Abstract

A connector comprises a housing extending in a front-rear direction and a sealing member attached in the housing. The housing has a rear wall located at a rear end portion of the housing and an enclosed portion extending from the rear wall in the front-rear direction. When the housing is formed by a molding process, a metal mold is used to form a plurality of seal stoppers around the enclosed portion. Each of the seal stoppers protrudes from the enclosed portion in a direction perpendicular to the front-rear direction. The housing has a plurality of holes which are formed when the metal mold is removed from the housing. Each of the holes pierces the rear wall in the front-rear direction. The holes face the respective seal stoppers in the front-rear direction. The sealing member is attached to the enclosed portion so as to be located between the rear wall and the seal stoppers in the front-rear direction. The front sides of the holes are covered by the sealing member.

Claims

1. A connector comprising:

a housing having a rear wall, a plurality of holes, an enclosed portion, a plurality of seal stoppers and an enclosure, the holes piercing the rear wall in a front-rear direction, the enclosed portion extending forward from the rear wall, the seal stoppers being provided on a periphery of the enclosed portion in a direction perpendicular to the front-rear direction so as to correspond to the holes in the front-rear direction, respectively, the enclosure extending forward from the rear wall while enclosing the enclosed portion and the seal stoppers in a plane perpendicular to the front-rear direction; and

a sealing member attached in the housing, the sealing member being attached to the periphery of the enclosed portion so as to be located between the rear wall and the seal stoppers in the front-rear direction, the sealing member covering the holes.

2. The connector as recited in claim 1, wherein the seal stopper protrudes in a direction perpendicular to the front-rear direction from the periphery of the enclosed portion.

3. The connector as recited in claim 1, wherein:

the rear wall is formed with ditches on a front surface thereof, the ditches being recessed rearward so as to communicate with the holes, respectively; and

a rear end of the sealing member is accommodated in the ditches.

4. The connector as recited in claim 3, wherein the ditches are formed over a full circumference of the periphery of the enclosed portion.

5. The connector as recited in claim 3, wherein the ditch is larger than the hole in a direction perpendicular to the front-rear direction.

6. The connector as recited in claim 1, the connector further comprising a power contact which is held by the housing so as to extend forward, wherein:

the housing is provided with a contact-enclosure which covers the power contact; and

the contact-enclosure protrudes forward beyond the enclosed portion and the enclosure.
