[0017] 1 and 2, a connection device 10 according to an embodiment of the present invention includes an assembly 11 and a mating assembly 61. The assembly 11 and the mating assembly 61 are connectable to each other along the vertical direction. The vertical direction in this embodiment is the Z direction. Up is the +Z direction, and down is the -Z direction. The assembly 11 and the mating assembly 61 are incorporated, for example, inside an electronic device (not shown). However, the present invention is not limited to this and can be applied to various connection devices 10.

[0018] The mating assembly 61 of this embodiment will now be described.

[0019] 1, 6, and 7, the mating assembly 61 of this embodiment includes a mating board 66 and a mating connector 62. The mating connector 62 is mounted on and fixed to the mating board 66. However, the present invention is not limited to this. For example, the mating assembly 61 may further include other members in addition to the above-mentioned members.

[0020] 6 and 7, the mating connector 62 of this embodiment includes a mating holding member 70 made of an insulator and 20 (i.e., two or more) mating terminals 80 made of a conductor. The mating connector 62 is formed with a mating receiving portion 64. The mating receiving portion 64 is a space recessed upward and open downward. However, the present invention is not limited to this. For example, the mating connector 62 may include only one mating terminal 80. On the other hand, the mating connector 62 may further include other members in addition to the above-mentioned members.

[0021] The mating holding member 70 of this embodiment has a base 72 and a peripheral wall 74. The base 72 is located at the upper end of the mating holding member 70 in the up-down direction. The peripheral wall 74 extends downward from the base 72 and surrounds the mating receiving portion 64 in a horizontal plane (XY plane) perpendicular to the up-down direction. The peripheral wall 74 has two side walls 75 and two connecting walls 76. The two side walls 75 extend parallel to each other along a pitch direction perpendicular to the up-down direction. The pitch direction in this embodiment is the X direction. The two connecting walls 76 extend parallel to each other along a width direction perpendicular to both the up-down direction and the pitch direction. The width direction in this embodiment is the Y direction. Each connecting wall 76 connects the two side walls 75 to each other in the width direction.

[0022] The mating holding member 70 of this embodiment is a single member having the above-described structure. However, the present invention is not limited to this. For example, the mating holding member 70 may be formed by combining multiple members.

[0023] 7, the mating terminal 80 of this embodiment includes ten (i.e., two or more) first terminals 80F and ten (i.e., two or more) second terminals 80S. That is, the mating terminal 80 includes two types of mating terminals 80. The first terminals 80F and the second terminals 80S have slightly different shapes but have the same structure.

[0024] 8 and 9, each of the mating terminals 80 of this embodiment is a single metal plate having a bend. Each of the mating terminals 80 has a mating fixed portion 82 and a mating contact portion 84. Each of the mating fixed portions 82 is located at the upper end of the mating terminal 80 and extends along the width direction. Each of the mating contact portions 84 extends downward from the mating fixed portion 82. Each of the mating contact portions 84 has a U-shape in an orthogonal plane (YZ plane) perpendicular to the pitch direction. Both sides of this U-shape in the width direction function as two contact surfaces 86 that electrically connect with the connector 12 (see FIG. 1).

[0025] Each of the mating terminals 80 in this embodiment has the structure described above. However, the present invention is not limited to this. For example, the first terminals 80F and the second terminals 80S may have the same shape. That is, the mating terminals 80 may include only one type of mating terminal 80. On the other hand, the mating terminals 80 may include three or more types of mating terminals 80. Furthermore, the structure of each of the mating terminals 80 is not particularly limited. For example, each of the mating contact portions 84 may have only one contact surface 86.

[0026] Referring to FIG. 7, the mating terminals 80 of this embodiment are divided into two rows in the width direction. In other words, the mating connector 62 has two mating terminal rows. In each mating terminal row, five first terminals 80F and five second terminals 80S are arranged alternately along the pitch direction. The first terminals 80F and second terminals 80S in the two mating terminal rows are arranged with 180-degree rotational symmetry around an axis parallel to the up-down direction. The first terminals 80F in one of the mating terminal rows are Counterpart terminal row The mating terminals 80 are arranged side by side with the other second terminals 80S in the width direction. The mating terminals 80 of the present embodiment are arranged as described above. However, the arrangement of the mating terminals 80 in the present invention is not particularly limited.

[0027] The two mating terminal rows are attached to the two side walls 75, respectively. More specifically, each of the mating contact portions 84 in this embodiment is insert-molded into the side wall 75, and is thereby held by the mating holding member 70. Referring to FIGS. 8 and 9 , one of the two contact surfaces 86 of each of the mating contact portions 84 is exposed to the outside in the width direction of the side wall 75, and the other of the two contact surfaces 86 is exposed inside the mating receiving portion 64. However, the present invention is not limited to this. For example, each of the mating contact portions 84 may be press-fitted into the side wall 75.

