Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector for improving high-frequency operation. Background Technology

[0002] An existing electrical connector includes an insulating body, a terminal block, and multiple conductive terminals. The insulating body has a mating surface and a mounting surface disposed opposite each other along the mating direction, a insertion cavity recessed from the mating surface, and a mounting cavity recessed from the mounting surface. The insulating body also has multiple partitions distributed on both sides of the insertion cavity in the transverse direction. A signal groove is formed between two adjacent partitions on the same side of the insertion cavity. The longitudinal direction, transverse direction, and mating direction are mutually perpendicular to each other.

[0003] Each of the conductive terminals includes a contact portion, a conductive portion, and an intermediate portion connecting the contact portion and the conductive portion. The contact portion is exposed in the insertion cavity, and the conductive portion is exposed in the insulating body. The plurality of conductive terminals are arranged in two rows along the transverse direction, and each row of conductive terminals is arranged along the longitudinal direction. Each row of conductive terminals includes at least one signal pair and a plurality of ground terminals. The signal pair has adjacent ground terminals distributed on both sides in the longitudinal direction, and a partition is provided between the signal pair and the adjacent ground terminals. The intermediate portion of the signal pair includes a fixed section and an elastic section connected to each other. The fixed section is fixed to the terminal base, and the elastic section protrudes from the terminal base and is connected to the contact portion. The signal slot receives at least a portion of each of the two elastic sections of the signal pair.

[0004] The terminal block is housed in the mounting cavity. The terminal block has a reference plane on the side facing the mating surface in the mating direction. The reference plane is used to align a mating element inserted into the insertion cavity. The middle portion of the signal pair is usually longer than the contact portion and the conductive portion. Since the length of the conductive terminal is proportional to the inductance, the longer the conductive terminal, the greater the inductance. The greater the inductance, the greater the characteristic impedance. Therefore, the middle portion is often the location of high impedance. The fixed section of the signal pair, which is fixed to the terminal block, is encased in plastic, which increases the dielectric constant around the conductive terminal, thus increasing the capacitance and effectively reducing the characteristic impedance of that part. However, since the elastic section of the signal pair is exposed to air, and air has a low dielectric constant and low capacitance, the impedance of the elastic section of the signal pair is relatively high. Overall, the impedance of the middle portion is largely mismatched, which will cause reflection loss when the signal is input, affecting the signal output and hindering the signal integrity of the electrical connector signal transmission.

[0005] Therefore, it is necessary to design a new electrical connector to overcome the above problems. Summary of the Invention

[0006] To address the problems of the prior art, the present invention aims to provide a new electrical connector that, by providing multiple insulating protrusions on the terminal block, shields a portion of each of the two elastic segments of the signal pair in the lateral direction, thereby reducing the air medium around the elastic segments of the signal pair, thus adjusting the impedance and improving high frequency performance.

[0007] To achieve the above objectives, the present invention provides an electrical connector, comprising: an insulating body having a mating surface and a mounting surface disposed opposite each other along a mating direction, a insertion cavity recessed from the mating surface, and a mounting cavity recessed from the mounting surface; the insulating body further having a plurality of partitions distributed on both sides of the insertion cavity in a transverse direction, a signal groove being formed between two adjacent partitions on the same side of the insertion cavity, the longitudinal direction, the transverse direction, and the mating direction being mutually perpendicular; a terminal base received in the mounting cavity; and a plurality of conductive terminals, each conductive terminal including a contact portion, a conductive portion, and an intermediate portion connecting the contact portion and the conductive portion, the contact portion being exposed in the insertion cavity, the conductive portion being exposed in the insulating body, the plurality of conductive terminals being arranged in two rows along the transverse direction, each row of conductive terminals being arranged along the longitudinal direction, each row of conductive terminals including at least one signal pair and a plurality of ground terminals, the signal pair having adjacent ground terminals distributed on both sides in the longitudinal direction, and the signal pair... A partition is provided between the signal pair and the adjacent grounding terminal. The middle portion of the signal pair includes a fixed section and an elastic section connected to each other. The fixed section is fixed to the terminal base, and the elastic section protrudes from the terminal base and connects to the contact portion. The signal slot receives at least a portion of each of the two elastic sections of the signal pair. The terminal base has a plurality of insulating protrusions, which are received in the signal slot. The insulating protrusions are located in the lateral direction between the plug cavity and the corresponding signal pair, and in the lateral direction, the insulating protrusions shield at least a portion of each of the two elastic sections of the corresponding signal pair. The insulating body also has a plurality of separating ribs, which protrude from the signal slot. A separating rib is provided between the two elastic sections of the signal pair. With respect to the same side of the plug cavity, the separating rib is located in the lateral direction away from the partition relative to the plug cavity, and the dimension of the separating rib in the longitudinal direction is smaller than the dimension of the partition in the longitudinal direction.

