Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a control panel that accommodates a group of devices for controlling various electrical devices.

(Prior Art) Conventionally, when a large number of electrical devices are to be controlled, it has been common practice to install a large number of control panels side by side. In this case, a large number of conductive wires, such as a conductive wire connected to a power source such as an operating power source, and a conductive wire connected to an alarm, are commonly connected between the control panels. For this reason, a common bus bar is wired between the control panels and is connected to a terminal block provided in each control panel. In each control panel, conductive wires are led from this terminal block to a plurality of equipment groups that respectively control different electrical equipment.

However, with conventional bolt-tight terminal blocks,
Connecting and disconnecting the wires is difficult, and connections are likely to be made incorrectly. Furthermore, connection lines cannot be made in advance, and wiring must be done each time at the installation site. Further, when a design change occurs, there is an inconvenience such as having to rewire the wiring each time.

(Problems to be solved by the invention) Therefore, the invention makes it easy to attach and detach electric wires, makes connection mistakes less likely, and improves quality. The challenge is to provide a control panel that does not require complicated wiring work at the installation site.

(Means for solving the problem) In this invention, in order to solve the above problem,
A plurality of devices related to one circuit to be controlled are assembled, and a plurality of device aggregates 1 for each circuit are mounted on a mounting plate 2.
In the control panels installed in at least one row above, the first connection terminals 4 are connected to the ends of the connection wires 3 common to each equipment assembly 1, and the first connection terminals 4 are connected to the sides of each equipment assembly 1. , first fixed Faston terminals 5 for connecting the first connection Faston terminals 4 are attached, and two sets of conducting wires 6 and 7 are drawn out from these first fixed Faston terminals 5, respectively, and connected to both sides. It is connected to another adjacent first fixed Faston terminal 5, and a second connecting Faston terminal 8 is connected to the tip of a set of conductive wires 7 of the first fixed Faston terminal 5 on one end side. A second fixed Faston terminal 9 for connecting the second connection Faston terminal 8 is attached to a position near the second connection Faston terminal 8, and from this second fixed Faston terminal 9, two sets of conducting wires are connected. 10 and 11, and connect the third fixed Faston terminal 12 for board-to-panel crossing to the tip of one set of conductor wires 10 and fix it. A third connection Faston terminal 13 for connection to a third fixed Faston terminal of another control panel
connected.

(Function) In the control panel of the present invention, by removing the first connection Faston terminal 4 from the first fixed Faston terminal 5, the common line can be removed regardless of other circuits. When dividing adjacent panels, it is only necessary to remove the third connecting Faston terminal 13 from the third fixed Faston terminal 12, and restoration is easy. By removing the second connection Faston terminal 8 from the second fixed Faston terminal 9, the common line can be removed regardless of other control panels.

(Example) An example of the present invention is shown in FIGS. 1 to 4.
Figure 1 is a front view schematically showing multiple control panels;
Figure 2 is a front view of the control panel, Figure 3 is Figure 2-
The sectional view and FIG. 4 are perspective views of the Faston terminal in an attached state.

In Figure 1, three control panels A, B, and C placed adjacent to each other control multiple devices related to one circuit, such as magnetic switches, circuit breakers, current transformers, and auxiliary relays. The assembly 1 is mounted on a mounting plate 2 in a vertical line. In this embodiment, the mounting plate 2 is divided for each equipment assembly 1.

First connection terminals 4 are connected to the ends of the connection lines 3 that connect to the required devices in each device assembly 1, respectively. A first fixed Faston terminal 5 for connecting the first connection Faston terminal 4 is attached to the side of each equipment assembly 1. Two sets of conducting wires 6 and 7 are drawn out from these first fixed Faston terminals 5, respectively.
Through the back surface of the substrate 2, other first
The fixed Faston terminals 5 are connected to each other, and each fixed Faston terminal 5 is connected to the fixed Faston terminals 5 by conductive wires 6 and 7. However, a second connection Faston terminal 8 is connected to the tip of the set of conductive wires 7 of the fixed Faston terminal 5 located at the lower end.

A second fixed Faston terminal 9 for connecting the second Faststone terminal 8 is attached near the second Faststone terminal 8 for connection. From this second fixed Faston terminal 9, two sets of conducting wires 10, 11 are connected.
is pulled out, and at the tip of one set of conducting wires 10,
A third fixed Faston terminal 12 for board-to-panel crossing is connected and fixed to the lower part of the control panel. A third faston terminal 13 for connection is connected to the tip of the other set of conductive wires 11 for connection to a third fixed faston terminal 12 of another adjacent control panel. However, control panel A located on one end side
The conductive wire 11' of the Faston terminal 9 is connected to a bus terminal block D outside the panel, and is connected to a power source, an operating power source, an alarm circuit, a relay circuit, etc. via this. Therefore, all the necessary equipment of control panels A, B, and C will be connected to the operating power supply (AC X, Y, DC P, N), alarm circuit (AL), relay circuit (Ry), etc. Become.

Next, a more specific mounting structure will be described with reference to FIGS. 2 and 3. Mounting rails 14 are provided upright and in parallel within the control panel. A plurality of mounting plates 2 are mounted on the mounting rail 14 in a row in the vertical direction at intervals from each other. Therefore, a wiring space is formed on the back surface of the mounting plate 2, and the conductive wires 6 and 7 are routed through this space. Mounted on one mounting plate 2 is an assembly 1 of a plurality of devices related to one circuit to be controlled, such as a magnetic switch, a circuit breaker, a current transformer, and an auxiliary relay. Reference numerals 15 and 16 are wiring ducts for wiring operation lines, and the rails 1 are arranged so as to surround and divide each equipment assembly.
4 via a spacer.
Further, a first fixed Faston terminal 5 is attached to the side between the upper and lower mounting plates 2. That is, the fixed Faston terminal 5 is located on the side of the vertical duct 15 and is fixed on the rail 14 via the mounting frame 17. A first connecting terminal 4 is separably connected to the fixed terminal 5 .

Second and third fixed Faston terminals 9 and 12 are attached to the lower part of the rail 14 via a dual attachment frame 18.

In the control panel of this embodiment, since the conductive wires 6 and 7 are wired on the back side of the board, it is possible to leave an allowance in length, and even if the dimensions of the board 2 are slightly different, they can be flexibly adjusted. We can respond. Since the width of the board is predetermined, it is possible to perform wiring and Faston terminal connection work at another location before assembling the board, which is efficient. By removing the first connection Faston terminal 4 from the first fixed Faston terminal 5, the common line can be removed regardless of other circuits. When dividing adjacent panels, it is only necessary to remove the third connecting Faston terminal 13 from the third fixed Faston terminal 12, and restoration is easy. By removing the second connection Faston terminal 8 from the second fixed Faston terminal 9, the common line can be removed regardless of other control panels.
