Abstract

One example includes a signal connector system. The system includes a first connector comprising a first housing and first contacts formed from a self-passivating transition metal and configured to conduct an AC signal. The system also includes a second connector comprising a second housing and second contacts formed from the self-passivating transition metal and configured to electrically couple to a respective one of the first contacts to conduct the AC signal. The first and second housings can be coupled to enclose the signal connector and to create at least one fluid-filled channel between each of the electrically-connected first and second contact pairs in response to fastening the first and second connectors while submerged in a respective fluid to provide a resistive path in the at least one fluid-filled channel for providing signal isolation between each of the electrically-connected first and second contact pairs.

First claim

1. A signal connector system comprising:
a first connector comprising a first housing and a first plurality of contacts formed from a self-passivating transition metal, each of the first contacts being configured to conduct an alternating current (AC) signal; and
a second connector comprising a second housing and a second plurality of contacts formed from the self-passivating transition metal, each of the second contacts being configured to electrically couple to a respective one of the first contacts to conduct the AC signal, the first and second housings being configured to be coupled to substantially enclose the signal connector and to create at least one fluid-filled channel between each of the electrically-connected first and second contact pairs in response to fastening the first and second connectors while submerged in a respective fluid to provide a resistive path in the at least one fluid-filled channel for providing signal isolation between each of the electrically-connected first and second contact pairs.

2. The system of claim 1 , wherein the first connector further comprises a first plurality of pliable insulator supports that are coupled to a respective one of the first contacts, wherein the second connector further comprises a second plurality of pliable insulator supports that are each coupled to a respective one of the second plurality of contacts, each of the first and second pliable insulator supports is configured to provide contact pressure between the respective first contacts and the respective second contacts to establish electrical connection between the respective first and second contacts.

3. The system of claim 2 , wherein the first pliable insulator supports and the second pliable insulator supports are coupled to the respective first contacts and the respective second contacts along a first longitudinal surface, wherein each of the first and second pliable insulator supports comprises a second longitudinal surface opposite the first surface, wherein the second longitudinal surface of each of the first pliable insulator supports and the second longitudinal surface each of the respective second pliable insulator supports defines at least a portion of a respective one of the at least one fluid-filled channel.

4. The system of claim 2 , wherein each of the first and second pliable insulator supports has a predetermined elasticity sufficient to substantially mitigate galling between the first and second contacts.

5. The system of claim 1 , wherein each of the first contacts comprises a tapered contact surface that is arranged to provide electrical connection with a complementary tapered contact surface of a respective one of the second contacts.

6. The system of claim 5 , wherein each of one of the first and second contacts comprises a projection extending from the respective tapered contact surface to provide the electrical connection with the tapered surface of the respective other of the first and second contacts.

7. The system of claim 1 , wherein the first and second contacts are arranged in a polar array about the respective first and second connectors, such that the at least one fluid-filled channel is disposed between each electrically-connected first and second contact pair about the polar array.

8. The system of claim 1 , wherein the first housing comprises a male thread pattern and the second housing comprises a female thread pattern, such that each electrically-connected set of the first and second contacts can have an approximately equal contact pressure when the first and second connectors are coupled together to form the signal connector system.

9. The system of claim 1 , wherein each of the at least one fluid-filled channel has a geometrical arrangement designed to provide a resistance of the respective resistive path of greater than or equal to approximately 100Ω when filled with the associated fluid.

10. A method for providing a plurality of alternating current (AC) signals along a respective plurality of conductors across a signal connector system, the method comprising:
submerging a first connector and a second connector in a fluid, the first connector comprising a first housing and a first plurality of contacts formed from a self-passivating transition metal, the second connector comprising a second housing and a respective second plurality of contacts formed from the self-passivating transition metal, such that a dielectric film forms on the first and second contacts in response to submersion in the fluid;
