Description

[0001]
[Industrial application fields]
The present invention relates to a ground relay terminal of a residential distribution board used in a house or the like.
[0002]
[Prior art]
Conventionally, the earthing relay terminal of a distribution board has a plurality of screw terminals screwed onto a terminal plate fixed to the case of the distribution board, and each screw terminal is connected to an earth ground wire and the ground, etc. Were connected respectively. To connect the ground wire, loosen the screw on the screw terminal and attach a crimp terminal to the ground wire or round the tip of the ground wire and attach it to the screw terminal, and then tighten the screw on the screw terminal. The wire was connected.
[0003]
Some of the ground relay terminals have screwless terminals in addition to screw terminals.
[0004]
[Problems of the prior art]
However, the conventional relay terminal of the distribution board has the following disadvantages.
[0005]
For screw terminals, connect the ground wire by loosening the screw of the screw terminal and either attaching a crimp terminal to the ground wire or rounding the tip of the ground wire and attaching it to the screw terminal, and then tightening the screw of the screw terminal It was necessary and spent a lot of time for connection work.
[0006]
In addition, since the ground relay terminal is fixed to the distribution board case for both the screw terminal and the screwless terminal, the ground relay terminal can connect the ground wire drawn into the distribution board from a position far from the ground relay terminal. It was necessary to route to a certain position, and the ground wire had to be extra long.
[0007]
OBJECT OF THE INVENTION
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a ground relay terminal for a distribution board that can easily connect a ground wire in a short time.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the ground relay terminal of the distribution board according to claim 1 is:
Conductive portion is covered with an insulating member so as not to be exposed, and is configured to have a plurality of terminals electrically connected to each other includes no more than one screw terminals, mounted on the distribution board case and the case Between the branch mounting plate
A distribution board that is arranged by connecting the ground wire that is drawn into the distribution board through the wiring hole provided in the case, and that is supported by only the connected ground wire without being fixed in the distribution board. It is configured to fit within.
[0009]
A ground relay terminal of the distribution board according to claim 2 is a hole portion through which a binding band or the like is inserted into a base made of an insulating member of the ground relay terminal in the ground relay terminal of the distribution board according to claim 1. Provide a hook with
Ru Ah which was to connect to an appropriate position in the panelboard by the binding band that transmural interpolated into the hole and an available said hook of said branch mounting plate.
[0010]
[Action]
With the above means, in the present invention, the terminal of the ground relay terminal is a screwless terminal, so that the screw loosening and tightening required when connecting the ground wire to the conventional screw terminal and the crimp terminal to the ground wire are performed. The work of mounting and rounding the tip of the ground wire can be omitted, and the ground wire can be connected in a short time.
[0011]
Furthermore, the ground relay terminal can be moved freely by not fixing the ground relay terminal in the distribution board, and the ground wire can be connected at the position where the ground wire is drawn into the distribution board. This eliminates the trouble of routing the ground wire in the distribution board.
[0012]
In addition, since the ground relay terminal is covered with an insulating member so that the conductive portion is not exposed, there is no possibility that the conductive portion of the ground relay terminal contacts the metal part in the distribution board. It can be stored in an appropriate position.
[0013]
Since the ground relay terminal is provided with a hook, the ground relay terminal can be connected to an appropriate position in the distribution board with a binding band or the like, so that the ground relay terminal can be surely accommodated in the distribution board.
