Description

本発明は、ジョイントコネクタおよびワイヤハーネスに関する。   The present invention relates to a joint connector and a wire harness.

従来、電線群または電線群を被覆する外装材にジョイントコネクタを取り付けたワイヤハーネスがある。   Conventionally, there is a wire harness in which a joint connector is attached to an electric wire group or an exterior material covering the electric wire group.

例えば、電線群または外装材に直方体状のジョイントコネクタを、粘着テープを用いて固定したとすると、粘着テープが経年劣化することによりジョイントコネクタの位置がずれることや、あるいはジョイントコネクタが脱落することが懸念される。また、直方体状のジョイントコネクタを電線群または外装材に固定すると、配索スペースが小さい個所ではジョイントコネクタが他の部品と干渉するという問題があった。   For example, if a rectangular parallelepiped joint connector is fixed to an electric wire group or exterior material using an adhesive tape, the position of the joint connector may shift due to deterioration of the adhesive tape over time, or the joint connector may fall off. Concerned. Further, when the rectangular parallelepiped joint connector is fixed to the electric wire group or the exterior member, there is a problem that the joint connector interferes with other parts in a place where the wiring space is small.

ジョイントコネクタの位置がずれることや、あるいはジョイントコネクタが脱落することが生じないようにするため、ワイヤハーネスにバンドクランプを巻き付け、このバンドクランプのバンドにロック手段を介してジョイントコネクタを固定するよう構成したジョイントコネクタが既に知られている(例えば、特許文献1参照)。   In order to prevent the position of the joint connector from shifting or the joint connector from falling off, a band clamp is wound around the wire harness, and the joint connector is fixed to the band clamp band via a locking means. Such a joint connector is already known (see, for example, Patent Document 1).

また、配索スペースが小さい個所でジョイントコネクタが他の部品と干渉しないようにするため、互いに軸方向に嵌合可能な環状の第1コネクタおよび第2コネクタにより構成したジョイントコネクタが既に知られている(例えば、特許文献2参照)。   Further, in order to prevent the joint connector from interfering with other parts in a place where the wiring space is small, a joint connector constituted by an annular first connector and a second connector that can be fitted in the axial direction is already known. (For example, refer to Patent Document 2).

特許文献2における第1コネクタおよび第2コネクタは、電線群を周方向に取り囲むようになっている。第1コネクタは、それぞれ半環状に形成された一対のハウジングと、各ハウジングに設けた端子とを備えている。第2のコネクタは、それぞれ半環状に形成された一対のハウジングと、各ハウジングに設けたバスバーとを備えている。   The 1st connector and 2nd connector in patent documents 2 surround the electric wire group in the peripheral direction. The first connector includes a pair of housings each formed in a semi-annular shape and terminals provided in each housing. The second connector includes a pair of housings each formed in a semi-annular shape and a bus bar provided in each housing.

しかしながら、特許文献1に記載されたものは、電線群がコルゲートチューブに外装されていると、コルゲートチューブに巻き付けられるバンドクランプがコルゲートチューブの溝に沿ってチューブ周方向にずれることが懸念される。   However, what is described in Patent Document 1 is concerned that when the wire group is sheathed on the corrugated tube, the band clamp wound around the corrugated tube may shift in the tube circumferential direction along the groove of the corrugated tube.

また、特許文献2に記載されたものは、部品点数が多く、第2コネクタにおける一方のハウジングに設けたバスバーと、第2コネクタにおける他方のハウジングに設けたバスバーとが電気的に接続されていないので、導通が取れる電線の本数が少ない。さらに、特許文献2に記載されたものは、第1コネクタと第2コネクタとの2つの物品に分割されているので、取り付け工数や製作コストが高くなり、部品管理も煩雑となる問題があった。   Moreover, what was described in patent document 2 has many components, and the bus bar provided in one housing in the 2nd connector and the bus bar provided in the other housing in the 2nd connector are not electrically connected. Therefore, the number of wires that can be connected is small. Furthermore, since what is described in Patent Document 2 is divided into two articles, a first connector and a second connector, there are problems in that the number of mounting steps and the manufacturing cost increase, and the parts management becomes complicated. .
