  • Patent number: 4773876
    Abstract: A multi-conductor flat cable electrical connector, which comprises a plurality of terminals each having a contacting part for contact with the contacting part of a mating connector and a pressure welding part to be connected to a conductor of a multi-conductor flat cable; an insulating housing for holding said terminals in such a manner that said pressure welding parts may project therefrom; a termination member having a conductor holding recess for an end of said flat cable and adapted to be united to said insulating housing; said terminals being arranged in said insulating housing so that said pressure welding parts may be aligned in at least two pairs of lines; said pressure welding parts being arranged alternately in each of said pairs of lines at a pitch twice that of said conductors so that the pitch between said adjacent terminals may be equal to that of said conductors; said termination member having a pair of conductor arranging recesses extending laterally to either side from said holding recess and

  • Patent number: 4713025
    Abstract: An electric connector for multi-conductor flat cables comprises an insulating housing having a substantially flat end face, at least two kinds of contacts, one kind at a level of height different from that of the contacts of another kind, and at least two cable connecting members in the form of a substantially flat plate. The contacts are arranged in at least two rows extending from the end face. The pitch of or space between the contacts arranged in one row is equal to that of the contacts arranged in another row and to the pitch of the conductors in a multi-conductor flat cable to be connected.

  • Patent number: 4671596
    Abstract: An electric connector for a multicore flat cable comprises an insulating housing which has a contact arrayal surface with a plurality of press-connecting type contacts disposed at a predetermined pitch so as to protrude their press-connecting portions therefrom, and a cable wiring member which is assembled to the contact arrayal surface of the insulating housing. The cable wiring member is provided with a plurality of core wire laying slots which are formed along a periphery thereof at intervals corresponding to the predetermined pitch, and a plurality of press-connecting portion receiving flutes which are formed so as to traverse the respective core wire laying slots and which receive the press-connecting portions of the respective contacts. Each core wire laying slot receives the corresponding one of core wires disjointed at an intermediate part of the multicore flat cable so that the corresponding core wire may surround the cable wiring member.
