Description

Technical Field

[0001] This invention relates to the field of conductive connection device technology, and more specifically to an orthogonal connector and its wafer. Background Technology

[0002] In modern data communication transmission systems, transmission rates are constantly increasing, and high-speed interconnect systems are widely used in communication networks and data exchange systems. Orthogonal high-speed backplane connectors enable signal connectivity between two mutually perpendicular circuit boards and are widely used in core communication equipment such as switches and servers.

[0003] The structure of existing orthogonal connectors can be seen in Chinese invention patent CN112636046B, which discloses an orthogonal connector. This orthogonal connector includes a housing, in which multiple chips are arranged. Each chip includes an insulating frame, in which multiple signal differential pairs are fixed. Each signal differential pair includes two signal terminals, each signal terminal including a mounting end and a mating end, and a body portion located between the mounting end and the mating end. The mounting end is mounted on a first circuit board during use, and the mating end is directly plugged into an adapter connector during use. The body portion is located in the insulating frame. In order to accommodate the interconnection of two orthogonally distributed circuit boards, the mating end of the terminal is bent perpendicularly relative to the body portion, so that the thickness direction of the mating end is perpendicular to the thickness direction of the body portion. The parallel direction of the mating ends of the two signal terminals of the differential pair is perpendicular to the parallel direction of different differential pairs of the same chip, thus accommodating the interconnection of two mutually perpendicular circuit boards.

[0004] The signal terminals of the aforementioned orthogonal connector are bent terminals, the mating ends are contact ends, and the body is the wiring main body. In order to achieve a vertical transition from the wiring main body to the contact end, multiple bends are required during the manufacturing of the terminals. The bent parts of the terminals are prone to springback, which can affect the position accuracy of the contact end and thus easily lead to poor contact after the connector is plugged in. Summary of the Invention

[0005] The purpose of this invention is to provide a chip for an orthogonal connector to solve the problem that the terminal bending part of the current orthogonal connector chip is easily affected by springback, resulting in poor contact end positioning accuracy; the purpose of this invention is also to provide an orthogonal connector to solve the above problems.

[0006] The technical solution for the orthogonal connector chip of the present invention is as follows:

[0007] A chip for an orthogonal connector includes an insulator and a differential pair fixed in the insulator. The differential pair includes two signal terminals, each signal terminal including a trace body and a contact end. The trace body is connected to the contact end through a terminal bend. The insulator has an insulation retaining part that wraps around the terminal bend and shapes the terminal bend.

[0008] Furthermore, the insulation retaining portion is provided with a window, and the terminal bending portion has a portion protruding from the window.

[0009] Furthermore, the terminal bending portion includes a main body connection section that is connected to the main body of the wiring and is aligned with the thickness direction of the main body of the wiring. The side surface of the main body connection section in the thickness direction is coplanar with the corresponding side surface in the thickness direction of the main body of the wiring. The portion of the terminal bending portion exposed from the window is located in the main body connection section.

[0010] Furthermore, the two signal terminals of the differential pair have different extension lengths, and the area of ​​the portion of the longer signal terminal exposed from the window is greater than the area of ​​the portion of the shorter signal terminal exposed from the window.

[0011] Furthermore, a shielding sheet is provided on at least one side of the insulator in the thickness direction, the shielding sheet extending to the window and at least covering a portion of the window.

[0012] Furthermore, one end of the insulator near the contact end is provided with an extended protrusion for inserting into a clearance hole in the corresponding housing of the orthogonal connector, with each differential pair corresponding to one extended protrusion, and the insulation retaining portion is formed by the extended protrusion.

[0013] Furthermore, the terminal bends of the two signal terminals of the differential pair are arranged in a centrally symmetrical manner.

[0014] Furthermore, the insulator is provided with a grounding terminal, and at least one side of the insulator in the thickness direction is provided with a shielding sheet. The shielding sheet or the grounding terminal is provided with a connection part for connecting to a separately provided grounding contact.

