology]

[0002] There is an electrical connector assembly, which includes an electrical connector and a docking connector, wherein the electrical connector is provided with a first shielding shell surrounding the outside of a pair of first signal terminals, the pair of first signal terminals are arranged in the left-right direction, and the first shielding shell has two spring plates, the two spring plates correspond to the pair of first signal terminals, and the docking connector is provided with a second shielding shell surrounding the outside of a pair of second signal terminals. When the electrical connector and the docking connector are docked in the front-to-back direction, the first shielding shell extends into the second shielding shell so that the inner wall of the second shielding shell abuts against the two spring plates, and the pair of second signal terminals extends into the first shielding shell so that in the up-down direction, the pair of second signal terminals are located between the pair of first signal terminals and the two spring plates, and the pair of second signal terminals and the pair of first signal terminals are docked, so that signals can be transmitted between the electrical connector and the docking connector.

[0003] However, since the two spring sheets are arranged corresponding to a pair of the first signal terminals, and when the electrical connector and the docking connector are plugged in along the front-to-back direction, the first shielding shell extends into the second shielding shell, so that the inner wall of the second shielding shell abuts against the two spring sheets. Therefore, as the plugging goes deeper, the two spring sheets will gradually shift downward due to the abutting force of the second shielding shell. Because a pair of the second signal terminals are located between a pair of the first signal terminals and the two spring sheets in the up and down directions, the distance between the spring sheets and the second signal terminals will gradually decrease during the downward displacement process. This makes it easy for the spring sheets to contact the second signal terminals, causing a short circuit between the spring sheets and the first shielding shell, thereby affecting the signal transmission between the electrical connector and the docking connector.

[0004] Therefore, it is necessary to design an electrical connector assembly to solve the above technical problems. [Summary of the invention]

[0039] [Specific implementation method]

[0040] In order to better understand the content of the present invention, the present invention is further described in detail in conjunction with specific implementation schemes and drawings.

In this embodiment, the first electrical component 200 is a first substrate, and the second electrical component 200' is a second substrate. Of course, in other embodiments, the first electrical component 200 and the second electrical component 200' may both be cables, or the first electrical component 200 may be the first substrate and the second electrical component 200' may be a cable, or the first electrical component 200 may be a cable and the second electrical component 200' may be the second substrate. Of course, the first electrical component 200 and the second electrical component 200' may also be other electrical components, as long as they can be electrically connected to the corresponding electrical connector 100 or the docking connector 100' to transmit corresponding signals, and are not limited here.

[0042] like Figure 1 and Figure 2 As shown, this is an electrical connector 100 provided by an embodiment of the present invention, which is used for the docking connector 100' to be plugged in along the plug-in direction and connected to the corresponding first electrical component 200. The electrical connector 100 includes an insulating shell 1, a cover 2, a plurality of electrical modules 3 (of course, in other embodiments, the number of the electrical modules 33 may also be one or two) and two retaining plates 4 (of course, in other embodiments, the number of the retaining plates 4 may also be one or three, etc.). The plurality of electrical modules 3 are arranged in parallel and fixed to the insulating shell 1, the cover 2 covers and fixes the plurality of electrical modules 3, and the plurality of electrical modules 3 are also fixed and positioned to each other by the two retaining plates 4. The plug-in side of the electrical connector 100 is used for plugging the docking connector 100', and the installation side of the electrical connector 100 is used for connecting the first electrical component 200.

[0043] like Figures 1 to 5As shown, each of the electrical modules 3 includes an insulating module 5, two grounding plates 6 and eight first terminal components A (of course, in other embodiments, the number of the first terminal components A can be one, two or other numbers). Figure 5 and Figure 6 As shown, each of the first terminal components A has a first shielding shell 7, at least a pair of first signal terminals 8 and a first insulator 9. A pair of the first signal terminals 8 are fixed to the first insulator 9 (of course, in other embodiments, the first insulator 9 can fix multiple pairs of the first signal terminals 8).

For the convenience of description, the plug-in direction is marked as the L direction, the plug-in direction is the front-to-back direction, the thickness direction of the first signal terminal 8 is marked as the T direction, and the arrangement direction is marked as the R direction. In the attached Figures 1 to 6 In the figure, the thickness direction T is the left-right direction in the figure, and in Figures 11 to Fig.12 In the embodiment, the thickness direction T is the up-down direction.

