Description

本発明はコネクタに関し、詳しくは、該コネクタに対向方向から挿入される端子同士を嵌合接続して回路接続を図ると共に、予めコネクタに収容するジョイント端子に一方側から挿入する複数の端子を嵌合してジョイント回路を形成できるコネクタに関するものである。   The present invention relates to a connector. Specifically, terminals inserted from opposite directions are fitted and connected to the connector to achieve circuit connection, and a plurality of terminals to be inserted from one side are fitted into joint terminals previously accommodated in the connector. The present invention relates to a connector that can form a joint circuit.

従来、車両に配索されているワイヤハーネスを構成する電線群のうちで互いに接続してジョイント回路を形成する必要がある場合、図８（Ａ）に示すように、ワイヤハーネスの幹線１００からジョイントする電線を分岐させた枝線１０１を設け、該枝線の先端にジョイントバスバーを収容したジョイントコネクタ１０２を接続し、該ジョイントコネクタ１０２を幹線１００にテープ１０３で巻き付けて固着する場合が多い。   Conventionally, when it is necessary to form a joint circuit by connecting to each other among a group of electric wires constituting a wire harness arranged in a vehicle, as shown in FIG. In many cases, a branch line 101 is formed by branching an electric wire to be connected, a joint connector 102 accommodating a joint bus bar is connected to the end of the branch line, and the joint connector 102 is wound around the main line 100 with a tape 103 and fixed.

また、図８（Ｂ）に示すように、ワイヤハーネスを構成する電線同士をジョイントするのではなく、電線端末の端子同士を嵌合してワイヤーツ−ワイヤーで回路接続する場合もある。この場合、回路接続する電線１０５と１０６とをそれぞれコネクタ１１０と１１１に収容し、コネクタ同士を雌雄嵌合接続し幹線１００の側部に締結バンド１１２で取り付ける場合もある。   Moreover, as shown to FIG. 8 (B), the electric wire which comprises a wire harness may not be jointed, but the terminal of an electric wire terminal may be fitted and it may be circuit-connected by a wire-to-wire. In this case, the electric wires 105 and 106 to be connected to the circuit may be accommodated in the connectors 110 and 111, respectively, and the connectors may be fitted and connected to each other and attached to the side portion of the main line 100 with the fastening band 112.

しかしながら、ワイヤハーネスの幹線の真上や側部にコネクタを取り付ける場合、コネクタ用のスペースが必要となり、密にワイヤハーネスや機器が配置されている領域ではコネクタ用の専用スペースが確保できない場合が多い。
また、図８（Ａ）に示すジョイントコネクタと図８（Ｂ）に示す回路接続用のコネクタの両方をワイヤハーネスに搭載すると、これらコネクタのスペース確保がより困難となる。 However, when a connector is attached directly above or on the side of the main line of the wire harness, a space for the connector is required, and there is often a case where a dedicated space for the connector cannot be secured in an area where the wire harness or the device is densely arranged. .
Further, when both the joint connector shown in FIG. 8A and the circuit connection connector shown in FIG. 8B are mounted on the wire harness, it is more difficult to secure the space for these connectors.

よって、特開平１１−２０４２１８号公報および特開２０１１−８２０２７号公報に開示されたコネクタは回路接続機能とジョイント機能の両方を持たせ、１つのコネクタとすることで設置スペースを小さくできるようにしている。
具体的には、図９に示すように、前記特開平１１−２０４２１８号公報に開示されたコネクタ２００では対向方向から挿入する端子同士２０１と２０２とを雌雄嵌合接続して回路接続をすることを基本としながら、他のキャビテイに、ジョイントバスバー２０５を挿入して、ジョイントコネクタとしての機能も持たせている。 Therefore, the connectors disclosed in JP-A-11-204218 and JP-A-2011-82027 have both a circuit connection function and a joint function so that the installation space can be reduced by using one connector. Yes.
Specifically, as shown in FIG. 9, in the connector 200 disclosed in Japanese Patent Laid-Open No. 11-204218, terminals 201 and 202 inserted from opposite directions are connected by male-female connection for circuit connection. Based on the above, the joint bus bar 205 is inserted into other cavities so as to have a function as a joint connector.

