Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically to a connector and connector assembly. Background Technology

[0002] In modern data communication transmission systems, transmission rates are increasing, and high-speed interconnect systems are widely used in communication networks and data exchange systems. With the development of aerospace technology, the communications industry has begun to deploy 6G commercial communications based on satellite communication technology. The market for high-reliability aerospace-grade interconnect solutions is vast, with increasing demand from the civilian commercial aerospace sector in addition to traditional military and defense needs.

[0003] High-reliability aerospace-grade connectors typically use pin-hole contacts, where pin contacts and socket contacts are mated together. Both pin and socket contacts are machined and then press-fitted into an insulating plastic housing. This insulating plastic housing containing the contacts is then encased in a metal shell. To ensure reliable contact, pin contacts often use twisted pins. For example, a high-speed surface-mount connector for parallel PCB boards, disclosed in Chinese invention patent application CN107482331A (published December 15, 2017), uses signal pins for the plug and ground pins for the ground contacts, both twisted pins. Similarly, the socket uses signal jacks for the signal contacts and ground jacks for the ground contacts, both of which are pin-shaped contacts with round holes. The contacts are designed to mate with pins. The ends of the pin contacts and socket contacts used for mating form mating terminals. The pin contacts and socket contacts are respectively fixedly mounted on the plug base and socket base. The plug base is embedded in the plug housing, and the socket base is embedded in the socket housing. Both the plug housing and socket housing are metal housings, and both the plug base and socket base are insulators. Mounting holes are provided on the insulators, and the contacts pass through these mounting holes. The space within the mounting holes on the socket base for the plug contacts to insert forms a mating channel. Each pair of corresponding contacts forms a differential pair for transmitting differential signals. However, this connector still has limitations when transmitting high-speed signals; crosstalk can easily occur at the plug-socket mating point, affecting the high-speed signal transmission rate. Summary of the Invention

[0004] The purpose of this invention is to provide a connector that solves the problem of insufficient signal transmission rate of current connectors; another purpose of this invention is to provide a connector assembly that solves the problem of insufficient signal transmission rate of current connectors.

[0005] The technical solution of the connector of the present invention is as follows:

[0006] A connector includes an insulator and contacts disposed on the insulator. The contacts have mating ends. The insulator has a mating channel for an adapter connector to be inserted into. The mating ends of the contacts are located within the mating channel. The contacts include signal contacts and ground contacts. A shielding cover is provided around the mating channel. The shielding cover has a through hole and a clearance hole. The ground contact passes through the through hole and makes conductive contact with the shielding cover. The signal contact passes through the clearance hole and is insulated from the shielding cover. The clearance hole corresponds to the mating channel for the adapter connector to be inserted into.

[0007] Beneficial effects: This invention improves upon the existing connector pin or socket contact mounting structure by adding a conductive shield at the mating end of the contact. The conductive shield has through holes for grounding contacts to pass through and make contact with each other, while the conductive shield has clearance holes for signal contacts to pass through and be spaced apart. This ensures normal signal transmission from the signal contacts while simultaneously shielding and connecting the grounding contacts through conductive contact, improving shielding effectiveness, reducing crosstalk, and ultimately increasing signal transmission rate.

[0008] Furthermore, it also includes a metal casing, an insulator installed inside the metal casing, a conductive shield installed on the insulator, and the conductive shield being insulated from the metal casing.

[0009] Beneficial effects: It insulates the metal casing from the conductive shield, thereby isolating the grounding of the metal casing from the grounding of the connector signal transmission, ensuring that the signal transmission process is not affected by external interference.

[0010] Furthermore, the insulator is provided with a mounting cavity, and the conductive shield is installed in the mounting cavity. The cavity wall of the mounting cavity insulates and separates the conductive shield from the metal shell.

[0011] Beneficial effects: By setting an installation cavity on the insulator, the conductive shield is isolated from the metal shell by the insulator, which ensures reliable insulation and facilitates the fixing of the conductive shield.

