[Modes for carrying out the invention]

[0017] Referring to Figures 1 and 2, the connecting device 10 according to an embodiment of the present invention comprises 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. In this embodiment, the vertical direction 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 inside, for example, an electronic device (not shown). However, the present invention is not limited thereto and is applicable to various connecting devices 10.

[0018] The following describes the opposing assembly 61 of this embodiment.

[0019] As shown in Figures 1, 6, and 7, the mating assembly 61 of this embodiment comprises a mating substrate 66 and a mating connector 62. The mating connector 62 is mounted and fixed to the mating substrate 66. However, the present invention is not limited thereto. For example, the mating assembly 61 may further comprise other components in addition to the components described above.

[0020] Referring to Figures 6 and 7, the mating connector 62 of this embodiment comprises a mating holding member 70 made of an insulator and 20 (i.e., 2 or more) mating terminals 80 made of a conductor. The mating connector 62 has a mating receiving portion 64 formed therein. The mating receiving portion 64 is a space that is recessed upward and opens downward. However, the present invention is not limited thereto. For example, the mating connector 62 may have only one mating terminal 80. On the other hand, the mating connector 62 may further comprise other members in addition to the above-described members.

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

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

[0023] Referring to Figure 7, the mating terminal 80 in this embodiment includes 10 (i.e., 2 or more) first terminals 80F and 10 (i.e., 2 or more) second terminals 80S. In other words, the mating terminal 80 includes two types of mating terminals 80. The first terminals 80F and the second terminals 80S have the same structure, although their shapes are slightly different.

[0024] Referring to Figures 8 and 9, each mating terminal 80 in this embodiment is a single metal plate with a bend. Each mating terminal 80 has a mating fixed portion 82 and a mating contact portion 84. Each mating fixed portion 82 is located at the upper end of the mating terminal 80 and extends along the width direction. Each mating contact portion 84 extends downward from the mating fixed portion 82. Each mating contact portion 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 to the connector 12 (see Figure 1).

[0025] Each of the mating terminals 80 in this embodiment has the structure described above. However, the present invention is not limited thereto. For example, the shapes of the first terminal 80F and the second terminal 80S may be the same. That is, the mating terminal 80 may include only one type of mating terminal 80. On the other hand, the mating terminal 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 Figure 7, the mating terminal 80 in this embodiment is divided into two rows in the width direction. In other words, the mating connector 62 has two rows of mating terminals. In each of the mating terminal rows, 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 180 degrees rotationally symmetrically with respect to an axis parallel to the vertical direction. The first terminals 80F of one of the mating terminal rows are aligned in the width direction with the second terminals 80S of the other terminal row 16. The mating terminals 80 in this 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 mating contact portion 84 in this embodiment is insert-molded into the side wall 75 and is thereby held by the mating holding member 70. Referring to Figures 8 and 9, in each mating contact portion 84, one of the two contact surfaces 86 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 thereto. For example, each mating contact portion 84 may be press-fitted into the side wall 75.

[0028] Referring to Figure 7, the mating portion 82 of the mating terminal 80 is divided into four rows in the width direction. Two of the four rows contain only the mating portion 82 of the first terminal 80F, and the other two rows contain only the mating portion 82 of the second terminal 80S. When the mating connector 62 is viewed along the vertical direction, the two rows of mating portions 82 of the first terminal 80F are located inside the peripheral wall 74, and the two rows of mating portions 82 of the second terminal 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 portions 82 are arranged in the pitch direction. The mating portions 82 in this embodiment are arranged as described above. However, the arrangement of the mating portions 82 in the present invention is not particularly limited.

[0029] Referring to Figure 10, the lower surface of the mating substrate 66 in this embodiment is provided with 20 (i.e., 2 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 so as to correspond to the mating fixed portion 82 of the mating terminal 80. 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 arranged along the pitch direction. When mounting the mating connector 62 (see Figure 7) onto the mating substrate 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 by soldering. As a result, the mating connector 62 is fixed to the mating substrate 66 and electrically connected to the mating substrate 66.

[0031] The opposing resist 69 surrounds the opposing conductive pad 68 in the XY plane, preventing short circuits of the opposing fixed part 82 during soldering.

