[0002] With the development of technology, signal transmission rates are getting higher and higher, reaching as high as 112Gbps per channel. This requires hardware transmission links to support high-speed signal transmission, and connectors, as part of the link, must meet the transmission performance requirements.

[0003] To meet transmission performance requirements, a fully shielded structure is needed for differential signal transmission. Especially after the male and female connectors are mated, the signal pins are completely surrounded by a metal shield to prevent signal interference between differential pairs and thus avoid performance degradation.

[0008] As a preferred embodiment, the head end of the second shielding sheet is provided with a snap-fit ​​fixing component II. The snap-fit ​​fixing component II includes a third cantilever arm. Signal contacts II are respectively provided on opposite sides of the third cantilever arm. The third cantilever arm extends into the gap between two adjacent plug shielding contacts, and the signal contacts II abut against the outer walls of the two adjacent plug shielding contacts respectively.

[0009] As a preferred embodiment, the plug shielding contact includes a main shield and a secondary shield, wherein the secondary shield is detachably mounted on the main shield.

[0010] As a preferred embodiment, the main shielding component includes a plug barrel for mating with the plug cavity of the plug end grounding component and a shielding plate. The outer surface of the plug barrel is formed with a raised contact I, and the raised contact I abuts against the inner wall of the plug cavity. The shielding plate extends from both sides of the plug-in barrel end, and a snap-fit ​​gap is formed between the shielding plates to cooperate with the sub-shielding component.

[0011] As a preferred embodiment, both shielding plates are provided with spring arms, one end of which is connected to the shielding plate and the other end of which is tilted outward from the shielding plate, and the spring arms of the two shielding plates are arranged opposite to each other.

[0012] As a preferred embodiment, the secondary shield is located within the mounting gap, and the secondary shield and the shielding plate form a semi-enclosed mating cavity; the mating cavity is used to mate with the socket shielding contact of another compatible connector to achieve electrical conduction.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects: This solution employs a structural improvement, separating the plug shielding contact from the shielding plate. This avoids the risks of insufficient space for single-layer shielding or unreliable contact in double-layer shielding. Furthermore, the split structure of the plug shielding contact facilitates component manufacturing, ensures the precision of individual components, and guarantees high yield rates during assembly. The plug shielding contact is mounted from the head end of the mating end grounding component, while the shielding plate is mounted from the tail end, preventing damage to the contact springs on the plug shielding contact. This semi-enclosed metal plug shielding contact effectively reduces the footprint of the differential pair and the overall connector size. The split design of the plug shielding contact facilitates manufacturing and reduces electromagnetic leakage gaps, thereby ensuring higher and better transmission rates and performance.

[0021] 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.

[0022] 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.

[0023] As shown in the figure, this embodiment provides a right-angle male connector, including a wafer contact component, a mating end grounding component 3, a plug shielding contact 4, and a positioning plate 6. Taking the mating end of the right-angle male connector 10 as its head end, several groups of wafer contact components are arranged side by side. Each group of wafer contact components includes an injection molded component 1 and a shielding plate assembly 2. Each injection molded component 1 is provided with a differential signal pair 5, which is used to realize the transmission of differential signals. The shielding plate assembly 2 located on both sides of the injection molded component 1 is 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. 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 arrangement of the wafer contact components, and the wafer contact components are arranged sequentially on the positioning plate 6.

[0024] In this embodiment, the mating end grounding member 3 is installed at the head end of the wafer contact component. In a typical embodiment of the present invention, the mating end grounding member 3 has several mating cavities 31 and mating tail cavities 32 arranged in an array. The mating tail cavity 32 is located in the last column of the mating cavities 31. The rows and columns of the mating cavities 31 are arranged in a neat and symmetrical manner. The mating cavities 31 are through-holes at both ends. Preferably, the mating cavities 31 in this solution have a square cavity structure. The mating cavities 31 are adapted to the shape and structure of the plug shielding contact 4. The tail end of the plug shielding contact 4 is inserted into and fixed inside the mating cavity 31 from the head end side. The outer wall of the plug end grounding member 3 is provided with mating slot I 33 and mating slot II 34. The cross-sectional profile of the mating end grounding member 3 is generally square. The mating slot I 33 is provided on two opposite end faces of the mating end grounding member 3. Preferably, the mating slot I 33 is arranged along the axial direction of the mating end grounding member 3 and does not penetrate the entire outer wall surface, and is used to achieve a stop fit with the insulating shell 7. The mating slot II 34 is provided on the other two opposite end faces of the mating end grounding member 3. Preferably, the mating slot II 34 is arranged along the axial direction of the mating end grounding member 3 and penetrates the entire outer wall surface.

