Thermal fuse
First Claim
1. A thermal fuse for use in interconnection of lead acid batteries and adapted to fuse as a result of heat being conducted through said fuse from the batteries or other devices to which it is attached, rather than as a result of direct heating of the fuse consequent on the current carried by said fuse, said fuse comprising:
- a pair of mounting plates for permitting current to serially flow therethrough to devices to which they are attached, anda heat meltable electric current conducting material disposed in its solid form between the mounting plates and providing a flow path for electric current between the mounting plates, said heat meltable electric current conducting material connecting with a member which will remain unmelted at the temperature at which the heat meltable electric current conducting material melts, said member being of sufficient dimensions so that when the heat meltable electric current conducting material melts it will fall by gravity from between the mounting plates and draw substantially all of the heat melted material with it.

Abstract
A thermal fuse for use in interconnection of lead acid batteries which will fuse as a result of heat being conducted through the fuse from the batteries or other devices to which it is attached, rather than as a result of direct heating of the fuse consequent on the current carried by the fuse. The fuse has a pair of mounting plates connected to terminals of the fuse with a heat meltable electric current conducting material in solid form disposed between the plates to provide a flow path for electric current. A member is also disposed between the plates connecting with the solidified heat meltable material and of sufficient mass so that when the material melts, the member draws substantially all of the material with it as it falls due to gravity from between the mounting plates.
