Description

Technical Field

[0001] This invention relates to a connector assembly, and more particularly to a connector assembly comprising a plug connector and a socket connector. Background Technology

[0002] Chinese invention patent publication number CN105529547B discloses a shielding assembly including a wall having a tubular container. The tubular container extends along the entire connection area and is adapted to accommodate signal lines. The wall and shielding assembly provide shielding in the connection area and simultaneously have a shape that allows for simple manufacturing and installation of the wall and shielding assembly. The wall has a U-shaped cross-section; in other embodiments, the wall may also have a V-shaped or C-shaped cross-section. The wall with the U-shaped cross-section has a common base and engages two legs (or sides) located on the longitudinal side of the cable assembly. The common base and legs thus extend along the cable direction. The wall may further have an open longitudinal side. Through this open longitudinal side, the signal line can be connected to a PCB. The PCB may include conductive layers, particularly ground layers, such that the wall, together with the PCB, shields the connection area 360° around the cable direction.

[0003] Chinese invention patent publication number CN106463858B discloses a cable connector comprising a shielding structure mounted on a substrate and electrically connected to a grounding pad. The shielding structure includes a cap and a plurality of sidewalls extending from the cap toward the substrate. Each of the transmitting and receiving cables is positioned between a different pair of sidewalls.

[0004] Chinese Utility Model Patent Publication No. CN114389113A discloses a first shielding member in the form of a pair of first shielding plates. Each of the first shielding plates extends longitudinally at least along the entire length of the corresponding terminal block and laterally at least along the tail of a plurality of grounding terminals and a crossbar of the corresponding terminal block. When the cable is connected to a plurality of conductive terminals of a cable connector, the pair of first shielding plates are mounted (e.g., by laser welding) from the outside of the two terminal blocks onto and in contact with the plurality of grounding terminals of the corresponding terminal blocks, and press against and in contact with the shielding conductor, thereby holding the shielding conductor on the crossbar and making contact between the shielding conductor and the crossbar. In this way, the first shielding member, grounding terminals, crossbar, and shielding conductor together form a shield around the connection point between the signal conductor and the signal terminal, thereby improving the signal integrity of signal transmission between the cable and the cable connector.

[0005] Chinese invention patent publication CN116073193A discloses a ground bus coupled to a circuit card. The ground bus can be electrically connected to the circuit card, for example, to the ground plane of the circuit card. The ground bus provides electrical shielding for the signal conductors of a cable. The ground bus is electrically connected to the cable's shielding structure, such as the cable's ground shield and / or the cable's shielded wires. In an exemplary embodiment, the ground bus is soldered to the ground shield. The ground bus extends along an exposed portion and provides shielding for the exposed portion. The ground bus is shaped and positioned relative to the exposed portion to control impedance along the signal path.

[0006] Chinese invention patent publication number CN116191136A discloses a method that, by setting a first grounding plate and a second grounding plate and placing the first grounding plate and the second grounding plate between the first mating plate portion and the second mating plate portion along the thickness direction of the tongue plate, the mutual interference between the first mating plate portion of the first conductive terminal and the second mating plate portion of the second conductive terminal during signal transmission is reduced, thereby improving the quality of signal transmission.

[0007] Chinese invention patent publication CN117096679A discloses a plurality of grounding terminals spaced apart on the surface of a plastic substrate for electrical contact with grounding terminals inside a female connector. A first signal terminal group (i.e., two first signal terminals) is provided between every two grounding terminals to provide electromagnetic shielding for the first signal terminals in the first signal terminal group. An electrical connection structure is embedded in the first insulator of the plastic substrate. The electrical connection structure is fixed and electrically connected to the plurality of grounding terminals to connect them in series to form a common ground mesh structure, achieving a common ground effect similar to PCB vias. This improves the electromagnetic shielding effect between the various first signal terminal groups, thereby improving the crosstalk performance of the cable module and enhancing the signal transmission quality of the cable module.

[0008] However, for connectors with different structures, various electromagnetic shielding designs still need to be developed to prevent electromagnetic interference from affecting signal transmission, so that the connector can have high signal integrity at high transmission speeds.

[0159] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0160] See Figures 1 to 4 , Figure 6 A first embodiment of the connector assembly 100 of the present invention includes a plug connector 1 and a socket connector 2.

