Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting nut for the purpose of directly attaching a nut used for fixing an electrical appliance to a rail or other groove at a desired position in the middle of the groove. It is something.

The conventionally known mounting putot has a semi-circular rectangular plate whose long side is larger than the groove width of the rail or other [hereinafter referred to as rail etc.], and whose short side is smaller than the groove width, and after dropping the plate. A structure that allows you to rotate the nut by AO degrees to qtr degrees and take it to the rail, etc. (Jitsukai Shohyo-3!; 9T 9''), or a structure with a width across flats that is larger than the width of the rail, etc. It is known that a square nut or a rectangular nut is inserted and latched from one side of the rail, etc. so that it can be moved to a predetermined mounting position (Jikko Getter 93g No. 1), but the former can be attached to any part of the rail, etc. Although it can be attached and detached in this position, there is a risk that it may come off due to rotation of the nut, and the latter must be inserted from the open end on one side of the rail etc. (therefore, it is impossible to attach it to the hole) Therefore, if the open end is on one side of the rail, etc., it cannot be used (for example, when the mounting 14 is punched and formed on the mounting board), and the open end on one side of the rail, etc. Even if there is an edge, when the nut is set on the board, the edge is usually closed and the mounting nut can be removed (because it is done like this, the number of nuts exceeds the required number by calculating in advance) If necessary, there was a problem in that the end of the rail etc. had to be opened and the mounting nut fitted in. Also, the short side of the rectangular mounting nut should be more than 1 times the diameter d of the screw hole provided in the plate. Since the length of the rail, etc., is long and requires 2d + α), the groove width of the rail etc. needs to be 2d + β (α × β) of course (for strength reasons). Therefore, if the groove width of the rail etc. is increased by 2 , □ Since there is a risk that the plate may curve when the instrument is installed, the plate must have a thickness that will not curve when tightened.

However, in this invention, the locking spring is detachably attached to a plate body having a vertical and horizontal width larger than the groove width of the V-ru, so the groove width may be slightly thicker than the screw hole diameter d (for example, 7 mm).
．． (approximately 2d), therefore, the thickness of the plate only needs to be strong enough to withstand tightening, and there is no need to consider curvature during tightening as in the past.

That is, to explain this invention with reference to an embodiment, a screw hole 3 into which a screw is to be screwed is provided in the center of a flat rectangular metal plate,
``Cut grooves DA and DA are provided on a pair of short sides of the hook plate l, respectively,
To the above-mentioned incision groove Hiro, pa, the opposite edge ta, r of the rail 3'
The latching spring 6 that latches with the ``b'' is fitted into the latching spring 6 so as to be separable from each other to form the mounting hole A.
is formed in the shape of a narrow annular gate with a side funnel shape, and a diamond-shaped ampullae Aaf is provided at the lower side of the side, and the width W of the ampullae is equal to or slightly larger than the rail groove width (W≧W1). .

This is to serve as a guide when fitting A onto the rail (Figure 6) and to prevent it from coming off during the fitting process. Further, the upper end of the latching spring rises obliquely upward from the metal plate surface and is bent into a plane M shape in order to be latched to the rail edge, but the shape is not limited to this. If the shape is to achieve this purpose, mouth-shaped, arc-shaped,
Alternatively, any shape such as a wavy shape may be used. Further, the shape of the side surface of the spring is not limited to the diamond-shaped enlarged portion, and it goes without saying that it may be a circular enlarged portion or a mere guide protrusion without the enlarged portion.

Next, the operation of dropping the mounting bracket (A) into the tray (Ns) of this invention will be explained. First, as shown in Fig. 6, place the lower end of the latch spring 6 against the rail lever and apply downward pressure as shown by the arrow 7+17) to push the enlarged part Aa of the latch spring 6 under the groove of the rail 2. Push one side of the metal plate l° diagonally in the direction indicated by the arrow, push it down in the direction indicated by the arrow, move it in that direction (Fig. 6), and then push the other side of the metal plate onto the rail S. If you push it under the groove, you can drop it in as shown in Figure S. Once installed, the mounting bracket (A) cannot be removed unless it slides all the way to the end of the rail.

The mounting nut of the above embodiment is installed into the groove of the rail/I/S with both ends open as shown in ii [Fig. Since they can be fitted freely in any position in the groove, it is only necessary to calculate the required number in advance and install the necessary number when installing the necessary ζ instruments. For example, as shown in FIG.
0, 'substrate 10 and layer L/5,''''
! (r) and screw A) and screw λ to secure it. In the above description, the substrate of the instrument is fixed to the rail, but it is also possible to fix the mounting plate to the rail and fix the instrument to the mounting plate. Since the spring of the present invention is formed by sequentially forming narrow metal rectangular rings using a molding machine, it is a one-end type, and the strength of each part is constant, making it possible to maintain a stable mounting condition. The metal rectangular ring is formed by stamping a plate material.

That is, according to the present invention, a screw hole is provided in the center of the plate body which is larger in length and width than the groove width of the rail etc., and a latching spring is fitted to this plate body, so that it can be attached to the rail etc. at any position. It has the effect of being able to be dropped in, and the groove width can be made as narrow as possible, so it is effective enough to withstand use even if the plate is made relatively thin.Also, since the spring is endless, each part can be easily The strength becomes constant and has the effect of maintaining the same strength.
