[0021] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment may also be beneficially combined in other embodiments without further description.

[0022] It should be noted that: unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by persons having ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express a quantitative limitation, but rather indicate the presence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0023] As shown in the figure, this embodiment provides a bent female connector. The bent female connector 100 includes a contact component and a common ground component 3 at the plug-in end. The contact component includes an injection molded component 1, a shielding plate assembly 2, a socket shielding contact 4, and a differential signal pair 5. A differential signal pair 5 is provided inside each injection molded component 1, wherein the differential signal pair 5 is used to realize the transmission of differential signals. The head end of the signal plug 51 of the differential signal pair 5 extends into the interior of the metal socket shielding contact 4. Each signal plug 51 includes two relatively arranged springs assembled to form a signal pin 501 adapted to be inserted into the interior of the two springs to achieve electrical connection. The tail end of the differential signal pair 5 is provided with a tail terminal 52 and passes through the positioning plate 8. The contact components are arranged in sequence on the positioning plate 8.

[0024] In this solution, each socket shielding contact 4 is independently provided, so that the shielding contact structure has a certain degree of adaptability, which can improve the reliability of shielding with the bent male connector 200. The structure of the socket shielding contact 4 is described below: the socket shielding contact 4 includes a base 41, a claw portion 42 provided at the head end of the base 41, and a connecting head 44 provided on both sides of the tail end of the base 41. The base 41 has a C-shaped structure, including a base plate 411 and side plates 412 located on both sides of the base plate 411; Preferably, the side panels 412 are perpendicular to the base plate 411 and utilize a circular transition. The claw portion 42 includes claws I 421 and II 422, with claws II 422 symmetrically positioned on either side of claw I 421. Preferably, claw I 421 is provided with a row of contact claws. The tail end of claw I 421 is connected to and integral with the base plate 411, while the head end of claw I 421 is free. The claw portion 42 is configured to achieve shielded electrical connection with the plug shield contact 40 of the male connector 200. A connector 44 extends from the side panels 412 toward the tail end and is configured to provide shielded electrical connection with the head end connection portion of the shielding plate assembly 2. Claws III 43 are also provided on the side panels 412 on either side of the base 41. Claws III 43 protrude outward from the base 41 and are configured to electrically contact the inner wall of the plug cavity 31 of the plug-end common ground component 3. Specifically, bosses 33 are provided on opposite sides of the insertion cavity 31 near the rear end. The bosses 33 are capable of achieving and maintaining reliable electrical contact with the spring claws III 43. Furthermore, the bosses 33 cooperate with the spring claws III 43 to form a mating gap between the two sides of the receptacle shield contact 4 and the insertion cavity 31 for mating with the plug shield contact 40 of the bent male connector 200. This mating gap is in communication with the corresponding slot 75. In this embodiment, the length of the spring claws I 421 along the insertion direction is greater than the length of the spring claws II 422 along the insertion direction, allowing the spring claws I 421 to extend into the slot 75 on the periphery of the jack socket 74 and be positioned within the receiving groove 744 on the outer wall of the jack socket 74. The receiving groove 744 is located on one side of the slot 75 and the two are in communication. However, the spring claw II 422 does not extend into the slot 75. When the bent male connector and the bent female connector are plugged in, under the guidance of the slot 75, the spring claw II 422 is shielded and abutted against the plug shielding contact 40 of the matching bent male connector 200 to be connected. Since the head end of the spring claw II 422 is located at the tail end of the jack seat 74, the head end of the spring claw II 422 will not directly collide with the plug shielding contact 40 of the bent male connector 200 during the plug-in process, thereby avoiding damage to the spring claw.

[0025] In this embodiment, the receptacle shielding contacts 4 are neatly arranged in rows and columns. A row of metal shielding claws 6 are provided at one end of the array formed by the receptacle shielding contacts 4. These claws 6 are used to mate with the shielding tail plate 60 of the adaptor bent male connector 200. The structure of the claws 6 is described below: Several claws 6 are provided in a row. The leading ends of the claws 6 are provided with spring claws IV 61 and the trailing ends with clamping arms 63. These two clamping arms 63 are positioned opposite each other and, after passing through the slots 11 of the injection molded component 1, make electrical contact with the end surfaces of the shielding sheet assembly 2. Opposite sides of the clamping arms 63 are provided with raised contacts II 64, which are used to make electrical contact with the end surfaces of the shielding sheets I 21 and II 22. A protrusion 62 is provided on the end surface of the mid-section base plate of the claw 6, which abuts against one side of the inner wall of the slot 11.