[0161] The plug connector 1 includes a plug housing 11, a substrate 12, a plurality of cables 13, a cover 14, and at least one grounding shield 15 mounted on the surface of the substrate 12. In this embodiment, the substrate 12 is a circuit board, but in other variations, the substrate 12 may also be an equivalent circuit board structure, such as a circuit board-like structure composed of metal and plastic. The substrate 12 has a connecting plate portion 121 and a mating plate portion 122 located at the rear and front respectively along a front-rear direction D1 (arrow pointing forward). The connecting plate portion 121 and the mating plate portion 122 are electrically connected, and the substrate 12 has an upper surface facing upward and a lower surface facing downward along a vertical direction D2 (arrow pointing upward). The upper and lower surfaces of the connecting plate portion 121 are each provided with multiple pairs of signal conductive pads 121a arranged side-by-side along a left-right direction D3 (arrow pointing to the right), and multiple ground conductive pads 121b respectively provided on both sides of each pair of signal conductive pads 121a. These cables 13 are electrically connected to the multiple pairs of signal conductive pads 121a and the multiple ground conductive pads 121b on the connecting plate portion 121, and the connection between the connecting plate portion 121 and the multiple cables 13 is covered by the cover body 14. The substrate 12, the multiple cables 13 and the cover body 14 are assembled together on the plug housing 11. The upper and lower surfaces of the mating plate portion 122 are provided with multiple pairs of signal conductive pads 122b arranged side-by-side along the left-right direction D3, and multiple ground conductive pads 122c respectively provided on both sides of each pair of signal conductive pads 122b, that is, each pair of signal conductive pads 122b has ground conductive pads 122c on both the left and right sides. In this embodiment, the connecting plate portion 121 of the substrate 12 is a connecting cable 13, but in other embodiments, the connecting plate portion 121 of the substrate 12 may also be connected to a circuit board.

[0162] In this first embodiment, two grounding shield covers 15 are provided, which are formed by bending metal sheets. The two grounding shield covers 15 are respectively mounted on the upper and lower surfaces of the substrate 12 and contact the corresponding plurality of grounding conductive pads 122c. Specifically, each grounding shield cover 15 has a plurality of contact portions 151 that respectively contact the plurality of grounding conductive pads 122c, a plurality of wall portions 152 located between the plurality of contact portions 151 and spaced apart from the plurality of pairs of signal conductive pads 122b, and a plurality of connecting portions 153 respectively connecting the plurality of contact portions 151 and the plurality of wall portions 152. In this first embodiment, the contact portions 151 and the wall portions 152 extend approximately along the left-right direction D3 and are staggered in the up-down direction D2. The connecting portion 153 extends approximately along the vertical direction D2, connecting the contact portion 151 and the wall portion 152. The cross-section of the connected wall portion 152 and the connecting portion 153 in the vertical direction D2 is approximately inverted U-shaped, and both the wall portion 152 and the connecting portion 153 have a shielding effect. The cross-section of the connected contact portion 151 and the connecting portion 153 in the vertical direction D2 is approximately U-shaped, thus making the grounding shield cover 15 generally wavy. The contact portion 151, the wall portion 152, and the connecting portion 153 have the same length along the front-back direction D1. Each wall portion 152 and the corresponding pair of signal conductive pads 122b are spaced apart in the vertical direction D2, thus making the grounding shield cover 15 and the substrate 12 together surround the multiple pairs of signal conductive pads 122b. In this first embodiment, the multiple contact portions 151 of the grounding shield cover 15 are respectively fixed to the multiple grounding conductive pads 122c of the substrate 12 by welding, but this is not a limitation. Preferably, a grounding layer (not shown) parallel to the upper and lower surfaces of the substrate 12 is provided within the substrate 12. Preferably, the grounding layer is electrically connected to the plurality of grounding conductive pads 122c.

The insulating base 232 partially covers the terminal group 231, i.e., the fixed sections 235a, 236a of the signal terminals 235 and ground terminals 236, to hold the terminal group 231 in place. Each signal terminal 235 has a contact segment 235d with a free end 235e and a contact portion 235f for contacting the signal conductive pad 122b. In this first embodiment, the contact segment 236d of each ground terminal 236 is bent and protrudes in the left-right direction D3.

