Abstract: An electrical cable is provided with a rounded insulated electrical conductor that transitions to a flattened section to fit into areas where the rounded portion does not fit. A round electrical conductor transitions to a flattened section for electrical conduction routing via the undercarriage of a vehicle, for routing under the carpeting of the passenger compartment, or other confined spaces. The electrical cable may illustratively be used in an electric car application where distribution of electrical current from the battery compartment to the motor requires additional wiring in the vehicle not found in combustion based engines. The reduced vertical profile of the flattened section provides for additional clearance between the vehicle undercarriage and the road, or between the undercarriage frame and the interior passenger compartment carpet.

Abstract: An electrical conductor is provided that includes at least one strip of conductive material defining a length and having a first end with a first cutout and a second end having a second cutout. The cutouts engage electrical terminals. The at least two deflections are orthogonal to the length of the strip. The deflections are located between the first cutout and the second cutout and are in plane or out of plane of the cutouts. The electrical conductor is particularly well suited for interconnection of batteries associated with a vehicle power system.

Abstract: An inventive pressurized cable is provided that simultaneously provides electrical connections and a supply of air, gas, or vacuum to an electromechanical device utilizing an existing connection on the device. The use of an existing cable connection for the supply of air or gas to provide positive pressure or a vacuum condition to an electromechanical enclosure allows for the use of standard electromechanical components without alteration and potential voiding of existing warranties. The present invention finds particular utility in the field of industrial automation where motors are subjected to coolant liquids and other types of contaminants that tend to infiltrate the motor seals, especially when the motor is shut down which causes a negative pressure inside the motor case that draws moisture in. Reactive gasses may be introduced with the inventive positive pressure cable that act to neutralize or condition harmful pollutants generated by the motor such as ozone.

Abstract: An electrical transmission cable is provided with low inductance properties capable of carrying high current loads with a more uniform heating or loss profile. The low inductance properties of the cable lead to lower current losses resulting in a cooler and more efficient operation of the cable even at higher alternating current (AC) frequencies. Higher current loads are accommodated by a plurality of conductor bundles configured as braided wire strands that are separated and joined into like conductors prior to termination. Equal lengths of the insulated wire strands within the conductor bundles contribute to uniform heating along the length of the inventive cable embodiments. Uniform operating temperature is manifest as more uniform current transmission across the various strands of an inventive cable. In addition, the more equal weave position for all the wire strands making up each braided wire bundle tends to induce cancellation of inductive effects.

Abstract: A laminar electrical connector is provided that is formed from multiple superimposed strips of conductive material that form a stack having at least two ends. A second conductive material is used to join adjacent superimposed strips. The resultant connector has ends that are adapted to engage electrical terminals and provide an electrical communication therebetween. The resultant connector lacks a sheath on the ends or a grommet extending through the stack. Such a sheath or grommet limits the operative lifetime of the resulting connector and also creates current focusing that diminishes overall connector efficiency. A connector having a continuous layer of the second conductive material joining adjacent strips along the entire interface between the adjacent strips is also provided and improves connector performance in ways that are especially beneficial to applications associated with an electric vehicle or a hybrid vehicle.

Abstract: A cable for the ultra high-speed communication of high-frequency signals. The cable includes a longitudinal conductor and an insulator sheath at least partially covering the longitudinal conductor. The cable further includes an inner conductive sheath disposed about an outer periphery of the insulator sheath and an outer insulator jacket disposed about an outer periphery of the inner conductive sheath. The insulator sheath is manufactured from a high-purity fluorinated ethylene propylene.

Abstract: A multi-lumen miniature ribbon tube is generally flat in overall shape, and includes a number of generally parallel, longitudinal lumens arranged sequentially. Each lumen includes a tubular polymer sidewall defining a separate longitudinal fluid passageway. (Here, “lumen” refers to a sidewall and passageway in combination.) The lumens are integrally formed, but may be frangible from one another. The sidewall may be made of FEP or ETFE. The ribbon tube may be as wide as 3.5 inches, and each lumen has a passageway diameter of 0.005 to 0.050 inches. Using minimum dimensions, a 3.5-inch wide ribbon tube has more than 200 lumens, each of which provides a separate fluid passageway. This enables a multiplicity of fluids to be delivered to one location. Additionally, because the lumens are frangible, one or more fluids may be delivered to multiple localized locations by separating the lumens proximate the tubing's end.