[0032] The mating substrate 66 in this embodiment is a rigid circuit board having the structure described above. However, the present invention is not limited thereto. For example, the mating substrate 66 may be a flexible printed circuit board (FPC). In this case, the mating substrate 66 may be reinforced with a reinforcing plate (not shown).

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

[0034] Referring to Figure 1, the assembly 11 of this embodiment comprises 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. Furthermore, the connector 12 can be fixed to the main surface 52 by the fixing mechanism 40. The assembly 11 of this embodiment comprises only the above-described components. However, the present invention is not limited thereto. For example, the assembly 11 may further comprise other components in addition to the above-described components.

[0035] Referring to Figures 1 and 2, the main surface 52 in this embodiment is the upper surface of the substrate 50 and is a plane extending parallel to the XY plane. The connector 12 in this embodiment is matable with a mating connector 62 equipped with mating terminals 80 in the vertical direction perpendicular to the main surface 52. However, the present invention is not limited thereto. For example, the main surface 52 may be a plane that intersects the XY plane at an angle. That is, the connector 12 only needs to be matable with a mating connector 62 equipped with mating terminals 80 in the vertical direction intersecting the substrate 50 (more specifically, the main surface 52).

[0036] As described above, the connector 12 and the mating connector 62 in this embodiment are so-called onboard 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] Referring to Figures 1, 14, and 15, the connector 12 of this embodiment comprises a retaining member 20 made of an insulator, 10 (i.e., 2 or more) terminals 30 made of a conductor, and 10 (i.e., 2 or more) additional terminals (fixing mechanisms) 40 made of a conductor. The connector 12 has a receiving portion 14 formed therein. The receiving portion 14 is a recessed space that opens upward. However, the present invention is not limited thereto. For example, the connector 12 may have only one terminal 30. Additional terminals 40 may be provided as needed. On the other hand, the connector 12 may further comprise other members in addition to the above-described members.

[0038] Referring to Figures 14 and 15, the retaining member 20 of this embodiment has a bottom portion 22, an outer peripheral portion 24, and an island-shaped portion 28. The bottom portion 22 is located at the lower end of the retaining member 20. The outer peripheral portion 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 peripheral portion 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 of the end walls 26 connects the two side portions 25 to each other in the width direction.

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

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

[0041] The following describes the structure of one of the terminals 30 in this embodiment. 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 holding 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 pressing portion 38.

[0043] The lower end portion 31 is located at the lower end of the terminal 30 and extends along the width direction. The retained portion 32 extends upward from the end of the lower end portion 31 in the width direction. The retained portion 32 has two press-fit protrusions 322 (see Figure 15) that project outwards on both sides in the pitch direction. The connecting portion 33 extends from the upper end of the retained portion 32 away from the lower end portion 31 along the width direction. The auxiliary contact 34 is provided at the end of the connecting portion 33 in the width direction. That is, the connecting portion 33 connects the retained portion 32 and the auxiliary contact 34 to each other in the width direction. The auxiliary contact 34 protrudes away from the lower end portion 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 the 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 is mainly movable in the YZ plane as the first support portion 35 elastically deforms. The first support portion 35 in this embodiment has a U shape and is easily elastically deformable.

[0045] More 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 structure that is easily flexible. The main contact 36 of this embodiment is movable in the vertical and width directions. However, the present invention is not limited thereto. The structure of the first support portion 35 can be deformed as needed. The main contact 36 only needs to be movable in the width 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 circular 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 the 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 is mainly movable in 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 of 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 in the same position as the lower end of the lower end portion 31 in the vertical direction.

[0049] In the vertical arm portion 372 of this embodiment, the size HV in the vertical direction is greater than the size WV in the width direction. In the horizontal arm portion 374 of this embodiment, the size WH in the width direction is greater than the size HH in the vertical direction. 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 distance in the width direction between the main contact 36 and the pressed portion 38. As a result, the springiness of the second support portion 37 can be improved while reducing the size of the terminal 30 in the width direction.