[0164] Each terminal module 23 in this first embodiment is provided with a first grounding shield 24. The first grounding shield 24 is disposed in the terminal group 231 along the left-right direction D3 and is electrically connected to one side of the plurality of grounding terminals 236 in the up-down direction D2, and is located on the side where the fixed section 236a and the welding section 236b are bent towards each other. In this first embodiment, the first grounding shield 24 is formed by bending a metal plate. The first grounding shield 24 includes a first shielding area 24a and a second shielding area 24b that are connected in a generally L-shape. The first shielding area 24a and the second shielding area 24b are generally wavy. The first shielding area 24a is used to shield the fixing section 235a of the signal terminal 235, and the second shielding area 24b is used to shield the soldering section 235b of the signal terminal 235. Each first shielding area 24a and the second shielding area 24b has a plurality of contact portions 24c that are electrically connected to the grounding terminal 236, a plurality of wall portions 24d located between the plurality of contact portions 24c and corresponding to the plurality of pairs of signal terminals 235, and a plurality of connecting portions 24e connecting adjacent contact portions 24c and adjacent wall portions 24d. The contact portion 24c of the first shielding area 24a is electrically connected to the fixed section 236a of the grounding terminal 236. The wall portion 24d of the first shielding area 24a is connected between the plurality of contact portions 24c through the connecting portion 24e, spanning the fixed section 235a of the plurality of signal terminals 235 and spaced apart from the fixed section 235a of the plurality of signal terminals 235. Each wall portion 24d is connected to two connecting portions 24e to form an inverted U-shaped shielding structure, and both the wall portion 24d and the connecting portion 24e have a shielding effect. The contact portion 24c of the second shielding area 24b is welded and fixed to the welding section 236b of the grounding terminal 236. The wall portion 24d of the second shielding area 24b is connected between the plurality of contact portions 24c through the connecting portion 24e, spanning the welding section 235b of the plurality of signal terminals 235 and spaced apart from the welding section 235b of the plurality of signal terminals 235.

[0165] In addition, in this first embodiment, the first grounding shield 24 further includes a plurality of folded connecting portions 24g, a plurality of sleeve portions 24h, and a plurality of connecting segments 24i. The folded connecting portions 24g extend from each wall portion 24d of the second shielding area 24b toward the fixing segment 235a of the signal terminal 235, and are spaced at intervals corresponding to the soldering segments 235b of the signal terminal 235, and connect to one wall portion 24d of the first shielding area 24a. The sleeve portions 24h are respectively sleeved onto the plurality of grounding terminals 24g. The fixed section 236a of the 36, and the contact portion 24c of the aforementioned first shielding area 24a is electrically connected to the fixed section 236a of the grounding terminal 236 by welding to the sleeve portion 24h. In this first embodiment, each sleeve portion 24h of the first grounding shield 24 extends a protrusion 24j and 24k from the front and back respectively, the function of which will be explained later. The connecting section 24i connects the sleeve portion 24h and the contact portion 24c of the second shielding area 24b, and is approximately abutted against the welding section 236b of the grounding terminal 236.

[0166] Each terminal module 23 in this first embodiment is provided with two second grounding shields 25. The two second grounding shields 25 are generally elongated and wavy, spaced apart along the front-rear direction D and respectively located on the front and rear sides of the insulating base 232. Each second grounding shield 25 has multiple contact portions 25c, multiple wall portions 25d located between the multiple contact portions 25c and respectively corresponding to the multiple pairs of signal terminals 235, and multiple connecting portions 25e connecting adjacent contact portions 25c and adjacent wall portions 25d. Both the wall portions 25d and the connecting portions 25e have a shielding effect. The multiple second grounding shields 25 are electrically connected to the multiple grounding terminals 236 by contacting the protrusions 24j and 24k of the sleeve portion 24h of the first grounding shield 24 through the contact portions 25c. They are located on the other side of the multiple grounding terminals 236 in the vertical direction D2 relative to the first grounding shield 24. Therefore, in each terminal module 23, a better shielding effect can be achieved by using two second grounding shields 25 and a first grounding shield 24, in conjunction with the grounding terminal 236 surrounding the fixed section 235a and the soldering section 235b of the signal terminal 235. It should be noted that in other embodiments, the second grounding shield 25 may be provided as one or more. Furthermore, in this first embodiment, the first grounding shield 24 may be disposed on the insulating base 232 and pressed onto the plurality of grounding terminals 236 by insert molding, thereby electrically connecting the plurality of grounding terminals 236. The second grounding shield 25 is disposed on the first grounding shield 24 by soldering, thereby electrically connecting the plurality of grounding terminals 236 through the first grounding shield 24.