[0025] This solution also includes an insulating shell 7, which includes an axially extending receiving cavity 73. The inner wall of the receiving cavity 73 is provided with a stop block 72 that engages with the insertion slot I 33 of the mating end grounding component 3. After the stop block 72 is engaged with the insertion slot I 33, the stop block 72 abuts against the tail of the insertion slot I 33, creating an axial limiting and stopping effect between the insulating shell 7 and the mating end grounding component 3. This ensures the installation position of the mating end grounding component 3 within the insulating shell 7, further guaranteeing the precise assembly position of the plug shielding contact 4 within the mating end grounding component 3. An insertion block 71 is also provided on the inner wall of the receiving cavity 73, and the insertion block 71 engages with the insertion slot II 34 of the mating end grounding component 3. By adapting the insertion slots I33 and II34 to the locking block structure on the inner wall of the receiving cavity 73 of the outer insulating shell 7, the fixing effect and assembly position accuracy of the insertion end grounding component 3 and the insulating 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 shield 41 and a secondary shield 42. The main shield 41 includes a plug barrel 411, a shielding plate 413, and a spring arm 414. The plug barrel 411 is a square cylindrical structure. A shielding cavity 43 is provided along the axial direction of the plug barrel 411. The outer side wall of the plug barrel 411 is provided with raised contact I 412 for snap-fit. The raised contact I 412 is located on the four outer side walls of the plug barrel 411 and is an outwardly protruding structure formed by the outer side wall. Preferably, there are two or more raised contact I 412 on each outer side wall. As shown in the figure, the raised contact I 412 can be arranged along the width direction of the plug shield contact 4 (the width direction is perpendicular to the insertion direction) as on side A, or along the length direction of the plug shield contact 4 (the length direction is the insertion direction) as on side B, or in an array pattern along both the length and width directions as on side C (an array pattern means simultaneously along both the length and width directions). The raised contact I 412 is used to achieve a tight fit with the insertion cavity 31. The two side walls of the plug-in barrel 411 extend to the same side to form shielding plates 413. The two shielding plates 413 are arranged parallel to each other, and a locking gap 46 is formed between the two shielding plates 413. After the secondary shielding member 42 is inserted into the locking gap 46, spring arms 414 are provided on the same side of the two shielding plates 413. The fixed ends of the two spring arms 414 are connected to the corresponding positions of the two opposing shielding plates 413. The free ends of the two spring arms 414 are tilted outwards from the shielding plates 413, and the two spring arms tilt outwards at the same angle. The two spring arms 414 are arranged in a basically symmetrical state. In the free state without force, the spring arms 414 protrude from the outer side of the shielding plate 413. The two opposing spring arms 414 are used to abut against the inner wall of the plug hole 1141 of the adapter elbow connector 11 in a direction away from each other after being pressed, so as to achieve shielding and conduction.

[0027] This solution achieves good electrical contact between the grounding component 3 and the plug shielding contact 4 by setting a convex structure on the plug shielding contact 4, and provides sufficient holding force. At the same time, since the plug shielding contact 4 is set as a split component in this solution, it is easier to manufacture and process, and can effectively ensure the processing accuracy of the component.

[0028] In this design, the secondary shield 42 is inserted into the mounting gap 46. The secondary shield 42 has a sheet-like structure and is perpendicular to the shielding plate 413. The mating cavity 47 at the head end of the plug shield contact 4 has a C-shaped semi-enclosed structure. A notch 415 is formed on the side of the head end of the plug shield contact 4 where the secondary shield 42 is not located. The shielding effect on that side is provided by the adjacent plug shield contact 4 at the notch 415. Since the plug shield contact 4 in the last row no longer has a plug shield contact 4 providing shielding, the last row of plug shield contacts 4... A shielding tail plate 45 is provided on one side of the notch 415; the shielding tail plate 45, together with the last row of plug shielding contacts 4, provides shielding on all four sides of the signal pins 51 in the mating cavity 47. The shielding tail plate 45 is fixed in the mating cavity 32. The shielding tail plate 45 has raised contacts IV 451 on both sides near the tail end. The raised contacts IV 451 make electrical contact with the inner wall of the mating cavity 32. The purpose of the mating cavity 32 on the mating end grounding member 3 is to install the shielding tail plate 45. The shielding tail plate 45 can extend into the mating cavity 32 and be fixed inside it.