[0026] In this embodiment, the socket shielding contact 4 is made into a C-shaped structure as a whole, so that elastic contact points extend from the front and two side surfaces in three directions to contact and conduct with the metal shielding part (plug shielding contact 40) on the matching bent male connector 200, thereby increasing the electromagnetic shielding effect. Lateral contact points extend from both sides of the base 41 to electrically contact the common ground part 3 at the plug-in end. With this design, all the socket shielding contacts 4 are connected to the common ground, and the connectors 44 on both sides of each socket shielding contact 4 are respectively shielded and conducted with the shielding pieces I 21 and II 22 on both sides of the injection-molded component 1.

[0027] The following describes the structure of the contact components: The injection-molded components 1 are single-shot contact components. Each injection-molded component 1 contains multiple differential signal pairs 5 for signal transmission. The leading ends of the differential signal pairs 5 form signal plugs 51, which consist of two opposing springs. The gap between the two springs accommodates the signal pins 501 of the curved male connector 200. The trailing ends of the differential signal pairs 5 are provided with tail terminals (e.g., fisheye terminals) 52, which can be passed through by the positioning plate 8. Shielding sheet assemblies 2 are provided on both sides of the injection-molded components 1.

[0028] The structure of the shielding plate assembly 2 can be implemented as follows: the shielding plate assembly 2 includes a shielding plate I 21 and a shielding plate II 22, wherein the shielding plates I 21 and II 22 are respectively disposed on two oppositely disposed end surfaces of the injection-molded component 1, and are used to provide electromagnetic shielding for the differential signal pair 5 within the injection-molded component 1. The leading ends of the shielding plates I 21 and II 22 are each provided with a connection portion that electrically contacts the receptacle shielding contact 4. The connection portion includes a connecting plate I 23 and a connecting plate II 24. The connecting plate I 23 is configured to connect to the tail end connector 44 of the receptacle shielding contact 4. Preferably, the connecting plate I 23 is disposed perpendicularly to the main bodies of the shielding plates I 21 and II 22, respectively, and is formed with a hole I 231. The hole I 231 is used to electrically connect to the tail end of the receptacle shielding contact 4. Specifically, the tail end of the receptacle shielding contact 4 is provided with a connector 44, which is provided with a hole II 441. Connector 44 snaps into hole I 231 to achieve electrical connection. Hole II 441 allows connector 44 to contract toward hole II 441 when the two metal parts are connected, resulting in a certain amount of deformation. Connector I 23 can be formed by bending the shielding plate body away from its corresponding injection molded component 1. Connector I 23 and connector II 24 are arranged in a spaced relationship and perpendicular to each other, so that after installation, connector I 23 can cover the opening at the tail end of the receptacle shielding contact 4, preventing the tail end of the receptacle shielding contact 4 from being exposed, thereby achieving a better electromagnetic shielding effect. At the same time, connector I 23 and connector II 24 are arranged vertically, and the interference contact here adopts a line-surface fit, which facilitates the installation and positioning of the receptacle shielding contact 4. The connecting piece II 24 can be formed by extending the shielding piece body toward the head end. A protruding contact I 241 capable of electrically contacting the end surface of the substrate 411 of the socket shielding contact 4 is formed on the narrow side of the connecting piece II 24 .

[0029] In a typical embodiment of the present invention, the insulating housing 7 includes an outer frame 71, the interior of the outer frame 71 is divided into rows of cavities by an inner partition 72, and each row of cavities is provided with a plurality of jack seats 74. Specifically, after the outer frame 71 is divided into rows of cavities by the inner partition 72, a positioning guide column 76 is provided in each row of cavities perpendicular to the inner partition 72. The positioning guide column 76 divides the row of cavities into independent plug-in cavities, and a jack seat 74 is provided on the inner partition 72 of each plug-in cavity; one side of the jack seat 74 is fixed on the inner partition 72, and the other three sides of the jack seat 74 are adjacent to the inner partition 72 and the positioning guide column 76. A C-shaped slot 75 is formed between the other three sides of the outermost jack seat 74 and the adjacent inner partition 72, the positioning guide column 76, and the outer frame 71 to form a C-shaped slot 75. The slot 75 is set to pass through along the plug-in direction. The slot 75 is used to adapt to the insertion of the plug shielding contact 40 of the bent male connector 200. A row of tail slots 77 are set at the end of the plug-in cavity 31. The tail slot 77 is provided with a head end for the shielding tail claw 6 to extend into it, and the tail slot 77 is used to adapt to the shielding tail plate 60 of the bent male connector 200 to extend into it, so as to realize the shielding conduction of the shielding tail claw 6 and the shielding tail plate 60.

