Description

[Technical field]

[0001] The invention relates to an electric connector, in particular to an electric connector component and an adapter which have improved shielding performance, reduced crosstalk interference and have a simple structure. [Background technology]

[0002] A known electrical connector is usually used as a carrier for transmitting electrical signals between cables and circuit boards of servers. For electrical connectors that transmit high-frequency signals, when high-frequency electrical signals are transmitted in the conductor of the electrical connector, electromagnetic radiation will be generated from the conductor to the outside and electromagnetic coupling will be generated with other conductors. This electromagnetic coupling will cause unwanted crosstalk interference between the conductors, affecting the integrity of signal transmission. Therefore, when designing electrical connectors, technicians in this field will simultaneously design grounding members between the conductors to reduce this unwanted crosstalk interference. However, due to the development of miniaturization of the structure, the grounding members in most current electrical connectors generally have their shielding parts on part of the main body of the conductor, which makes the shielding effect of the shielding members in current electrical connectors still unsatisfactory.

[0003] Therefore, it is necessary to design a new electrical connector assembly and adapter to overcome the above problems. [Summary of the invention]

[0004] In view of the problems faced by the background technology, one of the purposes of the present invention is to provide an electrical connector assembly with improved shielding performance, reduced crosstalk interference and simple structure. The combination of the main body of the shielding component and the pin of the electrical connector assembly enables a grounding shield to be formed on three sides of the signal conductive part. By utilizing the grounding shielding effect, while reducing the crosstalk between two rows of signal terminals, it is also possible to further reduce the near-crosstalk interference between other signal conductive parts in the same row and the near- and far-crosstalk interference of the signal conductive parts to other signal terminals, thereby achieving the purpose of improving the crosstalk shielding effect of the adapter using the electrical connector assembly.

[0005] In addition, another object of the present invention is to provide an adapter, in which the socket does not need to be designed with corresponding conductive terminals that match the conductive terminals on the plug, thereby shortening the contact transmission path of the electrical signal and further reducing crosstalk on the basis of the shielding effect of the main body and pins of the shielding component, thereby achieving the purpose of further improving the crosstalk shielding effect of the adapter.

[0006] To achieve the above purpose, the present invention adopts the following technical means:

[0010] Furthermore, the grounding conductive portion is higher than the signal conductive portion, and the position where the grounding conductive portion abuts against the pin is close to the end plate and away from the free end of the pin.

There are two second signal conducting parts between two adjacent second pins, and the two second signal conducting parts are respectively a pair of differential signal terminal structures.

[0014] Another scheme of the present invention is:

[0015] An adapter is used to be installed on a circuit board, the circuit board includes two rows of gold fingers, wherein the adapter includes a plug, a socket and a shielding member, the plug includes an insulating body and a plurality of conductive terminals, the plurality of conductive terminals are fixed in the insulating body in two rows and are electrically connected to the cable, each row of the plurality of conductive terminals includes a plurality of grounding terminals and a plurality of signal terminals, the grounding terminals have a grounding conductive portion, and the signal terminals have a signal conductive portion; the socket is used to be assembled on the circuit board, the socket has a plug-in cavity that is plugged and matched with the plug, and the two rows of gold fingers are exposed in the plug-in cavity; the shielding member has a main body portion arranged in the plug-in cavity, the main body portion has at least one end plate, and a plurality of pins extend from the end plate downward to contact the gold fingers;

[0016] When the plug is plugged into the socket, the two rows of conductive terminals are located on both sides of the main body, the grounding conductive part directly contacts the pin downward, the signal conductive part directly contacts the gold finger downward, and there is at least one signal conductive part between two adjacent pins.

[0017] Furthermore, each signal terminal has a signal base, which is bent and extended from the signal base to form a signal conductive portion, and each ground terminal has a ground base, which is bent and extended from the ground base to form a ground conductive portion. The signal base and the ground base are both arranged at a relative interval from the main body, and the bending and extending directions of the signal conductive portion and the ground conductive portion are consistent. The bending and extending direction of the signal conductive portion is opposite to the extending direction of the adjacent pin, and the ground conductive portion abuts the pin downward.

