Patent number: 5597316Abstract: Disclosed is a connector from a memory card in which the eject plate bears on the link arm at a first contact position during insertion. During ejectment a separate contact position is engaged. The distance between the first contact position used during insertion and the pivot point of the link arm is greater than the distance between the second contact position and the pivot point of the link arm by a factor of between 3:1 to 6:1. A significant mechanical advantage is therefore realized so that the card may be inserted with little resistance force while ample ejecting force is available.Type: GrantFiled: February 29, 1996Date of Patent: January 28, 1997Assignee: Berg Technology, Inc.Inventors: James J. David, Scott S. Duesterhoeft, John M. Spickler, Naoki Hiyama

Patent number: 5591048Abstract: The current invention is directed to multiple fish hook hold-downs to secure a connector housing to a circuit assembly at least prior to or during soldering of electrical terminals mounted in the connector to the circuit board. The multiple fish hook hold-down comprises contact portions whose one ends are joined together to form a common adjoining portion, intermediate portions whose proximal ends are integral with the other ends of the contact portions, and fish hook portions integral with distal ends of the intermediate portions. The multiple fish hook hold-downs are initially placed in the connector housing at the contact portion of the hold-down. Prior to assembly, the circuit assembly and the connector housing with the hold down in place may be separately transported. When assembling, fish hook portions of the hold-down are placed in a hold-down engagement hole, and the fish hook portions anchor themselves on an inside surface of the hole so as to secure the connector housing onto the circuit assembly.Type: GrantFiled: December 11, 1995Date of Patent: January 7, 1997Assignee: Berg Technology, Inc.Inventor: Marlyn E.

Patent number: 5577936Abstract: An electrical terminal carrying substrate or wafer is maintained in a channel of a die-cast metal frame of an electrical receptacle by peens that create radiused retaining lips. The slip-fit wafer is thus held into place within the channel at one end of the receptacle housing by a plurality of lips that extend over flange portions integral with the wafer. The flange rests on ledges integral with the frame within the channel. The lips and flanges eliminate interference fit wafers that tend to bow the receptacle frame increasing chances of open circuits or poor contact between the receptacle terminals and the mating plug terminals.Type: GrantFiled: September 28, 1995Date of Patent: November 26, 1996Assignee: Berg Technology, Inc.Inventor: Marlyn E.

Patent number: 5567166Abstract: A low profile connector is provided by the invention. According to the invention two sets of contacts are secured in a housing capable of being mounted to a printed circuit board so that the contacts extend laterally from the housing in parallel to the printed circuit board. A first end of each contact can be coupled to an I/O lead of a printed circuit board and a second end of each contact remains unsupported. A mating low profile connector according to the invention similarly provides two sets of contacts secured in a housing capable of being mounted to a printed circuit board so that the contacts extend laterally from the housing in parallel to the printed circuit board. The contacts are compliant and are designed to extend above the mating reference of the connector. The dimensions of the contacts are selected to provide minimum pitch and optimal compliance. A process for making the low profile connector by molding a contract strip into a housing is also disclosed.Type: GrantFiled: April 8, 1994Date of Patent: October 22, 1996Assignee: Berg Technology, Inc.Inventor: Timothy Lemke

Patent number: 5549479Abstract: A zero insertion force connector includes a pair of spring clamp jaws, each having a flexible circuit attached thereto. The clamp jaws are confrontationally arranged so that a portion of each clamp jaw adjacent to the rearward end thereof define a channel through which the flexible circuits pass. Each flexible circuit is attached to a spring clamp jaw within a region on the circuit that is free of tracings. An actuator provided within concave portions of each jaw to open the same and bring the conductive tracings on the flexible circuits into registration with the conductive tracings on a substrate. Wiping action between the tracings is generated by engagement between an abutment surface on a fixture and a camming surface carried on the connector. A centering action to register the tracings is simultaneously generated.Type: GrantFiled: April 30, 1993Date of Patent: August 27, 1996Assignee: Berg Technology, Inc.Inventors: Richard A.
