Provided with a protruding portion.

図3は、本発明の第三の実施形態の2極回路遮断器を説明するための該2極回路遮断器の負荷側端子部の方向から臨んだ斜視図である。前述した第一、第二の実施形態の2極回路遮断器と比較して、電線接続防止手段の構成が異なる。 FIG. 3: is the perspective view which faced from the direction of the load side terminal part of this 2 pole circuit breaker for demonstrating the 2 pole circuit breaker of 3rd embodiment of this invention. Compared with the two-pole circuit breaker of the first and second embodiments described above, the configuration of the wire connection preventing means is different.

図3における電線接続防止手段72は、前記電線挿入孔に差し込まれて使用される差し込み部が形成されて構成されるが、第一の実施の形態では2極両方の電線挿入孔に差し込んで設けるのに対して、片極の電線挿入孔に差し込んで使用する。 The wire connection preventing means 72 in FIG. 3 is formed by forming an insertion portion that is used by being inserted into the wire insertion hole. In the first embodiment, the wire connection prevention means 72 is provided by being inserted into both the two-pole wire insertion holes. In contrast, it is used by inserting it into a single-pole wire insertion hole.

図4は、本発明の第四の実施形態の2極回路遮断器を説明するための該2極回路遮断器の負荷側端子部の方向から臨んだ斜視図である。前述した第一、第二、第三の実施形態の2極回路遮断器と比較して、電線接続防止手段の構成が異なる。 FIG. 4: is the perspective view which faced from the direction of the load side terminal part of this 2 pole circuit breaker for demonstrating the 2 pole circuit breaker of 4th embodiment of this invention. Compared with the two-pole circuit breaker of the first, second, and third embodiments described above, the configuration of the wire connection preventing means is different.

図4における電線接続防止手段72は、前記電線挿入孔に差し込まれる差し込み部が形成されるとともに、前記検電用孔5を覆うように階段状に形成され、なおかつ前記電線接続表示孔8に嵌め込まれる突起部を設けて構成されるが、第二の実施の形態では2極両方の電線挿入孔に差し込むとともに、2極両方の検電用孔5を覆い、2極両方の電線接続表示孔8に嵌め込まれる突起部を設けて構成されるのに対して、片極の電線挿入孔に差し込み、片極の検電用孔5を覆い、片極の電線接続表示孔8に嵌め込まれる突起部を設けて階段状に構成される。 The wire connection preventing means 72 in FIG. 4 is formed in a stepped shape so as to cover the voltage detection hole 5 while being formed with an insertion portion to be inserted into the wire insertion hole, and is fitted into the wire connection display hole 8.

Provided and configured in a staircase shape.

2極両方に電線接続防止手段を設ける場合と比較して、該電線接続防止手段の材料費が半分程で構成できるため、よりコストを削減することが可能となる。なお、配線の施工時において、作業者はどちらかの極に該電線接続防止手段が設けられている場合には、当該分岐開閉器は予備回路用の分岐開閉器であると認識できるため、電線を予備回路用の分岐開閉器に接続するという電線誤接続の可能性が極力低減する。 Compared with the case where the wire connection preventing means is provided for both of the two poles, the material cost of the wire connection preventing means can be reduced to about half, so that the cost can be further reduced. In addition, at the time of wiring construction, when the wire connection prevention means is provided on either pole, the operator can recognize that the branch switch is a branch switch for a spare circuit. The possibility of erroneous connection of the wires is reduced as much as possible.

図5には、本発明の2極回路遮断器10において、電線接続防止手段73を取外した図を示している。電線接続防止手段73は、前記差し込み部を前記電線挿入孔に差し込み、前記突起部を電線接続表示孔8に嵌め込んで使用するため、取付け及び取外しが行える。 In FIG. 5, the figure which removed the electric wire connection prevention means 73 in the two-pole circuit breaker 10 of this invention is shown. Since the wire connection preventing means 73 is used by inserting the insertion portion into the wire insertion hole and fitting the protrusion into the wire connection display hole 8, the attachment and removal can be performed.

このため、分電盤内に予備回路として設けておいた分岐開閉器を実際に使用する場合においても前記電線接続防止手段を取外すことで容易に配線を行うことが可能である。また、施工時において一時的に電線を接続しない場合においても、改めて電線の接続が必要となった場合には容易に電線を接続することが可能となり作業が効率的に行え、作業工数を低減できるものである。 For this reason, even when the branch switch provided as a spare circuit in the distribution board is actually used, wiring can be easily performed by removing the wire connection preventing means. In addition, even when the wires are not temporarily connected at the time of construction, if the wires need to be connected again, the wires can be easily connected, the work can be performed efficiently, and the work man-hours can be reduced. Is.

以上説明したように,本発明の2極回路遮断器においては、電線の接続を防止する電線接続防止手段を備えたものであるから、例えば、将来的な分岐回路数増に対応させるための予備回路ではなく、分電盤内に配設されている分岐開閉器が故障した場合の取替え用として予め分電盤内に配設しておくための分岐開閉器として用いることができる可能性がある。 As described above, the two-pole circuit breaker according to the present invention is provided with the wire connection preventing means for preventing the connection of the wires. For example, the spare circuit breaker is prepared for the future increase in the number of branch circuits. There is a possibility that it can be used not as a circuit but as a branch switch for preliminarily placing in the distribution board for replacement when the branch switch arranged in the distribution board fails. .

また、JIS C 8370において定義されているように電灯分電盤の分岐回路用の遮断器として用いられる1極型の電灯分電盤用協約形配線用遮断器のように、本発明の2極回路遮断器のうち片側の極の使用を行わず1極の回路遮断器として用いることができる可能性がある。この場合には、実施の形態のうち第三、第四の実施の形態のように、電線接続防止手段を片側の極に適用して一方の負荷側端子部にのみ電線接続が行うことができるように構成し、1極の回路遮断器もしくはニュートラルスイッチとして用いることができる可能性がある。 Further, as defined in JIS C 8370, the two-pole of the present invention is used as a one-pole type electric circuit breaker circuit breaker circuit breaker used as a breaker for a branch circuit of a lamp distribution board. There is a possibility that the circuit breaker can be used as a one-pole circuit breaker without using one pole. In this case, as in the third and fourth embodiments of the embodiments, the wire connection prevention means can be applied to the pole on one side to connect the wire only to one load side terminal portion. Thus, there is a possibility that it can be used as a one-pole circuit breaker or a neutral switch.

即ち、2極回路遮断器が2極2素子で構成される場合には、いずれの極の負荷側端子部に電線接続防止手段を設けても引き外し素子付の1極回路遮断器として利用でき、2極1素子で構成される場合には、素子が設けられている側の負荷側端子部に電線接続防止手段を設けた場合には引き外し素子なしのニュートラルスイッチとして利用でき、素子が設けられていない側の負荷側端子部に電線接続防止手段を設けた場合には引き外し素子付の1極回路遮断器として利用でき、電線接続防止手段を設ける極に応じて2種類の回路遮断器/ニュートラルスイッチとして利用ができるものである。 That is, when the 2-pole circuit breaker is composed of 2 poles and 2 elements, it can be used as a 1-pole circuit breaker with a tripping element, even if a wire connection prevention means is provided at the load side terminal of any pole. When it is composed of 2 poles and 1 element, it can be used as a neutral switch without a tripping element when an electric wire connection prevention means is provided at the load side terminal portion where the element is provided. When a wire connection prevention means is provided at the load side terminal portion that is not provided, it can be used as a one-pole circuit breaker with a tripping element, and there are two types of circuit breakers depending on the pole where the wire connection prevention means is provided / It can be used as a neutral switch.
