Field of the Invention The present invention relates to a memory card protector, and more particularly to a memory card protector for protecting a memory card having a plurality of electrodes in an electrostatic state. [Prior Art] In recent years, the function of the memory card is superior to that of the hard disk or the optical disk, and the advantages of small size and large memory capacity are often applied to electronic products such as digital cameras, mobile phones, and portable music. Also commonly used in the computer's external memory device. When carrying and transporting a memory card from an electronic product, in order to prevent the data or electronic circuits in the memory card from being damaged by static electricity during the process, the memory card is usually placed in a special carcass with protection function. Then start carrying and carrying. However, the biggest reason why the memory card is damaged by static electricity is the human limb. This is caused by the discharge caused by the user's charged limb (palm, etc.) touching the memory card package. This phenomenon causes the stored data or electronic circuits to be destroyed. For example, when the user walks on a carpet, if the humidity is 10 to 20%, the user's limbs can reach 35kV, and the humidity is 65 to 90%, which is 1.5 kV. If the charged finger is too close to or touches other conductive substances 200838779 (such as memory card), it will cause electrostatic discharge. Although the human body does not feel the discharge of 1~2 kV, it does not know that there is discharge. There will be a discharge situation that destroys the stored data. In order to avoid the occurrence of the previous situation, as shown in FIG. 4, a plurality of memory cards 34 are stored in a box 31 for storage. The box body 31 is provided with a card body frame 33 in the box body 32, which is 105 to 107 Ω. An electrostatically diffusing high-resistance conductive sponge having a degree of /cm 2 , when the memory card 34 is housed in the casing 31, the memory card can be brought into contact with the card body 33 by the outer surface of the memory card 34. 34 with electrostatic leakage. Reference [Non-Patent Document 1]: http : //www. nakabayashi. co. jp/products/brand/digio/memorycase.html ° When the memory card 34 is taken out by the cabinet 31, it needs to be in direct contact with a charged palm or finger. When the memory card 34 is touched, the discharge is inevitably caused. At this time, if a high-current micro current flows through the outer surface and leaks to the card body frame 33, problems can be avoided, but if the micro current does not pass through the card body frame 33, and is exposed The electrodes on the outer surface of the memory card 34 are transmitted inside, that is, the electronic circuit and the data are destroyed. As shown in FIG. 5, when the finger operates the memory card 34, in order to prevent the finger from directly touching the electrode 35 of the memory card 34, the electrode 35 is disposed in the recess 36 of the outer surface; but if the finger is charged, as long as the finger is too close The electrode 35 (although the electrode 35 is not touched) can cause discharge. At this time, since the electrode 35 is disposed in the recess 36, it is difficult to contact the card holder 33, and the electrode holder 35 cannot be contacted through the electrode 35 (the current will be from the electrode) 35 flows into the card holder 33) to protect the internal electronic circuit, so the design also has damage to the electronic circuit or data 200838779. That is, as shown in Figure 6, the design is that the groove 3 6 is narrow and can not be The soft card body frame 33 is inserted into the recess 36, and even if it has a thin strip (which is a rubber material) having a shape suitable for the recess 36, it is deformed during processing and is difficult to process. SUMMARY OF THE INVENTION The main object of the present invention is to provide a memory card that directly touches a memory card with a charged limb to cause a discharge, so that the electrical can be surely leaked without damaging the electronic circuit or the stored data inside the memory card. Protection. In order to achieve the above-mentioned purpose, the present invention is to protect a memory card having a plurality of electrodes in an electrostatic state, and includes a memory card storage device for accommodating a memory card and maintaining the state of the inserted memory card. The utility model has a socket and an electrostatic protection circuit, the socket has a slot and a plurality of electrodes, the slot is for inserting a memory card, the electrodes respectively corresponding to the electrodes of the memory card; the electrostatic protection circuit is connected by an electrode connected to the ground electrode The lead-wire is electrically connected to the socket, and has an electrostatic protection resistor connected in parallel with the grounding point through the electrostatic protection resistor. According to the memory card protection device of the present invention, if the memory card is inserted into the slot of the memory card receiving device, the electrodes of the memory card are connected to the electrodes of the socket. Therefore, by arranging the electrodes of the memory card in the narrow narrow grooves, the electrodes can