[0028] Referring to FIG. 7 , the mating fixed portions 82 of the mating terminals 80 are divided into four rows in the width direction. Two of the four rows include only the mating fixed portions 82 of the first terminals 80F, and the other two of the four rows include only the mating fixed portions 82 of the second terminals 80S. When the mating connector 62 is viewed in the up-down direction, the two rows of the mating fixed portions 82 of the first terminals 80F are located inside the peripheral wall 74, and the two rows of the mating fixed portions 82 of the second terminals 80S are located outside the peripheral wall 74 in the width direction. In each of the four rows, five (i.e., two or more) mating fixed portions 82 are arranged in the pitch direction. The mating fixed portions 82 of this embodiment are arranged as described above. However, the arrangement of the mating fixed portions 82 in the present invention is not particularly limited.

[0029] Referring to Figure 10, the underside of the mating substrate 66 of this embodiment is provided with 20 (i.e., two or more) mating conductive pads 68 made of a conductor and a mating resist 69 made of an insulator.

[0030] The mating conductive pads 68 are provided to correspond to the mating fixed portions 82 of the mating terminals 80, respectively. More specifically, the mating conductive pads 68 are divided into four mating pad rows 67 in the width direction. In each mating pad row 67, five (i.e., two or more) mating conductive pads 68 are lined up along the pitch direction. When the mating connector 62 (see FIG. 7 ) is mounted on the mating board 66, the four rows of mating fixed portions 82 are fixed and connected to the mating conductive pads 68 of the four mating pad rows 67, respectively, by soldering. As a result, the mating connector 62 is fixed to the mating board 66 and electrically connected to the mating board 66.

[0031] The mating resist 69 surrounds the mating conductive pad 68 in the XY plane, and prevents short-circuiting of the mating fixed portion 82 during soldering.

[0032] The mating substrate 66 in this embodiment is a rigid circuit board having rigidity and has the structure described above. However, the present invention is not limited to this. For example, the mating substrate 66 may be a flexible FPC (Flexible Printed Circuits), which is easily flexible. In this case, the mating substrate 66 may be reinforced with a reinforcing plate (not shown).

[0033] The assembly 11 (see FIG. 1) of this embodiment will be described below.

[0034] Referring to FIG. 1 , the assembly 11 of this embodiment includes a substrate 50, a connector 12, and a fixing mechanism 40. The connector 12 can be mounted on the substrate 50. More specifically, the substrate 50 has a main surface 52. The connector 12 can be mounted on the main surface 52. The connector 12 can also be fixed to the main surface 52 by the fixing mechanism 40. The assembly 11 of this embodiment includes only the above-mentioned components. However, the present invention is not limited to this. For example, the assembly 11 may further include other components in addition to the above-mentioned components.

[0035] 1 and 2, the main surface 52 of this embodiment is the upper surface of the substrate 50 and is a plane extending parallel to the XY plane. The connector 12 of this embodiment can be mated with a mating connector 62 including mating terminals 80 in a vertical direction perpendicular to the main surface 52. However, the present invention is not limited to this. For example, the main surface 52 may be a plane obliquely intersecting the XY plane. That is, it is sufficient that the connector 12 can be mated with a mating connector 62 including mating terminals 80 in a vertical direction intersecting the substrate 50 (specifically, the main surface 52).

[0036] As described above, the connector 12 and the mating connector 62 of this embodiment are so-called on-board connectors. Furthermore, the connector 12 is a receptacle, and the mating connector 62 is a plug. However, the present invention is not limited to this and can be applied to various connectors.

[0037] 1, 14, and 15, the connector 12 of this embodiment includes a holding member 20 made of an insulator, ten (i.e., two or more) terminals 30 made of a conductor, and ten (i.e., two or more) additional terminals (fixing mechanisms) 40 made of a conductor. The connector 12 is formed with a receiving portion 14. The receiving portion 14 is a space recessed downward and open upward. However, the present invention is not limited to this. For example, the connector 12 may include only one terminal 30. The additional terminal 40 may be provided as needed. Meanwhile, the connector 12 may further include other members in addition to the above-mentioned members.

