Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of communication, and in particular, to a female connector, a connector assembly and an electronic device. BACKGROUND

[0002] In a communication device system, the interconnection system of the combination of the backplane based on the printed circuit board (PCB) and the board card is the most common interconnection architecture. As the connecting bridge between the backplane and the board card, the backplane connector is a key architecture level component. However, with the improvement of serial / deserial power, based on the consideration of thermal design, more and more electronic devices adopt the orthogonal architecture without backplane, and use the connector assembly to realize the mutual matching of the terminal interface of the male connector and the terminal interface of the female connector at 90° and 270° two angles, so as to realize the orthogonal architecture in the electronic device. However, the current connector still has problems such as low signal density and still cannot meet the needs of heat dissipation performance, which negatively affects the overall performance of the interconnection system.

[0003] Therefore, how to improve the signal density and heat dissipation performance of the connector is the key problem for the person skilled in the art to continue to study. SUMMARY

[0004] Embodiments of the present application provide a female connector, a connector assembly and an electronic device, and the main purpose is to improve the signal density and heat dissipation performance of the connector.

[0005] To achieve the above purpose, embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the present application provides a female connector, which includes a plurality of first sheet structures arranged in a first direction and a plurality of second sheet structures arranged in a second direction. The first direction intersects the second direction, and the heat dissipation directions of the first sheet structures and the second sheet structures are different, thereby improving the heat dissipation performance of the female connector. Each first sheet structure includes a plurality of signal lines, and the plurality of signal lines includes a plurality of first signal lines arranged in the same layer. The first sheet structure includes a first side surface facing the second direction and a second side surface facing a third direction, and the first side surface and the second side surface expose the end portions of the signal lines. The third direction intersects the first direction and the second direction, so that the planes in which the two exposed ends of the signal lines in the first sheet structure are located intersect, which can enable the two terminal interfaces of the male connector and the female connector to be mutually matched at a specific angle. The second sheet structure includes a third side surface facing away from the third direction and a fourth side surface facing the third direction. The third side surface has a plurality of first openings arranged in the first direction, and the first openings are used to accommodate the end portions of the signal lines exposed in the third direction. The fourth side surface has a plurality of second openings arranged in the first direction, and the second openings are used to be connected with the male connector.

[0007] The first aspect is provided by the female connector, on the one hand, the stacking direction of the plurality of first sheet structures and the stacking direction of the plurality of second sheet structures intersect, so that the two parts of the structure can conduct heat in different directions according to the direction of the sheet extension, improving the heat dissipation capacity of the first sheet structure and the second sheet structure, and then improving the heat dissipation performance of the female connector, which helps to improve the heat dissipation performance of the related equipment. On the other hand, by setting the end direction of the signal line in the first sheet structure, the two ends of the signal line exposed in the first sheet structure are located on the first side surface facing the second direction and the second side surface facing the third direction of the first sheet structure, respectively, and the second direction intersects with the third direction, so that the plane where the two ends of the signal line are located intersects, the first circuit board is connected with one end of the signal line in the female connector, and the second circuit board can be connected with the other end of the signal line in the female connector through the male connector. Thus, it can help to form a 90° or 270° orthogonal architecture between the first circuit board and the second circuit board. On the other hand, by using the plurality of signal lines arranged in the same layer in the first sheet structure, it can help to further improve the distribution density of the signal line, thereby improving the system rate of the female connector.

[0008] In combination with the first aspect, in a possible implementation, the first signal line is configured to transmit a first differential signal. Each first sheet structure further includes a plurality of second signal lines arranged in the same layer, and the second signal lines are configured to transmit a second differential signal. Wherein, along the first direction, the spacing between the first signal line and the second signal line is greater than zero. In this implementation, the first signal line and the second signal line are in different layers, realizing the transmission structure of the differential signal pair, which helps to further improve the distribution density of the signal line, thereby improving the system rate of the female connector, and taking into account the strong heat dissipation capacity.

