[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 male connector, including a wafer contact component, a plug-in end common ground component 3, a plug shielding contact 4 and a positioning plate 6, with the plug-in end of the bent male connector 10 as its head end, and several groups of wafer contact components are arranged in parallel. Each group of wafer contact components includes an injection-molded component 1 and a shielding plate assembly 2. A differential signal pair 5 is arranged inside each injection-molded component 1. The differential signal pair 5 is used to realize the transmission of differential signals, and the shielding plate assemblies 2 located on both sides of the injection-molded component 1 are used to provide electromagnetic shielding for the signal transmission of the differential signal pair 5. The signal pin 51 of the differential signal pair 5 extends into the cavity of the plug shielding contact 4, and the tail end of the differential signal pair 5 is provided with a tail terminal 52 and passes through the positioning plate 6. The tail terminal 52 can adopt a fisheye terminal structure, etc. The positioning plate 6 is used to fix the wafer contact components, and the wafer contact components are arranged in sequence on the positioning plate 6.

[0024] In this embodiment, the plug-end common ground member 3 is mounted at the head end of the wafer contact component. In a typical embodiment of the present invention, the plug-end common ground member 3 is arranged in an array with a number of plug cavities 31 and plug tail cavities 32. The plug tail cavities 32 are located in the last row of the plug cavities 31. The rows and columns of the plug cavities 31 are arranged in a corresponding and neat manner. The plug cavities 31 are set through at both ends. Preferably, the plug cavities 31 in this solution have a square cavity structure. The plug cavities 31 are adapted to the external structure of the plug shielding contact 4. The tail ends of the plug shielding contacts 4 are inserted from the head end side of the plug cavities 31 and fixed inside the plug cavities 31. The outer wall of the plug-end common ground member 3 is provided with a plug card slot I 33 and a plug card slot II 34. The cross-sectional profile of the plug-in end common ground member 3 is square as a whole, and the plug-in card slot I33 is arranged on the two opposite end faces of the plug-in end common ground member 3. Preferably, the plug-in card slot I33 is arranged axially along the plug-in end common ground member 3 and does not pass through the entire outer wall surface, and is used to achieve stop cooperation with the insulating shell 7. The plug-in card slot II34 is arranged on the other two opposite end faces of the plug-in end common ground member 3, and preferably, the plug-in card slot II34 is arranged axially along the plug-in end common ground member 3 and passes through the entire outer wall surface.

[0025] This embodiment further includes an insulating housing 7, which includes an axially extending accommodating cavity 73. A stop block 72 is provided on the inner wall of the accommodating cavity 73, which engages with the plug-in card slot Ⅰ33 of the plug-in end common ground member 3. After the stop block 72 is engaged with the plug-in card slot Ⅰ33, it can abut against the rear end of the plug-in card slot Ⅰ33, thereby forming an axial limit stop between the insulating housing 7 and the plug-in end common ground member 3, thereby ensuring the installation position of the plug-in end common ground member 3 within the insulating housing 7, thereby further ensuring the accurate assembly position of the plug shielding contact 4 within the plug-in end common ground member 3. An insertion block 71 is also provided on the inner wall of the accommodating cavity 73, which engages with the plug-in card slot Ⅱ34 of the plug-in end common ground member 3. By adapting the plug-in card slot I 33 and the plug-in card slot II 34 to the card block structure on the inner wall of the accommodating cavity 73 of the external insulator shell 7, the fixing effect and assembly position accuracy of the plug-in end common ground component 3 and the insulator shell 7 can be achieved.

