Anti-drop plug for electric vehicle charger

Abstract

The invention discloses an anti-drop plug for an electric vehicle charger, which comprises a panel, an installation shell, installation columns, contact blocks, torsion springs and a socket with an insertion sheet and an insulation head, wherein the installation shell is fixedly connected to the panel; four installation columns are fixed in the installation shell; a contact block and a torsion spring are inserted into each installation column; one end of each torsion spring is clamped on the corresponding contact block, the other end of each torsion spring is clamped on the inner wall of the installation shell, and the two contact blocks form an electric contact body; the panel is provided with two plugging grooves, and the two plugging grooves are correspondingly disposed at the rear sides of the two electric contact bodies. The plug disclosed in the invention is simple in structure, the plug can be effectively prevented from falling off from the jack, the structure is simple, realization is easy, and the use effect is good. The plug provided by the invention can ensure the fastening force, avoids the phenomenon that the power plug of the electro-tricycle falls off due to jolt, and is good in use effect.

Description

Technical field: [0001] The invention relates to a fall-off prevention plug for an electric vehicle charger. Background technique: [0002] The electric tricycle is a three-wheeled transport vehicle powered by a battery and driven by a motor to pull goods or people. The electric tricycle adopts a tubular large-capacity, left and right lining, deep discharge, traction battery, which can adapt to continuous discharge for a long time The requirements of the battery, the normal use of the battery for two years, the internal capacity does not decrease. [0003] When electric tricycles are in use, in order to facilitate charging, paid charging piles are often set up in the parking area. The plugs in the charging piles are compatible with the jacks in the electric vehicles. When charging for a fee, people often park the car directly in the charging area and then leave. After charging is complete, come back to pick up the car. The plug of the charging pile has a high usage rate, a...

AI Technical Summary

Problems solved by technology

The plug of the charging pile has a high usage rate, and it will wear out after a long time and cause the size to become smaller. Therefore, after a long time of use, the plug will fall off. If it falls off when people leave, it will delay the travel plan and affect the use.
