Description

[Technical Field]

[0001] The present invention relates to a connector that can be mated with a mating connector, and to a connector assembly that includes the connector and the mating connector. [Background technology]

[0002] This type of connector is disclosed in, for example, Patent Document 1.

[0003] As shown in FIG. 40, a second connector (connector) 900 of Patent Document 1 can be mated with a first connector (mating connector) 950 in the Z direction. The connector 900 includes a second housing (housing) 910 and a plurality of second terminals (terminals) 920. The terminals 920 are held in the housing 910. The terminals 920 include a first contact portion (first contact point) 922 and an extension portion 923. The extension portion 923 is provided with a contact protrusion (lock portion) 924 and a second contact portion (second contact point) 926. The mating connector 950 includes a first housing (mating housing) 960 and a plurality of first terminals (mating terminals) 970. The mating terminals 970 are held in the mating housing 960. The mating terminals 970 include a first contact portion (main contact point) 972 and a second contact portion (support contact point) 976. When the connector 900 and the mating connector 950 are mated with each other, the first contact 922 of the terminal 920 is connected to the main contact 972 of the mating terminal 970, and the second contact 926 of the terminal 920 is connected to the support contact 976 of the mating terminal 970. Furthermore, when the connector 900 and the mating connector 950 are mated with each other, the locking portion 924 of the terminal 920 engages with the support contact 976 of the mating terminal 970. In other words, the support contact 976 of the mating terminal 970 also functions as a mating locking portion that engages with the locking portion 924. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5553502 Summary of the Invention [Problem to be solved by the invention]

[0005] If the insertion force required to mate a connector with a mating connector is too large, problems may arise such as damage to the terminals and housing, etc. Therefore, there is a demand for reducing the insertion force required to mate a connector with a mating connector.

[0006] On the other hand, from the viewpoint of electrical reliability, it is desirable that when a connector and a mating connector are mated, the terminals and the mating terminals are in contact as designed.

[0007] An object of the present invention is to provide a connector that requires a small insertion force when mated with a mating connector, while still being able to obtain electrical contact as designed when mated with the mating connector. [Means for solving the problem]

[0008] In the mating connector 970 of Patent Document 1, the main contacts 972 are supported by springs that are softer than the support contacts 976, and therefore the force with which the support contacts 976 press the terminals 920 is greater than the force with which the main contacts 972 press the terminals 920. In particular, in the mating connector 950 of Patent Document 1, the support contacts 976 also function as a mating locking section, and therefore the reaction force when the contact protrusions 924 of the terminals 920 climb over the support contacts 976 is large, and the insertion force when mating the connector 900 to the mating connector 950 is high.

[0009] To avoid this problem, terminals 920 may be configured to be elastically deformable so as to reduce the difference between the force applied to terminals 920 from support contacts 976 and the force applied to terminals 920 from main contacts 972 when connector 900 is inserted into mating connector 950. Specifically, this problem can be avoided by providing a gap between extension portion 923, on which second contacts 926 are provided, and housing 910, making extension portion 923 elastically deformable.

[0010] On the other hand, if extension 923 of terminal 920 is made elastically deformable, a new problem arises in that the position of second contact 926 in the X direction may become unstable. To avoid this new problem, the applicant devised a method of intentionally bringing the +Z side portion of extension 923 into contact with housing 910 to position second contact 926 in the X direction with high precision, thereby completing the present invention.

[0065] As shown in FIG. 15, the housing 200 is formed with a plurality of holes 240 that penetrate the housing 200 in the vertical direction.

[0066] As shown in Fig. 13, each of the holes 240 in this embodiment is provided in the island-shaped portion accommodating portion 250. As shown in Fig. 15, each of the holes 240 penetrates the upper surface 252 of the island-shaped portion accommodating portion 250 in the vertical direction.

[0067] As shown in FIG. 15, the housing 200 has a plurality of elongated holes 280 formed therein.