[0009] In combination with the first aspect, in a possible implementation, the first signal line and the second signal line are opposite to each other along the first direction. Thus, not only the transmission structure of the differential signal pair is realized, but also the signal integrity impedance in the female connector can be adjusted through signal coupling.

[0010] With reference to the first aspect, in a possible implementation manner, each first sheet structure further includes a first insulating sheet and a second insulating sheet which are stacked along the first direction. The first insulating sheet is provided with a plurality of first grooves on a side facing away from the second insulating sheet, and the partial structure between the part of the first signal line exposed to the second direction and the part exposed to the third direction is located in the first grooves. The second insulating sheet is provided with a plurality of second grooves on a side facing away from the first insulating sheet, and the partial structure between the end of the second signal line exposed to the second direction and the end exposed to the third direction is located in the second grooves. By this implementation manner, the first signal line and the second signal line are respectively arranged in the grooves of different insulating sheets, which not only helps to guarantee the insulation performance of the signals, but also further improves the heat dissipation performance of the female connector by using the split arrangement of the insulating sheets.

[0011] With reference to the first aspect, in a possible implementation manner, each first sheet structure further includes two shielding sheets which are located on opposite sides of the plurality of signal lines along the first direction. The size of the orthographic projection of the plurality of first grooves and the plurality of second grooves on the shielding sheets is less than or equal to the size of the shielding sheets. In this implementation manner, the shielding sheets can be used to shield the signals of the first signal line and the second signal line, so that each first sheet structure can perform efficient and independent signal transmission work.

[0012] With reference to the first aspect, in a possible implementation manner, the width of the signal line is greater than the thickness thereof. In this way, the broad sides of the first signal line and the second signal line are opposite and coupled, thereby realizing the coupling of the broad sides of the signal lines, which helps to further adjust the signal integrity impedance in the female connector to be optimal.

[0013] With reference to the first aspect, in a possible implementation manner, the second sheet structure includes a metal frame which surrounds the openings and is used to shield the signals of the ends of the signal lines and the ends of the signal lines in the male connector, and the high thermal conductivity of the metal material can be used to further improve the heat dissipation capability of the female connector.

[0014] The second aspect, the embodiments of the present application provide a connector assembly, which includes a male connector and the female connector in any of the above embodiments, and the male connector is connected with the second opening in the female connector.

[0015] The third aspect, the embodiments of the present application provide an electronic device, which includes a printed circuit board and the female connector in any of the above embodiments, or includes a printed circuit board and the connector assembly in any of the above embodiments. At least one end of the signal line exposed to the third direction is connected with the printed circuit board.

[0016] With reference to the third aspect, in a possible implementation, each first sheet structure further includes two shielding sheets, which are located on opposite sides of the plurality of signal lines along the first direction. The female connector is connected to the printed circuit board by means of fish-eye crimping or elastic sheet crimping through the side structure of the shielding sheets facing the second direction. In this way, not only can the first signal lines and the second signal lines be shielded, but also the female connector and the printed circuit board can be connected by means of the shielding sheets.

[0017] The technical effects brought by any one of the second aspect and the third aspect can be referred to the technical effects brought by different design manners of the first aspect, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0034] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments provided by the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0035] In the description of the embodiments of the present application, "a plurality of" means two or more than two, unless otherwise specified. "At least one" or similar expressions mean any combination of the items, including any combination of single item or multiple items. For example, at least one of a, b and c can represent a, b, c, a-b, a-c, b-c or a-b-c, where a, b and c can be single or multiple. "A and / or b" includes the following three combinations: only a, only b, and a combination of a and b.

[0036] In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second" and the like are used to distinguish the same items or similar items with basically the same function and effect. A person skilled in the art can understand that "first", "second" and the like do not limit the quantity and execution order, and "first", "second" and the like do not necessarily mean different. At the same time, in the embodiments of the present application, "exemplary" or "for example" means to serve as an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, "exemplary" or "for example" is used to present the relevant concept in a specific manner, for understanding.