[0008] Furthermore, the insulating body also has a plurality of protrusions protruding toward the signal groove. The protrusions are closer to the mating surface than the separating ribs and are spaced apart from the corresponding separating ribs. The size of the protrusions in the longitudinal direction is larger than the size of the separating ribs in the longitudinal direction. The conductive terminal in the signal pair also has a tail that connects to the contact portion. The two tails of the signal pair are separated in the longitudinal direction by the corresponding protrusions.

[0009] Furthermore, the partition rib extends in the mating direction and has a connecting surface and a first side surface and a second side surface disposed opposite each other in the longitudinal direction. The first side surface and the second side surface extend in the transverse direction toward the side close to the insertion cavity and are respectively connected to the connecting surface.

[0010] Furthermore, along the docking direction, the end of the partition rib furthest from the docking surface is defined as the second distal end, and the end of the partition rib closest to the docking surface is defined as the second proximal end. The second proximal end is positioned closer to the insertion cavity in the lateral direction than the second distal end.

[0011] Furthermore, along the docking direction, the end of the partition that is far from the docking surface is defined as the first far end, and the end of the partition rib that is far from the docking surface is defined as the second far end. The second far end is positioned closer to the docking surface in the docking direction than the first far end.

[0012] Furthermore, the terminal block has an end face facing the mating surface in the mating direction, and the elastic segment protrudes relative to the end face in the mating direction toward the side closer to the mating surface. Along the mating direction, the end of the separating rib away from the mating surface is defined as the second distal end, which is closer to the mating surface in the mating direction than the end face.

[0013] Furthermore, the distance between the second distal end and the end face in the mating direction is greater than the dimension of the partition rib in the mating direction.

[0014] Furthermore, the insulating protrusion extends towards the side closer to the mating surface in the mating direction. Along the mating direction, the end of the separating rib away from the mating surface is defined as the second distal end. The insulating protrusion is disposed closer to the mating surface than the second distal end. The insulating protrusion shields the second distal end in the lateral direction.

[0015] Furthermore, each of the elastic segments includes a first segment and a second segment connected to each other. The first segment is connected to the corresponding contact portion, and the second segment is connected to the corresponding fixed segment. The distance between the two first segments of the signal pair in the longitudinal direction is less than the distance between the two second segments of the signal pair in the longitudinal direction. The separating rib is located between the two first segments of the signal pair in the longitudinal direction.

[0016] Furthermore, the terminal block includes two insulating seats and an insulating plug located between the two insulating seats in the lateral direction. Each insulating seat is respectively embedded in a row of conductive terminals, and a plurality of insulating protrusions are provided on the insulating plug.

[0017] Furthermore, the two insulating seats and the insulating plug are connected by assembly, and the partition has a stop surface facing the mounting surface, the stop surface being used to stop one of the two insulating seats and the insulating plug.

[0018] Furthermore, the insulating body has two bosses, each boss having a reference plane. The insulating plug also includes a main body and at least one rib connected to the main body. The rib is closer to the mating surface than the main body in the mating direction. Both the reference plane and the rib are exposed in the insertion cavity in the mating direction. The rib is located between the two bosses in the longitudinal direction, and the reference plane is closer to the mating surface than the rib in the mating direction. The reference plane is used to align a mating element inserted into the insertion cavity.

