[0026] (1) SUMMARY
[0027] The following describes the connector and the connector device of the embodiment using the drawings. However, the following embodiment is only one of various embodiments of the present disclosure. The following embodiment can be variously changed according to design, etc. as long as the object of the present disclosure is achieved. In addition, each drawing described in the following embodiment is a schematic view, and the size and the thickness of each structural element in the drawing do not necessarily reflect the actual size ratio.
[0028] As Figure 11 indicated, the connector device 100 has a first connector (the socket S1) and a second connector (the 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. When viewed from the socket S1, the header H1 is an "object side connector" connected to the socket S1. In contrast, when viewed from the header H1, the socket S1 is an "object side connector" connected to the header H1. That is, the connector device 100 has a connector (the socket S1 or the header H1) and an object side connector. In addition, when viewed from the socket S1, the terminal 8 of the header H1 is an "object side terminal" electrically connected to the terminal 4 of the socket S1. In contrast, when viewed from the header H1, the terminal 4 of the socket S1 is an "object side terminal" electrically connected to the terminal 8 of the header H1.
[0029] (1.1) Structure 1
[0030] As Figure 1 , Figure 5 , Figure 9 and Figure 13As shown, the connector (the socket S1 or the plug H1) of the present embodiment has the outside shield 1 (or 5), the terminal 4 (or 8), the housing 2 (or 6), and the inside shield 3 (or 7). The terminal 4 (or 8) is surrounded by the outside shield 1 (or 5). The terminal 4 (or 8) is electrically connected to an object-side terminal of an object-side connector. The outside shield 1 (or 5) is fixed with respect to the housing 2 (or 6). The housing 2 (or 6) holds the terminal 4 (or 8). The inside shield 3 (or 7) is surrounded by the outside shield 1 (or 5). The inside shield 3 (or 7) includes two tip end regions r1 (or r7). The two tip end regions r1 (or r7) include a tip end region r1 (or r7) that is opposite or directly bonded to the outside shield 1 (or 5) and a tip end region r1 (or r7) that is opposite or directly bonded to the outside shield 1 (or 5). In the plurality of electrical loops described below, the longest loop length of the electrical loop LO1, LO2, LO3 that does not surround other electrical loops is shorter than the wavelength of the maximum frequency of a transmission signal flowing to the terminal 4 (or 8). The two tip end regions r1 (or r7) are connected to the outside shield 1 (or 5) by two imaginary paths W7, W8 (or W9, W10) at the shortest distance L1 (or L7), respectively. The plurality of electrical loops pass through the outside shield 1 (or 5), the inside shield 3 (or 7), and the two imaginary paths W7, W8 (or W9, W10), and surround the terminal 4 (or 8), respectively. When viewed from the socket S1, the inside shield 7 of the plug H1 is an object-side inside shield. Conversely, when viewed from the plug H1, the inside shield 3 of the socket S1 is an object-side inside shield. When viewed from the socket S1, the outside shield 5 of the plug H1 is an object-side outside shield. Conversely, when viewed from the plug H1, the outside shield 1 of the socket S1 is an object-side outside shield.
[0031] According to the above-described structure, it is possible to reduce the possibility that resonance of a transmission signal occurs in an electrical loop.
[0032] In the present disclosure, the "maximum frequency of a transmission signal flowing to a terminal" means, in the case where a signal is transmitted via a terminal, for example, in the case where a radio frequency (RF) signal is transmitted, the maximum frequency of a carrier of the signal, and in the case where a digital signal is transmitted, the frequency of a 3 to 5 times higher harmonic of a clock frequency. The above-described maximum frequency is, for example, a value determined in accordance with the design of a connector by a manufacturer or the like that manufactures the connector or a value determined by the specifications of the connector or the like. The above-described maximum frequency is, for example, described in a design specification provided by the manufacturer as a value that can ensure the maximum frequency of operation.
[0033] (1.2) Structure 2
[0034] In addition, as Figure 1 , Figure 4 , Figure 5 , Figure 8 and the likeFigure 9 As shown in the drawings, the connector (the socket S1 or the plug H1) of the present embodiment has 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). The cylindrical portion 10 (or 50) is open at both ends 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 an object-side terminal of an object-side connector. The outer shield 1 (or 5) is fixed with respect to the housing 2 (or 6). The housing 2 (or 6) holds the terminal 4 (or 8). The outer shield 1 (or 5) has a top end face 102 (or 502), an outer peripheral face 101 (or 501) of the cylindrical portion 10 (or 50), and an inner peripheral face 103 (or 503) of the cylindrical portion 10 (or 50). The top end face 102 (or 502) is provided along an inner edge of the cylindrical portion 10 (or 50) at one of the both ends of the cylindrical portion 10 (or 50) to be described later. The one end refers to an end on the object-side connector side when a non-connected state of the connector and the object-side connector is changed to a connected state. At least one of the top end face 102 (or 502), the outer peripheral face 101 (or 501), and the inner peripheral face 103 (or 503) is seamless over the entire circumference D10 (or D50) of the cylindrical portion 10 (or 50).
[0035] In the present disclosure, "seamless" means that there is no joint and no crack.
[0036] According to the above-described structure, compared with a case where a joint or a crack is present in the top end face 102 (or 502), the outer peripheral face 101 (or 501), and the inner peripheral face 103 (or 503), respectively, it is possible to reduce noise radiated from the outer shield 1 (or 5).
[0037] In the connector as described in Japanese Patent Application Publication No. 2013-182808, although a shield cover is installed, noise is sometimes radiated.
[0038] In contrast, the connector of the present embodiment, as described above, is able to reduce noise radiated from the outer shield 1 (or 5).
[0039] (1.3) Structure 3
[0040] In addition, as Figure 1 , Figure 5 and Figure 10As illustrated, the connector (the socket S1 or the header H1) of the present embodiment has a plurality of terminals 4 (or 8). The plurality of terminals 4 (or 8) are electrically connected to a plurality of object-side terminals of an object-side connector, respectively. The connector also has a housing 2 (or 6) and an inner-side shield 3 (or 7). The housing 2 (or 6) holds the plurality of terminals 4 (or 8). The connector and the object-side connector are connected to each other by at least one of them moving toward the other in the up-down direction Dud. The plurality of terminals 4 (or 8) includes two terminals 4 (or 8). The two terminals 4 (or 8) are arranged on both sides across the inner-side shield 3 (or 7) in a front-rear direction Dfb orthogonal to the up-down direction Dud. The inner-side shield 3 (or 7) has a base portion 31 (or 71) and an extension portion 32 (or 72). The base portion 31 (or 71) extends along a left-right direction Dlr orthogonal to the up-down direction Dud and the front-rear direction Dfb. The extension portion 32 (or 72) protrudes from the base portion 31 (or 71) along the up-down direction Dud. The housing 2 (or 6) has a shield holding portion (a receiving portion 28 or 68). The shield holding portion holds the extension portion 32 (or 72).
[0041] According to the above-described structure, by the two terminals 4 (or 8) being arranged on both sides across the inner-side shield 3 (or 7), as compared with a case where there is no inner-side shield 3 (or 7), it is possible to reduce the possibility of transmission of noise occurring between the two terminals 4 (or 8). Also, since the extension portion 32 (or 72) of the connector is positioned by the shield holding portion (the receiving portion 28 or 68), it is possible to improve the accuracy of alignment between the extension portion 32 (or 72) of the connector and the object-side connector. Also, in the present embodiment, the extension portion 32 (or 72) of the connector is electrically connected to the inner-side shield of the object-side connector. According to the above-described structure, it is possible to improve the accuracy of electrical connection between the extension portion 32 (or 72) of the connector and the inner-side shield of the object-side connector.
[0042] In the connector as described in Japanese Patent Application Publication No. 2013-182808, there is a case where noise is transmitted between a plurality of contacts (terminals) and radiated noise is generated.
[0043] On the contrary, in the connector of the present embodiment, as described above, it is possible to reduce the possibility of transmission of noise occurring between the two terminals 4 (or 8).
[0044] (1.4) Structure 4
[0045] In addition, as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the connector (the socket S1 or the header H1) of the present embodiment has a plurality of terminals 4 (or 8), a housing 2 (or 6), and an inner side shield 3 (or 7). The plurality of terminals 4 (or 8) are electrically connected to a plurality of object side terminals of an object side connector, respectively. The housing 2 (or 6) holds the plurality of terminals 4 (or 8). The connector and the object side connector are connected to each other by at least one of them moving toward the other in the up-down direction Dud. In the embodiment, the socket S1 as the connector is configured to move relatively toward the header H1 as the object side connector in the upward direction Du as a predetermined direction and to be connected to the header H1. The plurality of terminals 4 (or 8) include two terminals 4 (or 8). The two terminals 4 (or 8) are disposed on both sides of the inner side shield 3 (or 7) in the front-rear direction Dfb orthogonal to the up-down direction Dud.
[0046] According to the above-described structure, compared to a case where the inner side shield 3 (or 7) is not provided, it is possible to reduce the possibility of transmission of noise occurring between the two terminals 4 (or 8).
[0047] In addition, in the above-described structure, the connector preferably further has an outer side shield 1 (or 5). The outer side shield 1 (or 5) surrounds the plurality of terminals 4 (or 8) and the inner side shield 3 (or 7).
[0048] By the connector having the outer side shield 1 (or 5), it is possible to reduce the possibility of transmission or radiation of noise occurring between the inside and the outside of the outer side shield 1 (or 5).
[0049] (2) Detailed Explanation
[0050] Hereinafter, the connector (the socket S1 and the header H1) of the present embodiment will be explained in detail with reference to Figures 1-14
[0051] Hereinafter, unless otherwise specified, the direction in which the socket S1 and the header H1 are connected to or separated from each other will be referred to as the up-down direction Dud, and the side of the header H1 will be referred to as the upward direction Du when viewed from the socket S1. In addition, the direction orthogonal to the up-down direction Dud and being the longitudinal direction of the housing 2 of the socket S1 will be referred to as the front-rear direction Dfb. In addition, the direction orthogonal to both the up-down direction Dud and the front-rear direction Dfb, that is, the short side direction of the housing 2 will be referred to as the left-right direction Dlr. That is, in Figure 1 In the drawings such as FIGS. 1 to 6, the upward direction Du, the downward direction Dd, the front direction Df, the rear direction Db, the left direction Dl, and the right direction Dr are defined as shown by arrows of “up”, “down”, “front”, “rear”, “left”, and “right”. However, these directions are not intended to define the use directions of the socket S1 and the header H1. In addition, the arrows indicating the directions in the drawings are merely for illustration and do not accompany physical entities.
[0052] As described above, the connector and the object side connector are connected to each other by at least one of moving toward the other in the up-down direction Dud. In the present embodiment, the socket S1 is disposed below the header H1, and the socket S1 and the header H1 can be connected to each other by performing at least one of an operation of moving the socket S1 in the upward direction Du and an operation of moving the header H1 in the downward direction Dd. Therefore, the "object side connector side when transitioning from the non-connection state to the connection state of the connector and the object side connector" means the upper side in the case where the socket S1 is the connector, and means the lower side in the case where the header H1 is the connector.
[0053] The socket S1 and the header H1 of the present embodiment are respectively mounted on a circuit substrate 150 or 550 (refer to Figure 10 ) such as a printed wiring board, a flexible printed wiring board, or the like. The socket S1 and the header H1 are used for electrically connecting between a plurality of circuit substrates mounted on a portable terminal such as a smartphone or the like. Of course, this is not intended to limit the use of the socket S1 and the header H1, and the socket S1 and the header H1 can be used for electronic devices other than portable terminals such as a camera module or the like. In addition, the use of the socket S1 and the header H1 is not limited to the use for electrically connecting between a plurality of circuit substrates, and for example, can be the use for electrically connecting between a circuit substrate and a display, between a circuit substrate and a battery, or the like.
[0054] The socket S1 and the header H1 can be provided in a state of not being connected to the circuit substrate 150 or 550, or can be provided in a state of being connected to the circuit substrate 150 or 550.
[0055] (2.1) Structure of Socket
[0056] First, the structure of the socket S1 of the present embodiment will be described.
[0057] The socket S1 is bilaterally symmetrical with an axis passing through the center of the socket S1 and along the up-down direction Dud as the axis of symmetry. As shown in Figure 1 , the socket S1 has an outer shield 1, a housing 2, a plurality of (two) inner shields 3, and a plurality of (eight) terminals 4. The outer shield 1 and each of the plurality of inner shields 3 are electrostatic shields. The outer shield 1 surrounds the plurality of terminals 4. That is, the outer shield 1 is disposed on the outer side of the plurality of terminals 4. The plurality of inner shields 3 are disposed on the inner side of the outer shield 1. In addition, the plurality of inner shields 3 are disposed on the inner side of the housing 2.
