[0057] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0058] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "a," "an," or "the," and similar words used in the specification and claims of this patent application do not express a limitation of quantity, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0059] As shown in the figure, this embodiment provides a right-angle female connector. The right-angle female connector 100 includes contact components and a mating end grounding component 3. The contact components include an injection-molded component 1, a shielding plate assembly 2, a socket shielding contact 4, and differential signal pairs 5. Each injection-molded component 1 has a differential signal pair 5 inside, which 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 opposing spring contacts assembled together, which are used to adapt the signal pin 501 of the right-angle male connector 200 to be inserted into the two spring contacts to achieve electrical connection. The tail end of the differential signal pair 5 is provided with a tail terminal 52 and passes through a positioning plate 8. The contact components are arranged sequentially on the positioning plate 8.

[0060] In this scheme, each socket shielding contact 4 is set independently, which enables the shielding contact structure to have a certain degree of self-adaptability and improves the reliability of shielding with the male connector 200. The structure of the socket shielding contact 4 is described below: The socket shielding contact 4 includes a base 41, a spring claw part 42 disposed at the head end of the base 41, and a connector head 44 disposed 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 plate 412 is perpendicular to the substrate 411 and has a rounded transition surface. The spring claw portion 42 includes spring claw I 421 and spring claw II 422, wherein spring claw II 422 is symmetrically arranged on both sides of spring claw I 421. Preferably, spring claw I 421 is provided with a row of several contact spring claws. The tail end of spring claw I 421 is connected to the substrate 411 and integrally formed. The head end of spring claw I 421 is a free end. The spring claw portion 42 is used to achieve shielded conduction with the plug shielding contact 40 of the adapter right-angle connector 200. The connector head 44 is formed by extending from the side plate 412 towards the tail end. The connector head 44 is used to achieve shielded conduction connection with the head end connection portion of the shielding sheet assembly 2. Spring claw III 43 is also provided on the side plates 412 on both sides of the base 41. Spring claw III 43 is provided outwardly from the base 41. Spring claw III 43 is used to make electrical contact with the inner wall of the insertion cavity 31 of the mating end grounding member 3. Specifically, the insertion cavity 31 has protrusions 33 on opposite sides near the tail end. The protrusions 33 can make electrical contact with the spring claw Ⅲ 43 and maintain a reliable contact state. In addition, the protrusions 33 can cooperate with the spring claw Ⅲ 43 to form an insertion gap between the two sides of the socket shielding contact 4 and the insertion cavity 31 for cooperating with the plug shielding contact 40 of the right-angle male connector 200. This insertion gap is connected to the corresponding slot 75. In this design, the length of the spring claw Ⅰ 421 in the insertion direction is greater than the length of the spring claw Ⅱ 422 in the insertion direction, so that the spring claw Ⅰ 421 can extend into the slot 75 on the periphery of the socket 74 and be placed in the receiving groove 744 on the outer wall of the socket 74. The receiving groove 744 is located on one side of the slot 75 and the two are connected. The spring claw II 422 does not extend into the slot 75. When the male and female right-angle connectors are inserted, guided by the slot 75, the spring claw II 422 makes contact with the shielded contact 40 of the plug of the matching male right-angle connector 200. Since the head of the spring claw II 422 is located at the tail end of the socket 74, the head of the spring claw II 422 will not directly collide with the shielded contact 40 of the plug of the male right-angle connector 200 during the insertion process, thus avoiding damage to the spring claw.

[0061] In this embodiment, the socket shielding contacts 4 are arranged neatly in rows and columns. A row of metal shielding claws 6 is provided on one side of the end of the array formed by the socket shielding contacts 4. The function of the shielding claws 6 is to cooperate with the shielding tail plate 60 of the adapter right-angle connector 200. The structure of the shielding claws 6 is described below: There are several shielding claws 6 arranged in a row. The head end of the shielding claw 6 is provided with a spring claw IV 61 and the tail end is provided with a clamping arm 63. The two clamping arms 63 are arranged opposite each other and pass through the slot 11 of the injection molded part 1 to make electrical contact with the end face of the shielding sheet assembly 2. The opposite side of the clamping arm 63 is provided with a raised contact II 64. The raised contact II 64 is used to make electrical contact with the end faces of the shielding sheet I 21 and the shielding sheet II 22. The end face of the middle section of the base plate of the shielding claw 6 is provided with a protrusion 62 that abuts against one side of the inner wall of the slot 11.

