  • Publication number: 20110250801
    Abstract: A connector includes a first terminal housing for housing a plurality of aligned first connecting terminals, a second terminal housing for housing a plurality of aligned second connecting terminals, and a connecting member for collectively fixing and electrically connecting the plurality of first connecting terminals and the plurality of second connecting terminals. The insulator includes a first insulating member that is one of two divided insulators formed by dividing the insulator, and a second insulating member that is another of the divided insulators. The two divided insulators overlap when the first terminal housing is fitted to the second terminal housing, thereby forming the insulator having a predetermined thickness. A fitting groove is formed on a facing surface of one of the first and second insulating members, and a convex portion fitting to the fitting groove is formed on a facing surface of the other.

  • Patent number: 7955110
    Abstract: A connector has a first terminal housing with first connecting terminals and a second terminal housing with second connecting terminals. When the first terminal housing and the second terminal housing are mated, one side of the first connecting terminals and one side of the second connecting terminals form pairs and provide contacts, respectively. Each of the contacts is sandwiched by an insulator. The insulator has a first isolating member configured to be fixed to other side of an adjacent first connecting terminal and to cover one surface of the adjacent first connecting terminal, and a second isolating member configured to be fixed to the other side of an adjacent second connecting terminal and to cover one surface of the adjacent second connecting terminal. The insulator is formed by overlapping the first insolating member and the second isolating member when the first terminal housing and the second terminal housing are mated.
