車載用スイッチや補機は特許公報１，２の先行技術文献に示されたような構造となっており、自動車に用いられている標準的なコネクタと一体化されている。車載用スイッチや補機を標準品として大量生産し、コストダウンを図るには有効な手段で、実際に多くの自動車で使用されているが、デザインや設計上の制約から、薄型化の要請が生じた場合に、コネクタ部分を別体化したいような場合に対応が困難である。また、そのような特殊な用途のために新規に樹脂部品用の金型を起工して、新しい車載用スイッチや補機を設計しなおすのはコスト面で対応が困難であるという問題がある。さらには自動車メーカーや自動車部品メーカーの部品種類を増加させることで、品番管理コストを引き上げるという問題も生じる。ここで、スイッチや補機の組み合わせを任意に行おうとした場合、スイッチのキートップの交換やスイッチ自体を置き換えることになるが、追加・変更を行おうとする場合にはスイッチ背後にコネクタ結合用の電線余長を収納するスペースが必要であるため実現が困難であるという問題がある。   The in-vehicle switch and the auxiliary machine have a structure as shown in the prior art documents of Patent Publications 1 and 2, and are integrated with a standard connector used in an automobile. This is an effective way to reduce the cost by mass-producing in-vehicle switches and auxiliary equipment as standard products, and is actually used in many automobiles. When it occurs, it is difficult to cope with the case where it is desired to separate the connector portion. In addition, there is a problem that it is difficult to cope with cost in order to start a new mold for resin parts and redesign a new in-vehicle switch or auxiliary machine for such a special application. Furthermore, there is a problem of increasing the part number management cost by increasing the types of parts of automobile manufacturers and automobile parts manufacturers. Here, if any combination of switches and auxiliaries is attempted, the switch key tops will be replaced or the switches themselves will be replaced. There is a problem that it is difficult to realize because a space for storing the extra wire length is required.

そこで、本発明は、薄型にし、省スペースを図り、かつ任意の組み合わせを可能としたフレキシブル配線基板を用いた電気接続構造を提供することを目的とする。   Therefore, an object of the present invention is to provide an electrical connection structure using a flexible wiring board that is thin, saves space, and can be arbitrarily combined.

上述の目的を達成するため、本発明は、操作部を備えた本体部に操作部の操作により作動する部品が実装されたフレキシブル配線基板を組み付け、前記フレキシブル配線基板を本体部から外部へ延出してその配線を車両側電線とコネクタを介して接続したものである。   In order to achieve the above-described object, the present invention assembles a flexible wiring board on which a component that is operated by operation of an operation part is mounted on a main body part having an operation part, and extends the flexible wiring board from the main body part to the outside. The wiring is connected to the vehicle-side electric wire via a connector.

本発明によれば、操作部を備えた本体部に操作部の操作により作動する部品が実装されたフレキシブル配線基板を組み付け、前記フレキシブル配線基板を本体部から外部へ延出してその配線を車両側電線とコネクタを介して接続したので、コネクタをスイッチや補機とは別体にでき、薄型にし、省スペースを実現することができるのみならず、任意の組み合わせも可能である。   According to the present invention, a flexible wiring board on which a component that is operated by operation of the operation unit is mounted is assembled to a main body unit having an operation unit, and the flexible wiring board is extended from the main body unit to the outside so that the wiring is connected to the vehicle side. Since the electric wire and the connector are connected, the connector can be separated from the switch and the auxiliary machine, and not only can the thickness be reduced and the space can be saved, but also any combination is possible.

以下に、本発明の実施形態について、図面を参照しつつ説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１に示す電気接続構造は、スイッチに適用した例を示し、表面に操作部２、裏面に一対の脚部３を備えた本体部１に台座４とフレキシブル配線基板５とを組み付けたものである。この台座４とフレキシブル配線基板５とは、本体部１の一対の脚部３間にセットされる。前記フレキシブル配線基板５には、操作部２の操作により作動するスイッチ要素（部品）６やその他必要な部品が実装されている。フレキシブル配線基板５に実装されるその他の部品としては、例えば負荷駆動用のリレー装置、このリレー装置の動作を制御する制御回路装置などである。前記台座４は、フレキシブル配線基板５を載置するためのものである。従来は、このような本体部１の裏側に、コネクタ付スイッチ装置を組み付けていたので、コネクタは常にスイッチ装置と一体であった。本発明では、スイッチ要素や他の部品６が実装されたフレキシブル配線基板５を本体部１から外部へ延出し、すなわち両脚部３間の開口３Ａから引き出し、この引き出された延出部分５Ａの端部において車両側電線（ワイヤハーネス）８（後述する）と電気的接続を図ることができる。   The electrical connection structure shown in FIG. 1 shows an example applied to a switch, in which a base 4 and a flexible wiring board 5 are assembled to a main body 1 having an operation unit 2 on the front surface and a pair of legs 3 on the back surface. is there. The base 4 and the flexible wiring board 5 are set between the pair of legs 3 of the main body 1. On the flexible wiring board 5, a switch element (component) 6 that is activated by the operation of the operation unit 2 and other necessary components are mounted. Examples of other components mounted on the flexible wiring board 5 include a relay device for driving a load and a control circuit device for controlling the operation of the relay device. The pedestal 4 is for mounting the flexible wiring board 5. Conventionally, since a switch device with a connector is assembled on the back side of the main body 1 as described above, the connector is always integrated with the switch device. In the present invention, the flexible wiring board 5 on which the switch element and other components 6 are mounted is extended from the main body 1 to the outside, that is, pulled out from the opening 3A between the legs 3, and the end of the extended portion 5A thus drawn out. In this part, electrical connection with the vehicle-side electric wire (wire harness) 8 (described later) can be achieved.

