Description

Technical Field

[0001] The present application relates to the technical field of signal connection, and in particular to a connector and a network device. Background Art

[0002] For high-speed electrical signals, high-speed connectors are required for transmission. The main function of high-speed connectors is to connect devices and transmit data. The transmission rate is very fast and they are usually used in computers, communication equipment, industrial automation and medical equipment.

[0003] The crosstalk performance of high-speed connectors has an important impact on the transmission performance of high-speed links. In addition, for pluggable high-speed connectors, the signal return flow on the mating surfaces of the male and female ends of the high-speed connector is one of the main sources of crosstalk in the entire high-speed link. The female end of the existing pluggable high-speed connector is provided with a shielding structure, which can isolate the transmission signals of the male and female ends from the outside and reduce the crosstalk problem. However, after the female end and the male end are mated, there is still a signal return disorder problem on the mating surfaces of the two, resulting in insertion loss resonance, which affects the signal transmission integrity and plug-in reliability. Summary of the invention

[0004] The embodiments of the present application provide a connector and a network device, which reduce signal backflow disturbance and insertion loss resonance on the mating surfaces of the connectors, thereby improving signal transmission integrity and plug-in reliability.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a connector. The connector includes a plug assembly and a socket assembly, and the plug assembly and the socket assembly can be detachably connected, such as plugged in. Among them, the plug assembly includes a plug body, a plurality of first signal terminals and a plurality of grounding members. The plurality of first signal terminals are arranged on the plug body at intervals. For example, when the number of first signal terminals is small, the plurality of first signal terminals can be distributed in a row. When the number of first signal terminals is large, the plurality of first signal terminals can be distributed in an array. The plurality of grounding members are respectively located on the outside of the plurality of first signal terminals and connected to the plug body. The number of the plurality of grounding members can correspond to the number of the first signal terminals. Correspondence means that if the signal transmitted by the first signal terminal is a differential signal, and a pair of first signal terminals transmits a differential signal, the number of pairs of differential signal pairs composed of the plurality of first signal terminals is the same as the number of grounding members. The socket assembly includes a socket body, a plurality of second signal terminals and a shielding structure. The plurality of second signal terminals are arranged on the socket body at intervals, and the plurality of second signal terminals correspond to the plurality of first signal terminals respectively. Therefore, the plurality of first signal terminals can be distributed in a row or in an array. The plurality of second signal terminals can be connected to the plurality of first signal terminals in the plug assembly respectively. The shielding structure is arranged on the socket body and is arranged around the outer periphery of the plurality of second signal terminals. The shielding structure can be connected to the plurality of grounding members. The shielding structure is provided with a plurality of notches, and the plurality of notches can be arranged respectively opposite to the plurality of grounding members of the plug assembly. That is, the projection of any grounding member on the shielding structure is located at the corresponding notch. When the plug assembly is connected to the socket assembly, the plurality of grounding members are respectively located at the plurality of notches. When the plurality of grounding members are connected to the shielding structure, a plurality of shielding cavities can be formed around the plurality of second signal terminals and the plurality of first signal terminals. The plurality of shielding cavities can effectively protect the signals transmitted by the connector.

[0007] Therefore, the connector of the embodiment of the present application can form a closed shielding cavity around the periphery of the multiple second signal terminals and the multiple first signal terminals, and the grounding member can be accommodated in the notch of the shielding structure and block the multiple notches, thereby reducing the area of ​​the overlapping region between the grounding member and the shielding structure. Thus, the problems of reflux turbulence and insertion loss resonance caused by the small interval between the overlapping region of the grounding member and the shielding structure (i.e., the shielding gap) are avoided, and the bandwidth performance of the connector is improved. For example, the insertion loss resonance caused by the shielding gap within the frequency of 30-40GHz is avoided, so that the bandwidth is optimized to 38GHz. Furthermore, the signal transmission integrity and plug-in reliability of the connector are improved.

[0008] On this basis, in some embodiments of the present application, the side wall of the notch is provided with an elastic arm, and the elastic arm is used to elastically abut against the grounding member. When the socket assembly and the plug assembly are plugged in, the elastic arm will be squeezed and deformed by the grounding member. The restoring force of the elastic arm will cause the elastic arm to be pressed against the grounding member, and the connection force is reliable. Thus, the grounding member and the elastic arm are reliably connected, and the shielding reliability of the shielding structure is improved.

[0009] Furthermore, for grounding members of different shapes, different numbers of elastic arms may be used. In some embodiments, the side wall of the notch may be provided with only one elastic arm to abut against the corresponding grounding member. In other embodiments, the notch may be provided with multiple elastic arms to abut against the corresponding grounding member.

