Description

本発明は、スイッチ本体と操作レバーとにそれぞれ接点ユニットを有するレバースイッチ装置及びその組立方法に関する。   The present invention relates to a lever switch device having a contact unit on a switch body and an operation lever, respectively, and an assembling method thereof.

従来より、車両用、特に自動車用のレバースイッチ装置においては、スイッチ本体に、操作レバーが支持されると共に、この操作レバーの操作に応動する本体接点ユニットが設けられている。又、操作レバーには、操作ノブが設けられると共に、この操作ノブの操作に応動するレバー接点ユニットが設けられている。そして、そのレバー接点ユニットの固定接点に接続したリード線が、操作レバーの内部に配線されて、スイッチ本体の内部に導入されている。   2. Description of the Related Art Conventionally, in a lever switch device for a vehicle, particularly an automobile, an operation lever is supported on the switch body, and a body contact unit that responds to the operation of the operation lever is provided. The operation lever is provided with an operation knob and a lever contact unit that responds to the operation of the operation knob. A lead wire connected to the fixed contact of the lever contact unit is wired inside the operation lever and introduced into the switch body.

しかしながら、このものによると、リード線をレバー接点ユニットの固定接点に逐一接続する必要があり、コスト高となっていた。
これに対して、上記本体接点ユニットの固定接点と、レバー接点ユニットの固定接点、並びにリード線相当の導通路を、操作レバーに沿って設けるフレキシブルプリント基板の導体パターンで形成する考えがある。
ヨーロッパ公開特許ＥＰ０９１９４３６Ａ１ However, according to this, it is necessary to connect the lead wire to the fixed contact of the lever contact unit one by one, resulting in high cost.
On the other hand, there is an idea of forming a fixed contact of the main body contact unit, a fixed contact of the lever contact unit, and a conductive path corresponding to a lead wire with a conductor pattern of a flexible printed circuit board provided along the operation lever.
European published patent EP0919436A1

上述のように考えられたものの場合、リード線をレバー接点ユニットの固定接点に逐一接続するような必要はなく、コスト安にできる。
しかしながら、フレキシブルプリント基板は、操作レバーの操作に対する耐力が大きくなく、その操作レバーの操作で繰り返し曲げられることに対する耐久性、特には導通路の分断が心配されていた。 In the case of what is considered as described above, it is not necessary to connect the lead wires to the fixed contacts of the lever contact unit one by one, and the cost can be reduced.
However, the flexible printed circuit board is not resistant to the operation of the operation lever, and there is a concern about durability against repeated bending by the operation of the operation lever, in particular, the disconnection of the conduction path.

本発明は上述の事情に鑑みてなされたものであり、従ってその目的は、リード線をレバー接点ユニットの固定接点に逐一接続するような必要がなくて、コスト安にできるばかりでなく、操作レバーの繰り返し操作に対する耐久性にも優れるレバースイッチ装置及びその組立方法を提供するにある。   The present invention has been made in view of the above-described circumstances. Therefore, the object of the present invention is not to connect the lead wires to the fixed contacts of the lever contact unit one by one, and not only can the cost be reduced, but also the operation lever. It is in providing the lever switch apparatus which is excellent also in durability with respect to repetitive operation, and its assembling method.

上記目的を達成するために、本発明のレバースイッチ装置は、スイッチ本体と、このスイッチ本体に支持された操作レバーと、この操作レバーの操作に応動する本体接点ユニットと、前記操作レバーに設けられた操作ノブと、この操作ノブの操作に応動するレバー接点ユニットとを具備するものにおいて、前記本体接点ユニットの固定接点と、前記レバー接点ユニットの固定接点、並びに前記レバー接点ユニットの固定接点から本体接点ユニットの固定接点側に延びる導通路を、前記操作レバーに沿って設けるフレキシブルプリント基板の導体パターンで形成し、このフレキシブルプリント基板の前記導通路を形成した部分を巻回して設けたことを特徴とする（請求項１の発明）。   To achieve the above object, a lever switch device of the present invention is provided in a switch body, an operation lever supported by the switch body, a body contact unit that responds to the operation of the operation lever, and the operation lever. And a lever contact unit that responds to the operation of the operation knob, the fixed contact of the main body contact unit, the fixed contact of the lever contact unit, and the fixed contact of the lever contact unit. A conductive path extending toward the fixed contact side of the contact unit is formed by a conductor pattern of a flexible printed circuit board provided along the operation lever, and a portion of the flexible printed circuit board where the conductive path is formed is wound and provided. (Invention of claim 1)

