In the drawings other than FIG. 15 to FIG. 18, the first circuit board 92 and the second circuit board 91 are omitted for convenience.

[0012] As shown in FIG. 1, the second connector 1 is configured to be fitted to the first connector 5 by moving in one direction on the first axis A1 toward the first connector 5 relative to the first connector 5. Hereinafter, the direction in which the first connector 5 and the second connector 1 are fitted together (the direction along the first axis A1) may be referred to as the up-down direction. Hereinafter, when the first connector 5 and the second connector 1 are fitted together along the up-down direction, the side on which the first connector 5 is located may be referred to as the "bottom" and the side on which the second connector 1 is located may be referred to as the "top". That is, the second connector 1 is configured to be connected to the first connector 5 from above along the first axis A1 toward the first connector 5 relative to the first connector 5. However, the specification of these directions is not intended to limit the use mode of the connector device 100. Hereinafter, the state in which the first connector 5 and the second connector 1 are fitted together (see FIG. 2) will be referred to as the "fitted state".

[0013] In the following description, the two axes perpendicular to the first axis A1 are referred to as the second axis A2 and the third axis A3. As shown in Fig. 1, the second axis A2 is an axis along the longitudinal direction of the connector device 100. The third axis A3 is an axis along the lateral direction of the connector device 100.

[0014] The connector device 100 of this embodiment includes a first connector 5 and a second connector 1.

[0015] The first connector 5 has a first housing 6, a first terminal 7, and a first shield 8. The first terminal 7 is held in the first housing 6. The first shield 8 is held in the first housing 6.

[0016] As shown in Figs. 9 and 12, the second connector 1 has a second housing 9, a second terminal 3, and a second shield 4. The second terminal 3 has a second specific terminal 31 and a second connection terminal 32 held in the second housing 9. The second shield 4 has a second outer shield 41 and a second inner shield 45. The second outer shield 41 surrounds the second specific terminal 31 and the second connection terminal 32 in a rectangular shape. The second inner shield 45 is disposed between the second specific terminal 31 and the second connection terminal 32.

[0017] As shown in FIG. 4 and FIG. 7, the first connector 5 has a first housing 6, a first terminal 7, and a first shield 8. The first terminal 7 is held by the first housing 6, and has a first specific terminal 71 and a first connection terminal 72 that contact the second specific terminal 31 and the second connection terminal 32, respectively, in a mated state in which the first connector 5 and the second connector 1 are mated. The first shield 8 has a first outer shield 81 and a first inner shield 85. The first outer shield 81 surrounds at least one of the first specific terminal 71 and the first connection terminal 72. The first inner shield 85 is disposed between the first specific terminal 71 and the first connection terminal 72.

[0018] 12, the second outer shield 41 has a pair of second horizontal shields 401 facing each other along a third axis A3 perpendicular to the first axis A1, and a second vertical shield 402 disposed at an end of the pair of second horizontal shields 401. As shown in Fig. 11, the second inner shield 45 has a second inner shield extension 453. The second inner shield extension 453 has a second inner shield lower end 451 located below the first axis A1, and a second inner shield upper end 452 located above the second inner shield lower end 451.

[0019] 13A and 13B, the second specific terminal 31 has a second specific terminal connection piece 314, a second specific terminal contact piece 313, and a second specific terminal linking portion 312. The second specific terminal connection piece 314 is disposed at an upper portion in the second connector 1. The second specific terminal contact piece 313 has a curved second specific terminal curved portion 316, and when the first specific terminal 71 contacts the convex surface of the second specific terminal curved portion 316, the second specific terminal contact piece 313 is elastically deformed toward one of the pair of second horizontal shields 401. The second specific terminal linking portion 312 links the second specific terminal connection piece 314 and the second specific terminal contact piece 313.

[0020] As shown in FIG. 6, the first inner shield 85 has a first inner shield extension 853. The first inner shield extension 853 has a first inner shield upper end 851 and a first inner shield lower end 852. The first inner shield upper end 851 is located above in the mated state. The first inner shield lower end 852 is located below the first inner shield upper end 851. As shown in FIG. 16, the second inner shield extension 453 and the first inner shield extension 853 contact each other on the third axis A3 in the mated state. The second specific terminal 31 is surrounded by a pair of the second horizontal shield 401, the second vertical shield 402, and the second inner shield 45.

[0021] 20A and 20B, the connector device 100 has a first normal posture when the second connector 1 and the first connector 5 move relative to each other to mate with each other. In the first normal posture, each of the pair of second horizontal shields 401 contacts the first outer shield 81, the second inner shield extension 453 contacts the first inner shield extension 853, and the second specific terminal 31 and the first specific terminal 71 are spaced apart from each other.

[0022] As shown in Figures 21A, 21B and 21C, in the connector device 100, when the first outer shield 81 is in contact with one of a pair of second horizontal shields 401 and spaced apart from the other, and the second inner shield extension 453 and the first inner shield extension 853 are in contact with each other, the second specific terminal 31 and the first specific terminal 71 are spaced apart.

[0023] In the connector device 100 of this embodiment, when the second connector 1 and the first connector 5 are mated, even if the first outer shield 81 is in an inclined position in which it contacts one of the pair of second horizontal shields 401 and moves away from the other, the first inner shield 85 and the second inner shield 45 can come into contact with each other before the second specific terminal 31 and the first specific terminal 71 come into contact with each other. Therefore, even if one of the first specific terminal 71 and the second specific terminal 31 is more likely to undergo plastic deformation than the other terminal when mating, the plastic deformation of the one terminal due to the other terminal can be suppressed. Therefore, the occurrence of malfunctions when mating the first connector and the second connector can be suppressed.

[0024] (2)Details The connector device 100 of this embodiment will be described in more detail below with reference to the drawings.

[0025] The connector device 100 includes a first connector 5 and a second connector 1. The second connector 1 fits with the first connector 5 from above the first axis A1.

[0026] (2.1) First Connector As shown in FIGS. 1 and 4, the first connector 5 has a first housing 6, a first terminal 7, and a first shield 8.

[0027] 4 to 7, the first connector 5 is a socket (female connector) and includes a first housing 6, a plurality of (here, eight) first terminals 7, and a first shield 8. The first terminals 7 are held in the first housing 6.

[0028] (2.1.1) First Housing 5, the first housing 6 is made of an insulating resin material and is formed in a flat, generally rectangular parallelepiped shape that is long along the second axis A2. In the first housing 6, both sides of the third axis A3 in the central portion of the second axis A2 are cut out in a generally rectangular shape when viewed from the first axis A1. In addition, in the first housing 6, both sides of the third axis A3 in the central portion of the second axis A2 are cut out in a generally rectangular shape when viewed from the first axis A1.

[0029] As shown in FIG. 5, the first housing 6 has a first inner bottom wall 66, a first inner wall 67, a first outer bottom wall 60, a first outer peripheral wall 64, and a first wall portion 61. The first inner bottom wall 66, the first inner wall 67, the first outer bottom wall 60, the first outer peripheral wall 64, and the first wall portion 61 are integrally formed. The first wall portion 61 protrudes upward from the first outer bottom wall 60 and the first inner bottom wall 66 along the first axis A1. The first wall portion 61 has a pair of side surfaces 612 disposed on both sides of an upper surface 610 along a third axis A3 perpendicular to the first axis A1 and the second axis A2. At least one of the first inner bottom wall 66 and the first outer bottom wall 60 may be referred to as a first bottom wall.

[0030] The first inner bottom wall 66 is in the form of a rectangular plate that is long along the second axis A2.

[0031] The first inner side walls 67 protrude upward from the periphery of the first inner bottom wall 66. The first inner side walls 67 are a pair of walls that are long along the second axis A2. The pair of first inner side walls 67 are provided near the center of the second axis A2 at both ends of the first inner bottom wall 66 along the third axis A3.

The first outer peripheral wall 64 is a rectangular frame shape with the center portions of each of the four sides cut out when viewed from the first axis A1 (hereinafter also referred to as "plan view"). The first outer peripheral wall 64 extends in the circumferential direction.

