Storage devices may be connected via a high-speed connector, for example, via a SAS (serial attached SCSI) connector. In addition, the NIC of the computing device 1000 may be connected to a local area network via a high-speed connector.

[0070] It should be noted that a high-speed connector refers to an electrical connector with a high operating frequency. For example, the operating frequency of a high-speed connector can reach several hundred MHz (megahertz) or even several GHz (gigahertz). A high-speed connector can be used to transmit high-speed signals, wherein a high-speed signal refers to a signal with a frequency greater than 50 MHz.

[0071] When one server communicates with another server, the two can communicate via a high-speed network card, wherein a high-speed connector is provided on the high-speed network card, that is, the two servers can be connected via the high-speed connector for communication.

[0072] In a data center, a cabinet may be provided with multiple servers, and the multiple servers may be connected to a switch, and any two servers may be connected via the switch. For example, the switch and the server may be connected via a high-speed connector.

[0073] In addition, in order to increase bandwidth, data centers use network port aggregation technology, in which multiple low-speed network ports are aggregated into a high-speed connector.

[0074] In summary, high-speed connectors are widely used in the field of computing devices.

[0075] According to different functions and uses, high-speed connectors can be divided into multiple types, such as HDMI (high definition multimedia interface) connector, USB (universal serial bus) connector, SATA (serial advanced technology attachment, serial ATA) connector, SAS connector and PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) connector and SAS connector. Among them, there are many types of high-speed connectors, which are not listed here one by one.

[0076] According to the types of two devices connected by the high-speed connector, high-speed connectors can be divided into multiple types, such as orthogonal connectors, direct orthogonal connectors, parallel board connectors, standard connectors and plug-in card connectors.

[0077] In addition to the computing device 1000, in industrial automation and medical equipment, the high-speed connector can also be used to connect sensors, actuators and other devices to achieve real-time data collection and control.

The isolating member 1302 may support the signal transmission circuit board 1031, and allow the signal transmission circuit board 1031 to be spaced apart from the shielding member 1303 in the adjacent transmission component 103, thereby avoiding a short circuit between the signal transmission circuit board 1031 and the shielding member 1303 in the adjacent transmission component 103. In addition, the shielding member 1303 may electromagnetically shield the signal transmission circuit board 1031, thereby avoiding mutual interference between the signals transmitted on the signal transmission circuit boards 1031 in two adjacent transmission components 103.

[0087] A ground signal transmission element includes a ground trace 150 and a ground connection terminal 170 and a ground docking terminal 190 respectively connected to two ends of the ground trace 150 .

[0088] Among them, a differential signal transmission component is used to transmit a pair of differential signals, and two differential signal transmission components are used to transmit two differential sub-signals with the same amplitude and opposite phases. The ground signal transmission component is used to transmit the ground signal.

[0089] A differential signal transmission element is disposed between two adjacent differential signal transmission components, thereby achieving electromagnetic shielding between the two adjacent differential signal transmission components, thereby avoiding mutual interference between differential signals transmitted by the two adjacent differential signal transmission components.

[0091] Please refer again Figure 2 When the high-speed connector 100 is a female connector 101, the high-speed connector 100 may be approximately rectangular. For example, the high-speed connector 100 may include a first mating surface 111, and a plurality of accommodating cavities may be provided on the first mating surface 111, and a connection terminal (such as a differential connection terminal 160 and a ground connection terminal 170) may be provided in one accommodating cavity, wherein two differential connection terminals 160 in a differential signal transmission component may be respectively provided in two adjacent accommodating cavities.

The plurality of pins 130 may be respectively plugged into a plurality of accommodating cavities of the female connector 101, so that they may be respectively docked and electrically connected with the plurality of connection terminals of the female connector 101. The pins serving as the differential connection terminals 160 may be docked with the differential connection terminals 160 of the female connector 101, and the pins serving as the ground connection terminals 170 may be docked with the ground connection terminals 170 of the female connector 101.

[0094] Among them, by setting a ground signal transmission member between two adjacent differential signal transmission components, electromagnetic shielding between the two adjacent differential signal transmission components can be achieved. However, in this electromagnetic shielding method, the electromagnetic shielding effect between the two adjacent differential signal transmission components is poor, so the signal loss is large.