[0012] Furthermore, the insulator includes an insulating cap and an insulating base. The insulating cap has a cylindrical structure, including a bottom and an opening. The end of the insulating cap with the opening is fastened to the insulating base to form an installation cavity. The end of the insulating cap with the bottom has a first hole and a second hole corresponding to the through hole and the clearance hole, respectively, so that the corresponding grounding contact and signal contact are exposed.

[0013] Beneficial effects: By setting up the insulator separately, the conductive shield is installed in the mounting cavity formed by the insulating cap and the insulating base. This allows the conductive shield to be fixed by the insulating cap and the insulating base. At the same time, the insulating cap and the insulating base can wrap a large area around the conductive shield, which helps to ensure the insulation performance.

[0014] Furthermore, the contacts are pin contacts, the signal contacts are twisted pins, and the grounding contacts are round pins.

[0015] Beneficial effects: Using a combination of twisted needles and ordinary round needles can help save costs. Ordinary round needles have strong rigidity and are less prone to needle buckling.

[0016] Furthermore, the insulator has a grounding pin through hole and a signal pin mounting protrusion on the end face near the connector mating end. The mating end of the grounding contact passes through the grounding pin through hole, and the signal pin mounting protrusion has a receiving hole, in which the mating end of the signal contact is received.

[0017] Beneficial effects: By setting a receiving hole on the signal pin mounting protrusion, the coiled pin can be protected. At the same time, a recess is formed on the periphery of the signal pin mounting protrusion, and the grounding contact extends out of the recessed space. This allows the connector's mating end to form a structure with the recess and protrusion interlocking, which facilitates the mating with the mating end of the adapter connector and helps to ensure a stable mating.

[0018] Furthermore, the contacts are socket contacts, the signal contacts are round hole pins, and the grounding contacts are open hole pins.

[0019] Beneficial effects: Round hole pins can be fitted and inserted with coiled pins, and open hole pins can be fitted and inserted with round pins, making it easy for the connector to be fitted and inserted with the corresponding adapter connector.

[0020] Furthermore, the mating end of the grounding contact is accommodated in the through hole of the conductive shield, while the mating end of the signal contact is located in the clearance hole of the conductive shield.

[0021] Beneficial effects: The conductive shield's through-hole accommodates the mating end of the grounding contact, which is beneficial for the contact between the conductive shield and the grounding contact. It also protects the open pins from misalignment and pin failure. At the same time, the gap between the clearance hole wall and the signal contact allows the mounting protrusions of the signal pins on the insulator of the adapter connector to be embedded, which is beneficial for a stable mating.

[0022] Furthermore, the insertion end of the open-hole needle has an insertion hole, the wall of the insertion hole is provided with a groove extending along the axial direction of the insertion hole, and a contact protrusion is provided in the through hole, the contact protrusion being offset from the groove.

[0023] Beneficial effect: After the open-hole pin is inserted into the matching round pin, due to the presence of the groove, the insertion of the round pin into the hole will cause the mating end of the open-hole pin to deform, thereby making reliable contact between the ungrooved part of the mating end and the contact protrusion.

[0024] Furthermore, the split groove has two or more locations, and the part of the open hole needle located between two adjacent split grooves constitutes a segmented body, with the ends of each segmented body converging together.

[0025] Beneficial effects: By bringing the ends of each segment together to form a smaller head, the smaller head plays a guiding role during the assembly of the opening pin, reducing the generation of plastic debris. At the same time, it helps to avoid wear and contact protrusions.

[0026] The technical solution of the connector assembly of the present invention is as follows:

[0027] A connector assembly includes a plug and a socket that mates with the plug, the plug or socket constituting a connector. The connector includes an insulator and contacts disposed on the insulator. The contacts have mating ends. The insulator has a mating channel for the mating connector to be inserted into. The mating ends of the contacts are located within the mating channel. The contacts include signal contacts and ground contacts. A shielding cover is provided around the mating channel. The shielding cover has a through hole and a clearance hole. The ground contact passes through the through hole and makes conductive contact with the shielding cover. The signal contact passes through the clearance hole and is insulated from the shielding cover. The clearance hole corresponds to the mating channel for the mating connector to be inserted into.

