A terminal (10) for an electrical connector (1). The terminal (10) comprises a mating portion (14) for mating with a contact of a mating connector, restraining means (58) for blocking withdrawal of the terminal (10) from the connector (1), and an elongate terminating portion (16) adapted to project from the connector (1). The terminating portion (16) comprises a leg (20) for terminating the terminal (10) to the substrate (4) and positive retention means (62) for securing the terminal (10) to the connector (1). The positive retention means (62) comprises a portion of the terminating portion (16) being adapted to be deflected at substantially a right angle. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With more particular reference to the drawing, FIG.
1 shows an exploded view of a connector assembly 1 in accordance with the present invention.
The connector assembly 1 electrically connects a wire 2 to a substrate 4, for example a printed circuit board.
The connector assembly 1, shown with the wire 2 connected to a contact 6, comprises a housing 8, terminals 10, and a header 12.
While the contact 6 may be of any type, it is preferred that the contact 6 be dual beam, and more particularly one similar to the receptacle contact part number 555485-1 shown on page 7 of AMP Catalog 89-867, INNERGY Power Distribution System for Modular Office Panels, issued December 1989, so as to mate with a plug style of terminal.
(INNERGY is a trademark of AMP Incorporated.
) The terminals 10 are stamped from flat stock, preferably copper alloy which is selectively plated with tin or silver.
With reference to FIGS.
2 and 3, each terminal 10 comprises a mating portion 14 and an elongated terminating portion 16 projecting from an edge thereof.
The mating portion 14 also includes shoulders 18 which assist in securing the terminal 10 in the header 12.
The terminating portion 16 is for being terminated to the substrate 4, and ends with parallel legs 20, preferably two or more.
Multiple legs 20 are used for more efficient heat dissipation and lower voltage drop to the substrate 4.
The header 12 is made of a dielectric material, preferably polyphenylene sulfide (PPS), and is adapted for mounting on the substrate 4.
With reference to FIGS.
1 and 4, the header 12 has a body 24, mounting ears 26 at opposite ends of the body 24, a mounting face 28, a mating face 30 opposite the mounting face 28, and, within the body 24, a plurality of terminal receiving cavities 32 each with a floor 34 at the mounting face 28 extending to the mating face 30.
Each terminal receiving cavity 32 has safety means 36 for protecting a technician from electrical shock by covering the terminal 10