[0019] Furthermore, the insulating body is provided with multiple snap-fit ​​slots, which are located on both sides of the mounting cavity in the lateral direction. The snap-fit ​​slots penetrate the insulating body in the lateral direction towards the side near the mounting cavity. Each insulating seat is provided with multiple locking blocks, which are received in the corresponding snap-fit ​​slots and engaged with the snap-fit ​​slots to fix the insulating seat to the insulating body. Multiple insulating protrusions are arranged in two rows in the lateral direction, which are located on both sides of the insertion cavity in the lateral direction. Each insulating protrusion has a stop block protruding on the side of the lateral direction away from the insertion cavity. The stop block is engaged with one of the two insulating seats in the mating direction towards the mating surface.

[0020] Furthermore, the elastic segment is bent and extended in the lateral direction relative to the fixed segment toward the side close to the insertion cavity. The stop is located in the lateral direction between the corresponding fixed segment and the corresponding contact portion. The insulating protrusion has a mating surface on the side facing the elastic segment. A portion of the mating surface extends on the stop. The shape of the mating surface is adapted to fit the elastic segment.

[0021] Furthermore, it includes a conductive plastic, which is fixedly connected to the insulating plug. Each of the two insulating seats has at least one mounting groove on one side facing each other in the lateral direction. The middle portion of the grounding terminal is exposed in the mounting groove. The conductive plastic includes a base and a plurality of protrusions connected to the base. The protrusions are positioned closer to the mating surface than the base in the mating direction. The plurality of protrusions are arranged in two rows in the lateral direction. The protrusions extend into the corresponding mounting groove in the lateral direction and are correspondingly positioned with the grounding terminal, thereby electrically connecting the conductive plastic to the grounding terminal.

[0022] Compared with the prior art, the present invention has the following beneficial effects: By providing the signal slot between two adjacent partitions on the same side of the insertion cavity, and providing a plurality of insulating protrusions on the terminal block, the insulating protrusions are received in the signal slots and positioned in the lateral direction between the insertion cavity and the signal pair. The insulating protrusions shield at least a portion of each of the two elastic segments corresponding to the signal pair in the lateral direction, thereby reducing the air around the two elastic segments of the signal pair. Furthermore, the insulating protrusions shield the side of the signal pair facing the insertion cavity in the lateral direction, increasing the dielectric constant around the two elastic segments of the signal pair, thereby increasing the capacitance of the two elastic segments of the signal pair, reducing the characteristic impedance, and making the impedance of the signal pair more matched, thereby improving high frequency performance.

These three directions are perpendicular to each other. The horizontal direction described herein is the front-to-back direction, the vertical direction is the left-to-right direction, and the docking direction is the up-and-down direction. Of course, in other embodiments, the horizontal direction, vertical direction, and docking direction can be selected from the front-to-back direction, the left-to-right direction, and the up-and-down direction as needed, as long as the three directions are perpendicular to each other.

[0027] The electrical connector 100 of the present invention provides a mating element 200 for mating in a mating direction and is mounted on a circuit board 300 in the mating direction.

[0028] like Figures 1 to 13 As shown, this is a first embodiment of the electrical connector 100 of the present invention. Figures 14 to 16 The image shows a second embodiment of the electrical connector 100 of the present invention.

[0029] like Figure 2 and Figure 15 As shown, in either of the two embodiments described above, the electrical connector 100 includes an insulating body 1, a terminal base 2 mounted on the insulating body 1, and a plurality of conductive terminals 3 disposed on the insulating body 1. The plurality of conductive terminals 3 are all fixed to the terminal base 2, and are arranged in two rows in the transverse direction, with each row of conductive terminals 3 arranged in the longitudinal direction. In other embodiments, the plurality of conductive terminals 3 may be partially fixed to the terminal base 2 and partially fixed to the insulating body 1.

[0030] like Figure 2 and Figure 15 As shown, in either of the two embodiments described above, the insulating body 1 is integrally molded from plastic material and has a mating surface 10 and a mounting surface 11 disposed opposite to each other along the mating direction, a insertion cavity 12 recessed from the mating surface 10, and a mounting cavity 13 recessed from the mounting surface 11 (see reference). Figure 4 and Figure 17 The insertion cavity 12 is used for insertion of the docking element 200, which is an electronic card (see reference). Figure 1 and Figure 14The two rows of conductive terminals 3 are located on both sides of the insertion cavity 12 in the lateral direction. In other embodiments, the mating element 200 may be a cable connector or other component structure.