[0028] Beneficial effects: This invention improves upon the existing connector pin or socket contact mounting structure by adding a conductive shield at the mating end of the contact. The conductive shield has through holes for grounding contacts to pass through and make contact with each other, while the conductive shield has clearance holes for signal contacts to pass through and be spaced apart. This ensures normal signal transmission from the signal contacts while simultaneously shielding and connecting the grounding contacts through conductive contact, improving shielding effectiveness, reducing crosstalk, and ultimately increasing signal transmission rate.

[0029] Furthermore, it also includes a metal casing, an insulator installed inside the metal casing, a conductive shield installed on the insulator, and the conductive shield being insulated from the metal casing.

[0030] Beneficial effects: It insulates the metal casing from the conductive shield, thereby isolating the grounding of the metal casing from the grounding of the connector signal transmission, ensuring that the signal transmission process is not affected by external interference.

[0031] Furthermore, the insulator is provided with a mounting cavity, and the conductive shield is installed in the mounting cavity. The cavity wall of the mounting cavity insulates and separates the conductive shield from the metal shell.

[0032] Beneficial effects: By setting an installation cavity on the insulator, the conductive shield is isolated from the metal shell by the insulator, which ensures reliable insulation and facilitates the fixing of the conductive shield.

[0033] Furthermore, the insulator includes an insulating cap and an insulating base. The insulating cap has a cylindrical structure, including a bottom and an opening.

The end of the insulating cap with the bottom has a first hole and a second hole corresponding to the through hole and the clearance hole, respectively, so that the corresponding grounding contact and signal contact are exposed.

[0034] Beneficial effects: By setting up the insulator separately, the conductive shield is installed in the mounting cavity formed by the insulating cap and the insulating base. This allows the conductive shield to be fixed by the insulating cap and the insulating base. At the same time, the insulating cap and the insulating base can wrap a large area around the conductive shield, which helps to ensure the insulation performance.

[0035] Furthermore, the contacts are pin contacts, the signal contacts are twisted pins, and the grounding contacts are round pins.

[0036] Beneficial effects: Using a combination of twisted needles and ordinary round needles can help save costs. Ordinary round needles have strong rigidity and are less prone to needle buckling.

[0037] Furthermore, the insulator has a grounding pin through hole and a signal pin mounting protrusion on the end face near the connector mating end. The mating end of the grounding contact passes through the grounding pin through hole, and the signal pin mounting protrusion has a receiving hole, in which the mating end of the signal contact is received.

[0038] Beneficial effects: By setting a receiving hole on the signal pin mounting protrusion, the coiled pin can be protected. At the same time, a recess is formed on the periphery of the signal pin mounting protrusion, and the grounding contact extends out of the recessed space. This allows the connector's mating end to form a structure with the recess and protrusion interlocking, which facilitates the mating with the mating end of the adapter connector and helps to ensure a stable mating.

[0039] Furthermore, the contacts are socket contacts, the signal contacts are round hole pins, and the grounding contacts are open hole pins.

[0040] Beneficial effects: Round hole pins can be fitted and inserted with coiled pins, and open hole pins can be fitted and inserted with round pins, making it easy for the connector to be fitted and inserted with the corresponding adapter connector.

[0041] Furthermore, the mating end of the grounding contact is accommodated in the through hole of the conductive shield, while the mating end of the signal contact is located in the clearance hole of the conductive shield.

[0042] Beneficial effects: The conductive shield's through-hole accommodates the mating end of the grounding contact, which is beneficial for the contact between the conductive shield and the grounding contact. It also protects the open pins from misalignment and pin failure. At the same time, the gap between the clearance hole wall and the signal contact allows the mounting protrusions of the signal pins on the insulator of the adapter connector to be embedded, which is beneficial for a stable mating.

[0043] Furthermore, the insertion end of the open-hole needle has an insertion hole, the wall of the insertion hole is provided with a groove extending along the axial direction of the insertion hole, and a contact protrusion is provided in the through hole, the contact protrusion being offset from the groove.