[0167] See Figure 2 , Figure 6 When the plug connector 1 mates with the socket connector 2, the contact portion 235f of each pair of signal terminals 235 of the socket connector 2 is electrically connected to the corresponding pair of signal conductive pads 122b, and the plurality of walls 152 of the grounding shield cover 15 covers and shields the free ends 235e of the plurality of signal terminals 235. Preferably, the grounding shield cover 15 covers and shields the free ends 235e of the plurality of signal terminals 235 to their contact portions 235f, and the contact segment 236d of the grounding terminal 236 of the socket connector 2 abuts against the outside of the connecting portion 153 of the corresponding grounding shield cover 15 along the left-right direction D3. That is, the contact segment 236d of each grounding terminal 236 extends into the connecting portion 153 of two adjacent inverted U-shaped shielding structures and abuts against the outside of the connecting portion 153 of the grounding shield cover 15, thus giving full play to the shielding function of the grounding shield cover 15 when the plug connector 1 and the socket connector 2 mate.

[0168] Therefore, as described above, the advantage of this invention is that, in the plug connector 1, the grounding shield 15 and the substrate 12 together surround at least a portion of the plurality of pairs of signal conductive pads 122b, thus providing a better shielding effect. Similarly, in the socket connector 2, the first grounding shield 24, the second grounding shield 25, and the plurality of grounding terminals 236 together surround the plurality of pairs of signal terminals 235, thus providing a better shielding effect. When the plug connector 1 and the socket connector 2 are mated, the grounding terminals 236 of the socket connector 2 are electrically connected to the grounding shield 15, and each pair of signal terminals 235 of the socket connector 2 is electrically connected to the corresponding pair of signal conductive pads 122b. The grounding shield 15 covers and shields the free ends 235e of the plurality of pairs of signal terminals 235 or the free ends 235e of the plurality of pairs of signal terminals 235 to their contact portions 235f, forming a complete shielding effect between the plug connector 1 and the socket connector 2, which can provide better signal integrity at high transmission speeds.

[0169] See Figure 7 and Figure 9A second embodiment of the connector assembly of the present invention differs from the first embodiment in that the two grounding shields 15' of the plug connector 1 in this second embodiment are embedded and ejected into the plug housing 11, and the plurality of contact portions 151 of the grounding shields 15' are respectively pressed against the plurality of grounding conductive pads 122c. Each grounding shield 15' also has a plurality of fixing portions 154 formed by bending from the rear end of the plurality of wall portions 152 away from the contact portions 151, and the cross section of the vertical direction D2 of each fixing portion 154 is inverted U-shaped. In other words, the fixing portion 154 is formed by bending twice relative to the wall portion 152, and the plug housing 11 covers the entire grounding shield 15' near the rear end portion and the fixing portion 154. Through the design of the fixing portion 154, the bonding strength between the plug housing 11 and the grounding shield 15' can be strengthened. Furthermore, the contact portion 151 has a protrusion 151a protruding away from the wall portion 152, that is, towards the substrate 12, for pressing against the corresponding grounding conductive pad 122c, thus further ensuring that the contact portion 151 can reliably press against the grounding conductive pad 122c. In this second embodiment, the substrate 12, the plurality of cables 13, and the cover 14 are modularly assembled together into the plug housing 11, and the plurality of grounding conductive pads 122c of the substrate 12 are pressurized to contact the protrusion 151a of the contact portion 151 of the two grounding shield covers 15'.

[0170] See Figure 10 and Figure 14 The third embodiment of the connector assembly 100a of the present invention differs from the first embodiment in that, in the first embodiment, a grounding shield 15 is respectively provided on the upper and lower surfaces of the substrate 12, while in the third embodiment, multiple grounding shields 15” are provided, that is, multiple grounding shields 15” are respectively provided on the upper and lower surfaces of the substrate 12. Each grounding shield 15” includes several contact portions 151, wall portions 152 and connecting portions 153. Alternatively, it can be regarded as changing each grounding shield 15” in the first embodiment to a multi-segment discontinuous structure. This design is to accommodate the fact that the multiple pairs of signal terminals 235 of the socket connector 2 may include high-speed signal terminals and non-high-speed signal terminals. Among them, the shielding requirements of high-speed signal terminals are higher than those of non-high-speed signal terminals. Therefore, the positions of the multiple grounding shields 15” are mainly matched with the positions of high-speed signal terminals. In addition, in this third embodiment, multiple connecting segments 155 are respectively connected between the contact portions 151 of the upper and lower grounding shields 15”, so that the corresponding upper and lower grounding shields 15” are connected as one unit. In this way, the shielding effect can be improved.

