Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a high-speed connector and connector assembly. Background Technology

[0002] High-speed interconnect connectors are widely used in communication networks and data exchange systems, and high-speed backplane connectors are the core bridge for data communication. With the development of 5G and 6G product technologies, transmission rates are getting higher and higher, and the requirements for shielding of signals within the connector are becoming increasingly stringent.

[0003] Existing high-speed connectors for high-speed data transmission typically include a housing and multiple terminal modules mounted within the housing. The structure of the terminal modules can be found in [reference needed]. Figure 1 , Figure 2 The terminal module includes an insulator 101 and various terminals 102 fixed in the insulator 101. The terminals include signal terminals and ground terminals. The signal terminals are arranged in pairs to form differential pairs for transmitting differential signals. There are multiple differential pairs, arranged side-by-side. Ground terminals are provided on both sides of each differential pair. The terminals are wiring terminals. Both ends of the terminal 102 extend out of the insulator 101 in the extending direction. One end has a spring-loaded structure forming a mating end for contacting the pins of a mating connector, and the other end has a fisheye structure forming a crimping end for crimping and fixing to a printed circuit board. The mating ends of each terminal 102 constitute the mating ends of the terminal module, and the mating ends of each terminal module constitute the mating ends of the connector. A shielding plate 103 is provided on one side of the insulator 101 in the thickness direction. The shielding plate 103 has a portion extending to the mating end of the terminal 102 to provide shielding for the mating ends of the differential pairs.

[0004] As shielding requirements become increasingly stringent, the shielding structure of the aforementioned connectors can no longer meet the demands. The shielding effect of the portion of the shielding plate extending to the mating end of the differential pair on the mating area is limited. The mating end of the differential pair is subject to significant crosstalk from other directions, resulting in insufficient shielding and an inability to adapt to higher data transmission rates.

[0063] The basic concept of this high-speed connector is to use the partition plate set on the side shielding plate of the terminal module to form a shielding cavity with the shielding shell of the mating end of the terminal module. The shielding cavity shields the differential pair in different directions, which has a good shielding effect and is conducive to meeting the high-speed transmission performance of the connector.

[0064] The present invention will be described in detail below with reference to the embodiments.

[0065] Embodiment 1 of the connector assembly of this utility model:

[0066] like Figure 3 , Figure 4 As shown, the connector assembly includes a female connector 100 and a male connector 200. The female connector 100 includes multiple terminal modules 1, a shielding shell 2, an insulating shell 3, and a conductive snap plate 4. The female connector 100 constitutes a high-speed connector with terminal modules 1, and the male connector 200 constitutes a connector adapted to the female connector 100. Figure 1 The male connector 200 and the female connector 100 are not fully engaged. The mating ends of each terminal module 1 of the female connector 100 are installed in the shielding shell 2. The shielding shell 2 and each terminal module 1 are installed together in the insulating shell 3 of the female connector 100. The male connector 200 has a shell for adapting to the insulating shell 3 of the female connector 100 and male pins for adapting to and mating with each terminal of the terminal module 1 to form grounding conduction and signal conduction.

[0067] The mating direction of the female connector 100 and the male connector 200 is defined as the first direction, the parallel direction of each terminal module 1 is defined as the second direction, and the parallel direction of each terminal of the same terminal module 1 is defined as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other, with the first direction being the up-down direction, the second direction being the front-back direction, and the third direction being the left-right direction.

[0068] Combination Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 Terminal module 1 includes an insulator 12, terminals fixed in the insulator 12, and a first shielding plate 11 disposed on one side of the insulator 12. The terminals include signal terminals 13 and ground terminals 14. The signal terminals 13 are arranged in pairs to form differential pairs for transmitting differential signals. There are multiple differential pairs, each arranged side-by-side in the left-right direction. Ground terminals 14 are respectively provided on the left and right sides of each differential pair. Each terminal is a wiring terminal. One end of the terminal's extension direction has a spring structure forming a mating end for contacting the male pin of the male connector 200, and the other end has a fisheye structure forming a crimping end for crimping and fixing with the printed circuit board. The mating ends of each terminal constitute the mating ends of terminal module 1, and the mating ends of terminal module 1 constitute the mating ends of the connector. The female connector 100 is a right-angle connector, with its crimping end and mating end facing perpendicularly. In this embodiment, the mating end of terminal module 1 faces downwards. The mating ends of signal terminal 13 and ground terminal 14 extend out of insulator 12, and a mating end of ground terminal 14 is provided between the mating ends of two adjacent differential pairs. The first shielding plate 11 constitutes a side shielding plate. The first shielding plate 11 is fixed on one side of the thickness direction of insulator 12, which is the front-back direction. The first shielding plate 11 can provide shielding for the main body of the differential pair's traces on one side of the front-back direction.

