A construction and a terminal cap for preventing an erroneous connection

摘要

To prevent batteries having different specifications from being erroneously connected by a booster cable. ÄSolutionÜ A terminal cap 10 is mounted to cover a battery terminal T to be connected with one of electrodes of a 32V-battery. In this terminal cap 10, protection walls 20 stand on edges of a first accommodating portion 11a for accommodating a connecting portion 7 of the battery terminal T. The protection walls 20 are formed to be higher than a threaded shaft 1 of the electrode. Thus, even if an attempt is made to erroneously connect a booster cable, the booster cable cannot be connected with the electrode located inside the protection walls 20 by being interfered by the protection-walls 20. <IMAGE>
