  • Publication number: 20070021005
    Abstract: The invention relates to a cable connector including a housing having a die-cast base substantially extending between a front side and a rear side of the connector. The connector further includes a die-cast first housing part mounted to the die-cast base such that the die-cast first housing part and a first portion of the die-cast base determine a first cable connector portion at the rear side. The cable connector further includes a metal sheet formed second housing part mounted to the die-cast base such that the metal sheet formed second housing part and a second portion of the die-cast base determine a second cable connector portion at the front side. The cable connector is suited as a high density I/O cable connector. The invention further relates to a method of assembling a cable to such a cable connector and a metal sheet formed housing part.

  • Patent number: 6174202
    Abstract: Methods and apparatus are disclosed for manufacturing and for providing electrical connectors having maximum shielding from electronic interference. Maximum shielding is inexpensively achieved by manufacturing a shield structure from a single piece of material in a manner yielding individual channels for shielding a contact terminal from the receptacle area to the tail area. Contact terminals are integrated into the shield structure via insertion molding to form a column connector module. A plurality of column connector modules are then inserted into an appropriately formed front housing. As described by the method of this invention, shielding from electronic interference occurs not only between adjacent terminals within a column structure, but also, between terminals contained in adjacent column connector modules.

  • Patent number: 5104338
    Abstract: Cover device for a flat cable having an aperture in the insulation between the conductors. The cover device comprises two opposite arms, each having a first and second end. The arm are connected by a flexible cross member. This cross member is provided with a locking lip which extends in the direction of the first end of the arms and having at its free end a locking lobe for insertion in the aperture of the cable. By making the locking lobe barb-shaped the cable can be inserted into the cover device by a snap action. Polarization-indicating means are provided for positioning the cable correctly relative to the cover device. Preferably, the cover device may be combined with an electric connector.