[0015] Furthermore, the terminal bending portion includes a contact connection section and two transition sections arranged at an angle. The contact connection section is connected to the contact end and has the same thickness direction. One of the two transition sections is connected to the contact connection section, and the other is perpendicular to the thickness direction of the wiring body.

[0016] The beneficial effects of the orthogonal connector chip of the present invention are as follows: The present invention improves upon the existing orthogonal connector chip by providing an insulating retaining part on the insulator of the chip to wrap the bent portion of the terminal. The insulator wraps the bent portion of the signal terminal, which fixes the bent portion of the terminal. After the signal terminal is fixed together with the insulator, the bent portion of the terminal is shaped and the set bending state of the bent portion is maintained. It is not easily affected by springback, which helps to ensure the position accuracy of the contact end of the signal terminal and ensures reliable terminal contact after the connector is plugged in.

[0017] The technical solution of the orthogonal connector of the present invention is as follows:

[0018] An orthogonal connector includes a chip, the chip including an insulator and a differential pair fixed in the insulator, the differential pair including two pairs of signal terminals, the signal terminals including a trace body and a contact end, the trace body being connected to the contact end through a terminal bend, the insulator having an insulation retaining part that wraps around the terminal bend and shapes the terminal bend.

[0027] The beneficial effects of the orthogonal connector of the present invention are as follows: The present invention improves upon the chip of the existing orthogonal connector by providing an insulating retaining part on the insulator of the chip to wrap the bent portion of the terminal. The insulator wraps the bent portion of the signal terminal, which fixes the bent portion of the terminal. After the signal terminal is fixed together with the insulator, the bent portion of the terminal is shaped and the set bending state of the bent portion is maintained. It is not easily affected by springback, which helps to ensure the position accuracy of the contact end of the signal terminal and ensures reliable terminal contact after the connector is plugged in.

[0041] The orthogonal connector of the present invention utilizes the insulator of the chip to wrap the bent portion of the signal terminal, thereby shaping the bent portion of the terminal and maintaining the set bending state of the bent portion. It is not easily affected by springback, which helps to ensure the position accuracy of the contact end of the signal terminal.

[0042] Embodiments of the orthogonal connector of the present invention:

[0043] like Figure 1 , Figure 2 As shown, the orthogonal connector includes a housing 100, chips 200, a common ground housing 300, and a grounding contact 400. Multiple chips 200 are arranged side-by-side, and each chip 200 is fixedly mounted within the housing 100. Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8The chip 200 includes an insulator 25, terminals fixed in the insulator 25, and two shielding plates fixed on both sides of the thickness direction of the insulator 25. The terminals and shielding plates are all metal parts. The two shielding plates are the first shielding plate 21 and the second shielding plate 22. The terminals of the chip 200 include signal terminals 24 and ground terminals 23. The signal terminals 24 are arranged in pairs to form differential pairs. Multiple differential pairs are arranged side by side on the same chip 200, and a grounding terminal 23 is provided between any two differential pairs. The terminal is a wiring terminal. One end of the signal terminal 24 forms a contact end 242 for mating with a corresponding terminal of the adapter connector, and the other end forms a crimp end 243 for crimping onto a corresponding circuit board. The signal terminal 24 includes a wiring body 241 located between the contact end 242 and the crimp end 243. One end of the wiring body 241 is connected to the crimp end 243, and the other end is connected to the contact end 242 through a terminal bend 244. The crimp end 243 and the wiring body 241 are on the same plane, while the contact... The contact end 242 is perpendicular to the trace body 241. The thickness direction of the contact end 242 is perpendicular to the thickness direction of the trace body 241 by using the terminal bending portion 244. The parallel direction of the contact ends 242 of the two signal terminals 24 of the differential pair is perpendicular to the spacing direction of the crimp end 243. The parallel direction of each differential pair of the same chip 200 is perpendicular to the parallel direction of the contact ends 242 of the two signal terminals 24 of the same differential pair, so that the orthogonal connector and the adapter connector can be used to interconnect the two circuit boards that are orthogonally distributed.

