例えば太陽光発電システムにおいて、ソーラーパネルから得られた直流電力を交流電力に変換するのに、パワーコンディショナーが用いられている。
このような電源機器を接続するのに、ケーブルが使用されている。
従来は、ケーブルに丸型端子を工具で圧着後に機器の筐体の扉を開け、端子台にネジ締めを行い、結線をしていた。
また、ケーブルを保護するための電線管をつなぎ、防水施工も必要であったために、現場での結線作業が大変であり、高所作業になる場合にはさらに大変であった。 For example, in a photovoltaic power generation system, a power conditioner is used to convert DC power obtained from a solar panel into AC power.
Cables are used to connect such power supplies.
Conventionally, after crimping a round terminal to a cable with a tool, the door of the housing of the device is opened, and the terminal block is screwed to connect the cable.
In addition, since it was necessary to connect conduits to protect the cables and to perform waterproofing work, the wiring work at the site was difficult, and it was even more difficult when the work was done at a high place.

本出願人は、例えば特許文献１及び２等にてケーブル接続作業性，接続信頼性に優れたコネクタを提案している。
本発明は、さらに防水性を付加したコネクタに関する。 The applicant proposes a connector having excellent cable connection workability and connection reliability, for example, in Patent Documents 1 and 2.
The present invention relates to a connector with further waterproofness.
