It relates to an LP fuse fixed terminal for a vehicle that is prevented from being broken or separated.

In general, the LP fuse is a type of mini fuse for cost reduction, and is manufactured in a smaller size than a conventional fuse, and in particular, the upper and lower heights are small. The LP fuse has a protrusion protruding from the center of the lower end of the body to be inserted into the fuse box, and electrode terminals made of conductive metal are formed at both ends of the protrusion.

The fuse box is electrically connected to both electrode terminals and is provided with a fixed terminal having a fixing force so that the inserted LP fuse does not come off.

The fixed terminals used in such fuse boxes need to be easily inserted because many LLP fuses are inserted and fixed in the fuse box and can be replaced several times during the life of the vehicle. Even if there is, it must have sufficient fixing force to prevent the separation of the LP fuse.

However, the fixed terminal according to the prior art does not have a strong fixing force, and thus the LP terminal is easily separated by vibration generated during use of the vehicle. In other words, the LP fuse is fixed only by the pressing force of the elastic piece that fixes the electrode terminal, and this elastic piece is a cantilever shape that is formed long from the body part toward the top, so the fixing force is greatly affected by the vibration, so that the LP terminal is separated from the fixed terminal. There will always be serious problems.
