Connecting block assembly

1. A connecting block assembly comprising:

a plurality of connecting block parts for connecting electric components, the plurality of connecting block parts being assembled to each other,

wherein each of the connecting block parts includes:

a plurality of conductive terminals having electric connecting portions and extended portions extended from the electric connecting portions respectively; and

an insulating resin member which fixes the plurality of terminals at positions of the extended portions; and

wherein a coupling portion is formed on one side wall of the resin member in a coupling direction being perpendicular to both of an extending direction of the extended portions and an arranging direction of the plurality of terminals, and a coupled portion having a shape to be coupled to the coupling portion is formed on the other side wall of the resin member in the coupling direction.

2. The connecting block assembly according to claim 1 , wherein the coupling portion is formed in a convex shape, and the coupled portion is formed in a concave shape; and

wherein the coupling portion and the coupled portion are formed so as to be coupled to each other in a press-fitted manner.

3. The connecting block assembly according to claim 1 , wherein the plurality of terminals are fixed in the resin member by insert molding.

4. The connecting block assembly according to claim 1 , wherein other coupling portion or other coupled portion to be coupled to an adjacent connecting block in the plurality of connecting block parts, which is the other connecting block, is formed on the one side wall of the resin member in the arranging direction.

5. The connecting block assembly according to claim 1 , wherein the plurality of terminals are connected to a circuit board, and fuse terminals which are provided on fuses are connected to the electric connecting portions.

6. The connecting block assembly according to claim 1 , wherein types of the plurality of connecting block parts are different.
