BACKGROUND

1. Technical Field

The present disclosure relates to electronic devices, and particularly to portable electronic devices with chip card holders.

2. Description of Related Art

A dual-SIM capable mobile terminal uses one or two SIM cards. A dual-SIM mobile terminal with two SIM cards can switch between SIM cards according to a user selection. A dual-SIM mobile terminal with two SIM cards can also be used with two different phone numbers.

Typical chip card holders define two side-by-side receiving spaces for receiving the SIM cards, Side-by-side grooves, however, occupy a large area of the mobile terminal.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIGS. 1 to 3 show an exemplary embodiment an electronic device 100, such as a cellular phone or any electronic device using a chip card. The electronic device 100 includes a housing 10, a chip card holder 20, a first retaining board 40, a second retaining board 50, a first electrical connector 42 and a second electrical connector 52.

The housing includes a main body 12 and a retaining board 14 located on the main body 12.

The chip card holder 20 is attached to the housing 10. Two chip cards 30 can be simultaneously attached to the chip card holder 20. The chip card holder 20 includes a base 22, a drawer 24 and a cabinet 26. The cabinet 26 is defined in the base 22, in which the drawer 24 is received.

The base 22 may be a portion of the housing 10 or a separate element fixed to the housing 10. In this exemplary embodiment, the base 22 is a portion of the housing 10.

The drawer 24 includes a first surface 242, a second surface 243 spaced apart from the first surface 242, two opposite sidewalls 244, a first end 246 and a second end 248 spaced apart from the first end 246. The first surface 242 and the second surface 243 each define a receiving space 2422, in which one of the chip or flash cards 30 is received. Two limiting blocks 2442 protrudes from the sidewalls 244. In this exemplary embodiment, the limiting blocks 2442 are located near the second end 248. A cutout 2462 is defined at the first end 246 and communicates with the receiving spaces 2422 and can be used to facilitate removal of the chips cards 30 from the drawer 24 in the situation where the drawer 24 is completely removed from the cabinet 26.

The cabinet 26 includes a receiving compartment 262 and two limiting grooves 264. The drawer 24 is slidably received in the receiving compartment 262. The limiting grooves 264 are located at two sides of the receiving compartment 262 and communicate with the receiving compartment 262. Each limiting block 2442 is slidably received in one of the limiting grooves 264, to limit an inward maximum movement of the drawer 24, when sliding relative to the base 22. While in the current exemplary embodiment, the drawer 24 can be completely removed from the cabinet 26, in other embodiments, there may be additional structure that prevents complete removal of the drawer 24 and limits it outward maximum movement.

The chip cards 30 may both be subscriber identity modules (SIM) card or memory cards; or one of the chip cards 30 is SIM card, the other chip card 30 is memory cards.

Referring to FIG. 7, the first retaining board 40 is for retaining the first electrical connector 42. The second retaining board 50 is for retaining the second electrical connector 52. The first retaining board 40 and the second retaining board 50 are spaced from each other, so a receptacle 16 is formed between the first retaining board 40 and the second retaining board 50. In other words, the first retaining board 40 and the second retaining board act as upper and lower sidewalls of the receptacle 16. The receptacle 16 is for receiving drawer 26 and the chip cards 30. In this exemplary embodiment, the first retaining board 40 is a first circuit board attached to the retaining board 14, the second retaining board 50 is a second circuit board attached to the main body 12. It is to be understood that, one of the first retaining board 40 and the second retaining board 50 may be a circuit board of the electrical device 100, with the other retaining board just being a plain plastic board.

The first electrical connector 42 is attached to a surface of the first retaining board 40 facing the second retaining board 50. The second electrical connector 52 is attached to a surface of the second retaining board 50 facing the first retaining board 40. The first electrical connector 42 is electrically connected to one of the chip cards 30, the second electrical connector 52 is electrically connected to the other chip card 30. In this exemplary embodiment, the first electrical connector 42 faces the second electrical connector 52.

Furthermore, the chip card holder 20 further includes a cover 28 covering the drawer 24 and detachably fixed to the base 22 so the drawer 24 is steadily fixed in the cabinet 26. In this exemplary embodiment, the cover 28 is substantially U-shaped, and includes a main body 282 and two latching portions 284 protruding from opposite ends of the main body 282. Each latching portion 284 includes a latching block 2842. The base 22 defines a slot 222 for accommodating the cover 28. The base 22 further defines two latching grooves 224. Each latching block 2842 is latched in one of the latching groove 224 so the cover 28 is latched in the slot 222 and the main body 282 presses the drawer 24 in the cabinet 26.

Referring to FIGS. 4 to 7, in use, the latching blocks 2842 are released from the latching grooves 224. The cover 28 is detached from the housing 10. The drawer 24 is slid out of the cabinet 26, either partially or entirely, as mentioned above. The chip cards 30 are put into the receiving spaces 2422. The drawer 24 is slid into the receiving compartment 262 of the cabinet 26 until the limiting blocks 2442 are limited in the limiting grooves 264. At this time, the chip cards 30 are retained in the receptacle 16, and respectively retained and electrically connected with the first connector 42 and the second connector 52, thereby putting the chip cards 30 in the electronic device 100.

In above chip card holder 20, the drawer 24 can be completely or partially slid out of the cabinet 26 to expose it from the base 22, thereby facilitating grasping chip cards 30 out of the receiving spaces 2422 or putting the chip cards 30 in the receiving spaces 2422. Additionally, the receiving spaces 2422 are arranged in a stack, and the first electrical connector 42 and the second electrical connector 52 are respectively located on the first retaining board 40 and the second retaining board 50, i.e., the opposite sidewalls of the receptacle 16, thereby reducing the area occupied by the chip card holder 20.

Although numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