[0044] Beneficial effect: After the open-hole pin is inserted into the matching round pin, due to the presence of the groove, the insertion of the round pin into the hole will cause the mating end of the open-hole pin to deform, thereby making reliable contact between the ungrooved part of the mating end and the contact protrusion.

[0045] Furthermore, the split groove has two or more locations, and the part of the open hole needle located between two adjacent split grooves constitutes a segmented body, with the ends of each segmented body converging together.

[0046] Beneficial effects: By bringing the ends of each segment together to form a smaller head, the smaller head plays a guiding role during the assembly of the opening pin, reducing the generation of plastic debris.

[0075] The present invention will be further described in detail below with reference to the embodiments.

[0076] Embodiment 1 of the connector assembly of the present invention:

[0077] like Figure 1 , Figure 2 , Figure 3 As shown, the connector assembly includes a plug and a socket, which are mated together. Both the plug and socket are rectangular connectors. The plug is used to connect cables, and the socket is used to connect printed circuit boards. The plug includes a plug housing 11, a tail clip 12, and a plug contact module installed inside the plug housing 11. Two plug contact modules are arranged side by side. Each plug contact module includes a plug insulator 15 and a plug contact 16. The plug contact 16 includes a plug signal contact and a plug ground contact. The plug signal contact is a pin 161, and the plug ground contact is a round pin 162. The socket includes a socket housing 21 and a socket contact module. There are two socket contact modules. Each socket contact module includes a socket insulator, a conductive shield 25, and a socket contact 22. The socket contact 22 includes a socket signal contact and a socket ground contact. The socket signal contact is a round hole pin 221, and the socket ground contact is an open hole pin 222. The plug has a plug insertion end that is adapted to be inserted into the socket, and the socket has a socket insertion end that is adapted to be inserted into the plug. When the plug and the socket are inserted, the pin 161 of the plug is adapted to be inserted into the round hole pin 221 of the socket, and the round pin 162 of the plug is adapted to be inserted into the open hole pin 222 of the socket.

[0078] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, the tail clip 12 of the plug is located on the side of the plug opposite to the plug insertion end. The tail clip 12 is for the cable to pass through and connect to the plug contact 16. The plug housing 11 is a metal housing, which includes a main housing and an outer ring platform located around the main housing. The outer ring platform is used to support the end face of the tail clip 12 when it is fastened onto the plug housing 11. The plug has a length direction and a width direction perpendicular to the insertion direction. The main housing of the plug housing 11 has two module mounting holes along the length direction of the plug to install two plug contact modules respectively. The plug has an inner ring platform inside the module mounting hole, and the plug insulator 15 of the plug contact module has an annular step. After the plug insulator 15 is installed into the module mounting hole, the inner ring platform and the annular step form a stop fit to limit the plug insulator 15. The annular step on the plug insulator 15 has an anti-misalignment notch 151, which is offset to one side in the length direction. The inner wall of the module mounting hole of the plug housing 11 has a protrusion corresponding to the anti-misalignment notch 151. Thus, during installation, the plug insulator 15 can only be installed into the corresponding module mounting hole after the anti-misalignment notch 151 is aligned with the corresponding protrusion, thus preventing misinstallation.