[0034] The first wall portion 61 has a rectangular parallelepiped shape that is elongated along the second axis A2, and protrudes upward from the center of the first inner bottom wall 66. An area surrounded by the inner bottom surface of the first inner bottom wall 66, the inner side surface of the first inner wall 67, and the outer surface of the first wall portion 61 forms a recess 601 into which the second connector 1 fits. Specifically, a second inner circumferential wall 902 of the second connector 1 is disposed in the recess 601.

[0035] An area surrounded by the end face of the first inner wall 67 on the second axis A2, the inner bottom surface of the first outer bottom wall 60, and the inner surface of the first outer peripheral wall 64 constitutes a recess 602. In the recess 602, a second outer peripheral wall 905 of the second connector 1 is disposed when the first connector 5 and the second connector 1 are mated.

[0036] The first housing 6 holds a plurality of first terminals 7 and a first shield 8 .

[0037] As shown in FIG. 4, in this embodiment, some (six) of the first terminals 7 (first connection terminals 72) among the plurality (eight) of first terminals 7 are arranged across the first inner side wall 67 and the housing recess 615 (see FIG. 5) of the first wall portion 61. Specifically, three first connection terminals 72 are arranged on each of the pair of first inner side walls 67. In this embodiment, the remaining first terminals 7 (first specific terminals 71) among the plurality (eight) of first terminals 7 are arranged on the first wall portion 61 and held by the first housing 6. The first specific terminals 71 are arranged on the upper surface 610, the end surface 611, and the side surface 612 of the first wall portion 61 at both ends of the second axis A2 of the first wall portion 61.

[0038] 4, in this embodiment, the first outer shield 81 of the first shield 8 is adjacent along the first outer peripheral wall 64. Also, in this embodiment, the first inner shield 85 of the first shield 8 is disposed in a slot 69 (see FIG. 5) formed in the first housing 6.

[0039] (2.1.2) 1st terminal The first terminals 7 have terminals for transmitting signals and are formed by bending a strip-shaped metal plate. The first terminals 7 are gold-plated. The first terminals 7 come into contact with the second terminals 3 of the second connector 1, respectively, when the first connector 5 and the second connector 1 are in a mated state.

[0040] The first terminal 7 has a first connection terminal 72 and a first specific terminal 71 .

[0041] The multiple first terminals 7 include one or more first specific terminals 71. The multiple first terminals 7 also include one or more terminals (first connection terminals 72) other than the first specific terminals 71. Here, of the eight first terminals 7, two are first specific terminals 71 and the remaining six are first connection terminals 72.

[0042] The two first specific terminals 71 are disposed on both ends of the second axis A2 within the first connector 5. Each of the two first specific terminals 71 is disposed between both ends of the first wall portion 61.

[0043] The six first connection terminals 72 are arranged on the second axis A2 in a region between the two first specific terminals 71, with three terminals on each side of the third axis A3. The six first connection terminals 72 are held by each of the pair of first inner side walls 67, three terminals each.

[0044] The first specific terminals 71 are terminals for transmitting signals. The two first specific terminals 71 have the same shape.

[0045] The first connection terminal 72 has a terminal for transmitting a signal. Some or all of the multiple (e.g., six) first connection terminals 72 may be terminals for transmitting power. The six first connection terminals 72 have the same shape. The first connection terminals 72 may have terminals with different shapes.

[0046] The first specific terminal 71 is a terminal for transmitting a signal. Specifically, a high-frequency signal having a higher frequency than the signal transmitted to the first connection terminal 72 is transmitted to the first specific terminal 71.

[0047] (2.1.2.1) First specific terminal In the fitted state, the first specific terminal 71 comes into contact with the second specific terminal 31 and is connected to the second specific terminal 31 .

[0048] As shown in FIG. 8A, the first specific terminal 71 has a first specific terminal connection piece 714, a first specific terminal contact piece 713, and a first specific terminal linking portion 712, which are integrally formed. In this embodiment, the first specific terminal 71 has a pair of first specific terminal contact pieces 713 (a first contact piece 7136 and a second contact piece 7137). The first specific terminal connection piece 714 is disposed below the first axis A1 of the first connector 5. The first specific terminal contact piece 713 contacts the second specific terminal 31 when the first connector 5 and the second connector 1 are in a mated state. The first specific terminal linking portion 712 links the first specific terminal connection piece 714 and the first specific terminal contact piece 713 (the first contact piece 7136 and the second contact piece 7137).

[0049] Specifically, the first specific terminal contact piece 713 (the first contact piece 7136 and the second contact piece 7137) are connected to both ends of the third axis A3 of the first specific terminal linking portion 712. The first specific terminal connecting piece 714 is connected to a side end of the second axis A2 of the first specific terminal linking portion 712.

[0050] The first specific terminal connecting portion 712 has a curved first specific terminal curved portion 716. The first specific terminal curved portion 716 is formed from the end of the first specific terminal connecting portion 712 along the third axis A3 to the first specific terminal contact piece 713.

[0051] The first specific terminal connector 712 has an upper portion 7120 and a terminal extension portion 7121. As shown in Fig. 8B, the upper portion 7120 is disposed on at least the upper surface 610 of the end portion of the second axis A2 of the first wall portion 61. The first specific terminal connector 712 is fixed to the first wall portion 61 (see Figs. 1 and 18).

[0052] The terminal extension portion 7121 extends downward from the upper portion 7120 along one end face (outer surface) 611 of the end portion of the second axis A2 of the first wall portion 61. The terminal extension portion 7121 has an end 7122 on the downward side.

[0053] The terminal extension 7121 has an outer surface 7124. As shown in FIG. 8B, the outer surface 7124 is provided on the same plane as the surface of the end of the first wall 61 or outward from the surface of the first wall 61. "The outer surface 7124 of the terminal extension 7121 is provided outward from the surface of the first wall 61" means, for example, that a part of the terminal extension 7121 protrudes from the first wall 61 in the second axis A2 when viewed along the third axis A3. At least one of the upper portion 7120 or the terminal extension 7121 (for example, a joint portion) has a curved surface 7123. The curved surface 7123 has an outer surface 7124 that is provided on the same plane as the surface of the first wall 61 or outward from the surface of the first wall 61.

[0054] 8D, the first specific terminal coupling portion 712 has a main body portion 715 extending upward from the first specific terminal connection piece 714. The maximum distance P1 between the main body portion 715 and the first vertical shield 802 on the second axis A2 is greater than the minimum distance P2 between the terminal extension portion 7121 and the first vertical shield 802 on the second axis A2.

[0055] 18, the first specific terminal linking portion 712 has a main body portion 715 extending upward from the first specific terminal connecting piece 714. In the fitted state, a maximum distance P3 between the main body portion 715 and the second vertical shield 402 on the second axis A2 is larger than a minimum distance P4 between the terminal extension portion 7121 and the second vertical shield 402 on the second axis A2.

[0056] As shown in FIG. 8A, the first specific terminal connection piece 714 is a substantially rectangular plate-like shape when viewed along the first axis A1. The first specific terminal connection piece 714 protrudes from the first specific terminal linking portion 712 along the second axis A2. The first specific terminal connection piece 714 is connected to the first specific terminal linking portion 712 between the portions where the pair of first specific terminal contact pieces 713 are connected (both ends on the third axis A3). The first specific terminal connection piece 714 has a substantially rectangular flat portion (flat portion) having a thickness on the first axis A1. The flat portion is connected to the main body portion 715. The main body portion 715 positions the lower surface of the flat portion of the first specific terminal connection piece 714 lower than the lower surface of the first specific terminal linking portion 712. The first specific terminal connection piece 714 (flat portion) is configured to be connected to the first circuit board 92.

