1. Field of the Disclosure
The present disclosure relates to an electronic device and, particularly, to an electronic device with a subscriber identification module (SIM) card retention assembly.
2. Description of the Related Art
Nowadays, mobile phones are widely used and have become a part of modern life. Most mobile phones have a SIM card for carrying information which is necessary to operate the mobile phone. The SIM card may also contain personal information for the subscriber, for example, a listing of frequently used telephone numbers. Good electrical contact between the SIM card and the mobile phone is important. Therefore, a SIM card retention assembly is necessary for securing the SIM card in electronic devices such as mobile phones.
Typically, at least one SIM card seat is defined in a main body of the electronic device. A SIM card retention assembly includes a cover disposed above the SIM card seat. The cover and the SIM card seat cooperatively define a space for receiving the SIM card. When the SIM card is inserted into the space between the SIM card seat and the cover, a part of the SIM card is fixed tightly between the SIM card seat and the cover, and another part of the SIM card is exposed for disassembling.
Due the reduced size of the electronic devices and the SIM cards, disassembly of the SIM cards can be problematic. A user may be forced to draw the SIM card out of the SIM card retention assembly with a relatively large force, which increases the risk that the SIM card and the SIM card retention assembly will be damaged.
Therefore, a new electronic device with a SIM card retention assembly is desired to overcome the above-described shortcomings.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views, and all the views are schematic.

The retaining member 41 includes a sheet-like main body 411. The main body 411 includes a mounting surface 4111 facing the bottom surface of the battery groove 13, a top surface 4112 opposite to the mounting surface 4111, and a side surface 4113 connecting the mounting surface 4111 and the top surface 4112. The main body 411 further includes a first protruding portion 413, a second protruding portion 415 and a third protruding portion 417 each extending from the side surface 4113. The first protruding portion 413 extends from a middle portion of the side surface 4113. The second protruding portion 415 extends from an end of the side surface 4113. The third protruding portion 417 extends from another end of the side surface 4113. Thus, the first, second, and third protruding portions 413, 415, 417 and the side surface of the main body 411 cooperatively define two cutouts 46, 47. The cutouts 46, 47 may have shapes according to shapes of an end of two SIM card seats 15 away from the arcuate depression 151 to allow the SIM cards 30 ingress and egress from the respective SIM card seats 15.
In one embodiment, the retaining member 41 is made of plastic. The retaining member 41 is fixed to the bottom surface of the battery groove 13 by for example, a double-sided adhesive tape (not shown) adjacent to the SIM card seats 15. The main body 411 of the retaining member 41 further defines a receptacle depression 4115 (see
The positioning member 43 may be a resilient member such as a resilient sheet, a spring, and a rubber member. In one embodiment, the positioning member 43 is a metallic resilient sheet. The positioning member 43 defines two mounting holes 431 corresponding to the two fastener columns 4151. A columnar positioning post 433 facing the mounting surface 4111 extends from the positioning member 43. The positioning member 43 is fixed to the retaining member 41 via the fastener columns 4151 passing through the mounting holes 431, for example, by being welded together. In other alternative embodiments, the fastener columns 4151 and mounting holes 431 may be replaced by other fastener members such as a screw and threaded hole structure, or hooking structures.
The rotary member 45 may be a substantially elongated sheet-like member including a first surface 451 and a second surface 452 opposite to the first surface 451. The rotary member 45 further defines a mounting hole 453 in a middle portion of the rotary member 45 corresponding to the protruding column 17, and a positioning hole 454 at an end of the rotary member 45 corresponding to the positioning post 433. The mounting hole 453 is a through hole communicating with the first and second surface 451, 452. The positioning hole 454 can be one of a through hole or a blind hole. In the illustrated embodiment, the positioning hole 354 is a through hole.
The rotary member 45 is fixed between the first main body 10 and the retaining member 41 by passing the protruding column 17 through the mounting hole 453 and the through hole 4131. The rotary member 45 can be rotated relative to the protruding column 17 of the first main body 10 in a horizontal plane.
An end of the rotary member 45 can be moved and fixed to the positioning member 43 by inserting the positioning post 433 into the positioning hole 454, and the other end of the rotary member 45 is inserted into the limiting depression 4171, such that the rotary member 45 is positioned on a middle portion of the two SIM cards 30 tightly, and the SIM cards 30 are secured in the two SIM card seats 15. The positioning post 433 is detachable from the positioning hole 454, so that the end of the rotary member 45 may be pushed into the receptacle depression 4115, thereby exposing the SIM cards 30. Thus, it is very convenient to disassemble the SIM cards 30 from the SIM card seats 15. In addition, the SIM cards 30 and the SIM card retention assembly 40 are not easily damaged.
In the illustrated embodiment, the rotary member 45 may further include a pushing protrusion 455 extending from an edge of the first surface 451 away from the positioning hole 454, and two sliding slots 456 defined in the two opposite edges of the first surface 451 adjacent to the positioning hole 454. The sliding slots 456 are configured to facilitate the positioning post 433 to engage with the positioning hole 454 of the rotary member 45.
It should be pointed out that the first main body 10 may only define a single SIM card seat 15 for receiving one SIM card, and a length of the rotary member 45 of the retention assembly 40 can be changed according to the width of the single SIM card seat 15.
Finally, while the embodiments have been described and illustrated, the disclosure is not to be construed as being limited thereto. Various modifications can be made to the embodiments by those of ordinary skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
