[0009] (1) Overview The connector and connector device according to the first embodiment will be described below with reference to the drawings. However, the following embodiment is merely one of various embodiments of the present disclosure. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, each figure described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component in the figure does not necessarily reflect the actual dimensional ratio.

[0010] As shown in FIG. 11, the connector device 100 includes a first connector (socket S1) and a second connector (header H1). In the following description, the first connector is also referred to as the "socket S1" and the second connector is also referred to as the "header H1". The socket S1 is connected to the header H1. At this time, the terminal 4 of the socket S1 is electrically connected to the terminal 8 of the header H1. From the perspective of the socket S1, the header H1 is a "mating connector" connected to the socket S1. Conversely, from the perspective of the header H1, the socket S1 is a "mating connector" connected to the header H1. That is, the connector device 100 includes a connector (socket S1 or header H1) and a mating connector. From the perspective of the socket S1, the terminal 8 of the header H1 is a "mating terminal" electrically connected to the terminal 4 of the socket S1. Conversely, from the perspective of the header H1, the terminal 4 of the socket S1 is a "mating terminal" electrically connected to the terminal 8 of the header H1.

[0011] (1.1) Feature 1 As shown in Figs. 1, 5, 9, and 13, the connector (socket S1 or header H1) of this embodiment includes 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 a mating terminal of a mating connector. The housing 2 (or 6) is fixed relative to the outer shield 1 (or 5). 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) are composed of a first tip region facing or directly coupled to the outer shield 1 (or 5), and a second tip region facing or directly coupled to the outer shield 1 (or 5). Among the multiple electrical closed loops described below, the longest loop length of the electrical closed loops LO1, LO2, and LO3 that do not surround other electrical closed loops is shorter than the wavelength corresponding to the maximum frequency of the transmission signal flowing through the terminal 4 (or 8). Each of the multiple electrical closed loops includes at least the outer shield 1 (or 5) and the inner shield 3 (or 7) among the outer shield 1 (or 5), the inner shield 3 (or 7), and two imaginary paths W7 and W8 (or W9 and W10) that connect the outer shield 1 (or 5) and the two tip regions r1 (or r7) by the shortest distance L1 (or L7), and surrounds the terminal 4 (or 8).

[0012] According to the above configuration, it is possible to reduce the possibility that resonance of the transmission signal occurs in the electrical closed loop.

[0013] In the present disclosure, the "maximum frequency of a transmission signal flowing through a terminal" refers to the maximum frequency of the carrier wave when transmitting a signal through a terminal, for example, when transmitting an RF signal, and to a frequency that is 3 to 5 times the harmonic of the clock frequency when transmitting a digital signal. The above maximum frequency is, for example, a value determined by a manufacturer that manufactures a connector according to the specifications of the connector, or a value determined by the standards of the connector. The above maximum frequency is, for example, described in a specification provided by the manufacturer as the maximum frequency value at which operation is guaranteed.

[0014] (1.2) Feature 2 As shown in Figs. 1, 4, 5, 8 and 9, the connector (socket S1 or header H1) of this embodiment includes an outer shield 1 (or 5), a terminal 4 (or 8) and a housing 2 (or 6). The outer shield 1 (or 5) has a cylindrical portion 10 (or 50). Both ends of the cylindrical portion 10 (or 50) are open in a predetermined direction. The terminal 4 (or 8) is surrounded by the outer shield 1 (or 5). The terminal 4 (or 8) is electrically connected to a mating terminal of a mating connector. The housing 2 (or 6) is fixed to the outer shield 1 (or 5). The housing 2 (or 6) holds the terminal 4 (or 8). The outer shield 1 (or 5) has a tip 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 tip surface 102 (or 502) is provided along the inner edge of the cylindrical portion 10 (or 50) at one end described below among both ends of the cylindrical portion 10 (or 50). The one end is an end that becomes the mating connector side when the connector and the mating connector transition from a non-connected state to a connected state. At least one of the tip surface 102 (or 502), the outer peripheral surface 101 (or 501), and the inner peripheral surface 103 (or 503) is seamless over the entire circumference in the circumferential direction of the cylindrical portion 10 (or 50).

[0015] In this disclosure, "seamless" refers to the absence of seams and discontinuities.

[0016] According to the above configuration, the noise radiated from the outer shield 1 (or 5) can be reduced compared to a case where there are seams or gaps in the tip surface 102 (or 502), the outer peripheral surface 101 (or 501), and the inner peripheral surface 103 (or 503).

[0017] (1.3) Feature 3 As shown in FIG. 1, FIG. 5, and FIG. 10, the connector (socket S1 or header H1) of this embodiment includes a plurality of terminals 4 (or 8). The plurality of terminals 4 (or 8) are electrically connected to a plurality of mating terminals of a mating connector. The connector further includes 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 mating connector are connected to each other by at least one of them moving toward the other in a first direction (in this embodiment, a vertical direction to be described later). The plurality of terminals 4 (or 8) include two terminals 4 (or 8). The two terminals 4 (or 8) are arranged on both sides of the inner shield 3 (or 7) in a second direction (in this embodiment, a front-rear direction to be described later) perpendicular to the first direction. The inner shield 3 (or 7) includes a base 31 (or 71) and an extension 32 (or 72). The base 31 (or 71) has a length in a direction along a third direction (in this embodiment, a left-right direction described later) perpendicular to both the first direction and the second direction. The extension 32 (or 72) protrudes from the base 31 (or 71). The housing 2 (or 6) has a shield holding portion (accommodation portion 28 or 68). The shield holding portion holds the extension 32 (or 72).

[0018] According to the above configuration, the two terminals 4 (or 8) are arranged on both sides of the inner shield 3 (or 7), so that the possibility of noise propagation between the two terminals 4 (or 8) can be reduced compared to the case where the inner shield 3 (or 7) is not present. Furthermore, since the extension 32 (or 72) of the connector is positioned by the shield holding portion (accommodation portion 28 or 68), the accuracy of alignment between the extension 32 (or 72) of the connector and the mating connector can be improved. Furthermore, in this embodiment, the extension 32 (or 72) of the connector is electrically connected to the inner shield of the mating connector. With the above configuration, the accuracy of electrical connection between the extension 32 (or 72) of the connector and the inner shield of the mating connector can be improved.

[0019] (1.4) Feature 4 As shown in Figs. 1, 2, 5 and 6, the connector (socket S1 or header H1) of this embodiment includes a plurality of terminals 4 (or 8), a housing 2 (or 6) and an inner shield 3 (or 7). The plurality of terminals 4 (or 8) are electrically connected to a plurality of mating terminals of a mating connector. The housing 2 (or 6) holds the plurality of terminals 4 (or 8). The connector and the mating connector are connected to each other by at least one of them moving toward the other in a first direction. The plurality of terminals 4 (or 8) include two terminals 4 (or 8). The two terminals 4 (or 8) are arranged on both sides of the inner shield 3 (or 7) in a second direction perpendicular to the first direction.

[0020] According to the above configuration, the possibility of noise propagation between the two terminals 4 (or 8) can be reduced compared to a case where the inner shield 3 (or 7) is not provided.

[0021] In the above configuration, the connector preferably further includes an outer shield 1 (or 5). The outer shield 1 (or 5) surrounds the multiple terminals 4 (or 8) and the inner shield 3 (or 7).

[0022] By providing the connector with the outer shield 1 (or 5), the possibility of noise propagation or radiation occurring between the inside and outside of the outer shield 1 (or 5) can be reduced.

[0023] (2)Details The connector (socket S1 and header H1) according to this embodiment will be described in detail below with reference to FIGS.

[0024] In the following description, unless otherwise specified, the direction in which the socket S1 and the header H1 are connected to or separated from each other is referred to as the up-down direction (also referred to as the "first direction"), and the header H1 side as viewed from the socket S1 is referred to as the upper side. The direction perpendicular to the up-down direction and the longitudinal direction of the housing 2 of the socket S1 is referred to as the front-rear direction (also referred to as the "second direction"). The direction perpendicular to both the up-down direction and the front-rear direction, that is, the short side direction of the housing 2 is referred to as the left-right direction (also referred to as the "third direction"). That is, the directions of up, down, front, rear, left, and right are defined as shown by the arrows of "up", "down", "front", "rear", "left", and "right" in FIG. 1 and the like. However, these directions are not intended to define the directions in which the socket S1 and the header H1 are used. The arrows indicating the directions in the drawings are merely shown for the purpose of explanation and do not have any substance.

[0025] As described above, the connector and the mating connector are connected to each other by at least one of them moving toward the other in the first direction. In this embodiment, the socket S1 is disposed below the header H1, and the socket S1 and the header H1 are connected to each other by at least one of the following: the socket S1 moves up and the header H1 moves down. Therefore, "the mating connector side when the connector and the mating connector transition from a non-connected state to a connected state" means the upper side when the socket S1 is the connector, and means the lower side when the header H1 is the connector.

[0026] The socket S1 and the header H1 of this embodiment are attached to a circuit board 150 or 550 (see FIG. 10), such as a printed wiring board or a flexible printed wiring board. The socket S1 and the header H1 are used to electrically connect between a plurality of circuit boards mounted on a mobile terminal such as a smartphone. Of course, the purpose of the socket S1 and the header H1 is not limited to the purpose of electrically connecting between a plurality of circuit boards, and the socket S1 and the header H1 may be used in electronic devices other than a mobile terminal, such as a camera module. The purpose of the socket S1 and the header H1 is not limited to the purpose of electrically connecting between a plurality of circuit boards, and may be the purpose of electrically connecting between a plurality of components, such as between a circuit board and a display, or between a circuit board and a battery.

[0027] The socket S1 and the header H1 may be provided in a state where they are not connected to the circuit board 150 or 550, respectively.

[0028] (2.1) Socket configuration First, the configuration of the socket S1 according to this embodiment will be described.

[0029] The socket S1 is two-fold symmetrical with respect to an axis passing through the center of the socket S1 and extending in the up-down direction. As shown in FIG. 1, the socket S1 includes an outer shield 1, a housing 2, a plurality (two) of inner shields 3, and a plurality (eight) of terminals 4. Each of the outer shield 1 and the plurality of inner shields 3 is an electrostatic shield. The outer shield 1 surrounds the plurality of terminals 4. That is, the outer shield 1 is disposed outside the plurality of terminals 4. The plurality of inner shields 3 are disposed inside the outer shield 1. Moreover, the plurality of inner shields 3 are disposed inside the housing 2.

[0030] A circuit board 150 (see FIG. 9) is mechanically and electrically connected to the socket S1. In this embodiment, the circuit board 150 is a double-sided board, but the circuit board 150 may be a laminated board. The circuit board 150 has a base material 160 (see FIG. 9) and conductors 170 and 180 (see FIG. 9). The base material 160 is, for example, a semiconductor base material or a glass base material. The conductor 170 is a pattern of copper foil or the like provided on the surface of the base material 160. The conductor 170 is, for example, provided on substantially the entire surface of the base material 160 on the side to which the socket S1 is connected. The conductor 180 is, for example, solder. The conductor 180 is provided in a predetermined region (land) of the conductor 170. The conductor 170 is electrically connected to the outer shield 1, the multiple inner shields 3, and the multiple terminals 4 via the conductor 180 (solder). The outer shield 1 and the multiple inner shields 3 are, for example, electrically connected to a ground provided on the circuit board 150. In FIG. 2, the area where the conductor 180 (solder) is provided is shown by a two-dot chain line.

