PROBLEM TO BE SOLVED: To provide a pin plug having low contact resistance, ensuring electrical connection and facilitating the distinction of the type of the cord. SOLUTION: In this pin plug 1, a cord protector 3 on which an expanded part 301 for engagement large enough to engage with an engagement hole 205 of a grip case 2 on its peripheral is formed, is inserted in the grip case 2 having the engagement hole 205 formed on a part of its peripheral surface, and a center pin 4, an earth electrode 5, a cord C and the like are mechanically fixed by internally inserting the cord protector 3 in the grip case 2 so as to engage the expanded part 301 with the engagement hole 205, and a distinguishing function of making the type of the cord distinguishable by coloring and marking the expanded part 301 for engagement is given. |