この場合、フレキシブルプリント基板の導通路を形成した部分は、操作レバーの操作軸心と同心に巻回して設けるとなお良い（請求項２の発明）。
又、組立てに関しては、フレキシブルプリント基板の導通路を形成した部分を巻回して後、その巻回部分からフレキシブルプリント基板を引き出し、この状態で、フレキシブルプリント基板を操作レバーに組み込み、その後に、フレキシブルプリント基板を巻き戻しつつ操作レバーをスイッチ本体に組み付けるようにすると良い（請求項３の発明）。 In this case, the portion of the flexible printed circuit board where the conductive path is formed is preferably provided by being wound concentrically with the operation axis of the operation lever (invention of claim 2).
As for assembly, after winding the portion of the flexible printed circuit board where the conductive path is formed, the flexible printed circuit board is pulled out from the wound part, and in this state, the flexible printed circuit board is assembled into the operation lever, and then the flexible printed circuit board is flexible. The operation lever may be assembled to the switch body while the printed circuit board is rewound (invention of claim 3).

請求項１の発明によれば、本体接点ユニットの固定接点と、レバー接点ユニットの固定接点、並びにレバー接点ユニットの固定接点から本体接点ユニットの固定接点側に延びる導通路を、フレキシブルプリント基板の導体パターンで形成しているから、リード線をレバー接点ユニットの固定接点に逐一接続するような必要がなく、コスト安にできる。そして、操作レバーの繰り返し操作に対して、上記フレキシブルプリント基板は、巻回した部分を伸展させたり巻き戻したりして応動するから、導通路が分断されるような心配もなく、操作レバーの繰り返し操作に対する耐久性にも優れるようにできる。   According to the first aspect of the present invention, the fixed contact of the main body contact unit, the fixed contact of the lever contact unit, and the conduction path extending from the fixed contact of the lever contact unit to the fixed contact side of the main body contact unit are provided on the conductor of the flexible printed circuit board. Since it is formed in a pattern, it is not necessary to connect the lead wires to the fixed contacts of the lever contact unit one by one, and the cost can be reduced. And, since the flexible printed circuit board responds to the repeated operation of the operation lever by extending or rewinding the wound part, there is no concern that the conduction path is broken, and the operation lever is repeated. It can be made to have excellent durability against operation.

請求項２の発明によれば、操作レバーの繰り返し操作が操作軸心を中心に行われることに合わせ、その操作レバーの繰り返し操作に対する耐久性に最も優れるようにできる。
請求項３の発明によれば、巻回したフレキシブルプリント基板が、その巻回した部分を伸展させたり巻き戻したりしてその長さを調整できることに基づき、操作レバーに対するフレキシブルプリント基板の組み込み、並びにそのフレキシブルプリント基板を組み込んだ状態でのスイッチ本体に対する操作レバーの組み付けが難なくできる。 According to the second aspect of the present invention, it is possible to achieve the most excellent durability against the repeated operation of the operation lever in accordance with the repeated operation of the operation lever being performed around the operation axis.
According to the invention of claim 3, based on the fact that the wound flexible printed circuit board can be adjusted in length by extending or rewinding the wound part, The operation lever can be easily assembled to the switch body with the flexible printed circuit board incorporated.

次いで、図８に矢印Ｄで示すように、巻付け胴部１６ａにゆるく巻き付けたフレキシブルプリント基板１０のベルト部１１ｃの部分を引き出す。 Next, as shown by an arrow C in FIG. 7, the winding drum portion 16 a is erected from the thin portion 17 together with the belt portion 11 c of the flexible printed circuit board 10 wound around the winding drum portion 16 a and is engaged with the hook 24 of the inner cover 5. Let it hold.
Next, as shown by an arrow D in FIG. 8, the portion of the belt portion 11c of the flexible printed circuit board 10 that is loosely wound around the winding drum portion 16a is pulled out.

次いで、図９に示すように、操作レバー８のレバーロワー８ａとレバーアッパー８ｂとを、上述の巻付け胴部１６ａより引き出したフレキシブルプリント基板１０のベルト部１１ｃから第２シート部１１ｂにかけた部分を挟んで組立てることにより、フレキシブルプリント基板１０を操作レバー８に沿うように組み込む。   Next, as shown in FIG. 9, a portion where the lever lower 8a and the lever upper 8b of the operation lever 8 are drawn from the belt portion 11c of the flexible printed circuit board 10 drawn from the winding drum portion 16a to the second sheet portion 11b. By assembling, the flexible printed circuit board 10 is assembled along the operation lever 8.

なお、この折り、操作レバー８には、フレキシブルプリント基板１０の第２シート部１１ｂの下に受け板２５を置き、第２シート部１１ｂの上にレバー接点ユニット９の可動接点９ｂを取付けた可動ホルダ１４を置いて、これらをも組み付けている。又、可動ホルダ１４には、図２に示す節度ピース２６とこれに突出力を付与するスプリング２７を組み付けている。   The folding / operating lever 8 is movable by placing a receiving plate 25 under the second sheet portion 11b of the flexible printed circuit board 10 and attaching the movable contact 9b of the lever contact unit 9 on the second sheet portion 11b. These are also assembled by placing the holder 14. Further, the movable holder 14 is assembled with a moderation piece 26 shown in FIG. 2 and a spring 27 for applying a projecting output thereto.

