This invention provides a connector which prevents female and male terminals from coupling partially to each other upon coupling and detaching of female and male connectors. in the assembly, the male connector is provided with a guide rod (13) which projects in a coupling direction. The female connector is provided with a guide hold (20) through which the guide rod passes. Upon coupling of both connectors, the guide rod passes through the guide hole to position an insertion direction. The male terminal enters the female terminal without inclining and partially contacting. <IMAGE>
