Abstract
In the context of downhole tools, bulkhead igniter assemblies having snap-on insulators are disclosed. In some embodiments the bulkhead igniter assemblies have a bulkhead with a first end formed with at least one ridge or groove, a pressure block, a setting tool, and a snap-on insulator. The snap-on insulator has an annular body having a tubular channel through a center portion. Ridges or groves on the snap-on insulator mate with ridges or grooves on the bulkhead igniter to hold the snap-on insulator in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter. Other embodiments are disclosed.
Claims18
A bulkhead igniter assembly comprising:
- a bulkhead igniter having a first end and a second end, wherein the first end of the bulkhead igniter is formed with at least one ridge or groove on an annular protrusion;
- a pressure block having a first end and a second end, wherein the bulkhead igniter is disposed within a cavity of the pressure block;
- a setting tool having a first end and a second end, wherein the pressure block is at least partially disposed within a cavity of the setting tool located proximate to the first end of the setting tool;
- and
- a snap-on insulator, wherein the snap-on insulator comprises:
- an annular body having a tubular channel through a center portion,
- wherein, the snap-on insulator has a first end and a second end,
- wherein, an interior of the tubular channel is formed with a ridge or a groove that is sized and configured to be a complimentary member to the ridge or groove on the first end of the bulkhead igniter, whereby the snap-on insulator is held in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter,
- wherein, the snap-on insulator is formed from a material that allows for enough flexibility for a ridge-and-groove coupling to occur so that the snap-on insulator may be installed onto the bulkhead igniter by pressing the snap-on insulator onto the bulkhead igniter to engage the ridge or groove of the snap-on insulator with the ridge or groove of the first end of the bulkhead igniter;
- and
- wherein, the snap-on insulator is formed from a material that will not conduct electricity.
A bulkhead igniter assembly comprising:
- a bulkhead igniter having a first end and a second end, wherein the first end of the bulkhead igniter is formed with at least one ridge or groove;
- a pressure block having a first end and a second end, wherein the bulkhead igniter is disposed within a cavity of the pressure block;
- and
- a snap-on insulator, attached to the first end of the bulkhead igniter, wherein, the snap-on insulator comprises:
- an annular body having a tubular channel through a center portion,
- wherein, the snap-on insulator has a first end and a second end,
- wherein, an interior of the tubular channel is formed with a ridge or a groove that is sized and configured to mate in a complementary manner to the ridge or groove on the first end of the bulkhead igniter, whereby the snap-on insulator is held in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter;
- and
- wherein, the snap-on insulator is formed from a material that allows for enough flexibility for a ridge-and-groove coupling to occur so that the snap-on insulator may be installed onto the bulkhead igniter by pressing the snap-on insulator onto the bulkhead igniter to engage the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter, and wherein, the snap-on insulator is formed from a material that will not conduct electricity.