そして、その後、図１０に矢印Ｅで示すように、フレキシブルプリント基板１０のベルト部１１ｃを巻付け胴部１６ａに巻き戻させつつ、操作レバー８をスイッチ本体１の上部１ａに組み付ける。なお、この折り、操作レバー８には、節度ピース２８とこれに突出力を付与するスプリング２９を組み付けている。
又、その後、スイッチ本体１の上部１ａにはベース２を組み付ける。 Then, as indicated by an arrow E in FIG. 10, the operation lever 8 is assembled to the upper portion 1 a of the switch body 1 while the belt portion 11 c of the flexible printed circuit board 10 is rewound onto the winding drum portion 16 a. The folding / operating lever 8 is assembled with a moderation piece 28 and a spring 29 for applying a projecting output thereto.
Thereafter, the base 2 is assembled to the upper part 1a of the switch body 1.

図１は、このようにして組立てたレバースイッチ装置を示しており、可動ブラケット６が軸部３０，３１によって外カバー７と内カバー５とに図の紙面と直交する方向に回動可能に枢支され、操作レバー８が可動ブラケット６に軸部３２によって図で上下に回動可能に枢支されると共に、操作子２２に係合されている。又、可動ブラケット６の節度ピース２０は、外カバー７内の節度谷部３３に圧接し、操作レバー８の節度ピース２８は、可動ブラケット６内の節度谷部３４に圧接している。更に、この場合、巻付け胴部１６ａに巻き付けたフレキシブルプリント基板１０のベルト部１１ｃの部分は、操作レバー８の軸部３０，３１による操作軸心と同心に位置している。   FIG. 1 shows the lever switch device assembled in this way, and the movable bracket 6 is pivoted by the shaft portions 30 and 31 so that the movable cover 6 can rotate in a direction perpendicular to the paper surface of the drawing to the outer cover 7 and the inner cover 5. The operation lever 8 is supported by the movable bracket 6 so as to be pivotable up and down by the shaft portion 32 and is engaged with the operation element 22. The moderation piece 20 of the movable bracket 6 is in pressure contact with the moderation valley portion 33 in the outer cover 7, and the moderation piece 28 of the operation lever 8 is in pressure contact with the moderation valley portion 34 in the movable bracket 6. Further, in this case, the portion of the belt portion 11 c of the flexible printed board 10 wound around the winding body portion 16 a is located concentrically with the operation axis centered by the shaft portions 30 and 31 of the operation lever 8.

従って、今、操作レバー８を図１の紙面と直交する方向に回動操作すれば、可動ブラケット６がそれに伴って同方向に回動し、本体接点ユニット４の第１可動接点４ｂを同方向に移動させて固定接点４ａに接離させる。又、この操作レバー８の図１の紙面と直交する方向の回動に対し、節度ピース２０は節度谷部３３との圧接位置を変えて節度を与える。   Therefore, now, if the operating lever 8 is rotated in the direction orthogonal to the paper surface of FIG. 1, the movable bracket 6 is rotated in the same direction, and the first movable contact 4b of the main body contact unit 4 is moved in the same direction. To move to and away from the fixed contact 4a. Further, with respect to the rotation of the operation lever 8 in the direction orthogonal to the paper surface of FIG.

これに対して、操作レバー８を図１で上下に回動操作すれば、操作子２２が図１で左右に移動されることにより、可動ホルダ１３が同方向に移動し、本体接点ユニット４の第２可動接点４ｃを同方向に移動させて固定接点４ａに接離させる。又、この操作レバー８の図１で上下の回動に対し、節度ピース２８は節度谷部３４との圧接位置を変えて節度を与える。   On the other hand, if the operation lever 8 is turned up and down in FIG. 1, the operating element 22 is moved left and right in FIG. 1, so that the movable holder 13 moves in the same direction, and the main body contact unit 4 The second movable contact 4c is moved in the same direction so as to be in contact with and separated from the fixed contact 4a. Further, the moderation piece 28 changes the pressure contact position with the moderation valley portion 34 to provide moderation with respect to the vertical rotation of the operation lever 8 in FIG.

