         [0005]    In order to enable people to effectively utilized these electric devices and transmit the information in their living quarters and working environment as required, conventionally, connection port devices are designed to be embedded in wall or under floor in the living quarters or working environments. Usually, this kind of connection port device not only includes the traditional power supply socket, it but also includes telephone line connection port or network port. Though this kind of design may achieve the purposes of both esthetics and practicality, however, the related electronic device is required to use more than two connection port devices at the same time to provide normal and complete functions. By way of example, some of the in-house telephone device must be provided with power supply sockets and telephone line connection port to be able to function normally; while the personal computer are required to have power supply socket and network connection port, thus being able to get on the network to proceed with various operations required. 
         [0006]    In addition to the afore-mentioned connection port devices, in recent years, various plug-and-play embedded memory (for example, various memory cards), or various data transmission interfaces (for example, Universal Serial Bus (USB)) are developed for the information processing device. Wherein, for the Universal Serial Bus (USB), it is designed to have the advantages of plug-and-play, hot swapping functions and high transmission speed. In addition, it is provided with the rechargeable functions of the portable information product (such as MP3, digital camera, etc.). However, this kind of design involves some over-complicated interface Specifications, and may result in quite a lot of trouble and inconvenience for the user in operating such an electronic information device. Therefore, the problem of how to integrate and utilize the connection ports of various specifications and be compatible with the requirement of future trend, is probably the most urgent task that has to be solved in this field.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    The purpose, construction, features, and functions of the invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings. 
         [0015]    Firstly, refer to  FIG. 1  for a schematic diagram of a composite connection port device according to a first embodiment of the invention. As shown in  FIG. 1 , the composite connection port device of the invention includes a plurality of output connection ports and a built-in wireless transmission module. The output connection can be classified into a power connection port (for example, power supply socket  115  and USB port  111 ) and a signal connection port (for example, memory card port  112 , network port  113 , telephone port  114 , optical fiber port  116 , and high speed digital port  117 ), and each of which will be described as follows. Wherein, USB port  111  can be provided in plurality, having the capability of forming into a USB hub, and is capable of providing working power and transmitting data required at the same time. By way of example, a user may charge a portable digital player (MP3)  30  directly through a USB port  111 , or read the photograph data stored in a digital camera  20  through a USB port  111  connected thereto. The USB port  111  can be replaced by other ports (such as IEEE 1394) having power supply and data transmission capabilities. The memory card port  112  is used to provide data transmission to memory card  50 . Likewise, the network port  113  (schematically shown as connected to a notebook computer  80 ), the telephone port  114  (schematically shown as connected to a telephone device  40 ) can be connected to the corresponding devices for data transmission. The high speed digital port  117  is a High Definition Multimedia Interface (HDMI) compatible with various digital requirements of the future trend. The wireless transmission module can be used to communicate and transmit information directly to an external wireless transmission system  90 . The power supply socket  115  is utilized to provide the local power supply directly to a data processing device  70  or various electronic devices  60  (for example, television, audio device, etc.). Taking into consideration of future requirements, in the invention, an optical fiber port  116  is also provided for connecting to the related device and transmitting optical signals. 
         [0016]    Subsequently, the internal system framework of the invention is described in detail. Refer to  FIG. 2  for a schematic diagram of the system framework of a composite connection port device according to a first embodiment of the invention. In the structure, the input terminals include a local power supply terminal AC, a signal terminal Signal, and an optical fiber network terminal OP. Wherein, upon receiving the local power supply, it is separated and transmitted into two braches. In one branch, the power is transmitted directly to a power supply socket  155  to provide power to ordinary electronic devices (for example, television, audio device, etc.). In the other branch, power is transmitted to a power processing unit  11 , where it is rectified and voltage reduced to form a power supply of working voltage and is transmitted to a USB port (USB hub)  111 . The power processing unit  11  includes a buck circuit and a rectifier circuit, while voltage stabilization and current restriction functions are also provided. The signal processing unit  12  is coupled to a USB port  111 , a memory card port  112 , a network port  113 , a telephone port  114 , and a high speed digital port  117 , with its major function as providing connections between/among various ports; meanwhile, it may communicate with a signal terminal Signal, hereby transmitting signals and data thereto. At the same time, the signal processing unit  12  is connected to a wireless transmission module  13 , thus being able to transmit/receive data and messages to/from an external wireless transmission system. The optical fiber port  116  corresponds directly to an optical fiber network terminal OP, and is used to transmit and receive the optical signals. 
