Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a line terminal switch, and more particularly to a switch for interconnecting line terminals connected to lines of different standards.

[0002]

2. Description of the Related Art For example, if one line is based on the RS232C standard and the other line is based on the current standard, when the A and B devices using the lines of these different standards are to be interconnected, the RS232C standard In contrast to the 25-pin line connector connected to the line, the current standard line uses only 2 pins on the sending side and 2 pins on the lead side. In addition, the terminal arrangement may be checked for each device using a monitor device. There is one procedure when exchanging data between the device A and the device B using a line, and there is a signal to open whether or not the other side is connected by hardware or whether it is matching. RS2
It may be that the first pin is not so in the current standard, although it is assigned to, for example, the first pin of 25 pins of 32C. In this way, the function of each pin may differ in the connector interfaces of the device A and the device B.

[0003]

In the line on the device A side and the line on the device B side, when the functions of, for example, the first pin on the device A side and the first pin on the device B side are different from each other, conventionally, lines corresponding to each other are used. Are connected and soldered,
It is a time consuming and labor intensive task. Furthermore, when the A device and the B device are exchanging data between RS232C lines or between current lines, the exchange of data is monitored, and therefore R
A monitor device according to the S232C standard has been developed. When data is exchanged between the A device and the B device by the RS232C method, there is no problem in monitoring the signal line with this monitor device, but the A device and the B device use the current line to transmit the data. If it is attempted to monitor the exchange of this data during the exchange of data, the conventional monitor device cannot be used as it is.
It must be monitored after converting to the S232C system. Therefore, an object of the present invention is that two lines connecting two devices A and B comply with different standards, or a device that monitors data exchange between lines of the same standard does not conform to the standard. At some time, it is an object of the present invention to provide a line terminal switching device that can easily and accurately switch the terminals in the interface of the connector and that enables the diversification of the switching of the line terminals.

[0004]

The line terminal switch of the present invention has line terminals (1 ', 2' ...
24 ', 25') and a circuit terminal (1 ", of a line according to the above standard or a standard different from the first connector)
2 ″, ... 24 ″, 25 ″), and a second connector having line terminals (1 ′, 2 ′ ... 2)
4 ', 25') are rotary switches (1, 2, ... 24, 2)
5), each connected to a rotary switch (1, 2,
.., 24, 25), and the signal flows only to any one of the line terminals (1 ", 2", ... 24 ", 25") of the second connector. It is characterized in that the line terminal of the first connector is switched and connected to a predetermined line terminal of the second connector by switching the rotary switches (1, 2, ..., 24, 25).

[0005]

That is, according to the present invention, the first and second connectors are arranged in the line terminal switcher, respectively, and the first connector is provided with the line terminal of the line according to a certain standard, and the second connector is provided with the above standard. When the line terminals of the lines conforming to the same or different standards are provided, the line terminals of the first connector are respectively connected to the rotary switches, and the switching connection portion of each rotary switch has the circuit terminal having the first connector. A signal is connected to the corresponding line terminal of the second connector so that the signal is transmitted only in the forward direction, and the line terminal of the first connector is changed to the corresponding line of the second connector by switching the switching connection portion of the rotary switch. Connect to each terminal.
