Utility model content
To this, the purpose of this utility model is to provide a kind of isolating switch fuse group being suitable for big current and passing through.
The technical scheme realizing the utility model object is:
A kind of isolating switch fuse group, comprises pedestal, the fuse be arranged on pedestal, the moving contact be removably set in described pedestal, and the first fixed contact being suitable for being connected with described moving contact be located on described pedestal and the second fixed contact; One end of described fuse is connected with one end of conductive plate, the other end of described conductive plate has the flat link being suitable for being connected with external flat terminals, described first fixed contact is connected with the other end of described fuse away from one end of described moving contact, and described second fixed contact is provided with external terminal away from one end of described moving contact; Described first fixed contact and described second fixed contact are all by two pieces of superimposed two structure of contact terminals formed of metallic plate, it have two contact part being suitable for being connected with described moving contact.
In technique scheme, the flat link of described conductive plate and the external terminal of described second fixed contact are provided with screw hole.
In technique scheme, two metallic plates in described first fixed contact and described second fixed contact are fixed together by welding or riveting.
In technique scheme, described pedestal upper end forms and is suitable for described conductive plate and spacing the first stopper slot being beneficial to be in place of described first fixed contact.
In technique scheme, the lower end of described pedestal forms and is suitable for spacing the second stopper slot being beneficial to be in place of described second fixed contact.
In technique scheme, described base outer wall is provided with radiating groove with described first fixed contact and described second fixed contact correspondence position.
The utility model has positive effect:
(1) in isolating switch fuse group of the present utility model, described first fixed contact and described second fixed contact are all by two pieces of superimposed two structure of contact terminals formed of metallic plate, it have two contact part being suitable for being connected with described moving contact, so, there is when fixed contact contacts with moving contact larger contact-making surface, thus big current can be suitable for pass through.
(2) in isolating switch fuse group of the present utility model, by arranging the first stopper slot and the second stopper slot, can more be beneficial to related components when completed knocked down products and being in place, thus increasing work efficiency, and ensureing product quality.
(3) in isolating switch fuse group of the present utility model, by arranging radiating groove with described first fixed contact and the second fixed contact correspondence position on pedestal, such setting, can air circulation be beneficial to thus accelerate the heat loss on the first fixed contact and the second fixed contact when isolating switch works, reducing temperature rise.