[0031] like Figure 4 and Figure 17 As shown, in either of the two embodiments described above, the insulating body 1 further includes a plurality of partitions 14, a plurality of signal slots 15, a plurality of grounding slots 16, a plurality of partition ribs 17, and a plurality of protrusions 18.

[0032] like Figure 4 and Figure 17 As shown, in either of the two embodiments described above, a plurality of partitions 14 are located on both sides of the insertion cavity 12, that is, the plurality of partitions 14 are arranged in two rows in the lateral direction (see reference). Figure 8 and Figure 19 Each row of partitions 14 is arranged longitudinally. A signal slot 15 or a grounding slot 16 is formed between two adjacent partitions 14 on the same side of the insertion cavity 12. Specifically, the signal slots 15 and grounding slots 16 on the same side of the insertion cavity 12 are arranged alternately. That is, a signal slot 15 is formed between one partition 14 and a partition 14 on the adjacent side, and a grounding slot 16 is formed between one partition 14 and a partition 14 on the adjacent other side. Multiple signal slots 15 are correspondingly provided with multiple partition ribs 17. That is, each signal slot 15 is provided with a partition rib 17. The partition rib 17 extends longitudinally along the docking direction and protrudes from the corresponding signal slot 15 in the transverse direction. Multiple protrusions 18 are arranged one-to-one with multiple partition ribs 17 in the mating direction. The protrusions 18 protrude toward the corresponding signal grooves 15. The protrusions 18 are closer to the mating surface 10 than the partition ribs 17 and are spaced apart from the corresponding partition ribs 17. The dimension of the protrusions 18 in the longitudinal direction is larger than the dimension of the partition ribs 17 in the longitudinal direction (see reference). Figure 10 and Figure 25 ).

[0033] like Figure 8 and Figure 22 As shown, in either of the two embodiments described above, with respect to the same side of the insertion cavity 12, the partition rib 17 is disposed away from the insertion cavity 12 in the lateral direction relative to the partition 14, and the dimension of the partition rib 17 in the longitudinal direction is smaller than the dimension of the partition 14 in the longitudinal direction (see reference). Figure 10 and Figure 26 That is, the dividing rib 17 is narrower than the partition 14 in the longitudinal direction.

[0034] like Figure 4 and Figure 17 As shown, in either of the two embodiments described above, each of the partitions 14 has a first distal end 141 and a first proximal end 142 disposed opposite to each other along the docking direction. Along the docking direction, the end of the partition 14 furthest from the docking surface 10 is defined as the first distal end 141, and the end of the partition 14 closest to the docking surface 10 is defined as the first proximal end 142.

[0035] like Figure 4 and Figure 18 As shown, in either of the two embodiments described above, each of the partition ribs 17 has a second distal end 171 and a second proximal end 172 disposed opposite to each other along the mating direction. Along the mating direction, the end of the partition rib 17 furthest from the mating surface 10 is defined as the second distal end 171, and the end of the partition rib 17 closest to the mating surface 10 is defined as the second proximal end 172. The second proximal end 172 is disposed closer to the insertion cavity 12 in the transverse direction than the second distal end 171 (see reference). Figure 8 and Figure 22 ).

[0036] like Figure 7 , Figure 15 and Figure 23 As shown, in either of the two embodiments described above, the insulating body 1 also has a plurality of snap-fit ​​grooves Q arranged longitudinally on both sides of the insertion cavity 12 in the lateral direction. The plurality of snap-fit ​​grooves Q are located on both sides of the mounting cavity 13 in the lateral direction, and the snap-fit ​​grooves Q penetrate the insulating body 1 in the lateral direction.

[0037] like Figure 7 and Figure 22 As shown, in either of the two embodiments described above, the terminal block 2 includes two insulating seats 21 and an insulating plug 22 located between the two insulating seats 21 in the transverse direction. The two insulating seats 21 and the insulating plug 22 are all assembled from one side of the mounting surface 11 and housed in the mounting cavity 13. Each insulating seat 21 is respectively embedded with a row of conductive terminals 3 (see reference). Figure 3 and Figure 15 ).

