Abstract
The fuse block assembly has a block which holds an element of substantially inverted U-shape. Co-operating projections and holes or recesses hold the element in position in the block. The ends of the legs of the element project out of the block to act as blade-type electrical terminals. The legs are joined to each other by a fusible portion which acts as the fuse. The plane of the terminals is transverse to the plane of the U. This configuration is stronger than a configuration in which the plane of the terminals lies in the plane of the U. It can be made by bending a flat strip into a U which is less wasteful of materials than cutting out the space between the legs.
Claims18
A fuse block assembly, comprising:
- an electrically insulating fuse block, and an electrically conductive fuse element receivable in the fuse block;
- said fuse element made of zinc and being substantially inverted U-shaped, having two legs, with each said leg comprising a blade-type terminal for electrical contact;
- said terminals having ends which extend out of the block through respective slots formed through a wall thereof, and said legs each having step means extending transversally of said legs constructed and arranged such that when said fuse element is in a position of use received in the block said step means engage an internal face of said wall internally of said block;
- the terminals being in two at least generally parallel planes which are at least generally transverse to a plane common to the legs of the U,;
- the terminals being connected to each other through a fusible portion of the fuse element which fusible portion is of reduced cross-section and the melting of which in use constitutes blowing of the fuse;
- and
- said fuse element and said block being provided with cooperating engagement means which act to hold them together in said position of use.
