SOLUTION: The wiring work is streamlined by forming a DC24 V line 11 and a 0 V line 12 with conductive tapes on a DIN rail 1 laid in advance, by providing conductive claws 1A that electrically contact the lines slidably, and by connecting different equipment, including a power-supplying device by these claws 1A.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a wiring saving structure for a control panel.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional example. (A) is a front view, and (b) is a side view. Conventionally, when a control panel or the like has a reduced wiring structure, for example, as shown in FIG.
(German Industrial Standard) It is known that a power supply 2 and a control device 3 are installed on a rail 1 well-known as a rail, and these are connected by a crossover wiring L at a terminal block 3A or the like. Although FIG. 5 shows only the terminal block 3A of the control device 3, it is assumed that the power supply 2 is similarly provided with a terminal block.
In addition, since there are many types of control devices 3 that supply 24 V DC, the crossover wiring L is a 24 V DC line. 1A is a conductive claw provided on the control device 3, whereby the power supply device 2 and the control device 3 are electrically connected to each other.

[0003]

However, there is a problem that the above-mentioned conventional method requires a work for mounting on a DIN rail and a work for crossover wiring. In addition, there is a problem such as device destruction due to reverse connection (incorrect wiring). Accordingly, an object of the present invention is to eliminate the need for a work for mounting on a DIN rail and a work for crossover wiring, and to eliminate erroneous wiring.

[0004]

In order to solve such a problem, according to the first aspect of the present invention, a 24V DC line and a 0V line made of a conductive tape or an AS-line are mounted on a DIN rail previously laid on a control panel. i + line and A
An S-i-line is formed, and various devices including a power supply device are connected to each line made of a conductive tape via a contact member that slides electrically.

According to the first aspect of the invention, the contact member is a conductive piece or a metal piece, which can be pressed and fixed with screws from the front side of the device (the invention of claim 2), or The contact member can be an attachment that can be attached to the terminal blocks of the various devices (the invention of claim 3). In any one of the first to third aspects of the present invention, a plurality of the DIN rails are provided.
When connecting the IN rails, the connection can be made by a connector (the invention of claim 4).

[0006]

FIG. 1 is a block diagram showing a first embodiment of the present invention, in which a power supply is 24 V DC. 1A is a front view, FIG. 1B is a rear view, and FIG. 1C is a side view. As is clear from the figure, the feature is that the DC 24 V line 11 and the 0 V line 12 are provided on the DIN rail 1, thereby eliminating the need for the crossover wiring as shown in FIG. At this time, each of the lines 11 and 12 is formed by attaching a conductive tape to the DIN rail 1 here. When the DIN rail 1 is made of an insulating member, the conductive tape is attached as it is and the DIN rail 1 is attached.
When the rail 1 is made of a conductive member, the rail is insulated once and then a conductive tape is attached. 1A is a conductive nail as in FIG.
The power supply device 2 and the control device 3 are electrically connected to each other via the claw 1A.

FIG. 2 is a structural view showing a second embodiment of the present invention. FIG. 2 (a) is a front view, FIG. 2 (b) is a rear view, and FIG. 2 (c) is a side view. This uses a metal piece or a conductive piece 1B instead of the nail 1A as a contact member in FIG.
This is pressed and fixed with a screw 4 to supply a power supply or a transmission signal. At this time, the work is facilitated by pressing and fixing the metal piece or the conductive piece 1B by the screw 4 from the front side of the control device 3.

FIG. 3 is a structural view showing a third embodiment of the present invention. FIG. 3 (a) is a front view, and FIG. 3 (b) is a rear view. The difference is that an attachment 1C capable of connecting the terminal blocks 2A and 3A of the power supply 2 and the control device 3 to the DIN rail 1 is used instead of the claw 1A or the metal piece or the conductive piece 1B as the contact member. Only the rest is the same as FIG.

FIG. 4 is a block diagram showing a fourth embodiment of the present invention, and shows only a front view. This is DIN rail 1
Shows a case where there are a plurality of (two in the figure). In such a case, D
By connecting the IN rails 1 with a connector 5, for example, the number of wiring steps is reduced. Here, an example is shown in which the present invention is applied to a device using the attachment 1C as the contact member, but it goes without saying that the present invention can be similarly applied to the case of FIGS. 31A indicates a terminal block of the device 31.

By the way, in Europe, an open network AS-i (actuator sensor-integer) that realizes wiring reduction mainly by Siemens.
rface) is adopted. This AS-i is known as a bit-level wiring-saving network for connecting sensors and actuators.
It is composed of an i-substrate unit (AS-i communication unit) and an AS-i cable unit, but the present invention can be similarly applied to such an AS-i system. That is, FIG.
To AS-i + lines, lines 11 and 12 shown in FIG.
It can be used as an AS-i-line.

[0011]

According to the present invention, there is no need to perform a wiring work for a 24 V DC line or an AS-i line, so that wiring in the control panel can be reduced, and equipment due to wiring mistakes such as reverse connection. And the like can be prevented.
