Abstract

PURPOSE:To prevent the leakage of a line of magnetic force to the outside by attaching and fixing magnetic shielding plates to the upper and lower surfaces of a magent and generating an adsorbing effect by the adhesion and mounting of a male stud to a magnet surface. CONSTITUTION:The ferromagnetic plate 2 is brought into contact with one side of the magnetic pole surfaces of the permanent magnet 1 and the ferromagnetic plate 3 with the other magnetic pole surface, and both plates are fixed and set up integrally by a case consisting of a nonmagnetic blank while a projection 2a up to the upper end of a hole 1a is erected to the plate 2. The case 4 takes a cylindrical pan shape, a hole communicated with the hole 1a is formed to the inner bottom of the case, a hole collar 4b connecting being in contact with the inner circumferential edge of a hole in the plate 3 is formed and a pawl hole 4a is formed to an opening edge, the plate 3, the magnet 1 and the plate 2 encased in the case 4 are fixed and set up integrally by a turn-in to the surface of the plate 2 of said pawl piece 4a, and a cylinder body 13 made of synthetic resin is fitted tightly.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention utilizes a permanent magnet r to engage one of the engaging tools corresponding to the male tool! , a protrusion in the IC? Installation is done by minimizing the number of hooks on the end surface, which is an inconvenience.
- This relates to the disclosure of an engaging tool which is designed to prevent recording destruction (vt+) force in magnetic recording parts such as magnetic tapes, magnetic caps, cards, etc. when the engagement tool is swept away.

Therefore, in the past, this type of engaging rod has both male and female parts, and the magnetic lines of force in the case other than when the magnetic lφ1 path r is closed are approximately lateral as shown in Fig. 2. It swelled to a large extent, causing damage to the rTm tape, magnetic tape, magnetic card, etc. by 9 Jljli when the engaging tool came close to it.

In addition, in order to correct the disadvantage of using magnets, in which the attraction force in the lateral direction (on the magnetic attraction surface) is extremely weak, the magnetic attraction surface (with protrusions and recesses for engaging the magnetic attraction surface) is provided. In the previous precedent, it was considered indispensable to provide an engagement jL end face protrusion r corresponding to the male IC IL1, and it was said that it was essential to provide an engagement jL end face number protrusion r, and the engagement and disengagement were of course in this old engagement state? Even if V is used, the nuclear protrusion can cause various problems such as getting caught (induced warping).

In the past, when a female female was present, the magnetic field was generated on the magnetic pole surface of the permanent magnet, and this occurred at a position where the male + h female was relatively intersecting with the field. 2) In other words, the engagement operation is for I/E with suction force of the fin.
It acts from a distance, and slide operations at close positions, etc.
It is difficult ♂ and 1 is also V).

In view of the inconveniences in conventional RTI cases, this particular engagement has been specially devised.1. ＝It is a magnet I
Attach the upper and lower edicts of L+ with the magnetic shield plate R, and attach the magnet! This prevents the lines of magnetic force in the magnetic field from bulging out to the side for a long time, and also prevents the generation of lines of magnetic force that extend over the top surface of the shield plate. Due to the adverse effects of r-cutting, the male 1F1. i! ! , ri) It was purchased in such a way that the suction effect r occurs only after it is attached.

Hereinafter, an example of a typical flaw in the present invention will be explained with reference to the attached drawings of the engaging tool. : Permanent magnet '), one of the 6Bt ferromagnetic plates 121