[0044] like Figures 2 to 5 As shown, the insulating module 5 has two side surfaces arranged opposite to each other along the thickness direction, and four receiving grooves 51 are recessed from one side surface of the insulating module 5 toward the other side surface along the thickness direction (of course, the number of the receiving grooves 51 can be one, two or other numbers in other embodiments), wherein four first terminal assemblies A are arranged in a row, and the four first terminal assemblies A are respectively received in the four receiving grooves 51 recessed on one side surface of the insulating module 5. One of the grounding plates 6 is located outside the four first terminal assemblies A along the thickness direction, and the grounding plate 6 is electrically connected to the four first terminal assemblies A at the same time. Four receiving grooves 51 are recessed on the other side surface of the insulating module 5 toward one side surface (of course, the number of the receiving grooves 51 can be one, two or other numbers in other embodiments), and are spaced from the four receiving grooves 51 recessed on one side surface of the insulating module 5. Another four first terminal assemblies A are arranged in a row, and are respectively received in the four receiving grooves 51 recessed on the other side surface of the insulating module 5. Another grounding plate 6 is located on one side of the other four first terminal assemblies A along the thickness direction, and the grounding plate 6 is located outside the other four first terminal assemblies A, and the grounding plate 6 is electrically connected to the other four first terminal assemblies A at the same time.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, each of the first shielding shells 7 includes a first shielding body 71 and a second shielding body 72 which are mutually assembled along the thickness direction. The length of the first shielding body 71 along the plugging direction is greater than the length of the second shielding body 72. The first shielding body 71 has a first wall 73 and two first side walls 74 extending from the left and right sides of the first wall 73 by bending. The first wall 73 is provided with an elastic sheet 731 and a first escape space 732 is formed by penetrating from the first wall 73 along the thickness direction. The elastic sheet 731 is used to contact the docking connector 100'. The elastic sheet 731 is cantilevered. The elastic sheet 731 is gradually reduced toward one end close to the first escape space 732 along the plugging direction. The elastic sheet 731 is closer to the plugging side of the electrical connector 100 than the first escape space 732 along the plugging direction. A contact elastic arm 741 is respectively provided on the two first side walls 74. The contact elastic arm 741 is used to contact the docking connector 100'. The first shielding shell 7 is further provided with a plurality of positioning portions 742 . The plurality of positioning portions 742 are formed by bending and extending from the two first side walls 74 . The positioning portions 742 are used to buckle with the second shielding body 72 .

[0046] like Figure 4 , Figure 5 and Figure 6 As shown, the second shielding body 72 includes a second wall 75 and two second side walls 76 bent from the left and right sides of the second wall 75, and the first wall 73 and the second wall 75 are arranged opposite to each other along the thickness direction. The first wall 73 extends beyond the second wall 75 along the plugging direction. In other words, the first wall 73 is closer to the plugging side of the electrical connector 100 than the second wall 75, that is, the length of the first wall 73 along the plugging direction is greater than the length of the second wall 75. The first shielding body 71 and the second shielding body 72 are assembled with each other along the thickness direction to form a tubular structure. After the first shielding body 71 and the second shielding body 72 are assembled, the first wall 73 and the second wall 75 are arranged opposite to each other along the thickness direction, and the positioning portion 742 is fixed to the second wall 75, so that the first shielding body 71 and the second shielding body 72 are fixed to each other. The two first side walls 74 and the two second side walls 76 correspond one to one. Along the arrangement direction perpendicular to the plug-in direction and the thickness direction, the distance between the two second side walls 76 is smaller than the distance between the two first side walls 74, and the two second side walls 76 are respectively assembled on the inner sides of the two first side walls 74.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown in the figure, when the assembled first shielding body 71 and the second shielding body 72 are installed in any one of the receiving grooves 51, the first shielding body 71 is located inside the insulating module 5, and each of the first walls 73 is close to the inner wall surface of the corresponding receiving groove 51, the second shielding body 72 is exposed outside the receiving groove 51, and the second wall 75 is arranged opposite to the first wall 73 along the thickness direction. The plurality of positioning portions 742 of each first shielding body 71 are bent and extended from the first side wall 74 to the outside of the second wall 75, that is, the second wall 75 is located between the positioning portions 742 and the first wall 73 in the thickness direction, and the positioning portions 742 are welded to the outer surface of the second wall 75, and the outer surface of the second wall 75 is welded to the corresponding grounding plate 6. In this way, compared with the first shielding body 71 being located outside the electrical module 3, only one welding is required to fix the positioning portions 742, the grounding plate 6 and the first shielding body 71, so welding is convenient. The welding point between the first shielding body 71 and the second shielding body 72 is exposed on the outside of the electrical module 3, which not only makes it easy to observe whether the first shielding body 71 and the second shielding body 72 are fixed and stable, but also prevents the positioning portion 742 from interfering with the inner wall of the receiving groove 51 to wear the insulating module 5 or cause a large gap in the assembly, and also makes it smoother to insert the first terminal assembly A into the receiving groove 51, so that the first shielding body 71 is close to the corresponding inner wall surface of the receiving groove 51, which facilitates the installation of the first terminal assembly A. .

