Description


本発明は、住宅や店舗などで使用される分電盤に関する。
The present invention relates to a distribution board used in a house or a store.


従来、分電盤では、例えば、特許文献１に記載されているように、壁面に取り付けられるケースのベースに主幹ブレーカや複数の分岐ブレーカなどが配設されており、それらブレーカの上下の配線スペースを通じて壁面内からベースに引き込まれる屋内配線が各ブレーカに接続される。
Conventionally, in a distribution board, as described in Patent Document 1, for example, a main breaker and a plurality of branch breakers are arranged on a base of a case attached to a wall surface, and wiring space above and below these breakers The indoor wiring drawn into the base from the inside of the wall through is connected to each breaker.


分岐ブレーカに接続する屋内配線には、２芯の電線、または２芯の電線とアース線、あるいはアース線を含む３芯の電線がある。アース線はベースの下縁部に配設されるアース中継端子に接続され、このアース中継端子を介して地面などに対してアース接続が行なわれる。
The indoor wiring connected to the branch breaker includes a two-core electric wire, a two-core electric wire and an earth wire, or a three-core electric wire including an earth wire. The ground wire is connected to a ground relay terminal disposed at the lower edge of the base, and the ground connection is made to the ground or the like via the ground relay terminal.


アース中継端子は、端子板に複数のねじ接続端子が螺合されたもので、各ねじ接続端子により屋内配線のアース線および地面などにアース接続されるアース線がそれぞれ接続される。そして、アース線を接続するには、ねじ接続端子を緩め、アース線に圧着端子を固着してねじ接続端子に取り付けるかアース線の先を丸めてねじ接続端子に取り付けた後、ねじ接続端子を締め付けることにより、アース線を接続固定する。
The ground relay terminal is formed by screwing a plurality of screw connection terminals to a terminal plate, and an earth wire for indoor wiring and a ground wire connected to the ground or the like are connected to each screw connection terminal. To connect the ground wire, loosen the screw connection terminal, attach the crimp terminal to the ground wire and attach it to the screw connection terminal, or round the tip of the ground wire and attach it to the screw connection terminal. Connect and fix the ground wire by tightening.

特開平６−３１５２１１号公報Japanese Patent Laid-Open No. 6-315211


しかしながら、従来の分電盤に用いられるアース中継端子では、ねじ接続端子のみで構成されているので、アース線を接続するためには、ねじ接続端子を緩め、アース線に圧着端子を固着してねじ接続端子に取り付けるかアース線の先を丸めてねじ接続端子に取り付た後、ねじ接続端子を締め付けなければならず、施工時の接続作業に手間がかかる問題がある。しかも、保守点検の際に、アース線を一旦外すような場合にも、同様の問題がある。

After being attached to the screw connection terminal or by rounding the tip of the ground wire and attaching it to the screw connection terminal, the screw connection terminal must be tightened. Moreover, the same problem occurs when the ground wire is once removed during maintenance inspection.


なお、分岐ブレーカに接続される屋内配線にはアース線を含む３芯の電線が多く用いられるようになってきており、この３芯の電線を分岐ブレーカに接続するのに適当な長さに切断してしまうと、アース線をアース中継端子に接続することが困難な場合がある。

As shown in FIG. 3, when the ground relay terminal 41 is attached to the terminal mounting base 25, the insertion hole 43 is closer to the inner side of the base 2 and the release button 54 is closer to the outer side of the base 2, that is, the insertion hole 43 is to the left. And a release button 54 is arranged on the right side.


次に、本実施の形態の作用を説明する。
Next, the operation of the present embodiment will be described.


分電盤の施工時には、カバー３を外した状態でベース２を壁面に固定し、壁面内の屋内配線の電線をベース２の開口部24を通じてベース２内に引き込み、主幹ブレーカ33および分岐ブレーカ34などの対応する機器に接続する。
When installing the distribution board, the base 2 is fixed to the wall surface with the cover 3 removed, and the electric wires for indoor wiring in the wall surface are drawn into the base 2 through the opening 24 of the base 2, and the main breaker 33 and the branch breaker 34 Connect to a compatible device.


分岐ブレーカ34に接続される屋内配線には、２芯の電線、または２芯の電線とアース線、あるいはアース線を含む３芯の電線などがある。それら電源用の電線やアース線は配線に適した長さに切断し、電源用の電線は分岐ブレーカ34の電線接続部34bに接続し、アース線はアース中継端子41に接続する。
The indoor wiring connected to the branch breaker 34 includes a two-core electric wire, a two-core electric wire and a ground wire, or a three-core electric wire including a ground wire. These power supply wires and ground wires are cut to a length suitable for wiring, the power supply wires are connected to the wire connection portion 34b of the branch breaker 34, and the ground wires are connected to the ground relay terminal 41.


分電盤内に引き込まれる例えば地面などにアース接続されたアース線もアース中継端子41に接続する。
An earth wire connected to the ground, for example, on the ground or the like drawn into the distribution board is also connected to the earth relay terminal 41.


