The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a bar fuse formula isolator, includes isolator main part and generating line row, the bottom surface fixed mounting of isolator main part has a plurality of evenly distributed's cross-over connection copper bar, the generating line arrange set up in the bottom surface of isolator main part and with the cross-over connection copper bar electricity is connected, just the generating line arrange with it is fixed to lock through special-shaped screw between the isolator main part.
Furthermore, the top of special-shaped screw is provided with a straight groove, the bottom of special-shaped screw is provided with rectangular shape latch segment, be provided with in the generating line row with latch segment lock connects fixed locking groove, just the top in locking groove is provided with rectangular shape opening.
Furthermore, a plurality of through holes communicated with the top ends of the special-shaped screws are formed in the top surface of the isolating switch main body.
Furthermore, one end of the bridging copper bar is fixedly installed in the isolating switch main body through a screw, and the other end of the bridging copper bar is electrically connected with the switch element in the isolating switch main body.
The utility model has the advantages that:
the strip fuse type isolating switch is more convenient to install, and the torsion of the special-shaped screw is increased geometrically, so that the switch can be more firmly installed; meanwhile, the jumper copper bars on the bottom surface of the switch are tightly attached to the bus bar, so that the contact area between the isolating switch and the bus bar is larger, and the overcurrent is safer.

Detailed Description
In order to make the utility model realize the technical means, creation characteristics, achievement purpose and efficiency are easy to understand and understand, the utility model is further explained by combining the detailed implementation mode.
As shown in fig. 1-3, a bar fuse formula isolator, including isolator main part 1 and generating line row 4, isolator main part 1's bottom surface fixed mounting has a plurality of evenly distributed's cross-over connection copper bar 2, generating line row 4 set up in isolator main part 1's bottom surface and with the 2 electricity of cross-over connection copper bar are connected, just generating line row 4 with it is fixed to lock through special-shaped screw 3 between the isolator main part 1.
The top end of the special-shaped screw 3 is provided with a straight groove, the bottom end of the special-shaped screw 3 is provided with a long-strip-shaped locking block, the busbar 4 is internally provided with a locking groove fixedly locked with the locking block, and the top end of the locking groove is provided with a long-strip-shaped opening; when isolator main part 1 is connected with generating line row 4, rotatory special-shaped screw 3 adjust rectangular shape latch segment into with rectangular shape opening parallel and level state, thereby conveniently slide into the locking groove with rectangular shape latch segment through rectangular shape opening, later rotatory special-shaped screw 3, can drive rectangular shape latch segment at the locking groove internal rotation, make rectangular shape latch segment locking in the locking groove fixed, and then make locking fixed between special-shaped screw 3 and the generating line row 4.
The top surface of isolator main part 1 is provided with a plurality of through-holes with 3 top intercommunications of special-shaped screw, conveniently extends the in-line inslot of grafting to 3 top surfaces of special-shaped screw with instruments such as a word screwdriver through the through-hole to drive the rotation of special-shaped screw 3.
