Description

本発明は、活線と中性線の電力が温度上昇時に同時に切断されるよう確約する電路の保護構造、及び、この保護構造を利用したプラグあるいはコンセントに関する。   The present invention relates to a protection structure for an electric circuit that ensures that the power of a live wire and a neutral wire is cut simultaneously when the temperature rises, and a plug or an outlet using the protection structure.

電路に電流過負荷、短絡、過熱等の状況が発生することを防ぐため、通常は電路上にヒューズやブレーカーが設置され、電路の温度が高すぎる、または電流が大きすぎるとき、ヒューズが高温の影響を受けて溶断される、あるいはブレーカーの金属弾性片がトリップして、電路を開成して電流を切断し、電力使用時の安全を保障している。   In order to prevent the occurrence of current overload, short circuit, overheating, etc. in the circuit, fuses and breakers are usually installed on the circuit, and when the temperature of the circuit is too high or the current is too high, the fuse It is melted under the influence, or the metal elastic piece of the breaker trips, opens the electric circuit, cuts the current, and ensures the safety when using the power.

特許文献1に記載の「絶縁式昇温破壊固定片及び前記絶縁式昇温破壊固定片を使用したプラグ、コンセント」は、絶縁式昇温破壊固定片が連接部材と、前記連接部材の二端に結合された2つの規制部材を含んで、H字形の構造となっており、前記連接部材が導電片上に形成された溝部内に設置され、前記2つの規制部材を前記2つの導電部材の相対する外側に当接させ、前記2つの導電部材を相互に接触させて位置規制し、前記連接部材が過熱時に破壊されて、前記2つの導電部材間に切断状態が形成されるものである。   The “insulation-type temperature rising fracture fixing piece and the plug and outlet using the insulation-type temperature rising destruction fixing piece” described in Patent Document 1 are an insulating type temperature rising destruction fixing piece having a connecting member and two ends of the connecting member. The connecting member is installed in a groove formed on the conductive piece, and the two restricting members are positioned relative to the two conductive members. The two conductive members are brought into contact with each other and regulated in position, and the connecting member is broken when overheated, and a cut state is formed between the two conductive members.

上記特許文献1に記載のものは、各活線弾性片と活線導電片には昇温破壊固定片が使用されており、各中性線弾性片と中性線導電片には別の昇温破壊固定片が使用されている(上記特許文献1の図21参照)。そして、負荷(電器)が活線導電片と中性線導電片の間に接続されると、電流が活線弾性片、活線導電片、負荷(電器)、中性線導電片と中性線弾性片を順に経由して電流通路が形成される。
従って、過熱した位置が中性線弾性片と中性線導電片の間の場合、中性線弾性片と中性線導電片の間の固定片が温度上昇によって破壊されるが、このとき、活線弾性片と活線導電片の間に位置する固定片が破壊されず、電流の切断状態が形成される前の高電流が負荷に入ってしまい、前記負荷が漏電していると、操作者が接地状態下で前記負荷に触れたとき、操作者が感電してしまう可能性がある。
In the above-described Patent Document 1, a temperature rising fracture fixing piece is used for each of the live wire elastic pieces and the live wire conductive pieces, and each of the neutral wire elastic pieces and the neutral wire conductive pieces is provided with a separate riser. A thermal fracture fixing piece is used (see FIG. 21 of Patent Document 1). And if a load (electric appliance) is connected between a hot wire conductive piece and a neutral wire conductive piece, an electric current is a hot wire elastic piece, a hot wire conductive piece, a load (electric appliance), a neutral wire conductive piece, and neutral. A current path is formed through the wire elastic pieces in order.
Therefore, when the overheated position is between the neutral wire elastic piece and the neutral wire conductive piece, the fixing piece between the neutral wire elastic piece and the neutral wire conductive piece is destroyed by the temperature rise, If the fixed piece located between the hot-wire elastic piece and the hot-wire conductive piece is not broken, the high current before the current cut state is formed enters the load, and the load is leaked, When an operator touches the load in a grounded state, the operator may get an electric shock.