[0038] 14 and 15, the holding member 20 of this embodiment has a bottom portion 22, an outer periphery 24, and an island-shaped portion 28. The bottom portion 22 is located at the lower end of the holding member 20. The outer periphery 24 extends upward from the bottom portion 22 and surrounds the receiving portion 14 in the XY plane. The island-shaped portion 28 is located in the middle of the receiving portion 14 in the XY plane. The island-shaped portion 28 protrudes upward from the bottom portion 22 and extends along the pitch direction. The outer periphery 24 has two side portions 25 and two end walls 26. The two side portions 25 extend parallel to each other along the pitch direction. The two end walls 26 extend parallel to each other along the width direction. Each end wall 26 connects the two side portions 25 to each other in the width direction.

[0039] The holding member 20 of this embodiment is a single member having the above-described structure. However, the present invention is not limited to this. For example, the holding member 20 may be formed by combining multiple members.

[0040] Referring to Fig. 15, the terminals 30 of this embodiment have the same shape. Each of the terminals 30 is a single metal plate having a bend. However, the present invention is not limited to this. For example, the terminals 30 may have different shapes. Each of the terminals 30 may be formed by joining multiple members.

[0041] The structure of one of the terminals 30 of this embodiment will be described below. The following description is applicable to each of the terminals 30.

[0042] Referring to Figure 16, the terminal 30 of this embodiment has a lower end portion 31, a held portion 32, a connecting portion 33, an auxiliary contact 34, a first support portion 35, a main contact 36, a second support portion 37, and a pressed portion 38.

[0043] The lower end 31 is located at the lower end of the terminal 30 and extends along the width direction. The held portion 32 extends upward from the end of the lower end 31 in the width direction. The held portion 32 is formed with two press-fit protrusions 322 (see FIG. 15 ) that protrude on both sides in the pitch direction. The connecting portion 33 extends from the upper end of the held portion 32 along the width direction, away from the lower end 31. The auxiliary contact 34 is provided at the end of the connecting portion 33 in the width direction. In other words, the connecting portion 33 connects the held portion 32 and the auxiliary contact 34 to each other in the width direction. The auxiliary contact 34 protrudes away from the lower end 31 in the width direction.

[0044] The first support portion 35 extends from the auxiliary contact 34 so as to move away from the lower end portion 31 in the width direction. The main contact 36 is provided at an end of the first support portion 35 in the width direction. The first support portion 35 is elastically deformable. The main contact 36 is supported by the first support portion 35 and can move mainly within the YZ plane as the first support portion 35 elastically deforms. The first support portion 35 of this embodiment has a U-shape and is easily elastically deformable.

[0045] Specifically, the first support portion 35 has an outer arm portion 352, a bottom arm portion 358, and an inner arm portion 354. The bottom arm portion 358 is located at the lower end of the first support portion 35 and extends along the width direction. The outer arm portion 352 extends downward from the auxiliary contact 34 to one end of the bottom arm portion 358 in the width direction. The inner arm portion 354 extends upward from the other end of the bottom arm portion 358 in the width direction to the main contact 36. The main contact 36 is located at the upper end of the inner arm portion 354 and protrudes toward the auxiliary contact 34 in the width direction. In other words, the auxiliary contact 34 faces the main contact 36 in the width direction.

[0046] The first support portion 35 of this embodiment has a long spring length and a flexible structure. The main contact 36 of this embodiment is movable in the vertical and horizontal directions. However, the present invention is not limited to this. The structure of the first support portion 35 can be modified as needed. The main contact 36 only needs to be movable in the horizontal direction. For example, the outer arm portion 352, the bottom arm portion 358, and the inner arm portion 354 may each have an arc shape in the YZ plane. In this case, the outer arm portion 352, the bottom arm portion 358, and the inner arm portion 354 may be smoothly connected in the YZ plane to form a single arc.

[0047] The second support portion 37 extends from the main contact 36 so as to move away from the auxiliary contact 34 in the width direction. The pressed portion 38 is provided at an end of the second support portion 37 in the width direction. The second support portion 37 is elastically deformable. The pressed portion 38 is supported by the second support portion 37 and can move mainly within the YZ plane as the second support portion 37 elastically deforms. The second support portion 37 in this embodiment has an L-shape and is easily elastically deformable.

[0048] More specifically, the second support portion 37 in this embodiment has an upper end portion 371, a vertical arm portion 372, and a horizontal arm portion 374. The upper end portion 371 extends from the main contact 36 in the width direction, away from the auxiliary contact 34. The vertical arm portion 372 extends downward from the end of the upper end portion 371 in the width direction. The horizontal arm portion 374 extends from the lower end of the vertical arm portion 372 in the width direction, away from the main contact 36. The pressed portion 38 is provided on the horizontal arm portion 374 and protrudes downward. The lower end of the pressed portion 38 is located at the same position as the lower end of the lower end portion 31 in the up-down direction.

