Abstract
A bulkhead system for passing conductors between a high-pressure side and a low-pressure side. The bulkhead may be used in harsh environments to pass signals or power to sensors and actuators on one side and to sensitive electronics on the other side. The conductors run through and are bonded at sides to a body, which body is supported in the direction of the pressure differential and not highly supported in other directions.
Claims20
A bulkhead operating between a high-pressure side and a low-pressure side comprising:
- a. a solid body having a first side and a second side;
- b. a plurality of conductors hermetically passing through the solid body, with ends of the plurality of conductors extending beyond the first and second sides of the solid body;
- c. a support substrate formed to a) receive the solid body, b) contact the solid body on the first side, and c) pass a first of the ends of the conductors therethrough;
- d. a seal located between the support substrate and the solid body, the seal surrounding the plurality of conductors passing through the support substrate;
- and
- e. a retainer directly or indirectly contacting the second side of the solid body and fixed to the support substrate.
A bulkhead operating between a high-pressure side and a low-pressure side comprising:
- a. a solid body having a first side and a second side;
- b. a plurality of conductors hermetically passing through the solid body, with ends of the plurality of conductors extending beyond the first and second sides of the solid body;
- c. a support substrate formed to a) receive the solid body, b) contact the solid body on the first side, and c) pass a first of the ends of the conductors therethrough, wherein the support substrate has a recess that is wider than a width of the solid body to create a gap around the solid body;
- and
- d. a seal located between the support substrate and the solid body, the seal surrounding the plurality of conductors passing through the support substrate.
A bulkhead operating between a high-pressure side and a low-pressure side comprising:
- a. a solid body having a first side and a second side;
- b. a plurality of conductors hermetically passing through the solid body, with ends of the plurality of conductors extending beyond the first and second sides of the solid body:
- c. a support substrate formed to a) receive the solid body, b) contact the solid body on the first side, and c) pass a first of the ends of the conductors therethrough, wherein the solid body has a coefficient of thermal expansion substantially similar to or within 50% of a coefficient of thermal expansion of the support substrate;
- and
- d. a seal located between the support substrate and the solid body, the seal surrounding the plurality of conductors passing through the support substrate.