[0058] The circuit substrate 150 (refer to Figure 9) is mechanically and electrically connected to the socket S1. In the present embodiment, the circuit board 150 is a double-sided board, but the circuit board 150 can also be a multilayer board. The circuit board 150 has a base material 160 (refer to Figure 9 ) and conductors 170, 180 (refer to Figure 9 ). The base material 160 is, for example, a semiconductor base material or a glass base material. The conductor 170 is a pattern of a copper foil or the like provided on a surface of the base material 160. The conductor 170 is provided, for example, on substantially the entire surface of the side of the base material 160 on which the socket S1 is connected. The conductor 180 is, for example, solder. The conductor 180 is provided in predetermined regions (pads) of the conductor 170. The conductor 170 is electrically connected to the outside shield 1, the plurality of inside shields 3, and the plurality of terminals 4 via the conductor 180 (solder). The outside shield 1 and the plurality of inside shields 3 are electrically connected to, for example, a ground portion provided on the circuit board 150. In Figure 2 , the regions in which the conductor 180 (solder) is provided are indicated by two-dot chain lines.
[0059] (2.1.1) Housing of Socket
[0060] The housing 2 is a resin molded body. The housing 2 has electrical insulation. As shown in Figures 1-3 , 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-rear direction Dfb than in the left-right direction Dlr in plan view. The peripheral wall 22 protrudes upward from the entire periphery of one face (upper surface) of the thickness direction of the bottom wall 21. The housing 2 is a flat rectangular parallelepiped shape that extends orthogonally to the up-down direction Dud, and has a recessed portion 24 (refer to Figure 3 ) surrounded by the peripheral wall 22 in the central portion of the upper surface, which is one of the two faces in the up-down direction Dud and is the opposite face to the plug H1.
[0061] The peripheral wall 22 is in a cylindrical shape. The peripheral wall 22 surrounds the plurality of terminals 4. The peripheral wall 22 is continuous on the entire periphery of the circumferential direction D22 (refer to Figure 1 ) of the peripheral wall 22. In other words, the peripheral wall 22 is formed so as to have no cracks on the entire periphery of the circumferential direction D22 of the peripheral wall 22. As shown in Figure 1 , the peripheral wall 22 includes two peripheral walls 221 and two peripheral walls 222. The two peripheral walls 221 are portions of the peripheral wall 22 that respectively extend substantially in parallel with the front-rear direction Dfb and are opposite to each other in the left-right direction Dlr with the recessed portion 24 interposed therebetween. The two peripheral walls 222 are portions of the peripheral wall 22 that respectively extend substantially in parallel with the left-right direction Dlr and are opposite to each other in the front-rear direction Dfb with the recessed portion 24 interposed therebetween. The two peripheral walls 222 respectively join the end portions of the two peripheral walls 221 to each other. That is, the housing 2 has a shape in which one opening face (lower surface) of the peripheral wall 22, which is a square cylindrical shape in cross section, is closed by the bottom wall 21.
[0062] As shown in Figure 3As shown, the housing 2 also has a wall portion 25, a wall portion 26, and a wall portion 27. The wall portion 25, the wall portion 26, and the wall portion 27 protrude upward from the bottom wall 21 in the upward direction Du. The wall portion 25, the wall portion 26, and the wall portion 27 are disposed in the recessed portion 24. That is, the wall portion 25, the wall portion 26, and the wall portion 27 are surrounded by the peripheral wall 22. The wall portion 25, the wall portion 26, and the wall portion 27 each have a shape of a rectangular parallelepiped. When viewed in the upward-downward direction Dud, the wall portion 25, the wall portion 26, and the wall portion 27 each are longer in the front-rear direction Dfb than in the left-right direction Dlr. That is, the wall portion 25, the wall portion 26, and the wall portion 27 each are a wall portion having a thickness in a direction along the left-right direction Dlr. The wall portion 25, the wall portion 26, and the wall portion 27 are arranged in order from left to right, that is, in the rightward direction Dr.
[0063] Each of the plurality of wall portions (the wall portion 25, the wall portion 26, and the wall portion 27) has a plurality of (two) receiving portions 28. The plurality of receiving portions 28 each receive the extension portion 32 of the inner shield 3. The plurality of receiving portions 28 are each a through-hole provided in the wall portion. The receiving portion 28 penetrates the wall portion in the upward-downward direction Dud. The receiving portion 28 also penetrates the bottom wall 21 in the upward-downward direction Dud. In addition, when viewed in the upward-downward direction Dud, the receiving portion 28 provided in the wall portion 25 and the wall portion 27 is a recessed portion from a side surface (a surface intersecting the left-right direction Dlr) of the wall portion 25 (the wall portion 27).
[0064] In addition, each of the plurality of wall portions (the wall portion 25, the wall portion 26, and the wall portion 27) has a plurality of terminal holding portions 29. The plurality of terminal holding portions 29 each hold the terminal 4. The plurality of terminal holding portions 29 are each a through-hole provided in the wall portion. The through-hole penetrates in the upward-downward direction Dud in the terminal holding portion 29. In addition, when viewed in the upward-downward direction Dud, the terminal holding portion 29 is a recessed portion from a side surface (a surface intersecting the left-right direction Dlr) of the wall portion. The plurality of terminal holding portions 29 correspond in two groups of two. The two terminal holding portions 29 corresponding to each other are arranged in the left-right direction Dlr. Furthermore, a portion between the two terminal holding portions 29 corresponding to each other in the bottom wall 21 is a through-hole 211 into which the terminal 4 is inserted.
[0065] Multiple terminals 4 are fixed to the housing 2 by pressing. That is, multiple terminals 4 are held by the housing 2 by being pressed into the housing 2 in one direction (upward). In this embodiment, eight terminals 4 are fixed to the housing 2. The eight terminals 4 are arranged in two rows. That is, four of the eight terminals 4 constitute the first row, and the remaining four terminals 4 constitute the second row. The four terminals 4 in each row are arranged in the front-rear direction Dfb. The four terminals 4 constituting the first row are held by the terminal holding portion 29 of the wall portion 25 and the terminal holding portion 29 of the wall portion 26, respectively. The four terminals 4 constituting the second row are held by the terminal holding portion 29 of the wall portion 26 and the terminal holding portion 29 of the wall portion 27, respectively. That is, each terminal 4 is disposed between the two wall portions and supported by the two wall portions from both sides.
[0066] like Figure 2 As shown, the bottom wall 21 has multiple notches 212. These notches 212 are positioned opposite the substrate connection portion 45 of the terminal 4 (described later) when viewed along the vertical direction Dud. Additionally, the bottom wall 21 has multiple (two) receiving slots 213. Each receiving slot 213 is a groove provided on the lower surface of the bottom wall 21. The receiving slot 213 is longer in the horizontal direction Dlr than in the front-back direction Dfb. The receiving slot 213 receives the base 31 of the inner shielding member 3.
[0067] The peripheral wall 22 has a plurality of (4) insertion portions 223. The plurality of (4) insertion portions 223 are recesses that are recessed from the side surfaces (inner surfaces) of the two peripheral walls 221 and the two peripheral walls 222 respectively. As will be described later, shielding protrusions 14, which are part of the outer shielding member 1, are inserted into the plurality of (4) insertion portions 223 respectively.
[0068] (2.1.2) External shielding of the socket
[0069] The outer shield 1 surrounds multiple terminals 4 and multiple inner shields 3. The outer shield 1 comprises a material such as metal as the main material or a plating layer forming the surface. Here, as an example, the outer shield 1 is formed primarily of metal. Figure 1 , Figure 4 As shown, the outer shield 1 has a cylindrical portion 10 and a plurality of (4) shield protrusions 14. The cylindrical portion 10 includes an outer peripheral wall 11, a top wall 12, and an inner peripheral wall 13.
[0070] The outer peripheral wall 11 has a square tube shape with a square cross section. The outer peripheral wall 11 includes two outer peripheral walls 111 and two outer peripheral walls 112. The two outer peripheral walls 111 are portions of the outer peripheral wall 11 that respectively extend substantially in parallel with the front-rear direction Dfb and are opposite to each other in the left-right direction Dlr. The two outer peripheral walls 112 are portions of the outer peripheral wall 11 that respectively extend substantially in parallel with the left-right direction Dlr and are opposite to each other in the front-rear direction Dfb. The two outer peripheral walls 112 respectively join end portions of the two outer peripheral walls 111 to each other. Lower end portions (lower surfaces) of the outer peripheral walls 111 and the outer peripheral walls 112 are parallel to planes that extend in the front-rear direction Dfb and the left-right direction Dlr and are formed in substantially the same plane.
[0071] The top wall 12 has a rectangular frame shape when viewed in the up-down direction Dud. The top wall 12 is continuous with the upper end of the outer peripheral wall 11 and extends toward the inner side of the outer peripheral wall 11 when viewed in the up-down direction Dud.
[0072] The inner peripheral wall 13 is provided on the inner side of the outer peripheral wall 11. The inner peripheral wall 13 has a square tube 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 joined by the top wall 12.
[0073] The inner peripheral wall 13 includes two inner peripheral walls 131 and two inner peripheral walls 132. The two inner peripheral walls 131 are portions of the inner peripheral wall 13 that respectively extend substantially in parallel with the front-rear direction Dfb and are opposite to each other in the left-right direction Dlr. The two inner peripheral walls 132 are portions of the inner peripheral wall 13 that respectively extend substantially in parallel with the left-right direction Dlr and are opposite to each other in the front-rear direction Dfb. The two inner peripheral walls 132 respectively join end portions of the two inner peripheral walls 131 to each other.
[0074] The outer peripheral wall 11, the top wall 12, and the inner peripheral wall 13 constitute a cylindrical portion 10 that is open at both ends in the up-down direction Dud. 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. In addition, the outer shield 1 has a top end surface 102. The top end surface 102 is provided at one end (the upper end) of the cylindrical portion 10 on the side of the object-side connector (in this case, the plug H1) when transitioning from a non-connected state to a connected state of the connector (in this case, the socket S1) and the object-side connector (in this case, the plug H1). The top end surface 102 is annular along the inner edge of the cylindrical portion 10. Here, the upper surface of the top wall 12 corresponds to the top end surface 102. In addition, the inner edge of the top end surface 102 corresponds to the inner edge of the cylindrical portion 10 at the upper end of the cylindrical portion 10.
[0075] The boundary portion b1 between the top end surface 102 and the outer peripheral surface 101 is a curved surface (see FIG. 2) in a circular arc shape when viewed in the front-rear direction Dfb. Figure 9). In addition, the boundary portion b2 between the tip end face 102 and the inner peripheral face 103 is a curved face (see Figure 9 ). Further, in this embodiment, the tip end face 102 is defined as a region in the outer face of the cylindrical portion 10, which makes an acute angle of 0 degrees or more and less than 45 degrees with respect to the up-down direction Dud. In addition, a face outside the above-mentioned acute angle of 45 degrees or more is defined as the outer peripheral face 101, and a face inside the above-mentioned acute angle of 45 degrees or more is defined as the inner peripheral face 103. The cylindrical portion 10 surrounds the hollow portion 10S. The boundary portion bl is provided so as to include a partial region of the tip end face 102 and a partial region of the outer peripheral face 101 on the entire circumference of the circumferential direction D10 (see Figure 4 ) of the cylindrical portion 10, which surrounds the hollow portion 10S. The boundary portion b2 is provided so as to include a partial region of the tip end face 102 and a partial region of the inner peripheral face 103 on the entire circumference of the circumferential direction D10 of the cylindrical portion 10.
[0076] The plurality of (four) shield protrusions 14 are each provided in correspondence with each of the two inner peripheral walls 131 and the two inner peripheral walls 132. Each shield protrusion 14 protrudes downward from the corresponding inner peripheral wall 131 or 132. The plurality of (four) shield protrusions 14 correspond one-to-one with the plurality of (four) insertion portions 223 (see Figure 2 ) provided in the housing 2. Each shield protrusion 14 is inserted into the corresponding insertion portion 223.
[0077] The outer shield 1 is insert-molded in the housing 2. More specifically, the outer shield 1 is insert-molded in the housing 2 in such a manner that the circumferential wall 22 of the housing 2 enters between the outer peripheral wall 11 and the inner peripheral wall 13 of the outer shield 1.
[0078] The entire faces of the outer shield 1 are formed without seams. The outer shield 1 is formed, for example, by drawing processing, whereby the entire faces of the outer shield 1 are formed without seams. In this embodiment, at least the outer peripheral face 101 and the inner peripheral face 103 among the faces of the outer shield 1 are seamless (i.e., free from seams and cracks) on the entire circumferential direction D10 of the cylindrical portion 10. Also in this embodiment, the tip end face 102 is seamless on the entire circumferential direction D10 of the cylindrical portion 10.
