Abstract

Abstract In a preferred form, this disclosure relates to an electrical connector means comprising a female terminal housed within a female insulator body and a male terminal housed within a male insulator body. The female terminal has a forward portion provided with a tapered entry section and a spherical socket section. The male terminal has the forward portion comprising a pair of spaced arms having hemispherical sections at their forward end which together define a spherical forward end section. The male terminal is connectable to the female terminal by inserting the same therein until its spherical end section seats within the spherical section of the female terminal. The mating parts provide a large contact area and mechanically interlock the male and female terminals and the male and female insulator bodies together.
