Global Connections: Why We Need Wire

Wire—we cannot do without it. Every cable has one thing in common—wire—the conductive metal strands that carry the signals and power between connectors. One would think that wire is but a simple part of a successful cable design. However, it would be a mistake to simplify the importance of correct wire design.

Global Connections: Staying in Spec

To ensure that your custom cable assembly meets required specifications, the fabricator needs a well-equipped laboratory. The laboratory requires a variety of specialized test equipment to ensure that the cable harness assembly meets and exceeds expected results. Typical required laboratory equipment includes high voltage test units, environmental salt spray chambers, state of the art temperature cycling units, ultraviolet aging simulators, strain and stress relief measuring equipment, and bending and flexing test equipment. Cooler Cao explains.

Global Connections: Manufacturing Complicated Multiple Wire Cable Harness Assemblies

The manufacturers of a complicated multi-section wiring harness will start with the drawings, which detail the construction, as well as specifying each required part and section of the design. A computer-aided assembly engineer will draw the wire harness design; decide the wire type, conductor size and strand count, as well as the insulative coating and color of each wires type.

Global Connections: The Process of Overmolding

In cable assembly, overmolding is the addition of various plastic coatings to seal and protect the connector and the harness. An injection die molding procedure is used, in single or multiple steps. The injected material is usually a thermoplastic elastomer; rigid first to seal and lock in the connector, then if a second overmolding is required, usually a flexible material to provide strain relief and or locking tabs.

Global Connections: Cable Assemblies—Ideas for Improved Design

When you are tasked with a new project, even though other items seem to be more important, always start any cable designs early in the process. Talk to your connector supplier at the beginning to make sure there is enough stock available for your needs. Spend time talking with the connector manufacturer or representative to ensure the chosen connectors are suitable and have a proven reliability in field life. Many connectors look good but lack reliability or lack water intrusion specifications as required.
