Problems solved by technology

[0002] When installing various cards (such as: memory card, display card, sound card, network card, etc.) Dirt will be absorbed on the finger, and oxides will be produced on the surface of the gold finger. These dirt or oxides will affect its conductivity, resulting in unstable or malfunctioning of the card. The gold finger must be wiped to remove the gold The dirt or oxides on the fingers are cleaned. The existing method is to use a block eraser to wipe the gold fingers of the card. On the one hand, this method takes a long time to wipe, and on the other hand, the residue left on the gold fingers It is not easy to remove, and may accidentally damage the components on other parts of the card when wiping

Embodiment Construction

[0007] see figure 1 , the present invention includes eraser 1, the middle of described eraser 1 is provided with oblique groove 11, straight groove 12 and arc groove 13 successively from top to bottom, described oblique groove 11, straight groove 12 and arc groove 13 mutually Connected. The material used for the eraser 1 is rubber.

[0008] When wiping the card, first insert the golden fingers of the card from the inclined slot 11 and the straight slot 12 of the eraser 1 in turn, and then press the two sides of the eraser 1 moderately with your hands to make the two sides of the straight slot 12 close to the card. After the golden finger, the eraser 1 can be moved back and forth along the golden finger of the card to wipe, or the golden finger of the card can be moved back and forth in the straight groove 12 of the eraser 1 to wipe.

Abstract

The invention discloses an eraser, comprising an eraser (1). The eraser is characterized in that an oblique slot (11), a straight slot (12) and an arc slot (13) are sequentially arranged in the middle of the eraser (1) from top to bottom. The oblique slot (11), the straight slot (12) and the arc slot (13) are mutually communicated. The eraser (1) is made of rubber. The eraser is simple in structure, good in wiping effect, high in efficiency, low in cost and mainly used for wiping golden fingers of parts such as a memory card, a display card, a sound card and a network card in a computer.

Description

technical field [0001] The invention relates to an eraser, in particular to an eraser for wiping golden fingers on components such as a memory card, a display card, a sound card, a network card and the like in a computer. Background technique [0002] When installing various cards (such as: memory card, video card, sound card, network card, etc.) in the computer, insert their respective gold fingers into the corresponding slots of the motherboard for installation, but it takes a long time and the gold Dirt will be adsorbed on the finger, and oxides will be produced on the surface of the gold finger. These dirt or oxides will affect its conductivity, which will cause the card to work unstable or not work normally. The dirt or oxides on the fingers are removed. The existing method is to use a block eraser to wipe the gold fingers of the card. On the one hand, this method takes a long time to wipe, and on the other hand, the residue left on the gold fingers It is not easy to r...
