Specific embodiment

The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model Among described scope of embodiments.

As Figure 1-3, a kind of card connecting device for mobile terminal, including：Golden finger group 10 and Kato 20.Kato 20 are removably connected with golden finger group 10.

Referring to Fig. 1, golden finger group 10 includes some golden fingers 11, for being electrically connected with mobile terminal.

In the present embodiment, some golden fingers 11 are shaped as circular or strip.In other embodiment, the tool of golden finger 11 Space size, spatial form that shape be able to can be accounted for according to it etc. is set accordingly, can be triangle or square Deng.

Some golden fingers 11 are arranged in two-dimensional array.In the present embodiment, the spacing between each golden finger 11 is unanimous on the whole, It is evenly distributed.In other embodiment, the spacing between golden finger 11 can be with difference.