[0049] In the present embodiment, the vertical dimension HV of the vertical arm portion 372 is larger than the width dimension WV. In the present embodiment, the width dimension WH of the horizontal arm portion 374 is larger than the vertical dimension HH. By forming the vertical arm portion 372 and the horizontal arm portion 374 as described above, the spring length of the second support portion 37 can be increased without increasing the widthwise distance between the main contact 36 and the pressed portion 38. As a result, the widthwise dimension of the terminal 30 can be reduced while improving the spring properties of the second support portion 37.

[0050] The second support portion 37 of this embodiment has a long spring length and has a flexible structure. The pressed portion 38 of this embodiment is movable in the vertical and width directions. However, the present invention is not limited to this, and the structure of the second support portion 37 can be modified as necessary. For example, the second support portion 37 may have only the vertical arm portion 372. In this case, the pressed portion 38 may be provided at the lower end of the vertical arm portion 372.

[0051] Each of the terminals 30 in this embodiment has the structure described above. The auxiliary contact 34 and the main contact 36 in each of the terminals 30 are portions that electrically connect with the mating connector 62 (see FIG. 1 ). However, the present invention is not limited to this. As long as each of the terminals 30 has an elastically deformable first support portion 35, a main contact 36 supported by the first support portion 35, an elastically deformable second support portion 37, and a pressed portion 38 supported by the second support portion 37, the structure of each of the terminals 30 can be modified as needed. For example, the auxiliary contact 34 may be provided as needed.

[0052] Referring to FIG. 15, the additional terminals 40 of this embodiment have the same shape. Each of the additional terminals 40 is a single metal plate having a bend. However, the present invention is not limited to this. For example, the additional terminals 40 may have different shapes. Each of the additional terminals 40 may be formed by joining multiple members.

[0053] The structure of one of the additional terminals 40 of this embodiment will be described below. The following description is applicable to each of the additional terminals 40.

[0054] Referring to Figure 17, the additional terminal 40 of this embodiment has a fixed portion 41, a held portion 42, a connecting portion 43, an auxiliary contact 44, a first support portion 45, a main contact 46, and an upper end portion 471.

[0055] The fixed portion 41 is located at the lower end of the additional terminal 40 and extends along the width direction. The held portion 42 extends upward from the end of the fixed portion 41 in the width direction. The held portion 42 has two press-fit protrusions 422 (see Figure 15) that protrude from both sides in the pitch direction. The connecting portion 43 extends from the upper end of the held portion 42 along the width direction, away from the fixed portion 41. The auxiliary contact 44 is provided at the end of the connecting portion 43 in the width direction. In other words, the connecting portion 43 connects the held portion 42 and the auxiliary contact 44 to each other in the width direction. The auxiliary contact 44 protrudes in the width direction, away from the fixed portion 41.

[0056] The first support portion 45 extends from the auxiliary contact 44 in the width direction so as to move away from the fixed portion 41. The main contact 46 is provided at an end of the first support portion 45 in the width direction. The upper end portion 471 extends from the main contact 46 along the width direction so as to move away from the auxiliary contact 44. The first support portion 45 is elastically deformable. The main contact 46 is supported by the first support portion 45 and can move mainly within the YZ plane as the first support portion 45 elastically deforms. The first support portion 45 of the present embodiment has a U-shape and is easily elastically deformable.

[0057] Specifically, the first support portion 45 has an outer arm portion 452, a bottom arm portion 458, and an inner arm portion 454. The bottom arm portion 458 is located at the lower end of the first support portion 45 and extends along the width direction. The outer arm portion 452 extends downward from the auxiliary contact 44 to one end of the bottom arm portion 458 in the width direction. The inner arm portion 454 extends upward from the other end of the bottom arm portion 458 in the width direction to the main contact 46. The main contact 46 is located at the upper end of the inner arm portion 454 and protrudes toward the auxiliary contact 44 in the width direction. In other words, the auxiliary contact 44 faces the main contact 46 in the width direction.

[0058] The first support portion 45 of this embodiment has a long spring length and has a structure that is easily flexible. The main contact 46 of this embodiment is movable in the vertical and width directions. However, the present invention is not limited to this. For example, the first support portion 45 may have a structure that is relatively difficult to flex.