[0068] As shown in Fig. 15, each of the elongated holes 280 in this embodiment penetrates the upper surface 252 of the island-shaped portion accommodating portion 250 in the vertical direction. As shown in Fig. 11, each of the elongated holes 280 is provided inside the island-shaped portion accommodating portion 250. As shown in Fig. 15, the elongated hole 280 has a closed periphery in a plane perpendicular to the vertical direction. The elongated hole 280 has a second retaining portion 282.

[0069] 15, the second retaining portion 282 in this embodiment is located at the outer end in the width direction of the elongated hole 280. The second retaining portion 282 is composed of two grooves facing each other in the pitch direction. As described above, the elongated hole 280 in which the second retaining portion 282 is provided has a closed periphery in a plane perpendicular to the up-down direction, and therefore the inner ends in the width direction of the two grooves that make up the second retaining portion 282 are connected by the periphery of the elongated hole 280.

[0070] As shown in Fig. 11, the terminals 400, 500 of this embodiment are aligned in the pitch direction. More specifically, the terminals 400, 500 are aligned in two rows, a front row and a rear row, in the width direction. The terminals 400, 500 in each row are aligned in the pitch direction. The two rows of terminals 400, 500 correspond to the two long wall portions 220, respectively. As can be seen from Figs. 21 and 25, the terminals 400, 500 include first terminals 400 and second terminals 500 of different shapes.

[0071] 18, in each row, the first terminals 400 and the second terminals 500 are arranged alternately in the pitch direction. That is, the first terminals 400 and the second terminals 500 are adjacent to each other in the pitch direction.

[0072] 11, the first terminals 400 of this embodiment are arranged in a staggered pattern in two rows of terminals 400, 500. The first terminals 400 are attached to the housing 200. The first terminals 400 are attached to the long wall portion 220.

[0073] As shown in FIG. 21, the first terminal 400 has an insertion end 410, and a first extension 420 and a second extension 440 that extend vertically from the insertion end 410.

[0074] As shown in FIG. 21 , the insertion end 410 of this embodiment is U-shaped. That is, when the first terminal 400 is viewed along the pitch direction, the insertion end 410 has a U-shape. The insertion end 410 defines the lower end of the first terminal 400 in the up-down direction. As shown in FIG. 13 , the allowing portion 322 is closer to the insertion end 410 than the restraining portion 324 in the up-down direction. The lower end of the interposing portion 300 is not in contact with the insertion end 410. That is, the lower end of the allowing portion 322 is not in contact with the insertion end 410.

[0075] As shown in Fig. 21, the first extension portion 420 in this embodiment extends in the up-down direction from the insertion end portion 410. That is, the first extension portion 420 extends upward in the up-down direction from the insertion end portion 410. As shown in Fig. 13, the first side portion 310 faces the first extension portion 420 in the width direction. The first side portion 310 is in contact with the first extension portion 420. That is, the first side portion 310 is in contact with the first extension portion 420 in the width direction.

[0076] 21, the first extending portion 420 is provided with a first contact point 422. The first extending portion 420 is not provided with a locking portion.

[0077] 13 and 14, the first contacts 422 of the present embodiment face inward in the width direction. As shown in Figures 5 and 6, the first contacts 422 come into contact with the mating terminals 820 when the connector 100 is mated with the mating connector 800. Specifically, the first contacts 422 come into contact with the main contacts 828 when the connector 100 is mated with the mating connector 800.

[0078] As shown in Fig. 21, the second extension portion 440 of this embodiment extends in the up-down direction from the insertion end portion 410. That is, the second extension portion 440 extends upward in the up-down direction from the insertion end portion 410. The first extension portion 420 is located on the inner side of the second extension portion 440 in the width direction. As shown in Fig. 13, the second side portion 320 faces the second extension portion 440 in the width direction. A portion of the second side portion 320 contacts a portion of the second extension portion 440 in the width direction.

[0079] As shown in FIG. 13, the interposition portion 300 is located between the first extension portion 420 and the second extension portion 440 in the width direction.