         [0017]    In addition, refer to  FIG. 3  for a schematic diagram of a composite connection port device according to a second embodiment of the invention. And this is a variant of the first embodiment of the same invention described above. 
         [0018]    Nowadays, in the living quarters of most of the people, the density of power lines distribution is quite enormous. In case that the data signals can be coupled into these power lines, then the cost and effort of signal line layout and installation can be saved, meanwhile, the interference between microwaves utilized in wireless transmission can also be eliminated. The prerequisite of realizing the second embodiment is that, both the power signals and data signals can be transmitted through the same input terminal, thus achieving the functions and effectiveness of the invention. Therefore, as shown in  FIG. 3  that power lines are connected to the local power supply terminal AC, hereby forming  3  composite connection port devices  10 ( a - c ). In this configuration, a composite connection port device  10   a  is connected to an information processing device  70   a  and a notebook computer  80 , and due to the characteristic of the invention that it is capable of providing the power supply and performing data transmission required at the same time, thus the information processing device  70   a  and the notebook computer  80  may not only have the power to function, but also may perform data transmission to each other; moreover, a composite connection port device  10   b  is connected to an information processing device  70   b,  thus information processing device  70   b  may likewise transmit data signals to an information processing device  70   a  and the notebook computer  80 ; furthermore, in a similar manner, the data stored in a memory card  50  connected to a composite connection port device  10   c  can be read simultaneously by information processing devices  70 ( a - b ) and notebook computer  80 . Meanwhile, a built-in wireless transmission module is provided in composite connection port device  10   c,  thus it may communicate with a wireless transmission system  90  at the same time. Therefore, all the devices are connected together in this manner to communicate information with each other, hereby achieving the convenience in operation without having to add and install additional network lines. 
         [0019]    Finally, refer to  FIG. 4  for a schematic diagram of the system framework of a composite connection port device according to a second embodiment of the invention. In this embodiment, it is assumed that data transmissions are achieved through utilizing power lines, as such, the input terminals may only include a local power supply terminal AC and a signal terminal Signal connected to power line and an optical fiber network terminal OP. In this situation, the input local power supply will first be transmitted to a power processing unit  11 , where it is branched into two separate routes for transmission. Wherein, one route is used to transmit the power supply to a power supply socket  115 , hereby providing power supply to ordinary electronic devices (for example, TV and audio devices) for utilization. In the other route, power supply is transmitted through power processing unit  11 , where it is rectified and voltage-reduced to form a working voltage power supply, and is transmitted to USB port (USB hub)  111 . The power processing unit  11  includes a buck circuit and a rectifier circuit, while the voltage stabilization and current restriction functions are also provided. Through a signal terminal Signal, data signals are transmitted via a signal separation circuit in a power processing unit  11  to a signal processing unit  12 , and then it is coupled to a USB port  111 , a memory card port  112 , a network port  113 , a telephone port  114 , and a high speed digital port  117 . Wherein, signal processing unit  12  is in charge of coupling between/among various ports for data signals, meanwhile, it is connected to a signal terminal Signal through power processing unit  11  for transmitting data signals. At the same time, the signal processing unit  12  is coupled to a wireless transmission module  13 , thus it may transmit and receive data signals to and from an external wireless transmission system. The optical fiber port  116  corresponds directly to an optical fiber network terminal OP, and is used to transmit and receive optical signals. 
         [0020]    The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