[0010] Among them, the projection of the above-mentioned grounding member on the shielding structure can completely overlap with the corresponding notch, or can only partially overlap. However, for the solution in which the projection of the grounding member on the shielding structure can partially overlap with the corresponding notch, when the plug assembly and the socket assembly are connected, the grounding member cannot completely block the notch, and there is a shielding loophole. Therefore, in some embodiments of the present application, the projection of the grounding member on the shielding structure partially overlaps with the corresponding notch. And, the above-mentioned elastic arm can block the gap between the notch and the grounding member. Thereby solving the above-mentioned problem. It can be understood that for the implementation method in which the projection of the grounding member on the shielding structure can completely overlap with the corresponding notch, the elastic arm can be used only to increase the connection strength between the grounding member and the second shielding plate at the notch.

[0011] In a specific embodiment, the grounding member is U-shaped, and the notch is a shape that is compatible with the U-shaped grounding member, such as a rectangular notch or a notch that is approximately rectangular. For the U-shaped grounding member, in some embodiments, two elastic arms are provided at the notch, and the two elastic arms are respectively against the two side plates at the opening of the U-shaped grounding member.

[0012] There are various implementation schemes for the above-mentioned shielding structure. In some embodiments of the present application, the above-mentioned shielding structure includes a first shielding plate, a second shielding plate and a plurality of shielding baffles, and the first shielding plate, the second shielding plate and the plurality of shielding baffles are all connected to the above-mentioned socket body. The first shielding plate and the second shielding plate are respectively located on two opposite sides of the plurality of second signal terminals. The plurality of shielding baffles are all located between the first shielding plate and the second shielding plate. Each shielding baffle is connected to the first shielding plate and the second shielding plate. Part of the shielding baffle is arranged between two adjacent second signal terminals, and the remaining part of the shielding baffle is arranged on the side close to the outside of the second signal terminal located at the edge position. The above-mentioned notch can be opened on the first shielding plate. Alternatively, the above-mentioned notch can also be opened on the second shielding plate. Alternatively, the above-mentioned notch is opened on the first shielding plate and the second shielding plate. In the shielding structure, the first shielding plate and the second shielding plate can be simultaneously arranged outside the plurality of second signal terminals, which reduces the number of parts and makes assembly more convenient.

[0013] Based on this, in some embodiments of the present application, the shielding partition includes an intermediate shielding partition and an end shielding partition. Among them, the intermediate shielding partition is located between two adjacent second signal terminals. The end shielding partition is arranged on the side of the second signal terminal located at the edge position close to the outside. The above-mentioned intermediate shielding partition includes a first shielding partition, a second shielding partition and a third shielding partition. The first shielding partition, the second shielding partition and the third shielding partition are connected and arranged in parallel. The first shielding partition is provided with a first elastic claw, and the second shielding partition is provided with a second elastic claw. The first elastic claw and the second elastic claw are bent in directions away from each other. The first elastic claw is used to abut against the corresponding grounding member. The second elastic claw is used to abut against the corresponding grounding member. The third shielding partition is located between the first shielding partition and the second shielding partition. The third shielding partition does not have other structures, that is, the third shielding partition is a partition without openings. Therefore, the middle shielding partition can not only abut against the two adjacent grounding parts, but also improve the sealing of the two shielding cavities where the first shielding partition and the second shielding partition are located through the third shielding partition, so that the signal isolation effect is good, the crosstalk resonance at the frequency of 30GHz is optimized, and the crosstalk noise at the frequency of 29.5GHz can be optimized by a maximum of 10dB.

[0014] Moreover, the components in the above-mentioned intermediate shielding partition can be connected in various ways. In some embodiments, the above-mentioned first shielding partition and the second shielding partition are an integrated structure, such as using a metal plate to form the first shielding partition and the second shielding partition by bending. The third shielding partition can be snapped with the first shielding partition and the second shielding partition. If a first snap-in protrusion is provided on the third shielding partition, a first snap-in hole matching the first snap-in protrusion is provided at the bending part of the above-mentioned metal plate. The first snap-in protrusion can be snapped into the first snap-in hole. The assembly of the components in the intermediate shielding partition is convenient, and the manufacturing process is also simple.

