DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mounting structure for mounting a connector to a unit via a gasket, and more particularly to a structure for ensuring high sealing between the connector and the unit.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 4, the flange 41 of the connector 40 abuts on the periphery of the opening 43 of the unit 42 via the gasket 44, and the male connector 45 of the connector 40.
Is loosely fitted into the opening 43 of the unit 42, and in this state, the connector 40 is fixed to the unit 42 by a plurality of (four in FIG. 3) male screws 46.

In the vicinity of the four corners of the flange 41 of the connector 40, substantially cylindrical female screw members 47 are insert-molded. Inside each female screw member 47, a through hole 48 is formed along the longitudinal direction,
Each through hole 48 communicates with a through hole 49 of the unit 42 and a through hole 50 of the gasket 44, respectively. A female screw 51 to which the male screw 46 can be screwed is formed on the inner surface of each through hole 48. The male screw 46 is screwed into the female screw 51 of each female screw member 47 from the side opposite to the connector 40 with the unit 42 interposed therebetween, through the through hole 49 of the unit 42 and the through hole 50 of the gasket 44.
Thereby, each of the male screws 46 fixes the connector 40 to the unit 42 via the gasket 44.

[0004]

4, the sealing property between the connector 40 and the unit 42 is ensured. However, the connector 40 does not have a structure in which the connector 42 comes into contact with the unit 42, and in a state where the male screw 46 is screwed into the female screw 51 of the female screw member 47, the repulsive force accompanying the tightening of the male screw 46 is It acts directly on the flange 41 of 40. For this reason, there has been a problem that the flange 41 is deformed such as a warp or the female screw member 47 falls off the flange 41. Therefore, it was extremely difficult to ensure high sealing between the connector 40 and the unit 42.

According to the present invention, for example, deformation of the flange due to excessive tightening of the male screw or dropping of the female screw from the flange can be reliably prevented, thereby stably maintaining a high sealing property between the connector and the unit. It is an object to provide a connector mounting structure that can be secured.