[0031] (2.1.1) Socket housing The housing 2 is a resin molded body. The housing 2 has electrical insulation properties. As shown in Figs. 1 to 3, the housing 2 has a bottom wall 21 and a peripheral wall 22. The bottom wall 21 is formed in a rectangular shape that is longer in the front-to-rear direction than in the left-to-right direction in a plan view. The peripheral wall 22 protrudes upward from the entire periphery of the outer periphery of one surface (top surface) in the thickness direction of the bottom wall 21. The housing 2 has a rectangular parallelepiped shape that is flattened in the vertical direction, and has a recess 24 (see Fig. 3) surrounded by the peripheral wall 22 in the center of the top surface, which is the surface facing the header H1, among both surfaces in the vertical direction.

[0032] The peripheral wall 22 has a cylindrical shape. The peripheral wall 22 surrounds the multiple terminals 4. The peripheral wall 22 is continuous over the entire circumference of the peripheral wall 22 in the circumferential direction. In other words, the peripheral wall 22 is formed without any breaks over the entire circumference of the peripheral wall 22 in the circumferential direction. As shown in FIG. 1, the peripheral wall 22 includes two first peripheral walls 221 and two second peripheral walls 222. The two first peripheral walls 221 are portions of the peripheral wall 22 that extend approximately parallel to each other in the front-rear direction and face each other in the left-right direction via the recess 24. The two second peripheral walls 222 are portions of the peripheral wall 22 that extend approximately parallel to each other in the left-right direction and face each other in the front-rear direction via the recess 24. The two second peripheral walls 222 connect the ends of the two first peripheral walls 221 to each other. That is, the housing 2 has a shape in which one opening surface (lower surface) of a peripheral wall 22 in the shape of a rectangular cylinder having a square cross section is closed by a bottom wall 21.

[0033] As shown in FIG. 3, the housing 2 further includes a first wall portion 25, a second wall portion 26, and a third wall portion 27. The first wall portion 25, the second wall portion 26, and the third wall portion 27 protrude upward from the bottom wall 21. The first wall portion 25, the second wall portion 26, and the third wall portion 27 are disposed in the recessed portion 24. That is, the first wall portion 25, the second wall portion 26, and the third wall portion 27 are surrounded by the peripheral wall 22. The first wall portion 25, the second wall portion 26, and the third wall portion 27 each have a rectangular parallelepiped shape. When viewed from the top-bottom direction, each of the first wall portion 25, the second wall portion 26, and the third wall portion 27 is longer in the front-rear direction than in the left-right direction. That is, each of the first wall portion 25, the second wall portion 26, and the third wall portion 27 is a wall portion having a thickness in a direction along the third direction (left-right direction). The first wall portion 25, the second wall portion 26, and the third wall portion 27 are arranged in this order from left to right.

[0034] Each of the multiple wall portions (first wall portion 25, second wall portion 26, and third wall portion 27) has multiple (two) accommodating portions 28. An extension portion 32 of the inner shield 3 is accommodated in each of the multiple accommodating portions 28. Each of the multiple accommodating portions 28 is a through hole provided in the wall portion. The accommodating portions 28 penetrate the wall portions in the up-down direction. The accommodating portions 28 also penetrate the bottom wall 21 in the up-down direction. Also, when viewed from the up-down direction, the accommodating portions 28 provided in the first wall portion 25 and the third wall portion 27 are recesses recessed from the side surface (plane intersecting with the left-right direction) of the first wall portion 25 (third wall portion 27).

[0035] Each of the multiple wall portions (first wall portion 25, second wall portion 26, and third 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 wall portion penetrates in the vertical direction at the terminal holding portion 29. Also, when viewed from the vertical direction, the terminal holding portion 29 is a recess recessed from a side surface of the wall portion (a surface intersecting with the left-right direction). The multiple terminal holding portions 29 correspond to each other in pairs, and two corresponding terminal holding portions 29 are lined up in the left-right direction. A portion of the bottom wall 21 between two corresponding terminal holding portions 29 forms a through hole 211 into which the terminal 4 is inserted.

[0036] The terminals 4 are fixed to the housing 2 by press-fitting. That is, the terminals 4 are held in the housing 2 by being pushed in one direction (upward) into the housing 2. In this embodiment, eight terminals 4 are fixed to the housing 2. The eight terminals 4 are arranged in two rows. That is, of the eight terminals 4, four terminals 4 constitute a first row, and the remaining four terminals 4 constitute a second row. The four terminals 4 in each row are arranged in the front-rear direction. Each of the four terminals 4 constituting the first row is held by the terminal holding portion 29 of the first wall portion 25 and the terminal holding portion 29 of the second wall portion 26. Each of the four terminals 4 constituting the second row is held by the terminal holding portion 29 of the second wall portion 26 and the terminal holding portion 29 of the third wall portion 27. That is, each terminal 4 is disposed between two walls and supported from both sides by the two walls.

[0037] 2, the bottom wall 21 has a plurality of notches 212. The plurality of notches 212 are provided at positions facing board connection portions 45 (described later) of the terminals 4 when viewed from the top-bottom direction. The bottom wall 21 also has a plurality (two) of accommodating grooves 213. Each accommodating groove 213 is a groove provided on the lower surface of the bottom wall 21. The accommodating groove 213 is longer in the left-right direction than in the front-back direction. The accommodating groove 213 accommodates the base portion 31 of the inner shield 3.

[0038] The peripheral wall 22 has a plurality (four) of insertion portions 223. The plurality (four) of insertion portions 223 are recesses recessed from the side surfaces (inner surfaces) of the two first peripheral walls 221 and the two second peripheral walls 222. As described below, a shield protrusion 14 that is a part of the outer shield 1 is inserted into each of the plurality (four) of insertion portions 223.

[0039] (2.1.2) Outer Shield of Socket The outer shield 1 surrounds the multiple terminals 4 and the multiple inner shields 3. The outer shield 1 contains a metal as a main material or a material such as plating that constitutes the surface. Here, as an example, the outer shield 1 is formed using a metal as a main material. As shown in Figs. 1 and 4, the outer shield 1 has a cylindrical portion 10 and multiple (four) shield protrusions 14. The cylindrical portion 10 includes an outer peripheral wall 11, a top wall 12, and an inner peripheral wall 13.

[0040] The outer peripheral wall 11 has a rectangular cylindrical shape with a square cross section. The outer peripheral wall 11 includes two first outer peripheral walls 111 and two second outer peripheral walls 112. The two first outer peripheral walls 111 are portions of the outer peripheral wall 11 that extend approximately parallel to the front-rear direction and face each other in the left-right direction. The two second outer peripheral walls 112 are portions of the outer peripheral wall 11 that extend approximately parallel to the left-right direction and face each other in the front-rear direction. The two second outer peripheral walls 112 connect the ends of the two first outer peripheral walls 111 to each other. The lower ends (lower surfaces) of the first outer peripheral wall 111 and the second outer peripheral wall 112 are parallel to a plane including the front-rear and left-right directions and are formed in approximately the same plane.

[0041] The top wall 12 has a rectangular frame shape when viewed from the top-bottom direction. The top wall 12 is connected to the upper end of the outer peripheral wall 11 and extends toward the inside of the outer peripheral wall 11 when viewed from the top-bottom direction.

[0042] The inner peripheral wall 13 is provided inside the outer peripheral wall 11. The inner peripheral wall 13 has a rectangular 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.

[0043] The inner circumferential wall 13 includes two first inner circumferential walls 131 and two second inner circumferential walls 132. The two first inner circumferential walls 131 are portions of the inner circumferential wall 13 that extend approximately parallel to each other in the front-rear direction and face each other in the left-right direction. The two second inner circumferential walls 132 are portions of the inner circumferential wall 13 that extend approximately parallel to each other in the left-right direction and face each other in the front-rear direction. The two second inner circumferential walls 132 connect end portions of the two first inner circumferential walls 131 to each other.

[0044] The outer peripheral wall 11, the top wall 12, and the inner peripheral wall 13 form a cylindrical portion 10 having both ends open in a first direction (vertical direction). The outer peripheral surface of the outer peripheral wall 11 corresponds to an outer peripheral surface 101 of the cylindrical portion 10. The inner peripheral surface of the inner peripheral wall 13 corresponds to an inner peripheral surface 103 of the cylindrical portion 10. The outer shield 1 also has a tip surface 102. The tip surface 102 is provided at one end (upper end) of both ends of the cylindrical portion 10 in the first direction, which is on the mating connector side when the connector (here, the socket S1) and the mating connector (here, the header H1) transition from a non-connected state to a connected state. The tip surface 102 is provided in an annular shape along the inner edge of the cylindrical portion 10. Here, the upper surface of the top wall 12 corresponds to the tip surface 102. The inner edge of the tip surface 102 corresponds to the inner edge of the cylindrical portion 10 at the upper end of the cylindrical portion 10.

[0045] The boundary portion b1 between the tip surface 102 and the outer peripheral surface 101 is an arc-shaped surface when viewed from the front-rear direction (see FIG. 9). The boundary portion b2 between the tip surface 102 and the inner peripheral surface 103 is an arc-shaped surface when viewed from the front-rear direction (see FIG. 9). Here, the tip surface 102 is defined as a region of the outer surface of the cylindrical portion 10 where the acute angle with respect to the vertical direction is 0 degrees or more and less than 45 degrees. The outer surface where the acute angle is 45 degrees or more is defined as the outer peripheral surface 101, and the inner surface where the acute angle is 45 degrees or more is defined as the inner peripheral surface 103. The boundary portion b1 includes a part of the tip surface 102 and a part of the outer peripheral surface 101 over the entire circumference of the cylindrical portion 10 in the circumferential direction. The boundary portion b2 includes a part of the tip surface 102 and a part of the inner peripheral surface 103 over the entire circumference of the cylindrical portion 10 in the circumferential direction.

[0046] The multiple (four) shield protrusions 14 are provided corresponding to each of the two first inner circumferential walls 131 and the two second inner circumferential walls 132. Each shield protrusion 14 protrudes downward from the corresponding first inner circumferential wall 131 or second inner circumferential wall 132. The multiple (four) shield protrusions 14 correspond one-to-one to the multiple (four) insertion portions 223 (see FIG. 2) provided in the housing 2. Each shield protrusion 14 is inserted into the corresponding insertion portion 223.

[0047] The outer shield 1 is insert molded into the housing 2. More specifically, the outer shield 1 is insert molded into the housing 2 such that the peripheral wall 22 of the housing 2 fits between the outer peripheral wall 11 and the inner peripheral wall 13 of the outer shield 1.

[0048] The surface of the outer shield 1 is formed without seams over its entirety. The outer shield 1 is formed, for example, by drawing, and as a result, the surface of the outer shield 1 is formed without seams over its entirety. In this embodiment, at least the outer peripheral surface 101 and the inner peripheral surface 103 of the surface of the outer shield 1 are seamless over the entire circumferential direction of the tubular portion 10 (i.e., there are no seams or discontinuities). In this embodiment, furthermore, the tip surface 102 is seamless over the entire circumferential direction of the tubular portion 10.

[0049] For example, focusing on the outer peripheral surface 101, as shown in Fig. 4, the outer peripheral surface 101 includes an outer surface 1110 of each of the two first outer peripheral walls 111 and an outer surface 1120 of each of the two second outer peripheral walls 112. Each of the outer surfaces 1110 and 1120 is seamless. Furthermore, the outer surfaces 1110 and 1120, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the outer peripheral surface 101 is seamless over the entire circumferential direction of the tubular portion 10.

[0050] 4, the inner circumferential surface 103 includes an outer surface 1310 of each of the two first inner circumferential walls 131 and an outer surface 1320 of each of the two second inner circumferential walls 132. Each of the outer surfaces 1310 and 1320 is seamless. Furthermore, the outer surfaces 1310 and 1320, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the inner circumferential surface 103 is seamless over the entire circumferential direction of the tubular portion 10.