[0044] The terminals of the chip 200 are fixed in the insulator 25 by injection molding. The insulator 25 is provided with an insulation holding part 251, which wraps around the terminal bending part 244. By wrapping the bending part of the signal terminal 244 with the insulator 25, the terminal bending part 244 is fixed and shaped. After the signal terminal 24 is fixed together with the insulator 25, the bending part of the signal terminal 24 is kept in the set bending state and is not easily affected by springback. This helps to ensure the position accuracy of the contact end 242 of the signal terminal 24 and ensures reliable terminal contact after the connector is plugged in.

[0045] The insulation holding part 251 is provided with a window 252, and the terminal bending part 244 has a portion exposed through the window 252. That is, a portion of the terminal bending part 244 is exposed to the air at the window. This portion is exposed through the window rather than protruding from it. The window 252 can be used to change the high-frequency signal transmission medium, optimize electromagnetic interference, reduce crosstalk, and improve transmission performance. The terminal bending part 244 includes a main body connecting section 2441, a first transition section 2442, a second transition section 2443, and a contact connecting section 2444. The main body connecting section 2441 is connected to the wiring body 241 and has the same thickness direction. The side surface of the main body connecting section 2441 in the thickness direction is coplanar with the corresponding side surface of the wiring body 241 in the thickness direction. The thickness of each part of the terminal corresponds to and is equal to the thickness of the strip used to form the terminal. The first transition section 2442 and the second transition section 2443 are arranged at an angle. The first transition section 2442 is connected to the main body connecting section 2441 and is perpendicular to the main body connecting section 2441. One end of the second transition section 2443 is connected to the first transition section 2442, and the other end is connected to the contact connecting section 2444. The contact connecting section 2444 is connected to the contact end 242 and has the same thickness direction. The first transition section 2442 is parallel to the contact end 242. The insulation holding part 251 wraps around the contact connecting section 2444 and the main body connecting section 2441. The portion of the terminal bending part 244 that protrudes from the window 252 is located in the main body connecting section 2441. The main body connecting section 2441 that is connected to the wiring main body 241 extends straight. The straight section protrudes from the window 252, which facilitates the control of the open area of ​​the window 252 and facilitates the forming of the window 252.

[0046] The terminals of the chip 200 are bent terminals. All terminals of the same chip 200 are formed on the same strip. The contact end 242 and the crimping end 243 of the signal terminal 24 are perpendicular to each other. Accordingly, for the arrangement of each terminal on the chip 200, the length of each terminal is different. The longer the contact end 242 is from the circuit board to which the corresponding terminal is crimped, the longer the terminal is. The two signal terminals 24 of the differential pair have different extension lengths. The area of ​​the longer signal terminal 24 exposed from the window 252 is larger than the area of ​​the shorter signal terminal 24 exposed from the window 252, which can improve the time delay difference between the two signal terminals 24 of the differential pair. Each differential pair corresponds to an insulation holding part 251. The terminal bending portions 244 of both signal terminals 24 of the same differential pair have portions exposed through windows 252. Windows 252 extend through the thickness direction of the insulator 25. The main connecting section 2441 of the terminal bending portion 244 and the main trace 241 both have portions exposed through windows 252, with a portion in the width direction also exposed. That is, a portion of the main connecting section 2441 of the terminal bending portion 244 and the main trace 241 corresponding to the window 252 is partially within the insulator 25 in the width direction, ensuring structural strength. The opening area of ​​the longer signal terminal 24 in window 252 is larger than the opening area of ​​the shorter signal terminal 24, facilitating the exposure of the signal terminal 24 through window 252. Both signal terminals 24 of the same differential pair are exposed through the same window 252, resulting in a simple structure and ease of manufacturing.