[0050] The second support portion 37 of this embodiment has a long spring length and 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 thereto, and the structure of the second support portion 37 can be modified as needed. For example, the second support portion 37 may have only a 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 of each terminal 30 are the parts that are electrically connected to the mating connector 62 (see Figure 1). However, the present invention is not limited thereto. As long as each of the terminals 30 has an elastically deformable first support part 35, a main contact 36 supported by the first support part 35, an elastically deformable second support part 37, and a pressed part 38 supported by the second support part 37, the structure of each of the terminals 30 can be deformed as needed. For example, the auxiliary contact 34 may be provided as needed.

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

[0053] The following describes the structure of one of the additional terminals 40 in this embodiment. 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 retained portion 42 extends upward from the end of the fixed portion 41 in the width direction. The retained portion 42 has two press-fit protrusions 422 (see Figure 15) that project outwards on both sides in the pitch direction. The connecting portion 43 extends from the upper end of the retained portion 42 away from the fixed portion 41 along the width direction. The auxiliary contact 44 is provided at the end of the connecting portion 43 in the width direction. That is, the connecting portion 43 connects the retained portion 42 and the auxiliary contact 44 to each other in the width direction. The auxiliary contact 44 protrudes away from the fixed portion 41 in the width direction.

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

[0057] More 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 in this embodiment has a long spring length and a structure that is easily flexible. The main contact point 46 in this embodiment is movable in the vertical and width directions. However, the present invention is not limited thereto. For example, the first support portion 45 may have a structure that is relatively resistant to bending.

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

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

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

[0062] Referring to Figures 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 arranged alternately along the pitch direction. However, the present invention is not limited thereto. For example, the connector 12 may have only one terminal row 16, or it may have three or more terminal rows 16. Also, 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 arranged alternately along the pitch direction.

[0063] Referring to Figure 11, the terminals 30 and additional terminals 40 in the two terminal rows 16 of this embodiment are arranged 180 degrees rotationally symmetrically with respect to an axis parallel to the vertical direction (an axis extending along the vertical direction, passing through the center point 18 drawn in Figure 18). One terminal 30 of the terminal row 16 is aligned in the width direction with the other additional terminal 40 of the terminal row 16. Referring to Figure 3, the terminals 30 are positioned in the XY plane to correspond to the first terminal 80F of the mating connector 62. The additional terminals 40 are positioned in the XY plane to correspond to the second terminal 80S of the mating connector 62.

[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 have only one terminal 30 and one first terminal 80F, respectively, which are located at corresponding positions in the XY plane.

[0065] Referring to Figures 14 and 15, the two terminal rows 16 in this embodiment are attached to the two sides 25, respectively, as will be described below.

[0066] Each side portion 25 of this embodiment has 10 retaining grooves 252 formed thereon. That is, the retaining member 20 has two rows of retaining grooves 252 formed thereon. The retaining grooves 252 in each row are arranged in the pitch direction. In each row, five of the retaining grooves 252 are for holding terminals 30, and the other five retaining grooves 252 are for holding additional terminals 40. Each of the retaining grooves 252 penetrates the side portion 25 in the vertical direction and opens downwards.

[0067] The retaining member 20 of this embodiment has 10 terminal receiving portions 29 formed thereon. The terminal receiving portions 29 are arranged 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 retaining 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 in the width direction with one of the additional terminals 40. In other words, each of the terminal receiving portions 29 receives one terminal 30 and one additional terminal 40. Each of the retained portions 32 of the terminals 30 is press-fitted into the corresponding retaining groove 252 and held in place. Similarly, each of the retained portions 42 of the additional terminals 40 is press-fitted into the corresponding retaining groove 252 and held in place. That is, 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 10 intermediate walls 284, each corresponding to a terminal receiving portion 29. The intermediate walls 284 are arranged in the pitch direction. Referring to Figures 12 and 13, each intermediate wall 284 is located in 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 Figure 15, as described above, the terminal 30 and the additional terminal 40 in this embodiment are each press-fitted into the holding member 20 from below and held in place. 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 downwards. However, the present invention is not limited thereto. For example, the terminal 30 and the additional terminal 40 may each be insert-molded into the holding member 20 and held in place. In this case, the holding groove 252 does not need to be provided. Also, the terminal receiving portion 29 does not need to be open downwards. The intermediate wall 284 may be provided as needed.