[0030] As shown in the figure, the jack seat 74 is provided with a jack 741 along the plugging direction. Preferably, the jacks 741 are through-through and arranged in pairs along the plugging direction, and are separated by a barrier 747 between the two jacks 741. The jacks 741 are used to pass through the pins of the differential signal pair 50 of the adapter curved male connector 200 and extend into the signal plug 51 to achieve signal connection. The head end of the jack seat 74 is formed with an outer plugging bevel 742 near the edge of the slot 75. The outer plugging bevel 742 is used to guide the insertion of the plug shield contact 40 of the adapter curved male connector 200. The head end of the jack seat 74 is formed with an inner plugging bevel 743 near the edge of the jack 741. The inner plugging bevel 743 is used to guide the insertion of the signal pins 501 of the adapter curved male connector 200. The side of the jack socket 74 facing away from the inner partition 72 to which it is connected is provided with a receiving slot 744. The function of the receiving slot 744 is to accommodate the spring claw I 421, so that the head end of the spring claw I 421 is placed in the receiving slot 744. In order to ensure that the spring claw I 421 can elastically deform and avoid the groove, the bottom of the receiving slot 744 is provided with an avoidance slope. Support guide blocks 746 are provided on both sides of the receiving slot 744. The function of the support guide blocks 746 is to guide the plug shield contact 40 of the adapter connector into the insertion position of the slot 75. The structure of the positioning guide column 76 is described below. The two sides of the head end of the positioning guide column 76 are provided with plugging surfaces 761 respectively. The plugging surfaces 761 include inclined surfaces located at the notch of the slot 75 on both sides. The plugging surfaces 761 are used to guide the plug shield contact 40 of the bent male connector 200 into the slot 75. A stop positioning surface 762 is formed on one side of the tail end of the positioning guide column 76. The stop positioning surface 762 is used to cooperate with the plug-in end common ground member 3 to stop and position.

[0031] In this embodiment, the signal plug 51 at the head end of the differential signal pair 5 corresponds to the two jacks 741 of the jack seat 74, and an isolation block 745 is provided on the inner wall of the side away from the two jacks 741. The isolation block 745 is used to position and separate the two springs of the signal plug 51 to facilitate the insertion of the signal pin 501 of the adapter connector into the two springs of the corresponding signal plug 51 to achieve electrical connection and reduce the insertion force.

[0032] The structure of the plug-in end common ground member 3 is described below: the plug-in end common ground member 3 is provided with an array arrangement on its upper edge, and the function of the plug-in cavity 31 is to install the socket shielding contact 4 and make electrical contact with the socket shielding contact 4. The plug-in cavity 31 is divided into independent square plug-in cavities 31 by horizontal plates and vertical plates. The horizontal plate or the vertical plate extends toward the head end to form a positioning plate 32. The function of the positioning plate 32 is to be able to be inserted between the two adjacent inner partitions 72 of the insulating shell 7 from the tail end, and the positioning plate 32 can abut against the stop positioning surface 762 of the positioning guide column 76 to limit the relative position between the plug-in end common ground member 3 and the insulating shell 7 along the axial direction (plug-in direction).

[0033] In order to achieve the connection between the insulating shell 7, the plug-in end common ground piece 3 and the injection molded component 1, a card slot or card hole 78 is provided on the insulating shell 7, and card blocks I 12 are provided on the opposite sides of the injection molded component 1. The outer periphery of the plug-in end common ground piece 3 is also provided with a card block II 34. The card block I 12 of the injection molded component 1 and the card block II 34 of the plug-in end common ground piece 3 respectively cooperate with the corresponding card holes 71 of the insulating shell 7 to achieve the assembly of the above components.

