Offering radial crack in the middle part of plate, the lower end inserted into gap of fuse and electrode contact, when fuse is extracted
Time crack closure.When being separated with plug bottom on plug top, electrode can be sealed up for safekeeping by insulation barrier, it is to avoid
Electrode exposes in atmosphere, and changing fuse when, electrode is charged, and insulation barrier can improve plug
The security performance of bottom.
Described plug top is elbow, and including the vertical section with the grafting of plug bottom, vertical section offers cavity,
Fuse is arranged in cavity, and vertical intrasegmental part is fixed with the snap ring for clamping fuse, and vertical section is connected with
Horizontal segment, is provided with extinguishing arc and inserts electric pole in described horizontal segment, extinguishing arc insertion electric pole is fixing with snap ring to be connected,
Horizontal segment offers and inserts the conical cavity that electric pole is coaxial, conical cavity and extinguishing arc insertion electric pole for even with extinguishing arc
Connect the casing joint on equipment.Plug top uses elbow, and the cable that plug bottom connects avoids straight down
Cable bending, reduces the moment of flexure that plug is subject to.The horizontal segment on plug top is telescopic joint with equipment, grafting
Convenient.
This utility model compared with prior art, has the advantage that
The cable plug with self-protection function carries fuse, does not the most install fuse, subtract in equipment
The little volume of equipment, solves the problem that legacy equipment line cannot install protection fuse.Plug top
It is the security performance that insulation setting improves plug with plug bottom.Fuse in plug can be changed, more
Fuse and the grafting of plug top when changing fuse, plug top is not charged, it is not necessary to level power supply in cut-out
It is replaced, improves the security performance changing fuse.