[0080] 13, a gap 700 is provided between the allowing portion 322 and the second extending portion 440 in the width direction. That is, the allowing portion 322 is positioned away from the second extending portion 440 in the width direction. The allowing portion 322 allows the second extending portion 440 to move partially into the gap 700. As a result, referring to FIGS. 5 and 13, in the initial stage of mating between the connector 100 and the mating connector 800, the second extending portion 440 partially bends toward the allowing portion 322, and the insertion end portion 410 moves toward the first extending portion 420, making it easier for the connector 100 to move over the support contacts 824. of The insertion force is reduced.

[0081] In connector 900 of Patent Document 1, extension 923 is slightly spaced from housing 910, and the distance between extension 923 and housing 910 may vary during manufacturing. This poses a problem in that when connector 900 and mating connector 950 are mated, it is difficult to achieve the designed electrical contact of second contact point 926 with mating terminal 970.

[0082] 13, in connector 100 of the present embodiment, restraint portion 324 is in contact with second extension portion 440 in the width direction with no gap therebetween, and restrains movement of second extension portion 440 in the width direction. As a result, as shown in FIGS. 5 and 13, positioning of second contacts 442 with respect to mating terminals 820 can be performed with high accuracy when connector 100 and mating connector 800 are mated. That is, unlike connector 900 of Patent Document 1, connector 100 of the present embodiment can obtain designed electrical contact of second contacts 442 with mating terminals 820 when mated with mating connector 800.

[0083] As shown in FIG. 21, the second extending portion 440 is provided with a second contact point 442 .

[0084] As shown in Fig. 19, the second contacts 442 of this embodiment face outward in the width direction. As shown in Fig. 5, the second contacts 442 come into contact with the mating terminals 820 when the connector 100 is mated with the mating connector 800. Specifically, the second contacts 442 come into contact with the support contacts 824 when the connector 100 is mated with the mating connector 800. As shown in Fig. 13, the position of the second contacts 442 does not overlap with the restraint portion 324 in the up-down direction.

[0085] 13 and 30, distance D1 on terminal 400 from the portion of terminal 400 corresponding to restraining portion 324 to second contact 442 is shorter than distance D2 on mating terminal 820 from mating restrained portion 822 to support contact 824. As a result, referring to FIG. 5, when connector 100 and mating connector 800 are fully mated, second contact 442 is less likely to move than support contact 824, so that positioning of second contact 442 of first terminal 400 of connector 100 relative to mating first terminal 820 of mating connector 800 can be performed with higher accuracy. Therefore, in connector 100 of the present embodiment, when mated with mating connector 800, electrical contact of second contact 442 with mating terminal 820 as designed can be more easily achieved.

[0086] As shown in FIG. 19, the second extending portion 440 is provided with a locking portion 444 .

[0087] As described above, the second extension portion 440 is provided with the locking portion 444, and the first extension portion 420 is not provided with a locking portion, but the present invention is not limited to this. That is, instead of providing the locking portion 444 on the second extension portion 440, a locking portion may be provided on the first extension portion 420. Furthermore, while the second extension portion 440 is provided with the locking portion 444, the first extension portion 420 may also be provided with a locking portion.

[0088] 5, locking portion 444 of the present embodiment is for locking the mating of connector 100 and mating connector 800. More specifically, with reference to FIGS. 5 and 30, when connector 100 and mating connector 800 are mated with each other, locking portion 444 and mating locking portion 827 lock the mating.

[0089] As shown in FIG. 19, the second extending portion 440 has a pressure applying portion 446 .

[0090] As shown in Fig. 19, the pressure applying portion 446 in this embodiment is located at the upper end of the second extending portion 440.

A portion of the pressing portion 446 is located below the first press-fitted portions 460 in the up-down direction. As shown in Fig. 13 , a portion of the restraining portion 324 is located below the first press-fitted portions 460 in the up-down direction. The first press-fitted portions 460 are press-fitted into the holes 240, respectively. That is, the first press-fitted portions 460 of the first terminals 400 in each row are press-fitted into the holes 240 provided on the inner side in the width direction of the corresponding long wall portions 220.