[0079] For example, when the outer peripheral face 101 is focused on, as shown in Figure 4 , the outer peripheral face 101 includes the outer face 1110 of each of the two outer peripheral walls 111 and the outer face 1120 of each of the two outer peripheral walls 112. The outer faces 1110 and 1120 are each seamless. Also, the two faces, i.e., the outer faces 1110 and 1120, whose normal directions are different from each other, are seamlessly connected. In this way, the outer peripheral face 101 is seamless on the entire circumferential direction D10 of the cylindrical portion 10.
[0080] In addition, when the inner peripheral face 103 is focused on, as shown inFigure 4 As shown, the inner circumferential surface 103 includes the outer surfaces 1310 of each of the two inner circumferential walls 131 and the outer surfaces 1320 of each of the two inner circumferential walls 132. The outer surfaces 1310 and 1320 are seamless. Furthermore, the two surfaces with different normal directions, namely the outer surfaces 1310 and 1320, are seamlessly connected. Thus, the inner circumferential surface 103 is seamless over the entire circumferential direction D10 of the cylindrical portion 10.
[0081] In addition, at least one of the boundary portion b1 between the top surface 102 and the outer peripheral surface 101 and the boundary portion b2 between the top surface 102 and the inner peripheral surface 103 (both in this embodiment) is seamless over the entire circumference of the cylindrical portion 10 in the circumferential direction D10.
[0082] For example, in Figure 4 At the upper right position of the paper (the corner of the outer shield 1), the outer surface 1110 of the outer peripheral wall 111, the outer surface 1120 of the outer peripheral wall 112, and the top surface 102 are seamlessly connected. That is, the three surfaces with different normal directions—outer surface 1110, outer surface 1120, and top surface 102—are seamlessly connected. Furthermore, in Figure 4 On the right side of the paper, the two surfaces with different normal directions, namely the outer surface 1110 and the top surface 102, are seamlessly connected. Furthermore, in Figure 4 Above the paper surface, the two surfaces with different normal directions, namely the outer surface 1120 and the top surface 102, are seamlessly connected. Thus, the boundary portion b1 is seamless over the entire circumference D10 of the cylindrical portion 10.
[0083] Additionally, for example, in Figure 4 At the lower left corner of the paper (corner of the outer shield 1), the outer surface 1310 of the inner peripheral wall 131, the outer surface 1320 of the inner peripheral wall 132, and the top surface 102 are seamlessly connected. That is, the three surfaces with different normal directions—outer surface 1310, outer surface 1320, and top surface 102—are seamlessly connected. Furthermore, in Figure 4 On the left side of the paper, the two surfaces with different normal directions, namely the outer surface 1310 and the top surface 102, are seamlessly connected. Furthermore, in Figure 1 Below the paper, the two surfaces with different normal directions, namely the outer surface 1320 and the top surface 102, are seamlessly connected. Thus, the boundary portion b2 is seamless over the entire circumference D10 of the cylindrical portion 10.
[0084] (2.1.3) Inner shielding of the socket
[0085] In this embodiment, the two inner shielding members 3 have the same shape. The inner shielding member 3 comprises metal as the main material or a material constituting a surface plating, etc. Here, as an example, the inner shielding member 3 is formed primarily of metal.Figure 9 , Figure 9 As shown, the inner shield 3 has a base 31 and a plurality of (3) extensions 32 (two extensions 33 and one extension 34).
[0086] The base 31 has a length along the left-right direction Dlr. The base 31 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of the base 31, the base 31 is longer in the left-right direction Dlr than in the up-down direction Dud. The base 31 is housed in a receiving groove 213 provided on the bottom wall 21 of the housing 2.
[0087] like Figure 10 As shown, multiple extensions 32 protrude upwards from the base 31. That is, the multiple extensions 32 protrude along the vertical direction Dud, facing the direction that becomes the target connector side when transitioning from a non-connected state to a connected state between the connector (here, socket S1) and the target connector (here, plug H1). Each extension 32 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of each extension 32, each extension 32 is longer in the vertical direction Dud than in the horizontal direction Dlr. Alternatively, the thickness direction of each extension 32 could also be the horizontal direction Dlr.
[0088] The extension portion 33 includes an extension body 331 and an abutment portion 332. The extension body 331 is a portion that protrudes from the base 31. The abutment portion 332 is a portion that contacts the inner shield (inner shield 7) on the object side of the object-side connector (plug H1). The abutment portion 332 protrudes from the extension body 331 in the length direction (direction D1 or direction Dr). The abutment portion 332 is provided on the surface 332S (here, the left or right side) of the extension portion 33 in the length direction of the extension portion 33 (extension body 331). That is, the abutment portion 332 protrudes from the extension body 331 in the left-right direction D1r.
[0089] The abutting portions 332 of the two extensions 33 are opposite each other in the left-right direction (Dlr). When the socket S1 is connected to the plug H1, each abutting portion 332 is configured to contact the abutting portion 720 of the inner shield 7 of the plug H1 (see reference). Figure 3 Therefore, the two inner shields 3 are electrically connected to the corresponding inner shields 7 of the two inner shields 7 of the plug H1. Specifically, the two extensions 72 of the inner shield 7 are inserted between the two extensions 33 of the inner shield 3. At this time, under the elastic action of the two extensions 72 and the two extensions 33, the two extensions 72 are pressed by the two extensions 33.
[0090] The extension portion 34 includes an extension portion main body 341 and a plurality of (two) holding protrusions 342. The extension portion main body 341 is a portion protruding 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 at the left end and the right end of the extension portion main body 341. That is, one of the two holding protrusions 342 protrudes from the extension portion main body 341 in the left direction Dl, and the other protrudes from the extension portion main body 341 in the right direction Dr.
[0091] The receptacle S1 has three extension portions 32 in each of the two inner side shields 3. That is, the receptacle S1 has a total of six extension portions 32. The six housing portions 28 (refer to Figure 9 ) provided in the housing 2 correspond to the six extension portions 32 one-to-one. Each of the extension portions 32 is housed in the corresponding housing portion 28. More specifically, the extension portions 33 are housed in the housing portions 28 provided in the wall portions 25 and 27, respectively, and the extension portion 34 is housed in the housing portion 28 provided in the wall portion 26. In the extension portion 34, the width of the left and right directions Dlr of the two holding protrusions 342 is slightly larger than the width of the left and right directions Dlr of the housing portion 28. The inner side shield 3 is fixed to the housing 2 by press-fitting. That is, the inner side shield 3 is held by the housing 2 by being press-fitted in one direction (upward). The inner side shield 3 is held by the housing 2 in a state in which the two holding protrusions 342 are sandwiched by the inner surfaces of the housing portions 28.
[0092] Here, the housing spaces of the two extension portions 33 in the shield holding portions (housing portions 28) are each larger than the two extension portions 33. That is, there is play in the alignment between the two extension portions 33 and the inner surfaces of the housing portions 28, respectively. The function of holding the inner side shield 3 to the housing 2 is achieved by at least the extension portion 34. That is, the inner side shield 3 is held by the housing 2 by at least the extension portion 34 being press-fitted into the housing portion 28. In summary, the plurality of extension portions 32 include the extension portion 33 including the abutting portion 332 that comes into contact with the inner side shield 7 of the object side connector (here, the plug H1), and the extension portion 34 that is held by the shield holding portion (housing portion 28). However, the extension portion 34 can also include an abutting portion that comes into contact with the inner side shield 7 of the object side connector (here, the plug H1).
[0093] As shown in Figure 9 , the base portion 31 of the inner side shield 3 is located at the lower end of the receptacle S1. The inner side shield 3 is surrounded by the outer side shield 1. The inner side shield 3 includes two top end regions r1 opposite the outer side shield 1. The two top end regions r1 are provided at both ends (the left end and the right end) in the length direction of the base portion 31.
[0094] Here, the outer shield 1 has an end el and an end e2. The end el is an end (upper end) on the side of the object-side connector (here, the plug H1) when transitioning from the non-connected state to the connected state of the connector (here, the socket S1) and the object-side connector. The end e2 is an end (lower end) on the side opposite the end el. Further, here, the end e2 is provided as a region along the entire circumference of the circumferential direction D10 of the cylindrical portion 10. The outer shield 1 opposes the two tip end regions r1 in the region including the end e2.
[0095] The outer shield 1 opposes at least one of the two tip end regions r1 with the gap g1 in the region including the end e2. As shown in Figure 2 The conductors 170, 180 of the circuit board 150 are electrically connected to the outer shield 1. In addition, the conductors 170, 180 are provided so as to span the end e2 of the outer shield 1 and the two tip end regions r1 of the inner shield 3, respectively. That is, the outer shield 1 is electrically connected to the inner shield 3 by the conductors 170, 180. On the other hand, in the 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 end regions r1 (both in the present embodiment) with the gap g1. The shortest distance L1 between the outer shield 1 and at least one of the two tip end regions r1 in the gap g1 is 0.01 mm or more and 0.1 mm or less.
[0096] The inner shield 3 has an end e3 and an end e4. The end e3 is an end (upper end) on the side of the object-side connector (here, the plug H1) when transitioning from the non-connected state to the connected state of the connector (here, the socket S1) and the object-side connector. The end e4 is an end (lower end) on the side opposite the end e3. The inner shield 3 has a connection surface 310 (lower surface) electrically connected to the circuit board 150 at the end e4. The connection surface 310 is planar and continuous across between the two tip end regions r1. In more detail, the connection surface 310 is a rectangular planar surface connecting between the two tip end regions r1.
[0097] (2.1.4) Terminals of the socket
[0098] (2.1.4.1) Configuration
[0099] As shown in Figure 3 , Figure 2 The plurality of (8) terminals 4 include a plurality of (6) low-frequency terminals 4P and a plurality of (two) high-frequency terminals 4T. Each terminal 4 is inserted into the through-hole 211 of the bottom wall 21 of the housing 2 and is held by the terminal holding portion 29.
[0100] The two high-frequency terminals 4T are arranged on both sides with at least one inner shield 3 interposed therebetween. In other words, at least one inner shield 3 is interposed between the two high-frequency terminals 4T. Thereby, it is possible to reduce the possibility of transmission of noise occurring between the two high-frequency terminals 4T.
[0101] More specifically, the two high-frequency terminals 4T are arranged on both sides in the front-rear direction Dfb, i.e., the front side and the rear side of the inner shield 3, with respect to at least one inner shield 3. In Figure 11 In the present embodiment, when one of the two inner shields 3 is taken into account, one high-frequency terminal 4T is arranged in front of the inner shield 3, i.e., in the front direction Df from the inner shield 3, and the remaining one high-frequency terminal 4T is arranged in the rear direction Db from the inner shield 3. In addition, the two inner shields 3 are arranged between the two high-frequency terminals 4T. In addition, the length direction (left-right direction Dlr) of the inner shield 3 is a direction that intersects the direction (substantially the front-rear direction Dfb) in which the two high-frequency terminals 4T are arranged.
[0102] The six low-frequency terminals 4P are arranged between the 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. Also, 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 Dfb.
[0103] The three low-frequency terminals 4P of each row are arranged at equal intervals in the front-rear direction Dfb. In addition, a high-frequency terminal 4T is arranged in front of or behind the low-frequency terminal 4P at the end of each row, i.e., a high-frequency terminal 4T is arranged in the front direction Df or the rear direction Db from the low-frequency terminal 4P at the end of each row. The interval between the low-frequency terminals 4P and the high-frequency terminal 4T is an integer multiple (2 times in the present embodiment) of the interval of the three low-frequency terminals 4P. With such an arrangement, it is possible to easily implement the process of assembling the six low-frequency terminals 4P and the two high-frequency terminals 4T together into the housing 2.
[0104] In the present embodiment, the interval between the low-frequency terminals 4P and the high-frequency terminal 4T is longer than the interval of the three low-frequency terminals 4P. Thereby, it is possible to secure a space in which the inner shield 3 is arranged between the low-frequency terminals 4P and the high-frequency terminal 4T.
[0105] Since a space for arranging a plurality of low-frequency terminals 4P is provided between the two high-frequency terminals 4T, the distance between the two high-frequency terminals 4T can be ensured. Thus, the possibility of transmission of noise occurring between the two high-frequency terminals 4T can be further reduced. In addition, the two high-frequency terminals 4T are arranged at diagonally opposite positions on the inner side of the peripheral wall 22 of the housing 2. Thus, the distance between the two high-frequency terminals 4T can be further lengthened.
