<p>PROBLEM TO BE SOLVED: To provide an electric junction box which can surely and easily avoid an erroneous mixed-up connection for a first power supply line connected with a battery and a second power supply line connected with an alternator. SOLUTION: If a second power supply line connection terminal 4 is erroneously connected with a first power supply line side, a corner 4-1 of the square terminal 4 interferes with an erroneous connection preventive wall 1-1 to avoid erroneous connection. If a first power supply line connection terminal 3 is connected erroneously with a second power supply line side, a tip of the circular terminal 3 interferes with a lower surface wall 1-2 of an electrical junction box to avoid erroneous connection. Further, shapes of bolt insertion holes of side walls 1-6 and 1-7 of the electric junction box are circular on the first power supply side and square on the second power supply line side according to the shapes of the respective connection terminals.</p> |
