A multi-conductor bus with radially arranged conductor wires on which addressable bead devices that may incorporate light-emitting diodes (LEDs) or other surface mount devices (SMDs) can be easily mounted. The radial bus is designed to provide an improved range of flexibility and motion while allowing for easy addition of bead devices along its length that utilize self-addressing bus protocols such as cascading device protocols. The design of the flexible, interruptible radial bus facilitates the use of pass-through and interrupted paths along the bus that simplifies the installation of addressable devices along the bus such as the bus-mounted bead devices disclosed herein.

An automobile connection cable is configured with a controller area network (CAN-bus) circuit design and provided with a protocol interface between the J533 connector and USB Type-C. The function of switching between different protocols is achieved through the configuration of the cable assembly, so that the driver-assistance system ensures a better adaptability to the VAG vehicle models of Volkswagen Corporation (VAG). When the vehicle is shut off, the circuit control board can also control the constant power supply system between the external device and the vehicle, thereby reducing power consumption.

The present application discloses a radio frequency (RF) cable head and an RF performance testing device. The RF cable head includes a cable head housing, a first connector and a second connector. Both of the first connector and the second connector are disposed inside the cable head housing. The first connector is provided with a spring connected with the second connector, and the cable head housing is provided with a probe hole. The RF performance testing device includes the RF cable head.

An electrical cable includes a plurality of electrical lines extending from a first section to a third section through a second section. Each electrical line is enveloped by an insulating sheath. The electrical lines are arranged side-by-side in the first section in a first plane and in the third section in a third plane. The insulating sheath is integrally formed as a first insulating section in the first section and as a third insulating section in the third section. The insulating sheath is divided into a first further insulating section and a second further insulating section in the second section that are separated from each other by a gap. The first further insulating section is guided from the first insulating section to the third insulating section in a first arcuate path and the second further insulating section is guided from the first insulating section to the third insulating section in a second arcuate path.

A multi-phase busbar for conducting electric energy includes: an insulating base layer made of an insulating material; a first conducting layer made of a sheet metal arranged on and adhesively bonded to the base layer; a first connecting pin mounted to the first conducting layer which extends in a direction with respect to the first conducting layer; a first insulating layer arranged on and adhesively bonded to the first conducting layer; a second conducting layer made of a sheet metal arranged on and adhesively bonded to the first insulating layer, the second conducting layer including a second connecting pin which extends in a direction parallel to the first connecting pin; and a second insulating layer arranged on and adhesively bonded to the second conducting layer. The second conducting layer and the first and second insulating layer each include at least one pinhole through which the first connecting pin projects.

A wiring harness assembly includes a plurality of separated conductors formed of an electrically conductive material, a substrate formed of a dielectric material encasing the plurality of separated conductors, a location feature integrally formed with the substrate and an opening defined in the substrate having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature.

A cable includes a cable core formed of an electrically conductive material and an insulation at least partially encasing the cable core. The cable core is exposed in a contact zone in which the cable contacts an electrical conductor. A surface of the contact zone is filled substantially flush with a cable surface of the insulation.

A bus bar electric wire includes a flat conductor which is formed of aluminum and inevitable impurities, and which has a cross-section of a substantially rectangular shape. An area of the cross-section is 15 mm.sup.2 or more and 240 mm.sup.2 or less. The flat conductor includes a bent portion having a predetermined bending R in a plane direction of the flat conductor, and a conductor part that is an outermost side of a bend in the bent portion has a plate width being set within a range satisfying uniform bending of the conductor part.

A wire harness has: wires each including a core wire that is formed from a conductor and an insulating covering that covers the outer periphery of the core wire; and an exterior material and a braided member, into which the wires are inserted. Each wire has a removed-covering section where the insulating covering has been removed partway in the longitudinal direction. The removed-covering section is covered by a webbed covering member, the outer periphery of which has insulating properties.
