It is formed. In each of the relay block 1141 for the center and the relay block 1142 for the right end, a concave structure 1241 that is recessed from the left connection surface 1163 is formed.

  The concave structure 1241 has a shape that matches the convex structure 1240. In the relay block 1021 adjacent in the left-right direction 1120, the convex structure 1240 of the relay block 1021 on the left 1184 is inserted into the concave structure 1241 of the relay block 1021 on the right 1185.

  Due to the convex structure 1242 and the concave structure 1243, the relay block 1021 does not shift to the upper 1180, the lower 1181, the left 1184, and the right 1185 parallel to the front connecting surface 1161 and the rear connecting surface 1162.

  The structure 1040 belonging to each of the relay blocks 1021 other than the front end may be formed with a recessed structure that is recessed from the front connection surface 1161. In this case, the structure 1040 belonging to each of the relay blocks 1021 other than the rear end is formed with a convex structure protruding from the rear connection surface 1162.

  The convex structures 1240 and 1242 have a quadrangular prism shape. The shape of the convex structures 1240 and 1242 may be changed. For example, the convex structures 1240 and 1242 may be cylindrical.

(fuse)
The fuse 1023 is an in-vehicle blade fuse. The fuse may be a fuse other than a vehicle-mounted blade fuse.

  As shown in FIGS. 2, 3, and 5, the fuse terminals 1080 and 1081 protrude from the housing 1083 downward 1181. Fusing body 1082 is accommodated in housing 1083. One end of the melted body 1082 is coupled to the fuse terminal 1080. The other end of the melted body 1082 is coupled to the fuse terminal 1081. When a large current flows between the fuse terminals 1080 and 1081, the melted body 1082 is melted and conduction between the fuse terminals 1080 and 1081 is cut off.

  When the fuse 1023 connects the relay block 1021 adjacent in the left-right direction 1120, the fuse terminal 1080 is inserted into the right connection fuse terminal hole 1204 of the relay block 1021 on the left 1184, and the fuse terminal 1081 is on the right 1185. The relay block 1021 is inserted into the fuse terminal hole 1203 for the left connection, and the housing 1083 is used for the left connection of the housing groove 1223 for the right connection of the relay block 1021 of the left 1184 and the relay block 1021 of the right 1185. Is inserted across the housing groove 1222. The fuse terminal 1080 contacts the electric wiring 1041 belonging to the relay block 1021 on the left 1184 inside the fuse terminal hole 1204 for right connection, and is electrically connected to the electric wiring 1041 belonging to the relay block 1021 on the left 1184. The fuse terminal 1081 is brought into contact with the electric wiring 1041 belonging to the relay block 1021 on the right 1185 inside the fuse terminal hole 1203 for left connection, and is electrically connected to the electric wiring 1041 belonging to the relay block 1021 on the right 1185. .

  The housing groove 1223 for right connection is shallower than the fuse terminal hole 1204 for right connection, and the housing groove 1222 for left connection is shallower than the fuse terminal hole 1203 for left connection. Therefore, when a force is applied to pull the relay block 1021 adjacent in the left-right direction 1120 apart in the left-right direction 1120, the fuse terminal 1080 is caught in the housing groove 1223 for right connection, and the fuse terminal 1081 is in the housing for left connection. It is caught in the groove 1222. The hook of the fuse terminals 1080 and 1081 prevents the relay block 1021 adjacent in the left-right direction 1120 from being pulled away in the left-right direction 1120.

  Similarly, when the fuse 1023 connects the relay block 1021 adjacent in the front-rear direction 1121, the fuse terminal 1080 is inserted into the fuse terminal hole 1202 for the rear connection of the relay block 1021 at the front 1182, and the fuse terminal 1081 is at the rear 1183.
