Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ** group that is provided in a remote monitoring and control device and that sends and receives input data from external devices and devices.

Conventionally, signal line connections between off-frame equipment and on-board input circuits have been made through printed circuit boards on which connectors and wrapping posts are mounted, and interface voltages have been applied to the input circuit section.

FIG. 1 shows #/! of this conventional connection group Ii. It is an explanatory diagram showing one cost. In II, the conventional connection base #i is attached to the end of the cable from outside the rack and connects to the connector 11 signal ##l! that is fitted into the connector. This is a printed circuit board consisting of a wrapping post 2 and a wrapping post 3 for adding luxury. :7 Connector 1 and the wrapping post 2, and between the wrapping post 3 and the board connector part 40 are printed wiring, and the board connector part 4 is connected to the input circuit part by cable.

In this connection board, an interface voltage is applied to the input circuit section, and a current flows to the outside *S through the board connector section 4, wrapping post 3, wrapping post 2, and connector l, thereby exchanging data.

However, with this conventional connection board, the interface power supply had to be applied to the input circuit section, and the interface power supply had to be wired to the input circuit section inside the rack.

The present invention has been developed in view of these drawbacks, and includes:
An interface power supply terminal is provided on the connector board that connects the signal line from outside the rack, and the interface voltage is applied to the input circuit from here to avoid running unnecessary wiring inside the rack. wrapping post)
It is an object of the present invention to provide a connection board for a method monitoring and control device that allows easy and quick changes in power supply wiring.

That is, the present invention provides a connection board that is inserted between a signal line from outside the rack and an input circuit inside the rack, and transmits and receives input data from the outside device to a remote monitoring and control device. It consists of an interface electrical terminal mounted on a board along with a connector and a wrapping post.

Hereinafter, the present invention will be explained based on 1IIIiK embodiments.

Figure 2 shows an example of this invention. ji diagram.

111KTh item, zero source - ** The board has a connector l, wrapping posts 2 and 3, and an interface power terminal 5.
is mounted on a printed circuit board.

The connector 1 is mated with the external line connector, and the interface power terminal 5, which is a screw terminal, is connected to the interface power line. The board connector s4 is connected to an input circuit of a remote monitoring and control device (not shown).

The connector L and the A part of the wrapping post 2, the board connector Iku 4, and the A11l of the wrapping post 3 are printed wiring, respectively.
The 0B section is also printed and wired on the board.

In such a configuration, in the wrapping post 2 (including the wrapping boss) 3, the wrapping posts of parts A and 8 are wrapped to the appropriate position 114), the interface voltage is applied to the input circuit, and the external Exchange data. Father, you can also change the power supply IIO using the wrapping post on the same aircraft.

As explained above, one invention was made to connect the signal line from outside the rack*
* By providing an interface power supply terminal on the connector board, the interface voltage is applied to the input circuit from here, and excess wiring is routed inside the rack, and the wrapping post on the connector board is (b) Changes in the electric wire arrangement can be made easily and quickly.
