Description of creation (1) [new type belongs to this creation provides a connection path to u external static electricity [previous technology such as the first where the whole 1 2 is the main electrical equipment and electrical equipment electricity. In addition, the technical field of the memory card insertion circuit 15] relates to the grounding technology of the connector inside the card reader. The purpose is to integrate the main system of the card reader into a plastic material. The grounding SB port is effective. The grounding structure of the connector to avoid disturbing the electrical components of the card reader. ] The diagram is a schematic diagram of the internal structure of a conventional card reader. The card reader 10 is composed of a circuit board located inside the casing 11 and the circuit board 12 is provided with a USB port 13 for communication with The circuits (not shown in the figure) are connected to each other, and the circuit connection of the card reader 10 is provided, and the circuit board for the operation of the card reader 10 is supplied. The overall electrical engineering constitutes the memory card and the second step, and more of them The card can be connected and connected in the case 1; however, once the opening of the case is lost, the direct access to the case circuit 1 5 and other general readers 1 1 are inserted into the card 5 case 1 1 main body 1 1 electrical element 1 1 Mechanical component control electrical card setting machine 1 4 Socket setting machine 1 0 1 1 Use the internal parts of the body barrier to create at least 10 and prepare the electricity as a whole. 0 The toilet is equipped with a recording interior for recording < The section circuit board has a connection and is connected to the memory in the card reader circuit. It is set in the case memory card and connected to the memory card, and the capacity 12, even the connector 1 4 circuit board 1 1 1 0 and the 0 card insertion. The opening of the body 1 1 is easy to pass, so the opening is easy for the outside, so it is also possible to use it for the inside. There is a product on the front side, and it can be inserted and exchanged on the front side, so that the continuous phase insertion will also form the product of the static electricity passage. Because the product is

M268674 IV. Creation instructions (2) Electrostatic discharge (ESD) of electrical components such as circuit 1 5 will cause damage to the memory card. Therefore, the connector used in portable devices such as card readers must be improved. Anti-static discharge (ESD) capability. The improved anti-static discharge (ESD) technology used by Muyu Card Reader 10 is mainly provided with a metal shield layer 2 0 'on the outer cover of connector 丄 4, and further the metal shield layer 2 0 and the inductor, Passive components such as electrostatic discharge protection diodes are connected to improve the anti-static discharge (ESD). However, the main body of 'connector 1 4 is mainly formed by injection molding of plastic materials, and its metal shielding layer 20 is stamped by metal. It is processed and manufactured, so the whole connector 14 must be processed through different processing technologies and equipment to complete the main body and the semi-finished product of the metal shielding layer 20, and then the assembly process is performed to assemble the metal shielding layer 20 and the connector 14 The combination of the main body not only increases the manufacturing cost of the connector, but also cannot effectively increase the connector's production capacity. In particular, under the limited supply space of the card reader 10, in order to improve the anti-static discharge (ESD) effect, it must be minimized. In addition, passive components such as inductors and electrostatic discharge protection diodes are configured on the circuit board 1 i, which not only occupies the circuit board 1 1], but also reduces the related circuits. Total flexibility. [New content 1 This book "Card reader: 2㊁ :, grounding structure", its card reader is also composed of a circuit board inside the housing as the main body, the circuit board is provided with 11 s B port for electrical equipment The circuit is connected and connected on the circuit board.

Creative instructions (3) There is at least one connector for the insertion of the memory card; the main system of the connector is made of plastic materials into A. ^ The point is: even the "Hungarian" has a plug-in shield. The structure of the structure and the grounding circuit of the connector " The metal shell of the SB port, constitutes a connector that can be connected to the U metal shell through 耵 sb 逯 to the grounding circuit of the electrical equipment, and the connector of the f Grounding construction. To prevent static electricity hazards through proper management, the main bottle logic can be processed and manufactured by using plastic shot occupants, and the assembly with the metal shielding layer can be omitted ^: ΪΪ Lower connector [...] and effectively improve the connector [Implementation] The structure of the operation = work, and the structure of the reader of the entire book "grounding structure of the connector of the card reader", the first picture and the second As shown in the figure, the circuit board 12 is also the main body of the integrated card reader 10, which is located in the housing 1 丄. The circuit board 1 2 ^ β has U = B port 1 3 for use and use. The electrical & equipment of the card reader 10 is connected, and constitutes the circuit connection between the card reader 电气 〇 and the electrical equipment, and supplies the power required for the operation of the card reader 10; similarly, the circuit board 1 At least one connector 丄 4 is provided on 2 for the insertion and removal of the memory card, and integrated circuits 丄 5 and other electrical components are provided on the circuit board 11 to control the operation of the two card machines 1 〇, and further Memory card and electrical equipment circuit connection. Also, the front surface of the casing 11 is provided with the insertion portion of the connector 14
