[0026] (1) Summary

[0027] The following description uses accompanying drawings to illustrate the connectors and connector devices according to embodiments. However, the embodiments described below are only one of the various embodiments of this disclosure. Various modifications can be made to the embodiments described below based on design, etc., as long as the objectives of this disclosure are achieved. Furthermore, the accompanying drawings described in the following embodiments are schematic diagrams, and the proportions of the size and thickness of each structural element in the drawings may not necessarily reflect the actual size ratios.

[0028] like Figure 11 As shown, the connector assembly 100 has a first connector (receptacle S1) and a second connector (plug H1). In the following description, the first connector will also be referred to as "receptacle S1," and the second connector as "plug H1." The receptacle S1 is connected to the plug H1. At this time, terminal 4 of the receptacle S1 is electrically connected to terminal 8 of the plug H1. When viewed from the receptacle S1, the plug H1 is a "partial-side connector" connected to the receptacle S1. Conversely, when viewed from the plug H1, the receptacle S1 is a "partial-side connector" connected to the plug H1. That is, the connector assembly 100 has a connector (receptacle S1 or plug H1) and a partial-side connector. Furthermore, when viewed from the receptacle S1, terminal 8 of the plug H1 is a "partial-side terminal" electrically connected to terminal 4 of the receptacle S1. Conversely, when viewed from the plug H1, terminal 4 of the receptacle S1 is a "partial-side terminal" electrically connected to terminal 8 of the plug H1.

[0029] (1.1) Structure 1

[0030] like Figure 1 , Figure 5 , Figure 9 as well as Figure 13As shown, the connector (receptacle S1 or plug H1) of this embodiment has an outer shield 1 (or 5), a terminal 4 (or 8), a housing 2 (or 6), and an inner shield 3 (or 7). The terminal 4 (or 8) is surrounded by the outer shield 1 (or 5). The terminal 4 (or 8) is electrically connected to the object-side terminal of the object-side connector. The outer shield 1 (or 5) is fixed relative to the housing 2 (or 6). The housing 2 (or 6) holds the terminal 4 (or 8). The inner shield 3 (or 7) is surrounded by the outer shield 1 (or 5). The inner shield 3 (or 7) includes two tip regions r1 (or r7). The two tip regions r1 (or r7) include a tip region r1 (or r7) opposite to or directly coupled to the outer shield 1 (or 5) and a tip region r1 (or r7) opposite to or directly coupled to the outer shield 1 (or 5). In the multiple electrical loops described below, the longest loop length of electrical loops LO1, LO2, and LO3 that do not surround other electrical loops is shorter than the wavelength of the maximum frequency of the transmitted signal flowing to terminal 4 (or 8). The two top regions r1 (or r7) are connected to the outer shield 1 (or 5) via two imaginary paths W7 and W8 (or W9 and W10) through the shortest distance L1 (or L7), respectively. Multiple electrical loops surround terminal 4 (or 8) through the outer shield 1 (or 5), the inner shield 3 (or 7), and the two imaginary paths W7 and W8 (or W9 and W10), respectively. When viewed from the socket S1, the inner shield 7 of the plug H1 is the object-side inner shield. Conversely, when viewed from the plug H1, the inner shield 3 of the socket S1 is the object-side inner shield. When viewed from the socket S1, the outer shield 5 of the plug H1 is the object-side outer shield. Conversely, when viewed from the plug H1, the outer shield 1 of the socket S1 is the object-side outer shield.

[0031] Based on the above structure, the possibility of resonance of transmitted signals occurring in the electrical closed loop can be reduced.

[0032] In this disclosure, "maximum frequency of the transmitted signal flowing to the terminal" refers to, in the case of transmitting signals via the terminal, for example, the maximum frequency of the carrier wave of the signal when transmitting radio frequency (RF) signals, and the frequency of a higher harmonic of 3 to 5 times the clock frequency when transmitting digital signals. The aforementioned maximum frequency is, for example, a value determined by the connector manufacturer based on the connector design or by the connector specifications. The aforementioned maximum frequency is, for example, a value described in the manufacturer's design specifications as the maximum frequency at which operation is guaranteed.

[0033] (1.2) Structure 2

[0034] In addition, such as Figure 1 , Figure 4 , Figure 5 , Figure 8 as well as Figure 9 As shown, the connector (socket S1 or plug H1) of this embodiment has an outer shield 1 (or 5), terminals 4 (or 8), and a housing 2 (or 6). The outer shield 1 (or 5) has a cylindrical portion 10 (or 50). The cylindrical portion 10 (or 50) is open at both ends in a predetermined direction. Terminals 4 (or 8) are surrounded by the outer shield 1 (or 5). Terminals 4 (or 8) are electrically connected to the target-side terminals of the target-side connector. The outer shield 1 (or 5) is fixed relative to the housing 2 (or 6). The housing 2 (or 6) holds terminals 4 (or 8). The outer shield 1 (or 5) has a top surface 102 (or 502), an outer peripheral surface 101 (or 501) of the cylindrical portion 10 (or 50), and an inner peripheral surface 103 (or 503) of the cylindrical portion 10 (or 50). The top surface 102 (or 502) is provided at one of the following ends of the cylindrical portion 10 (or 50), along the inner edge of the cylindrical portion 10 (or 50). "One end" refers to the end that becomes the side of the object-side connector when the connection between the connector and the object-side connector changes from a non-connected state to a connected state. At least one of the top surface 102 (or 502), the outer peripheral surface 101 (or 501), and the inner peripheral surface 103 (or 503) is seamless along the entire circumference of the cylindrical portion 10 (or 50) in the circumferential direction D10 (or D50).

[0035] In this disclosure, "seamless" means that there are no seams or cracks.

[0036] According to the above structure, compared with the case where there are seams or cracks on the top surface 102 (or 502), the outer peripheral surface 101 (or 501) and the inner peripheral surface 103 (or 503) respectively, the noise radiated from the outer shield 1 (or 5) can be reduced.

[0037] In connectors described in Japanese Patent Application Publication No. 2013-182808, radiated noise can sometimes still be generated even when a shielding cover is installed.

[0038] In contrast, the connector of this embodiment, as described above, is able to reduce noise radiated from the outer shield 1 (or 5).

[0039] (1.3) Structure 3

[0040] In addition, such as Figure 1 , Figure 5 as well as Figure 10As shown, the connector (receptacle S1 or plug H1) of this embodiment has a plurality of terminals 4 (or 8). The plurality of terminals 4 (or 8) are electrically connected to a plurality of object-side terminals of the object-side connector. The connector also has a housing 2 (or 6) and an inner shield 3 (or 7). The housing 2 (or 6) holds the plurality of terminals 4 (or 8). The connector and the object-side connector are connected to each other by at least one moving toward the other in the vertical direction Dud. The plurality of terminals 4 (or 8) includes two terminals 4 (or 8). The two terminals 4 (or 8) are arranged on both sides in the front-back direction Dfb, which is orthogonal to the vertical direction Dud, separated by the inner shield 3 (or 7). The inner shield 3 (or 7) has a base 31 (or 71) and an extension 32 (or 72). The base 31 (or 71) extends along the left-right direction Dlr, which is orthogonal to the vertical direction Dud and the front-back direction Dfb. The extension 32 (or 72) protrudes from the base 31 (or 71) in the vertical direction. The housing 2 (or 6) has a shielding retainer (receiving portion 28 or 68). The shielding retainer holds the extension 32 (or 72).

[0041] According to the above structure, with two terminals 4 (or 8) positioned on both sides across the inner shield 3 (or 7), the possibility of noise transmission between the two terminals 4 (or 8) can be reduced compared to the case without the inner shield 3 (or 7). Furthermore, since the connector extension 32 (or 72) is positioned by the shield holding portion (receiving portion 28 or 68), the alignment accuracy between the connector extension 32 (or 72) and the target connector can be improved. In this embodiment, the connector extension 32 (or 72) is electrically connected to the inner shield of the target connector. According to the above structure, the accuracy of the electrical connection between the connector extension 32 (or 72) and the inner shield of the target connector can be improved.

[0042] In connectors as described in Japanese Patent Application Publication No. 2013-182808, there are cases where noise is transmitted between multiple contacts (terminals) and radiated noise is generated.

[0043] In contrast, in the connector of this embodiment, as described above, the possibility of noise transmission between the two terminals 4 (or 8) can be reduced.

[0044] (1.4) Structure 4

[0045] In addition, such as Figure 1 , Figure 2 , Figure 5 as well as Figure 6As shown, the connector (receptacle S1 or plug H1) of this embodiment has multiple terminals 4 (or 8), a housing 2 (or 6), and an inner shield 3 (or 7). The multiple terminals 4 (or 8) are electrically connected to multiple object-side terminals of the object-side connector. The housing 2 (or 6) holds the multiple terminals 4 (or 8). The connector and the object-side connector are connected to each other by at least one moving toward the other in the vertical direction Dud. In this embodiment, the receptacle S1, as the connector, is configured to move relative to the plug H1, which is the object-side connector, toward the plug H1 and toward the upward direction Du, which is a predetermined direction, thereby connecting to the plug H1. The multiple terminals 4 (or 8) include two terminals 4 (or 8). The two terminals 4 (or 8) are arranged on both sides in the front-back direction Dfb, orthogonal to the vertical direction Dud, separated by the inner shield 3 (or 7).

[0046] Based on the above structure, compared with the case without the inner shield 3 (or 7), the possibility of noise transmission between the two terminals 4 (or 8) can be reduced.

[0047] In addition, in the above structure, the connector preferably also has an outer shield 1 (or 5). The outer shield 1 (or 5) surrounds a plurality of terminals 4 (or 8) and an inner shield 3 (or 7).

[0048] By having an outer shield 1 (or 5) on the connector, the possibility of noise transmission or radiation between the inside and outside of the outer shield 1 (or 5) can be reduced.

[0049] (2) Detailed explanation

[0050] The following is for reference Figures 1 to 14 The connector (socket S1 and plug H1) of this embodiment will be described in detail below.

[0051] Unless otherwise specified, the direction in which socket S1 and plug H1 are connected or separated will be defined as the vertical direction Dud, and when viewed from socket S1, the plug H1 side will be defined as the upward direction Du. Furthermore, the direction perpendicular to the vertical direction Dud and being the long side of the casing 2 of socket S1 will be defined as the front-back direction Dfb. Additionally, the direction perpendicular to both the vertical direction Dud and the front-back direction Dfb, i.e., the short side of the casing 2, will be defined as the left-right direction Dlr. In other words, in... Figure 1 In the diagram, the directions are indicated by arrows for "up," "down," "front," "back," "left," and "right," signifying the directions as follows: up (Du), down (Dd), front (Df), back (Db), left (Dl), and right (Dr). However, these directions do not specify the intended use of the socket S1 and plug H1. Furthermore, the arrows indicating the directions in the diagram are for illustrative purposes only and do not correspond to actual objects.

[0052] As described above, the connector and the object-side connector are connected to each other by at least one moving toward the other in the vertical direction Dud. In this embodiment, the socket S1 is positioned below the plug H1, and the socket S1 and the plug H1 can be connected to each other by performing at least one of the actions of moving the socket S1 upward in the vertical direction Du and moving the plug H1 downward in the vertical direction Dd. Therefore, "when transitioning from a non-connected state to a connected state of the connector and the object-side connector, the object-side connector side" means the upper side when the socket S1 is the connector, and the lower side when the plug H1 is the connector.

[0053] In this embodiment, the socket S1 and the plug H1 are respectively mounted on a circuit board 150 or 550, such as a printed wiring board or a flexible printed wiring board (see reference). Figure 10 The socket S1 and plug H1 are used to electrically connect multiple circuit boards, such as those in a portable terminal like a smartphone. However, this is not to limit the use of the socket S1 and plug H1; they can also be used in electronic devices other than portable terminals, such as camera modules. Furthermore, the use of the socket S1 and plug H1 is not limited to electrically connecting multiple circuit boards; for example, it can be used to electrically connect multiple components, such as between a circuit board and a display, or between a circuit board and a battery.

[0054] The socket S1 and the plug H1 can be provided either when not connected to the circuit board 150 or 550, or when connected to the circuit board 150 or 550.

[0055] (2.1) Structure of the socket

[0056] First, the structure of the socket S1 in this embodiment will be explained.

