<p>PURPOSE:To effect DC pressure resistance test quickly with high operability by a method wherein a blank plug, attached detachably to a charging terminal when a charging cable is not attached to the charging terminal, is connected integrally to a connecting conductor. CONSTITUTION:When a high DC voltage is impressed on a cable line 20 through a charging cable to effect DC pressure resistance test, a lid 46 is removed from the side of the charging terminal B of a bushing 11 to extract a blank plug 40. When the blank plug 40 is extracted, a connecting conductor rod 15, connected integrally, is extracted out of the hollow section 10 of the bushing 11 at the same time and is removed out of the charging terminal B. Thereafter, a charging cable is attached to the charging terminal B. The connecting conductor rod 15 can be removed from or inserted into the bushing 11 by only attaching the blank plug 40 to or detaching the same from the charging terminal B in such a manner. According to this method, the DC pressure resistance test of the cable line 20 can be effected quickly with high operability.</p> |