[0093] As shown in FIG. 21, the first terminal 400 has a first mounting portion 470.

[0094] 21, the first mounting portion 470 in this embodiment extends from the second extending portion 440. Specifically, the first mounting portion 470 extends outward in the width direction from the second extending portion 440. The first mounting portion 470 defines the outer end of the first terminal 400 in the width direction. The first mounting portion 470 defines the upper end of the first terminal 400 in the up-down direction.

[0095] As shown in FIG. 21, the first terminal 400 has an interposition portion accommodating portion 480 .

[0096] 21, the interposition portion accommodating portion 480 in this embodiment is located between the first extending portion 420 and the second extending portion 440 in the width direction. The interposition portion accommodating portion 480 is located above the insertion end portion 410 in the up-down direction. As can be seen from FIGS. 13 and 21, when the first terminal 400 is attached to the housing 200, the interposition portion 300 is accommodated in the interposition portion accommodating portion 480.

[0097] 13 and 22, before first terminal 400 is attached to housing 200, distance D3 in the width direction between first press-fit portion 460 and pressure portion 446 is smaller than size S in the width direction of interposition portion 300. As a result, referring to Figures 13, 21 and 22, when first terminal 400 is attached to housing 200, interposition portion 300 is accommodated in interposition portion accommodating portion 480 of first terminal 400 while increasing distance D3 in the width direction between first press-fit portion 460 and pressure portion 446, and when first terminal 400 is attached to housing 200, pressure portion 446 is in pressure contact with restraint portion 324.

[0098] 11, the second terminals 500 of this embodiment are arranged in a staggered manner in two rows of the terminals 400, 500. The second terminals 500 are attached to the housing 200. The second terminals 500 are attached to the long wall portion 220.

[0099] As shown in FIG. 25, the second terminal 500 has an insertion end 510, and a first extension 520 and a second extension 540 that extend vertically from the insertion end 510.

[0100] As shown in Figure 25, the insertion end 510 of this embodiment is U-shaped. 2When the terminal 500 is viewed along the pitch direction, the insertion end 510 has a U-shape. The insertion end 510 defines the bottom end of the second terminal 500 in the up-down direction. As shown in FIG. 14 , the allowing portion 322 is closer to the insertion end 510 than the restraining portion 324 in the up-down direction. The bottom end of the interposing portion 300 is not in contact with the insertion end 510. That is, the bottom end of the allowing portion 322 is not in contact with the insertion end 510.

[0101] As shown in Fig. 25, the first extension portion 520 in this embodiment extends in the up-down direction from the insertion end portion 510. That is, the first extension portion 520 extends upward in the up-down direction from the insertion end portion 510. As shown in Fig. 14, the first side portion 310 faces the first extension portion 520 in the width direction. The first side portion 310 is in contact with the first extension portion 520. That is, the first side portion 310 is in contact with the first extension portion 520 in the width direction.

[0102] As shown in FIG. 12, the first extending portions 520 and the second extending portions 440 are alternately arranged on the first wall surface 222 in the pitch direction.

[0103] 25, the first extending portion 520 is provided with a first contact point 522. The first extending portion 520 is not provided with a locking portion.

[0104] 13 and 14, the first contacts 522 of this embodiment face outward in the width direction. As shown in Figures 5 and 6, the first contacts 522 come into contact with the mating terminals 850 when the connector 100 is mated with the mating connector 800. Specifically, the first contacts 522 come into contact with the main contacts 858 when the connector 100 is mated with the mating connector 800.

[0105] As shown in Fig. 25, the second extension portion 540 in this embodiment extends in the up-down direction from the insertion end portion 510. That is, the second extension portion 540 extends upward in the up-down direction from the insertion end portion 510. The second extension portion 540 is located on the inner side of the first extension portion 520 in the width direction. As shown in Fig. 14, the second side portion 320 faces the second extension portion 540 in the width direction. A portion of the second side portion 320 contacts a portion of the second extension portion 540 in the width direction.