[0057] Socket S1 is doubly symmetrical about the axis passing through its center and along the vertical direction Dud. For example... Figure 1 As shown, the socket S1 has an outer shield 1, a housing 2, multiple (two) inner shields 3, and multiple (eight) terminals 4. Each inner shield 3 of the outer shield 1 and the multiple inner shields 3 is an electrostatic shield. The outer shield 1 surrounds the multiple terminals 4. That is, the outer shield 1 is disposed on the outside of the multiple terminals 4. The multiple inner shields 3 are disposed on the inside of the outer shield 1. Furthermore, the multiple inner shields 3 are disposed on the inside of the housing 2.

[0058] Circuit board 150 (reference) Figure 9It is mechanically and electrically connected to the socket S1. In this embodiment, the circuit board 150 is a double-sided substrate, but the circuit board 150 may also be a laminated substrate. The circuit board 150 has a substrate 160 (see reference). Figure 9 ) and conductors 170, 180 (refer to) Figure 9 The substrate 160 is, for example, a semiconductor substrate or a glass substrate. The conductor 170 is a pattern of copper foil or the like provided on the surface of the substrate 160. The conductor 170 is, for example, provided on the entire surface of the substrate 160 on the side where the socket S1 is connected. The conductor 180 is, for example, solder. The conductor 180 is provided in a predetermined area (pad) of the conductor 170. The conductor 170 is electrically connected to the outer shield 1, a plurality of inner shields 3, and a plurality of terminals 4 via the conductor 180 (solder). The outer shield 1 and the plurality of inner shields 3 are, for example, electrically connected to a ground portion provided on the circuit board 150. Figure 2 In the diagram, a two-dot dashed line is used to indicate the area where the conductor 180 (solder) is located.

[0059] (2.1.1) Socket housing

[0060] The housing 2 is a resin molded body. The housing 2 is electrically insulating. For example... Figures 1-3 As shown, the housing 2 has a bottom wall 21 and a peripheral wall 22. The bottom wall 21 is formed into a rectangle that is longer in the front-rear direction Dfb than in the left-right direction Dlr when viewed from above. The peripheral wall 22 protrudes in the upward direction Du from the outer periphery of one side (upper surface) of the bottom wall 21 in the thickness direction. The housing 2 is a flat cuboid that extends orthogonally to the vertical direction Dud. At the center of the upper surface of the two faces of the vertical direction Dud that are opposite to the plug H1, there is a recess 24 surrounded by the peripheral wall 22 (see reference). Figure 3 ).

[0061] The peripheral wall 22 is cylindrical in shape. The peripheral wall 22 surrounds multiple terminals 4. The peripheral wall 22 has a circumferential direction D22 (refer to...). Figure 1 The circumference of the peripheral wall 22 is continuous. In other words, the peripheral wall 22 is formed such that there are no cracks along the entire circumference of the circumferential direction D22 of the peripheral wall 22. Figure 1 As shown, the peripheral wall 22 includes two peripheral walls 221 and two peripheral walls 222. The two peripheral walls 221 are portions of the peripheral wall 22 that extend approximately parallel to the front-rear direction Dfb, and are opposite each other in the left-right direction Dlr, separated by a recess 24. The two peripheral walls 222 are portions of the peripheral wall 22 that extend approximately parallel to the left-right direction Dlr, and are opposite each other in the front-rear direction Dfb, separated by a recess 24. The two peripheral walls 222 connect the ends of the two peripheral walls 221 to each other. That is, the housing 2 has a shape in which one opening (lower surface) of the square-section cylindrical peripheral wall 22 is closed by the bottom wall 21.

[0062] like Figure 3As shown, the shell 2 also has wall portions 25, 26, and 27. Wall portions 25, 26, and 27 protrude upwards (Du) from the bottom wall 21. Wall portions 25, 26, and 27 are disposed within the recess 24. That is, wall portions 25, 26, and 27 are surrounded by a peripheral wall 22. Wall portions 25, 26, and 27 are each rectangular parallelepiped in shape. When viewed along the vertical direction (Dud), each of wall portions 25, 26, and 27 is longer in the front-rear direction (Dfb) than in the left-right direction (Dlr). That is, each of wall portions 25, 26, and 27 is a wall portion with thickness along the left-right direction (Dlr). Wall portions 25, 26, and 27 are arranged sequentially from left to right, i.e., arranged in the rightward direction (Dr).

[0063] Each of the multiple wall portions (wall portion 25, wall portion 26, and wall portion 27) has multiple (two) receiving portions 28. Each receiving portion 28 receives an extension 32 of the inner shielding member 3. Each receiving portion 28 is a through hole provided in the wall portion. The receiving portion 28 penetrates the wall portion in the vertical direction Dud. The receiving portion 28 also penetrates the bottom wall 21 in the vertical direction Dud. Furthermore, when viewed along the vertical direction Dud, the receiving portions 28 provided in wall portions 25 and 27 are recesses from the side of wall portion 25 (wall portion 27) (the surface intersecting the horizontal direction Dur).

[0064] Furthermore, each of the multiple wall portions (wall portion 25, wall portion 26, and wall portion 27) has multiple terminal holding portions 29. Each of the multiple terminal holding portions 29 holds a terminal 4. Each of the multiple terminal holding portions 29 is a through hole provided in the wall portion. The through hole extends through the terminal holding portion 29 in the vertical direction Dud. In addition, when viewed along the vertical direction Dud, the terminal holding portion 29 is a recessed portion from the side of the wall portion (the surface that intersects with the horizontal direction Dlr). The multiple terminal holding portions 29 are arranged in pairs, with two corresponding terminal holding portions 29 arranged in the horizontal direction Dlr. Furthermore, the portion between two corresponding terminal holding portions 29 in the bottom wall 21 is a through hole 211 for the insertion of the terminal 4.

[0065] Multiple terminals 4 are fixed to the housing 2 by pressing. That is, multiple terminals 4 are held by the housing 2 by being pressed into the housing 2 in one direction (upward). In this embodiment, eight terminals 4 are fixed to the housing 2. The eight terminals 4 are arranged in two rows. That is, four of the eight terminals 4 constitute the first row, and the remaining four terminals 4 constitute the second row. The four terminals 4 in each row are arranged in the front-rear direction Dfb. The four terminals 4 constituting the first row are held by the terminal holding portion 29 of the wall portion 25 and the terminal holding portion 29 of the wall portion 26, respectively. The four terminals 4 constituting the second row are held by the terminal holding portion 29 of the wall portion 26 and the terminal holding portion 29 of the wall portion 27, respectively. That is, each terminal 4 is disposed between the two wall portions and supported by the two wall portions from both sides.

[0066] like Figure 2 As shown, the bottom wall 21 has multiple notches 212. These notches 212 are positioned opposite the substrate connection portion 45 of the terminal 4 (described later) when viewed along the vertical direction Dud. Additionally, the bottom wall 21 has multiple (two) receiving slots 213. Each receiving slot 213 is a groove provided on the lower surface of the bottom wall 21. The receiving slot 213 is longer in the horizontal direction Dlr than in the front-back direction Dfb. The receiving slot 213 receives the base 31 of the inner shielding member 3.

[0067] The peripheral wall 22 has a plurality of (4) insertion portions 223. The plurality of (4) insertion portions 223 are recesses that are recessed from the side surfaces (inner surfaces) of the two peripheral walls 221 and the two peripheral walls 222 respectively. As will be described later, shielding protrusions 14, which are part of the outer shielding member 1, are inserted into the plurality of (4) insertion portions 223 respectively.

[0068] (2.1.2) External shielding of the socket

[0069] The outer shield 1 surrounds multiple terminals 4 and multiple inner shields 3. The outer shield 1 comprises a material such as metal as the main material or a plating layer forming the surface. Here, as an example, the outer shield 1 is formed primarily of metal. Figure 1 , Figure 4 As shown, the outer shield 1 has a cylindrical portion 10 and a plurality of (4) shield protrusions 14. The cylindrical portion 10 includes an outer peripheral wall 11, a top wall 12, and an inner peripheral wall 13.

[0070] The outer peripheral wall 11 has a square cylindrical shape with a rectangular cross-section. The outer peripheral wall 11 includes two outer peripheral walls 111 and two outer peripheral walls 112. The two outer peripheral walls 111 are portions of the outer peripheral wall 11 that extend approximately parallel to the front-rear direction Dfb and are opposite each other in the left-right direction Dlr. The two outer peripheral walls 112 are portions of the outer peripheral wall 11 that extend approximately parallel to the left-right direction Dlr and are opposite each other in the front-rear direction Dfb. The two outer peripheral walls 112 connect the ends of the two outer peripheral walls 111 to each other. The lower ends (lower surfaces) of each of the outer peripheral walls 111 and 112 are parallel to planes extending in the front-rear direction Dfb and the left-right direction Dlr, and are formed in approximately the same plane.

[0071] The top wall 12 is rectangular when viewed in the vertical direction (Dud). The top wall 12 is connected to the upper end of the outer peripheral wall 11 and extends towards the inner side of the outer peripheral wall 11 when viewed in the vertical direction (Dud).

[0072] The inner peripheral wall 13 is located inside the outer peripheral wall 11. The inner peripheral wall 13 has a square cylindrical shape with a square cross-section. The upper end of the outer peripheral wall 11 and the upper end of the inner peripheral wall 13 are connected by a top wall 12.

[0073] The inner peripheral wall 13 includes two inner peripheral walls 131 and two inner peripheral walls 132. The two inner peripheral walls 131 are portions of the inner peripheral wall 13 that extend approximately parallel to the front-rear direction Dfb and are opposite each other in the left-right direction Dlr. The two inner peripheral walls 132 are portions of the inner peripheral wall 13 that extend approximately parallel to the left-right direction Dlr and are opposite each other in the front-rear direction Dfb. The two inner peripheral walls 132 connect the ends of the two inner peripheral walls 131 to each other.

[0074] A cylindrical portion 10, with openings at both ends in the vertical direction Dud, is formed by an outer peripheral wall 11, a top wall 12, and an inner peripheral wall 13. The outer peripheral surface of the outer peripheral wall 11 corresponds to the outer peripheral surface 101 of the cylindrical portion 10. The inner peripheral surface of the inner peripheral wall 13 corresponds to the inner peripheral surface 103 of the cylindrical portion 10. Additionally, the outer shield 1 has a top surface 102. The top surface 102 is located at one end (upper end) of the cylindrical portion 10 in the vertical direction Dud, which becomes the target connector side when transitioning from a non-connected state (here, socket S1) to a connected state with the target connector (here, plug H1). The top surface 102 is annular along the inner edge of the cylindrical portion 10. Here, the upper surface of the top wall 12 corresponds to the top surface 102. Furthermore, the inner edge of the top surface 102 corresponds to the inner edge of the cylindrical portion 10 at its upper end.

[0075] The boundary portion b1 between the top surface 102 and the outer peripheral surface 101 is an arc-shaped surface when viewed along the front-to-back direction Dfb (see reference). Figure 9Additionally, the boundary portion b2 between the top surface 102 and the inner peripheral surface 103 appears as an arc-shaped surface when viewed along the front-to-back direction Dfb (see reference). Figure 9 Furthermore, here, the top surface 102 is defined as the region on the outer surface of the cylindrical portion 10 where the acute angle formed with respect to the vertical direction Dud is 0 degrees or more and less than 45 degrees. Additionally, the outer surface with an acute angle of 45 degrees or more is defined as the outer peripheral surface 101, and the inner surface with an acute angle of 45 degrees or more is defined as the inner peripheral surface 103. The cylindrical portion 10 surrounds the hollow portion 10S. The boundary portion b1 is defined as the area in the circumferential direction D10 surrounding the hollow portion 10S of the cylindrical portion 10 (refer to...). Figure 4 The boundary portion b2 is defined as including a portion of the top surface 102 and a portion of the outer peripheral surface 101 on the entire circumference of the cylindrical portion 10 in the circumferential direction D10.

[0076] Multiple (four) shielding protrusions 14 are provided one on each of the two inner peripheral walls 131 and the two inner peripheral walls 132. Each shielding protrusion 14 protrudes downward from the corresponding inner peripheral wall 131 or inner peripheral wall 132. The multiple (four) shielding protrusions 14 correspond to multiple (four) insertion portions 223 provided on the housing 2 (see reference). Figure 2 One-to-one correspondence. Each shielding protrusion 14 is inserted into the corresponding insertion part 223.