[0029] In one embodiment of the present invention, the sub-shielding member 42 may adopt the following structure: for example, a raised contact II 421 is formed on the outer side wall of the sub-shielding member 42. 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 sub-shielding member 42. The raised contact II 421 on the outer side wall is used to contact the inner wall of the insertion cavity 31. The two sides of the sub-shielding member 41 are also provided with raised contacts III 422. The sub-shielding member 41 is fixed in the mounting 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 shielding plate 413, and the head end of the secondary shield 42 has beveled corners 423 on both sides, which are used to form a clearance gap 44 between the secondary shield 42 and the spring arm 414. The clearance gap 44 allows the spring arm 414 to move freely within a certain range after being subjected to force in the compression direction, preventing the secondary shield 42 from obstructing the free movement of the spring arm 414 in that direction. To facilitate the assembly and fixation of the secondary shield 42 and the main shield 41, a chamfered structure 424 is formed at the tail corner of the secondary shield 42. The chamfered structure 424 is used to avoid interference when assembling the right-angle structure at the connection between the shielding plate 413 and the plug-in barrel 411.

[0030] In this design, the head end of the plug shielding contact 4 protrudes outward from the mating interface of the mating end grounding member 3 and extends into the mating cavity of the head end of the insulating housing 7. This is for mating contact with the socket shielding contact 113 of the adapter connector. It should be noted that the secondary shield 42 is exposed outward at the mating interface of the mating end common ground member 3. Since the head ends of the main shield 41 and the secondary shield 42 are flush, the tail end of the secondary shield 42 can be inserted into and fixed inside the mating cavity 31 of the mating end common ground member 3. This makes the overall length of the secondary shield 42 along the mating direction greater than the length of the main shield 41 exposed at the mating interface along the mating direction. By making one side of the secondary shield 42 contact the connector 8, and the other side reliably contact the inner wall of one side of the mating cavity 31 of the mating end common ground member 3 through the raised contact II 421, that is, the tail end of the secondary shield 42 is located inside the mating cavity 31, and the secondary shield 31 abuts against the inner wall of the mating cavity 31 through the raised contact II 421, thus having sufficient holding force. The two narrow sides of the secondary shield 42 are in contact with the opposite end faces of the shield 413, and the two narrow side notches 423 of the secondary shield 42 are correspondingly provided with the two side spring arms 414. Specifically, the secondary shield 42 has sufficient holding force to abut against the grounding member 3 at the mating end through the raised contact II 421, and sufficient holding force to abut against the main shield 41 through the raised contact III 422, 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 shield 41 and the secondary shield 42. On the one hand, this facilitates machining, ensures the dimensional accuracy of the parts, and is beneficial for the machining of the spring arm 414. On the other hand, due to the separate machining, the machining of the spring arm 414 does not require a machining process port on one side of the spring arm 414 as in the integrated structure. Thus, after the separate shielding components of this solution are assembled into the plug shielding contact 4, only a clearance gap 44 for the free movement of the spring arm 414 needs to be set. Since the clearance gap 44 is much smaller than the machining process port size required during the machining of the spring 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 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 connector 8 has an external square structure that adapts to the inner wall structure of the shielding cavity 43. The connector 8 is inserted 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 sheet assemblies 2 are provided on both sides of the injection-molded component 1. The structure of the shielding sheet assembly 2 can be implemented as follows: the shielding sheet assembly 2 includes a first shielding sheet 21 and a second shielding sheet 22 located on both sides of the injection-molded component 1. The main body of the first shielding sheet 21 and the second shielding sheet 22 are both sheet-like. The structure includes a first shielding plate 21 and a second shielding plate 22 respectively attached to both sides of the injection-molded component 1. The head ends of the first shielding plate 21 and the second shielding plate 22 are provided with a connection structure that makes electrical contact with the plug shielding contact 4. The head end of the first shielding plate 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 secondary shielding component 42). That is, the contact claw 212 applies a force to the inner side wall of the shielding cavity 43 of the plug shielding contact 4 along the thickness direction of the shielding plate, as shown in the figure, and applies an interaction force to the plug shielding contact 4 along the D direction. The tail ends of the first shielding plate 21 and the second shielding plate 22 can be fisheye terminals 23.

