Abstract:
A detent means for positioning a heat sink on the main body of a heat source, comprising an elastic member as a main portion thereof for pressing against said heat sink, two clamp holders are provided on two lateral sides of said elastic member; said elastic member is bent to render a bending area to be a force bearing point which is communicating in force with said two side clamp holders, said detent means is characterized by that:the thickness of a lateral arm between said bending area and one of said two side clamp holders is gradually reduced toward said side clamp holder; said lateral arm of said elastic member is slightly bent and fixed in shape by the force exerting on said elastic member, after being fixed in shape, an elastic force of said elastic member is fixed for firmly holding by clamping; said detent means prevents cracking of said main body of said heat source due to an overly large clamping force, and largely increases the extent of application of said detent means.
