With reference to Figs. 3 and 10, the inner pressure contacts 724 of the second-type second terminals 720 in the rear second terminal row 650 face backward in the front-rear direction.

[0077] As shown in Fig. 3, in the unmated state, the outer pressing contact 723 and the inner pressing contact 724 are spaced apart from each other and face each other in the width direction. In the unmated state, the outer pressing contact 723 and the inner pressing contact 724 are spaced apart from each other in the width direction by a second-type pressing distance D2. As shown in Fig. 8, in the mated state, the outer pressing contact 723 of the second-type second terminal 720 presses the outer pressed contact 323 of the corresponding second-type first terminal 320 in the width direction.

[0079] 18, the support portion 725 of this embodiment elastically supports two pressure contacts 722. The support portion 725 extends from the upper end of the held portion 726.

[0080] 4 and 18, the held portion 726 in this embodiment is held by the second holding member 600. The held portion 726 is press-fitted into the second holding member 600. More specifically, the held portion 726 is press-fitted into the second holding portion 620.

The held portion 726 extends upward in the up-down direction from the outer end of the fixed portion 728 in the width direction.

[0081] Referring to FIG. 4 , the fixed portions 728 of the present embodiment are fixed to an object when the second connector 500 is mounted on the object. Specifically, the fixed portions 728 are soldered to pads (not shown) of a board when the second connector 500 is mounted on the board. As shown in FIG. 18 , the fixed portions 728 define the lower ends of the second-type second terminals 720 in the up-down direction. The fixed portions 728 define the inner ends of the second-type second terminals 720 in the width direction. The fixed portions 728 extend inward in the width direction from the lower ends of the held portions 726. As shown in FIG. 10 , the fixed portions 728 of the second-type second terminals 720 are at least partially located within the openings 605 of the second holding member 600. When the second connector 500 is viewed in the up-down direction, all of the fixed portions 728 of the second-type second terminals 720 are visible through the openings 605. However, the present invention is not limited to this, and when the second connector 500 is viewed in the vertical direction, it is sufficient that the fixed portions 728 of the second type second terminals 720 of at least two or more second terminals 700 are visible through the opening 605.

[0082] As described above, the fixed portions 728 are soldered to pads on the board when the second connector 500 is mounted on the board. Therefore, it is necessary to ensure sufficient spacing between adjacent fixed portions 728 and between the pads to which they are soldered. If the second-type second terminals 720 of the two second terminal rows 650 are arranged rotationally asymmetrically in a plane perpendicular to the up-down direction, the second-type second terminals 720 of the front second terminal row 650 and the second-type second terminals 720 of the rear second terminal row 650 will be arranged back-to-back in the front-to-back direction. However, in this case, it is not possible to ensure sufficient spacing between the fixed portions 728 of the second-type second terminals 720 of the front second terminal row 650 and the fixed portions 728 of the second-type second terminals 720 of the rear second terminal row 650. On the other hand, in the second connector 500 of this embodiment, as described above, the second-type second terminals 720 of the two second terminal rows 650 are arranged with two-fold rotational symmetry in a plane perpendicular to the up-down direction, so the second-type second terminals 720 of the front second terminal row 650 and the second-type second terminals 720 of the rear second terminal row 650 are not arranged back-to-back in the front-to-back direction, and it is possible to ensure sufficient spacing between adjacent fixed portions 728 and between the pads to which they are soldered.

[0083] As described above, each of the first-type second terminals 710 has two pressing contacts 712, and each of the second-type second terminals 720 has two pressing contacts 722. That is, each of the second terminals 700 has two pressing contacts 712, 722.

[0084] 3, when the first size S1 is the first-class pressed size Sa minus the first-class pressing distance D1, and the second size S2 is the second-class pressed size Sb minus the second-class pressing distance D2, the first size S1 is different from the second size S2. That is, the first size S1 (= Sa - D1) and the second size S2 (= Sb - D2) satisfy S1 ≠ S2.

[0085] As described above, in the assembly 10 of the present embodiment, in the state where the first connector 100 and the second connector 500 are fitted, the pressing contacts 712 and 722 of the second terminal 700 press the corresponding pressed contacts 312 and 322 of the first terminal 300 in the width direction, and the first size S1 and the second size S2 satisfy S1≠S2. Thereby, in the assembly 10 of the present embodiment, when the first connector 100 and the second connector 500 are fitted, the required insertion force is reduced, and the first terminal 300 and the second terminal 700 are in two-point contact to ensure connection reliability. [[ID=‎1]] [[ID=‎2]]

[0086] [[ID=‎3]] [[ID=‎4]]Particularly, in the present embodiment, the second size S2 is smaller than the first size S1. That is, S2 < S1. Thereby, in the assembly 10 of the present embodiment, when the first connector 100 and the second connector 500 are fitted, the force received by the second type first terminal 320 from the second type second terminal 720 is smaller than the force received by the first type first terminal 310 from the first type second terminal 710. That is, in the assembly 10 of the present embodiment, when the first connector 100 and the second connector 500 are fitted, the reduction of the required insertion force is surely achieved. [[ID=‎5]] [[ID=‎6]]

[0087] [[ID=‎7]] [[ID=‎8]]The fixing operation of the second type second terminal 720 to the second holding member 600 will be described in detail below. [[ID=‎9]] [[ID=‎10]]

[0088] [[ID=‎11]] [[ID=‎12]]First, prepare two sets of second terminal row intermediates 800 each composed of a plurality of blanks 820 connected to the carrier 810 via the connecting portions 812, and arrange them as shown in FIG. 21. In this state, the blanks 820 are arranged in two-fold rotational symmetry in a plane orthogonal to the vertical direction. More specifically, in this state, the blanks 820 are arranged in a staggered pattern. Also, in this state, the carriers 810 of the two sets of second terminal row intermediates 800 are located on both sides in the front-rear direction sandwiching the blanks 820. [[ID=‎13]] [[ID=‎14]]

[0089] [[ID=‎15]] 20, 23, and 26, the blank 820 is press-fitted from below into the second holding member 600. Specifically, the held portion 826 of the blank 820 is press-fitted from below into the second holding portion 620 of the second holding member 600. This results in the first intermediate 850 shown in FIGS. 24 to 26.

[0090] 24 and 26, a cutting blade (not shown) is inserted from above the opening 605 to cut the connecting portion 812 between the front carrier 810 and the blank 820. of , and simultaneously divide. Similarly, a cutting blade is inserted from above the opening 605 to simultaneously cut the connecting portion 812 between the rear carrier 810 and the blank 820. 27 and 28 is obtained. As a result, the blank 820 becomes the second-type second terminal 720, and the process of fixing the second-type second terminal 720 to the second holding member 600 is completed. Note that the end of the blank 820, which is generated by cutting the connecting portion 812, becomes the fixed portion 728 of the second-type second terminal 720.

[0091] The second connector 500 of the present embodiment has an opening 605. As a result, in the process of fixing the second-type second terminals 720 to the second holding member 600 in the second connector 500 of the present embodiment, as described above, by inserting a cutting blade into the opening 605, it is possible to collectively separate the front carrier 810 and the blank 820, and also collectively separate the rear carrier 810 and the blank 820. Therefore, the manufacturing process of the second connector 500 of the present embodiment is simplified, and it can be manufactured more inexpensively.