[0079] The plug insulator 15 has various contact fixing holes, and each plug contact 16 is interference-fitted into the contact fixing holes. Each plug insulator 15 has two rows of plug contacts 16, spaced apart along the width of the plug and spaced apart along the length of the plug. The plug contacts 16 are pin contacts. For each row of plug contacts 16, there are multiple plug signal contacts and multiple plug ground contacts. Twisted pins 161 are arranged in pairs, with each pair of twisted pins 161 forming a differential pair. Each differential pair has round pins 162 on both sides, and two round pins 162 are located between adjacent differential pairs. The differential pairs of the two rows of plug contacts 16 are staggered. The contact fixing hole includes a grounding pin through hole and a signal pin through hole. A signal pin mounting protrusion 152 is provided on the end face of the plug insulator 15 near the plug insertion end. There are multiple signal pin mounting protrusions 152, and each signal pin mounting protrusion 152 is spaced apart and arranged in two rows along the width direction of the plug. Each row of signal pin mounting protrusions 152 is spaced apart along the length direction of the plug. The signal pin through hole is provided on the signal pin mounting protrusion 152, and the differential pair is mounted on the same signal pin mounting protrusion 152. The grounding pin through hole 153 is provided on the end face of the plug insulator 15 near the plug insertion end. The mating end of the round pin 162 passes through the grounding pin through hole 153 to be exposed at the plug insertion end. The mating end of the coiled pin 161 is located in the signal pin through hole. The part of the signal pin through hole located on the signal pin mounting protrusion 152 constitutes a receiving hole 154 on the signal pin mounting protrusion 152 for accommodating the mating end of the round pin 162. Using a combination of coiled pin 161 and ordinary round pin 162 helps save costs. Ordinary round pin 162 has strong rigidity and is less prone to pin failure when exposed. Containing coiled pin 161 in receiving hole 154 can protect coiled pin 161. The hole of the signal pin at the plug insertion end has a flared structure to guide the round hole pin 221 on the socket when the plug and socket are plugged in.

[0080] like Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21As shown, the socket has a length direction and a width direction perpendicular to the insertion direction. The socket housing 21 is a metal housing, and the socket housing 21 has two module mounting holes along the length direction of the plug to install two socket contact modules respectively. The module mounting holes on the socket have an inner ring platform 211 facing away from the insertion end. The socket insulator of the socket contact module has an annular step 243. After the socket insulator is inserted into the corresponding module mounting hole from the side facing away from the socket insertion end, the inner ring platform 211 and the annular step 243 in the socket housing 21 form a stop fit to limit the socket insulator. The annular step of the socket insulator has a notch, which is offset to one side in the length direction. The inner wall of the module mounting hole of the socket housing 21 has a protrusion corresponding to the notch. In this way, during installation, the socket insulator can only be inserted into the corresponding module mounting hole after the notch is aligned with the corresponding protrusion, preventing incorrect installation.

[0081] The socket contact 22 is a socket contact. Each socket contact module has two rows of socket contacts 22 corresponding to the plug contacts 16. The round pins 221 are arranged in pairs to form differential pairs. Each differential pair of the socket has open pins 222 on both sides, and there are two open pins 222 between adjacent differential pairs. Both the open pins 222 and the round pins 221 are L-shaped pins. The L-shaped pin includes a horizontal section and a vertical section. The horizontal section is used to form solder leads for soldering to the printed circuit board, and the vertical section is interference-fitted onto the socket insulator.

[0082] The socket insulator includes an insulating cap 24 and an insulating base 26. The insulating cap 24 has a cylindrical structure, including a bottom and an opening, with the opening facing away from the socket's insertion end. One end of the insulating cap 24 with the opening is attached to the insulating base 26, which is located within the inner cavity of the insulating cap 24. An annular step on the socket insulator is provided on the outer wall of the insulating cap 24. The end face of the insulating base 26 near the socket's insertion end, the inner side of the bottom of the insulating cap 24, and the inner wall of the cylindrical surface form an installation cavity. A conductive shield 25 is installed within the installation cavity. The conductive shield 25 is made of conductive plastic or electroplated plastic and is insulated from the socket housing 21 by the cavity wall. The insulating base 26 has a guide post 261, and the conductive shield 25 has a guide adapter hole. When the conductive shield 25 and the insulating base 26 are assembled together, the conductive post and the guide adapter hole guide and match to ensure the corresponding position of the hole.