[0062] In this embodiment, the socket shielding contact 4 is made into a C-shaped structure, so that elastic contact points extend from its front and two sides in three directions to make contact with the metal shield (plug shielding contact 40) on the matching male connector 200, thereby increasing the electromagnetic shielding effect. Lateral contact points extend from both sides of the base 41 to make electrical contact with the mating end grounding member 3. With this design, all socket shielding contacts 4 are grounded and connected. The connectors 44 on both sides of each socket shielding contact 4 are shielded and connected to the shielding plates I 21 and II 22 on both sides of the injection molded part 1.

[0063] The structure of the contact component is described below: The injection-molded component 1 is a contact component produced in a single injection. Each injection-molded component 1 contains multiple differential signal pairs 5 for signal transmission. The head end of each differential signal pair 5 forms a signal insert 51, which consists of two opposing spring tabs. The gap between the two spring tabs is used to accommodate the insertion of the signal pin 501 of the right-angle connector 200. The tail end of the differential signal pair 5 is provided with a tail terminal (e.g., a fisheye terminal) 52, which can pass through the positioning plate 8. Shielding sheet assemblies 2 are provided on both sides of the injection-molded component 1.

[0064] The shielding assembly 2 can be implemented as follows: The shielding assembly 2 includes shielding sheet I 21 and shielding sheet II 22, wherein shielding sheet I 21 and shielding sheet II 22 are respectively disposed on two opposite end faces of the injection molding component 1, and are used to provide electromagnetic shielding for the differential signal pair 5 within the injection molding component 1. The head ends of shielding sheet I 21 and shielding sheet II 22 are each provided with a connecting portion for electrical contact with the socket shielding contact 4. The connecting portion includes connecting piece I 23 and connecting piece II 24. The function of connecting piece I 23 is to connect to the tail end connector 44 of the socket shielding contact 4. Preferably, connecting piece I 23 is perpendicular to the main bodies of shielding sheet I 21 and shielding sheet II 22, respectively, and a hole I 231 is formed on connecting piece I 23. Hole I 231 is used for electrical connection with the tail end of the socket shielding contact 4. Specifically, the tail end of the socket shielding contact 4 is provided with a connector 44, which has a hole II 441. The connector 44 is inserted into the hole I 231 to achieve electrical connection. The hole II 441 allows the connector 44 to retract into the hole II 441 when the two metal parts, connector 44 and connector I 23, are engaged, thus giving it a certain amount of deformation. Connector I 23 can be formed by bending from the shielding plate body away from its corresponding injection molded part 1. Connector I 23 and connector II 24 are arranged alternately and perpendicular to each other, so that after installation, connector I 23 can cover the opening at the tail end of the socket shielding contact 4, preventing the tail end of the socket shielding contact 4 from being exposed, thereby achieving a better electromagnetic shielding effect. At the same time, the perpendicular arrangement of connector I 23 and connector II 24, with the interference contact using a line and surface fit, facilitates the installation and positioning of the socket shielding contact 4. The connecting piece II 24 can be formed by extending the shielding sheet body towards the head end. The narrow side of the connecting piece II 24 has a raised contact I 241 that can make electrical contact with the end face of the substrate 411 of the socket shielding contact 4.