特開平１１−２０４２１８号公報Japanese Patent Laid-Open No. 11-204218 特開２０１１−８２０２７号公報JP 2011-82027 A

前記のように、回路接続用のコネクタの空きキャビテイをジョイント端子同士の接続用として持たせてコネクタの統合を図ると、コネクタの設置スペースを小さくできる。
しかしながら、２個のコネクタをジョイント機能と回路接続機能とを備える１個のコネクタに統合すると、該１個のコネクタは大型化しやすくなり、ワイヤハーネスに取り付けるスペースが確保しにくい問題は解消できない。 As described above, when the cavities of the connectors for connecting the circuits are provided for connecting the joint terminals and the connectors are integrated, the space for installing the connectors can be reduced.
However, when two connectors are integrated into one connector having a joint function and a circuit connection function, the one connector is likely to be enlarged, and the problem that it is difficult to secure a space for attaching to the wire harness cannot be solved.

よって、ワイヤハーネスの枝線端末に取り付けたコネクタを電気制御ユニット等の機器のコネクタ嵌合部に嵌合し、該機器内の回路と接続した端子と接続するコネクタにジョイント機能をもたせると、ワイヤハーネスにコネクタを搭載しないため、スペース確保の問題を解消できる。   Therefore, when the connector attached to the branch end of the wire harness is fitted to the connector fitting portion of the device such as the electric control unit, and the connector connected to the terminal connected to the circuit in the device has a joint function, the wire Since no connector is mounted on the harness, the problem of securing space can be solved.

しかしながら、前記特許文献１のコネクタ２００を、機器のコネクタ嵌合部２２０に収容するコネクタとしては用いることができない。即ち、図１０に示すように、ワイヤハーネスの電線端末の端子挿入前面２１０と対向する背面２１１は平坦面であるため、ジョイントバスバー２０５を背面２１１から挿入すると、ジョイントバスバー２０５のジョイント部２０５ａが背面２１１から突出する。よって、機器のコネクタ嵌合部の底面との間に隙間Ｃが発生してしまい正規位置に嵌合できなくなる。前記特許文献２のコネクタも前記問題に対する配慮はされていない。よって、機器のコネクタ嵌合部に収容して用いる場合には採用できない。   However, the connector 200 of Patent Document 1 cannot be used as a connector that is accommodated in the connector fitting portion 220 of the device. That is, as shown in FIG. 10, since the rear surface 211 facing the terminal insertion front surface 210 of the wire end of the wire harness is a flat surface, when the joint bus bar 205 is inserted from the rear surface 211, the joint portion 205 a of the joint bus bar 205 is Protrudes from 211. Therefore, a gap C is generated between the bottom surface of the connector fitting portion of the device and cannot be fitted at the normal position. The connector of Patent Document 2 also does not consider the above problem. Therefore, it cannot be adopted when used by being accommodated in the connector fitting portion of the device.

また、機器のコネクタ嵌合部に嵌合するコネクタに限定されず、異なるワイヤハーネスの端末に接続されたコネクタ同士をオスーメス嵌合して回路接続する場合においても、一方のコネクタと相手方コネクタとの嵌合面にジョイントバスバーのジョイント部を収容できるスペースがなく、よって、ジョイント部による段差が発生して、正規位置で嵌合できなくなる問題がある。   Moreover, it is not limited to the connector fitted to the connector fitting portion of the device, and even when the connectors connected to the terminals of different wire harnesses are male-female fitted and connected to the circuit, one connector and the other connector There is no space for accommodating the joint portion of the joint bus bar on the fitting surface, and thus there is a problem that a step is generated by the joint portion and the fitting cannot be performed at the normal position.

本発明は前記問題に鑑みてなされたもので、ワイヤハーネス端末に接続するコネクタの空きキャビテイにジョイントバスバーを収容してジョイントコネクタ機能を付設しても、該ジョイントバスバーのジョイント部が相手方端子の挿入側面に段差として突出せず、機器のコネクタ嵌合部または他のワイヤハーネスの端末に接続したコネクタと正規位置で嵌合できるものとすることを課題としている。   The present invention has been made in view of the above problems, and even if the joint bus bar is accommodated in the empty cavity of the connector connected to the wire harness terminal and the joint connector function is provided, the joint portion of the joint bus bar is inserted into the mating terminal. It is an object of the present invention to be able to be fitted at a normal position with a connector connected to a connector fitting portion of an apparatus or a terminal of another wire harness without protruding as a step on the side surface.

