Referring to Fig. 5, it is a cross-sectional view of the member 127 according to another embodiment being engaged with the external connector 3. This embodiment is substantially the same as the fourth embodiment of the bicycle, except that the external connector 3 is inserted into the member 127. Therefore, the inner edge hole _2 of the electroelastic body 1 is sheathed outside the member 127, so that the connector 3 and the member 127 are connected to each other, and the external connector 3 does not contact the compact structure 130, so the original Both the secret service and the electric shielding effect have been bribed. Referring to Figure 6, there is shown a cross-sectional view of the member m in accordance with still another embodiment engaged with the external connector 3. With respect to the fifth embodiment, in the present embodiment, the conductive elastic annular body of the sealing structure (10)! The move did not cover the member 127. Since the external connecting member 3 is inserted into the member 127, the member 127 has a second opening, facing the inner edge hole 13022, wherein the conductive elastic annular body (10) covers a portion of the second opening 1272; wherein the member 127 and the external connecting member 3 The articulation is represented by a section. The substructure is not drawn to simplify the drawing. In the external connector 3 into ==:!

The second brother opens the 1272 size to allow the conductive elastic ring 1302 to be picked up 1272' = elastic ring The body suit just contacts the second opening of the member 127 to maintain contact without being over-squeezed into the member 127. In the former structure, the conductive axis recording can be further increased with the second 127 degrees, which is also helpful for the 127 buckle effect. Please refer to the front view of the conductive elastic ring body according to an embodiment. With respect to the conductive elastic annular body 1302 in FIG. 6, the conductive elastic annular body 3 further includes a plurality of covering surface faces extending from the edge of the inner edge hole 13032 toward the center of the inner edge hole (10) 2, that is, the conductive elastic annular body 1303 The structure is a structure in which the conductive elastic annular body (10) extends from the smudged brain to form a cover sheet, so that the conductive elastic annular body 13〇3 will cover the second opening 1272 by the cover sheet. The area is to improve the dustproof capacity of the member 丨27. In the foregoing embodiments, the conductive elastic annular bladders (10) are always in contact with the members i26, a?, but the present invention is not limited thereto. Please refer to FIG. 8 and FIG. 9. FIG. 8 is a schematic cross-sectional view of an electronic device according to another preferred embodiment of the present invention, and FIG. 9 is a conductive elastic annular body i3i2 of the sealing structure 131 of FIG. The front view. In the present implementation, (4) The structure (3) of the guide _ shape (3) 2 material electroelastic ring body blue structure oil, but the conductive body (3) 2 is condensed in the shell (2), but does not contact the member 127, so the conductive elasticity can be reduced The problem that the covering piece of the annular body i3i2 is squeezed into the component field. Therefore, the length of the cover sheet my extending from the conductive elastic annular body 1-312 to the hole 13122 may be longer than the length of the conductive sheet of the conductive heterocyclic one-stage covering sheet 13034, and even close to the entire first opening 1224. Dust and EMI, ESD effects. Similarly, when the #outer connector 3 enters the first opening 1224, the cover sheet 13034 is bent by the outer connector 3, but based on the elasticity of the conductive elastic annular body 1312, it is opposite to the slit 128 (the area indicated by the broken line is 8) still retains a good cover effect, in which the external connector 3 is connected to the member 127 9 M425309, which is shown in the 8th fiscal, and the rider (10) 4 is also shown in dotted line. 8 in the picture. It should be noted that this structural configuration can also be applied to the member 126, and will not be described again. Please refer to Fig. 10, which is a schematic diagram of an optical disk drive 5 according to another preferred embodiment of the present invention. The optical disk drive 5 includes a casing 52 and a tray 54 which are fed into and out of the casing 52 via a disk opening 522 of the body 52 (shown in phantom in the first drawing). Due to the design of the telescopic mechanism of the conventional tray 54, when the tray 54 is retracted into the casing 52, it is difficult to completely close the tray 54 and the disc opening 522 to leave a gap. Therefore, in the present embodiment, the optical disc drive 5 further includes a conductive elastic annular body % having a through hole sleeved on the carrier plate 542 of the tray 54 and attached to the cover 544 of the tray 54. Therefore, when the tray 54 is retracted into the casing 52, the slit is filled by the conductive elastic annular body 56, thereby achieving the effect of sealing the casing 52. Further, when both the casing 52 and the cover 544 are electrically conductive, the conductive elastic annular body 56 contributes to the dustproof and electric shielding effect of the entire optical disk drive 5. As described in the previous embodiments, the present invention utilizes the elasticity of the conductive elastic annular body of the sealing structure to effectively cover the gap between the electrical connector or other components in the electronic device and the housing to improve the dustproof capability of the electronic device. Moreover, the conductivity of the conductive elastic annular body of the sealing structure is utilized to increase the anti-electromagnetic interference and anti-static effect of the housing, and the prior art cannot effectively overcome the problem that the gap between the electrical connector and the housing is difficult to seal. In addition, the conductive elastic annular bodies of the foregoing embodiments are all disposed on the inner side of the casing as an example, but the present invention is not limited thereto. In practice, the conductive elastic annular body must be directly fixed to the outside of the casing, and the effect of the creation can still be achieved. In addition, compared with the prior art, the sealing structure of the present invention is thinner, which also contributes to the reduction of the volume of the casing.
