Abstract
An electrical component is installed in a plastic cup. The component has two electrical connecting lines, and a parting location that is bridged by a solder metal is arranged in one lead. In addition, a prestressed spring is arranged at the one lead for removing the lead from the parting location during melting of the solder metal as a result of an overload, so that the component is disconnected from a current source. The one lead is pinched to a thickness of 0.2-0.5 mm.
Claims8
An electrical component being installed in a plastic cup, said component comprising:
- at least a first lead wire and a second lead wire;
- the first lead wire serving as a first terminal lead;
- the second lead wire being formed by two portions with a first portion being directly connected to the component;
- a second terminal lead being formed by two portions with a first portion of said second terminal lead being directly connected to the component and being formed by said first portion of said second lead wire, the second portion of said second terminal lead being formed by a separate lead wire, said separate lead wire being flattened to a thickness of 0.2 mm to 0.5 mm;
- the first and second portions of said second terminal lead having ends abutting each other at a parting location;
- a fuse being formed by solder metal bridging the parting location to electrically connect the first and second portions together;
- and
- a separate prestressed spring engaging an end of one of the first and second portions of said second terminal lead so that with a melting of the fuse material, the spring will urge the one portion away from the parting location to interrupt a current flow between the first and second portions.
An electrical component being installed in a plastic cup, said component having at least two terminal leads disposed in the cup, one of the two leads being formed by two portions having ends abutting each other at a parting location, a fuse formed by solder metal bridging the parting location to electrically connect the portions together, said one lead being flattened to a thickness of 0.2 mm to 0.5 mm, a separate prestressed spring engaging an end of one of the two portions of the one terminal lead so that with a melting of the fuse material, the spring will urge the one portion laterally away from the parting location to interrupt a current flow between the two portions.
