A connection system is provided of the type wherein a plug connector must be accurately guided to mate with a receptable connector, which minimizes the space coupled by guiding apparatus and which enables the guiding apparatus to electrically ground portions of the two connectors. The plug connector (12, FIG. 4) includes an insulative body (40) with small holes that hold signal contacts (24), the body also having larger holes (42) that hold guide pins (30) that project rearwardly further than the signal contacts to guide the connectors so they properly mate. The receptable connector (14, FIG. 5) has larger socket contacts (60) with through holes therein, which initially receive rearward guide parts (56) of the guide pins to provide the guiding function, and which then receive greater diameter contacting parts (58) of the guide pins which make good electrical contact with the socket contacts. Each guide pin has a forward contacting end (82, FIG. 4) which has resilient fingers to project through a plated hole (84) of a printed circuit board, the forward end having a taper that retains the guide pin in the circuit board.

In a module connection system wherein a plug connector at the rear of a module mates with a receptacle connector mounted on a frame, wherein the plug connector includes a body of insulative material having a plurality of small signal contact-receiving holes holding signal contacts and a plurality of larger contact-receiving holes, and wherein the plug connector also includes a shell extending around and rearward of said body, and the receptacle connector includes an insulative body having corresponding small holes holding signal contacts and a plurality of corresponding larger holes, the improvement including: a pair of guide pins, each having a forward portion retained in one of said larger holes of said plug connector insulative body, and each having a rear portion projecting rearwardly from said insulative body further than said shell; a pair of larger socket contacts each mounted in one of said larger holes of said receptacle connector insulative body and constructed to closely receive said rearward portions of said pair of guide pins; each of said guide pins has a narrower rearward guide part and a greater diameter more forward contacting part; each of said larger socket contacts has a plurality of resilient fingers that tightly engage said greater diameter contacting part of a fully inserted guide pin, and a more rearward hole that receives said narrower guide part of the guide pin.
