Abstract

The invention relates to the field of instrumentation and relates to the mounting of intra-block screens and partitions, housings, frames and racks of electronic equipment. The purpose of the invention is to increase the mechanical strength and manufacturability. The connection of two mutually perpendicular parts contains a fastening screw placed in the hole of one of the parts to be joined, an H-shaped floating nut with a threaded hole in one of the parallel sides with an emphasis on its lower base, installed in the window of the other part. A retainer in the form of a pin, rivet, or chuck is made under the base of the abutment. The parts are fastened by placing the floating nut in the window of one of the fastened mutually perpendicular parts, and in the hole of the other part - the bolt. 1 3. p. F-ly, 5 ill.

i The invention relates to instrumentation, and can be used for the con- struction of housings, frames, and racks of electronic equipment, as well as for fixing the in-block screens and partitions.

The aim of the invention is to increase the mechanical strength and manufacturability of the preparation.

FIG. 1 depicts a compound, an ebychian species; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - ekno; in fig. 5 - floating nut.

Adjacent two mutually perpendicular parts contain a fastening screw 1, zazmeshenny in the hole 2 (not shown) EDN of the parts 3, the floating nut 4 installed in the upper part of the window 5 of the other part 6 at its edge 7, while the mountaineer 8 of this edge tightly the surface 9 of the other part abuts due to the guaranteed clearance h between this surface and the base of the floating nut, on the lower base of the floating nut there is a stop 10, under the base of which a retainer 11 is made in the form of a pin, rivet or puckle, the side of which is convex It is located under the base of the stop. The floating nut is H-shaped with a threaded hole 12 in one of the parallel walls 13, and the width f of the fixing grooves is greater than the thickness of the part S in which the floating nut is placed. In the upper base (Fig. 3) of the floating nut, a groove 14 is made, the width of which is equal to the width of the locking grooves, while the groove of the window is placed in the groove, the end 15 of which interacts with the base of the groove 16 when fixing the fastening screw. I However, for the floating nut in detail (Fig. 4), the expansion was made in the lower part, having a base 17 and side walls 18 of the upper part of the window adjacent to its upper base, while the shape of the window is T-shaped, butt end 15 The base of the window is parallel to the edge of the part. The floating nut (Fig. 5) is made in accordance with the shape of the window, made in one of the parts, while the cross section shows the threaded hole of the nut, denotes the base of the groove, as well as the base of the fixing grooves and the end 19 of the floating nut protrusion placing the floating nut in the part window.

The connection works as follows.

In the lower part of the window 5 (Fig. 4), in the immediate vicinity of the base 17, a floating nut 4 (Fig. 1) is inserted to mate the surface of the stop 10 with the surface of the part 6 and move it to the upper position, after which the fixer 1 is installed or are it in the form of puklevka

Moving the floating nut along the arrow (Fig. 1) along the fly is carried out by the gap fi between the ends of the side walls 18 of the window 15 and the bases of the fixing grooves (Fig. 2), and in the transverse direction due to the difference in the width of the fixing groove and the thickness S of the part 6, while the floating nut can move relative to its axis. The movement of the floating nut 4 ensures the attachment of the fastening screw 1 placed in the hole of the part 3 with the threaded hole of the floating nut, while ensuring that the surface 9 of the part 3 is tight to the end 8 of the part 6.

The proposed compound allows to increase the mechanical strength of more than 5 times, manufacturability approximately 2 times.

Claims (2)

1. The connection of two mutually perpendicular parts, containing a fastening screw placed in the hole of one of the parts, an N-shaped floating nut in cross section with a threaded hole on the upper end of the nut, mounted in a window on the edge of the other part, and a retainer, that, in order to increase the mechanical strength and manufacturability, the floating nut is made with an emphasis on the opposite side of the nut, parallel to the axis of the threaded hole and placed on the surface of the part with a window that can be blocked izhney part of the window, in the upper part of which is set Floating nut and retainer fixed on the parts under its emphasis. 2. Connection according to claim 1, characterized in that a groove is made on the upper base of the floating nut, in which the edge of the window is located, located on the edge of the part in which the floating nut is installed.
