The shock absorbing silicone protects the memory chip 52 from vibration interference. The low-temperature bismuth alloy fuse wire is disconnected when being heated at 92 degrees, so that heat is prevented from being transmitted to an internal chip through a conduction band. Meanwhile, the low-temperature bismuth alloy fuse wire surrounds the nanometer heat insulation material in a Z shape, so that external heat cannot be directly transmitted to the internal chip through the wire passing groove, and a better heat insulation effect is achieved
Wherein, the upper cover 3, the lower cover 1 and the protective shell body 2 are tightly connected by using bolts 13 or nuts 14, and the joint surface is provided with a high-temperature resistant insulating silica gel seal ring 6.
The PCB 51 is disposed at the center of the protective casing 2, and the surface of the PCB 51 is parallel to the bottom surface of the protective casing 2.
The heat insulation material is characterized in that the heat insulation material is of various types, a round PCB is taken as the center, the heat insulation material is a high-temperature-resistant nano heat insulation material from outside to inside in the shell 2, the heat insulation material is a high-temperature-resistant nano heat insulation material with a smaller heat conductivity coefficient inside, 7 is a 1100 type nano heat insulation plate A, 8 is a 1100 type nano heat insulation plate B, 9 is a 1100 type nano heat insulation plate C, 10 is a 950 type nano heat insulation plate A, 11 is a 950 type nano heat insulation plate B, and 12 is a 950 type nano heat insulation plate C; 2 layers of nano heat insulation materials are arranged in the shell of the protective shell, and the heat conductivity coefficients of the nano heat insulation materials are reduced from outside to inside in sequence.
Wherein, insulating silica gel packing ring wraps up the multilayer nanometer thermal insulation material respectively all around, nanometer thermal insulation material's clearance becomes the Z shape, the data connecting wire that uses low temperature bismuth alloy fuse to make also becomes the Z shape through nanometer thermal insulation material's clearance, this length that can lengthen the data connecting wire that low temperature bismuth alloy fuse made prevents because the data connecting wire that protective housing casing body 2 and protective housing upper cover 3 intensification too fast low temperature bismuth alloy fuse made fails in time the heat conduction effect that fuses and form, leads to PCB board 51 and data chip 52 high temperature and damage. The data connecting wire 53 made of the low-temperature bismuth alloy fuse wire is Z-shaped, the fuse wire is connected to the PCB after bypassing the insulating silica gel gasket from the side and the lower part, and the liquid after the fuse wire is fused is structurally ensured to avoid flowing onto the PCB, so that the PCB and the data chip are damaged due to overhigh temperature. As shown in fig. 3, a is a bismuth alloy fuse wire threading slot, and B is a memory chip placement area.
Wherein, the low-temperature bismuth alloy fuse wire can be a tin bismuth alloy wire.
The utility model discloses a data storage box's major structure is cylindrical, saves space, and is firmer. The nanometer heat-insulating material has very low heat conductivity coefficient, is A1-grade non-combustible material, has the highest fire resistance temperature of 1600 ℃, and is non-toxic and environment-friendly. When the nanometer heat-insulating material is used, the fireproof heat-insulating PCB is taken as the center, and the material can be uniformly distributed around the PCB.

The utility model discloses use multiple type nanometer thermal insulation material, practice thrift the cost, the ladder heat dissipation makes thermal-insulated effect show more. The high temperature resistance temperature of the nano heat insulation material is in direct proportion to the heat conductivity coefficient, so the higher the high temperature resistance, the higher the heat conductivity coefficient of the material is. The highest fire-resistant temperature of the nanometer heat-insulating material imported by Germany at present reaches 1100 ℃, while the highest fire-resistant temperature of the nanometer heat-insulating material manufactured in China can only reach 950 ℃. The nanometer heat-insulating material with the highest fire-resistant temperature reaching 1100 ℃ imported from Germany is used as a first layer, and the nanometer heat-insulating material with the highest fire-resistant temperature reaching 950 ℃ manufactured in China is used as a second layer. Through various types of nano heat insulation materials, the heat conductivity coefficient of the nano heat insulation material of the second layer inside is lower than that of the first layer, so that the effect is better than that of the nano heat insulation material of which the highest fire resistance temperature reaches 1100 ℃ and which is imported by Germany and is used for two layers at the same time. The nano heat insulation material manufactured in China has an advantage in price compared with the nano heat insulation material imported from Germany.
The utility model discloses in, the inside data connecting wire of protecting sheathing all uses the data connecting wire that low temperature bismuth alloy fuse made. If use the data connecting wire (like copper wire, silver wire etc.) of high temperature fusing material, when protecting sheathing casing and protecting sheathing upper cover temperature were higher than the temperature that data storage chip can bear but did not reach the fusing temperature of high temperature fusing material, the data connecting wire can regard as hot good conductor, with temperature rapid transfer to PCB board and data storage chip to lead to the data storage chip to damage because of the high temperature. When the data connecting wire made of the low-temperature bismuth alloy fuse wire is used, the fusing temperature is lower than the temperature which can be borne by the data storage chip, so that the fuse wire is fused to be in a liquid state before the temperature of the protective shell body and the protective shell upper cover is higher than the temperature which can be borne by the data storage chip, the data connecting wire cannot serve as a heat conduction material, and the temperature of the protective shell body and the protective shell upper cover can be transmitted inwards only through a nanometer heat insulation material.
However, the foregoing detailed description is merely exemplary in nature and is intended to better enable one skilled in the art to understand the patent, and is not intended to limit the scope of the patent; any equivalent alterations or modifications made according to the spirit of the disclosure of this patent are intended to be included in the scope of this patent.