[0051] At least one of the boundary portion b1 between the tip surface 102 and the outer peripheral surface 101 and the boundary portion b2 between the tip surface 102 and the inner peripheral surface 103 (in this embodiment, both) is seamless over the entire circumferential direction of the tubular portion 10.

[0052] For example, in the upper right corner of FIG. 4 (corner portion of the outer shield 1), the outer surface 1110 of the first outer peripheral wall 111, the outer surface 1120 of the second outer peripheral wall 112, and the tip surface 102 are seamlessly connected. That is, the outer surface 1110, the outer surface 1120, and the tip surface 102, which are three surfaces whose normal directions are different from each other, are seamlessly connected. Also, in the right corner of FIG. 4, the outer surface 1110 and the tip surface 102, which are two surfaces whose normal directions are different from each other, are seamlessly connected. Furthermore, in FIG. 4, the outer surface 1120 and the tip surface 102, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the boundary portion b1 is seamless over the entire circumferential direction of the tubular portion 10.

[0053] Also, for example, at the bottom left of FIG. 4 (corner portion of the outer shield 1), the outer surface 1310 of the first inner circumferential wall 131, the outer surface 1320 of the second inner circumferential wall 132, and the tip surface 102 are seamlessly connected. That is, the outer surface 1310, the outer surface 1320, and the tip surface 102, which are three surfaces whose normal directions are different from each other, are seamlessly connected. Also, at the left of FIG. 4, the outer surface 1310 and the tip surface 102, which are two surfaces whose normal directions are different from each other, are seamlessly connected. Furthermore, at the bottom of FIG. 4, the outer surface 1320 and the tip surface 102, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the boundary portion b2 is seamless over the entire circumferential direction of the tubular portion 10.

[0054] (2.1.3) Inner shield of socket In this embodiment, the two inner shields 3 have the same shape. The inner shields 3 contain metal as a main material or a material such as plating that constitutes the surface. Here, as an example, the inner shield 3 is formed with metal as a main material. As shown in Figs. 1 and 9, the inner shield 3 has a base 31 and multiple (three) extensions 32 (two first extensions 33 and one second extension 34).

[0055] The base 31 has a length in the direction along the third direction (left-right direction). The shape of the base 31 is plate-like. When viewed in the thickness direction (front-back direction) of the base 31, the base 31 is longer in the left-right direction than in the up-down direction. The base 31 is accommodated in an accommodating groove 213 provided in the bottom wall 21 of the housing 2.

[0056] As shown in Fig. 9, the multiple extensions 32 protrude upward from the base 31. That is, the multiple extensions 32 protrude along the first direction (vertical direction) in a direction toward the mating connector when the connector (here, the socket S1) and the mating connector (here, the header H1) transition from a non-connected state to a connected state. Each extension 32 is plate-shaped. When viewed from the thickness direction (front-rear direction) of each extension 32, each extension 32 is longer in the vertical direction than in the horizontal direction. The thickness direction of each extension 32 may be the horizontal direction.

[0057] The first extension 33 includes an extension main body 331 and a contact portion 332. The extension main body 331 is a portion that protrudes from the base 31. The contact portion 332 is a portion that comes into contact with the inner shield 7 of the mating connector (header H1). The contact portion 332 protrudes from the extension main body 331. The contact portion 332 is provided on a surface (here, the left or right surface) of the first extension 33 (extension main body 331) that is along the length direction of the first extension 33. That is, the contact portion 332 protrudes from the extension main body 331 in the left-right direction.

[0058] The contact portions 332 of the two first extension portions 33 face each other in the left-right direction. Each contact portion 332 comes into contact with the contact portion 720 of the inner shield 7 of the header H1 (see FIG. 10). As a result, the two inner shields 3 are electrically connected to the corresponding one of the two inner shields 7 of the header H1. Specifically, the two extension portions 72 of the inner shield 7 are inserted between the two first extension portions 33 of the inner shield 3. At this time, the two extension portions 72 are pressed against the two first extension portions 33 due to the elasticity of the two extension portions 72 and the two first extension portions 33.

[0059] The second extension portion 34 includes an extension portion main body 341 and a plurality (two) of holding protrusions 342. The extension portion main body 341 is a portion that protrudes from the base portion 31. The two holding protrusions 342 protrude from the extension portion main body 341. The two holding protrusions 342 are provided on the left and right ends of the extension portion main body 341. That is, one of the two holding protrusions 342 protrudes leftward from the extension portion main body 341, and the other protrudes rightward from the extension portion main body 341.

[0060] The socket S1 has three extensions 32 on each of the two inner shields 3. That is, the socket S1 has a total of six extensions 32. The six accommodation sections 28 (see FIG. 3) provided in the housing 2 correspond one-to-one to the six extensions 32. Each extension 32 is accommodated in the corresponding accommodation section 28. More specifically, the first extension 33 is accommodated in the accommodation section 28 of the first wall section 25 and the third wall section 27, and the second extension 34 is accommodated in the accommodation section 28 of the second wall section 26. The width of the second extension 34 in the left-right direction including the two holding protrusions 342 is slightly larger than the width of the accommodation section 28 in the left-right direction. The inner shield 3 is fixed to the housing 2 by press-fitting. That is, the inner shield 3 is held in 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 holding protrusions 342 sandwiched between the inner surface of the accommodating portion 28 .

[0061] Here, the accommodation space of each of the two first extensions 33 in the shield holding portion (accommodating portion 28) is larger than that of each of the two first extensions 33. That is, a play is provided in the alignment between each of the two first extensions 33 and the inner surface of the accommodating portion 28. The function of holding the inner shield 3 in the housing 2 is realized by at least the second extension 34. That is, the inner shield 3 is held in the housing 2 by at least the second extension 34 being press-fitted into the accommodating portion 28. In short, the multiple extensions 32 include the first extension 33 including the abutment portion 332 that contacts the inner shield 7 of the mating connector (here, the header H1) and the second extension 34 that is held in the shield holding portion (accommodating portion 28). However, the second extension 34 may also include an abutment portion that contacts the inner shield 7 of the mating connector (here, the header H1).

[0062] 9, 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 tip regions r1 facing the outer shield 1. The two tip regions r1 are provided at both ends (left and right ends) of the base 31 in the longitudinal direction.

[0063] Here, the outer shield 1 has a first end e1 and a second end e2. The first end e1 is an end (upper end) that becomes the mating connector side when a connector (here, the socket S1) and a mating connector (here, the header H1) transition from a non-connected state to a connected state. The second end e2 is an end (lower end) opposite the first end e1. Note that here, the second end e2 is a region that covers the entire circumferential circumference of the tubular portion 10. The outer shield 1 faces two tip regions r1 in a region including the second end e2.

[0064] The outer shield 1 faces at least one of the two tip regions r1 across a gap g1 in a region including the second end e2. As shown in FIG. 9, the conductors 170 and 180 of the circuit board 150 are electrically connected to the outer shield 1. The conductors 170 and 180 are provided so as to bridge the second end e2 of the outer shield 1 across the two tip regions r1 of the inner shield 3, respectively. That is, the outer shield 1 is electrically connected to the inner shield 3 through the conductors 170 and 180. On the other hand, in a state in which the circuit board 150 is not present, the outer shield 1 is electrically insulated from at least one of the two tip regions r1 (both in this embodiment) through the gap g1. The shortest distance L1 between the outer shield 1 and at least one of the two tip regions r1 in the gap g1 is 0.01 mm or more and 0.1 mm or less.

[0065] The inner shield 3 has a first end e3 and a second end e4. The first end e3 is an end (upper end) that is on the mating connector side when the connector (here, the socket S1) and the mating connector (here, the header H1) transition from a non-connected state to a connected state. The second end e4 is an end (lower end) opposite to the first end e3. The inner shield 3 has a connection surface 310 (lower surface) at the second end e4 that is electrically connected to the circuit board 150. The connection surface 310 is planar and continuous across the two tip regions r1. More specifically, the connection surface 310 is a rectangular plane that connects the two tip regions r1.

[0066] (2.1.4) Socket terminals (2.1.4.1) Placement 2 and 3, the plurality (eight) of terminals 4 include a plurality (six) of low-frequency terminals 4P and a plurality (two) of high-frequency terminals 4T. Each terminal 4 is inserted into a through-hole 211 in the bottom wall 21 of the housing 2 and held by a terminal holding portion 29.

[0067] The two high-frequency terminals 4T are disposed on either side of 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 can reduce the possibility of noise propagation between the two high-frequency terminals 4T.

[0068] More specifically, the two high-frequency terminals 4T are disposed on both sides of at least one inner shield 3 in the second direction (front-rear direction), i.e., on the front and rear sides of the inner shield 3. Focusing on one of the two inner shields 3 in Fig. 2, one high-frequency terminal 4T is disposed in front of the inner shield 3, and the remaining one high-frequency terminal 4T is disposed behind the inner shield 3. Furthermore, two inner shields 3 are disposed between the two high-frequency terminals 4T. The length direction (left-right direction) of the inner shield 3 is a direction that intersects with the direction in which the two high-frequency terminals 4T are arranged side by side (approximately the front-rear direction).

[0069] The six low-frequency terminals 4P are arranged between two inner shields 3. That is, the space in which one of the two high-frequency terminals 4T is arranged and the space in which the six low-frequency terminals 4P are arranged are separated by one of the two inner shields 3. Furthermore, the space in which the other of the two high-frequency terminals 4T is arranged and the space in which the six low-frequency terminals 4P are arranged are separated by the other of the two inner shields 3. The six low-frequency terminals 4P are arranged in two rows of three each in the front-rear direction.

[0070] The three low-frequency terminals 4P in each row are arranged at equal pitches in the front-rear direction. Moreover, a high-frequency terminal 4T is arranged in front of or behind the low-frequency terminal 4P at the end of each row. The pitch between the low-frequency terminal 4P and the high-frequency terminal 4T is an integer multiple (twice in this embodiment) of the pitch of the three low-frequency terminals 4P. This arrangement makes it easy to collectively incorporate the six low-frequency terminals 4P and the two high-frequency terminals 4T into the housing 2.

[0071] In this embodiment, the pitch between the low frequency terminal 4P and the high frequency terminal 4T is longer than the pitch between the three low frequency terminals 4P, which makes it possible to secure a space for disposing the inner shield 3 between the low frequency terminal 4P and the high frequency terminal 4T.

[0072] Since a space in which a plurality of low frequency terminals 4P are arranged is provided between the two high frequency terminals 4T, the distance between the two high frequency terminals 4T can be secured. This can further reduce the possibility of noise propagation between the two high frequency terminals 4T. In addition, the two high frequency terminals 4T are arranged at diagonal positions inside the peripheral wall 22 of the housing 2. This can further increase the distance between the two high frequency terminals 4T.

[0073] The two high frequency terminals 4T are electrically connected to a signal line patterned with a conductor 170 on the circuit board 150. At least one of the six low frequency terminals 4P is electrically connected to a power supply line patterned with a conductor 170 on the circuit board 150. A signal having a higher frequency is transmitted through the two high frequency terminals 4T compared to the six low frequency terminals 4P. The frequency of the signal transmitted through the two high frequency terminals 4T is, for example, about 5 to 50 GHz.

