An arrangement for electrically conductively connecting a cup shaped copper contact part to an electrical conductor that is made of a plurality of individual wires containing aluminum. The arrangement has a cup-shaped contact part, which includes a bottom and a cylindrical sleeve integrally connected to and projecting away from the bottom with tight contact of the sleeve to the conductor. The cup-shaped contact part is configured to be pushed onto the conductor until the end face of the conductor rests against the bottom of the contact part. At least one rotating tool is configured to be removably placed with sustained pressure, subsequently to the cup-shaped contact part, until the material of the conductor is softened due to the increased temperature of the material of the conductor due to friction to such an extent that it integrally connects to the contact part.

A coaxial connector in combination with a coaxial cable is provided with an inner conductor supported coaxial within an outer conductor, a polymer jacket surrounding the outer conductor. A unitary connector body with a bore is provided with an overbody surrounding an outer diameter of the connector body. The outer conductor is inserted within the bore. A molecular bond is formed between the outer conductor and the connector body and between the jacket and the overbody. An inner conductor end cap may also be provided coupled to the end of the inner conductor via a molecular bond.

High speed connector inserts and cables having improved heat conduction, high strength, and may be manufactured in a reliable manner. One example may provide a connector insert having several paths by which heat may be removed from circuitry in the cable insert. In one example, heat may be removed from one or more circuits by forming a thermal path between a circuit and a shield of the connector insert. Another path may include one or more pads on a side of an integrated circuit board that are soldered directly to the shield. A braiding surrounding a cable may be soldered or otherwise thermally connected to the shield. Another example may provide a cable having a braiding that includes one or more types of fibers, such as aramid fibers. Another example may provide for increased manufacturability by using a wire comb and a solder bar.

A high-frequency transmission line includes an insulator as a base material, and also includes linear conductors configured to transmit signals. Through holes are provided at positions corresponding to the positions of the linear conductors. The high-frequency transmission line is arranged on a connector in a state in which the positions of the bottom ends of the through holes are respectively aligned with the positions of signal terminals provided on the connector. A conductive bonding material provided at the top ends of the through holes is fluidized when heat is applied thereto, and flows to the bottom ends of the through holes due to surface tension or capillarity. As a result, the linear conductors are electrically connected to the signal terminals respectively.

In a method for attaching a connector to a coaxial cable a solder preform is placed upon an end of an outer conductor of the cable. A connector body of the connector is seated upon an interface pedestal and the end of the outer conductor is inserted into a bore of the connector body against the interface pedestal. The outer conductor, the connector body and the interface pedestal contribute sidewalls to form a solder cavity, and the solder preform is heated. A seat may be applied to the interface pedestal to provide a thermal barrier and/or enhanced seal characteristics that are cost efficiently replaceable upon degradation.

A battery module includes a plurality of battery cells arranged in a first direction, each one of the plurality of battery cells having a terminal portion on an upper surface thereof, a bus-bar holder positioned on the plurality of battery cells, the bus-bar holder having an opening exposing terminal portions of the plurality of battery cells, a bus-bar positioned in the opening of the bus-bar holder, the bus-bar being spaced apart from a circumference of the opening of the bus-bar holder by a predetermined interval, and the bus-bar electrically connecting terminal portions of adjacent battery cells among the plurality of battery cells, a guide portion extending along the opening in the first direction, the guide portion extending upward above the opening, and a fixing member on an inner surface of the guide portion.

A method of forming a solder joint between a coaxial cable and a coaxial connector includes the steps of: positioning a solder element between an end of an outer conductor of the coaxial cable and a connector body of the connector, wherein the solder element is positioned within a vacuum chamber; melting the solder element to form a solder joint between the outer conductor and the connector body, the solder joint including a lower surface formed by contact with a mounting structure; and applying suction to the melting solder element to reduce the formation of bubbles within the solder joint.

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

A coaxial connector in combination with a coaxial cable is provided with an inner conductor supported coaxial within an outer conductor, a polymer jacket surrounding the outer conductor. A unitary connector body with a bore is provided with an overbody surrounding an outer diameter of the connector body. The outer conductor is inserted within the bore. A molecular bond is formed between the outer conductor and the connector body and between the jacket and the overbody. An inner conductor end cap may also be provided coupled to the end of the inner conductor via a molecular bond.

A method of heat shrinking a protective sleeve onto an electrical connection includes an initial step of providing an electrical connection, such as between an electrical wire and an electrical termination device, and a protective sleeve having an inner surface and an outer surface. The inner surface of the protective sleeve has an adhesive material applied thereto and is disposed about the electrical connection. Thermal energy is applied to the outer surface of the protective sleeve so as to increase the temperature thereof. Either before, at the same time, or after this step, the temperature of some or all of the electrical connection disposed within the protective sleeve is increased, such as by induction heating. As a result, the protective sleeve shrinks onto the electrical connection, and the adhesive material forms a tight bond between the protective sleeve and the electrical connection.