[0037] In describing some embodiments, the use of "connection" and / or "connected" is used. It is to be understood that the term "connection" is to be taken in a broad sense and can be, for example, an electrical connection formed based on a conductor. Of course, "connection" can also be a fixed connection, or a detachable connection, or integral; it can be directly connected, or indirectly connected through an intermediate medium. In addition, the use of "based on" means open and inclusive, because the process, step, calculation or other action "based on" one or more stated conditions or values can be based on additional conditions or values beyond those stated in practice.

[0038] As used herein, "parallel," "perpendicular," "equal" include the stated condition and conditions that approximate the stated condition within an acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art taking into account the measurement being discussed and the error associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, "parallel" includes absolute parallel and near parallel, where the acceptable deviation range for near parallel can be, for example, within 5°; "perpendicular" includes absolute perpendicular and near perpendicular, where the acceptable deviation range for near perpendicular can also be, for example, within 5°. "Equal" includes absolute equality and near equality, where the acceptable deviation range for near equality can be, for example, a difference between the two that is less than or equal to 5% of either.

[0039] In the embodiments of the present application, "upper", "lower", "left", "right" are not limited to the relative positions of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and which can change accordingly according to the change of the position of the components shown in the drawings. In the drawings, the thicknesses of the layers and regions are exaggerated for clarity, and the dimensional proportions among the parts shown in the drawings do not reflect actual dimensional proportions. Therefore, variations in the shapes of the components with respect to the drawings can be contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, the exemplary embodiments should not be construed as limited to the shapes of the regions shown in the drawings, but include deviations in shapes due to, for example, manufacturing. For example, etched regions that are shown as rectangular will typically have curved features. Therefore, the regions shown in the drawings are schematic and not intended to indicate the actual shape of the region of a device and are not intended to limit the scope of the exemplary embodiments.

[0040] In addition, the architecture and scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, as the architecture evolves and new scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0041] Embodiments of the present application provide an electronic device which can be applied to various communication systems or communication protocols, such as global system of mobile communication (GSM), code division multiple access (CDMA) system, wideband code division multiple access wireless (WCDMA), general packet radio service (GPRS), long term evolution (LTE), and the like.

[0042] The electronic device described above may, for example, include a consumer product, a home product, a vehicle-mounted product, a wearable product, a financial terminal product, a communication product, a smart detection product. Illustratively, the electronic device may, but is not limited to, be a computing device in a supercomputer cluster, a communication device in a supercomputer cluster, a switch, a headset, a microphone, a mobile phone, a pad, a smart wearable product (e.g., a smart watch, a smart bracelet), an extended reality (XR) device, an inertial navigation device, a supplemental inflatable restraint system (SRS) device of an automobile, a smart door lock, a stethoscope, a helmet, a handle, a fluid manometer, and the like. The XR device described above may, for example, be a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device. Embodiments of the present application do not specially limit the specific form of the device described above.

[0043] Electronic devices often need to use printed circuit boards for the connection, integration and signal transmission of electronic components, and multiple printed circuit boards can be connected through a connector assembly. Embodiments of the present application propose some schemes to realize the orthogonal architecture without backboard between printed circuit boards by using the connector assembly, which can improve the heat dissipation performance of internal components of the electronic device to a certain extent. For example, Figure 1The electronic device 1000 shown can use the connector assembly 100a to make the terminal interface of the male connector 1a and the terminal interface of the female connector 2a realize two angles of 90° and 270°, and the terminal interface of the male connector 1a is connected with the first mainboard 200a, and the terminal interface of the female connector 2a is connected with the second mainboard 300a, so as to realize the orthogonal architecture that the first mainboard 200a and the second mainboard 300a are perpendicular to each other in the electronic device 1000.

[0044] In some technologies, please refer to Figure 2 , a male connector 1a is proposed, which includes a connecting sheet 11a and a shielding sheet 12a, and the connecting sheet 11a is provided with a signal line 111a. As shown in Figure 2 , one end of the signal line 111a forms a signal pin, and the signal pin is bent by 90° to be connected with a ground pin 121a included in the shielding sheet 12a, so as to form a bidirectional matching no-middle-board orthogonal connector. However, this scheme cannot realize a differential pair structure due to the use of a single-end signal line, the system rate is low, and the cylindrical structure used in the connector in this scheme is not conducive to improving the layout density of the signal line, and further limits the improvement of the connection performance.