[0074] At least one of the six low-frequency terminals 4P may be electrically connected to the inner shield 3. As a result, at least one of the six low-frequency terminals 4P has the same potential as the inner shield 3. Specifically, the potential of at least one of the six low-frequency terminals 4P and the potential of the inner shield 3 are the ground potential. At least one of the six low-frequency terminals 4P may be electrically connected to the inner shield 3 via, for example, the conductors 170 and 180 of the circuit board 150. Note that at least one of the six low-frequency terminals 4P may be electrically connected to the inner shield 3 without using the circuit board 150.

[0075] (2.1.4.2) Shape The terminals 4 have the same shape. Each terminal 4 is formed, for example, by punching and bending a metal plate. As shown in Fig. 11, each terminal 4 has a (first) contact portion 41, a base portion 42, a connecting portion 43, a protruding portion 44, a board connecting portion 45, and a (second) contact portion 46.

[0076] The board connection portion 45 is electrically connected to, for example, the conductor 180 (solder) of the circuit board 150. That is, the board connection portion 45 is joined to the circuit board 150 by a joining means such as soldering. This electrically and mechanically connects the circuit board 150 and the terminal 4. As shown in FIG. 2, the board connection portion 45 is surrounded by the outer shield 1 when viewed from a first direction (vertical direction). Furthermore, at least a part of the board connection portion 45 and at least a part of the outer shield 1 exist on a plane perpendicular to the vertical direction.

[0077] The connecting portion 43 is formed in a U-shape that is open downward. The connecting portion 43 connects the upper end of the base portion 42 to the upper end of the contact portion 41. The lower end of the base portion 42 is connected to the board connection portion 45.

[0078] The protruding portion 44 is formed in a U-shape that is open upward. The protruding portion 44 connects a lower end of the contact portion 41 to the contact portion 46. The contact portion 41, which is the first contact portion, and the contact portion 46, which is the second contact portion, face each other in the left-right direction. In this embodiment, at least the connecting portion 43 and the protruding portion 44 of the terminal 4 have elasticity.

[0079] When the terminal 4 is held in the housing 2, at least a part of the contact portion 41 and the contact portion 46 is exposed when viewed from above. The contact portion 41 and the contact portion 46 come into contact with corresponding terminals 8 among a plurality of terminals 8 (mating terminals) of the header H1 (mating connector) and are electrically connected to the terminals 8 (see FIG. 12). Specifically, the contact portion 81 and the contact portion 84 of the terminal 8 are inserted between the contact portion 41 and the contact portion 46. At this time, the elasticity of the protruding portion 44 presses the contact portion 41 and the contact portion 46 against the terminal 8.

[0080] The terminal 4 further has a force sense portion 47. The force sense portion 47 generates a clicking sensation when the terminal 4 contacts the terminal 8 (counter terminal). The force sense portion 47 is a protrusion protruding from the contact portion 41. When the force sense portion 85 (protrusion) of the terminal 8 passes over the force sense portion 47, a clicking sensation is generated. Specifically, the force sense portion 85 moves downward and passes over the force sense portion 47, so that the magnitude of the force acting between the terminal 4 and the terminal 8 decreases, and the worker who connects the terminal 4 and the terminal 8 perceives the decrease in the magnitude of the force as a clicking sensation. The worker can know the progress of the connection between the socket S1 and the header H1 by perceiving the clicking sensation. The connection between the socket S1 and the header H1 and the associated connection between the terminal 4 and the terminal 8 are not limited to be performed by human hands, but may be performed by a machine.

[0081] When the terminals 4 and 8 are connected, the contact portion 46 is inserted into the recess 840 of the terminal 8. When the terminals 4 and 8 are shifted from a connected state to a non-connected state, a certain amount of force is required for the force sense portion 85 to move upward and overcome the force sense portion 47, and for the contact portion 46 to escape from the recess 840. In this way, the pair of the force sense portion 85 and the force sense portion 47, and the pair of the contact portion 46 and the recess 840 each constitute a locking mechanism that can maintain the connected state between the socket S1 and the header H1.

[0082] As shown in FIG. 3, the abutting portion 332 of the inner shield 3 and the contact portion 41 of at least one of the multiple terminals 4 are aligned in the second direction (front-rear direction).

[0083] (2.1.5) Socket side circuit board The socket S1 is electrically connected to a conductor 180 (solder) of the circuit board 150. In FIG. 2, the area of ​​the lower surface of the socket S1 where the conductor 180 is provided is shown by a two-dot chain line. A part of the conductor 180 is provided on the lower surface of the outer shield 1 along the circumferential direction of the outer shield 1. Here, the conductors 180 are provided on the lower surface of the outer shield 1 in each of a plurality of areas that are spaced apart in the circumferential direction of the outer shield 1. However, the conductor 180 may be provided on the lower surface of the outer shield 1 continuously over the entire circumference of the outer shield 1 in the circumferential direction. In other words, the outer shield 1 may be in contact with the conductor 180 continuously over the entire circumference of the outer shield 1 in the circumferential direction.

[0084] Also, a portion of the conductor 180 is provided so as to bridge the outer shield 1 and each inner shield 3. Furthermore, a portion of the conductor 180 is provided on the lower surface of each inner shield 3 along the longitudinal direction of the inner shield 3. Here, the conductors 180 are provided on the lower surface of each inner shield 3 in each of a plurality of (three) regions spaced apart in the longitudinal direction of the inner shield 3. However, the conductors 180 may be provided continuously on the lower surface of each inner shield 3 over the entire longitudinal direction of the inner shield 3. In other words, the inner shield 3 may be in contact with the conductor 180 continuously over the entire longitudinal direction.

[0085] A portion of the conductor 180 is thus electrically connected to the outer shield 1 and each inner shield 3, and is also electrically connected to one of the conductors 170 of the circuit board 150 that is at ground potential. That is, the potential of the outer shield 1 and each inner shield 3 is at ground potential. It is preferable that most of the surface of the substrate 160 on the side to which the socket S1 is connected is occupied by the conductor 170 at ground potential. That is, it is preferable that a so-called ground plane is provided on the circuit board 150. This enhances the shielding effect.

[0086] Also, a portion of the conductor 180 is electrically connected to the board connection portion 45 of the terminal 4. The terminal 4 is electrically connected to an appropriate circuit or the like via the conductor 170 (wiring pattern) of the circuit board 150. For example, the multiple high frequency terminals 4T are electrically connected to a circuit that processes signals. Also, for example, at least a portion of the multiple low frequency terminals 4P are electrically connected to wiring that transmits a signal at a lower frequency than the signal transmitted by the high frequency terminal 4T, or to a power supply circuit or ground.

[0087] (2.1.6) Socket Electrical Closed Loop FIG. 13 shows a schematic arrangement of an outer shield 1, a plurality (two) of inner shields 3, and a plurality (eight) of terminals 4 as viewed from below.

[0088] In the socket S1, at least a plurality (three) of electrical closed loops LO1, LO2, LO3 are formed, which will be described below. Each of the electrical closed loops LO1, LO2, LO3 includes at least the outer shield 1 and one or two inner shields 3 among the outer shield 1, two inner shields 3, and virtual paths W7, W8, W9, W10. That is, each of the electrical closed loops LO1, LO2, LO3 necessarily includes a path completed in the outer shield 1 and a path completed in one inner shield 3 or each of the two inner shields 3, and optionally includes at least one of the virtual paths W7, W8, W9, W10. The two virtual paths W7, W8 (or W9, W10) connect the outer shield 1 and the two tip regions r1 of the inner shield 3, respectively, by the shortest distance L1. Each of the electrical closed loops LO1, LO2, LO3 surrounds at least one terminal 4. Each of the electrical closed loops LO1, LO2, and LO3 does not surround the other electrical closed loops. The other electrical closed loops include at least the outer shield 1 and one or two inner shields 3 among the outer shield 1, the two inner shields 3, and the virtual paths W7, W8, W9, and W10. The electrical closed loop LO1 does not surround the electrical closed loops LO2 and LO3, the electrical closed loop LO2 does not surround the electrical closed loops LO1 and LO3, and the electrical closed loop LO3 does not surround the electrical closed loops LO1 and LO2.

[0089] In this disclosure, when one electrical closed loop (hereinafter referred to as a first closed loop) is said to surround another electrical closed loop (hereinafter referred to as a second closed loop), a portion of the first closed loop and a portion of the second closed loop may overlap.

[0090] The longest loop length among the electrical closed loops LO1, LO2, and LO3 is shorter than the wavelength corresponding to the maximum frequency of the transmission signal flowing through the terminal 4. This reduces the possibility of resonance of the transmission signal. More specifically, the maximum frequency is the maximum frequency of the transmission signal flowing through the high-frequency terminal 4T. That is, in this embodiment, the maximum frequency is determined according to the specifications of the high-frequency terminal 4T.

[0091] Incidentally, if not limited to within a plane perpendicular to the vertical direction (a plane parallel to the paper surface of FIG. 13), electrical closed loops other than the electrical closed loops LO1, LO2, and LO3 are also formed in the socket S1. However, since the loop length of all of these is shorter than that of the electrical closed loops LO1, LO2, and LO3, they will not be discussed here.

[0092] Next, the paths W1 to W10 constituting the electrical closed loops LO1, LO2, and LO3 will be described.

[0093] In the socket S1, two inner shields 3 are arranged side by side, front to back. On the left side surface of the outer shield 1, there is a region r2 facing the left tip region r1 of the front inner shield 3, and a region r3 facing the left tip region r1 of the rear inner shield 3. On the right side surface of the outer shield 1, there is a region r4 facing the right tip region r1 of the front inner shield 3, and a region r5 facing the right tip region r1 of the rear inner shield 3.

[0094] Path W1 is included in the front region of the outer shield 1, and connects regions r4 and r2 along the outer shield 1. Path W2 runs along the left side surface of the outer shield 1, connecting regions r2 and r3.

[0095] Path W3 is included in the rear region of the outer shield 1, and connects regions r3 and r5 along the outer shield 1. Path W4 runs along the right side surface of the outer shield 1, connecting regions r5 and r4.

[0096] A path W5 connects the two tip regions r1 of the upper inner shield 3. A path W6 connects the two tip regions r1 of the lower inner shield 3.

[0097] Path W7 connects, by the shortest distance L1, region r2 of the outer shield 1 and the left tip region r1 of the front inner shield 3. Path W8 connects, by the shortest distance L1, region r4 of the outer shield 1 and the right tip region r1 of the front inner shield 3.

[0098] Path W9 connects, via the shortest distance L1, region r3 of the outer shield 1 and the left tip region r1 of the rear inner shield 3. Path W10 connects, via the shortest distance L1, region r5 of the outer shield 1 and the right tip region r1 of the rear inner shield 3.

[0099] The electrical closed loop LO1 is formed by paths W1, W7, W5, and W8. The electrical closed loop LO2 is formed by paths W2, W9, W6, W10, W4, W8, W5, and W7. The electrical closed loop LO3 is formed by paths W3, W10, W6, and W9.

[0100] As described above, in the present disclosure, when it is said that a certain electrical closed loop (first closed loop) surrounds another electrical closed loop (second closed loop), a part of the first closed loop may overlap a part of the second closed loop. For example, in Fig. 13, the first closed loop formed by paths W4, W1, W2, W9, W6, and W10 and the electrical closed loop LO1 as the second closed loop overlap at the path W1, and the first closed loop surrounds the second closed loop.

[0101] In this embodiment, the loop length of the electrical closed loop LO2 is the longest among the electrical closed loops LO1, LO2, and LO3. An example of the longest loop length is about 6 to 7 mm.

