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
With the development of wireless communication and information processing technologies, portable electronic devices such as mobile phones are widely used. Surface contact cards having special circuits are used in portable electronic devices to enhance or add to the functions of the portable electronic devices. For example, a subscriber identity module (SIM) card can be placed in a mobile phone to 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.
However, conventional surface contact card holder includes a tray assembled to the mobile phone. Since the internal space of the mobile phone is very limited, the tray has to occupy the internal space of the mobile phone. Additionally, the tray also needs to be assembled. Thus, the assembly process is complicated.
Therefore, there is room for improvement within the art.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the surface contact card holder. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosed surface contact card holder can seat surface contact cards such as SIM cards, compact flash cards (CFs) and multimedia cards (MMCs), for example. The disclosed electronic device in the exemplary embodiment is a mobile phone, and can alternatively be a PDA, camera, recorder, or other devices, while remaining well within the scope of the disclosure.
The housing 10 defines a battery receiving cavity 12 for receiving a battery. The battery receiving cavity 12 is defined by a bottom portion 120, two first sidewalls 122, and two opposite second sidewalls 124.
Referring to
Each second beam 224 has a guiding block 26 at a distal end. The guiding block 26 has a slope 262, at a top surface, and an arcuate latching end 264. The slope 262 is configured for guiding the surface contact card 30 to slide in the receiving space 24. The arcuate latching end 264 is used for latching one end of the surface contact card 30.
The second beam 224, of the positioning portion 22 connected to the reinforcing beam 25, defines a notch 28 for allowing the second beam 224 to have enough elasticity to stretch under an outer force.
The printed circuit board 40 is positioned at another side of the housing 10. A plurality of contacts 42 are located on the printed circuit board 40, and they are received in the receiving space 24, for electronically connecting the surface contact card 30.
In use, referring to
To remove the surface contact card 30, an outside force is applied to the surface contact card 30 toward a direction of the entrance 242. The surface contact card 30 slides on the slopes 262, and the surface contact card 30 is easily removed from the housing 10.
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 is 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.
