Abstract
The utility model relates to a waterproof heat radiation type flash storage disc, which comprises a casing and a circuit board which is provided with a USB interface. The utility model is characterized in that the circuit board is wrapped with an insulating waterproof layer, and sealing elements are arranged at a circumferential wall of the USB interface of the circuit board at the position which is matched with the casing. Heat conducting materials are filled in a cavity body which is formed by the casing, the circumferential wall of the USB interface of the circuit board and the sealing elements. The flash storage disc has the advantages of scientific design, reasonable structure, compactness and simplicity, overcomes the defect which exists in the existing flash storage disc and has triple waterproof function and heat radiating function. The highest outer work temperature which is required when the flash storage disc is used can be improved to cause the circuit board to endure higher voltage, performance is stable and the service life of the flash storage disc can be prolonged.
Description
Technical field
The utility model relates to flash disk (USB flash disk), especially a kind of waterproof cooling type flash disk.
Background technology
Flash disk is a kind of miniature mobile storage product based on the flash technology, and it is connected with computer by USB interface, realizes plug and play, has characteristics such as small and exquisite, light weight, reliable, easy operating.Various digitized contents, from photo, computer data, music, can realize mobile storage by this series products, be very suitable for the industry that finance, IT, advertisement design, national defence, medical treatment etc. need frequent mobile storage data informations, backup information to dynamic image.Existing flash disk is made up of housing and the circuit board that sets within it usually, and an end of circuit board is provided with USB interface, and USB interface is stretched out from shell ends, realizes that by USB interface the housing interior circuit board is connected with the inserting of the corresponding USB interface of computer.It is little, in light weight that flash disk has a volume, carries advantages such as convenient, become the essential product of office automation already.But in flash disk is widely used, it is found that flash disk manufacturer is not as yet from considerations such as the environment for use of flash disk, weathers, therefore, the existing structure flash disk exists waterproof and dampproof poor performance, heat radiation to wait defective slowly usually, and above-mentioned defective will directly influence the stability and the useful life of flash disk performance.
Summary of the invention
The purpose of this utility model is the defective that exists at above-mentioned flash disk, and a kind of waterproof cooling type flash disk is provided.
The utility model waterproof cooling type flash disk comprises: housing and the circuit board that is provided with USB interface, and it is characterized in that: described circuit board is enclosed with insulating waterproof layer; Be provided with seal with the circuit board USB interface perisporium of housing matching part; Be full of in the cavity that housing and circuit board USB interface perisporium and seal constitute Heat Conduction Material is arranged.
Described insulative water-proof material layer is the methyl silicon resin performed polymer.
Described seal is a sealing rubber ring.
Described Heat Conduction Material can be a kind of in heat radiation oil, heat-conducting silicone grease, heat dissipating silicone grease, heat conductive rubber, the heat-conducting silicone grease.
The utility model waterproof cooling type flash disk design science, rational in infrastructure, compact simple, it has overcome the defective that existing flash disk exists, and has:
1. this flash disk has triple water-proof functions: not only the sealing of shell can waterproof; And after the shell bad seals, its heat sink material also has water-proof function; The insulative water-proof material layer that is wrapped on the circuit board also has water-proof function;
2. the Heat Conduction Material that is filled between housing and circuit board not only can improve the highest extraneous working temperature that requires when flash disk uses, and makes circuit board can stand higher voltage and stable performance; And can prolong useful life of flash disk;
3. the waterproofing design of this flash disk has adopted traditional waterproof sealing to combine with high-tech organosilicon material, need not to acquire special equipment, invests very low.
The concrete structure of the utility model waterproof cooling type flash disk is provided in detail by the following drawings and embodiment.
