1. A memory protection device, comprising:
insulating heat-conducting bars, for being respectively provided on upper ends of slot arms at two sides of a memory connection base and for covering up heat emitting holes which are provided at the upper ends of the slot arms to prevent dust from entering through the heat emitting holes, wherein each said insulating heat-conducting bar has a concave slot; and a heat-conducting mask for covering upon a whole of a memory bar and contacting with memory granules on the memory bar, wherein said heat-conducting mask has an upper end closed and a lower end open; upper parts of two ends of said heat-conducting mask are closed and are for connecting to two ends of a wiring board of the memory bar by clipping; lower parts of said two ends of said heat-conducting mask are open; two sides of said heat-conducting mask are T-shaped; said lower end of said heat-conducting mask contacts with said insulating heat-conducting bars; wherein said concave slot parallels with the slots of the memory connection base; said lower end of said heat-conducting mask is plugged into said concave slots, so that the memory bar is covered by said heat-conducting mask which closely contacts said insulating heat-conducting bar, in such a manner that a contact surface between the memory bar and air is greatly reduced and an oxidation speed of the memory bar is slowed down; wherein said concave slot is as wide as each said side of said heat-conducting mask, in such a manner that no gap is left between said heat-conducting mask and said concave slot, so that the dust is hardly able to enter said concave slot. |
