PROBLEM TO BE SOLVED: To provide a high quality pressure contact terminal in which performance estimate is sufficiently conducted from a design time by designing, based on data measured under conditions similar to a practical pressure contact connection. SOLUTION: Wire insertion amount, metal piece confronting spacing, reaction force and contact resistance are measured as a wire 6 is inserted from one side between one pair of metal pieces 11, 12 side edges of which confront each other in parallel and have tapers 13 at one end portions, and insertion completion time insertion amountΔ2, insertion completion time confronting spacing WS2, insertion completion time reaction force F2, and insertion completion time contact resistance R2 are found. Simultaneously, the existence of wire strand breaking is distinguished, and the treatment is repeatedly conducted as changing initial confronting spacing WS between both metal pieces 11, 12. Based on the data, the design value of the insertion completion time confronting spacing is specified the insertion completion time contact resistance R2 is stabilized in the variation range of the insertion completion time confronting spacing WS2, and in a range where no strand breaking occurs. Simultaneously, the respective design values of the insertion completion time reaction force, and the insertion completion time insertion amount corresponding thereto are specified, and the design is conducted so that the characteristics at the pressure contact position of the pressure contact terminal meet the respective design values. |