[0106] As shown in FIG. 14, the interposition portion 300 is located between the first extension portion 520 and the second extension portion 540 in the width direction.

[0107] 14, a gap 700 is provided between the allowing portion 322 and the second extending portion 540 in the width direction. That is, the allowing portion 322 is positioned away from the second extending portion 540 in the width direction. The allowing portion 322 allows the second extending portion 540 to move partially into the gap 700. As a result, referring to FIGS. 6 and 14, in the initial stage of mating between the connector 100 and the mating connector 800, the second extending portion 540 partially bends toward the allowing portion 322, and the insertion end portion 510 moves toward the first extending portion 520, making it easier for the connector 100 to move over the support contacts 854. of Insertion Force of Efforts are being made to reduce this.

[0108] 14, in connector 100 of the present embodiment, restraint portion 324 is in contact with second extension portion 540 in the width direction with no gap therebetween, and restrains movement of second extension portion 540 in the width direction. As a result, as shown in FIGS. 6 and 14, positioning of second contacts 542 with mating terminals 850 can be performed with high accuracy when connector 100 and mating connector 800 are mated. That is, unlike connector 900 of Patent Document 1, connector 100 of the present embodiment can obtain designed electrical contact of second contacts 542 with mating terminals 850 when mated with mating connector 800.

[0109] As shown in FIG. 10, the first extending portions 420 and the second extending portions 540 are alternately arranged on the second wall surface 224 in the pitch direction.

[0110] As shown in FIG. 25, the second extending portion 540 is provided with a second contact point 542 .

[0111] As shown in Fig. 14, the second contacts 542 in this embodiment face inward in the width direction. As shown in Fig. 6, the second contacts 542 come into contact with the mating terminals 850 when the connector 100 is mated with the mating connector 800. Specifically, the second contacts 542 come into contact with the support contacts 854 when the connector 100 is mated with the mating connector 800. As shown in Fig. 14, the position of the second contacts 542 does not overlap with the restraining portions 324 in the up-down direction.

[0112] 14 and 31, distance D1 on terminal 500 from the portion of terminal 500 corresponding to restraining portion 324 to second contact 542 is shorter than distance D2 on mating terminal 850 from mating restrained portion 852 to support contact 854. As a result, referring to FIG. 6, when connector 100 and mating connector 800 are fully mated, second contact 542 is less likely to move than support contact 854, so that positioning of second contact 542 of second terminal 500 of connector 100 relative to mating second terminal 850 of mating connector 800 can be performed with higher accuracy. Therefore, in connector 100 of the present embodiment, when mated with mating connector 800, electrical contact of second contact 542 with mating terminal 850 as designed can be more easily achieved.

[0113] As shown in FIG. 25, the second extending portion 540 is provided with a locking portion 544 .

[0114] As described above, the second extension portion 540 is provided with the locking portion 544, and the first extension portion 520 is not provided with a locking portion, but the present invention is not limited to this. That is, instead of providing the locking portion 544 on the second extension portion 540, a locking portion may be provided on the first extension portion 520. Furthermore, while the second extension portion 540 is provided with the locking portion 544, the first extension portion 520 may also be provided with a locking portion.

[0115] 6, locking portion 544 of the present embodiment is for locking the mating of connector 100 and mating connector 800. More specifically, with reference to FIGS. 6 and 31, when connector 100 and mating connector 800 are mated with each other, locking portion 544 and mating locking portion 857 lock the mating.

[0116] As shown in FIG. 25, the first extending portion 520 has a pressure applying portion 526 .

[0117] As shown in Fig. 25, the pressure applying portion 526 in this embodiment is located at the upper end of the first extension portion 520. The pressure applying portion 526 is located near the upper end of the second terminal 500. As shown in Fig. 14, the pressure applying portion 526 is located at the same position as the restraining portion 324 in the up-down direction. The pressure applying portion 526 is located above the allowing portion 322 in the up-down direction. The pressure applying portion 526 is in contact with the first side portion 310 in the width direction.