図２は、本体部１、部品６を実装したフレキシブル配線基板５、台座４の組み付け順序を示す。図３は、フレキシブル配線基板５の延出部分５Ａにコネクタ端子７を設け、このコネクタ端子７を車両側電源からのワイヤハーネス８が接続されたコネクタ９に接続し、フレキシブル配線基板５（５Ａ）に形成された配線を介して部品６（スイッチ素子やその他の実装部品）との電気的接続を図った状態を示す。前記フレキシブル配線基板５は、薄くて可撓性を有するので、本体部１の脚部３間から外部に引き出され、設置場所の状況によっては湾曲させて配索することも可能である。   FIG. 2 shows the assembly order of the main body 1, the flexible wiring board 5 on which the component 6 is mounted, and the pedestal 4. FIG. 3 shows that a connector terminal 7 is provided on the extended portion 5A of the flexible wiring board 5, and this connector terminal 7 is connected to a connector 9 to which a wire harness 8 from a vehicle-side power source is connected. The flexible wiring board 5 (5A) The state which aimed at the electrical connection with the components 6 (switch element and other mounting components) via the wiring formed in FIG. Since the flexible wiring board 5 is thin and flexible, it can be drawn out from between the legs 3 of the main body 1 and curvedly arranged depending on the installation location.

図４は、３つの本体部１に対して１つのフレキシブル配線基板５を用い、この基板５の部品６の実装部分を３つに分離させたものであり、基端側で連結され、基板部分５Ａからコネクタ端子７、コネクタ９及びワイヤハーネス８を介して車両側電源に電気的に接続されている。この例では、３つの台座４を連結板４０で連結して用いたが、個別にそれぞれの台座４をそれぞれの脚部３間に組み付けてもよい。   FIG. 4 shows a configuration in which one flexible wiring board 5 is used for three main body parts 1 and mounting parts of components 6 of this board 5 are separated into three parts, which are connected at the base end side, 5A through the connector terminal 7, the connector 9 and the wire harness 8 are electrically connected to the vehicle-side power source. In this example, the three pedestals 4 are connected by the connecting plate 40, but each pedestal 4 may be individually assembled between the respective leg portions 3.

図５に示す実施形態は、本体部１の脚部３の両側面にも開口３Ｂを形成し、この開口３Ｂからフレキシブル配線基板５の延出部分５Ａを外部に引き出すものである。図６は、開口３Ｂから延出部分５Ａを引き出すタイプの複数例であり、３つの本体部１に３つの部品６が対応し、３つの台座４が各部品６の下に置かれる。   In the embodiment shown in FIG. 5, openings 3B are formed on both side surfaces of the leg portion 3 of the main body 1 and the extending portion 5A of the flexible wiring board 5 is drawn out from the opening 3B. FIG. 6 shows a plurality of examples in which the extending portion 5 </ b> A is drawn out from the opening 3 </ b> B. Three parts 6 correspond to the three main body portions 1, and three pedestals 4 are placed under the parts 6.

図７及び図８は、コネクタ端子７としてカードエッジコネクタを用いたものを示し、このコネクタ端子７を配線基板５０に実装したコネクタ１０に接続するようにした。この配線基板５０の配線は、ワイヤハーネス８とコネクタ９を介して電気的に接続される。この配線基板５０はソリッドなものでもフレキシブルなものでもよいが、薄さや配索の自由度を考えればフレキシブル配線基板が望ましく、この基板５０にも必要な部品が実装される。また、ワイヤハーネス８と接続するコネクタ９もカードエッジ型とすることも可能である。   FIGS. 7 and 8 show a connector using a card edge connector as the connector terminal 7, and the connector terminal 7 is connected to the connector 10 mounted on the wiring board 50. The wiring of this wiring board 50 is electrically connected via the wire harness 8 and the connector 9. The wiring board 50 may be solid or flexible, but a flexible wiring board is desirable in view of thinness and freedom of wiring, and necessary components are also mounted on the board 50. The connector 9 connected to the wire harness 8 can also be a card edge type.

上述した各実施形態では、車載用スイッチを例として示したが、他にも超音波センサや温度センサなどのセンサ類、モーターなどのアクチュエータについても同様の構造を採用することで、薄型化の要請に対応することができる。また、フレキシブル配線基板５を配線材として利用することによって、複数のスイッチの場合でも容易に配線の統合を図ることができる。１枚の部品実装フレキシブル配線基板５上に複数のスイッチ回路を統合することによって、コネクタ個別の配線を廃止し、フレキシブル配線基板５による一括接続を実現することが可能となる。また台座４を統合（つなぎ合わせる）することによって、スイッチ本体を統合し、スイッチ取り付け工数の削減を図ることも可能となる。   In each of the above-described embodiments, the in-vehicle switch has been shown as an example. However, other sensors such as ultrasonic sensors and temperature sensors, and actuators such as motors can be used to reduce the thickness. It can correspond to. Further, by using the flexible wiring board 5 as a wiring material, wiring can be easily integrated even in the case of a plurality of switches. By integrating a plurality of switch circuits on one component-mounted flexible wiring board 5, it is possible to eliminate wiring for each connector and realize collective connection by the flexible wiring board 5. Also, by integrating (connecting) the bases 4, it is possible to integrate the switch main body and reduce the number of switch mounting steps.
