An electrical receptacle terminal (2) comprises an inner contact (4) and an outer backup spring (6) disposed closely therearound. The outer backup spring has a pair of opposed spring members (54) disposed over cantilever contact arms (14) of the inner contact (4). The spring members (54) comprise a first spring arm (56) and lateral second spring-support arms (62) disposed substantially orthogonally thereto. The first and second spring arms are joined at a front end (64) by an L-shaped joining section (66), and separated by a slot (68) extending from the joining section (66) to a body section (42) of the backup spring. The second arms (62) of the spring member (54), substantially increase the spring force of the first spring arm (54) against which the inner contact arms (14) are biased during insertion of a complementary male tab therebetween. The spring force of the inner contact arms (14) are further increased by providing a U-shaped tab (70) folded over free end tips (22) of the contact arms to limit sliding movement thereof. The joining section (66) at the front end of the backup spring is aligned with the box-shaped body section (42) and reduces rocking of the terminal when inserted into a corresponding cavity of a connector housing. Furthermore, the inner contact body is well protected from external objects.