[0057] The first specific terminal contact piece 713 is a portion of the first specific terminal 71 that comes into contact with the second specific terminal 31. The pair of first specific terminal contact pieces 713 (first contact piece 7136 and second contact piece 7137) protrude downward from both ends of the first specific terminal connecting portion 712 on the third axis A3. The first specific terminal contact piece 713 is formed in a substantially rectangular flat plate shape having a thickness on the third axis A3. The pair of first specific terminal contact pieces 713 are arranged side by side on the third axis A3.

[0058] The first specific terminal contact piece 713 has a contact piece first surface 7131, a contact piece second surface 7132, and a contact piece side end surface 7133. The contact piece first surface 7131 is a surface that contacts the second specific terminal 31. The contact piece second surface 7132 is disposed on the opposite side to the contact piece first surface 7131 and adjacent to one of a pair of side surfaces 612 at the end of the first wall portion 61. The contact piece second surfaces 7132 of the pair of first specific terminal contact pieces 713 face each other on the third axis A3. The contact piece side end surface 7133 is a surface that connects the contact piece first surface 7131 and the contact piece second surface 7132.

[0059] The first specific terminal contact piece 713 has an end 7134 that is located on the same plane as the end face 611 of the first wall portion 61 or on one side of the second axis A2 outside the end face 611 of the first wall portion 61 when viewed along the third axis A3. "The end 7134 of the first specific terminal contact piece 713 is located on one side of the second axis A2 outside the end face 611 of the first wall portion 61 when viewed along the third axis A3" means, for example, that the end 7134 of the first specific terminal contact piece 713 protrudes from the end face 611 of the first wall portion 61 on the second axis A2 when viewed along the third axis A3. In this embodiment, the contact piece side end face 7133 of the first specific terminal contact piece 713 is located on the same plane as the end face 611 of the first wall portion 61 or on one side of the second axis A2 outside the end face 611 of the first wall portion 61.

[0060] The first specific terminal contact piece 713 has an end 7134 that is located on the same plane as the end face 611 of the first wall portion 61 or on one side of the second axis A2 outside the end face 611 of the first wall portion 61, below the end 7122 of the terminal extension portion 7121, as viewed along the third axis A3. "The end 7134 of the first specific terminal contact piece 713 is located on one side of the second axis A2 outside the end face 611 of the first wall portion 61, below the end 7122 of the terminal extension portion 7121, as viewed along the third axis A3" means that the end 7134 of the first specific terminal contact piece 713 protrudes from the end face 611 of the first wall portion 61 on the second axis A2 at a position below the end 7122 of the terminal extension portion 7121, as viewed along the third axis A3. As shown in FIGS. 8C and 8D, the terminal extension portion 7121 and the first specific terminal contact piece 713 have portions that overlap each other when viewed along the third axis A3.

[0061] As described above, the first specific terminal contact piece 713 has the first contact piece 7136 and the second contact piece 7137 arranged along each of the pair of side surfaces 612 of the first wall portion 61. The first contact piece 7136 and the second contact piece 7137 each have an end portion 7134 of the first specific terminal contact piece 713.

[0062] As described above, the first specific terminal contact piece 713 has a contact piece first surface 7131 and a contact piece second surface 7132. The contact piece first surface 7131 is on the same plane as the side surface 612 of the first wall portion 61 or is located on one side of the third axis A3 outward from the side surface 612 of the first wall portion 61. "The contact piece first surface 7131 of the first specific terminal contact piece 713 is located on one side of the third axis A3 outward from the side surface 612 of the first wall portion 61" means, for example, that a part of the first specific terminal contact piece 713 protrudes from the side surface 612 of the first wall portion 61 on the third axis A3 when viewed along the second axis A2.

[0063] As shown in Figs. 1 and 4, the first specific terminal 71 is disposed in a first specific terminal region 722. The first specific terminal region 722 is a region surrounded by the first outer shield 81 and the first inner shield 85, and adjacent to the first connection terminal region 721. Specifically, two first specific terminals 71 are disposed in each of the two first specific terminal regions 722 (one each). The two first specific terminal regions 722 are located at both ends of the second axis A2, respectively. The first connection terminal region 721 is disposed between the two first specific terminal regions 722.

[0064] 18, the first specific terminal 71 is connected to a conductor pattern 921 of the first circuit board 92. Specifically, the first specific terminal 71 is connected to the conductor pattern 921 of the first circuit board 92 on the lower surface (surface intersecting the thickness direction) of the first specific terminal connecting piece 714.

[0065] (2.1.2.2) First connection terminal 6, the first connection terminal 72 has a contact piece 727, a spring piece 720, a rising piece 723, a falling piece 724, a connecting piece 725, and a terminal piece 726, which are integrally formed. The contact piece 727 and the rising piece 723 have contacts that come into contact with the second connection terminal 32 in the fitted state.

[0066] The contact piece 727 is plate-like with a thickness along the third axis A3, and is curved in a C-shape when viewed from the second axis A2. The outer surface of the contact piece 727 on the third axis A3 is inclined so that both sides of the second axis A2 of the contact piece 727 become gradually thinner than the central portion. In the mated state, the contact piece 727 comes into contact with the contact piece 321 of the second connection terminal 32.

[0067] The spring piece 720 is formed in a U-shape when viewed from the second axis A2. The spring piece 720 elastically deforms about the third axis A3 so that the dimension of the upper opening changes. Due to the elastic force of the spring piece 720, the contact piece 727 elastically contacts the second connection terminal 32 in the fitted state.

[0068] The rising piece 723 is a substantially rectangular plate having a thickness along the third axis A3. The lower end of the rising piece 723 is connected to the upper end of the spring piece 720. In the mated state, the rising piece 723 comes into contact with the extending piece 322 of the second connection terminal 32.

[0069] The falling piece 724 has a generally rectangular flat plate shape having a thickness along the third axis A3.

[0070] The connecting piece 725 is curved in an inverted U shape so as to connect the upper end of the rising piece 723 and the upper end of the falling piece 724 .

[0071] The terminal piece 726 is a generally rectangular flat plate having a thickness along the first axis A1. The terminal piece 726 protrudes outward from the lower end of the falling piece 724 along the third axis A3. The lower surface of the terminal piece 726 is exposed to the lower surface of the first housing 6. The first connection terminal 72 is disposed in a first connection terminal area 721 surrounded by the first outer shield 81 and the first inner shield 85. In this embodiment, the first connection terminal area 721 is an area surrounded by the first outer shield 81 and the two first inner shields 85.

[0072] 15, the first connection terminal 72 is connected to a conductor pattern 922 (a conductor pattern different from the conductor pattern 921 to which the first specific terminal 71 is connected) of the first circuit board 92. Specifically, the first connection terminal 72 is connected to the conductor pattern 922 of the first circuit board 92 at the lower surface (surface intersecting with the thickness direction) of the terminal piece 726.

[0073] (2.1.3) First Shield The first shield 8 is an electromagnetic shield for blocking electromagnetic waves. The first shield 8 reduces leakage of noise (electromagnetic waves) caused by the signal current flowing through the second terminal 3 and the first terminal 7 to the outside. Furthermore, the first shield 8 contacts the second shield 4 in the mated state. Furthermore, the first shield 8 reduces the effect of noise (electromagnetic waves) on the signal current flowing through the second terminal 3 and the first terminal 7.

[0074] 1 , the first shield 8 surrounds at least one of the multiple first terminals 7. The first shield 8 surrounds at least a first specific terminal 71 of the multiple first terminals 7. Here, the first shield 8 surrounds the multiple first specific terminals 71 and surrounds the multiple first connection terminals 72. The first shield 8 is held by the first housing 6.

[0075] The material of the first shield 8 is selected from conductive metals such as copper alloys such as phosphor bronze and Corson copper, stainless steel, and nickel silver.

[0076] As shown in FIG. 3, the first shield 8 has a first outer shield 81 and a first inner shield 85.

[0077] (2.1.3.1) First outer shield As shown in Fig. 1, the first outer shield 81 is held by the first housing 6. The first outer shield 81 surrounds the multiple first terminals 7. As shown in Figs. 15 to 18, the first outer shield 81 is connected to a ground pattern 920 of a first circuit board 92.