[0171] And such as Figure 11As shown, in this third embodiment, each wall portion 152 of the grounding shield cover 15” is longer than the contact portion 151 and the connecting portion 153 in the front-to-back direction D1.

[0172] See Figures 12 to 14 Furthermore, compared to the first grounding shield 24 of the first embodiment, the first grounding shield 24' of the socket connector 2 in this third embodiment, as... Figure 13 As shown, [the following text is omitted] Figure 4 In the first embodiment, the reverse connecting portion 24g and the sleeve portion 24h are connected, and the connecting segment 24i' is connected between the wall portion 24d of the first shielding area 24a and the wall portion 24d of the second shielding area 24b. The contact portion 24c of the first shielding area 24a is welded and fixed to the fixing segment 236a of the grounding terminal 236 in a sheet shape, and the contact portion 24c of the second shielding area 24b is welded and fixed to the welding segment 236b of the grounding terminal 236.

[0173] Furthermore, the first grounding shield 24' is directly disposed on one side of the plurality of grounding terminals 236 in the vertical direction D2 by welding, and is electrically connected to the plurality of grounding terminals 236. Moreover, the two second grounding shields 25, similar to those in the first embodiment, are disposed on the other side of the plurality of grounding terminals 236 in the vertical direction D2 by welding, and are electrically connected to the plurality of grounding terminals 236, thus forming an effect of surrounding the signal terminal 235 together with the first grounding shield 24'.

[0174] Furthermore, in this third embodiment, as Figure 13 , Figure 14 As shown, the contact segment 236d' of each grounding terminal 236 of the socket connector 2 is bent and protrudes in the vertical direction D2. When the plug connector 1 mates with the socket connector 2, the contact segment 236d' of the grounding terminal 236 of the socket connector 2 abuts against the contact portion 151 of the corresponding grounding shield 15 in the vertical direction D2 to electrically connect the grounding shield 15. Therefore, the contact segment 236d' of the grounding terminal 236 and the grounding shield 15 can have a more stable contact.

[0175] To further clarify, such as Figure 14A As shown, the plurality of grounding shields 15” disposed on each surface of the substrate 12 can also be connected as a single unit. Figure 2 The grounding shield cover 15 has a continuous structure.

[0176] See Figure 15 and Figure 18A fourth embodiment of the connector assembly 100b of the present invention differs from the first embodiment in that, in terms of the plug connector 1, compared to the first embodiment where the grounding shield cover 15 has a wavy structure, the grounding shield cover 15”' of the fourth embodiment is formed by metal die casting and is in the form of a grid. The grounding shield cover 15”' has a plurality of contact portions 151' that respectively contact the plurality of grounding conductive pads 122c, a plurality of wall portions 152' located between the plurality of contact portions 151' and respectively spaced between the plurality of signal conductive pads 122b, and a plurality of connecting portions 153' that are respectively connected to the plurality of contact portions 151' and the plurality of wall portions 152'. In this fourth embodiment, the plurality of wall portions 152' are connected to form a whole flat plate, the plurality of connecting portions 153' are spaced apart along the left-right direction D3, and the plurality of contact portions 151' are the areas where the bottom of the plurality of connecting portions 153' contacts the plurality of grounding conductive pads 122c. Therefore, the plurality of connecting portions 153' are respectively connected between the flat plate-shaped wall portions 152' and the plurality of contact portions 151'.

[0177] In addition, compared to the first embodiment, each tab 24j of the first grounding shield 24 of the socket connector 2 is replaced by a pair of clamping tabs 24j', or it can be regarded as the contact segment of the grounding terminal being replaced by the pair of clamping tabs 24j'. Each clamping tab 24j' extends along the front-rear direction D1 and has an abutment portion 24n for contacting the corresponding grounding shield cover 15”' of the plug connector 1. The abutment portions 24n of each pair of clamping tabs 24j' are bent towards each other to define a clamping portion 24m. When the plug connector 1 mates with the socket connector 2, the abutting portions 24n of the plurality of clamping pieces 24j' of the socket connector 2 abut against the corresponding connecting portion 153' of the grounding shield 15”' along the left-right direction D3. Specifically, in this fourth embodiment, each connecting portion 153' of the grounding shield 15”' has two abutting portions 24n of clamping pieces 24j' abutting from the left and right respectively. That is to say, the two abutting portions 24n together clamp the connecting portion 153'.

