【発明の属する技術分野】
本発明は、圧接コネクタに関し、詳しくは、シールド電線に圧接接続した圧接コネクタを電気機器の圧接コネクタ収容部に収容し、シールド電線と電気機器の内部回路の電気接続を行うものである。
【０００２】
【従来の技術】
従来、特公昭６４−５７５４号において、図８に示す圧接コネクタ１が開示されている。該圧接コネクタ１は、樹脂製のハウジング２と圧接端子金具３とからなり、ハウジング２は、上面と前面とを開放されたキャビテイ２ａを有し、該キャビテイ２ａに圧接端子金具３が収容され、電線４を上面側から押し込んで上方に開いた圧接刃３ａに圧接すると、電線４はハウジング２の前面の開口から延出された状態となる、電線４を圧接した後、相手方コネクタ５のフード部５ａ内に嵌合され、これにより、キャビテイ２ａの上面側の開口が塞がれて圧接端子金具３と電線４との圧接部分が隠された状態となる。上記圧接コネクタ１では、電線４が圧接刃３ａから外れるのを防止するため、ハウジング２の前面の開口に内向きの抜止片２ｂを突設している。

【発明が解決しようとする課題】
上記した圧接コネクタでは、ハウジング２に設けた電線ガイド溝の内部に圧接端子金具３が露出された状態で保持され、圧接端子金具３に圧接接続する電線４はハウジング２の電線ガイド溝を保持された状態で圧接接続される。よって、電線自体をハウジング２で保持された状態となっているが、圧接コネクタの外面に圧接端子金具の圧接刃を突出させ、圧接コネクタの外方で圧接刃で電線の絶縁被覆を切り込んで圧接接続させる場合には、電線の保持手段がないことになる。そのため、作業員あるいは治具で圧接接続箇所の両側を保持した状態で圧接接続させなければならず、作業手数がかかると共に治具を用いる場合には装置が大型化する問題がある。
さらに、圧接コネクタの圧接端子と接続する電線がシールド電線の場合には、該シールド電線のシールド層のアース接続を図る必要があり、通常はシールド層と接続した電線をアースジョイントコネクタに接続する等、作業工程および部品個数が増加する等の問題もある。
【０００５】
本発明は上記問題に鑑みてなされたものであり、圧接コネクタに係止された圧接端子と、該圧接コネクタより離れた位置に配線され、圧接コネクタで保持されない電線とを圧接接続する場合、電線を圧接接続前に保持できるようにすることを第１に課題としている。また、電線がシールド電線である場合に、シールド層とアース接続を容易に行えるようにすることを第２の課題としている。
【０００６】
【課題を解決するための手段】
上記課題を解決するため、本発明は、シールド電線の外側絶縁被覆層（シース）およびシールド層を中間皮剥ぎしてコア線を露出させ、該コア線の芯線に圧接接続させる圧接端子を備えた圧接コネクタであって、
コネクタハウジング内に挿入係止している上記圧接端子の圧接刃を上記コネクタハウジングの外方に突出させ、該圧接刃を貫通させた状態で上記コネクタハウジングの端面に被せるシールド電線押さえ部材を設け、該シールド電線押さえ部材の両側に、上記シールド電線の中間皮剥部を挟む両側部を上下両側より挟持する電線保持部を設け、該両側電線保持部で保持されたシールド電線の中間皮剥部のコア線に上記圧接端子の圧接刃を圧接接続させた状態で、該圧接接続箇所および両側の電線保持部に保護ケースを被せる構成としていることを特徴とする圧接コネクタを提供している。
【０００７】
上記構成とすると、圧接コネクタに取り付けるシールド電線押さえ部材により圧接接続箇所の両側を電線保持部で保持するため、作業員が手で保持する必要がなく、または、治具により電線を押さえる必要もなく、シールド電線の中間皮剥ぎ箇所が弛むことなく保持でき、圧接端子の圧接刃をコア電線の絶縁被覆に精度よく切り込んで、芯線と圧接刃とを圧接接続させることができる。
【０００８】
また、上記シールド電線押さえ部材は導電性金属材より形成し、上記コネクタハウジングの圧接端子突出面に被せる基板部の前面の左右両側より上記電線保持部を前方に突出させていると共に、上記基板部の後面の左右両側より上記コネクタハウジングの両側面を挟持する取付部を後方に突出させ、かつ、該取付部にアース端子部を突設する一方、
上記シールド電線の中間皮剥部では、コア線の露出部の両側のシールド層露出部を設けておき、上記シールド電線押さえ部材の電線保持部でシールド層を挟持し、
電気機器の圧接コネクタ収容部内に上記コネクタハウジングと共に上記シールド電線押さえ部材の取付部を挿入した際に、上記アース端子部を上記電気機器内のアース回路の導電材と電気接続させて、上記シールド電線のシールド層を上記電気機器のアース回路に接続して、シールド層のアース接続をする構成としている。
【０００９】
上記構成とすると、導電性を有するシールド電線押さえ部材の電線保持部がシールド層を接触保持して電気接続でき、かつ、該シールド電線押さえ部材より後方に突設して電気機器のコネクタ収容部内に挿入される取付部の先端のアース端子部が、電気機器内のアース回路の導電材と接続されるため、圧接作業時における電線の保持のために設けた電線保持部によりシールド層のアース接続も簡単に行うことができる。
なお、圧接コネクタの端子収容面に取り付けるシールド電線押さえ部材の基板部は端子収容面の全面を覆う平板状のものに限定されず、両側の電線保持部を連結するものであれば、上枠あるいは／および下枠のみからなるものであってもよい。
【００１０】
上記シールド電線は車載ＬＡＮシステムのＣＡＮケーブルとして好適に用いられ、上記電気機器はＣＡＮケーブルに接続される電子制御部品であることが好ましい。