[0077] The outer shield 1 is embedded in the housing 2. More specifically, the outer shield 1 is embedded in the housing 2 such that the peripheral wall 22 of the housing 2 enters between the outer peripheral wall 11 and the inner peripheral wall 13 of the outer shield 1.

[0078] The outer shield 1 is formed seamlessly over its entire surface. The outer shield 1 is formed, for example, by deep drawing, thereby forming a seamless surface across its entire surface. In this embodiment, at least the outer peripheral surface 101 and the inner peripheral surface 103 of the outer shield 1 are seamless (i.e., without seams or cracks) over the entire circumferential direction D10 of the cylindrical portion 10. Furthermore, in this embodiment, the top surface 102 is seamless over the entire circumferential direction D10 of the cylindrical portion 10.

[0079] For example, when focusing on the outer peripheral surface 101, such as Figure 4 As shown, the outer peripheral surface 101 includes the outer surfaces 1110 of each of the two outer peripheral walls 111 and the outer surfaces 1120 of each of the two outer peripheral walls 112. The outer surfaces 1110 and 1120 are seamless. Furthermore, the two surfaces with different normal directions, namely the outer surfaces 1110 and 1120, are seamlessly connected. Thus, the outer peripheral surface 101 is seamless along the entire circumferential direction D10 of the cylindrical portion 10.

[0080] Additionally, when focusing on the inner circumferential surface 103, such as Figure 4 As shown, the inner circumferential surface 103 includes the outer surfaces 1310 of each of the two inner circumferential walls 131 and the outer surfaces 1320 of each of the two inner circumferential walls 132. The outer surfaces 1310 and 1320 are seamless. Furthermore, the two surfaces with different normal directions, namely the outer surfaces 1310 and 1320, are seamlessly connected. Thus, the inner circumferential surface 103 is seamless over the entire circumferential direction D10 of the cylindrical portion 10.

[0081] In addition, at least one of the boundary portion b1 between the top surface 102 and the outer peripheral surface 101 and the boundary portion b2 between the top surface 102 and the inner peripheral surface 103 (both in this embodiment) is seamless over the entire circumference of the cylindrical portion 10 in the circumferential direction D10.

[0082] For example, in Figure 4 At the upper right position of the paper (the corner of the outer shield 1), the outer surface 1110 of the outer peripheral wall 111, the outer surface 1120 of the outer peripheral wall 112, and the top surface 102 are seamlessly connected. That is, the three surfaces with different normal directions—outer surface 1110, outer surface 1120, and top surface 102—are seamlessly connected. Furthermore, in Figure 4 On the right side of the paper, the two surfaces with different normal directions, namely the outer surface 1110 and the top surface 102, are seamlessly connected. Furthermore, in Figure 4 Above the paper surface, the two surfaces with different normal directions, namely the outer surface 1120 and the top surface 102, are seamlessly connected. Thus, the boundary portion b1 is seamless over the entire circumference D10 of the cylindrical portion 10.

[0083] Additionally, for example, in Figure 4 At the lower left corner of the paper (corner of the outer shield 1), the outer surface 1310 of the inner peripheral wall 131, the outer surface 1320 of the inner peripheral wall 132, and the top surface 102 are seamlessly connected. That is, the three surfaces with different normal directions—outer surface 1310, outer surface 1320, and top surface 102—are seamlessly connected. Furthermore, in Figure 4 On the left side of the paper, the two surfaces with different normal directions, namely the outer surface 1310 and the top surface 102, are seamlessly connected. Furthermore, in Figure 4 Below the paper, the two surfaces with different normal directions, namely the outer surface 1320 and the top surface 102, are seamlessly connected. Thus, the boundary portion b2 is seamless over the entire circumference D10 of the cylindrical portion 10.

[0084] (2.1.3) Inner shielding of the socket

[0085] In this embodiment, the two inner shielding members 3 have the same shape. The inner shielding member 3 comprises metal as the main material or a material constituting a surface plating, etc. Here, as an example, the inner shielding member 3 is formed primarily of metal. Figure 1 , Figure 9 As shown, the inner shield 3 has a base 31 and a plurality of (3) extensions 32 (two extensions 33 and one extension 34).

[0086] The base 31 has a length along the left-right direction Dlr. The base 31 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of the base 31, the base 31 is longer in the left-right direction Dlr than in the up-down direction Dud. The base 31 is housed in a receiving groove 213 provided on the bottom wall 21 of the housing 2.

[0087] like Figure 9 As shown, multiple extensions 32 protrude upwards from the base 31. That is, the multiple extensions 32 protrude along the vertical direction Dud, facing the direction that becomes the target connector side when transitioning from a non-connected state to a connected state between the connector (here, socket S1) and the target connector (here, plug H1). Each extension 32 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of each extension 32, each extension 32 is longer in the vertical direction Dud than in the horizontal direction Dlr. Alternatively, the thickness direction of each extension 32 could also be the horizontal direction Dlr.

[0088] The extension portion 33 includes an extension body 331 and an abutment portion 332. The extension body 331 is a portion that protrudes from the base 31. The abutment portion 332 is a portion that contacts the inner shield (inner shield 7) on the object side of the object-side connector (plug H1). The abutment portion 332 protrudes from the extension body 331 in the length direction (direction D1 or direction Dr). The abutment portion 332 is provided on a surface 332S (here, the left or right side) of the extension portion 33 (extension body 331) along the length direction of the extension portion 33. That is, the abutment portion 332 protrudes from the extension body 331 in the left-right direction D1r.

[0089] The abutting portions 332 of the two extensions 33 are opposite each other in the left-right direction (Dlr). When the socket S1 is connected to the plug H1, each abutting portion 332 is configured to contact the abutting portion 720 of the inner shield 7 of the plug H1 (see reference). Figure 10 Therefore, the two inner shields 3 are electrically connected to the corresponding inner shields 7 of the two inner shields 7 of the plug H1. Specifically, the two extensions 72 of the inner shield 7 are inserted between the two extensions 33 of the inner shield 3. At this time, under the elastic action of the two extensions 72 and the two extensions 33, the two extensions 72 are pressed by the two extensions 33.

[0090] The extension portion 34 includes an extension portion body 341 and a plurality of (two) retaining protrusions 342. The extension portion body 341 is a portion that protrudes from the base 31. The two retaining protrusions 342 protrude from the extension portion body 341. The two retaining protrusions 342 are located at the left and right ends of the extension portion body 341. That is, one of the two retaining protrusions 342 protrudes to the left (D1) from the extension portion body 341, and the other protrudes to the right (Dr) from the extension portion body 341.

[0091] The socket S1 has three extensions 32 on each of the two inner shielding members 3. That is, the socket S1 has a total of six extensions 32. Six storage portions 28 are provided in the housing 2 (see reference). Figure 3 Each of the six extensions 32 corresponds one-to-one. Each extension 32 is housed in a corresponding housing 28. More specifically, the housing 28s of the wall portions 25 and 27 house extensions 33, and the housing 28 of the wall portion 26 houses extensions 34. In the extension 34, the width of the left-right direction Dlr, including the two retaining protrusions 342, is slightly larger than the width of the left-right direction Dlr of the housing 28. The inner shield 3 is fixed to the housing 2 by pressing. That is, the inner shield 3 is held by the housing 2 by being pressed into the housing 2 in one direction (upward). The inner shield 3 is held by the housing 2 with the two retaining protrusions 342 clamped by the inner surface of the housing 28.

[0092] Here, the storage space of each of the two extensions 33 in the shield holding portion (receiving portion 28) is larger than the two extensions 33 themselves. That is, there is a clearance between the two extensions 33 and the inner surface of the receiving portion 28. The function of holding the inner shield 3 in the housing 2 is achieved by at least the extension 34. That is, the inner shield 3 is held by the housing 2 by at least the extension 34 being pressed into the receiving portion 28. In summary, the plurality of extensions 32 include: an extension 33 including an abutment portion 332 that contacts the inner shield 7 of the target connector (plug H1 in this case); and an extension 34 that is held by the shield holding portion (receiving portion 28). However, the extension 34 may also include an abutment portion that contacts the inner shield 7 of the target connector (plug H1 in this case).

[0093] like Figure 9 As shown, the base 31 of the inner shield 3 is located at the lower end of the socket S1. The inner shield 3 is surrounded by the outer shield 1. The inner shield 3 includes two top regions r1 opposite to the outer shield 1. The two top regions r1 are located at both ends (left and right ends) of the base 31 in the length direction.

[0094] Here, the outer shield 1 has an end e1 and an end e2. End e1 is the end (upper end) that becomes the side of the target connector when transitioning from a non-connected state to a connected state between the connector (here, socket S1) and the target connector (here, plug H1). End e2 is the end (lower end) that is opposite to end e1. Furthermore, here, end e2 is defined as a region covering the entire circumference D10 of the cylindrical portion 10. The outer shield 1 is opposite to the two top end regions r1 in the region including end e2.

[0095] The outer shield 1 is positioned opposite to at least one of the two top regions r1, separated by a gap g1, in the region including end e2. Figure 9 As shown, conductors 170 and 180 of the circuit board 150 are electrically connected to the outer shield 1. Furthermore, conductors 170 and 180 are configured to support the ends e2 of the outer shield 1 on the two top regions r1 of the inner shield 3, respectively. In other words, the outer shield 1 is electrically connected to the inner shield 3 via conductors 170 and 180. On the other hand, in the absence of the circuit board 150, the outer shield 1 is electrically insulated from at least one of the two top regions r1 (both in this embodiment) through a gap g1. The shortest distance L1 between the outer shield 1 in the gap g1 and at least one of the two top regions r1 is 0.01 mm or more and 0.1 mm or less.

[0096] The inner shield 3 has an end e3 and an end e4. End e3 is the end (upper end) that becomes the target connector side when transitioning from a non-connected state to a connected state between the connector (here, socket S1) and the target connector (here, plug H1). End e4 is the end (lower end) that is opposite to end e3. The inner shield 3 has a connection surface 310 (lower surface) at end e4 that is electrically connected to the circuit board 150. The connection surface 310 is planar and continuous across the two top regions r1. More specifically, the connection surface 310 is a rectangular plane that connects the two top regions r1.

[0097] (2.1.4) Terminals of the socket

[0098] (2.1.4.1) Configuration

[0099] like Figure 2 , Figure 3 As shown, the plurality of (8) terminals 4 include a plurality of (6) low-frequency terminals 4P and a plurality of (2) high-frequency terminals 4T. Each terminal 4 is inserted into a through hole 211 in the bottom wall 21 of the housing 2 and is held by a terminal holding part 29.

[0100] Two high-frequency terminals 4T are disposed on both sides, separated by at least one inner shield 3. In other words, at least one inner shield 3 is disposed between the two high-frequency terminals 4T. This reduces the possibility of noise transmission between the two high-frequency terminals 4T.

[0101] More specifically, two high-frequency terminals 4T are arranged on both sides of at least one inner shield 3 in the front-rear direction Dfb, i.e., on the front and rear sides of the inner shield 3. Figure 2 In this configuration, focusing on one of the two inner shielding members 3, a high-frequency terminal 4T is positioned in front of the inner shielding member 3, i.e., in the forward direction Df from the inner shielding member 3, and the remaining high-frequency terminal 4T is positioned behind the inner shielding member 3, i.e., in the rearward direction Db from the inner shielding member 3. Furthermore, two inner shielding members 3 are positioned between the two high-frequency terminals 4T. Additionally, the length direction (left-right direction Dlr) of the inner shielding member 3 intersects the direction in which the two high-frequency terminals 4T are arranged (essentially the front-back direction Dfb).

[0102] Six low-frequency terminals 4P are disposed between two inner shields 3. That is, the space where one of the two high-frequency terminals 4T is disposed and the space where the six low-frequency terminals 4P are disposed are separated by one of the two inner shields 3. Furthermore, the space where the other of the two high-frequency terminals 4T is disposed and the space where the six low-frequency terminals 4P are disposed are separated by the other of the two inner shields 3. The six low-frequency terminals 4P are arranged in two columns of three in each column along the front-to-back direction Dfb.

[0103] The three low-frequency terminals 4P in each column are arranged at equal intervals along the front-to-back direction Dfb. Additionally, a high-frequency terminal 4T is positioned in front of or behind the low-frequency terminal 4P at the end of each column; that is, a high-frequency terminal 4T is positioned in the front-to-back direction Df or the rear-to-back direction Db, starting from the low-frequency terminal 4P at the end of each column. The spacing between the low-frequency terminal 4P and the high-frequency terminal 4T is an integer multiple of the spacing between the three low-frequency terminals 4P (twice in this embodiment). This arrangement allows for easy assembly of six low-frequency terminals 4P and two high-frequency terminals 4T into the housing 2.