[0102] If the maximum frequency fMAX of the transmission signal flowing through terminal 4 is 10 GHz (1010 Hz), then the wavelength λ corresponding to the maximum frequency fMAX is λ = 3 × 108 / fMAX = 0.03 [m] = 30 [mm]. If the longest loop length is 6 to 7 [mm], the longest loop length satisfies the condition that it is shorter than the wavelength λ corresponding to the maximum frequency fMAX.

[0103] Furthermore, the outer shield 1 forms an electrical closed loop LO4 surrounding the terminal 4 without depending on the inner shield 3. The electrical closed loop LO4 is formed by paths W1, W2, W3, and W4. That is, of the outer shield 1, a cylindrical portion 10 (see FIG. 4) that is continuous in the circumferential direction forms the electrical closed loop LO4. The electrical closed loop LO4 surrounds the electrical closed loops LO1, LO2, and LO3.

[0104] Here, the outer shield 1 is formed so as to have no gaps in the circumferential direction of the cylindrical portion 10, and therefore constitutes an electrical closed loop LO4 by itself. However, the outer shield 1 may also constitute an electrical closed loop LO4 together with the conductors 170 and / or 180 of the circuit board 150. In other words, when a gap is formed in the outer shield 1, a path connecting both ends of the gap may be formed by the conductors 170 and / or 180, and the electrical closed loop LO4 may include this path. Here, the conductors 170 and / or 180 do not need to be included in the configuration of the socket S1.

[0105] (2.2) Header structure Next, the configuration of the header H1 according to this embodiment will be described. Among the configuration of the header H1, the description of the configuration that is similar to the configuration of the socket S1 will be omitted as appropriate.

[0106] The header H1 is two-fold symmetrical with respect to an axis passing through the center of the header H1 and extending in the up-down direction. As shown in FIG. 5, the header H1 includes an outer shield 5, a housing 6, a plurality (two) of inner shields 7, and a plurality (eight) of terminals 8. The outer shield 5 and each of the plurality of inner shields 7 are electrostatic shields. The outer shield 5 surrounds the plurality of terminals 8. That is, the outer shield 5 is disposed outside the plurality of terminals 8. The plurality of inner shields 7 are disposed inside the outer shield 5. Also, the plurality of inner shields 7 are disposed inside the housing 6.

[0107] A circuit board 550 (see FIG. 9) is mechanically and electrically connected to the header H1. The circuit board 550 has a base material 560 (see FIG. 9) and conductors 570, 580 (see FIG. 9) that are similar in configuration to the base material 160 and conductors 170, 180 of the circuit board 150 connected to the socket S1. The conductor 570 is provided, for example, on substantially the entire surface of the base material 560 on the side to which the header H1 is connected. Also, in FIG. 6, the region where the conductor 580 (solder) is provided is shown by a two-dot chain line.

[0108] (2.2.1) Header housing The housing 6 is a resin molded body. The housing 6 has electrical insulation properties. The housing 6 has a bottom wall 61 and a peripheral wall 62. The bottom wall 61 is formed in a rectangular shape that is longer in the front-rear direction than in the left-right direction in a plan view. The peripheral wall 62 protrudes downward from the outer periphery of one surface (lower surface) in the thickness direction of the bottom wall 61. The left and right side surfaces of the housing 6 have multiple notches 601 (two on the left side surface and two on the right side surface in FIG. 5) that penetrate the bottom wall 61 and the peripheral wall 62 in the up-down direction. The multiple notches 601 are provided at positions facing the board connection portions 83 of the terminals 8 when viewed from the up-down direction (see FIG. 6).

[0109] As shown in FIG. 7, the housing 6 further has two walls 65. Each wall 65 protrudes downward from the bottom wall 61. The wall 65 is shaped like a rectangular parallelepiped with a lower surface curved into a cylindrical side surface (see FIG. 10). The front and rear ends of the wall 65 are connected to the peripheral wall 62. When viewed from the top-bottom direction, the wall 65 is longer in the front-to-rear direction than in the left-to-right direction. In other words, the wall 65 has a thickness in the direction along the third direction (left-to-right direction). The two walls 65 are lined up side by side.

[0110] Each wall portion 65 has a plurality (two) of accommodating portions 68. An extension portion 72 of the inner shield 7 is accommodated in each of the plurality of accommodating portions 68. Each of the plurality of accommodating portions 68 is a through hole provided in the wall portion 65. The accommodating portions 68 penetrate the wall portion 65 in the up-down direction. The accommodating portions 68 also penetrate the bottom wall 61 in the up-down direction. When viewed from the up-down direction, the accommodating portions 68 provided in the wall portion 65 are recesses recessed from the side surface of the wall portion 65 (surface intersecting with the left-right direction).

[0111] Each wall portion 65 has a plurality of (four) terminal holding portions 69. Each terminal holding portion 69 holds one terminal 8. Each of the plurality of terminal holding portions 69 is a recess provided in the wall portion 65.

[0112] The multiple terminals 8 are insert molded into the housing 6. In this embodiment, eight terminals 8 are fixed to the housing 6. The eight terminals 8 of the header H1 correspond one-to-one to the eight terminals 4 of the socket S1. Each terminal 8 is disposed at a position where it is connected to the corresponding terminal 4.

[0113] 5 and 6, the bottom wall 61 has a plurality of (two) storage grooves 613. Each storage groove 613 is a groove provided on the upper surface of the bottom wall 61. The storage groove 613 is longer in the left-right direction than in the front-rear direction. The storage groove 613 stores the base 71 of the inner shield 7.

[0114] 7, the peripheral wall 62 has a plurality (two) of insertion portions 623. Each of the plurality (two) of insertion portions 623 is a recess provided in the bottom surface (lower surface) of the peripheral wall 62. As described later, a shield protrusion 54 that is a part of the outer shield 5 is inserted into each of the plurality (two) of insertion portions 623.

[0115] (2.2.2) Outer Shield of Header The outer shield 5 surrounds the multiple terminals 8 and the multiple inner shields 7. The outer shield 5 contains metal as a main material or a material such as plating that constitutes the surface. Here, as an example, the outer shield 5 is formed using metal as a main material. As shown in FIGS. 5 and 8, the outer shield 5 has an outer peripheral wall 51, multiple (four) top walls 52, multiple (two) shield protrusions 54, and a bottom wall 55.

[0116] The outer peripheral wall 51 has a rectangular cylindrical shape with a square cross section. The outer peripheral wall 51 includes two first outer peripheral walls 511 and two second outer peripheral walls 512. The two first outer peripheral walls 511 are portions of the outer peripheral wall 51 that extend approximately parallel to each other in the front-rear direction and face each other in the left-right direction. The two second outer peripheral walls 512 are portions of the outer peripheral wall 51 that extend approximately parallel to each other in the left-right direction and face each other in the front-rear direction. The two second outer peripheral walls 512 connect the ends of the two first outer peripheral walls 511 to each other.

[0117] The outer shield 5 further has a plurality of protrusions 56 protruding from the outer peripheral wall 51. The multiple protrusions 56 function as contact portions that come into contact with the outer shield 1 of a mating connector (here, socket S1). The outer peripheral wall 51, the top wall 52, and the multiple protrusions 56 form a cylindrical portion 50 that is open at both ends in the first direction (up-down direction). That is, the cylindrical portion 50 includes the outer peripheral wall 51, the top wall 52, and the multiple 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 multiple protrusions 56.

[0118] The outer shield 5 of the connector (here, the header H1) has a side surface (outer peripheral surface 501) along a first direction (up-down direction). The side surface (outer peripheral surface 501) has a convex structure. That is, a structure consisting of a plurality of protrusions 56 corresponds to the convex structure. The outer shield 5 of the connector (here, the header H1) comes into contact with the outer shield 1 of the mating connector (here, the socket S1) at the convex structure (the plurality of protrusions 56). More specifically, the plurality of protrusions 56 come into contact with the inner peripheral surface 103 of the tubular portion 10 of the outer shield 1 (see FIG. 10).

[0119] Compared to a case where there are no multiple protrusions 56 and the outer peripheral surface 501 is flat, even if there is some variation in the dimensions of the outer shields 1, 5, it is possible to press the outer shield 1 into the outer shield 5. This reduces the possibility of poor contact, for example, in which the outer shields 1, 5 come into contact with each other on one side of the left and right (or front and back) and are separated from each other on the other side.

[0120] Three protrusions 56 are provided on each of the two first outer peripheral walls 511. One protrusion 56 is provided on each of the two second outer peripheral walls 512. The multiple protrusions 56 are provided at intervals in the circumferential direction of the cylindrical portion 50. The maximum value of the creepage distances L2 and L3 between the multiple protrusions 56 is equal to or less than ¼ of the wavelength λ corresponding to the maximum frequency of the transmission signal flowing through the terminal 8. This can reduce the possibility of noise leaking from the area between the multiple protrusions 56 (the area of ​​the outer shield 5 that is not electrically connected to the outer shield 1). Here, the creepage distance L2 between the protrusions 56 provided on the first outer peripheral wall 511 and the protrusions 56 provided on the second outer peripheral wall 512 is greater than the creepage distance L3 between the multiple protrusions 56 provided on the first outer peripheral wall 511. That is, the maximum value of the creepage distance between the multiple protrusions 56 is the creepage distance L2. Here, the maximum frequency is, more specifically, the maximum frequency of the transmission signal flowing through 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.

[0121] Each of the multiple (four) top walls 52 has an L-shape when viewed from the top-bottom direction. The multiple (four) top walls 52 are connected to the lower end of the four corners of the outer peripheral wall 51 and extend toward the inside of the outer peripheral wall 51 when viewed from the top-bottom direction.

[0122] The bottom wall 55 has a rectangular frame shape when viewed from the top-bottom direction. 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 from the top-bottom direction. The lower surface of the bottom wall 55 is formed so as to be parallel to a plane including the front-rear and left-right directions.

[0123] The inner peripheral surface of the outer peripheral wall 51 corresponds to an inner peripheral surface 503 of the cylindrical portion 50. The outer shield 5 also has a tip surface 502. The tip surface 502 is provided at one end (lower end) of both ends of the cylindrical portion 50 in the first direction (vertical direction) that is on the mating connector side when the connector (here, the header H1) and the mating connector (here, the socket S1) transition from a non-connected state to a connected state. The tip 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 tip surface 502. Also, the inner edge of the tip surface 502 corresponds to a part of the inner edge of the cylindrical portion 50 at the lower end of the cylindrical portion 50.

[0124] The boundary portion b3 between the tip surface 502 and the outer circumferential surface 501 is an arc-shaped surface when viewed from the front-rear direction (see FIG. 9). Note that the tip surface 502 is defined here as a region of the outer surface of the tubular portion 50 that forms an acute angle with the up-down direction of 0 degrees or more and less than 45 degrees. The outer surface that forms the acute angle of 45 degrees or more is defined as the outer circumferential surface 501. The boundary portion b3 has a predetermined length along the circumferential direction of the tubular portion 10.

[0125] The multiple (two) shield protrusions 54 are provided corresponding to two of the multiple (four) top walls 52. Each shield protrusion 54 protrudes upward from the corresponding top wall 52. The multiple (two) shield protrusions 54 correspond one-to-one to the multiple (two) insertion portions 623 (see FIG. 7) provided in the housing 6. Each shield protrusion 54 is inserted into the corresponding insertion portion 623.

[0126] The outer shield 5 is fixed to the housing 6 by press-fitting. That is, the outer shield 5 is held in the housing 6 by being pressed in one direction (upward) into the housing 6. At this time, the multiple top walls 52 of the outer shield 5 cover at least a part of the peripheral wall 62 of the housing 6. Also, at this time, each shield protrusion 54 is inserted into the corresponding insertion portion 623.

