## Background
BACKGROUND
1. Technical Field
The present disclosure generally relates to cards used in electronic devices, and particularly to a surface contact card holder for an electronic device.
2. Description of Related Art
Surface contact cards having special circuits are widely used in portable electronic devices to enhance or specialize the functions of the portable electronic devices. For example, a subscriber identity module (SIM) card in a mobile phone can dedicate the mobile phone's functions to the SIM card owner. By changing SIM cards, a single mobile phone can be used by many different SIM card owners as a personal phone.
Although surface contact card holders are simple, it can be difficult to remove the surface contact card from the surface contact card holder.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
The disclosed surface contact card holder holds surface contact cards such as SIM cards, compact flash cards (CFs), multimedia cards (MMCs), and others. The disclosed electronic device, shown in the exemplary embodiment as a mobile phone, can alternatively be a personal digital assistant (PDA), camera, recorder, or other device remaining well within the scope of the disclosure.
FIG. 1 shows a surface contact card holder, which receives a surface contact card 50. The surface contact card holder includes a main body 10, a printed circuit board 16, a cover 30, and a pivotal shaft 35. The printed circuit board 16 is positioned at one side of the main body 10. The cover 30 is pivotably and slidably connected to the main body 10 by the pivotal shaft 35. The printed circuit board 16 has a connector 161.
Referring to FIG. 2, the main body 10 is assembled in a housing of an electronic device or is integrally formed with the housing of the electronic device. The main body 10 has a first surface 101 and a second surface 102. The first surface 101 defines a side slot 11, a receiving groove 14, and a through hole 141. The side slot 11 is adjacent to a first side of the receiving groove 14. The connector 161 is exposed via the through hole 141. The first surface 101 defines a positioning groove 17, a latching groove 18, and a block 25 between them at a second side of the receiving groove 14. The positioning groove 17 and the latching groove 18 communicate with the receiving groove 14. The positioning groove 17 has a bottom surface 171 and a positioning hole 172. The latching groove 18 has a bottom wall 180 and a stepped edge 181. The block 25 defines a notch 251 in an inner surface of itself toward the bottom surface 171. Referring to FIG. 3, the second surface 102 defines a recess 103 containing the side slot 11. Two latching portions 21 are formed on the recess 102 and are at opposite sides of the side slot 11. Each latching portion 21 defines a containing groove 211.
The cover 30 is made of metal. Note that as used herein, “made of metal” may mean or include a non-metallic material coated with a metallic (magnetic) material. The cover 30 includes a cover body 31, a hinge portion 311, a latching tab 32, an extending plate 33, a first finger 371, and a second finger 372. The cover body 31 is slidably received in the receiving groove 14. The hinge portion 311 is substantially cylindrical and extends from one side of the cover body 31. The hinge portion 311 is shorter than the side slot 11, allowing the hinge portion 311 to slide in the side slot 11. The pivotal shaft 35 is received in the hinge portion 311. The latching tab 32 and the extending plate 33 extend from another side of the cover body 31 and are spaced from each other. The latching tab 32 is slidably received in the positioning groove 17, and the extending plate 33 is slidably received in the latching groove 18. A protrusion 321 is formed on the latching tab 32. The first finger 371 is located adjacent to the hinge portion 311, and the second finger 372 is located adjacent to the extending plate 33.
To assemble the surface contact card holder, referring to FIGS. 4 and 5, the cover 30 is positioned above the receiving groove 14, and the hinge portion 311 is aligned with the latching portions 21. The pivotal shaft 35 extends through the hinge portion 311, with its opposite ends latched into the containing grooves 211. The first finger 371 is received in the side slot 11, and the second finger 372 is exposed from the latching hole 182. The first finger 371 and the second finger 372 electronically connect to the printed circuit board 16.
To insert the surface contact card 50 into the holder 200, the latching tab 32 and the extending plate 33 are pulled away from the cover 30. The surface contact card 50 is inserted into the receiving groove 14 of the main body 10. The cover 30 is pivoted around the pivotal shaft 35 to cover the receiving groove 14. The latching tab 32 is received in the positioning groove 17, and the extending plate 33 is received in the latching groove 18. Then, the cover 30 is slid until the protrusion 321 is latched into the notch 251 and the extending plate 33 is latched by the stepped edge 181 for preventing the cover 30 from moving. This structure allows the surface contact card 50 to be held steadily by the cover 30.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