[0069] To enhance the shielding effect of the mating area between the female connector 100 and the male connector 200, combined with Figure 12 , Figure 13 , Figure 14The mating ends of each terminal module 1 of the female connector 100 are installed in the conductive shielding shell 2. The shielding shell 2 can be made of metal or conductive plastic. The shielding shell 2 is provided with an insertion cavity 21 for the mating ends of the terminal modules 1 to be installed. That is, the mating ends of the signal terminal 13 and the grounding terminal 14 both extend into the insertion cavity 21. The signal terminal 13 does not contact the shielding shell 2. The first shielding plate 11 has a separator 111 at one end of the terminal module 1 at the mating end. A separator 111 is provided between the mating ends of any two adjacent differential pairs of the terminal module 1. The separator 111 separates two adjacent differential pairs of the same terminal module 1. The separator 111 is located at the mating end of the terminal module 1 and is installed into the mounting cavity 21 of the shielding shell 2 along with the mating end of the terminal module 1. The separator 111 is electrically connected to the inner walls of the opposite sides of the mounting cavity 21 and forms a shielding cavity 5 for shielding the corresponding differential pairs. The differential pairs are located in the corresponding shielding cavity 5. The separator 111 provided on the first shielding plate 11 of the terminal module 1, together with the shielding shell 2 on which the mating end of the terminal module 1 is installed, surrounds and shields the differential pairs. The shielding cavity 5 shields the differential pairs in different directions, resulting in good shielding effect, which is beneficial to meeting the high-speed transmission performance of the connector.

[0070] The inner wall of the insertion cavity 21 of the shielding shell 2 is provided with a mating groove 24. The mating groove 24 extends along the insertion direction of the female connector 100. The mating groove 24 corresponds one-to-one with the partition piece 111. The mating groove 24 is provided with a side opening for the edge of the corresponding partition piece 111 to be inserted along the extension direction of the mating groove 24. The edge of the partition piece 111 is inserted into the mating groove 24 from top to bottom, which helps to ensure the installation position of the terminal module 1. In other embodiments, the mating groove may not be provided, and the edge of the partition piece may be directly press-fitted with the inner wall surface of the insertion cavity.

[0071] The separator 111 is connected to the inner walls of the front and rear opposite sides of the insertion cavity 21. Each inner wall of the insertion cavity 21 has a mating groove 24 for interference fit between the front and rear edges of the separator 111. The interference fit between the mating groove 24 and the edge of the separator 111 facilitates reliable contact. In other embodiments, a spring claw can be provided on the separator, allowing for elastic contact between the spring claw and the inner wall of the mating groove.

[0072] The edge of the separator 111 is provided with an interference protrusion that interferes with the mating groove 24. The interference protrusion reduces the installation torque while forming the interference fit. In other embodiments, the interference protrusion may be omitted, and the thickness of the separator may be slightly larger than the width of the mating groove to form the interference fit.

[0073] Two interference protrusions are provided at intervals along the extension direction of the partition 111 on the same side edge in the width direction, namely the first interference protrusion 112 and the second interference protrusion 113. The groove depth direction of the mating groove 24 is the front-to-back direction, and the groove width direction is the left-to-right direction. The width direction of the partition 111 is the front-to-back direction, and the thickness direction is the left-to-right direction. The first interference protrusion 112 and the second interference protrusion 113 protrude towards the two sides of the partition 111 in the thickness direction, respectively. The interference protrusions form an interference fit with the corresponding groove wall of the mating groove 24 in the groove width direction, and the side of the partition 111 in the width direction is interference fitted with the bottom of the mating groove 24. The front and rear edges of the separator 111 are provided with a first interference-fit protrusion 112 and a second interference-fit protrusion 113. The first interference-fit protrusion 112 and the second interference-fit protrusion 113 are spaced apart along the overhang direction of the separator 111. The grooves of the mating grooves 24 on the opposite inner walls of the front and rear sides of the insertion cavity 21 are opposite each other, and the side openings of the mating grooves 24 face upwards. The interference-fit protrusions can be formed by stamping in the corresponding direction at the upper edge of the separator 111. Using interference-fit protrusions in different directions is beneficial for reliable fit. In other embodiments, only the first interference-fit protrusion or only the second interference-fit protrusion may be provided, and the protrusion direction of each interference-fit protrusion may be the same, as long as the separator and the mating groove form an interference fit.

[0074] The inner wall of the insertion cavity 21 of the shielding shell 2 is provided with a boss 22. The boss 22 is located on one side of the inner wall of the insertion cavity 21 in the front-back direction. The boss 22 is provided with a slot 23 with the opening facing the insulator 12 of the terminal module 1. The first shielding plate 11 of the terminal module 1 is also provided with a locking part 116 that is locked into the slot 23 at one end of the terminal module 1 at the insertion end. The opening of the slot 23 is upward and extends through left and right. The locking part 116 extends downward based on the main body of the first shielding plate 11. The slot 23 is adapted to the locking part 116, and the first shielding plate 11 can be limited by the slot 23. In other embodiments, the boss may not be provided, and the first shielding plate may not have a locking part.