前記課題を解決するため、本発明は、ワイヤハーネスの端末に接続されるコネクタであって、該ワイヤハーネスを構成する電線端末に接続される端子を互いに接続するジョイント用端子収容室と、機器または他のワイヤハーネスの相手方回路の端子と嵌合接続する回路接続用端子収容室とをコネクタハウジング内に区分けして設け、
前記電線端末の端子挿入側と対向するコネクタハウジングの背面は、前記ジョイント用端子収容室の背面部分を前記回路接続用端子収容室の背面部分より一段窪ませて形成し、各ジョイント用端子収容室に背面側開口からジョイントバスバーの分岐した端子部を挿入すると共に該ジョイントバスバーのジョイント部は前記背面部分に沿って配置すると共に前記回路接続用端子収容室側の背面部分より突出させず、かつ、該ジョイントバスバーに設けた係止部を前記コネクタハウジングに一体に設けた被係止部と係止してジョイントバスバーを固定していることを特徴とするコネクタを提供している。 In order to solve the above-mentioned problems, the present invention provides a connector connected to a terminal of a wire harness, and a joint terminal receiving chamber for connecting terminals connected to an electric wire terminal constituting the wire harness, A terminal housing chamber for circuit connection to be fitted and connected to the terminal of the other circuit of the other wire harness is provided in the connector housing,
The back surface of the connector housing facing the terminal insertion side of the wire terminal is formed by forming a back surface portion of the joint terminal housing chamber one step below the back surface portion of the circuit connection terminal housing chamber, and each joint terminal housing chamber A joint bus bar branched terminal portion is inserted through the rear side opening, and the joint bus bar joint portion is disposed along the back surface portion and does not protrude from the back surface portion on the circuit connection terminal accommodating chamber side, and There is provided a connector characterized in that a locking portion provided on the joint bus bar is locked with a locked portion provided integrally with the connector housing to fix the joint bus bar.

本発明のワイヤハーネスに接続するコネクタは、ワイヤーツーワイヤーで回路接続するコネクタにジョイントバスバーを取り付けてジョイント機能も付設してコネクタの端子収容室を有効利用している。其の際、ジョイントバスバーを相手方端子の挿入側の背面から取り付けても、該ジョイントバスバーのジョイント部を取り付けるコネクタハウジングの背面を一段窪ませているために突出せず、相手方の機器のコネクタ嵌合部またはメスコネクタからなる相手方コネクタの嵌合面との間に隙間が発生せず、正規位置にコネクタを嵌合することができる。このように、ワイヤーツーワイヤーのコネクタにジョイントコネクタ機能を付設しているため、ワイヤハーネスに接続するコネクタの個数を減少でき、コスト削減および重量低減を図ることができる。   The connector connected to the wire harness of the present invention effectively uses the terminal accommodating chamber of the connector by attaching a joint bus bar to the connector connected by a wire-to-wire circuit and providing a joint function. At that time, even if the joint bus bar is attached from the back side of the mating terminal insertion side, the back of the connector housing to which the joint part of the joint bus bar is attached is not protruded, so the connector fitting of the counterpart device No gap is generated between the mating surface of the mating connector or the mating connector consisting of the female connector and the connector can be fitted in the normal position. Thus, since the joint connector function is attached to the wire-to-wire connector, the number of connectors connected to the wire harness can be reduced, and cost and weight can be reduced.

または、前記ジョイントバスバーの少なくとも１つのジョイント端子部に係止穴を設け、該ジョイント端子部を挿入するジョイント用端子収容室の内面から前記係止穴に挿入係止する係止突起を設けている。 The locking portion provided in the joint bus bar is a locking hole drilled in the joint portion, and a locking projection that is inserted and locked into the locking hole protrudes from the back of the connector housing, or