[0099] For example, the first signal module 300 is in a strip shape, the electromagnetic shielding cavity 330 is in a strip shape, the electromagnetic shielding cavity 330 extends in the same direction, and the two ends of the electromagnetic shielding cavity 330 are respectively located at the first connection end 301 and the second connection end 302 of the first signal module 300 .

[0100] For example, the first signal terminal can be disposed at the first connection end 301, and the second signal terminal can be disposed at the second connection end 302. The first signal terminal can be electrically connected to the pin on the first circuit board 400, and the second signal terminal can be electrically connected to the first signal pin of the male connector.

[0103] The first signal module 300 may be in a columnar shape. In this case, in the female connector 200 , the first connection end 301 and the second connection end 302 of the first signal module 300 may face opposite directions respectively.

[0104] In some examples, the middle of the first signal module 300 is bent. The first signal module 300 may include a first transmission segment 303 and a second transmission segment 304, wherein one end of the first transmission segment 303 may be connected to the first circuit board 400, and at this time, one end of the first transmission segment 303 connected to the first circuit board 400 may serve as the first connection end 301.

[0106] The extension direction of the first transmission section 303 intersects with the extension direction of the second transmission section 304, and a preset angle may be formed between the extension direction of the first transmission section 303 and the extension direction of the second transmission section 304. For example, the first transmission section 303 is perpendicular to the second transmission section 304, and in this case, the preset angle is equal to 90°. In addition, the angle between the first transmission section 303 and the second transmission section 304 may be equal to 60° or 120°. In the embodiment of the present application, the value of the preset angle is not limited, and the preset angle between the first transmission section 303 and the second transmission section 304 may be set according to the requirements.

[0107] Among them, the first transmission sections 303 of the multiple first signal modules 300 are located in the same plane at one end away from the second transmission section 304 (ie, the first connection end 301), so as to facilitate the electrical connection between the connector female head 200 and the first circuit board 400 or other structures.

[0108] The second transmission segments 304 of the plurality of first signal modules 300 are located in the same plane at one end (the second connection end 302 ) away from the first transmission segment 303 , thereby facilitating electrical connection between the female connector 200 and the male connector or other structures.

[0109] In some examples, the plurality of first signal modules 300 may be arranged in a plurality of rows, a row of first signal modules 300X may include a plurality of first signal modules 300, and the plurality of first signal modules 300 in a row of first signal modules 300X may be arranged in sequence along the first direction X. Figure 5 In the example, the first direction X is a direction perpendicular to the paper and inward. Figure 6 A row of first signal modules 300X may include 2, 3, 4, or even more first signal modules 300. Figure 6 In the figure, a row of first signal modules 300X including four first signal modules 300 is taken as an example to illustrate the structure of the connector female head 200 provided in the embodiment of the present application.

[0110] For example, the female connector 200 may include 2, 3, 4, and 5 rows of first signal modules 300X. Figure 5 In the figure, the structure of the connector female head 200 provided in the embodiment of the present application is illustrated by taking the 3-row first signal module 300X as an example.

[0111] A plurality of rows of first signal modules 300X may be arranged in sequence along the second direction Y. Figure 5 As shown, the direction indicated by the arrow Y is the second direction Y, wherein the second direction Y may be perpendicular to the first direction X, and when the female connector 200 is connected to the first circuit board 400, both the first direction X and the second direction Y may be parallel to the first circuit board 400. The arrangement direction of the multiple rows of first signal modules 300X refers to the arrangement direction of the first transmission segments 303 of the first signal modules 300 in the multiple rows of first signal modules 300X.

[0112] For example, the plurality of rows of first signal modules 300X include a first row of first signal modules 300X1, a second row of first signal modules 300X2 and a third row of first signal modules 300X3.

[0113] Orthographic projections of a plurality of first signal modules 300 in a row of first signal modules 300X in the first direction X may be arranged to overlap.

[0114] In some examples, the number of first signal modules 300 included in each row of first signal modules 300X may be equal.

[0115] The plurality of first signal modules 300 may be divided into a plurality of categories according to their sizes, and the plurality of first signal modules 300 included in a row of first signal modules 300X may be of the same category.

