Small onboard electric leakage sensor and charging pile using same

The utility model discloses a small onboard electric leakage sensor and a charging pile using the same. The electric leakage sensor mainly solves the problem that shells of existing electric leakage sensors are connected through buckles, and installation is not stable. The utility model relates to an electric leakage detection device, which is characterized by comprising a main shell (1) and at least one auxiliary shell (2), an electric leakage detection assembly (3) is arranged in the main shell, a through hole (21) for a lead to pass through is arranged on the auxiliary shell, the electric leakage detection device further comprises a connecting rivet (4), and the main shell and the at least one auxiliary shell are fixedly connected together through the connecting rivet. The small onboard leakage sensor and the charging pile using the same provided by the utility model are installed through rivets, and after installation, the structure is stable and the small onboard leakage sensor is not easy to fall off. 一
