[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector that relays a plurality of circuits that connect, for example, a computer and a plurality of sensors.

[0002]

[Prior art]

 Conventionally, automatic machines, robots, etc. are provided with a large number of sensors for confirming the presence or absence of a work and detecting the position of each part of the equipment. As a connector for connecting these sensors to a control device such as a computer, for example, as shown in FIG. 5, a pair of connectors including a control terminal connector 101 and a terminal terminal connector 102 that are grouped together. There is a structured one.

This conventional example has the following drawbacks, for example. That is, when the circuit is changed or the control device is replaced, the necessary lines must be separated from the integrated connectors 101 and 102. It may not be possible to remove the other pole of a connector to which security equipment is connected. When handling limit switches, sensors, etc. as an assembly, there is a drawback that the connector cannot be manufactured and stored as a completed product, and many precautions must be taken during storage.

Further, in general, a method of storing the signal line extending from the sensor 104 as one assembly connected to the contact 103 is often adopted. In the case of storage as an assembly, the contact 103, which is an important part, is exposed, and there are many precautions for storage. In order to eliminate such a drawback of the conventional connector, a connector as shown in, for example, FIG. 6 has been proposed (Japanese Patent Application No. 2-271147), though it is not known.

In the connector according to this prior application, the cable wire 201 collectively led out from the control device is introduced into the cover 202, and the control side connecting electric wire 203 gathered in the cover 202 is divided for each signal. It is connected to the control side connection contact 204. The control connection side contact 204 is fitted in and supported by the control side connector 205. On the device side to which the sensor 206 is connected, the device-side connecting electric wire 207 led out from the sensor 206 is connected to the device-side contact 208. The device-side contact 208 is detachably fitted and supported by the device-side connector 209.

In the connector according to this prior application, by connecting the control-side connector 205 and the device-side connector 209, various signal lines gathered by the control-side connector 205 are formed so as to be distributed independently for each circuit. Will be. An address is given to each of the circuits that are distributed and made independent, and the address is displayed on the mark sheet 210 attached to the control-side connector 205.

[0007]

[Problems to be solved by the device]

 However, in the connector according to this prior application, when the control connection side contact 204 is fitted into the control side connector 205, the control connection side contact 204 and the control side connector 205 are checked while checking the number of each control side connection electric wire 203 and the drawing. It is necessary to assign an address, and a lot of time and effort are spent in the work of assigning the address. Also, if this addressing is wrong, the error cannot be found at the wiring check stage, and malfunction occurs at the trial run stage, and the cause cannot be easily found. Will occur.

The present invention has been made in view of the above circumstances, and is a connector in which a plurality of circuits provided across a control device and a plurality of terminal devices are relayed, and a terminal side relay structure is distributed and independent for each circuit. In the above, the purpose is to prevent addressing errors.

[0009]

 In the present invention, in order to achieve the above object, in a connector in which a plurality of circuits provided over a control device and a plurality of terminal devices are relayed and a terminal side relay structure is distributed and independent for each circuit, A connector that relays multiple circuits installed across multiple terminal devices and has a terminal-side relay structure that is distributed and independent for each circuit. A flat cable that is placed on the printed circuit board and printed circuit board to connect the circuit on the control device side. Connector and terminal side relay structure are provided to provide the address corresponding to the address of each signal line of the flat cable corresponding to each contact of the flat cable connector, and the flat cable connector to each terminal of the terminal side relay structure. An address corresponding to the address of each contact of is given, and each address of the flat cable connector Display that connects each terminal of the terminal side relay structure with wiring formed on the printed circuit board, while displaying the address of each terminal of the terminal side relay structure in or near the terminal side relay structure in an arrangement corresponding to the arrangement of each terminal Means are provided.

[0010]

[Action]

 By using a printed circuit board to connect each contact of the flat cable connector to each terminal of the terminal-side relay structure, each contact of the flat cable connector and each terminal of the terminal-side relay structure that constitute the control-side relay structure And are connected correspondingly without error. This eliminates the need for addressing the control connection side contact and control side connector while checking the control side connection wire number and the drawing.

Further, each terminal of the terminal-side relay structure is correctly addressed for each circuit. Since this address is displayed by the display means provided in the terminal side relay structure or in the vicinity thereof, the address of each terminal can be easily confirmed by looking at this display means.
