Abstract
The utility model relates to a circular pipe knife-shaped fusing core, which comprises a fusing sheet which is externally provided with an insulating sleeve; both ends of the insulating sleeve are fixedly provided with metal turnbuckles; the metal turnbuckles are screwed with compression nuts, the end surface of each of which is provided with a hole; both ends of the fusing sheet are connected with out-joining terminals; an insulating plate is arranged below the fusing sheet; the fusing sheet, the out-joining terminals and the insulating plate are connected together through screw bolt components; the out-joining terminals are provided with positioning plates; the external ends of the out-joining terminals extend out of the holes of the compression nuts. The utility model adopts the structures of the compression nuts and the positioning plates to form reliable connection; in addition, the fusing sheet, the out-joining terminals and the insulating plate are screwed, and thus, the contact is tighter so that good contact performance is provided. After the fusing sheet of the utility model is fused off, the compression nuts can be released, and the insulating plate can be taken out to replace the fusing sheet; therefore, the replacement of the fusing sheet is more convenient and quicker.
Description
Technical field
The utility model relates to a kind of fusing fuse, is meant a kind of pipe knife-edge fusing fuse of being convenient to change fuse piece especially.
Background technology
Existing pipe knife-edge fusing fuse generally can not be changed fuse piece, after fuse piece fusing, can only change whole fusing fuse, and existing fusing fuse also exists the problem of loose contact, therefore how can provide a kind of and can use repeatedly, fuse piece is easy to change and fuse piece and terminal between contact good fusing fuse, become pendulum at people's a difficult problem in front.
The utility model content
The purpose of this utility model is to provide a kind of pipe knife-edge fusing fuse, adopts insulation board, location-plate and clamping nut structure, can solve foregoing problems effectively.
The utility model purpose adopts following technical proposals to realize:
A kind of pipe knife-edge fusing fuse, include fuse piece, fuse piece is arranged with insulating case outward, and the insulating case two ends are installed with the metal swivel nut, is bolted with clamping nut on the metal swivel nut, the clamping nut end face is provided with the hole, the fuse piece two ends are connected with and pick out terminal, and fuse piece has insulation board, fuse piece, pick out between terminal and insulation board and link together by bolt assembly, pick out terminal and be provided with location-plate, pick out the terminal outer end and stretch out in outside the hole of clamping nut.
The utlity model has following advantage:
1. the utility model adopts clamping nut and location-plate structure, forms connection reliably, simultaneously, fuse piece, picks out between terminal and insulation board to being spirally connected, contact tightr, thereby excellent contact is provided.
2. the utility model adopts the clamping nut structure, after fuse piece fusing, clamping nut can be got loose, and takes out insulation board, changes fuse piece, and it is more convenient therefore to change fuse piece.
