Description

本発明は、コンタクト端子にケーブルの芯線を結線したコネクタに関する。   The present invention relates to a connector in which a core wire of a cable is connected to a contact terminal.

例えば、複数のソーラーパネルを中継コネクタを用いて制御部等とケーブル接続する場合に、これまではソーラーパネル等の設置現場にてケーブルの芯線を専用圧着工具によりターミナルに結線していた。
これでは現場での結線作業が大変であり、特に高所作業になると専用工具等を落下させる恐れもあった。
そこで本出願人は、先にケーブルの結線作業性に優れたコネクタを提案している（特許文献１）。
本発明は、さらに結線作業性の向上を目的に本発明に至った。 For example, when connecting a plurality of solar panels to a control unit or the like using a relay connector, the core wire of the cable has been connected to the terminal with a dedicated crimping tool at the installation site of the solar panel or the like.
This makes the wiring work on site difficult, and there is a risk of dropping a dedicated tool or the like particularly when working at a high place.
Therefore, the present applicant has previously proposed a connector excellent in cable connection workability (Patent Document 1).
The present invention has reached the present invention for the purpose of further improving the wiring workability.

特願２０１３−２３０７４４号Japanese Patent Application No. 2013-230744

本発明は、ケーブルの結線作業性に優れ、接続信頼性の高いケーブル接続用コネクタの提供を目的とする。   It is an object of the present invention to provide a cable connection connector that has excellent cable connection workability and high connection reliability.

本発明に係るケーブル接続用コネクタは、コンタクト端子、結線部材及び開放部材をハウジング内に収容してあり、前記結線部材はケーブルの芯線を前記コンタクト端子に弾性付勢力にて直接又は間接的に結線する結線部を有し、前記開放部材は前記結線部材の弾性付勢力に対抗して前記結線部を開放状態に仮保持するためのものであり、前記結線部を開放部材にて開放状態にした状態でコンタクト端子と結線部との間にケーブルの芯線を挿入し、前記ハウジングに設けた開閉自在の上ケースを閉じると前記上ケースに設けた結線作動部が前記開放部材の仮保持状態を解除し、ケーブルの芯線がコンタクト端子に結線されるものであることを特徴とする。
ここでコンタクト端子には、ソケット端子、プラグ端子等が含まれる。
開放部材とは、ケーブルの芯線をコンタクト端子に直接又は間接的に結線する際に、このケーブルの芯線をコンタクト端子と結線部材に設けた結線部材との間に挿入しやすいように、この結線部が芯線に係止しないように結線部材の弾性付勢力に対抗して、開放状態にしておくためのものである。
また、ケーブルの芯線をコンタクト端子に直接又は間接的に結線すると表現したのは、ケーブルの芯線をコンタクト端子に電気接続する際にケーブルの芯線を直接コンタクト端子に接触させる場合のみならず、間に他の端子を挟み込み電気接続する場合も含める趣旨である。
本発明のコネクタは、例えばソーラーパネル等のケーブル接続に用いられるコネクタのみならずケーブルを電気接続するのに用いられる各種コネクタも含まれる。 The connector for cable connection according to the present invention has a contact terminal, a connecting member, and an opening member accommodated in a housing, and the connecting member connects the core wire of the cable directly or indirectly to the contact terminal with an elastic biasing force. The opening member is for temporarily holding the connecting portion in an open state against the elastic biasing force of the connecting member, and the connecting portion is opened by the opening member. When the cable core wire is inserted between the contact terminal and the connection part in the state, and the upper case that can be opened and closed is closed, the connection operation part provided in the upper case releases the temporary holding state of the release member. The cable core wire is connected to the contact terminal.
Here, the contact terminals include socket terminals, plug terminals, and the like.
The open member means that when connecting the cable core wire directly or indirectly to the contact terminal, this cable connecting portion is provided so that the cable core wire can be easily inserted between the contact terminal and the connection member provided on the connection member. This is for keeping the wire member open against the elastic biasing force of the connecting member so as not to be locked to the core wire.
In addition, the expression that the cable core wire is directly or indirectly connected to the contact terminal is not only when the cable core wire is directly connected to the contact terminal when electrically connecting the cable core wire to the contact terminal. It is intended to include the case where other terminals are sandwiched and electrically connected.
The connector of the present invention includes not only a connector used for connecting a cable such as a solar panel but also various connectors used for electrically connecting a cable.

