PROBLEM TO BE SOLVED: To provide a twisted pair wire untwist prevention clip and the like which allow an easy and quick operation for preventing an untwist of a twisted pair wire.SOLUTION: An embodiment comprises: a wire holding part 18 to hold two wires 52 in a twisted pair wire 50; and an operation lever part 12 formed integrally with a shaft part 14 and force transfer beam parts 16 on both sides thereof, and having external-force acting parts 12b at both ends. The wire holding part 18 has: a linear part 18c as long as the outer diameter of the wires 52; and a pair of circular arc parts 18b extending from both ends thereof bilaterally symmetrically and each having a substantially semicylindrical inner surface part whose radius of curvature is equal to a half of the outer diameter of the wires 52. When compressive force acts on the pair of external-force acting part 12b such that the operation lever part 12 bends toward the opposite side of the wire holding part 18, a bending moment with a support point at the shaft part 14 acts on the wire holding part 18 on both sides of the shaft part 14, so as to expand a gap between ends of the pair of circular arc parts 18b of the wire holding part 18.SELECTED DRAWING: Figure 3
【課題】ツイストペア線の撚り戻りを防止するための作業を短時間で簡単に行うことができるツイストペア線の撚り戻り防止クリップ等を提供する。【解決手段】ツイストペア線50の2本の電線52を抱持する電線抱持部18と、軸部14およびその両側の力伝達棹部16に一体に設けられ、両端に外力作用部12bを有する操作レバー部12と、を備え、電線抱持部18は、電線52の外径に等しい長さの直線部18cと、その両端より左右対称に延在され、略半円筒状内面部を有し、かつその曲率半径が電線52の外径の半分に等しい一対の円弧部18bと、を有し、操作レバー部12が電線抱持部18と反対側に屈曲するよう、一対の外力作用部12bに圧縮力が作用する際に、電線抱持部18の軸部14の両側に軸部14を支点とする曲げモーメントが作用し、電線抱持部18の一対の円弧部18bの端部同士のギャップが拡開する。【選択図】図3
