ABSTRACT:
A wire-receiving barrel terminal comprises first and second terminal portions 12, 32, which together define a dual contact portion 76, dual transition portion 78 and double barrel portion 80. The first and second terminal portions 12, 32, each include respective at least one contact section 14, 36, respective transition portions 16, 60 being joined integrally with and extending rearwardly from the corresponding at least one first contact section 14, 36 respectively and respective barrel sections 18, 62, joined integrally with and extending rearwardly from the respective transition portions 16, 60. The first barrel section 18 being joined integrally with and extending from said second barrel section 62, the first and second barrel sections 18, 62 being generally rectangular, each having at least one lateral edge 24, 70 and a respective lateral dimension at least equal to the circumference of a circle of a desired wire-receiving barrel inner diameter. The first barrel section 18 is formed into a barrel-shaped member 30 having its axis parallel to the at least one respective lateral edge of the first barrel section 18 and the second barrel section 62 is formed circumferentially around and adjacent the first barrel section defining a wire-receiving barrel having inner and outer walls. After forming terminal 10, first contact section 14 and first transition portion 16 extend respectively along second contact section 36 and second transition portion 60 thereby defining dual contact portion 76, and dual transition portion 78, respectively. The resulting wire-receiving barrel has substantially two wall thicknesses circumferentially therearound with no open seam and the two transition portions 16, 60 provide a plurality of contact paths for current passed through said terminal.
