Patent number: 6916188Abstract: A connector assembly is provided with opposing and interengageable first and second connector components. Each of the two components preferably includes upper and lower housing formed from an insulative material coated with electrically-conductive material, with cavities formed therein that receive terminal assemblies. The upper and lower housings are formed with internal cavities that extend in orthogonal directions. Each cavity contains a terminal assembly of either plug or receptacle structure and may further include either a plurality of power terminals or differential signal terminals. The terminals have contact portions, tail portions and interconnecting portions that are partially encapsulated by an insulative outer shell. In assembling the first and second components, multiple ground connections are made in sequence before any signal or power supply connections are made.Type: GrantFiled: May 6, 2003Date of Patent: July 12, 2005Assignee: Molex IncorporatedInventors: Harold Keith Lang, Kent E. Regnier, Emanuel G. Banakis, David E. Dunham, Robert A. Owsley

Patent number: 6890215Abstract: A connector assembly is provided with opposing and interengageable first and second connector components. Each of the two components has internal cavities that contain terminal assemblies of either plug or receptacle structure and may further include either a plurality of power terminals or differential signal terminals. The terminals have contact portions, tail portions and interconnecting portions that are partially encapsulated by an insulative outer support frames. The shell forms a wafer and two such wafers are combined together to form a terminal assembly. The terminal assemblies are identical in shape, other than for an engagement means that serves to hold two subframes together as a single assembly.Type: GrantFiled: May 6, 2003Date of Patent: May 10, 2005Assignee: Molex IncorporatedInventors: Harold Keith Lang, Kent E.

Publication number: 20040097134Abstract: A shielded electrical connector is provided for mounting on a printed circuit board. The connector includes a dielectric housing having a plurality of terminal-receiving cavities and a plurality of board-engaging pads projecting from the bottom of the housing. A plurality of terminals are received in the cavities. Portions of the housing between the terminals are plated with conductive metal material to electrically shield the terminals from each other and to provide a controlled impedance.

Publication number: 20020142629Abstract: An electrical connector is provided for mounting on a surface of a printed circuit board having a plurality of holes. The connector includes a dielectric housing having a plurality of terminal-receiving passages. A plurality of first conductive terminals are mounted in some of the passages and include first tail portions insertable in an insertion direction into the holes in the printed circuit board with an interference fit. A plurality of second conductive terminals are mounted in other of the passages and include second tail portions engageable with the surface of the printed circuit board. The second tail portions are constructed to exert forces on the connector in a direction opposite the insertion direction away from the printed circuit board.Type: ApplicationFiled: March 27, 2001Publication date: October 3, 2002Inventors: Victor Zaderej, Kent E.

Patent number: 6394823Abstract: An edge card connector is provided for use with a circuit card having an edge and a plurality of contact pads near the edge. The connector includes a housing having an elongated slot for receiving the edge of the circuit card therein, along with terminal cavities adjacent to the slot. A plurality of terminals are inserted into the terminal cavities. At least some of the terminals each include a contact section extending into the slot for engaging a contact pad on the circuit card, along with an enlarged body section. A thin flexible contact arm extends between the body section and the contact section. A finger portion extends alongside the thin flexible contact arm to increase the capacitance of the terminal and, thereby, reduce the impedance of the circuit through the terminal.Type: GrantFiled: May 26, 2000Date of Patent: May 28, 2002Assignee: Molex IncorporatedInventors: David E.

Patent number: 6068504Abstract: An improved mass connector termination assembly reduces mistermination errors and gives dual termination capability for simultaneous termination of selected wires to two different terminals. This simultaneous termination also simplifies the isolation of differential signal wire pairs. Three arrays of terminals are held within a terminal housing and include elongated contact portions that extend within a plug or receptacle portion of the connector housing and insulation displacement portions that extend along a terminating face of the connector. The terminal arrays extend through the connector between these two faces. Multiple contact portions of one of the three terminal arrays are bussed together with a single terminal and these single terminals are aligned with the terminals of the other two terminal arrays.Type: GrantFiled: September 8, 1998Date of Patent: May 30, 2000Assignee: Molex IncorporatedInventors: Michael J.

Patent number: 5788535Abstract: An adaptor assembly which functions as an extender for coaxial cable connectors. The adaptor assembly includes a support element which provides for support and isolation of a terminal within an assembly housing and minimizes electrical signal degradation by providing only a minimal amount of dielectric material to support the terminal within the housing. Additionally, a metal bushing is provided as part of an auto-seizing assembly and prevents lock-up of the adaptor assembly during installation of the assembly onto a coaxial cable connector.Type: GrantFiled: September 11, 1996Date of Patent: August 4, 1998Assignee: Augat/LRC Electronics, Inc.Inventors: Vadim R.