[0048] like Fig.10As shown, the spring piece 731 is provided with a connecting portion 7311 and a contact portion 7312, and the width of the connecting portion 7311 is greater than the width of the contact portion 7312. Along the plug-in direction, the connecting portion 7311 is closer to the plug-in side of the electrical connector 100 than the contact portion 7312, that is, the connecting portion 7311 is located at the front end of the contact portion 7312. The connecting portion 7311 and the contact portion 7312 are connected to each other. Specifically, one end of the connecting portion 7311 close to the plug-in side of the electrical connector 100 is connected to the first wall 73 of the first shielding body 71, and the other end is connected to the contact portion 7312. In other words, the front end of the connecting portion 7311 is connected to the first wall 73, and the rear end of the connecting portion 7311 is connected to the contact portion 7312. The abutting portion 7312 is bent along the thickness direction and extends along the plugging direction. Specifically, the abutting portion 7312 is bent toward the side away from the first signal terminal 8 along the thickness direction and extends along the plugging direction to be formed and protrude from the outer wall surface of the first shielding body 71 along the thickness direction, that is, the abutting portion 7312 is bent and extended upward. One end of the abutting portion 7312 away from the connecting portion 7311 along the plugging direction is located in the first avoidance space 732, and the abutting portion 7312 protrudes from the outer wall surface of the first wall 73 along the thickness direction. The abutting portion 7312 is used to contact the docking connector 100'.

[0049] like Figure 5 , Figure 6 , Fig.10 , Fig.11 and Fig.12 As shown, the first avoidance space 732 is formed by penetrating from the first wall 73 along the thickness direction, and the number of the first avoidance space 732 is one (of course, in other embodiments, the number of the first avoidance space 732 can be two, three or other numbers, as long as the second terminal assembly B can be avoided), and a first expansion hole 7321 is provided at the end of the first avoidance space 732 close to the first signal terminal 8, and the aperture of the first expansion hole 7321 along the thickness direction is larger than the aperture of the first avoidance space 732 away from the first signal terminal 8, that is, the aperture of the first avoidance space 732 on the inner side of the thickness direction is larger than the aperture of the first avoidance space 732 on the outer side, so that the first avoidance space 732 has a larger aperture on the side close to the first signal terminal 8, so that the first avoidance space 732 can better make way for the docking connector 100'. Along the plugging direction, the elastic sheet 731 is closer to the plugging side of the electrical connector 100 than the first avoidance space 732 , and the free end of the abutting portion 7312 is located in the first avoidance space 732 .

[0050] like Figure 5 and Figure 6 As shown, a pair of first signal terminals 8 are arranged along the arrangement direction perpendicular to the plug-in direction and the thickness direction. Each of the first signal terminals 8 has a first contact portion 81, a first fixing portion 82 and a first welding portion 83. The first fixing portion 82 is located between the first welding portion 83 and the first contact portion 81, and one end of the first fixing portion 82 is connected to the first welding portion 83, and the other end is connected to the first contact portion 81. Each of the first fixing portions 82 is buried and fixed in the first insulator 9, and each of the first contact portions 81 is exposed outside the first insulator 9. Specifically, at least a portion of the first contact portion 81 protrudes out of the first insulator 9 along the plug-in direction and is exposed outside the first insulator 9. A portion of the first contact portion 81 close to one end of the first fixing portion 82 is blocked by the first insulator 9 and has a contact surface exposed outside the first insulator 9; each of the first welding portions 83 is also exposed in the first insulator 9.

[0051] like Fig.11 and Fig.12 As shown, the plugging direction is the front-to-back direction. Fig.11 and Fig.12 The thickness direction is the up-down direction. Along the plug-in direction, the front end of the first wall 73 extends forward beyond the first contact portion 81, and each of the first contact portions 81 along the plug-in direction has a first contact segment 811 and a first head 812 that bends upward and extends from the first contact segment 811. Along the plug-in direction, the first contact segment 811 is located between the first head 812 and the first fixed portion 82, and one end of the first contact segment 811 is connected to the first head 812, and the other end is connected to the first fixed portion 82. A groove 8111 is concavely provided on one side of the free segments of a pair of the first contact portions 81 facing each other along the arrangement direction, and the free segments of the first contact portions 81 along the plug-in direction include the first head 812 and a portion of the first contact segment 811 away from the first insulator 9. The groove 8111 is recessed from the first contact section 811 along the plugging direction and extends to the first head 812 . The recessed length of the groove 8111 along the plugging direction is smaller than the length of the first contact portion 81 . The two grooves 8111 are arranged opposite to each other.

