17 fixations, remaining space is filled using resin in shielding case 15, and exposed wire connection terminal 16 is drawn on line bag 13.
Wherein, if using the component in shielding case 15 as an entirety（A component i.e. as magnetic card magnetic head, this Shen
It please middle abbreviation head stack）, assembling process is：Magnetic core group 12 is packed into clamper 11 and compressed；By left and right clamper 11
Relatively, line bag 13 is sleeved on clamper leg, and spacer shims 14 are put among two clampers 11, is then clamped two using clamp spring 18
Device 11 is clamped, and combines above-mentioned each component, the head stack after combination is as shown in Figure 4.
The magnetic head of prior art production, height is generally in more than 5mm, as various electronic technology by leaps and bounds develop,
It usually also needs to increase some other functional units in magnetic head to improve comprehensive Card Reader ability, causes in many narrow spaces
The problem of occasion can not be applicable in.
The content of the invention
The application provides a kind of magnetic card reader and its magnetic card magnetic head, and can solve the height of existing head stack can not adapt to
The problem of place of numerous narrow spaces.
A kind of magnetic card magnetic head that the application provides, it is described including shielding case and the head stack being sleeved in shielding case
Head stack includes a group or more of magnetic core groups, line bag, clamper, clamp spring, wire connection terminal and printed circuit board (PCB), described
Magnetic core group and line bag are fixed in the slot of clamper formation, are clamped two clampers of opposite installation using clamp spring；It is described to connect
One end of line terminals is connected with line bag, is connected after other end warpage in a manner of thermocompression bonding with the pad of printed circuit board (PCB).
Preferably, the printed circuit board (PCB) is hidden in a manner of encapsulating inside the shielding case.
Preferably, the wire connection terminal is U-shaped terminal；The printed circuit board (PCB) is flexible PCB.
A kind of magnetic card reader that the application provides, includes above-mentioned magnetic card magnetic head.
Compared with prior art, the application has the following advantages：
The application can not only reduce the overall height of magnetic head by bending wire connection terminal, can also increase and be welded with printed circuit board (PCB)
The contact area of disk improves welding effect；The pad of wire connection terminal and printed circuit board (PCB) is connected in a manner of thermocompression bonding, circuit board
Top will not generate tin head and additionally increase magnetic head height, so as to further reduce the height of magnetic head, solve existing magnetic head
Not the problem of height does not adapt to the application scenarios of narrow space.Further, since circuit board top there is not terminal exposing, magnetic is not being destroyed
In the case of head, the card information of magnetic head acquisition can not be obtained, therefore the security of information can be effectively increased.