[0034] In the above structure of the present solution, shielding pieces I 21 and II 22 are respectively provided on both sides of the injection molded component 1, and then a socket shielding contact 4 is connected to one side of the head end of the shielding piece I 21 and the shielding piece II 22, so that the above components and the socket shielding contact 4 are assembled to form a complete contact component, which is convenient for subsequent assembly processes, and then the above contact components are assembled with the plug-in end common ground component 3 and the insulating shell 7, thereby optimizing the order of automated assembly and greatly improving the assembly yield and assembly efficiency.

[0035] The present solution also provides a connector assembly, comprising the above-mentioned bent female connector 100 and a bent male connector 200 adapted thereto.

[0036] In order to make the principle of this solution clearer, the structure of the bent male connector 200 adapted to the bent female connector 100 of this case is described below: the head end of the bent male connector 200 (the plug end that cooperates with the bent female connector 100 is its head end) is docked with the head end of the bent female connector 100 to achieve adaptive plugging. Specifically, the bent male connector 200 includes an adapter contact component, a plug shielding contact 40, an adapter plug end common ground component 30 and a male end shell 70, wherein the plug shielding contact 40 includes a main shielding component 401 and a secondary shielding component 402 that are detachably connected, and the main shielding component 40 1 includes a plug barrel 4011, a shielding plate 4013, and an elastic arm 4014. The plug barrel 4011 is a square cylindrical structure with a shielding cavity provided along its axial direction. Protruding contacts III for achieving snap-in connection are provided on the outer wall of the plug barrel 4011. The protruding contacts III are located on the four outer walls of the plug barrel 4011 and are outwardly protruding structures formed by the outer walls. They are used to electrically contact the plug shielding contact 40 with the mating plug-end common ground member 30. The plug barrel 4011 is fixed in the mating slot 301 of the mating plug-end common ground member 30 via the protruding contacts III. The opposite side walls of the plug-in barrel 4011 extend toward the head end to form a shielding plate 4013. The shielding plates 4013 on both sides are arranged parallel to each other, and a clamping gap is formed between the two shielding plates 4013. The secondary shielding part 402 is inserted into the clamping gap and fixed. The same side of the two shielding plates 4013 is provided with an outward-tilted elastic arm 4014. The elastic arm 4014 is located on both sides of the secondary shielding part 402, and the fixed end of the elastic arm 4014 is connected to the shielding plate 4013. The free end of the elastic arm 4014 protrudes from the outer side surface of the shielding plate 4013 when it is in a free state without force. A movable gap is reserved between the elastic arm 4014 and the secondary shielding part 402 for the elastic arm 4014 to be compressed. When the bent female connector 100 and the bent male connector 200 are plugged in place, the two relative elastic arms 4014 are used to rest against the inner wall of the plug-in cavity 31 of the common ground part 3 of the plug-in end of the bent female connector 100 after being compressed. Specifically, the two opposing elastic arms 4014 are located at corresponding positions of the shielding plate 4013 and are symmetrically arranged with respect to each other.

[0037] In this embodiment, the mating contact components of the bent male connector 200 include a male injection molded component 10 and a male shielding plate assembly 20. The male shielding plate assembly 20 comprises a first shielding plate and a second shielding plate disposed oppositely on either side of the male injection molded component 10. Each male injection molded component 10 houses a differential signal pair 50 for differential signal transmission. The first and second shielding plates are each shielded and electrically connected to the tail ends of the plug shielded contacts 40. A contact claw, a first cantilever arm and a second cantilever arm are provided at the head end of the first shielding piece, which extend into the interior of the plug barrel 4011 of the plug shielding contact 40 through the contact claw, the first cantilever arm and the second cantilever arm, and respectively contact the inner walls on three sides of the plug barrel 4011. Specifically, the contact claw contacts one inner wall of the plug barrel 4011 along the thickness direction of the shielding piece, and the first cantilever arm and the second cantilever arm contact the other two oppositely arranged inner walls of the plug barrel 4011 along the width direction of the shielding piece, and the two oppositely arranged inner walls are perpendicular to the inner wall contacted by the contact claw; the plug shielding contact 4 is fixed from three directions, thereby improving the reliability of the contact between the first shielding piece and the plug shielding contact 4. A third cantilever arm is provided at the head end of the second shielding plate. The third cantilever arm extends into the gap between two adjacent plug shielding contacts 4 and is tightly fitted with the opposite outer side walls of the two adjacent plug shielding contacts 4. The outer side wall contacted by the third cantilever arm refers to the outer side wall of the side wall contacted by the first cantilever arm and the second cantilever arm.