[0018] Furthermore, the end plate is bent from the main body, and is arranged at an angle to the main body. The end plate has a structural section facing the signal conducting part, and multiple pins extend from the structural section. Two adjacent pins and part of the structural section are arranged on three sides of at least one signal conducting part.

[0019] Furthermore, the end plate has a contact surface for abutting downward against the circuit board, the structural section is orthogonal to the normal of the contact surface, and the pins extend along the normal of the structural section and contact the gold fingers.

[0020] Furthermore, the pin has a contact surface and a conductive surface arranged opposite to the contact surface, the contact surface is used to contact the gold finger, and the ground conductive part contacts the conductive surface; along the direction toward the main body, the bent and raised end of the ground conductive part exceeds the bent and raised end of the signal conductive part.

[0021] Furthermore, each conductive terminal also includes a welding portion, a distance portion and a vertical portion, the welding portion is accommodated in the insulating body and welded to the cable, the distance portion is connected to the end of the welding portion away from the cable, one end of the vertical portion is connected to the distance portion, and the other end of the vertical section is connected to the signal base or the ground base; the distance portions on the two rows of conductive terminals extend downwardly in a direction away from each other, and the length of the signal base or the length of the ground base is greater than the length of the distance portions.

In addition, since the grounding conductive portion contacts the pin downward, the grounding conductive portion can be overlapped on the pin to form a shielding wall, so that the grounding conductive portion can block more crosstalk between the two signal conductive portions in the left and right directions.

[0025] The electrical signal in the cable of the adapter only needs to pass through the conductive terminal in the plug to directly contact the gold finger to transmit the electrical signal, that is, the socket does not need to be designed to match the conductive terminal on the plug, which shortens the contact transmission path of the electrical signal and further reduces the crosstalk on the basis of the shielding effect of the shielding component, thereby further improving the crosstalk shielding effect of the adapter. In addition, the shielding component of the adapter has a simple structure, and it also saves the design, production and assembly costs of the conductive terminal of the socket, which is obviously conducive to reducing the manufacturing cost of the product and reducing costs and increasing efficiency.

[0040]

[0041] [Specific implementation method]

[0042] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0043] In order to clearly and conveniently understand the technical solution of the present invention, the X-axis direction in the drawings of the specification is defined as the front-to-back direction, the Y-axis is defined as the left-to-right direction, and the Z-axis is defined as the up-down direction.

[0044] like Figures 1 to 4 As shown, the electrical connector assembly 100 of this embodiment is used to be assembled in a circuit board 800, and two rows of gold fingers 81 are provided on the circuit board 800. The electrical connector assembly 100 includes a plurality of conductive terminals 2, a shielding member 3 and an insulating body 51. The plurality of conductive terminals 2 are arranged in two rows and fixed to the insulating body 51. The shielding member 3 extends between the two rows of conductive terminals 2 and contacts the gold fingers 81.

[0045] The adapter 400 of this embodiment includes a plug 5, a socket 6 that is plugged and matched with the plug 5, and a shielding member 3. The two rows of conductive terminals 2 and the insulating body 51 of the electrical connector assembly 100 are designed as structural components to form a part of the structure of the plug 5, and the shielding member 3 of the electrical connector assembly 100 is assembled on the socket 6.

[0046] like Figures 5 to 7 As shown, based on the above, the plug 5 in this embodiment includes an insulating body 51, a shell body 52, two rows of conductive terminals 2 electrically connected to the cable 700, and locking members 53 assembled on two opposite sides of the shell body 52. ​​Among them, the insulating body 51 can be an insulating plastic formed in one piece and then assembled into the shell body 52, or it can be a structure in which a separate body is formed and then assembled into the shell body 52, and no excessive restrictions are made here.