[0045] In some other technologies, please refer to Figure 3 , a connector assembly 100a is proposed, which proposes another terminal bending scheme, wherein the signal line in the connector assembly 100a includes a signal terminal pair 110a as shown in Figure 4 , which includes a first signal terminal 1101a and a second signal terminal 1102a to realize the transmission of differential signals and improve the connection performance of the connector assembly 100a to a certain extent. However, the heat dissipation performance of this scheme still cannot meet the needs, and the connection performance also needs to be further improved.

[0046] In some other technologies, a connector assembly is proposed, please refer to Figure 5 , which includes a lead frame assembly 13a, and the lead frame assembly 13a is bent by the sheet structure itself, so that the signal line 131a is bent by 90°, so as to realize the orthogonal architecture of the connector. However, this connector assembly not only greatly increases the process difficulty, but also easily causes heat accumulation in the bending area, and the heat dissipation performance still needs to be further improved.

[0047] Based on this, the embodiment of the present application also provides a connector assembly for improving the signal density and heat dissipation performance of the connector.

[0048] Please refer to Figure 6AThe connector assembly 100 comprises the male connector 1 and the female connector 2, wherein the male connector 1 is connected with the female connector 2.

[0049] The present application also provides a female connector, please refer to Figure 7 The female connector 2 can comprise a plurality of first sheet structures 21 arranged in a first direction X and a plurality of second sheet structures 22 arranged in a second direction Y.

[0050] In some optional embodiments, the two adjacent first sheet structures 21 can have a gap or be closely connected. The present application does not limit this.

[0051] In some optional embodiments, the two adjacent second sheet structures 22 can have a gap or be closely connected. The present application does not limit this.

[0052] Please refer to Figure 8 The first direction X and the second direction Y intersect, the first sheet structure 21 and the second sheet structure 22 dissipate heat along the sheet plane, and the first sheet structure 21 and the second sheet structure 22 are stacked in different directions, so the heat dissipation directions are different, so as to improve the heat dissipation performance of the female connector 2.

[0053] In some examples, the first direction X and the second direction Y can be perpendicular to each other, so as to realize the orthogonal architecture, thereby further improving the heat dissipation performance of the female connector 2 and the connector assembly or electronic equipment to which the female connector 2 is applied.

[0054] Please refer to Figure 9A In the present application, each first sheet structure 21 comprises a plurality of signal lines 211, and the plurality of signal lines comprises a plurality of first signal lines 211a arranged in the same layer. For example, please refer to Figure 9A The first signal lines 211a arranged in the same layer can be located in the plane formed by the second direction Y and the third direction Z.

[0055] Please refer to Figure 9AIn some optional embodiments, each signal line 211 can include a first section 2111, a second section 2112, and a third section 2113. The first section 2111 can extend along the third direction Z, the second section 2112 can extend along the fourth direction W, and the third section 2113 can extend along the second direction Y. The third direction Z can intersect the second direction Y, and the fourth direction W can intersect the second direction Y and the third direction Z, respectively. Thus, the planes in which the terminal interfaces at the two ends of the signal line are located can intersect each other, facilitating the connection of the orthogonal architecture. Further, in some examples, the third direction Z can be perpendicular to the second direction Y. Thus, the planes in which the terminal interfaces at the two ends of the signal line are located can be perpendicular to each other, allowing the female connector 2 to be used as a bent female connector and applied to a connector assembly or an electronic device to form a connection of the orthogonal architecture.

[0056] Please refer to Figure 8 The first sheet structure 21 includes a first side surface 212 facing the second direction Y and a second side surface 213 facing the third direction Z, and the first side surface 212 and the second side surface 213 expose the end portions of the signal lines 211. Figure 8 The end portions of the signal lines 211 exposed by the first side surface 212 are shown. The third direction Z intersects the first direction X and the second direction Y, and thus the planes in which the two ends of the signal lines 211 in the first sheet structure 21 are located intersect each other, allowing the male connector and the female connector 2 to be mated at a specific angle.