[0059] Comparing FIG. 17 with FIG. 16, the additional terminal 40 of this embodiment has a similar shape to the terminal 30, except that it has an upper end 471 instead of the second support portion 37. However, the thickness TC of the first support portion 35 of the terminal 30 is thinner than the thickness TA of the first support portion 45 of the additional terminal 40. In other words, the first support portion 35 is more flexible than the first support portion 45. However, the present invention is not limited to this. For example, the additional terminal 40 may have the same shape as the terminal 30, except that it has an upper end 471 instead of the second support portion 37.

[0060] Referring to Figure 17, the additional terminal 40 of this embodiment has the above-mentioned structure. The auxiliary contact 44 and the main contact 46 of each additional terminal 40 are portions that electrically connect with the mating connector 62 (see Figure 1). However, the present invention is not limited to this. For example, the auxiliary contact 44 may be provided as needed. Also, as described above, the additional terminal 40 may be provided as needed.

[0061] The arrangement of the terminals 30 and the additional terminals 40 in this embodiment will be described below.

[0062] 14 and 15 , the terminals 30 and additional terminals 40 of this embodiment are divided into two terminal rows 16 in the width direction. In other words, the connector 12 has two terminal rows 16. In each terminal row 16, five terminals 30 and five additional terminals 40 are alternately arranged along the pitch direction. However, the present invention is not limited to this. For example, the connector 12 may have only one terminal row 16, or may have three or more terminal rows 16. Furthermore, each terminal row 16 may include one terminal 30 and one additional terminal 40. That is, in each terminal row 16, one or more terminals 30 and one or more additional terminals 40 may be alternately arranged along the pitch direction.

[0063] 11, the terminals 30 and additional terminals 40 in the two terminal rows 16 of this embodiment are arranged with 180-degree rotational symmetry about an axis parallel to the vertical direction (an axis passing through the center point 18 depicted in FIG. 18 and extending in the vertical direction). The terminals 30 in one of the terminal rows 16 are aligned in the width direction with the additional terminals 40 in the other terminal row 16. Referring to FIG. 3, the terminals 30 are arranged in positions corresponding to the first terminals 80F of the mating connector 62 in the XY plane. The additional terminals 40 are arranged in positions corresponding to the second terminals 80S of the mating connector 62 in the XY plane.

[0064] The terminals 30 and additional terminals 40 in this embodiment are arranged as described above. However, the arrangement of the terminals 30 and additional terminals 40 in the present invention is not particularly limited. For example, the connector 12 and the mating connector 62 may each include only one terminal 30 and one first terminal 80F arranged at positions corresponding to each other on the XY plane.

[0065] 14 and 15, the two terminal rows 16 of this embodiment are attached to the two side portions 25, respectively, as will be described below.

[0066] In this embodiment, ten retaining grooves 252 are formed in each side portion 25. That is, two rows of retaining grooves 252 are formed in the retaining member 20. The retaining grooves 252 in each row are aligned in the pitch direction. In each row, five of the retaining grooves 252 are portions that respectively hold terminals 30, and the other five of the retaining grooves 252 are portions that respectively hold additional terminals 40. Each of the retaining grooves 252 penetrates the side portion 25 in the vertical direction and opens downward.

[0067] The holding member 20 of this embodiment has ten terminal receiving portions 29 formed therein. The terminal receiving portions 29 are aligned in the pitch direction. Each of the terminal receiving portions 29 penetrates the bottom portion 22 in the vertical direction and opens downward. Each of the terminal receiving portions 29 extends between the two holding grooves 252 in the width direction. Each of the terminal receiving portions 29 is partially located inside the island-shaped portion 28 and partially located below the receiving portion 14.

[0068] Each of the terminals 30 and the additional terminals 40 is inserted into the terminal receiving portion 29 from below. Each of the terminals 30 is partially received in the terminal receiving portion 29 so as to be aligned with one of the additional terminals 40 in the width direction. In other words, each of the terminal receiving portions 29 receives one terminal 30 and one additional terminal 40. The retained portion 32 of each of the terminals 30 is press-fitted and held in the corresponding retaining groove 252. Similarly, the retained portion 42 of each of the additional terminals 40 is press-fitted and held in the corresponding retaining groove 252. In other words, the retaining member 20 holds the terminals 30 and the additional terminals 40.

[0069] In this embodiment, the island-shaped portion 28 is provided with ten intermediate walls 284 corresponding to the respective terminal receiving portions 29. The intermediate walls 284 are aligned in the pitch direction. With reference to FIGS. 12 and 13 , each intermediate wall 284 is located at the middle of the corresponding terminal receiving portion 29 in the width direction. In each terminal receiving portion 29, the terminal 30 and the additional terminal 40 are located on both sides of the intermediate wall 284 in the width direction. However, in each terminal receiving portion 29, the pressed portion 38 of the terminal 30 is located below the intermediate wall 284.

