ABSTRACT:
An electrical female terminal of two piece construction comprising a base terminal and a spring member. The base terminal is stamped and formed from a blank strip of relatively soft copper alloy and includes a round, smooth, protrusion-free contact end in the form of a rolled socket that is attached to conventional crimp wings by an intermediate cylindrical neck of a rolled cylindrical form. The rolled socket has an annular lip at its front end defining an entrance for plugging a terminal pin into the socket and a pair of contacts near the front end that are formed from the material of the socket. The spring member is stamped and bent from a sheet of spring material into a generally T-shaped configuration comprising a spring finger that is attached to the middle of a c-shaped support at one end. The spring member is located entirely inside the rolled socket by the deformed portions of the rolled socket in cooperation with the c-shaped collar so that the spring finger biases a terminal pin plugged into the rolled socket into engagement with the contact portions.