[0118] As shown in FIG. 25, second terminal 500 of the present embodiment has second press-fit portion 560. As shown in FIG.

[0119] 25, the second press-fitted portion 560 in this embodiment is provided on the second extending portion 540. More specifically, the second press-fitted portion 560 is located at the upper end of the second extending portion 540 in the up-down direction. A portion of the pressure applying portion 526 is located below the second press-fitted portion 560 in the up-down direction. As shown in FIG. 14, a portion of the restraint portion 324 is located below the second press-fitted portion 560 in the up-down direction.

[0120] 14 and 15, the second press-fit portions 560 are press-fitted into the second holding portions 282. That is, the second press-fit portions 560 of the second terminals 500 in each row are press-fitted into the second holding portions 282 provided on the inner side in the width direction of the corresponding long wall portions 220.

[0121] As described above, the inner ends in the width direction of the two grooves that make up second retaining portion 282 are connected by the periphery of elongated hole 280. This prevents the distance in the pitch direction between the inner ends in the width direction of the two grooves of second retaining portion 282 from widening when second press-fitted portion 560 is press-fitted into second retaining portion 282, thereby maintaining retention of second retaining portion 282 against second press-fitted portion 560.

[0122] As described above, in the first terminal 400 of this embodiment, the first press-fit portion 460 is provided on the first extension portion 420 located on the widthwise inner side of the second extension portion 440, and in the second terminal 500 of this embodiment, the second press-fit portion 560 is provided on the second extension portion 540 located on the widthwise inner side of the first extension portion 520. As a result, in the connector 100 of this embodiment, the process of attaching the terminals 400, 500 to the housing 200 can be simplified as follows: with the first terminals 400 and the second terminals 500 arranged alternately in the pitch direction, a blank is formed in which the outer ends of the terminals 400, 500 in the widthwise direction and the carrier are connected via connecting portions. ; The first terminal 400 and the second terminal 500, which are connected to each other by a carrier, are simultaneously attached to the housing 200; the connection between the terminals 400, 500 and the carrier is severed, thereby separating the terminals 400, 500 from the carrier.

[0123] As shown in FIG. 25, the second terminal 500 has a second mounting portion 570.

[0124] 25, the second mounting portion 570 in this embodiment extends from the second extending portion 540. Specifically, the second mounting portion 570 extends inward in the width direction from the second extending portion 540. The second mounting portion 570 defines the inner end of the second terminal 500 in the width direction. The second mounting portion 570 defines the upper end of the second terminal 500 in the up-down direction. With reference to FIGS. 8 and 14, the second mounting portion 570 is soldered to a pad on the substrate 750.

[0125] As shown in FIG. 25, the second terminal 500 has an interposition portion accommodating portion 580 .

[0126] 25, the interposition portion accommodating portion 580 in this embodiment is located between the first extending portion 520 and the second extending portion 540 in the width direction. The interposition portion accommodating portion 580 is located above the insertion end portion 510 in the up-down direction. As can be seen from FIGS. 14 and 25, when the second terminal 500 is attached to the housing 200, the interposition portion 300 is accommodated in the interposition portion accommodating portion 580.

[0127] 14 and 26, before second terminal 500 is attached to housing 200, distance D4 in the width direction between second press-fit portion 560 and pressure portion 526 is smaller than size S in the width direction of interposition portion 300. Thus, referring to Figures 14, 25 and 26, when second terminal 500 is attached to housing 200, interposition portion 300 is accommodated in interposition portion accommodating portion 580 of second terminal 500 while increasing distance D4 in the width direction between second press-fit portion 560 and pressure portion 526, and when second terminal 500 is attached to housing 200, pressure portion 526 is in pressure contact with first side portion 310.

[0128] 13 and 14, the first press-fitted portions 460 and the second press-fitted portions 560 are positioned to correspond to each other in the width direction, and are arranged alternately in the pitch direction.