[0104] In this embodiment, the spacing between the low-frequency terminal 4P and the high-frequency terminal 4T is longer than the spacing between the three low-frequency terminals 4P. This ensures sufficient space for the inner shield 3 to be positioned between the low-frequency terminal 4P and the high-frequency terminal 4T.

[0105] Because a space is provided between the two high-frequency terminals 4T for accommodating multiple low-frequency terminals 4P, the distance between the two high-frequency terminals 4T can be ensured. This further reduces the possibility of noise transmission between the two high-frequency terminals 4T. Furthermore, the two high-frequency terminals 4T are arranged diagonally on the inner side of the peripheral wall 22 of the housing 2. This further increases the distance between the two high-frequency terminals 4T.

[0106] Two high-frequency terminals 4T are electrically connected to signal lines formed by a conductor pattern 170 on the circuit board 150. At least one of the six low-frequency terminals 4P is electrically connected to a power line formed by a conductor pattern 170 on the circuit board 150. Compared to the six low-frequency terminals 4P, the two high-frequency terminals 4T transmit signals at higher frequencies. The frequency of the signal transmitted by the two high-frequency terminals 4T is, for example, around 5 GHz to 50 GHz.

[0107] Additionally, at least one of the six low-frequency terminals 4P can also be electrically connected to the inner shield 3. Thus, at least one of the six low-frequency terminals 4P and the inner shield 3 are at the same potential. Specifically, the potential of at least one of the six low-frequency terminals 4P and the potential of the inner shield 3 are both ground potentials. At least one of the six low-frequency terminals 4P can be electrically connected to the inner shield 3, for example, via conductors 170 and 180 of the circuit board 150. Furthermore, at least one of the six low-frequency terminals 4P can also be electrically connected to the inner shield 3 without the aid of the circuit board 150.

[0108] (2.1.4.2) Shape

[0109] Each terminal 4 has the same shape. Each terminal 4 is formed, for example, by stamping and bending a metal sheet. Figure 11 As shown, each terminal 4 has a contact portion 41, a base portion 42, a connecting portion 43, a protrusion 44, a substrate connecting portion 45, and a contact portion 46.

[0110] The substrate connection portion 45 is electrically connected, for example, to the conductor 180 (solder) of the circuit board 150. That is, the substrate connection portion 45 is bonded to the circuit board 150 by a bonding means such as soldering. Thus, the circuit board 150 and the terminal 4 are mechanically and electrically connected. Furthermore, as... Figure 2 As shown, when viewed along the vertical direction Dud, the substrate connection portion 45 is surrounded by the outer shield 1. Furthermore, at least a portion of the substrate connection portion 45 and at least a portion of the outer shield 1 exist on a plane orthogonal to the vertical direction Dud.

[0111] The connecting portion 43 is formed in a U-shape that opens downwards (Dd). The connecting portion 43 connects the upper end of the base portion 42 and the upper end of the contact portion 41. The lower end of the base portion 42 is connected to the substrate connecting portion 45.

[0112] The protrusion 44 is formed in the shape of a letter U, opening upwards (Du). The protrusion 44 connects the lower end of the contact portion 41 and the contact portion 46. The contact portion 41 and the contact portion 46 are opposite to each other in the left-right direction (Dlr). In this embodiment, at least the connecting portion 43 and the protrusion 44 in the terminal 4 are elastic.

[0113] With terminal 4 held by housing 2, at least partially of contact portion 41 and contact portion 46 are exposed when viewed from above. Contact portion 41 and contact portion 46 contact corresponding terminals 8 among the plurality of terminals 8 (object-side terminals) of plug H1 (object-side connector) and are electrically connected to terminals 8 (see reference). Figure 12 Specifically, the contact portions 81 and 84 of terminal 8 are inserted between contact portions 41 and 46. At this time, under the elastic action of the protrusion 44, contact portions 41 and 46 are pressed by terminal 8.

[0114] Terminal 4 also has a force-feeling part 47. The force-feeling part 47 generates a locking sensation when terminal 4 comes into contact with terminal 8 (the object-side terminal). The force-feeling part 47 is a protrusion extending from the contact part 41. A locking sensation is generated when the force-feeling part 85 (protrusion) of terminal 8 passes over the force-feeling part 47. Specifically, as the force-feeling part 85 moves downward and passes over the force-feeling part 47, the magnitude of the force acting between terminal 4 and terminal 8 decreases. Therefore, the operator connecting terminal 4 and terminal 8 can feel this decrease in the magnitude of the force as a locking sensation. By feeling the locking sensation, the operator can understand the progress of the connection between socket S1 and plug H1. Furthermore, the connection between socket S1 and plug H1, and the connection between terminal 4 and terminal 8 thereafter, is not limited to being performed by human hand, but can also be performed mechanically.

[0115] When terminals 4 and 8 are connected, the contact portion 46 is inserted into the recess 840 of terminal 8. When transitioning from the connected state of terminals 4 and 8 to the unconnected state, a certain amount of force is required for the force-sensing portion 85 to move upward and pass over the force-sensing portion 47, and for the contact portion 46 to disengage from the recess 840. Thus, the combination of the force-sensing portion 85 and the force-sensing portion 47, and the combination of the contact portion 46 and the recess 840, respectively constitute a locking mechanism capable of maintaining the connection state between the socket S1 and the plug H1.

[0116] like Figure 3 As shown, the abutting portion 332 of the inner shield 3 and the contact portion 41 of at least one of the multiple terminals 4 are arranged in the front-rear direction Dfb.

[0117] (2.1.5) Circuit board on the socket side

[0118] The socket S1 is electrically connected to the conductor 180 (solder) of the circuit board 150. Figure 2 The diagram shows the area on the lower surface of the socket S1 where the conductor 180 is located, indicated by a dashed line. The conductor 180 is partially located on the lower surface of the outer shield 1 along the circumferential direction D10 of the outer shield 1. Here, conductors 180 are provided in multiple regions on the lower surface of the outer shield 1, spaced apart on the circumferential direction D10. However, it is also possible that conductors 180 are continuously provided on the lower surface of the outer shield 1, covering the entire circumference D10 of the outer shield 1. That is, it is also possible that the outer shield 1 is in continuous contact with the conductor 180 along the entire circumferential direction D10.

[0119] Furthermore, a portion of the conductor 180 is configured to have an outer shield 1 and each inner shield 3 mounted on it. Also, a portion of the conductor 180 is provided on the lower surface of each inner shield 3 along the length of the inner shield 3. Here, on the lower surface of each inner shield 3, multiple (3) regions are provided with conductors 180 spaced apart along the length of the inner shield 3. However, it is also possible that the conductors 180 are continuously provided on the lower surface of each inner shield 3 along the entire length of the inner shield 3. That is, it is also possible that the inner shield 3 is in continuous contact with the conductor 180 along its entire length.

[0120] A portion of conductor 180 is electrically connected to the outer shield 1 and each of the inner shields 3, and is also electrically connected to the conductor 170 of the circuit board 150, which has a ground potential. That is, the potentials of the outer shield 1 and each of the inner shields 3 are ground potentials. A large portion of the surface of the substrate 160 on the side connected to the socket S1 is preferably occupied by the conductor 170 with a ground potential. In other words, a so-called ground layer is preferably provided on the circuit board 150. This improves the shielding effect.

[0121] Additionally, a portion of conductor 180 is electrically connected to the substrate connection portion 45 of terminal 4. Terminal 4 is electrically connected to appropriate circuits via conductor 170 (wiring pattern) of circuit board 150. For example, a plurality of high-frequency terminals 4T are electrically connected to circuitry for processing signals. Additionally, for example, at least a portion of a plurality of low-frequency terminals 4P are electrically connected to wiring for transmitting signals at frequencies lower than those transmitted by high-frequency terminals 4T, or to power supply circuitry or grounding.

[0122] (2.1.6) Electrical closed loop of the socket

[0123] Figure 13 The configuration of the outer shield 1, multiple (two) inner shields 3 and multiple (eight) terminals 4 as viewed from below is schematically shown.

[0124] At least three electrical loops LO1, LO2, and LO3, as described below, are formed in socket S1. Each electrical loop LO1, LO2, and LO3 includes an outer shield 1, two inner shields 3, and at least one outer shield 1 and one or two inner shields 3 from imaginary paths W7, W8, W9, and W10. That is, each electrical loop LO1, LO2, and LO3 necessarily includes a path ending in the outer shield 1 and a path ending in one inner shield 3 or in each of the two inner shields 3, arbitrarily including at least one of the imaginary paths W7, W8, W9, and W10. The two imaginary paths W7 and W8 (or W9 and W10) connect the two top regions r1 of the outer shield 1 and the inner shield 3 with the shortest distance L1, respectively. Each electrical loop LO1, LO2, and LO3 surrounds at least one terminal 4. Each electrical closed loop LO1, LO2, and LO3 does not surround other electrical closed loops. Other electrical closed loops include the outer shield 1, the two inner shields 3, and at least one outer shield 1 and one or two inner shields 3 from the hypothetical paths W7, W8, W9, and W10. Electrical closed loop LO1 does not surround electrical closed loops LO2 and LO3, electrical closed loop LO2 does not surround electrical closed loops LO1 and LO3, and electrical closed loop LO3 does not surround electrical closed loops LO1 and LO2.

[0125] In this disclosure, when it is said that an electrical closed loop (hereinafter referred to as the first closed loop) surrounds other electrical closed loops (hereinafter referred to as the second closed loop), the portions of the first closed loop and the portions of the second closed loop may overlap.

[0126] The longest loop in the electrical closed loops LO1, LO2, and LO3 is shorter than the wavelength of the maximum frequency of the transmitted signal flowing to terminal 4. This reduces the likelihood of resonance in the transmitted signal. More specifically, the maximum frequency refers to the maximum frequency of the transmitted signal flowing to the high-frequency terminal 4T. In other words, in this embodiment, the maximum frequency is determined based on the specifications of the high-frequency terminal 4T.

[0127] The paths W2, W3, W4 of the outer shield 1, the inner shield 3, and the paths W7 and W8 constitute an electrical closed loop LO5. The paths W2, W1, W4 of the outer shield 1, the inner shield 3, and the paths W9 and W10 constitute an electrical closed loop LO6. Thus, two of the hypothetical paths W7 to W10, the outer shield 1, and the inner shield 3 constitute multiple electrical closed loops LO1, LO2, LO3, LO5, and LO6. These multiple electrical closed loops LO1, LO2, LO3, LO5, and LO6 pass through two of the hypothetical paths W7 to W10, the entirety of the outer shield 1 and the inner shield 3, including both the outer shield 1 and the inner shield 3, and surround the terminal 4. Among the multiple electrical closed loops LO1, LO2, LO3, LO5, and LO6, electrical closed loop LO5 surrounds electrical closed loops LO2 and LO3 except for itself, and electrical closed loop LO6 surrounds electrical closed loops LO1 and LO2 except for itself. One or more specific electrical loops LO1, LO2, LO3, LO5, LO6 do not surround any other electrical loop among the multiple electrical loops LO1, LO2, LO3, LO5, LO6 besides themselves. The longest loop length among the more than one specific electrical loops LO1, LO2, LO3 is shorter than the wavelength of the maximum frequency of the transmitted signal flowing to terminal 4.

[0128] Furthermore, when the connector has only one inner shield, a total of two hypothetical paths are formed at its two ends. The two hypothetical paths, the outer shield, and the inner shield constitute multiple electrical closed loops.

[0129] In connectors as described in Japanese Patent Application Publication No. 2013-182808, the transmitted signal transmitted by the connector sometimes resonates.

[0130] In contrast, the connector of this embodiment can reduce the possibility of resonance of the transmitted signal flowing to terminal 4.

[0131] Furthermore, if not limited to the plane orthogonal to the vertical direction Dud, electrical loops other than electrical loops LO1, LO2, and LO3 can also be formed in socket S1. However, compared with electrical loops LO1, LO2, and LO3, their loop lengths are shorter, so they are not used here.

[0132] Next, the paths W1 to W10 that constitute the electrical closed loop LO1, LO2, and LO3 will be explained.

