Improved magnetic head shrapnel structure

The present invention relates to a magnetic head shrapnel structure, and more particularly to an improved magnetic head shrapnel structure having a fixed manner.

The use of various financial magnetic cards for the payment and transfer of consumer goods in daily life has become an indispensable part of modern social life. The application of other magnetic cards is also becoming more and more extensive, such as magnetic card access locks, identification magnetic cards, etc., so that the magnetic head fixing structure of the card reader for reading magnetic card tapes is expanded with the use of magnetic cards. It is also more important.

When the magnetic head of the card reader reads the magnetic tape data of the magnetic card, it must be closely attached to each other, and the magnetic head can effectively read the data of the magnetic tape. Therefore, the magnetic head must be combined with an elastic component, and the elastic component is The elastic force enables the magnetic head to provide a moderate relative movement distance with respect to the thickness of the magnetic card. When the magnetic card passes through the magnetic head, the magnetic head is pushed by the magnetic card to generate an elastic restoring force to make the magnetic head adhere to the magnetic tape, and the magnetic tape is stored. data. However, if the head is too close or not tight enough to the tape, the friction will damage the head and the tape or cause a read failure when the tape slides over the head.

Please refer to the first and second figures at the same time, which are respectively a stereoscopic appearance exploded view and a combination diagram of a conventional magnetic card fixed structure of a card reader. A magnetic head A10 is fixed in the middle of a elastic piece A11, and the elastic piece A11 is attached. The two ends are respectively provided with a circular hole A12 and an elongated hole A13, and the elastic piece A11 is locked on the body A16 by two screws A14 and A15, and the magnetic head A10 is exposed in a card slide A17. When the card slides over the card slide A17, the magnetic head A10 contacts the magnetic tape of the card to read the data, and the magnetic head A10 is displaced by the card, and the elastic piece A11 is fixed with the circular hole A12 as the magnetic head is displaced. The hole A13 is a curved deformation of the pressing end, and the elongated hole A13 moderately provides the expansion and contraction space of the end displacement caused by the elastic deformation of the elastic piece A11, thereby preventing the magnetic head A10 from being in rigid contact with the magnetic tape and causing excessive wear and poor reading. situation.

However, the conventional magnetic head shrapnel is directly fixed to the base by screw locking or soldering. Although it is the easiest and cost-effective way, it must be spent when the magnetic head or the magnetic head shrapnel needs to be disassembled and replaced due to damage. More time and manpower for screw removal or damage to the solder is the biggest drawback of this type of fixing.

In addition, since the magnetic head spring is fixed to the seat by the screw locking method in the prior art, it is easy to have a non-uniform locking pressure, which causes poor card reading and even damage of the parts.
