るおそれがあった。BACKGROUND ART AND PROBLEMS Conventional clinch nuts have a disadvantage in that when they are fitted into and caulked into a mounting hole provided in a metal plate, the peripheral edge of the mounting hole is locally deformed and distorted. Such distortion increases as the thickness of the metal plate to which it is attached becomes thinner, resulting in the problem that the nut is not stably fixed to the metal plate. Additionally, there was a risk of damaging the threads of the nut body during caulking.
本発明は、上記従来の問題点を解決するものでナット本
体をかしめる際にこれを取り付ける金属板に局部的な歪

目的としている。The present invention solves the above conventional problems and provides a clinch nut and a clinch nut that can reliably prevent damage to the bolt threads without causing local distortion in the metal plate to which the nut body is attached when the nut body is crimped. The purpose is to provide a method for installing it.
発明が解決しようとする課題

する。Problems to be Solved by the Invention In order to achieve the above object, the clinch nut of the present invention is provided with a cylindrical protrusion protruding from the seat surface of the nut body concentrically with the screw hole on the seat surface side of the nut body. The inner periphery of the cylindrical protrusion has a diameter larger than the root diameter of the screw hole, and the inner periphery of the open end thereof has an outwardly expanding inclined surface, and the outer periphery of the cylindrical protrusion has an annular groove. It is characterized by the fact that it is provided.

At the same time, punch out a mounting hole in the metal plate to be attached. Simultaneously, emboss the peripheral edge of the mounting hole to form a convex curved part that engages with the annular groove, and fit the cylindrical protrusion of the clinch nut into the mounting hole. At the same time, after the convex curved portion is engaged with the annular groove, the open end of the cylindrical protrusion is expanded in the radial direction and fixed to the metal plate.

かしめられる。Effect: By the means described above, the cylindrical protrusion of the nut body is caulked with the convex curved portion of the metal plate engaged with the annular groove of the nut body, thereby preventing deformation of the metal plate due to pressure during caulking. Distortion is absorbed by the convex curved portion. Further, since the cylindrical protrusion has an outwardly expanding inclined surface on the inner periphery of its open end, it can be easily expanded and caulked in the radial direction with a small pressing force.
実施例 以下、本発明の実施例を図面に基づいて説明する。Example Embodiments of the present invention will be described below based on the drawings.

られている。1 and 2 show a clinch nut 1 according to the present invention, which has a cylindrical protrusion 5 on the seat 4 side of the nut body 2 concentrically with the screw hole 3, and a seat surface 4. It is placed more prominently. The inner periphery of the cylindrical protrusion 5 has a diameter larger than the root diameter of the screw hole 3, and has an outwardly expanding inclined surface 6 on the inner periphery of the open end 5a. Further, on the outer periphery of the cylindrical protrusion 5, an annular groove 7 is provided which extends outward and is recessed from the seat surface 4.

The open end 5a of the nut 1 is expanded radially outward and caulked, and the nut 1 is fixed to the thin metal plate 11 with the convex curved portion 13 sandwiched between the caulked portion 5b and the nut body 2. At this time, the caulked portion 5b is pushed into the recess formed on the back side of the convex curved portion 13, and does not protrude from the surface of the thin metal plate 11. Also,
Since the opening end 5a has an outwardly expanding inclined surface 6 on the inner periphery, the opening end 5a can be easily expanded in the radial direction even with a bunch 16 having a flat surface, and can be crimped with a relatively small pressing force. Is possible. Since caulking can be done with such a simple means, there is no need for specially shaped punches or dies as in the past, and there is an advantage that caulking can be done with a commercially available hammer or simple receiving metal fittings. Further, since the pressing force required for caulking is small, the thread of the screw hole 3 is not damaged by as much when the open end 5a is caulked.