[0133] Two inner shielding members 3 are arranged in a rear-to-rear arrangement around the socket S1. On the left side of the outer shielding member 1, there is a region r2 opposite to the top left region r1 of the front inner shielding member 3 and a region r3 opposite to the top left region r1 of the rear inner shielding member 3. On the right side of the outer shielding member 1, there is a region r4 opposite to the top right region r1 of the front inner shielding member 3 and a region r5 opposite to the top right region r1 of the rear inner shielding member 3.

[0134] Path W1 is contained in the front region of the outer shield 1, connecting regions r4 and r2 along the outer shield 1. Path W2 connects regions r2 and r3 along the left side of the outer shield 1.

[0135] Path W3 is contained in the rear region of the outer shield 1, connecting regions r3 and r5 along the outer shield 1. Path W4 connects regions r5 and r4 along the right side of the outer shield 1.

[0136] Path W5 connects the two top regions r1 of the upper inner shield 3. Path W6 connects the two top regions r1 of the lower inner shield 3.

[0137] Path W7 connects region r2 of the outer shield 1 and the top left region r1 of the front inner shield 3 with the shortest distance L1. Path W8 connects region r4 of the outer shield 1 and the top right region r1 of the front inner shield 3 with the shortest distance L1.

[0138] Path W9 connects region r3 of the outer shield 1 and the top left region r1 of the inner shield 3 on the rear side with the shortest distance L1. Path W10 connects region r5 of the outer shield 1 and the top right region r1 of the inner shield 3 on the rear side with the shortest distance L1.

[0139] Electrical closed loop LO1 is formed by paths W1, W7, W5, and W8. Electrical closed loop LO2 is formed by paths W2, W9, W6, W10, W4, W8, W5, and W7. Electrical closed loop LO3 is formed by paths W3, W10, W6, and W9.

[0140] As described above, in this disclosure, when it is said that an electrical closed loop (first closed loop) surrounds other electrical closed loops (second closed loop), the portions of the first closed loop and the portions of the second closed loop may overlap. For example, in Figure 13 In the first closed loop formed by paths W4, W1, W2, W9, W6, and W10, and the electrical closed loop LO1, which is the second closed loop, overlap on path W1, and the first closed loop surrounds the second closed loop.

[0141] In this embodiment, the loop length of electrical closed loop LO2 is the longest among electrical closed loops LO1, LO2, and LO3. An example of the longest loop length is approximately 6 to 7 mm.

[0142] Assume the maximum frequency fMAX of the transmitted signal flowing to terminal 4 is set to 10 GHz (10 10 If the maximum frequency of the transmitted signal is fMAX (Hz), then the wavelength λ is λ = 3 × 10⁻⁶. 8 / fMAX=0.03[m]=30[mm]. When the longest ring length is 6~7[mm], this longest ring length satisfies the condition that it is shorter than the wavelength λ of the maximum frequency fMAX.

[0143] Furthermore, the outer shield 1 forms an electrical closed loop LO4 surrounding the terminal 4 without the aid of the inner shield 3. The electrical closed loop LO4 is formed by paths W1, W2, W3, and W4. That is, the continuous cylindrical portion 10 in the circumferential direction D10 of the outer shield 1 (see reference...) Figure 4 This forms an electrical closed loop LO4. Electrical closed loop LO4 surrounds electrical closed loops LO1, LO2, and LO3.

[0144] Here, since the outer shield 1 is formed without gaps in the circumferential direction D10 of the cylindrical portion 10, the electrical closed loop LO4 is constituted as a single unit. However, the outer shield 1 may also constitute the electrical closed loop LO4 together with the conductors 170 and / or 180 of the circuit board 150. That is, even if the outer shield 1 has gaps, the path connecting the two ends of the gap may be formed by the conductors 170 and / or 180, and the electrical closed loop LO4 may include this path. Alternatively, the conductors 170 and / or 180 may not be included in the structure of the socket S1.

[0145] (2.2) Structure of the plug

[0146] Next, the structure of the plug H1 in this embodiment will be described. For structures in the plug H1 that are identical to those in the socket S1, descriptions will be omitted as appropriate.

[0147] The plug H1 is doubly symmetrical about the axis passing through its center and along the vertical direction Dud. For example... Figure 5 As shown, the plug H1 has an outer shield 5, a housing 6, multiple (two) inner shields 7, and multiple (eight) terminals 8. Each inner shield 7 of the outer shield 5 and the multiple inner shields 7 is an electrostatic shield. The outer shield 5 surrounds the multiple terminals 8. That is, the outer shield 5 is disposed on the outside of the multiple terminals 8. The multiple inner shields 7 are disposed on the inside of the outer shield 5. Additionally, the multiple inner shields 7 are disposed on the inside of the housing 6.

[0148] Circuit board 550 (reference) Figure 9 The circuit board 550 is mechanically and electrically connected to the plug H1. The circuit board 550 has a substrate 560 (see reference). Figure 9 ) and conductors 570, 580 (refer to) Figure 9 It has the same structure as the substrate 160 and conductors 170 and 180 of the circuit board 150 connected to the socket S1. The conductor 570, for example, is provided on approximately the entire surface of the substrate 560 on the side where the plug H1 is connected. Additionally, in Figure 6 In the diagram, a two-dot dashed line is used to indicate the area where conductor 580 (solder) is located.

[0149] (2.2.1) Plug housing

[0150] The housing 6 is a resin molded body. The housing 6 is electrically insulating. The housing 6 has a bottom wall 61 and a peripheral wall 62. The bottom wall 61 is formed as a rectangle that, when viewed from above, is longer in the front-rear direction Dfb than in the left-right direction Dlr. The peripheral wall 62 protrudes downwards Dd from the outer periphery of one side (lower surface) of the bottom wall 61 in the thickness direction. The left and right sides of the housing 6 have multiple (in) through-beams penetrating the bottom wall 61 and the peripheral wall 62 in the vertical direction Dud. Figure 5 (Two notches 601 on the left side and two on the right side). Multiple notches 601 are provided at positions opposite to the substrate connection portion 83 of the terminal 8 when viewed vertically in the Dud direction (see reference). Figure 6 ).

[0151] like Figure 7 As shown, the housing 6 also has two wall portions 65. Each wall portion 65 protrudes downwards Dd from the bottom wall 61. The shape of the wall portion 65 is a cuboid with its lower surface curved in a cylindrical shape (see reference). Figure 10 The front and rear ends of the wall portion 65 are connected to the peripheral wall 62. When viewed along the vertical direction Dud, the wall portion 65 is longer in the front-rear direction Dfb than in the left-right direction Dlr. That is, the wall portion 65 has thickness along the left-right direction Dlr. The two wall portions 65 are arranged in the left-right direction Dlr.

[0152] Each wall portion 65 has multiple (two) receiving portions 68. Each receiving portion 68 receives an extension 72 of the inner shielding member 7. Each receiving portion 68 is a through hole provided in the wall portion 65. The receiving portion 68 penetrates the wall portion 65 in the vertical direction Dud. The receiving portion 68 also penetrates the bottom wall 61 in the vertical direction Dud. Furthermore, when viewed along the vertical direction Dud, the receiving portion 68 provided in the wall portion 65 is a recessed portion from the side of the wall portion 65 (the surface intersecting the horizontal direction Dur).

[0153] In addition, each wall portion 65 has a plurality of (4) terminal holding portions 69. Each terminal holding portion 69 holds one terminal 8. The plurality of terminal holding portions 69 are recesses provided in the wall portion 65.

[0154] Multiple terminals 8 are embedded in the housing 6. In this embodiment, eight terminals 8 are fixed to the housing 6. The eight terminals 8 of the plug H1 correspond one-to-one with the eight terminals 4 of the socket S1. Each terminal 8 is positioned to connect with its corresponding terminal 4.

[0155] like Figure 5 , Figure 6 As shown, the bottom wall 61 has multiple (two) storage slots 613. Each storage slot 613 is a groove provided on the upper surface of the bottom wall 61. The storage slot 613 is longer in the left-right direction Dlr than in the front-back direction Dfb. The storage slot 613 houses the base 71 of the inner shielding member 7.

[0156] like Figure 7 As shown, the peripheral wall 62 has a plurality of (two) insertion portions 623. The plurality of (two) insertion portions 623 are recesses provided on the bottom surface (lower surface) of the peripheral wall 62. As will be described later, shielding protrusions 54, which are part of the outer shielding member 5, are inserted into the plurality of (two) insertion portions 623 respectively.

[0157] (2.2.2) External shielding of the plug

[0158] The outer shield 5 surrounds multiple terminals 8 and multiple inner shields 7. The outer shield 5 comprises a material such as metal as the main material or a plating layer forming the surface. Here, as an example, the outer shield 5 is formed primarily of metal. Figure 5 , Figure 8 As shown, the outer shield 5 has an outer peripheral wall 51, a plurality of (4) top walls 52, a plurality of (2) shield protrusions 54 and a bottom wall 55.

[0159] The outer peripheral wall 51 has a square cylindrical shape with a rectangular cross-section. The outer peripheral wall 51 includes two outer peripheral walls 511 and two outer peripheral walls 512. The two outer peripheral walls 511 are portions of the outer peripheral wall 51 that extend approximately parallel to the front-rear direction Dfb and are opposite each other in the left-right direction Dlr. The two outer peripheral walls 512 are portions of the outer peripheral wall 51 that extend approximately parallel to the left-right direction Dlr and are opposite each other in the front-rear direction Dfb. The two outer peripheral walls 512 connect the ends of the two outer peripheral walls 511 to each other.

[0160] The outer shield 5 also has a plurality of protrusions 56 protruding from the outer peripheral wall 51. The plurality of protrusions 56 function as contact portions that contact the outer shield 1 of the target-side connector (here, socket S1). The outer peripheral wall 51, the top wall 52, and the plurality of protrusions 56 form a cylindrical portion 50 with openings at both ends in the vertical direction Dud. That is, the cylindrical portion 50 includes the outer peripheral wall 51, the top wall 52, and the plurality of protrusions 56. The outer peripheral surface 501 of the cylindrical portion 50 includes a portion of the outer peripheral surface of the outer peripheral wall 51 and the surfaces of the plurality of protrusions 56. The cylindrical portion 50 surrounds the hollow portion 50S.

[0161] The outer shield 5 of the connector (here, plug H1) has a side surface (outer peripheral surface 501) extending in the vertical direction Dud. This side surface (outer peripheral surface 501) has a convex structure. That is, the structure including multiple protrusions 56 corresponds to a convex structure. The outer shield 5 of the connector (here, plug H1) contacts the outer shield 1 of the target connector (here, socket S1) at the convex structure (multiple protrusions 56). More specifically, the multiple protrusions 56 contact the inner peripheral surface 103 of the cylindrical portion 10 of the outer shield 1 (see reference). Figure 10 ).

[0162] Compared to the case where the outer peripheral surface 501 is planar without multiple protrusions 56, even if there are slight deviations in the dimensions of the outer shielding members 1 and 5, the outer shielding member 1 can be pressed into the outer shielding member 5. Therefore, the possibility of poor contact such as the following can be reduced: the outer shielding members 1 and 5 are in contact with each other in one of the left-right direction Dlr or the front-back direction Dfb, and separate in the other direction of the left-right direction Dlr or the other direction of the front-back direction Dfb.

[0163] Each of the two outer peripheral walls 511 has three protrusions 56. Each of the two outer peripheral walls 512 has one protrusion 56. The plurality of protrusions 56 surround the hollow portion 50S in the circumferential direction D50 (see reference). Figure 8 The protrusions 56 are spaced apart. The maximum creepage distances L2 and L3 between the protrusions 56 are less than 1 / 4 of the wavelength λ of the maximum frequency of the transmitted signal flowing to the terminal 8. This reduces the possibility of noise leakage from the area between the protrusions 56 (the area in the outer shield 5 that is not electrically connected to the outer shield 1). Here, the creepage distance L2 between the protrusions 56 on the outer peripheral wall 511 and the protrusions 56 on the outer peripheral wall 512 is greater than the creepage distance L3 between the protrusions 56 on the outer peripheral wall 511. That is, the maximum creepage distance between the protrusions 56 is the creepage distance L2. More specifically, the maximum frequency is the maximum frequency of the transmitted signal flowing to the high-frequency terminal 8T among the multiple terminals 8. That is, in this embodiment, the maximum frequency is determined according to the specifications of the high-frequency terminal 8T.