[0065] In a typical embodiment of the present invention, the insulating shell 7 includes an outer frame 71, the interior of which is divided into cavities by an inner partition 72. Each cavity is provided with a plurality of insertion sockets 74. Specifically, after the outer frame 71 is divided into cavities by the inner partition 72, a positioning guide post 76 is provided perpendicular to the inner partition 72 in each cavity. The positioning guide post 76 divides the cavity into independent insertion cavities. An insertion socket 74 is provided on the inner partition 72 of each insertion cavity. One side of the insertion socket 74 is fixed to the inner partition 72, and the other three sides of the insertion socket 74 are connected to the adjacent inner partition 72 and the positioning guide post 76. A C-shaped slot 75 is formed between the outermost socket 74 and the other three sides of the outermost socket 74 form a C-shaped slot 75 with the adjacent inner partition 72, positioning guide post 76 and outer frame 71. The slot 75 is arranged through the insertion 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 grooves 77 is provided at the end of the insertion cavity 31. The head end of the shielding claw 6 is provided in the tail groove 77. The shielding tail plate 60 of the bent male connector 200 is inserted into the tail groove 77 to realize the shielding conduction of the shielding claw 6 and the shielding tail plate 60.

[0066] As shown in the figure, the socket 74 has sockets 741 along the insertion direction. Preferably, the sockets 741 are arranged in pairs along the insertion direction, and are separated by a spacer 747. The sockets 741 are used for the pins of the differential signal pair 50 of the right-hand male connector 200 to pass through and extend into the signal plug 51 to achieve signal connection. An outer insertion bevel 742 is formed at the edge of the socket 74 near the slot 75. The outer insertion bevel 742 is used to guide the plug shielding contact 40 of the right-hand male connector 200 to be inserted. An inner insertion bevel 743 is formed at the edge of the socket 74 near the socket 741. The inner insertion bevel 743 is used to guide the signal pins 501 of the right-hand male connector 200 to be inserted. The socket 74 has a receiving groove 744 on the side opposite to the inner partition 72 it is connected to. The receiving groove 744 is used to accommodate the spring claw I 421, so that the head end of the spring claw I 421 is placed in the receiving groove 744. In order to allow the spring claw I 421 to elastically deform and avoid, the bottom of the receiving groove 744 is provided with a relief slope. Support guide blocks 746 are provided on both sides of the receiving groove 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 post 76 is described below. The head end of the positioning guide post 76 is provided with a mating surface 761 on both sides. The mating surface 761 includes a slope located at the opening of the slot 75 on both sides. The mating surface 761 is used to guide the plug shield contact 40 of the right-angle male connector 200 into the slot 75. The tail end of the positioning guide post 76 has a stop positioning surface 762, which is used to cooperate with the mating end common part 3 for stop positioning.

[0067] In this embodiment, the signal plug 51 at the head end of the differential signal pair 5 corresponds to the two sockets 741 of the socket 74, and an isolation block 745 is provided on the inner wall of the side of the two sockets 741 that are far apart. The function of the isolation block 745 is to position and separate the two springs of the signal plug 51, so as to reduce the insertion force when the signal pin 501 of the adapter connector enters between the two springs of the corresponding signal plug 51 to achieve electrical connection.

[0068] The structure of the mating end grounding member 3 is described below: The mating end grounding member 3 has mating cavities 31 arranged in an array along the upper edge. The function of the mating cavity 31 is to install the socket shielding contact 4 and make electrical contact with the socket shielding contact 4. The mating cavity 31 is divided into independent square mating cavities 31 by horizontal and vertical plates. The horizontal or vertical plate extends to one end to form a positioning plate 32. The function of the positioning plate 32 is to be able to be inserted between two adjacent inner partitions 72 from the tail end of the insulating shell 7, and the positioning plate 32 can abut against the stop positioning surface 762 of the positioning guide post 76 to limit the relative position of the mating end grounding member 3 and the insulating shell 7 along the axial direction (mating direction).

[0069] In order to achieve the connection between the insulating shell 7, the mating end grounding component 3 and the injection molded component 1, the insulating shell 7 is provided with a slot or hole 78, and the injection molded component 1 is provided with a locking block I 12 on both sides. The mating end grounding component 3 is also provided with a locking block II 34 on its periphery. The locking block I 12 of the injection molded component 1 and the locking block II 34 of the mating end grounding component 3 respectively cooperate with the corresponding locking hole 71 of the insulating shell 7, thereby realizing the assembly of the above components.

