AI Technical Summary

Technical Problem

The insulation detection method of the existing new energy vehicle charging interface is inconvenient to operate, and the operator needs to hold a megohmmeter and a test pen for inspection at the same time.

Method used

A new energy vehicle charging interface insulation detection device is designed, including a megohmmeter and a positioning mechanism. The positioning mechanism consists of a connecting piece, a hanging rope, a positioning piece and a magnetic block. It is adsorbed on the car shell through the magnetic block, fixes the megohmmeter, and is detected through the connecting line and a detection pen.

Benefits of technology

This device allows the operator to detect the charging port by simply holding the detection pen, avoiding the inconvenience of holding the megohmmeter and the detection pen at the same time, and improving the convenience and accuracy of the detection.

Abstract

The utility model relates to the technical field of charging interface insulativity detection, and discloses a new energy automobile charging interface insulativity detection device which comprises a megohmmeter, a display screen is fixedly installed on the front side of the megohmmeter, and an adjusting knob is rotatably installed in the middle of the front side of the megohmmeter. The top of the front side of the megohmmeter is fixedly provided with three groups of connecting terminals which are distributed at equal intervals, and the top of the megohmmeter is provided with a positioning mechanism. According to the utility model, an operator attaches the positioning piece on the positioning mechanism to the automobile shell, so that the magnetic block in the middle of the positioning piece is firmly adsorbed on the automobile shell, the megohmmeter is firmly fixed on the column in cooperation with the lifting rope fixedly connected with the positioning piece, and then the operator holds the detection pen connected with one end of the first connecting line; and the charging port is continuously detected in all directions, so that the inconvenience that an operator holds a megohmmeter and a detection pen for detection at the same time is avoided, and the operator can measure the insulativity of the charging port more conveniently when using the megohmmeter.