[0106] The two high-frequency terminals 4T are electrically connected to signal lines patterned by the conductor 170 on the circuit substrate 150. At least one of the six low-frequency terminals 4P is electrically connected to a power supply line patterned by the conductor 170 on the circuit substrate 150. The two high-frequency terminals 4T transmit signals of higher frequency than the six low-frequency terminals 4P. The frequency of the signals transmitted by the two high-frequency terminals 4T is, for example, about 5 GHz to 50 GHz.
[0107] In addition, at least one of the six low-frequency terminals 4P can also be electrically connected to the inner shield 3. Thus, at least one of the six low-frequency terminals 4P is at 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 ground potentials. At least one of the six low-frequency terminals 4P can be electrically connected to the inner shield 3, for example, via the conductors 170, 180 of the circuit substrate 150. In addition, at least one of the six low-frequency terminals 4P can also be electrically connected to the inner shield 3 without the aid of the circuit substrate 150.
[0108] (2.1.4.2) Shape
[0109] The shape of each terminal 4 is the same as that of the other terminals 4. Each terminal 4 is formed, for example, by blanking and bending processing of a metal plate, and the like. As shown in FIG. 2, each terminal 4 has a contact portion 41, a base portion 42, a connecting portion 43, a protruding portion 44, a substrate connecting portion 45, and a contact portion 46. Figure 2
[0110] The substrate connecting portion 45 is electrically connected to the conductor 180 (solder) of the circuit substrate 150, for example. That is, the substrate connecting portion 45 is joined to the circuit substrate 150 by a joining means such as soldering. Thus, the circuit substrate 150 and the terminal 4 are mechanically and electrically connected. In addition, as shown in FIG. 2, the substrate connecting portion 45 is surrounded by the outer shield 1 when viewed in the up-down direction Dud. Also, at least a part of the substrate connecting portion 45 and at least a part of the outer shield 1 exist on one plane orthogonal to the up-down direction Dud. Figure 12
[0111] The connecting portion 43 is formed in the shape of a letter U open to the downward direction Dd. The connecting portion 43 connects the upper end portion of the base portion 42 and the upper end portion of the contact portion 41. The lower end portion of the base portion 42 is connected to the substrate connecting portion 45.
[0112] The protruding portion 44 is formed in a letter U shape that is open in the upward direction Du. The protruding portion 44 links the lower end portion of the contact portion 41 and the contact portion 46. The contact portion 41 and the contact portion 46 face each other in the left-right direction Dlr. In the present embodiment, at least the linking portion 43 and the protruding portion 44 in the terminal 4 have elasticity.
[0113] In a state where the terminal 4 is held by the housing 2, at least a part of the contact portion 41 and the contact portion 46 is exposed when viewed from the upward direction. The contact portion 41 and the contact portion 46 come into contact with the corresponding terminal 8 among the plurality of terminals 8 (object side terminals) of the plug H1 (object side connector) and are electrically connected to the terminal 8 (refer to Figure 3 ). 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 contact portion 41 and the contact portion 46 are pressed by the terminal 8 under the elasticity of the protruding portion 44.
[0114] The terminal 4 also has a force sensation portion 47. The force sensation portion 47 generates a click feeling when the terminal 4 comes into contact with the terminal 8 (object side terminal). The force sensation portion 47 is a protrusion that protrudes from the contact portion 41. When the force sensation portion 85 (protrusion) that the terminal 8 has passes over the force sensation portion 47, the click feeling is generated. Specifically, by the force sensation portion 85 moving downward and passing over the force sensation portion 47, the amount of force acting between the terminal 4 and the terminal 8 decreases, and thus an operator who connects the terminal 4 and the terminal 8 can feel the decrease in the amount of force as the click feeling. The operator can understand the progress of the connection between the socket S1 and the plug H1 by feeling the click feeling. Furthermore, the connection between the socket S1 and the plug H1 and the connection between the terminal 4 and the terminal 8 accompanying this are not limited to being performed by a person's hand, but can be performed by a machine.
[0115] When the terminal 4 and the terminal 8 are connected, the contact portion 46 is inserted into the recess 840 of the terminal 8. When transitioning from a state where the terminal 4 and the terminal 8 are connected to a non-connected state, a certain amount of force is required for the force sensation portion 85 to be able to move upward and pass over the force sensation portion 47 and for the contact portion 46 to be able to escape from the recess 840. In this way, the set of the force sensation portion 85 and the force sensation portion 47 and the set of the contact portion 46 and the recess 840 respectively constitute a locking mechanism that can maintain the connected state between the socket S1 and the plug H1.
[0116] As shown in Figure 2 , the abutting portion 332 of the inner shield 3 and the contact portion 41 of at least one of the plurality of terminals 4 are arranged in the front-back direction Dfb.
[0117] (2.1.5) Socket Side Circuit Board
[0118] The socket S1 is electrically connected to the conductor 180 (solder) of the circuit board 150. InFigure 13 The diagram shows the area on the lower surface of the socket S1 where the conductor 180 is located, indicated by a dashed line. The conductor 180 is partially located on the lower surface of the outer shield 1 along the circumferential direction D10 of the outer shield 1. Here, conductors 180 are provided in multiple regions on the lower surface of the outer shield 1, spaced apart on the circumferential direction D10. However, it is also possible that conductors 180 are continuously provided on the lower surface of the outer shield 1, covering the entire circumference D10 of the outer shield 1. That is, it is also possible that the outer shield 1 is in continuous contact with the conductor 180 along the entire circumferential direction D10.
[0119] Furthermore, a portion of the conductor 180 is configured to have an outer shield 1 and each inner shield 3 mounted on it. Also, a portion of the conductor 180 is provided on the lower surface of each inner shield 3 along the length of the inner shield 3. Here, on the lower surface of each inner shield 3, multiple (3) regions are provided with conductors 180 spaced apart along the length of the inner shield 3. However, it is also possible that the conductors 180 are continuously provided on the lower surface of each inner shield 3 along the entire length of the inner shield 3. That is, it is also possible that the inner shield 3 is in continuous contact with the conductor 180 along its entire length.
[0120] A portion of conductor 180 is electrically connected to the outer shield 1 and each of the inner shields 3, and is also electrically connected to the conductor 170 of the circuit board 150, which has a ground potential. That is, the potentials of the outer shield 1 and each of the inner shields 3 are ground potentials. A large portion of the surface of the substrate 160 on the side connected to the socket S1 is preferably occupied by the conductor 170 with a ground potential. In other words, a so-called ground layer is preferably provided on the circuit board 150. This improves the shielding effect.
[0121] Additionally, a portion of conductor 180 is electrically connected to the substrate connection portion 45 of terminal 4. Terminal 4 is electrically connected to appropriate circuits via conductor 170 (wiring pattern) of circuit board 150. For example, a plurality of high-frequency terminals 4T are electrically connected to circuitry for processing signals. Additionally, for example, at least a portion of a plurality of low-frequency terminals 4P are electrically connected to wiring for transmitting signals at frequencies lower than those transmitted by high-frequency terminals 4T, or to power supply circuitry or grounding.
[0122] (2.1.6) Electrical closed loop of the socket
[0123] Figure 13 The configuration of the outer shield 1, multiple (two) inner shields 3 and multiple (eight) terminals 4 as viewed from below is schematically shown.
[0124] The socket S1 is formed with at least three electric loops LO1, LO2, LO3 described below. Each electric loop LO1, LO2, LO3 includes the outer shield 1, two inner shields 3, and at least the outer shield 1 and one or two inner shields 3 of the imaginary paths W7, W8, W9, W10. That is, each electric loop LO1, LO2, LO3 includes a path that ends in the outer shield 1 and a path that ends in one inner shield 3 or each inner shield 3 of the two inner shields 3, and optionally includes at least one of the imaginary paths W7, W8, W9, W10. The two imaginary paths W7, W8 (or W9, W10) respectively connect the two tip regions r1 of the outer shield 1 and the inner shield 3 with the shortest distance L1. Each electric loop LO1, LO2, LO3 encloses at least one terminal 4. Each electric loop LO1, LO2, LO3 does not enclose other electric loops. Other electric loops include the outer shield 1, two inner shields 3, and at least the outer shield 1 and one or two inner shields 3 of the imaginary paths W7, W8, W9, W10. The electric loop LO1 does not enclose the electric loops LO2, LO3, the electric loop LO2 does not enclose the electric loops LO1, LO3, and the electric loop LO3 does not enclose the electric loops LO1, LO2.
[0125] In the present disclosure, when it is said that a certain electric loop (hereinafter referred to as a first loop) encloses another electric loop (hereinafter referred to as a second loop), a part of the first loop and a part of the second loop can also overlap.
[0126] The longest loop length among the electric loops LO1, LO2, LO3 is shorter than the wavelength of the maximum frequency of the transmission signal flowing to the terminal 4. Thus, it is possible to reduce the possibility of resonance of the transmission signal. Here, more specifically, the above-mentioned maximum frequency is the maximum frequency of the transmission signal flowing to the high-frequency terminal 4T. That is, in the present embodiment, the above-mentioned maximum frequency is determined in accordance with the specifications of the high-frequency terminal 4T.
[0127] The path W2, W3, W4 of the outer shield 1, the inner shield 3, and the paths W7, W8 constitute an electrical closed loop LO5. The path W2, W1, W4 of the outer shield 1, the inner shield 3, and the paths W9, W10 constitute an electrical closed loop LO6. In this way, two of the imaginary paths W7 to W10, the outer shield 1, and the inner shield 3 constitute a plurality of electrical closed loops LO1, LO2, LO3, LO5, LO6 that each pass through all of the two of the imaginary paths W7 to W10, the outer shield 1, and the inner shield 3, including the outer shield 1 and the inner shield 3, and enclose the terminal 4. The electrical closed loop LO5 of the plurality of electrical closed loops LO1, LO2, LO3, LO5, LO6 encloses the electrical closed loops LO2, LO3 other than itself, and the electrical closed loop LO6 encloses the electrical closed loops LO1, LO2 other than itself. None of the one or more specific electrical closed loops LO1, LO2, LO3 of the plurality of electrical closed loops LO1, LO2, LO3, LO5, LO6 encloses any electrical closed loop other than itself of the plurality of electrical closed loops LO1, LO2, LO3, LO5, LO6. The longest of the lengths of the loops of the one or more specific electrical closed loops LO1, LO2, LO3 is shorter than the wavelength of the maximum frequency of the transmission signal flowing to the terminal 4.
[0128] Further, in the case where the connector has only one inner shield, two imaginary paths are constituted in total at both ends thereof, and the two imaginary paths, the outer shield, and the inner shield constitute a plurality of electrical closed loops.
[0129] In the connector as described in Japanese Patent Application Publication No. 2013-182808, the transmission signal transmitted by the connector sometimes resonates.
[0130] In contrast, in the connector of the present embodiment, it is possible to reduce the possibility that the transmission signal flowing to the terminal 4 resonates.
[0131] Further, if not limited to within a plane orthogonal to the up-down direction Dud, electrical closed loops other than the electrical closed loops LO1, LO2, LO3 are also formed in the receptacle S1, but they are all shorter in length of the loop than the electrical closed loops LO1, LO2, LO3, and thus are not employed here.
[0132] Next, the paths W1 to W10 that constitute the electrical closed loops LO1, LO2, LO3 are described.
[0133] Two inner side shields 3 are arranged in a manner aligned before and after the socket S1. On the left side surface of the outer side shield 1, there is an area r2 opposite the top end area r1 of the left side of the front inner side shield 3 and an area r3 opposite the top end area r1 of the left side of the rear inner side shield 3. On the right side surface of the outer side shield 1, there is an area r4 opposite the top end area r1 of the right side of the front inner side shield 3 and an area r5 opposite the top end area r1 of the right side of the rear inner side shield 3.
[0134] The path W1 is included in the front area of the outer side shield 1 and connects the areas r4, r2 along the outer side shield 1. The path W2 connects the areas r2, r3 along the left side surface of the outer side shield 1.
[0135] The path W3 is included in the rear area of the outer side shield 1 and connects the areas r3, r5 along the outer side shield 1. The path W4 connects the areas r5, r4 along the right side surface of the outer side shield 1.
[0136] The path W5 connects the two top end areas r1 of the upper inner side shield 3. The path W6 connects the two top end areas r1 of the lower inner side shield 3.
[0137] The path W7 connects the area r2 of the outer side shield 1 and the top end area r1 of the left side of the front inner side shield 3 at the shortest distance L1. The path W8 connects the area r4 of the outer side shield 1 and the top end area r1 of the right side of the front inner side shield 3 at the shortest distance L1.
