Abstract

<P>PROBLEM TO BE SOLVED: To provide a loosely fitting connector reducing the number of part items, and easy in attachment-detachment to an installing panel. <P>SOLUTION: One connector 1 of the loosely fitting connector composed of a pair of connectors has a flange part 2 having a shape opposable to the installing panel 3. The flange part 2 forms a bush 4 composed of a body part 4a installed on the installing panel 3 and a plate-like slipping-out preventive part 4b having an outer diameter larger than an outer diameter of this body part 4a, and a bush installing hole 5 composed of a hole having an inner diameter larger than an external shape of the body part 4a of the bush 4 and smaller than the outer diameter of the slipping-out preventive part 4b. The bush 4 and the bush installing hole 5 are formed of a resin mold in a mutually integrally joined state via a hinge part 7 formed as to become oblique in the shaft direction of the bush 4. Since the connector 1 can move in a loosely fittable range with the bush installing hole 5 joined via the hinge part 7 to the bush 4 installed on and fixed to the installing panel 3, even when a fitting error is caused when fitting to the other connector (unillustrated) for constituting the loosely fitting connector, the error is properly absorbed. <P>COPYRIGHT: (C)2003,JPO

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a partially sectional view showing an enlarged view of a mounting portion of a loose fitting connector according to an embodiment of the present invention to a mounting member. As shown in FIG. 1, one of the connectors 1, which is a loosely-fitting connector including a pair of matable connectors, has a flange portion 2 having a shape capable of facing a mounting panel 3 which is a mounting member. On the flange portion 2, a main body portion 4a is attached and fixed so that one end is in contact with the attachment panel 3, and a plate-like retaining portion 4b having an outer diameter larger than the outer diameter of the main body portion 4a. And a bush mounting hole 5 formed of a hole having an inner diameter larger than the outer diameter of the main body portion 4a of the bush 4 and smaller than the outer diameter of the retaining portion 4b. In the bush 4, a through hole 6 is formed along the axial direction of the main body portion 4a so as to penetrate the main body portion 4a from the side of the retaining portion 4b and into which the general-purpose screw 10 is inserted. The bush 4 and the bush mounting hole 5 are hinge portions 7 formed so as to be oblique with respect to the axial direction of the bush 4 in a state where the main body portion 4a of the bush 4 is loosely fitted in the bush mounting hole 5. A part of the outer wall of the main body portion 4a and a part of the inner wall of the bush mounting hole 5 are connected to each other via, and they are integrally formed with each other. The flange portion 2 is made of, for example, a resin molded member, and has a bush 4 and a bush mounting hole 5
