SOLUTION: A slide rail 9 that slides on a slide base 8 is provided inside a box 4, and the front panel 1 is structured at the end of the slide rail 9 via a hinge 6, in such a way as to be turnable so that the front panel is turned in a drawn-out state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switchboard, and more particularly to an improvement in the structure of a front panel.

[0002]

2. Description of the Related Art A front view of a conventional switchboard is shown in FIG. In the figure, 1 is a front panel, 2 is an electric component, and 3 is a fixing screw. FIG. 5 is a view taken in the direction of arrows AA in FIG. As shown in the figure, an external terminal block 5 for connecting various units and other devices is provided inside the housing 4. Front panel 1 is hinge 6
A handle 7 for fixing the front panel 1 so as not to open is attached to the front panel 1. The electric component 2 such as a test terminal is attached to an inner surface of the front panel 1.

[0003] The handle 7 is turned to move the front panel 1 to the housing 4.
6 and pivoted about the hinge 6, the state shown in FIG. 6 is obtained. This is such that the front end 4a of the housing 4 acts as a stopper so that the open front panel 1 does not contact the adjacent switchboard, and the opening of the front panel 1 is restricted. Then, work such as maintenance and inspection is performed in a portion of a work space (a) indicated by oblique lines in FIG.

[0004]

However, the electric components 2 attached to the front panel 1 hinder maintenance and inspection of the equipment in the housing 4. Also, when the device is carried out from the inside of the housing 4, the electric component 2 also hinders.

[0005] Therefore, an object of the present invention is to provide a switchboard which solves such a problem.

[0006]

According to a first aspect of the present invention, there is provided a switchboard having a housing provided with a door which can be opened and closed at an opening of the housing. Inside, a slide rail is provided that can move forward and backward from the opening toward the outside of the housing, and a door is provided on the slide rail so as to be freely rotatable. The configuration of the switchboard according to claim 2, Claim 1 is characterized in that a slide restraining means for restraining the slide rail in a state where the slide rail is moved toward the outside of the housing is provided. Or 2 is characterized in that an opening / closing restraining means for restraining the door from opening is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a switchboard according to the present invention will be described below. In this embodiment, since a part of a conventional switchboard is improved, the same parts as those in the related art are denoted by the same reference numerals, and the description thereof will be omitted. Only different parts will be described.

As shown in FIG. 1, a frame 4b is provided on the inner surface on the left side of the housing 4, and a pair of upper and lower slide bases 8 are attached to the frame 4b. Each slide base 8 is provided with a slide rail 9 that is slidable in the vertical direction in the figure, and the pair of upper and lower slide rails 9 are integrally connected by a connecting member (not shown). A ball bearing (not shown) is provided between the slide base 8 and the slide rail 9 so as to slide smoothly with a small force.

A slide restraining means 10 is provided to restrain the slide rails 9 in a state where the pair of slide rails 9 slides downward in the drawing. The slide restraining means 10 includes a stopper 4 formed on the frame 4b.
c and one end of a leaf spring 15 having one end fixed to one of the slide rails 9.
Lock pin 1 urged toward the outside of housing 4 by
1 and 1. The lock pin 11 has a tapered portion 1
1a is formed.

A side portion of the front panel 1 serving as a door is rotatably connected to a tip end of each slide rail 9 via a hinge 6. An opening / closing restricting means 12 for restricting opening / closing of the front panel 1 is provided. The opening / closing restraining means 12 includes an L-shaped angle 13 fixed to the inside of the front panel 1 and a planar latch 14a fixed to one slide rail 9 and restraining the angle 13.
And an operation unit 14 for operating the.

Next, the operation of the switchboard will be described. FIG.
When the front panel 1 is closed, the handle 7 restricts the opening and closing of the front panel 1 as shown in FIG. When opening the front panel 1, the front panel 1 is opened by the handle 7, and the front panel 1 is pulled toward the user. Then, since the pair of upper and lower slide rails 9 slide along the slide base 8, the entire front panel 1 moves forward with the slide rails 9 as shown in FIG. At this time, when an external force is applied, the front panel 1 attempts to rotate around the hinge 6, but the rotation is prevented by the action of the opening / closing restraining means 12. When the entire front panel 1 slides forward, the lock pin 11 moves downward in FIG. 2 beyond the stopper 4 c by the action of the tapered portion 11 a and the spring, and the slide rail 9 and the front panel One slide is restrained.

Thereafter, when the operation panel 14 is operated to release the restraint of the front panel 1 by the opening / closing restraining means 12 and the front panel 1 is rotated about the hinge 6, as shown in FIG. Is rotated 180 degrees until the side end near the hinge 6 contacts the slide rail 9. The front panel 1 rotates 180 degrees as shown in FIG.
The whole of the front side becomes a work space (b), so that not only the workability for maintenance and inspection but also the workability when carrying out the equipment from inside the housing 4 is good. On the other hand, since the entire front panel 1 is drawn out, the front panel 1 does not come into contact with the adjacent switchboard.

After the work is completed, the front panel 1 is
Then, the restraint of the slide rail 9 by the slide restraint means 10 is released, and the front panel 1 is pushed together with the slide rail 9. When the handle 7 restricts the rotation of the front panel 1, the state returns to the state shown in FIG.

In this embodiment, both the slide restraining means and the rotation restraining means are provided, but only one of them may be provided, or a structure in which neither is provided.

[0015]

As can be seen from the above description, claim 1
According to the switchboard according to the configuration is opened after the entire door is pulled out, so even if electrical components are attached inside the door,
The work space can be maximized without obstructing maintenance, inspection or removal of the equipment. Therefore, mounting efficiency can be improved by providing electric components inside the door.

According to the switchboard according to the second and third aspects, since the slide restraining means and the rotation restraining means are provided, the safety of work can be ensured.