[0138] The path W9 connects the area r3 of the outer side shield 1 and the top end area r1 of the left side of the rear inner side shield 3 at the shortest distance L1. The path W10 connects the area r5 of the outer side shield 1 and the top end area r1 of the right side of the rear inner side shield 3 at the shortest distance L1.
[0139] The electrical closed loop LO1 is formed by the paths W1, W7, W5, W8. The electrical closed loop LO2 is formed by the paths W2, W9, W6, W10, W4, W8, W5, W7. The electrical closed loop LO3 is formed by the paths W3, W10, W6, W9.
[0140] As described above, in the present disclosure, when a certain electrical closed loop (1st closed loop) encloses other electrical closed loops (2nd closed loop), a part of the 1st closed loop and a part of the 2nd closed loop can also overlap. For example, in Figure 4 the 1st closed loop formed by the paths W4, W1, W2, W9, W6, W10 and the electrical closed loop LO1 as the 2nd closed loop overlap at the path W1, and the 1st closed loop encloses the 2nd closed loop.
[0141] In the present embodiment, the ring length of the electrically closed loop LO2 is the longest ring length among the electrically closed loops LO1, LO2, LO3. One example of the longest ring length is about 6 to 7 [mm].
[0142] Suppose that the maximum frequency fMAX of the transmission signal flowing to the terminal 4 is set to 10 GHz (10 10 Hz), then the wavelength λ of the maximum frequency fMAX of the transmission signal is λ = 3 x 10 8 / fMAX = 0.03 [m] = 30 [mm]. In the case where the longest ring length is 6 to 7 [mm], the longest ring length satisfies the condition that it is shorter than the wavelength λ of the maximum frequency fMAX.
[0143] In addition, the outer shield 1 constitutes an electrically closed loop LO4 that surrounds the terminal 4 without the aid of the inner shield 3. The electrically closed loop LO4 is formed by the paths W1, W2, W3, W4. That is, the cylindrical portion 10 (see Figure 5 ) in the outer shield 1 that is continuous in the circumferential direction D10 constitutes the electrically closed loop LO4. The electrically closed loop LO4 surrounds the electrically closed loops LO1, LO2, LO3.
[0144] Here, since the outer shield 1 is formed without a gap in the circumferential direction D10 of the cylindrical portion 10, the electrically closed loop LO4 is constituted by a single body. However, the outer shield 1 can constitute the electrically closed loop LO4 together with the conductor 170 and / or the conductor 180 of the circuit board 150. That is, in the case where the outer shield 1 is formed with a gap, the electrically closed loop LO4 can include a path formed by the conductor 170 and / or the conductor 180 that connects both ends of the gap. Here, the conductor 170 and / or the conductor 180 can not be included in the structure of the receptacle S1.
[0145] (2.2) Structure of plug
[0146] Next, the structure of the plug H1 of the present embodiment will be described. For the structure of the plug H1, the same structure as that of the receptacle S1 will be appropriately omitted from the description.
[0147] The plug H1 is bilaterally symmetrical with an axis that passes through the center of the plug H1 and extends in the up-down direction Dud as the axis of symmetry. As shown in Figure 9 , the plug H1 has an outer shield 5, a housing 6, a plurality of (two) inner shields 7, and a plurality of (eight) 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 on the outer side of the plurality of terminals 8. The plurality of inner shields 7 is disposed on the inner side of the outer shield 5. In addition, the plurality of inner shields 7 is disposed on the inner side of the housing 6.
[0148] The circuit board 550 (refer to Figure 9 ) is mechanically and electrically connected to the plug H1. The circuit board 550 has a base material 560 (refer to Figure 9 ) and conductors 570, 580 (refer to Figure 6 ) as the same structure as the base material 160 and the 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 side of the base material 560 on which the plug H1 is connected. In addition, in Figure 5 , the area where the conductor 580 (solder) is provided is illustrated by a two-dot chain line.
[0149] (2.2.1) Housing of Plug
[0150] The housing 6 is a resin molded body. The housing 6 has electrical insulation. 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 Dfb than in the left-right direction Dlr when viewed from above. The peripheral wall 62 protrudes in the downward direction Dd from the outer peripheral portion of the thickness direction side (lower surface) of the bottom wall 61. The left side surface and the right side surface of the housing 6 have a plurality of (two in the left side surface and two in the right side surface in Figure 6 ) notches 601 that penetrate the bottom wall 61 and the peripheral wall 62 in the up-down direction Dud. The plurality of notches 601 are provided at positions (refer to Figure 7 ) opposite to the board connecting portions 83 of the terminals 8 when viewed in the up-down direction Dud.
[0151] As shown in Figure 10 , the housing 6 also has two wall portions 65. Each wall portion 65 protrudes in the downward direction Dd from the bottom wall 61. The wall portion 65 has a shape of a rectangular parallelepiped with a lower surface curved in a cylindrical surface shape (refer to Figure 5 ). The front end and the rear end of the wall portion 65 are continuous with the peripheral wall 62. When viewed in the up-down direction Dud, the wall portion 65 is longer in the front-rear direction Dfb than in the left-right direction Dlr. That is, the wall portion 65 has a thickness in the direction along the left-right direction Dlr. The two wall portions 65 are arranged in the left-right direction Dlr.
[0152] Each wall portion 65 has a plurality of (two) receiving portions 68. The extension portions 72 of the inner side shield 7 are respectively received in the plurality of receiving portions 68. The plurality of receiving portions 68 are through holes provided in the wall portion 65. The receiving portion 68 penetrates the wall portion 65 in the up-down direction Dud. The receiving portion 68 also penetrates the bottom wall 61 in the up-down direction Dud. In addition, when viewed in the up-down direction Dud, the receiving portion 68 provided in the wall portion 65 is a recessed portion recessed from the side surface (a surface intersecting the left-right direction Dlr) of the wall portion 65.
[0153] In addition, each wall portion 65 has a plurality of (4) terminal holding portions 69. Each terminal holding portion 69 holds one terminal 8. The plurality of terminal holding portions 69 are recesses provided in the wall portion 65.
[0154] Multiple terminals 8 are embedded in the housing 6. In this embodiment, eight terminals 8 are fixed to the housing 6. The eight terminals 8 of the plug H1 correspond one-to-one with the eight terminals 4 of the socket S1. Each terminal 8 is positioned to connect with its corresponding terminal 4.
[0155] like Figure 6 , Figure 7 As shown, the bottom wall 61 has multiple (two) storage slots 613. Each storage slot 613 is a groove provided on the upper surface of the bottom wall 61. The storage slot 613 is longer in the left-right direction Dlr than in the front-back direction Dfb. The storage slot 613 houses the base 71 of the inner shielding member 7.
[0156] like Figure 5 As shown, the peripheral wall 62 has a plurality of (two) insertion portions 623. The plurality of (two) insertion portions 623 are recesses provided on the bottom surface (lower surface) of the peripheral wall 62. As will be described later, shielding protrusions 54, which are part of the outer shielding member 5, are inserted into the plurality of (two) insertion portions 623 respectively.
[0157] (2.2.2) External shielding of the plug
[0158] The outer shield 5 surrounds multiple terminals 8 and multiple inner shields 7. The outer shield 5 comprises a material such as metal as the main material or a plating layer forming the surface. Here, as an example, the outer shield 5 is formed primarily of metal. Figure 8 , Figure 10 As shown, the outer shield 5 has an outer peripheral wall 51, a plurality of (4) top walls 52, a plurality of (2) shield protrusions 54 and a bottom wall 55.
[0159] The outer peripheral wall 51 has a square cylindrical shape with a rectangular cross-section. The outer peripheral wall 51 includes two outer peripheral walls 511 and two outer peripheral walls 512. The two outer peripheral walls 511 are portions of the outer peripheral wall 51 that extend approximately parallel to the front-rear direction Dfb and are opposite each other in the left-right direction Dlr. The two outer peripheral walls 512 are portions of the outer peripheral wall 51 that extend approximately parallel to the left-right direction Dlr and are opposite each other in the front-rear direction Dfb. The two outer peripheral walls 512 connect the ends of the two outer peripheral walls 511 to each other.
[0160] The outer shield 5 also has a plurality of protrusions 56 protruding from the outer peripheral wall 51. The plurality of protrusions 56 function as contact portions that come into contact with the outer shield 1 of the object-side connector (here, the socket S1). The cylindrical portion 50 that is open at both ends in the up-down direction Dud is constituted by the outer peripheral wall 51, the top wall 52, and the plurality of protrusions 56. That is, the cylindrical portion 50 includes the outer peripheral wall 51, the top wall 52, and the plurality of protrusions 56. The outer peripheral surface 501 of the cylindrical portion 50 includes a portion of the outer peripheral surface of the outer peripheral wall 51 and the surfaces of the plurality of protrusions 56. The cylindrical portion 50 surrounds the hollow portion 50S.
[0161] The outer shield 5 of the connector (here, the plug H1) has a side surface (the outer peripheral surface 501) along the up-down direction Dud. The aforementioned side surface (the outer peripheral surface 501) has a convex configuration. That is, the configuration including the plurality of protrusions 56 corresponds to the convex configuration. The outer shield 5 of the connector (here, the plug H1) comes into contact with the outer shield 1 of the object-side connector (here, the socket S1) at the convex configuration (the plurality of protrusions 56). More specifically, the plurality of protrusions 56 come into contact with the inner peripheral surface 103 of the cylindrical portion 10 of the outer shield 1 (refer to FIG. 6). Figure 8
[0162] Compared to a case in which the outer peripheral surface 501 is planar without the plurality of protrusions 56, the outer shield 1 can be pressed into the outer shield 5 even if there is a slight deviation in the dimensions of the respective outer shields 1, 5. Thus, it is possible to reduce the likelihood of contact failure in which the outer shields 1, 5 come into contact with each other in one of the left-right direction Dlr or the front-back direction Dfb and are separated in the other of the left-right direction Dlr or the front-back direction Dfb, for example.
[0163] Three protrusions 56 are provided on each of the two outer peripheral walls 511. One protrusion 56 is provided on each of the two outer peripheral walls 512. The plurality of protrusions 56 are provided at intervals in the circumferential direction D50 of the cylindrical portion 50 that surrounds the hollow portion 50S (refer to FIG. 6). Figure 9 The maximum value of the creepage distances L2, L3 between the plurality of protrusions 56 is ¼ or less of the wavelength λ of the maximum frequency of the transmission signal flowing to the terminals 8. Thus, it is possible to reduce the likelihood of noise leaking from the region between the plurality of protrusions 56 (a region in the outer shield 5 that is not electrically connected to the outer shield 1). Here, the creepage distance L2 between the protrusion 56 provided on the outer peripheral wall 511 and the protrusion 56 provided on the outer peripheral wall 512 is greater than the creepage distance L3 between the plurality of protrusions 56 provided on the outer peripheral wall 511. That is, the maximum value of the creepage distances between the plurality of protrusions 56 is the creepage distance L2. Here, more specifically, the aforementioned maximum frequency is the maximum frequency of the transmission signal flowing to the high-frequency terminal 8T among the plurality of terminals 8. That is, in the present embodiment, the aforementioned maximum frequency is determined in accordance with the specifications of the high-frequency terminal 8T.
[0164] Each of the multiple (4) top walls 52 is L-shaped when viewed in the vertical direction Dud. The multiple (4) top walls 52 are connected to the lower ends of the four corners of the outer peripheral wall 51 and extend toward the inner side of the outer peripheral wall 51 when viewed in the vertical direction Dud.
[0165] The bottom wall 55 is rectangular when viewed along the vertical direction Dud. The bottom wall 55 is connected to the upper end of the outer peripheral wall 51 and extends outward from the outer peripheral wall 51 when viewed along the vertical direction Dud. The lower surface of the bottom wall 55 is formed to be parallel to the front-back direction Dfb and the left-right direction Dlr, and parallel to a plane perpendicular to the vertical direction Dud.
[0166] The inner peripheral surface of the outer peripheral wall 51 corresponds to the inner peripheral surface 503 of the cylindrical portion 50. Additionally, the outer shield 5 has a top surface 502. The top surface 502 is located at one of the two ends of the cylindrical portion 50 in the vertical direction Dud, becoming the target connector side (lower end) when transitioning from a non-connected state to a connected state between the connector (plug H1) and the target connector (socket S1). The top surface 502 is provided along the inner edge of the cylindrical portion 50. Here, the upper surface of the top wall 52 corresponds to the top surface 502. Furthermore, the inner edge of the top surface 502 corresponds to a portion of the inner edge of the cylindrical portion 50 at its lower end.