[0078] 3A, the first shield 8 has a pair of first horizontal shields 801 arranged side by side on a third axis A3 perpendicular to the first axis A1, and a pair of first vertical shields 802 connecting the pair of first horizontal shields 801. The pair of first horizontal shields 801 and the pair of first vertical shields 802 extend in the circumferential direction.

[0079] As shown in FIG. 1, the pair of first lateral shields 801 extend along the second axis A2. The pair of first lateral shields 801 cover the outer surfaces of the side walls of the first outer peripheral wall 64 that are aligned along the second axis A2. The first outer peripheral wall 64 has two side walls that are aligned along the second axis A2. Each of the pair of first lateral shields 801 is provided so as to straddle the two side walls that are aligned along the second axis A2. The pair of first lateral shields 801 also cover the upper surfaces of the side walls of the first outer peripheral wall 64 that are aligned along the second axis A2.

[0080] As shown in FIG. 1, the pair of first vertical shields 802 extend along the third axis A3. The pair of first vertical shields 802 cover the outer surfaces of the side walls of the first outer peripheral wall 64 that are aligned along the third axis A3. The first outer peripheral wall 64 has two side walls that are aligned along the third axis A3. Each of the pair of first vertical shields 802 is provided so as to straddle the two side walls that are aligned along the third axis A3. In addition, the pair of first vertical shields 802 cover the upper surfaces of the side walls of the first outer peripheral wall 64 that are aligned along the third axis A3.

[0081] The pair of first horizontal shields 801 and the pair of first vertical shields 802 are integrally formed to have a rectangular frame shape in a plan view. The first outer shield 81 (the pair of first horizontal shields 801 and the pair of first vertical shields 802) is plate-shaped and is formed, for example, by drawing a plate-shaped metal. The end of the first horizontal shield 801 on the second axis A2 and the end of the first vertical shield 802 on the third axis A3 are seamlessly connected. The first outer shield 81 seamlessly surrounds the first terminal 7 in the circumferential direction. A notch 83 (see FIG. 4) is formed on the inside of the corner where the first horizontal shield 801 and the first vertical shield 802 are connected.

[0082] 3A and 7, the first shield 8 has a first side wall portion 810 and a side wall extension portion 820. The side wall extension portion 820 extends in a curved manner from the first side wall portion 810. That is, the side wall extension portion 820 has a curved portion 828 curved from the first side wall portion 810. The side wall extension portion 820 extends in a curved manner from one end (upper end) of the first side wall portion 810.

[0083] 14B, the first side wall portion 810 has a pair of first lateral side walls 812, 813 arranged side by side on a third axis A3 perpendicular to the first axis A1. In this embodiment, one of the pair of first lateral side walls 812, 813 is arranged on one of the pair of first lateral shields 801, and the other of the pair of first lateral side walls 812, 813 is arranged on the other of the pair of first lateral shields 801.

[0084] The extension direction D1 of the sidewall extension 820 formed on one of the pair of first lateral sidewalls 812, 813 is a direction extending toward the other of the pair of first lateral sidewalls 812, 813. Specifically, an extension line of the extension direction D1 passing through the tip 824 of the sidewall extension 820 formed on one of the first lateral sidewalls 812 intersects with the other of the first lateral sidewalls 813 at a height equal to or higher than the center between the lower end and the upper end on the first axis A1. The extension direction D1 of the sidewall extension 820 formed on the other of the first lateral sidewalls 813 is a direction extending toward the one of the first lateral sidewalls 812. An extension line in the extending direction D1 passing through the tip 824 of the side wall extension portion 820 formed on the other first lateral side wall portion 813 intersects with the first lateral side wall portion 812 at a height equal to or higher than the midpoint between the lower end and the upper end on the first axis A1.

[0085] 14A, the extending direction D1 of the sidewall extension 820 of the first vertical shield 802 is a direction extending toward the first inner shield 85 when viewed along the third axis A3. For ease of understanding, the first housing 6 is omitted in FIG. 14A, and only the first terminal 7 and the first shield 8 are shown. Specifically, an extension line of the extending direction D1 passing through the tip 824 of the sidewall extension 820 of the first vertical shield 802 intersects with the first inner shield 85 at a height equal to or higher than the center between the lower end (first inner shield lower end 852) and the upper end (first inner shield upper end 851) of the first inner shield 85 on the first axis A1. In particular, an extension line of the extending direction D1 passing through the tip 824 of the sidewall extension portion 820 of the first vertical shield 802 intersects near the upper end on the first axis A1 with respect to the first inner shield 85 that is close to the first vertical shield 802, and intersects near the center on the first axis A1 with respect to the first inner shield 85 that is far from the first vertical shield 802. Furthermore, an extension line of the extending direction D1 passing through the tip 824 of the sidewall extension portion 820 of the first vertical shield 802 also intersects with the first vertical shield 802 on the opposite side facing this first vertical shield 802.

[0086] As shown in FIG. 7, the first side wall 810 has a first side surface 811. The first side surface 811 is a surface perpendicular to a first straight line intersecting the first axis A1. As shown in FIG. 19A and FIG. 19B, the side wall extension 820 has an extension first surface 821, an extension second surface 822, and an end surface 823. The extension first surface 821 is connected to the first side surface 811. The extension second surface 822 is on the opposite side to the extension first surface 821. The end surface 823 connects the extension first surface 821 and the extension second surface 822, and is a surface that develops so as to intersect with the extension first surface 821 and the extension second surface 822, which are the main surfaces of the plate-like side wall extension 820.

[0087] The end surface 823 of the sidewall extension 820 includes a tip surface 8230 of a tip 824 of the sidewall extension 820 in the extension direction D1. In the fitted state, the tip 824 of the sidewall extension 820 in the extension direction D1 is in contact with the second side surface 412 of the second sidewall 410, and the tip surface 8230 of the sidewall extension 820 in the extension direction D1 faces the second side surface 412 in the extension direction D1. In this manner, in the fitted state, the tip 824 of the sidewall extension 820 in the extension direction D1 is in contact with the second side surface 412 of the second sidewall 410, and the tip surface 8230 of the sidewall extension 820 in the extension direction D1 faces the second side surface 412, so that a gap is unlikely to occur between the first shield 8 of the first connector 5 and the second shield 4 of the second connector 1, and radiation noise suppression (electromagnetic shielding) is possible.

[0088] 7, the tip 824 of the side wall extension 820 is formed in a straight line along the second axis A2 that is perpendicular to the first axis A1 and the extension direction D1. This makes it difficult for a gap to occur between the side wall extension 820 and the second outer shield 41 along the second axis A2, and therefore makes it difficult for electromagnetic shielding to be impaired.

[0089] As shown in FIG. 7, the side wall extension portion 820 has an inclined surface 825 that is connected to a curved portion 828 that curves from the upper end of the first side wall portion 810 and extends obliquely downward along the extension direction D1.

[0090] 4 and 7, the sidewall extension 820 has a first sidewall extension 830 and a second sidewall extension 840 arranged side by side on a second axis A2 perpendicular to the first axis A1 and the extending direction D1. In this embodiment, the first sidewall extension 830 faces the first connection terminal area 721, and the second sidewall extension 840 faces the first specific terminal area 722. That is, in this embodiment, the sidewall extension 820 has the first sidewall extension 830 facing the first connection terminal area 721 and the second sidewall extension 840 facing the first specific terminal area 722.

[0091] 4, 19A, and 19B, the positions of the tips of the first sidewall extension 830 and the second sidewall extension 840 along the first axis A1 are different. Specifically, the sidewall extension 820 in FIG. 19B shows the first sidewall extension 830. The sidewall extension 820 in FIG. 19A shows the second sidewall extension 840. The height (position) of the tip 824 of the second sidewall extension 840 (see FIG. 19A) from the lower end of the first connector is formed to be higher than the height of the tip 824 of the first sidewall extension 830 (see FIG. 19B).

