【０００１】[0001]
本考案は、各種電子機器で比較的大電流の開閉を行うスイッチに関するもので ある。 The present invention relates to a switch that opens and closes a relatively large current in various electronic devices.
【０００２】[0002]
図６により従来のスイッチについて説明する。同図によると、 １は絶縁材か らなる端子板であり、平板状の共通端子２および共通端子２に平行に第１個別端 子３、および第２個別端子４が配設されている。５はコ字状に形成された可動接 触片であり摺動体７の凹部７ｂに係合されるとともに摺動体７の穴７ａに挿入さ れた圧縮バネ６に付勢されて前記端子群に当接している。８はケースであり、摺 動体７および可動接触片５が摺動可能に収納され、端子板１に固定されている。 A conventional switch will be described with reference to FIG. As shown in the figure, 1 is a terminal plate made of an insulating material, and a flat common terminal 2 and a first individual terminal 3 and a second individual terminal 4 are arranged in parallel to the common terminal 2. Reference numeral 5 denotes a movable contact piece formed in a U-shape, which is engaged with the concave portion 7b of the sliding body 7 and is urged by the compression spring 6 inserted into the hole 7a of the sliding body 7 to cause the terminal group to move. Abutting. Reference numeral 8 denotes a case, in which the sliding body 7 and the movable contact piece 5 are slidably accommodated and fixed to the terminal board 1.
【０００３】 以上のように構成されたスイッチの動作について図７（ａ），（ｂ）を用いて 説明する。まず摺動体７がＡ位置では、可動接触片５は共通端子２および第１個 別端子３に当接し導通している。次に摺動体７の操作部７ｃを動作させＢ位置に 移動すると、可動接触片５は共通端子２および第１個別端子３、第２個別端子４ 両方にまたがって当接し導通する。続いて摺動体７をＣ位置に移動させると、可 動接触片５は共通端子２および第２個別端子３に当接し導通することとなる。摺 動体７を逆方向にＢ，Ａ位置へ移動させると、前記と同様な過程を経て開閉動作 を行う。The operation of the switch configured as above will be described with reference to FIGS. 7A and 7B. First, when the sliding body 7 is at the position A, the movable contact piece 5 is in contact with the common terminal 2 and the first individual terminal 3 to be in conduction. Next, when the operating portion 7c of the sliding body 7 is operated to move to the B position, the movable contact piece 5 contacts both the common terminal 2 and the first individual terminal 3 and the second individual terminal 4 to conduct. Then, when the sliding body 7 is moved to the C position, the movable contact piece 5 comes into contact with the common terminal 2 and the second individual terminal 3 and becomes conductive. When the sliding body 7 is moved in the opposite direction to the B and A positions, the opening / closing operation is performed through the same process as described above.
【０００４】[0004]
しかしながら上記従来の構成では、可動接触片５が第１個別端子３または第２ 個別端子４に閉接または開離する際に、可動接触片５と個別端子間で開閉回数が 増すにつれてアークが発生し、損傷、消耗や消耗粉の付着が生じ、可動接触片５ と各個別端子３，４間の接触不安定が生じ易いこと、および可動接触片５の底面 ５ａは平面状なために可動接触片５が個別端子３，４両方に当接する位置Ｂでは 各端子間の高さのばらつきや各端子の接触面の仕上がりにより可動接触片５の底 面５ａと各個別端子３，４との間に間隙が生じ、接触不能になり易いという問題 点を有していた。 However, in the above conventional configuration, when the movable contact piece 5 closes or separates from the first individual terminal 3 or the second individual terminal 4, an arc is generated as the number of times of opening and closing increases between the movable contact piece 5 and the individual terminal. However, damage, consumption, and attachment of consumable powder easily occur, and contact instability between the movable contact piece 5 and each of the individual terminals 3 and 4 is likely to occur, and the bottom surface 5a of the movable contact piece 5 is a flat surface. At the position B where the piece 5 abuts on both the individual terminals 3 and 4, there is a gap between the bottom surface 5a of the movable contact piece 5 and the individual terminals 3 and 4 due to height variation between the terminals and finish of the contact surface of each terminal. There is a problem in that a gap is created in the area and it becomes difficult to contact them.
