Waterproof terminal block unit with insulating plate

摘要

A terminal table unit includes: a terminal table ( 10 ) having a metal terminal ( 12 ) at its lower surface for connecting a lead wire ( 60 ); an insulation plate ( 20 ) adhered to the lower surface of the terminal table and having a hole ( 20 - 1 ) at a portion corresponding to the portion containing a metal terminal and its surrounding region; and a metal plate ( 30 ) having an upper surface adhered to the lower surface of the insulation plate and having a through hole ( 30 - 2 ) reaching from the upper surface to the lower surface. Through the through hole ( 30 - 2 ), the lead wire is brought out to the lower surface of the metal plate. The terminal unit has a contact surface between the insulation plate containing the hole ( 20 - 1 ) and the terminal table, a contact surface between the insulation plate and the metal plate, and the through hole ( 30 - 2 ) which are filled with adhesive and unified by a bolt ( 40 ).