[0032] In this embodiment, a locking and fixing part I211 is provided on both sides of the contact claw 212. The locking and fixing part I211 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 located on both sides of the contact claw 212. Signal contacts I2113 that contact the inner walls of the shielding cavity 43 on both sides are provided on the first cantilever arm 2111 and the second cantilever arm 2112. The signal contacts I2113 of the first cantilever arm 2111 and the second cantilever arm 2112 make electrical contact with the inner walls of the shielding cavity 43 on both sides (the inner walls of the second sidewall), respectively, 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 sidewall of the shielding cavity 43 is perpendicular to the first sidewall. Specifically, the signal contact I2113 can adopt an arc-shaped protrusion structure as shown in the figure. The apex of the arc-shaped protrusion structure makes a tight fit with the inner wall of the shielding cavity 43 of the plug shielding contact 4. The first shielding plate 21 is fixed to the plug shielding contact 4 from three directions by the contact claw 212, the first cantilever arm 2111, and the second cantilever arm 2112, respectively, thereby improving the reliability of the contact between the first shielding plate 21 and the plug shielding contact 4.

[0033] In this design, the head end of the second shielding plate 22 is provided with a snap-fit ​​fixing part II. The snap-fit ​​fixing part II extends into the gap 48 between two adjacent plug shielding contacts 4, and contacts the adjacent plug shielding contacts 4 on both sides respectively. This is used to realize the electrical connection between the second shielding plate 22 and the plug shielding contacts 4, and to ensure the reliability of the electrical contact between the two. The snap-fit ​​fixing part II includes a third cantilever arm 221, and a pair of signal contacts II 2211 are formed on both sides of the third cantilever arm 221. The third cantilever arm 221 extends into the gap 48 between two adjacent plug shielding contacts 4, and the two signal contacts II 2211 are tightly fitted with the opposite outer walls of the two adjacent plug shielding contacts 4 respectively. With this design, the shielding plates 2 on both sides of this design achieve a fixed contact effect between a single plug shielding contact 4 and the shielding plate through different snap-fit ​​fixing structures. At the same time, the snap-fit ​​fixing structures also realize the reliable electrical connection between the plug shielding contacts 4 and the first shielding plate 21 and the second shielding plate 22 respectively. This solution ensures the continuity of shielding through the contact points (signal contact I 2113, signal contact II 2211) at the ends of the first shielding plate 21 and the first shielding plate 22. It should be noted that the third cantilever arm 221 contacts the outer wall of the second sidewall of the plug shielding contact 4. The second sidewall consists of two sidewalls perpendicular to the first sidewall. The first cantilever arm 2111, the second cantilever arm 2112, and the third cantilever arm 221 are respectively disposed on the inner and outer sides of the second sidewall and are in electrical contact with it.

[0034] In this embodiment, both raised contact I 412 and raised contact II 421 are raised bulge structures formed by the outer wall of the plug shield contact 4. The plug shield contact 4 contacts the metallized ground network of the mating end grounding member 3, making all the metal plug shield contacts 4 on the connector electrically conductive, thereby effectively improving signal transmission performance. The pins (signal pins 51) at the differential pair plug end are located inside the mating cavity 47 of the plug shield contact 4 after assembly, so that they are shielded and wrapped by the shielding plate 413 of the main shielding member and the three sides of the secondary shielding member 42. At the same time, the notch 415 of the plug shield contact 4 provides shielding for the pins on that side through the adjacent plug shield contact 4 on one side of the notch 415. This design can achieve shielding around each differential pair pin, thereby improving transmission performance.

[0035] In this solution, a spring arm 414 is provided on one side of the front end of the shielding plate 413. The function of the spring arm 414 is to enable the plug shielding contact 4 to make electrical contact with the socket shielding contact 113 of the other female connector 11 when the male and female connectors are mated, thereby achieving the continuity of the shielding effect.