これらのアース線が単線の場合には、アース線の先端を挿入孔43に前方から挿入することにより、鎖錠接続端子50でアース線を鎖錠接続する。また、アース線が撚り線の場合には、ねじ接続端子55を緩め、アース線をねじ接続端子55に絡めた後、ねじ接続端子55を締め付けてアース線を接続する。
When these ground wires are single wires, the ground wire is locked and connected by the lock connection terminal 50 by inserting the tip of the ground wire into the insertion hole 43 from the front. When the ground wire is a stranded wire, the screw connection terminal 55 is loosened, the ground wire is entangled with the screw connection terminal 55, and then the screw connection terminal 55 is tightened to connect the ground wire.


そして、配線完了後に、ベース２の前面にカバー３を取り付け、施工を完了する。
Then, after completing the wiring, the cover 3 is attached to the front surface of the base 2 to complete the construction.


また、保守点検の際などに、アース中継端子41の鎖錠接続端子50に接続されたアース線を外す場合には、リリースボタン54を前方から押動させることにより、アース線に対する鎖錠接続端子50の鎖錠を解除させ、この状態でアース線を挿入孔43から引き抜くことができる。
Also, when removing the ground wire connected to the lock connection terminal 50 of the ground relay terminal 41 during maintenance inspection, etc., the lock connection terminal for the ground wire is pushed by pushing the release button 54 from the front. 50 locks are released, and the ground wire can be pulled out from the insertion hole 43 in this state.


以上のように、アース中継端子41に鎖錠接続端子50およびねじ接続端子55の両方を備えるため、それら両方の接続方法に対応できるとともに、鎖錠接続端子50によってアース線の接続作業を容易にできる。
As described above, since the ground relay terminal 41 includes both the lock connection terminal 50 and the screw connection terminal 55, both of the connection methods can be used, and the ground wire can be easily connected by the lock connection terminal 50. it can.


また、アース中継端子41をベース２の分岐ブレーカ34の近傍の右縁部に沿って配設するため、例えば、アース線を含む３芯の電線を接続する場合に、分岐ブレーカ34に接続する電源用の電線に対してアース線を特別に長くする必要がなく、３芯の電線を一緒に切断しても、分岐ブレーカ34とアース中継端子41の両方にそれぞれ接続することができ、作業性を向上できる。なお、アース中継端子41をベース２の上縁部または下縁部に沿って配設しても同様の作用効果を得られる。
Since the ground relay terminal 41 is arranged along the right edge of the base 2 in the vicinity of the branch breaker 34, for example, when connecting a three-core electric wire including a ground wire, the power supply connected to the branch breaker 34 There is no need to make the ground wire particularly long with respect to the electric wire, and even if the three-core electric wire is cut together, it can be connected to both the branch breaker 34 and the ground relay terminal 41. It can be improved. The same effect can be obtained even if the ground relay terminal 41 is disposed along the upper or lower edge of the base 2.

また、アース中継端子41を細長い形状に形成できるため、中央部分を含む中間の主要部分を主幹ブレーカ、分岐ブレーカおよび配線等によって占有される分電盤ケースの周辺部分に配設するのに好適となる。   Also, since the ground relay terminal 41 can be formed in an elongated shape, it is suitable for disposing the middle main part including the central part in the peripheral part of the distribution board case occupied by the main breaker, branch breaker, wiring, etc. Become.

また、アース中継端子41の複数の鎖錠接続端子50を１列状に設けるとともにねじ接続端子55を鎖錠接続端子50の列の端部に設けるため、複数のアース線を複数の鎖錠接続端子50に対して接続できるとともに、端部においてねじ接続端子55を容易に操作できる。 In addition, since the plurality of lock connection terminals 50 of the ground relay terminal 41 are provided in one row and the screw connection terminal 55 is provided at the end of the row of the lock connection terminals 50, a plurality of ground wires are connected to the plurality of locks. While being able to connect to the terminal 50, the screw connection terminal 55 can be easily operated at the end.

また、アース端子板48を折曲して接続板部49を形成し、この接続板部49と鎖錠接続端子50とで鎖錠接続端子部を構成したので、構成が簡単で小形化および組立性の向上を図ることができる。   In addition, the ground terminal plate 48 is bent to form the connection plate portion 49, and the connection plate portion 49 and the lock connection terminal 50 constitute the lock connection terminal portion. It is possible to improve the performance.


また、アース中継端子41の挿入孔43をベース２の内側寄りおよびリリースボタン54をベース２の外側寄り、すなわち挿入孔43を左側およびリリースボタン54を右側に配置するため、右手でリリースボタン54の押動操作をしながら左手でアース線を引き抜く操作を行なえ、しかも、リリースボタン54を操作する際に挿入孔43に挿入されたアース線が邪魔になることがなく、リリースボタン54の操作を容易にできる。
Also, since the insertion hole 43 of the ground relay terminal 41 is located closer to the inner side of the base 2 and the release button 54 is closer to the outer side of the base 2, that is, the insertion hole 43 is located on the left side and the release button 54 is located on the right side. You can pull out the ground wire with your left hand while pushing, and the ground wire inserted into the insertion hole 43 does not get in the way when you operate the release button 54, making it easy to operate the release button 54 Can be.


また、アース中継端子41の挿入孔43をベース２の前面側に向けて設けるとともに、リリースボタン54を前方から操作可能に設けているため、アース線の挿脱を前面方向から容易にできる。
In addition, since the insertion hole 43 of the ground relay terminal 41 is provided toward the front side of the base 2 and the release button 54 is provided so as to be operable from the front, it is possible to easily insert and remove the ground wire from the front direction.