[0026] The structure of the plug shielding contact 4 is described below: In this solution, the plug shielding contact 4 includes a main shielding part 41 and a secondary shielding part 42, the main shielding part 41 includes a plug-in barrel 411, a shielding plate 413 and a spring arm 414, wherein the plug-in barrel 411 is a square cylindrical structure, and a shielding cavity 43 is arranged along the axial direction of the plug-in barrel 411, and a raised contact I412 for achieving card connection is arranged on the outer wall of the plug-in barrel 411, and the raised contact I412 is located on the four outer walls of the plug-in barrel 411, and is an outward-protruding bulge structure formed by the outer wall. Preferably, the raised contacts I412 on each side of the outer wall are set to two or more. As shown, the raised contacts I 412 can be arranged along the width of the plug shield contact 4 (the width direction is perpendicular to the insertion direction) as on side A, along the length of the plug shield contact 4 (the length direction is the insertion direction) as on side B, or in an array along both the length and width directions (an array refers to both the length and width directions) as on side C. The raised contacts I 412 are designed to achieve a tight fit with the plug cavity 31. The two side walls of the plug barrel 411 extend toward the same side to form a shielding plate 413. The two shielding plates 413 are arranged parallel to each other, and a snap-in gap 46 is formed between the two shielding plates 413. After the secondary shielding member 42 is inserted into the snap-in gap 46, elastic arms 414 are provided on the same side of the two shielding plates 413. The fixed ends of the two elastic arms 414 are connected to the corresponding positions of the two opposing shielding plates 413. The free ends of the two elastic arms 414 are tilted outward from the outside of the shielding plates 413, and the two elastic arms are tilted outward at the same angle, so that the two elastic arms 414 are arranged in a substantially symmetrical state. When free and unloaded, the elastic arms 414 protrude from the outer side of the shielding plate 413. The two opposing elastic arms 414 are used to press against the inner wall of the plug hole 1141 of the adapter bent female connector 11 in a direction away from each other after being compressed to achieve shielding conduction.

[0027] This solution achieves good electrical contact between the plug-end common ground member 3 and the plug shield contact 4 by providing a convex structure on the plug shield contact 4, and provides sufficient holding force. At the same time, since the plug shield contact 4 is provided as a split component in this solution, it is more convenient to produce and process, and can effectively ensure the processing accuracy of the component.

[0028] In this solution, the secondary shielding member 42 is inserted into the card-mounting gap 46. The secondary shielding member 42 is a sheet structure. The secondary shielding member 42 and the shielding plate 413 are arranged vertically. The plug shielding contact 4 head end has a C-shaped half-wrapped structure. The plug shielding contact 4 head end is not provided with a secondary shielding member 42 on the side of the gap 415. The gap 415 is provided with a shielding effect on this side by the adjacent plug shielding contact 4. The plug shielding contact 4 in the last row no longer has a plug shielding contact 4 to provide shielding cooperation at its rear end. Therefore, the plug shielding contact 4 in the last row is not provided with a shielding contact 4 at the rear end. A shielding tail plate 45 is provided on one side of the notch 415; the shielding tail plate 45 is combined with the last row of plug shielding contacts 4 to provide a shielding effect on all four sides of the signal pin 51 in the plug-in cavity 47. The shielding tail plate 45 is fixed in the plug-in tail cavity 32. The shielding tail plate 45 is provided with raised contacts IV 451 on both sides near the tail end, and is electrically contacted with the inner wall of the plug-in tail cavity 32 through the raised contacts IV 451. The purpose of setting the plug-in tail cavity 32 on the common ground component 3 of the plug-in end here is to install the shielding tail plate 45. The shielding tail plate 45 can extend into the plug-in tail cavity 32 and be fixed inside it.

[0029] In one embodiment of the present invention, the auxiliary shielding member 42 may adopt the following structure: for example, a raised contact II 421 is formed on the outer wall of the auxiliary shielding member 42, and the raised contact II 421 is a convex structure raised from the outer wall. The raised contact II 421 is located near the tail end of the auxiliary shielding member 42, and the raised contact II 421 on the outer wall is used to contact the inner wall of the plug-in cavity 31. The clamping surfaces on both sides of the auxiliary shielding member 41 are also provided with raised contacts III 422, and the auxiliary shielding member 41 is fixed in the clamping gap 46 by the raised contacts III 422. Preferably, the head end of the secondary shield 42 is flush with the head end of the shield plate 413, and chamfered corners 423 are formed on both sides of the head end of the secondary shield 42, thereby forming an escape gap 44 between the secondary shield 42 and the elastic arm 414. The function of the escape gap 44 is to allow the elastic arm 414 to move freely within a certain range after being subjected to force in the compressive direction, preventing the secondary shield 42 from obstructing the free movement of the elastic arm 414 to that side. To facilitate the assembly and fixation of the secondary shield 42 with the main shield 41, chamfered structures 424 are formed at the rear corners of the secondary shield 42. The chamfered structures 424 are used to prevent interference with the right-angle structure at the connection between the shield plate 413 and the plug-in barrel 411 during assembly.

