The transmission structure, i.e. the terminal module, includes a first signal lead module, a second signal lead module, a first holding frame, and a second holding frame. The signal lead module is installed on the corresponding holding frame. The first holding frame and the second holding frame are mutually buckled. The first signal lead module and the second signal lead module are arranged in pairs in the thickness direction of the transmission structure, forming a differential pair for transmitting differential signals. The two signal lead modules in one differential pair are coupled by the wide side. The transmission structure has at least two differential transmission paths. One pair of signal lead modules in each differential transmission path has the same electrical transmission distance, which is beneficial to improving the differential signal transmission quality.

DETAILED DESCRIPTION

[0040] The basic concept of the terminal module of the high-speed connector of the utility model is to set the shielding wall extending between two differential pairs on the shielding sheet to form shielding between the adjacent two differential pairs, improve the shielding effect, and further improve the transmission rate of the connector.

[0041] The utility model will be specifically explained in combination with specific embodiments.

[0042] Embodiments of the terminal module of the high-speed connector of the utility model:

[0043] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The terminal module of the high-speed connector includes a first module unit 11, a second module unit 12, and a first shielding sheet 21 and a second shielding sheet 22. The first module unit 11 and the second module unit 12 are mutually opposite to form a module main body of the terminal module. The module main body includes an insulator and each differential pair 16 fixed in the insulator. There are multiple differential pairs 16, and each differential pair 16 is arranged side by side. The differential pair 16 includes two signal terminals 13 arranged in pairs. The signal terminal 13 is a wiring terminal, and the wiring direction is the extension direction of the length thereof. The first shielding sheet 21 and the second shielding sheet 22 are shielding sheets of the terminal module. The shielding sheets are installed on the side of the insulator, and the corresponding shielding sheets can play a shielding role on one side of each differential pair 16.

[0044] In order to improve the shielding effect to adapt to the transmission requirement of a higher speed, a shielding structure is arranged between the differential pairs 16 of the terminal module and the differential pairs 16. Specifically, the shielding sheet includes a main sheet body and a shielding wall protruding from the main sheet body to the side where the differential pairs 16 are located. The shielding wall is a conductive structure and extends along the wiring direction of the signal terminal 13 of the differential pair 16. The insulator is provided with an avoidance slot for the shielding wall to avoid the shielding wall from extending between the two adjacent differential pairs 16. In this way, the main sheet body of the shielding sheet can be used to shield each differential pair 16 in the insulator on the side of the insulator, and the shielding wall of the shielding sheet can be used to extend between the two adjacent differential pairs 16 to achieve shielding between the two adjacent differential pairs 16, thereby improving the shielding effect and being conducive to improving the transmission rate of the connector.

[0045] The first shielding sheet 21 and the second shielding sheet 22 are respectively arranged on the two side portions in the thickness direction of the insulator. The first shielding sheet 21 and the second shielding sheet 22 are both shielding sheets with shielding walls. The main sheet body and the shielding wall of the first shielding sheet 21 are respectively a first main sheet body 211 and a first shielding wall 212. The main sheet body and the shielding wall of the second shielding sheet 22 are respectively a second main sheet body 221 and a second shielding wall 222. The first main sheet body 211 and the second main sheet body 221 are respectively located on the two sides in the thickness direction of the insulator. The shielding walls protrude inward. The inner space is the space between the first main sheet body 211 and the second main sheet body 221, that is, the space where the insulator and the differential pairs 16 are located. The shielding wall of one of the shielding sheets is in conductive connection with the shielding wall of the other shielding sheet. Specifically, the first shielding wall 212 of the first shielding sheet 21 is in conductive connection with the second shielding wall 222 of the second shielding sheet 22, so that the two shielding sheets are in common. This improves the shielding effect. In other embodiments, the two shielding sheets can not be in conductive contact.

[0046] In the embodiment, the shielding sheets are installed on both sides of the insulator in the thickness direction, which is conducive to improving the shielding effect. In other embodiments, the shielding sheet can be installed on only one side of the insulator in the thickness direction, and the shielding sheet on the other side can rely on the shielding sheet of the adjacent terminal module for shielding. In the embodiment, the first shielding sheet 21 and the second shielding sheet 22 are both shielding sheets with shielding walls, which facilitates reliable contact between the two shielding sheets. In other embodiments, a shielding wall can be provided on only one of the two shielding sheets, and the shielding wall on the other shielding sheet can not be provided. In this case, the shielding wall has a higher protruding height to conductively contact the inner side of the other shielding sheet.

[0047] The first shielding wall 212 of the first shielding sheet 21 and the second shielding wall 222 of the second shielding sheet 22 correspond to each other and are opposite in the thickness direction of the insulator. The shielding walls extend into the insulator. In the embodiment, the shielding walls have a rectangular cross-sectional shape perpendicular to the extending direction. In other embodiments, the shielding walls can have other shapes, such as trapezoidal shapes, as needed. The shielding walls protrude inwardly. The top surface of the protruding direction is the inner side of the shielding wall. The bottom of the protruding direction is connected to the main sheet body of the shielding sheet. The inner side of the shielding wall faces away from the main sheet body of the shielding sheet. The inner side of the first shielding wall 212 of the first shielding sheet 21 conductively contacts the inner side of the second shielding wall 222 of the second shielding sheet 22. After the two shielding sheets are installed, the inner sides of the two shielding walls are in close contact, which can better separate the two adjacent differential pairs 16, reduce crosstalk, and improve the shielding effect. In other embodiments, the shielding walls of the two shielding sheets can be staggered. The side surfaces of the shielding walls in the wall thickness direction of the two shielding sheets conductively contact each other. In this case, the shielding walls have a higher protruding height.

[0048] The inner side of the first shielding wall 212 of the first shielding sheet 21 is provided with a plug-in protrusion 213. The inner side of the second shielding wall 222 of the second shielding sheet 22 is provided with a groove 223 for fitting the plug-in protrusion 213. The groove 223 penetrates in the wall thickness direction of the shielding wall. The side surface of the plug-in protrusion 213 is flush with the side surface in the wall thickness direction of the shielding wall. After the shielding sheet is installed, the first main sheet body 211 and the second main sheet body 221 are attached to the corresponding side surfaces of the insulator. The inner sides of the two shielding walls are in contact. The plug-in protrusion 213 is inserted into the groove 223, which can enhance the reliability of the conductive contact and ensure the positions of the two shielding sheets. In other embodiments, the plug-in protrusion and the groove can not be provided. The inner sides of the shielding walls of the two shielding sheets are in close contact.

[0049] The groove 223 is provided with an interference fit protrusion that interferes with the side surface of the plug-in protrusion 213. The opposite two inner walls of the groove 223 in the extending direction of the shielding wall are arc-shaped walls to form the interference fit protrusion. The interference fit protrusion is combined with the plug-in protrusion 213 to form a conductive contact. Figure 6After the insertion protrusion 213 is inserted, the opposite sides of the insertion protrusion 213 in the shielding wall extension direction are in interference fit with the interference fit protrusions of the two sides of the groove 223, ensuring reliable contact and enhancing the stability of the shielding sheet. In other embodiments, the interference fit protrusions can also not be provided in the groove, and the opposite inner wall surfaces of the groove are flat, and the size of the insertion protrusion in the shielding wall extension direction is slightly larger than the groove width of the groove to form an interference fit.

[0050] The main sheet body of the shielding sheet is a metal sheet with a flat plate structure, the shielding wall includes a plastic base body injection molded on the main sheet body of the shielding sheet and a metal layer attached to the plastic base body, the plastic base body is fixed by the combination of the metal sheet inner surface and the plastic after injection molding, the metal layer is formed on the plastic base body by electroplating, and the metal layer is connected to the metal sheet to realize the conductive structure of the shielding wall. In this embodiment, the wall thickness of the shielding wall is greater than the thickness of the main sheet body to ensure the strength and formability of the shielding wall. In other embodiments, a conductive plastic can also be used to form the shielding wall, and the conductive plastic is integrally fixed to the metal sheet by injection molding. In order to increase the bonding strength of the plastic base body and the metal layer of the shielding wall, a bulge or a recess can be punched out on the metal sheet to increase the bonding area with the plastic. In other embodiments, a bending sheet can also be punched and bent inward on the metal sheet when the size is sufficient, and the bending sheet is used to form the shielding wall.

[0051] Since the terminal module has a plurality of differential pairs 16, a shielding wall is arranged between every two differential pairs 16, a plurality of shielding walls are arranged on the shielding sheet, the first shielding sheet 21 and the second shielding sheet 22 surround and shield the differential pairs 16 through the shielding walls, the adjacent two shielding walls of the first shielding sheet 21 and the corresponding adjacent two shielding walls of the second shielding sheet 22 form a cylindrical shielding cavity extending along the direction of the differential pairs 16, and the differential pairs 16 are located in the corresponding cylindrical shielding cavities to realize surrounding shielding. The most side differential pair 16 in the side-by-side direction of each differential pair 16 can be provided with or without a shielding wall according to the situation.

[0052] Each shielding wall includes at least two wall bodies arranged at intervals along the extending direction thereof. In the embodiment, the connector is a bent connector, the signal terminal 13 is a bent terminal, the signal terminals 13 of different differential pairs 16 are of different lengths, and correspondingly, the lengths of the shielding walls on the same shielding sheet are different. The shorter shielding wall can include only two wall bodies, and correspondingly, to ensure reliability, the recesses 223 or the plug convex portions 213 can be arranged on the different wall bodies. The interval between the adjacent two wall bodies of each shielding wall forms a break, the insulator has a portion located in the break, and the insulator forms a continuous material at the break to ensure the strength of the insulator, so that the shielding wall has sufficient extension length. The two ends of the shielding wall can extend to positions as close as possible to the two ends of the signal terminal 13, so as to form a surrounding shielding on the entire routing path of the signal terminal 13 as much as possible. In other embodiments, the break can not be arranged, and the overall length of the shielding wall can be shorter.

