[0002] Patent No. 200810086843.2 discloses a magnetic head for reading card data of a credit card authentication terminal and a magnetic head that cannot illegally obtain card data from a signal line derived from the magnetic head. Inside the case, a wire frame on which the electric wires are wound is provided, and a through hole is provided on the surface of the shielding case opposite to the opening, so that the core member whose end protrudes from the wire frame is exposed from the through hole to the outside of the shielding case. , set the lead pins connected with the winding wires of the wire frame, fill the resin into the hollow core in the shielding case to form a magnetic head, set the lead pins in the filled resin inside the shielding case, and connect the flexible circuit board to the lead pins One end of the flexible circuit board is led out from the opening to the outside. The two lead pins of each coil are arranged separately, and the user can easily read the signal on the magnetic head pin, so that the magnetic head cannot achieve confidentiality. effect

Abstract

The invention discloses a magnetic head supporting encryption of a magnetic card. The magnetic head comprises a magnetic head shell, a coil framework arranged inside the magnetic head shell, a coil wound around the coil framework, and chips clamped in an axial cavity of the coil framework, wherein an open part and a through hole are formed in the parts, located on the two sides of the coil framework, of the magnetic head shell respectively, the chips protrude out of the through hole, terminal pins are arranged on the surface of the coil framework and are located at the same end of the coil framework, and the ends of the coil are wound around the terminal pins. Due to the fact that the terminal pins are arranged at the same end of the coil framework, larger space is provided for the magnetic head shell, problems existing in installation of encrypting and decoding chips are solved, and meanwhile, the problem of the magnetic head wire open circuit caused by miniaturization of the magnetic head is solved.

Description

technical field [0001] The invention relates to a magnetic head, in particular to a magnetic head supporting magnetic card encryption. Background technique [0002] Patent No. 200810086843.2 discloses a magnetic head for reading card data of a credit card authentication terminal and a magnetic head that cannot illegally obtain card data from a signal line derived from the magnetic head. Inside the case, a wire rack on which the wires are wound is provided, and a through hole is provided on the surface of the shielding case opposite to the opening, so that the core member protruding from the wire rack at one end is exposed from the through hole to the outside of the shielding case. , set the lead pins connected with the winding wires of the wire frame, fill the resin into the hollow core in the shielding case to form a magnetic head, set the lead pins in the filled resin inside the shielding case, and connect the flexible circuit board to the lead pins One end of the flexibl...