[0038] like Figure 3 and Figure 7 , Figure 15 and Figure 23As shown, in either of the two embodiments described above, each insulating base 21 has an end face 211 and a plurality of locking blocks 212. The end face 211 is disposed on the side facing the mating surface 10 in the mating direction. The plurality of locking blocks 212 are received one-to-one in the plurality of locking slots Q and are engaged with the locking slots Q to fix the insulating base 21 to the insulating body 1.

[0039] like Figure 3 and Figure 15 As shown, in either of the two embodiments described above, the insulating plug 22 is integrally molded from plastic material. The insulating plug 22 has a main body 221 and a plurality of insulating protrusions 222 connecting the main body 221. The main body 221 is sandwiched between two insulating seats 21 and housed in the mounting cavity 13. The insulating protrusions 222 extend from the main body 221 along the mating direction and toward the mating surface 11. The plurality of insulating protrusions 222 protrude into the plurality of signal slots 15 one-to-one, and the insulating protrusions 222 do not protrude into the insertion cavity 12. Each insulating protrusion 222 is provided with a stop 2221 that protrudes from the main body in the lateral direction. The insulating protrusions 222 are arranged in two rows in the transverse direction. The two rows of insulating protrusions 222 are located on both sides of the insertion cavity 12 in the transverse direction. Each row of insulating protrusions 222 is arranged in the longitudinal direction. The stop block 2221 is arranged closer to the mating surface 10 than the end face 211 in the mating direction, and the stop block 2221 is engaged with a corresponding insulating seat 21 on the side closer to the mating surface 10, that is, the stop block 2221 is engaged with the corresponding end face 211. In this way, the insulating plug 22 can be fixed to the insulating body 1 by the insulating seat 21. Each insulating protrusion 222 has a mating surface 2222, and a part of the mating surface 2222 extends on the corresponding stop block 2221 (see reference). Figure 6 and Figure 22 ).

[0040] like Figure 6 and Figure 22 As shown, in either of the two embodiments described above, the insulating protrusion 222 is closer to the mating surface 10 and received in the signal slot 15 than the second distal end 171, and the insulating protrusion 222 shields the second distal end 171 in the lateral direction (see reference). Figure 10 and Figure 25 ).

[0041] like Figure 10 and Figure 24As shown, in either of the two embodiments described above, each row of conductive terminals 3 includes multiple signal pairs 3S and multiple ground terminals 3G. The signal pairs 3S have adjacent ground terminals 3G distributed on both sides in the longitudinal direction. The signal pairs 3S are used to transmit differential signals. In other embodiments, the number of signal pairs 3S in each row of conductive terminals 3 can be set as needed; it can be one, two, or more.

[0042] like Figure 6 and Figure 23 As shown, in either of the two embodiments described above, each conductive terminal 3 includes a contact portion 31, a conductive portion 32, an intermediate portion 33 connecting the contact portion 31 and the conductive portion 32, and a tail portion 34 connecting the contact portion 31. The contact portion 31 is exposed in the insertion cavity 12 in the lateral direction, and the conductive portion 32 is exposed in the mounting cavity 13.

[0043] like Figure 6 and Figure 23 As shown, in either of the two embodiments described above, the middle portion 33 of each conductive terminal 3 includes a fixed section 331 and an elastic section 332 connected to each other. The elastic section 332 is connected between the fixed section 331 and the contact portion 31. The fixed section 331 is fixed to the corresponding insulating seat 21. The elastic section 332 is bent and extended in the lateral direction relative to the fixed section 331 toward the side close to the insertion cavity 12. The elastic section 332 protrudes in the mating direction toward the side close to the mating surface 10 relative to the end face 211, that is, the elastic section 332 protrudes relative to the end face 211. The conductive portion 32 protrudes from the side away from the end face 211 to the corresponding insulating seat 21. The stop block 2221 is located in the lateral direction between the corresponding fixed section 331 and the corresponding contact portion 31.

[0044] like Figure 10 and Figure 25 As shown, in either of the two embodiments described above, the signal pair 3S is housed in the signal slot 15, and the ground terminal 3G is housed in the ground slot 16. Thus, a partition 14 is provided between the signal pair 3S and the adjacent ground terminal 3G. Specifically, the signal slot 15 houses at least a portion of each of the two elastic segments 332 of the signal pair 3S, and a separating rib 17 is provided between the two elastic segments 332 of the signal pair 3S.