[0015] Based on the structure of the above-mentioned intermediate shielding baffle, in some embodiments, the above-mentioned socket body, the first shielding plate, and the second shielding plate are all provided with a second clamping hole, and the third shielding baffle may also be provided with a plurality of second clamping protrusions, and the plurality of second clamping protrusions respectively correspond to the positions of the above-mentioned second clamping holes. The plurality of second clamping protrusions may be respectively clamped with the second clamping hole on the socket body, the second clamping hole on the first shielding plate, and the second clamping hole on the second shielding plate. It is understandable that the above-mentioned plurality of second clamping protrusions may also be provided on the first shielding baffle. Or, the above-mentioned plurality of second clamping protrusions may also be provided on the second shielding baffle. Alternatively, the above-mentioned plurality of second clamping protrusions may be respectively provided on the first shielding baffle and the second shielding baffle. It is convenient to assemble the intermediate shielding baffle with the socket body, the first shielding plate, and the second shielding plate.

[0016] In some other embodiments of the present application, the first shielding baffle, the second shielding baffle and the third shielding baffle are an integrated structure. For example, the first shielding baffle, the second shielding baffle and the third shielding baffle are formed by bending the same metal plate. The intermediate shielding baffle can be S-shaped. The intermediate shielding baffle does not need to be assembled, which reduces the assembly operation of the connector. Based on the structure of the intermediate shielding baffle, in some examples, a plurality of third snap-in protrusions are provided on the first shielding baffle and the second shielding baffle. The socket body, the first shielding plate and the second shielding plate are all provided with third snap-in holes corresponding to the plurality of third snap-in protrusions. The plurality of third snap-in protrusions can be snap-in with the third snap-in hole of the socket body, the third snap-in hole of the first shielding plate and the third snap-in hole of the second shielding plate, respectively.

[0017] In the second aspect, an embodiment of the present application also includes a network device, which includes a first circuit board, a second circuit board and the connector described in the above embodiment. The plug assembly of the connector is arranged on the first circuit board. The socket assembly of the connector is arranged on the second circuit board. The plug assembly of the connector is plugged into the socket assembly to connect the first circuit board with the second circuit board. The first circuit board can specifically be a backplane. The second circuit board can be various business boards, such as a management board (the management board refers to a main board used for remote management and fault diagnosis of electronic equipment), a switching board, a control board or an interface board. Since the connector in the network device of the embodiment of the present application has the same structure as the connector described in the above embodiment, both can solve the same technical problems and obtain the same technical effects.

DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0042] In addition, in the present application, directional terms such as "up", "down", "left", "right", "horizontal" and "vertical" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0043] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can refer to the connection of mechanical structure or physical structure. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be directly connected or indirectly connected through an intermediate medium. It can also be understood as the physical contact and electrical conduction of components, and it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as PCB copper foil or wires that can transmit electrical signals.

[0044] The embodiment of the present application provides a network device, which may be a router, a switch, etc. For example, the router may be a core router or a convergence router. The switch may be a rack-mounted switch or a transmission switch. The embodiment of the present application does not impose any special restrictions on the specific form of the above network device. Figure 1 The network device shown is a router for example.

[0045] Reference Figure 1 , the router 1000 includes a backplane 100, a control board 200 and an interface board 300. The control board 200 and the interface board 300 are both mounted on the backplane 100. The control board 200 is used to perform routing calculations, maintain routing tables, transmit routing information, etc. The interface board 300 performs forwarding processing of message input or output. In some examples, the interface board 300 may have routing table cache (cache) and other complex problem processing capabilities. The backplane 100 is responsible for forwarding messages between the control board 200 and the interface board 300. The control board 200, the backplane 100 and the interface board 300 can all be circuit boards.

[0046] To achieve signal transmission between the backplane 100 and the control board 200 and the interface board 300, the router 1000 includes a plurality of Figure 2 The connector 400 shown includes a plug assembly 10 (i.e., a male connector) and a socket assembly 20 (i.e., a female connector). Taking the connection between the backplane 100 and the interface board 300 as an example, the plug assembly 10 can be connected to the backplane 100, and the socket assembly 20 can be connected to the interface board 300. After the plug assembly 10 and the socket assembly 20 are plugged in, the backplane 100 can perform data transmission with the interface board 300. The plugging surface of the plug assembly 10 and the socket assembly 20 in the connector 400 is the mating surface. Since the signal backflow on the mating surface will seriously affect the high-speed data transmission quality of the router 1000, it is necessary to try to avoid the problem of signal backflow on the mating surface.

[0047] To this end, the embodiment of the present application improves the structure of the connector 400. The structure of a specific embodiment of the connector 400 of the present application is described in detail below.

