BACKGROUND OF THE INVENTION [0001]1. Field of the Invention [0002]The present invention relates to shielding members, and more particularly, to a shield member for covering a slot of an electronic device. [0003]2. Description of Related Art [0004]The primary function of an industrial server is to store massive data therein, and the hardware thereof is generally carried by carriers to be plugged into a plurality of slots of the server by way of hot swap. [0005]Referring to FIG. 1, a server 1 having a plurality of slots 10 for receiving hard disk carriers 11 therein is illustrated, in which unused slots 10 are covered by a shield member 12 for shielding the slots from dust and electromagnetic interference. Users may choose among different manufacturers the appropriate servers having a sufficient number of slots that suit to their needs; on the other hand, spare slots are often reserved for emergency use and convenient replacement in the case of an electric breakdown of the slots in use. [0006]As shown in the drawing, a slide block 120 is provided at an outer edge of the shield member 12 corresponding to the slot 10 to enable the shield member 12 to be slidably disposed in the slot 10; a plurality of stopping tabs 13 is disposed at the front of the slot 10 of the server 1, the shield member 12 also including connecting tabs 125 that abut against an outer wall of the stopping tabs 13 to position and meet the insertion depth of the shield member 12 in the slot 10. A handle 121 is axially provided as well as a set of block bodies 122 that are elastically disposed on the front of the shield member 12; block bodies 122 are disposed on one end of the handle 121 while a wedge 123 is disposed on the other end thereof that abuts against an inner wall of stopping tabs 13 by the assembly of the handle 121 and block bodies 122 and, works in conjunction with the connecting tab 125, is to be stopped by an outer edge of the stopping tabs 13 to thereby fix the shield member 12 in the slot 10. [0007]However, in the foregoing structure, there exists a drawback of the insufficient coupling between the shield member 12 and the slot 10 by the slide block 120 in that the slide block does not have the flexibility required to be tightly abut against the wall of the slot 10, resulting in a common difference of coupling between the two. In order to more securely plug the shield member in the slot 10, it is required to increase the length of at least one side of the shield member 12 to allow more slide blocks 120 to be disposed thereon, which undesirably necessitates the use of more material to fabricate slide blocks 120. And, even if the length of the shield member 12 is increased and more slide blocks 120 are disposed thereon, there still exists a gap between the shield member 12 and the wall of the slot such that when exerting force on the shield member 12 for insertion, the shield member tends to get stuck due to uneven pressure exerted thereon and cannot be smoothly inserted in the groove. [0008]Moreover, the length of the hard disk carrier 11 is made to comply with the depth of the slot 10 after pushing the hard disk carrier 11 toward the slot 10 to electrically connect the server 1 and secure the hard disk carrier 11 in the groove 10; however, because of the consideration of costs, the length of the shield member 12 is often designed and made shorter than the depth of the slot 10, as a consequence, the connecting tab 125 becomes an sole means for connecting the stopping protrusions 100 in order to position the shield member in the slot, yet such a approach often causes the connecting tab 125 to disengage from the stopping protrusion 13 because of the problem of getting stuck caused by uneven pressure as mentioned above. [0009]Therefore, it is desirable to develop a novel mechanism capable of improving on the drawbacks of prior arts. SUMMARY OF THE INVENTION [0010]The present invention aims to eliminate the aforementioned drawbacks, and, as such, a primary objective of the present invention is to provide a shield member having a relatively shorter length and smaller size that helps to reduce the material cost. [0011]Another objective of the present invention is to provide a shield member that can be fittingly inserted in the slot of an electronic device and prevented from getting stuck to facilitate smooth insertion. [0012]Another objective of the present invention is to provide a shield member that can be securely positioned to meet the depth of the slot of an electronic device. [0013]In order to achieve the above and other objectives, the present invention provides a shield member for covering the slot of an electronic device, including at least a body for inserting and pluggable into the slot; a slide block disposed on the surface of the body and corresponding to the slot; and an elastic portion disposed on the surface of the slide block and elastically contacting the wall of the slot for the body to be tightly inserted into the slot [0014]In contrast to prior techniques that necessitates increasing the length of the shield member so that more slide blocks can be disposed thereon, the shield member of the invention employs an elastic portion thereof that elastically contacts the wall of the slot so as to be smoothly and tightly inserted in the slot, thereby reducing the length thereof and the material cost as a result. [0015]The elastic portion is tightly inserted into the slot along with the insertion of the body in the slot of the electronic device, which eliminates a problem of getting stuck caused by the swing insertion due to the uneven pressure exerted thereto. [0016]The slot of the electronic device is provided with a first connecting tab and a second connecting tab is disposed on a side surface of the body that corresponds to an outer edge of the first connecting tab, thereby positioning to meet the insertion depth of the shield member in the slot, which ensures that the shield member does not get stuck in the slot by using its elastic portion to enable the second connecting tab thereof to connect and abut against the first connecting tab, thereby overcoming the drawback of disengagement from one another as occurred in the prior art. [0017]Further, the shield member of the invention can include a plurality of third connecting tabs to connect and abut against an existing structure provided in the slot when the body is inserted into the slot, thereby enforcing the insertion and spreading the pressure exerted to the first connecting tab. The present invention offers advantages over the prior art techniques as it has been proved to easily pass the drop tests and have industrial applicability.
