In the figure, 1 is a housing, 2 is a control CPU unit housed in the housing 1, 3 is a process input / output unit (hereinafter abbreviated as PIO unit) connected to the control CPU unit 2, and 4 is a PIO unit. A process input / output card (hereinafter abbreviated as PIO card) housed in 3
It is provided with a connection plug receiver 4a that can be connected to the outside. Reference numeral 5 denotes a terminal block attached to the housing 1, which has a plurality of internal connection terminals 5a and external connection terminals 5b as shown in FIG. A cable 6 connects between the PIO card 4 and the terminal block 5, one end of which is connected to the connection plug receiver 4a and the removable connection plug 7.

Next, the operation will be described. Regarding the internal connection of the digital controller configured as described above, one end of the cable 6 is connected to the PIO card 4 and the removable connection plug 7, and the other end of the cable 6 is a terminal for internal connection of the terminal block 5.
5a is connected according to an input / output signal.

[0004]

As described above, in the conventional internal connection device, the cable 6 connected to the control device 4 is directly connected to the terminal block 5, so that one internal connection cable 6 is connected to one external terminal. The main connection is made, and the number of connected cables 6 increases in proportion to the number of points of connection with the outside. For this reason, the connection work becomes complicated and the man-hours for the connection work increase, so that there are problems in that defects increase in proportion to the number of cables 6 and the test period becomes long.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an internal connecting device which can reduce the number of connecting steps and prevent problems.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has a terminal having a connection plug receiver fixed at one end and a terminal connectable to the outside at the other end, and a connection plug receiver. And a connection cable having a prefabricated cable composed of a plurality of cables connected to the connection plug receiver and the removable connection plug, respectively. .

[0007]

In the terminal board of the internal connection device according to the present invention, the terminal and the connection plug receiver are electrically connected by the connection wiring pattern.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a block diagram showing a digital controller using an internal connection device according to a first embodiment of the present invention, and FIG. 2 is a block diagram showing details of a terminal board in the digital controller of FIG. In each figure, 1 to 4 and 7 are the same as the conventional ones, and therefore the description thereof is omitted. 8 is a plurality of connection wiring patterns
The substrate 8a is formed and is attached to the housing 1. 9
Reference numeral 10 denotes a connection plug receiver connected to one end of the connection wiring pattern 8a and fixed to the substrate 1, and 10 denotes a plurality of external connection terminals respectively connected to the other end of the connection wiring pattern 8a, which are formed to be connectable to the outside. There is. Then, the terminal plate 11 is formed by the above 8 to 10. Reference numeral 12 is a prefabricated cable composed of a plurality of electric wires, to one end of which a connection plug receiver 4a of the PIO card 4 and a removable connection plug 7 are connected. Reference numeral 13 is a connection plug that is connected to the other end of the prefabricated cable 12 and is removable from the connection plug receiver 9 of the terminal plate 11. A connection cable 14 for connecting the PIO card 4 and the terminal board 11 is formed by the above 7, 12, and 13.

Next, the operation will be described. In the digital control device using the internal connecting device configured as described above, the prefabricated cable 12 connecting between the connection plugs 7 and the connection plugs 13 at both ends of the connection cable 14 compares the cable numbers and according to the circuit. The device (PIO unit) 4 and the terminal board 11 are connected by being connected to the number pins of the connection plugs 7 and 13 and connecting the connection plugs 7 and 13 to the connection plug receivers 4a and 8.

In the connection device of the first embodiment configured as described above, the plurality of cables 12 are connected by comparing the cable numbers with the pin numbers of the connection plugs 7 and 13, so that the work procedure can be established. Since the connection error is prevented and the terminal board 10 is connected between the connection plug receiver 9 and the external connection terminal 10 by the connection wiring pattern 8a, the effect of preventing erroneous connection can be obtained.

Embodiment 2. If the terminal boards 11 are stacked and arranged by an appropriate means, the same effect as that of the above-described embodiment can be exhibited, and the effect of increasing the wiring capacitance can also be obtained.

[0012]

As described above, according to the present invention, the terminal having the connection cap receiver fixed to one end and the terminal connectable with the outside at the other end, and the pattern for connecting the connection cap receiver and the terminal are respectively formed. Since it is configured to have a pre-fabricated cable consisting of multiple cables connected to the terminal board and the connection plug receiver and the removable connection plug, the number of steps for internal connection is reduced and miswiring is prevented. The effect that can be obtained is obtained.