[0048] In some examples of this application, reference Figure 3 and Figure 4 , the above-mentioned plug assembly 10 includes a plug body 1a, multiple connectors 2a, multiple data lines 3a, a connecting plate 4a and a fixing part 5a. Among them, the plug body 1a may include a supporting structure made of insulating materials such as plastic. Each connector 2a includes a first signal terminal 21a and a grounding part 22a, and the first signal terminal 21a is used to transmit signal data. The first signal terminal 21a can specifically adopt a connecting plate structure. The grounding part 22a is used for grounding. In some examples, multiple first signal terminals 21a in multiple connectors 2a can constitute multiple pairs of first differential signal pairs 210a. Thereby, the plug assembly 10 can transmit multiple differential signals simultaneously. As Figure 5 As shown, each pair of first differential signal pairs 210a includes two first signal terminals 21a, and the two first signal terminals 21a are adjacent. One end of the two first signal terminals 21a is installed in the plug body 1a, and the other end of the two first signal terminals 21a is located outside the plug body 1a. For example, the grounding member 22a includes two grounding portions 221a and a connecting portion 222a, and the two grounding portions 221a are respectively located on both sides of the first differential signal pair 210a, and the connecting portion 222a connects the two grounding portions 221a. A part of the two grounding portions 221a and the connecting portion 222a in the grounding member 22a are installed in the plug body 1a. Another part of the two grounding portions 221a and the connecting portion 222a in the grounding member 22a is located outside the plug body 1a and surrounded by the outside of the first differential signal pair 210a. One end of the plurality of data lines 3a is also installed in the plug body 1a, and is connected and conductive with the plurality of first signal terminals 21a and the plurality of grounding members 22a. Therefore, the number of the multiple data lines 3a is the same as the number of the multiple first signal terminals 21a. The other ends of the multiple data lines 3a are passed through the outside of the plug body 1a and are used to connect to other external devices. For example, the multiple data lines 3a are connected to an optical module or a plug. It can be understood that for the socket assembly 20 that needs to be plugged into the circuit board, the data line 3a can also be replaced by a data pin. A plurality of fixing holes 41a are provided on the connecting plate 4a, and a plurality of connectors 2a can be respectively installed in the plurality of fixing holes 41a. The connecting plate 4a is connected to the socket body 1b, and the plurality of connectors 2a can be separated and fixed. The fixing member 5a is also connected to the socket body 1b.

[0049] In some examples, such as Figure 3 As shown, the multiple connectors 2a and the multiple data lines 3a are distributed in an array. When the number of the multiple connectors 2a and the multiple data lines 3a is small, the multiple connectors 2a and the multiple data lines 3a can also be distributed in a row. This application does not limit this.

[0050] It should be noted that the plug assembly 10 may be an integrated structure or a split structure. Figure 4 The plug assembly 10 shown is a split structure. In addition, multiple connectors 2a and multiple data lines 3a are distributed in a rectangular array. The plug body 1a includes a fixing frame 11a and multiple split fixings 12a, and the fixing frame 11a and the multiple split fixings 12a are made of insulating materials. Each split fixing 12a fixes a row of connectors 2a and a row of data lines 3a to form a split assembly. Multiple split fixings 12a can fix multiple connectors 2a and multiple data lines 3a. Multiple split fixings 12a can be installed in the fixing frame 11a. A matching hole 110a is provided on the fixing frame 11a, and the fixing member 5a is inserted into the fixing frame 11a through the matching hole 110a. The fixing member 5a is provided with multiple isolation teeth 51a, and the multiple isolation teeth 51a can separate and fix multiple split assemblies.

