Touch heat insulation pcb board

Abstract

This application relates to the technical field of PCB boards, in particular to point-contact heat-insulating PCB boards, including a PCB board body, and a plurality of downwardly protruding bosses are uniformly arranged around the PCB board body, and the downward protrusions of the bosses are The cross-sectional area gradually decreases, and the middle part of the PCB board body is provided with a downwardly protruding installation top seat, and the height of the protrusion is higher than that of the installation top seat, and the installation top seat is set There are installation through holes that go up and down. For the point-contact heat-insulating PCB board provided by this application, due to the height difference between the convex column and the installation top seat, the middle part of the PCB board will be slightly concave when it is locked, and the elasticity of the PCB board itself acts as a preload. Effect: In addition, the downward cross-sectional area of ​​the convex column gradually decreases, which greatly reduces the contact area of ​​the heat conduction surface on the premise of ensuring the support strength, reduces the heat conduction speed, and enhances the heat insulation effect.

Description

【Technical field】 [0001] The application relates to the technical field of PCB boards, in particular to point-contact heat-insulating PCB boards. 【Background technique】 [0002] If the PCB board works in a high-temperature environment for a long time, not only the working efficiency of the electrical components cannot be guaranteed, but also the life of the circuit and electrical components will be shortened, especially on home appliances such as disinfection cabinets, ovens, range hoods, etc. Due to the existence of a large heat source during work, certain isolation measures need to be taken, and the current measures are mainly to isolate the PCB board from the installation part of the home appliance by adding sheet metal heat shields and using multiple plastic terminals. , When assembling, use the two ends of the plastic terminal to connect the installation holes on the PCB board and the installation holes on the installation part of the home appliance respectively, which ...

[0002] If the PCB board works in a high-temperature environment for a long time, not only the working efficiency of the electrical components cannot be guaranteed, but also the life of the circuit and electrical components will be shortened, especially on home appliances such as disinfection cabinets, ovens, range hoods, etc. Due to the existence of a large heat source during work, certain isolation measures need to be taken, and the current measures are mainly to isolate the PCB board from the installation part of the home appliance by adding sheet metal heat shields and using multiple plastic terminals. , When assembling, use the two ends of the plastic terminal to connect the mounting holes on the PCB board and the mounting holes on the installation part of the home appliance respectively. The operation is cumbersome and the heat insulation effect is not good.
