In the fitting detection connector disclosed in Patent Document 2 below, the lock member is made of a metal plate and includes an elastically displaceable main body, and the first movable contact portion is defined by a slit formed in the main body. The second movable contact portion is disposed on the main body portion, the first fitting detection terminal includes a first fixed contact portion that contacts the first movable contact portion, and the second fitting detection terminal contacts the second movable contact portion. When the first connector and the second connector are fitted, the lock member and the locked member are engaged, and the first movable contact portion and the first fixed contact portion are in contact with each other. The second movable contact portion and the second fixed contact portion come into contact with each other, and the first fitting detection terminal and the second fitting detection terminal are brought into conduction through the main body portion.

  With such a configuration, according to the fitting detection connector disclosed in Patent Document 2 below, it is possible to reduce the load for bending the main body portion of the lock member and improve the operability. The fitting between the first connector and the second connector can be detected stably.

  Patent Document 3 below discloses an invention of a connector having a fitting detection function. In the connector disclosed in Patent Document 3 below, the other connector housing is disposed on the front side in the fitting direction with respect to the contact portion of the second detection terminal, and the contact portion of the first detection terminal is being fitted to both connector housings. A slidable contact portion that can be slidably contacted is provided.

  By adopting such a configuration, according to the connector disclosed in Patent Document 3 below, foreign objects are removed from the contact portions in the middle of the fitting of the two connector housings by the sliding contact of the sliding contact portions. This eliminates the need to bother removing foreign matter in the stage before mating, and the contact portion from which the foreign matter has been removed comes in contact with the contact portion of the second detection terminal, ensuring the reliability of the fitting detection function.

A wiping effect can be obtained. By doing in this way, electrical stability becomes higher and fitting detection can be reliably performed by connecting the short terminal 48 and the fitting detection terminal 104 reliably.

  Further, since the short terminal 48 is mounted only on the mounting portion 60 side when it is mounted on the mounting portion 38, the contact portion 55 side at the other end can be slightly varied with the mounting portion 60 as an axis. By doing in this way, when the short terminal 48 and the fitting detection terminal 104 are connected, even if the position of the fitting detection terminal 104 to be inserted is slightly shifted, the contact portion 55 of the short terminal 48 varies, It will be possible to connect smoothly.

  Further, the fitting detection terminals 104 provided on the second housing 77 are arranged side by side with the other second contacts 99 (see FIG. 10). By doing in this way, it is not necessary to have a special structure for providing the fitting detection terminal 104, and the fitting detection terminal 104 can be provided with the same structure as the structure in which the second contact 99 is provided. Become.

  Further, the second lock member 35 is completely engaged with the first housing 12, so that the restricting portion 47 of the second lock mechanism 34 is disposed below the first lock member 30 of the first lock mechanism 29. (See FIG. 19). By doing in this way, even if the press part 33 presses the 1st lock part 31 of the 1st lock mechanism 29 by this control part 47, it is controlled that the 1st lock member 30 moves below, Disengagement between the first lock mechanism 29 and the first engaging portion 91 can be suppressed. That is, the double lock is applied by restricting the movement of the first lock member 30 of the first lock mechanism 29.
