Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a connector device, and especially to a connector device in which a chip card can be plugged in, and has heat dissipating capability. 
         [0003]    2. The Prior Arts 
         [0004]    With the advancement of electronic technologies, conventional methods for business transactions or data transmission ill our daily lives are being more and more developed around electronic technologies, such as the credit card for money transactions, the cash card or electronic purse card, used for paying transportation fares, the IC card for parking fees, the health card having individual health information or personal identification function being stored, the access card, and various kinds of smart card such as for the set-top box for digital television, which have all dramatically changed the conventional habits for carrying cash, personal identifications, and keys, or for watching TV Nowadays, a person can use a chip card to replace the aforementioned conventional habits by directly swiping a chip card instead. Thus, not only much hassle is avoided, but the action to swipe the chip card is accomplished easily and quickly. 
         [0005]    The characteristic of the above chip card is that the chip card includes input/output interface, and memory, and some even have a microprocessor in them. Thus the chip cards have data access control, storage, or even processing functions. The method for data access of these chip cards can be of contacting or non-contacting. For the non--contacting method of reading the chip card, one only requires to bring the chip card near to a reader for completing data transmission process. But for the contacting method for data transmission, the chip card is required to be plugged in or put into a connector device of a card reader device which is electrically connected, thus accomplishing electrical conduction and data transmission. Because the space where the chip card is plugged in or put into is of a confined space, if the number of insertions or readings of the card is too excessive or the duration for reading or inputting the card after it being inserted is too long, the terminal portion being electrically-reach relatively high temperature, especially for the connector of the set-top box for digital TV, on which the chip card is being read continuously when watching TV; therefore, the amount of heat produced from the chip card is quite astounding. Because a preferable heat dissipating structure or device is not disposed on the conventional connector device, the heat buildup from the card because of long usage duration or frequent usage will damage the electronic parts on the reader device with the connector device or damage the chip card being used. As a result, the reader device is prone to suffer from crashes easily or that the chip card functionality would be failed, or at the same time the lifespan of the reader device or the chip card would become shortened. 
       SUMMARY OF THE INVENTION 
       [0006]    To improve upon the disadvantage of having inadequate heat-dissipation ability of the conventional connector, thereby avoiding the reading device of which the connector is disposed on to suffer from crashes or the functionality failures of the chip card, and at the same time, the lifespan of the reader device and the chip card are increased. The present invention provides a connector device having superior beat dissipation function. The heat conduction plate in the present invention can remove the heat buildup in the region surround the connector terminals via conduction or convection produced by the chip card, so that the temperature of the connector can be controlled, and thus the disadvantage of the reduced lifespan of the electronic devices is eliminated. 
         [0007]    To achieve above objective, a connector device provided in the present invention includes an insulator body, a plurality of terminals mounted on the insulator body and each having a contacting portion, respectively, a cover body covered on the insulator body, and the cover body is enclosing the terminals and is formed with a heat dissipating window, which is positioned above the contacting portion, and a heat conduction plate mounted on the cover body and has formed at least one guiding groove concaved toward each heat dissipating window. Furthermore, the material of the heat conduction plate can be aluminum or copper, but it is not limited by to these two kinds of metal, and any other materials having high coefficient of thermal conductivity can be used. Many raised fins can be made to protrude and extend out from the surface of the heat conduction plate, but is not limited to only this structure. In addition, a plurality of guiding grooves can be made, and each guiding groove can be positioned in parallel or corresponding to the contacting portion. 
         [0008]    By means of the heat conduction plate, the heat produced by the contacting portion, due to of electrical conductance, can be transferred to the surface of the connector device across the heat conduction plate or is be transferred by convection when the chip card is plugged into a connector device. Therefore, the temperature of the chip card and the connector device can be dropped, and the disadvantage of shortened lifespan of reader device or chip card because of the produced high temperature of conventional connector device can be avoided.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    Referring to  FIGS. 1 and 2 , an exploded perspective view and an assembled view of an embodiment of the present invention are shown, respectively. A connector device in the present invention includes an insulator body  10 , a plurality of terminals  20 , a cover body  30 , and a heat conduction plate  40 . The terminals  20  are mounted between the insulator body  10  and the cover body  30  on which the heat conduction plate  40  is positioned. In the present invention, by making use of the heat conduction plate  40  to radiate heat, the heat in the connector device can be conducted outside. 
