Abstract: An FCC-type modular plug, including a dielectric housing receiving a plurality of conductors. The conductors are terminated by a plurality of electrical contacts. Individual conductors are received between barriers which rise from the floor and between barriers descending from the ceiling inside of the connector in the vicinity where the conductors are terminated by the contacts. Part of each of the barriers is inclined to the ceiling and floor, respectively. The barriers form guiding grooves which guide the conductors into position for termination by insulation displacing contacts. A strain relief mechanism incorporates ratchet teeth for allowing variable movement into cable clamping position.

Abstract: An improved insulation piercing contact for use in an electrical connector is provided. The contact is made of a sheet metal stamping, which includes a top portion for making electrical contact with a first conductor, and a bottom portion which includes at least two tines. Each tine is bevelled and has a bottom edge which pierces the insulation of a second conductor and makes contact. The tines may project away from one of the planar surfaces of the contact.

Abstract: An electrical connector pin contact formed of a single blank of sheet metal including a pin section formed of a contoured strip-like portion extending outwardly from a main body part which includes a wire terminal portion to a rounded nose portion where it is folded back on itself to define two laterally spaced, medially bulged and oppositely longitudinally channeled arms, a free return end of the folded-back arm being engageable with but movable in relation to a part of the main body part to increase resistance of the bulged portions of the arms to movement toward each other when inserted in a mating socket contact. In one form the contact, which may be of either the pin or socket type, is insertable in and removable from its holder by pushing it into or out of holding engagement with a friction retaining portion.