[0070] In the above structure of this solution, shielding sheet I 21 and shielding sheet II 22 are respectively provided on both sides of the injection molded component 1. Then, a socket shielding contact 4 is connected to one side of the head end of shielding sheet I 21 and shielding sheet II 22, so that the above component and the socket shielding contact 4 are assembled to form a complete contact component, which facilitates the assembly of subsequent processes. Then, the above contact component is assembled with the mating end grounding component 3 and the insulating shell 7, thereby optimizing the sequence of automated assembly and greatly improving the assembly yield and assembly efficiency.

[0071] This solution also provides a connector assembly, including the aforementioned bent female connector 100 and a mating bent male connector 200.

[0072] To make the principle of this solution clearer, the structure of the right-angle male connector 200 adapted to the right-angle female connector 100 in this solution is described below: The head end of the right-angle male connector 200 (the mating end that mates with the right-angle female connector 100 is its head end) mates with the head end of the right-angle female connector 100 to achieve mating mating. Specifically, the right-angle male connector 200 includes an adapter contact component, a plug shield contact 40, an adapter mating end grounding component 30, and a male end housing 70. The plug shield contact 40 includes a detachably connected main shield 401 and a secondary shield 402. 1 includes a plug-in barrel 4011, a shielding plate 4013, and a spring arm 4014. The plug-in barrel 4011 is a square cylindrical structure with a shielding cavity along its axial direction. The outer side wall of the plug-in barrel 4011 is provided with raised contact points III for snap-fit. The raised contact points III are located on the four outer side walls of the plug-in barrel 4011 and are outwardly protruding ridges formed by its outer side walls. They are used for electrical contact between the plug shielding contact 40 and the adapter mating end grounding member 30. The plug-in barrel 4011 is fixed in the plug slot 301 of the adapter mating end grounding member 30 through the raised contact points III. The two opposite side walls of the plug-in barrel 4011 extend towards the head end to form shielding plates 4013. The two shielding plates 4013 are arranged parallel to each other, and a snap-fit ​​gap is formed between the two shielding plates 4013. The secondary shielding member 402 is inserted into the snap-fit ​​gap and fixed. On the same side of the two shielding plates 4013, there are outwardly tilted spring arms 4014. The spring arms 4014 are located on both sides of the secondary shielding member 402, and the fixed end of the spring arm 4014 is connected to the shielding plate 4013. When the free end of the spring arm 4014 is in a free state without force, it protrudes from the outer side of the shielding plate 4013. A movable gap is reserved between the spring arm 4014 and the secondary shielding member 402 for the spring arm 4014 to be pressed. When the bent female connector 100 and the bent male connector 200 are plugged in, the two opposite spring arms 4014 are used to abut against the inner wall of the plug cavity 31 of the grounding member 3 of the mating end of the bent female connector 100 after being pressed. Specifically, the two opposing spring arms 4014 are located at the corresponding positions of the shielding plate 4013 and are arranged symmetrically to each other.

[0073] In this design, the adapter contact components of the male-to-female connector 200 include a male injection-molded component 10 and a male shielding plate assembly 20. The male shielding plate assembly 20 includes a first shielding plate and a second shielding plate disposed opposite to each other on both sides of the male injection-molded component 10. Each male injection-molded component 10 contains a differential signal pair 50 for differential signal transmission. The first shielding plate and the second shielding plate are respectively shielded and conductively connected to the tail end shielding of the plug shielding contact 40. The first shielding plate has a contact claw, a first cantilever arm, and a second cantilever arm at its head end. The contact claw, the first cantilever arm, and the second cantilever arm extend into the plug shielding contact 40 insertion barrel 4011 and contact the inner walls of the insertion barrel 4011 on three sides respectively. Specifically, the contact claw contacts one inner wall of the insertion barrel 4011 along the thickness direction of the shielding plate, and the first and second cantilever arms contact the other two opposite inner walls of the insertion barrel 4011 along the width direction of the shielding plate. These two opposite inner walls are perpendicular to the inner wall contacted by the contact claw. This achieves fixation of the plug shielding contact 4 from three directions, thereby improving the reliability of the contact between the first shielding plate and the plug shielding contact 4. The second shielding plate is provided with a third cantilever arm at its head end. 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 contacted by the first cantilever arm and the second cantilever arm.

