本発明のスイッチ装置の固定接点には、外部に配設している外部接続部材に接続可能な接続部が形成され、固定接点は、ケース内部に収納したウエハに支持され、このウエハの端面から所定長さで延出する延出基部を有し、この延出基部の延出端部に形成した接続部が外部接続部材に接続可能になっており、
外部接続部材を接続部に接続するときに加わる荷重によって、延出基部が変形するのを防止するための補強壁を前記ケースまたは前記ウエハに形成したので、外部接続部材に固定接点の接続部を接続するときに補強壁によって延出基部が補強されて変形を確実に防止できる。
また、固定接点には、延出基部の端面から延出する延出端部を端面に沿って折り返して折り返し根元部が形成され、この折り返し根元部に当接、または近接させて補強壁が形成されているので、更に確実に固定接点に延出基部の変形を防止できる。 The fixed contact of the switch device of the present invention is formed with a connection portion that can be connected to an external connection member disposed outside, and the fixed contact is supported by a wafer housed inside the case, and from the end surface of the wafer. It has an extension base that extends at a predetermined length, and the connection part formed at the extension end of this extension base is connectable to an external connection member,
Since the reinforcing wall for preventing the extension base portion from being deformed by the load applied when the external connection member is connected to the connection portion is formed on the case or the wafer, the connection portion of the fixed contact is formed on the external connection member. When connecting, the extending base is reinforced by the reinforcing wall, so that deformation can be reliably prevented.
In addition, the fixed contact has an extended end portion extending from the end surface of the extended base portion folded back along the end surface to form a folded root portion, and a reinforcing wall is formed in contact with or close to the folded root portion. Therefore, the deformation of the base extending to the fixed contact can be prevented more reliably.

また、補強壁は、ケース内面から突出させて折り返し根元部に当接したので、ケースを成形加工するときに一体形成でき加工性に優れている。
また、接続部は、端面に沿ってＵ字状に折り返し形成されて開放部と折り返し基部とが形成され、折り返し基部には、この折り返し基部を所定の幅寸法で切り欠きして外部接続部材が挿通可能な差込孔が形成され、
補強壁は、折り返し根元に当接し、差込孔側から外部接続部材を挿通したときに延出基部が変形するのを防止するようにしたので、延出基部が変形するのを防止して、固定接点の接続部と外部接続部材との接続を確実にすることができる。
また、接続部のＵ字状の折り返し基部は、挿通孔を挟んで互いに対向する連結部が形成され、外部接続部材を開放部側から差し込むと、連結部がケース内面に当接して、延出基部の変形が防止されるので、Ｕ字状の開放部側から外部接続部材を挿入しても、延出基部が変形するのを防止できる。
そのために、補強壁は、ケース内面の一方側だけに形成すれば良くケースの加工性が良い。 Further, since the reinforcing wall protrudes from the inner surface of the case and comes into contact with the folded root portion, it can be integrally formed when the case is molded and has excellent workability.
The connecting portion is formed in a U shape along the end surface to form an open portion and a folded base portion. The folded base portion is cut out with a predetermined width dimension so that an external connection member is formed. Insertable insertion holes are formed,
Since the reinforcing wall is in contact with the folded root and prevents the extended base from being deformed when the external connection member is inserted from the insertion hole side, the extended base is prevented from being deformed, The connection between the fixed contact and the external connection member can be ensured.
In addition, the U-shaped folded base portion of the connecting portion is formed with a connecting portion facing each other across the insertion hole. When the external connecting member is inserted from the open portion side, the connecting portion abuts on the inner surface of the case and extends. Since the deformation of the base is prevented, it is possible to prevent the extension base from being deformed even when the external connection member is inserted from the U-shaped opening.
For this reason, the reinforcing wall only needs to be formed on one side of the inner surface of the case, and the workability of the case is good.

The first contact portion 4a is formed with an extension height higher than that of the second contact portion 6a.
Therefore, a movable contact 9 described later is always in contact with the first contact portion 4a higher than the second contact portion 6a. However, the lever member 2 is rotated to the second contact portion 5a having a low height. The movable contact 9 can be contacted and separated by being moved.

