Abstract
An improved fuse and mounting arrangement is disclosed especially suited for mounting on a printed circuit board or the like. The fuse device itself is of the two-bladed type for reinserting in an individual fuse holder. The holder is formed of a thermo setting plastic with a high resistance to heat. End positioned cavities in the holder are dimensioned to receive conductive terminals which accommodate the fuse blades and which holder further includes leg portions extending downwardly for appropriate attachment to the associated printed circuit board, such as by soldering or the like.
Claims5
An improved miniature fuse device and mounting arrangement adapted for use on a printed circuit board, comprising on combination:
- a holder of rigid, non-conductive material having cavities at respective ends thereof each being open at its respective top, bottom and end sidewall, said holder further having an arm within each of said cavities extending laterally to a position adjacent its respective open end sidewall;
- first and second end terminals of conductor material which are each slid through a respective one of said open end sidewalls and around a respective one of said lateral arms for retention in the interior of said holder on said laterally extending arms in said respective cavities, said end terminals having leg portions extending through said open bottom for mounting to the printed circuit board;
- and
- a fuse block of transmparent non-conductive material having a pair of spaced apart partially embedded blades extending downwardly therefrom together with a fuse link of the desired current carrying capacity electrically bridged across said blades within said fuse block,
- said blades being adapted for releasably inserting into and being retained by friction fit within said respective end terminals in said fuse holder.
A fuse holder especially adapted for mounting on a printed circuit board and accommodate a blade fuse device, comprising in combination:
- a holder body of rigid, non-conductive material having cavities at respective ends thereof each being open at its respective top, bottom and end sidewall, said holder further having an arm member within each of said cavities extending laterally to a position adjacent its respective open end sidewall;
- first and second end terminals of conductive material which are each slid through a respective one of said open end sidewalls and around a respective one of said lateral arms for retention in the interior of said holder on said laterally extending arm members in said respective cavities and adapted to operatively receive the blade fuse device,
- said end terminals including angled leg portions extending downwardly thru said open bottom for attachment to the associated printed circuit board.
