DETAILED DESCRIPTION

[0028] The orthogonal connector of the present invention uses the insulator of the chip to wrap the bending part of the signal terminal, shape the bending part of the terminal, maintain the set bending state of the bending part, and is not easily affected by rebound, which is beneficial to ensure the position of the contact end of the signal terminal.

[0029] Embodiments of the orthogonal connector of the present invention: like Figure 1 , Figure 2 As shown, the orthogonal connector includes a housing 100, a chip 200, a common ground shell 300 and a ground contact 400. A plurality of chips 200 are arranged in parallel, and each chip 200 is fixedly installed in the housing 100. Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The chip 200 includes an insulator 25, terminals fixed in the insulator 25, and two shielding plates respectively fixed on both sides of the insulator 25 in the thickness direction. The terminals and the shielding plates are both metal parts. The two shielding plates are respectively a first shielding plate 21 and a 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 and constitute differential pairs. The same chip 200 is provided with multiple differential pairs side by side and a ground terminal 23 is provided between any two differential pairs. The terminal is a wiring terminal, one end of the signal terminal 24 constitutes a contact end 242 for mating with a corresponding terminal of the adapter connector, and the other end constitutes a crimping end 243 for crimping on a corresponding circuit board. The signal terminal 24 includes a wiring body 241 located between the contact end 242 and the crimping end 243, one end of the wiring body 241 is connected to the crimping end 243, and the other end is connected to the contact end 242 through a terminal bending portion 244, the crimping end 243 and the wiring body 241 are in the same plane, and the contact The end 242 is perpendicular to the wiring body 241, and the terminal bending portion 244 is used to make the thickness direction of the contact end 242 perpendicular to the thickness direction of the wiring body 241, 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 crimping end 243, and the side-by-side direction of each differential pair of the same chip 200 is perpendicular to the side-by-side 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 cooperate to interconnect two orthogonally distributed circuit boards.

[0030] The terminals of the chip 200 are fixed in the insulator 25 as the insulator 25 is injection molded. The insulator 25 is provided with an insulating retaining portion 251. The insulating retaining portion 251 wraps the terminal bending portion 244. The insulator 25 is used to wrap the bending part of the signal terminal 24 to fix the terminal bending portion 244 and shape the terminal bending portion 244. After the signal terminal 24 is molded and fixed together with the insulator 25, the bending part of the signal terminal 24 can be kept in a set bending state and is not easily affected by rebound, which is beneficial to ensuring the position of the contact end 242 of the signal terminal 24 and ensuring reliable terminal contact after the connector is plugged in.

[0031] The insulating holding portion 251 is provided with a window 252, and the terminal bending portion 244 has a portion exposed from the window 252, that is, a portion of the terminal bending portion 244 is exposed to the air at the window, and the portion is exposed by the window instead of extending from the window. The window 252 can change the high-frequency signal transmission medium, optimize electromagnetic interference, reduce crosstalk, and improve transmission performance. The terminal bending portion 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 main body 241 and is consistent in 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 main body 241 in the thickness direction. The thickness of each part of the terminal is equal to the thickness of the material 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, and the insulating holding portion 251 wraps the contact connecting section 2444 and the main body connecting section 2441. The portion of the terminal bending portion 244 exposed from the window 252 is located in the main body connecting section 2441, and the main body connecting section 2441 connected to the wiring main body 241 extends straight, and the straight section is exposed from the window 252, so as to control the open area of ​​the window 252 and facilitate the molding of the window 252.

[0032] The terminals of the chip 200 are bent terminals. The terminals of the same chip 200 are processed and formed on the same material strip. The contact end 242 of the signal terminal 24 is perpendicular to the crimping end 243. Accordingly, for the arrangement of the terminals on the chip 200, the lengths of the terminals are different. The farther the contact end 242 is from the circuit board to which the corresponding terminal is crimped, the longer the terminal length is. The two signal terminals 24 of the differential pair have different extension lengths, wherein 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 delay difference between the two signal terminals 24 of the differential pair. Each differential pair corresponds to an insulating holding portion 251. The terminal bending portions 244 of the two signal terminals 24 of the same differential pair both have a portion exposed from the window 252. The window 252 penetrates along the thickness direction of the insulator 25. The main body connecting section 2441 of the terminal bending portion 244 and the wiring main body 241 both have a portion exposed from the window 252, and a portion in the width direction is exposed from the window 252, that is, the main body connecting section 2441 of the terminal bending portion 244 and the wiring main body 241 corresponding to the window 252 have a portion in the width direction inside the insulator 25, ensuring the structural strength. The opening area of ​​the window 252 corresponding to the longer signal terminal 24 is larger than the opening area of ​​the shorter signal terminal 24, which facilitates the signal terminal 24 to be exposed from the window 252. The two signal terminals 24 of the same differential pair are exposed from the same window 252, which has a simple structure and is easy to manufacture.

