A method of correcting the mismatch in the translation direction between the male fastener member and the female fastener member

摘要

A method of correcting translational misalignment between a male fastener element 10 and an arm fastener element 30 to prevent erroneous screw engagement is disclosed as a method for correcting translational misalignment between a male fastener element 10 and an arm fastener element 30, And at least one leading male thread 17 of the male fastener element 10 is inserted into a groove 32 in a ridge of at least one leading female thread 31 of the female fastener element 30. [ Wherein the arm fastener member (30) comprises a plurality of fastener elements (10, 30), each of the fastener elements (10, 30) And at least one leading female screw (31) formed in the inside of the arm fastener member (30) and having a groove (32) in the ridge, wherein the male fastener member (10) The inside of the arm fastener member 30 Shank having a leading end for insertion into keubu; At least one male threaded screw formed on the exterior of the shank portion as a plurality of screw windings configured to mate with the at least one arm tightening screw; And at least one half-winding around the shank portion, formed on the outside of the shank portion at the leading end (14), and being in contact with both flanks of the threaded shape of the at least one male thread- And at least one leading male thread (17) comprising a curved shape defined by a arc having a radius approximately equal to the radius of the arc below the pitch line of the thread.