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

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

[0073] Referring to Figure 18, the main surface 52 of the substrate 50 in this embodiment is provided with 20 (i.e., 2 or more) conductive pads 58 made of a conductor and a resist 59 made of an insulator. The substrate 50 comprises one intermediate pad row 54 and two side pad rows 56 corresponding to the terminal row 16, respectively. In the intermediate pad row 54, 10 (i.e., 2 or more) conductive pads 58 are arranged along the pitch direction. In each of the side pad rows 56, 5 (i.e., 1 or more) conductive pads 58 are arranged 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 Figure 11) is mounted on the main surface 52, the additional terminals 40 in each of the terminal rows 16 are fixed to the corresponding conductive pads 58 of the side pad row 56. In this embodiment, each fixed portion 41 of the additional terminals 40 is fixed and connected to the conductive pads 58 by soldering. As a result, the connector 12 is fixed to the substrate 50. The resist 59 surrounds the conductive pads 58 in the XY plane, preventing short circuits of the fixed portions 41 during soldering.

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

[0076] Referring to Figure 14, according to this embodiment, when the terminal 30 and the additional terminal 40 are held by the holding member 20, the lower end of the lower end portion 31 of the terminal 30 and the lower end of the pressed portion 38 are in the same position in the vertical direction as the lower end of the fixed portion 41 of the additional terminal 40. Referring to Figures 12 and 13 in conjunction with Figure 18, with this arrangement, when the additional terminal 40 is fixed to the substrate 50, the lower end portion 31 of the terminal 30 contacts the resist 59 of the substrate 50, and the pressed portion 38 contacts the conductive pad 58 of the intermediate pad row 54, without any part of the terminal 30 being fixed to the substrate 50. As a result, the connector 12 is electrically connected to the substrate 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 portion 41 of the additional terminal 40 is located on both sides of the retaining member 20 in the width direction and is arranged at equal intervals between both sides of the retaining member 20 in the pitch direction. This arrangement allows the connector 12 to be firmly fixed to the substrate 50. However, the present invention is not limited thereto. For example, if the size of the connector 12 is small, the connector 12 may have only one additional terminal 40. Also, the connector 12 may have a hold-down that functions as a 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 retaining member 20. For example, the connector 12 may be fixed to the substrate 50 by a fixing mechanism 40 such as a screw.

[0079] Referring to Figure 12, in this embodiment, the pressed portion 38 of the terminal 30 is positioned to contact the conductive pad 58 without being pressed against it when the connector 12 is fixed to the substrate 50. This embodiment is preferred from the viewpoint of easily soldering the fixed portion 41 to the conductive pad 58 and making the pressed portion 38 contact the conductive pad 58. However, the present invention is not limited thereto. 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 following describes the mating operation when connecting connector 12 to the mating connector 62 (see Figure 1).

[0081] Referring to Figures 1 and 2, the connector 12 of this embodiment can be mated with the mating connector 62 along the vertical direction while fixed to the substrate 50. However, the present invention is not limited thereto. For example, if the connector 12 does not have 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-down mechanisms.

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

[0083] The auxiliary contact 44 of the additional terminal 40 is close to the held portion 42 fixed to the holding member 20, so it hardly moves even when pressurized. On the other hand, the main contact 46 is supported by the highly springy first support portion 45, so it 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 terminal 30 is close to the held portion 32 fixed to the holding member 20, and therefore hardly moves even when pressurized. On the other hand, the main contact 36, supported by the inner arm 354 of the highly springy first support portion 35, receives forces directed inward and downward in the width direction, similar to the main contact 46, and moves in a rotational 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 connector 12 is mated with mating connector 62, the main contact 36 of terminal 30 contacts the mating terminal 80 and moves in the width direction. At this time, the second support portion 37 of terminal 30 is elastically deformed, and as a result, each of the pressed portions 38 moves inward in the width direction while being pressed against the conductive pad 58. That is, when connector 12 is in the mated state with mating connector 62, the pressed portions 38 are pressed against the conductive pad 58 in the vertical direction. Therefore, if the substrate 50 is removed while in the mated state, each of the pressed portions 38 moves below the location where the conductive pad 58 was located.