[0074] In this design, a raised contact IV is formed on the outer wall of the sub-shielding component 402. The raised contact IV is a convex structure that rises from the outer wall. The raised contact IV is located near the tail end of the sub-shielding component 102. The raised contact IV on the outer wall is used to contact the inner wall of the insertion slot 301 of the grounding component 30 of the mating end. The two sides of the sub-shielding component 402 are also provided with raised contacts V. The sub-shielding component 402 is fixed in the gap between the two shielding plates 4013 by the raised contacts V.

[0075] In this design, both raised contact III and raised contact IV are raised convex structures. The plug shielding contact 40 makes electrical contact with the grounding component 30 of the mating end, enabling all metal plug shielding contacts 40 on the connector to be electrically conductive, thereby effectively improving signal transmission performance. The signal pins 501 (pins) at the male differential signal pair 50 are located inside the mating cavity 403 of the plug shielding contact 40 after assembly. They are shielded by the shielding plate 4013 of the main shielding component 401 and the secondary shielding component 402 on three sides. At the same time, the notch 4015 at the head end of the plug shielding contact 40 provides shielding to the pins on that side through the adjacent plug shielding contact 40 on one side of the notch 4015. This design enables shielding of each differential pair pin on all four sides, thereby improving transmission performance.

[0076] In this embodiment, the head end of the plug shielding contact 40 is exposed outward from the mating interface of the adapter mating end grounding member 30 and extends into the adapter insulating shell 70. When the male bend connector 200 and the female bend connector 100 are inserted into the socket, the signal pin 501 of the male terminal signal differential pair 50 of the male bend connector 200 extends into the signal plug 51 of the differential signal pair 5 of the female bend connector 100 to achieve electrical connection. Meanwhile, the plug shielding contact 40 extends into the slot 75 of the female bend connector 100 and achieves shielded conduction with the socket shielding contact 4. Specifically, the spring claws I 421 and II 422 of the socket shielding contact 4 are placed inside the plug shielding contact 40. The spring claw I 421 is electrically in contact with the end face of the secondary shield 402, and the spring claw II 422 is electrically in contact with the end face of the shielding plate 4013, thereby achieving shielded conduction between the male bend connector 200 and the female bend connector 100. In addition, the spring arm 4014 passes through the slot 75 and is shielded and connected to the inner wall of the insertion cavity 31 of the mating end grounding member 3 of the female bend connector 100.

[0077] The male-female connector 200 is also provided with a shielding tail plate 60. Specifically, the 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 and the last row of plug shielding contacts 40 provide shielding on all four sides of the signal pins 501 in the mating cavity 403. The function of the shielding tail plate 60 is to provide shielding and conduction with the shielding tail claw 6. Specifically, the spring claw IV 61 of the shielding tail claw 6 abuts against one side end face of the shielding tail plate 60 to achieve shielding and conduction.

[0078] To better guide the insertion of the male bend connector 200 and the female bend connector 100, a ring of insertion guide surfaces 703 is provided circumferentially on the inner edge of the cavity 701 of the male end housing 70 to guide the male bend connector 200 to mate with the female bend connector 100. The inner wall of the cavity 701 of the male end housing 70 and the outer wall of the insulating shell 7 of the female bend connector 100 are provided with matching guide structures. In a typical embodiment, guide blocks 702 are provided on the inner walls of opposite sides of the male end housing 70, and guide grooves 79 are provided on the insulating shell 7. The structure and size of the guide blocks 702 and the guide grooves 79 are adapted to each other. To prevent mis-insertion, the staggered arrangement, quantity, and width of the guide blocks 702 on both sides can be used to prevent mis-insertion. It should be noted that the corresponding number of guide blocks 702 and guide grooves 79 can be one or more each.

[0079] When the male bend connector 200 and the female bend connector 100 are mated together, the outer bend 742 of the female bend connector 100 guides the shielded contact 40 of the plug into its internal slot 75, and the inner bend 743 guides the signal pin 501 into the signal plug 51 to achieve connection. This structure helps to reduce the mating difficulty of the male bend connector and the female bend connector and improves the reliability of the shielded mating.
