Embodiment Construction

[0030] Preferred embodiments of the sealing member installation error preventing structure according to the present invention will be described below with reference to the accompanying drawings.

[0031] figure 1 is a perspective view of a male housing having a sealing member installation error preventing structure according to the present invention.

[0032] In this embodiment, the sealing structure is described as being applied to a connector (connecting portion integrally provided on an included device) used in electric wire wiring.

[0033] The sealing structure is constituted by a male housing 1 and an unillustrated female housing fitted on the male housing 1 . The male housing 1 has a fitting portion 5 constituting a cylindrical member provided on the device connecting portion 3 so as to protrude therefrom. A pair of male terminals 7a, 7b are provided inside the fitting portion 5 so as to protrude for electrical connection with female terminals provided inside the fem...

Abstract

A sealing unit with a mounting error preventing construction, includes a cylindrical member and an annular sealing member mounted in a circumferential groove formed on an outer circumference of the cylindrical member. At least two projections having different sizes are provided on the sealing member asymmetrically with respect to an axis of the sealing member and are projected in a direction in which the axis extends. Cutout portions for receiving the projections are provided on the cylindrical member.

Description

technical field [0001] The present invention relates to a sealing unit having an installation error prevention structure realized by installing an annular sealing member in a circumferential groove formed on the outer circumference of a cylindrical member. Background technique [0002] A connector for connecting electric wires or optical fibers together has a waterproof and airtight structure, so as to prevent infiltration of water and dust, which is realized by sealing a space between two connecting parts with a sealing member (refer to, for example, , Patent Document 1). In general, in a connector with a waterproof structure or an airtight structure, the connecting portion of the housing constituting the sealing structure is formed in a cylindrical shape, and in it are two cylindrical shapes of a male housing and a female housing. In the connecting portion, the male housing is inserted into the inner circumference of the female housing for connection. The sealing member ...
