Patent 7291025 was granted and assigned to Yazaki on November, 2007 by the United States Patent and Trademark Office.
A guide wall and a recessed portion for accommodating therein a female-female terminal are formed in a lower case, and in an intermediate plate, a through hole through which an electric connection portion which is in abutment with the guide wall is formed and a guide portion is provided at a lower edge portion of the through hole so formed so as to protrude therefrom so as to be brought into abutment with the electric connection portion, so that the electric connection portion is guided into the through hole. Thus, by inserting the intermediate plate between the upper case and the lower case so as to be held therebetween, the guide portion automatically corrects the bend of the electric connection portion.
