Abstract
Systems, apparatuses, and methods are described for thermal fuse circuit breakers. The thermal fuses described herein may be disposed in a connector, so that, should an overheating condition occur, for example, due to an arc discharge across or inside of the connector, the heat of the arc discharge melts a portion of the fuse, thereby preventing a potentially catastrophic event, such as fire, or damage to a component which may be more expensive than the thermal fuse itself.
Claims24
An apparatus comprising:
- a fusible conductor comprising a first end and a second end, wherein the fusible conductor is configured to, in response to a temperature of the first end or the second end increasing above a first threshold temperature, melt into a liquid;
- and
- a sheath surrounding the fusible conductor between the first end and the second end, wherein the sheath is configured to, in response to the temperature of the first end or the second end increasing above a second threshold temperature lower than the first threshold temperature, contract, thereby displacing the liquid.
An apparatus comprising:
- a housing;
- a pin or a socket, at least partially disposed within the housing, and having an exposed end configured to connect and disconnect with a complementary pin or a complementary socket of a second apparatus;
- a cable exiting the housing;
- a fusible conductor disposed within the housing and comprising a first end electrically connected to the pin or the socket, and a second end electrically connected to the cable, wherein the fusible conductor is configured to melt into a liquid when above a melting point temperature;
- and
- a sheath surrounding the fusible conductor between the first end and the second end, wherein the sheath is configured to contract when above a contraction temperature;
- wherein in response to heat conducted by the pin or the socket:
- the fusible conductor is configured to exceed the melting point temperature and melt into the liquid, and
- the sheath is configured to exceed the contraction temperature and contract, thereby displacing the liquid.