[0057] The end portions of the signal lines 211 exposed toward the third direction Z can be used to electrically connect with the first circuit board 310. Accordingly, the second side surface 213 of the first sheet structure 21 facing the third direction Z can serve as a packaging surface, and the first side surface 212 of the first sheet structure 21 facing the second direction Y can serve as a mating surface.

[0058] In some optional embodiments, the male connector can be connected with the second circuit board, and the female connector can be connected with the first circuit board. The terminal interface of the male connector can be the plane in which the second circuit board connected with the male connector is located, and the terminal interface of the female connector can be the plane in which the first circuit board connected with the female connector is located.

[0059] In some optional embodiments, the male connector can be connected with the second circuit board, and the female connector can be connected with the first circuit board. The terminal interface of the male connector can be the plane in which the second circuit board connected with the male connector is located, and the terminal interface of the female connector can be the plane in which the first circuit board connected with the female connector is located.

[0060] Please refer to Figure 8The second sheet-like structure 22 includes a third side 221 facing away from the third direction Z and a fourth side 222 facing the third direction Z. Please refer to [reference needed]. Figure 10A The third side surface 221 has a plurality of first openings 223 arranged along the first direction X, the first openings 223 being used to accommodate Figure 8 The end of signal line 211 exposed in the Z-direction. Please refer to... Figure 10B The fourth side 222 has a plurality of second openings 224 arranged along the first direction X, the second openings 224 being used for mating with a male connector.

[0061] In this embodiment of the application, the opening in the female connector 2 for mating with the male connector can be oriented toward the male connector. Specifically, the opening in the female connector 2 for mating with the male connector can be a second opening 224.

[0062] Through the above embodiments, such as Figure 7 The stacking directions of the plurality of first sheet-like structures 21 and the stacking directions of the plurality of second sheet-like structures 22 in the female connector 2 shown intersect, allowing the two structures to conduct heat in different directions according to the direction of sheet extension. This improves the heat dissipation capacity of the first sheet-like structures 21 and the second sheet-like structures 22, thereby improving the heat dissipation performance of the female connector 2 and thus contributing to the improvement of the heat dissipation performance of related equipment (such as connector assemblies or electronic devices). Furthermore, through methods such as... Figure 8 The arrangement of the end directions of the signal lines 211 in the first sheet structure 21 shown is such that the exposed ends of the signal lines 211 are located on two sides of the first sheet structure 21 facing different directions, and the planes containing the two ends of the signal lines 211 intersect. The first circuit board can be connected to one end of the signal line 211, and the second circuit board can be connected to the other end of the signal line through a male connector. This helps to form an orthogonal structure of 90° or 270° between the first circuit board and the second circuit board. Furthermore, by using multiple signal lines 211 arranged in the same layer in the first sheet structure 21, the distribution density of the signal lines 211 can be further increased, thereby improving the system speed of the female connector 2.

[0063] Please refer to Figure 10A In conjunction with the above embodiments, in some optional implementations, the first opening 223 and Figure 10B The second opening 224 shown is interconnected.

[0064] Please refer to Figure 10A and Figure 10B In conjunction with the above embodiments, in some optional implementations, the second sheet structure 22 includes a metal frame surrounding each opening. Exemplarily, the metal frame may form a 360-degree frame structure around each opening.

[0065] The metal frame can signal shield the end of the signal line and the end of the signal line in the male connector, improve the functional stability of the connector, and also use the high thermal conductivity of the metal material to improve the heat conduction ability of the second sheet structure 22, thereby further improving Figure 7 the heat dissipation ability of the female connector 2 and related devices (such as connector assemblies and electronic devices) shown.

[0066] Further, in some optional embodiments, please refer to Figures 10A-10C , Figure 10C The female connector 2 shown can also include an insulating material 225, which can coat the inner wall surface and / or the outer wall surface of the metal frame in the second sheet structure 22. Figure 10A or Figure 10B Thereby, not only the surface insulation of the metal frame can be realized, but also the overall packaging of the multiple second sheet structures 22 can be realized, thereby ensuring the functional stability of the connector, and the state presented on the product can refer to Figure 6B .