[0116] For example, the plurality of first signal modules 300 may include a first type signal module 305, a second type signal module 306, and a third type signal module 307, wherein the sizes of the first type signal module 305, the second type signal module 306, and the third type signal module 307 are reduced in sequence, and at this time, the length of the first transmission segment 303 of the first type signal module 305, the length of the first transmission segment 303 of the second type signal module 306, and the length of the first transmission segment 303 of the third type signal module 307 are reduced in sequence. The length of the second transmission segment 304 of the first type signal module 305, the length of the second transmission segment 304 of the second type signal module 306, and the length of the second transmission segment 304 of the third type signal module 307 are reduced in sequence.

[0117] The first row of first signal modules 300X1 may include multiple first-type signal modules 305 , the second row of first signal modules 300X2 may include multiple second-type signal modules 306 , and the third row of first signal modules 300X3 may include multiple third-type signal modules 307 .

[0118] Among two adjacent rows of first signal modules 300X, the orthographic projection of one row of first signal modules 300X on the reference plane may be located within the orthographic projection of the other row of first signal modules 300X on the reference plane.

[0119] For example, the orthographic projection of the third type signal module 307 on the reference plane is located within the orthographic projection of the second type signal module 306 on the reference plane; the orthographic projection of the second type signal module 306 on the reference plane is located within the orthographic projection of the first type signal module 305 on the reference plane. In this way, the first connection ends 301 of multiple rows of first signal modules 300X can be located on the same plane, and the second connection ends 302 can be located on the same plane.

[0120] Please continue reading Figure 7, the number of electromagnetic shielding cavities 330 is greater than or equal to 2. For example, the number of electromagnetic shielding cavities 330 may be 3, 4, 5, 6, 7, 8, or even more. In the embodiment of the present application, the number of electromagnetic shielding cavities 330 is not limited. Figure 6 In the embodiment of the present application, the structure of the first signal module 300 provided in the embodiment of the present application is introduced by taking the first signal module 300 including four electromagnetic shielding cavities 330 as an example.

[0121] Among them, multiple first signal transmission components 320 can be respectively arranged in multiple electromagnetic shielding cavities 330. At this time, the first signal transmission components 320 correspond to the electromagnetic shielding cavities 330 one by one. In other words, the number of first signal transmission components 320 can be the same as the number of electromagnetic shielding cavities 330.

[0122] The electromagnetic shielding cavity 330 has the function of electromagnetic shielding, and the electromagnetic shielding cavity 330 can surround the first signal transmission component 320, thereby improving the electromagnetic shielding effect between two adjacent first signal transmission components 320, thereby reducing the loss of the signal transmitted on the first signal transmission component 320, and improving the signal-to-noise ratio, thereby improving the quality of the signal transmitted on the first signal transmission component 320.

[0123] In different scenarios, the signals transmitted by the connector female head 200 are different. At this time, the number of signals transmitted by the connector female head 200 is different. The embodiment of the present application can determine the number of first signal modules 300 of the connector female head 200 used in the scenario according to the number of signals transmitted by the connector female head 200, so that the connector female head 200 can transmit a corresponding number of signals. The connector female head 200 provided in the embodiment of the present application is composed of a plurality of first signal modules 300. By adjusting the number of first signal modules 300 set in the connector female head 200 in different scenarios, the connector female head 200 can be applied to different scenarios to transmit different signals. Therefore, the first signal module 300 has high versatility and high repeatability, thereby reducing the complexity of the connector female head 200.

[0124] In addition, different types of female connectors 200 can be made of different numbers of first signal modules 300 , thereby reducing the research and development cost of the female connector 200 .

[0130] Among them, the multiple first signal transmission components 320 can all be arranged on the cavity wall of the electromagnetic shielding cavity 330.

[0131] Alternatively, the plurality of first signal transmission components 320 may be disposed in the electromagnetic shielding cavity 330 and not connected to the cavity wall. In this case, the first signal transmission components 320 may be connected to the cavity wall of the electromagnetic shielding cavity 330 via a connector.

[0132] Alternatively, part of the first signal transmission component 320 can be disposed on the cavity wall of the electromagnetic shielding cavity 330 , while another part of the first signal transmission component 320 can be disposed in the electromagnetic shielding cavity 330 , and both are not connected to the cavity wall of the electromagnetic shielding cavity 330 .

