Abstract

The invention provides an electric appliance box and an air conditioner provided with the same. The electric appliance box comprises a box body and a PCB, wherein the edge of the first side of the PCB cooperates with the box body through a clamping structure, the second side, which is opposite to the first side, of the PCB and the box body are provided with a fixed connection structure, and the clamping structure has an activity allowance in the direction from the first side to the second side. Through the clamping structure, deformation space can be provided for the PCB, the deformation of the PCB is reduced, and the safety of the electric appliance box is guaranteed.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an electrical box and an air conditioner with the electrical box. Background technique [0002] There are more and more SMD components in the existing controllers, and the integration density of the devices is also increasing. Once the SMD area is subjected to impact or external force (such as plug-in terminals), it is very easy to cause PCB deformation, which will cause greater stress on the SMD device, and even crack the SMD pins, resulting in circuit failure and the entire controller cannot work. . [0003] Taking the widely used split inverter outdoor unit controller as an example, the PCB board adopts an upside-down layout (the position of the main patch device is placed upside down). In order to ensure the reliability of PCB fixing, combined with the characteristics of the electrical box structure, The solution of middle and surrounding support, four corners and ...
