Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a light distribution switchboard type agreement breaker for wiring (JIS C).
The present invention relates to a device in a panel such as 8370 Annex 5), and particularly to improvement of a terminal cover thereof.

[0002]

2. Description of the Related Art A conventional agreement type circuit breaker is shown in FIGS.
Will be described. 5 is a perspective view showing a state in which the terminal cover is removed, and FIG. 6 is a side view showing a state in which the terminal cover is opened.

In the figure, 1 is a distribution board, 2 is a door of the distribution board 1, 3 is a mounting rail provided inside the distribution board 1,
4 is a breaker for a contract type wiring arranged in the distribution board 1 by the mounting rails 3, 5 is a circuit breaker housing, and 6 is a projecting portion provided in a step shape on the front surface 5a of the circuit breaker housing 5. , This protrusion 6
The display unit and the operation unit configured as described above are exposed from the opening 2a of the door 2. Reference numeral 7 denotes a terminal block provided on the front surface 5a along the side surface proximal end side of the projecting portion 6, and a terminal screw 7a screwed by a driver 8 from the front surface side is arranged. Reference numeral 9 is a connecting lead wire that is connected to the terminal screw 7a by inserting and removing it from the side, and 10 is a terminal cover of the terminal block 7, which is opened to the side surface 6a side of the protrusion 6 with the pivot shaft 10a as a fulcrum. ing. Reference numeral 11 denotes a stopper projection provided on the side surface of the terminal cover 10, which is adapted to engage with the stopper hole 12 of the breaker housing 5 when closed. Reference numeral 13 is a bearing hole of the circuit breaker housing 5 that rotatably supports the pivot shaft 10a of the terminal cover 10.

As shown in FIG. 6, the terminal cover 10 is opened and closed by using the pivot shaft 10a as a fulcrum, and in the closed state, the locking projection 11 engages with the locking hole 12 and is fixed to the breaker housing 5. There is. After opening the door 2, the terminal cover 10 is opened and the lead wire 9 is connected by the driver 8.

[0005]

In the conventional in-panel equipment as described above, as shown in FIG. 6, the outer surface of the terminal cover 10 hits the side surface 6a of the projecting portion 6 and opens only about 90 degrees, so that the driver 8 Therefore, it is difficult to connect the lead wires 9, and if the terminal cover 10 is removed from the circuit breaker housing 5 as shown in FIG. 5 during the connecting work, the removed terminal cover 10 may be lost even if the work is easily performed. There was a problem.

The present invention has been made in order to solve the above-mentioned problems, and facilitates the wiring work by opening the terminal cover by 180 degrees, and at the same time, provides an in-panel device which eliminates the loss of the terminal cover. The purpose is to get.

[0007]

The equipment in the panel according to the present invention is detachably attached to the front with a protruding portion provided in a stepwise manner on the front so that the display portion and the operation portion are exposed on the panel, as a separate body. When the terminal cover is opened and the lead wire is connected, the projecting portion is removed from the front so that the terminal cover is opened 180 degrees. Further, a terminal name plate is provided on the inner surface of the terminal cover.

[0008]

In the present invention, by removing the projecting portion, the terminal cover can be opened 180 degrees to the front after removing the projecting portion. Further, by opening the terminal cover 180 degrees, the terminal name plate on the inner surface of the terminal cover can be easily seen from the front.

[0009]

EXAMPLES Example 1. 1 and 2 showing an embodiment of the present invention.
Will be described. FIG. 1 is a perspective view showing a state where a projecting portion and a terminal cover are removed, and FIG. 2 is a side view showing an opening / closing operation of the terminal cover. The description is omitted. In the figure, 6
A is a projecting portion formed separately on the front surface 5a of the circuit breaker housing 5, and can be detached from the front surface 5a of the circuit breaker housing 5 by engaging the locking claw 14 with the locking recess 15 of the front surface 5a. It is different from the conventional protrusion 6 in that it is attached to the. Reference numeral 16 is a fixing hole provided in the circuit breaker housing 5, and the fixing projection 11 of the terminal cover 10 opened 180 degrees is engaged with the fixing hole 16.

When the terminal cover 10 is opened to perform the wiring work, the projecting portion 6A is removed from the front surface 5a of the circuit breaker housing 5 as shown in FIG. By doing so, the terminal cover 10 opened as shown by the phantom line in FIG.
Since it can be opened 180 degrees to the front surface 5a after the removal, the terminal cover 10 does not get in the way, and the connection work can be performed easily. At this time, the terminal cover 10 does not have to be removed from the breaker housing 5, so there is no risk of loss.

The projection and the hole are arranged in the opposite manner, that is, the pivot shaft 10a on the side of the terminal cover 10 and the stopper projection 1 are provided.
1 to the circuit breaker housing 5 side, and the bearing hole 13 of the circuit breaker housing 5
And the fixing hole 12 (also the fixing hole 16) to the terminal cover 10.
Even if it is provided on the side, the same operation as described above is performed.

Example 2. When the fixing hole 16 is provided in the circuit breaker housing 5 as shown in FIGS. 1 and 2 in the first embodiment, the terminal cover 10 is provided as shown by an imaginary line in FIG.
Since it can be fixed to the 0 degree open state, the wiring work can be performed more easily.

Embodiment 3. As shown in FIG. 3, the terminal cover 1
If the terminal name plate 17 is attached to the inner surface of 0, the terminal name plate 17 can be seen easily from the front when the terminal cover 10 is opened 180 degrees, which facilitates the wiring work.

Example 4. As shown in FIG. 4, when the terminal name plate 17 is attached to the front surface 5a of the circuit breaker housing 5 after the protruding portion 6A is removed and the terminal cover 10 is a transparent terminal cover 10A made of transparent resin, the transparent terminal cover 10A 18
When opened at 0 degrees, the terminal name plate 17 can be seen from the front through the transparent terminal cover 10A, which facilitates connection work.

Example 5. In the fourth embodiment, instead of the attached terminal name plate 17, a terminal symbol or the like may be printed on the front surface 5a of the circuit breaker housing 5.

In the above description, the agreement type circuit breaker is shown as the in-panel device, but it can be widely applied to electronic devices having an electronic circuit built therein, and the circuit breaker 4 is laterally attached in the illustrated description. It may be installed vertically. When a large number of devices are arranged side by side in the distribution panel in a vertically mounted state, the same effect can be obtained especially when they are close to or adjacent to the wall.

[0017]

As described above, according to the present invention, since the terminal cover is opened 180 degrees, the connection work can be performed easily, and the terminal cover does not have to be removed, so that the terminal cover is not lost. Be done.