[0133] See also Figure 7 and Figure 8 In this embodiment, the first signal module 300 may further include a support tube 311 and an inner partition 312, both of which include an electromagnetic shielding layer, and the inner partition 312 is disposed in the support tube 311 to divide the inner cavity of the support tube 311 into a plurality of electromagnetic shielding cavities 330 extending axially along the support tube 311. The inner cavity of the support tube 311 refers to a cavity surrounded by the inner wall of the support tube 311.

[0134] The cross section of the support tube 311 may be circular or elliptical.

[0135] The inner partition 312 may extend inside the support tube 311 , and the inner partition 312 may extend from one end of the support tube 311 to the other end of the support tube 311 .

[0136] The support tube 311 has a simple structure and is easy to manufacture.

[0137] See you later Figure 5 , and combined with Figure 7 The support tube 311 may include a first tube segment and a second tube segment, one end of the first tube segment may be connected to the first circuit board 400, and the other end may be connected to the second tube segment, and the end of the second tube segment away from the first tube segment may accommodate a partial structure of the connector male head.

[0142] Fig. 9 is another cross-sectional view of the first signal module 300 according to some embodiments.

[0143] See also Fig. 9 When the first signal transmission component 320 is disposed on the cavity wall of the electromagnetic shielding cavity 330 , the first signal transmission component 320 may also be disposed on the inner partition 312 .

[0144] See also Figures 7 to 9, two adjacent electromagnetic shielding cavities 330 are separated by an inner partition 312, the surface of the inner partition 312 can be used as the cavity wall of the electromagnetic shielding cavity 330, the support tube 311 and the inner partition 312 both include an electromagnetic shielding layer, therefore, the electromagnetic shielding cavity 330 surrounded by the support tube 311 and the inner partition 312 can have electromagnetic shielding characteristics, therefore, the electromagnetic shielding cavity 330 can provide electromagnetic shielding for the first signal transmission component 320 arranged in the electromagnetic shielding cavity 330, thereby reducing interference between the first signal transmission components 320 arranged in two adjacent electromagnetic shielding cavities 330.

[0145] In one first signal module 300 , the cross-sectional areas of the plurality of electromagnetic shielding cavities 330 may be the same. Of course, the cross-sectional areas of the plurality of electromagnetic shielding cavities 330 may be the same.

[0146] See also Figures 7 to 9 In some examples, the inner partition 312 may include a plurality of partitions 340 , wherein the first ends 341 of the plurality of partitions 340 are connected to each other, and the second ends 342 of the plurality of partitions 340 are spaced apart, and the second ends 342 of the plurality of partitions 340 may be connected to the inner wall of the support tube 311 .

[0147] The first ends 341 of the plurality of partitions 340 may be located in the middle of the support tube 311 .

[0148] For example, in the cross section of the first signal module 300, along the first designated direction F1, the thickness of the partition 340 gradually decreases, wherein the direction from the first end 341 of the partition 340 to the second end 342 of the partition 340 is the first designated direction F1, and the thickness of the partition 340 refers to the width of the partition 340 in the second designated direction F2, wherein in the cross section of the inner partition 312, the second designated direction F2 is perpendicular to the first designated direction F1. Figure 7 As shown, the direction indicated by arrow F1 is the first designated direction F1, and the direction indicated by arrow F2 is the second designated direction F2. It can be understood that different partitions 340 correspond to different first designated directions F1, and different partitions 340 correspond to different second designated directions F2.

[0149] For example, the number of the partitions 340 may be 2, 3, 4, 5, or even more, wherein the number of the partitions 340 may be set according to requirements. Figures 7 to 9 Taking the example that the inner partition 312 includes four partitions 340 , the structure of the inner partition 312 provided in the embodiment of the present application is illustrated. In the embodiment of the present application, the number of the partitions 340 is not limited.

[0150] Fig.10is another cross-sectional view of the first signal module 300 according to some embodiments.

[0151] See also Fig.10 In some other examples, along the first designated direction F1 , the thickness of the partition 340 remains constant.

[0152] Please continue reading Figures 7 to 10 In this embodiment, the inner partition 312 includes a partition frame 3121 and a first electromagnetic shielding layer 3122. The partition frame 3121 is connected to the inner surface of the support tube 311 and divides the inner cavity of the support tube 311 into a plurality of electromagnetic shielding cavities 330. The first electromagnetic shielding layer 3122 covers the surface of the partition frame 3121. The first electromagnetic shielding layer 3122 is the electromagnetic shielding layer included in the inner partition 312.

