On a front end surface (15) of a male housing (10), a columnar sealing projection (17) is formed for a projected portion of each of the male terminals (16). On a front end surface (21) of a female housing (20), low ribs (35) are formed in the shape of a lattice in such a way that the ribs (35) surround a front opening of each cavity (22). A sealing member (50) having through-holes (51) formed thereon is formed integrally with a rear surface of a front plate (41) of a holder (40) by two-color molding. When the holder (40) is mounted on the female housing (20), a contact surface (54) of the sealing member (50) is pressed against the front end surface (21) of the female housing (20). When the female housing (20) is connected to the male housing (10), the inner peripheral surfaces of the through-holes (51) of the sealing member (50) closely contact the peripheral surfaces of the sealing projections (17) with the sealing projections (17) breaking the lips (52) of the sealing members (50). In the female housing (20), the contact surface (54) of the sealing member (50) is pressed against the front end surface (21) of the female housing (20), with the ribs (35) of the front end surface (21) cutting into the contact surface (54). In this way, waterproofing of the housing chambers is accomplished.

1. Field of the Invention
The present invention relates to a waterproof connector.
2. Description of the Related Art
FIG. 1 is a side sectional view showing a state before a male housing and a female housing of a connector are fitted together according to an embodiment of the present invention.
FIG. 2 is a front view showing the male housing.
FIG. 3 is a side sectional view showing a state before a holder is mounted on the female housing.
An embodiment of the present invention is described below with reference to FIGS. 1 through 10.
As shown in FIG. 1, the waterproof connector of the illustrated embodiment has a male housing 10, a female housing 20, and a sealing member 50 to be mounted on the female housing 20. In the description below, the sides of the male housing 10 and of the female housing 20 that connect to the opposing housing are each considered as the front or forward side.
The male housing 10 is preferably of a substrate-installed type and made of a synthetic resinous material. A hood part 12 projects from a front surface of a body plate 11. A mounting plate 13 for a printed-circuit board P is formed at a lower portion of a rear surface of the body plate 11. The front surface of the body plate 11 serves as a front end surface 15 of the male housing 10.