[0070] Referring to FIG. 15 , as described above, in this embodiment, the terminal 30 and the additional terminal 40 are each press-fit into the holding member 20 from below and held therein. When the terminal 30 and the additional terminal 40 are held in the holding member 20, the bottom arm portion 358 of the terminal 30 and the bottom arm portion 458 of the additional terminal 40 are exposed downward. However, the present invention is not limited to this. For example, the terminal 30 and the additional terminal 40 may each be held in the holding member 20 by insert molding. In this case, the holding groove 252 does not need to be provided. Furthermore, the terminal receiving portion 29 does not need to open downward. The intermediate wall 284 may be provided as needed.

[0071] 12 together with FIG. 8, when terminal 30 and additional terminal 40 are held by holding member 20, distance DT in the width direction between each auxiliary contact 34 and main contact 36 of terminal 30 is smaller than size TT in the width direction of mating contact portion 84 of first terminal 80F of mating connector 62. Distance DT in the width direction between each auxiliary contact 44 and main contact 46 of additional terminal 40 is smaller than size TT in the width direction of mating contact portion 84 of second terminal 80S of mating connector 62.

[0072] 18 together with FIG. 11, when the terminals 30 are held by the holding member 20, the pressed portions 38 of all the terminals 30 are located close to each other in the width direction. That is, the pressed portions 38 are aligned substantially in a single row in the pitch direction. When the additional terminals 40 are held by the holding member 20, the fixed portions 41 of the additional terminals 40 are divided into two rows in the width direction. The fixed portions 41 in each row are aligned in the pitch direction.

[0073] 18, 20 (i.e., two or more) conductive pads 58 made of a conductor and resist 59 made of an insulator are provided on a main surface 52 of a substrate 50 of this embodiment. The substrate 50 has one intermediate pad row 54 and two side pad rows 56 corresponding to the terminal rows 16, respectively. In the intermediate pad row 54, ten (i.e., two or more) conductive pads 58 are lined up along the pitch direction. In each of the side pad rows 56, five (i.e., one or more) conductive pads 58 are lined up along the pitch direction. The intermediate pad row 54 is located between the two side pad rows 56 in the width direction.

[0074] When the connector 12 (see FIG. 11) is mounted on the main surface 52, the additional terminals 40 in each of the terminal rows 16 are fixed to the conductive pads 58 in the corresponding side pad rows 56. In this embodiment, the fixed portions 41 of the additional terminals 40 are fixed and connected to the conductive pads 58 by soldering. As a result, the connector 12 is fixed to the substrate 50. Resist 59 surrounds the conductive pads 58 in the XY plane, preventing short-circuiting of the fixed portions 41 during soldering.

[0075] The substrate 50 of this embodiment is a rigid circuit board having rigidity and has the structure described above. However, the present invention is not limited to this. For example, the substrate 50 may be an FPC that is flexible. In this case, the substrate 50 may be reinforced with a reinforcing plate (not shown).

[0076] 14, according to this embodiment, when the terminals 30 and the additional terminals 40 are held by the holding member 20, the lower ends of the lower end portions 31 of the terminals 30 and the lower end of the pressed portions 38 are at the same position in the up-down direction as the lower ends of the fixed portions 41 of the additional terminals 40. Referring to FIGS. 12 and 13 in conjunction with FIG. 18, according to this arrangement, when the additional terminals 40 are fixed to the board 50, the lower end portions 31 of the terminals 30 come into contact with the resist 59 of the board 50, and the pressed portions 38 come into contact with the conductive pads 58 of the intermediate pad row 54, without any portion of the terminals 30 being fixed to the board 50. As a result, the connector 12 is electrically connected to the board 50.

[0077] Referring to Figure 11, according to this embodiment, when the connector 12 is mounted on the main surface 52, the additional terminals 40 are fixed on the main surface 52, thereby functioning as a fixing mechanism 40 for fixing the connector 12 to the substrate 50.

[0078] According to this embodiment, the fixed portions 41 of the additional terminals 40 are located on both sides of the holding member 20 in the width direction and are equally spaced apart between both sides of the holding member 20 in the pitch direction. This arrangement allows the connector 12 to be firmly fixed to the board 50. However, the present invention is not limited to this. For example, if the connector 12 is small in size, the connector 12 may include only one additional terminal 40. Furthermore, the connector 12 may include a hold-down that functions as the fixing mechanism 40 instead of or in addition to the additional terminal 40. Furthermore, the fixing mechanism 40 does not have to be a member held by the holding member 20. For example, the connector 12 may be fixed to the board 50 by the fixing mechanism 40, such as a screw.