[0036] To better illustrate the structural principle of this solution, the structure of the bend female connector adapted to the bend male connector of this solution is described below: The head end of the bend female connector 11 extends into the receiving cavity 73 of the bend male connector 10 to achieve insertion, as shown below. Figure 19-24As shown, the right-angle female connector 11 includes contact components, an adapter mating end grounding component 114, a positioning plate 116, and an adapter insulating shell 117. The contact components are arranged in parallel on the positioning plate 116. The adapter insulating shell 117 is located on the mating end side of the adapter mating end grounding component 114. The contact components include an injection-molded component 111 and shielding sheet assemblies 112 disposed on both sides of the injection-molded component 111. A differential signal pair 115 is disposed within the injection-molded component 111. The head end of the differential signal pair 115 is provided with a signal socket 1151, which is surrounded by several contact springs for mating with the signal pin 51 of the right-angle male connector 10. Taking a device with two contact springs as an example, the signal socket is composed of two contact springs, and a gap is formed between the two contact springs to accommodate the signal pin 51. The tail end of the differential signal pair 115 is provided with a terminal structure. The structure can adopt a fisheye terminal structure, etc. The shielding plate assembly 112 of the bent female connector 11 is provided with a socket shielding contact 113 on one side of the head end. The socket shielding contacts 113 are designed independently. The socket shielding contacts 113 are all located in the distributed plug holes 1141 of the adapter mating end grounding member 114. The adapter insulating shell 117 is installed on one side of the head end of the adapter mating end grounding member 114. The mating end face of the adapter insulating shell 117 has a plug hole 1171 corresponding to the position of the plug hole 1141. A plug hole seat 1172 is provided in the plug hole 1171. The plug hole seat 1172 is connected to the inner wall of one side of the plug hole 1171. The plug hole seat 1172 is provided with pin holes 1174 along the plugging direction. The two pin holes 1174 are used for the signal pins 51 of the bent male connector 10 to pass through and to be adapted and plugged into the signal plug hole 1151 of the bent female connector 11 inside the plug hole seat 1172. A mating gap 1173 is formed between the socket 1172 and the inner wall of the socket 1171 for inserting the plug shielding contact 4. The socket shielding contact 113 includes a base and a main spring claw portion 1131 and a side spring claw portion I 1132 disposed on the base. The extension length of the main spring claw portion 1131 is greater than the extension length of the side spring claw portion I 1132, so that the main spring claw portion 1131 extends into the mating gap 1173, while the side spring claw portion I 1132 is located in the mating gap. Inside the hole 1141, the main spring claw part 1131 is provided with several spring claws for elastic contact with the inner wall of the mating cavity 47 of the plug shielding contact 4. Specifically, the elastic contact of the main spring claw part 1131 is elastically in contact with the secondary shield 42. There are two or more side spring claw parts I 1132 arranged symmetrically. The side spring claw parts I 1132 are elastically in contact with the inner wall of the mating cavity 47, that is, the elastic contact of the side spring claw parts I 1132 is elastically in contact with the shielding plate 413.The socket shielding contact 113 has an overall C-shaped structure. The head of the plug shielding contact 4 extends into the insertion gap 1173, allowing the socket shielding contact 113 and the plug shielding contact 4 to make contact and conduct on three sides, thus improving the shielding effect. The socket shielding contacts 113 are all independently set and have a certain degree of self-adaptability, which can improve the reliability of the electrical contact between the socket shielding contact 113 and the plug shielding contact 4. It should be noted that, in order to cooperate with the shielding tail plate 45 of the right-angle male connector 10, a tail insertion cavity 118 is provided at a corresponding position on the adapter insulating housing 117. A shielding claw 119 is provided in the tail insertion cavity 118, and the shielding tail plate 45 extends into the shielding claw 119 in the tail insertion cavity 118 for contact.

[0037] In this design, the base of the socket shielded contact 113 has side spring claws II 1133 on both sides near the tail end. The side spring claws II 1133 are used to make electrical contact with the inner wall of the insertion hole 1141 of the common ground component 114, thus enabling all socket shielded contacts 113 to achieve common ground conduction. The tail end of the base has a connector 1134, which is adapted to connect with the connection hole at the head end of the shielding plate assembly 112, thereby achieving metal shielding conduction between the shielding plate assembly 112 and the socket shielded contact 113. The socket shielded contact 113 of this design adopts an integrated design with three spring claws on each side of the insertion area, which ensures the precision of component processing and reduces processing difficulty. At the same time, the connector assembly sequence determined by this structure facilitates fully automated assembly, improving production efficiency and yield.
