Next, when the male connector a is moved in the second direction, that is, the arrow direction, the protrusion d is guided by the inclined groove portion f of the fixed frame body c and moves toward the back, and the male connector a becomes the female connector b. Then, the grommet k is fixed with a bolt and a metal fitting m.

In this case, the grommet k can be bolted even if the pulling-in of the male connector a is insufficient, so that a contact failure of the built-in terminal fitting occurs (Fig. 7b).

[Problems to be solved by the device]

The present invention has been made by paying attention to the above-mentioned points, and when the mating of the pair of connectors facing each other is insufficient, it is impossible to attach the grommet to the mating side connector at a predetermined position. In this way, a sufficient fitting of the connector is ensured.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the present invention, in a structure in which a pair of connectors are coupled inside the fixing frame fixed to the through hole and penetrating in the through hole direction of the fixing frame, the fixing frame is penetrated. On one side of the inner wall forming the inside, a connector guide support groove is formed following the introduction groove in a direction orthogonal to the fitting direction of the connector, and on the other side of the inner wall, the introduction direction is followed by the fitting direction of the connector. A diagonally intersecting connector guide support groove is formed to couple a pair of connectors facing each other through the pair of connector guide support grooves, and a grommet for the connector guided in the oblique connector guide support groove is formed. A structure is adopted in which the fixing metal fitting can be fixed at a predetermined position when the connector is completely fitted.
