==ACTIVE/PASSIVE FUSE MODULE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240021394 titled 'ACTIVE/PASSIVE FUSE MODULE

==Simplified Explanation==

The patent application describes an active/passive fuse module that includes a fuse with an electrically insulating fuse body, endcaps on opposing ends, a fusible element extending through the fuse body, and an arc quenching material surrounding the fusible element. The module also includes a pyrotechnic interrupter (PI) coupled to the fuse body, which consists of a housing, a shaft, a piston within the shaft, a drive pin extending from the piston into the fuse body, a cutter adjacent to the fusible element, and a pyrotechnic ignitor above the piston. When the pyrotechnic ignitor receives an initiation signal, the piston and drive pin are forcefully driven through the shaft, causing the cutter to separate the fusible element.

* The patent application describes an active/passive fuse module that includes a fuse with an insulating body, endcaps, a fusible element, and an arc quenching material.
* The module also includes a pyrotechnic interrupter (PI) that is connected to the fuse body.
* The PI consists of a housing, a shaft, a piston, a drive pin, a cutter, and a pyrotechnic ignitor.
* When the pyrotechnic ignitor receives a signal, the piston and drive pin are driven through the shaft, causing the cutter to separate the fusible element.

Potential applications of this technology:

* Electrical power distribution systems
* Circuit protection in electronic devices
* Industrial machinery and equipment
* Automotive industry

Problems solved by this technology:

* Preventing electrical faults from causing damage to equipment or systems
* Ensuring safe operation by interrupting excessive current flow
* Protecting sensitive electronic components from overcurrent conditions

Benefits of this technology:

* Improved safety by quickly interrupting excessive current flow
* Enhanced reliability of electrical systems and equipment
* Cost-effective solution for circuit protection
* Easy installation and maintenance


==Original Abstract Submitted==

an active/passive fuse module including a fuse having an electrically insulating fuse body, first and second endcaps disposed on opposing ends of the fuse body, a fusible element extending through the fuse body between the first endcap and the second endcap, and an arc quenching material disposed within the fuse body and surrounding the fusible element. the fuse module further includes a pyrotechnic interrupter (pi) coupled to the fuse body, the pi having a housing defining a shaft, a piston disposed within the shaft, a drive pin extending from the piston into the fuse body, the drive pin terminating in a cutter disposed adjacent the fusible element, and a pyrotechnic ignitor disposed within the shaft above the piston configured to detonate upon receiving an initiation signal from a controller, whereby the piston and the drive pin are forcibly driven through the shaft causing the cutter to separate the fusible element.
