New description: [New technical field] This creation is about a machine for reading electronic storage media, especially for structures that eliminate electromagnetic waves and static electricity. [Prior Art] Today's electronic products are designed to meet the requirements of miniaturization, high performance, high precision, high reliability, and high response. The distribution density of circuit components is too high, and the size of the circuit is greatly reduced. The more compact the circuit becomes, the more components will be squeezed into a small space 'increasing the chance of interference, among which Electromagnetic interference (EMI) and noise are most troublesome. EMI suppression targets are mainly divided into Radiation and Conductivity. (9) Her Glycerix electromagnetic interference. Conductive EMI is the transmission of noise through the power supply line, so the EMI generated by the electrical devices connected to the same power system. They will interfere with each other via the power line. Therefore, for the regulation of conductive EMI, it is first necessary to effectively measure the conductive EMI generated by the electronic components, and then select an appropriate component value design filter according to the result to prevent and control. Fortunately, it is directly transmitted through the open space, and does not need to be transmitted through any transmission medium, so it can only be solved by means of Shielding or Grunding. Furthermore, as long as it is an electronic device, different levels of static electricity are generated during operation, and these #electric residues may also adversely affect electronic components. M302749 / The current card reader for reading electronic storage media, which is used to eliminate light-emitting legs or static electricity. 'Mainly, the metal plate is placed at the position where the casing is close to the connector, and the metal plate is connected with the conductive wire. Then, the conductive wire is connected to other conductors, thereby excluding the EMI and static electricity generated by the connector. [New content] The structure of the conventional card reader is used to eliminate EMI and static electricity. Since the metal plate and the wire must be separately installed, the components are more, the assembly is more numb, and the manufacturing cost is higher. Therefore, the present invention is mainly aimed at solving the above-mentioned conventional card reader's lack of structure for eliminating EMI and static electricity. The main ship of the present invention is that the connection body of the needle machine is directly fabricated from a metal sheet having a conductive property, and the first and second conductive sheets are respectively extended from the two sides of the metal sheet by the first conductive The sheet contacts the metal casing of the card reader, and the second conductive sheet contacts the memory card inserted into the card towel, so that EMI and static electricity generated by the connector and peripheral electronic components are transmitted through the conductive sheet to eliminate . The creative method of the present invention is to integrally form the first and second conductive sheets on the metal 4 by using a stamping forming technique, so that the conductive sheets are inclined to make the conductive sheets elastic relative to the metal sheets. The metal piece is directly mounted as a connector housing after being connected to the port. Therefore, after the metal casing of the card reader is assembled, the first conductive piece is directly pressed into contact with the metal case to complete the grounding, and the second conductive piece is completed. It is then provided to and remembers to pass bribes and static electricity to the outer casing.
