The content of the invention
The invention technical problem to be solved
However, when using RJ45 connectors as the connector that RS-485 communicates, probably can occur to be led by misconnection
The problem of " forfeiture of communication function " and " failure of RS-485 circuits " that causes.That is, ethernet communication terminal and
In the terminal of RS-485 communications, the mode of pin configuration is different.In addition.As shown in figure 3, in ethernet device 1, connector 11
Signal pins to be the 1st pin and the 2nd pin be connected via pulse transformer 13, D.C. resistance is changed into 0 Ω.Therefore, mistake is worked as
Ethernet device 1 is connected in one end of communication cable by mistake, when the other end connects RS-485 equipment 2, it may occur that transmitting-receiving
The side of the positive electrode and negative side of signal are short-circuit via transformer, it is impossible to the problem of communicating such.In this case, there is also because
The problem of design causes dump.In addition, as shown in figure 4, RS-485 communication in, due to multiple RS-485 equipment 2 simultaneously
Connection, therefore when the dump of 1 RS-485 equipment 2, all had an impact by RS-485 equipment 2 in parallel.In addition, also wanting to
The temperature for having arrived equipment 1,2 rises and equivalent risk of smoldering.
The present invention makes to solve the above problems, its object is to there is provided one kind with transformer, and energy
In the node apparatus of the communication cable of enough commonly connected different communication specifications, caused by can avoiding the misconnection of communication cable
The node apparatus of influence.
The technological means solved the problems, such as
Node apparatus of the present invention has：Can commonly connected different communication specification communication cable connector；One
End is connected to the signal wire of connector；It is connected to the other end of signal wire and transmits the transformer of signal；And in series
It is inserted into the capacitor of signal wire.
The effect of invention
According to the present invention, by above-mentioned structure, with transformer, and it is capable of the logical of commonly connected different communication specification
In the node apparatus of communication cable, the influence caused by the misconnection of communication cable can be avoided.

Embodiment
Hereinafter, the embodiment referring to the drawings to the invention is described in detail.
Embodiment 1
Fig. 1 is the figure for the configuration example for showing the node apparatus that embodiments of the present invention 1 are related to.In addition, in fig. 1 it is shown that
Ethernet device 1 has been used as the situation of node apparatus.
As shown in figure 1, in ethernet device 1, possessing connector 11, signal wire 12, pulse transformer (transformer) 13, common mode
Choking-winding 14 and chip capacitor (capacitor) 15.
Connector 11 can commonly connected different communication specification communication cable.Ethernet communication and RS- can for example be enumerated
485 communications are used as different telecommunications metrics.By the connector 11, other node apparatus can be connected via communication cable,
So as to carry out the exchange of various information between device.In addition, in the ethernet device 1 shown in Fig. 1, being connected using RJ45
Device is signal pins as the pin of connector the 11, the 1st and the 2nd pin.
Signal wire 12 connects connector 11 and pulse transformer 13 via common mode choke coil 14 and chip capacitor 15
Connect.
Pulse transformer 13 transmits the signal of receiving and transmitting signal.In the pulse transformer 13, process circuit (not shown)
Primary side is connected, signal wire 12 is connected secondary side.In addition, pulse transformer 13 is also quiet to avoid with being insulated
Electricity enters the function of process circuit side.
Common mode choke coil 14 is arranged on the signal wire 12 between connector 11 and pulse transformer 13.The common mode chokes
Coil 14 has the function of removing the common-mode noise transmitted in signal wire 12.
Chip capacitor 15 is inserted into signal wire 12 in series.The chip capacitor 15, which has, to be breaking in signal wire 12
The function of the DC component of flowing.In the RJ45 connectors shown in Fig. 1, because signal wire 12 is connected to the 1st pin and the 2nd
Pin, therefore relative to 2 signal wires 12 of each chip capacitor 15 are inserted into.In addition, the capacity of chip capacitor 15 according to
Frequency of the signal used in node apparatus etc. is suitably set.
In addition in fig. 1 it is shown that by chip capacitor 15 located at situation between connector 11 and common mode choke coil 14,
But chip capacitor 15 can also be located between common mode choke coil 14 and pulse transformer 13.
Next, the effect of the node apparatus to constituting as described above is illustrated.
In the present invention, two signals each chip capacitor 15 inserted between connector 11 and pulse voltage device 13 in series
Line 12.Thus, even if as shown in Fig. 2 power supply is supplied to the 1st pin and the 2nd pin due to the misconnection of communication cable, directly
Flow component (DC signals) is also cut off by chip capacitor 15, can avoid its influence.On the other hand, normally connect in communication cable
In the case of connecing, because the signal of communication as AC signals is not influenceed by chip capacitor 15, therefore can normally it transmit
Signal.
In summary, according to the embodiment 1, due to possess can commonly connected different communication specification communication cable company
Connect the signal wire 12 that device 11, one end are connected to connector 11, the arteries and veins for being connected to the other end of signal wire 12 and transmitting signal
Rush transformer 13 and be inserted into the chip capacitor 15 of signal wire 12 in series, therefore with transformer, and can be public
Altogether in the node apparatus of the communication cable of connection different communication specification, caused by can inexpensively avoiding the misconnection of communication cable
Influence.Even if that is, communication cable misconnection, is also possible to prevent fault, so that even in there is multiple nodes to fill
Put the influence that in the case of being connected generation system can also be avoided integrally to communicate.Further, since the capacity can also be compared with
It is small, therefore low cost can be realized and spatialization is saved.
In addition, in above-mentioned, it is assumed that ethernet communication and the situation of RS-485 communications are said as multiple telecommunications metrics
Understand the situation that the chip capacitor 15 of the present invention is set in ethernet device 1.However it is not limited to this, as long as with change
Depressor, is capable of the node apparatus of the communication cable of commonly connected different communication specification, all can be similarly using the present invention.In addition,
Enumerate such as communicating LONWORKS (registration mark) as other telecommunications metrics.
In addition, in above-mentioned, show relative to the 1st pin of RJ45 connectors and the pin of the 2nd pin to by chip
The situation that capacitor 15 is inserted in series.On the other hand, pin configuration during RJ45 connectors is used in RS-485 equipment 2
Not by special provision.Therefore, the 3rd pin and the pin of the 6th pin relative to RJ45 connectors are had according to pin configuration
Situation to needing chip capacitor 15.
In addition, in the case where ethernet communication mode is 1000Base-T, the 4th pin of RJ45 connectors and the 5th pin
The pin of pin pair and the 7th pin and the 8th pin is to also turning into the insertion object of chip capacitor 15.
In addition in above-mentioned, show a case that to set common mode choke coil 14, this is not essential structure, can also save
Slightly.
In addition in above-mentioned, provided with 2 chip capacitors 15, but can be with only one of which from the viewpoint of DC component is removed.
In addition, the present application in the range of the invention, can carry out the change of the arbitrary inscape of embodiment
Shape, or the arbitrary inscape of embodiment omission.Symbol description