[0127] The entire surface of the outer shield 5 is formed without seams. 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., there are no seams or discontinuities) over the entire circumferential direction of the tubular portion 50.

[0128] 8, the outer peripheral surface 501 includes an outer surface 5110 (including the surface of the first outer peripheral wall 511 and the surface of the protrusion 56) corresponding to each of the two first outer peripheral walls 511, and an outer surface 5120 (including the surface of the second outer peripheral wall 512 and the surface of the protrusion 56) corresponding to each of the two second outer peripheral walls 512. Each of the outer surface 5110 and the outer surface 5120 is seamless. Furthermore, the outer surface 5110 and the outer surface 5120, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the outer peripheral surface 501 is seamless over the entire circumferential direction of the tubular portion 50.

[0129] 8, the inner circumferential surface 503 includes an inner surface 5111 of each of the two first outer circumferential walls 511 and an inner surface 5121 of each of the two second outer circumferential walls 512. Each of the inner surfaces 5111 and 5121 is seamless. Furthermore, the inner surfaces 5111 and 5121, which are two surfaces whose normal directions are different from each other, are seamlessly connected. In this way, the inner circumferential surface 503 is seamless over the entire circumferential direction of the tubular portion 10.

[0130] In addition, there is no boundary b3 between the outer peripheral surface 501 and the tip surface 502. For example, in the upper right corner of the page of Fig. 8 (a corner portion of the outer shield 5), the outer surface 5110, the outer surface 5120, and the tip surface 502, which are three surfaces having different normal directions, are seamlessly connected.

[0131] (2.2.3) Inner shield of header In this embodiment, the two inner shields 7 have the same shape. The inner shields 7 contain metal as a main material or a material such as plating that constitutes the surface. Here, as an example, the inner shield 7 is formed with metal as a main material. As shown in FIG. 9, the inner shield 7 has a base 71 and multiple (two) extensions 72 (first extensions).

[0132] The base 71 has a length in the direction along the third direction (left-right direction). The shape of the base 71 is plate-like. When viewed in the thickness direction (front-back direction) of the base 71, the base 71 is longer in the left-right direction than in the up-down direction. The base 71 is accommodated in an accommodating groove 613 provided in the bottom wall 61 of the housing 6.

[0133] The multiple extensions 72 protrude downward from the base 71. That is, the multiple extensions 72 protrude along the first direction (vertical direction) in a direction toward the mating connector when the connector (here, the header H1) and the mating connector (here, the socket S1) transition from a non-connected state to a connected state. Each extension 72 is shaped like a rectangular plate. When viewed from the thickness direction (front-back direction) of each extension 72, each extension 72 is longer in the vertical direction than in the horizontal direction. The thickness direction of each extension 72 may be the horizontal direction.

[0134] The extension 72 includes a contact portion 720 (contact surface) that comes into contact with the inner shield 3 of the mating connector (socket S1). The contact portion 720 is provided on a surface of the extension 72 that is along the length direction of the extension 72 (here, the left or right surface). The contact portions 720 of the two extensions 72 face in opposite directions (rightward and leftward).

[0135] The header H1 has two extensions 72 on each of the two inner shields 7. That is, the header H1 has a total of four extensions 72. The four accommodation portions 68 (see FIG. 7) provided in the housing 6 correspond one-to-one to the four extensions 72. Each extension 72 is accommodated in the corresponding accommodation portion 68.

[0136] The inner shield 7 is fixed to the housing 6 by press-fitting. That is, the inner shield 7 is held in the housing 6 by being pressed in one direction (downward) into the housing 6. At this time, each extension 72 is housed in the corresponding housing portion 68. Here, the housing space for each of the two extensions 72 in the shield holding portion (housing portion 68) is larger than each of the two extensions 72.

[0137] As shown in FIG. 9, the base 71 of the inner shield 7 is located at the upper end of the header H1. Here, the outer shield 5 has a first end e5 and a second end e6. The first end e5 is an end (lower end) on the mating connector side when the connector (here, the header H1) and the mating connector (here, the socket S1) transition from a non-connected state to a connected state. The second end e6 is an end (upper end) opposite to the first end e5. Here, the second end e6 is an area that covers the entire circumferential circumference of the bottom wall 55 of the outer shield 5. The outer shield 5 faces the two tip regions r7 of the inner shield 7 in an area including the second end e6.

[0138] The outer shield 5 faces at least one of the two tip regions r7 across a gap g7 in a region including the second end e6. As shown in FIG. 9, the outer shield 5 is electrically connected to conductors 570 and 580 of the circuit board 550. The conductors 570 and 580 are provided so as to bridge the second end e6 of the outer shield 5 across the two tip regions r7 of the inner shield 7, respectively. That is, the outer shield 5 is electrically connected to the inner shield 7 through the conductors 570 and 580. On the other hand, in a state in which the circuit board 550 does not exist, the outer shield 5 is electrically insulated from at least one of the two tip regions r7 (both in this embodiment) through the gap g7. The shortest distance L7 between the outer shield 5 and at least one of the two tip regions r7 in the gap g7 is 0.01 mm or more and 0.1 mm or less.

[0139] The inner shield 7 has a first end e7 and a second end e8. The first end e7 is an end (lower end) that is on the mating connector side when the connector (here, the header H1) and the mating connector (here, the socket S1) transition from a non-connected state to a connected state. The second end e8 is an end (upper end) opposite to the first end e7. The inner shield 7 has a connection surface 710 (upper surface) at the second end e8 that is electrically connected to the circuit board 550. The connection surface 710 is planar and continuous across the two tip regions r7. More specifically, the connection surface 710 is a rectangular plane that connects the two tip regions r7.

[0140] (2.2.4) Header terminals 6 and 7, the multiple (eight) terminals 8 include multiple (six) low-frequency terminals 8P and multiple (two) high-frequency terminals 8T. The arrangement of the multiple terminals 8 is similar to the arrangement of the multiple terminals 4 of the socket S1. In other words, the contents described in "(2.1.4.1) Arrangement" also apply to the multiple terminals 8.

[0141] The terminals 8 have the same shape. Each terminal 8 is formed, for example, by punching and bending a metal plate. As shown in FIG. 11, each terminal 8 has a (first) contact portion 81, a roll-up piece 82, a board connection portion 83, and a (second) contact portion 84.

[0142] The board connection portion 83 is electrically connected to, for example, the conductor 580 (solder) of the circuit board 550. That is, the board connection portion 83 is joined to the circuit board 550 by a joining means such as soldering. This electrically and mechanically connects the circuit board 550 and the terminal 8. As shown in FIG. 6, the board connection portion 83 is surrounded by the outer shield 5 when viewed from the first direction (the vertical direction). Furthermore, at least a part of the board connection portion 83 and at least a part of the outer shield 5 exist on a plane perpendicular to the vertical direction.

[0143] The contact portion 81 and the contact portion 84 have a length in the up-down direction. The contact portion 81 is a portion that contacts the contact portion 41 of the terminal 4 of the socket S1, and the contact portion 84 is a portion that contacts the contact portion 46 of the terminal 4 of the socket S1. The winding piece 82 is formed in a U-shape that is open upward. The winding piece 82 connects the lower end of the contact portion 81 to the lower end of the contact portion 84. The board connection portion 83 is a portion that protrudes from the upper end of the contact portion 81.

[0144] When the terminal 8 is held in the housing 6, at least a part of the contact portion 81 and the contact portion 84 is exposed when viewed from below. The contact portion 81 and the contact portion 84 come into contact with a corresponding terminal 4 among a plurality of terminals 4 (mating terminals) of the socket S1 (mating connector) and are electrically connected to the terminal 4 (see FIG. 12).

[0145] The terminal 8 further has a force sense portion 85. The force sense portion 85 generates a clicking sensation when the terminal 8 comes into contact with the terminal 4 (mating terminal). The force sense portion 85 is a protrusion protruding from the contact portion 81. When the force sense portion 85 (protrusion) rides over the force sense portion 47 of the terminal 4, a clicking sensation is generated.

[0146] The contact portion 84 has a recess 840 on the surface that comes into contact with the contact portion 46. That is, the contact portion 46 is inserted into the recess 840. Here, the contact portion 46 comes into contact with the side surface of the recess 840.

[0147] As shown in FIG. 7, the abutment portion 720 of the inner shield 7 and the contact portion 81 of at least one of the multiple terminals 8 are aligned in the second direction (front-rear direction).

[0148] (2.2.5) Header side circuit board The header H1 is electrically connected to a conductor 580 (solder) of the circuit board 550. In Fig. 6, the area on the top surface of the header H1 where the conductor 580 is provided is illustrated by a two-dot chain line. The arrangement and electrical connection relationship of the conductors 570, 580, outer shield 5, multiple inner shields 7, and multiple terminals 8 of the circuit board 550 are similar to the arrangement and electrical connection relationship of the conductors 170, 180, outer shield 1, multiple inner shields 3, and multiple terminals 4 of the circuit board 150 corresponding to the socket S1.

[0149] (2.2.6) Header Electrical Closed Loop The arrangement of the outer shield 5, the multiple (two) inner shields 7, and the multiple (eight) terminals 8 of the header H1 is similar to the arrangement of the outer shield 1, the multiple (two) inner shields 3, and the multiple (eight) terminals 4 of the socket S1 shown in FIG. 13. Therefore, in the header H1, at least multiple (three) electrical closed loops LO1, LO2, LO3 are formed, similar to the socket S1. The details of the electrical closed loops LO1, LO2, LO3 of the header H1 are similar to the details of the electrical closed loops LO1, LO2, LO3 of the socket S1. Also, like the outer shield 1, the outer shield 5 forms an electrical closed loop LO4 surrounding the terminal 8 without relying on the inner shield 7.

[0150] Here, the outer shield 5 is formed so as to have no gaps in the circumferential direction of the cylindrical portion 50, and therefore constitutes an electrical closed loop LO4 by itself. However, the outer shield 5 may constitute an electrical closed loop LO4 together with the conductors 570 and / or 580 of the circuit board 550. In other words, when a gap is formed in the outer shield 5, a path connecting both ends of the gap may be formed by the conductors 570 and / or 580, and the electrical closed loop LO4 may include this path. Here, the conductors 570 and / or 580 do not need to be included in the configuration of the header H1.

[0151] (3) Assembly process Next, an example of a process for assembling connector device 100 by connecting socket S1 and header H1 will be described with reference to FIGS.

[0152] The socket S1 is mechanically and electrically connected to the circuit board 150. The header H1 is mechanically and electrically connected to the circuit board 550. In this state, as shown in FIG. 9 and FIG. 11, the socket S1 is disposed below the header H1. Then, at least one of the socket S1 moving upward and the header H1 moving downward is performed. As a result, as shown in FIG. 10 and FIG. 12, the socket S1 and the header H1 are mechanically connected. Also, as shown in FIG. 10, the inner shield 3 of the socket S1 and the inner shield 7 of the header H1 come into contact with each other and are electrically connected. Also, as shown in FIG. 12, the multiple terminals 4 of the socket S1 and the multiple terminals 8 of the header H1 come into contact with each other and are electrically connected. Also, as shown in FIG. 10 and FIG. 12, the outer shield 1 of the socket S1 and the outer shield 5 of the header H1 come into contact with each other and are electrically connected. Also, as shown in FIG. 10, two walls 65 of the housing 6 of the header H1 are inserted between the first wall 25 and the second wall 26 of the housing 2 of the socket S1, and between the second wall 26 and the third wall 27.

[0153] When the socket S1 and the header H1 (connector and mating connector) transition from a non-connected state to a connected state, the components of the socket S1 and the header H1 come into contact with each other in the following order.