[0167] The boundary portion b3 between the top surface 502 and the outer peripheral surface 501 is an arc-shaped surface when viewed from the front-rear direction Dfb (see reference). Figure 7 Furthermore, the top surface 502 is defined here as the region on the outer surface of the cylindrical portion 50 where the acute angle formed with respect to the vertical direction Dud is 0 degrees or more and less than 45 degrees. The outer surface with the acute angle of 45 degrees or more is defined as the outer peripheral surface 501. The boundary portion b3 has a predetermined length along the circumferential direction D50 of the cylindrical portion 50.
[0168] Multiple (two) shielding protrusions 54 are provided, one for each of two of the multiple (four) top walls 52. Each shielding protrusion 54 protrudes upward from the corresponding top wall 52. The multiple (two) shielding protrusions 54 correspond to the multiple (two) insertion portions 623 (see reference) provided in the housing 6. Figure 8 A one-to-one correspondence. Each shielding protrusion 54 is inserted into the corresponding insertion part 623.
[0169] The outer shield 5 is fixed to the housing 6 by pressing it in. That is, the outer shield 5 is held by the housing 6 by being pressed in one direction (upward). At this time, the plurality of top walls 52 of the outer shield 5 cover at least a portion of the peripheral wall 62 of the housing 6. In addition, at this time, each shield protrusion 54 is inserted into the corresponding insertion part 623.
[0170] The outer shield 5 is formed seamlessly over its entire surface. In this embodiment, at least the outer peripheral surface 501 and the inner peripheral surface 503 of the outer shield 5 are seamless (i.e., without seams and cracks) over the entire circumferential direction D50 of the cylindrical portion 50.
[0171] like Figure 8 As shown, the outer peripheral surface 501 includes an outer surface 5110 (including the surface of the outer peripheral wall 511 and the surface of the protrusion 56) corresponding to the two outer peripheral walls 511 respectively, and an outer surface 5120 (including the surface of the outer peripheral wall 512 and the surface of the protrusion 56) corresponding to the two outer peripheral walls 512 respectively. The outer surfaces 5110 and 5120 are seamless. Furthermore, the two surfaces with different normal directions, namely the outer surfaces 5110 and 5120, are seamlessly connected. Thus, the outer peripheral surface 501 is seamless along the entire circumferential direction D50 of the cylindrical portion 50.
[0172] In addition, such as Figure 8 As shown, the inner circumferential surface 503 includes the inner surfaces 5111 of each of the two outer circumferential walls 511 and the inner surfaces 5121 of each of the two outer circumferential walls 512. The inner surfaces 5111 and 5121 are seamless. Furthermore, the two surfaces with different normal directions, namely the inner surfaces 5111 and 5121, are seamlessly connected. Thus, the inner circumferential surface 503 is seamless along the entire circumferential direction D50 of the cylindrical portion 50.
[0173] Furthermore, the boundary portion b3 between the outer peripheral surface 501 and the top surface 502 is seamless. For example, in Figure 9 At the upper right position of the paper (corner of the outer shield 5), the three surfaces with different normal directions, namely the outer surface 5110, the outer surface 5120 and the top surface 502, are seamlessly connected.
[0174] (2.2.3) Inner shielding of the plug
[0175] In this embodiment, the two inner shielding members 7 have the same shape. The inner shielding member 7 comprises metal as the main material or a material constituting a surface plating, etc. Here, as an example, the inner shielding member 7 is formed primarily of metal. Figure 7 As shown, the inner shield 7 has a base 71 and a plurality of (two) extensions 72.
[0176] The base 71 has a length along the left-right direction Dlr. The base 71 is plate-shaped. When viewed along the thickness direction (front-back direction Dfb) of the base 71, the base 71 is longer in the left-right direction Dlr than in the up-down direction Dud. The base 71 is housed in a receiving groove 613 provided on the bottom wall 61 of the housing 6.
[0177] The plurality of extension portions 72 protrude downward from the base portion 71. That is, the plurality of extension portions 72 protrude in the upward and downward direction Dud toward the side of the object side connector when transitioning from the non-connected state to the connected state of the connector (here, the plug H1) and the object side connector (here, the socket S1). The shape of each extension portion 72 is a rectangular plate shape. When viewed in the thickness direction (the front and back direction Dfb) of each extension portion 72, each extension portion 72 is longer in the upward and downward direction Dud than in the left and right direction Dlr. Furthermore, the thickness direction of each extension portion 72 can also be the left and right direction Dlr.
[0178] The extension portion 72 includes an abutting portion 720 (contact surface) that comes into contact with the inner side shield 3 of the object side connector (the socket S1). The abutting portion 720 is provided to a face (here, the left face or the right face) of the extension portion 72 along the length direction of the extension portion 72. The abutting portions 720 of the two extension portions 72 each face in a direction opposite to the other (the right direction Dr and the left direction Dl).
[0179] The plug H1 has two extension portions 72 for each of the two inner side shields 7. That is, the plug H1 has a total of four extension portions 72. The four housing portions 68 (refer to Figure 9 ) provided to the housing 6 correspond one-to-one with the four extension portions 72. Each extension portion 72 is housed in the corresponding housing portion 68.
[0180] The inner side shield 7 is fixed to the housing 6 by press-fitting. That is, the inner side shield 7 is held by the housing 6 by being press-fitted in one direction (downward). At this time, each extension portion 72 is housed in the corresponding housing portion 68. Here, the housing space of each of the two extension portions 72 in the shield holding portion (the housing portion 68) can also be larger than each extension portion 72 of the two extension portions 72.
[0181] As shown in Figure 9 , the base portion 71 of the inner side shield 7 is located at the upper end of the plug H1. Here, the outer side shield 5 has an end e5 and an end e6. The end e5 is the end (lower end) on the side of the object side connector when transitioning from the non-connected state to the connected state of the connector (here, the plug H1) and the object side connector (here, the socket S1). The end e6 is the end (upper end) on the side opposite to the end e5. Furthermore, here, the end e6 is provided as a region along the entire circumference of the circumferential direction D50 that surrounds the hollow portion 50S of the bottom wall 55 of the outer side shield 5. The outer side shield 5 opposes the two top end regions r7 of the inner side shield 7 in the region including the end e6.
[0182] The outer side shield 5 opposes at least one of the two top end regions r7 with a gap g7 in the region including the end e6. As shown in Figure 6As shown, the conductors 570, 580 of the circuit board 550 are electrically connected to the outer shield 5. In addition, the conductors 570, 580 are provided so as to span the two top end regions r7 of the inner shield 7 with the ends e6 of the outer shield 5, respectively. That is, the outer shield 5 is electrically connected to the inner shield 7 by means of the conductors 570, 580. On the other hand, in the state where the circuit board 550 is absent, the outer shield 5 is electrically insulated from at least one of the two top end regions r7 (both in the present embodiment) with the gap g7 therebetween. The shortest distance L7 between the outer shield 5 in the gap g7 and at least one of the two top end regions r7 is 0.01 mm or more and 0.1 mm or less.
[0183] The inner shield 7 has an end e7 and an end e8. The end e7 is an end (lower end) on the side of the object-side connector (in this case, the socket S1) when transitioning from a non-connected state to a connected state with the connector (in this case, the plug H1) and the object-side connector (in this case, the socket S1). The end e8 is an end (upper end) on the opposite side from the end e7. The inner shield 7 has a connection face 710 (upper face) that is electrically connected to the circuit board 550 at the end e8. The connection face 710 is planar and continuous across between the two top end regions r7. In more detail, the connection face 710 is a planar rectangle that connects between the two top end regions r7.
[0184] (2.2.4) Terminals of the plug
[0185] As shown in Figs. 2 and 3, the plurality of (eight) terminals 8 include a plurality of (six) low-frequency terminals 8P and a plurality of (two) high-frequency terminals 8T. The configuration of the plurality of terminals 8 is the same as that of the plurality of terminals 4 of the socket S1. That is, the contents explained in "(2.1.4.1) Configuration" also apply to the plurality of terminals 8. Figure 7 Figure 11 The shape of each terminal 8 is the same as that of the other terminals 8. Each terminal 8 is formed, for example, by blanking and bending processing of a metal plate, and the like. As shown in Fig. 4, each terminal 8 has a contact portion 81, a wraparound piece 82, a board connection portion 83, and a contact portion 84.
[0186] The shape of each terminal 8 is the same as that of the other terminals 8. Each terminal 8 is formed, for example, by blanking and bending processing of a metal plate, and the like. As shown in Fig. 4, each terminal 8 has a contact portion 81, a wraparound piece 82, a board connection portion 83, and a contact portion 84. Figure 6
[0187] The board connection portion 83 is electrically connected to the conductor 580 (solder) of the circuit board 550, for example. That is, the board connection portion 83 is joined to the circuit board 550 by a joining means such as soldering. Thereby, the circuit board 550 and the terminal 8 are mechanically and electrically connected. In addition, as shown in Fig. 3, the board connection portion 83 is surrounded by the outer shield 5 when viewed in the up-down direction Dud. Also, there is at least a portion of the board connection portion 83 and at least a portion of the outer shield 5 in one plane orthogonal to the up-down direction Dud. Figure 12
[0188] Contact portions 81 and 84 have a length in the vertical direction Du. Contact portion 81 is the portion that contacts contact portion 41 of terminal 4 of socket S1, and contact portion 84 is the portion that contacts contact portion 46 of terminal 4 of socket S1. The winding tab 82 is formed in an upward-opening U-shape. The winding tab 82 connects the lower end of contact portion 81 and the lower end of contact portion 84. The substrate connecting portion 83 is a portion that protrudes from the upper end of contact portion 81.
[0189] With terminal 8 held by housing 6, at least partially of contact portion 81 and contact portion 84 are exposed when viewed from below. Contact portion 81 and contact portion 84 contact corresponding terminals 4 among the plurality of terminals 4 (object-side terminals) of socket S1 (object-side connector) and are electrically connected to terminals 4 (see reference). Figure 7 ).
[0190] Terminal 8 also has a force-feeling part 85. The force-feeling part 85 generates a locking sensation when terminal 8 comes into contact with terminal 4 (the object-side terminal). The force-feeling part 85 is a protrusion that protrudes from the contact part 81. A locking sensation is generated when the force-feeling part 85 (protrusion) passes over the force-feeling part 47 of terminal 4.
[0191] The contact portion 84 has a recess 840 on the contact surface that contacts the contact portion 46. That is, the contact portion 46 is inserted into the recess 840. Here, the contact portion 46 contacts the side surface of the recess 840.
[0192] like Figure 6 As shown, the abutting portion 720 of the inner shield 7 and the contact portion 81 of at least one of the plurality of terminals 8 are arranged in the front-rear direction Dfb.
[0193] (2.2.5) Circuit board on the plug side
[0194] Plug H1 is electrically connected to conductor 580 (solder) of circuit board 550. Figure 13 The area on the upper surface of plug H1 with conductor 580 is shown by a dashed line. The configuration and electrical connection of conductors 570 and 580, outer shield 5, multiple inner shields 7, and multiple terminals 8 of circuit board 550 are the same as those of conductors 170 and 180, outer shield 1, multiple inner shields 3, and multiple terminals 4 of circuit board 150 corresponding to socket S1.
[0195] (2.2.6) Electrical closed loop of the plug
[0196] The configuration of the outer shield 5, multiple (two) inner shields 7, and multiple (eight) terminals 8 of plug H1 is consistent with... Figures 9-12The configuration of the outer side shield 1, the plurality of (two) inner side shields 3, and the plurality of (eight) terminals 4 of the illustrated receptacle S1 is the same. Therefore, in the plug H1 as well as in the receptacle S1, at least the plurality of (three) electrical closed loops LO1, LO2, LO3 are formed. The detailed explanation of the electrical closed loops LO1, LO2, LO3 of the plug H1 is the same as the detailed explanation of the electrical closed loops LO1, LO2, LO3 of the receptacle S1. In addition, the outer side shield 5, like the outer side shield 1, constitutes the electrical closed loop LO4 surrounding the terminals 8 without the aid of the inner side shield 7.
[0197] Here, since the outer side shield 5 is formed without a gap in the circumferential direction D50 of the cylindrical portion 50, the electrical closed loop LO4 is constituted by a single body. However, the outer side shield 5 can also constitute the electrical closed loop LO4 together with the conductor 570 and / or the conductor 580 of the circuit board 550. That is, in the case where the outer side shield 5 is formed with a gap, it can also be that a path connecting both ends of the gap is formed by the conductor 570 and / or the conductor 580, and the electrical closed loop LO4 includes this path. Here, it can also be that the conductor 570 and / or the conductor 580 are not included in the structure of the plug H1.