[0086] Referring to Figure 18 in conjunction with Figure 11, according to this embodiment, when the connector 12 is mated, the pressed portion 38 of the terminals 30 in the two terminal rows 16 is pressed against the conductive pads 58 of the intermediate pad row 54 in the vertical direction. That is, the terminals 30 in this embodiment are connected to the conductive pads 58 not by soldering, but simply by being pressed against the conductive pads 58. With this connection method, two adjacent conductive pads 58 can be placed in very close proximity, thereby enabling a narrower pitch for the terminals 30.

[0087] According to this embodiment, it is possible to provide an assembly 11 including a connector 12 mounted on a substrate 50, having a structure suitable for narrowing the pitch of the terminals 30. By narrowing the pitch of the terminals 30, the size of the connector 12 in the pitch direction can be reduced. In addition, since the process of soldering the terminals 30 is unnecessary, the manufacturing cost of the assembly 11 can be reduced.

[0088] Referring to Figure 11, in this embodiment, the terminals 30 and the additional terminals 40 are arranged alternately in the pitch direction, so that the pressed portion 38 of the terminal 30 can be reliably pressed against the conductive pad 58. However, the present invention is not limited thereto. The arrangement of the terminals 30 and the additional terminals 40 in the pitch direction can be modified as needed.

[0089] Comparing Figures 11 and 18 with Figures 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 size of the mating connector 62 in the width direction. On the other hand, according to this embodiment, the pitch of the pressed portion 38 can be made extremely short, so the conductive pads 58 that the pressed portion 38 contacts can be arranged in a single row along the pitch direction. Therefore, not only the size of the connector 12 in the pitch direction but also the size in the width direction can be reduced. In other words, according to this embodiment, the area occupied by the connector 12 on the main surface 52 of the substrate 50 can be reduced.

[0090] Referring to Figures 4 and 5, according to this embodiment, when the connector 12 is mated, the main contact 36 and auxiliary contact 34 sandwich the mating terminal 80 in the width direction and make contact with the mating terminal 80. That is, terminal 30 makes contact with the mating terminal 80 at two points. With this structure, even if the position of the mating connector 62 in the width direction is shifted, terminal 30 will stably make contact with the mating terminal 80 with the designed contact force. Furthermore, since the pressed portion 38 is not fixed and can move in the width direction, an even more stable contact force can be obtained. Similarly, the additional terminal 40 also makes stably two-point contact with the mating terminal 80.

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

[0092] According to this embodiment, the spring of the horizontal arm 374 located at the lower end of the second support portion 37 allows the contact force between the pressed portion 38 and the conductive pad 58 to be set to a predetermined value or higher without affecting the contact force of the main contact 36, and also reduces variations in the contact force between the pressed portion 38 and the conductive pad 58. However, the present invention is not limited thereto. For example, the horizontal arm 374 is not limited to the lower end of the second support portion 37, but may be provided between the main contact 36 and the pressed portion 38. Also, the horizontal arm 374 may be provided as needed.

[0093] Referring to Figure 15, each terminal receiving portion 29 is provided with two restricting walls 286. That is, the holding member 20 of this embodiment has restricting walls 286. Each of the restricting walls 286 in 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 restricting walls 286 in each terminal receiving portion 29 sandwich the terminal 30 and the additional terminal 40 in the pitch direction.

[0094] Referring to Figures 12 and 13, each of the restricting walls 286 extends between the two sides 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 restricting wall 286. That is, each of the restricting 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 restricting 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 thereto. For example, each of the restricting 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 upper walls 288. Each of the upper walls 288 in this embodiment is the upper end of the island-shaped portion 28. Referring to Figures 4 and 5, when the second support portion 37 undergoes elastic deformation, the upper end of the second support portion 37 is pressed against the upper wall 288. When the connector 12 is in the mated state, the upper wall 288 presses the second support portion 37 downward. As a result, the contact force between the pressed portion 38 and the conductive pad 58 can be made sufficiently large. In addition, when the connector 12 is in the mated state, the upper wall 288 protects the tip of the additional terminal 40 from above. However, the present invention is not limited thereto. For example, the upper walls 288 may be provided as needed. [Explanation of symbols]
