MECHANICAL FUSE DEVICE

摘要

Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components.

主权项

1. A fuse device, comprising:
a body comprising at least one body portion; internal components within said fuse device, said internal components configured to change the state of said fuse device between a set state allowing current flow through the device and a triggered state which interrupts current flow through the device, wherein at least some of said internal components are at least partially surrounded by said at least one body portion; contact structures electrically connected to said internal components for connection to external circuitry; wherein said fuse device is configured such that when a threshold current level passes through said internal components, said body changes configuration in response to a generated electromagnetic field, which causes said device to transition to said triggered state.
