Description:
FIELD OF THE INVENTION 
   The present invention relates to a computer apparatus assembled wirelessly and particularly to a computer apparatus that establishes electric connection for a plurality of electronic base members such as information storage units, power supply unit, logic processing unit, radiation unit and bus connection unit in an integrated fashion without using wires or cables. 
   BACKGROUND OF THE INVENTION 
   With increasing advances in the information industry, all types of electronic products are designed and made to meet users&#39; requirements. For computers, many different modules also have to be integrated to meet this demand. The general home use desktop computers, notebook computers or standalone servers often encounter a problem of data storage being saturated but having no room for expansion. Hence to integrate the external storage devices has become one of the research and development focuses in the information industry these days. 
   Refer to  FIG. 1  for a present external storage device. The integrated structure must include a plurality of electronic base members such as information storage units, power supply unit, logic processing unit, radiation unit and bus connection unit. Compared with a general single storage device (such as hard disk retrieval rack), the main consideration for integration is to provide an external power supply to drive the external storage device and also provide a radiation unit to maintain a desired internal temperature for the storage device so its operation performance can be maintained at a desired level. However such device cannot get rid of the electric connection adopted on the general computer host. Aside from the information storage units that can employ the retrieval connection type to achieve the convenience of connection without cables, other electronic base members still have to resort power cords or bus flat cables to connect the logic and processing unit and the radiation unit, and the bus connection unit. Such type of assembly takes a lot of working time and operations. In the event of damages happened, the whole set of host casing must be disassembled, and the connection cables have to be removed for repairs and replacement. It also cannot enjoy the benefits of hot-swappable technique and function for the electronic base members. In addition, the connection cables often have extra length, and the host casing must reserve an additional space to accommodate the extra connection cables. As a result, the total size of the device is too big and is not convenient to install or carry. It also does not meet the prevailing trend that demands compact size. Moreover, the extra connection cables hinder the radiation unit to draw and disperse heat from the interior of the device. This directly affects the operation performance of the external storage device. 
   SUMMARY OF THE INVENTION 
   The primary object of the invention is to resolve the aforesaid disadvantages and to overcome the drawbacks of the prior art. The invention mainly employs connectors and connection ports to assemble the electronic base members in the computer apparatus and establish electric connection to replace the conventional connection cables. The size of the whole computer apparatus may be shrunk and repairs and replacement are more convenient. According to the invention, the host casing is divided into a plurality of housing compartments for holding and assembling the electronic base members. Each electronic base member has connectors mating connection ports located on corresponding locations of another electronic base member so that they can be coupled with one another to establish electric connection. Thus when to assemble all the electronic base members in the host casing, there is no need to use extra connection cables to couple with one another to establish electric connection. 
   The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Please referring to  FIGS. 2 and 3 , the computer apparatus assembled wirelessly according to the invention includes a host casing  10  which has the interior dividing into a plurality of housing compartments  11  for housing a plurality of electronic base members. Each electronic base member has a connector  43 ,  511 , or  611  corresponding to and mating a connection port  32 ,  411 ,  412  or  413  located on another electronic base member so that they can be coupled with each other to establish electric connection. Thus when to assemble the electronic base members in the host casing  10 , there is no need to use extra connection cables, and repairs and replacement are more convenient. 
   The electronic base members include information storage units  20 , a power supply unit  30 , a logic processing unit  40 , a radiation unit  50  and a bus connection unit  60 . Each electronic base member has a fastening section  422 ,  521  or  621  for fastening to the host casing  10 . 
   For the information storage units  20 , in the housing compartment  11  of the host casing  10  for housing the information storage units  20 , a plurality of spacers  12  are provided to accommodate a plurality of information storage units  20  at the same time. Each of the information storage units  20  includes a hard disk  21  and a retrieval rack  21  for holding the hard disk  21 . 
   The power supply unit  30  is a circuit board  31  which has electronic elements for transforming voltage and distributing power supply. The circuit board  31  further has a connection port  32  to couple with the logic processing unit  40  to establish electric connection. The circuit board  31  has a rear side which has a power supply insert slot  33  and a switch  34  exposed outside the host casing  10 . 
   The logic processing unit  40  includes a frame  42  and a main board  41  mounting on the frame  42 . The frame  42  has an upper end bent and extended to form a flange  421  and a side end bent to form a fastening section  422  for fastening to the host casing  10 .

   Refer to  FIGS. 4 and 5  for assembling the electronic base members of the invention. As each electronic base member has a gold finger-like connector  43 ,  511  or  611  mating and coupling with a connection port  32 ,  411 , or  412  of another electronic base member to establish electric connection, the order of assembly generally starts from the power supply unit  30  by disposing the circuit board  31  in one housing compartment  11  located at the bottom layer; then the connector  43  of the main board  41  of the logic processing unit  40  is coupled with the connection port  32  of the circuit board  31  of the power supply unit  30 , and the fastening section  422  of the main board  41  is fastened to the host casing  10  through fasteners  423 ; next, the connectors  511  and  611  on the circuit boards  51  and  61  of the radiation unit  50  and the bus connection unit  60  are coupled with the connection ports  411  and  412  of the main board  41  to establish electric connection, and the fastening sections  521  and  621  located thereon are fastened respectively to the host casing  10  through fasteners  523  and  622 . Finally, the information storage units  20  are placed between the spacers  12  to complete assembly of the computer apparatus. 
   As the aforesaid electronic base members do not need connection cables to establish electric connection during assembly, assembly or repairs and replacement in the future can be done with reduced time and process. There is also no need to allocate space to accommodate extra connection cables. Thus the size of the computer apparatus may be effectively shrunk. Furthermore, without the hindrance of extra connection cables, thermal energy generated by the electronic base members can be discharged easily through the radiation unit  50  to maintain normal operation.
