[0001] The utility model relates to the technical field of conductive connection devices, and particularly relates to a connector. Background Art

[0002] With the improvement of signal transmission rate, high-speed connectors have higher and higher requirements for signal crosstalk resistance. The shielding structure of high-speed connectors is used to reduce crosstalk between different signal lines and achieve high-speed signal transmission. For example, a high-speed backplane connector socket disclosed in a Chinese invention patent with the authorization announcement number of CN116073172B, the socket board body thereof includes a base and a fixing clip. Between the base and the fixing clip, there are multiple alternately distributed wafers A, wafers B and wafer C. Shielding terminals are arranged on both sides of wafers A and wafers B, and a shielding sheet is arranged inside wafer C. A plurality of elastic pieces are arranged on the shielding sheet and are bent towards both sides respectively. The elastic pieces on both sides of the shielding sheet can be in contact with the adjacent shielding terminals on the left and right sides, and the shielding effect is better, reducing signal transmission loss.

[0032] A shielding conduction member is arranged at the crimping end of the connector of the present utility model. An avoidance through-hole and contact through-holes are arranged on the shielding conduction member. By avoiding the signal crimping portion of the transmission wafer through the avoidance through-hole and allowing the ground crimping portion to pass through the contact through-holes, the signal crimping portion and the ground crimping portion can be crimped to the corresponding printed circuit board. The contact portion of the ground crimping portion and the contact through-holes of the shielding conduction member are in interference fit to achieve fixed connection while enabling the ground crimping portion and the shielding conduction member to form electrical contact. Furthermore, the shielding conduction member is used to conduct the ground crimping portion of the transmission wafer and the ground crimping portion of the shielding wafer. The ground crimping portion of the transmission wafer and the ground crimping portion of the shielding wafer are press-fitted into the corresponding contact through-holes of the shielding conduction member to achieve the structure of shielding conduction, which has a relatively stable structure and is beneficial to contact reliability.

[0033] An embodiment of the connector of the present utility model:

[0034] As Figure 1 shown, the connector includes a connector housing 1, a transmission wafer 2, a shielding wafer 3, a shielding conduction member 4, and a fixing piece 5. A plurality of transmission wafers 2 are arranged side by side, and a shielding wafer 3 is sandwiched between every two transmission wafers 2. Each transmission wafer 2 and each shielding wafer 3 are installed on the connector housing 1 and are connected together by being clamped with the same fixing piece 5. The connector has a crimping end and a mating end. The crimping end is used to be crimped to the corresponding printed circuit board, and the mating end is used to be plugged with a mating connector. The transmission wafer 2 can transmit high-speed signals, and the shielding wafer 3 is used to enhance the shielding effect between two adjacent transmission wafers 2 and is suitable for electrical connectors with higher signal transmission rates. The shielding conduction member 4 is arranged at the crimping end of the connector. The shielding conduction member 4 can conduct the shielding structures of each transmission wafer 2 and shielding wafer 3 to achieve common grounding, and has a good shielding effect.

[0035] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5, Figure 6 , Figure 7 As shown in Figure 6 and Figure 7 , the transmission wafer 2 includes a first insulator 21, a first shielding sheet 22, and signal terminals. The signal terminals are trace terminals, and the signal terminals are arranged in pairs to form a differential pair. One end of the signal terminal is provided with a signal plugging structure, and the other end is provided with a signal crimping portion 24. The signal terminals are fixed on the first insulator 21. The first insulator 21 constitutes the insulator of the transmission wafer 2. On both sides in the thickness direction of the first insulator 21, first shielding sheets 22 are fixed. The first shielding sheet 22 is the shielding structure of the transmission wafer 2. The first shielding sheet 22 constitutes a side shielding sheet provided on the side of the transmission wafer 2. The first shielding sheet 22 is provided with a ground plugging structure and a first ground crimping portion 23. The first ground crimping portion 23 constitutes the ground crimping portion of the shielding wafer 3. The signal crimping portion 24 of the signal terminal and the first ground crimping portion 23 of the first shielding sheet 22 are arranged at the crimping end of the connector for crimping with a printed circuit board. The connector housing 1 is provided with a receiving cavity 11. After each transmission wafer 2 is mounted on the connector housing 1, the first insulator 21 is snap-fitted with the connector housing 1. The signal plugging structure of the signal terminal and the ground plugging structure of the first shielding sheet 22 extend into the corresponding receiving cavity 11. The receiving cavity 11 penetrates along the plugging direction of the connector for the insertion of the pins of the mating connector.