[0051] For the socket assembly 20 that cooperates with the above-mentioned plug assembly 10, as shown in FIG. Figure 6 , Figure 7 and Figure 8 As shown, the socket assembly 20 includes a socket body 1b, a plurality of second signal terminals 2b, a plurality of data pins 3b and a shielding structure 4b. Figure 8 As shown, the socket body 1b includes a support structure 11b made of insulating material and a plurality of conductive structures 12b made of conductive material. The plurality of second signal terminals 2b are distributed in an array and are spaced apart on the support structure 11b of the socket body 1b. When the number of the second signal terminals 2b is small, the plurality of second signal terminals 2b may also be distributed in a row, and the present application does not limit this. Specifically, the second signal terminals 2b may be arranged as follows: Figure 8The shrapnel structure shown. The second signal terminal 2b can be connected to the above-mentioned first signal terminal 21a to realize signal transmission between the plug assembly 10 and the socket assembly 20. When the connector 400 is used to transmit differential signals, in some examples, multiple second signal terminals 2b constitute multiple pairs of second differential signal pairs 20b. When the socket assembly 20 is connected to the plug assembly 10, each pair of second differential signal pairs 20b can be respectively connected to the corresponding first differential signal pairs 210a in the connector 2a. Multiple pairs of first differential signal pairs 210a can be respectively connected to multiple pairs of second differential signal pairs 20b. Multiple data pins 3b are also distributed in an array and are arranged on the supporting structure 11b of the socket body 1b. Similarly, when the number of data pins 3b is small, multiple data pins 3b can also be distributed in a row, and this application does not impose any restrictions on this. In addition, a plurality of second signal terminals 2b are located at one side edge of the conductive structure 12b of the socket body 1b, and a plurality of data pins 3b are located at another side edge of the conductive structure 12b of the socket body 1b. The above two edges may be opposite or adjacent, and the present application does not impose any restrictions on this. A plurality of conductive structures 12b may be located in the support structure 11b, respectively. A plurality of data pins 3b are respectively connected and conducted with a plurality of second signal terminals 2b through a plurality of conductive structures 12b. A plurality of data pins 3b are used to be plugged into a circuit board (such as the above-mentioned interface board 300). It is understandable that when the socket assembly 20 is used to connect to an optical module or a plug, the data pins 3b may also be replaced with data lines. The shielding structure 4b is connected to the socket body 1b and is arranged around the periphery of the plurality of second signal terminals 2b. The shielding structure 4b is used to isolate the signal transmitted between the plug assembly 10 and the socket assembly 20 from the external environment to reduce crosstalk problems.

[0052] It should be noted that the socket assembly 20 may be an integrated structure or a split structure. Figure 7 The plug assembly 10 shown is a split structure. In addition, the plurality of second signal terminals 2b and the plurality of data pins 3b are distributed in a rectangular array. The socket assembly 20 includes a plurality of conductive sheets made of conductive material and a plurality of supporting structures 11b made of insulating material, and the plurality of conductive sheets are respectively fixed on the plurality of supporting structures 11b. In addition, one or more conductive sheets are fixed in each supporting structure 11b, and the conductive sheets are connected and conducted to one end of a row of second signal terminals 2b and one end of a row of data pins 3b. The plurality of second signal terminals 2b are respectively fixed on the plurality of supporting structures 11b, and the plurality of data pins 3b are also respectively fixed on the plurality of supporting structures 11b.

[0053] In some examples, the shielding structure 4b includes a first shielding plate 41b, a second shielding plate 42b and a plurality of shielding partitions 43b, and the first shielding plate 41b and the second shielding plate 42b are respectively disposed on opposite sides of a row of second signal terminals 2b. Fig. 9 Taking a split structure in the socket assembly 20 shown as an example, for example, the first shielding plate 41b is located on the upper side of a row of second signal terminals 2b, and the second shielding plate 42b is located on the lower side of a row of second signal terminals 2b. The first shielding plate 41b and the second shielding plate 42b are parallel to each other, and can be connected to the support structure 11b of the socket body 1b by welding or riveting. A plurality of shielding baffles 43b are located between the first shielding plate 41b and the second shielding plate 42b, and are connected to the first shielding plate 41b, the second shielding plate 42b, and the support structure 11b of the socket body 1b. Some of the shielding baffles 43b in the plurality of shielding baffles 43b are located between two adjacent second signal terminals 2b in a row of second signal terminals 2b. The remaining two shielding baffles 43b in the plurality of shielding baffles 43b are respectively arranged on the side close to the outside of the two second signal terminals 2b at both ends of a row of second signal terminals 2b. Therefore, multiple shielding partitions 43b, first shielding plates 41b, and second shielding plates 42b can be arranged outside multiple second signal terminals 2b to form multiple signal ports. When the socket assembly 20 is plugged into the plug assembly 10, multiple second signal terminals 2b can be plugged into multiple signal terminals. Multiple second signal terminals 2b can be connected and conducted with multiple first signal terminals 21a, and the grounding member 22a can be plugged into the shielding structure 4b and connected to the shielding structure 4b.

[0054] However, if Fig.10 As shown, the second shielding plate 42b partially overlaps with the grounding member 22a, and the distance between the two is very small, which may cause problems of reflux disturbance and insertion loss resonance, thereby deteriorating the bandwidth performance of the connector 400.

