Description

[Detailed Description of the Invention] The present invention relates to a case in which a toroidal coil can be easily stored and fixed.

The present invention is a case that stores and fixes a toroidal coil vertically and its lower half, and both sides of the toroidal coil are extended somewhat along the circumference rather than a semicircle, and this extended part is used as an elastic coil holding arm. The present invention relates to a structure of a toroidal coil fixing case made of a synthetic resin material, which has four cylindrical parts, and has elastic valve strips on both end surfaces of the recessed parts that abut the middle length of the toroidal coil.

Conventionally, various methods have been used to fix a toroidal coil to equipment or equipment, such as fixing it with adhesive or fixing it by passing a screw through the center hole of the coil.

However, the method of fixing the coil with adhesive requires a means to temporarily hold the coil until the adhesive hardens, and the method of fixing the center hole with a screw may not be possible depending on the number of turns, or Consideration must be taken, such as using a slightly thicker core so that the screw can pass through the hole, and sometimes it is necessary to use an insulating elastic material for insulation, so that the coil can be easily and securely fixed. There are various drawbacks.

The present invention eliminates such drawbacks and makes it possible to firmly fix the coil.

An embodiment of the present invention will be described with reference to the drawings.The entire case is made of synthetic resin, and the four parts 1 that house the coil constitute elastic coil restraining arms 4 that extend somewhat along the circumference from a semicircular cross section.

Both end surfaces of the four parts are semicircular as shown in FIG. 1 to take advantage of the elasticity of the coil holding arm 4.

The bottom of the case is flat and has a mounting hole 5 in the collar 6.

It also has a hole 7 for pulling out the lead wire of the coil downward if necessary.

An elastic valve strip 2 having a diameter slightly larger than the middle length of the coil is provided from the upper edge of the semicircular plate constituting both end surfaces of the recess so as to hang down inside the recess as shown in figures a and c.

A notch 3 is provided in the valve strip 2 to increase its elasticity.

Next, to describe how to use the case of the present invention, press open the holding arm 4 and push the toroidal coil vertically into the recess 1.

The lower half of the coil housed in the case is covered within the case, and a part of the upper half of the coil is held down by a holding arm 4, allowing it to be pulled out upward and preventing it from moving up and down.

Further, the valve-like protrusion piece 2 presses down the side surface of the lower half of the coil with its elastic function, thereby preventing movement and vibration in the thickness direction of the coil.

The case is attached to a device through a mounting hole 6 provided in the collar 5, and the terminal lead wire of the coil winding can also be drawn out through the through hole 7.

The toroidal coil fixing case of the present invention stores the coil in the case and then attaches it to the base of the device, or installs the case and then stores the coil in the case.

Additionally, the stored coils are pressed against each other from the top, bottom, left and right, so they can withstand vibrations.

As explained above, the case of the present invention has the advantage that it has a simple structure, is easy to handle, and can securely fix the toroidal coil in a vertical position without the need for conventional adhesives or screws.
