Description

[Detailed Description of the Invention] The present invention provides an engaging tool using a permanent magnet, in particular, suppresses as much as possible the occurrence of magnetic disturbance due to the magnetic lines of force of the permanent magnet used, and improves the engagement performance of the male engaging tool. The present invention relates to the disclosure of an engaging female fitting structure.

Therefore, in the conventional engagement odors using permanent magnets of this type, the main focus has been on effectively drawing out the adsorption force, and there has been no risk of accidents due to generated magnetism, especially magnetic tape, etc. The destruction of the magnetic recording portion of magnetic cards, magnetic chips, etc. by the lines of magnetic force of the permanent magnets used has hardly been considered. Some attempts have been made to interpose a magnetic shield plate on the magnetic pole surface of the permanent magnet to prevent the destruction of the magnetic recording part. If these tapes or cards come into direct contact with the magnetic shield plate attached to the magnetic pole surface of the permanent magnet used, there are no measures in place to prevent such contact, and most of the information recorded magnetically on this tape will be lost. It has been destroyed. The female engaging tool of the present invention is capable of preventing damage caused by lines of magnetic force caused by the permanent magnets used, which had been overlooked in previous engaging tools, particularly magnetic cards such as cash cards, magnetic tickets such as subway tickets, etc. The invention is intended to provide an engaging odor that prevents the magnetic recording portions of various types of magnetic tapes from being destroyed by lines of magnetic force.

Furthermore, the female engagement tool according to the present invention is intended to provide a female engagement tool that can prevent the mechanical displacement of the suction surface with the male engagement tool, and can continuously maintain an effective suction state. It is.

As a means to specifically solve the above problem, the engaging hole la according to the present invention has an engaging hole la facing from one magnetic pole surface a to the other magnetic pole surface b. A ferromagnetic plate 2 is attached to the magnetic pole surface b' of the permanent magnet 1, and the permanent magnet 1 and the ferromagnetic plate 2 form a mirror-sized cylinder with a bottom. The hole la of the permanent magnet 1 is placed inside the non-magnetic case 6 which has a hole 6b suitable for the non-magnetic case 6.
A green flange 6M of the hole 6b is provided inside the hole 6M each time the green flange 6M is engaged, so that it is held integrally and is attached to the surface of the non-magnetic case 6 on the magnetic pole surface a side of the permanent magnet 1 so as to be able to be adsorbed and removed. ferromagnetic plate 3
and the ferromagnetic birch 4 and the ferromagnetic birch 5 protruding from both or one of the ferromagnetic plates 2, or the ferromagnetic birch 4 and the ferromagnetic birch 5 with the ferromagnetic plate 2 or the ferromagnetic birch 5. Ferromagnetic plate 3

This permanent magnet 1 is equipped with a ferromagnetic plate 2 on one magnetic pole face b and a ferromagnetic plate 7 on the other magnetic pole face a, and the ferromagnetic plates 2 and 7 are A permanent magnet 1 is placed inside a non-magnetic case 6 having a cylindrical shape with a bottom, and the permanent magnet 1 and the ferromagnetic plate 2 are held together by a locking piece 6c provided at the edge of the entrance of the non-magnetic case 6. and 7 are integrated and attached.

The non-magnetic case 6 has a hole 6b at the bottom that passes through the hole la of the permanent magnet 1, and a rim 6b' is provided toward the inside of the hole 6b. The outer circumferential green of the facing non-magnetic case 6 is raised to form a convex edge 6a, and a concave ridge into which the ferromagnetic plate 3 of the male engaging tool described below is attracted and engaged is provided on the surface of the non-magnetic case 6. It is.

There is a considerable magnetic gap between the ferromagnetic camphor 4 reaching the upper edge of the opening of the hole la of the permanent magnet 1 having such a structure, and the inner wall of the hole la. A mounting washer 8 is installed vertically on the ferromagnetic plate 2 through a gap that does not cause a short circuit to the inner wall of the ferromagnetic plate 2, and then has bent leg pieces 8a, 8a on the ferromagnetic plate 2.