【０００５】 本考案は上記従来の問題点を解決するもので、負荷の開閉において接触安定性 に優れ、信頼性の高いスイッチを提供することを目的とする。The present invention solves the above conventional problems, and an object of the present invention is to provide a switch having excellent contact stability and high reliability in opening and closing a load.
【０００６】[0006]
この目的を達成するために本考案のスイッチでは、可動接触片は、共通端子に 相対して凸状の接点部を、個別端子に相対して、可動接触片の動作方向と斜方向 に凸状接点部を設けたものである。 In order to achieve this object, in the switch of the present invention, the movable contact piece has a convex contact portion facing the common terminal and a convex contact portion facing the individual terminal in the operation direction and the oblique direction of the movable contact piece. A contact portion is provided.
【０００７】[0007]
上記構成によって、可動接触片が個別端子に閉接または開離する際に、斜方向 で直線上の凸状接点部の外側よりアークが発生し損傷や消耗を効率的に順次受け 、損傷や消耗を受けない清浄な接点部が確保されているため接触安定性が得られ るものである。 With the above configuration, when the movable contact piece closes or separates from the individual terminal, an arc is generated from the outside of the linear convex contact part in the oblique direction, and the damage and wear are efficiently and sequentially received. The contact stability is obtained because a clean contact that does not receive contact is secured.
【０００８】[0008]
以下本考案のスイッチの一実施例について、図１，図２，図４により説明する 。同図によると、１１は絶縁材からなる端子板であり、平板状の共通端子１２お よび共通端子１２に平行に第１個別端子１３、および第２個別端子１４が配設さ れている。１５はコ字状に形成された可動接触片であり、摺動体１７の凹部１７ ｂに係合されるとともに摺動体１７の穴１７ａに挿入された圧縮バネ１６に付勢 されて前記端子１２〜１４に当接している。可動接触片１５の底面１５ａには共 通端子１２に相対して凸状の接点部１５ｂと、第１，第２の個別端子１３，１４ に各々相対して、可動接触片１５の動作方向と斜方向でかつ凸状接点部１５ｂを 頂点としたＶ字状を形成するように凸状の接点部１５ｃ，１５ｄが形成されてい る。１８はケースであり、摺動体１７および可動接触片１５が摺動可能に収納さ れ、端子板１１に固定されている。 An embodiment of the switch of the present invention will be described below with reference to FIGS. As shown in the figure, 11 is a terminal plate made of an insulating material, and a common terminal 12 having a flat plate shape and a first individual terminal 13 and a second individual terminal 14 are arranged in parallel to the common terminal 12. Reference numeral 15 denotes a movable contact piece formed in a U-shape, which is engaged with the concave portion 17b of the sliding body 17 and is biased by the compression spring 16 inserted into the hole 17a of the sliding body 17 to urge the terminals 12 ... It is in contact with 14. On the bottom surface 15a of the movable contact piece 15, a convex contact portion 15b facing the common terminal 12 and on the operating direction of the movable contact piece 15 facing the first and second individual terminals 13 and 14, respectively. Convex contact portions 15c and 15d are formed so as to form a V-shape in an oblique direction with the convex contact portion 15b as the apex. Reference numeral 18 denotes a case, in which the sliding body 17 and the movable contact piece 15 are slidably accommodated and fixed to the terminal board 11.