[0092] 4, the first sidewall extension 830 and the second sidewall extension 840 have different lengths along the second axis A2. Specifically, the length of the second sidewall extension 840 along the second axis A2 is longer than the length of the first sidewall extension 830.

[0093] The side wall extensions 820 are disposed on each side of the rectangular shape of the first outer shield 81 .

[0094] 4, the first shield 8 further has a holding portion 835 that is held by the first housing 6 between the first sidewall extension portion 830 and the second sidewall extension portion 840. A tip of the holding portion 835 is fixed in a groove formed in the first housing 6.

[0095] 7, the sidewall extension 820 has a pair of horizontal sidewall extensions 826 formed on the pair of first horizontal shields 801 and a vertical sidewall extension 827 formed on the first vertical shield 802. That is, in this embodiment, the sidewall extension 820 (the horizontal sidewall extension 826 or the first vertical shield 802) is provided on both the first horizontal shield 801 and the first vertical shield 802. The pair of horizontal sidewall extensions 826 and the vertical sidewall extensions 827 are respectively formed on the pair of first horizontal shields 801 and first vertical shields 802 surrounding the first specific terminal 71, thereby making it possible to improve the performance of electromagnetic shielding, particularly for the first specific terminal 71.

[0096] In the first shield 8 of the first connector 5 of this embodiment, the end surface 823 of the sidewall extension 820 includes a tip surface 8230. The tip surface 8230 of the sidewall extension 820 is, for example, a fracture surface (tip surface). The fracture surface of the sidewall extension 820 is formed, for example, by cutting a plate-shaped metal that becomes the first outer shield 81 with a die or the like. In the connector device 100, the tip 824 of the sidewall extension 820 of the first shield 8 contacts the second side surface 412 of the second sidewall 410 of the second shield 4, and the tip surface 8230 of the sidewall extension 820 faces the second side surface 412. This makes it possible to reduce the gap between the first outer shield 81 and the second outer shield 41, thereby improving the electromagnetic shielding performance. Furthermore, compared to a case where the first outer shield 81 has an inverted U-shape having a portion that curves further inwardly downward from the side wall extension 820, the width of the first outer shield 81 in the direction perpendicular to the first axis A1 can be made smaller, thereby realizing a compact size. Furthermore, when the second outer shield 41 has a recess 413 formed therein, the tip 824 of the side wall extension 820 can be inserted into the recess 413 (see FIG. 19B). This allows for a further improvement in electromagnetic shielding performance.

[0097] (2.1.3.2) First inner shield The first inner shield 85 is disposed between two of the multiple first terminals 7. Specifically, the first inner shield 85 is disposed between the first specific terminal 71 and the first connection terminal 72.

[0098] 1 and 3, in this embodiment, the first shield 8 includes two first inner shields 85. The two first inner shields 85 are arranged side by side on the second axis A2 so as to separate between one first specific terminal 71 and the multiple (six) first connection terminals 72, and between the multiple first connection terminals 72 and another one first specific terminal 71, respectively.

[0099] In this manner, by disposing the first inner shield 85 between the two first specified terminals 71, it is possible to reduce the influence of noise caused by the signal current flowing through one of the first specified terminals 71 on the signal current flowing through the other first specified terminal 71 and the first connection terminal 72. In other words, it is possible to improve the insulation (isolation) between the two first specified terminals 71.

[0100] 6, the first inner shield 85 has a main piece 854 and a pair of first inner shield extensions 853. The first inner shield extension 853 has a first inner shield upper end 851 located above, and a first inner shield lower end 852 located below the first inner shield upper end 851 in the fitted state.

[0101] The main piece 854 is a rectangular plate having a thickness along the second axis A2 and a length along the third axis A3. Each of the pair of first inner shield extensions 853 is a plate having a thickness along the second axis A2. The pair of first inner shield extensions 853 are spaced apart from each other along the third axis A3 and extend upward from the upper end surface of the main piece 854.

[0102] 1 and 4, the first inner shield 85 is fixed in the slot 69 of the first housing 6. The lower surface of the main piece 854 is exposed from the lower surface of the first housing 6, and the inner end surfaces of the pair of first inner shield extensions 853 on the third axis A3 are exposed in the recess 601.

[0103] In the first shield 8, the first inner shield 85 has a main piece 854 connected to the ground pattern 920 of the first circuit board 92. The main piece 854 is disposed below the lower end of the first outer shield 81. This facilitates the connection (e.g., soldering) of the first inner shield 85 to the ground pattern 920. The first inner shield 85 is electrically isolated from the first outer shield 81 before being connected to the first circuit board 92.

[0104] 16, the upper surface of the second inner shield 45 is connected to a ground pattern 910 of the second circuit board 91, and the lower surface of the main piece 854 of the first inner shield 85 is connected to a ground pattern 920 of the first circuit board 92. Note that the first inner shield 85 may be formed to be electrically connected to the first outer shield 81 when not connected to the first circuit board 92.

[0105] (2.2) Second Connector The second connector 1 is a header (male connector) and, as shown in Figures 9 to 12, includes a second housing 9, a plurality of (here, eight) second terminals 3, and a second shield 4. For convenience, the second connector 1 is shown upside down in Figures 9 to 12.

[0106] (2.2.1) Secondary Housing 10, the second housing 9 is made of an insulating resin material and has a flat shape that is long along the second axis A2. In the second housing 9, both sides of the third axis A3 in the center portion of the second axis A2 are cut out in a substantially rectangular shape when viewed from the first axis A1. The second housing 9 is formed in a substantially H-shape in a plan view.

[0107] 10, the second housing 9 has a second inner bottom wall 901, a second inner peripheral wall 902, a second outer bottom wall 906, and a second outer peripheral wall 905. The second inner bottom wall 901, the second inner peripheral wall 902, the second outer bottom wall 906, and the second outer peripheral wall 905 are integrally formed. At least one of the second inner bottom wall 901 and the second outer bottom wall 906 may be referred to as the second bottom wall.

[0108] The second inner bottom wall 901 is in the form of a rectangular plate that is long along the second axis A2.

[0109] The second inner peripheral wall 902 protrudes downward (upward in FIG. 10) from both ends of the third axis A3 of the second inner bottom wall 901. A region surrounded by the inner bottom surface of the second inner bottom wall 901 and the inner surface of the second inner peripheral wall 902 forms a recess 907 into which the first connector 5 fits in the mated state. Specifically, the recess 907 houses the first wall portion 61 of the first connector 5.

[0110] The second outer bottom wall 906 is composed of two partial bottom walls extending in a rectangular shape from both ends of the second inner bottom wall 901 toward the outside of the second axis A2.

[0111] The second outer peripheral wall 905 projects downward from the periphery of the second outer bottom wall 906 .

[0112] The second outer bottom wall 906 is formed with an accommodation hole 903 in which the second specific terminal 31 is disposed. The second outer bottom wall 906 is also formed with a slot 904 in which the second inner shield 45 is held.

[0113] The second housing 9 holds the plurality of second terminals 3 and the second shield 4 .

[0114] In this embodiment, the second inner peripheral wall 902 extends along the second axis A2 and has a pair of side walls facing each other along the second axis A2. Some (six) of the plurality (eight) of second terminals 3 (second connection terminals 32) are provided on the pair of side walls of the second inner peripheral wall 902. Specifically, three second connection terminals 32 are held on each of the pair of side walls of the second inner peripheral wall 902. The second connection terminals 32 are disposed in recesses provided in the second inner peripheral wall 902. The remaining second terminals 3 (second specific terminals 31) of the plurality (eight) of second terminals 3 are disposed in the receiving holes 903.

[0115] In this embodiment, the second outer shield 41 is disposed along the second outer peripheral wall 905. Also, in this embodiment, the second inner shield 45 of the second shield 4 is disposed in a groove 904 formed in the second housing 9.

[0116] (2.2.2) 2nd terminal The second terminal 3 has a terminal for transmitting signals and is formed by bending a strip-shaped metal plate. The second terminal 3 is gold-plated. The second terminal 3 is held in a second housing 9.