[0033] The ends of the first shielding sheet 21 and the second shielding sheet 22 close to the plug-in end extend out of the main part of the insulator 25. The first shielding sheet 21 and the second shielding sheet 22 extend to the window 252 and cover a part of the window 252, which can shield the window 252 and ensure the shielding effect.

[0034] An extension protrusion is provided at one end of the insulator 25 near the contact end 242 for extending into the common ground shell 300 of the orthogonal connector. Each differential pair corresponds to an extension protrusion. The insulating retaining portion 251 is formed by the extension protrusion. The extension protrusion protrudes toward the plug end based on the main body of the insulator 25, which facilitates the insulating retaining portion 251 to be installed in the common ground shell 300, ensuring that the chip 200 is installed reliably and is conducive to reducing the size of the connector. The insulating retaining portion 251 can increase the strength of the bend of the signal terminal 24, and can effectively improve the pin shrinkage problem caused by the assembly of the chip 200 to the common ground shell 300. Even if the chip 200 is not well aligned with the common ground shell 300 during the installation process, the contact end 242 of the signal terminal 24 will not be bent. At the same time, the plastic of the insulating retaining portion 251 plays an isolating role, which can reduce the risk of poor voltage resistance caused by metal shavings caused by the scraping of the chip 200 with the common ground shell 300 during assembly.

[0035] The terminal bending parts 244 of the two signal terminals 24 of the differential pair are arranged symmetrically with respect to the center, the center of the terminal bending parts 244 of the two signal terminals 24 of the differential pair also corresponds to the center of the distance between the two signal terminals 24, the bending directions of the sections of the terminal bending parts 244 of the two signal terminals 24 are opposite, and the two parts of the insulating holding part 251 that respectively wrap the two terminal bending parts 244 of the differential pair are arranged in a staggered manner. The terminal bending parts 244 of the two signal terminals 24 of the differential pair are made symmetrical about the centers of the two terminals, and the coupling performance of the differential pair at the terminal bending parts 244 can be improved while realizing the orthogonal arrangement of the two contact ends 242 of the differential pair relative to the wiring body 241.

[0036] The grounding terminal 23 in the insulator 25 of the above-mentioned chip 200 does not have a contact part that cooperates with the adapter connector. The grounding terminal 23 and the signal terminal 24 are both provided with a crimping structure for crimping to the circuit board, and the grounding connection with the adapter connector is achieved through a separately arranged grounding contact 400. The grounding contact 400 is installed in the common ground shell 300, and the grounding contact 400 is in contact with and cooperates with the corresponding terminal of the adapter connector. The first shielding sheet 21 of the chip 200 is provided with a connection portion for connecting with the separately arranged grounding contact 400. When the separately arranged grounding contact 400 is connected to the first shielding sheet 21 to form a ground connection, it is not necessary to set a contact on the grounding terminal 23, which is conducive to realizing symmetrical bending of the signal terminal 24 and facilitating the processing and forming of the terminal on the material strip.

[0037] The 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 shell 100. Each chip 200 forms a ground 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. The grounding contact 400 is inserted into the common ground shell 300. The common ground shell 300 is provided with a mounting hole for installing the grounding contact 400. The two ends of the grounding contact 400 in the length direction are respectively a plug-in end and a connecting end. The plug-in end of the grounding contact 400 is used to cooperate with the corresponding terminal of the adapter connector. The connecting end of the grounding contact 400 away from the plug-in end is exposed from the corresponding mounting hole of the common ground shell 300 and is connected to the first shielding sheet 21 of the chip 200 when the chip 200 is installed in the shell 100 to achieve ground connection. The grounding contact 400 is connected to the common ground shell 300 and the first shielding sheet 21, which is conducive to reliable ground connection.

