  • Mechanism of fastening detachable electronic device to DIN rail
    Patent number: 8062061
    Abstract: A fastening mechanism for fastening a detachable electronic device onto a DIN rail includes a frame, a first slab member and a first resilient element. The frame includes a base, a first extension part and a second extension part. The first extension part and the second extension part are arranged at bilateral sides of the base. A first perforation is formed between the first extension part and the base. The first slab member is movable along the bottom surface of the first extension part and has an end penetrating through the first perforation to be disposed over the base. The first resilient element is coupled to the first slab member and exerts a clamping force for claming a first extending edge of the DIN rail between the first slab member and the base.