[0198] (3) Assembly Process
[0199] Next, one example of a process of connecting and assembling the connector device 100 by connecting the receptacle S1 and the plug H1 will be explained with reference to Figure 9
[0200] The circuit board 150 is mechanically and electrically connected to the receptacle S1. The circuit board 550 is mechanically and electrically connected to the plug H1. In this state, as shown in Figure 11 Figure 10 The receptacle S1 is disposed below the plug H1. Then, at least one of the action of the receptacle S1 moving upward and the action of the plug H1 moving downward is completed. Thereby, as shown in Figure 12 Figure 10 The receptacle S1 and the plug H1 are mechanically connected. In addition, as shown in Figure 12 The inner side shield 3 of the receptacle S1 and the inner side shield 7 of the plug H1 are in contact and electrically connected. In addition, as shown in Figure 10 The plurality of terminals 4 of the receptacle S1 and the plurality of terminals 8 of the plug H1 are in contact and electrically connected. In addition, as shown in Figure 12 Figure 10 The outer side shield 1 of the receptacle S1 and the outer side shield 5 of the plug H1 are in contact and electrically connected. In addition, as shown in Figure 10 Between the wall portion 25 and the wall portion 26 of the housing 2 of the receptacle S1 and between the wall portion 26 and the wall portion 27, the two wall portions 65 of the housing 6 of the plug H1 are inserted.
[0201] Here, when transitioning from the non-connected state to the connected state of the socket S1 and plug H1 (connector and object-side connector), the structures of the socket S1 and plug H1 come into contact with each other in the order described below.
[0202] First, the socket S1 and the plug H1 come into contact with each other at the outer shields 1 and 5. That is, the area near the upper end of the inner peripheral surface 103 of the cylindrical portion 10 of the outer shield 1 comes into contact with the area near the lower end of the outer peripheral surface 501 of the cylindrical portion 50 of the outer shield 5.
[0203] Next, the socket S1 and the plug H1 come into contact with each other at terminals 4 and 8. That is, at least one of the actions of contact 41 and contact 81 coming into contact with each other and contact 46 and contact 84 coming into contact with each other is completed.
[0204] Next, the socket S1 and the plug H1 come into contact with each other at the inner shields 3 and 7. That is, the abutting part 332 of the inner shield 3 and the abutting part 720 of the inner shield 7 come into contact with each other.
[0205] Next, the force-feeding part 47 (or 85) of the connector (socket S1 or plug H1) comes into contact with the target-side terminal (terminal 8 or 4). That is, at least one of the actions of the force-feeding part 47 contacting the contact part 81 of terminal 8 and the action of the force-feeding part 85 contacting the contact part 41 of terminal 4 is completed. Furthermore, a locking sensation is generated by the force-feeding parts 47 and 85.
[0206] Next, the outer shield 5 of the connector (here, plug H1) contacts the outer shield 1 of the target connector (here, socket S1) at the convex structure (multiple protrusions 56) (also called the contact portion). That is, the multiple protrusions 56 contact the inner circumferential surface 103 of the cylindrical portion 10 of the outer shield 1 (see reference). Figure 10 More specifically, firstly, the plurality of protrusions 56 contact the area near the upper end of the inner peripheral surface 103. Then, under the contact pressure between the plurality of protrusions 56 and the inner peripheral surface 103, while the outer shield 1 elastically deforms in a manner that the inner peripheral wall 13 of the outer shield 1 faces outward (towards the outer peripheral wall 11), the plurality of protrusions 56 further move downward. Finally, as... Figure 14 As shown, multiple protrusions 56 contact the region Dud along the vertical direction in the inner circumferential surface 103. Based on the above, the connection between the socket S1 and the plug H1 is completed.
[0207] Thus, the click feeling is generated at the terminals 4, 8 before the contact pressure and the frictional force between the outer shields 1, 5 become large by the plurality of protrusions 56 coming into contact with the outer shield 1. Therefore, the operator easily feels the click feeling compared to the case where the click feeling is generated after the plurality of protrusions 56 come into contact with the outer shield 1. That is, it is possible to suppress the case where the click feeling is not easily felt due to the frictional force. In addition, the positional relationship of the outer shields 1, 5 fixed by the plurality of protrusions 56 coming into contact with the outer shield 1 does not change in the subsequent processes, and thus it is possible to improve the accuracy of positioning. Thus, it is possible to secure the contact area between the outer shields 1, 5.
[0208] (4) Noise level
[0209] Figure 14 The solid line indicates the analysis result of the radiated noise of the connector device 100 of the embodiment, Figure 14 The broken line indicates the analysis result of the radiated noise of the connector device of the comparative example. The horizontal axis indicates the frequency (unit: [GHz]), and the vertical axis indicates the noise level (unit: [dBμV / m]).
[0210] In the connector device of the comparative example, the outer shields 1, 5 are formed by bending processing of a metal plate, unlike the connector device 100 of the embodiment, and the other structures are the same as those of the connector device 100 of the embodiment. Therefore, in the outer periphery surface and the inner periphery surface of each of the outer shields 1, 5, for example, the cylindrical portion 10 (50) of the connector device of the comparative example, there are joints or cracks on the circumferential direction D10 (D50) 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 processing of a metal. Therefore, the outer periphery surface and the inner periphery surface of the cylindrical portion 10 (50) of each of the outer shields 1, 5 are seamlessly formed (that is, formed in a manner that there are no joints and cracks) on the entire circumference of the circumferential direction D10 (D50) of the cylindrical portion 10 (50).
[0211] As shown in Figures 15-18 , the connector device 100 of the embodiment reduces the noise level compared to the connector device of the comparative example for each frequency. That is, in the embodiment, since the joints of each of the outer shields 1, 5 are removed, it is possible to obtain the effect of not only suppressing the influence of resonance but also reducing the noise radiated from the joints compared to the comparative example.
[0212] (Modified example 1)
[0213] The receptacle S2 and the plug H2 of the modified example 1 will be described below using Figure 15 . For the same structures as those of the embodiment, the same reference numerals are attached and the description is omitted. In addition, in the following description, Figure 17 ,Figure 15 In the figure, the area provided with the conductor 180, 580 (solder) is indicated by two-dot chain lines.
[0214] As shown in Figure 16 , Figure 17 , the socket S2 has only one inner shield 3. In addition, the socket S2 has only two terminals 4. Correspondingly, the shapes of the outer shield 1A and the housing 2A are different from those of the outer shield 1 and the housing 2 of the embodiment. The following will be described in more detail.
[0215] The outline shape of the housing 2A is the shape in which the area provided with the six low-frequency terminals 4P in the housing 2 of the embodiment is omitted. The outline shape of the outer shield 1A is the shape in which the area provided with the six low-frequency terminals 4P in the outer shield 1 of the embodiment is omitted.
[0216] The wall portion 25, the wall portion 26, and the wall portion 27 of the housing 2A each have one receiving portion 28. The three extension portions 32 of the inner shield 3 are received in these (three) receiving portions 28.
[0217] In addition, the wall portion 25 and the wall portion 27 each have one terminal holding portion 29. The wall portion 26 has two terminal holding portions 29. One of the two terminals 4 is held in the terminal holding portion 29 of the wall portion 25 and one of the terminal holding portions 29 of the wall portion 26. The other of the two terminals 4 is held in the terminal holding portion 29 of the wall portion 27 and the other of the terminal holding portions 29 of the wall portion 26.
[0218] Here, the two terminals 4 are high-frequency terminals 4T, but are not limited thereto, and at least one of the two terminals 4 can be a low-frequency terminal 4P.
[0219] The two high-frequency terminals 4T are arranged on both sides (front side and rear side) with the inner shield 3 interposed therebetween. Therefore, as with the embodiment, it is possible to reduce the possibility that transmission of noise occurs between the two high-frequency terminals 4T.
[0220] As shown in Figure 18 , Figure 19 , the plug H2 has only one inner shield 7. In addition, the plug H2 has only two terminals 8. Correspondingly, 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. The following will be described in more detail.
[0221] The outline shape of the housing 6A is the shape in which the area provided with the six low-frequency terminals 8P in the housing 6 of the embodiment is omitted. The outline shape of the outer shield 5A is the shape in which the area provided with the six low-frequency terminals 8P in the outer shield 5 of the embodiment is omitted.
[0222] The two wall portions 65 of the housing 6 each have one receiving portion 68. The two extended portions 72 of the inner shield 7 are received in these (two) receiving portions 68.
[0223] In addition, the two wall portions 65 each have one terminal holding portion 69. The terminal 8 is held in each terminal holding portion 69.
[0224] Here, the two terminals 8 are high-frequency terminals 8T, but are not limited thereto, and at least one of the two terminals 8 can be a low-frequency terminal 8P.
[0225] The two high-frequency terminals 8T are arranged on both sides (front side and rear side) with the inner shield 7 interposed therebetween. Therefore, as with the embodiment, it is possible to reduce the likelihood of transmission of noise occurring between the two high-frequency terminals 8T.
[0226] (Modified Example 2)
[0227] The receptacle S1 and the plug H1 of the modified example 2 will be described below using Figure 20 , Figure 19 . For structures common to the embodiment, the same reference numerals are annotated and the description is omitted. In addition, in Figure 20 , Figure 13 , only the two high-frequency terminals 4T and the two high-frequency terminals 8T of the receptacle S1 and the plug H1 are extracted and illustrated.
[0228] In the modified example 2, the shapes of the low-frequency terminal 4P and the high-frequency terminal 4T are different in the receptacle S1. In addition, the shapes of the low-frequency terminal 8P and the high-frequency terminal 8T are different in the plug H1.
[0229] That is, the receptacle S1 of the modified example 2 has a plurality of terminals 4. The plug 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 shape of the second terminal is different from the shape of the first terminal. The inner shield 3 (or 7) is arranged between the first terminal and the second terminal (see Figure 19 ).
[0230] As one example, the low-frequency terminal 4P is the same shape as the low-frequency terminal 4P of the embodiment. In addition, as one example, the low-frequency terminal 8P is the same shape as the low-frequency terminal 8P of the embodiment.
[0231] On the other hand, as one example, as shown in Figure 19 , the high-frequency terminal 4T of the modified example 2 has two contact portions 41, a base portion 42, and a board connecting portion 45. The high-frequency terminal 4T is formed, for example, by blanking and bending processing of a metal plate or the like.
[0232] The base portion 42 is formed in a letter U shape open to the upward direction Du. The substrate connecting portion 45 is connected to a lower end portion of the base portion 42. One contact portion 41 protrudes from a left end portion of the base portion 42 in the front-rear direction Dfb, and the other contact portion 41 protrudes from a right end portion of the base portion 42 in the front-rear direction Dfb.
[0233] As one example, as shown in Figure 20 , the high-frequency terminal 8T has two contact portions 81, a base portion 86, and a substrate connecting portion 83. The high-frequency terminal 8T is formed, for example, by blanking and bending processing of a metal plate.
[0234] The base portion 86 is formed in a letter U shape open to the downward direction Dd. The substrate connecting portion 83 is connected to an upper end portion of the base portion 86. One contact portion 81 protrudes from a left end portion of the base portion 86 in the left direction Dl, and the other contact portion 81 protrudes from a right end portion of the base portion 86 in the right direction Dr.
[0235] In the process of connecting the socket S1 and the plug H1, as shown in Figure 21 , each high-frequency terminal 4T and the corresponding high-frequency terminal 8T are connected. That is, the high-frequency terminal 8T is inserted between the two contact portions 41 of the high-frequency terminal 4T. Thus, the two contact portions 41 each come into contact with the corresponding contact portion 81. In addition, at this time, the interval of the two contact portions 41 is pressed apart in the left-right direction Dlr.
[0236] Further, the shapes of the terminals 4, 8 can also be as follows. Since the low-frequency terminal 4P (8P) is likely to be connected to the power supply wiring and the ground portion, the low-frequency terminal 4P (8P) can also be made wider than the high-frequency terminal 4T (8T) to have a low resistance. In addition, the contact area between the low-frequency terminal 4P and the low-frequency terminal 8P can also be made larger than the contact area between the high-frequency terminal 4T and the high-frequency terminal 8T to make the low-frequency terminal 4P, 8P have a low resistance. In addition, in order to pass a high-speed signal through the high-frequency terminal 4T (8T), the high-frequency terminal 4T (8T) can also be made to have a characteristic impedance that matches the characteristic impedance of the signal line formed on the circuit substrate 150 (550).
[0237] In addition, it can also be that the shape of the low-frequency terminal 4P (8P) is different from the shape of the high-frequency terminal 4T (8T) in only one of the socket S1 and the plug H1.
