However, the examples are for understanding the present invention and do not limit the present invention.

図1に示すとおり、本考案の電気自動車の充電延長ケーブルは、家庭用回路と電気自動車充電ガン20の間に連接し、それは延長ケーブル主体を含む。該延長ケーブル主体は、家庭用回路と相互に連接する延長ケーブルプラグ1を含む。該延長ケーブルプラグ1は第一延長ケーブル2で電磁保護スイッチ3を連接する。該電磁保護スイッチ3は、その電流量を制御するのに用い、その電流が大きすぎる時、電磁保護スイッチ3が回路を切断して、延長ケーブル主体に対して保護する。該電磁保護スイッチ3の電流出力端は電気メーター4に連接し、該電気メーター4の電流出力端は、第二延長ケーブル5で延長ケーブルコンセント9を連接し、該延長ケーブルコンセント9は電気自動車充電ガン20と連接するのに用いる。本考案は、電気メーター4を設置することによって、カーオーナーは毎回充電で使用した電気量を直接見ることができる。 As shown in FIG. 1, the electric vehicle charging extension cable of the present invention is connected between a household circuit and an electric vehicle charging gun 20, which includes an extension cable main body. The extension cable main body includes an extension cable plug 1 interconnected with a home circuit. The extension cable plug 1 connects the electromagnetic protection switch 3 with a first extension cable 2.
