Description
【０００１】0001
本考案は、接点開閉時に発生するアークを消弧できる接点開閉機構に関するも のである。 This invention relates to a contact opening/closing mechanism that can extinguish the arc that occurs when the contacts open and close. It is.
【０００２】0002
従来、接点開閉時に発生するアークを消弧する機構として、特公平２─３０１ ２９号公報に開示するように、接点開閉位置近傍に金属消弧板を設けたものがあ る。この金属消弧板は、接点間に発生するアークを引っ張ってアークを伸長する ことにより冷却して消弧するものである。 Conventionally, as a mechanism for extinguishing the arc that occurs when opening and closing contacts, the As disclosed in Publication No. 29, there is one in which a metal arc-extinguishing plate is provided near the contact opening/closing position. Ru. This metal arc-extinguishing plate stretches the arc by pulling the arc that occurs between the contacts. This cools the arc and extinguishes it.
【０００３】0003
しかしながら、前記金属消弧板を用いるものでは、確かに消弧する機構として は優れているが、小型のリレー等のように、取付スペースの少ないものには適さ ない。また、部品点数が多くなり、コストアップの原因となる。 このため、本考案では、少ないスペースで接点開閉時に発生するアークを消弧 できる安価な接点開閉機構を提供することを目的とする。 However, in the case of using the metal arc-extinguishing plate, the mechanism for extinguishing the arc is is excellent, but is not suitable for items with limited installation space, such as small relays. do not have. Furthermore, the number of parts increases, which causes an increase in costs. For this reason, the present invention extinguishes the arc that occurs when opening and closing contacts in a small space. The purpose of this invention is to provide an inexpensive contact opening/closing mechanism.
【０００４】0004
本考案は前記目的を達成するため、接点開閉機構を、対向する接触片の少なく とも一方の縁部に、他方の接触片の接点までの直線距離が、接点開離時の接点間 距離とほぼ等しい放電電極部を一体に設けた構成としたものである。 In order to achieve the above object, the present invention has a contact opening/closing mechanism with fewer opposing contact pieces. The straight line distance between the contacts on one edge of the other contact piece and the contacts when the contacts are opened is The discharge electrode portion is integrally provided with a distance approximately equal to the distance.
【０００５】[0005]
本考案によれば、接点開閉時に発生したアークは、接点間から放電電極部に引 っ張られて消弧されることになる。 According to the present invention, the arc generated when the contacts open and close is pulled from between the contacts to the discharge electrode. The arc will be extinguished due to tension.
【０００６】[0006]
【実施例】 次に、本考案に係る接点開閉機構の実施例について添付図面を参照して説明す る。 図１に示す電磁継電器は、ベース１上に本願接点開閉機構およびその駆動機構 を備えたもので、この駆動機構は、鉄芯２にスプール３を介してコイル４を巻回 した電磁石の励磁，消磁に基づいて、ヨーク５の先端部を支点として略く字形状 の可動鉄片６を回動し、カード７を介して可動接触片１０の背面を押圧して駆動 するものである。なお、８はコイル端子である。【Example】 Next, an example of the contact opening/closing mechanism according to the present invention will be explained with reference to the attached drawings. Ru. The electromagnetic relay shown in FIG. This drive mechanism winds a coil 4 around an iron core 2 via a spool 3. Based on the excitation and demagnetization of the electromagnet that The movable iron piece 6 is rotated and the back side of the movable contact piece 10 is pressed through the card 7 to drive it. It is something to do. Note that 8 is a coil terminal.
【０００７】 一方、前記接点開閉機構は、ベース１上に対向，立設した可動接触片１０およ び固定接触片１２からなり、固定接触片１２の上方側の側端縁部には放電電極部 １４が形成されている。 この放電電極部１４は、図２に示すように、固定接点１３の近傍に位置する固 定接触片１２の側端縁部を、対向する可動接触片１０の可動接点１１に向かって 折り曲げて形成したもので、その先端部は尖端となっている。そして、接点開離 時の可動接点１１からの寸法は接点間距離とほぼ同寸法で、前記放電電極部１４ と可動接点１１との絶縁距離がとれ、かつ、消弧のできる最適な寸法に設定して ある。 これにより、接点開閉時に接点１１，１３間にアークが発生しても、このアー クは前記放電電極部１４に引っ張られ、消弧されることになる。[0007] On the other hand, the contact opening/closing mechanism includes movable contact pieces 10 and and a fixed contact piece 12, and the upper side edge of the fixed contact piece 12 has a discharge electrode portion. 14 is formed. As shown in FIG. 2, this discharge electrode part 14 is a fixed The side edge of the constant contact piece 12 is directed toward the movable contact 11 of the opposing movable contact piece 10. It is formed by bending it, and its tip is pointed. Then, the contact opens The dimension from the movable contact 11 is approximately the same as the distance between the contacts, and the discharge electrode portion 14 and the movable contact 11, and the dimensions are set to be optimal for arc extinguishing. be. As a result, even if an arc occurs between contacts 11 and 13 when opening and closing the contacts, this arc The arc is pulled by the discharge electrode section 14 and extinguished.
【０００８】 図３に示す接点開閉機構では、放電電極部１４が固定接触片１２の固定接点１ ３の両側縁部から延設されている。このように、放電電極部１４を２箇所に設け たものでは、前記１箇所のものに比べてより効率的にアークの消弧を行なうこと ができる。 なお、図４に示すように、前記放電電極部１４は可動接触片１０に設けるよう にしてもよく、また、接触片１０，１２の側縁縁部のみならず、上端縁部等に設 けるようにしても構わない。[0008] In the contact opening/closing mechanism shown in FIG. It extends from both side edges of 3. In this way, the discharge electrode portions 14 are provided at two locations. The arc extinguisher can extinguish the arc more efficiently than the single-point type described above. I can do it. Note that, as shown in FIG. 4, the discharge electrode portion 14 is provided on the movable contact piece 10. In addition, it may be provided not only at the side edges of the contact pieces 10 and 12 but also at the upper edges, etc. It doesn't matter if you let it go.
【０００９】[0009]
【考案の効果】 以上の説明から明らかなように、本考案に係る接点開閉機構によれば、接点間 に発生するアークを接触片に設けた放電電極部で消弧できるようにしたので、場 所をとらず、小型のリレー等の取付スペースの少ないものに最適である。 また、従来のように金属消弧板を必要としないので、部品点数が少なくなり、 安価となる。[Effect of the idea] As is clear from the above explanation, according to the contact opening/closing mechanism according to the present invention, between the contacts The arc generated during the process can be extinguished by the discharge electrode provided on the contact piece. It does not take up much space and is ideal for small relays and other devices that require little installation space. In addition, since there is no need for a metal arc-extinguishing plate like in the past, the number of parts is reduced. It will be cheaper.
