Abstract
The invention relates to a threaded plug on an elongated body for a threaded connection to a threaded bushing, wherein the threaded plug has a conical external thread, in which a section of a flank of the external thread can be represented as a section of a function which has a curvature, wherein the section of the function has an angle to a connecting line of adjacent thread bases or thread tips that is greater than 45° over a height of at least 0.3 times the thread height.
Claims19
A threaded plug on an elongated body for a threaded connection to a threaded bushing, wherein the threaded plug has a conical external thread, in which a section of a flank of the external thread can be represented as a section of a function which has a curvature, wherein the section of the function has an angle to a connecting line of adjacent thread bases or thread tips that is greater than 45°, over a height of at least 0.3 times a thread height,
- wherein the function is a power function having an exponent less than 1 and a base having an exponentiated argument.
A threaded bushing on an elongated body for a threaded connection to a threaded plug, wherein the threaded bushing has a conical internal thread, in which a section of a flank of the internal thread can be represented as a section of a function which has a curvature, wherein the section of the function has an angle to a connecting line of adjacent thread bases or thread tips that is greater than 45°, over a height of at least 0.3 times a thread height,
- wherein the function is a power function having an exponent less than 1 and a base having an exponentiated argument.
A use of a threaded plug or a threaded bushing for a threaded connection to a threaded bushing or a threaded plug, wherein the threaded plug has an external thread or the threaded bushing has an internal thread, in which a section of a flank of the external thread or of the internal thread can be represented as a section of a function which has a curvature, wherein the section of the function has an angle to a connecting line of adjacent thread bases or thread tips that is greater than 45°, over a height of at least 0.3 times a thread height,
- wherein the function is a power function having an exponent less than 1 and a base having an exponentiated argument.