[0055] In order to solve this problem, the second shielding plate 42b of the embodiment of the present application is provided with a Fig.11 and Fig.12 The notch 421b shown in the figure can be opposite to the grounding piece 22a in the corresponding connector 2a. That is, the projection of the grounding piece 22a on the second shielding plate 42b is located at the notch 421b. Therefore, when the plug assembly 10 is connected to the socket assembly 20, the multiple grounding pieces 22a can be located at the multiple notches 421b respectively, and the multiple notches 421b are completely blocked. Therefore, the multiple grounding pieces 22a, the first shielding plate 41b, the second shielding plate 42b, and the multiple shielding partitions 43b form multiple shielding cavities around the multiple second signal terminals 2b and the multiple first signal terminals 21a.

[0056] Therefore, the connector 400 can form a closed shielding cavity around the periphery of the multiple second signal terminals 2b and the multiple first signal terminals 21a. The grounding member 22a can close the gap 421b, reducing the area of ​​the overlapping region between the grounding member 22a and the second shielding plate 42b. Thus, the problems of reflux turbulence and insertion loss resonance caused by the small interval between the overlapping region of the grounding member 22a and the second shielding plate 42b (i.e., the shielding gap) are avoided, and the bandwidth performance of the connector 400 is improved. For example, the insertion loss resonance caused by the shielding gap within the frequency of 30-40GHz is avoided, so that the bandwidth is optimized to 38GHz. Furthermore, the signal transmission integrity and plug-in reliability of the connector 400 are improved.

[0057] It should be noted that when the relative positions of the split socket assembly 20 and the split plug assembly 10 are changed, such as when the first shielding plate 41b is connected to the grounding member 22a of the plug assembly 10, the above-mentioned notch 421b needs to be opened on the first shielding plate 41b. Alternatively, there may be a situation where the grounding member 22a needs to be connected to both the first shielding plate 41b and the second shielding plate 42b, in which case both the first shielding plate 41b and the second shielding plate 42b are provided with the above-mentioned notch 421b. This application does not limit this.

[0058] Among them, the side wall of the above-mentioned notch 421b can be against the grounding piece 22a, so that the second shielding plate 42b is tightly connected to the grounding piece 22a. Alternatively, in some embodiments of the present application, the side wall of the above-mentioned notch 421b is provided with an elastic arm 422b, and the elastic arm 422b can be elastically against the grounding piece 22a plugged into the corresponding signal port. When the socket assembly 20 is plugged into the plug assembly 10, the elastic arm 422b will be squeezed and deformed by the grounding piece 22a. The restoring force of the elastic arm 422b will be pressed against the grounding piece 22a, and the connection force is reliable. Thereby, the connection strength between the grounding piece 22a and the second shielding plate 42b is further improved, and the shielding reliability of the shielding structure is improved.

[0059] It should be noted that in some embodiments, a side wall of the notch 421b is provided with an elastic arm 422b. In other embodiments, a plurality of elastic arms 422b are provided on the side wall of the notch 421b, and the connection strength between the grounding member 22a and the second shielding plate 42b is relatively high. Specifically, a suitable number of elastic arms 422b can be selected according to the physical parameters of the grounding member 22a, such as shape or position.

[0060] The projection of the grounding member 22a on the second shielding plate 42b may completely overlap with the corresponding notch 421b. That is, the projection periphery of the grounding member 22a on the second shielding plate 42b is located outside the notch 421b. Alternatively, the projection of the grounding member 22a on the second shielding plate 42b may only partially overlap with the corresponding notch 421b. That is, only a portion of the projection periphery of the grounding member 22a on the second shielding plate 42b is located outside the notch 421b.

[0061] Since if the projection of the grounding member 22a on the second shielding plate 42b only partially overlaps with the corresponding notch 421b, when the plug assembly 10 and the socket assembly 20 are connected, the grounding member 22a cannot completely cover the notch 421b, and there is a shielding loophole. Therefore, in some embodiments, the projection of the grounding member 22a on the second shielding plate 42b partially overlaps with the corresponding notch 421b. In addition, an elastic arm 422b is provided at the notch 421b, and the elastic arm 422b can cover the gap between the notch 421b and the grounding member 22a, and elastically abut against the grounding member 22a. Thus, the above problem is solved. It can be understood that for the implementation method in which the projection of the grounding member 22a on the second shielding plate 42b can completely overlap with the corresponding notch 421b, the elastic arm 422b can only be used to improve the connection strength between the grounding member 22a and the second shielding plate 42b at the notch 421b.

[0062] For example, Fig.12 The grounding member 22a shown is U-shaped. Therefore, the notch 421b is a rectangular notch or a notch approximately rectangular that is compatible with the U-shaped grounding member 22a. It can be understood that when the grounding member 22a is in the shape of two long strips, the notch 421b is two long strips.