【０００９】 以上のように構成されたスイッチについて、以下その動作について図４，図５ （ａ）〜（ｈ）により説明すると、まず摺動体１７がＡ位置（図５（ａ）および （ｅ）の位置）では、可動接触片１５は共通端子１２および第１個別端子１３に 当接し導通している。次に摺動体１７の操作部１７ｃを動作させ可動接触片１５ の凸状接点部１５ｄが第２個別端子１４に接する際（図５（ｂ）および（ｆ）の 位置）には、この凸状接点部１５ｄの外側端部においてアークを発生しながら、 第２個別端子１４に当接する。さらに摺動体１７がＢ位置（図５（ｃ）および（ ｇ）の位置）に移動すると、可動接触片１５は凸状接点部１５ｂを頂点として凸 状接点部１５ｃ，１５ｄを２辺とするＶ字形のごとく共通端子１２および第１， 第２個別端子１３，１４両方にまたがって当接し導通する。続いて摺動体１７が Ｃ位置（図５（ｄ）および（ｈ）の位置）に移動すると、可動接触片１５は共通 端子１２および第２個別端子１４に当接し導通することとなる。摺動体１７を逆 方向にＢ，Ａ位置へ移動させると、前記と同様な過程を経て動作を行う。The operation of the switch configured as described above will be described below with reference to FIGS. 4 and 5 (a) to 5 (h). First, the sliding body 17 is in the A position (FIGS. 5 (a) and 5 (e)). In the position (1), the movable contact piece 15 is in contact with the common terminal 12 and the first individual terminal 13 to be in conduction. Next, when the operating portion 17c of the sliding body 17 is operated and the convex contact portion 15d of the movable contact piece 15 contacts the second individual terminal 14 (positions in FIGS. 5B and 5F), While contacting the second individual terminal 14, an arc is generated at the outer end of the contact portion 15d. When the sliding body 17 is further moved to the B position (positions (c) and (g) in FIG. 5), the movable contact piece 15 has a convex contact portion 15b as the apex and the convex contact portions 15c and 15d as two sides V. As in the shape of a letter, the common terminal 12 and the first and second individual terminals 13 and 14 are contacted and conducted to each other. Then, when the sliding body 17 moves to the C position (positions in FIGS. 5D and 5H), the movable contact piece 15 comes into contact with the common terminal 12 and the second individual terminal 14 and becomes conductive. When the sliding body 17 is moved in the opposite direction to the B and A positions, the operation is performed through the same process as described above.
【００１０】 以上のように可動接触片１５の凸状接点部１５ｄ，１５ｃは動作方向に対して 斜め方向の凸部として設けられているのでアークは外側端部から発生し、損傷や 消耗を順次受けるので清浄な接点部が確保され、接触安定性を確保するものであ る。As described above, since the convex contact portions 15d and 15c of the movable contact piece 15 are provided as the convex portions in the oblique direction with respect to the operation direction, the arc is generated from the outer end portion, and damage and wear are sequentially caused. Since the contact is received, a clean contact part is secured and contact stability is secured.
【００１１】 なお、図３は可動接触片の他の実施例の要部を示すもので、共通端子に相対す る凸状接点部２１ｂと個別端子に相対する凸状接点部２１ｃ，２１ｄとを一体に 形成したものである。また、上記実施例においては、スライド操作形スイッチと したが、プッシュ操作形でもよいことは言うまでもない。FIG. 3 shows a main part of another embodiment of the movable contact piece, which has a convex contact portion 21b facing the common terminal and convex contact portions 21c and 21d facing the individual terminals. It is formed integrally. Further, in the above embodiment, the slide operation type switch is used, but it goes without saying that the push operation type switch may be used.
【００１２】[0012]
以上のように本考案は、可動接触片に共通端子に相対して凸状の接点部を、個 別端子に相対して可動接触片の動作方向と斜方向の凸状の接点部を形成すること により、可動接触片が個別端子に閉接または開離する際に、斜方向で直線上の凸 状接点部の外側よりアークが発生し損傷や消耗を順次受け、損傷や消耗を受けな い清浄な接点部を確保して接触安定性を得るものである。 As described above, according to the present invention, the movable contact piece is formed with the convex contact portion facing the common terminal, and the movable contact piece is formed with the convex contact portion facing the operation direction of the movable contact piece and the oblique direction. As a result, when the movable contact piece closes or separates from the individual terminal, an arc is generated from the outside of the linear convex contact part in the oblique direction, and the damage and wear are sequentially received. The contact point is secured by ensuring a clean contact point.
【００１３】 なお、個別端子を２個設けた場合、可動接触片は共通端子に相対する凸状接点 部を頂点として、各個別端子に相対する凸状接点部は、略Ｖ字形に形成した場合 、常に可動接触片は共通端子および第１，第２の個別端子に安定して当接される という効果を有するものであり、本考案は簡易な構造により、接触安定性に優れ 、信頼性の高いスイッチを実現するものである。When two individual terminals are provided, the movable contact piece has a convex contact portion facing the common terminal as an apex, and the convex contact portion facing each individual terminal is formed in a substantially V shape. Since the movable contact piece is always brought into stable contact with the common terminal and the first and second individual terminals, the present invention has a simple structure and is excellent in contact stability and reliable. It realizes a high switch.