[0036] The shielding conduction member 4 is a plate body and can conduct electricity. The shielding conduction member 4 can be made of conductive plastic. At the position corresponding to the transmission wafer 2 on the shielding conduction member 4, an avoidance through hole 43 and a first contact through hole 41 are provided. The avoidance through holes 43 correspond to the signal terminals one by one. The avoidance through holes 43 allow the signal crimping portions 24 of the signal terminals of the transmission wafer 2 to pass through and avoid the signal crimping portions 24 so that the signal terminals do not contact the shielding conduction member 4. The avoidance through holes 43 allow the fish-eye structures of the signal crimping portions 24 to pass through for crimping with the printed circuit board.

[0037] The first contact through hole 41 constitutes the contact through hole on the shielding conduction member 4 corresponding to the first ground crimping portion 23. The first ground crimping portion 23 is a cantilever structure and extends based on the main body of the first shielding sheet 22 in the direction of crimping to the printed circuit board at the crimping end of the connector. The root of the first ground crimping portion 23 is connected to the main body of the first shielding sheet 22. The extending direction of the ground crimping portion is its length direction. The thickness direction of the ground crimping portion is the thickness direction of the first shielding sheet 22. The width direction of the ground crimping portion is perpendicular to the length direction and the thickness direction. The first contact through hole 41 allows the first ground crimping portion 23 to pass through. The first ground crimping portion 23 is provided with a contact portion that is in interference fit with the first contact through hole 41 so that the first ground crimping portions 23 of the respective transmission wafers 2 form a reliable conductive contact with the shielding conduction member 4.

[0038] There are multiple first grounding crimping portions 23 on the first shielding sheet 22, and the first grounding crimping portions 23 are arranged at intervals along the arrangement direction of each differential pair of the transmission wafer 2. The contact portion of the first grounding crimping portion 23 is provided with a first protrusion 231 and a second protrusion 232 for interference fit with the inner wall of the first contact through hole 41. The first grounding crimping portion 23 includes a fish-eye structure provided on one side of its contact portion away from its root. The fish-eye structure of the first grounding crimping portion 23 passes through the first contact through hole 41 to crimp the printed circuit board.

[0039] The first contact through hole 41 is adapted to the first grounding crimping portion 23. The width of the portion of the first grounding crimping portion 23 provided with the first protrusion 231 is greater than the width of the portion provided with the second protrusion 232. Correspondingly, the first contact through hole 41 is a stepped hole structure. The first contact through hole 41 has a large hole section with a larger size in the width direction of the first grounding crimping portion 23 and a small hole section with a smaller size in the width direction of the first grounding crimping portion 23. The small hole section is arranged on the outside. The first protrusion 231 is in interference fit with the inner wall of the small hole section of the first contact through hole 41, and the second protrusion 232 is in interference fit with the inner wall of the large hole section of the first contact through hole 41. Both the first protrusion 231 and the second protrusion 232 are forced-fit protrusions protruding from the side surfaces in the width direction of the contact portion of the first grounding crimping portion 23. By using the forced-fit protrusions to be in interference fit with the inner wall of the first contact through hole 41, the fit is reliable, and it is beneficial to reduce the scraping of the shielding conduction member 4 during forced fitting and reduce the generation of conductive plastic chips.

[0040] The first grounding crimping portion 23 is provided with a first guiding inclined surface 233 on the side of the first protrusion 231 close to the fish-eye structure. The first guiding inclined surface 233 can play a guiding role when the first grounding crimping portion 23 is inserted into the first contact through hole 41, and the existence of the inclined surface can also prevent this part from squeezing the inner wall of the first contact through hole 41 to generate conductive plastic chips. The first protrusion 231 is provided with a contact inclined surface that is in interference fit with the inner wall of the first contact through hole 41. The contact inclined surface is coplanar with the first guiding inclined surface 233, which is convenient for the first protrusion 231 to be pressed into the shielding conduction member 4, and the pressing process is smooth, which is beneficial to reducing the generation of conductive plastic chips.

[0041] The first protrusion 231 and the second protrusion 232 are spaced apart along the extending direction of the first ground crimping portion 23. The spaced-apart first protrusion 231 and second protrusion 232 are beneficial to enhancing the reliability of the interference fit between the first shielding sheet 22 and the shielding conduction member 4. One first protrusion 231 and an adjacent second protrusion 232 constitute two adjacent strong-fitting protrusions in the extending direction of the first ground crimping portion 23. The second protrusion 232 is close to the root of the cantilever structure, the first protrusion 231 is far from the root of the cantilever structure and close to the fish-eye structure, and the protrusion height of the second protrusion 232 is greater than that of the first protrusion 231. The second protrusion 232 with a greater protrusion height can achieve a more stable interference fit and make the height of the first protrusion 231 relatively low, which is beneficial to the gentle application of force during the interference assembly operation.

