Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present utility model, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present utility model, and the embodiments can be mutually combined and referred to without contradiction.

The first embodiment of the utility model relates to a multipurpose POE power supply conversion joint circuit, which comprises an input interface with eight pins, wherein the 1 st, 2 nd, 3 rd and 6 th pins and the 4 th, 5 th, 7 th and 8 th pins of the input interface are respectively a group of external pins, and each group of external pins is connected to the 1 st, 2 nd, 3 rd and 6 th pins of an output joint of the eight pins through a network transformer.

Therefore, when the input interface outputs the power supply data mixed signal, the data signal of the 1236 pin is filtered into continuous current based on the action of the network transformer, so that the effect of two paths of stable power supply is realized, the network transformer has the effects of signal coupling, high-voltage isolation, impedance matching, electromagnetic interference suppression and the like, and two paths of stable output data signals can be further output to the output interface, so that the output of the one-to-two power supply and the data mixed signal is realized.

The second embodiment of the present utility model is substantially the same as the first embodiment, and mainly consists in that the common mode inductance of the network transformer is at the PHY side.

Therefore, compared with a network transformer with common-mode inductance at a cable end, the circuit of the data output signal is subjected to common-mode inductance filtering and isolation, and the signal is stable and reliable.

Further, the input interface and the output connector are RJ45 connectors.

The third embodiment of the present utility model is substantially the same as the first embodiment, and mainly consists in the preferred scheme of the network transformer receiving the data signal, in which the digital output terminals are connected to pins 4, 5, 7, 8 of the output connector.

Further, the digital output end of the network transformer is connected to the circuit of the output connector in series with a dial switch.

Generally, for devices connected to the output interface, the power modes may be different, some are power and data signals on pins 1236, some are power signals on pins 1236 and data signals on pins 4578, so setting the dial switch to adjust the mode of the output interface to match the corresponding device connected to the output interface.

Further, the digital output end of the dial switch is connected to the circuits of the 4 th, 5 th, 7 th and 8 th pins of the output connector in a way of connecting two pins in parallel. Thus realizing the output of the power supply and the data mixed signal in a one-to-two mode in the simplest circuit mode.

Furthermore, the dial switch is connected in a double-pole double-throw mode corresponding to a group of external pins.

As a most preferable scheme of the dial switch, the dial switch is an SS22E01 direct-plug double-row 6-pin 2P2T dial switch.

In combination with the above embodiment, as shown in fig. 1, the fourth embodiment of the present utility model is generally two pairs of power converters used together, and any one of the two power converters can be used as a power supply converter or a power receiving converter, and can realize two network port power sources and data transmission:

the output interface P3 or the output interface P2 is an independent port of the power supply end or the power receiving end, and the dial switch S1 or the dial switch S2 is responsible for controlling the power input/output mode selection of the power supply end or the power receiving end and is responsible for switching to 1236 pin or 4578 pin lines for power supply and power receiving.

The network transformer T1 and the network transformer T2 are responsible for separating and mixing the power and data signals.

Input interface J105 is a power data mix and may have two sets, one set for 1236 pins and one set for 4578 pins.

1. When the output interface P3 is used as a power supply end, if the POE network adopts the 1236 pin to supply power, the network transformer T1 can separate power and data signals, and if the dial switch S1 is dialed to the upper part to enable the two ends of the adjustable end of the transformer in the network transformer T1 to be communicated, the separated power is mixed to the 1236 pin of the input interface J105 through the network transformer T1; if the POE network supplies power to the 4578 pin, when the dial switch S1 needs to dial to the lower side of the diagram to connect the network transformer T1 and the 4578 pin of the output interface P3, the power supply mixes the data signal to the 1236 pin of the input interface J105 via the network transformer T1.

Output interface P2 and output interface P3 are the same, mixing power and data signals to pins 4578 of input interface J105.

2. When the power receiving device is used as a power receiving end, when the dial switch S1 is dialed to the upper part to enable two ends of an adjustable end of a transformer in the network transformer T1 to be communicated, 1236 power supply and data mixed signals on the input interface J105 are separated through the network transformer T1, and are mixed to a 1236 pin of P3 through the dial switch S1 and then through the network transformer T1, and at the moment, the power receiving device supplies power to the 1236 pin; when the dial switch S1 is dialed to the lower side to enable the network transformer T1 to be communicated with the 4578 pin of the output interface P3, the power separated by the network transformer T1 is directly output to the 4578 pin of the output interface P3 through the dial switch S1, and at the moment, the power receiving end supplies power to the 4578 pin, and the 1236 pin of the output interface P3 is only a data signal.

Similarly, pin 4578 of the input interface J105 is a power and data mixed signal, when the dial switch S2 is pulled up, the output interface P2 is 1236 pin to supply power to the powered device, and when the dial switch S2 is pulled down, pin 4578 is pin to supply power to the powered device.

It will be readily appreciated that this embodiment is the most preferred embodiment of the utility model when embodied.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the utility model and that various changes in form and details may be made therein without departing from the spirit and scope of the utility model.