[0053] The first module unit 11 and the second module unit 12 constitute two mutually opposite module units of the terminal module, and the two module units are basically identical in structure. Figure 7 As shown in the first module unit 11, the module unit includes the insulating unit body 14 and the signal terminal 13 fixed in the insulating unit body 14. The insulating unit bodies 14 of the two module units jointly constitute the insulator of the terminal module, and the signal terminals 13 of the two module units are paired to form the differential pair 16. The main sheet bodies of the two shielding sheets are arranged at opposite sides of the two insulating unit bodies 14, respectively. One of the two signal terminals 13 of the differential pair 16 is fixed in the insulating unit body 14 of the first module unit 11, and the other is fixed in the insulating unit body 14 of the second module unit 12. The signal terminal 13 can be fixed in the insulating unit body 14 by one-piece injection molding.

[0054] In the embodiment, the two signal terminals 13 of the differential pair 16 are in the form of wide-side coupling, the connector does not have grounding terminals, the side surfaces of the two signal terminals 13 of the differential pair 16 in the thickness direction are opposite to each other, the spacing direction of the two signal terminals 13 of the differential pair 16 is perpendicular to the side-by-side direction of each differential pair 16, the two signal terminals 13 of the differential pair 16 are arranged side by side in the thickness direction of the insulator, and the thickness direction of the insulator is the arrangement direction of each terminal module of the connector. The two ends of the signal terminal 13 are respectively a plug-in end and a crimping end, the plug-in end is provided with a spring structure for cooperating with the plug pin of the mating connector, and the crimping end is provided with a fish-eye structure for being crimped and fixed on the printed board, the orientations of the plug-in end and the fish-eye end are perpendicular to each other to adapt to the structure of the bending connector. The thickness direction of the insulator of the terminal module is perpendicular to the orientations of the plug-in end and the fish-eye end of the signal terminal 13, the plug-in end and the fish-eye end of the signal terminal 13 respectively protrude from the insulator unit 14, the main sheet body of the shielding sheet covers one side of the insulator, one end of the shielding sheet close to the crimping end of the signal terminal 13 is provided with a fish-eye structure for conducting with the grounding circuit on the printed board, and one end of the shielding sheet close to the plug-in end of the signal terminal 13 is provided with a shielding connection site for conducting with the shielding structure of the mating connector. In other embodiments, the two signal terminals of the differential pair can also be in the form of narrow-side coupling, the side surfaces of the wire bodies of the signal terminals in the width direction are opposite to each other, the signal terminals of the same terminal module are arranged in a row, and the insulator can be in an integrated structure, and all the signal terminals are integrally fixed in the same insulator.

[0055] In combination Figure 8 As shown in the mounting structure of the first shielding sheet 21 and the first module unit 11, after the shielding sheet is mounted, the inner side surface of the shielding wall is flush with the inner side surface of the insulator unit 14, the protruding height of the shielding wall is set by the thickness of the insulator unit 14, which is convenient for molding and ensures the strength of the shielding wall. In other embodiments, the inner side surface of the shielding wall and the inner side surface of the insulator unit can also not be flush, and the protruding height of the shielding wall of one of the shielding sheets is lower and the protruding height of the shielding wall of the other shielding sheet is lower.

[0056] The insulation unit 14 is provided with an avoiding slot 15, which constitutes an avoiding slot for avoiding the shielding wall, so that the shielding wall extends between the two adjacent differential pairs 16. The avoiding slot 15 corresponds to each section of the shielding wall, and each avoiding slot 15 corresponding to the same shielding wall is embedded in the gap between the adjacent two sections of the wall, so that the avoiding slot 15 does not divide the insulation unit 14 into independent parts, and the insulation unit is ensured to be formed. The avoiding slot 15 is matched with the corresponding section of the shielding wall, and the shielding wall is embedded and installed in the avoiding slot, so that the shielding sheet can be fixed on the insulation unit 14, and the structure is simple and stable. In other embodiments, the avoiding slot can also be matched with the shielding wall, and at this time, a hot rivet column can be arranged on the insulation unit, and a rivet column perforation is arranged on the main sheet body of the shielding sheet. The hot rivet column passes through the rivet column perforation and is fixed to the insulation unit by hot riveting. In addition, for the fixation of the two insulation units 14, a fixing column can be arranged on one of the insulation units 14, and a fixing hole is arranged on the other. After the two module units are buckled together, the fixing column is inserted into the fixing hole in an interference fit to form a fixation.

[0057] The entire shielding sheet has a conductive property, and after the two shielding sheets are combined, the entire link of the wiring terminal is electrically shielded, the crosstalk is improved, the SI performance is improved, the wiring terminal is sleeve shielded, and the rate upgrade of the connector product is met.
