Description

electronic card connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector connected with an electronic card.

【Background technique】

Electronic cards used in computers include multimedia memory cards or memory cards. At present, memory cards on the market have various specifications such as Secure Digital Card (SDC for short), Muti Media Card (MMC for short), Smart Media Card (SMC for short), Memory Stick Card (MSC for short), MemoryStick Duo Card (MS-Duo C for short), Memory Stick Pro HG Card (MSHG C for short), XD-Picture Card (XDC for short), Compact Flash Card (CFC for short), etc., Since the contact positions of the memory cards of different specifications are different, the electrical connectors that need to be mated and plugged are different for the memory cards of different specifications.

In order to achieve convenience in use, manufacturers try their best to integrate various types of electrical connectors into an electrical connector suitable for memory cards of several specifications.

Please refer to Figures 1A and 1B. Currently, MSC has two different specifications, namely Memory Stick Card (hereinafter referred to as large card) and Memory Stick Duo Card (hereinafter referred to as small card). One end of the large card 10 and small card 15 are respectively set. There are contacts 11 and 16 in the same arrangement. The large card 10 is thicker and wider than the smaller card 15. In addition, SDC also develops a small card, called mini-SDC for short. As shown in Figure 1C, the mini-SDC18 is roughly the same as the small card 15 is equal in width and shorter, and one side thereof is provided with a breach 19, and this small card 15 side then does not have breach.

In this way, how to make a multi-card common connector so that the large card and the small card can be electrically connected to the same terminal when inserted, and both the large card and the small card can be stably locked is a problem that is not easy to achieve with the current connector. Because if the card slot that can lock the small card is designed in the connector, the big card or other cards will be blocked by the card slot and cannot be inserted, so the current connector is only provided with the card slot that locks the big card, and The small card is elastically pressed on both sides and above by the shrapnel, but this design cannot make the small card firmly positioned and the structure is complicated.
