Magnetic head with novel structure

Abstract

The invention relates to the field of magnetic heads, in particular to a magnetic head with a novel structure, which comprises a mounting plate, a fixed seat and a shell, fixed blocks are fixed on the two sides of the mounting plate, a fixed hole penetrating through the fixed block is formed in one fixed block, a slot is formed in the other fixed block, and a base is fixed on the upper end surface of the mounting plate. The fixed seat is fixed to the upper end face of the base, an induction chip is fixed to the top of the fixed seat, a connecting wire electrically connected with the induction chip is further fixed to the bottom of the fixed seat, a connecting groove assembled with the induction chip in a matched mode is formed in the top of the shell, and a fixing groove is formed in the inner wall of the shell. A limiting groove is further formed in the inner wall, below the fixing groove, of the shell, a positioning block used in cooperation with the limiting groove is fixedly arranged at the top of the base, and a limiting block assembled in cooperation with the fixing groove is further fixed to the fixed seat. The device can well protect the induction chip from being collided and scrapped.

Description

【Technical field】 [0001] The invention relates to the field of magnetic heads, in particular to a magnetic head with a new structure. 【Background technique】 [0002] A banknote detector is a machine that verifies the authenticity of banknotes and counts the number of banknotes. Due to the large scale of cash circulation and heavy cash handling work at bank teller counters, banknote counters have become an indispensable device, integrating counting and counterfeiting. With the development of printing technology, copying technology and electronic scanning technology, the level of counterfeit banknote manufacturing is getting higher and higher. To get higher, we must continue to improve the counterfeit identification performance. According to the different trajectory of the banknotes, the banknote counters are divided into horizontal and vertical banknote counters. There are usually three ways of identifying counterfeit: fluorescence identification, magnetic analysis, and inf...

AI Technical Summary

Problems solved by technology

[0003] The magnetic head generally includes a mounting plate assembled with the banknote detector, a fixed seat is fixed above the mounting plate, an induction chip is fixed on the top of the fixed seat, and a shell is fixed on the outer peripheral side of the fixed seat. The sensing chip is exposed from the top of the shell and contacts the banknote through the sensing chip. Afterwards, to identify banknotes, but the magnetic head is produced separately and then supplied to the banknote detector manufacturer for assembly. When the magnetic head is transported and assembled with the banknote detector, it is easy to cause the exposed sensing chip to collide and wear, resulting in the scrapping of the sensing chip.
