Abstract
A male housing (30) has a tubular part (32) with inner and outer tubes (36, 37) separated by a groove (38). A female housing (10) has a fit-in portion (14) to be fit in the inner tube (36). A seal ring (18) is mounted on the fit-in portion (14) and is compressed between opposed surfaces of the fit-in portion (14) and the outer tube (37). Loosening prevention portions (19) on the fit-in portion (14) fill a gap between the opposed surfaces of the fit-in portion (14) and the inner tube (36) and prevent both housings (10, 30) from being radially loosened.
Claims18
A connector comprising:
- a first housing having a tubular part with inner and outer tubes and a groove therebetween;
- a second housing having a fit-in portion to be fit in the tubular part;
- a seal ring compressed between opposed surfaces of the outer tube and the fit-in portion to seal a gap between the first and second housings;
- and
- loosening prevention portions formed integrally with one of the inner tube and the fit-in portion to fill a gap between said opposed surfaces of the inner tube and the fit-in portion and preventing the first and second housings from being loosened radially.

A connector comprising:
- a first housing having a tubular part;
- a second housing having opposite front and rear ends spaced longitudinally from one another, a fit-in portion substantially adjacent the front end of the second housing and configured to be fit in said tubular part, the fit-in portion having at least one curved surface and at least one flat surface spaced longitudinally from the curved surface;
- a seal ring mounted on the curved surface of said fit-in portion and compressed between said curved surface of said fit-in portion and an opposed surface of said tubular part to seal a gap between said first and second housing;
- and
- loosening prevention portions formed integrally on the flat surface of the fit-in portion, which is mounted on a surface of said fit-in portion opposed to said tubular part, said loosening prevention portions being dimensioned to contact an opposed surface of said tubular part for preventing said first and second housings from being radially loosened.