[0079] 12 , the pressed portion 38 of the terminal 30 in this embodiment is arranged so as to come into contact with the conductive pad 58 without being pressed against it when the connector 12 is fixed to the substrate 50. This embodiment is preferable from the viewpoint of easily soldering the fixed portion 41 to the conductive pad 58 and bringing the pressed portion 38 into contact with the conductive pad 58. However, the present invention is not limited to this. For example, if the fixing mechanism 40 is a screw, the pressed portion 38 may be pressed against the conductive pad 58 when the connector 12 is fixed to the substrate 50.

[0080] The mating operation when mating the connector 12 with the mating connector 62 (see FIG. 1) will be described below.

[0081] 1 and 2, the connector 12 of this embodiment can be mated with a mating connector 62 in the vertical direction while fixed to a substrate 50. However, the present invention is not limited to this. For example, if the connector 12 does not include additional terminals 40, the connector 12 may be fixed to the substrate 50 after mating with the mating connector 62. In this case, for example, the substrate 50 and the mating substrate 66 may be fixed to each other with screws. That is, the connector 12 of this embodiment can be fixed to the substrate 50 by various fixing mechanisms 40, such as additional terminals 40, screws, and hold-downs.

[0082] 3, 7, and 11, when connector 12 is mated with mating connector 62, island-like portion 28 of connector 12 is received in mating receiving portion 64 of mating connector 62, and peripheral wall 74 of mating connector 62 is received in receiving portion 14 of connector 12. Referring to FIGS. 4 and 5, at this time, each mating contact portion 84 of first terminal 80F is received between auxiliary contact 34 and main contact 36 while pressing widthwise and downward against main contact 36 and auxiliary contact 34 of terminal 30. Similarly, each mating contact portion 84 of second terminal 80S is received between auxiliary contact 44 and main contact 46 while pressing widthwise and downward against main contact 46 and auxiliary contact 44 of additional terminal 40.

[0083] The auxiliary contact 44 of the additional terminal 40 is close to the held portion 42 fixed to the holding member 20, and therefore moves very little even when pressure is applied. On the other hand, the main contact 46 is supported by the highly springy first support portion 45, and therefore moves inward and downward in the width direction. As a result, the bottom arm portion 458 of the first support portion 45 is pressed against the main surface 52 of the substrate 50.

[0084] Similarly, the auxiliary contact 34 of the terminal 30 is close to the held portion 32 fixed to the holding member 20, and therefore moves very little even when pressure is applied. On the other hand, the main contact 36, which is supported by the inner arm portion 354 of the first support portion 35, which has high springiness, receives forces inward and downward in the width direction, similar to the main contact 46, and moves in a rotating manner. As a result, the pressed portion 38 is pressed against the conductive pad 58, and the main contact 36 moves substantially only inward in the width direction.

[0085] As described above, when the connector 12 is mated with the mating connector 62, the main contacts 36 of the terminals 30 come into contact with the mating terminals 80 and move in the width direction. At this time, the second support portions 37 of the terminals 30 elastically deform, causing each of the pressed portions 38 to move inward in the width direction while being pressed against the conductive pads 58. In other words, when the connector 12 is in a mated state with the mating connector 62, the pressed portions 38 are pressed against the conductive pads 58 in the up-down direction. Therefore, if the board 50 is removed in the mated state, each of the pressed portions 38 will move below the location where the conductive pads 58 were located.

[0086] 18 together with FIG. 11, according to this embodiment, when the connector 12 is in a mated state, the pressed portions 38 of the terminals 30 in the two terminal rows 16 are pressed in the up and down directions against the conductive pads 58 in the intermediate pad row 54. That is, the terminals 30 in this embodiment are connected to the conductive pads 58 simply by being pressed against the conductive pads 58, rather than by soldering. This connection method allows two adjacent conductive pads 58 to be positioned extremely close to each other, thereby enabling the terminals 30 to be spaced at a narrower pitch.

[0087] According to this embodiment, it is possible to provide an assembly 11 including a connector 12 mounted on a substrate 50, and having a structure suitable for narrowing the pitch of the terminals 30. By narrowing the pitch of the terminals 30, it is possible to reduce the size of the connector 12 in the pitch direction. In addition, since the step of soldering the terminals 30 is not required, the manufacturing cost of the assembly 11 can be reduced.

[0088] 11, the terminals 30 and the additional terminals 40 of this embodiment are arranged alternately in the pitch direction, so that the pressed portions 38 of the terminals 30 can be reliably pressed against the conductive pads 58. However, the present invention is not limited to this. do not have The arrangement of the terminals 30 and the additional terminals 40 in the pitch direction can be changed as required.

