PROBLEM TO BE SOLVED: To provide an inexpensive and small plug superior in environmental resistance. SOLUTION: The plug 30 is provided with a center conductor pin 4 conductively connected with an insulated covered wire 3 of a connecting cord 1, an internal insulator 5 attached to an outer circumference of the center conductor pin 4, an annular conductor 7 insulated from the center conductor pin 4, fit on an outer circumference of the internal insulator 5 and conductively connected with an insulated covered wire 2 of the connecting cord 1, and an armor insulator 10 covering these. The internal insulator 5 is integrally formed so as to cover the center conductor pin 4 from the outer circumference to a rear end side. The annular conductor 7 is provided with springy protrusion parts 13a and 13b and it is fit on the internal insulator 5 by an irreversible latching and fixing means using the protrusion parts 13a and 13b. The armor insulator 10 is provided so as to cover the annular conductor 7, the internal insulator 5, a conductive connecting portion M of the connecting cord 1 and its neighborhood and it is fixed by a latching means of a recessed part 17 and a protruding groove 18 mutually fitting together with the outer circumference of the internal insulator 5 at a predetermined position. A slit 15 holding the connecting cord 1 is provided in an end of the internal insulator 5. |