[0042] As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, the shielding wafer 3 includes a second insulator 31 and a second shielding sheet 32. The second shielding sheet 32 and the second insulator 31 are fixed together by integral injection molding. The second insulator 31 constitutes the insulator of the shielding wafer 3, and the second shielding sheet 32 constitutes the inner shielding sheet of the shielding wafer 3. The second shielding sheet 32 is provided with a second ground crimping portion 33 at the crimping end of the connector. There are multiple second ground crimping portions 33 on the second shielding sheet 32, and the second ground crimping portions 33 are spaced apart in the arrangement direction of each differential pair of the transmission wafer 2. The second ground crimping portion 33 is a cantilever structure and extends along the direction in which the main body of the second shielding sheet 32 is crimped to the printed circuit board at the crimping end of the connector. The root of the second ground crimping portion 33 is connected to the main body of the second shielding sheet 32. The shielding conduction member 4 is provided with a second contact through-hole 42 adapted to the second ground crimping portion 33. The second ground crimping portion 33 passes through the second contact through-hole 42, and the second ground crimping portion 33 is provided with a contact portion that has an interference fit with the second contact through-hole 42, so that the second ground crimping portions 33 of each shielding wafer 3 form a reliable electrical contact with the shielding conduction member 4. By using the shielding conduction member 4 to conduct the ground crimping portion of the transmission wafer 2 and the ground crimping portion of the shielding wafer 3, and the ground crimping portions of the transmission wafer 2 and the shielding wafer 3 are interference-fitted into the corresponding contact through-holes of the shielding conduction member 4 to achieve the shielding conduction structure, the structure is relatively stable and beneficial to the contact reliability.

[0043] The contact portion of the second ground crimping portion 33 is provided with a third protrusion 331 for interference-fitting with the hole wall of the second contact through-hole 42. The second ground crimping portion 33 includes a fish-eye structure provided on the side of its contact portion away from its root. Each second ground crimping portion 33 is provided with two fish-eye structures, and the fish-eye structures of the second ground crimping portion 33 pass through the second contact through-hole 42 to crimp the printed circuit board.

[0044] On both sides in the width direction of the contact portion of the second grounding crimping portion 33, third protrusions 331 are convexly provided. The third protrusions 331 constitute the forced-fitting protrusions on the second grounding crimping portion 33. On the side of the third protrusions 331 close to the fish-eye structure, the second grounding crimping portion 33 is provided with a second guiding inclined surface 332. The second guiding inclined surface 332 can play a guiding role when the second grounding crimping portion 33 is inserted into the second contact through-hole 42, and the existence of the inclined surface can also prevent the inner wall of the first contact through-hole 41 from being extruded to generate conductive plastic chips. On the third protrusions 331, contact inclined surfaces that are in interference fit with the hole wall of the second contact through-hole 42 are provided. The contact inclined surfaces and the corresponding second guiding inclined surfaces 332 are coplanar, which facilitates the pressing of the third protrusions 331 into the shielding conduction member 4, and the pressing process is smooth, which is beneficial to reducing the generation of conductive plastic chips.

[0045] The connector housing 1 is provided with an installation structure for installing the shielding wafer 3. The installation structure is a plug post 12. On the second insulator 31 of the shielding wafer 3, a slot 34 for inserting the plug post 12 is provided. The plug post 12 is in tight fit with the slot wall of the slot 34 to use the connector housing 1 to limit and fix the shielding wafer 3. The structure is simple and the operation is convenient. Moreover, both the transmission wafer 2 and the shielding wafer 3 are installed on the connector housing 1, which is beneficial to ensuring the installation position. The main body of the second shielding sheet 32 of the shielding wafer 3 is provided with a large-area hollow structure. The hollow structure includes vertically intersecting strip-shaped portions. The hollow structure is used for weight reduction and can save materials under the condition of meeting the shielding requirements.

[0046] In other embodiments, the grounding crimping portion can also make the width of its contact portion greater than the width of the contact through-hole, so that the side surfaces in the width direction of the contact portion are directly in interference fit with the hole wall of the contact through-hole. At this time, the forced-fitting protrusions are not separately provided.

[0047] In other embodiments, the inclination angles of the guiding inclined surface and the contact inclined surface on the forced-fitting protrusion can also be different.

[0048] In other embodiments, only the first protrusions can be provided on the first grounding crimping portion, and the second protrusions are no longer provided.

[0049] In other embodiments, the protrusion height of the first protrusions can also be the same as the protrusion height of the second protrusions.

[0050] In other embodiments, the first grounding crimping portion and the second grounding crimping portion can also be set in the same structural form. Correspondingly, the first contact through-hole matches the first grounding crimping portion, and the second contact through-hole matches the second grounding crimping portion.

[0051] In other embodiments, the second grounding crimping portion can also be provided with more than two forced-fitting protrusions in its overhanging direction.
