The main body 30 includes an inner surface 31 and a sidewall 32. A second through hole 320 and a first through hole 321 are defined in the sidewall 32. In the exemplary embodiment, the first through hole 321 is configured for inserting the electronic card, such as, SD card. In another embodiment, the electronic device 1 may be
The connector 50 is set in the inner surface 31 of the main body 30, and is configured for receiving the electronic card 90. The connector 50 includes a support portion 501, a left positioning pole 53, a right positioning pole 54, an axle 55, two torsion springs 56, a salver 57, a groove member 58, and a resuming device 59.
The axle 55 is rotatably connected to the support portion 501 of the connector 50. The axle direction is parallel to the inner surface 31 of the main body 30. The torsion springs 56 are placed over two ends of the axle 55 respectively. Two ends of the torsion spring 56 are fixed to the axle 55 and the support portion 501 respectively.
The salver 57 is slidably connected to the support portion 501 of the connector 50, and includes a spring tab 571 and a plurality of touching terminal (not shown). The spring tab 571 is set in the top surface of the salver 57, and is configured for pressing the inserted electronic card 90 to keep the electronic card 90 fixed. The plurality of the touching terminals is configured for touching metal terminals (not shown) of the electronic card 90 to establish an electronic connection. The groove member 58 is connected to the support portion 501, and is configured for limiting the salver 57 to slide. The resuming device 59 is set in the inner of the connector 50, and includes a key portion 591 and a main body 592. A portion of the key portion 591 is exposed to the second through hole 320. In the exemplary embodiment, the distance between the top surface of the salver 57 and the below edge of the axle 55 is equal to the thickness of the electronic card 90.
When inserting the electronic card 90, user inserts the electronic card 90 to the salver 57 to a predetermined position by the first through hole 321. When the electronic card 90 is completely inserted into the salver 57, the spring tab 571 presses the electronic card 90 to keep the electronic card 90 fixed. During inserting the electronic card 90 into the salver 57, the electronic card 90 drives the axle 55 to rotate, so that, the torsion spring 55 generates an elastic force relative to the electronic card 90.
When rejecting the electronic card 90, user presses the key portion 591 of the resuming device 59, so that, the resuming device 59 moves in a first direction, and when the resuming device 591 moves in a predetermined position and touches the groove member 58, the groove member 58 starts to move in a second direction by a force from the resuming device 59. When the salver 57 separates from the groove member 58, the limitation of the salver 57 is released, so that, the axle 55 starts to rotate by the elastic force from the torsion spring 56. Simultaneously, due to a friction between the electronic card 90 and the top surface of the salver 57, the axle 55 drives the salver 57 together with the electronic card 90 to move towards to the first through hole 321 until the portion of the electronic card 90 is exposed to the first through hole 321. For better understanding the disclosure, the following is a detailed exemplary embodiment.
The support portion 501 includes a left sidewall 51 and a right sidewall 52. Sliding grooves 521, 522 along a transverse direction are formed in the middle portion of the left sidewall 51 and the right sidewall 52 respectively. The sliding grooves 521, 522 are configured for providing a slideway for the salver 57. In the exemplary embodiment, the distance between the side of the sliding groove 521 and the side of the sliding groove 522 is equal to the length of the first through hole 321.
Axle holes 510, 520 are formed in one end of the left sidewall 51 and the right sidewall 52 adjacent to the sidewall 32 respectively. The axle 55 is passed through the axle holes 510, 520 to rotatably connect to the left sidewall 51 and the right sidewall 52. Peristomes 511, 521 are formed in another end of the left sidewall 51 and the right sidewall 52 away from the sidewall 32 respectively.
Receiving holes 530, 540 along a longitudinal direction are defined in the top surface of the left positioning pole 53 and the right positioning pole 54 respectively.
The groove member 58 includes a positioning block 581, a bolt 582, and a spring 583. The positioning block 581 includes a main body 584 and extending portions 585, 586 extending from the same side of two ends of the main body 584. The extending portions 585, 586 cooperate with the inner surface 31 to form two inclined surfaces respectively. Through holes 587, 888 along a longitudinal direction are defined in the extending portions 585, 586.
The salver 57 includes a front portion 572 and a posterior portion 573. A plurality of grooves 574 is formed on the top surface of the posterior portion 573. The extending direction of the grooves 574 is vertical to the left sidewall 51 and the right sidewall 52.
Each of the torsion springs 56 includes an elastic body 561 and an elastic pole 562. The elastic body 561 is placed over the two ends of the axle 55 respectively. One end of the elastic pole 562 is fixed to the axle 55, and another end of the elastic pole 562 is fixed to the left sidewall 51 and the right sidewall 52.
When assembling the electronic device 1, the salver 57 is placed on the sliding grooves 521, 522, so that, the salver 57 is slidably connected to the left sidewall 51 and the right sidewall 52. Secondly, the elastic body 561 of each of the torsion springs 56 is placed over the two ends of the axle 55, and the two ends of the axle 55 are inserted into the axle hole 510, 520, and the elastic poles 562 of each of the torsion springs 56 are fixed to the axle 55 and the left sidewall 51 and the right sidewall 52 respectively, so that, the axle 55 is rotatably connected to the left sidewall 51 and the right sidewall 52. Thirdly, the resuming device 59 is installed inside of the connector 50, and the key portion 591 is exposed to the second through hole 320. Fourthly, the main body 584 of the positioning block 581 of the groove member 58 is placed on the peristomes 511, 521 of the left sidewall 51 and the right sidewall 52, and the through holes 587, 588 are symmetrical to the receiving holes 530, 540 respectively, so that, the groove member 58 is fixed to the left sidewall 51 and the right sidewall 52. Because the main body 584 presses the groove 574 of the salver 57, thereby limiting the salver 57 to slide.
Referring to FIGS. 3-4, when inserting the electronic card 90, user inserts the electronic card 90 into the salver 57 to a predetermined position by the first through hole 321. When the electronic card 90 is completely inserted the salver 57, the spring tab 571 presses the inserted electronic card 90 to keep the electronic card 90 fixed. During inserting the electronic card 90 into the salver 57, the electronic card 90 drives the axle 55 to rotate, so that, the two torsion springs 55 generates an elastic force relative to the electronic card 90.
When rejecting the electronic card 90, user presses the key portion 591 of the resuming device 59, so that, the resuming device 59 moves in a first direction, and when the resuming device 591 moves in a predetermined position, and touches the groove member 58, the groove member 58 starts to move in a second direction by a force from the resuming device 59. When salver 57 separates from the groove member 58, the limitation of the salver 57 is released, so that, the axle 55 starts to rotate by the elastic force from the two torsion springs 56. Simultaneously, due to a friction between the electronic card 90 and the top surface of the salver 57, the axle 55 drives the salver 57 together with the electronic card 90 to move towards to the first through hole 321 until the portion of the electronic card 90 is exposed to the first through hole 321.
After rejecting the electronic card 90, the spring 583 of the groove member 58 resumes elasticity, and drives the groove member 58 to move along a direction adjacent to the groove 574, the inclined surface of the groove member 58 cooperates with the main body 592 of the resuming device 59 to drive the resuming device 59 to move along an axle direction of the first through hole 320 until the resuming device 59 resumes an initial position.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
