An insulation displacement terminal of a high quality and high performance produced by designing the terminal in accordance with data measurement under a condition similar to an actual insulation displacement connection. An extent of insertion of insulation sheath electric cable 6, a distance between a pair of metal blocks 11 and 12 parallel to each other; and a reaction force and a contact resistance acting between cable 6 and spaced metal blocks 11, 12 is measured while inserting cable 6 into a gap between metal blocks 11 and 12 which have a tapered portion on an end of each block. After completing insertion, the extent of insertion of cable DELTA2, gap distance WS2, reaction force F2, and contact resistance R2 are obtained and, at the same time, the presence of broken wires (if any) in the cable is determined. These steps are repeated while changing initial gap WS between metal blocks 11 and 12. A range in which contact resistance R2 after completing the insertion becomes stable and breakage of wires is not caused is set to be an allowable range of gap WS2. From the foregoing data, the corresponding reaction force and extent of complete insertion are set. Consequently, the insulation displacement terminal at an insulation displacement position is determined to meet the above-set values. |
