本考案は、小型スイツチに関し、特に、可動接
片が固定接片と接触する際に受片を支点としてシ
ーソーすると同時に摺動接触する形式の小型スイ
ツチに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small switch, and more particularly to a small switch in which a movable contact piece seesaws using a receiving piece as a fulcrum when it comes into contact with a fixed contact piece, and at the same time slides into contact.

は更に遅くなり、従つて、上記問題点を助長する
のみならず、接触面の摩耗速度を大きくする欠点
がある。 The main switch contact mechanisms that have been put into practical use include a seesaw mechanism and a slide mechanism. First, the seesaw mechanism has a structure in which the movable contact piece is brought into contact with the fixed contact piece by colliding with it, so it is structurally characterized by the fact that it is easy to generate a large contact pressure. The advantage of using a material that does not easily form a hard oxide is that it allows a switch that can conduct a large current to flow. However, no matter how high the contact pressure can be, if a material such as copper that easily forms a hard oxide is used, the contact resistance will be high due to the hard oxide, and the switch contact may generate heat and burn out. There is. On the other hand, when the slide switching mechanism is in a state where appropriate contact pressure can be obtained, due to sliding contact,
It has the effect of removing oxides from the contact contact surface, thereby maintaining good contact contact. However, the slow movement of the movable contact piece causes the arc to be drawn for a long time, which tends to cause the contact piece to burn out. For example, the switching speed of the switch becomes slower, which not only exacerbates the above problems but also increases the rate of wear of the contact surfaces.

を示す。 Next, the operation of the embodiment of the present invention described above will be explained. When the handle 19 is tilted little by little, the movable contact piece 21 is displaced while sliding little by little on the receiving piece 12, and when the push rod 18 comes almost above the receiving piece 12, the movable contact piece 21 is moved to the position where it is now. It suddenly separates from the fixed contact piece that it had been in contact with until then, and then comes into contact with the fixed contact piece on the opposite side. When the handle 19 is pushed down a little further, the movable contact piece 2
1 further slides on the receiving piece in the opposite direction to the tilting side of the handle and is displaced. At that time, the V-shaped tip 21a of the movable contact piece 21 scrapes off the oxidized film and burnt surface of the contact part caused by the arc generated between the fixed contact pieces 13 when the switch is opened and closed, as shown in FIG. 4b. , has a so-called cleaning effect. That is, the V-shaped tip 21a scrapes off oxides and the like on the contact surface using its defects, and collects the oxides and the like at its defects and causes them to fall to the outside of the fixed contact piece 13. 24 indicates powder such as oxides which are thus dropped.

It is constructed by forming a notch with a width C on both sides, and the notch is connected to the rising part 1 of the receiving piece.
The four lug pieces 23 may be omitted as a structure for sliding on the lug 2a. Furthermore, as an element for regulating the sliding movement of the movable contact piece 12 in the longitudinal direction, in each of the above-described embodiments, the ear piece 23 of the movable contact piece or the notch and the rising portion 12a of the receiving piece are used. Protrusions (not shown) can be provided on both inner surfaces of the main body 11, and the same function can be performed by the protrusions and the ear piece 23 or the notch.
The rising portion 12a can be omitted.
本考案は以上の如く構成されており、本考案に
よれば、可動接片が固定接片と単に接触、摺動す

際に、接片間に発生した酸化物等を効果的に擦り
取り、外部に除去する(セルフクリーニングす
る)。それによつて、接片の接触面は極めて良好
な接触状態を維持できる効果がある。 The present invention is constructed as described above, and according to the present invention, not only the movable contact piece simply contacts and slides on the fixed contact piece, but also the tip portion of the movable contact piece having a special structure according to the present invention, When sliding on the fixed contact piece, oxides generated between the contact pieces are effectively scraped off and removed to the outside (self-cleaning). This has the effect that the contact surfaces of the contact pieces can maintain extremely good contact conditions.
従つて、従来においては3〜5A、125V程度の
スイツチでも、上下の接点に銀材を用いなければ
ならなかつたのが、本考案に係る構造によれば、
その必要がなくなり、高価な銀材を用いることな

記と同様の容量及び特性を備えたスイツチを容易
に得ることが可能である。また、例えば10A程度
のスイツチの場合には、一方の接片のみに銀材を
用いれば良く、容量の比較的大きいスイツチにお
いても省銀効果が大である。 Therefore, in the past, even switches of 3 to 5 A and 125 V had to use silver material for the upper and lower contacts, but with the structure of the present invention,
This is no longer necessary, and by using, for example, an inexpensive copper material instead of an expensive silver material, it is possible to easily obtain a switch with the same capacity and characteristics as described above. Further, for example, in the case of a switch of about 10 A, it is sufficient to use silver material for only one contact piece, and the silver saving effect is large even in a switch with a relatively large capacity.
また、可動接片の先端部をV字又はU字状の欠
所とする実施例の場合には、いわゆるツインコン
タクトという特徴も現われ、その接触特性は更に
良好のものとなる効果がある。 In addition, in the case of an embodiment in which the tip of the movable contact piece is a V-shaped or U-shaped recess, a so-called twin contact feature also appears, and the contact characteristics are further improved.
更にまた、可動接片は受片及び固定接片の表面
上でスライドするが、従来の直線的な摺動接触と
異なり、可動接片が傾斜しての摺動のために、た
とえ押棒のばねを強くしても、摺動による作動の
重さは軽減される。 Furthermore, the movable contact piece slides on the surfaces of the receiving piece and the fixed contact piece, but unlike the conventional linear sliding contact, the movable contact piece slides at an angle, even if the spring of the push rod Even if it is made stronger, the weight of the sliding action is reduced.
また、本考案においては、第2図に見られる如

ことができる。従つて、上記接点間の耐電圧が大
きくなり、その点において電気的に安全性の高い
スイツチを得ることができ、特に、最近のよう
に、極端に小型化されたスイツチの場合にその効
果は大きなものとなる。 In addition, in the present invention, as shown in FIG. 2, since the dimensional relationship between the length A of the movable contact piece 21 and the distance B between the fixed contact piece 13 is B>A, the movable contact piece is "off". ” side, the inclination angle of the movable contact piece is
Even if the distance is the same as in the conventional case, the distance between the "off" side movable contact piece and the fixed contact piece can be increased. Therefore, the withstand voltage between the contacts is increased, and in this respect, it is possible to obtain a switch with high electrical safety.This effect is particularly noticeable in the case of extremely miniaturized switches as seen recently. It becomes something big.
更にまた、本考案においては、可動接片が左右

つことができる。尚、この原理からも可動接片側
には銀材を用いなくとも良好な接触を保つことが
できる原因の一つが理解される。 Furthermore, in the present invention, since the movable contact piece slides left and right, the position where the movable contact piece makes complete contact with the fixed contact piece is different from the position of the movable contact piece that generates an arc during opening and closing, which further stabilizes the contact resistance. can maintain its condition. This principle also explains one of the reasons why good contact can be maintained without using silver material on the movable contact side.
尚、本考案は図示実施例のスイツチのみなら
ず、レバースイツチ、その他の形式のスイツチに
も同様に適用し得ることは勿論である。 It goes without saying that the present invention can be applied not only to the switch shown in the illustrated embodiment, but also to lever switches and other types of switches.
