FIELD OF THE INVENTION  
       [0001]     The present invention is related to a dust cover, and more particularly, to a dust cover having a receptacle for exchangeably receiving a label.  
       BACKGROUND OF THE INVENTION  
       [0002]     Internet equipments are broadly used in a modem office. The way to equip the internet equipments is usually to dispose the internet cable along the floor so as to make the environment neat and clean. Therefore, the cable socket is usually disposed on the lower part of the cubical wall in the office and near the floor. However, the floor almost always has the dust falling thereon, and the dust is easily to be stirred by foots. Therefore, the socket needs a dust cover to prevent the dust from flowing into the socket and resulting in a disconnection between the socket and the plug. Although the dust does not suddenly block the electrical connection between the socket and plug, it may interfere the transmission therebetween and decrease the quality of the network.  
         [0003]     Furthermore, the internet equipments are also broadly used in a hotel room. The socket is usually disposed beside the dressing table or also near the floor. When the house cleaner cleans the room, the cleanser may be spattered into the socket and the metal terminal therein will be etched. Beside, the sockets in the ordinary residence are also disposed near the floor. So, the some problems still exist. Furthermore, a child usually has a curiosity to touch every thing he can touch, so the socket will be the object of his and the socket will be damaged by the child or the child will be hurt by the socket. On the other hand, the socket might become a nesting place of a laying spot for bugs or pests, which might damage the socket as well. For preventing those problems described above, usually a dust cover is disposed on the socket.  
         [0004]     Please refer to  FIG. 1 .  FIG. 1  is a schematic view showing a conventional dust cover. The dust cover  1  has a board  10  and two holders  11 . The socket  2  has a body  20 , two locking aperture  21 , and a plugging hole  23 . The function of the conventional dust cover  1  is very simple that the board  10  holds on the socket  2  through the connection between the holders  11  and the locking aperture  21 . And the board  10  covers the plugging hole  23  and protects the socket  2  away from dust and pest.  
         [0005]     However, the dust cover  1  in  FIG. 1  still has drawback. That is, while once the dust cover  1  is removed, it is very easy to be lost owing to its small volume. Then it becomes necessary to buy a new dust cover  1 .  
         [0006]     Please refer to  FIG. 2  and  FIG. 3 .  FIGS. 2 and 3  are schematic views of another conventional dust cover. The dust cover  3  has the fixed portion  33 , movable portion  30 , a plurality of holders  31 , and a protruding locker  32  with a incline  32   a  thereon. The protruding locker  32  is plugged into the slot  25  of the socket  2  and the incline  32   a  is engaged into the cavity  25   a  for holding the movable portion  30  covering the plugging hole  23 . The biggest difference between the dust cover  3  and the dust cover  1  in  FIG. 1  is that in the dust cover  3  of  FIG. 3 , the movable portion  30  and the fixed portion  33  is separated by the bending slot  35 . Because the material at the bending slot  35  is thinner, when the external force applied to the movable portion  30 , the dust cover  3  will be bended along the bending slot  35  and creates a bending line  37 . Therefore, in  FIG. 3 , while the movable portion  30  is bended, the plugging hole  23  is uncovered and the connecting portion  40  of the plug  4  is inserted into the plugging hole  23 , and the elastic plate  41  slides into the slot  25  for forming a combination between the combining incline  41 a and the cavity  25   a.  Meanwhile, the fixed portion  33  is still fixed to the locking hole  21  of the socket  2 . Therefore, there is no need to worry about that the dust cover  3  might be missing. When the plug  4  is pulled out of the socket  2 , the movable portion  30  is moved back to cover the plugging hole  23 .  
         [0007]     Although the conventional dust cover  3  shown in  FIG. 2  and  FIG. 3  is better in some ways, it still has some drawback needed to be improved. For identifying the socket, a label usually is disposed on the socket. In the past, a label is stuck around the socket. However, the label is unable to be moved together with the socket. Therefore, the most common way to label the socket is to stick the label  39   a  directly on the surface  39  of the dust cover  30 . But it still has a drawback because the label  39   a  is not easily exchangeable or easily being torn down. Furthermore, the strength of the glue on the label  39   a  will gradually decrease till the label  39   a  falls after a period of time.  
         [0008]     The above-mentioned disadvantages of the conventional dust cover needs to be resolved. So, it is desired to have a dust cover having a structure with an exchangeable label but without a paster label.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0046]     The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of the invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.  
         [0047]     The present invention will now be described more specifically with reference to the following embodiments. Please refer to  FIG. 4-1  and  FIG. 4-2 .  FIG. 4-1  is a front view and  FIG. 4-2  is a back view, showing the dust cover according to a preferred embodiment of the present invention. The dust cover  5  includes a fixed portion  53  and a movable portion  50 . The flexible portion  57  connects the fixed portion  53  with the movable portion  50 . In the embodiment shown in  FIG. 4-1  and  FIG. 4-2 , the flexible portion  57  is defined by the recess slot  55  and formed integrally with the fixed portion  53  and the movable portion  50 . According to  FIG. 4-2 , the recess slot  55  is formed and being recess towards three directions, two lateral sides. Because the thickness of the recess slot  55  is relatively much thinner than the thickness of the fixed portion  53  and the movable portion  50 , when the external force applied to the movable portion  50 , the flexible portion  57  will be bended. Therefore, the plugging hole is uncovered (please refer to  FIG. 3 ). According to the  FIG. 4-1 , the present invention further has a receptacle  59  for exchangeablely receiving the label therein. Accordingly, the label can be easily replaced by being drawn out from the receptacle  59 . And the drawback in the conventional dust cover that the label is easily torn down can be avoided.  
