1. A fuse holder of the pressure type construction for use with fuses of varying amp capacity with heat being generated in the fuse holder in service which is required to be dissipated, which comprises a support, a pair of longitudinally spaced pressure connector blocks secured to said support, a generally small size fuse disposed in the space between the connector blocks and having tangs projecting from opposite ends and overlying the connector blocks, means extending through the tangs and into the connector blocks to secure the tangs to the connector blocks, at least one opening at the outer ends of the connector blocks disposed to receive electric wires to complete a circuit through the connectors and fuse, means securing the wires in place against the inside walls of the respective connectors, and at least one fin integrally formed with each connector block and projecting upwardly from each connector block at a location between a respective tang and the respective means securing a wire to a connector block to thereby dissipate heat from the metal area of each connector block between the fuse and the wire connections, said fin being approximately one-sixteenth of an inch in width and of a height to project to a horizontal plane extending vertically outwardly from a horizontal plane extending through the horizontal center line of the fuse and extending completely across the width of the connector block.
