Magnetic head spring plate structure

Abstract

The invention relates to a magnetic head spring plate structure which comprises a seat body, a fixed base board, a clamping spring plate and a magnetic head module, wherein the seat body comprises a first seat board and a second seat board; the first seat board is provided with a first through hole; a clearance is arranged between the first seat board and the second seat board; the fixed base board is arranged on the first seat board, the center of the fixed base board is provided with a second through hole, and both sides of the second through hole are respectively provided with a third through hole; the clamping spring plate is stacked on the fixed base board, the center of the clamping spring plate is provided with a fourth through hole, and both ends of the clamping spring plate respectively penetrate through the third through holes so that the clamping spring plate is fixed onto the fixed base board; and the magnetic head module penetrates through the first through hole, second through hole and fourth through hole, and used for contacting a card so as to read information.

Description

technical field [0001] The invention relates to a magnetic head shrapnel structure, in particular to a magnetic head shrapnel structure with a fixing method. Background technique [0002] It has become an indispensable part of modern social life to use various financial magnetic cards as payment and transfer media in daily life. The application of other magnetic cards is also becoming more and more widespread, such as magnetic card access control locks, identification magnetic cards, etc., so the magnetic head fixing structure of the card reader used to read the magnetic card tape, with the expansion of the use of magnetic cards, Also more important. [0003] When the magnetic head of the card reader reads the tape data of the magnetic card, they must be closely attached to each other so that the magnetic head can effectively read the data of the tape. Therefore, the magnetic head must be combined with an elastic element. The magnetic head can provide a moderate relative m...

Problems solved by technology

[0005] However, the known magnetic head shrapnel are directly fixed on the base body by screw locking or soldering. Although it is the simplest and cost-effective way, when the magnetic head or the magnetic head shrapnel needs to be disassembled and replaced due to damage, It takes more time and manpower to remove the screws or destroy the solder, which is the biggest disadvantage of this fixing method

[0006] In addition, when the magnetic head shrapnel is fixed on the base body by means of screw locking in the prior art, it is easy to have uneven locking pressure, resulting in poor reading of the card and even damage to the parts.