         [0048]     Please refer to  FIG. 4-2 . The fixed portion  53  further has a fixing block  51  for fixing the fixed portion  53  on the socket  2  ( FIG. 3 ). Furthermore, the movable portion  50  has a protruding element  52  for being inserted into the plugging hole  23  ( FIG. 3 ) so as to keep the movable portion  50  firmly covering the plugging hole  23  and avoiding the dust.  
         [0049]     Please refer to  FIG. 4-1 . The receptacle  59  has a insertion slot  54  for the label  59   a  being inserted therein. Furthermore, for preventing the label  59   a  from slipping out from the receptacle  59  accidentally, a stopper  56  is disposed corresponding to the opening of the insertion slot  54 . Therefore, the label  59   a  will not fall off from the receptacle  59  by accidental external force.  
         [0050]     Please refer to  FIG. 4-3  and  FIG. 4-4 .  FIG. 4-3  is a side view fo the dust cover according to a preferred embodiment of the present invention. And  FIG. 4-4  is a top view of the dust cover according to a preferred embodiment of the present invention. The fixing block  51  and the protruding element  52  are disposed at the back of the dust cover  5  and the receptacle  59  is disposed in front of the dust cover  5 . The flexible portion  57  formed by the recess slot  55  connects the fixed portion  53  with the movable portion  50 . One side of the stopper  56 , which faces to the receptacle  59 , is inclined or an arc for the label  59   a  easily drawn out by a conscious external force.  
         [0051]     Please refer to  FIG. 5 .  FIG. 5  is a schematic view showing the dust cover combined with the socket according to the present invention. The socket  2  has a fixing aperture  21 ′ for fixed the fixing block  51  of the dust cover  5  therein. Certainly, the fixing block  51  can be as same as the holders  31  of the  FIG. 2 , and the fixing aperture  21 ′ also can be as same as the locking hole  21  of the  FIG. 2 . Furthermore, the fixed portion  53  can be stuck, screwed, or welded by the high frequency welding machine when being fixed engaged with the socket  2 .  
         [0052]     Please refer to  FIG. 6 .  FIG. 6  is a schematic view showing the dust cover according to another preferred embodiment of the present invention. The fixed portion  53  has a first pivotal join portion  53 ′, while the movable portion  50  has a second pivotal join portion  55 ′ pivotally connected to the first pivotal join portion  53 ′ through a shaft  57 ′. Therefore, the first pivotal join portion  53 ′, the second pivotal join portion  55 ′ and the shaft  57 ′ have the same functions as the flexible portion  57  described above, and further, the possible breakage near the flexible portion  57  shown in  FIG. 5  can be avoided.  
         [0053]     Please refer to  FIG. 7 .  FIG. 7  is a schematic view showing the dust cover according to yet another preferred embodiment of the present invention.  FIG. 7  shows that a socket  6  having a dust cover  50 ′ thereon. The dust cover  50 ′ is formed integrally with the body  60  of the socket  6 . The socket  6  has a plugging hole  66  for the plug  4  ( FIG. 3 ) plugged therein so as to form an electrical connection. A slot  64  is disposed in the plugging hole  66  and has a cavity  64   a  for being engaged with the incline  41   a.  The dust cover  50 ′ is connected to the body  60  through the connecting portion  57   a.  The connecting portion  57   a  is bendable and the thickness thereof is much thinner than the dust cover  50 ′. Therefore, when the external force is applied, the dust cover  50 ′ will move flexibly away from the plugging hole  66 . The dust cover  50 ′ also has the receptacle  59  as shown in  FIG. 4-1 .  
         [0054]     Please refer to  FIG. 8 .  FIG. 8  is a schematic view showing the dust cover according to still another preferred embodiment of the present invention. The socket  7  has a dust cover  50 ″ directly pivotally connected with the body  70  of the socket  7 , but not through the fixed portion  53  as shown in  FIG. 6 . The body  70  has a pivotal join portion  72  pivotally connected to the shaft  71   a  of the dust cover  50 ″. The socket  7  also has the slot  64  and the cavity  64   a  disposed therein as shown in  FIG. 7 . The usage of the pivotal join portion  72  is to prevent the possible breakage near the connecting portion  57   a.  The dust cover  50 ″ also has the receptacle  59  as shown in  FIG. 4-1 .  
         [0055]     Therefore, it is clear that the receptacle which exchangeablely receives the label therein makes the label exchanging easy and avoid the drawbacks of using the paster label  39   a  ( FIG. 3 ). And the motion mechanism of the movable portion is achieved by the bendable connecting portion or the pivotal join mechanism. Furthermore, the dust cover is able to be formed integrally with the socket and the process of connecting the socket and the dust cover is spared. Thus the efficacy of the dust cover is increased.  
         [0056]     While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