Abstract: A cable for transmitting electromagnetic signals has a central conductor. A pair of insulator filaments, each having a circular cross section, are twisted around each other to form an insulator wrap. The insulator wrap is helically wound around the conductor. An insulator sheath, provided as an outer cover for the cable, surrounds the wrapped central conductor and is supported by the insulator wrap. Since the insulator sheath is offset from the conductor, an enclosed air space is formed between the sheath and the conductor in the spaces not occupied by the insulator wrap. The twist pitch of the filaments and the pitch of the wrap around the conductor can both be modified to adjust the amount of insulator material located in the air space and thereby the cable's effective dielectric constant, which effects the propagation speed of the electromagnetic signals carried by the cable.

Abstract: A power transmitting elongate assembly transmits electrical or fluid power in a manipulative robot. At least one power transmitting elongate element has a longitudinal axis. Each elongate element is configured as an electrical cable or a fluid hose. A protective sleeve is wrapped completely around the at least one elongate element. The protective sleeve has a length and two opposite sides. Each side is disposed substantially parallel to the longitudinal axis. At least one fastener couples the protective sleeve to the at least one elongate element. Each fastener is wrapped around and/or attached to the protective sleeve. Each fastener includes two interconnecting components which interconnect with each other.

Abstract: A water cooled kickless electrical cable includes a plurality of electrical conductors. A first terminal half includes a first wire pocket hole and a fluid port disposed in fluid communication with the first wire pocket hole. A first crimp tube disposed within and extending from the first wire pocket hole is crimped around one-half of the electrical conductors associated with a first polarity. A second terminal half includes a second wire pocket hole and a fluid port disposed in fluid communication with the second wire pocket hole. The second terminal half is connected with the first terminal half. A second crimp tube disposed within and extending from the second wire pocket hole is crimped around a remaining one-half of the plurality of electrical conductors associated with a second polarity. The second crimp tube is longer than the first crimp tube.

Abstract: An electrical connector is disclosed that allows for relative twisting movement between cables or cords coupled thereto by absorbing any such twisting movement in shunts disposed internal to the connector. The shunts as well provide the communication between oppositely disposed prongs that extend from the connector housing in order to provide electrical continuity. In one form, the shunts coil around themselves internal to the connector housing as the shunts connect one side's prong to the other.

Abstract: The invention is directed to a robot arm assembly including a plurality of elongated elements for attachment with a tool carried by the robot arm assembly. The robot arm assembly includes a robot arm, an arm clamp assembly clamped around the robot arm, and at least one elongated element clamp. The elongated element clamp is connected to a mounting pad on the arm clamp and carries the elongated elements.

Abstract: The invention is directed to a fluid cooled electrical conductor assembly. The fluid cooled electrical conductor assembly includes a terminal having an open end and a fluid passage in communication with the open end. A sleeve is at least partially received within the open end of the terminal. The sleeve is metallurgically bonded to the terminal, such as by solder. The sleeve has a flared end disposed around an electrical conductor and a distal end disposed adjacent to an end of the conductor. The sleeve has a longitudinally extending groove which is in communication with the fluid passage in the terminal. A casing is connected to the terminal and surrounds the conductor to thereby define a fluid passageway at a periphery of the conductor. During manufacture, a single sleeve is swedged onto an electrical conductor and subsequently cut in half to define two substantially identical sleeves which may be inserted into respective terminals.

Abstract: A ribbon connector for use in an audio system as a speaker cable. The ribbon connector comprises two sets of flat conductors encapsulated in fluorinated ethylene polypropylene. Each of the sets is spaced apart from one another by a median strip of insulation. The median strip has a width greater than the thickness of the insulation between adjacent conductors in a set. This allows the sets to be separated from one another when a terminal is placed on each set. The conductors of a set function as a single conductor in that when used they are joined to a single terminal. The ribbon connector has enhanced capacitance and inductance characteristics compared to round twisted wire conductors.