[0038] The edge of the first shielding sheet 21 near the plug-in end of the signal terminal 24 is provided with a shielding sheet snap-in 211. The connecting end of the grounding contact 400 is connected and grounded by snapping into the shielding sheet snap-in 211. The first shielding sheet 21 is provided with an opening groove 212 beside the shielding sheet snap-in 211. The opening groove 212 can make a side wall of the shielding sheet snap-in 211 deformable. When the connecting end of the corresponding grounding contact 400 is snapped into the shielding sheet snap-in 211, a deformation avoidance space is provided for the deformation of the shielding sheet snap-in 211 of the first shielding sheet 21, so that the corresponding grounding contact 400 is snapped into the shielding sheet snap-in 211 and metal debris is reduced.

[0039] A partition is provided inside the shell 100 to divide the inner cavity of the shell 100 into an installation space and a plug-in space. The common ground shell 300 is installed in the installation space of the shell 100, and the plug-in end of the ground contact 400 extends to the plug-in space of the shell 100. The chip 200 is installed in the installation space of the shell 100 and the contact end 242 of its signal terminal 24 extends to the plug-in space to mate with the adapter connector.

[0040] Combination Fig. 9 , Fig.10 The common ground shell 300 is provided with a grounding mounting hole 301, a first card slot 311, a second card slot 312, and a avoidance hole 321. The grounding mounting hole 301 constitutes a mounting hole for mounting the grounding contact 400. The grounding mounting holes 301 are arranged in a row. Accordingly, the grounding contacts 400 are arranged in a row. One row of grounding contacts 400 corresponds to one chip 200. A grounding contact 400 is arranged between any two differential pairs of contact ends 242 of the same chip 200. The avoidance holes 321 are arranged in a row. The number of avoidance holes 321 in the same row is consistent with the number of differential pairs of the same chip 200. The avoidance holes 321 are used to install the insulating holding portion 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 to the insertion space. The first card slot 311 and the second card slot 312 are arranged in a group, and one group corresponds to a chip 200. The first card slot 311 is for the first shielding sheet 21 to be inserted, and the second card slot 312 is for the second shielding sheet 22 to be inserted. One end of the shielding sheet extending out of the main body of the insulator 25 is inserted into the corresponding card slot, and a bulge is provided on the part of the shielding sheet inserted into the card slot, so that the chip 200 and the common ground shell 300 can form a ground connection.

[0041] The thickness direction of the grounding contact 400 is perpendicular to the thickness direction of the grounding terminal 23 and the shielding sheet, and the thickness direction of the grounding contact 400 is consistent with the thickness direction of the contact end 242 of the signal terminal 24, which is adapted to the arrangement of the orthogonal connector. The orthogonal connector is a male connector, and its adapter connector is a female connector. The contact end 242 of the signal terminal 24 is a pin structure, and the grounding contact 400 is a grounding pin. The plug-in end of the grounding contact 400 is a pin structure, and the grounding pin is used to contact and cooperate with the grounding spring structure of the adapter connector.

[0042] Both sides of the grounding contact 400 in the width direction are provided with interference protrusions to be interference-fitted with the grounding mounting hole 301 on the ground-common housing 300. One side of the grounding contact 400 in the thickness direction is provided with a convex straightening bulge, which is used to abut against the hole wall of the grounding mounting hole 301 to prevent the grounding contact 400 from deflecting in the grounding mounting hole 301. The hole opening at one end of the grounding mounting hole 301 facing the wafer 200 constitutes an insertion port for the grounding contact 400 to be inserted into the grounding mounting hole 301. When the grounding contact 400 is installed in place, the limiting shoulder of the grounding contact 400 cooperates with the edge of the insertion port to ensure the installation position of the grounding contact 400.

[0043] In other embodiments, when the transmission performance meets the requirements, it is not necessary to set the window in the insulating holding portion.

[0044] In other implementations, the first transition section of the bent portion of the terminal may also be exposed from the window.

[0045] In other implementations, if space permits, the shielding sheet may also be configured to be a structure that can completely cover the window.

[0046] In other implementations, the two terminal bending portions of the differential pair may not be symmetrically bent, as long as the requirement for orthogonal terminal arrangement is met.
