<p>PURPOSE:To make sure whether the assembly of cable accessories such as a connection box which has a cable insulator on which a premolded insulator is installed and an epoxy unit fit in on the premolded insulator with a bearing stress applied is correct or not, easily and accurately. CONSTITUTION:A bearing sensor 21 is placed between the most outer part (outer surface of a semiconductor layer 4a) of a premolded insulator 4 and an epoxy unit 2. It is decided by the existence of the output of the sensor whether a force of a spring 15 is correctly transmitted to the premolded insulator 4. In some cases, a plurality of the bearing sensors 21 are installed in the circumference direction and it is decided by the existence of a difference in the output among those bearing sensors 21 whether there is an abnormality in the distribution of the bearing stress on an interface liable for diagnosis to increase the correctness of diagnosis. By this method, the bearing sensor 21 can be connected to a detector outside and therefore the assembly is not complicated.</p> |
