ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a rectifying device, and more particularly to a rectifying device outputting multiple power signals.
BACKGROUND OF THE INVENTION
Owing to the electrification and the popularization of computer, there are usually a lot of electronic devices used in a house now. A problem of the power supply is then encountered. The consumed power of several electronic devices, such as speakers and modem, is not so much but each of these devices needs a specific voltage. Therefore, a rectifying device is necessary for this kind of electronic device. The volume of a conventional rectifying device is relatively big. However, the number of sockets in a house is commonly limited. Usually, two or three sockets are arranged together. That is, a rectifying device only provides one voltage but occupies two to three sockets in a time. When an electronic device is used, some sockets may be covered by the rectifying device and can not be used. When several electronic devices are used at the same time, the number of the sockets may not be enough. So, it is tried by the applicant to deal with the problem encountered in the prior art.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide a rectifying device outputting a plurality of power signals.
According to the present invention, the rectifying device includes a rectifying device body receiving and rectifying a first power signal from a power source for generating a third power signal and an outlet mounted on the rectifying device body and electrically connected with the power source for supplying a second power signal. The rectifying device further includes an inlet having a plurality of conducting pieces electrically connected with the power source. These conducting pieces are made of copper. The first power signal is connected with the second power signal in parallel.
Certainly, the rectifying device body includes a first housing, a second housing, and a circuit board positioned between the first housing and the second housing. The rectifying device body further includes a connector mounted on the circuit board and electrically connected between the outlet and the inlet for transmitting the first power signal therethrough. The circuit board has a power converter for generating and supplying the third power signal.
Certainly, the first housing of the rectifying device has an opening for mounting the outlet thereon. The second housing has a plurality of holes for enabling the conducting pieces to protrude from the second housing. Besides, the second housing has a plurality of holders disposed at the inner periphery thereof for holding the circuit board.
Certainly, the circuit board includes a plurality of grooves for engaging with the connector and a plurality of holes for enabling the conducting pieces to protrude from the circuit board and electrically connected with the connector. In addition, the power converter of the circuit board has a rectifying circuit and a voltage-stabilizing circuit for rectifying the first power signal steadily.
Certainly, the connector of the rectifying device includes a plurality of tongues correspondingly aligned with a plurality of grooves formed on the circuit board for securing the connector to the circuit board. The connector further includes a first connecting element electrically connected to the outlet and a second connecting element electrically connected to the inlet.
Certainly, the outlet of the rectifying device includes an output end supplying the second power signal, an input end electrically connected to the connector, and a fixing unit having a plurality of elastic pieces for securing the outlet to the first housing. The elastic pieces bias against and thus attach to the first housing when the outlet is inserted into an opening of the first housing. The output end of the outlet includes a plurality of plug holes. The input end of the outlet includes a plurality of plug pins.
Certainly, the parameters of the second power signal are the same as those of the first power signal. The parameters of the third power signal are different from those of the first power signal. The first power signal is an alternative current (AC) signal.
The present invention may best be understood through the following description with reference to the accompanying drawings, in which:
