Harsh environment connector including single-level or dual-level bladder and associated methods
A connector, such as for harsh environments, may include first and second connector portions being movable between unmated and mated positions. The first connector portion may include a first base, a male contact carried by the first base and extending outwardly therefrom, and a first shell carried by the first base and surrounding the male contact. The second connector portion may include a second base, and a female contact carried by the second base and extending outwardly therefrom. The second connector portion may further include a single-level bladder carried by the second base and defining only a single-level bladder chamber surrounding the female contact, and a second shell carried by the second base and surrounding the single-level bladder. A dual-level bladder connector embodiment may include an end cap defining a seal to end portions of the inner bladder opposite the second base, and an outer bladder surrounding the inner bladder. The outer bladder may define a first seal with the inner bladder adjacent the base and may define a second seal with the end cap.

5. The connector according to claim 1 wherein each female contact comprises a guide tube, a moveable stopper received in an end of said guide tube, and a spring urging said stopper toward the end of said guide tube.
6. The connector according to claim 1 further comprising a dielectric material contained within each chamber of said single-level bladder.
7. The connector according to claim 1 wherein at least one of said male contacts comprises an electrically conductive member and a dielectric layer surrounding a portion thereof to define an electrically conductive tip.
8. The connector according to claim 1 , further comprising an end cap having a plurality of passageways each aligned with a respective female contact, the single-level bladder having a plurality of end seal portions opposite said second base, each end seal portion communicating with a respective single level bladder chamber and extending into a respective aligned end cap passageway, and each end seal portion surrounding an end portion of the respective female contact.
9. A connector comprising:
first and second connector portions movable between unmated and mated positions;
said first connector portion comprising a first base, a plurality of male contacts carried by said first base and extending outwardly therefrom, and a first shell carried by said first base and surrounding said male contacts;
said second connector portion comprising a second base, a plurality of female contacts carried by said second base and extending outwardly therefrom, a single-level bladder carried by said second base and defining only a single-level bladder chamber surrounding said female contacts, and a second shell carried by said second base and surrounding said single-level bladder;
said single-level bladder comprising an outer wall and at least one wall partition therein integrally formed as a monolithic unit and defining a respective single-level bladder chamber for each of said female contacts; and
a dielectric material contained within said single-level bladder.
10. The connector according to claim 9 further comprising an end cap surrounding said single-level bladder at end portions thereof opposite said second base.
11. The connector according to claim 9 further comprising a plurality of nipples extending inwardly from said second base and aligned with respective ones of said plurality of female contacts; and wherein said single-level bladder comprises end portions defining respective constrictive seals with said plurality of nipples.
12. The connector according to claim 9 wherein said female contacts each comprises a guide tube, a moveable stopper received in an end of said guide tube, and a spring urging said stopper toward the end of said guide tube.
13. The connector according to claim 9 wherein said male contacts each comprises an electrically conductive member and a dielectric layer surrounding a portion thereof to define an electrically conductive tip.
14. The connector according to claim 9 , further comprising an end cap having a plurality of passageways each aligned with a respective female contact, and the single-level bladder having a plurality of end seal portions opposite the second base and integrally formed with the bladder, each end seal portion communicating with a respective single level bladder chamber and extending into a respective aligned end cap passageway, each end seal portion surrounding an end portion of the respective female contact.
15. A method for making a connector comprising first and second connector portions to be movable between unmated and mated positions, the method comprising: forming the first connector portion to comprise a first base, a plurality of male contacts carried by the first base and extending outwardly therefrom, and a first shell carried by the first base and surrounding the male contacts; and forming the second connector portion to comprise a second base, a plurality of second contacts carried by the second base and extending outwardly therefrom, a single-level bladder carried by the second base and comprising an outer wall and at least one wall partition therein defining a respective single-level bladder chamber for each of the female contacts, and a second shell carried by the second base and surrounding the single-level bladder.
16. The method according to claim 15 wherein the outer wall and the at least one wall partition are integrally formed as a monolithic unit.
17. The method according to claim 15 further comprising forming at a plurality of nipples extending inwardly from the second base each aligned with a respective one of said female contacts; and wherein the single-level bladder comprises end portions defining constrictive seals with the respective nipples.
18. The method according to claim 15 further comprising forming an end cap surrounding the single-level bladder at end portions thereof opposite the second base.
19. The method according to claim 15 wherein each female contact comprises a guide tube, a moveable stopper received in an end of the guide tube, and a spring urging the stopper toward the end of the guide tube.
20. The method according to claim 15 wherein each of said male contacts comprises an electrically conductive member and a dielectric layer surrounding a portion thereof to define an electrically conductive tip.
