An electrical junction box that improves the reliability of the electrical connections formed therein by avoiding of damage to the fork shaped terminals in the connector block by preventing the invasion of foreign objects. A shutter cover is located along the front and rear walls of the connector block to expose and cover slits which are formed at specific intervals on front and rear walls of the connector block. The shutter cover is constructed from two comb shaped side members having alternating open portions and solid portions, and a connecting portion that joins one edge of each side member. The shutter cover is attached at a position where solid portions cover the slits of the connector block before the connector block is inserted into the connector receptacle of the upper case. The complete insertion of the connector block into the connector receptacle results in the shutter cover moving to a position that aligns open portions to the slits, thus allowing the insertion of busbars into the slits.