[0178] See Figure 19 and Figure 23A fifth embodiment of the connector assembly 100c of the present invention differs from the first embodiment in that, in this fifth embodiment, the two grounding shield covers 15”” of the plug connector 1 are formed by metal die casting, and their structure is roughly similar to that of the fourth embodiment, being grid-shaped. The grounding shield cover 15”” has multiple contact portions 151”” that respectively contact the multiple grounding conductive pads 122c, multiple wall portions 152”” located between the multiple contact portions 151”” and respectively spaced between the multiple pairs of signal conductive pads 122b, and multiple… The multiple connecting portions 153” connected to the multiple contact portions 151” and the multiple wall portions 152” are also the areas where the bottom of the multiple connecting portions 153” contacts the multiple grounding conductive pads 122c. The difference is that each connecting portion 153” is plate-shaped and has a receiving groove 153b formed on one side of its surface in the left-right direction D3. The leading edge of the multiple connecting portions 153” facing the insertion direction (i.e., opposite to the arrow direction in the front-back direction D1) is a sloped surface that extends forward and downward. Therefore, as Figure 22 As shown, the grounding shield 15”” and the substrate 12 together surround at least a portion of the plurality of pairs of signal conductive pads 122b.

[0179] Furthermore, the insulating body 22 of the socket connector 2 has multiple surrounding walls 221 corresponding to the contact sections 235d of the multiple pairs of signal terminals 235. These surrounding walls 221 are U-shaped and surround the left and right sides and ends of the contact sections 235d of the multiple pairs of signal terminals 235, protecting the contact sections 235d of the multiple pairs of signal terminals 235 and the shielding space formed by the multiple connecting portions 153” of the grounding shield cover 15”, the wall portion 152”, and the substrate 12. Additionally, in this fifth embodiment, the first grounding shield 24” can be generally sheet-like and embedded into the insulating body 22 and pressed against the multiple grounding terminals 236. Furthermore, in this fifth embodiment, as... Figure 23 As shown, the fixing section 236a' of the grounding terminal 236 has a U-shaped structure. The first grounding shield 24” is generally plate-shaped and is formed by stamping, including multiple wall portions 24d' and multiple crimping portions 24p, as shown. Figure 21 , Figure 22 As shown, the plurality of wall portions 24d' are the unpressed parts of the plate, each spaced apart from the spring arm sections 235c corresponding to the signal terminals 235. The plurality of crimping portions 24p extend in a spring arm structure along the front-rear direction D1 to contact the grounding terminals 236. The two second grounding shields 25 are elongated strips electrically connected to the fixed sections 236a' of the plurality of grounding terminals 236 by welding.

[0180] When the plug connector 1 mates with the socket connector 2, the plurality of grounding terminals 236 of the socket connector 2 abut against the corresponding connecting portion 153” of the grounding shield cover 15”” along the left-right direction D3, and are accommodated in the receiving groove 153b of the connecting portion 153”” of the grounding shield cover 15””. Therefore, the receiving groove 153b of the connecting portion 153”” has the function of guiding and restricting the grounding terminals 236. The plurality of grounding shield covers 15”” and shields the free ends 235e of the plurality of signal terminals 235 or the free ends 235e of the plurality of signal terminals 235 to their contact portions 235f.

[0181] See Figures 24 to 27 A sixth embodiment of the connector assembly 100d of the present invention differs from the fifth embodiment in that, in this sixth embodiment, the grounding shield cover 15””’ connecting portion 153”’ of the plug connector 1 does not have the receiving groove 153b of the fifth embodiment, and has a contact slope 153a inclined toward the up-down direction D2 in the insertion direction facing the socket connector 2 (i.e., the arrow direction opposite to the front-back direction D1).

[0182] In addition, in the socket connector 2, the length of the grounding terminal 236 in the front-to-back direction D1 is shorter than that of the signal terminal 235, and the first grounding shield 24”' is plate-shaped and disposed in the insulating body 22. The first grounding shield 24”' is spaced apart from the multiple pairs of signal terminals 235, and its position corresponds approximately to the spring arm section 235c and contact section 235d of the multiple pairs of signal terminals 235 and has no direct contact with the multiple pairs of signal terminals 235. However, similarly, the first grounding shield 24”', the second grounding shield 25 and the multiple grounding terminals 236 together surround the multiple pairs of signal terminals 235.

