Description

本発明は、電気コネクタに関し、より詳細には、電流が流れている状態で接続または切断された場合にアークを抑制する電気コネクタに関する。   The present invention relates to an electrical connector, and more particularly to an electrical connector that suppresses arcing when connected or disconnected while a current is flowing.

電気コネクタは、一般に、電気負荷がオンとされている間は接続または切断されるべきでない。通電中の電気コネクタにおける離れている接点間の電気アークは、発火および使用者の火傷の危険を生じ、また、そのようなアークは、コネクタの耐用年数を縮める傾向がある。   Electrical connectors generally should not be connected or disconnected while the electrical load is on. Electrical arcs between remote contacts in a live electrical connector create a risk of ignition and user burns, and such arcs tend to shorten the useful life of the connector.

それにも関わらず、誤りを犯す人間の性質上、時として、電気負荷がオンにされているときに誤って電気コネクタが接続または切断されることがある。電気が交流であるときには、アークはあまり問題とならない。なぜなら、交流の正弦波特性が、電気接点の分離中のある点で電圧をゼロにし、アークが自己消滅する傾向があるからである。しかし、電気が直流である場合、電圧は一定でありゼロにはならないから、離れていく接点間の電気アークは、接点が離れていく期間を超えて持続され、使用者の火傷の危険を生じ、またコネクタの耐用年数を縮める。   Nevertheless, due to the nature of humans who make mistakes, sometimes electrical connectors are accidentally connected or disconnected when the electrical load is turned on. When electricity is alternating current, arcing is not a problem. This is because AC sinusoidal characteristics tend to zero the voltage at some point during the separation of the electrical contacts and the arc tends to self-extinguish. However, if the electricity is direct current, the voltage is constant and does not go to zero, so the electric arc between the contacts that are separated will persist beyond the time that the contacts are separated, creating the risk of user burns. , And shorten the service life of the connector.

この課題を解決する１つの手法は、コネクタ内部に別途の１組のより短い接点を用意し、これらのより短い接点が主電気接続後に係合され、主電気接続前に係合解除されるようにコネクタを構成することである。短い接点を介して流れていた電流が流れなくなったことで、主電気回路の内に別途設けられたスイッチングデバイスを動作させるようにすれば、主電気接続の切断前に、このスイッチングデバイスにより、回路内の電流は遮断される。しかし、追加の接点およびスイッチングデバイスの追加は、システムの大きさとコストの両方を増加する。   One approach to solving this problem is to provide a separate set of shorter contacts within the connector so that these shorter contacts are engaged after the main electrical connection and disengaged before the main electrical connection. It is to constitute a connector. If the switching device provided separately in the main electric circuit is operated because the current flowing through the short contact is no longer flowing, this switching device causes the circuit to be disconnected before disconnection of the main electric connection. The current inside is cut off. However, the addition of additional contacts and switching devices increases both the size and cost of the system.

別の手法は、電気接点の一方の先端部を覆い、コネクタの接続あるいは接続解除の際に、接点間の空気を介する直接の経路を遮断する絶縁障壁を含むことである。しかし、この手法では、アークは、絶縁障壁を迂回する間接的な経路を通って依然として生じ得る。   Another approach is to include an insulating barrier that covers one tip of the electrical contacts and blocks the direct path through the air between the contacts when the connector is connected or disconnected. However, with this approach, the arc can still occur through an indirect path that bypasses the insulating barrier.

したがって、追加の接点およびスイッチングデバイスを追加することなく、接続および切断中に離れている接点間での電気アークを抑制する電気コネクタが要請されている。   Therefore, there is a need for an electrical connector that suppresses electrical arcs between contacts that are separated during connection and disconnection without the addition of additional contacts and switching devices.

新規な一対のコネクタは、追加の接続またはスイッチングデバイスを含まずに、コネクタの結合あるいは結合の解除中に、離れている接点間での電気アークを抑制する。本発明の１つの全般的な態様は、電気接点が接続されあるいは切断される間に、離れている接点間でのアークを抑制する絶縁障壁を含む。それにより、本発明の絶縁障壁は、使用者を電気火傷から保護し、コネクタの耐用年数を延ばす。   The novel pair of connectors does not include additional connections or switching devices, and suppresses electrical arcing between remote contacts during connector coupling or decoupling. One general aspect of the present invention includes an insulating barrier that suppresses arcing between remote contacts while the electrical contacts are connected or disconnected. Thereby, the insulation barrier of the present invention protects the user from electrical burns and extends the useful life of the connector.

絶縁障壁は、雄型障壁と雌型障壁の両方を含み、その少なくとも一方が、接点の少なくとも一方を越えて延び、接点の先端部を覆うように構成される。接点が離されるときに雄型障壁と雌型障壁が互いに係合し、それにより、接点間の空気を介する経路をすべて閉じ、アークを抑制する。   The insulating barrier includes both male and female barriers, at least one of which is configured to extend beyond at least one of the contacts and cover the tip of the contact. When the contacts are released, the male and female barriers engage each other, thereby closing all the air path between the contacts and suppressing the arc.