[0067] Please refer to Figure 9B , in some optional embodiments, the structure type of the end of the signal line 211 exposed to the third direction Z can include a clamping terminal structure, so that the male connector is connected with the clamping terminal structure through the second opening 224 (refer to Figure 10B ) located at the fourth side surface of the second sheet structure 22. Exemplarily, the structure type of the end of the signal line 211 exposed to the third direction Z can include a round clamping terminal structure.

[0068] Please refer to Figure 11 , in combination with the above embodiments, in some optional embodiments, the first signal line 211a is configured to transmit a first differential signal. Each first sheet structure 21 further includes multiple second signal lines 211b arranged in the same layer, and the second signal lines 211b are configured to transmit a second differential signal.

[0069] In some examples, the first differential signal can be a positive polarity (Positive, P) signal, and the second differential signal can be a negative polarity (Negative, N) signal.

[0070] In yet other examples, the first differential signal can be a negative polarity (Negative, N) signal, and the second differential signal can be a positive polarity (Positive, P) signal.

[0071] Specifically, the first signal line 211a and the second signal line 211b can be differential signal lines, form a differential signal line group, and the differential signal line group can be used to transmit a differential signal pair composed of a first differential signal and a second differential signal, thereby realizing transmission of differential signals, improving the system rate of the connector, and then improving the connection performance. For example, the female connector or the connector assembly to which the female connector is applied can support a system rate of up to 112G or 224G.

[0072] Referring to Figure 12 , the pitch of the first signal line 211a and the second signal line 211b along the first direction X is greater than zero, so as to realize the separation of signals. In the implementation mode, the first signal line 211a and the second signal line 211b are in different layers, realize the transmission structure of the differential signal pair, help to further improve the distribution density of the signal line, and then improve the system rate of the female connector, and take into account the strong heat dissipation capacity.

[0073] Referring to Figure 12 , in combination with the above embodiment, in some optional implementation modes, the first signal line 211a and the second signal line 211b are opposite to each other in pairs along the first direction X.

[0074] Specifically, in some optional implementation modes, the orthographic projection of the first signal line 211a on the second signal line 211b can overlap the first signal line 211a, or the orthographic projection of the second signal line 211b on the first signal line 211a can overlap the second signal line 211b.

[0075] For example, the acceptable deviation range of "overlap" can be that the distance between the two contours is less than or equal to 5% of the length or width of the signal line in the direction where the distance is located.

[0076] Through the above embodiment, not only the transmission structure of the differential signal pair is realized, but also the signal integrity impedance in the female connector can be adjusted through signal coupling, and then the connection performance of the connector is improved.

[0077] Referring to Figure 11 , in combination with the above embodiment, in some optional implementation modes, the width of the signal line 211 is greater than the thickness of the signal line 211.

[0078] For example, the width of the signal line 211 can be the line width dimension of the signal line 211 in the plane where the second direction Y and the third direction Z are located, and the thickness of the signal line 211 can be the dimension along the stacking direction (the first direction X) of the first sheet structure 21.

[0079] Thus, the wide side of the first signal line 211a can be opposite to and coupled with the wide side of the second signal line 211b, so as to realize the coupling of the wide sides of the signal lines 211, and help to further adjust the signal integrity impedance in the female connector to an optimal value, so as to improve the connection performance of the connector.

[0080] Please refer to Figure 11 In some optional embodiments, each first sheet structure 21 further comprises a first insulating sheet 214 and a second insulating sheet 215 which are stacked along the first direction X. The first insulating sheet 214 is provided with a plurality of first grooves 2141 on the side facing away from the second insulating sheet 215, and the partial structure between the part of the first signal line 211a exposed to the second direction Y and the part exposed to the third direction Z is located in the first grooves 2141.

[0081] In some optional embodiments, the width of the first grooves 2141 is equal to or slightly greater than the width of the first signal line 211a, and the depth of the first grooves 2141 is equal to or slightly greater than the thickness of the first signal line 211a, so as to embed the first signal line 211a in the first grooves 2141.