[0047] The shell body 52 has a receiving cavity (not shown) for receiving and assembling the insulating body 51. Fig.10 As shown, the bottom of the shell body 52 is provided with a plurality of receiving grooves 521. In practical applications, each receiving groove 521 can be configured to receive one or a pair of conductive terminals 2. The receiving grooves 521 communicate with the receiving cavity. After the insulating body 51 is assembled in the receiving cavity of the shell body 52, the free end of the conductive terminal 2 exposed from the insulating body 51 is received in the receiving groove 521. Then, the bottom of the receiving groove 521 is opened so that the bottom of the conductive terminal 2 can be exposed from the opening of the receiving groove 521, so that the conductive terminal 2 can contact the gold finger 81 when the plug 5 is plugged into the socket 6. In addition, as shown in FIG. Figure 6 , Figure 7 and Fig. 9As shown, matching columns 522 are provided on both sides of the bottom of the shell body 52, and corresponding matching holes 82 are provided in the circuit board 800. When the plug 5 is matched with the socket 6, the matching columns 522 are located in the matching holes 82. The matching columns 522 and the matching holes 82 are matched to improve the matching stability of the plug 5 and the socket 6. Of course, in other embodiments, there can be other structures in the matching guide function, such as matching slide grooves between the plug 5 and the socket 6.

[0048] like Figure 1 , Figure 2 , Figure 7 , Fig.10 and Fig.11 As shown, in a specific structural form, the conductive terminal 2 includes a welding portion 24, a distance portion 25 and a vertical portion 26, wherein the welding portion 24 is fixed in the insulating body 51 and welded to the cable 700, and the distance portion 25 is formed by extending from the bottom of the welding portion 24. Specifically, the distance portions 25 of the two rows of conductive terminals 2 extend downwardly in an inclined manner away from each other, and the bottom of the distance portion 25 is connected to the vertical portion 26.

[0049] Based on the functional classification level, the plurality of conductive terminals 2 may include a plurality of ground terminals 21 and a plurality of signal terminals 22. Figure 1 , Figure 2 and Fig.11 As shown, each signal terminal 22 has a signal base 222 connected to the vertical portion 26, which is bent and extended from the signal base 222 to form a signal conductive portion 221, and the signal conductive portion 221 is used to contact the gold finger 81; Figure 2 and Fig.10 Each grounding terminal 21 has a grounding base 212 connected to the corresponding vertical portion 26, and is bent and extended from the grounding base 212 to form a grounding conductive portion 211. Specifically, the signal conductive portion 221 and the grounding conductive portion 211 have the same bending and extending direction. In this way, bending and extending along the same direction facilitates the grounding conductive portion 211 to isolate adjacent signal conductive portions 221, which is beneficial to improving the crosstalk shielding effect of the grounding conductive portion 211 on the signal conductive portion 221.

[0050] See also Figure 2 and Figure 7Based on the arrangement classification level, the multiple grounding terminals 21 include multiple first grounding terminals 21A arranged in a first row and multiple second grounding terminals 21B arranged in a second row, the multiple signal terminals 22 include multiple first signal terminals 22A arranged in a first row and multiple second signal terminals 22B arranged in a second row, the grounding conductive portion 211 includes a first grounding conductive portion 211A formed on the first grounding terminal 21A and a second grounding conductive portion 211B formed on the second grounding terminal 21B, the signal conductive portion 221 includes a first signal conductive portion 221A formed on the first signal terminal 22A and a second signal conductive portion 221B formed on the second signal terminal 22B, and the first signal conductive portion 221A and the second signal conductive portion 221B are both used to contact the gold finger 81.

[0051] like Figure 5 , Figure 8 and Fig.10 As shown, the socket 6 includes a seat body 62 and a shell 63. The shell 63 has a plurality of connection blocks 631. The connection blocks 631 are fixed in the circuit board 800. The fixing method can be plugging, welding, etc. In this embodiment, the specific fixing and installation structure between the connection blocks 631 and the circuit board 800 is not limited. The seat body 62 is assembled in the shell 63. The seat body 62 is formed with a plug-in cavity 61. Two rows of gold fingers 81 are exposed in the plug-in cavity 61. More specifically, a partition 621 is formed in the middle of the seat body 62 along the left and right directions of the Y axis. The partition 621 divides the plug-in cavity 61 into two chambers. Each chamber correspondingly exposes a row of gold fingers 81. When the plug 5 is plugged into the socket 6, the two rows of conductive terminals 2 of the plug 5 are respectively contacted and connected with the gold fingers 81 through the two chambers. Among them, the two side walls of the partition 621 are provided with assembly grooves 6211, and the assembly groove 6211 is provided with a top block 6212.

