Electrical connector housing having conductor-retention means

Claim 1

An electrical connector, comprising: a dielectric housing having aligned contact-receiving and conductor-retaining sections opening outwardly; an electrical contact having a termination section disposed in said contact-receiving section and a soldering leg extending outwardly from a bottom surface of said housing for soldered connection to a circuit board; said conductor-retaining section having a generally semicircular portion and including a pair of resilient conductor-retention members extending upwardly from said semi-circular portion, said members including vertical legs and inwardly-directed legs, with the inwardly-directed legs being spaced from and facing one another thereby providing a groove therebetween whereby an electrical conductor can be inserted through said groove into the semi-circular portion past free ends of the inwardly-directed legs; and projections having sharp edges provided at said free ends of said inwardly-directed legs and also extending upwardly from a bottom of said semi-circular groove, said projections being disposed in a place perpendicular to an axis of said conductor-retaining section so that said projections firmly engage the insulation of the conductor when inserted within the conductor-retaining section to provide an axial strain relief thereon and to prevent the insulation of the conductor from shrinking away from the termination between the conductor and the termination section when heat is applied to said soldering leg.
