An electronic control unit includes; a circuit board including a plurality of layers, the layers including a plurality of ground layers having different thicknesses from one another; a drain line connected to the circuit board; a switching device configured to selectively connect the drain line to one of the plurality of ground layers based on a frequency of an electromagnetic wave inside a vehicle cabin; and a controller configured to control the connection of the switching device based on the frequency of the electromagnetic wave inside the vehicle cabin.

A knuckle structure is provided with: a knuckle for rotatably supporting a drive shaft connected to the output shaft of a motor; and a grounding member having a grounding harness, the grounding member electrically connecting the knuckle and a vehicle body. The grounding member is connected to a grounding connection section provided on the protrusion of the knuckle and facing rearward of the vehicle. The grounding connection section is provided between a brake caliper extending in the front-rear direction of the vehicle and the knuckle.

A wiring structure according to the present disclosure includes a shield tube, a metal wire, and a plate-like member. The shield tube covers a wiring. The metal wire fixes the shield tube. The metal wire fixes the shield tube to the plate-like member by pressing the shield tube against the plate-like member. The plate-like member is connected to a grounding path in a manner that enables electric conduction. The shield tube is connected to the grounding path via the plate-like member in a manner that enables electric conduction.

Disclosed is a shielding structure for an integrated inductor/transformer, configured under the integrated inductor or the transformer and upon a substrate. The shielding structure includes conductive units, first connecting portions, via holes, a second connecting portion and a grounding portion. Each conductive unit includes a first conductive portion and second conductive portions extending from the first conductive portion. The number of the second conductive portions is odd. The length of each second conductive portion progressively diminishes from a center of the first conductive portion to both of two ends of the first conductive portion. The first connecting portion connects the first conductive portions of the conductive units through via holes. The grounding portion is connected to one of the first conductive portions. The second connecting portion connects all longest second conductive portions together. Moreover, the conductive units and the second connecting portion are made of different conductive materials.

A connecting element for galvanically connecting two electrically conductive surfaces, comprises: a body plate having a body plate upper surface defining a body plate top level; and a spring tab extending from the body plate and having a spring tab upper surface comprising an upper contact section above the body plate top level. The connecting element has a connecting element bottom level, and the spring tab has a spring tab lower surface comprising a lower contact section, the spring tab having a rest position in which, with no external force applied onto the upper contact section, the lower contact section lies above the connecting element bottom level, and is bendable, by applying external force onto the upper contact section, to a compressed position in which the lower contact section lies in or below the connecting element bottom level.

A patterned ground shield includes a plurality of portions, a first connection member, a second connection member, and a third connection member. Each of the first connection member and the second connection member is coupled to any of two of the portions which are not adjacent to each other. The third connection member is coupled to two of the portions which are adjacent to each other.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about -20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.
