1. Technical Field
The present disclosure generally relates to card use in electronic devices and, particularly, to a surface contact card holder for a portable 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 now increasingly in widespread use. These electronic devices enable consumers to enjoy technologically enhanced convenience in a wide array of environments. 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' 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, the engagement between the surface contact card holder and the surface contact card must still allow easy disengagement of the two.
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 present 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 portable 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.
Referring to
In this exemplary embodiment, the main body 10 is substantially rectangular, and mounted on the electronic device 200, here, a mobile phone. The main body 10 includes two sidewalls 123 and one end wall 125 connecting each other, thereby defining a receiving bay 12 and an open end 121. A bottom surface 122 of the receiving bay 12 positions a connector 15 with a plurality of electronic contacts for electrical contact with the surface contact card. Each sidewall 123 defines a notch 13, a guide groove 16 and a through hole 18.
The cover 30 is detachably attached to the main body 10. The cover 30 includes a baseboard 31 and two extending boards 33. The baseboard 31 defines a strip opening 312 communicating with one end thereof. The baseboard 31 defines a cutout 315 and a resisting portion 317 extending into the cutout 315 at two sides of the opening 312. Each resisting portion 317 has a bent end 3171 angling toward an inner side of the baseboard 31. Each extending board 33 forms a tab 333, a stopper block 336 and a post 338 respectively corresponding to the notch 13, the guide groove 16 and the through hole 18.
The impeller 50 is slidably received in the opening 312 of the cover 30. The impeller 50 includes a main portion 51 and a contact portion 52 integrally formed together. The main portion 51 is substantially I-shaped, and one side of the main portion 51 forms a plurality of ribs 511 contacting the main portion 51. The main portion 51 includes two side surfaces 53. Each side surface 53 defines a slot 55 for slidably receiving the baseboard 31 at two sides of the opening 312. The contact portion 52 is positioned at one end of the main portion 51. One side of the contact portion 52 projects higher than the main portion 51.
During assembly, referring to
In use, referring to
To remove the surface contact card 70, the impeller 50 is slid toward the open end 121, and surface contact card 70 is easily ejected from the receiving bay 12.
Alternatively, the impeller 50 may be replaced with other equally applicable structures. Further, cover 30 may be fixed to the main body 10 by welding.
Advantages of the surface contact card holder include secure connection with contact members as well as dependable containment of the card in the receiving bay, by means of the resisting portion. Operation of the impeller provides easy removal of the contact card. Therefore, the surface contact card holder offers both simplicity and ease of use.
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 invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