[0052] like Fig.11 and Fig.12As shown, each of the first contact segments 811 is provided with a supporting portion 8112 and a suspended portion 8113. The supporting portion 8112 is located at one end of the suspended portion 8113 away from the first head 812 along the plugging direction, that is, one end of the supporting portion 8112 along the plugging direction is connected to the first fixing portion 82, and the other end is connected to the suspended portion 8113. The supporting portion 8112 is arranged opposite to the first insulator 9 along the thickness direction. The distance between the two supporting portions 8112 along the arrangement direction is greater than the distance between the two suspended portions 8113, and the projection of the abutting portion 7312 observed along the thickness direction is located between the projections of the two supporting portions 8112. In this way, the abutting portion 7312 is offset from the two first signal terminals 8 in the arrangement direction, so that even if the abutting portion 7312 is offset toward the side close to the first signal terminal 8 by the abutting force of the docking connector 100', the abutting portion 7312 will not contact the first signal terminal 8, thereby causing a short circuit between the first signal terminal 8 and the first shielding body 71.

[0053] like Figure 5 , Fig.11 and Fig.12 As shown, the first insulator 9 is provided with two first blocks 91 corresponding to a pair of the first signal terminals 8. The two first blocks 91 are respectively opposite to the two support portions 8112 along the thickness direction, and the two first blocks 91 respectively block the support portions 8112 of a pair of the first contact portions 81 from the first avoidance space 732 along the thickness direction. The support portion 8112 of the first contact segment 811 is exposed outside the first insulator 9, that is, one side of the support portion 8112 is exposed outside the first insulator 9 to form a contact surface, and the other side is blocked by the first block 91, and the suspended portion 8111 and the first head 812 of the first contact segment 811 both protrude out of the first insulator 9 along the plug-in direction (of course, in other embodiments, the first contact portion 81 may also protrude out of the first insulator 9, that is, the support portion 8112, the suspended portion 8111 and the first head 812 all protrude out of the first insulator 9 along the plug-in direction). When the first contact portion 81 is subjected to the abutting force of the docking connector 100 ′, the two first stoppers 91 are used to stop the first contact portion 81 from moving toward the side close to the second wall 75 , that is, each first stopper 91 stops the corresponding support portion 8112 from moving toward the side away from the second wall 75 .

[0054] like Figure 7 and Figure 8As shown, the docking connector 100' includes a plastic base 1', a plurality of shielding sheets 2' and a plurality of second terminal assemblies B (of course, in other embodiments, the number of the second terminal assemblies B may also be one or two, etc.). The plastic base 1' has a plug interface 11', and the plug interface 11' is used for the electrical connector 100 to be plugged in. The plurality of second terminal assemblies B and the plurality of shielding sheets 2' are all fixed in the plastic base 1', and the second head 416' of each second terminal assembly B is exposed at the plug interface 11'. The plurality of second terminal assemblies B are arranged in a plurality of rows along the thickness direction, and each of the shielding sheets 2' is connected to one side of the plurality of second terminal assemblies B in the same row, and the shielding sheet 2' is connected to the plurality of second terminal assemblies B in the same row. Four snap grooves 12' are provided along the plastic base 1' (of course, the number of snap grooves 12' can be two, three, etc. in other embodiments), and the four snap grooves 12' are grouped in pairs along the thickness direction and are respectively located on both sides of the plug port 11'. A suction cover 1" has a flat plate portion 11" and four snap arms 12". The four snap arms 12" are grouped in pairs along the thickness direction and are respectively located on both sides of the flat plate portion 11". The four snap arms 12" correspond to the four snap grooves 12', and each snap arm 12" is convexly provided with a snap block (not numbered) to snap with the corresponding snap groove 12'.

[0055] like Figure 8 As shown, each of the second terminal components B has a second shielding shell 3', a pair of second signal terminals 4' and a second insulator 5'. The pair of second signal terminals 4' are fixed to the second insulator 5'. The second shielding shell 3' is arranged around the outer side of the pair of second signal terminals 4' and the second insulator 5'. In the present embodiment, the second insulator 5' fixes a pair of second signal terminals 4'. In other embodiments, the second insulator 5' may also fix multiple pairs of second signal terminals 4'.

