Problems solved by technology

The development of fast charging technology makes the charging faster and faster, but due to the thickening of the cable and the power terminal of the charging gun, the plugging force of the charging gun head is also increasing. At present, it is difficult to operate with both hands. The 50A DC charging gun is used as the For example, the maximum overall insertion force is 25KG, and the maximum insertion force of the DC terminal is 10.2KG. Therefore, reducing the insertion force of the charging gun is an urgent problem to be solved in the fast charging technology

Abstract

The present invention discloses a power supply terminal and a charging gun head. The power supply terminal comprises a hollow arranged terminal expand tube, a terminal core rod axially mounted in theterminal expand tube, an insulation head fixedly installed at the end portion of the terminal core rod and an elastic piece fixed between the terminal core rod and the terminal expand tube. The powersupply terminal comprises a first state when the elastic piece is compressed and a second state when the elastic is in normal state, and the length of the terminal core rod stretching into the terminal expand tube in the first state is larger than the length of the terminal core rod stretching into the terminal expand tube in the second state. The power supply terminal is arranged to reduce the plugging force of the charging gun head and relieve the labor intensity when plugging is performed; the terminal expand tube can reduce the friction prior to expansion of the terminal expand tube; and the terminal expand tube can ensure the contact pressure after the expansion of the terminal expand tube so as to ensure the heavy current conduction current effect.

Description

technical field [0001] The invention relates to the technical field of electric tool charging equipment, in particular to a power terminal and a charging gun head. Background technique [0002] With the rapid development of electric vehicles, electric vehicles are rapidly popularizing, and fast charging of electric vehicles has become the focus of the development of the automobile industry and the energy industry. The development of fast charging technology makes the charging faster and faster, but due to the thickening of the cable and the power terminal of the charging gun, the plugging force of the charging gun head is also increasing. At present, it is difficult to operate with both hands. The 50A DC charging gun is used as the For example, the maximum overall insertion force is 25KG, and the maximum insertion force of the DC terminal is 10.2KG. Therefore, reducing the insertion force of the charging gun is an urgent problem to be solved in the fast charging technology. ...