[0052] like Figure 3 and Figure 4 As shown, the shielding member 3 includes a main body 31, an end plate 32 and pins 33. In the adapter of this embodiment, the main body 31 is sleeved downward on the fence 621, the end plate 32 is bent from the main body 31 to form an angle between the end plate 32 and the main body 31, and the pins 33 are extended from the end plate 32 to form and abut against the gold finger 81 downward. Figure 1 and Figure 2As shown, the signal base 222 and the ground base 212 are both spaced apart from the main body 31, the bending extension direction of the signal conductive portion 221 is opposite to the extension direction of the adjacent pin 33, and the ground conductive portion 211 is downwardly abutted against the pin 33. At the same time, the end of the signal conductive portion 221 and the end of the ground conductive portion 211 are both bent and tilted upward to prevent the tilted end of the signal conductive portion 221 from scratching the gold finger 81 when the signal conductive portion 221 contacts, and to prevent the tilted end of the ground conductive portion 211 from scratching the pin 33.

[0053] like Figure 3 As shown, the main body 31 includes a first side plate 311, a second side plate 312 and a connecting plate 313, and the two ends of the connecting plate 313 are respectively connected to the top of the first side plate 311 and the top of the second side plate 312, and the first side plate 311 and the second side plate 312 are spaced apart, so that the first side plate 311 and the second side plate 312 are respectively closer to their respective corresponding conductive terminals 2, so as to further improve the shielding effect. And the first side plate 311 and the second side plate 312 are integrally connected to form the main body 31 through the connecting plate 313 at the top thereof, so that the main body 31 is formed into an arched structure with an opening at the bottom, so as to achieve the purpose of the main body 31 being downwardly sleeved on the partition 621, and in terms of production and manufacturing, the main body 31 can be directly formed by conventional processes such as stamping, cutting, bending, etc., with low manufacturing cost and easy production. Of course, in other embodiments, this structure of sequentially extending and forming may not be adopted. For example, the pin 33 can directly extend from the main body 31 to eliminate the structure of the end plate 32. In terms of connection method, this embodiment adopts an integral molding method. In other embodiments, the integral molding method may not be adopted, such as welding connection or fastener connection method.

[0054] Among them, Fig.12 and Fig.13As shown, in this embodiment, when the plug 5 is plugged into the socket 6, the distance between the connecting plate 313 and the circuit board 800 is greater than the maximum distance between the soldering portion 24 and the circuit board 800, that is, when the plug 5 is plugged into the socket 6, the first side plate 311 and the second side plate 312 extend along the Z direction to the top of the soldering portion 24. In general, the cable 700 will first expose the ground shielding layer (not shown), and then the ground shielding layer and the soldering portion 24 of the ground terminal 21 will be welded and connected. The wire core (not shown) used for transmitting signals in the cable 700 will extend along the cable 700 for a distance under the protection of the insulating layer of the cable 700, and then expose the insulating layer of the cable, and then be welded to the soldering portion 24 of the signal terminal 22. That is, when the plug 5 is plugged into the socket 6, the welding portion of the wire core of the cable 700 and the signal terminal 22 will be lower than the welding portion of the ground shielding layer of the cable 700 and the ground terminal 21. In this case, in this embodiment, when the plug 5 is plugged into the socket 6, the welding portion of the wire core of the cable 700 and the signal terminal 22 will be lower than the welding portion of the ground shielding layer of the cable 700 and the ground terminal 21. In this case, in this embodiment, when the plug 5 is plugged into the socket 6, the welding portion of the wire core of the cable 700 and the signal terminal 22 will be lower than the welding portion of the ground shielding layer of the cable 700 and the ground terminal 21. When the socket 6 is used, by setting the height of the first side plate 311 and the second side plate 312 to be higher than the welding portion 24 of the grounding terminal 21, the exposed wire cores and the welding portions 24 of the signal terminals 22 on both sides of the shielding component 3 can be isolated by the main body 31, thereby achieving the effect of reducing the crosstalk interference generated between the two rows of wire cores and between the welding portions 24 of the two rows of signal terminals 22. Only one shielding component 3 is needed to achieve the purpose of shielding the crosstalk interference from the exposed wire core of the cable 700 to the gold finger 81. The structure is simple and the effect is obvious. In practical applications, it can also achieve the purpose of saving the design of a shielding structure on the plug 5, thereby reducing costs and increasing efficiency.