[0154] First, the socket S1 and the header H1 contact each other at the outer shields 1, 5. That is, a region near the upper end of the inner circumferential surface 103 of the tubular portion 10 of the outer shield 1 contacts a region near the lower end of the outer circumferential surface 501 of the tubular portion 50 of the outer shield 5.

[0155] Next, the socket S1 and the header H1 come into contact with each other at the terminals 4, 8. That is, at least one of the contact portion 41 and the contact portion 81 come into contact with each other and the contact portion 46 and the contact portion 84 come into contact with each other.

[0156] Next, the socket S1 and the header H1 come into contact with each other at the inner shields 3, 7. That is, the abutment portion 332 of the inner shield 3 and the abutment portion 720 of the inner shield 7 come into contact with each other.

[0157] Next, the force-sense portion 47 (or 85) of the connector (socket S1 or header H1) comes into contact with the mating terminal (terminal 8 or 4). That is, at least one of the force-sense portion 47 comes into contact with the contact portion 81 of the terminal 8 and the force-sense portion 85 comes into contact with the contact portion 41 of the terminal 4. Then, a clicking sensation is generated by the force-sense portions 47, 85.

[0158] Next, the outer shield 5 of the connector (here, the header H1) contacts the outer shield 1 of the mating connector (here, the 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 tubular portion 10 of the outer shield 1 (see FIG. 10). More specifically, the multiple protrusions 56 first contact the region near the upper end of the inner circumferential surface 103. Then, due to the contact pressure between the multiple protrusions 56 and the inner circumferential surface 103, the multiple protrusions 56 move further downward while the outer shield 1 is elastically deformed so that the inner circumferential wall 13 of the outer shield 1 moves toward the outside (the outer circumferential wall 11 side). Finally, as shown in FIG. 10, the multiple protrusions 56 contact the region of the inner circumferential surface 103 along the up-down direction. With the above, the connection between the socket S1 and the header H1 is completed.

[0159] In this way, a clicking sensation occurs at the terminals 4, 8 before the contact pressure and frictional force between the outer shields 1, 5 increase due to the contact of the multiple protrusions 56 with the outer shield 1. Therefore, the click sensation is more easily perceived by the worker than when the click sensation occurs after the multiple protrusions 56 come into contact with the outer shield 1. In other words, it is possible to prevent the click sensation from becoming difficult to perceive due to frictional force. In addition, the positional relationship between the outer shields 1, 5, which is fixed by the contact of the multiple protrusions 56 with the outer shield 1, is not changed in the subsequent process, so that the positioning accuracy can be improved. This ensures a contact area between the outer shields 1, 5.

[0160] (4) Noise level 14 represents the analysis results of the radiation noise of the connector device 100 of the embodiment, and the dashed line in Fig. 14 represents the analysis results of the radiation noise of the connector device of the comparative example. The horizontal axis represents the frequency (unit: [GHz]), and the vertical axis represents the noise level (unit: [dBμV / m]). .

[0161] The connector device of the comparative example differs from the connector device 100 of the embodiment in that each of the outer shields 1, 5 is formed by bending a metal plate, and the other configurations are the same as those of the connector device 100 of the embodiment. Therefore, for example, the outer peripheral surface and inner peripheral surface of the cylindrical portion 10 (50) of each of the outer shields 1, 5 of the connector device of the comparative example have a seam or a gap in the circumferential direction of the cylindrical portion 10 (50). In contrast, in the connector device 100 of the embodiment, each of the outer shields 1, 5 is formed by drawing a metal. Therefore, the outer peripheral surface and inner peripheral surface of the cylindrical portion 10 (50) of each of the outer shields 1, 5 are formed seamlessly (i.e., without seams or gaps) over the entire circumference of the cylindrical portion 10 (50) in the circumferential direction.

[0162] 14, at each frequency, the connector device 100 of the embodiment has a lower noise level than the connector device of the comparative example. That is, compared to the comparative example, in the embodiment, the joints of the outer shields 1, 5 are removed, so that not only is the effect of suppressing the influence of resonance suppressed, but also the effect of reducing noise radiated from the joints can be obtained.

[0163] (Variation 1) The socket S2 and the header H2 according to the first modification will be described below with reference to Figs. 15 to 18. The same components as those in the embodiment are denoted by the same reference numerals and will not be described. In Figs. 15 and 17, the regions where the conductors 180 and 580 (solder) are provided are indicated by two-dot chain lines.

[0164] 15 and 16, the socket S2 has only one inner shield 3. Also, the socket S2 has only two terminals 4. Accordingly, the shapes of the outer shield 1A and the housing 2A are different from the shapes of the outer shield 1 and the housing 2 of the embodiment. This will be described in more detail below.

[0165] The schematic shape of the housing 2A is the same as that of the housing 2 in the embodiment, except that the area where the six low-frequency terminals 4P are provided is omitted. The schematic shape of the outer shield 1A is the same as that of the outer shield 1 in the embodiment, except that the area where the six low-frequency terminals 4P are provided is omitted.

[0166] Each of the first wall portion 25, the second wall portion 26, and the third wall portion 27 of the housing 2 has one receiving portion 28. The (three) receiving portions 28 receive the three extension portions 32 of the inner shield 3.

[0167] Moreover, each of the first wall portion 25 and the third wall portion 27 has one terminal holding portion 29. The second wall portion 26 has two terminal holding portions 29. One of the two terminals 4 is held by the terminal holding portion 29 of the first wall portion 25 and one of the terminal holding portions 29 of the second wall portion 26. The other of the two terminals 4 is held by the terminal holding portion 29 of the third wall portion 27 and the other terminal holding portion 29 of the second wall portion 26.

[0168] Here, the two terminals 4 are high-frequency terminals 4T, but are not limited to this, and at least one of the two terminals 4 may be a low-frequency terminal 4P.

[0169] The two high-frequency terminals 4T are disposed on both sides (front and rear) of the inner shield 3. Therefore, similar to the embodiment, it is possible to reduce the possibility of noise propagation between the two high-frequency terminals 4T.

[0170] 17 and 18, the header H2 has only one inner shield 7. Also, the header H2 has only two terminals 8. Accordingly, the shapes of the outer shield 5A and the housing 6A are different from those of the outer shield 5 and the housing 6 of the embodiment. This will be described in more detail below.

[0171] The schematic shape of the housing 6A is the same as that of the housing 6 in the embodiment, except that the area where the six low-frequency terminals 8P are provided is omitted. The schematic shape of the outer shield 5A is the same as that of the outer shield 5 in the embodiment, except that the area where the six low-frequency terminals 8P are provided is omitted.

[0172] Each of the two walls 65 of the housing 6 has one receiving portion 68. In these (two) receiving portions 68, two extensions 72 of the inner shield 7 are received.

[0173] Each of the two wall portions 65 has one terminal holding portion 69. Each terminal holding portion 69 holds a terminal 8.

[0174] Here, the two terminals 8 are high-frequency terminals 8T, but are not limited to this, and at least one of the two terminals 8 may be a low-frequency terminal 8P.

[0175] The two high-frequency terminals 8T are disposed on both sides (front and rear) of the inner shield 7. Therefore, similar to the embodiment, it is possible to reduce the possibility of noise propagation between the two high-frequency terminals 8T.

[0176] (Variation 2) The socket S1 and the header H1 according to the second modification will be described below with reference to Figs. 19 and 20. The same components as those in the embodiment are denoted by the same reference numerals and will not be described. Note that Figs. 19 and 20 only show two high-frequency terminals 4T and two high-frequency terminals 8T of the socket S1 and the header H1.

[0177] In the present modified example 2, the low frequency terminal 4P and the high frequency terminal 4T in the socket S1 have different shapes. Also, the low frequency terminal 8P and the high frequency terminal 8T in the header H1 have different shapes.

[0178] That is, the socket S1 of the present modified example 2 has a plurality of terminals 4. The header H1 has a plurality of terminals 8. The plurality of terminals 4 (or 8) includes a first terminal (low-frequency terminal 4P or 8P) and a second terminal (high-frequency terminal 4T or 8T). The second terminal has a shape different from that of the first terminal. An inner shield 3 (or 7) is disposed between the first terminal and the second terminal (see FIG. 13).

[0179] As an example, the low frequency terminal 4P has a shape similar to that of the low frequency terminal 4P in the embodiment. Also, as an example, the low frequency terminal 8P has a shape similar to that of the low frequency terminal 8P in the embodiment.

[0180] 19, the radio frequency terminal 4T of the present modified example 2 has, as an example, two contact portions 41, a base portion 42, and a board connection portion 45. The radio frequency terminal 4T is formed, for example, by subjecting a metal plate to punching, bending, or the like.

[0181] The base 42 is formed in a U-shape that is open upward. The board connection portion 45 is connected to a lower end portion of the base 42. One contact portion 41 protrudes in the front-rear direction from the left end of the base 42, and the other contact portion 41 protrudes in the front-rear direction from the right end of the base 42.

[0182] 19, the high-frequency terminal 8T has, as an example, two contact portions 81, a base portion 86, and a board connection portion 83. The high-frequency terminal 8T is formed, for example, by subjecting a metal plate to punching, bending, or the like.

[0183] The base 86 is formed in a U-shape that is open downward. The board connection portion 83 is connected to an upper end portion of the base 86. One contact portion 81 protrudes to the left from the left end of the base 86, and the other contact portion 81 protrudes to the right from the right end of the base 86.

[0184] In the process of connecting the socket S1 and the header H1, each radio frequency terminal 4T is connected to a corresponding radio frequency terminal 8T, as shown in Fig. 20. That is, the radio frequency terminal 8T is inserted between two contact portions 41 of the radio frequency terminal 4T. As a result, each of the two contact portions 41 comes into contact with the corresponding contact portion 81. At this time, the space between the two contact portions 41 is expanded in the left-right direction.

[0185] The terminals 4, 8 may be shaped as follows. Since the low-frequency terminal 4P (8P) may be connected to a power supply wiring and ground, it may be made wider than the high-frequency terminal 4T (8T) to reduce resistance. Also, to reduce resistance at the low-frequency terminals 4P, 8P, the contact area between the low-frequency terminal 4P and the low-frequency terminal 8P may be made larger than the contact area between the high-frequency terminal 4T and the high-frequency terminal 8T. Also, since the high-frequency terminal 4T (8T) passes high-speed signals, it may be shaped so that its characteristic impedance matches the characteristic impedance of a signal line formed on the circuit board 150 (550).

[0186] Furthermore, in only one of the socket S1 and the header H1, the low frequency terminal 4P (8P) and the high frequency terminal 4T (8T) may have different shapes.

[0187] (Other Modifications of the Embodiments) Other variations of the embodiment are listed below. The following variations may be implemented in appropriate combination. The following variations may also be implemented in appropriate combination with the above-mentioned variation 1.

[0188] The outer shield 1 (5) and the inner shield 3 (7) are not limited to being electrically connected to each other via the conductor 180 (580) of the circuit board 150 (550), but may be electrically connected to each other via another conductive member.

[0189] At least one of the outer shield 1 (5), the multiple inner shields 3 (7), and the multiple terminals 4 (8) may contact the conductor 170 (570) and thereby be electrically connected to the conductor 170 (570).

