DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring module.

[0002]

2. Description of the Related Art In recent years, automation of machine tools, processing machines, assembling machines and the like has been rapidly promoted in order to eliminate labor shortages. In order to automate these machines, a large number of sensors are arranged at and around each part of the machine, and these sensors are connected via input signal lines to, for example, a sequencer, a programmable controller (hereinafter abbreviated as PC), or the like. Power supply for connecting a controller of an electromagnetic valve via an output signal line to the controller, and for driving a sensor, a driver, etc. (hereinafter, individually or collectively referred to as an external device). And each external device with a power line.

As these wiring methods, for example, as shown in FIGS. 14 and 15, a signal line 102a and a pair of power lines 102b of a fixed length are led out from a large number of sensors 101, and the leading ends are led out. A system is used in which the relay 103 is connected to a relay signal line 104 and a pair of relay power lines 105 via a connector 103, and then connected to a controller 107 and a power supply 108 via a relay terminal block 106. As shown in FIG. 15, the relay signal line 104
The relay power supply wires 105 are bound at appropriate intervals, and the number of the bound wires gradually increases as approaching the relay terminal block 106.

[0004]

By the way, the above-mentioned sensor
Each of the external devices such as 101 is not concentrated at one place, but is mounted at a required position. For this reason,
A large number of wirings connected to each external device distributed over a considerably wide area are concentrated near the relay terminal block. Therefore, in this type of conventional wiring, there is a problem that erroneous wiring due to an incorrect connection to the relay terminal block, and failure or damage of the equipment due to the erroneous wiring are likely to occur.

Further, since a large number of wires are concentrated near the relay terminal block, it is necessary to confirm the correspondence of wiring when connecting each line to the relay terminal block. It cannot be done by division of labor. further,
The thickness of the lead wire for each external device is not constant, and a thick wire and a thin wire are mixed at a place where the wires are bound. For this reason, disconnection may occur when a lead wire or the like is routed inside a machine tool or the like.

In addition, since each external device has a lead wire of a fixed length except in special cases, a connector is required for each external device, and a connector is connected for each external device. This is disadvantageous in improving the workability of the connection work, and a large number of connectors are scattered in the middle of the wiring, particularly in the binding portion and in the vicinity thereof, so that maintenance of each external device becomes difficult and it is difficult to perform the binding portion. The product's aesthetic appearance is significantly impaired.

And the flat cable 60b connected to the output section O of the PC, there is almost no possibility that both flat cables on the PC side are incorrectly connected to the PC. Further, both flat cables 60b on the controller side are connected to input signal circuits and output signal circuits of the printed wiring board 23 via control side connectors 21a and 21b, respectively, and these input signal circuits and output signal circuits are respectively connected to a plurality of external devices. Connected to the plurality of flat cables 60b on the external device side via the side connectors 22a and 22b, so that each input signal line of the flat cable 60b on the controller side and each input signal line of both flat cables 60b on the external device side are connected to each other. And the correspondence between the output signal lines of the middle flat cable 60b on the controller side and the output signal lines of both flat cables 60b on the external device side does not cause errors.

Errors can be almost completely eliminated, and failure or damage of the external device 90 or malfunction of the PC due to an error in the correspondence can be prevented. In addition, wiring work between the wiring modules 10 (or 20), 40, and 50 can be prevented. In addition, the wiring work on the control side of the wiring module 10 and the wiring work from each of the wiring modules 40 and 50 to the external device 90 can be separately performed.

Further, each of the external device connection connectors 10, 40,