[0055] In addition, if Figure 3 , Figure 8 and Fig.11 As shown, the first side plate 311 and the second side plate 312 are both provided with a through hole 314. More specifically, an elastic sheet 315 extends upward from the hole wall of the through hole 314. When the main body 31 is downwardly sleeved on the partition 621, the elastic sheet 315 enters the assembly groove 6211 and is located below the support block 6212. In this way, the main body 31 of the shielding component 3 is buckled onto the socket 6. At the same time, the pin 33 is welded to the gold finger 81 through the contact surface 331. In this way, the assembly stability of the socket 6 on the circuit board 800 can be further improved.

[0056] In addition, if Figure 3As shown, along the left and right directions of the Y-axis, the through holes 314 located on the first side plate 311 and the through holes 314 located on the second side plate 312 are staggered. In this way, the problem of electromagnetic radiation leakage caused by the formation of a through hole penetrating the main body 31 along the front-to-back direction of the X-axis between the first side plate 311 and the second side plate 312 can be avoided. Therefore, a plurality of staggered through holes 314 and elastic sheets 315 are arranged in the main body 31, which can achieve the purpose of both ensuring the assembly stability of the shielding component 3 on the socket 6 and ensuring the shielding effect.

[0057] like Figure 2 , Figure 3 and Figure 4 As shown, the end plate 32 has a structural section 321 and a contact surface 322, the structural section 321 and the contact surface 322 are orthogonal to each other, and the pin 33 extends along the normal direction of the structural section 321, the contact surface 322 is used to abut the circuit board 800 downward, and the structural section 321 faces the signal conductive portion 221. Figure 2 , Figure 3 , Figures 10 to 13 As shown, in a more specific structure, the end plate 32 includes a first end plate 323 and a second end plate 324. The first end plate 323 is formed by bending and extending from the bottom of the first side plate 311 toward the first signal terminal 221, and the second end plate 324 is formed by bending and extending from the bottom of the second side plate 312 toward the second signal terminal 222.

[0058] In addition, in actual applications, with respect to the assembly stability of the shielding component 3 on the circuit board 800, for the main body 31 whose side wall surface is perpendicular to the surface of the circuit board 800, the angle between the contact surface 322 of the end plate 32 and the side wall surface of the main body 31 is defined as the bending angle. Obviously, the most ideal condition for assembly stability is that the bending angle between the main body 31 and the end plate 32 is exactly 90°, because in this case, there is surface contact between the end plate 32 and the circuit board 800, which can ensure that the contact surface 322 of the end plate 32 can fully abut against the surface of the circuit board 800. However, in actual manufacturing, there are often certain manufacturing process errors, and it is difficult to achieve a bending angle of exactly 90°, which will cause the bending angle between the main body 31 and the end plate 32 to be less than 90° or greater than 90°. In this case, before the shielding member 3 is placed on the circuit board 800 for assembly, the pins 33 extending normally from the end plate 32 will extend upwardly (when the bending angle is less than 90°), or the pins 33 extending normally from the end plate 32 will extend downwardly so that the end plate 32 is lifted and does not contact the surface of the circuit board 800 (when the bending angle is greater than 90°). In these two cases, If the shielding component 3 is to be stably assembled in a manner to ensure that the pin 33 is in full surface contact with the gold finger 81 and that the end plate 32 is in full surface contact with the surface of the circuit board 800, internal stress will inevitably be generated at the connection between the end plate 32 and the pin 33 and at the connection between the end plate 32 and the main body 31. This internal stress will obviously resist the above-mentioned assembly combination method of full surface contact between the end plate 32 and the circuit board 800 and the pin 33 and the gold finger 81. That is to say, the internal stress generated at the connection between the end plate 32 and the pin 33 and at the connection between the end plate 32 and the main body 31 will reduce the combination stability of the shielding component 3 and the circuit board 800.

