## Title
Chip card holder and portable electronic device using the same

## Abstract

A chip card holder used to fixing a chip card comprises a housing defining a receiving slot configured for receiving a chip card therein; a stop cushion for assembly in the receiving slot for resisting against the chip card to restrict movement of the chip card in the receiving slot. The chip card can avoid moving in the receiving slot and enhance the stability of portable electronic devices.

## Background
BACKGROUND
1. Technical field
The present disclosure relates to chip card holders and, particularly, to a chip card holder used in a portable electronic device.
2. Description of Related Art
Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are widely used. The portable electronic devices typically use a chip card (e.g., SIM card) for storing information. Chip card holders hold/secure the chip card within the portable electronic devices.
In use, a chip card is mounted into the receiving slot. A battery is placed in a chamber and resists against the chip card, thereby preventing the chip card from moving out from the receiving slot.
However, different batteries may have even tiny differences in size. When a relatively smaller sized battery is placed into the chamber, the battery may not resist against the chip card tightly enough. This results in movement of the chip card in the receiving slot. Such movements may cause poor electrical connection to a connector of the portable electronic device, and thus call quality thereof is reduced. In addition, the battery may hit the chip card when the portable electronic device is heavily shocked or vibrated. Thus, the chip card can be damaged by movements of the battery.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EMBODIMENTS
The chip card holder of the present embodiment is suitable for portable electronic devices, such as, mobile phones, PDAs (personal digital assistants), palm computers and other devices which incorporate a chip card and a battery. FIG. 1 shows a first exemplary chip card holder 100 used to hold a chip card 10. The chip card holder 100 includes a housing 30, a stop cushion 50 detachably assembled in the housing 30 and a cover 70 latching to the housing 30.
The housing 30 is often a part of a portable electronic device for receiving electronic components of the portable electronic device. The housing 30 has a top surface 301, a chamber 31, and a receiving slot 32. The chamber 31 and the receiving slot 32 both are recessed in the top surface 301 and adjacent to each other. The chamber 31 is enclosed by four sidewalls 310 and a bottom wall 312, and receives a battery 90. The receiving slot 32 receives the chip card 10 and the stop cushion 50. The receiving slot 32 has an opening 321 defined in a sidewall 310, thereby communicating the chamber 31 with the receiving slot 32. A locating chamber 33 is defined both adjacent to and communicates with the chamber 31 and the receiving slot 32. The locating chamber 33 is used to locate the stop cushion 50.
The stop cushion 50 is L-shaped and can be made of fabric, rubber, or other resilient materials configured for buffering impact between the battery 90 and the chip card 10. The stop cushion 50 includes a main body 51 and a position portion 52 extending from an end of the main body 51. The position portion 52 can be received in the locating chamber 33 and is configured for latching the main body 51 into the receiving slot 32.
The cover 70 is a battery cover of the portable electronic device. The cover 70 is configured to be detachably mounted to the top surface 301 of the housing 30, and covers at least the battery 90 and the chip card 10.
Referring to FIG. 2, in use, the chip card 10 is placed into the receiving slot 32. The position portion 52 and the main body 51 are respectively inserted into the locating chamber 33 and the receiving slot 32 to block the opening 321 of the receiving slot 32. The main body 51 resists against the chip card 10 to tightly secure the chip card 10 in the receiving slot 32. The battery 90 is placed into the chamber 31 and resists against the stop cushion 50 to prevent the cushion 50 from moving out from the receiving slot 32. The cover 70 latches to the housing 30 for fixing the chip card 10 and the battery 90 in the portable electronic device.
Since the stop cushion 50 is made of resilient materials, even a battery 90 relative small in size can be mounted into the chamber 33 and rightly resist against the stop cushion 50 to retain the chip card 10 in the receiving slot 32, the chip card 10 still can be tightly retained in the receiving slot 32 under the resilient force of the stop cushion 50. In addition, the stop cushion 50 can protect the chip card 10 from impact of the battery 90 when the portable electronic device is heavily shocked/vibrated.
FIG. 3 shows a second exemplary embodiment of a stop cushion 60 detached from the housing 30. The stop cushion 60 can be made of fabric, rubber, or other resilient materials configured for buffering impact between the battery 90 and the chip card 10. The stop cushion 60 includes a main body 61, a position portion 62, and two buffer portions 63. The position portion 62 extends from an end of the main body 61, thereby the position portion 62 and the main body 61 form a L-shaped structure. The position portion 62 is configured to be received in the locating chamber 33 to latch the main body 61 in the receiving slot 32. The buffer portions 63 are respectively positioned at two opposite ends of the main body 61. When the main body 61 latches into the receiving slot 32, the buffer portions 63 resist against the sidewalls 310.
Referring to FIG. 4 together, in use, the chip card 10 is placed into the receiving slot 32. The position portion 62 is inserted into the locating chamber 33 and the receiving slot 32 to block the opening 321 of the receiving slot 32. Meanwhile, the buffer portions 63 approach the sidewalls 310. The battery 90 is placed in the chamber 31 resists against the buffer portions 63 to preventing the cushion 50 moving out from the receiving slot 32. The cover 70 latches to the cover 30 for fixing the chip card 10 and the battery 90 in the portable electronic device.
Referring to FIG. 5, it is to be understood, the buffer portions 63 can combine into one buffer portion 630. Namely, the buffer portion 630 perpendicularly extends from the main body 61.
It is to be understood that the locating chamber 33 and the position portion 52 can be omitted. Accordingly, the stop cushion 50 can be fixed in the receiving slot 32 by glue.
It is to be understood, however, that even through numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of sections within the principles of the invention to the full extent indicated by the broad general meaning of the terms, in which the appended claims are expressed.
