Portable storage device with electrostatic control function

The present invention relates to a portable storage device with electrostatic protection function, in particular to a metal casing portable storage device, and a device having at least one conductive dielectric block for directly guiding the static charge of the metal casing to the ground path.

According to the traditional portable storage device, the portable storage device is widely used in large-capacity storage and portable data applications. In particular, the storage and memory data capacity of the portable disk is increasing day by day, and the dependence on the portable disk is relatively increased. In addition to the trend of increasing the capacity of storage and memory data, there is a relatively high demand for the external protection measures of the flash drive. For example, the traditional portable disk is widely used to provide the inner circuit board to cover and protect the plastic. The case can provide anti-static voltage or signal surge and other abnormal voltage and signal interference to the internal circuit board, but the electrostatic voltage protection capability is only ±2KV (crouch) or 4KV, which is required for higher electrostatic protection quality (for example) : The electrostatic drive voltage of 8KV or more) can not meet its requirements, and because the plastic shell structure is relatively fragile, it is easy to be broken due to external force, foreign matter pressure or heavy fall, resulting in inconvenience and trouble of the portable disc. And, the traditional plastic case of the pen drive, its visual appearance and sense of value is poor, often may be made The sight of the person is neglected and easily lost or accidentally discarded. Therefore, if the circuit board of the portable disk is covered with a metal casing, the strength, hardness, texture and value of the body of the portable circuit board can be increased. However, when the metal case is carried by the user or held by a finger, the external noise will be violent and static. The electrical environment and the static electricity of the human body, so that the metal casing is electrostatically charged, so that the static electricity of the metal casing directly causes electrostatic interference and damage to the circuit board of the portable disk and the stored circuit components thereof, causing the circuit board of the portable disk to malfunction. Damage, and thus the loss of important data stored in the flash drive circuit board, is currently a problem to be solved in the metal case.

In addition, in the related prior patent technical documents, such as the invention patent of "Electrical Device Housing Structure with Electrostatic Protection" of the Republic of China Patent No. I334673, it is disclosed that the use of a first member, a connecting member, a first The two components and the circuit structure of the circuit component are wrapped such as a flash drive or a USB connector. Although it can be used to protect the static electricity from interference and damage to the flash drive, the structure is complicated, and an additional housing is required, which cannot be included in the original portable body. In addition to the additional cost and volume of the accessories, the housing structure of the disc cannot be applied to the flash drive of various shapes of the outer casing, which limits the application scope.

The conventional portable disk and the case of the previous case do not have good static guiding grounding measures, and should not be used with a metal casing or an antistatic casing, but the additional cost and volume of the accessory are required, and the casing cannot be applied to different shapes. The pen drive is used.

The purpose of the present invention is to provide a portable storage device having an electrostatic protection function, comprising a portable circuit board, an insulating inner casing, at least one conductive dielectric block and a metal outer casing, wherein the portable circuit board Having a data storage function, one end is provided with a USB metal connector for connecting to a USB port of an electronic device for reading the stored data in the flash drive circuit board, and the insulating inner casing covers the portable circuit board to make the a USB metal connector is exposed at one end of the insulating inner casing, and at least one slot is disposed at one end of the insulating inner casing, the groove is received by the conductive medium block, and a receiving groove is formed inside the metal casing, and the receiving groove is included in the insulating inner casing Hold to make the conductive The dielectric block is connected between the inner wall of the metal casing and the USB metal connector of the flash drive circuit board to form a path of electrostatic conduction grounding, thereby guiding the electrostatic grounding on the metal casing.

The effect of the built-in storage device with electrostatic protection function of the present invention is that the conductive medium block is filled between the inner wall of the receiving groove of the metal casing and the USB metal connector of the flash drive circuit board to form an electrostatic guide. The grounding path can be used to connect the static electricity of the metal casing directly to the electronic device via the USB metal connector when the USB metal connector is connected to a USB device such as a computer, a notebook computer, a tablet computer, or the like. The grounding terminal of the USB device of the device will not cause static electricity to interfere with and damage the flash drive circuit board, which can greatly improve the electrostatic protection capability of the portable circuit board, and can completely eliminate the electrostatic interference and damage of the portable circuit board. The problem is to greatly improve the reliability and security of data storage for the operation of the portable storage device.
