Abstract
The utility model provides a container for a magnetic card. The container is made of soft magnetic material. The container is suitable for making various magnetic fields which are used and are residual be put to register various information.
Description
The utility model relates to a kind of container of placing magnetic card.
All kinds of magnetic cards of current use promptly come the card of recorded information with residual magnetic field, as the credit card of issued by banks, the shareholder's card of stock exchange's distribution and the phonecard of telephone office's distribution etc. in use all should be avoided contacting with the ferromagnetism article.And existing technology is just made protective coat or box with non-magnet material, and this class shielding container can only prevent friction, can not prevent the pollution of space magnetic field to magnetic card.Wear in present all kinds of magnetic cups, magnetic therapy under the increasing situation of magnetic article such as thing, the magnetic card that this class writes down various information with residual magnetic field very easily is subjected to the pollution of the space magnetic field that the magnetic article produce, and makes the information disorder, and influence is normally used.
The purpose of this utility model is to come the magnetic card of recorded information that a kind of placement container that can reduce the space magnetic field pollution is provided to all kinds of with residual magnetic field.
The utility model is achieved like this: utilize soft magnetic material to have the advantages that magnetic conductivity is good, be difficult for being magnetized, make the container of a sealing with soft magnetic material.Then in magnetic field, the magnetic field intensity in the container will weaken greatly, just can play and reduce the chance that magnetic card is subjected to the space magnetic field pollution.This container can be made various required container as siliconized plate, iron-nickel alloy etc. through punching press by the metal material with soft magnetic characteristic.For example use the thick iron-nickel alloy plate punching out of 0.1～0.8mm such as Fig. 1, Fig. 2, Fig. 3, style shown in Figure 4, or make by the magnetic card size with the compound substance that accompanies soft magnetic material and to form.Compound substance as shown in Figure 5, its making can be like this: spraying one deck soft magnetic material (2) on the one side of auxiliary material (1), as manganese-zinc ferrite, on the coating of soft magnetic material (2), paste lining (3) again, lining (3) can be synthetic leather, leather, and auxiliary material can be a textile.
Claims (1)
- A kind of suitable placement is all kinds of writes down the container of the magnetic card of various information with residual magnetic field, and it is characterized in that: container is to be made or made by the compound substance that accompanies soft magnetic material by the metal material with soft magnetic characteristic.
