Environmentally sealed connector with blind mating capability
View Patent ↗A connector assembly ( 10 ) is provided including a first connector ( 12 ) and a second connector ( 14 ) configured to mateably engage the first connector ( 12 ). The first connector ( 12 ) includes a housing ( 16 ), a conductor assembly ( 18 ) positioned within the housing and projecting from housing, and a resilient seal member ( 30 ) enclosing an interface between the housing ( 16 ) and the portion of the conductor assembly projecting from the housing. The second connector ( 14 ) includes an outer contact ( 60 ), an inner contact ( 62 ) nested within a portion of the outer contact ( 60 ), and a housing ( 64 ) containing the inner and outer contacts. Conductors of the conductor assembly ( 18 ) of the first connector ( 12 ) engage the outer ( 60 ) and inner ( 62 ) contacts of the second connector ( 14 ). Another resilient seal member ( 45 ) includes a flexible skirt ( 50 ) formed at an end portion thereof. The flexible skirt ( 50 ) forms a shroud covering a mating interface between a first conductor ( 20 ) of the first connector ( 12 ) and the inner contact ( 62 ) of the second connector ( 14 ) when the first and second connectors are mated. Design features incorporated into the second connector housing ( 64 ), inner contact ( 62 ), and outer contact ( 60 ) act to retard undesirable unmating of the connectors. The connector assembly ( 10 ) of the present invention may be used in applications requiring a dual wire or coaxial connector resistant to adverse environmental conditions, such as exposure to high-pressure gases or liquids, elevated temperatures, vibration, salt spray, etc.
1. A connector comprising:
a conductor assembly including a first conductor, a second conductor spaced apart from the first conductor and enclosing at least a portion of the first conductor, and a first resilient seal member interposed between the first conductor and the second conductor, the first seal member having a plurality of first accordion folds engaging at least a portion of the first conductor to form a corresponding plurality of interference fits with the first conductor, and a plurality of second accordion folds engaging at least a portion of the second conductor to form a corresponding plurality of interference fits with the second conductor.
2. The connector of claim 1 wherein the first seal member is formed from an elastomeric material.
3. The connector of claim 1 wherein the first seal member includes a flexible skirt formed at an end portion thereof, for forming a shroud covering a mating interface between the first conductor and a complementary mating conductor when the first conductor is mated with the mating conductor.
4. The connector of claim 3 wherein a portion of the mating conductor engages a portion of the shroud during attempted unmating of the first conductor from the mating conductor, to impede unmating of the first conductor from the mating conductor.
5. The connector of claim 1 wherein the conductor assembly further includes an insulator positioned exterior of the second conductor and enclosing at least a portion of the second conductor, and wherein the connector further comprises a second resilient seal member including a plurality of lips engaging at least a portion of the second conductor along a surface thereof, to impede migration of contaminants therealong.
6. The connector of claim 5 wherein the second seal member is formed from an elastomeric material.
7. The connector of claim 5 further comprising a first connector housing, and wherein the conductor assembly is secured within the housing and extends from the housing, and the second seal member further includes a plurality of lips engaging the housing along at least one surface thereof to impede migration of contaminants to an interface between the housing and the insulator.
8. The connector of claim 5 further comprising another insulator interposed between the first and second conductors, the other insulator having an end portion abutting the first seal member for positioning the first seal member along the first conductor.
9. The connector of claim 5 wherein a reinforcing member engages the second seal member for structurally reinforcing the second seal member.
10. The connector of claim 9 wherein the reinforcing member is insert-molded within the second seal member.
