Description

[Detailed Description of the Invention] The present invention relates to a transformer mounting frame for mounting a transformer.

Conventionally, when fixing a transformer used in electronic equipment to a case such as a molded chassis, a tapping screw is screwed into a mounting hole drilled in the transformer mounting frame to fix the transformer to the case such as a molded chassis. Since the mounting holes drilled in the transformer mounting leg were aligned with the mounting holes drilled in the transformer mounting frame and screwed in, screws were also required and installation was troublesome.

In view of this point, an object of the present invention is to provide a transformer mounting frame that allows a transformer to be mounted on the transformer mounting frame without using screws.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 4 are a plan view, a left side view, a right side view, and a front view of the transformer mounting frame, FIG. 5 is a front view of the transformer, and FIG. 6 is a bottom view of FIG. 5.

The transformer holding frame consists of a bottom surface 1 and left and right bent surfaces 3 and 2 bent upward on both sides thereof.

The right-turning curved surface 2 has a height t' which is higher than the plate thickness t of the transformer mounting leg 8 from the upper surface of the bottom surface 1, and a width L' whose lateral length is wider than the width of the transformer mounting leg 8. A hole 10 is provided at the center of the hole 10 in the lateral direction and extends downward from the curved surface 2.
A projection 5 having a width D' smaller than the diameter of the mounting hole 9 at one end is provided.

In addition, the left-turning curved surface 3 is provided with a hole 11 that extends from the upper surface to the lower surface in FIGS. At the same time, a semicircular projection 6 is provided in the center of the hole 11, extending downward from the other girder curved surface 3, and having a radius R larger than the diameter of the mounting hole 9 of the transformer mounting leg 8. Ori,
Further, on the upper surface side of the bottom surface 1 in FIGS. 1 and 2, a holding portion 13 having a narrow tapered portion 12 on one side is provided.

In addition, as shown in FIG.
! A notch 7 is provided at the corner of the l.

When installing the transformer shown in FIGS. 5 and 6 on the transformer mounting frame shown in FIGS. The eighth
As shown in the enlarged side view of the figure, the protrusion 5 is inserted into the hole 10 and into the mounting hole 9 of the mounting leg 8.

This is done by moving from the solid line in the direction shown by the two-dot chain line as shown in FIG.

Then, it rotates along the hole in the left side plate 3 in the direction of the arrow from the position indicated by the two-dot chain line in FIG. do.

The left-turning curved surface protrusion 6 enters the mounting hole 9 of the transformer when the L-shaped portion of the left-turning curved surface 3 is constructed as shown in FIG. By making the radius R1II (R>H) with a gap and pressing the periphery of the mounting hole 9, the left-turn curved protrusion 6 can be easily inserted into the mounting hole 9, and it can be held securely. .

As described above, the state shown in FIG. 11 is reached.

Then, by bending the holding part 4 shown in FIG. 10 upward, a part of the transformer is pushed as shown in FIG.
When untwisting, stop.

Further, the side of the pressing portion 13 that presses down a part of the transformer 10 is tapered 12, so that even if the holding portion 13 deviates somewhat from this position, it can be held securely by the bending angle.

As configured as described above, according to the present invention, there is no need for screw holes or screws in the transformer mounting frame when attaching the transformer to the transformer mounting frame, and the transformer can be mounted using only pressed parts. It is inexpensive because it can be fixed, and it is convenient because it can be easily installed and removed.
