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.

Description:
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.
