摘要： Electrical switching devices that can have a housing cup having an opening and a header covering and making a seal with said cup. Internal components are included within the housing, with the internal components configured to change the state of the switching device from a closed state and an open state in response to input. The closed state allows current flow through said device and the open state interrupts current flow through said device. A plurality of fixed contact are included that are electrically connected to said internal components for connection to external circuitry, wherein the the fixed contact pass though the header with a portion exposed above the header. A plurality of glass/ceramic eyelets are included, each of which is mounted to a respective one of the fixed contacts on the exposed portion of its one of the fixed contacts. Each of the eyelets can be radially symmetric about its one of the fixed contacts, with the eyelets covering less than all of the header.

摘要： Fuse devices and electrical systems using the fuse devices are disclosed, with the fuse devices having internal components to cause a fuse blown event when the pre-determined current level is reached through the contacts. The internal components can comprise a levitation actuator that causes separation between one or more of the contacts as the current level approaches the predetermined level. This causes contact levitation and arcing, which increases the resistance at the contact being separated. This in turn causes the current through the contacts to seek another path that in the embodiments herein is a path to a pyro feature. The current activates the pyro feature, which causes the contacts to separate and puts the fuse device in “fuse blown” condition where currents can no longer flow through the contacts.

摘要： Disclosed herein are passive triggering mechanisms for activation of pyrotechnic features within electrical switching devices, such as contactor devices and fuse devices. The activation of the pyrotechnic features is configured to change the configuration of the internal components of the switching device and prevent current flow through the device. In some embodiments, the triggering mechanisms comprise features that respond to a magnetic field, such as a reed switch. In some embodiments, threshold strength of a magnetic field needed to trigger the passive triggering mechanism, which corresponds to a threshold level of current running through the switching devices indicating a dangerous overcurrent, can be adjusted based upon the distance between the passive triggering mechanism and a portion of the device such as a power terminal or feature connected to a power terminal.

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.
