Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, in particular to a charging pile input power supply plug kit and a charging pile. Background Art

[0002] When the existing charging pile is connected to an external power source, a junction box is usually left, and a junction board is provided in the junction box to facilitate the installer to connect the external power line. However, one end of the junction board is usually connected to the wiring terminal inside the charging pile, and the wiring terminal is usually fixed to the power line of the circuit board inside the charging pile when leaving the factory. In this way, when the installer is debugging and installing, he needs to hold the junction board with one hand and pull the power line and the connection and locking tools with the other hand. However, since the junction board cannot be completely separated from the charging pile, in the process of connecting the power line, due to the limitations of the installation site and the location of the junction board, there may be problems of inconvenience in connection, and the problem of accidentally pulling the junction board down by using the force may occur, which leads to the need to reconnect the charging pile and the internal power line, and when the external power line and the junction board are connected, it is also necessary to use soldering and other methods to fix the external power line to the junction board. When it is necessary to perform equipment maintenance or replace the power line, the inconvenience caused by this connection method is particularly prominent. Not only does it require professional tools, but the operation is complicated. If you are not careful, you may damage the pins or power lines, which brings additional troubles to the maintenance work. At the same time, frequent welding and disassembly may also affect the contact performance between the pins and the power cord, further reducing the stability and safety of the charging pile.