[0038] In this solution, a raised contact IV is formed on the outer wall of the secondary shielding member 402. The raised contact IV is a convex structure raised from the outer wall. The raised contact IV is located near the tail end of the secondary shielding member 102. The raised contact IV on the outer wall is used to contact the inner wall of the plug-in slot 301 of the common ground member 30 of the adapter plug-in end. The clamping surfaces on both sides of the secondary shielding member 402 are also provided with raised contacts V. The secondary shielding member 402 is fixed in the gap between the two shielding plates 4013 by clamping with the raised contacts V.

[0039] In this solution, both raised contacts III and IV are raised bump structures. The plug shield contact 40 electrically contacts the mating common ground element 30, ensuring electrical continuity across all metal plug shield contacts 40 on the connector, effectively improving signal transmission performance. After assembly, the signal pins 501 (pins) at the leading end of the male differential signal pair 50 are located within the mating cavity 403 of the plug shield contact 40. They are shielded on three sides by the shield plate 4013 of the primary shield 401 and the secondary shield 402. Simultaneously, the notch 4015 at the leading end of the plug shield contact 40 provides shielding for the pins on that side through the adjacent plug shield contact 40 located on either side of the notch 4015. This design ensures that each differential pair pin is shielded on all sides, improving transmission performance.

[0040] In this embodiment, the head end of the plug shielding contact 40 is exposed outward from the plug-in interface of the adapter plug-end common ground member 30 and extends into the adapter insulating housing 70 . When the bent male connector 200 and the bent female connector 100 are plugged into place, the signal pin 501 (pin pin) of the male end signal differential pair 50 of the bent male connector 200 extends into the signal plug 51 of the differential signal pair 5 of the bent female connector 100 to achieve electrical connection, and the plug shielding contact 40 extends into the slot 75 of the bent female connector 100 to achieve shielding conduction with the socket shielding contact 4. Specifically, the spring claw I 421 and the spring claw II 422 of the socket shielding contact 4 are placed inside the plug shielding contact 40, the spring claw I 421 is in electrical contact with the end face of the auxiliary shielding component 402, and the spring claw II 422 is in electrical contact with the end face of the shielding plate 4013, thereby achieving shielding conduction between the bent male connector 200 and the bent female connector 100. In addition, the spring arm 4014 will pass through the slot 75 and achieve shielding conduction with the inner wall of the plug cavity 31 of the common ground component 3 of the plug end of the bent female connector 100.

[0041] The bent male connector 200 is also provided with a shielding tail plate 60. Specifically, a shielding tail plate 60 is provided on one side of the notch 4015 of the last row of plug shielding contacts 40. The shielding tail plate 60 is combined with the last row of plug shielding contacts 40 to provide a shielding effect on all four sides of the signal pin 501 in the plug-in cavity 403. The function of the shielding tail plate 60 is to be used for shielding and conducting with the shielding tail claw 6. Specifically, the spring claw IV 61 of the shielding tail claw 6 abuts against one end face of the shielding tail plate 60 to achieve shielding and conducting.

[0042] In order to better guide the male connector 200 and the female connector 100 to be plugged in, a plug-in guide surface 703 is provided on the inner edge of the head end of the cavity 701 of the male end shell 70 to guide the male connector 200 to be connected to the female connector 100; the inner wall of the cavity 701 of the male end shell 70 and the outer wall of the insulating shell 7 of the female connector 100 are provided with a matching guide structure. A typical embodiment is used to illustrate that guide blocks 702 are provided on the inner walls of the opposite sides of the male end shell 70, and a guide groove 79 is provided on the insulating shell 7. The structure and size of the guide blocks 702 and the guide groove 79 are adapted to each other. In order to prevent mis-plugging, the misalignment, number, and width of the guide blocks 702 on both sides can be used to prevent mis-plugging. It should be noted that the corresponding number of guide blocks 702 and guide grooves 79 can be one or more.

[0043] When the curved male connector 200 is mated with the curved female connector 100, the outer mating bevel 742 of the curved female connector 100 guides the plug shield contact 40 into its internal slot 75, while the inner mating bevel 743 guides the signal pin 501 into connection with the signal plug 51. This structure reduces the difficulty of mating the curved male and female connectors and improves the reliability of the shielded mating connection between the two.