また、特許文献2に記載のものは、活線導電片(live wire conductive plate)と活線接触部(live wire contact portion)間に個別に独立した位置規制部材(limiting element)が使用され、中性線導電片(neutral wire conductive plate)と中性線接触部(neutral wire contact portion)間も個別に独立した別の位置規制部材(limiting element)が使用されている。 このため、特許文献2に記載の構造にも、特許文献1に開示されたプラグ、コンセントと同様の問題が存在する。即ち、過熱状況下で、中性線導電片と中性線接触部の間の位置規制部材のみが破壊され、活線導電片と活線接触部の間の位置規制部材が完全に維持される可能性がある。   In addition, the device described in Patent Document 2 uses an independent positioning element between a live wire conductive plate and a live wire contact portion. Another independent positioning element is also used between the neutral wire conductive plate and the neutral wire contact portion. For this reason, the structure described in Patent Document 2 has the same problem as the plug and outlet disclosed in Patent Document 1. That is, only the position regulating member between the neutral wire conductive piece and the neutral wire contact portion is destroyed under an overheating condition, and the position regulating member between the live wire conductive piece and the live wire contact portion is completely maintained. there is a possibility.

The thickness T of the fractured portion 4 is smaller than the thickness T ′ of the connecting member 3.

図3及び図4に示すように、活線と中性線はやや間隔をあけて並べて配置される。
活線は、活線弾性片5及び活線導電片6から成り、活線弾性片5と活線導電片6が互いに接触した時電流が流れるようになっている。なお、活線弾性片5は、活線導電片6の外側に配置され、活線導電片6から離間するよう付勢されている。
また、中性線は、中性線弾性片7及び中性線導電片8から成り、中性線弾性片7と中性線導電片8が互いに接触した時電流が流れるようになっている。なお、中性線弾性片7は中性線導電片8の外側に配置され、中性線導電片8から離間するよう付勢されている。
As shown in FIGS. 3 and 4, the live line and the neutral line are arranged side by side with a slight gap therebetween.
The hot wire is composed of a hot-wire elastic piece 5 and a hot-wire conductive piece 6, and a current flows when the hot-wire elastic piece 5 and the hot-wire conductive piece 6 come into contact with each other. The hot wire elastic piece 5 is disposed outside the live wire conductive piece 6 and is urged so as to be separated from the live wire conductive piece 6.
Further, the neutral wire is composed of the neutral wire elastic piece 7 and the neutral wire conductive piece 8, and a current flows when the neutral wire elastic piece 7 and the neutral wire conductive piece 8 come into contact with each other. The neutral wire elastic piece 7 is disposed outside the neutral wire conductive piece 8 and is urged to be separated from the neutral wire conductive piece 8.

保護部材10は、活線弾性片5と活線導電片6を相互に接触させて位置規制するため、及び、中性線弾性片7と中性線導電片8を相互に接触させて位置規制するために用いられる。
活線導電片6には第1凹部61が形成され、活線弾性片5に第2凹部51が形成され、中性線導電片8に第3凹部81が形成され、中性線弾性片7に第4凹部71が形成される。本実施例において、第1凹部61の幅Wは第2凹部51の幅W’より大きく、第3凹部81の幅Wは第4凹部71の幅W’より大きい。
The protection member 10 places the live-line elastic piece 5 and the live-line conductive piece 6 in contact with each other and regulates the position, and the neutral-line elastic piece 7 and the neutral-wire conductive piece 8 come in contact with each other to regulate the position. Used to do.
A first concave portion 61 is formed in the live wire conductive piece 6, a second concave portion 51 is formed in the live wire elastic piece 5, a third concave portion 81 is formed in the neutral wire conductive piece 8, and the neutral wire elastic piece 7. The 4th recessed part 71 is formed in this. In this embodiment, the width W of the first recess 61 is greater than the width W ′ of the second recess 51, and the width W of the third recess 81 is greater than the width W ′ of the fourth recess 71.