そして、操作レバー８の先端部において、開口３４から突出した可動ホルダ１４の手懸け部１４ａに指を懸けて該可動ホルダ１４を図１で左右に移動操作すれば、レバー接点ユニット９の可動接点９ｂが同方向に移動して固定接点９ａに接離する。このレバー接点ユニット９の可動接点９ｂが固定接点９ａに接離することによる信号は、フレキシブルプリント基板１０の導通路１２を経てスイッチ本体１部分に送られる。又、この操作レバー８の先端部における可動ホルダ１４の移動に対し、節度ピース２６は操作レバー８内に設けられた図示しない節度谷部との圧接位置を変えて節度を与える。   When the movable holder 14 is moved to the left and right in FIG. 1 by placing a finger on the handle 14a of the movable holder 14 protruding from the opening 34 at the tip of the operation lever 8, the movable contact 9b of the lever contact unit 9 is operated. Moves in the same direction and contacts and separates from the fixed contact 9a. A signal generated when the movable contact 9b of the lever contact unit 9 contacts and separates from the fixed contact 9a is sent to the switch body 1 through the conduction path 12 of the flexible printed circuit board 10. Further, with respect to the movement of the movable holder 14 at the distal end portion of the operation lever 8, the moderation piece 26 changes the pressure contact position with a moderation valley portion (not shown) provided in the operation lever 8 to provide moderation.

このように本構成のものでは、本体接点ユニット４の固定接点４ａと、レバー接点ユニット９の固定接点９ａ、並びにレバー接点ユニット９の固定接点９ａから本体接点ユニット４の固定接点４ａ側に延びる導通路１２を、フレキシブルプリント基板１０の導体パターンで形成している。このものでは、別体のリード線をレバー接点ユニット４の固定接点４ａに逐一接続するような必要がなく、コスト安にできる。   Thus, in this configuration, the fixed contact 4a of the main body contact unit 4, the fixed contact 9a of the lever contact unit 9, and the guide extending from the fixed contact 9a of the lever contact unit 9 to the fixed contact 4a side of the main body contact unit 4 are provided. The passage 12 is formed by the conductor pattern of the flexible printed circuit board 10. In this case, it is not necessary to connect separate lead wires to the fixed contact 4a of the lever contact unit 4, and the cost can be reduced.

そして、フレキシブルプリント基板１０の上記導通路１２を形成した部分は、その一部を巻回して設けている。これにより、操作レバー８の上述の回動操作の繰り返しに対し、上記フレキシブルプリント基板１０が、巻回した部分を伸展させたり巻き戻したりして応動するものであり、よって、導通路１２が分断されるような心配もなく、操作レバー８の繰り返し操作に対する耐久性にも優れるようにできる。   And the part which formed the said conduction | electrical_connection path 12 of the flexible printed circuit board 10 is provided by winding the part. As a result, the flexible printed circuit board 10 responds to the repeated rotation of the operation lever 8 by extending or rewinding the wound portion, so that the conduction path 12 is divided. Therefore, the durability of the operation lever 8 against repeated operations can be improved.

この場合、特に上記構成のものにおいては、フレキシブルプリント基板１０の導通路１２を形成した部分を、操作レバー８の軸部３０，３１による操作軸心と同心に巻回して設けている。これにより、操作レバー８の繰り返し操作が操作軸心を中心に行われることに合わせ、その操作レバー８の繰り返し操作に対する耐久性に最も優れるようにできる。   In this case, particularly in the configuration described above, the portion of the flexible printed circuit board 10 where the conduction path 12 is formed is provided so as to be concentrically wound with the operation axis by the shaft portions 30 and 31 of the operation lever 8. Thereby, it can be made the most excellent in durability with respect to the repeated operation of the operation lever 8 in accordance with the repeated operation of the operation lever 8 being performed around the operation axis.

加えて、上記構成のものの場合、装置の組立てに際しては、フレキシブルプリント基板１０の導通路１２を形成した部分を巻回して後、その巻回部分からフレキシブルプリント基板１０を引き出し、この状態で、フレキシブルプリント基板１０を操作レバー８に組み込み、その後に、フレキシブルプリント基板１０を巻き戻しつつ操作レバー８をスイッチ本体１に組み付けるようにしている。これにより、巻回したフレキシブルプリント基板１０が、その巻回した部分を伸展させたり巻き戻したりしてその長さを調整できることに基づき、操作レバー８に対するフレキシブルプリント基板１０の組み込み、並びにそのフレキシブルプリント基板１０を組み込んだ状態でのスイッチ本体１に対する操作レバー８の組み付けが難なくできる。   In addition, in the case of the above-described configuration, when assembling the apparatus, after winding the portion of the flexible printed circuit board 10 where the conductive path 12 is formed, the flexible printed circuit board 10 is pulled out from the wound section, and in this state, the flexible printed circuit board 10 is flexible. The printed circuit board 10 is assembled into the operation lever 8, and then the operation lever 8 is assembled to the switch body 1 while the flexible printed circuit board 10 is rewound. As a result, the flexible printed circuit board 10 that has been wound can be adjusted in length by extending or rewinding the wound portion, and the flexible printed circuit board 10 can be incorporated into the operation lever 8 and the flexible print circuit The operation lever 8 can be easily assembled to the switch body 1 with the substrate 10 incorporated.