[0056] like Figures 8 to 12As shown, the second shielding shell 3' is provided with a first outer wall 31' and a second outer wall 32' in the thickness direction, and a second escape space 33' is formed by penetrating from the second outer wall 32' in the thickness direction. The second escape space 33' is two through holes (not numbered, the same below) spaced apart in the arrangement direction. The second outer wall 32' also has a fence 34', which is located between the two through holes in the arrangement direction, and the width of the fence 34' in the arrangement direction is less than the distance between the edges of the two grooves 8111. The shielding sheet 2' covers the outer side of the second outer wall 32' and shields part of the second escape space 33'. Specifically, the shielding sheet 2' shields parts of the two through holes. A second expansion hole 331' is provided at one end of each through hole close to the second signal terminal 4', and the aperture of each second expansion hole 331' in the thickness direction is larger than the aperture of the through hole away from the second signal terminal 4'. In this way, the through hole has a larger aperture on the side close to the second signal terminal 4 ′, so that the second avoidance space 33 ′ can better provide space for the two first heads 812 .

[0057] like Fig.10 , Fig.11 and Fig.12 As shown, the butt end of the second shielding shell 3' is bent along the thickness direction and extends a plurality of arc-shaped guide portions 35' along the plug-in direction (of course, in other embodiments, the number of the arc-shaped guide portions 35' may be one, two or other numbers). Specifically, each wall of the butt end of the second shielding shell 3' is bent upward and extends along the plug-in direction to have one arc-shaped guide portion 35', and the arc-shaped guide portion 35' of the first outer wall 31' is arranged opposite to the abutment portion 7312 along the plug-in direction. The bending direction of the arc-shaped guide portion 35' of the first outer wall 31' and the bending direction of the abutment portion 7312 complement each other, so that the arc-shaped guide portion 35' of the first outer wall 31' can guide the abutment portion 7312, so that the abutment portion 7312 abuts against the inner wall surface of the second shielding shell 3' along the thickness direction, which facilitates the docking of the electrical connector 100 and the docking connector 100'.

[0058] like Figure 8 , Fig.11 and Fig.12As shown, a pair of the second signal terminals 4' are arranged along the arrangement direction, and each of the second signal terminals 4' has a second contact portion 41', a second fixing portion 42' and a second soldering portion 43'. The second fixing portion 42' is located between the second soldering portion 43' and the second contact portion 41' along the plugging direction, and one end is connected to the second soldering portion 43', and the other end is connected to the second contact portion 41'. Each of the second fixing portions 42' is buried and fixed in the second insulator 5', each of the second contact portions 41' is exposed outside the corresponding second insulator 5', and each of the second soldering portions 43' is also exposed in the second insulator 5'.

[0059] like Fig.11 and Fig.12 As shown, the plug-in direction is the front-to-back direction, and the thickness direction is the up-down direction. Each of the second contact portions 41' has a second contact segment 412' and a second head 413' extending from the second contact segment 412'. The second contact segment 412' is located between the second fixing portion 42' and the second head 413' along the plug-in direction, and the front end of the second contact segment 412' is connected to the second fixing portion 42', and the rear end of the second fixing portion 42' is connected to the second head 413'. The second head 413' is bent and extended upward, and the bending direction of the second head 413' is opposite to the bending direction of the first head 812, and the first avoidance space 732 is used to provide a space for the second head 413'.

[0060] like Fig.10 and Fig.11 As shown, a recessed portion 411' is respectively provided on one side of the free sections of a pair of the second contact portions 41' facing each other along the arrangement direction, that is, the recessed portion 411' is provided on the side of the second contact portion 41' away from the second fixing portion 42' along the plugging direction. The free section of the second contact portion 41' along the plugging direction includes the second head portion 413' and a portion of the second contact section 412' away from the second insulator 5'. The recessed portion 411' is recessed from the second contact section 412' and extends to the second head portion 413'. The recessed length of the recessed portion 411' along the plugging direction is less than the length of the second contact portion 41'. The two recessed portions 411' are arranged opposite to each other along the arrangement direction, and the distance between the recessed edges of the two recessed portions 411' along the arrangement direction is greater than the width of the abutting portion 7312 (of course, in other embodiments, the distance between the recessed edges of the two recessed portions 411' along the arrangement direction may also be equal to the width of the abutting portion 7312).