[0117] The second terminals 3 include one or more second specific terminals 31. The second terminals 3 also include one or more terminals (second connection terminals 32) other than the second specific terminals 31. Here, of the eight second terminals 3, two are second specific terminals 31 and the remaining six are second connection terminals 32. The two second specific terminals 31 are disposed on both sides of the second axis A2 in the second connector 1. The two second specific terminals 31 are disposed on the projection walls 990 that face the receiving hole 903 on the third axis A3, respectively.

[0118] The six second connection terminals 32 are arranged on the second axis A2 in a region between the two second specific terminals 31, separated into three on each side of the third axis A3. The six second connection terminals 32 are held by a pair of side walls of the second inner circumferential wall 902, three on each side.

[0119] The second specific terminals 31 are terminals for transmitting signals. The two second specific terminals 31 have the same shape.

[0120] The second connection terminal 32 is a terminal for transmitting a relatively low-frequency signal. Some or all of the multiple (e.g., six) second connection terminals 32 may be terminals for transmitting power. Here, the six second connection terminals 32 have the same shape. The second connection terminals 32 may include terminals having different shapes.

[0121] The second specific terminal 31 is a terminal for transmitting a signal. Specifically, a high-frequency signal having a higher frequency than the signal transmitted to the second connection terminal 32 is transmitted to the second specific terminal 31.

[0122] (2.2.2.1) Second specific terminal 13, the second specific terminal 31 has a second specific terminal connection piece 314, a second specific terminal contact piece (first contact piece) 313, and a second specific terminal linking portion (first linking portion) 312, which are integrally formed. The second specific terminal contact piece 313 has a curved second specific terminal curved portion 316. When the first specific terminal contact piece 713 of the first specific terminal 71 contacts the convex surface 3160 of the second specific terminal curved portion 316, the second specific terminal contact piece 313 elastically deforms toward one of the pair of second horizontal shields 401.

[0123] The second specific terminal linking portion (first linking portion) 312 links the second specific terminal connecting piece 314 and the second specific terminal contact piece (first contact piece) 313. The second specific terminal connecting piece 314 is disposed above the first axis A1 of the second connector 1. The second specific terminal linking portion 312 further has a second specific terminal reverse curved portion 318 that is convex in a U-shape on the side opposite to the direction in which the second specific terminal curved portion 316 is convex in a U-shape. That is, the second specific terminal curved portion 316 and the second specific terminal reverse curved portion 318 are connected to form an S-shape.

[0124] The second specific terminal 31 further includes a second specific terminal contact piece (second contact piece) 319, a second specific terminal connecting portion (second connecting portion) 3190, and a flat portion 317. The second specific terminal contact piece (second contact piece) 319 contacts the first specific terminal contact piece 713 of the first specific terminal 71. The second specific terminal contact piece 319 faces the second specific terminal contact piece 313 along the third axis A3. The second specific terminal connecting portion (second connecting portion) 3190 connects the second specific terminal connecting piece 314 and the second specific terminal contact piece (second contact piece) 319. The flat portion 317 is connected to one end of the second specific terminal contact piece 319 on the opposite side to the second specific terminal connecting portion 3190. The flat portion 317 is fixed to the second housing 9. The flat portion 317 has a surface 3170 perpendicular to the first axis A1.

[0125] Flat portion 317 and one end on the opposite side of second specific terminal contact piece 319 are connected via curved portion 315. Flat portion 317 preferably has surface 3170 formed from curved portion 315 to the tip of flat portion 317 in the extending direction. In addition, it is preferable that the length of flat portion 317 in the width direction perpendicular to the extending direction is greater than the length of curved portion 315 in the width direction.

[0126] For example, the second specific terminal 31 has a second specific terminal connecting portion 312 fixed to the second outer bottom wall 906 of the second housing 9 (see FIGS. 1 and 17).

[0127] 18, the second specific terminal 31 is connected to a conductor pattern 911 of the second circuit board 91. Specifically, the second specific terminal 31 is joined to the conductor pattern 911 of the second circuit board 91 by soldering on an upper surface (a surface intersecting the thickness direction) of the second specific terminal connection piece 314.

[0128] (2.2.2.2) Second connection terminal 11, the second connection terminal 32 has a contact piece 321, an extension piece 322, a connecting piece 323, and a terminal piece 324, which are integrally formed. The contact piece 321 and the extension piece 322 have contacts that come into contact with the first connection terminal 72 in a fitted state.

[0129] The contact piece 321 is a generally rectangular flat plate having a thickness along the third axis A3. An inner surface of the contact piece 321 on the third axis A3 is exposed to a recess 907 of the second housing 9 as shown in FIG.

[0130] The extension piece 322 is a generally rectangular flat plate having a thickness on the third axis A3. An outer surface of the extension piece 322 on the outside of the third axis A3 is exposed to the outer surface of the second housing 9, as shown in FIG.

[0131] The connecting piece 323 connects the lower end of the extension piece 322 and the lower end of the contact piece 321. The lower surface of the connecting piece 323 is exposed at the lower surface of the second inner bottom wall 901 of the second housing 9.

[0132] The terminal piece 324 is a generally rectangular flat plate having a thickness along the first axis A1. The terminal piece 324 protrudes outward along the third axis A3 from the upper end of the extension piece 322. As shown in FIG. 1, an upper surface of the terminal piece 324 is exposed on the upper surface of the second housing 9.

[0133] The second connection terminal 32 is formed integrally with the second housing 9, for example by co-molding.

[0134] 15, the second connection terminal 32 is connected to a conductor pattern 912 (a conductor pattern different from the conductor pattern 911 to which the second specific terminal 31 is connected) of the second circuit board 91. Specifically, the second connection terminal 32 is connected to the conductor pattern 912 of the second circuit board 91 on the upper surface (surface intersecting the thickness direction) of the terminal piece 324.

[0135] (2.2.3) Second Shield The second shield 4 is an electromagnetic shield for blocking electromagnetic waves. The second shield 4 reduces the leakage to the outside of noise (electromagnetic waves) caused by the signal current flowing through the second terminal 3 and the first terminal 7. In addition, the second shield 4 reduces the effect of noise (electromagnetic waves) on the signal current flowing through the second terminal 3 and the first terminal 7.

[0136] 3, the second shield 4 surrounds at least one of the multiple second terminals 3. The second shield 4 surrounds at least the second specific terminal 31 of the multiple second terminals 3. Here, the second shield 4 surrounds the multiple second specific terminals 31 and surrounds the multiple second connection terminals 32. The second shield 4 is held by the second housing 9.

[0137] The material of the second shield 4 is selected from conductive metals such as copper alloys, such as phosphor bronze and Corson copper, stainless steel, and nickel silver.

[0138] As shown in FIG. 3, the second shield 4 includes a second outer shield 41 and a second inner shield 45 .

[0139] (2.2.3.1) Second outer shield As shown in Fig. 9, the second outer shield 41 is held by a second outer wall 905 of the second housing 9. The second outer shield 41 surrounds the multiple second terminals 3. As shown in Figs. 15 to 18, the second outer shield 41 is connected to a ground pattern 910 of the second circuit board 91.

[0140] As shown in FIG. 3B, the second outer shield 41 has a pair of second horizontal shields 401 and a pair of second vertical shields 402.

[0141] The pair of second lateral shields 401 extend along the second axis A2. As shown in Fig. 9, the second lateral shields 401 cover the outer surface of the second outer peripheral wall 905. Each of the pair of second lateral shields 401 is provided straddling the second outer peripheral wall 905 and the protruding wall 990 so as to bridge the gap between the second outer peripheral wall 905 and the protruding wall 990. The second lateral shields 401 also cover at least a portion of the lower surface of the second outer peripheral wall 905.

[0142] The pair of second vertical shields 402 extend along the third axis A3. As shown in Fig. 9, the second vertical shields 402 cover the outer surface of the second outer peripheral wall 905. The second vertical shields 402 also cover at least a portion of the lower surface of the second outer peripheral wall 905.

