Embodiment Construction

[0031] The following will refer to Figure 1 to 1 0 illustrates an embodiment of the present invention.

[0032] Such as figure 1 As shown, the waterproof connector of the illustrated embodiment has a male housing 10 , a female housing 20 , and a seal 50 to be mounted on the female housing 20 . In the following description, the side where each of the male housing 10 and the female housing 20 is connected to the opposite housing is referred to as a front side.

[0033] The male housing 10 is preferably a substrate mount type and made of a synthetic resin material. The cover portion 12 protrudes from the front surface of the main body panel 11 . A mounting board 13 for a printed circuit board P is formed at a lower portion of the rear surface of the main body board 11 . The front surface of the main body plate 11 serves as the front end surface of the male housing 10 .

[0034] The L-shaped terminal male fitting 16 is fitted within the male housing 10 by insert molding. Su...

Abstract

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.

Description

technical field [0001] The invention relates to a waterproof connector. Background technique [0002] A waterproof connector is disclosed in Japanese Patent Application No. 2002-267000, in which a cavity accommodating a terminal is sealed. Such a waterproof connector will be described below with reference to FIG. 11 . The waterproof connector has a female housing 1 which is provided with a plurality of cavities 1A for accommodating terminal female connectors 2 . The male housing 3 is designed for a printed circuit board and includes a cover portion 3A in which the female housing 1 can be fitted. The L-shaped terminal male fitting 4 protrudes from the front end surface into the cover portion 3A. A fitting recess 5 is formed around the protrusion of the terminal male fitting 4 on the cover portion 3A of the male housing 3 . The seal 6 is fitted in the fitting recess 5 . [0003] A press-fit groove 7 is formed around the opening 6A on the surface of the seal 6 . On the fr...