上記ＣＡＮケーブルとしてシールド電線が用いられる場合が多いため、前記シールド電線のシールド層のアース処理が電子制御部品に取り付けられる圧接コネクタで同時に行える構成とすると、シールド層と接続させたアース電線、該アース電線が接続されるアース用ジョイントコネクタを設ける必要がなくなる。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
図１乃至図７は、本発明の実施形態を示す。
圧接コネクタ１０は、図１に示すように、コネクタハウジング１１のキャビテイ内に収容係止される２つの圧接端子１２（１２Ａ、１２Ｂ）は、先端よりスロット１２ａを切り込んで形成した圧接刃１２ｂをコネクタハウジングの端子挿入面１１ａより外方に突出させている。
上記圧接コネクタ１０は電子制御部品４０に設けたコネクタ収容部４１内に収容係止される。コネクタハウジング１１内の圧接端子１２の他端は雌端子１２ｄとし、電子制御部品４０の内部回路と接続させた雄端子３２をコネクタ収容部４１の底壁より突出させ、雌端子１２ｄと雄端子４２とが雌雄嵌合接続される構成としている。
【００１２】
上記コネクタハウジング１１には導電性金属材より形成したシールド電線押さえ部材１３を組みつけている。該シールド電線押さえ部材１３は、上記圧接端子１２を貫通させた状態でコネクタハウジング１１の端子挿入面１１ａに被せる基板部１３ａと、該基板部１３ａの前面の左右両端より前方へ突出させた上下一対の挟持片からなる電線保持部１３ｂと、基板部１３ａの後面の両側より後方へ突出しコネクタハウジング１１の左右両側面を挟持する取付部１３ｃを備えている。該取付部１３ｃの後端部からアース端子部１３ｄを突設し、圧接コネクタ１０がコネクタ収容部４１に嵌合されると、電子制御部品４０のアース回路の導電材４３に接続されて、シールド電線３０のシールド層３３のアース接続をする構成としている。また、圧接端子１２は基板部１３ａに設けた貫通穴を通し、空隙１４を設けて互いに接触させないようにしている。
【００１３】
さらに、圧接端子１２とシールド電線３０との圧接接続箇所およびシールド電線押さえ部材１３の電線保持部１３ｂに被せる絶縁樹脂製の断面略コ字状の保護ケース２０を設けている。該保護ケース２０は、図２に示すように、先端が開口した収容部２０ａを設けていると共に、先端面に電子制御部品４０側に設けたロック穴４４に挿入係止するロック部２０ｂを突設している。上記保護ケース２０は、圧接端子１２をシールド電線３０に圧接接続させた後に、圧接接続部および電線保持部１３ｂに被せ、この状態で、電子制御部品４０にロック固定している。
【００１４】
上記圧接コネクタ１０の圧接端子１２により圧接接続されるシールド電線３０は、車載ＬＡＮシステムにおいて、電子制御部品同士を接続するＣＡＮケーブルである。該シールド電線３０は、図３に示すように、芯線３１に絶縁被覆層３２を被覆したコア線ｗを２本束ね、この束ねた２本のコア線ｗの外周面を金属メッシュのシールド層３３で被覆し、該シールド層３３の外周面を外側絶縁被覆層（シース）３４で被覆している。
【００１５】
図４に示すように、電子制御部品４０は、上記圧接コネクタ１０のコネクタハウジング１１を収容するコネクタ収容部４１を備え、該コネクタ収容部４１の両側にロック穴４４を設けている。さらに、コネクタ収容部４１には内部回路と接続させた雄端子（タブ）４２と、該雄端子４２の両側に電子制御部品４０内のアース回路の導電材４３を設けている。
【００１６】
次に、シールド電線３０と電子制御部品４０の接続方法について説明する。
先ず、図５に示すように、電子制御部品４０との接続箇所に当たる位置で、シールド電線３０の外側絶縁被覆層３４及びシールド層３３を中間皮剥ぎし、シールド電線３０の２本のコア線ｗを外部に露出させて中間皮剥部３０ａとすると共に、該中間皮剥部３０ａを挟む両側の外側絶縁被覆層３４を皮剥ぎし、シールド層３３を露出させてシールド層露出部３０ｂとしている。
【００１７】
上記シールド電線３０の中間皮剥部３０ａの側方に電子制御部品４０を位置させ、シールド電線押さえ部材１３の電線保持部１３ｂでシールド層露出部３０ｂのシールド層３３を上下から挟持して固定する。
この状態で、圧接コネクタ１０より突出させた圧接端子１２の圧接刃１２ｂでコア線ｗの絶縁被覆層３２を切断して芯線３１と圧接接続させる。
【００１８】
次いで、図７（Ａ）に示すように、シールド電線３０に圧接接続した圧接コネクタ１０のコネクタハウジング１１を電子制御部品４０の圧接コネクタ収容部４１に挿入係止する。この時、圧接端子１２の他端の雌端子１２ｄは圧接コネクタ収容部４１の底面より突出させている雄端子４２と雌雄嵌合接続して、シールド電線３０と電子制御部品４０の内部回路を接続すると共に、シールド電線押さえ部材１３から突出するアース端子部１３ｄは圧接コネクタ収容部４１に設けているアース回路の導電材４３と接続してシールド電線３０のシールド層３３のアース接続をしている。
なお、圧接コネクタ１０を予め電子制御部品４０のコネクタ収容部４１に挿入係止しておき、この状態でシールド電線３０と圧接端子１２とを圧接接続してもよい。
【００１９】
最後に、図７（Ｂ）に示すように、圧接コネクタ１０の圧接端子１２とシールド電線３０とが圧接接続された圧接接続箇所、および、その両側のシールド電線押さえ部材１３の電線保持部１３ｂに保護カバー２０を被せる。該保護カバー２０の先端のロック部２０ｂを圧接コネクタ収容部４１の両側のロック穴４４にロック結合している。
【００２０】
