Mechanical fuse, how to connect a neck cord, and a mechanical fuse on the neck cord with a mechanical fuse

摘要

This invention stipulates the mechanical fuse 20 regarding neck cord/code 30. In order the draw bar pull element in specified direction 70, for the explosion element 50 which is included in the above-mentioned mechanical fuse to break, when exceeding the specified fuse power which is designed, it puts the mechanical fuse, in a state where the above-mentioned neck cord/code is opened. The explosion element has destructive plane surface 51. In destructive plane surface, when the pressure in the above-mentioned destructive plane surface the above-mentioned draw bar pull element brings the fact that it exceeds the value which is decided by the above-mentioned fuse power, damage happens. As for the mechanical fuse furthermore, in order to induce the element of the above-mentioned draw bar pull in the above-mentioned specified direction 70 to the above-mentioned destructive plane surface the frame it possesses 60 which is formed, 61 and 62. On the one hand, transfer of the power element which has another direction is controlled.