[0083] The insulating base 26 is provided with contact fixing holes for interference fit of each socket contact 22. The conductive shield 25 is provided with a through hole 251 and a clearance hole 252. The through hole 251 corresponds to the contact fixing hole for fixing the open hole pin 222, and the clearance hole 252 corresponds to the contact fixing hole for fixing the round hole pin 221. Every two contact fixing holes for fixing differential pairs correspond to one clearance hole 252. The bottom of the insulating cap 24 is provided with a first hole 242 and a second hole 241 corresponding to the through hole 251 and the clearance hole 252, respectively. The through hole 251 is a round hole and is adapted to the outer diameter of the socket contact 22. The clearance hole 252 is a square hole and its radial dimension is much larger than the outer diameter of the socket contact 22. When fixing the socket contact 22, the vertical sections of the open hole pin 222 and the round hole pin 221 are interference-fitted into the corresponding contact fixing holes of the insulating base 26, and the mating ends of the open hole pin 222 and the round hole pin 221 pass through the contact fixing holes. The mating end of the open hole pin 222 enters the through hole 251 of the conductive shield 25 and makes conductive contact with the conductive shield 25. The mating end of the round hole pin 221 enters the clearance hole 252 of the conductive shield 25 and is spaced apart from the hole wall of the clearance hole 252. The first hole 242 is matched with the through hole 251 to allow the open hole pin 222 to be exposed. The second hole 241 is matched with the square hole of the clearance hole 252 to allow the differential pair to be exposed. Both the first hole 242 and the second hole 241 are flared to facilitate the insertion of the contact.

[0084] By insulating the socket housing 21 from the conductive shield 25, the grounding of the metal housing can be separated from the grounding of the connector signal transmission, ensuring that the signal transmission process is not affected by external interference. The through-hole 251 of the conductive shield 25 accommodates the mating end of the open pin 222, which facilitates contact between the conductive shield 25 and the grounding contact, and also protects the open pin 222 from misalignment and pin failure.

[0085] The opening pin 222 has a socket at its mating end. The wall of the socket has a slot 2221 extending axially along the socket. Two slots 2221 are symmetrically arranged. The portion of the opening pin 222 located between the two slots 2221 forms a split body. The two slots 2221 cause the mating end of the opening pin 222 to form two split bodies. A contact protrusion 2511 is provided inside the through hole 251. After the opening pin 222 extends into the through hole 251, the contact protrusion 2511 is offset from the slot 2221, and contacts the split body after the round needle 162 is inserted into the opening pin 222. The two split bodies are then connected near the socket. The ends of the pins converge to form a smaller head, which guides the insertion of the socket insulator from the side opposite to the socket connector during the assembly of the pin 222, reducing the generation of plastic debris. It also helps to avoid wear on the contact protrusion 2511. The insertion port of the pin 222 for the round needle 162 is flared. The round needle 162 has a pointed tip to guide the insertion of the round needle 162. The round needle 162 is inserted into the insertion port of the pin 222 and splits the two segments, so that the segments form a top-pressure contact with the contact protrusion 2511.

[0086] Since the plug insulator 15 has a signal pin mounting protrusion 152 on the end face near the plug insertion end, a recess is formed in the space surrounding the signal pin mounting protrusion 152. This creates a structure where the recess and protrusion are staggered at the plug insertion end. Correspondingly, the signal mounting protrusion is a square protrusion that matches the clearance hole 252. The portion of the socket insulator occupied by the clearance hole 252 and the portion occupied by the opening pin 222, together with the first hole 242 and the second hole 241, constitute the insertion channel on the socket insulator for plug insertion. That is, the space occupied by the plug insertion on the socket insulator forms the insertion channel for the corresponding part of the plug to be inserted. The conductive shield 25 constitutes the shielding cover around the insertion channel. When the plug and socket are connected, the gap between the wall of the clearance hole 252 and the round hole pin 221 allows the signal pin mounting protrusion 152 on the plug insulator 15 to be inserted, thereby enabling the twisted pin 161 of the plug located in the signal pin through hole and the round hole pin 221 of the socket located in the clearance hole 252 to be inserted into each other, and the round pin 162 of the plug extending in the recessed space and the open hole pin 222 of the socket located in the through hole 251 to be inserted into each other. The plug end and the plug end of the socket form a concave-convex fit, which is conducive to a stable connection.