[0047] The first shielding plate 21 and the second shielding plate 22 both extend from the main body of the insulator 25 near the insertion end. The first shielding plate 21 and the second shielding plate 22 extend to the window 252 and cover part of the window 252, which can play a shielding role at the window 252 and ensure the shielding effect.

[0048] An extension protrusion is provided at one end of the insulator 25 near the contact end 242 for insertion into the common housing 300 of the orthogonal connector. Each differential pair corresponds to one extension protrusion. The insulation retaining part 251 is formed by the extension protrusion, which protrudes from the main body of the insulator 25 toward the plug end, facilitating the insertion of the insulation retaining part 251 into the common housing 300. This ensures reliable installation of the chip 200 and helps reduce the size of the connector. The insulation retaining part 251 increases the strength at the bend of the signal terminal 24, effectively improving the pin retraction problem caused by the chip 200 during assembly into the common housing 300. Even if the chip 200 is not properly aligned with the common housing 300 during installation, it will not bend the contact end 242 of the signal terminal 24. At the same time, the plastic of the insulation retaining part 251 acts as an insulator, reducing the risk of metal shavings generated by the chip 200 scraping against the common housing 300 during assembly, which could lead to poor voltage withstand.

[0049] The terminal bends 244 of the two signal terminals 24 of the differential pair are arranged symmetrically at the center. The center of the terminal bends 244 of the two signal terminals 24 of the differential pair is also the center of the distance between the two signal terminals 24. The bending directions of each segment of the terminal bends 244 of the two signal terminals 24 are opposite. The two parts of the insulation holding part 251 that respectively wrap around the two terminal bends 244 of the differential pair are staggered. By making the terminal bends 244 of the two signal terminals 24 of the differential pair symmetrical about their centers, the coupling performance of the differential pair at the terminal bends 244 can be improved while achieving the orthogonal arrangement of the two contact ends 242 of the differential pair relative to the trace body 241.

[0050] The grounding terminal 23 in the insulator 25 of the aforementioned chip 200 does not have a contact portion that mates with the adapter connector. Both the grounding terminal 23 and the signal terminal 24 have a crimping structure for crimping to the circuit board. The grounding connection with the adapter connector is achieved through a separately provided grounding contact 400. The grounding contact 400 is installed in the common ground housing 300 and contacts and mates with the corresponding terminal of the adapter connector. The first shielding plate 21 of the chip 200 has a connection portion for connecting with the separately provided grounding contact 400. By using the separately provided grounding contact 400 to connect with the first shielding plate 21 to form grounding connection, it is not necessary to provide a contact on the grounding terminal 23. This facilitates the symmetrical bending of the signal terminal 24 and makes it easier for the terminal to be processed and formed on the material strip.

[0051] The outer shell 100 is an insulating shell, and the common ground shell 300 is a conductive shell. The common ground shell 300 is installed in the outer shell 100. Each chip 200 forms a grounding connection with the common ground shell 300. The common ground shell 300 is made by electroplating metal on a plastic substrate. The grounding contact 400 is a metal part that passes through the common ground shell 300. The common ground shell 300 has mounting holes for mounting the grounding contact 400. The two ends of the grounding contact 400 in the length direction are a mating end and a connecting end, respectively. The mating end of the grounding contact 400 is used to mate with the corresponding terminal of the adapter connector. The connecting end of the grounding contact 400 away from the mating end protrudes from the corresponding mounting hole of the common ground shell 300 and connects with the first shielding plate 21 of the chip 200 when the chip 200 is installed in the outer shell 100 to achieve grounding connection. The grounding contact 400 is connected to the common ground shell 300 and the first shielding plate 21, which is conducive to reliable grounding connection.