[0082] In some examples of the present application, the value A is "slightly greater than" the value B, which means that the value A is greater than the value B and does not exceed 10%.

[0083] Please refer to Figure 11 The second insulating sheet 215 is provided with a plurality of second grooves (not shown in the figure, the structure of which can refer to the first grooves 2141 in Figure 11 The second signal line 211b is provided with a plurality of second grooves (not shown in the figure, the structure of which can refer to the first grooves 2141 in

[0085] Please refer to Figure 11 In some optional embodiments, in the same first sheet structure 21, the first insulating sheet 214 and the second insulating sheet 215 can have a gap therebetween or can be closely connected. The embodiments of the present application do not limit this.

[0086] Through the above embodiment, the first signal line 211a and the second signal line 211b are respectively arranged in the channels of different insulating sheets, which not only helps to guarantee the insulation performance of the signals, but also further improves the heat dissipation performance of the female connector by using the split arrangement of the insulating sheets.

[0087] In some optional embodiments, the first insulating sheet 214 or the second insulating sheet 215 can also be provided with a wire hole extending along the plane where it is located, and the structure between the part of the signal line 211 exposed to the second direction Y and the part exposed to the third direction Z can also be buried in the wire hole to protect the structure and electrical function of the signal line 211.

[0088] In some optional embodiments, the first insulating sheet 214 can also be provided with the first channel 2141 and the wire hole at the same time, and the structure between the part of the first signal line 211a exposed to the second direction Y and the part exposed to the third direction Z can be located in the first channel 2141, and another structure between the part of the first signal line 211a exposed to the second direction Y and the part exposed to the third direction Z is buried in the wire hole, which not only facilitates the manufacture of the first signal line 211a, but also protects the structure and electrical function of the first signal line 211a.

[0089] Alternatively, the second insulating sheet 215 can also be provided with the second channel and the wire hole at the same time, and the structure between the part of the second signal line 211b exposed to the second direction Y and the part exposed to the third direction Z can be located in the second channel, and another structure between the part of the second signal line 211b exposed to the second direction Y and the part exposed to the third direction Z is buried in the wire hole, which not only facilitates the manufacture of the second signal line 211b, but also protects the structure and electrical function of the second signal line 211b.

[0090] Please refer to Figure 11 , in combination with the above embodiment, in some optional embodiments, each first sheet structure 21 further includes two shielding sheets 216, which are located on opposite sides of the plurality of signal lines 211 along the first direction X.

[0091] Through the above embodiment, the first signal line 211a and the second signal line 211b can be shielded by the shielding sheet 216 respectively, so that each first sheet structure 21 can perform efficient and independent signal transmission work.

[0092] Among them, the size of the orthographic projection of the plurality of first channels 2141 and the plurality of second channels on the shielding sheet is less than or equal to the size of the shielding sheet, so as to achieve sufficient shielding of the signal lines 211 located in the first channel 2141 and the second channel.

[0093] In some optional embodiments, the shielding sheet can be provided in a hollow shape according to the shape of the first channel or the second channel, so as to save materials.

[0096] Please refer to Figure 11 In some optional embodiments, the size of the shielding sheet 216 in the orthographic projection pattern of the first insulating sheet 214 can be smaller than the size of the first insulating sheet 214, which can further facilitate the assembly of the first insulating sheet 214 and the shielding sheet 216. The size of the shielding sheet 216 in the orthographic projection pattern of the second insulating sheet 215 can be smaller than the size of the second insulating sheet 215, which can further facilitate the assembly of the second insulating sheet 215 and the shielding sheet 216.

In combination with the above embodiments, it can be seen that the depth of the signal hole 303 can guarantee a certain connection bandwidth when the depth is less than or equal to 4 microns. Therefore, in some optional embodiments, the depth of the signal hole 303 can be set to be less than or equal to 4 microns to guarantee the effect of signal connection, for example, to guarantee a connection bandwidth of 70Ghz.