[0061] like Figure 8 , Fig.10 , Fig.11 and Fig.12 As shown, the second insulator 5' of the second terminal assembly B is provided with two second blocks 51' corresponding to a pair of the second signal terminals 4', and the two second blocks 51' are respectively located on the side of the pair of the second signal terminals 4' away from the second avoidance space 33'. At least part of the second contact portion 41' protrudes out of the second insulator 5'. Specifically, a part of the second contact segment 412' close to the second fixing portion 42' is stopped by the second block 51' and has a contact surface exposed outside the second insulator 5', and the other part of the second contact segment 412' and the second head 413' both protrude out of the second insulator 5' along the plug-in direction (of course, in other embodiments, the second contact portion 41' may also protrude out of the second insulator 5' along the plug-in direction, that is, the second contact segment 412' and the second head 413' both protrude out of the second insulator 5' along the plug-in direction). When the second contact portion 41 ′ is subjected to the abutting force of the first contact portion 81 , the two second stoppers 51 ′ stop the second contact portion 41 ′ from moving toward the side close to the first wall 73 , that is, the two second stoppers 51 ′ are used to stop the two second contact portions 41 ′ from moving.

[0062] like Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, when the electrical connector 100 and the docking connector 100' are plugged in along the plugging direction, each of the first terminal components A is connected to the corresponding second terminal components B, and the arc-shaped guide portion 35' guides the abutting portion 7312, and the first terminal component A extends into the corresponding second shielding shell 3', that is, the first shielding shell 7 and the pair of first signal terminals 8 both extend into the second shielding shell 3'. In this way, the first outer wall 31' is located outside the first wall 73, and the second outer wall 32' is located outside the second wall 75. In addition, the abutting portion 7312 abuts against the inner wall surface of the first outer wall 31' along the thickness direction, and the abutting portion 7312 is offset toward one side of the first contact portion 81 by the abutting force of the first outer wall 31', that is, the abutting portion 7312 will be offset downward. At the same time, the first outer wall 31' will also shield the outside of the first avoidance space 732, thereby preventing external interference signals from entering the first terminal assembly A from the first avoidance space 732 and interfering with the first signal terminal 8 and the second signal terminal 4' that are connected to each other. Moreover, when the first shielding shell 7 extends into the second shielding shell 3', the two abutting elastic arms 741 of the two first side walls 74 will also abut against the second shielding shell 3', thereby making the first shielding shell 7 and the second shielding shell 3' have multiple abutting points, so that both the first shielding shell 7 and the second shielding shell 3' have a good grounding effect.

[0063] like Fig.11 and Fig.12As shown, when the electrical connector 100 and the docking connector 100' are plugged together along the plugging direction, the second contact portion 41' is located on the side of the first contact portion 81 away from the second avoidance space 33', that is, the second contact portion 41' is located below the first contact portion 81. Specifically, the first terminal assembly A extends into the corresponding second shielding shell 3', and the second head 413' and the second contact section 412' extend into the first shielding shell 7 away from the second fixing portion 42'. When viewed along the thickness direction, the second head 413' bends and extends toward the side close to the spring 731, and when viewed along the arrangement direction, the second head 413' and the abutting portion 7312 are staggered. The distance between the connecting portion 7311 and the second signal terminal 4' along the thickness direction is greater than the distance between the first signal terminal 8 and the second wall 75. One end of the second contact segment 412' away from the second fixing portion 42' is arranged opposite to the support portion 8112, and the second contact segment 412' abuts against the first contact segment 811. Specifically, the second contact segment 412' abuts against the support portion 8112 to form a contact point. Along the thickness direction (i.e., the up-down direction), the abutment point between the second contact segment 412' and the support portion 8112 overlaps with the first stopper 91, i.e., the abutment point between the second contact segment 412' and the support portion 8112 is located directly below the first stopper 91, and the second contact segment 412' and the support portion 8112 abutting against each other are located directly below the overlapping area of ​​the second wall 75 and the second outer wall 32'. In this way, the two first stoppers 91 can stop the support portion 8112 from moving toward the side close to the second wall 75, that is, the two first stoppers 91 can stop the support portion 8112 from moving upward, which not only allows the second contact segment 412' and the support portion 8112 to be stably docked, but also prevents the support portion 8112 from moving excessively upward and contacting the second wall 75 to cause a short circuit.

[0064] like Fig.11 and Fig.12As shown, when the electrical connector 100 and the docking connector 100' are plugged in along the plugging direction, the suspended portion 8113 is arranged opposite to the end of the second contact segment 412' close to the second fixing portion 42', and the suspended portion 8113 is located directly above the end of the second contact segment 412' close to the second fixing portion 42', and the second contact segment 412' abuts against the suspended portion 8113 to form a contact point. The abutment point between the suspended portion 8113 and the second contact segment 412' in the thickness direction (i.e., the up-down direction) overlaps with the second stopper 51', i.e., the abutment point between the suspended portion 8113 and the second contact segment 412' is located directly above the second stopper 51', and the suspended portion 8113 and the second contact segment 412' abutting against each other in the thickness direction are located directly above the overlapping area of ​​the first wall 73 and the first outer wall 31'. In this way, the two second stoppers 51' can stop the second contact portion 41' from moving toward the side close to the first wall 73, that is, the two second stoppers 51' can stop the two second contact portions 41' from moving downward, which not only allows the suspended portion 8113 and the second contact segment 412' to be stably docked, but also prevents the second contact segment 412' from moving excessively downward and contacting the first wall 73 to cause a short circuit.