         [0017]    With reference to  FIG. 1 , the lower surface of the insulator body  10 , made of insulated material, is formed with a plurality of terminal-receiving sections  1   1  in parallel, in which the terminals  20  can be accommodated for insertion. On the insulator body  10 , there is an abutting section  12 , in which the terminals  20  can be abutted against. Furthermore, the insulator body  10  is formed with a plurality of engagement slots  13 , which are corresponded to the engagement hooks  32 . On the lower surface of the insulator body  10 , there are a plurality of setting posts  14  for positioning and securing the reader device. 
         [0018]    The terminals  20 , which are electrically connected to a chip card and a reader device, includes an abutting end  21 , a securing portion  22 , a contacting portion  23 , and a coupling end  24 . The terminals  20  are abutted against the abutting section  12  on the insulator body  10  by means of the abutting end  21 . And the terminals  20  are positioned and fixed in between the terminal-receiving sections  11  by means of the securing portion  22 . The coupling end  24  is coupled to other boards disposed on the reader device to form electrical connection. The contacting portion  23 , having the shape of a raised arc, is electrically coupled with a chip card for carrying the data to be transmitted. When a chip card is not plugged into the connector device, the contacting portion  23  can form contact with the guiding groove  41  on the heat conduction plate  40 . When a chip card is plugged into the connector device, it is pushed and pressed due to the resiliency of the contacting portion  23  so that the other face of the chip card is contacted firmly to the guiding groove  41 . So, the improved heat-dissipation effect of the heat conduction plate  40  is achieved. 
         [0019]    The cover body  30 , covered on the insulator body  10 , can enclose the terminals  20 . The cover body  30  has a heat dissipating window  31  whose size and shape are not limited. It should be positioned above the contacting portion  23  of the terminals  20  so that heat can be emitted out when the chip card is plugged in, and the data are being transmitted. In order to discharge heat, natural heat convection can be used when hot air rises. Furthermore, radiation heat or the heat conduction method of the heat conduction plate  40  can be used to dissipate the heat. A plurality of mating plugs  33  raised from and positioned on the surface of the cover body  30  are connected to the heat conduction plate  40  and a plurality of engagement hooks  32  are formed on the lower section at the edge of the cover body  30  to make the cover body  30  to be covered and fixed in the engagement slots  13  of the insulator body  10 . 
         [0020]    The heat-conducing fin  40  positioned above the cover body  30 , is engaged and mated on the mating plugs  33  of the cover body  30  by means of a plurality of mating holes  42  on the heat conduction plate  40 . Because of the locations of the mating plugs  33 , a gap can be formed between the heat conduction plate  40  and the cover body  30  as the convection space of the hot air for the heat in the heat conduction plate  40 , so that the heat produced by the heat conduction plate  40  can be emitted by means of convection for improving upon the efficiency of thermal emission. The heat conduction plate  40  can be made of aluminum, copper, or any other material having high coefficient of thermal conduction for conducting the heat. To emit heat buildup effectively for the chip card produced by the contacting portion  23  of the terminals  20  engaged by the chip card, in the position corresponding to the heat dissipating window  31  on the heat conduction plate  40 , a concave portion of a certain depth is formed towards the heat dissipating window  31  to form a guiding groove  41 , which can properly firmly contact the chip card in the cover body  30 . Apart from the above convection or radiation method for emitting heat, the heat produced by the chip card can be dissipated by conduction method, and to be conducted to the heat conduction plate  40  by means of the guiding groove  41 . Furthermore, the guiding groove  41  can emit all the heat out (in  FIG. 3 ). In addition, for further improving upon the heat dissipating efficiency, a plurality of raised fins can be formed on the surface of the heat conduction plate (not shown in Figure) to increase the heat dissipating surface. But this structure is not a limiting one. 
         [0021]    The structure of the guiding groove  41  can be shown in  FIG. 4 , notwithstanding for  FIG. 1 . In  FIG. 4 , a plurality of small guiding grooves  43  are formed. By means of increasing the surface area of the groove wall of the small guiding grooves  43 , heat dissipating efficiency is improved. The small guiding grooves  43  can be positioned based on design considerations of the connector device or to be corresponding to the position of the contacting portion  23 . Furthermore, another structure of the guiding groove can be shown in  FIG. 5 . In  FIG. 5 , the guiding grooves  44  are spaced and parallel to each other, given the same reason for increasing the surface area of the groove wall of the grooves, and thus the heat dissipating efficiency is improved.