いくつかの実施形態では、離れている接点間でのアークは、さらに、電気接点の少なくとも一方の先端部を、低い導電率を有する金属を用いて構成することによって抑制され、したがって、接点が離される直前に接続の電気抵抗が大幅に増加され、それにより、追加の接続または特別なスイッチング回路を追加することなく、電気アークに利用可能な電流およびエネルギーを低下させる。   In some embodiments, arcing between distant contacts is further suppressed by configuring the tip of at least one of the electrical contacts with a metal having low conductivity, and thus the contacts are separated. The electrical resistance of the connection is greatly increased just prior to being reduced, thereby reducing the current and energy available to the electrical arc without adding additional connections or special switching circuitry.

本発明の別の全般的な態様では、コネクタの少なくとも一方での電気接点の少なくとも一方が、低い抵抗を有する動作区間と高い抵抗を有する遷移区間とを接点内部に形成するように構成された金属組成を有するバイメタル接点であり、遷移区間は、コネクタが結合される、あるいは結合を解除される際に、排他的に、最初にあるいは最後に接続し、動作区間は、コネクタが完全に結合されているときに電流を伝導する。いくつかの実施形態では、遷移区間は、電気接点の先端部に位置される。   In another general aspect of the invention, at least one of the electrical contacts of at least one of the connectors is configured to form an operating section having a low resistance and a transition section having a high resistance within the contact. Bimetal contacts with composition, the transition section is connected first or last exclusively when the connector is coupled or uncoupled, and the operating section is the connector fully coupled Conducts current when In some embodiments, the transition section is located at the tip of the electrical contact.

図１Ａにしめすように、従来技術の典型的な雄型コネクタと雌型コネクタの対は、雄型接点１００と雌型接点１０２を含む。接点の一方（ここでは雌型接点１０２）は、可撓性であり、ばね１１２によって張力を受けており、それにより、コネクタが結合されるとき、接点１０２の成形領域が雄型接点１００の先端部の乗り上がり、雄型接点１００の接続面を押す。絶縁ハウジング１０４、１０６が、雄型接点と雌型接点を取り囲み、環境の危険から接点を遮蔽し、また、使用者が一対のコネクタを取り扱う際にアークが生じた場合に、使用者をいくらかは保護する。図１Ａの従来技術の例では、追加の絶縁構造１０８、１１０が、接点１００、１０２の外面に近い位置に用意されており、接点１００、１０２を支持し、２つの絶縁ハウジング１０４、１０６が結合するように受取りチャネルを提供する。更に、ばね１１２も備えられ、可撓性の雌型接点１０２と固定の雄型電気接点１００との間に押し付ける力を提供する。   As shown in FIG. 1A, a typical male connector and female connector pair of the prior art includes a male contact 100 and a female contact 102. One of the contacts (here, the female contact 102) is flexible and is tensioned by the spring 112 so that when the connector is coupled, the forming area of the contact 102 is the tip of the male contact 100. Step on the part and push the connection surface of the male contact 100. Insulating housings 104, 106 surround the male and female contacts, shield the contacts from environmental hazards, and do some to the user if an arc occurs when the user handles a pair of connectors. Protect. In the prior art example of FIG. 1A, additional insulating structures 108, 110 are provided near the outer surface of the contacts 100, 102 to support the contacts 100, 102 and to couple the two insulating housings 104, 106 together. To provide a receiving channel. In addition, a spring 112 is also provided to provide a pressing force between the flexible female contact 102 and the fixed male electrical contact 100.

図１Ｂは、電圧が依然として印加されている状態で一部切断されている図１Ａの一対のコネクタを示す。２つの接点１００、１０２の先端部は、短い間隙だけ離され、先端部間で、空気を介する電気アーク１１４が生じている。   FIG. 1B shows the pair of connectors of FIG. 1A partially disconnected with the voltage still applied. The tips of the two contact points 100 and 102 are separated by a short gap, and an electric arc 114 is generated between the tips.

図２Ａは、本発明の一実施形態を接点が接続した状態で示す部分断面図である。この実施形態は、図１Ａの従来技術設計と似ているが、絶縁支持構造１０８、１１０が絶縁障壁構造２００、２０２によって置き換えられている点で異なる。雄型絶縁障壁構造２００は、雄型接点１００の先端を越えた位置まで設けられ、雄型接点１００の先端部を覆う。雌型絶縁障壁２０２は、雌型接点１０２の先端を越えた位置まで設けられている。この実施形態では、雌型障壁２０２は、雌型接点の先端部の前方に存在する。同様の実施形態として、雌型障壁２０２が、雌型接点の端部を覆う、またはほぼ覆う形態があり得る。   FIG. 2A is a partial cross-sectional view showing an embodiment of the present invention with contacts connected. This embodiment is similar to the prior art design of FIG. 1A, except that the insulating support structures 108, 110 are replaced by insulating barrier structures 200, 202. The male insulating barrier structure 200 is provided up to a position beyond the tip of the male contact 100 and covers the tip of the male contact 100. The female insulating barrier 202 is provided up to a position beyond the tip of the female contact 102. In this embodiment, the female barrier 202 is in front of the tip of the female contact. In a similar embodiment, the female barrier 202 can be configured to cover or substantially cover the end of the female contact.

