Elastic assembly, heat dissipation device, electronic equipment, circuit module and assembly method thereof

The invention relates to the technical field of communication, and discloses a non-loosening elastic assembly, a heat dissipation device, electronic equipment, a circuit module and an assembly method thereof. After a connecting part and a fastening part in the non-disengagement elastic assembly are installed, an anti-disengagement distance used for preventing the second component from being disengaged from the first component can be formed through a nail body in the connecting part, an elastic element and an anti-disengagement component. Secondly, a fixed distance used for fixing the second component to the third component can be formed through the nail body in the connecting component and the fastening component, and finally, a fixed distance used for elastically combining the first component to the second component can be formed through the nail body in the connecting component, the elastic element and the fastening component. And the first component is elastically combined with the elastic distance of the