[0164] Each of the multiple (4) top walls 52 is L-shaped when viewed in the vertical direction Dud. The multiple (4) top walls 52 are connected to the lower ends of the four corners of the outer peripheral wall 51 and extend toward the inner side of the outer peripheral wall 51 when viewed in the vertical direction Dud.

[0165] The bottom wall 55 is rectangular when viewed along the vertical direction Dud. The bottom wall 55 is connected to the upper end of the outer peripheral wall 51 and extends outward from the outer peripheral wall 51 when viewed along the vertical direction Dud. The lower surface of the bottom wall 55 is formed to be parallel to the front-back direction Dfb and the left-right direction Dlr, and parallel to a plane perpendicular to the vertical direction Dud.

[0166] The inner peripheral surface of the outer peripheral wall 51 corresponds to the inner peripheral surface 503 of the cylindrical portion 50. Additionally, the outer shield 5 has a top surface 502. The top surface 502 is located at one of the two ends of the cylindrical portion 50 in the vertical direction Dud, becoming the target connector side (lower end) when transitioning from a non-connected state to a connected state between the connector (plug H1) and the target connector (socket S1). The top surface 502 is provided along the inner edge of the cylindrical portion 50. Here, the upper surface of the top wall 52 corresponds to the top surface 502. Furthermore, the inner edge of the top surface 502 corresponds to a portion of the inner edge of the cylindrical portion 50 at its lower end.

[0167] The boundary portion b3 between the top surface 502 and the outer peripheral surface 501 is an arc-shaped surface when viewed from the front-rear direction Dfb (see reference). Figure 9 Furthermore, the top surface 502 is defined here as the region on the outer surface of the cylindrical portion 50 where the acute angle formed with respect to the vertical direction Dud is 0 degrees or more and less than 45 degrees. The outer surface with the acute angle of 45 degrees or more is defined as the outer peripheral surface 501. The boundary portion b3 has a predetermined length along the circumferential direction D50 of the cylindrical portion 50.

[0168] Multiple (two) shielding protrusions 54 are provided, one for each of two of the multiple (four) top walls 52. Each shielding protrusion 54 protrudes upward from the corresponding top wall 52. The multiple (two) shielding protrusions 54 correspond to the multiple (two) insertion portions 623 (see reference) provided in the housing 6. Figure 7 A one-to-one correspondence. Each shielding protrusion 54 is inserted into the corresponding insertion part 623.

[0169] The outer shield 5 is fixed to the housing 6 by pressing it in. That is, the outer shield 5 is held by the housing 6 by being pressed in one direction (upward). At this time, the plurality of top walls 52 of the outer shield 5 cover at least a portion of the peripheral wall 62 of the housing 6. In addition, at this time, each shield protrusion 54 is inserted into the corresponding insertion part 623.

[0170] The outer shield 5 is formed seamlessly over its entire surface. In this embodiment, at least the outer peripheral surface 501 and the inner peripheral surface 503 of the outer shield 5 are seamless (i.e., without seams and cracks) over the entire circumferential direction D50 of the cylindrical portion 50.

[0171] like Figure 8 As shown, the outer peripheral surface 501 includes an outer surface 5110 (including the surface of the outer peripheral wall 511 and the surface of the protrusion 56) corresponding to the two outer peripheral walls 511 respectively, and an outer surface 5120 (including the surface of the outer peripheral wall 512 and the surface of the protrusion 56) corresponding to the two outer peripheral walls 512 respectively. The outer surfaces 5110 and 5120 are seamless. Furthermore, the two surfaces with different normal directions, namely the outer surfaces 5110 and 5120, are seamlessly connected. Thus, the outer peripheral surface 501 is seamless along the entire circumferential direction D50 of the cylindrical portion 50.

[0172] In addition, such as Figure 8 As shown, the inner circumferential surface 503 includes the inner surfaces 5111 of each of the two outer circumferential walls 511 and the inner surfaces 5121 of each of the two outer circumferential walls 512. The inner surfaces 5111 and 5121 are seamless. Furthermore, the two surfaces with different normal directions, namely the inner surfaces 5111 and 5121, are seamlessly connected. Thus, the inner circumferential surface 503 is seamless along the entire circumferential direction D50 of the cylindrical portion 50.

[0173] Furthermore, the boundary portion b3 between the outer peripheral surface 501 and the top surface 502 is seamless. For example, in Figure 8 At the upper right position of the paper (corner of the outer shield 5), the three surfaces with different normal directions, namely the outer surface 5110, the outer surface 5120 and the top surface 502, are seamlessly connected.

[0174] (2.2.3) Inner shielding of the plug

[0175] In this embodiment, the two inner shielding members 7 have the same shape. The inner shielding member 7 comprises metal as the main material or a material constituting a surface plating, etc. Here, as an example, the inner shielding member 7 is formed primarily of metal. Figure 9 As shown, the inner shield 7 has a base 71 and a plurality of (two) extensions 72.

[0176] The base 71 has a length along the left-right direction Dlr. The base 71 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of the base 71, the base 71 is longer in the left-right direction Dlr than in the up-down direction Dud. The base 71 is housed in a receiving groove 613 provided on the bottom wall 61 of the housing 6.

[0177] Multiple extensions 72 protrude downward from the base 71. That is, the multiple extensions 72 protrude along the vertical direction Dud, facing the direction that becomes the target connector side when transitioning from a non-connected state to a connected state between the connector (plug H1) and the target connector (socket S1). Each extension 72 is rectangular in shape. When viewed along the thickness direction (front-back direction Dfb) of each extension 72, each extension 72 is longer in the vertical direction Dud than in the horizontal direction Dlr. Alternatively, the thickness direction of each extension 72 could also be the horizontal direction Dlr.

[0178] The extension 72 includes an abutment portion 720 (contact surface) that contacts the inner shield 3 of the object-side connector (receptacle S1). The abutment portion 720 is provided on a surface (either left or right) of the extension 72 along its length. The abutment portions 720 of the two extensions 72 face opposite directions to each other (right direction Dr and left direction Dl).

[0179] The plug H1 has two extensions 72 on each of the two inner shields 7. That is, the plug H1 has a total of four extensions 72. Four storage portions 68 are provided in the housing 6 (see reference). Figure 7 Each of the four extensions 72 corresponds one-to-one. Each extension 72 is housed in its corresponding storage section 68.

[0180] The inner shielding member 7 is fixed to the housing 6 by pressing it in. That is, the inner shielding member 7 is held by the housing 6 by being pressed in one direction (downward). At this time, each extension 72 is housed in the corresponding housing portion 68. Here, the housing space of each of the two extensions 72 in the shielding member holding portion (housing portion 68) can also be larger than each extension 72 of the two extensions 72.

[0181] like Figure 9 As shown, the base 71 of the inner shield 7 is located at the upper end of the plug H1. Here, the outer shield 5 has an end e5 and an end e6. End e5 is the end (lower end) that becomes the side of the target connector when transitioning from a non-connected state to a connected state between the connector (plug H1) and the target connector (socket S1). End e6 is the end (upper end) on the opposite side of end e5. Furthermore, end e6 is defined as a region along the entire circumference D50 surrounding the hollow portion 50S of the bottom wall 55 of the outer shield 5. In the region including end e6, the outer shield 5 is opposite to the two top regions r7 of the inner shield 7.

[0182] The outer shield 5, in the region including end e6, is positioned opposite at least one of the two top regions r7 with a gap g7 between them. For example... Figure 9As shown, conductors 570 and 580 of the circuit board 550 are electrically connected to the outer shield 5. Furthermore, conductors 570 and 580 are configured to support the ends e6 of the outer shield 5 on the two top regions r7 of the inner shield 7, respectively. In other words, the outer shield 5 is electrically connected to the inner shield 7 via conductors 570 and 580. On the other hand, in the absence of the circuit board 550, the outer shield 5 is electrically insulated from at least one of the two top regions r7 (both in this embodiment) through a gap g7. The shortest distance L7 between the outer shield 5 in the gap g7 and at least one of the two top regions r7 is 0.01 mm or more and 0.1 mm or less.

[0183] The inner shield 7 has an end e7 and an end e8. End e7 is the end (lower end) that becomes the counterpart connector side when transitioning from a non-connected state to a connected state between the connector (plug H1) and the counterpart connector (socket S1). End e8 is the end (upper end) on the opposite side of end e7. The inner shield 7 has a connection surface 710 (upper surface) at end e8 that is electrically connected to the circuit board 550. The connection surface 710 is planar and continuous across the two top regions r7. More specifically, the connection surface 710 is a rectangular plane that connects the two top regions r7.

[0184] (2.2.4) Plug terminals

[0185] like Figure 6 , Figure 7 As shown, the plurality of (8) terminals 8 includes a plurality of (6) low-frequency terminals 8P and a plurality of (2) high-frequency terminals 8T. The configuration of the plurality of terminals 8 is the same as the configuration of the plurality of terminals 4 of the socket S1. That is, the content described in "(2.1.4.1) Configuration" also applies to the plurality of terminals 8.

[0186] Each terminal 8 has the same shape. Each terminal 8 is formed, for example, by stamping and bending a metal sheet. Figure 11 As shown, each terminal 8 has a contact portion 81, a winding sheet 82, a substrate connection portion 83, and a contact portion 84.

[0187] The substrate connection portion 83 is electrically connected, for example, to the conductor 580 (solder) of the circuit board 550. That is, the substrate connection portion 83 is bonded to the circuit board 550 by a bonding means such as soldering. Thus, the circuit board 550 and the terminal 8 are mechanically and electrically connected. Furthermore, as... Figure 6 As shown, when viewed along the vertical direction Dud, the substrate connection portion 83 is surrounded by the outer shield 5. Furthermore, at least a portion of the substrate connection portion 83 and at least a portion of the outer shield 5 are present on a plane orthogonal to the vertical direction Dud.

[0188] Contact portions 81 and 84 have a length in the vertical direction Du. Contact portion 81 is the portion that contacts contact portion 41 of terminal 4 of socket S1, and contact portion 84 is the portion that contacts contact portion 46 of terminal 4 of socket S1. The winding tab 82 is formed in an upward-opening U-shape. The winding tab 82 connects the lower end of contact portion 81 and the lower end of contact portion 84. The substrate connecting portion 83 is a portion that protrudes from the upper end of contact portion 81.

[0189] With terminal 8 held by housing 6, at least partially of contact portion 81 and contact portion 84 are exposed when viewed from below. Contact portion 81 and contact portion 84 contact corresponding terminals 4 among the plurality of terminals 4 (object-side terminals) of socket S1 (object-side connector) and are electrically connected to terminals 4 (see reference). Figure 12 ).

[0190] Terminal 8 also has a force-feeling part 85. The force-feeling part 85 generates a locking sensation when terminal 8 comes into contact with terminal 4 (the object-side terminal). The force-feeling part 85 is a protrusion that protrudes from the contact part 81. A locking sensation is generated when the force-feeling part 85 (protrusion) passes over the force-feeling part 47 of terminal 4.

[0191] The contact portion 84 has a recess 840 on the contact surface that contacts the contact portion 46. That is, the contact portion 46 is inserted into the recess 840. Here, the contact portion 46 contacts the side surface of the recess 840.

[0192] like Figure 7 As shown, the abutting portion 720 of the inner shield 7 and the contact portion 81 of at least one of the plurality of terminals 8 are arranged in the front-rear direction Dfb.

[0193] (2.2.5) Circuit board on the plug side

[0194] Plug H1 is electrically connected to conductor 580 (solder) of circuit board 550. Figure 6 The area on the upper surface of plug H1 with conductor 580 is shown by a dashed line. The configuration and electrical connection of conductors 570 and 580, outer shield 5, multiple inner shields 7, and multiple terminals 8 of circuit board 550 are the same as those of conductors 170 and 180, outer shield 1, multiple inner shields 3, and multiple terminals 4 of circuit board 150 corresponding to socket S1.

[0195] (2.2.6) Electrical closed loop of the plug

[0196] The configuration of the outer shield 5, multiple (two) inner shields 7, and multiple (eight) terminals 8 of plug H1 is consistent with... Figure 13The outer shield 1, multiple (two) inner shields 3, and multiple (eight) terminals 4 of the socket S1 shown are configured identically. Therefore, in the plug H1, similarly to the socket S1, at least multiple (three) electrical closed loops LO1, LO2, and LO3 are formed. The detailed description of the electrical closed loops LO1, LO2, and LO3 of the plug H1 is the same as the detailed description of the electrical closed loops LO1, LO2, and LO3 of the socket S1. Furthermore, the outer shield 5, like the outer shield 1, forms an electrical closed loop LO4 surrounding the terminals 8 without the aid of the inner shield 7.

