Abstract
The utility model relates to an insert type fuse structure which comprises an upper cover plate, a casing, a conducting strip, a luminous display assembly, a fuse and a connecting wire. A storage chamber is arranged in the centre of the upper part of the casing. The conducting strip is connected with the fuse and the connecting wire is connected with the luminous display assembly, which are embedded in the storage chamber to form the insulation protection. A plug board which is arranged under the conducting strip can be plugged on a connecting socket board. When the fuse is not broken, the luminous display assembly does not brighten because the current on the connecting wire is too small. If the current is big, which generates high temperature and causes the fuse to be over load and not capable of bearing, the fuse is melted and broken, and the current of the luminous display assembly is enlarged to create a luminous display phenomenon, display and safe protection efficiency. A pair of L-shaped notches which are arranged at inner side of the upper part of the conducting strip makes the connecting wire completely closed on the L-shaped notch with thickness of the conducting strip to form a two-side contacted welding mode and sufficiently solve the problem that the existing spot welding mode is easy to oxygenize and strip after a long time.