[0087] The tail clip 12 has plug locking screws 13 on both sides of the plug's length direction, arranged diagonally. The plug housing 11 has plug guide pins 14 on both sides of the plug's length direction, also arranged diagonally. The plug locking screws 13 and guide pins 14 on the same side of the plug's length direction are arranged side-by-side along the plug's width direction, with the two locking screws 13 and guide pins 14 located at the four corners of the rectangular connector. The socket housing 21 has socket locking screws 23 and socket guide holes on both sides of the socket's length direction, arranged diagonally, and located at the four corners of the rectangular connector. The socket locking screw 23 has a fixing nut at the end near the socket plug end. The nut is used to cooperate with the plug locking screw 13 to lock the plug and socket after the plug and socket are plugged in. The socket locking screw 23 has a screw nut at the end opposite the socket plug end to lock the socket to the printed circuit board. The diagonally arranged plug guide pins 14 cooperate with the socket guide holes to guide the plug and socket plugging and prevent incorrect plugging.

[0088] In use, the plug and socket are connected. The round pin 162 of the plug is inserted into the open pin 222 on the socket, and the twisted pin 161 of the plug is inserted into the round pin 221 on the socket, forming signal conduction and grounding conduction. The conductive shield 25 is used to wrap the mating end of the open pin 222. The conductive shield 25 can shield and conduct each grounding contact through conductive contact with the open pin 222, improving the shielding effect, reducing crosstalk, and helping to improve the signal transmission rate. This is beneficial to meeting the high reliability and high transmission rate requirements of commercial communication satellites for connectors.

[0089] Embodiment 2 of the connector assembly in this invention:

[0090] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the plug signal contact is a coiled pin and the socket signal contact is a round hole pin. In this embodiment, both the plug signal contact and the plug ground contact are round pins, and correspondingly, both the socket signal contact and the socket ground contact are open hole pins. In this case, the plug end no longer has a signal pin mounting protrusion.

[0091] Embodiment 3 of the connector assembly in this invention:

[0092] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the socket insulator has a mounting cavity, and the conductive shield is installed inside the mounting cavity, with the cavity wall insulatingly separating the conductive shield from the metal casing of the socket. In this embodiment, however, the conductive shield is located on the side of the insulator closer to the socket's insertion end. The conductive shield is embedded and fixed on the insulator, and is spaced apart from the socket casing. The air gap between the conductive shield and the socket casing insulatingly separates the conductive shield from the metal casing of the socket.

[0093] Embodiment 4 of the connector assembly in this invention:

[0094] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the socket insulator includes an insulating cap and an insulating base. The insulating cap is a cylindrical structure, including a bottom and an opening. One end of the insulating cap with the opening is fastened to the insulating base to form a mounting cavity. The end of the insulating cap with the bottom has a first hole and a second hole corresponding to the through hole and the clearance hole, respectively, so that the corresponding grounding contact and signal contact are exposed. In this embodiment, the socket insulator is a mounting groove with an opening facing the socket insertion end. The opening of the mounting groove is open, and the conductive shield is installed in the mounting groove. The groove wall of the mounting groove insulates and separates the conductive shield from the metal shell of the socket.

[0095] Embodiment 5 of the connector assembly in this invention:

[0096] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the plug has a pin contact and the socket has a socket contact. In this embodiment, the plug has a socket contact and the socket has a pin contact. Correspondingly, the round needle passes through the through hole on the conductive shield and exits through the first hole on the insulating cap. The insulating base has a protrusion that extends into the clearance hole on the conductive shield. The protrusion has a needle insertion hole for the needle to pass through. In order to make the needle on the socket flush with the round needle, the protrusion protrudes a portion of the opening of the clearance hole to ensure that the needle can be accommodated.

[0097] Embodiment 6 of the connector assembly in this invention:

[0098] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the through hole has a contact protrusion that makes conductive contact with the opening pin. In this embodiment, however, the through hole does not have a contact protrusion, and the opening pin makes direct conductive contact with the hole wall. In other embodiments, the opening pin has a stepped surface facing the socket insertion end, and the stepped surface presses against the end face of the conductive shield away from the socket insertion end to achieve conductive contact.

[0099] Embodiment 7 of the connector assembly in this invention:

[0100] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, each differential pair has a grounding contact on both sides, and two grounding contacts are provided between two adjacent differential pairs. In this embodiment, however, there is only one grounding contact between two adjacent differential pairs.
