Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure generally relates to card use 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&#39;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 may be simple, it can be difficult for the surface contact card to be removed from the surface contact card holder. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     The disclosed surface contact card holder can seat 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 PDA, camera, recorder, or other device, while remaining well within the scope of the disclosure. 
       FIG. 1  shows a surface contact card holder  100  mounted on an electronic device. The surface contact card holder  100  includes a first housing  10 , a tray  20 , and a second housing  30 . The tray  20  may be disposed between the first housing  10  and the second housing  30  to slidably receive a surface contact card. 
     The first housing  10  may be one portion of the electronic device, and includes a main section  102  integrally formed together with two sidewalls  104 . The main section  102  defines a receiving hole  11  and a cutout  12 . The cutout  12  is disposed at one side of the receiving hole  11 , and communicates with the receiving hole  11 . A first resisting edge  121  and a second resisting edge  122  are formed at two sides of the cutout  12  on the main section  102 . 
     Referring to  FIG. 2 , the tray  20  includes a rectangular plate portion  21 . A flange  23  protrudes from each long edge of the plate portion  21 . Two arrows  214  pointing in opposite directions and a label  215  are formed on one end of the plate portion  21  for guiding users when installing or removing the surface contact card. A positioning wall  22  and a stopper wall  24  are perpendicularly formed at the other end of the plate portion  21 . The flange  23 , the positioning wall  22 , the stopper wall  24 , and the plate portion  21  cooperatively define a receiving compartment  216  to receive the surface contact card. A latching tab  25  extends from one long edge of the plate portion  21 , and is disposed between one flange  23  and the positioning wall  22 . 
     The second housing  30  is attached to the first housing  10 , and includes a cover portion  31  and a frame portion  32  integrally formed together. The cover portion  31  includes a base plate  311  and two L-shape fixing plates  312  respectively extending from two sides of the base plate  311 . A receiving groove  313  is surrounded by the fixing plates  312  and the base plate  311 . One of the fixing plates  312  defines a slot  315  corresponding to the cutout  12 . The frame portion  32  includes an end wall  321  and two extending walls  322  formed at the two ends of the end wall  321 . The end wall  321  is integrally formed with one end of the base plate  311 . An opening  314  is defined in the end wall  321  communicating with the receiving groove  313  of the cover portion  31 . 
     During assembly, referring to  FIG. 3 , the tray  20  is slidably received in the receiving hole  11  of the first housing  10 , and the latching tab  25  is received in the cutout  12 . The flange  23 , the positioning wall  22 , and the stopper wall  24  protrude from the receiving hole  11 . Since a length of the receiving hole  11  is longer than the tray  20 , the tray  20  may slide a distance within a predetermined range. Then, the second housing  30  is attached to the first housing  10 . The extending walls  322  are latched with the sidewalls  104 . The end wall  321  is across the tray  20 . The base plate  311  of the cover portion  31  covers one part of the tray  20  with the positioning wall  22  and the stopper wall  24 . The fixing plates  312  are fixed to the first housing  10 . The slot  315  is aligned with the cutout  12  to receive the latching tab  25 . The receiving groove  313  and the receiving compartment  216  provide a space to receive the surface contact card. The surface contact card holder  100  may be fixed to an electronic device. The tray  20  may be supported by a portion of the electronic device (not shown) to prevent the tray  20  from separating from the electronic device. The tray  20  may slide between the first housing  10  and the second housing  30 . 
     In use, referring to  FIGS. 4 and 5 , a surface contact card  50  is taken here as an exemplary application for the purposes of describing details of the surface contact holder  100 . The surface contact card  50  is inserted into the tray  20  along the opening  314  to allow the surface contact card  50  to resist the positioning wall  22  and the stopper wall  24 . The tray  20  with the surface contact card  50  is pushed to slide toward the cover portion  31  until the latching tab  25  resists the first edge  121 . The surface contact card  50  is thereby held steadily in the first housing  10  and the second housing  30 . 
     To remove the surface contact card  50 , the tray  20  is pulled along the receiving hole  11  until the latching tab  25  resists the second edge  122 , and surface contact card  50  is easily removed from the tray  20 . 
     As described above, the exemplary embodiment provides a surface contact card holder for portable electronic devices, such as mobile phones. The surface contact card holder can be easily opened and more user-friendly. 
     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.
