Since the contacts 11/12 of the module card 10 are made of metal, there is a phenomenon of oxidation. When plugging, it is necessary to rub a sufficient distance between the terminals 21/22 and the contacts 11/12 to scrape the contacts 11 Metal oxide on /12 ensures good contact between terminals 21/22 and contacts 11/12. [0004] Since the general module card 10 is inserted obliquely into the conventional card edge connector 20 (refer to the first figure) and then pressed down (see the second figure), the general terminal 21/22 is set.