本発明はハウジングにケーブルを挿入し、上ケースを閉じるだけで結線が完了する点に特徴がある。
その態様としては、前記結線部材の結線部は結線方向に弾性付勢された弾性片に形成してあり、前記開放部材は弾性付勢力に対抗して結線部が開放状態になるように前記弾性片を載置することで仮保持できる立設部を有し、前記上ケースに設けた結線作動部は上ケースを閉じると弾性片を立設部から外れる方向に押圧移動させるものである場合を例として挙げることができる。
さらに具体的には、前記弾性片はケーブルの芯線を挿入する開口部を有するとともに開口部の端部に結線部を形成してあり、前記開放部材の立設部に前記開口部の端部に形成した結線部を載置することで開放状態にでき、前記上ケースに設けた結線作動部は上ケースを閉じると前記立設部に載置した結線部を立設部から外れる方向に前記弾性片を押圧移動させるものである態様が挙げられる。 The present invention is characterized in that the connection is completed simply by inserting the cable into the housing and closing the upper case.
As a form thereof, the connecting portion of the connecting member is formed as an elastic piece elastically urged in the connecting direction, and the opening member is elastic so that the connecting portion is opened against the elastic urging force. There is a standing part that can be temporarily held by placing a piece, and the connection actuating part provided in the upper case presses and moves the elastic piece in a direction away from the standing part when the upper case is closed. As an example.
More specifically, the elastic piece has an opening for inserting the core wire of the cable, and a connection portion is formed at the end of the opening, and the standing portion of the opening member is provided at the end of the opening. The formed connection part can be opened by placing it, and the connection actuating part provided in the upper case is elastic in the direction in which the connection part placed on the standing part is detached from the standing part when the upper case is closed. An embodiment in which the piece is pressed and moved is exemplified.

本発明において、前記ハウジングはケーブルを当該ハウジングに挿入した状態を弾性保持するためのケーブル保持部材を有するようにしてもよい。
このようにすると、上ケースを閉じる前に不本意にケーブルがハウジングから抜けるのを防止する。 In the present invention, the housing may have a cable holding member for elastically holding a state where the cable is inserted into the housing.
This prevents the cable from unintentionally coming out of the housing before closing the upper case.

本発明に係るコネクタは、結線部の弾性付勢力が開放された状態でコンタクト端子と結線部との間にケーブルの芯線を挿入するので容易に挿入でき、その状態でハウジングの上ケースを閉じるだけで開放状態が解除され、結線状態になるので従来の手作業による解除に比較して接続の信頼性が高い。   The connector according to the present invention can be easily inserted because the core wire of the cable is inserted between the contact terminal and the connection portion in a state where the elastic biasing force of the connection portion is released, and only the upper case of the housing is closed in that state. Since the open state is released and the connection state is established, the connection reliability is higher than that of the conventional manual release.

It is placed on the placement portion 14b and temporarily held open.
In this state, the core wire 1a of the cable 1 is inserted between the contact terminal 12 and the connection portion 13d through the opening 13c in the state of FIG.
At this time, the contact portion 14c of the opening member 14 is in elastic contact with the core wire 1a, the covering portion of the cable 1 is elastically held by the cable holding member 15, and the outer peripheral portion is sealed by the seal piece 16a.
Next, when the upper case 11c is closed, as shown in FIGS. 1C and 1D, the connection operation part 11f enters through the window part 11j, and the tip slope portion of the connection operation part 11f is the elastic piece 13b. The elastic piece 13b moves rearward by being in sliding contact with the curved surface portion 13e at the upper end, and the connection portion 13d temporarily held by the placement portion 14b is detached from the placement portion 14b.
Thereby, the elastic piece 13b returns downward by the elastic restoring force, and the connecting portion 13d is locked to the upper side portion of the core wire 1a to be connected.
When it is desired to remove the cable 1 from the connector 10, as shown in FIG. 1 (e), the upper case 11c is opened, the tip of a tool 2 such as a screwdriver is inserted from the window portion 11j, the elastic piece 13b is pulled upward, and the connection is made. The portion 13d may be placed on the placement portion 14b of the opening member 14.
