The connector 1 is attached to a mounting base 2, which is a back cover made of synthetic resin, which will be described later.

In this embodiment, the mounting base 2 is a back cover molded from synthetic resin, and this back cover is attached to the back surface of the housing.

The mounting base 2 has a recess formed in a part thereof, and a support portion 21.22 for mounting and supporting the pair of mounting wings 16, 17 of the connector 1 is formed in this recess.

The one support part 21 is connected to the one mounting wing 16.
An abbreviated fitting hole 25 is formed from the base 23 to the side wall 24 so that the fitting can be slid in from the side.
Further, a protrusion 26 that is fitted into the through hole 18 formed in the mounting wing 16 when the one mounting wing 16 is slid into the fitting hole 25 is provided to hang down and protrude from the side wall 24. ing.

The height t of the fitting hole 25 formed in the side wall 24 is
The plate thickness is set to be approximately equal to the plate thickness of the mounting wing 16.

The other support part 22 rises from the base 23 and when the other mounting wing 17 is pressed from above, the mounting wing 17
In order to elastically clamp both sides of the mounting wing 17 and prevent the mounting wing 17 from coming off upward, it is composed of a clamping piece 27 having a hook-shaped engagement part at the upper end and a pair of clamping pieces 28. There is.

Since the connector mounting device of the present invention has the above configuration, when the connector 1 is mounted on the mounting base 2, the tip of one of the mounting wings 16 of the pair of mounting wings 16 and 17 of the connector is attached to the mounting base 2. Insert it into the L-shaped fitting hole 25 of one of the supporting parts 21 by sliding it diagonally as shown by arrow A in FIG. 4A.

The mounting wing 16 is inserted into the fitting hole 25 and the side wall 24
When the connector 1 is released from the connector when the protrusion 26 aligned with the through hole 18 of the mounting wing 16, the connector 1 tries to return to the horizontal direction due to its own weight, and the protrusion 26 is fitted into the through hole 18.

In this state, when the other mounting wing 17 is next pressed in the direction of arrow B, the clamping piece 27 which mainly has a hook-shaped engagement part
is deflected outward due to the contact of the mounting wing 17 and clamps the mounting wing 17 between the clamping pieces 27 and 28, and when the mounting wing 17 is retracted to a position below the hook-shaped engagement portion, a hook-shaped engagement occurs. The clamping piece 27 having a section returns to its original position, and the hook-shaped engaging part comes into contact with the upper surface of the mounting wing 17, so that both side edges of the mounting wing 17 are elastically clamped between the clamping pieces 27 and 28.