上記構成とすると、シールド電線３０に圧接する圧接端子１２の両側に電線保持部１３ｂを設け、該電線保持部１３ｂによりシールド層３３と接触させながら挟持しているので、シールド電線３０の圧接時にシールド電線３０を固定することができ、圧接精度を向上することができる。
また、圧接コネクタ１０を電子制御部品４０のコネクタ収容部４１に嵌合すると、シールド電線押さえ部材１３に突設したアース端子部１３ｄが電子制御部品４０内のアース回路の導電材４３に接続するため、圧接コネクタ１０によるシールド電線３０と電子制御部品４０との電気接続と共に、シールド層３３のアース接続をすることができる。
なお、本実施形態の圧接コネクタは、上記電子制御部品に限らず、種々の電気機器に採用することができる。
【００２１】
【発明の効果】
以上の説明より明らかなように、本発明によれば、シールド電線押さえ部材を圧接コネクタに組みつけているため、該シールド電線押さえ部材の両側に突設した電線保持部により、シールド電線の圧接接続箇所の両側を上下より挟持することができる。よって、圧接作業時に作業員あるいは治具でシールド電線を押さえて保持する必要がなく、圧接作業を精度良く且つ迅速に行うことができる。
【００２２】
また、上記シールド電線押さえ部材を導電性金属板により形成し、該シールド電線押さえ部材にアース端子を突設すると共に、シールド電線にシールド層露出部を設け、該シールド層露出部のシールド層を電線保持部で接触保持すると、圧接コネクタを電気機器の圧接コネクタ収容部に嵌合した状態で、シールド電線押さえ部材のアース端子と電気機器内のアース回路の導電材とを接続させて、シールド層のアース接続を図ることができる。

Therefore, the electric wire itself is held by the housing 2, but the press-connecting blade of the press-connecting terminal fitting is protruded from the outer surface of the press-connecting connector, and the insulation coating of the wire is cut out by the press-connecting blade outside the press-connecting connector. In the case of connection, there is no means for holding the electric wire. For this reason, it is necessary to press-connect while holding both sides of the press-connecting portion with a worker or a jig, which requires a lot of labor and increases the size of the apparatus when the jig is used.
Further, when the electric wire connected to the press-connecting terminal of the press-connecting connector is a shielded wire, it is necessary to establish the ground connection of the shield layer of the shielded wire. Usually, the wire connected to the shield layer is connected to the ground joint connector. There are also problems such as an increase in the number of work steps and the number of parts.

The present invention has been made in view of the above-described problem, and when a press-connecting terminal that is locked to a press-connector and a wire that is wired at a position distant from the press-connector and that is not held by the press-connector are press-connected, The first problem is to be able to hold the pressure before the pressure connection. A second object is to make it possible to easily connect the shield layer to the ground when the electric wire is a shielded electric wire.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention includes a press contact terminal for exposing a core wire by peeling an outer insulating coating layer (sheath) and a shield layer of a shielded wire to expose a core wire and press-connecting the core wire to the core wire.