またＵ字状の第１接続部５は、図４、図５に示すように、一方側が開放されて開放部５ａが形成され、他方側の折り返し基部５ｂが延出基部４ｂと略同じ幅寸法でＵ状になっている。
前記他方側の折り返し基部５ｂを所定の幅寸法（寸法Ｂ）で切り欠きして差込孔５ｃが形成され、この差込孔５ｃ近傍、および開放部５ａ近傍には、互いに対向する内向きに三角状に折り曲げられて、片持ち状の第１、第２弾接部５ｄ、５ｅが形成されている。 As shown in FIGS. 4 and 5, the U-shaped first connecting portion 5 is open on one side to form an open portion 5a, and the folded base portion 5b on the other side is substantially the same width dimension as the extended base portion 4b. It is U-shaped.
The folded base 5b on the other side is cut out with a predetermined width dimension (dimension B) to form an insertion hole 5c. In the vicinity of the insertion hole 5c and in the vicinity of the open part 5a, inwardly facing each other. The cantilevered first and second elastic contact portions 5d and 5e are formed by being bent in a triangular shape.

前記差込孔５ｃの幅寸法（寸法Ｂ）は、第１挿通孔１ｇの幅寸法と略同じか、第１挿通孔１ｇより若干大きく形成されている。
このことにより、後述する外部接続部材１０が、開放部５ａ側、あるいは差込孔５ｃ側のどちらから挿入されたとしても、外部接続部材１０が無理なく第１、第２弾接部５ｄ、５ｅに到達して、第１、第２弾接部５ｄ、５ｅが拡がる方向に弾性変形するようになっている。
そのために、第１、第２固定接点４、６と外部接続部材１０とが、電気的に確実に接続されるようになっている。 The width dimension (dimension B) of the insertion hole 5c is substantially the same as the width dimension of the first insertion hole 1g or slightly larger than the first insertion hole 1g.
As a result, even if an external connection member 10 to be described later is inserted from either the opening 5a side or the insertion hole 5c side, the external connection member 10 can reasonably be connected to the first and second elastic contact portions 5d, 5e. , And the first and second elastic contact portions 5d and 5e are elastically deformed in the expanding direction.
Therefore, the 1st, 2nd fixed contacts 4 and 6 and the external connection member 10 are connected electrically reliably.

また、第１接続部５の製造方法は、第１接続部５をＵ字状に折り返す前に、プレス加工等で折り返し基部５ｂとなる部分を寸法Ｂで切り欠いて差込孔５ｃを形成し、その後、折り返し基部５ｂをＵ字状に折り返すことで第１接続部５が形成される。
また、折り返し基部５ｂは、切り欠き形成した差込孔５ｃを挟んで互いに対向する連結部５ｆ、５ｆが形成され、この連結部５ｆ、５ｆが略Ｕ時状に折り返されている。前記第２弾接部５ｅは、折り返し基部５ｂを切り欠きする時に、同時に形成されるようになっている。
また、第２固定接点６の第２接続部７は、第１接続部５と同じ構成なので、詳細な説明は省略する。そして、第２接続部７には、開放部７ａ、折り返し部７ｂ、差込孔７ｃ、第１弾接部５ｄ、第２弾接部５ｅ、連結部７ｆがそれぞれ形成されている。 In addition, in the manufacturing method of the first connection portion 5, before the first connection portion 5 is folded back into a U shape, the insertion base 5c is formed by cutting out a portion that becomes the folded base portion 5b by a pressing process or the like with a dimension B. Thereafter, the first connecting portion 5 is formed by folding the folded base portion 5b into a U shape.
Further, the folded base portion 5b is formed with connecting portions 5f and 5f that are opposed to each other with the insertion hole 5c formed in the notch formed therein, and the connecting portions 5f and 5f are folded back in a substantially U-shape. The second elastic contact portion 5e is formed at the same time when the folded base portion 5b is cut out.
Moreover, since the 2nd connection part 7 of the 2nd fixed contact 6 is the same structure as the 1st connection part 5, detailed description is abbreviate | omitted. The second connecting portion 7 is formed with an opening portion 7a, a folded portion 7b, an insertion hole 7c, a first elastic contact portion 5d, a second elastic contact portion 5e, and a connecting portion 7f.

このような第１、第２固定接点４、６は、ウエハ３をケース１の空洞部１ａにスナップ係止すると、ケース１の第１側板１ｂの第１挿通孔１ｇと第１接続部５の開放部５ａとが対峙すると共に、第１側板１ｂの第２挿通孔１ｈと第２接続部７の開放部７ａとが対峙する。
更に、ケース１の第２側板１ｃの第１挿通孔１ｇと第１接続部５の差込孔５ｃとが対峙すると共に、第２側板１ｃの第２挿通孔１ｈと第２接続部７の差込孔７ｃとが対峙する。 The first and second fixed contacts 4 and 6 are configured such that the first insertion hole 1g of the first side plate 1b of the case 1 and the first connection portion 5 are locked when the wafer 3 is snap-locked to the cavity 1a of the case 1. While the opening part 5a opposes, the 2nd penetration hole 1h of the 1st side plate 1b and the opening part 7a of the 2nd connection part 7 oppose.
Furthermore, the first insertion hole 1g of the second side plate 1c of the case 1 and the insertion hole 5c of the first connection portion 5 face each other, and the difference between the second insertion hole 1h of the second side plate 1c and the second connection portion 7 The insertion hole 7c faces.

