The connector includes a dielectric housing having a plurality of terminal-receiving passages. A plurality of terminals are shaped from sheet metal material, with each terminal having a contact portion at one end and a terminating portion at an opposite end. The contact portion has a contact area which engages a mating terminal of a complementary mating connecting device. The contact portion, except for the contact thereof, or the tail portion, is selectively trimmed to a given size to vary the plate area of the contact portion or the tail portion to adjust the impedance of the terminal. This may be done by removing sections of the contact portion from the contact edges or by forming holes in the contact portions. Alternatively, to adjust impedance, a drive shoulder of the terminal may be located at a position to lengthen or shorten the contact portion or tail portion.

The tail portions of the upper terminals have intermediate portions that are bent down to descend obliquely from the rear side of the connector housing while the tail portions of the lower terminals have corresponding intermediate portions that are bent up to rise obliquely from the rear side of the connector housing. The intermediate portions of the upper and lower rows of terminals meet with the solder tail portions of the tail portions along a common length so that the tail portions of both upper and lower rows have the same electrical length. The intermediate portions of both rows of terminals are also tapered, or flared along their length so that they have a larger surface area where they exit the connector housing than where they join to their associated solder tail portions.

At an opposite side of the plug connector, a grounding spring projects outwardly from a recess in the shell for also contacting a recess in the mated socket connector.