[0143] As shown in FIG. 3B, each of the pair of second horizontal shields 401 is connected to both of the pair of second vertical shields 402. Therefore, the second outer shield 41 is formed in a rectangular frame shape in a plan view. The second outer shield 41 (the pair of second horizontal shields 401 and the pair of second vertical shields 402) is plate-shaped and is formed, for example, by drawing a plate-shaped metal. The end of the second horizontal shield 401 on the second axis A2 and the end of the second vertical shield 402 on the third axis A3 are connected without a joint (seamlessly). The second outer shield 41 seamlessly surrounds the second terminal 3 in the circumferential direction.

[0144] The second shield 4 has a second side wall portion 410. The second side wall portion 410 has a second side surface 412 that contacts the first shield 8 in the fitted state. The second side surface 412 is perpendicular to a second line that intersects with the first axis A1. As shown in FIG. 12 and FIG. 19B, the second side wall portion 410 preferably has a recess 413 on the second side surface 412. As shown in FIG. 19B, a protrusion 414 corresponding to the recess 413 is formed on the side surface of the second side wall portion 410 opposite to the second side surface 412.

[0145] The recess 413 is formed in a rectangular shape having a long side along the second axis A2 on the second side surface 412 so that the tip 824 of the first side wall extension 830 faces the recess 413 in the fitted state (see FIG. 12).

[0146] 12, 19A, and 19B, the second side wall portion 410 has a first portion 4101 that faces the first side wall extension portion 830 in the fitted state, and a second portion 4102 that faces the second side wall extension portion 840 in the fitted state. As shown in FIGS. 19A and 19B, in the fitted state, the lower end of the first portion 4101 of the second side wall portion 410 is positioned higher than the lower end of the second portion 4102 of the second side wall portion 410. This makes it easier to obtain a clicking sensation due to the recess 413 formed in the first portion 4101.

[0147] 12, the second horizontal shield 401 has a second connecting portion 422, a curved portion 421, and a holding portion 423. Each of the pair of second horizontal shields 401 has two sets of the second connecting portion 422, the curved portion 421, and the holding portion 423. The second connecting portion 422 extends from the upper end of the second side wall portion 410 toward the inside of the third axis A3. The holding portion 423 is connected to the tip of the second connecting portion 422 via the curved portion 421. The second shield 4 is fixed to the second housing 9 by inserting the holding portion 423 into a holding hole provided on the lower surface of the second housing 9.

[0148] Further, the second outer shield 41 has at its upper end a flange-shaped joint 415. The joint 415 is joined to the ground pattern 910 of the second circuit board 91.

[0149] (2.2.3.2) Second Inner Shield The second inner shield 45 is disposed between two second terminals 3 of the multiple second terminals 3. Here, the second inner shield 45 is disposed between the second specific terminal 31 and the second connection terminal 32.

[0150] 3, in this embodiment, the second shield 4 includes two second inner shields 45. The two second inner shields 45 are arranged side by side on the second axis A2 so as to separate between one second specific terminal 31 and the multiple (six) second connection terminals 32, and between the multiple second connection terminals 32 and another single second specific terminal 31, respectively.

[0151] In this manner, by disposing the second inner shield 45 between the two second specified terminals 31, it is possible to reduce the influence of noise caused by the signal current flowing through one of the second specified terminals 31 on the signal current flowing through the other second specified terminal 31 and the second connection terminal 32. In other words, it is possible to improve the insulation (isolation) between the two second specified terminals 31.

[0152] As shown in FIG. 11, the second inner shield 45 has a main piece 454 and a second inner shield extension 453. The second inner shield extension 453 has a second inner shield lower end 451 located below the first axis A1, and a second inner shield upper end 452 located above the second inner shield lower end 451. The second inner shield extension 453 has a pair of second inner extensions 4530 arranged side by side along the third axis A3. The second horizontal shield 401 and the second inner shield extension 453 are separated from each other along the third axis A3. As shown in FIG. 20A, the distance Q1 between the second horizontal shield 401 and the second inner shield extension 453 on the third axis A3 is smaller than the width Q2 of the second inner shield extension 453 along the third axis A3. Therefore, the gap between the first shield 8 of the first connector 5 and the second shield 4 of the second connector 1 is reduced, and electromagnetic shielding of the second terminal 3 can be ensured. Furthermore, since the gap Q1 is provided between the second horizontal shield 401 and the second inner shield extension portion 453, assembly is easy.

[0153] The main piece 454 has a thickness along the second axis A2 and is a rectangular plate that is long along the third axis A3. The pair of second inner shield extensions 453 are plate-shaped and extend downward from both sides of the lower end surface of the main piece 454 along the third axis A3.

[0154] 9, the second inner shield 45 is fixed to the second housing 9. The main piece 454 of the second inner shield 45 is disposed in a slot 904 formed in the second outer bottom wall 906, and the pair of second inner shield extensions 453 are housed in grooves formed in the second inner circumferential wall 902. The outer surfaces of the pair of second inner shield extensions 453 on the third axis A3 side are exposed from the second housing 9.

[0155] Here, when the second shield 4 is not connected to the ground pattern 910 of the second circuit board 91, the second outer shield 41 and the second inner shield 45 are separated from each other and are not electrically connected to each other. Note that the second inner shield 45 may be formed so as to be electrically connected to the second outer shield 41 when it is not connected to the second circuit board 91.

[0156] (2.3) Connection device As shown in FIGS. 15 to 18, the first connector 5 is connected to a first circuit board 92. The first connector 5 and the first circuit board 92 constitute a first connection device. That is, the first connection device includes the first connector 5 and the first circuit board 92 to which the first connector 5 is connected. Furthermore, the second connector 1 is connected to a second circuit board 91. The second connector 1 and the second circuit board 91 constitute a second connection device. That is, the second connection device includes the second connector 1 and the second circuit board 91 to which the second connector 1 is connected.

[0157] (2.4) Connector device The structure of a connector device 100 in which a first connector 5 and a second connector 1 are mated will be described with reference to Figures 1, 2, and 15 to 18. As shown in Figure 1, the second connector 1 is mated with the first connector 5 from above.

[0158] (2.4.1) Terminal connections In the mated state, the two first specific terminals 71 of the first connector 5 are in contact with and electrically connected to the two second specific terminals 31 of the second connector 1, respectively. This enables signals to be transmitted and received between the first circuit board 92 on which the first connector 5 is mounted and the second circuit board 91 on which the second connector 1 is mounted via the first specific terminals 71 and the second specific terminals 31. As shown in FIG. 17, in the mated state, the second specific terminal contact piece 319 of the second specific terminal 31 and the convex surface 3160 of the second specific terminal curved portion 316 come into contact with the first specific terminal contact piece 713 (the first contact piece 7136 and the second contact piece 7137) of the first specific terminal 71.

[0159] 15, in the mated state, the six first connection terminals 72 of the first connector 5 are in contact with and electrically connected to the six second connection terminals 32 of the second connector 1, respectively. This enables signals to be transmitted and received via the first connection terminals 72 and the second connection terminals 32 between the first circuit board 92 on which the first connector 5 is mounted and the second circuit board 91 on which the second connector 1 is mounted.

[0160] Specifically, the second connection terminal 32 contacts the first connection terminal 72 at an inner surface (surface intersecting with the thickness direction) of the third axis A3 of the contact piece 321 and an outer surface (surface intersecting with the thickness direction) of the third axis A3 of the extension piece 322. The first connection terminal 72 contacts the second connection terminal 32 at an outer surface (surface intersecting with the thickness direction) of the third axis A3 of the contact piece 727 and an inner surface (surface intersecting with the thickness direction) of the third axis A3 of the rising piece 723.

[0161] (2.4.2) Shield Connection In the mated state, the first outer shield 81 of the first connector 5 contacts and is electrically connected to the second outer shield 41 of the second connector 1. Also, in the mated state, the first inner shield 85 of the first connector 5 contacts and is electrically connected to the second inner shield 45 of the second connector 1. As a result, the potentials of the first shield 8 and the second shield 4 become the same ground potential.

