Patent number: 6004160Abstract: An electrical connector 2, suitable for use as a plug for a Universal Serial Bus cable assembly, includes a plurality of terminals 4 that are partially insert molded in a nonconductive housing 36. A distal end 6 of each terminal 4 is recessed from the front end 38 of the housing 36. The terminals 4 are insert molded while still on a carrier and a weakened section 14 is formed at the distal end 6. After the housing 36 is molded, a tensile force is applied to fracture each terminal 4 at the weakened section 14 so that the distal end 6 of each terminal is recessed where it cannot inadvertently contact shields 54, 64 on the plug 2 or a mating receptacle 62. The rear of the housing is overmolded, and the insert molded housing 36 includes sections completely surrounding the terminals 4 so that the overmolded material cannot flow onto a housing mating surface 42 or onto a terminal mating section 10.Type: GrantFiled: March 25, 1997Date of Patent: December 21, 1999Assignee: The Whitaker CorporationInventors: Iosif Korsunsky, Alexander William Hasircoglu, David Miller, Richard Schroepfer

Patent number: 5700151Abstract: An electrical connector assembly 2 for use in connecting parallel printed circuit boards includes a receptacle connector 4 and a plug connector 6. The receptacle connector 4 includes receptacle contacts 8, each of which includes a surface mount solder tail 16 and a mating contact section in the form of a resilient arm 26 on opposite sides of a sealing pad 18 that seals a contact insertion opening 38 when the receptacle contact 8 is fully inserted. The mating contact portion is therefore isolated from contaminating materials, such as solder flux during surface mount solder operations. The height of the connector assembly 2 can be adjusted by using plug connectors 6 of different heights with a universal receptacle connector 4. The height of the side walls 60 on the plug housing 12, between a plug mating section and contact retention section is changed for different plug connector heights.Type: GrantFiled: July 14, 1995Date of Patent: December 23, 1997Assignee: The Whitaker CorporationInventors: Iosif Korsunsky, Dimitry Grabbe, Richard C.

Patent number: 5536179Abstract: A miniature electrical connector (10) having two rows of closely spaced signal contacts (40) extending from a board-mounting face (30) to a mating face (32), and having extended height. An insert (100) is assembled within a large cavity (36) of the housing (20) to define inner walls of passageways of the housing containing the contacts (40). A planar metal member (102) of the insert can define a ground bus for preventing crosstalk between the two rows of contacts, or can facilitate assembly and retention of the insert in the housing, or both, providing very thin elongate inner walls for the contact passageways while simplifying molding of the housing.Type: GrantFiled: July 25, 1994Date of Patent: July 16, 1996Assignee: The Whitaker CorporationInventors: Billy E.

Patent number: 5495666Abstract: A method for assembling an electrical connector (10) to the edge (18) of a printed circuit board (12). A machine (50) incorporates an actuating mechanism that requires only a single input motion to achieve a variety of functional motions within the machine. The machine includes a carriage assembly (54) that moves substantially vertically within the frame of the machine to sense the thickness of the circuit board and then to align the centerline of the connector held on fixture (280) with the exact center plane (44) of the board. A slide member (140) then moves toward the connector, causing a pair of comb members (252,254) to close into position in front of the moving connector. The solder tails (38,40) of the connector (10) then enter spaced slots (260) in the edges of the comb members for support and the connector housing engages the face (272) of the combs, pushing them toward the circuit board.Type: GrantFiled: May 26, 1995Date of Patent: March 5, 1996Assignee: The Whitaker CorporationInventors: Iosif Korsunsky, Joanne E.