[0197] Here, since the outer shield 5 is formed without gaps in the circumferential direction D50 of the cylindrical portion 50, the electrical closed loop LO4 is constituted as a single unit. However, the outer shield 5 may also constitute the electrical closed loop LO4 together with the conductors 570 and / or 580 of the circuit board 550. That is, even if the outer shield 5 has gaps, the path connecting the two ends of the gap may be formed by the conductors 570 and / or 580, and the electrical closed loop LO4 may include this path. Alternatively, the conductors 570 and / or 580 may not be included in the structure of the plug H1.

[0198] (3) Assembly process

[0199] Next, refer to Figures 9-12 Here is an example illustrating the process of connecting the socket S1 and the plug H1 and assembling the connector device 100.

[0200] Circuit board 150 is mechanically and electrically connected to socket S1. Circuit board 550 is mechanically and electrically connected to plug H1. In this state, as... Figure 9 , Figure 11 As shown, the socket S1 is positioned below the plug H1. Then, at least one of the actions—moving the socket S1 upwards and moving the plug H1 downwards—is performed. Thus, as... Figure 10 , Figure 12 As shown, socket S1 and plug H1 are mechanically connected. Additionally, as... Figure 10 As shown, the inner shield 3 of socket S1 and the inner shield 7 of plug H1 are in contact and electrically connected. Additionally, as... Figure 12 As shown, multiple terminals 4 of socket S1 and multiple terminals 8 of plug H1 are in contact and electrically connected. Additionally, as... Figure 10 , Figure 12 As shown, the outer shield 1 of socket S1 and the outer shield 5 of plug H1 are in contact and electrically connected. Additionally, as... Figure 10 As shown, two walls 65 of the housing 6 of the socket S1 are inserted between walls 25 and 26 of the housing 2 and between walls 26 and 27 of the socket S1.

[0201] Here, when transitioning from the non-connected state to the connected state of the socket S1 and plug H1 (connector and object-side connector), the structures of the socket S1 and plug H1 come into contact with each other in the order described below.

[0202] First, the socket S1 and the plug H1 come into contact with each other at the outer shields 1 and 5. That is, the area near the upper end of the inner peripheral surface 103 of the cylindrical portion 10 of the outer shield 1 comes into contact with the area near the lower end of the outer peripheral surface 501 of the cylindrical portion 50 of the outer shield 5.

[0203] Next, the socket S1 and the plug H1 come into contact with each other at terminals 4 and 8. That is, at least one of the actions of contact 41 and contact 81 coming into contact with each other and contact 46 and contact 84 coming into contact with each other is completed.

[0204] Next, the socket S1 and the plug H1 come into contact with each other at the inner shields 3 and 7. That is, the abutting part 332 of the inner shield 3 and the abutting part 720 of the inner shield 7 come into contact with each other.

[0205] Next, the force-feeding part 47 (or 85) of the connector (socket S1 or plug H1) comes into contact with the target-side terminal (terminal 8 or 4). That is, at least one of the actions of the force-feeding part 47 contacting the contact part 81 of terminal 8 and the action of the force-feeding part 85 contacting the contact part 41 of terminal 4 is completed. Furthermore, a locking sensation is generated by the force-feeding parts 47 and 85.

[0206] Next, the outer shield 5 of the connector (here, plug H1) contacts the outer shield 1 of the target connector (here, socket S1) at the convex structure (multiple protrusions 56) (also called the contact portion). That is, the multiple protrusions 56 contact the inner circumferential surface 103 of the cylindrical portion 10 of the outer shield 1 (see reference). Figure 10 More specifically, firstly, the plurality of protrusions 56 contact the area near the upper end of the inner peripheral surface 103. Then, under the contact pressure between the plurality of protrusions 56 and the inner peripheral surface 103, while the outer shield 1 elastically deforms in a manner that the inner peripheral wall 13 of the outer shield 1 faces outward (towards the outer peripheral wall 11), the plurality of protrusions 56 further move downward. Finally, as... Figure 10 As shown, multiple protrusions 56 contact the region Dud along the vertical direction in the inner circumferential surface 103. Based on the above, the connection between the socket S1 and the plug H1 is completed.

[0207] In this way, a locking sensation is generated at terminals 4 and 8 before the contact pressure and friction between the outer shielding members 1 and 5 increase due to the contact of the multiple protrusions 56 with the outer shielding member 1. Therefore, compared to the case where a locking sensation is generated after the multiple protrusions 56 contact the outer shielding member 1, the operator can more easily feel the locking sensation. In other words, the situation where the locking sensation is not easily felt due to friction can be suppressed. In addition, the positional relationship of the outer shielding members 1 and 5, which are fixed by contact with the outer shielding member 1 through the multiple protrusions 56, will not change in subsequent processes, thus improving the positioning accuracy. As a result, the contact area between the outer shielding members 1 and 5 can be ensured.

[0208] (4) Noise Level

[0209] Figure 14 The solid line represents the analytical result of the radiated noise of the connector device 100 in the embodiment. Figure 14 The dashed line represents the analytical results of the radiated noise of the connector device in the comparative example. The horizontal axis represents frequency (in [GHz]), and the vertical axis represents noise level (in [dBμV / m]).

[0210] In the comparative example connector device, the outer shields 1 and 5 differ from the connector device 100 of the embodiment in that they are formed by bending a metal plate; otherwise, their structures are the same as those of the connector device 100 of the embodiment. Therefore, in the comparative example connector device, seams or cracks exist on the outer and inner circumferential surfaces of the outer shields 1 and 5, for example, the cylindrical portion 10 (50), along the circumferential direction D10 (D50) of the cylindrical portion 10 (50). In contrast, in the connector device 100 of the embodiment, each outer shield 1 and 5 is formed by deep drawing of metal. Therefore, the outer and inner circumferential surfaces of the cylindrical portion 10 (50) of each outer shield 1 and 5 are seamlessly formed (that is, without seams or cracks) along the entire circumference D10 (D50) of the cylindrical portion 10 (50).

[0211] like Figure 14 As shown, for each frequency, the connector device 100 of the embodiment reduces the noise level compared to the connector device of the comparative example. That is, compared to the comparative example, in the embodiment, since the seams of the outer shields 1 and 5 are removed, it is possible to not only suppress the influence of resonance but also reduce the noise radiated from the seams.

[0212] (Variation Example 1)

[0213] The following uses Figures 15-18 The socket S2 and plug H2 of Modified Example 1 will be described below. For structures identical to those in the embodiment, the same reference numerals are used and descriptions are omitted. Additionally, in Figure 15 , Figure 17 In the diagram, two dashed lines are used to indicate the areas with conductors 180 and 580 (solder).

[0214] like Figure 15 , Figure 16 As shown, the socket S2 has only one inner shield 3. Additionally, the socket S2 has only two terminals 4. Correspondingly, the shapes of the outer shield 1A and the housing 2A differ from the shapes of the outer shield 1 and the housing 2 in the embodiment. This will be explained in more detail below.

[0215] The approximate shape of housing 2A is the shape of housing 2 in embodiment omitting the area where six low-frequency terminals 4P are provided. The approximate shape of outer shield 1A is the shape of outer shield 1 in embodiment omitting the area where six low-frequency terminals 4P are provided.

[0216] The wall portions 25, 26 and 27 of the housing 2A each have a receiving portion 28. The three receiving portions 28 house the three extensions 32 of the inner shielding member 3.

[0217] Additionally, wall portion 25 and wall portion 27 each have one terminal holding portion 29. Wall portion 26 has two terminal holding portions 29. One of the two terminals 4 is held in the terminal holding portion 29 of wall portion 25 and one of the terminal holding portions 29 of wall portion 26. The other of the two terminals 4 is held in the terminal holding portion 29 of wall portion 27 and the other of the terminal holding portions 29 of wall portion 26.

[0218] Here, the two terminals 4 are high-frequency terminals 4T, but it is not limited to this. Alternatively, at least one of the two terminals 4 can be a low-frequency terminal 4P.

[0219] Two high-frequency terminals 4T are disposed on both sides (front and rear) separated by an inner shield 3. Therefore, similar to the embodiment, the possibility of noise transmission between the two high-frequency terminals 4T can be reduced.

[0220] like Figure 17 , Figure 18 As shown, plug H2 has only one inner shield 7. Additionally, plug H2 has only two terminals 8. Correspondingly, the shapes of the outer shield 5A and housing 6A differ from those of the outer shield 5 and housing 6 in the embodiment. This will be explained in more detail below.

[0221] The approximate shape of housing 6A is the shape of housing 6 in embodiment omitting the area where six low-frequency terminals 8P are provided. The approximate shape of outer shield 5A is the shape of outer shield 5 in embodiment omitting the area where six low-frequency terminals 8P are provided.

[0222] Each of the two wall portions 65 of the housing 6 has a receiving portion 68. The two receiving portions 68 receive the two extensions 72 of the inner shield 7.

[0223] In addition, each of the two wall portions 65 has a terminal holding portion 69. A terminal 8 is held in each terminal holding portion 69.

[0224] Here, the two terminals 8 are high-frequency terminals 8T, but it is not limited to this. Alternatively, at least one of the two terminals 8 may be a low-frequency terminal 8P.

[0225] Two high-frequency terminals 8T are disposed on both sides (front and rear) separated by an inner shield 7. Therefore, similar to the embodiment, the possibility of noise transmission between the two high-frequency terminals 8T can be reduced.

[0226] (Variation Example 2)

[0227] The following uses Figure 19 , Figure 20 The socket S1 and plug H1 of Modified Example 2 will be described below. For structures identical to those in the embodiment, the same reference numerals are used and descriptions are omitted. Furthermore, in Figure 19 , Figure 20 The diagram only shows two high-frequency terminals 4T and two high-frequency terminals 8T from socket S1 and plug H1.

[0228] In this modified example 2, the low-frequency terminal 4P and the high-frequency terminal 4T in the socket S1 have different shapes. Additionally, the low-frequency terminal 8P and the high-frequency terminal 8T in the plug H1 have different shapes.

[0229] That is, in this modified example 2, the socket S1 has multiple terminals 4. The plug H1 has multiple terminals 8. The multiple terminals 4 (or 8) include a first terminal (low-frequency terminal 4P or 8P) and a second terminal (high-frequency terminal 4T or 8T). The shape of the second terminal is different from that of the first terminal. An inner shield 3 (or 7) is disposed between the first terminal and the second terminal (see reference). Figure 13 ).

[0230] As an example, the low-frequency terminal 4P has the same shape as the low-frequency terminal 4P in the embodiment. Additionally, as an example, the low-frequency terminal 8P has the same shape as the low-frequency terminal 8P in the embodiment.

[0231] On the other hand, as an example, such as Figure 19 As shown, the high-frequency terminal 4T of this modified example 2 has two contact portions 41, a base portion 42, and a substrate connection portion 45. The high-frequency terminal 4T is formed, for example, by punching and bending a metal plate.

[0232] The base 42 is formed in the shape of a letter U, opening upwards (Du). The substrate connecting portion 45 is connected to the lower end of the base 42. One contact portion 41 protrudes from the left end of the base 42 in the forward-backward direction (Dfb), and the other contact portion 41 protrudes from the right end of the base 42 in the forward-backward direction (Dfb).

[0233] As an example, such as Figure 19 As shown, the high-frequency terminal 8T has two contact portions 81, a base portion 86, and a substrate connection portion 83. The high-frequency terminal 8T is formed, for example, by punching and bending a metal plate.

[0234] The base 86 is formed in a U-shape that opens downwards (Dd). The substrate connecting portion 83 is connected to the upper end of the base 86. One contact portion 81 protrudes to the left (Dl) from the left end of the base 86, and the other contact portion 81 protrudes to the right (Dr) from the right end of the base 86.

[0235] In the process of connecting socket S1 and plug H1, such as Figure 20 As shown, each high-frequency terminal 4T is connected to its corresponding high-frequency terminal 8T. That is, a high-frequency terminal 8T is inserted between the two contact portions 41 of the high-frequency terminal 4T. As a result, each of the two contact portions 41 contacts its corresponding contact portion 81. In addition, at this time, the gap between the two contact portions 41 is pressed open in the left-right direction Dlr.

