Description

Electric shock prevention electrical interface connecting device

Technical Field

Background

In a charging inlet, i.e., a connection device between a charging cord and a vehicle-mounted power supply, which is commonly used in vehicles such as electric bicycles and mopeds, a connection end with a protruding terminal is generally referred to as a "male end", and a connection end with a slot is generally referred to as a "female end". The pin terminals of the male end connector are difficult to prevent from being communicated with each other by external objects, for example, once the fingers of a person communicate with the pin terminals, when one of the pin terminals is connected with the positive pole of a power supply and the other pin terminal is connected with the negative pole of the power supply, the electric shock of a human body can be caused. Once the voltage and current of the power supply are too large, personal injury and even life danger are easily caused, and similar accidents are reported by news for many times.
