Problems solved by technology
In the prior art, the gold finger oxidation problem of memory, boards and other devices has always been a problem that plagues computers, especially special-purpose computers, and has not been well resolved.
After the gold finger and reed are oxidized, it will seriously affect the performance of electrical connection and data communication, which will lead to unstable and unreliable operation of the computer system
Especially the salty and humid working environment on the coast or on the ship or frequent plugging and unplugging will accelerate this oxidation, resulting in a reduction in the electrical conductivity of the connection between the gold finger and the reed, and will directly affect the working stability of the computer in serious cases.

Embodiment
[0015] The inner size of the shield is smaller than that of the normal memory slot, so that the bottom plate of the slot can be better tightened after covering the slot, reducing the entry of oxygen and moisture. In addition, from the bottom view, it can be seen that there are convex strips on both sides of the inner side of the shield, which are also designed according to the structural characteristics of the memory and memory slots, so as to better clamp the memory and memory slots.
[0016] The size of the protective cover of the PCI / ISA board slot is also the same as the protective cover of the memory stick, which is slightly smaller than the size of the normal slot, so that the slot bottom plate can be better tightened after the slot is covered. There is a gap at the upper end of the protective cover to facilitate the insertion of the board. And there are small concessions at both ends of the gap to fully match the size and structure of the board.

The invention provides an anti-corrosion and oxidation method from salt spray for golden finger and its slot contact point, which uses the protective mask to cover the slot of Card or Memory, tighter with the card and golden finger inserted in the slot, to prevent the salt moisture from oxidized corrosion on the metal contact point, a. covering a elastic Card hood on the outside of the Card slot, which upside opens a crack for the golden finger to pass and insert into the slot; b. the memory golden finger inserts with the slot together, the whole of memory and memory slot are covered in the hood of elastic memory slot.
Description
technical field [0001] The invention relates to a protective device for a gold finger of a computer board card, in particular to a gold finger and a method for preventing salt spray corrosion and oxidation of the gold finger and its socket contacts, which can prevent dust, damp heat, and oxidation of the gold finger . Background technique [0002] At present, most of the boards or memory sticks used in the computer field are connected to the PCI bus and the ISA bus. The bus of such boards and the corresponding slots are inserted into the corresponding slots using golden fingers and connections. That is, the printed circuit contacts are arranged in rows on one side or both sides of the plug connector of the board, and the conductive reeds corresponding to the rows of contacts are arranged in rows in the plug slot. The rows of contacts on various boards are in the industry. called golden fingers. For example, PCI bus and ISA bus boards include graphics cards, multi-function ...