[0063] For the U-shaped grounding member 22a, as Fig.11 As shown, two elastic arms 422b are provided at the notch 421b, and the two elastic arms 422b can respectively abut against the two grounding portions 221a in the grounding member 22a. The abutment force between the second shielding plate 42b and the two grounding portions 221a of the grounding member 22a is uniform and reliable. In addition, in some other embodiments, other even-numbered elastic arms 422b can be provided at the notch 421b, and the even-numbered elastic arms 422b can respectively abut against the two grounding portions 221a in the grounding member 22a.

[0064] In addition to improving the structure of the first shielding plate 41b and / or the second shielding plate 42b, the present application also proposes a solution for improving the shielding partition 43b. Figure 8, a row of shielding partitions 43b includes a plurality of middle shielding partitions 431b and two end shielding partitions 432b. Any middle shielding partition 431b is arranged between two adjacent second signal terminals 2b. A plurality of middle shielding partitions 431b are respectively located between a plurality of second signal terminals 2b. The two end shielding partitions 432b are respectively arranged on one side close to the outside of the second signal terminals 2b at both ends of a row of second signal terminals 2b. For a plurality of shielding partitions 43b distributed in an array, a plurality of end shielding partitions 432b are respectively arranged on one side close to the outside of a plurality of second signal terminals 2b located at the edge of the array.

[0065] by Fig.13 Taking the middle shielding partition 431b shown as an example, the middle shielding partition 431b includes a first shielding partition 4311 and a second shielding partition 4312 parallel to each other, and the first shielding partition 4311 is connected to the second shielding partition 4312. The first shielding partition 4311 is provided with a first elastic claw 4311b, and the second shielding partition 4312 is provided with a second elastic claw 4312b. The first elastic claw 4311b and the second elastic claw 4312b are bent in directions away from each other. That is, the first elastic claw 4311b is bent toward a side close to the second signal terminal 2b in the corresponding signal port. The second elastic claw 4312b is bent toward a side close to the second signal terminal 2b in the corresponding signal port. Thus, the first elastic claw 4311b can abut against the grounding piece 22a in the corresponding signal port. The second elastic claw 4312b can abut against the grounding piece 22a in the corresponding signal port. It can be understood that the number of the first elastic claw 4311 and the number of the second elastic claw 4312b can be one or more, and the present application does not impose any limitation on this. Fig.13 The number of the first elastic claws 4311 and the number of the second elastic claws 4312b shown are both two.

[0066] Specifically, the first elastic claw 4311b and the second elastic claw 4312b can be made by cutting and bending processes. Therefore, there will be gaps in the first shielding baffle 4311 and the second shielding baffle 4312, resulting in an unclosed shielding cavity, poor signal isolation effect, and failure to meet the requirement of 35dB crosstalk at a frequency of 29.5GHz.

[0067] In order to improve the shielding requirements of the intermediate shielding partition 431b, the intermediate shielding partition 431b of the embodiment of the present application further includes: Fig.14 The third shielding baffle 4313 is connected between the first shielding baffle 4311 and the second shielding baffle 4312, and is parallel to the first shielding baffle 4311 and the second shielding baffle 4312. Fig.15As shown. The third shielding partition 4313 is a partition without openings. Therefore, the intermediate shielding partition 431b can not only abut against the grounding pieces 22a in the corresponding two signal ports, but also improve the sealing of the two shielding cavities where the first shielding partition 4311 and the second shielding partition 4312 are located through the intermediate shielding partition 431b, so that the signal isolation effect is good, the crosstalk resonance at the frequency of 30GHz is optimized, and the crosstalk noise at the frequency of 29.5GHz can be optimized by up to 10dB.

[0068] Based on the above structure, in some embodiments, the first shielding baffle 4311 and the second shielding baffle 4312 can be an integral structure. The third shielding baffle 4313 can be snap-fitted with the first shielding plate 41b and the second shielding plate 42b. For example, the first shielding plate 41b and the second shielding plate 42b are formed by bending the same metal plate. The third shielding baffle 4313 can be snap-fitted at the connection between the first shielding plate 41b and the second shielding plate 42b. Fig.13 As shown, a first clamping hole 4310b is provided at the bend of the metal plate, and a first clamping protrusion 4313b is provided on the third shielding baffle 4313, and the first clamping protrusion 4313b can be clamped in the first clamping hole 4310b. The assembly of the components in the middle shielding baffle 431b is convenient, and the manufacturing process is also simple.

