Abstract
A waterproof connector consists of a female housing 2 and a male housing 3 which are to be coupled with other. The male housing 3 includes a body 15 accommodating female terminals, a cover 15 and a packing 39. The cover 23 includes a plurality of peripheral walls 24 and a wall 50. The wall 50 has a recess 52. A protrusion 53a is provided at the inner edge of the recess 52 close to a packing 39. The protrusion 53a protrudes from the inner edge of the recess 52 close to the packing 39 toward the female housing. The protrusion 53a is arranged between the recess 52 and packing 39. The one end 39a of the packing 39 is located between the protrusion 53a and the body 15. In this configuration, the waterproof connector can prevent water from permeating into a contact portion between terminal metal fittings.
Claims6
A water-proof connector composed of a connector housing and a tube-like complementary connector housing which are coupled with each other, wherein said connector housing comprises:
- a tube;
- a body accommodated in said tube and incorporating a terminal fitting;
- a seal attached to an outer face of said body, which keeps watertight a space between an outer face of the body and an inner face of said complementary connector housing;
- a first protrusion;
- a second protrusion;
- and
- a third protrusion, wherein
- said first, second, and third protrusions are spaced apart from each other, wherein
- said connector housing forms a first through-hole, a second through-hole, and a recess, wherein
- said first through-hole, second through-hole, and recess are spaced apart from each other, wherein
- said first through-hole communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said second through-hole communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said recess communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said first protrusion protrudes from an inner edge of said first through-hole close to said seal toward said complementary connector housing and located between said first through-hole and said seal, wherein
- said second protrusion protrudes from an inner edge of said second through-hole close to said seal toward said complementary connector housing and located between said second through-hole and said seal, wherein
- said third protrusion protrudes from an inner edge of said recess close to said seal toward said complementary connector housing and located between said recess and said seal.
A connector housing for a water-proof connector to be coupled with a tube-like complementary connector housing, wherein said connector housing comprises:
- a tube;
- a body accommodated in said tube and incorporating a terminal fitting;
- a seal attached to an outer face of said body, which keeps watertight a space between an outer face of the body and an inner face of said complementary connector housing;
- a first protrusion;
- a second protrusion;
- and
- a third protrusion, wherein
- said first, second, and third protrusions are spaced apart from each other, wherein
- said connector housing forms a first through-hole, a second through-hole, and a recess, wherein
- said first through-hole, second through-hole, and recess are spaced apart from each other, wherein
- said first through-hole communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said second through-hole communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said recess communicates a space outside said body and inside said tube with an outside of said tube and passing through said tube, wherein
- said first protrusion protrudes from an inner edge of said first through-hole close to said seal toward said complementary connector housing and located between said first through-hole and said seal, wherein
- said second protrusion protrudes from an inner edge of said second through-hole close to said seal toward said complementary connector housing and located between said second through-hole and said seal, wherein
- said third protrusion protrudes from an inner edge of said recess close to said seal toward said complementary connector housing and located between said recess and said seal.