[0030] In this embodiment, the head end of the plug shielding contact 4 is exposed from the plugging interface of the plug-end common ground member 3 and extends into the plugging cavity of the head end of the insulating outer shell 7, so as to be plugged into the socket shielding contact 113 of the adapter connector. It should be noted that the auxiliary shielding part 42 is exposed outward at the plug-in interface of the plug-in end common ground part 3. Since the head ends of the main shielding part 41 and the auxiliary shielding part 42 are flush, the tail end of the auxiliary shielding part 42 can be inserted into and fixed inside the plug-in cavity 31 of the plug-in end common ground part 3, so that the overall length dimension of the auxiliary shielding part 42 along the plug-in direction is greater than the length dimension of the exposed plug-in interface of the main shielding part 41 along the plug-in direction. By making one side of the auxiliary shielding part 42 contact with the plug connector 8, the other side is reliably contacted with the inner wall of one side of the plug-in cavity 31 of the plug-in end common ground part 3 through the protruding contact II 421, that is, the tail end of the auxiliary shielding part 42 is located in the plug-in cavity 31, and the auxiliary shielding part 31 abuts against the inner wall of the plug-in cavity 31 through the protruding contact II 421, so as to have sufficient holding force. The two narrow sides of the auxiliary shielding member 42 are in contact with the two opposite end surfaces of the shielding plate 413 , and the two narrow side notches 423 of the auxiliary shielding member 42 are correspondingly arranged with the two elastic arms 414 . Specifically, the auxiliary shielding member 42 can abut against the common ground member 3 of the plug-in end through the raised contact II 421 with sufficient holding force, and the auxiliary shielding member 42 can abut against the main shielding member 41 through the raised contact III 422 with sufficient holding force, thereby ensuring the reliability of electrical contact. At the same time, this solution separates the plug shielding contact 4 into two independent components, the main shielding member 41 and the auxiliary shielding member 42. On the one hand, it can facilitate mechanical processing, ensure the dimensional accuracy of the parts, and facilitate the processing of the elastic arm 414. In addition, due to the use of separate processing, the processing of the elastic arm 414 does not require the provision of a processing opening on one side of the elastic arm 414 as in the integrated structure. Therefore, after the separate shielding component of this solution is assembled into the plug shielding contact 4, it only needs to provide an avoidance gap 44 for the free movement of the elastic arm 414. Since the avoidance gap 44 is much smaller than the processing opening size required to be reserved during the mechanical processing of the elastic arm 414, the electromagnetic leakage gap of the plug shielding contact 4 in this solution is significantly reduced, thereby providing a better guarantee for the electromagnetic shielding effect.

[0031] In this embodiment, the injection molded component 1 is a contact component that is injected once. Each injection molded component 1 includes multiple differential signal pairs 5 for signal transmission. The head end of the differential signal pair 5 passes through the plug connector 8 and extends outward to form a signal pin 51. The tail end of the differential signal pair 5 is provided with a tail terminal 52 and can pass through the positioning plate 6. The plug connector 8 is an external square structure, which is adapted to the inner wall structure of the shielding cavity 43. The plug connector 8 penetrates into the shielding cavity 43 so that the signal pin 51 of the differential signal pair 5 is located inside the plug shielding contact 4. Shielding plate assemblies 2 are provided on both sides of the injection molded component 1. The structure of the shielding plate assembly 2 can adopt the following implementation mode. The shielding plate assembly 2 includes a first shielding plate 21 and a second shielding plate 22 respectively located on both sides of the injection molded component 1. The main bodies of the first shielding plate 21 and the second shielding plate 22 are both sheet-shaped. Structure, the first shielding piece 21 and the second shielding piece 22 are respectively arranged on both sides of the injection molded component 1, and the head ends of the first shielding piece 21 and the second shielding piece 22 are both provided with a connection structure that is electrically in contact with the plug shielding contact 4, and the head end of the first shielding piece 21 is provided with a contact claw 212, and the head end of the contact claw 212 is provided with an elastic claw, which can elastically contact the inner wall surface of the first side wall of the shielding cavity 43 of the plug shielding contact 4 (specifically, the inner wall of the first side wall refers to the inner wall of the shielding cavity 43 formed by the auxiliary shielding part 42), that is, the contact claw 212 applies a force to the inner wall of the shielding cavity 43 of the plug shielding contact 4 along the thickness direction of the shielding piece, as shown in the figure, and applies an interactive force with the plug shielding contact 4 along the D direction, and the tail ends of the first shielding piece 21 and the second shielding piece 22 can adopt fisheye terminals 23.