[0190] As shown in FIG. 21, in the socket S1, at least one of the two tip regions r1 of the inner shield 3 (both in FIG. 21) may be directly coupled to the outer shield 1. Similarly, in the header H1, at least one of the two tip regions r7 of the inner shield 7 may be directly coupled to the outer shield 5. For example, the length of the inner shield 3 (7) may be extended compared to the embodiment, and the inner shield 3 (7) may be coupled to the outer shield 1 (5) by means of welding, press-fitting, crimping, or the like. Alternatively, a portion of the inner shield 3 (7) including the tip region r1 (r7) and at least a part of the outer shield 1 (5) may be formed from a single member. The inner shield 3 (7) and the outer shield 1 (5) may be seamlessly connected to each other.

[0191] The extension 32 (or 72) is not limited to protruding in the up-down direction from the base 31 (or 71). For example, the extension 32 (or 72) may protrude in the front-rear direction from the base 31 (or 71).

[0192] The number of each component 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) of the inner shield 3 (7) can be changed as appropriate. Also, the number of terminals 4 (8) of each connector (socket S1 and header H1) can be changed as appropriate. Also, each connector may have only low-frequency terminals 4P (8P) as terminals 4 (8), or only high-frequency terminals 4T (8T).

[0193] In the embodiments, a portion formed as a recess or a depression may be replaced with a through hole, and conversely, a portion formed as a through hole may be replaced with a recess or a depression.

[0194] In the embodiment, the portions joined by press fitting may be joined by insert molding. Conversely, in the embodiment, the portions joined by insert molding may be joined by press fitting. Also, instead of press fitting or insert molding, another joining method, for example, adhesion, welding, crimping, etc., may be adopted.

[0195] The outer shields 1, 5 may be formed, for example, by molding instead of drawing, whereby at least a part of the surface of the outer shields 1, 5 (for example, the entire outer circumferential surface 101, 501) may be formed seamlessly. Also, at least a part of the surface of the outer shields 1, 5 may be formed seamlessly by, for example, welding.

[0196] The multiple protrusions 56 of the outer shield 5 may be provided on the inner circumferential surface 503 of the tubular portion 50 instead of on the outer circumferential surface 501 .

[0197] A part of the configuration of the socket S1 in the embodiment may be applied to the header H1 as appropriate. Conversely, a part of the configuration of the header H1 in the embodiment may be applied to the socket S1 as appropriate. For example, the multiple protrusions 56 may be provided on both of the outer shields 1 and 5, or may be provided only on the outer shield 1 of the outer shields 1 and 5.

[0198] (summary) The above-described embodiments and the like disclose the following aspects.

[0199] The connector (socket S1, S2 or header H1, H2) according to the first embodiment includes an outer shield (1, 1A or 5, 5A), a terminal (4 or 8), a housing (2, 2A or 6, 6A), and an inner shield (3 or 7). The terminal (4 or 8) is surrounded by the outer shield (1, 1A or 5, 5A). The terminal (4 or 8) is electrically connected to a mating terminal of a mating connector. The housing (2, 2A or 6, 6A) is fixed relative to the outer shield (1, 1A or 5, 5A). The housing (2, 2A or 6, 6A) holds the terminal (4 or 8). The inner shield (3 or 7) is surrounded by the outer shield (1, 1A or 5, 5A). The inner shield (3 or 7) includes two tip regions (r1 or r7). The two tip regions (r1 or r7) consist of a first tip region facing or directly coupled to the outer shield (1, 1A or 5, 5A), and a second tip region facing or directly coupled to the outer shield (1, 1A or 5, 5A). Among the multiple electrical closed loops described below, the longest loop length of the electrical closed loop (LO1, LO2, LO3) that does not surround other electrical closed loops is shorter than the wavelength corresponding to the maximum frequency of the transmission signal flowing through the terminal (4 or 8). Each of the multiple electrical closed loops includes at least the outer shield (1, 1A or 5, 5A) and the inner shield (3 or 7), and two virtual paths (W7, W8; W9, W10) connecting the outer shield (1, 1A or 5, 5A) and the two tip regions (r1 or r7) by the shortest distance (L1 or L7), respectively, and surrounds the terminal (4 or 8).

[0200] According to the above configuration, it is possible to reduce the possibility that resonance of the transmission signal occurs in the electrical closed loop.

[0201] In addition, in the connector (socket S1, S2 or header H1, H2) of the second aspect, in the first aspect, the outer shield (1, 1A or 5, 5A) forms an electrically closed loop (LO4) surrounding the terminal (4 or 8) without relying on the inner shield (3 or 7).

[0202] According to the above configuration, it is possible to reduce the possibility of noise propagation between the inside and outside of the electrical closed loop (LO4) formed by the outer shield (1, 1A or 5, 5A) without relying on the inner shield (3 or 7).

[0203] In the third embodiment (socket S1, S2 or header H1, H2), in the first or second embodiment, when the circuit board (150 or 550) is not present, the outer shield (1, 1A or 5, 5A) is electrically insulated from at least one of the two tip regions (r1 or r7) via a gap (g1 or g7). The circuit board (150 or 550) is electrically connected to the outer shield (1, 1A or 5, 5A).

[0204] According to the above configuration, the dimensional tolerances of each of the outer shield (1, 1A or 5, 5A) and the inner shield (3 or 7) are improved compared to when the outer shield (1, 1A or 5, 5A) is in contact with the two tip regions (r1 or r7).

[0205] In addition, in the connector (socket S1, S2 or header H1, H2) of the fourth aspect, in the third aspect, the shortest distance (L1 or L7) between the outer shield (1, 1A or 5, 5A) in the gap (g1 or g7) and at least one of the two tip regions (r1 or r7) is 0.01 mm or more and 0.1 mm or less.

[0206] According to the above configuration, the dimensional tolerance of each of the outer shield (1, 1A or 5, 5A) and the inner shield (3 or 7) is improved compared to when the outer shield (1, 1A or 5, 5A) and the two tip regions (r1 or r7) are in contact with each other. Also, compared to when the shortest distance (L1 or L7) is even larger, the propagation of noise through the gap between the inner shield (3 or 7) and the outer shield (1 or 5) (in the embodiment, the propagation of noise between the high frequency terminal 4T or 8T and the low frequency terminal 4P or 8P) is also reduced.

[0207] In addition, in a connector (socket S1, S2 or header H1, H2) according to a fifth aspect, in any one of the first to fourth aspects, at least one of the two tip regions (r1 or r7) is directly coupled to the outer shield (1, 1A or 5, 5A).

[0208] According to the above configuration, the outer shield (1, 1A or 5, 5A) and the inner shield (3 or 7) can be electrically connected.

[0209] In addition, in a connector (socket S1, S2 or header H1, H2) according to a sixth aspect, in any one of the first to fifth aspects, the outer shield (1, 1A or 5, 5A) has a first end (e1 or e5) and a second end (e2 or e6) opposite the first end (e1 or e5). The first end (e1 or e5) is an end that becomes the mating connector side when the connector and the mating connector transition from a non-connected state to a connected state. The outer shield (1, 1A or 5, 5A) faces or is directly connected to the two tip regions (r1 or r7) in a region including the second end (e2 or e6).

[0210] According to the above configuration, at least a part of the inner shield (3 or 7) is provided on the second end (e2 or e6) side, so that it is possible to reduce the possibility of noise propagation on the second end (e2 or e6) side.

[0211] Furthermore, the connector (socket S1, S2 or header H1, H2) according to a seventh aspect is any one of the first to sixth aspects and includes a plurality of terminals 4 (or 8). The plurality of terminals 4 (or 8) includes two terminals 4 (or 8) arranged on both sides of the inner shield (3 or 7).

[0212] According to the above configuration, it is possible to reduce the possibility of noise propagation between the two terminals (4 or 8).

[0213] In addition, in the connector according to the eighth aspect (the socket S1, S2 or the header H1, H2), in the seventh aspect, the two terminals (4 or 8) are electrically connected to the signal line.

[0214] According to the above configuration, the possibility of noise being introduced into the signal can be reduced.

[0215] In addition, in the connector (socket S1, S2 or header H1, H2) of the ninth aspect, in any one of the first to eighth aspects, the connector is provided with a terminal (4P or 8P) having the same potential as the inner shield (3 or 7) as the terminal (4 or 8) or as a terminal separate from the terminal (4 or 8).

[0216] According to the above configuration, noise can be caused to flow from the terminal (4 or 8) to the inner shield (3 or 7) or to an electric path having the same potential as the inner shield (3 or 7).

[0217] Furthermore, the connector (socket S1, S2 or header H1, H2) according to a tenth aspect is any one of the first to ninth aspects and includes a plurality of terminals (4 or 8). The plurality of 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 second terminal has a shape different from that of the first terminal. An inner shield (3 or 7) is disposed between the first terminal and the second terminal.

[0218] According to the above configuration, each terminal (4 or 8) can be shaped according to its intended use, and the possibility of noise propagation between terminals (4 or 8) having different uses can be reduced.

[0219] In addition, in a connector (header H1, H2) according to an eleventh aspect, in any one of the first to tenth aspects, the connector and the mating connector (socket S1, S2) are connected to each other by at least one of them moving toward the other in a predetermined direction. The outer shield (5, 5A) of the connector has a side (outer peripheral surface 501) along the predetermined direction. The side has a convex structure (multiple protrusions 56). The outer shield (5, 5A) of the connector contacts the outer shield (1, 1A) of the mating connector in the convex structure.

[0220] With the above configuration, even if there is some variation in the dimensions of the outer shield (5, 5A) of the connector and the outer shield (1, 1A) of the mating connector, it is possible to press one outer shield into the other outer shield. In other words, the dimensional tolerances of the outer shield (5, 5A) of the connector and the outer shield (1, 1A) of the mating connector are improved.

[0221] In the connector (headers H1, H2) according to the twelfth aspect, in the eleventh aspect, the terminal (8) has a force-sense portion (85). The force-sense portion (85) produces a clicking sensation when the terminal (8) comes into contact with the mating terminal (4). When the connector and the mating connector (sockets S1, S2) transition from a non-connected state to a connected state, the connector and the mating connector come into contact with each other in the following order: they come into contact with each other at the outer shields (1, 1A, 5, 5A), then they come into contact with each other at the terminals (4, 8), then they come into contact with each other at the inner shields (3, 7), then the force-sense portion (85) of the connector comes into contact with the mating terminal (4), and then the outer shield (5, 5A) of the connector comes into contact with the outer shield (1, 1A) of the mating connector at the convex structure (multiple protrusions 56).

[0222] According to the above configuration, the accuracy of positioning between the connector and the mating connector can be improved.

[0223] In addition, in the connector (socket S1, S2 or header H1, H2) according to a thirteenth aspect, in any one of the first to twelfth aspects, the inner shield (3 or 7) has a first end (e3 or e7) and a second end (e4 or e8) opposite to the first end (e3 or e7). The first end (e3 or e7) is an end that is on the mating connector side when the connector and the mating connector transition from a non-connected state to a connected state. The inner shield (3 or 7) has a connection surface (310 or 710) at the second end (e4 or e8) that is electrically connected to the circuit board (150 or 550). The connection surface (310 or 710) is planar and continuous across the two tip regions (r1 or r7).

[0224] According to the above configuration, the inner shield (3 or 7) can be electrically connected to the ground wiring of the circuit board (150 or 550) over the entire length between the two tip regions (r1 or r7) of the connection surface (310 or 710). This makes it possible to suppress noise radiation.

[0225] The configurations other than those of the first aspect are not essential to the connector (sockets S1, S2 or headers H1, H2) and may be omitted as appropriate.

[0226] A connector device (100) according to a fourteenth aspect includes a connector (socket S1, S2 or header H1, H2) according to any one of the first to thirteenth aspects, and a mating connector.

[0227] According to the above configuration, it is possible to reduce the possibility that resonance of the transmission signal occurs in the electrical closed loop. [Explanation of symbols]