[0183] When the plug connector 1 mates with the socket connector 2, the plurality of grounding terminals 236 of the socket connector 2 abut against the contact slope 153a of the corresponding grounding shield 15””’ connecting portion 153””’ along the vertical direction D2, so as to electrically connect the grounding shield 15””’. Therefore, when the plug connector 1 mates with the socket connector 2, a complete shielding effect is formed between the plug connector 1 and the socket connector 2.

[0184] See Figures 28 to 30This is a seventh embodiment of the connector assembly of the present invention. The difference from the sixth embodiment is that in this seventh embodiment, each grounding terminal 236' of each terminal module 23" of the socket connector 2 has a metal portion 236e made of metal and a conductive plastic portion 236f formed by covering the metal portion 236e with conductive plastic. The metal portion 236e is configured to correspond to the spring arm segment 236c and contact segment 236d as described in the first embodiment above. The conductive plastic portion 236f covers the metal portion 236e and is configured to correspond to the fixing segment 236a and soldering segment 236b as described in the first embodiment above. Furthermore, the first grounding shield 24"" of the socket connector 2 is embedded and ejected onto the conductive plastic portion 236f of the grounding terminal 236' and contacts the metal portion 236e of the grounding terminal 236'. The first grounding shield 24"" has multiple contact portions 24c' located between the multiple contact portions 24c'. Furthermore, in this seventh embodiment, multiple wall portions 24d' corresponding to the fixed section 235a of the multiple pairs of signal terminals 235, and multiple connecting portions 24e' connecting adjacent contact portions 24c' and adjacent wall portions 24d' are provided. In this seventh embodiment, the multiple contact portions 24c' are arranged in pairs along the front-back direction D1, and each pair of contact portions 24c' contacts the metal portion 236e of the grounding terminal 236' at the position corresponding to the fixed section in opposite directions. The contact portions 24c' are covered by conductive plastic portions 236f, and each pair of contact portions 24c' is connected to the wall portion 24d' through the connecting portion 24e', so that the multiple wall portions 24d' are arranged along the left-right direction D3, and the multiple pairs of contact portions 24c' are also arranged along the left-right direction D3. In addition, this seventh embodiment also provides another first grounding shield 24”' in the form of a plate as in the sixth embodiment. Therefore, the first grounding shield 24”” surrounds the signal terminal to achieve a better shielding effect. This seventh embodiment also includes a second grounding shield 25.

[0185] See Figures 31 to 33In an eighth embodiment of the connector assembly of the present invention, the first grounding shield 24”” and the other first grounding shield 24”’ are the same as in the seventh embodiment. The difference from the seventh embodiment is that in this eighth embodiment, the grounding terminal 236 of each terminal module 23”’ of the socket connector 2 is entirely made of metal. The second grounding shield 25 has a second grounding shield body 25a and a plurality of housing portions 25b. The housing portions 25b are sleeved on the fixing section 236a and the soldering section 236b of the grounding terminal 236 and one end is in contact with the second grounding shield body 25a, thus achieving a shielding effect. The first grounding shield 24””, the second grounding shield body 25a and the plurality of housing portions 25b are disposed on the corresponding insulating base 232 by an embedded injection method, and the first grounding shield 24”’ and the second grounding shield body 25a are in contact with the fixing section 236a of the grounding terminal 236.

[0186] In summary, the grounding shield 15 of the plug connector 1 of the present invention, together with the substrate 12, surrounds at least a portion of the plurality of signal conductive pads 122b on the mating plate portion 122 of the substrate 12. Furthermore, the first grounding shield 24, the second grounding shield 25, and the plurality of grounding terminals 236 of the socket connector 2 of the present invention together surround the plurality of signal terminals 235 of the terminal module 23. Moreover, when the plug connector 1 mates with the socket connector 2, the grounding terminals 236 of the socket connector 2 are electrically connected to the grounding shield 15, and each pair of signal terminals 235 of the socket connector 2 is electrically connected to a corresponding pair of signal conductive pads 122b. The grounding shield 15 covers and shields the free ends 235e of the plurality of signal terminals 235 or the free ends 235e of the plurality of signal terminals 235 to their contact portions 235f. Therefore, electromagnetic interference can be prevented from affecting signal transmission, enabling the connector to have high signal integrity at high transmission speeds.

[0187] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention.
