1. Technical Field
Embodiments of the present disclosure relate to electronic card connectors, and particularly to an electronic card connector having a tray assembly and an electronic device using the electronic card connector.
2. Description of Related Art
Some electronic devices have electronic cards, such as a Subscriber Identity Module (SIM) card or a flash memory card, installed in a sidewall of the electronic device. However, when the electronic device requires a dedicated tool to eject the electronic card out of the sidewall, it is inconvenient for a user to carry and use the dedicated tool.
All the views are schematic.
The disclosure, including the accompanying drawings in which like reference numerals indicate similar elements, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”

The baffle portion 141 includes an inner surface 1410, an outer surface 1411, and a bottom surface 1412. A sunk portion 1413 is defined in the outer surface 1411, and two strip through holes 1414 are defined in a bottom of the sunk portion 1413. The two strip through holes 1414 are on a same level and extend along a direction substantially parallel to the bottom surface 1412. The flat portion 140 is connected to the inner surface 1410 of the baffle portion 141 and is located adjacent to the two strip through holes 1414, and the lower surface 1402 is coplanar with the bottom surface 1412.
Each locking rod 15 includes a body 151, a head 152 at one end of the body 151, and a hook 153 at an opposite end of the body 151. The head 152 is received in the sunk portion 1413. The head 152 is a substantially rectangular tab and is angled with respect to the body 151. The hook 153 is angled with respect to the body 151. The body 151 defines an oblique groove 154. A through hole 155 is defined in the bottom of the oblique groove 154. A depth of the oblique groove 154 is substantially half the size of a thickness of the locking rod 15. Two fixing pins 156 protrude from opposite sides of the body 151. One of the two fixing pins 156 is adjacent to the hook 153, and the other fixing pin 156 is adjacent to the head 152. The fixing pin 156 adjacent to the head 152 and the head 152 extend away from a same side of the body 151. The fixing pin 156 adjacent to the hook 153 and the hook 153 extend away from opposite sides of the body 151.
The base 2 includes a fixing body 21, an elastic member 22, and a number of fastening components 23. The fixing body 21 is fixed to a bottom of the electronic device 10 by the fastening components 23. The fixing body 21 defines a substantially rectangular receiving cavity 211 that receives the tray assembly 1. An open end of the receiving cavity 211 faces the slot 13. Two hook-receiving cavities 2111 are defined in a top surface of the fixing body 21. The hook-receiving cavities 2111 communicate with the receiving cavity 211. In the illustrated embodiment, the two hook-receiving cavities 2111 are defined in opposite bottom corners of the receiving cavity 211, and each of the two hook-receiving cavities 2111 is similarly angled with respect to a corresponding sidewall of the receiving cavity 211. The elastic member 22 is arranged at a bottom surface of the receiving cavity 211 and includes an arcuate portion 221 protruding toward the open end of the cavity 211.
In assembly of the tray assembly 1, the two locking rods 15 are inserted through the two strip through holes 1414, intersected and overlapped with each other by the two oblique grooves 154. When the two locking rods 15 are overlapped, the overlapped portions are on the same level as the non-overlapped portions and the two through holes 155 of the locking rods 15 overlap each other. The hooks 153 of the two locking rods 15 are received in a corresponding hook-receiving cavity 2111, and the two heads 152 are received in the sunk portion 1413. The two heads 152 are flush with the outer surface 1411 and spaced a distance from the bottom of the sunk portion 1413. The pivot 16 is received in the two overlapped through holes 155 and the pivot through hole 1403, thereby rotatably connecting the two locking rods 15 to the sliding tray 14. One of the two elastic components 17 is connected between the two fixing pins 156 adjacent to the hooks 153, while the other elastic component 17 is connected between the two fixing pins 156 adjacent to the head 152. The two elastic components 17 are partially received in a corresponding recess 1404. The two elastic components 17 apply a pushing force to the two locking rods 15. The support member 18 includes an open bottom slot 181. The support member 18 covers the electronic card-receiving recessed portion 1405, such that the open bottom slot 181 faces the card-receiving recessed portion 1405. The electronic card 19 is received in the open bottom slot 181. In the illustrated embodiment, the two elastic components 17 are springs.

To release the tray assembly 1 from the base 2, the two heads 152 are pushed toward each other, thereby causing the two locking rods 15 to rotate about the pivot 16. The two hooks 153 then move toward each other to release from the two hook-receiving cavities 2111. The tray assembly 1 is then ejected partially out of the electronic device 10 by the compressed elastic member 22 and can be pulled out of the electronic device 10.
Although certain inventive embodiments have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present embodiments without departing from the scope and spirit of the present disclosure.