[0153] The separation frame 3121 may be made of insulating materials, such as ceramics, plastics, and the like.

[0154] The separation frame 3121 can play a supporting role, and can support the first electromagnetic shielding layer 3122, wherein the first electromagnetic shielding layer 3122 covers the surface of the separation frame 3121, so that the inner partition 312 has the characteristic of electromagnetic shielding.

[0155] For example, the first electromagnetic shielding layer 3122 may be made of a conductive material, such as a conductive adhesive material, or a metal material such as copper or silver.

[0156] By covering the outer surface of the partition frame 3121 with the first electromagnetic shielding layer 3122 , the inner partition 312 can have the characteristic of electromagnetic shielding.

[0157] The first electromagnetic shielding layer 3122 may be formed on the outer surface of the separation frame 3121 by a deposition or electroplating process.

[0158] In some examples, the first signal module 300 may further include a first grounding terminal, which is electrically connected to the first electromagnetic shielding layer 3122 and is located at one end of the first electromagnetic shielding layer 3122. For example, the first grounding terminal may be located at the first connection end 301 (e.g. Figure 5 Wherein, the first ground terminal can be used to connect to the first circuit board 400 (as shown in FIG. Figure 6 The first electromagnetic shielding layer 3122 is connected to the ground terminal on the first electromagnetic shielding layer 3122, so that the first electromagnetic shielding layer 3122 can receive the ground signal. The number of the first grounding terminals can be one or more, and in the embodiment of the present application, the number of the first grounding terminals is not limited.

[0159] In the embodiment of the present application, the first ground terminal may be provided only at the first connection end 301 (eg, Figure 5 As shown), therefore, the number of first grounding terminals in the connector female head 200 can be reduced.

[0160] The partition skeleton 3121 may include a plurality of sub-partitions, one end of each of the plurality of sub-partitions being connected to each other, and the other ends of each of the plurality of sub-partitions being spaced apart. A partition 340 may include a sub-partition and a first electromagnetic shielding layer 3122 covering the sub-partition.

[0161] In some examples, the inner partition 312 may be detachably connected to the support tube 311 .

[0162] For example, the partition frame 3121 can be elastic. When the partition frame 3121 is installed in the support tube 311, the partition frame 3121 can be compressed. At this time, the partition frame 3121 can generate a rebound force. Under the action of the rebound force, the partition frame 3121 can resist the inner wall of the support tube 311.

[0163] In other embodiments, the inner partition 312 includes a partition frame 3121, and the partition frame 3121 is made of an electromagnetic shielding material, so that the inner partition 312 has electromagnetic shielding properties. In this example, the first electromagnetic shielding layer 3122 may not be provided on the surface of the partition frame 3121.

[0164] For example, the separation frame 3121 can be made of a conductive material, such as a conductive adhesive material, or a metal material such as copper or silver. The material of the separation frame 3121 can be changed according to demand, and the material of the separation frame 3121 is not limited in the embodiment of the present application.

[0165] The partition frame 3121 is made of electromagnetic shielding material, which can simplify the structure of the inner partition 312 and facilitate the manufacture of the inner partition 312.

[0166] In some examples, the first signal module 300 may further include a second grounding terminal, which is electrically connected to the separation frame 3121 and is located at one end of the separation frame 3121. In this case, the second grounding terminal may be located at the first connection end 301 of the first signal module 300. The second grounding terminal may be used to connect to the first circuit board 400 (such as Figure 5 The grounding terminal on the partition frame 3121 is connected to the partition frame 3121, so that the partition frame 3121 can receive the grounding signal. The number of the second grounding terminals can be one or more, and the number of the second grounding terminals is not limited in the embodiment of the present application.

[0167] In the embodiment of the present application, the second grounding terminal may be only provided at the first connection end 301 of the first signal module 300 , that is, the first signal module 300 . Therefore, the number of second grounding terminals in the connector female head 200 may be reduced.

The tube body 3111 is made of an insulating material, and the second electromagnetic shielding layer 3112 is disposed on the inner surface 3113 and / or the outer surface 3114 of the tube body 3111. The second electromagnetic shielding layer 3112 is the electromagnetic shielding layer included in the support tube 311.