[0129] Although the present invention has been specifically described above by presenting an embodiment, the present invention is not limited to this and various modifications are possible.

[0130] In the above-described embodiment, the first press-fitted portions 460 are provided at the end of the first extending portion 420, and the first press-fitted portions 460 of the first terminals 400 in each row are press-fitted into the holes 240 provided on the inner side in the width direction of the corresponding long wall portion 220, but the present invention is not limited to this. That is, the connector 100 may be modified as follows: the first press-fitted portions 460 are provided at the end of the second extending portion 440; and the first press-fitted portions 460 of the first terminals 400 in each row are held by holding portions provided on the outer side in the width direction of the corresponding long wall portion 220.

[0131] In the above-described embodiment, the second press-fitted portions 560 are provided on the second extension portion 540, and the second press-fitted portions 560 of the second terminals 500 in each row are press-fitted into the second holding portions 282 provided on the inside in the width direction of the corresponding long wall portion 220, but the present invention is not limited to this. That is, the connector 100 may be modified as follows: the second press-fitted portions 560 are provided on the first extension portion 520; and the second press-fitted portions 560 of the second terminals 500 in each row are held by holding portions provided on the outside in the width direction of the corresponding long wall portion 220.

[0132] Although the first mounting portion 470 in the above-described embodiment extends outward in the width direction from the second extension portion 440, the present invention is not limited thereto. That is, the first mounting portion 470 may extend inward in the width direction from the first extension portion 420. Note that the second extension portion 440 is provided with a locking portion 444. When the connector 100 mounted on the substrate 750 is removed from the mating connector 800, a force is applied from the mating locking portion 827 to the locking portion 444 in a direction away from the substrate 750. However, in the present embodiment, the first mounting portion 470 fixed to the substrate 750 extends from the second extension portion 440. Therefore, the first terminal 400 can be firmly fixed to the substrate 750 against the force applied to the locking portion 444. Therefore, the first mounting portion 470 in the present embodiment is more preferable.

[0133] Although the second mounting portion 570 in the above-described embodiment extends inward in the width direction from the second extension portion 540, the present invention is not limited thereto. That is, the second mounting portion 570 may extend outward in the width direction from the first extension portion 520. The second extension portion 540 is provided with a locking portion 544. When the connector 100 mounted on the substrate 750 is removed from the mating connector 800, a force is applied from the mating locking portion 857 to the locking portion 544 in a direction away from the substrate 750. However, in the present embodiment, the second mounting portion 570 fixed to the substrate 750 extends from the second extension portion 540. Therefore, the second terminal 500 can be firmly fixed to the substrate 750 against the force applied to the locking portion 544. Therefore, the second mounting portion 570 in the present embodiment is more preferable.

[0134] In the first terminal 400 of the above-described embodiment, the position of the second contact 442 does not overlap with the restraining portion 324 in the vertical direction, but the present invention is not limited to this. That is, the position of the second contact 442 may overlap with the restraining portion 324 in the vertical direction. This makes it more difficult for the second contact 442 to move relative to the interposition portion 300, so that when the connector 100 and the mating connector 800 are fully mated, the second contact 442 of the first terminal 400 of the connector 100 can be positioned with higher accuracy relative to the mating first terminal 820 of the mating connector 800, making it easier to obtain the designed contact force between the mating first terminal 820 and the second contact 442.

[0135] In the second terminal 500 of the above-described embodiment, the position of the second contact 542 does not overlap with the restraining portion 324 in the vertical direction, but the present invention is not limited to this. That is, the position of the second contact 542 may overlap with the restraining portion 324 in the vertical direction. This makes it more difficult for the second contact 542 to move relative to the interposition portion 300, so that when the connector 100 and the mating connector 800 are fully mated, the second contact 542 of the second terminal 500 of the connector 100 can be positioned with higher accuracy relative to the mating second terminal 850 of the mating connector 800, making it easier to obtain the designed contact force between the mating second terminal 850 and the second contact 542.