[0052] The first shielding plate 21 has a shielding plate slot 211 at its edge near the insertion end of the signal terminal 24. The connection end of the grounding contact 400 is connected and grounded by snapping into the shielding plate slot 211. The first shielding plate 21 has an opening groove 212 on the side of the shielding plate slot 211. The opening groove 212 allows one side wall of the shielding plate slot 211 to be deformable. When the connection end of the corresponding grounding contact 400 is snapped into the shielding plate slot 211, it provides deformation clearance space for the deformation of the shielding plate slot 211 of the first shielding plate 21, which facilitates the insertion of the corresponding grounding contact 400 into the shielding plate slot 211 and reduces metal debris.

[0053] The housing 100 has a partition to divide the inner cavity of the housing 100 into an installation space and a mating space. The ground housing 300 is installed in the installation space of the housing 100. The mating end of the grounding contact 400 extends into the mating space of the housing 100. The chip 200 is installed in the installation space of the housing 100 and the contact end 242 of its signal terminal 24 extends into the mating space to be mated with the adapter connector.

[0054] Combination Figure 9 , Figure 10 The common housing 300 is provided with grounding mounting holes 301, a first slot 311, a second slot 312, and clearance holes 321. The grounding mounting holes 301 form mounting holes for mounting grounding contacts 400. The grounding mounting holes 301 are arranged in rows, and correspondingly, the grounding contacts 400 are arranged in rows. One row of grounding contacts 400 corresponds to one chip 200. Grounding contacts 400 are provided between the contact ends 242 of any two differential pairs of the same chip 200. The clearance holes 321 are arranged in rows, and the number of clearance holes 321 in the same row is the same as the number of differential pairs of the same chip 200. The clearance holes 321 are used to insert the insulation holding part 251 of the insulator 25 of the chip 200. The contact ends 242 of the differential pairs of the chip 200 can pass through the partition of the housing 100 and extend into the mating space. The first slot 311 and the second slot 312 are arranged in a group, with each group corresponding to one chip 200. The first slot 311 is for the first shielding sheet 21 to be inserted, and the second slot 312 is for the second shielding sheet 22 to be inserted. One end of the shielding sheet extending from the main body of the insulator 25 is inserted into the corresponding slot, and the part of the shielding sheet inserted into the slot is provided with a bulge so that the chip 200 and the common ground housing 300 can form a grounding connection.

[0055] The thickness direction of the grounding contact 400 is perpendicular to the thickness direction of the grounding terminal 23 and the shielding sheet. The thickness direction of the grounding contact 400 is consistent with the thickness direction of the contact end 242 of the signal terminal 24, adapting to the arrangement of the orthogonal connector. This orthogonal connector is a male connector, and its adapter connector is a female connector. The contact end 242 of the signal terminal 24 has a pin structure, and the grounding contact 400 is a grounding pin. The mating end of the grounding contact 400 has a pin structure, and the grounding pin is used to contact and mate with the grounding spring structure of the adapter connector.

[0056] The grounding contact 400 has interference-fit protrusions on both sides in the width direction to interfere with the grounding mounting hole 301 on the common ground housing 300. One side of the grounding contact 400 in the thickness direction has a straightening bulge, which abuts against the wall of the grounding mounting hole 301 to prevent the grounding contact 400 from tilting within the grounding mounting hole 301. The end of the grounding mounting hole 301 facing the wafer 200 forms an insertion port for the grounding contact 400 to be inserted into the grounding mounting hole 301. When fully inserted, the limiting shoulder of the grounding contact 400 engages with the edge of the insertion port to ensure the proper mounting position of the grounding contact 400.

[0057] In other embodiments, if the transmission performance meets the requirements, the window may not be provided in the insulation retention section.

[0058] In other embodiments, the first transition section of the terminal bend may be exposed through the window.

[0059] In other embodiments, if space permits, the shielding sheet can be configured to completely cover the window.

[0060] In other embodiments, the two terminal bends of the differential pair may not be symmetrical bends, as long as the orthogonal arrangement of the terminals is met.

[0061] In other embodiments, a connection portion for connecting to a separately provided grounding contact may be provided at the edge of the grounding terminal.
