ABSTRACT:
A connector block for injectors for an internal combustion engine comprises a rod-like main stem section of a heat-resistant rigid resin having a connector portion for a wire harness and a required number of injector connecting portions disposed at predetermined intervals that are molded as integral parts thereof, and tab-like terminals are made exposed from the connector portion for a wire harness and the injector connecting portions, and bus bars are insert molded in the rod-like main stem section for effecting an electrical connection between the connector portion and injector connecting portions, whereby an electrical connection is effected between a wire harness and a group of injectors. A receptacle junction terminal having upper and lower contact sections in which tab-like terminals are inserted for connection and adapted to be accommodated in a terminal accommodating chamber of the connector block is made by blanking a single plate material into a predetermined configuration and holding the plate material so blanked into a hollow quadrilateral prism, and at least a pair of cantilever-like elastic pieces are formed, respectively, on front and back walls of said quadrilateral prism in such a manner as to protrude upwardly therefrom, and the terminal accommodating chamber accommodates the junction terminal with the top portions of the elastic pieces of the junction terminal being in press contact therewith, while a space where the elastic pieces are allowed to be elastically flexible is being provided between the inner walls of the terminal accommodating chamber and the front and back walls of the junction terminal, respectively.