[0162] As shown in Figs. 15 to 18, in the fitted state, the outer surface of the second outer shield 41 contacts the first outer shield 81. Here, as shown in Fig. 19B, at least a part of the tip 824 of the sidewall extension 820 in the first outer shield 81 is disposed in the recess 413 in the fitted state. Also, the tip 824 of the sidewall extension 820 contacts the recess 413 in the fitted state. In this embodiment, the tip surface 8230 of the sidewall extension 820 in the extension direction D1 contacts the recess 413. However, this is not limited thereto, and the extension first surface 821 or the extension second surface 822 of the tip 824 of the sidewall extension 820 may contact the recess 413. Also, at least a part of the tip 824 of the sidewall extension 820 contacts the inner surface of the recess 413. In the mated state, the first side wall extension 830 of the side wall extension 820 faces the recess 413. In the mated state, the side wall extension 820 faces the second side surface 412 from the outside of the second connector 1.

[0163] Furthermore, as shown in FIG. 16, the second inner shield extension 453 and the first inner shield extension 853 come into contact with each other on at least one side of the third axis A3 in the fitted state.

[0164] 18, in the mated state, the first specific terminal 71 and the first vertical shield 802 face each other on the second axis A2. In the mated state, the first specific terminal 71 and the second vertical shield 402 are electrically isolated from each other.

[0165] To mate the first connector 5 with the second connector 1, the second connector 1 is positioned above the first connector 5 as shown in Fig. 1. When the second connector 1 and the first connector 5 move relative to each other to mate with each other, the connector device 100 has a first normal posture as shown in Figs. 20A and 20B.

[0166] The operation for the second connector 1 and the first connector 5 to mate involves the second connector 1 and the first connector 5 moving relative to each other from the first normal posture along a straight line parallel to the first axis A1, transitioning to a mated state.

[0167] In the first normal position, each of the pair of second horizontal shields 401 contacts the first outer shield 81. In the first normal position, the second inner shield extension 453 contacts the first inner shield extension 853. In the first normal position, the second specific terminal 31 and the first specific terminal 71 are spaced apart from each other.

[0168] On the other hand, when the second connector 1 and the first connector 5 move relatively to be fitted together, the connector device 100 may take an inclined posture as shown in Figures 21A to 24B. Here, the inclination (θ1 in Figure 22) of the second connector 1 relative to the first connector 5 may be, for example, 5 to 20 degrees.

[0169] The inclined posture is a posture in which the first outer shield 81 is in contact with one of the pair of second horizontal shields 401 and separated from the other (see Figs. 21A to 21C), and the first inner shield extension 853 and the second inner shield extension 453 are in contact (see Figs. 22 to 24B). In this inclined posture, in the connector device 100, the second specific terminal 31 and the first specific terminal 71 are separated from each other, as shown in Figs. 23B and 24B.

[0170] That is, in the connector device 100, the first inner shield extension 853 and the second inner shield extension 453 come into contact before the first specific terminal 71 and the second specific terminal 31 come into contact. This makes it possible to suppress plastic deformation of a terminal (the terminal that is more likely to undergo plastic deformation out of the first specific terminal 71 and the second specific terminal 31, for example the second specific terminal 31) when the terminal is inserted in an inclined position, and also ensures contact reliability between the first specific terminal 71 and the second specific terminal 31.

[0171] In the connector device 100 of this embodiment, as shown in Fig. 20B, in the first normal posture, the second specific terminal curved portion 316 and the first specific terminal curved portion 716 overlap with each other on the first axis A1. This makes it possible to suppress plastic deformation of the terminal (e.g., the second specific terminal 31). Also, in the mated state, the reliability of the contact between the first specific terminal 71 and the second specific terminal 31 is improved.

[0172] In the connector device 100, one of the second connection terminal 32 and the first connection terminal 72 (the first connection terminal 72) has a curved portion 728 that elastically deforms when it comes into contact with the contact piece 321 of the other of the second connection terminal 32 and the first connection terminal 72 (the second connection terminal 32). The minimum value of the radius of curvature of the curved portion 316 of the second specific terminal is smaller than the minimum value of the radius of curvature of the curved portion 728 of the one terminal (the first connection terminal 72). This can reduce plastic deformation of the second connection terminal 32 and the first connection terminal 72, and can increase the degree of freedom in designing the second connection terminal 32 and the first connection terminal 72.

[0173] In addition, in the connector device 100, the second inner shield extension portion 453 has a pair of second inner extension portions 4530 arranged side by side along the third axis A3, as shown in FIG.

[0174] 21A shows a counterclockwise tilted position in which the first outer shield 81 is in contact with one of the pair of second horizontal shields 401 and separated from the other. On the other hand, in the tilted position, the first outer shield 81 may also be in a clockwise position (not shown) in which the first outer shield 81 is in contact with the other of the pair of second horizontal shields 401 and separated from the other.

[0175] The pair of second inner extension portions 4530 can suppress plastic deformation of the terminal (second specific terminal 31) in each of the counterclockwise and clockwise tilted positions.

[0176] (Modification of connection form) The connector device 100 may have a second normal posture when the second connector 1 and the first connector 5 move relative to each other to be fitted together. In the second normal posture, each of the pair of second horizontal shields 401 contacts the first outer shield 81. Furthermore, each of the pair of second vertical shields 402 contacts the first outer shield 81. In addition, in the second normal posture, the second inner shield extension 453 and the first inner shield extension 853 contact each other. Furthermore, in the second normal posture, the second specific terminal 31 and the first specific terminal 71 contact each other. That is, the second normal posture differs from the first normal posture described in the embodiment in whether the second specific terminal 31 and the first specific terminal 71 are in contact with each other or apart from each other.

[0177] In the modified connector device 100, when transitioning from the inclined posture to the second normal posture, the first outer shield 81 changes from a state in which it is in contact with one of the pair of second lateral shields 401 and spaced apart from the other to a state in which each of the pair of second lateral shields 401 is in contact with the first outer shield 81, and at the same time, the second specific terminal 31 and the first specific terminal 71 come into contact.

[0178] This makes it possible to suppress plastic deformation of a terminal (for example, the second specific terminal 31) when the terminal is inserted in an inclined position, and also makes it possible to ensure contact reliability between the first specific terminal 71 and the second specific terminal 31.

[0179] Note that "the second specific terminal 31 and the first specific terminal 71 come into contact at the same time that each of the pair of second horizontal shields 401 comes into contact with the first outer shield 81" does not necessarily have to happen simultaneously in the strict sense, and the second specific terminal 31 and the first specific terminal 71 may come into contact before each of the pair of second horizontal shields 401 comes into contact with the first outer shield 81 so as to prevent plastic deformation of the terminal (e.g., the second specific terminal 31).

[0180] (summary) As described above, the connector device (100) according to the first aspect includes the first connector (5) and the second connector (1). The second connector (1) is fitted to the first connector (5) from above the first axis (A1). The second connector (1) has a second housing (9), a second terminal (3), and a second shield (4). The second terminal (3) has a second specific terminal (31) and a second connection terminal (32) held in the second housing (9). The second shield (4) has a second outer shield (41) and a second inner shield (45). The second outer shield (41) surrounds the second specific terminal (31) and the second connection terminal (32) in a rectangular shape. The second inner shield (45) is disposed between the second specific terminal (31) and the second connection terminal (32). The first connector (5) has a first housing (6), a first terminal (7), and a first shield (8). The first terminal (7) is held in the first housing (6), and has a first specific terminal (71) and a first connection terminal (72) that contact the second specific terminal (31) and the second connection terminal (32), respectively, in a mated state in which the first connector (5) and the second connector (1) are mated. The first shield (8) has a first outer shield (81) and a first inner shield (85). The first outer shield (81) surrounds at least one of the first specific terminal (71) and the first connection terminal (72).
