Fuse Element with Trigger Assistance
First Claim
Patent Images
1. A discrete fuse element for protecting a current consumer, comprising:
- a first terminal point;
a second terminal point;
a fusible material, which melts at a predetermined temperature, between the first and the second terminal points, which is configured to establish, in the non-molten state, an electrically conductive connection between the first and the second terminal points; and
an assisting means between the first and the second terminal points, configured to assist in removing the fusible material in the molten state from an area between the first and the second terminal points, wherein the fusible material is deposited on a surface of a carrier, and the assisting means includes the surface of the carrier which exhibits a property of repelling the fusible material.

Abstract
A current consumer and/or an electric device generates a predetermined amount of heat in the event of a malfunction. The electric device is protected from overheating in that it is arranged, with a fuse in a circuit, such that the fuse and the electric device are thermally coupled to one another, so that the generation of the amount of heat by the electric device causes a fusible material in the fuse to melt. In this manner, the current terminal path of the electric device is interrupted.

20. A discrete fuse element for protecting a current consumer, comprising:
-
a first terminal point;
a second terminal point;
a fusible material, which melts at a predetermined temperature, between the first and the second terminal points, which is configured to establish, in the non-molten state, an electrically conductive connection between the first and the second terminal points; and
an assisting means between the first and the second terminal points, configured to assist in removing the fusible material in the molten state from an area between the first and the second terminal points, wherein the fusible material is deposited on a surface of a carrier, and the assisting means includes the surface of the carrier which exhibits a property of repelling the fusible material, wherein the assisting means comprises an assistance material which is in contact with the fusible material and reduces a viscosity of the fusible material once the fusible material has melted, and wherein the assisting means comprises a flux arranged on the fusible material of the fuse, the flux being embodied such that a flowing-off of the fusible material in the molten state is accelerated.