[0059] Therefore, based on the above specific situation, in this embodiment, if Figures 2 to 4As shown, the position where the grounding conductive portion 211 abuts against the pin 33 is close to the end plate 32 and away from the free end of the pin 33 . In this case, compared to abutting against the free end of the pin 33, when the grounding conductive portion 211 abuts against the pin 33 downward in a manner close to the end plate 32, the position where the abutting force of the grounding terminal 21 on the pin 33 will act will be closer to the connection between the main body 31 and the end plate 32, and closer to the connection between the end plate 32 and the pin 33. In this way, the abutting force of the grounding conductive portion 211 on the pin 33 can also serve to offset or reduce the internal stress at the connection between the end plate 32 and the main body 31 and the internal stress at the connection between the end plate 32 and the pin 33, thereby achieving the purpose of reducing or eliminating the adverse effect of the internal stress on the bonding stability between the shielding component 3 and the circuit board 800. That is, the position where the grounding conductive portion 211 abuts against the pin 33 is close to the end plate 32, which will be beneficial to pressing the end plate 32 against the surface of the circuit board 800, while ensuring the bonding stability of the pin 33 on the gold finger 81, thereby achieving the purpose of improving the assembly stability of the shielding component 3 on the circuit board 800.

[0060] For details, see Figures 2 to 4 The pin 33 has a contact surface 331 and a conductive surface 332 arranged opposite to the contact surface 331. The contact surface 331 is used to contact the gold finger 81 downward, and the conductive surface 332 is used to contact and conduct with the ground conductive portion 211. Since the contact surface 331 and the conductive surface 332 are arranged opposite to each other, and the signal conductive portion 221 is directly in contact with the gold finger 81, after the conductive terminal 2 is connected to the gold finger 81, along the Z direction, the ground conductive portion 211 will be higher than the signal conductive portion 221. At the same time, the curvature of the ground terminal 21 when abutting against the pin 33 will also be greater than the curvature of the signal terminal 22 when abutting against the gold finger 81. In this way, the position where the ground conductive portion 211 abuts against the pin 33 will be further close to the end plate 32 and away from the free end of the pin 33, thereby achieving the purpose of further improving the assembly stability of the shielding component 3 on the circuit board 800. In addition, the grounding conductive portion 211 is stacked on the pin 33. When the plug 5 is plugged into the socket 6, the grounding conductive portion 211 of the grounding terminal 21 will first contact the pin 33, so that the entire shielding component 3 will be grounded first to form a grounding shield, and then the signal terminal 22 will contact and conduct with the gold finger 81. This can reduce the crosstalk interference generated between the signal terminals 22 at the moment of connection.

[0061] For more specific structures, see Figure 2 , Figure 3 , Figures 10 to 13, the pin 33 includes a first pin 33A and a second pin 33B. The first pin 33A is formed by extending from the normal direction of the first end plate 323 and contacts the gold finger 81 downwards, and the first grounding conductive portion 211A contacts the first pin 33A downwards; the second pin 33B is formed by extending from the normal direction of the second end plate 324 and contacts the gold finger 81 downwards, and the second grounding conductive portion 211B contacts the second pin 33B downwards. It can be seen that the first pin 33A of the first side plate 311 contacts the gold finger 81, and at the same time, the second pin 33B of the second side plate 312 connected to the first side plate 311 is also connected to the corresponding gold finger 81. In this way, in terms of electrical performance, it is conducive to forming a stable grounding shield between the two rows of gold fingers 81, that is, the integrally formed shielding component 3 can play the role of connecting all the grounding conductive portions 211, increase the grounding loop, and improve the stability of the grounding level, so as to further improve the shielding effect. Specifically, in this embodiment, there are two first signal conducting portions 221A between two adjacent first pins 33A, and there are two second signal conducting portions 221B between two adjacent second pins 33B. That is, in practical applications, there are two first signal conducting portions 221A between two adjacent first pins 33A, and the two first signal conducting portions 221A are respectively a pair of differential signal terminals for transmitting differential signals, and there are two second signal conducting portions 221B between two adjacent second pins 33B, and the two second signal conducting portions 221B are respectively a pair of differential signal terminals for transmitting differential signals.