[0045] like Figure 7 and Figure 22As shown, in either of the two embodiments described above, the insulating protrusion 222 is located in the lateral direction between the insertion cavity 12 and the elastic segment 332 of the corresponding signal pair 3S. That is, the insulating protrusion 222 shields at least a portion of each of the two elastic segments 332 of the corresponding signal pair 3S in the lateral direction. The mating surface 2222 is disposed facing the side facing the elastic segment 332 of the corresponding signal pair 3S. The shape of the mating surface 2222 is adapted to fit the elastic segment 332 of the corresponding signal pair 3S, so that the distance between the elastic segment 332 of the signal pair 3S and the mating surface 2222 in the lateral direction is relatively uniform overall, which is beneficial for adjusting the characteristic impedance. The two tails 34 of the signal pair 3S are separated in the longitudinal direction by the corresponding protrusion 18.

[0046] like Figures 1 to 13 The image shows a first embodiment of the electrical connector 100 of the present invention.

[0047] like Figure 8 As shown, in this embodiment, the two insulating seats 21 and the insulating plug 22 are fixedly connected and assembled together in the mounting cavity 13. The first distal end 141 also has a stop surface 1411 facing the mounting surface 11. The stop surface 1411 blocks the corresponding terminal seat 2 on the side facing the mounting surface 11 to prevent the corresponding terminal seat 2 from excessively displacing on the side facing the mating surface 10. Specifically, the stop surface 1411 is used to block one of the two insulating seats 21 and the insulating plug 22. The second distal end 171 only blocks the corresponding insulating seat 21 on the side facing the mounting surface 11, and does not block the insulating plug 22.

[0048] like Figure 11 and Figure 12 As shown, the insulating body 1 also has two protrusions 19 spaced apart in the longitudinal direction. The protrusions 19 extend from the mounting surface 11 toward the mating surface 10 to the insertion cavity 12. In the transverse direction, the protrusions 19 are located between the two rows of partitions 14. Each protrusion 19 has a reference plane 191. The reference plane 191 is disposed facing the mating surface 10 in the mating direction and exposed in the insertion cavity 12 for aligning the mating element 200 inserted into the insertion cavity 12.

[0049] like Figure 9 , Figure 10 and Figure 13As shown, the insulating plug 22 also has a plurality of protruding ribs 223 connecting the main body 221. The protruding ribs 223 are disposed facing the mating surface 10 in the mating direction and exposed in the insertion cavity 12. The protruding ribs 223 are located between the two bosses 19 in the longitudinal direction. The reference plane 191 is disposed closer to the mating surface 10 in the mating direction than the protruding ribs 223. There is a gap T between the reference plane 191 and the protruding ribs 223 in the mating direction. The protruding ribs 223 are closer to the mating surface 10 in the mating direction than the main body 221, providing a buffer when the mating element 200 is abnormally inserted into the insertion cavity 12, preventing the insulating plug 22 from being damaged by excessive force during abnormal insertion and removal, and thus damaging the conductive terminal 3.

[0050] like Figures 14 to 26 The image shows a second embodiment of the electrical connector 100 of the present invention.

[0051] like Figure 17 , Figure 24 and Figure 26 As shown, the second distal end 171 is closer to the mating surface 10 in the mating direction than the end face 211 and the first distal end 141, and the distance between the second distal end 171 and the end face 211 in the mating direction is greater than the size of the partition rib 17 in the mating direction.

[0052] like Figure 26 As shown, the elastic segment 332 of the signal pair 3S includes a first segment 3321 and a second segment 3322 connected to each other. The first segment 3321 is connected to the corresponding contact portion 31, and the second segment 3322 is connected to the corresponding fixed segment 331. The distance W1 between the two first segments 3321 of the signal pair 3S in the longitudinal direction is less than the distance W2 between the two second segments 3322 of the signal pair 3S in the longitudinal direction. The separating rib 17 is located between the two first segments 3321 of the signal pair 3S in the longitudinal direction.

[0053] like Figures 18 to 20 As shown, each of the partition ribs 17 also has a connecting surface 175 and a first side surface 173 and a second side surface 174 disposed opposite each other in the longitudinal direction. The first side surface 173 and the second side surface 174 extend towards the side closer to the insertion cavity 12 in the transverse direction and are respectively connected to the connecting surface 175.

