The utility model discloses increase the conduction of magnetic flux between limit chip and the well chip, improved the SNR of magnetic head to improve magnetic head sensitivity, the outside of limit chip is with the retaining member when fixed, and the retaining member is to the limit chip application of force, and limit chip non -deformable guarantees limit chip magnetic inductivity.
Description
Technical field
This utility model relates to paper money counter or the magnetic head of self-help drawing money machine, particularly relates to the chip structure of a kind of bank-note counting cognitron magnetic head.
Background technology
The existing magnetic head for electronic equipments such as the POS, POS, ATM, has generally comprised shell and magnetic core, and shell plays shielding action, magnetic core is arranged on shell, magnetic core includes magnetic head and chip, and head read magnetic card also obtains signal, then the central processing unit that signal passes to electronic equipment processes.
As shown in Figure 1, existing chip is mainly made up of a chips 1 and two limit chips 2, two limit chips 2 points are arranged on chips 1 left and right sides, each limit chip 2 is connected to the two ends up and down of chips 1, wherein the upper end of chips 1 is the signal end obtaining magnetic card signal, an antifreeze plate 3 it is equipped with between this signal end, each limit chip 2 and chips 1.After installation, the lower end of chips 1 and limit chip 2 leave gap 4, and this gap 4 directly decreases the conduction of magnetic flux between limit chip 2 and chips 1, thus reducing the signal to noise ratio of magnetic head, causes magnetic head sensitivity decrease；The outside of limit chip 2 with locking member fixing time, locking member exerts a force to limit chip 2, contacts out-of-flatness due to limit chip 2 and chips 1, is easily caused limit chip 2 and deforms, affect limit chip 2 permeability, thus reducing signal to noise ratio and the sensitivity of magnetic head further.
In view of this, it is necessary to the chip structure of existing structure magnetic head is improved.
Summary of the invention
The technical problems to be solved in the utility model, it is in that to provide the chip structure of a kind of bank-note counting cognitron magnetic head, including chips and two limit chips, two limit chips divide and are arranged on the chips left and right sides, each limit chip is connected to the two ends up and down of chips, the upper end of described chips is the signal end obtaining magnetic card signal, at this signal end, an antifreeze plate it is equipped with between each limit chip and chips, the both sides of the signal end of described chips are equipped with mounting groove, and described antifreeze plate is located in this mounting groove.
Further, the plane that described antifreeze plate and limit chip abut against is the first contact surface, and the plane that described chips lower end and limit chip abut against is the second contact surface, and described first contact surface and the second contact surface are substantially on same perpendicular.
Further, the width of described mounting groove is 0.1～0.15mm.
Further, the thickness of described chips is 0.3～1.0mm.
Further, the cross section of described chips is convex shape.
This utility model arranges mounting groove by the signal end in chips, after making limit chip install with chips, the gap reduction of the lower end of chips and limit chip even eliminates, and adds the conduction of magnetic flux between limit chip and chips, improve the signal to noise ratio of magnetic head, thus improving magnetic head sensitivity；When the outside of limit chip is fixed with locking member, locking member exerts a force to limit chip, and limit chip is unlikely to deform, it is ensured that limit chip permeability.

Detailed description of the invention
Refer to Fig. 2,3,4, it it is the chip structure of a kind of bank-note counting cognitron magnetic head as most preferred embodiment of the present utility model, including chips 1 and two limit chips 2, chips 1 and limit chip 2 each through punch forming, two limit chips 2 points are arranged on chips 1 left and right sides.The thickness W1 of this chips 1 is 0.3～1.0mm, and cross section is convex shape.Each limit chip 2 is connected to the two ends up and down of chips 1, the upper end of this chips 1 is the signal end obtaining magnetic card signal, at this signal end, an antifreeze plate 3 it is equipped with between each limit chip 2 and chips 1, the both sides of the signal end of this chips 1 are equipped with mounting groove 4, and the width W2 of this mounting groove 4 is 0.1～0.15mm.This antifreeze plate 3 is located in this mounting groove 4.The plane that this antifreeze plate 3 and limit chip 2 abut against is the first contact surface, the plane that this chips 1 lower end and limit chip 2 abut against is the second contact surface, this first contact surface and the second contact surface, substantially on same perpendicular, so just make the minimum even gapless in the gap between chips 1 lower end and limit chip 2.
In sum, this utility model arranges mounting groove by the signal end in chips, after making limit chip install with chips, the gap reduction of the lower end of chips and limit chip even eliminates, add the conduction of magnetic flux between limit chip and chips, improve the signal to noise ratio of magnetic head, thus improving magnetic head sensitivity；When the outside of limit chip is fixed with locking member, locking member exerts a force to limit chip, and limit chip is unlikely to deform, it is ensured that limit chip permeability.
Above in conjunction with accompanying drawing, this utility model is exemplarily described; obvious this utility model implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model design carries out with technical scheme; or not improved design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