[0062] In summary, the present invention has the following beneficial effects:

[0063] 1. By arranging a shielding member 3 between two rows of conductive terminals 2, an end plate 32 is provided near the grounding conductive portion 211 in the main body 31 of the shielding member 3, and a plurality of pins 33 conductive with the grounding terminal 21 are extended from the end plate 32, and a signal conductive portion 221 is provided between two adjacent pins 33, so that the shielding member 3 can be arranged around three sides of the signal conductive portion 221 to block the radiation of the signal to form a shield, that is, the Y-direction left side, the Y-direction right side and the side close to the end plate 32 of the same row of conductive terminals 2, so that the pins 33 play a role in shielding the two rows of conductive terminals 2. The shielding effect of the near-end crosstalk between the signal conductive parts 221, the shielding effect of the main body 31 and the end plate 32 on the near-end crosstalk between the two rows of signal conductive parts 221; at the same time, since the electromagnetic radiation is radiated in the form of divergence toward the space, for the conductive terminals 2 located in the two rows, the main body 31 extends between the two rows of conductive terminals 2, which makes it possible to form at least a grounding shield composed of the main body 31 between the two rows of signal terminals 22, thereby achieving the purpose of shielding the undesirable near-end and far-end crosstalk generated between the two rows of signal terminals 22. In addition, since the ground conductive part 211 contacts the pin 33 downward, the ground conductive part 211 can be overlapped with the pin 33 to form a shielding wall, so that the ground conductive part 211 can block more crosstalk between the two signal conductive parts 221 in the left and right directions of the Y direction.

[0064] 2. Since the end plate 32 and the main body 31 are arranged at an angle, and two adjacent pins 33 and a partial structural section 321 are arranged on three sides of at least one signal conductive portion 221, the left side, right side and structural section 321 of the same row of conductive terminals 2 all play a shielding role in near-end crosstalk.

[0065] 3. The structural section 321 is orthogonal to the contact surface 322, and the contact surface 322 abuts against the surface of the circuit board 800, so that the structural section 321 can face the signal conductive part 221 in a form perpendicular to the surface of the circuit board 800, and the pin 33 extends along the normal direction of the structural section 321 and contacts the gold finger 81, and at the same time, the signal conductive part 221 contacts the gold finger 81 on the surface of the circuit board 800, so that the signal conductive part 221 can be in the surrounding area formed between the structural section 321 and two adjacent pins 33. The contact surface 322 is in contact with the circuit board 800, which can ensure that the end plate 32 is in contact with the circuit board 800 and eliminate the gap between them, so as to avoid electromagnetic radiation from passing through the gap between the end plate 32 and the circuit board 800 and causing crosstalk interference to the two rows of conductive terminals 2, so that the radiation signal between the two rows of conductive terminals 2 is also more comprehensively shielded by the end plate 32.

[0066] 4. The grounding conductive part 211 is higher than the signal conductive part 221. Since the grounding conductive part 211 contacts the pin 33 downward, the grounding conductive part 211 can be stacked on the pin 33 to form a shielding wall, so that the grounding conductive part 211 can block more crosstalk between the two signal conductive parts in the left and right directions. And the position where the grounding conductive part 211 abuts against the pin 33 is close to the end plate 32 and away from the free end of the pin 33. In this way, compared with abutting against the free end of the pin 33, the position where the grounding terminal 21 acts on the pin 33 will be closer to the main body.

[0067] The connection between the end plate 31 and the end plate 32, and the connection between the end plate 32 and the pin 33 is closer. In this way, the abutting force of the grounding conductive part 211 on the pin 33 can also play a role in offsetting or reducing the internal stress at the connection between the end plate 32 and the main body 31 and the internal stress at the connection between the end plate 32 and the pin 33, thereby achieving the purpose of reducing or eliminating the adverse effect of the internal stress on the bonding stability between the shielding component 3 and the circuit board 800. That is, the position where the grounding conductive part 211 abuts against the pin 33 is close to the end plate 32, which will be beneficial to pressing the end plate 32 to the surface of the circuit board 800, improving the bonding stability of the pin 33 on the gold finger 81, and ensuring the assembly stability of the shielding component 3 on the circuit board 800.

