Problems to be solved by the prior art and the invention
An ordinary magnetic button used to hang a box, bag, bag, etc., consists of two parts, a button cover and a button body. The button upper lid is provided with a fixing leg, and the button body is composed of an outer shell, a magnet built in the outer shell, and a lower lid having fixed legs. The magnetic buttons are fixed to gloves, bags, etc., which need to be opened and closed at all times, via the fixed legs of the upper and lower lids, respectively, and used for opening and closing the lids of gloves, bags, etc. However, until now, such convenient magnetic buttons have not been used for items that always need to be opened and closed, such as coats, leather jackets and suits. The first reason is that the magnet of the ordinary magnetic button has weak magnetism (magnetic field strength of about 500 gaos). To increase magnetism, the size or thickness of the magnet must be increased. Normally, even 8 mm is not suitable for clothing. The second reason is that, with a normal magnetic button, it is not possible to provide a needle hole for fixing to a garment with a string like a normal button. The third reason is that the magnetic button is formed by press-forming an iron plate and subjected to plating or other rust-prevention treatment, but the problem of rust is still inevitable. The fourth reason is that magnetic buttons usually do not take into account the waterproofing problem and therefore cannot be washed with water.

Referring first to FIGS. 1 and 2, the magnetic button 1 of the present invention has a button body 2 which has a decorative front button surface 3. The front button surface 3 is a protruded extension plane, and the periphery is an edge 4 lower than the front button surface 3. A penetrating needle hole 5 for fixing the magnetic button 1 is formed in the edge 4. ing. The back surface of the button body 2 is a substantially flat back button surface 6. A chamber 7 is recessed between the front button surface 3 and the back button surface 6 to be isolated from the outside. A magnet 8 is housed in the chamber 7 of the button body 2. Both surfaces of the magnet 8 are N-pole and S-pole, respectively. The iron plate 9 whose shape and size correspond to the magnet 8 and whose peripheral edge extends in one direction is mounted thereon so as to surround the magnet 8. That is, the iron plate 9 is placed on one surface of the magnet 8. The height of the stretched rim is substantially the same as the thickness of the magnet 8.
[0008]
The button body 2 is usually circular, but may be square, elliptical, triangular or the like according to the decorative requirements of the garment. Various decorations are applied to the button surface 3 based on various requirements. The button body 2 is made of a non-magnetic material, and a material such as nylon, polyvinyl (PVC), or resin is selected. Button bodies are made in the usual way, based on different requirements and different materials. If polyvinyl is used as a raw material, a molding method may be used. The thickness D of the button body 2, that is, the vertical distance between the front button surface 3 and the back button surface 6 is 2.5 to 3.5 mm. The magnet 8 is made of a ferromagnetic alloy, for example, a strong alloy of neodymium, iron, and boron, and its magnetic field strength reaches 1500 Gaos, which is a usual magnet used recently for magnetic buttons (magnetic field strength is about 500 Gaos) is about three times larger. The thickness of the magnet 8 is 1.0 to 1.5 mm. However, even if the thickness of the magnet used for a normal magnetic button is 8 mm, the required magnetic force cannot be reached. The one usually used is a circle, one of which is an N pole and one of which is an S pole.