[0238] (Other Modification Examples of the Embodiment)
[0239] Other modification examples of the embodiment are listed below. The following modification examples can also be realized by appropriate combination. In addition, the following modification examples can also be realized by appropriate combination with the above-described modification example 1.
[0240] The manner in which the outer shield 1 (5) and the inner shield 3 (7) are electrically connected to each other by the conductor 180 (580) of the circuit board 150 (550) is not limited. The outer shield 1 (5) and the inner shield 3 (7) can be electrically connected to each other by other electrically conductive members.
[0241] Alternatively, at least one of the outer shield 1 (5), the plurality of inner shields 3 (7), and the plurality of terminals 4 (8) can be in contact with the conductor 170 (570), thereby being electrically connected to the conductor 170 (570).
[0242] As shown in FIG. 1, for example, the inner shield 3 (7) can be directly joined to the outer shield 1 (5) at the top end region r1 (r7) of the inner shield 3 (7). Figure 21 As shown in FIG. 1, for example, the inner shield 3 (7) can be directly joined to the outer shield 1 (5) at the top end region r1 (r7) of the inner shield 3 (7). Alternatively, the inner shield 3 (7) can be joined to the outer shield 1 (5) by welding, press-fitting, or riveting. Alternatively, the inner shield 3 (7) and the outer shield 1 (5) can be formed by one member. Alternatively, the inner shield 3 (7) and the outer shield 1 (5) can be seamlessly joined.
[0243] The extension 32 (or 72) is not limited to protruding from the base 31 (or 71) in the up-down direction Dud. For example, the extension 32 (or 72) can protrude from the base 31 (or 71) in the front-back direction Dfb.
[0244] The number of each structure of the embodiment is one example and is not limited to the number shown in the embodiment. For example, the number of the extension 32 (72) of the inner shield 3 (7) can be appropriately changed. In addition, the number of the terminal 4 (8) of each connector (the socket S1 and the header H1) can be appropriately changed. In addition, each connector can have only the low-frequency terminal 4P (8P) as the terminal 4 (8) or can have only the high-frequency terminal 4T (8T) as the terminal 4 (8).
[0245] The portion formed as a recess or a depression in the embodiment can be appropriately replaced with a through-hole. Conversely, the portion formed as a through-hole in the embodiment can be appropriately replaced with a recess or a depression.
[0246] In the embodiment, the portion joined by press-fitting can be joined by insert molding. Conversely, in the embodiment, the portion joined by insert molding can be joined by press-fitting. In addition, other joining methods such as adhesion, welding, or riveting can be used instead of press-fitting or insert molding.
[0247] Alternatively, instead of drawing processing, the outer side shield 1, 5 is formed by, for example, molding, whereby at least a part of the surface of the outer side shield 1, 5 (for example, the entire outer peripheral surface 101, 501) is formed seamlessly. Alternatively, at least a part of the surface of the outer side shield 1, 5 is formed seamlessly by, for example, welding.
[0248] Alternatively, the plurality of protrusions 56 of the outer side shield 5 can be provided to the inner peripheral surface 503 instead of the outer peripheral surface 501 of the cylindrical portion 50.
[0249] Alternatively, the structure of a part of the receptacle S1 of the embodiment is appropriately applied to the plug H1. Conversely, the structure of a part of the plug H1 of the embodiment is appropriately applied to the receptacle S1. For example, the plurality of protrusions 56 can be provided to both of the outer side shields 1, 5, or only to the outer side shield 1 among the outer side shields 1, 5.
[0250] In the embodiment, the terms indicating the directions of the up-down direction, the front-rear direction, the left-right direction, and the like indicate only the relative directions determined by the relative positional relationship of the structure members of the connector and the object side connector, and do not indicate absolute directions such as the vertical direction.
[0251] (SUMMARY)
[0252] The following technical solutions are disclosed according to the above-described embodiment and the like.
[0253] The connector (the receptacle S1, S2 or the plug H1, H2) of the first technical solution has a plurality of terminals (4 or 8). The plurality of terminals (4 or 8) are electrically connected to a plurality of object side terminals of an object side connector, respectively. The connector further has a housing (2, 2A or 6, 6A) and an inner side shield (3 or 7). The housing (2, 2A or 6, 6A) holds the plurality of terminals (4 or 8). The connector and the object side connector are connected to each other by at least one of moving toward the other in a first direction (an up-down direction Dud). The plurality of terminals (4 or 8) includes two terminals (4 or 8). The two terminals (4 or 8) are disposed on both sides across the inner side shield (3 or 7) in a second direction (a front-rear direction Dfb) orthogonal to the first direction. The inner side shield (3 or 7) has a base portion (31 or 71) and an extension portion (32 or 72). The base portion (31 or 71) has a length in a direction along a third direction (a left-right direction Dlr) orthogonal to both the first direction and the second direction. The extension portion (32 or 72) protrudes from the base portion (31 or 71). The housing (2, 2A or 6, 6A) has a shield holding portion (a receiving portion 28 or 68). The shield holding portion (the receiving portion 28 or 68) holds the extension portion (32 or 72).
[0254] According to the above-described structure, the two terminals (4 or 8) are arranged on both sides of the inner shield (3 or 7) through the two terminals (4 or 8), so that the possibility of transmission of noise occurring between the two terminals (4 or 8) can be reduced compared to the case where the inner shield (3 or 7) is not present. Also, since the extension portion (32 or 72) of the connector is positioned by the shield holding portion (receiving portion 28 or 68), the accuracy of alignment between the extension portion (32 or 72) of the connector and the object side connector can be improved.
[0255] In addition, according to the first technical solution, in the connector (receptacle S1, S2 or plug H1, H2) of the second technical solution, the extension portion (32 or 72) protrudes in the first direction toward the orientation of the object side connector when transitioning from the non-connected state of the connector and the object side connector to the connected state.
[0256] According to the above-described structure, compared to the case where the extension portion (32 or 72) protrudes in the second direction, for example, the space occupied by the extension portion (32 or 72) when viewed in the first direction can be reduced.
[0257] In addition, according to the second technical solution, in the connector (receptacle S1, S2 or plug H1, H2) of the third technical solution, the housing (2, 2A or 6, 6A) has a wall portion (25, 26, 27 or 65). The wall portion (25, 26, 27 or 65) has a thickness in the direction along the third direction. The wall portion (25, 26, 27 or 65) has a receiving portion (28 or 68) as a shield holding portion. The extension portion (32 or 72) is received in the receiving portion (28 or 68).
[0258] According to the above-described structure, the insulation distance of the extension portion (32 or 72) can be ensured by the housing (2, 2A or 6, 6A).
[0259] In addition, according to any one of the first technical solution to the third technical solution, in the connector (receptacle S1, S2 or plug H1, H2) of the fourth technical solution, the extension portion (32 or 72) includes an abutting portion (332 or 720). The abutting portion (332 or 720) is in contact with the inner shield of the object side connector.
[0260] By adopting the above-described structure and the extension portion (32 or 72) of the connector being positioned by the shield holding portion (receiving portion 28 or 68), the accuracy of electrical connection between the inner shield (3 or 7) of the connector and the inner shield of the object side connector can be improved.
[0261] In addition, according to the fourth aspect, in the connector (the sockets S1, S2) of the fifth aspect, the extension portion (the first extension portion 33) further includes an extension portion main body (331). The extension portion main body (331) protrudes from the base portion (31). The abutting portion (332) protrudes from the extension portion main body (331).
[0262] According to the above structure, since the abutting portion (332) of the connector protrudes from the extension portion main body (331), it is possible to reduce the possibility that the extension portion (the first extension portion 33) of the connector contacts the inner side shield of the object side connector at a portion other than the abutting portion (332).
[0263] In addition, according to the fourth aspect or the fifth aspect, in the connector (the sockets S1, S2 or the plugs H1, H2) of the sixth aspect, the extension portion (32 or 72) has a plate shape. The abutting portion (332 or 720) is provided to a face of the extension portion (32 or 72) along a length direction of the extension portion (32 or 72).
[0264] According to the above structure, it is possible to secure a contact area between the abutting portion (332 or 720) of the connector and the inner side shield of the object side connector.
[0265] In addition, according to any one of the fourth aspect to the sixth aspect, in the connector (the sockets S1, S2 or the plugs H1, H2) of the seventh aspect, the plurality of terminals (4 or 8) each include a contact portion (41, 46 or 81, 84). The contact portion (41, 46 or 81, 84) contacts the object side terminal. The abutting portion (332 or 720) and the contact portion (41, 46 or 81, 84) of at least one terminal (4 or 8) of the plurality of terminals (4 or 8) are arranged in the second direction.
[0266] According to the above structure, it is possible to simply realize the configuration of the connector.
[0267] In addition, according to any one of the first aspect to the seventh aspect, in the connector (the sockets S1, S2 or the plugs H1, H2) of the eighth aspect, the inner side shield (3 or 7) has a plurality of extension portions (32 or 72).
[0268] According to the above structure, it is possible to further improve the accuracy of the alignment between the extension portion (32 or 72) of the connector and the object side connector.
[0269] Further, according to the eighth aspect, in the connector (sockets S1, S2) of the ninth aspect, the plurality of extension portions (32) include a first extension portion (33) and a second extension portion (34). The first extension portion (33) includes an abutting portion (332). The abutting portion (332) contacts an inner side shield of the object side connector. The second extension portion (34) is held by the shield holding portion (receiving portion 28).
[0270] According to the above structure, compared with a case where the plurality of extension portions (32) include only the first extension portion (33), the number of extension portions (32) can be increased, and thus the accuracy of alignment between the extension portion (32) of the connector and the object side connector can be further improved.
[0271] Further, according to the ninth aspect, in the connector (sockets S1, S2) of the tenth aspect, the receiving space of the first extension portion (33) in the shield holding portion (receiving portion 28) is larger than the first extension portion (33).
[0272] According to the above structure, the allowable error in alignment between the first extension portion (33) of the connector and the object side connector is large.
[0273] Further, according to any one of the first aspect to the tenth aspect, in the connector (sockets S1, S2 or plugs H1, H2) of the eleventh aspect, an outer side shield (1, 1A or 5, 5A) is further provided. The outer side shield (1, 1A or 5, 5A) surrounds the plurality of terminals (4 or 8) and the inner side shield (3 or 7).
[0274] According to the above structure, the possibility of transmission of noise occurring between the inside and the outside of the outer side shield (1, 1A or 5, 5A) can be reduced.
[0275] Further, according to the eleventh aspect, in the connector (sockets S1, S2 or plugs H1, H2) of the twelfth aspect, the inner side shield (3 or 7) includes two tip end regions (r1 or r7). The outer side shield (1, 1A or 5, 5A) has a first end (e1 or e5) and a second end (e2 or e6) on the side opposite to the first end (e1 or e5). The first end (e1 or e5) is an end on the object side connector side when transitioning from a non-connected state to a connected state of the connector and the object side connector. The outer side shield (1, 1A or 5, 5A) opposes at least one of the two tip end regions (r1 or r7) with a gap (g1 or g7) in a region including the second end (e2 or e6).
[0276] According to the above-described structure, since at least a part of the inner shield (3 or 7) is provided on the second end (e2 or e6) side, it is possible to reduce the possibility of transmission of noise occurring on the second end (e2 or e6) side.
[0277] In addition, according to the 12th aspect, in the connector (the socket S1, S2 or the plug H1, H2) of the 13th aspect, the outer shield (1, 1A or 5, 5A) is electrically insulated from at least one of the two tip end regions (r1 or r7) with the gap (g1 or g7) in a state where the circuit board (150 or 550) is not present. The circuit board (150 or 550) is electrically connected to the outer shield (1, 1A or 5, 5A).
[0278] According to the above-described structure, compared to the case where the outer shield (1, 1A or 5, 5A) and the two tip end regions (r1 or r7) are in contact, it is possible to improve the dimensional tolerance of each of the outer shield (1, 1A or 5, 5A) and the inner shield (3 or 7).
[0279] With respect to the structure other than the 1st aspect, the structure that is not necessary for the connector (the socket S1, S2 or the plug H1, H2) can be appropriately omitted.
[0280] In addition, the connector device (100) of the 14th aspect has the connector (the socket S1, S2 or the plug H1, H2) of any one of the 1st to 13th aspects and the object side connector.
[0281] According to the above-described structure, by disposing the two terminals (4 or 8) on both sides with the inner shield (3 or 7) in between, it is possible to reduce the possibility of transmission of noise occurring between the two terminals (4 or 8) compared to the case where the inner shield (3 or 7) is not present. Also, since the extension portion (32 or 72) of the connector is positioned by the shield holding portion (the housing portion 28 or 68), it is possible to improve the accuracy of alignment between the extension portion (32 or 72) of the connector and the object side connector.
