Description

Technical Field

[0001] The present invention relates to the technical field of reader magnetic heads, and in particular to a multi-track magnetic stripe reader magnetic head with a new structure. Background Art

[0002] In the POS card reader, the magnetic stripe reader head is an important component. When making the card reader, the magnetic head needs to be installed and fixed inside the card reader shell. At the same time, a card swiping slot is opened on the shell, and the magnetic head is located inside the card swiping slot for swiping the card. When swiping the card, the card contacts the magnetic head, and the magnetic head reads the card information. At present, when installing the traditional magnetic head, a zinc-aluminum alloy bracket is used for hot die-casting, which is complicated and costly.

[0003] In the prior art, the positioning holes of the coil skeleton of the new structure are used to position the two magnetic tracks (magnetic heads) with the help of a special assembly fixture, and then the magnetic head chip is clamped with a spring sheet. The spring sheet includes a first fixing point clamped on the two magnetic tracks (magnetic heads) and a second fixing point clamped on the magnetic head shell. With the help of the elastic force of the spring sheet, the front and rear gaps of the magnetic head chip are closely contacted through the first fixing point, and the magnetic head is placed in the magnetic head shell without screw holes, so that the front mouth of the chip extends into the chip window on the R surface of the shell. With the help of the elastic force of the spring sheet, the magnetic head chip and the magnetic head shell are positioned and fixed through the second fixing point, and at the same time, the magnetic head shell and the magnetic head chip are kept in good contact. Through the grounding of the magnetic head shell, the magnetic head chip can also maintain good grounding performance. The magnetic head chip and the magnetic track are positioned and fixed by using the spring sheet and the coil skeleton, replacing the original zinc-aluminum alloy bracket, and the original fixing screws are cancelled. In the manufacturing process, the process of grinding the screw end can be omitted, which simplifies the production process, reduces the production cost, and improves the appearance of the magnetic head.