be respectively connected to the electrodes in the socket. Moreover, each electrode other than the grounding wire in the socket is connected to the ground through a lower impedance than the impedance value of the memory circuit (eg, 200838779 500kO~2ΜΩ), so that the electrodes are connected in parallel to each other. The card and its electrodes are stored and held in a grounded state by electrostatic protection resistors. Therefore, when the electrostatically charged arm directly touches the memory card to cause discharge and current is input to the electrode of the memory card, since the electrodes of the memory card have been grounded below the impedance of the memory circuit, the discharge can be generated. The high-potential micro-current does flow out, effectively preventing the electronic circuit inside the memory card or the stored data from being destroyed. In order to further understand the present invention, a preferred embodiment is described _ and is described in detail below with reference to the drawings. [Embodiment] In the embodiment of the present invention, when the electrostatic card is directly touched by the memory card to cause the discharge, the charge of the memory card is surely leaked, so as to avoid the electronic circuit or the stored data inside the memory card. After being damaged, the memory card is inserted into the memory card storage device for storage and protection, and the memory card _ storage device is provided with a socket formed by a plurality of electrodes respectively connected to the electrodes of the memory card inserted into the slot, and Among the electrode connection wires of the socket, at least the electrodes other than the ground line have an electrostatic protection circuit in which the ground line is connected in parallel via an electrostatic protection resistor. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a memory card protector of the present invention, and Fig. 2 is a circuit diagram of the same.

The front end has a recess 2 for protecting the electrode 3 (including the ground electrode 3a), and the memory card 4 is inserted into the memory card accommodating device 5 after being affected by static electricity. The memory card storage device 5 has a cover β, in which a printed circuit board 7 is disposed, a socket 8 into which the memory card 4 is inserted, and an electrostatic protection circuit 9 connected to the socket 8; the socket 8 has a slot Each of the electrodes 11 corresponds to the electrode 3 and is electrically connected to the electrostatic protection circuit 9. The electrostatic protection circuit 9 is disposed on the printed circuit board 7, and is connected to the electrode 12 (excluding the ground electrode Ua). The wire 12 is connected in parallel with the grounding terminal 14 through an electrostatic protection resistor 13, and the electrostatic protection resistor 13 is The memory circuit impedance value is a low 5_Ω~2ΜΩ wafer type. The above is the structure of the present invention, and its action is explained below. If the memory card 4 needs to be loaded into the memory card protection gi for storage, the memory card 4 can be inserted into the slot 1{) of the socket 8 at the front end of the card 4, so that the memory card* is electrically connected to the electrodes of the socket 8. ;^. At this time, the bakelite (3) (the electric protection resistor 13 is connected to the grounding point 14, and the j is connected to each electrode 3 of the electrode η (the grounding electrode % is electrically connected to the grounding point 丨4 by the electrostatic protection resistor 13). If the memory card 4 is protected by the memory card, the charged palm 4 (8) touches the memory card 4, and the discharge occurs between the surface of the taker and the finger. The low-voltage static circuit has a low impedance of the electrostatic insulation 200838779 and is connected to the grounding point 14, so that the high-potential micro-current flowing through the electrode 3 flows out from the grounding point 14, thereby effectively preventing the electronic circuit in the memory card 4. Or the data stored in the electronic circuit is destroyed. Fig. 3 is another embodiment of the memory card protection device of the present invention, wherein a memory card protection cassette 21 is located in a box type carcass housing 22, the memory card protection 21 includes at least one memory card storage device 5 for accommodating at least one memory card 4 and holding the inserted memory card 4. The body casing 22 is made of a metal material for preventing accumulation of static electricity and not being affected by electromagnetic waves. The utility model relates to an opening and closing box formed by a body 23 and a lid 24, and has an elastic hinge 25, a spring 26 and a base 27, and the base 27 is provided with a four-connected card storage device 5; When the locking of the body 23 and the lid 24 is opened, the lid 24 can be opened by the elastic hinge 25. At this time, the spring 26 will interlock with the lid 24 to generate a plucking force to raise the base 27. The memory card storage device 5 of the susceptor 27 is similar to that shown in FIG. 1. The socket 8 of the memory card 4 and the electrostatic protection circuit 9 of the connection socket 8 can be mounted on the printed circuit board 7, and the socket 8 is provided.
