The rigid body contact portion 62 of each second solder peg 60 slightly protrudes in the front-rear direction from the second solder peg attachment portion 45 of the second housing 41, as shown in FIGS. As shown in FIG. 1B, each of the second solder pegs 60 has a pair of first solder peg members 30A with the

rigid contact portions

62 and 62 when the plug connector 40 is fitted to the receptacle connector 10. , 30B are fitted and contacted between the

elastic arms

34, 34. Here, the two sets of the first solder peg 30 and the second solder peg 60 constitute a fitting completion detection switch S for the plug connector 40 and the receptacle connector 10 that are fitted to each other.

Next, a method for fitting the plug connector 40 to the receptacle connector 10 will be described.
First, the receptacle connector 10 is fixed on one circuit board PCB1 and the plug connector 40 is fixed on the other circuit board PCB2 by soldering.
1A and 1B, the contact support wall 43 of the plug connector 40 is placed in the mating connector receiving recess 14 of the receptacle connector 10, and the second solder peg mounting portion 45 of the plug connector 40 is received as the receptacle. The connector 10 is inserted into the solder peg receiving recess 17.

Then, first, the contact part 52 of the second contact 50 provided in the plug connector 40 contacts the contact part 22 of the first contact 20 provided in the receptacle connector 10 at the contact point P1. Thereby, one circuit board PCB1 and the other circuit board PCB2 are electrically connected via the first contact 20 and the second contact 50.

Then, when the insertion of the plug connector 40 is promoted, the rigid contact portion 62 of the second solder peg 60 of the plug connector 40 is then contacted between the

elastic arms

34, 34 of the pair of first

solder peg members

30A, 30B. The fitting contact is made at P2. Thus, after the first contact 20 and the second contact 50 are in contact, the first solder peg 30 and the second solder peg 60 are in contact because the height of the contact point P1 from the circuit board PCB1 is H1. This is because the height of the contact point P2 from the circuit board PCB1 is set to H2, and the height H1 is set to be larger than the height H2.

Then, when the insertion of the plug connector 40 is promoted, the fitting completion state shown in FIGS. 1A and 1B is reached.
Here, the rigid contact portion 62 of the second solder peg 60 of the plug connector 40 is fitted and brought into contact between the

elastic arms

34, 34 of the pair of first

solder peg members

30A, 30B at the contact point P2. The fitting detection circuit forms a closed circuit, and the completion of fitting between the plug connector 40 and the receptacle connector 10 can be detected.

As described above, according to the present embodiment, the first solder peg 30 and the second solder peg 60 detect the fitting completion detection switch that detects the fitting completion state between the plug connector 40 and the receptacle connector 10 that are fitted to each other. S is constructed. In the fitting completion detection switch S, the first solder peg and the 30 second solder peg 60 come into contact after the first contact 20 and the second contact 50 come into contact with each other when the pair of connectors are fitted together. Is configured to do. Therefore, the first contact 20 for transmitting signals before the first solder peg 30 and the second solder peg 60 constituting the fitting completion detection switch S come into contact with each other and the fitting detection circuit forms a closed circuit. And the second contacts 50 are always in contact with each other, and then, when the fitting is completed, the first solder peg 30 and the second solder peg 60 come into contact to form a closed circuit. As a result, it is possible to detect the fitting completion state of the plug connector 40 and the receptacle connector 10 that are fitted to each other using the contact between the first solder peg 30 and the second solder peg 60. Further, even after the plug connector 40 and the receptacle connector 10 are completely fitted, the contact state between the first solder peg 30 and the second solder peg 60 is maintained. It is possible to detect reliably after the completion of the fitting.

Each pair of first solder pegs 30 includes a pair of first

solder peg members

30A and 30B provided at one end in the longitudinal direction of the first housing 11 so as to be separated from each other. When the plug connector 40 and the receptacle connector 10 are fitted, 60 is fitted and brought into contact between the pair of first

solder peg members

30A and 30B. Therefore, the fitting detection signal flows in the order of one of the pair of first

solder peg members

30A and 30B, the second solder peg 60, and the other of the pair of first

solder peg members

30A and 30B. Can be formed by only one circuit board PCB1 on which the first solder pegs 30A and 30B are mounted. Therefore, there is no need to perform wiring or the like on the other circuit board PCB2 in order to form the fitting detection circuit. On the other hand, when the first solder peg 30 is formed of one member and the second solder peg 60 constitutes a fitting completion detection switch, the fitting detection circuit has one circuit board PCB1 and the other circuit board PCB2. It straddles both sides. Thereby, wiring for forming a fitting detection circuit on both circuit boards 1 and 2 is required.

Further, a pair of first

solder peg members

30A and 30B are installed at both longitudinal ends of the first housing 11, and a second solder peg 60 is installed at both longitudinal ends of the second housing 41. Therefore, when the pair of first

solder peg members

30A, 30B constituting the fitting completion detection switch S at both ends in the longitudinal direction and the second solder peg 60 come into contact with each other, it can be determined that the fitting is completed. Accordingly, the pair of first

solder peg members

30A and 30B and the second solder peg 60 constituting the fitting completion detection switch S only at one end in the longitudinal direction are in contact with each other and the pair of first solder pegs at the opposite end. When the

members

30A and 30B do not contact the second solder peg 60, the fitting is incomplete. For this reason, when the plug connector 40 and the receptacle connector 10 are fitted, for example, one connector 40 (10) is relatively inclined in the longitudinal direction to constitute a fitting completion detection switch S only at one end in the longitudinal direction. When the pair of first

solder peg members
