実用新案登録第２５７３９０９号公報 特開２００３−１２３８８４ 特開２００２−１４１６４５ When connecting the flexible substrate 200 and the external terminal 300, as in the prior art shown in FIG. 9, the first connection part 101A connected to the flexible substrate 200 (pressure contact) and the second connection connected to the external terminal 300 (pressure contact).

(See Patent Document 1).
Utility Model Registration No. 2573909 JP2003-123894A JP 2002-141645 A

図９に示すように、フレキシブル基板２００を基板挿入口１０３Ａに対して鉛直方向に差し込むことによって、ハウジング１０２内に収容されている接続端子１０１の第１接続部１０１Ａとフレキシブル基板２００とを接続するフレキシブル基板用コネクタ１００を使用する場合、フレキシブル基板単体では剛性がなく、基板挿入時に基板が座屈してしまう虞がある。そのため補強板２０１を貼り付けて剛性を確保したフレキシブル基板２００を、基板挿入口１０３Ａに挿入していた。
つまり、従来技術によるフレキシブル基板用コネクタ１００を使用する場合、フレキシブル基板２００に補強板２０１の貼り付けるための作業、及びその部品費用・加工費用などのコストアップが生じるなどの欠点があった。
一方、フレキシブル基板に補強板を貼り付ける必要がないコネクタにおいても、特許文献２に示すようにピアッシングによってフレキシブル基板の端子に外部端子を接続する場合、ピアッシングするためのプレス機やアプリケータが必要であり、特許文献３に示すように溶接によってフレキシブル基板の端子と外部端子を接続する場合、溶接機などの設備が必要であり、大掛かりな設備を要するといった問題点があった。さらに接続に要するスペース（ピアッシング部、溶接部）のため端子全長が大きくなり、コネクタ全体の大型化を招く要因となっていた。 As shown in FIG. 9, the flexible substrate 200 is inserted in the vertical direction with respect to the substrate insertion opening 103 </ b> A to connect the first connection portion 101 </ b> A of the connection terminal 101 accommodated in the housing 102 and the flexible substrate 200. When the flexible substrate connector 100 is used, the flexible substrate alone is not rigid and the substrate may be buckled when the substrate is inserted. For this reason, the flexible substrate 200 having the rigidity secured by attaching the reinforcing plate 201 is inserted into the substrate insertion opening 103A.
That is, when the flexible substrate connector 100 according to the prior art is used, there are disadvantages such as work for attaching the reinforcing plate 201 to the flexible substrate 200 and cost increase such as component costs and processing costs.
On the other hand, even in a connector that does not require a reinforcing plate to be attached to a flexible board, as shown in Patent Document 2, when connecting an external terminal to a terminal of the flexible board by piercing, a press machine or applicator for piercing is required. In addition, as shown in Patent Document 3, when a terminal of a flexible substrate and an external terminal are connected by welding, there is a problem that equipment such as a welding machine is necessary and large equipment is required. In addition, the space required for connection (piercing portion, welded portion) increases the overall length of the terminal, leading to an increase in the size of the entire connector.

そこで本発明は、フレキシブル基板に補強板を貼り付けることなくコネクタとフレキシブル基板の接続を図ることができるフレキシブル基板用コネクタを提供することを目的とする。   Then, an object of this invention is to provide the connector for flexible substrates which can aim at the connection of a connector and a flexible substrate, without sticking a reinforcement board to a flexible substrate.

上述の目的を達成するため、本発明は、フレキシブル基板に接続される第１接続部と外部端子に接続される第２接続部とを有する接続端子と、前記接続端子を収容するハウジングと、前記ハウジングの一端側の開口を開閉するカバーとから構成されるフレキシブル基板用コネクタにおいて、前記開口を閉じたカバーの内周面に対峙するように配置された第１接続部に、前記カバーの内周面でフレキシブル基板を押し付けることによって、フレキシブル基板の端子を第１接続部に圧接し、接続端子とフレキシブル基板とを接続するものである。   In order to achieve the above object, the present invention provides a connection terminal having a first connection part connected to a flexible substrate and a second connection part connected to an external terminal, a housing for housing the connection terminal, In the connector for a flexible substrate comprising a cover that opens and closes an opening on one end side of the housing, the inner periphery of the cover is connected to a first connection portion that is disposed so as to face the inner peripheral surface of the cover with the opening closed. By pressing the flexible substrate on the surface, the terminal of the flexible substrate is pressed against the first connection portion, and the connection terminal and the flexible substrate are connected.

本発明によるフレキシブル基板用コネクタによれば、開口を閉じたカバーの内周面に対峙するように配置された第１接続部に、前記カバーの内周面でフレキシブル基板を押し付けることによって、フレキシブル基板の端子を第１接続部に圧接するため、補強板を貼り付けることなく、コネクタにフレキシブル基板を実装することができる。
またピアッシングや溶接をすることなく、ハウジングの開口をカバーで閉じる際に、当該カバーの内周面でフレキシブル基板を第１接続部に押し付けるようにして、フレキシブル基板の端子と接続端子とを接続するため、溶接設備等が不要でありコストダウンを図ることができるとともに、接続に要するスペース（ピアッシング部、溶接部）が不要であり、コネクタの小型化が可能である。
さらにこの発明によるフレキシブル基板用コネクタでは、ハウジングの開口をカバーで閉じることによって、フレキシブル基板が前記カバーの内周面で第１接続部に押し付けられるため、フレキシブル基板の端子とコネクタの接続端子との強固な接続を図ることができ、電気的導通性の信頼性が高い。 According to the flexible substrate connector of the present invention, the flexible substrate is pressed by pressing the flexible substrate on the inner peripheral surface of the cover against the first connection portion disposed so as to face the inner peripheral surface of the cover with the opening closed. Since the terminal is pressed against the first connecting portion, the flexible board can be mounted on the connector without attaching a reinforcing plate.
Further, when closing the opening of the housing with the cover without piercing or welding, the flexible substrate is pressed against the first connection portion on the inner peripheral surface of the cover, thereby connecting the terminal of the flexible substrate and the connection terminal. This eliminates the need for welding equipment and the like, reduces costs, and eliminates the space required for connection (piercing portion and welded portion), thereby enabling a reduction in the size of the connector.
Furthermore, in the connector for a flexible substrate according to the present invention, the flexible substrate is pressed against the first connection portion on the inner peripheral surface of the cover by closing the opening of the housing with the cover, so that the terminal of the flexible substrate and the connection terminal of the connector A strong connection can be achieved and the reliability of electrical continuity is high.