[0054] like Figure 15 , Figure 16 and Figure 23As shown, each of the two insulating seats 21 has a plurality of mounting slots 213 on one side facing each other in the lateral direction. Each mounting slot 213 extends downward through the corresponding insulating seat 21, and the middle part 33 of the grounding terminal 3G is exposed in the corresponding mounting slot 213.

[0055] like Figure 15 As shown, the electrical connector 100 also includes a conductive plastic 4, which includes a base 41 and a plurality of protrusions 42 connecting the base 41, the plurality of protrusions 42 being arranged in two rows in the transverse direction.

[0056] like Figure 23 As shown, the conductive plastic 4 is fixedly connected to the insulating plug 22. The protrusion 42 is positioned closer to the mating surface 10 than the base 41 in the mating direction. The protrusion 42 extends into the corresponding mounting groove 213 in the transverse direction and is positioned corresponding to the grounding terminal 3G, thereby electrically connecting the conductive plastic 4 to the grounding terminal 3G. Specifically, the protrusion 42 contacts the corresponding grounding terminal 3G. Of course, in other embodiments, there is a relatively small gap between the protrusion 42 and the corresponding grounding terminal 3G, but electrical conduction can still be achieved.

[0057] like Figure 12 , Figure 22 and Figure 23 As shown, the assembly method of the electrical connector 100 in this embodiment is as follows: First, two rows of conductive terminals 3 are molded onto two insulating seats 21 to form two molded parts. The two molded parts are assembled from bottom to top into the mounting cavity 13. The molded parts are engaged with multiple latching blocks 212 of the insulating seat 21 into multiple snap-fit ​​slots Q of the insulating body 1, thereby fixing the insulating seat 21 to the insulating body 1. Then, the conductive plastic 4 is installed into the mounting cavity 13 from one side of the mounting surface 11. The conductive plastic 4 is... Multiple protrusions 42 extend into corresponding mounting grooves 213, thereby confining them between the two insulating seats 21. Finally, the insulating plug 22 is assembled into the mounting cavity 13 from one side of the mounting surface 11. The stop block 2221 is located on the side of the end face 211 near the mating surface 10 and engages with the end face 211, thereby preventing the insulating plug 22 from detaching downward from the insulating body 1. The main body 221 supports the base 41 to prevent the conductive plastic 4 from detaching downward from the mounting cavity 13.

[0058] The electrical connector of the present invention also has the following beneficial effects: 1. By providing a signal slot 15 between two adjacent partitions 14 on the same side of the insertion cavity 12, and providing a plurality of insulating protrusions 222 on the terminal block 2, the insulating protrusions 222 are received in the signal slot 15, and the insulating protrusions 222 are arranged in the transverse direction between the insertion cavity 12 and the signal pair 3S. The insulating protrusions 222 shield at least a portion of each of the two elastic segments 332 corresponding to the signal pair 3S in the transverse direction, thereby reducing the air around the two elastic segments 332 of the signal pair 3S. Furthermore, the insulating protrusions 222 shield the side facing the insertion cavity 12 in the transverse direction, thereby increasing the dielectric constant around the two elastic segments 332 of the signal pair 3S, thereby increasing the capacitance of the two elastic segments 332 of the signal pair 3S, reducing the characteristic impedance, and making the impedance of the signal pair 3S tend to match, thereby improving high frequency.

[0059] 2. By providing the separating rib 17 between the two elastic segments 332 of the signal pair 3S, the air around the two elastic segments 332 is reduced, and the plastic content between the two elastic segments 332 of the signal pair 3S is increased, thereby increasing the dielectric constant around the two elastic segments 332 of the signal pair 3S, increasing the capacitance, and reducing the impedance, so that the impedance of the signal pair 3S tends to match, thereby improving the high frequency. Since the interval between the signal pairs 3S is small, the dimension of the separating rib 17 in the longitudinal direction is set to be smaller than the dimension of the partition 14 in the longitudinal direction to avoid interference with the signal pair 3S and affect the performance of the electrical connector 100. The separating rib 17 is far away from the insertion cavity 12 in the transverse direction relative to the partition 14, and the dimension of the separating rib 17 in the transverse direction is smaller than the dimension of the partition 14 in the transverse direction, which facilitates the molding of the separating rib 17 in the process.