[0075] The mounting portion 116 is provided with a first protrusion 114, which makes an interference fit with the inner wall of the slot 23. The first protrusion 114 constitutes a protrusion on the mounting portion that makes an interference fit with the side wall of the slot, which is beneficial to the reliable contact between the first shielding sheet 11 and the shielding shell 2. In other embodiments, the first protrusion may not be provided, and the side of the first shielding sheet may make surface contact with the side wall of the slot.

[0076] The main body of the first shielding sheet 11 is integrally connected to the separator 111. The separator 111 is bent perpendicularly to the main body of the first shielding sheet 11. The thickness direction of the separator 111 is perpendicular to the thickness direction of the main body, and the thickness direction of the separator 111 is left-right. The separator 111 is connected to the mounting part 116 and is bent based on the mounting part 116, which facilitates forming and saves space. In other embodiments, the separator can also be manufactured separately and forcibly fixed to the main body of the first shielding sheet.

[0077] The main body of the first shielding sheet 11 has a cantilever portion at one end of the terminal module 1 at the insertion end. This cantilever portion is a latching portion 116. Multiple latching portions 116 are spaced apart along the side-by-side direction of each differential pair of the terminal module 1, that is, multiple are spaced apart left and right. The outermost latching portion 116 in the side-by-side direction is connected to a separator 111 on one side edge. The two sides of the latching portions 116 located between the two outermost latching portions 116 are respectively connected to separators 111. That is, the leftmost latching portion 116 is connected to a separator 111, the rightmost latching portion 116 is connected to a separator 111, and the left and right sides of each latching portion located between the leftmost and rightmost latching portions are respectively connected to a separator 111, which facilitates forming. In other embodiments, if space permits, each partition can be connected to a corresponding overhang; the overhang may not be a snap-fit ​​part that is snapped into the corresponding slot, the inner wall of the insertion cavity of the shield shell is not provided with a boss, and the overhang of the partition simply extends into the insertion cavity.

[0078] The grounding terminal 14 of terminal module 1 is arranged side by side with the differential pairs. A separator 111 is provided between the grounding terminal 14 and each adjacent differential pair. A separator 111 is provided between any differential pair and the grounding terminal 14 connected to it, which helps to ensure the shielding effect. In other embodiments, for grounding terminals with differential pairs on both the left and right sides, a separator can also be provided between the differential pairs on both sides.

[0079] The grounding terminal 14 is provided with a grounding terminal protrusion 141 that abuts against the adjacent partition plate 111. The grounding terminal protrusion 141 abuts against the side of the partition plate 111 in the thickness direction, which can improve the shielding effect. In other embodiments, the grounding terminal protrusion may not be provided, and the grounding terminal does not contact the partition plate.

[0080] The position of the mounting portion 116 of the first shielding plate 11 corresponds to the position of the grounding terminal 14, and the two adjacent partition plates 111 located on both sides of the grounding terminal 14 are connected to the same mounting portion 116. The two partition plates 111 and the inner walls of the opposite sides of the insertion cavity 21 form a space to accommodate the boss 22 and the grounding terminal 14.

[0081] All terminal modules 1 have their mating ends installed within the same shielding shell 2. The shielding shell 2 has a corresponding insertion cavity 21 for each terminal module 1, with one insertion cavity 21 for each terminal module 1. The insertion cavities 21 are spaced apart along the front-to-back direction. The first shielding plates 11 of each terminal module 1 form a common ground through the shielding shell 2, which helps to improve the shielding effect. In other embodiments, each terminal module can also be equipped with a shielding shell, which is smaller in size, and the shielding shells are installed side by side in an insulating shell.

[0082] The mating ends of all terminals of the same terminal module 1 are inserted into the same insertion cavity 21. The insertion cavity 21 has only one sidewall in the left and right directions, and the other side is an open structure. One end of the left and right ends of the inner walls on the front and rear sides of the insertion cavity 21 is connected through the sidewall, while the other end is not connected, which ensures the formability of the shielding shell 2 while saving space. The partition plate 111 at the outermost edge of the first shielding plate 11 corresponds to the side opening of the insertion cavity 21 and can block the side opening to cooperate with the inner walls on the front and rear sides of the insertion cavity 21 to form a shielding cavity 5 for shielding the corresponding differential pairs.