[0068] 5. The bending extension direction of the signal base 222 forming the signal conductive part 221 of the two rows of conductive terminals 2 is opposite to the extension direction of the pin 33, so that when the plug 5 and the socket 6 are plugged and matched, the ground conductive part 211 and the signal conductive part 221 will be closer to the main body 31 and the end plate 32 due to the crimping. In addition, because the structure of the signal base 222 forming the signal conductive part 221 is designed to be bent and tilted upward, the tilted end of the signal conductive part 221 can form a structural form facing the main body 31. When the conductive terminal 2 abuts against the gold finger 81, the signal conductive part

[0069] The tilted end of the end 221 will be close to the main body 31. In this way, compared with other structural forms in which the tilted end is not facing the main body, the strong electromagnetic radiation generated by the tilted end of the signal conductive part 221 of the signal terminal 22 due to the antenna effect can be shielded as much as possible by the main body 31, so that the main body 31 can also play a role in reducing the crosstalk interference of the tilted end of the signal conductive part 221 to other conductive terminals 2 due to the antenna effect. This structural design form in which the tilted ends of the signal conductive parts 221 of the two rows of conductive terminals 2 are close to each other and bent upward can achieve the purpose of shielding the electromagnetic radiation of the tilted ends as much as possible only through the main body 31 in the shielding member 3, without the need to design other shielding structures 3 to specifically shield the structure of the tilted ends. Therefore, this structural design form of the conductive terminal 2 can also play a role in further saving the cost of structural design.

[0070] 6. At the same time, the contact surface 331 of the pin 33 is arranged opposite to the conductive surface 332, and the contact surface 331 of the ground terminal 21 and the pin 33 will be higher than the contact position between the signal terminal 22 and the gold finger 81. When the conductive terminal 2 abuts against the gold finger 81 downward, the curvature of the ground base 212 will become larger, which will make the tilted end of the ground conductive portion 211 exceed the tilted end of the signal conductive portion 221 in the direction toward the main body 31, that is, the tilted end of the ground conductive portion 211 and the main body 31 are The distance is smaller than the distance between the raised end of the signal conductive portion 221 and the main body 31, so that the raised end of the ground conductive portion 211 can form more shielding between the raised ends of the signal conductive portion 221. Therefore, the ground conductive portion 211 can also further shield the electromagnetic radiation generated by the raised end of the signal conductive portion 221 due to the antenna effect, so as to reduce the crosstalk interference of the raised end of the signal conductive portion 221 to the adjacent or opposite rows of signal terminals 22, so as to achieve the purpose of further improving the shielding effect.

[0071] 7. The electrical signal in the cable 700 in the adapter 400 can directly contact the gold finger 81 through the conductive terminal 2 in the plug 5 to transmit the electrical signal, that is, the socket 6 does not need to be designed with a conductive terminal that matches the conductive terminal 2 on the plug 5, which shortens the contact transmission path and the number of contact nodes of the electrical signal, and further reduces the crosstalk on the basis of the shielding effect of the shielding member 3, thereby further improving the crosstalk shielding effect of the adapter 400. In addition, the shielding member 3 of the adapter 400 has a simple structure, and also saves the design, production and assembly costs of the conductive terminal of the socket 6, which is obviously conducive to reducing the manufacturing cost of the product and reducing costs and increasing efficiency.

[0072] 8. The distance portions 25 between the two rows of conductive terminals 2 are arranged to be away from each other, so that the distance between the distance portions 25 of the two rows of conductive terminals 2 and the distance between the vertical portions 26 of the two rows of conductive terminals 2 are both increased, thereby reducing the mutual capacitance and inductance between them, so as to achieve the purpose of adjusting impedance and optimizing signal transmission effect.

[0073] When the length of the signal base 222 is greater than the length of the away portion 25, the raised end of the conductive terminal 2 can be as far away from the vertical portion 26 and the away portion 25 as possible, so as to reduce the crosstalk interference of the raised end to the vertical portion 26 and the away portion 25 due to the antenna effect.

[0074] 9. The main body 31 is downwardly sleeved on the fence 621, and the pins 33 of the main body 31 are welded to the gold fingers 81. In this way, the structural stability of the socket 6 when assembled on the circuit board 800 can be improved.

[0075] In other words, the main body 31 formed by the shielding member 3 can not only enhance the crosstalk shielding effect of the adapter 400 , but also enhance the bonding strength between the socket 6 and the circuit board 800 .

[0076] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