保護部材10で活線弾性片5と活線導電片6、及び、中性線弾性片7と中性線導電片8を互いに接触した位置で位置規制するには、まず、力Fを加えて活線弾性片5を活線導電片6に当接させると共に、中性線弾性片7を中性線導電片8に当接させた後、第1規制部材1及び第2規制部材2を活線弾性片5と中性線弾性片7の外側面にそれぞれ当接させ、かつ連接部材3を第1凹部61、第2凹部51、第3凹部81、第4凹部71に収容することで、活線弾性片5と中性線弾性片7を位置規制し、活線弾性片5と活線導電片6を相互に接触させ、且つ、中性線弾性片7と中性線導電片8を相互に接触させる。
第1凹部61の幅Wが第2凹部51の幅W’より大きく、第3凹部81の幅Wが第4凹部71の幅W’より大きいのは、第1凹部61及び第3凹部81に充分な空間を提供し、破壊された後の連接部材3の動きを妨げないようにするためである。
In order to control the position of the live elastic piece 5 and the live conductive piece 6 and the neutral elastic piece 7 and the neutral conductive piece 8 at the position where they are in contact with each other with the protective member 10, first, a force F is applied. The hot wire elastic piece 5 is brought into contact with the live wire conductive piece 6 and the neutral wire elastic piece 7 is brought into contact with the neutral wire conductive piece 8, and then the first restricting member 1 and the second restricting member 2 are activated. By bringing the connecting member 3 into contact with the outer surfaces of the linear elastic piece 5 and the neutral linear elastic piece 7 and accommodating the connecting member 3 in the first concave portion 61, the second concave portion 51, the third concave portion 81, and the fourth concave portion 71, The positions of the hot wire elastic piece 5 and the neutral wire elastic piece 7 are regulated, the hot wire elastic piece 5 and the hot wire conductive piece 6 are brought into contact with each other, and the neutral wire elastic piece 7 and the neutral wire conductive piece 8 are Contact each other.
The reason why the width W of the first recess 61 is larger than the width W ′ of the second recess 51 and the width W of the third recess 81 is larger than the width W ′ of the fourth recess 71 is the first recess 61 and the third recess 81. This is to provide a sufficient space so as not to hinder the movement of the connecting member 3 after being destroyed.

破壊された後の連接部材3の動きを妨げないようにするために、活線導電片6と中性線導電片8はその他形態で実施してもよい。
例えば、図3Aに示すように、活線弾性片5Aと活線導電片6Aを相互に接触させて位置規制し、且つ、中性線弾性片7Aと中性線導電片8Aを相互に接触させて位置規制するとともに、活線弾性片5Aに第1凹部51Aが形成され、中性線弾性片7Aに第2凹部71Aが形成され、活線導電片6Aと中性線導電片8Aの延伸長さが第1凹部51A及び第2凹部71Aを超えないようにする。
In order not to prevent the movement of the connecting member 3 after being destroyed, the live wire conductive piece 6 and the neutral wire conductive piece 8 may be implemented in other forms.
For example, as shown in FIG. 3A, the hot-wire elastic piece 5A and the hot-wire conductive piece 6A are brought into contact with each other to regulate the position, and the neutral-wire elastic piece 7A and the neutral wire conductive piece 8A are brought into contact with each other. The first concave portion 51A is formed in the hot wire elastic piece 5A, the second concave portion 71A is formed in the neutral wire elastic piece 7A, and the extension length of the live wire conductive piece 6A and the neutral wire conductive piece 8A Does not exceed the first recess 51A and the second recess 71A.

図3と図5に示すように、活線弾性片5と活線導電片6の間が過熱したとき、または中性線弾性片7と中性線導電片8の間が過熱したときは、第1規制部材1、第2規制部材2、連接部材3の内のどの箇所が破壊されても、第1規制部材1、第2規制部材2と連接部材3が位置規制作用を失い、活線弾性片5と活線導電片6 、中性線弾性片7と中性線導電片8が同時に分離される。
例えば本実施例において、過熱時、通常は被破壊部4から破壊が発生する。第1凹部61の幅Wと第3凹部81の幅Wがいずれも比較的大きいため、破壊された後の連接部材3は充分な活動空間を有し、活線弾性片5と活線導電片6、中性線弾性片7と中性線導電片8の同時分離が確約される。
As shown in FIGS. 3 and 5, when the space between the hot wire elastic piece 5 and the live wire conductive piece 6 is overheated, or when the space between the neutral wire elastic piece 7 and the neutral wire conductive piece 8 is overheated, Regardless of which part of the first restricting member 1, the second restricting member 2, and the connecting member 3 is destroyed, the first restricting member 1, the second restricting member 2, and the connecting member 3 lose the position restricting action, and the live line The elastic piece 5 and the live wire conductive piece 6, the neutral wire elastic piece 7 and the neutral wire conductive piece 8 are separated simultaneously.
For example, in this embodiment, destruction usually occurs from the part to be destroyed 4 during overheating. Since both the width W of the first recess 61 and the width W of the third recess 81 are relatively large, the connecting member 3 after being destroyed has a sufficient active space, and the hot-wire elastic piece 5 and the hot-wire conductive piece. 6. The simultaneous separation of the neutral wire elastic piece 7 and the neutral wire conductive piece 8 is ensured.
