The first baffle 41 is parallel with and spaced from the second baffle 42. The third baffle 43 and the fourth baffle 44 are connected between edges of the first baffle 41 and the second baffle 42. A first end of the third baffle 43 is connected with an end of the fourth baffle 44. In the embodiment, the third baffle 43 is substantially perpendicular to the fourth baffle 44. The first baffle 41, the second baffle 42, the third baffle 43 and the fourth cooperatively form a first guiding groove 45. The shaft 90a is located on a lateral surface of the fourth baffle 44 and away from the third baffle 43.
FIG. 6 illustrates that the third baffle 43 of the first door 40 is V-shaped. The third baffle 43 includes a first plate 431 and a second plate 432. The first plate 431 is connected with the second plate 432, and the first plate 431 defines an angle with the second plate 432 to form a bent portion 433 protruding towards the opening 11 when the first door 40 closes the opening 11. The first plate 431 is located between the fourth baffle 44 and the second plate 432. A first protrusion 46 protrudes in an extending direction of the second plate 432 of the first door 40. In the embodiment, the first protrusion 46 is a pole or pillar-like mechanism.
FIG. 3 illustrates that the first elastic member 70 is a torsion spring. The first elastic member 70 includes a first section 71 and a second section 72 formed integrally with each other. An elastic hole 73 is defined where the first section 71 connects to the second section 72. The shaft 90a passes through the elastic hole 73, positioning the elastic member 70 on the first door 40.
FIG. 5 illustrates a structure of the second door 50. The structure of the second door 50 is substantially same as the structure of the first door 40. The second door 50 also includes a first baffle 51, a second baffle 52, a third baffle 53, a fourth baffle 54, a second elastic member 80 (shown in FIG. 2 or FIG. 3), and a shaft 90b. The first baffle 51, the second baffle 52, the third baffle 53 and the fourth baffle 54 cooperatively form a second guiding groove 55. FIG. 6 illustrates that the third baffle 53 includes a first plate 531 and a second plate 532. The first plate 531 is connected with the second plate 532, and the first plate 531 defines an angle with the second plate 532 to form a bent portion 533 protruding towards the opening 11. FIG. 3 illustrates that the second elastic member 80 includes a first section 81 and a second section 82, an elastic hole 83 is defined where the first section 81 connects the second section 82, the shaft 90b passes through the elastic hole 83 to position the elastic member 80 on the second door 50. A second protrusion 56 protrudes in an extending direction of the second plate 532 of the second door 50. The difference between the first door 40 and the second door 50 is that a gap 561 is defined in the second protrusion 56 for engaging with the first protrusion 46.
FIG. 2 illustrates when in assembly, the shaft 90a is passed through the shaft hole 151 and elastic hole 73 positioning the first elastic member 70 and rotatably fixing the first door 40 to housing 10. The first section 71 is received in the through hole 1711, and the second section 72 is stopped against the lateral surface of the fourth plate 44. Therefore, when the first door 40 is rotated to open the opening 11, the first elastic member 70 is compressed to generate an elastic force to drive the first door 40 to rotate to close the opening 11. An installation of the second door 50 is the same as the installation of the first door 40 described above. When the first door 40 and the second door 50 close the opening 11, the second plate 432 of first door 40 makes contact with the second plate 532 of the second door 50, the first protrusion 46 passes through the gap 561, and edges of the first baffle 41, 51, second baffle 42, 52 and the third baffle 43, 53 abut against the housing 10, which prevents dust or ash from contaminating the housing 10 to shorten the lifetime of the electronic members.
FIGS. 7 and 8 illustrate that when the memory card 60 is to be inserted into the housing 10 through the opening 11, the first door 40 and the second door 50 is forced to rotate in opposite directions to open the opening 11, the first protrusion 46 and the second protrusion 56 stop at the signal connector 30, the first elastic member 70 and the second elastic member 80 are compressed, and the memory card 60 is located between the doors 40, 50. Because the long axes of the shaft holes 151, 161 are parallel with the first line, when the memory card 60 makes contact with the first door 40 and the second door 50, the memory card 60 can force the first door 40 and the second door 50 to move along the first line moving the memory card 60 in the opening 11 along the first line. In this state, the first guiding groove 45 and the second guiding groove 55 communicate with the opening 11 and the signal connector 30, and the memory card 60 is received and supported in the first guiding groove 45 and the second guiding groove 55. The memory card 60 slides along the first guiding groove 45 and the second guiding groove 55 and is inserted into the signal connector 30 accurately with a guiding of the first guiding groove 45 and the second guiding groove 55. When the memory card 60 is removed from the housing 10, the elastic force drives the first door 40 and the second door 50 to rotate to close the opening 11.
In the embodiment, when the memory card 60 is inserted into the housing 10, the first door 40 and the second door 50 are forced to rotate to open the opening 11, the memory card 60 is received in and supported in the first guiding groove 45 and the second guiding groove 55, which allows the memory card 60 to be inserted into the signal connector 30 accurately; when the memory card 60 is removed from the housing 10, the elastic force drives the first door 40 and the second door 50 to automatically rotate closing the opening 11, which prevents contaminants from getting into the housing 10 and affecting the performance of the electronic device 100.
Many details are often found in the art such as the other features of a shielding plate. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
