In addition, for example, when a lead cable of a power source for testing is connected to the cable end mounting port 12 and the cable mounted in the cable end mounting port 13 is tested, it is prevented that a test voltage is applied to the internal circuit of the device. In order to do so, an insulating plug 21 is attached as shown in this figure. The insulating plug 21 is a tapered molded product made of rubber or the like, and a shield metal 26 is integrally molded on the back surface thereof. A push metal fitting 24 is screwed into the internal electrode 14, and the push metal fitting 24 presses the insulating plug 21 via the shield metal fitting 26 to fill the gap between the internal electrodes 14 and 15. In addition, when the insulating plug 21 is taken out later, the pressing metal fitting 24 and the shielding metal fitting 26 are connected with the connecting screw 2 so that they can be taken out together with the pressing metal fitting 24.
They are connected by 7.
