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'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.
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, in which:
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 personal digital assistant (PDA), camera, recorder, or other device, while remaining well within the scope of the disclosure.
The first housing 10 and the second housing 20 may be portions of the electronic device. In an exemplary embodiment, the first housing 10 is an outer housing of the electronic device, and the second housing 20 is a middle housing of the electronic device. The PCB 14 may be disposed between the first housing 10 and the second housing 20. The first housing 10 defines a button hole 125. The second housing 20 defines a receiving groove 21 and a slot 23. The receiving groove 21 is configured to receive the tray 50, and includes an entrance 213 allowing the tray 50 to enter within the entrance 213. The slot 23 is at one side of the receiving groove 21, and communicates with the receiving groove 21. A first post 233 is disposed at one end of the slot 23, and a notch 235 is defined at the other side of the slot 23. The bottom surface of the receiving groove 21 defines an opening 27 and a hole 28. The opening 27 allows the surface contact card 70 in the tray 50 to be electronically connected to the PCB 14. Pins 25 are positioned around the receiving groove 21. A cover 29 is used for covering the receiving groove 21, and defines pin holes 291 corresponding to the pins 25.
The ejecting mechanism 40 includes an elastic member 41, a slidable block 43 and a connecting rod 45. The elastic member 41 may be a substantially helical spring, and one end of the elastic member 41 is placed around the first post 233. Referring to
The tray 50 defines a channel 54 for receiving the surface contact card 70. A button 53 is formed at one end of the tray 50. A guiding member 55 is formed at a bottom of the tray 50 for being slidably received in the hole 28. A protrusion 56 protrudes from one side of the tray 50 for engaging in the depression 449.
During assembly, the slidable block 43 is received in the receiving groove 21 and the slot 23. The elastic member 41 is respectively placed around the first post 233 and the second post 4333. The surface contact card 70 is inserted into the tray 50. Then, the tray 50 is slidably received in the receiving groove 21. Referring to
Referring to
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.