[0169] The inner surface 3113 of the tube body 3111 is located in the area surrounded by the outer surface 3114 of the tube body 3111 .

[0170] The tube body 3111 is covered with a second electromagnetic shielding layer 3112 , so that the support tube 311 has electromagnetic shielding properties.

[0171] The inner surface 3113 of the tube body 3111 is covered with a second electromagnetic shielding layer 3112 .

[0172] Alternatively, the outer surface 3114 of the tube body 3111 is covered with a second electromagnetic shielding layer 3112 .

[0173] Alternatively, the inner surface 3113 and the outer surface 3114 of the tube body 3111 are both covered with a second electromagnetic shielding layer 3112. The second electromagnetic shielding layer 3112 can cover the inner surface 3113 and the outer surface 3114 of the tube body 3111, thereby improving the electromagnetic shielding effect of the support tube 311, and further improving the electromagnetic shielding effect of the electromagnetic shielding cavity 330.

[0174] The second electromagnetic shielding layer 3112 may be formed on the inner surface 3113 or the outer surface 3114 of the tube body 3111 by electroplating or deposition process.

[0175] When the second electromagnetic shielding layer 3112 is located on the outer surface 3114 of the tube body 3111, the second electromagnetic shielding layer 3112 may be a metal film, and in this case, the metal film may be wrapped around the outer surface 3114 of the tube body 3111. In this case, the metal film is bonded to the outer surface 3114 of the tube body 3111.

[0176] For example, the tube body 3111 is made of insulating materials such as ceramics and plastics, wherein the material of the tube body 3111 can be changed accordingly according to needs, and the material of the tube body 3111 is not limited in the embodiment of the present application.

[0177] For example, the second electromagnetic shielding layer 3112 can be made of a conductive material, such as a conductive adhesive material, or a metal material such as copper or silver. The material of the second electromagnetic shielding layer 3112 can be changed as needed. In the embodiment of the present application, the material of the second electromagnetic shielding layer 3112 is not limited.

[0178] In some examples, the first signal module 300 may further include a third grounding terminal, which is electrically connected to the second electromagnetic shielding layer 3112 and is located at one end of the second electromagnetic shielding layer 3112. For example, the second electromagnetic shielding layer 3112 may be located at the first connection end 301 of the first signal module 300. The third grounding terminal may be used to connect with the grounding terminal on the first circuit board 400, so that the second electromagnetic shielding layer 3112 may receive a grounding signal. The number of the third grounding terminals may be one or more, and in the embodiment of the present application, the number of the third grounding terminals is not limited.

[0179] In the embodiment of the present application, the third grounding terminal may be only provided at the first connection end 301 of the first signal module 300 , and thus the number of the third grounding terminals in the female connector 200 may be reduced.

[0180] In other embodiments, the support tube 311 includes a tube body 3111, and the tube body 3111 is made of an electromagnetic shielding material, so that the support tube 311 has electromagnetic shielding properties. It can be understood that in this example, the second electromagnetic shielding layer 3112 may not be provided on the surface of the tube body 3111. The tube body 3111 is the electromagnetic shielding layer included in the support tube 311.

[0181] For example, the tube body 3111 can be made of a conductive material, such as a conductive adhesive material, or a metal material such as copper or silver. The material of the tube body 3111 can be changed according to demand. In the embodiment of the present application, the material of the tube body 3111 is not limited.

[0182] The tube body 3111 is made of electromagnetic shielding material, which can simplify the structure of the support tube 311.

[0183] In some examples, the first signal module 300 may further include a fourth grounding terminal, which is electrically connected to the tube body 3111 and located at one end of the tube body 3111. For example, the fourth grounding terminal may be located at the first connection end 301 of the first signal module 300. The fourth grounding terminal may be used to connect with the grounding terminal on the first circuit board 400, so that the tube body 3111 may receive a grounding signal. The number of the fourth grounding terminals may be one or more, and in the embodiment of the present application, the number of the fourth grounding terminals is not limited.

[0184] In the embodiment of the present application, the fourth grounding terminal may be only provided at the first connection end 301 of the first signal module 300 , and thus the number of the fourth grounding terminals in the female connector 200 may be reduced.
