NV-41 mine

From Wikipedia, the free encyclopedia

The NV-41 was a wooden cased Soviet anti-tank blast mine used during the Second World War. The mine consists of a square wooden box with a filling plug on the bottom. The top of the box is covered by a thin pressure lid, which covers a pressure plate held up by a spring. Sufficient pressure on the lid collapses it down onto the pressure plate. Downward movement of the pressure plate moves down a pressure plunger, which in turn levers up the striker retaining lever, releasing the spring loaded striker and allowing it to impact the stab sensitive detonator, triggering the main charge.

The mine has a central tube in the bottom, which can either accept an electric command detonator or a wire, which is attached to the pressure plunger. The wire can anchored, allowing it to act as an anti-handling device.
