Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a control panel that supplies power to power equipment.

[Background technology]

FIG. 1 shows a perspective view of a control panel main body 1 that supplies power to power equipment, and FIG. 2 shows a perspective view with the door 2 open. The control panel main body 1 is composed of a box 9 with an open front, and a door 2 which is pivoted to a part of the box 9 by a hinge 10 and can be opened and closed. Inside the box 9 are a main power breaker 3 and an electromagnetic switch 4 that supply power to power equipment such as motors.
A plurality of main circuit units A, each of which is formed into a unit, are arranged in the vertical direction. A vertically long window hole 14 is bored in the right end of the door 2, and a plurality of operation display units B, each unitized, are arranged in the window hole 14 in the vertical direction from the back side of the door 2. These operation display units B have the same or different functions and are configured as follows. 11 is a power lamp of the control panel body 1 itself; 5 is an operation button for turning on and off the electromagnetic switch 4 for driving a motor, etc.; and 6 is a meter for displaying the status of the load such as the motor in terms of voltage or current. 13
is a changeover switch. A buzzer unit 8 is arranged below these operation display units B to notify of abnormalities in the load. 7 is a buzzer stop button. Reference numeral 17 denotes a connection cord that connects the unit A inside the box body 9 with each operation display unit B and the buzzer unit 8 on the door 2, and each unit A side inside the box body 9 is connected by a connector 16. . In addition, the connection cord 17 part on the back side of the door 2 is connected to the second
As shown in the figure, bundle the wires with a bundle band, etc., and
Each operation display unit B was connected sequentially. However, in such a case, with door 2 open,
There was a problem that the connection cord 17 was visible and spoiled the aesthetic appearance. Further, since many operation display units B are attached to the door 2, there is a problem that the door 2 may be deformed if the plate thickness is thin. 15 is a handle.

[Purpose of invention]

The present invention has been proposed in view of the above-mentioned points, and it is an object of the present invention to provide a control panel that covers the connection cord on the back side of the door with a wiring duct and also serves as reinforcement for the door.

[Disclosure of invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Note that the overall configuration is the same as that of the conventional example. As shown in Figure 3, a metal wiring duct 1 with a U-shaped cross section
8 is arranged on the side of the window hole 14 along the vertical direction of the window hole 14. The length of the wiring duct 18 is approximately the same as the length of the window hole 14 in the vertical direction, and the opening side is connected to the window hole 14 corresponding to each operation display unit B.
One side piece 18a is fixed to the back surface of the door 2 by spot welding (points x in the figure).

Note that the edge of the window hole 14 is bent inward in a substantially U-shape as shown in FIG.
Forms a mounting piece 2a to which the mounting piece 2a is attached.
A wiring duct 18 is attached with the opening facing a. In this embodiment, the connection cord 17 is housed in the wiring duct 18 and connected to each operation display unit B in sequence. Therefore, this wiring duct 18 allows the connection cord 17 to be housed and wired, and
Since it is fixed by spot welding in the vertical direction, it can also serve as reinforcement for the door 2.

[Effect of idea]

As mentioned above, the present invention is to attach a metal wiring duct with a U-shaped cross section to the side of the window hole on the back side of the door, with the opening facing the mounting piece, that is, facing the operation display unit, and this wiring The connection cord that connects the main circuit unit on the box side and the operation display unit on the door side is stored inside the duct, so when the door is opened, the connection cord on the back of the door is visible and does not spoil the aesthetics. Moreover, by attaching a metal wiring duct to the door, it can also serve as reinforcement for the door itself, and even if a door with a thin plate is used, it will not be deformed. Furthermore, since the opening of the wiring duct is open to the operation display unit side, the connection cord can be easily accommodated in the wiring duct, and the edge of the window hole that exposes the operation display unit can be turned inward in a roughly U-shape. A mounting piece is formed by bending it into a shape to attach the operation display unit, and the wiring duct is attached to this mounting piece with the openings facing each other, so a part of the wiring duct is blocked by the mounting piece and the connection cord cannot be connected. This has the advantage of reducing the number of escapes.

[Brief explanation of drawings]

Fig. 1 is a perspective view of the control panel main body of the conventional embodiment, Fig. 2 is a perspective view showing the same door opened, Fig. 3 is a perspective view of the embodiment of the present invention, and Fig. 4 is It is an enlarged main part plan view same as the above. 1 is the control panel body, 2 is the door, 2a is the mounting piece, 3 is the breaker, 4 is the electromagnetic switch, 5 is the operation button, 6 is the meter, 9 is the box body, 14 is the window hole, 16 is the connector,
17 is a connection cord, 18 is a wiring duct, A is a main circuit unit, and B is an operation display unit.

Claims (1)

[Scope of utility model registration request] The main body of the control panel is formed by a box with an opening at the front and a door pivoted to the opening of the box so that it can be opened and closed. Inside the box, there are main power supply side breakers that supply power to loads such as power equipment, etc. A main circuit unit consisting of an electromagnetic switch, etc. is installed, and an operation display unit consisting of an operation button for operating the electromagnetic switch and a meter for displaying the load status is installed on the door, and an operation display unit is installed on the door. A window hole is formed to expose the unit, and the edge of the window hole is bent inward in a substantially U-shape to form a mounting piece for attaching the operation display unit, and the opening is opposed to the mounting piece. A metal wiring duct with a U-shaped cross section is attached to the side of the window hole on the back side of the door, and the connection cord that connects the main circuit unit on the box side and the operation display unit on the door side is stored inside this wiring duct. control panel.