[0032] In this embodiment, a snap-fit ​​fixing portion I 211 is respectively provided on both sides of the contact claw 212. The snap-fit ​​fixing portion I 211 includes a first cantilever arm 2111 and a second cantilever arm 2112. The first cantilever arm 2111 and the second cantilever arm 2112 are arranged in parallel and are respectively located on both sides of the contact claw 212. The first cantilever arm 2111 and the second cantilever arm 2112 are both provided with signal contacts I 2113 that contact the inner walls on opposite sides of the shielding cavity 43. The signal contact I2113 of the first cantilever arm 2111 and the signal contact I2113 of the second cantilever arm 2112 are respectively electrically contacted with the inner wall surfaces on the opposite sides of the shielding cavity 43 (the inner wall surfaces of the second side wall), thereby achieving a tight fit between the single plug shielding contact 4 and the first shielding plate 21, ensuring the reliability of the electrical connection between the first shielding plate 21, the second shielding plate 22 and the plug shielding contact 4. The second side wall of the shielding cavity 43 is perpendicular to the first side wall. Specifically, the signal contact I2113 can adopt an arc-shaped protrusion structure as shown in the figure, and achieve a tight fit with the inner wall of the shielding cavity 43 of the plug shielding contact 4 through the vertex of the arc-shaped protrusion structure. The first shielding plate 21 fixes the plug shielding contact 4 from three directions through the contact claw 212, the first cantilever arm 2111, and the second cantilever arm 2112, so that the reliability of the contact between the first shielding plate 21 and the plug shielding contact 4 is improved.

[0033] In this embodiment, the tip of the second shielding plate 22 is provided with a snap-fitting portion II. This portion II extends into the gap 48 between two adjacent plug shielding contacts 4 and contacts the adjacent plug shielding contacts 4 on either side, thereby achieving electrical connection between the second shielding plate 22 and the plug shielding contacts 4 and ensuring reliable electrical contact between the two. The snap-fitting portion II includes a third cantilever arm 221, with paired signal contacts II 2211 formed on either side of the third cantilever arm 221. The third cantilever arm 221 extends into the gap 48 between the two adjacent plug shielding contacts 4, and the two signal contacts II 2211 are tightly fitted with the opposing outer walls of the two adjacent plug shielding contacts 4. With this design, the two shielding plates 2 on either side of this embodiment achieve fixed contact between a single plug shielding contact 4 and the shielding plate, respectively, through different snap-fitting structures. Furthermore, the snap-fitting structures also ensure reliable electrical connection between the plug shielding contacts 4 and the first and second shielding plates 21 and 22, respectively. This solution ensures shielding continuity through the contact points (signal contact I 2113 and signal contact II 2211) at the ends of the first shielding sheet 21 and the first shielding sheet 22. It should be noted that the third cantilever arm 221 contacts the outer wall of the second side wall of the plug shielding contact 4. The second side wall is the two side walls perpendicular to the first side wall. The first cantilever arm 2111, the second cantilever arm 2112, and the third cantilever arm 221 are respectively disposed on the inner and outer side surfaces of the second side wall and are in electrical contact therewith.

[0034] In this embodiment, both raised contact I 412 and raised contact II 421 are formed as raised bumps on the outer wall of the plug shield contact 4. The plug shield contact 4 contacts the metallized common ground grid of the mating end common ground component 3, ensuring electrical continuity across all metal plug shield contacts 4 on the connector, effectively improving signal transmission performance. After assembly, the differential pair pins (signal pins 51) are located within the mating cavity 47 of the plug shield contact 4, shielded on three sides by the shield plate 413 of the primary shield and the secondary shield 42. Simultaneously, the notch 415 of the plug shield contact 4 provides shielding for that side of the notch, provided by the adjacent pair of plug shield contacts 4 located on either side of the notch. This design ensures that each differential pair pin is shielded on all sides, improving transmission performance.

[0037] In this solution, side spring claws II 1133 are provided on both sides of the base of the receptacle shielding contact 113 near the tail end. These claws II 1133 are used to adapt to the inner wall of the plug hole 1141 of the plug-end common ground component 114, thereby achieving common ground conductivity for all receptacle shielding contacts 113. A connector 1134 is provided at the tail end of the base. Connector 1134 adapts and connects to the connecting hole at the head end of the shielding plate assembly 112, thereby achieving metal shielding conductivity between the shielding plate assembly 112 and the receptacle shielding contact 113. The plugging area of ​​the receptacle shielding contact 113 in this solution adopts an integrated design with three-sided spring claws, which can ensure the precision of part processing and reduce the difficulty of processing.