[0069] Furthermore, in order to realize the connection between the intermediate shielding partition 431b and the socket body 1b, the first shielding plate 41b, and the second shielding plate 42b, in some embodiments of the present application, the socket body 1b, the first shielding plate 41b, and the second shielding plate 42b are all provided with a second clamping hole 10b. Fig.15 As shown, the third shielding partition 4313 may also be provided with a plurality of second snap-in protrusions 4313c, and the plurality of second snap-in protrusions 4313c respectively correspond to the positions of the second snap-in holes 10b. The plurality of second snap-in protrusions 4313c may respectively snap-in with the second snap-in holes 10b on the socket body 1b, the second snap-in holes 10b on the first shielding plate 41b, and the second snap-in holes 10b on the second shielding plate 42b. It is understandable that the plurality of second snap-in protrusions 4313c may also be provided on the first shielding partition 4311, or on the second shielding partition 4312, or may also be provided on the first shielding partition 4311 and the second shielding partition 4312. The middle shielding partition 431b is convenient to assemble with the socket body 1b, the first shielding plate 41b, and the second shielding plate 42b.

[0070] In some other embodiments, the first shielding baffle 4311, the second shielding baffle 4312 and the third shielding baffle 4313 are an integrated structure. For example, the first shielding baffle 4311, the second shielding baffle 4312 and the third shielding baffle 4313 are formed by a bending process using the same metal plate. Fig.16 As shown, the first shielding partition 4311, the second shielding partition 4312 and the third shielding partition 4313 form an S-shaped shielding partition. The middle shielding partition 431b does not need to be assembled, which reduces the assembly operations of the connector 400.

[0071] In addition, a plurality of third engaging protrusions 4312c may be provided on the first shielding partition 4311 and the second shielding partition 4312. The socket body 1b, the first shielding plate 41b, and the second shielding plate 42b are provided with third engaging holes (not shown in the figure) corresponding to the plurality of third engaging protrusions 4312c. The plurality of third engaging protrusions 4312c may be engaged with the third engaging hole of the socket body 1b, the third engaging hole of the first shielding plate 41b, and the third engaging hole of the second shielding plate 42b, respectively.

[0072] The above is based on Fig. 9 The shielding structure 4b is described by taking a split structure in the socket assembly 20 as an example. For the entire socket assembly 20, the shielding structure 4b may include a plurality of first shielding plates 41b and a plurality of second shielding plates 42b. The plurality of first shielding plates 41b correspond to the plurality of second shielding plates 42b respectively. The plurality of first shielding plates 41b and the plurality of second shielding plates 42b are respectively located on both sides of the plurality of rows of second signal terminals 2b. And, as shown in FIG. Figure 7 As shown, for two adjacent rows of second signal terminals 2b, the first shielding plate 41b of the row of second signal terminals 2b on the left and the second shielding plate 42b of the row of second signal terminals 2b on the right are arranged close to each other. In addition, the first shielding plate 41b of the row of second signal terminals 2b on the left and the second shielding plate 42b of the row of second signal terminals 2b on the right can be connected to each other, such as by welding. Alternatively, the first shielding plate 41b of the row of second signal terminals 2b on the left and the second shielding plate 42b of the row of second signal terminals 2b on the right are an integral structure, such as formed by bending the same metal plate. This application does not impose any restrictions on this.

[0073] In addition, in addition to the above components, in some embodiments of the present application, the socket assembly 20 may also include: Figure 7 The fixing assembly 5b and the cover plate 61b are shown. The fixing assembly 5b includes a first fixing groove 51b and a second fixing groove 52b. The first fixing groove 51b, the second fixing groove 52b and the cover plate 61b can be snap-fitted with the socket body 1b. The first fixing groove 51b is used to fix the above-mentioned shielding structure 4b and separate the multiple shielding cavities formed by the shielding structure 4b. The second fixing groove 52b is used to fix the multiple splits of the socket body 1b and separate the multiple splits of the socket body 1b. The cover plate 61b is used to fix multiple data pins.

[0074] In some other embodiments of the present application, the socket assembly 20 may further include: Fig.17 and Fig.18 The fixing structure 50b and the stopper 62b are respectively connected to the socket body 1b. The fixing structure 50b can fix the shielding structure 4b and accommodate multiple split plug assemblies 10 in the fixing structure 50b. In addition, the fixing structure 50b is provided with a mounting hole. The stopper 62b can be inserted into the fixing structure 50b through the mounting hole. The stopper 62b can Fig.19 The multiple parts of the socket body 10b are separately fixed in the fixing structure 50b.

[0075] It should be noted that the connector of the present application can be applied to various signal transmission scenarios, and there is no restriction on the transmission speed of the connector. Therefore, the connector of the embodiment of the present application can be a high-speed connector or a low-speed connector.

[0076] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
