Abstract:
1. A multiple-in-one memory card insertion seat comprising: a common terminal seat; a metal cover disposed on a connected side of the common terminal seat, the metal cover being insulated from a grounding point of a PCB to remove a grounding function of the metal cover; a common insertion slot defined between said common terminal seat and said metal cover; a matched slot defined in the common insertion slot, the matched slot being configured for insertion of an MS memory card; a plurality of multi-conductive terminal groups disposed in the common terminal seat, the plurality of multi-conductive terminal groups including an MMC4.0 terminal group, an SD terminal group, an XD terminal group, and an MS terminal group to provide conductive connections corresponding to various memory cards; wherein a first pin of said XD terminal group has no electrical connection; and wherein said matched slot is shifted toward a side of said common insertion slot toward said first pin such that when an MS Duo short card or MS Pro Duo short card is inserted along with an adapter card into the matched slot an outer metal layer of the adapter card is prevented from contacting both first and second terminals of the XD terminal group; whereby circuit damage caused by an accidental short circuit between the first and second terminals of the XD terminal group or by accidentally grounding the nineteenth or twentieth terminals of the XD terminal group through the outer metal layer of the adapter card and the first pin of the XD terminal group is avoided.
