Abstract
An electrical contact (50) includes a forward spring contact portion (51) and an integral insulation displacement portion (60) having slots (S) formed in blades (61, 62) which terminate an insulated wire (17) and, axially spaced therefrom, a wire strain relief portion (64) which includes a resilient support having legs (63, 65) supporting the wire as embraced by crimped arms (66, 68) to hold the wire axially in a straight line relative to the slots (S) to provide a controlled height of the wire in the insulation displacement portion (60) of the contact.
Claims10
An electrical contact (50) formed of conductive sheet material for terminating an electrical wire (17) having a conductive core (18) and an insulating sheath (20) including a base (52) extending along a given axis (A), an insulation displacement portion (60) having at least one plate (61, 62) formed from said base including a slot (S) formed to include a bight (B) and sides leading to an opening taper (T) to guide the wire into the slot to penetrate the insulation sheath and engage the conductive core in a low resistance, stable interface connection, a strain relief portion (64) proximate one end of said base including at least one arm (66, 68) positioned to be crimped to embrace the said wire through an engagement of the insulating sheath characterized in that the contact further includes at least one wire support leg (63, 65) extending from said base proximate said arm to hold said wire in an approximate straight line, parallel to said base and said axis (A) extending through the said slot to minimize strains on said wire core at said interface connection.
