Abstract:
1. A clamping device for a DIN rail, adapted to be fixed on a DIN rail having a first slide rail and a second slide rail, the clamping device comprising: a base comprising at least one first buckling component, a receiving recess, and at least one base positioning component, wherein the at least one first buckling component is buckled on the first slide rail; an elastic element, allocated in the receiving recess; a positioning blade spring, having a spring positioning component, and fixed on the base, and a sliding element, having an inward depressed component, wherein a support component and a positioning hole are provided at a bottom surface of the depressed component, a first positioning component and a second positioning component are provided at the positioning hole, the depressed component is provided with at least one second buckling component and at least one fitting component externally, the at least one fitting component having a slide groove, and the at least one second buckling component is buckled to the second slide rail; wherein when the sliding element is positioned on the base, the at least one fitting component is positioned corresponding to the at least one base positioning component, the spring positioning component is positioned corresponding to the second positioning component, the elastic element bears against the support component to produce a clamping force, the sliding element slides relative to the base through the slide groove, and when the sliding element slides relative to the base, the spring positioning component moves from the second positioning component to the first positioning component for being positioned.