[0083] Terminal module 1 also includes a second shielding plate 15 on the same side as the first shielding plate 11, combined with Figure 10 The second shielding plate 15 has a bent claw 151 with a hole formed at the claw 151. The first shielding plate 11 has a through hole 115 for the claw 151 to pass through. The claw 151 passes through the first shielding plate 11 and into the insulator 12 to contact the grounding terminal 14. The grounding terminal 14 has a contact hole for the claw 151 to be forcibly installed. The first shielding plate 11 and the second shielding plate 15 cooperate to form a double-layer shield. The main body of the first shielding plate 11 can reduce the impact of the hole left by the claw 151 on the shielding effect. In other embodiments, the second shielding plate may be omitted.

[0084] Both the first shielding plate 11 and the second shielding plate 15 have a portion that contacts the shielding shell 2. The separator 111 and the mounting portion 116 of the first shielding plate 11 constitute the portion that contacts the shielding shell 2. The main body of the second shielding plate 15 is located outside the main body of the first shielding plate 11, that is, on the side facing away from the insulator 12. The end of the main body of the second shielding plate 15 located at the insertion end of the terminal module 1 has a second protrusion 152, which constitutes the protrusion on the second shielding plate 15 that contacts the shielding shell 2. The inner wall of the upper cavity opening of the insertion cavity 21 has an interference fit surface 25, and the wall thickness at the interference fit surface 25 is relatively thin. When the insertion end of the terminal module 1 is inserted, the end of the second shielding plate 15 with the second protrusion 152 is inserted into the insertion cavity 21, and the second protrusion 152 forms an interference fit with the interference fit surface 25, forming a shielded conduction, and the shielding is reliable. In other embodiments, the second protrusion may not be provided, and the second shielding plate may not contact the shielding shell.

[0085] Terminal module 1 also includes a third shielding plate 16 disposed on the other side of insulator 12, combined with Figure 11 The third shielding plate 16 has a locking hole 161. The locking claw 151 on the second shielding plate 15 passes through the insulator 12 and the grounding terminal 14 in the insulator 12 from one side and passes through to the other side, locking into the locking hole 161 of the third shielding plate 16 on the other side. The locking claw 151 is in contact with both the grounding terminal 14 and the third shielding plate 16, forming a shielded conduction. The end of the third shielding plate 16 located at the insertion end of the terminal module 1 has a groove, which is a mating groove 162. The edge of the separator 111 of the first shielding plate 11 facing the third shielding plate 16 is locked into the corresponding mating groove 162, forming a shielded conduction, which helps to enhance the shielding effect. In other embodiments, the mating groove may not be provided, and the separator of the first shielding plate does not contact the third shielding plate. The application of the double-sided shielding structure of the terminal module 1 can greatly reduce crosstalk, improve the SI performance of the high-speed backplane connector, and meet the needs of higher speed transmission.

[0086] The groove wall of the fitting groove 162 is provided with a protrusion that interferes with the separator 111, which facilitates reliable contact. In other embodiments, the groove wall of the fitting groove may not have a protrusion, and the groove width of the fitting groove may be slightly smaller than the thickness of the separator to form an interference fit.

[0087] The insulator 12 has heat-riveting posts on both sides in the thickness direction. The first shielding plate 11, the second shielding plate 15, and the third shielding plate 16 have through holes for the corresponding heat-riveting posts to pass through, so as to fix the shielding plate and the insulator 12 together by heat riveting process, which increases the stability of the shielding plate and the insulator 12 and further improves the signal transmission performance of the connector.

[0088] To enhance the shielding effect of the crimped end of the terminal module 1, the grounding terminal 14 and shielding plate of each terminal module 1 are grounded together through the conductive buckle plate 4. The grounding terminal 14 and shielding plate are both installed on the conductive buckle plate 4. The fisheye portion of the grounding terminal 14 protrudes through the conductive buckle plate 4. The conductive buckle plate 4 is provided with a clearance hole for avoiding the fisheye portion of the signal terminal 13. The conductive buckle plate 4 can protect the fisheye end and further improve the SI performance of the product.

[0089] Embodiment 2 of the connector assembly of this utility model:

[0090] The connector assembly in this embodiment differs from the connector assembly in Embodiment 1 above in that the terminal module separator of the female connector 100 and the insertion cavity of the shielding shell are combined with Figure 15 , Figure 16 , Figure 17In this embodiment, the first shielding plate 11 has no separator on one side, that is, there is no separator on the outer side of the outermost differential pair of the terminal module. The insertion cavity of the shielding shell 2 has two side walls along the arrangement direction of each differential pair. The left and right ends of the opposite inner walls of the front and rear sides of the insertion cavity are connected by the corresponding side walls. Figure 16 The signal terminal 13 of the outermost differential pair of the terminal module does not have a grounding terminal plug-in end or a separator. Instead, it is shielded by the corresponding side wall of the loading cavity of the adjacent shielding shell 2 and the adjacent inner separator 111 on the other side, which together with the front and rear opposite inner walls of the loading cavity to form a shielding cavity for the differential pair.
