Patent number: 7000302Abstract: Radio frequency cables have a inner circular conductor and an outer circular conductor. The inner and outer circular conductors are usually formed from copper and are separated by a heavy insulation layer usually cellular polyethylene. The outer side of the outer conductor may further be coated with a heavy polymeric insulation layer. In preparing these radio frequency cables for coupling it is necessary to have a flush cut surface. These flush cuts have been effected in the past by sawing, which has proved to be troublesome as metallic particles are dispersed throughout the insulation. The outer conductor may be prepared for coupling by: 1. Placing a tear collar over the outer conductor and 2. Tearing the outer conductor against the tear collar. This tearing creates an integral and desirable flange in the tearing process.Type: GrantFiled: September 19, 2002Date of Patent: February 21, 2006Inventor: Skip A Pierce

Patent number: 6539621Abstract: The present invention provides a safety guard for a type-N coaxial connector that prevents casual human contact with a conductive center pin of the coaxial cable. The safety guard is preferably made of a dielectric material and is generally tubular in shape. The safety guard is adapted to be installed on existing connectors in the field, or to be part of a connector assembly that is to be installed on a coaxial cable. Among the advantages of the present invention are substantial reduction in complexity over prior art interlock connector designs. The safety guard of the present invention is provided for a male connector only, thereby alleviating the need for modification of the mating female connector.Type: GrantFiled: May 22, 2000Date of Patent: April 1, 2003Assignee: Applied Materials, Inc.Inventors: William N. Taylor, Richard R. Mett, Mark W. Curry

Patent number: 6536103Abstract: A coaxial cable installation tool useful for folding back an exposed portion of grounded shielding on the end of a coaxial cable in preparation for the attachment of the coaxial cable to a coaxial cable connector. In a preferred embodiment, the installation tool includes a handle portion that is adapted to be comfortably grasped by an installer, and a flaring tool recessed within one end of the handle portion. The flaring tool includes a spring-loaded cylindrical flaring rod slidably mounted within a coaxial tubular housing. The flaring rod has a cylindrical receptacle in the leading end thereof, the diameter of the cylindrical receptacle being dimensioned to receive the portion of the coaxial cable underlying the grounded shielding therewithin. The inner diameter of the receptacle permits the snug insertion of a variety of coaxial cable connectors, such as, for example, F-type connectors, thereinto.Type: GrantFiled: August 24, 2000Date of Patent: March 25, 2003Assignee: Holland Electronics, LLCInventors: Michael Holland, Yeh Min-Hua

Patent number: 6527561Abstract: A connector (6, 7, 18, 23) has at least one free-standing pin (8 to 11; 19 to 22; 24, 25), which can be connected to a conductor of a printed circuit board (28). For producing the connector, a profiled, prism or rod-shaped starting body (30) is, on one end thereof, machined by turning around an axis (A) such that at least one pin is formed from an edge or profiling of the starting body. The method is significantly more economical than prior art milling methods and results in the production of especially stabile pins in the case of an extruded starting body.Type: GrantFiled: April 27, 2001Date of Patent: March 4, 2003Assignee: Huber + Suhner AGInventor: Peter Glauser

Patent number: 6523252Abstract: The invention relates to a coaxial conductor having an inner conductor (S), an outer conductor (U) encasing the inner conductor (S) at least partly, and a dielectric (E) placed between the two. The coaxial conductor (K) is formed in a multi-layer circuit board (M) primarily by means of vias (2a-2h) and strip conductors (1a-1i). According to an embodiment of the coaxial conductor of the invention, the inner conductor (S) is formed substantially parallel to the board layers (3a-3e) of the multi-layer circuit board (M), the inner conductor (S) is formed of at least one strip conductor (1a, 1b) or at least one electroconductive via (2a) or a combination of the same, and the outer conductor (U) is formed of at least four electroconductive vias (2b-2h) and at least two strip conductors (1c-1i). The dielectric (E) is at least partly formed of the material of the board layers (3a-3e). The invention relates also to a method for manufacturing this coaxial conductor.Type: GrantFiled: October 21, 1998Date of Patent: February 25, 2003Assignee: Nokia Mobile Phones LimitedInventor: Markku Lipponen

Patent number: 6505399Abstract: An improved cable preparation tool and an accompanying method which, when utilized concurrently, prepare fully shielded cables for termination into connecting devices. A preferred embodiment of the tool has hinged first and second tool handles biased together about a hinge by a resilient member. One end of a tool handle is fitted with a receptacle to receive and mount a detachable blade cartridge assembly which cuts the cable jacket and shielding metallic foils wrapped around individual pairs of insulated wires. A second receptacle is provided in either tool handle to receive a detachable template cartridge assembly which is used to properly position wires for termination into a connector. An exemplary method of cable preparation using the tool includes removing a cutting a cable jacket, cutting a plurality of foils and aligning wires using a single cable preparation tool.Type: GrantFiled: October 16, 2001Date of Patent: January 14, 2003Assignee: The Siemon CompanyInventors: Denny Lo, David Valentukonis

Publication number: 20020194728Abstract: This invention relates to an improved coaxial cable preparation tool (1) that is used to prepare a coaxial cable terminal end for connector installation. The tool comprises two stages. The first stage, the jacket stripper, is used to trim the cable jacket. The second stage (20), the cable trimmer, is used to trim the remaining center, the outer conductors and the foam insulation of the coaxial cable. The first stage (10) consists of a cup or cylinder (11) with an outer cylindrical wall (12). In addition, it also comprises a blade (13) and a scrap port (14). In addition, the first stage cylinder (11) has a bore (16) extending axially down its center. The diameter of the bore (16) is set to receive a coaxial cable. The second stage consists of a hub (21) (or cutter head), a collet bearing (22) and a body (23). In addition, like the first stage, it also contains blades (13) and scrap ports (14). The scrap ports or debris ports (14) allow trimmed cable media to escape from the bores in the tool.Type: ApplicationFiled: June 22, 2001Publication date: December 26, 2002Applicant: Radio Frequency Systems, Inc.Inventors: Rob Hathaway, Vinny Benevento, John Goldenberg

Publication number: 20020194726Abstract: A mold structure of an extrusion tool for extruding and sealing a connector is disclosed. The mold structure is capable of being inserted into a mold supporting seat for receiving a coaxial cable; the mold structure clamping the coaxial cable. The mold structure has the following components. A seat is installed with a hole for receiving a coaxial cable. A chuck passes through the seat so that the chuck can move toward or leave away from the coaxial cable along an axial direction. A movable element is installed at one side of the seat for control an extent of movement of the chuck moving toward the coaxial cable along an axial direction. Thereby, the chuck moves toward or leaves from the axial direction; and the coaxial cable is clamped and fixed by a sufficient force.Type: ApplicationFiled: June 25, 2001Publication date: December 26, 2002Inventor: Chi-Fu Chang