[0060] 3. The first side surface 173 and the second side surface 174 are inclined and extended towards the side of the insertion cavity 12 in the lateral direction and connected to the connecting surface 175 respectively. That is, the first side surface 173 and the second side surface 174 are inclined guiding slopes. The partition rib 17 is wider as it is closer to the outside of the insulating body 1 in the lateral direction. This allows the elastic segment 332 of the signal pair 3S to be guided when it moves away from the insertion cavity 12 in the lateral direction under the external force of the docking element 200, thus preventing the elastic segment 332 of the signal pair 3S from getting stuck.

[0061] 4. The insulating protrusion 222 is located closer to the mating surface 10 than the second distal end 171. The insulating protrusion 222 shields the second distal end 171 in the lateral direction, so that in the longitudinal direction, the parts of the two elastic segments 332 of the signal pair 3S that are not shielded by the separating rib 17 can be shielded by the insulating protrusion 222 in the lateral direction. This ensures that at least a portion of the two elastic segments 332 of the signal pair 3S are covered by plastic at different angles in different parts of their extension direction, thereby adjusting the overall impedance of the two elastic segments 332 of the signal pair 3S.

[0062] 5. The distance between the two first segments 3321 of the signal pair 3S in the longitudinal direction is less than the distance between the two second segments 3322 of the signal pair 3S in the longitudinal direction. The separating rib 17 is located between the two first segments 3321 of the signal pair 3S in the longitudinal direction. When the contact portion 31 of the signal pair 3S is displaced by the external force of the docking element 200, the position of the two elastic segments 332 in the signal pair 3S is effectively restricted, preventing the two first segments 3321 of the signal pair 3S from short-circuiting due to being too close to each other.

[0063] 6. By providing a stop surface 1411 facing the mounting surface 11 on the partition 14, the stop surface 1411 blocks one of the two insulating seats 21 and the insulating plug 22, preventing one of the two insulating seats 21 and the insulating plug 22 from excessively displacing towards the mating surface 10.

[0064] 7. By providing two protrusions 19 on the insulating body 1 and a rib 223 located between the two protrusions 19 in the longitudinal direction on the insulating plug 22, and by providing the reference plane 191 closer to the mating surface 10 in the mating direction than the rib 223, the mating element 200 can be correctly inserted into the bottom of the insertion cavity 12 with the reference plane 191 as the reference. The rib 223 is closer to the mating surface 10 in the mating direction than the main body 221, so that when the mating element 200 is inserted into the insertion cavity 12 abnormally (with greater force), the rib 223 can play a buffering role to prevent the conductive terminal 3 from being damaged and thus affecting the performance of the electrical connector 100.

[0065] 8. A stop block 2221 is provided on the side of the insulating protrusion 222 that is away from the insertion cavity 12 in the transverse direction. The stop block 2221 is engaged in the mating direction with one of the two insulating seats 21 on the side closer to the mating surface 10, thereby preventing the insulating plug 22 from detaching from the insulating body 1 on the side facing the mounting surface 11.

[0066] 9. The insulating protrusion 222 has a mating surface 2222 on the side facing the elastic segment 332. A portion of the mating surface 2222 extends on the stop block 2221. The shape of the mating surface 2222 is adapted to fit the elastic segment 332, so that the distance between the elastic segment 332 and the mating surface 2222 in the lateral direction is relatively uniform overall, which is beneficial for adjusting the characteristic impedance.

[0067] 10. By providing a plurality of protrusions 42 on the conductive plastic 4 that are closer to the mating surface 10 than the substrate 41 in the mating direction, the protrusions 42 extend into the corresponding mounting grooves 213 in the transverse direction and are correspondingly provided with the grounding terminal 3G, and the conductive plastic 4 is electrically connected to the grounding terminal 3G, so that the conductive plastic 4 can be located between the two corresponding insulating seats 21 in the transverse and longitudinal directions. The conductive plastic 4 and the grounding terminal 3G are correctly aligned, and the corresponding arrangement of the two can shorten the return current path of grounding and reduce resonance.

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.