また、第１、第２固定接点４、６の延出基部４ｂ、６ｂのＵ字状の折り返し根元部が、第１側板１ｂの内面に形成した補強壁１ｍに当接、または近接する。
また、第１、第２固定接点４、６は、ウエハ３に埋設した部分を挟んで第１、第２接点部４ａ、６ａと、第１、第２接続部５、７とが離れた位置に形成されているので、第１、第２接続部５、７に、後述するプラグ等の外部接続部材１０を接続したときに発生する火花等の異物が、第１、第２接点部４ａ、６ａに飛散するのを防止することができる。 Further, the U-shaped folded root portions of the extended base portions 4b and 6b of the first and second fixed contacts 4 and 6 are in contact with or close to the reinforcing wall 1m formed on the inner surface of the first side plate 1b.
Further, the first and second fixed contacts 4 and 6 are positions where the first and second contact portions 4a and 6a and the first and second connection portions 5 and 7 are separated from each other with a portion embedded in the wafer 3 interposed therebetween. Therefore, foreign matters such as sparks generated when an external connection member 10 such as a plug, which will be described later, is connected to the first and second connection portions 5 and 7 are first and second contact portions 4a, It is possible to prevent scattering to 6a.

また、ウエハ３のバネ支持壁３ｂに形成したバネ受け部３ｃには、捻りコイルバネからなる弾性部材８が支持可能になっており、前記弾性部材８は、一端部８ａと他端部８ｂとが所定の角度を有して外側に導出形成されている。
そして、バネ受け部３ｃに弾性部材８を載置すると、一端部８ａがウエハ３のバネ係止部３ｄに嵌合してウエハ３に係止されると共に、他端部８ｂがレバー部材２の右側のストッパ壁２ｃに弾接して、レバー部材２を上方に弾性付勢するようになっている。 An elastic member 8 made of a torsion coil spring can be supported on the spring receiving portion 3c formed on the spring support wall 3b of the wafer 3, and the elastic member 8 has one end 8a and the other end 8b. It is led out to the outside with a predetermined angle.
When the elastic member 8 is placed on the spring receiving portion 3c, one end portion 8a is engaged with the spring engaging portion 3d of the wafer 3 and is engaged with the wafer 3, and the other end portion 8b is engaged with the lever member 2. The lever member 2 is elastically biased upward by elastic contact with the stopper wall 2c on the right side.

また、レバー部材２の接点収納部２ｄ内に形成した空洞部には、リン青銅板等の弾性を有する金属板を略コ字状に折り曲げ形成した可動接点９が収納されている。前記可動接点９は、両端部が連結部９ａ、９ａで連結され、この連結部９ａ、９ａ間にクリップ状の第１、第２接点部９ｂ、９ｃが、第１、第２接点部４ａ、６ａと同じピッチ寸法で形成されている。 A movable contact 9 formed by bending a metal plate having elasticity, such as a phosphor bronze plate, into a substantially U shape is housed in a hollow portion formed in the contact housing portion 2d of the lever member 2. Both ends of the movable contact 9 are connected by connecting portions 9a and 9a, and clip-shaped first and second contact portions 9b and 9c are connected between the connecting portions 9a and 9a, the first and second contact portions 4a, It is formed with the same pitch dimension as 6a.

そして、レバー部材２の接点収納部２ｄ内の空洞部に収納して保持した可動接点９は、動きが規制されて抜け止めされるようになっている。
前記レバー部材２の接点収納部２ｄ内に保持した可動接点９は、レバー部材２の回動操作で、第１接点部９ｂが第１固定接点４の板状の第１接点部４ａを、第２接点部９ｃが第２固定接点６の板状の第２接点部６ａをそれぞれ挟み込んだ状態で、円弧状の第１、第２接点部４ａ、６ａに沿って摺動可能になっている。 The movable contact 9 accommodated and held in the hollow portion in the contact accommodating portion 2d of the lever member 2 is restricted in movement and is prevented from coming off.
The movable contact 9 held in the contact housing portion 2d of the lever member 2 is operated by turning the lever member 2, and the first contact portion 9b changes the plate-like first contact portion 4a of the first fixed contact 4 to the first contact portion 4a. The two contact portions 9c are slidable along the arc-shaped first and second contact portions 4a and 6a in a state where the plate-like second contact portions 6a of the second fixed contacts 6 are sandwiched, respectively.

