At this time, the stopper projection comes into contact with the back side surface of the mounting panel, the inclined surface of the inclined projection engages with the front edge of the mounting hole of the mounting panel, and the mounting panel is sandwiched between the stopper projection and the inclined projection. Is done. At the same time, since the inclined surface of the inclined protrusion is pressed against the front edge of the mounting hole by the stopper spring piece, when the panel mounting connector deviates from a predetermined position, it is returned to the predetermined position by this inclined surface. No rattling occurs. In addition, since the inclined surface of the inclined protrusion is inclined with respect to the front surface and the plate pressure direction of the mounting panel, even if the thickness of the mounting panel is different, the front edge of the mounting hole and the inclined surface are somewhere. Since they are in contact with each other, the mounting panel is securely held between the stopper projection and the inclined projection even if the thickness is different.

Is provided with a tongue-shaped stopper spring piece 7 integrally connected to the insulator 30 on the side of the mounting panel 1 and extending from this portion toward the front surface of the panel mounting connector 3. The stopper spring piece 7 is provided with a stopper projection 71 on its base side and an inclined projection 73 on its free end side.

The front surface of the stopper projection 71 is in contact with the rear side surface of the mounting panel 1, and the rear surface is an inclined surface that is inclined away from the side surface of the insulator 30 toward the free end.

The inclined projection 73 also has an inclined surface 73a. The inclined surface 73a is a surface inclined with respect to the front side surface of the mounting panel 1 and the thickness direction of the mounting panel 1, and the panel mounting connector 3 is mounted. In a state of being attached to the panel 1, the stopper spring piece 7 is pressed against and contacts the front edge of the attachment hole 11.

The above-mentioned stopper spring piece 7, stopper protrusion 71, and inclined protrusion 73 constitute a stopper mechanism.

By the way, as described above, the mounting panel 1
When the panel mounting connector 3 attached to the panel mount 3 vibrates due to vibration or the like, as shown in FIG. 3, the contact position between the inclined surface 73a of the inclined projection 73 and the mounting panel 1 is increased. The mounting panel 1 pushes the stopper spring piece 7 inward,
As a result, a reaction force is generated in the stopper spring piece 7. This reaction force pushes the inclined surface 73a of the inclined protrusion 73 back outward, so that the contact position between the inclined surface 73a and the mounting panel 1 is returned to the original position. In this way, rattling of the panel mounting connector 3 is suppressed.
