<p>An attachment for a plug includes a terminal body (2) and a terminal connector (64) having a convex portion (641) and a concave portion (642), and satisfies any one of the following conditions (A) to (C). (A) A >= 1.5, B >= 2.0, and A/B <= 7/4, where A (mm) is the length of the convex portion (641) along the center axis (CL3) of the terminal connector (64), and B (mm) is the length of the concave portion (642) along the center axis (CL3). (B) A plurality of grooves (643) is formed on the outer periphery of the convex portion (641), and the length of the grooves (643) is 0.3 mm or more and the width (W) of the grooves (643) is 0.05 to 0.25 mm. (C) 0.05 <= E-F, where E (mm) is the outer diameter of the convex portion (641) and F (mm) is the outer diameter of the concave portion (642). By satisfying any one of (A) to (C), the terminal connector (64) can be securely prevented from being disconnected from the terminal body (2).</p> |
