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.
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 remaining well within the scope of the disclosure.
The tray 10 can be assembled in a housing of an electronic device or be integrally formed with the housing of the electronic device. The tray 10 includes a bottom plate 12, a number of side edges 13, two supporting plates 14, two limiting portions 15, an entrance 16, and two latching portions 17. The tray 10 is made of metal, and is formed by punching to a predetermined shape.
The side edges 13 perpendicularly extend from opposite sides and from one end of the bottom plate 12 opposite to the entrance 16. The supporting plates 14 horizontally extend from opposite side edges 13, and are parallel to the bottom plate 12. The supporting plates 14 with the side edges 13 and the bottom plate 12 cooperatively define a first receiving space 18 for receiving the surface contact card 100.
The limiting portions 15 are formed at two sides of the tray 10 adjacent to the entrance 16. A tab 151 and a finger 152 branch from each limiting portion 15. The tabs 151 are opposite to each other, and are parallel to the bottom plate 12. Each finger 152 extends towards a support plate 14, and inwards into the tray 10. Each of the latching portions 17 is formed on a support plate 14, and is higher than the supporting plate 14. The height of the limiting portions 15 relative to the bottom plate 12 is substantially equal to the height of the latching portions 17. A second receiving space 19 is defined between the supporting plates 14, the limiting portions 15 and the latching portions 17.
The sliding member 30 includes a main body 32 and a handle portion 34. The main body 32 is slidably received in the second receiving space 19. The main body 32 defines an opening 322 configured for allowing a connector to electrically connect to the surface contact card 100. Each of the two sides of the main body 32 define a notch 324. The fingers 152 are for latching in the notches 324.
To assemble the surface contact card holder 200, the main body 32 of the sliding member 30 is slidably received in the second receiving space 19. The supporting plates 14 support one side of the main body 32, and the tabs 151 and the latching portions 17 abut against the other side of the main body 32. The fingers 152 latch in the notches 324 to prevent the sliding member 30 falling out of the tray 10.
To insert the surface contact card 100 into the holder 200, the handle portion 34 is pulled away from the tray 10 until the fingers 152 abut against one end of the notches 324. A gap 40 is defined between the handle portion 34 and one end of the tray 10. The surface contact card 100 is inserted into a first receiving space 18 of the tray 10. Then, the tray 10 is slidably received in the second receiving groove 19. The surface contact card 100 and the sliding member 30 are received in two different receiving spaces, therefore when the sliding member 30 slides relative to the tray 10, the sliding member 30 does not force the surface contact card 100 to move. This structure allows the surface contact card 100 to be held steadily in the tray 10.
In another embodiment, the surface contact card holder 300 is generally the same as the surface contact card holder 200 of the first embodiment. In the second embodiment, the tray 10 includes two L-shaped limiting portions 25 and the sliding member 30 includes two elastic protrusions 36. A width between the limiting portions 25 is slightly smaller than the tray 10. When the sliding member 30 is received in the tray 10, the limiting portions 25 impede the protrusions 36 and prevent the sliding member 30 falling out of the tray 10.
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.