図２Ｂは、一部切断構成で示される図２Ａの実施形態の部分断面図である。２つの接点１００、１０２の端部は大きな距離にわたって離されてはいないが、雄型絶縁障壁２００が雌型絶縁障壁２０２の非常に近くにあり、または物理的に接触しており、それにより、接点１００、１０２間での空気を介するアーク経路を実質的にすべて遮断する。いくつかの実施形態は、コネクタが一部切断されるときに雄型絶縁障壁と雌型絶縁障壁を互いに対して押しつけるばねまたは他の張力付与機構を含む。   2B is a partial cross-sectional view of the embodiment of FIG. 2A shown in a partially cut configuration. The ends of the two contacts 100, 102 are not separated by a large distance, but the male insulating barrier 200 is very close to or in physical contact with the female insulating barrier 202, thereby Virtually all arc paths through the air between the contacts 100, 102 are interrupted. Some embodiments include a spring or other tensioning mechanism that presses the male and female insulation barriers against each other when the connector is partially cut.

図３Ａは、部分断面図である図２Ａおよび図２Ｂに示した一対のコネクタの全体を、接続構成で示した上面図である。図３Ｂは、図３Ａのコネクタ全体の側断面図である。図４Ａは、部分断面図である図２Ａおよび図２Ｂに示した一対のコネクタの全体を、一部切断構成で示した上面図である。図４Ｂは、図４Ａのコネクタ全体の側断面図である。   FIG. 3A is a top view showing the whole of the pair of connectors shown in FIGS. 2A and 2B, which are partial sectional views, in a connection configuration. 3B is a cross-sectional side view of the entire connector of FIG. 3A. FIG. 4A is a top view showing the entire pair of connectors shown in FIGS. 2A and 2B, which are partial sectional views, in a partially cut configuration. 4B is a side sectional view of the entire connector of FIG. 4A.

図５Ａおよび図５Ｂを参照すると、いくつかの実施形態では、少なくとも一方の接点１００の先端の高抵抗部５００を、高い電気抵抗を有するニッケルクロムやステンレス鋼などの金属から製造することによって、本発明によるアークの抑制が向上される。図５Ａは、図２Ａと同様の実施形態の部分側断面図であるが、雄型接点１００の先端部５００が高抵抗金属から形成される点が異なる。この図は、接続構成でコネクタを示し、雌型接点１０２は、例えば銅などの低抵抗材の雄型接点１００の部分と物理的に係合している。   Referring to FIGS. 5A and 5B, in some embodiments, the high resistance portion 500 at the tip of at least one contact 100 is made from a metal such as nickel chrome or stainless steel having high electrical resistance, thereby enabling The arc suppression according to the invention is improved. FIG. 5A is a partial side cross-sectional view of an embodiment similar to FIG. 2A, except that the tip 500 of the male contact 100 is formed from a high resistance metal. This figure shows the connector in a connected configuration, wherein the female contact 102 is physically engaged with a portion of the male contact 100 of a low resistance material such as copper.

図５Ｂは、一部切断構成で示される図５Ａの実施形態の断面図であり、雌型接点１０２は、雄型接点１００の高抵抗端部５００と係合されている。この図から分かるように、係合解除中、雌型接点１０２の端部は、雄型接点１００の低抵抗部分から雄型接点１００の高抵抗部分５００に摺動し、次いで雄型絶縁障壁２０２に摺動することで、雌型接点１０２から雄型接点１００の端部５００へのアークが生じにくくなるように電流を阻止する。つまり、低抵抗からほぼ無限の抵抗へ突然遷移するのではなく、切断中に２ステップで回路の抵抗が高められる。   FIG. 5B is a cross-sectional view of the embodiment of FIG. 5A shown in a partially cut configuration, with the female contact 102 engaged with the high resistance end 500 of the male contact 100. As can be seen from this figure, during disengagement, the end of the female contact 102 slides from the low resistance portion of the male contact 100 to the high resistance portion 500 of the male contact 100 and then the male insulation barrier 202. , The current is blocked so that the arc from the female contact 102 to the end 500 of the male contact 100 is less likely to occur. That is, instead of sudden transition from low resistance to almost infinite resistance, the resistance of the circuit is increased in two steps during disconnection.

本発明の別の全般的な態様では、絶縁障壁２００、２０２が省かれ、主に、少なくとも一方の接点１００の先端の高抵抗部５００を、高い電気抵抗を有するニッケルクロムやステンレス鋼などの金属から製造することによって、アークが抑制される。   In another general aspect of the present invention, the insulation barriers 200 and 202 are omitted, and mainly the high resistance portion 500 at the tip of at least one contact 100 is made of a metal such as nickel chrome or stainless steel having high electrical resistance. By producing from, the arc is suppressed.
