Problems solved by technology
Since there are many different lines that need to be connected, it is necessary to judge each wire when connecting, and it is easy for the installer to make a wrong connection, causing the air conditioner to leave a safety hazard
The wire wiring inside the shell is too messy, which will cause inconvenience to the maintenance personnel during maintenance

The invention relates to a control box structure of an air conditioner indoor unit, comprising an outer shell, a printed circuit board, a control box cover and a binding post. The outer shell forms a hollow internal space for accommodating and protecting the printed circuit board; the printed circuit board forms a component for controlling the operation of an air conditioner by integrated elements and lines; the control box cover is fixedly combined with the outer shell and covers the outer shell to form the appearance of the control box; and the binding post is connected with each component of the air conditioner by leads and is used for transmitting control signals of the printed circuit board, an insertion assembly is arranged in the outer shell, a communication insertion assembly in the control box structure and a circuit wire of the binding post are connected in advance, and the printed circuit board is connected with the insertion assembly by a plug of the printed circuit board. In the invention, the direct lead connection between the printed circuit board and the binding post does not need to be considered, thus the situation of the error connection of leads in the process of assembling the printed circuit board can be avoided, various connecting lines in the control box are more order, and the possibility of short circuit due to too disordered leads is reduced.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a plug-in connector provided on the casing for connecting plugs on a printed circuit board, and the circuit between the plug-in plug and the terminal is pre-connected inside the casing, so that only the The control box structure of the indoor unit of the air conditioner installed on the printed circuit board can be completed by plugging the plug. Background technique [0002] An air conditioner is an indoor climate control device, and its main components include a refrigeration cycle system including a compressor, a condenser, a throttling device, and an evaporator, and an air cycle system including a blower, an air duct, and an air inlet and outlet. The air conditioner absorbs indoor air, changes its temperature through the evaporator and condenser of the heat exchange device, and then discharges it back into the room to realize the functions of cooling or heati...
