Field of the Invention The present invention relates to a duplex device for a circuit device, and particularly to a multiplexer circuit device for a coaxial multimedia alliance (M〇CA). [Prior Art] Ethernet Cable has been the main wiring solution for digital homes for many years. 'It can be used between rooms in the home. • Transmit audio, video and digital data' even connecting the entire residential audio system. φ to everything from home automation and safety systems. However, Ethernet is not the ideal choice 'because installing an Ethernet cable in a built home' requires wall-to-wall to break the hardware structure, which is sometimes more difficult than building a new house. higher cost. In addition, the installation of the Ethernet network is indispensable for the professional installer. Therefore, there are new ways for the industry to support and create digital home infrastructure. They mainly use the circuit line that exists in almost every family, that is, the wires and coaxial of both new buildings and old buildings. Cable. Depending on the circuit trunk used, this new digital home networking technology is named HomePlug AV and MoCA (short for Multimedia over Coax Alliance). The organization that develops and promotes these two technologies is the Home Power Line Networking Alliance (HomePlug). Powerline Alliance) and the Multimedia over Coax Alliance. To put it simply, HomePlug AV uses ordinary power, such as the power line of the power company, which may be the most popular line in the average family. 5200830752 cable, as long as the power line can be used to provide digital bandwidth in the general household. No additional Ethernet cable is required. The technology of MoCA is basically the same as the establishment of a network of four (four) (four), but the wire is the use of coaxial power, which is mainly used to send multiple high-quality videos from one room to another. To install a MoCA network in the home, simply connect the MoCA multiplexer (also known as an adapter) to the coaxial cable to provide telephone service and computer data networking on a coaxial cable. Also provides enough bandwidth to meet the need for remote control of the video's data stream

[Embodiment] The foregoing and other technical contents, features and effects of the present invention are incorporated in the following references. A detailed description of a preferred embodiment of the drawings will be apparent. As shown in Figures 2 and 3, the present invention is directed to a preferred embodiment of a multiplexer-circuit device 2 for a coaxial multimedia alliance, and includes There is a housing 20, a circuit board 22, a first adapter unit 24, a second adapter unit 26, a spacer 28, a surge protector 29, an input terminal 3, and an output terminal 4. The housing 20 can define an accommodating space 200. The circuit board 22 is disposed in the accommodating space 200. The first aligning unit 24 is disposed on the circuit board 22 and respectively connected to the input terminal 3 The output end 4 is electrically connected, and the first adapting unit 2 4 having a first high pass filter group HPF1, and a first low pass filter group LPF1 in series with the first high pass filter group HPF1. The first high pass filter group • HPF1 and the first low pass filter group LPF1 are majority The coil 240 is configured to allow the first adapting unit 24 to pass signals having a frequency of 5 MHz to 860 MHz. The second adapting unit 26 is disposed on the circuit board 22 and connected in parallel with the first adapting unit 24. That is, it is also electrically connected to the input terminal 3 and the output terminal 4. The second adapter unit 26 has a second high-pass filter group HPF2, and a second low-pass filter group LPF2 connected in series with the second high-pass filter group HPF2. The second high-pass filter group HPF2 and the second low-pass filter group LPF2 are 8 200830752. The plurality of coils 260 are formed, and the second adapting unit 26 is allowed to pass signals with a frequency of 975 MHz to 1525 MHz. The spacer 28 is disposed between the first low pass filter group LPF1 of the first adapter unit 24 and the second low pass filter group LPF2 of the second adapter unit 26. The height of the spacer 28 is higher than the height of all of the coils 240, 260 of the first and second adapter units 24, 26. In the present embodiment, the spacer 28 is a thin metal plate. The surge protector 29 is disposed on the circuit board 22 between the input terminal 4 and the first and second adapter units 24, 26. In operation, the signal enters the multiplexer circuit device 2 from the input terminal 3 and simultaneously enters the first adapter unit 24 and the second adapter unit 26, since the first adapter unit 24 constitutes a The low-pass filter band of 5 MHz to 860 MHz, and the second adaptation unit 26 constitutes a band-pass filter band of 975 MHz to 1525 MHz, so that most of the signals of the lower band can be derived from the first adaptation unit 24, and Most of the signals of the high frequency band can be derived from the second adaptation unit 26. The spacer 28 disposed between the first low-pass filter group LPF1 of the first adaptation unit 24 and the second low-pass filter group LPF2 of the second adaptation unit 26 has a height higher than the first The heights of all the coils 240, 260 of the first and second adapter units 24, 26 are such that the electromagnetic energy that is relatively easy to occur in the signal of the higher frequency band (975 MHz to 1525 MHz) of the second adaptation unit 26 is The shielding energy of the spacer 28 is blocked, and the electromagnetic energy in the first matching unit 24 coupled to the lower frequency band (5 MHz to 860 MHz) is reduced, thereby making the first and second suitable for the two different frequency bands. With the single 9 200830752 - the amount of interference between the signals in the 24, 26, 26, 26, effectively improve the quality of the signal transmission, provide operational stability of the electrical equipment used in conjunction with; at the same time set in the input 3 and the first and second The surge protector 29 of the unit 24, 26 is adapted to effectively protect the entire multiplexer circuit device 2 from the surge caused by external factors such as lightning strikes or sudden power failures. Burned down. Referring to FIG. 4, it is a schematic diagram of a frequency-to-noise ratio waveform obtained by the conventional multiplexer 1 (see FIG. 1) circuit device and the multiplexer circuit device 2 provided with the spacer 28. It can be clearly seen from the figure that the attenuation range of the noise range of the present embodiment is much higher than the conventional one in the frequency range of 15 MHz to 855 MHz, so that the multiplexer circuit of the present invention for the coaxial multimedia alliance can be determined. The device 2 can effectively reduce the electromagnetic energy generated by the electromagnetic energy generated by the higher frequency band (975MHz~1525MHz) circuit to the lower frequency band (5MHz~860MHz) circuit, so that the shielding effect of the shielding electromagnetic energy of the embodiment is obvious. It is better than the conventional one. In summary, the multiplexer circuit and device 2 of the present invention for the coaxial multimedia alliance is configured by the spacer 28 to effectively shield and reduce the mutual generation of the first and second adapter units 24, 26. The amount of electromagnetic energy interfered with, thereby improving the quality of the signal transmission and providing operational stability of the equipment used in combination, so that the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent. 10 200830752
