Housed resistor

Claim 1

An electrical resistor, comprising an open-top metal casing including a bottom wall a pair of sidewalls and a pair of end walls, said end walls and sidewalls being connected integrally to the bottom wall and each end wall including a pair of end sections, one side edge of each end section being integrally connected to the corresponding sidewall and the other side edge of each end section disposed in abutting relation with a side edge of the adjacent end section to provide an unconnected joint between said end sections at each end of the resistor, a mounting tab integrally connected to each end of the bottom wall and extending outwardly therefrom beneath said end walls, an insulating material disposed within the casing, and substantially filling the casing, a resistance element embedded within the insulating material, terminal means connected to the resistance element and projecting outwardly of said insulating material in a position to be attached to electrical leads, and means projecting inwardly of the casing and engaged with the insulating material to prevent free removal of said insulating material from the casing.