このような構成の本発明のスイッチ装置の動作を説明すると、まず、レバー部材２を操作する前の初期状態においては、図３に示すように、弾性部材８の付勢力でレバー部材２が上方に回動して、ストッパ壁２ｃがケース１の天板１ｄの天井面に当接した状態になっている。
この初期状態における可動接点９の第１接点部９ｂは、第１固定接点４の第１接点部４ａに接触しており、第２接点部９ｃは、第２固定接点６の第２接点部６ａから離間している。
そのために、第１、第２固定接点４、６は、電気的に不動通状態となっている。 The operation of the switch device of the present invention having such a configuration will be described. First, in an initial state before the lever member 2 is operated, the lever member 2 is moved upward by the biasing force of the elastic member 8 as shown in FIG. The stopper wall 2 c is in contact with the ceiling surface of the top plate 1 d of the case 1.
In this initial state, the first contact portion 9 b of the movable contact 9 is in contact with the first contact portion 4 a of the first fixed contact 4, and the second contact portion 9 c is the second contact portion 6 a of the second fixed contact 6. It is away from.
For this reason, the first and second fixed contacts 4 and 6 are electrically stationary.

前記初期状態において、レバー部材２を矢印Ｃ方向に回動操作すると、図示を省略するが、第２固定接点６の第２接点部６ａに可動接点９の第２接点部９ｃが接触して、第１、第２固定接点４、６が、可動接点９を介して導通し第１、第２固定接点４、６間のスイッチ回路が切り換わってスイッチング動作が行われる。
この時の可動接点９は、レバー部材２の接点収納部２ｄ内の空洞部で動きが規制されているので、レバー部材２の回動操作に確実に連動して回動するので、レバー部材２の回動操作で確実にスイッチ回路を切り換えることができる。 In the initial state, when the lever member 2 is rotated in the direction of the arrow C, the second contact portion 9c of the movable contact 9 comes into contact with the second contact portion 6a of the second fixed contact 6, although illustration is omitted. The first and second fixed contacts 4 and 6 are conducted through the movable contact 9 and the switching circuit between the first and second fixed contacts 4 and 6 is switched to perform the switching operation.
Since the movement of the movable contact 9 at this time is restricted by a hollow portion in the contact housing portion 2d of the lever member 2, the movable contact 9 rotates in conjunction with the rotation operation of the lever member 2 with certainty. The switch circuit can be reliably switched by the turning operation.

また、第１、第２固定接点４、６間のスイッチ回路が切り換わって、矢印Ｃ方向に加えていたレバー部材２の操作荷重を解除すると、レバー部材２は、弾性部材８の付勢力で図３に示す初期状態に自動復帰する。
このことにより、可動接点９の第２接点部９ｃが第２接点部６ａから離間して、スイッチ回路が初期状態に復帰する。
前述したような本発明のスイッチ装置の可動接点９は、レバー部材２の接点収納部２ｄに収納するだけで動きが規制されて抜け止めされるので、組立性に優れていると共に、レバー部材２の回動に忠実に連動して回動することができ、スイッチ回路の切り換えタイミングのバラツキをなくすることができる。 When the switch circuit between the first and second fixed contacts 4 and 6 is switched to release the operation load applied to the lever member 2 in the direction of the arrow C, the lever member 2 is moved by the biasing force of the elastic member 8. It automatically returns to the initial state shown in FIG.
As a result, the second contact portion 9c of the movable contact 9 is separated from the second contact portion 6a, and the switch circuit returns to the initial state.
Since the movable contact 9 of the switch device of the present invention as described above is prevented from coming off by restricting movement only by being housed in the contact housing portion 2d of the lever member 2, the lever member 2 has excellent assemblability. Therefore, it is possible to eliminate the variation in the switching timing of the switch circuit.