[0089] 11 and 18 with FIGS. 7 and 10, the mating conductive pads 68 of the mating assembly 61 are arranged in four rows to prevent short circuits during soldering, which increases the width of the mating connector 62. On the other hand, according to this embodiment, the pitch of the pressed portions 38 can be made extremely short, so the conductive pads 58 that come into contact with the pressed portions 38 can be arranged in a single row along the pitch direction. This makes it possible to reduce not only the size of the connector 12 in the pitch direction but also the size in the width direction. In other words, according to this embodiment, the area occupied by the connector 12 on the main surface 52 of the board 50 can be reduced.

[0090] 4 and 5, according to this embodiment, when the connector 12 is in a mated state, the main contacts 36 and the auxiliary contacts 34 sandwich the mating terminal 80 in the width direction and contact the mating terminal 80. That is, the terminal 30 contacts the mating terminal 80 at two points. With this structure, even if the mating connector 62 is misaligned in the width direction, the terminal 30 will stably contact the mating terminal 80 with the designed contact force. Furthermore, because the pressed portion 38 is not fixed but can move in the width direction, an even more stable contact force can be obtained. Similarly, the additional terminal 40 also stably contacts the mating terminal 80 at two points.

[0091] In this embodiment, the main contacts 36 are pressed in the width direction by the mating contact portions 84 sandwiched between the main contacts 36 and the auxiliary contacts 34. However, the present invention is not limited to this. For example, if the terminals 30 do not have auxiliary contacts 34, the distance between the mating contact portions 84 of the first terminals 80F and the second terminals 80S, which are aligned in the width direction, may be shorter than the distance between the main contacts 36 of the terminals 30 and the main contacts 46 of the additional terminals 40, which are aligned in the width direction. Furthermore, the mating contact portions 84 may be sandwiched between the main contacts 36 and a portion of the holding member 20. Similar modifications are possible even when the additional terminals 40 do not have auxiliary contacts 44.

[0092] According to this embodiment, the spring of the horizontal arm portion 374 located at the lower end of the second support portion 37 can make the contact force between the pressed portion 38 and the conductive pad 58 equal to or greater than a predetermined value without affecting the contact force of the main contact 36, and can also reduce variation in the contact force between the pressed portion 38 and the conductive pad 58. However, the present invention is not limited to this. For example, the horizontal arm portion 374 does not have to be located at the lower end of the second support portion 37, and may be located between the main contact 36 and the pressed portion 38. Furthermore, the horizontal arm portion 374 may be located as needed.

[0093] 15, each terminal receiving portion 29 is provided with two restriction walls 286. That is, the holding member 20 of this embodiment has the restriction walls 286. Each of the restriction walls 286 of this embodiment is an inner wall surface of the terminal receiving portion 29, and is a plane extending parallel to the YZ plane. The two restriction walls 286 in each terminal receiving portion 29 sandwich the terminal 30 and the additional terminal 40 in the pitch direction.

[0094] 12 and 13 , each of the restriction walls 286 extends between the two side portions 25 in the width direction. When the first support portion 35 or the second support portion 37 of the terminal 30 moves in the pitch direction, it abuts against the restriction wall 286. That is, each of the restriction walls 286 in this embodiment restricts the movement of the first support portion 35 and the second support portion 37 in the pitch direction, thereby ensuring that the main contact 36 and the pressed portion 38 move in the width direction. Similarly, each of the restriction walls 286 restricts the movement of the first support portion 45 in the pitch direction, thereby ensuring that the main contact 46 moves in the width direction. However, the present invention is not limited to this. For example, each of the restriction walls 286 may restrict only the movement of the second support portion 37 in the pitch direction.

[0095] Each terminal receiving portion 29 is provided with two upper walls 288. That is, the holding member 20 of this embodiment has the upper walls 288. Each of the upper walls 288 of this embodiment is the upper end of the island-shaped portion 28. Referring to FIGS. 4 and 5, when the second support portion 37 elastically deforms, the upper end of the second support portion 37 is pressed against the upper walls 288. When the connector 12 is in the mated state, the upper walls 288 press the second support portion 37 downward. As a result, the contact force between the pressed portion 38 and the conductive pad 58 can be sufficiently increased. In addition, when the connector 12 is in the mated state, the upper walls 288 protect the tips of the additional terminals 40 from above. However, the present invention is not limited to this. For example, the upper walls 288 may be provided as needed. [Explanation of symbols]