[0065] like Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, when the electrical connector 100 and the docking connector 100' are plugged in along the plugging direction, the two first heads 812 are opposite to the second avoidance space 33' along the thickness direction, and the first heads 812 are bent toward the second avoidance space 33'. The projection of the fence 34' along the thickness direction is located between the projections of the concave edges of the two grooves 8111; thus, the two second avoidance spaces 33' can provide space for the two first heads 812, thereby preventing the two first heads 812 from contacting the second shielding shell 3', thereby causing the first signal terminal 8 and the second shielding shell 3' to short-circuit. Moreover, when observed along the thickness direction, the projection of the first head 812 overlaps with the projection of the second stopper 51' and the second avoidance space 33', thereby preventing the second contact portion 41' from moving due to the force exerted by the first head 812 on the second contact portion 41'.

[0066] like Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, when the electrical connector 100 and the docking connector 100' are plugged into each other along the plugging direction, the second head 413' is offset toward the spring piece 731 along the thickness direction by the abutting force of the first contact portion 81, and the two second heads 413' are arranged opposite to the first avoidance space 732 when viewed along the thickness direction, and the second heads 413' are bent toward the first avoidance space 732, so that the first avoidance space 732 can provide a place for the two second heads 413', and at the same time, the projection of the abutting portion 7312 is also located between the projections of the recessed edges of the two recessed portions 411' when viewed along the thickness direction, so as to avoid the abutting portion 7312 from being offset toward one side of the second head 413' by the abutting force of the first outer wall 31', so that the abutting portion 7312 is prevented from contacting the second head 413' and causing a short circuit. Moreover, when viewed along the thickness direction, the projection of the second head 413 ′ overlaps with the projections of the first stopper 91 and the first avoidance space 732 , so that the force exerted by the second head 413 ′ on the first contact portion 81 is resisted by the first stopper 91 , thereby preventing the first contact portion 81 from moving.

[0067] In summary, the electrical connector assembly 1000 of the present invention has the following beneficial effects:

[0068] (1) The first shielding shell 7 is provided with the elastic sheet 731, and the elastic sheet 731 has the abutting portion 7312. A pair of the second contact portions 41' are respectively provided with the recessed portions 411' along the arrangement direction on one side facing each other. The two recessed portions 411' are arranged opposite to each other, and the distance between the recessed edges of the two recessed portions 411' along the arrangement direction is greater than or equal to the width of the abutting portion 7312. When the electrical connector 100 and the docking connector 100' are plugged into each other along the plugging direction, the second contact portion 41' is located between the first contact portion 81 and the elastic sheet 731 along the thickness direction. When viewed from the thickness direction, the projection of the abutting portion 7312 is located between the projections of the recessed edges of the two recessed portions 411'. In this way, even as the plugging depth increases, the second contact portion 41' is located between the first contact portion 81 and the elastic sheet 731. The abutment portion 7312 is displaced toward the second contact portion 41' by the abutment force of the second shielding shell 3', and / or the second contact portion 41' is also displaced toward the second contact portion 41' by the abutment force of the first contact portion 81 at the same time. However, since the projection of the abutment portion 7312 is located between the projections of the recessed edges of the two recessed portions 411', the second contact portion 41' is always misaligned with the abutment portion 7312 in the thickness direction. Therefore, even if the abutment portion 7312 and / or the second contact portion 41' are displaced by force, the abutment portion 7312 and the second contact portion 41' will not contact each other due to being too close, thereby avoiding the second signal terminal 4' and the second shielding shell 3' from being electrically connected and short-circuited.