このような本発明のスイッチ装置は、図６、図７に示すように、外部のプラグ等の外部接続部材１０を立設した取付部材１１に取付可能になっている。
そして、本発明のスイッチ装置は、左右の第１、第２側板１ｂ、１ｃに形成した第１、第２挿通孔１ｇ、１ｈと、第１、第２固定接点４、６の第１、第２接続部５、７とが対峙しているので、例えば右開閉のドアからなる取付部材１１に取り付けるには、図７に示すように、第２側板１ｃ側を右開閉のドアである取付部材１１と対向させて、第２側板１ｃ側の第１、第２挿通孔１ｇ、１ｈに外部接続部材１０を挿通すると、開放部５ａから外部接続部材１０が侵入して、第１、第２弾接部５ｄ、５ｅに弾接する。 As shown in FIGS. 6 and 7, the switch device of the present invention can be attached to an attachment member 11 provided with an external connection member 10 such as an external plug.
The switch device of the present invention includes the first and second insertion holes 1g and 1h formed in the left and right first and second side plates 1b and 1c, and the first and second fixed contacts 4 and 6, respectively. Since the two connecting portions 5 and 7 are opposed to each other, for example, in order to attach to the attachment member 11 comprising a right opening / closing door, as shown in FIG. 7, the second side plate 1c side is an attachment member that is a right opening / closing door. 11, when the external connection member 10 is inserted into the first and second insertion holes 1g, 1h on the second side plate 1c side, the external connection member 10 enters from the open portion 5a, and the first and second bullets Elastic contact with the contact portions 5d and 5e.

前記外部接続部材１０が第１、第２弾接部５ｄ、５ｅに弾接する時に、第１接続部５が図７において、上部側に押されるが、延出基部４ｂが補強壁１ｍに当接するので、第１固定接点４の変形を防止できる。
また、外部接続部材１０が開放部５ａから侵入して、第１、第２弾接部５ｄ、５ｅに弾接することにより、第１、第２接続部５、７と外部接続部材１０とが接続されとともに、第１、第２位置決め孔１ｊ、１ｋに、取付部材１１側の位置決めピン（図示せず）が嵌合して、本発明のスイッチ装置が取付部材１１の所定位置に位置決めされて取り付けされる。 When the external connection member 10 is in elastic contact with the first and second elastic contact portions 5d and 5e, the first connection portion 5 is pushed upward in FIG. 7, but the extended base portion 4b abuts against the reinforcing wall 1m. Therefore, deformation of the first fixed contact 4 can be prevented.
Further, when the external connection member 10 enters from the open portion 5a and makes elastic contact with the first and second elastic contact portions 5d and 5e, the first and second connection portions 5 and 7 and the external connection member 10 are connected. At the same time, the first and second positioning holes 1j and 1k are fitted with positioning pins (not shown) on the mounting member 11 side, so that the switch device of the present invention is positioned at a predetermined position of the mounting member 11 and mounted. Is done.

また、取付部材１１が、例えば左開閉のドアの場合だと、図６に示すように、左側の第１側板１ｂ側を左開閉のドアである取付部材１１と対向させて、第１側板１ｂ側の第１、第２挿通孔１ｇ、１ｈに外部接続部材１０を挿通することで、第１、第２接続部５、７と外部接続部材１０とを接続することができる。
この時第１接続部５は、挿入してきた外部接続部材１０で図示下方側に押されるが、折り返し基部５ぼ一対の連結部５ｆ、５ｆが第２側板１ｃの内面に当接するので、延出基部４ｂが変形するのを防止できる。 Further, when the attachment member 11 is, for example, a left open / close door, as shown in FIG. 6, the first side plate 1b is arranged with the left first side plate 1b facing the attachment member 11 which is a left open / close door. By inserting the external connection member 10 into the first and second insertion holes 1g and 1h on the side, the first and second connection portions 5 and 7 and the external connection member 10 can be connected.
At this time, the first connecting portion 5 is pushed downward in the figure by the inserted external connecting member 10, but the folded base portion 5 and the pair of connecting portions 5f, 5f abut against the inner surface of the second side plate 1c, so that the first connecting portion 5 extends. The base 4b can be prevented from being deformed.

本発明のスイッチ装置は、姿勢を変えることなく、左右両方向から外部接続部材１０に第１、第２固定接点４、６を接続できるので、１種類で右開閉のドア用と左開閉のドア用とを兼用することができる。
また、補強壁１ｍによって、第１、第２固定接点４、６の延出基部４ｂ、６ｂから折れ曲がって変形するのを防止できる。
尚、本発明の実施の形態では、第１側板１ｂの内面に補強壁１ｍを設けたもので説明したが、第２側板１ｃの内面にも補強壁１ｍを設けたものでも良い。 The switch device of the present invention can connect the first and second fixed contacts 4 and 6 to the external connection member 10 from both the left and right directions without changing the posture. Can also be used.
Further, the reinforcing wall 1m can prevent the first and second fixed contacts 4 and 6 from being bent and deformed from the extended bases 4b and 6b.
