Patent number: 7753717Abstract: A method and system for terminating a cable into a plug using a plug assembly system. Wires of the cable are exposed and dressed on to a shield. A plug body is placed over the shield. The wires are fed into wire insertion holes of the plug body. A contact holding member is placed on the plug body. A crimping tool crimps the contacts in the contact holding member through the plug body into and through the wires to achieve mechanical and electrical connection between the wires and the contacts. A cover may be used to cover the plug body, shield and wires. A crimp ferrule may be used to crimp the wires to the shield.Type: GrantFiled: May 15, 2007Date of Patent: July 13, 2010Assignee: Bel Fuse Ltd.Inventors: Yakov Belopolsky, Brian Bentley, David Gutter, Richard Marowsky, Steven Weller

Patent number: 7686650Abstract: A jack capable of handling both Category 6 and Category 7 speed communications. The jack includes a shield, a housing disposed in the shield and a contact block disposed in the housing. The contact block includes a base member and a plurality of contacts carried by the base member. Each contact includes a contact portion effective to touch a corresponding contact of a plug when the plug is inserted into the jack, a first end portion effective to be inserted into a circuit board, and a second end portion. A flexible substrate is connected to the second end portion, the substrate including a compensation circuit for the jack.Type: GrantFiled: May 15, 2007Date of Patent: March 30, 2010Assignee: Bel Fuse Ltd.Inventors: Yakov Belopolsky, David Blankenship, David Gutter, Richard Marowsky

Patent number: 7568950Abstract: A high speed jack capable of handling Category 7 communications. The jack comprises a shield and a housing inside the shield. The housing defines four distinct chambers for holding at least a first, second third, and fourth contact block, each contact block including at least two contacts. The contact blocks may be disposed symmetrically about a central axis of the housing. A horizontal shield and a vertical shield are disposed in the housing and shield the contacts from one another.Type: GrantFiled: May 15, 2007Date of Patent: August 4, 2009Assignee: Bel Fuse Ltd.Inventors: Yakov Belopolsky, David Gutter, Richard Marowsky

Patent number: 7086909Abstract: A high performance, high capacitance gain, electric connector for data transfer applications. At least eight sequentially positioned elongate contact members are connected in a series of signal pairs. A first signal pair includes a fourth contact member and a fifth contact member. A second signal pair includes a third contact member and a sixth contact member. In addition, a third signal pair comprises a first contact member and a second contact member. Finally, a seventh and an eighth contact member are in a fourth signal pair. One member of each contact member pair is configured differently from the other member of the pair, the respective contact members being oriented relative to one another such that they substantially remain in generally parallel planes, but define non-parallel paths. Each of the third and fifth contact members mounts a plate-like extension oriented in a first direction and in respective planes generally parallel to one another.Type: GrantFiled: July 6, 2005Date of Patent: August 8, 2006Assignee: Bel Fuse Ltd.Inventors: Robert G. Colantuono, Richard D. Marowsky, Jason R. Cowburn, Dennis A. Bush