Also, the intermediate stripped portion of the shielded wire can be held without loosening, and the press-connecting blade of the press-connecting terminal can be accurately cut into the insulating coating of the core wire to press-connect the core wire and the press-connecting blade.
[0008]
Further, the shield wire holding member is formed of a conductive metal material, and the wire holding portions protrude forward from both left and right sides of the front surface of the board portion which covers the press contact terminal protruding surface of the connector housing. A mounting portion for sandwiching both side surfaces of the connector housing is protruded rearward from both left and right sides of a rear surface, and a ground terminal portion is protruded from the mounting portion,

[0009]
With the above configuration, the wire holding portion of the shielded wire pressing member having conductivity can electrically connect the shield layer by contacting and holding the shield layer, and protrude rearward from the shielded wire pressing member to be inside the connector accommodating portion of the electric device. The ground terminal at the tip of the mounting part to be inserted is connected to the conductive material of the ground circuit in the electrical equipment, so the ground connection of the shield layer is also provided by the wire holding part provided for holding the wire during pressure welding work. Easy to do.
The board portion of the shielded wire pressing member attached to the terminal receiving surface of the press-connecting connector is not limited to a flat plate that covers the entire terminal receiving surface. And / or only the lower frame.
[0010]
The shielded electric wire is preferably used as a CAN cable of an in-vehicle LAN system, and the electric device is preferably an electronic control component connected to the CAN cable.
Since a shielded wire is often used as the CAN cable, if the grounding of the shield layer of the shielded wire can be performed simultaneously by the press-connecting connector attached to the electronic control component, the ground wire connected to the shield layer and the ground It is not necessary to provide a ground joint connector to which the electric wire is connected.
