The electrical metal fittings, such as a clamp and a feeder ear, cause a fever phenomenon by the contact defect. At worst, it is caused even in the breakage of the main electrical wire, for example trolley wire and messenger wire. However, it is that an effective inspection technique can't be established against a fever phenomenon in the present. Therefore, we try to grasp the main factor that the function is lost, additionally the deterioration tendency. By these considerations, we aim to propose the effective inspection techniques against the electrical metal fittings. So, in this research, we paid attention to the case that the auxiliary messenger wire broke at the AT connector in the past. And the following examinations were done. (1) The observation of the sample after the acceleration (2) The measurement of the contact resistance, by the acceleration corrosion due to the mist of salt water (3) The energizing examination