[0236] Alternatively, the shapes of terminals 4 and 8 can be configured as follows. Since the low-frequency terminal 4P (8P) may be connected to power supply wiring and grounding, the width of the low-frequency terminal 4P (8P) can be made larger than the width of the high-frequency terminal 4T (8T) to achieve low resistance. Furthermore, the contact area between the low-frequency terminal 4P and the low-frequency terminal 8P can be made larger than the contact area between the high-frequency terminal 4T and the high-frequency terminal 8T to achieve low resistance in the low-frequency terminals 4P and 8P. Additionally, to allow high-speed signals to pass through the high-frequency terminal 4T (8T), the high-frequency terminal 4T (8T) can be configured to match the characteristic impedance of the signal lines formed on the circuit board 150 (550).

[0237] Alternatively, in either the socket S1 or the plug H1, the shape of the low-frequency terminal 4P (8P) may differ from the shape of the high-frequency terminal 4T (8T).

[0238] (Other variations of the implementation method)

[0239] Other variations of the embodiments are listed below. These variations can also be implemented through appropriate combinations. Furthermore, these variations can also be implemented through appropriate combinations with variation 1 described above.

[0240] The outer shield 1 (5) and the inner shield 3 (7) are not limited to being electrically connected to each other by means of conductors 180 (580) of circuit board 150 (550), but can also be electrically connected to each other by means of other conductive components.

[0241] Alternatively, at least one of the outer shield 1 (5), the plurality of inner shields 3 (7) and the plurality of terminals 4 (8) may come into contact with the conductor 170 (570) and thereby be electrically connected to the conductor 170 (570).

[0242] like Figure 21 As shown, it can also be that in the socket S1, at least one of the two top regions r1 of the inner shield 3 (in) Figure 21 The inner shield 3 (7) and the outer shield 1 are directly connected. Similarly, in the plug H1, at least one of the two top regions r7 of the inner shield 7 is directly connected to the outer shield 5. For example, the length of the inner shield 3 (7) may be longer than in the embodiment, and the inner shield 3 (7) may be connected to the outer shield 1 (5) by means of welding, pressing or riveting. Alternatively, the portion of the inner shield 3 (7) including the top region r1 (r7) and at least a portion of the outer shield 1 (5) may be formed by a single component. Furthermore, the inner shield 3 (7) and the outer shield 1 (5) may be seamlessly connected.

[0243] The extension 32 (or 72) is not limited to protruding from the base 31 (or 71) in the vertical direction Dud. For example, the extension 32 (or 72) may also protrude from the base 31 (or 71) in the front-back direction Dfb.

[0244] The number of structures in the embodiment is an example and is not limited to the number shown in the embodiment. For example, the number of extensions 32 (72) in the inner shield 3 (7) can be appropriately changed. In addition, the number of terminals 4 (8) in each connector (socket S1 and plug H1) can be appropriately changed. Furthermore, each connector may have only low-frequency terminal 4P (8P) as terminal 4 (8) or only high-frequency terminal 4T (8T) as terminal 4 (8).

[0245] In the embodiments, the portion formed as a recess or depression can be appropriately replaced with a through hole. Conversely, in the embodiments, the portion formed as a through hole can be appropriately replaced with a recess or depression.

[0246] In one embodiment, the parts joined by pressing can also be joined by insert molding. Conversely, in another embodiment, the parts joined by insert molding can also be joined by pressing. Alternatively, other joining methods, such as bonding, welding, or riveting, can be used instead of pressing or insert molding.

[0247] Alternatively, the outer shielding members 1 and 5 can be formed by, for example, forming, instead of deep drawing, thereby forming at least a portion (e.g., the entire outer peripheral surface 101, 501) of the surfaces of the outer shielding members 1 and 5 seamlessly. Alternatively, at least a portion of the surfaces of the outer shielding members 1 and 5 can be formed seamlessly by, for example, welding.

[0248] Alternatively, the multiple protrusions 56 of the outer shielding member 5 may be located on the inner peripheral surface 503 of the cylindrical portion 50 instead of on the outer peripheral surface 501.

[0249] Alternatively, a portion of the structure of the socket S1 in the embodiment may be appropriately applied to the plug H1. Conversely, a portion of the structure of the plug H1 in the embodiment may be appropriately applied to the socket S1. For example, a plurality of protrusions 56 may be provided on both the outer shields 1 and 5, or they may be provided only on the outer shield 1 of the outer shields 1 and 5.

[0250] In the implementation, the terms indicating directions such as up and down, front and back, left and right refer to relative directions determined only by the relative positional relationship between the structural components of the connector and the object-side connector, and do not refer to absolute directions such as vertical directions.

[0251] (Summarize)

[0252] The following technical solutions are disclosed based on the implementation methods described above.

[0253] The connector (receptacle S1, S2 or plug H1, H2) of the first technical solution has an outer shield (1, 1A or 5, 5A), terminals (4 or 8), and a housing (2, 2A or 6, 6A). The outer shield (1, 1A or 5, 5A) has a cylindrical portion (10 or 50). The cylindrical portion (10 or 50) is open at both ends in a predetermined direction. The terminals (4 or 8) are surrounded by the outer shield (1, 1A or 5, 5A). The terminals (4 or 8) are electrically connected to the target terminals of the target connector. The outer shield (1, 1A or 5, 5A) is fixed relative to the housing (2, 2A or 6, 6A). The housing (2, 2A or 6, 6A) holds the terminals (4 or 8). The outer shield (1, 1A, or 5, 5A) has a top surface (102 or 502), an outer peripheral surface (101 or 501) of the cylindrical portion (10 or 50), and an inner peripheral surface (103 or 503) of the cylindrical portion (10 or 50). The top surface (102 or 502) is located at one of the two ends of the cylindrical portion (10 or 50), described next, along the inner edge of the cylindrical portion (10 or 50). This end is the end that becomes the end of the object-side connector when transitioning from a non-connected state to a connected state between the connector and the object-side connector. At least one of the top surface (102 or 502), the outer peripheral surface (101 or 501), and the inner peripheral surface (103 or 503) is seamless along the entire circumference of the cylindrical portion (10 or 50).

[0254] According to the above structure, compared with the case where there are seams or cracks on the top surface (102 or 502), the outer peripheral surface (101 or 501) and the inner peripheral surface (103 or 503) respectively, the noise radiated from the outer shield (1, 1A or 5, 5A) can be reduced.

[0255] Furthermore, according to the first technical solution, in the connector (socket S1, S2 or plug H1, H2) of the second technical solution, at least one of the boundary portion (b1 or b3) between the top surface (102 or 502) and the outer peripheral surface (101 or 501) and the boundary portion (b2) between the top surface (102 or 502) and the inner peripheral surface (103 or 503) is seamless over the entire circumference of the cylindrical portion (10 or 50).

[0256] Based on the above structure, compared with the case where there are seams or cracks in each boundary part (b1, b2 or b3), the noise radiated from the outer shield (1, 1A or 5, 5A) can be reduced.

[0257] Furthermore, according to the first or second technical solution, in the connector (socket S1, S2 or plug H1, H2) of the third technical solution, the housing (2, 2A or 6, 6A) has an insertion portion (223 or 623). The outer shield (1, 1A or 5, 5A) has a shield protrusion (14 or 54). The shield protrusion (14 or 54) is a protrusion that inserts into the insertion portion (223 or 623).

[0258] Based on the above structure, the possibility of misalignment between the outer shield (1, 1A or 5, 5A) and the housing (2, 2A or 6, 6A) can be reduced.

[0259] Furthermore, according to any one of the first to third technical solutions, in the connector (socket S1, S2 or plug H1, H2) of the fourth technical solution, the outer peripheral surface (101 or 501) and the inner peripheral surface (103 or 503) are seamless around the entire circumference of the cylindrical portion (10 or 50).

[0260] According to the above structure, compared with the case where there are seams or cracks on the outer peripheral surface (101 or 501) and the inner peripheral surface (103 or 503) respectively, the noise radiated from the outer shield (1, 1A or 5, 5A) can be reduced.

[0261] Furthermore, according to any one of the first to fourth technical solutions, in the connector (receptacle S1, S2) of the fifth technical solution, the housing (2, 2A) has a cylindrical peripheral wall (22). The peripheral wall (22) surrounds the terminal (4). The peripheral wall (22) is continuous along the entire circumference of the peripheral wall (22).

[0262] Based on the above structure, the strength of the peripheral wall (22) can be ensured.

[0263] Furthermore, according to any one of the first to fifth technical solutions, in the connector (socket S1, S2 or plug H1, H2) of the sixth technical solution, the outer shield (1, 1A or 5, 5A) has a contact portion (inner peripheral surface 103 or protrusion 56). The contact portion contacts the outer shield of the target-side connector.

[0264] According to the above structure, the outer shield of the connector (1, 1A or 5, 5A) can be electrically connected to the outer shield of the target connector.

[0265] Furthermore, according to the sixth technical solution, in the connector (plug H1, H2) of the seventh technical solution, the outer shield (5, 5A) has a protrusion (56) as a contact portion on at least one of the outer peripheral surface (501) and inner peripheral surface (503) of the cylindrical portion (50).

[0266] Based on the above structure, even if there are slight dimensional deviations between the outer shields (5, 5A) of the connector and the outer shields (1, 1A) of the target connector, one outer shield can be pressed into the other. That is, the dimensional tolerances of the outer shields (5, 5A) of the connector and the outer shields (1, 1A) of the target connector can be improved.

[0267] Furthermore, according to the seventh technical solution, in the connector (plug H1, H2) of the eighth technical solution, the outer shield (5, 5A) has multiple protrusions (56). The multiple protrusions (56) are provided at intervals around the circumference of the cylindrical portion (50).

[0268] Based on the above structure, the dimensional tolerances of the outer shield (5, 5A) of the connector and the outer shield (1, 1A) of the object-side connector can be further improved.

[0269] Furthermore, according to the eighth technical solution, in the connector (socket S1, S2 or plug H1, H2) of the ninth technical solution, the maximum creepage distance between the plurality of protrusions (56) is less than 1 / 4 of the wavelength corresponding to the maximum frequency of the transmission signal flowing to the terminal.

[0270] Based on the above structure, the possibility of noise leakage from the area between multiple protrusions (56) (the area in the outer shield (5, 5A) that is not electrically connected to the outer shield (1, 1A) of the object-side connector) can be reduced.

[0271] Furthermore, according to any one of the 6th to 9th technical solutions, in the connector (socket S1, S2 or plug H1, H2) of the 10th technical solution, the terminal (4 or 8) has a force-feeling portion (47 or 85). The force-feeling portion (47 or 85) generates a snap-fit ​​sensation when the terminal (4 or 8) contacts the target-side terminal. During the transition from a non-connected state to a connected state between the connector and the target-side connector, after the force-feeling portion (47 or 85) of the connector contacts the target-side terminal, the contact portion (inner peripheral surface 103 or protrusion 56) of the outer shield (1, 1A or 5, 5A) of the connector contacts the outer shield of the target-side connector.

[0272] Based on the above structure, the positioning accuracy between the connector and the object-side connector can be improved.

[0273] Furthermore, according to the 10th technical solution, in the connector (socket S1, S2 or plug H1, H2) of the 11th technical solution, the terminal (4 or 8) has a substrate connection portion (45 or 83). The substrate connection portion (45 or 83) is electrically connected to the circuit board (150 or 550). When viewed from a predetermined direction, the substrate connection portion (45 or 83) is surrounded by an outer shield (1, 1A or 5, 5A).

[0274] Based on the above structure, the possibility of noise transmission occurring at the substrate connection portion (45 or 83) can be reduced.

[0275] Regarding structures other than the first technical solution, those structures that are not essential for the connectors (sockets S1, S2 or plugs H1, H2) can be appropriately omitted.

[0276] Furthermore, the connector device (100) of the 12th technical solution has a connector (socket S1, S2 or plug H1, H2) of any one of the 1st to 11th technical solutions and an object-side connector.

[0277] According to the above structure, compared with the case where there are seams or cracks on the top surface (102 or 502), the outer peripheral surface (101 or 501) and the inner peripheral surface (103 or 503) respectively, the noise radiated from the outer shield (1, 1A or 5, 5A) can be reduced.