[0069] (2) Each of the first contact portions 81 has the supporting portion 8112 and the suspended portion 8113, and the first insulator 9 has two first stoppers 91. The two first stoppers 91 are respectively opposite to the two supporting portions 8112 along the thickness direction. Thus, the first stoppers 91 can not only stop the supporting portion 8112, thereby preventing the supporting portion 8112 from moving toward the side close to the second wall 75, thereby causing the first signal terminal 8 and the first shielding shell 7 to contact and short-circuit, but also because the first stoppers 91 are opposite to the supporting portion 8112, the medium around the supporting portion 8112 is plastic, thereby reducing the characteristic impedance of the supporting portion 8112 compared to the medium around the supporting portion 8112 being air; and the distance between the two supporting portions 8112 along the arrangement direction is greater than the distance between the two suspended portions. The distance between the two support portions 8112 and the support portion 8113 can increase the characteristic impedance of the support portion 8112, so that the support portion 8112 is affected by the first stopper 91, resulting in the lowered impedance of the support portion 8112 being increased, thereby ensuring that the characteristic impedance of the entire first signal terminal 8 changes more smoothly; and the distance between the two support portions 8112 along the arrangement direction is greater than the width of the abutment portion 7312, and when the electrical connector 100 is connected to the docking connector 100', the projection of the abutment portion 7312 observed along the thickness direction is located between the projections of the two support portions 8112, so that even if the abutment portion 7312 is moved toward one side of the first contact portion 81 by the abutting force of the first outer wall 31', the abutment portion 7312 will not contact and conduct with the first contact portion 81, thereby causing the first shielding shell 7 and the first signal terminal 8 to be short-circuited.

[0070] (3) Along the plugging direction, the groove 8111 is recessed from the first contact section 811 and extends to the first head 812. The second avoidance space 33' is two through holes spaced apart along the arrangement direction. The fence 34' is arranged between the two through holes along the arrangement direction. In this way, the fence 34' can increase the strength of the second shielding shell 3' at the second avoidance space 33'. When the electrical connector 100 and the docking connector 100' are connected to each other along the plugging direction, the two through holes are arranged opposite to the two first heads 812 along the thickness direction. When viewed along the thickness direction, the projection of the fence 34' is located between the projections of the edges of the two grooves 8111. In this way, even if the two first heads 812 are displaced upward by the abutting force of the second contact portion 41', the first head 812 and the second shielding shell 3' will not contact each other, thereby causing a short circuit between the first signal terminal 8 and the second shielding shell 3'.

[0071] (4) The spring piece 731 is tapered along the plug-in direction, and the spring piece 731 has the connecting portion 7311 and the abutting portion 7312 connected to each other, and the end of the connecting portion 7311 away from the abutting portion 7312 is connected to the first shielding shell 7, so that not only the spring piece 731 has better elasticity, but also the connection between the connecting portion 7311 and the first shielding shell 7 has a larger width, which can reduce the stress of the spring piece 731 concentrated on the connection between the connecting portion 7311 and the first shielding shell 7; when the electrical connector When the docking connector 100 is plugged into the docking connector 100' along the plugging direction, the second head 413' is offset toward the spring piece 731 along the thickness direction due to the abutting force of the first contact portion 81, and the two second head portions 413' are arranged opposite to the first avoidance space 732 when viewed along the thickness direction. In this way, even if the second head portion 413' is moved upward due to the abutting force of the first contact portion 81, the second head portion 413' will not contact the first shielding shell 7, thereby causing a short circuit between the second signal terminal 4' and the first shielding shell 7.

[0072] (5) The first wall 73 is provided on the first shielding body 71, and the second wall 75 is provided on the second shielding body 72. The first shielding body 71 extends forward beyond the second shielding body 72 along the plugging direction, and the second wall 75 is located between the positioning portion 742 and the first wall 73 in the thickness direction. Thus, when the first terminal assembly A is installed in the receiving groove 51, the first shielding body 71 is located on the inner side of the insulating module 5, and the second shielding body 72 is located on the outer side of the insulating module 5. This avoids the positioning portion 742 from interfering with the inner wall of the receiving groove 51 and thus wearing the insulating module 5 or causing a large gap in the assembly. In addition, the first terminal assembly A can be inserted into the receiving groove 51 more smoothly, so that the first shielding body 71 is close to the corresponding inner wall surface of the receiving groove 51, thereby facilitating the installation of the first terminal assembly A.

[0073] (6) The recessed portion 411' is recessed from the second contact section 412' and extends to the second head 413'. The recessed length of the recessed portion 411' along the plugging direction is less than the length of the second contact portion 41'. The recessed portion 411' can not only provide a space for the abutting portion 7312 of the spring sheet 731, thereby preventing the spring sheet 731 from short-circuiting with the second signal terminal 4', but also the existence of the recessed portion 411' will increase the impedance of the second contact portion 41' at the recessed portion 411'. However, since the recessed portion 411' is only recessed in the free section of the second contact portion 41' and not in the entire second contact portion 41', the recessed portion 411' will not have a significant impact on the characteristic impedance of the entire second contact portion 41', thereby ensuring that the impedance change of the entire second signal terminal 4' is smoother.

[0074] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
