<p>#CMT# #/CMT# The device has an elongated plate (60) immobilizing clinch nuts (10, 70) in rotation and independent of the nuts. The plate has an inner indentation (66) cooperating with an outer indentation (28) of the nut (10), to immobilize the rotation of the nut (10) relative to the plate. The plate has an orifice (64) that cooperates with the nut (70), where the orifice has inner sides (74) separated by a distance greater than distance between plane sides (72) of the nut (70). The plate and nuts are immobilized in rotation, when the nuts (10, 70) are mounted in orifices (62, 64) respectively. #CMT# : #/CMT# An independent claim is also included for a clinch nut. #CMT#USE : #/CMT# Used for immobilizing the rotation of a clinch nut mounted in an orifice of a piece e.g. annular flange, of a stator in a turbo machine e.g. jet engine or jet prop engine, of an airplane (all claimed), in aeronautical industry. #CMT#ADVANTAGE : #/CMT# The elongated plate is independent of the nuts, thus permitting to transmit screwing efforts of a screw to another clinch nut and the orifice on which the nut is mounted and hence supporting the efforts without problems. The plate therefore facilitates manufacturing of the plate and the clinch nut in a simple, effective and economical manner. The device can be adapted to any type of clinch nut, by varying the dimensions and the shape of the plate and characteristics of the part equipped with the nuts, thus permitting to utilize the nut in a simple and easy manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a clinch nut`s rotation immobilizing device. 10, 70 : Clinch nuts 13 : Annular edge 28 : Outer indentation 60 : Elongated plate 62, 64 : Orifices 66 : Inner indentation 72 : Plane sides 74 : Inner sides.</p> |
