Shielding of ignition wiring harness

1 GND wire splitting into 4 for the coils connected to the engine body. 1 speedo cable from the ECU to the tacho. 4 trigger cables running from the ECU to the coils. I was thinking of running an extra wire through all the harness and grounding it also in the engine body. I have attached pics of the schematic of the harness and the harness it shelf.

A shielded cable or screened cable is an electrical cable of one or more insulated conductors enclosed by a common conductive layer. The shield may be composed of braided strands of copper (or other metal, such as aluminium), a non-braided spiral winding of copper tape, or a layer of conducting polymer.Usually this shield is covered with a jacket.

In practice, a signal wire may be protected by a conductive metal mesh or tape wrapped to form an EMI shield. For sensitive circuits, a harness in which the wire/cable is routed may also be shielded. On the surface, this may seem straight forward: use a shielded wire/harness and achieve EMI protection.

SHIELDED IGNITION HARNESSES - FOR SLICK MAGS New production ignition harnesses at remarkably low prices. Late type 5MM wire constructed of 16 strands of tightly braided copper wire impregnated with scuff resistant white silicone.

Two high-voltage wiring harness samples were pre-pared for this study, as follows. - 35 mm2 shielded wire with connector A at both ends of the shielded wire. Connector A used plug type termi-nals. - 35 mm2 shielded wire with connector B at both ends of the shielded wire. Connector B used bolted terminals.

As shown in Figure 2, this presents shielding effectiveness superior to either approach alone. Increasing the performance of the Supra-Shield design is the unique triple laminate aluminum/polyester/aluminum foil tape. This tape increases shielding effectiveness through reduced shield resistance and is in contact with a drain wire to facilitate

Lightweight Metallic and Non-Metallic Cable Shielding, Tubular Braided Sleeving for Electrical Wire Interconnect Systems. Metal braided sleeving and tubular expandable braided cable shielding is used primarily in the electrical wire interconnect industry to protect cables from electrostatic and electromagnetic interference. The interwoven conductive wire acts as a ground-path barrier that ...

So, to answer the question, “What is a cable shield termination?” it is where a shield (obviously of a shielded wire) is terminated to another component. There is a wide variety of termination methods including: 1) Attaching a solder sleeve and jumper wire to the shield then the jumper wire is connected to the connector’s backshell.

shielded wiring harness is that the aluminum pipe works as both protection and shielding. In addition, it has good heat resistance and thermal conductivity, and is adaptive to various layout shapes of the pipe shielded wiring harness utilizing three-dimensional bending process, etc.(3),(4)

The use of shielding to protect wiring and signals has been around for generations, but the importance of protecting signal integrity is more important than ever in modern aircraft designs. There are multiple strategies for accomplishing this, and the implementation of shielding is entirely dependent on the performance requirement and the operation frequencies of the signal equipment.
