What is Consumer Electronics?

Home or consumer electronics refers to any analog or digital devices used daily in private homes, including communication, recreation, and entertainment equipment. It is often referred to as black goods because they mainly come in darker colors. In comparison, devices used for housekeeping and cleaning, such as fridges and washing machines, are referred to as white goods because they generally come in light colors. However, today the line between white and black is somewhat blurry. In the British English Community, sellers and producers refer to some products as brown goods. Most large consumer electronics stores that sold white and black goods in the past had no distinctions.

In the early 20th century, radio broadcasting introduced the broadcast receiver, the first major consumer product. Later other products were developed, such as TVs, calculators, telephones, video recorders, mobile phones, gaming consoles, MP3 players, and personal computers. In the 2010s, more consumer electronics were developed, such as car stereos, GPS, electronic music instruments, video game consoles, video players, digital cameras, and karaoke machines. Stores began selling smartphones, cellphones, small light fixtures, camcorders, and digital cameras. Some newer consumer products include smart home devices and VR head-mounted devices. Over time consumer products began merging with digital technologies and began increasingly called the consumerization of information technology. Today consumer electronic stores also sell baby and office furniture. Furthermore, the stores have expanded combinations of both physical and online stores.

Consumer Cable Assembly Understanding

Manufacturers designed wiring harnesses for use in various electronic products and home appliances. These electronic and home items are key in exchanging signals or data and supplying power. When used in mobile phones, PCs, TVs, gaming instruments, or digital cameras, professionals refer to a wire harness as a consumer-use wiring harness.

How to Design Consumer Appliance Wire Harness

Here are some key points to consider when designing your wire harness:

  1. Every component of the harness could affect the finished product.
  2. To serve specific environmental conditions, you must design coverings, wires, and connectors.
  3. Always consider operating temperature, voltage, and amperage when making decisions.

Wire Harness Assembly

  1. The length of the wire does not necessarily determine its price because assembly time has a heavier impact on the cost should you make a mistake.
  2. A common mistake people make is during the routing and bunching of wires. Ensure you lay out the wires clearly to avoid making mistakes.
  3. Because of the large potential of terminations, ensure the design is simple to avoid placing terminals in the wrong place.

Wire Harness installation

  1. Here, the wire and heat-resistant connectors’ costs are lower than the cable installation. Therefore, ensure to keep that in mind while making decisions.
  2. Although spinal cord designs have more wires than spider web designs, they are easier to install and service.

The Connectors

  1. Your connector choice depends entirely on the speed and type of signal you plan to transmit.
  2. If you plan on sending power through, opt for a crimp-type connector.
  3. Also, choose a welded or soldered connection if you intend for it to transmit a high-speed signal.
  4. Keep in mind the final assembly has a specific connector. Therefore, you have limited terminal choices.

The Conductor or Circuits

  1. The number and type of conductors or circuits depend on your application.
  2. Copper is often the preferred conductor material because it is compatible with various coatings slowing the corrosion rate.
  3. You could use copper alloys or copper-clad steel if you need more breaking strength.

The Coverings

The wire covering offers an extra layer of protection and insulation against fluids, chemicals, abrasion, heat, vibration, moving parts, rattles, moisture, and rattles. Also, flexible wire coverings protect against EMI.

Some wire coverings include:

  • Cable protection sleeve: Wrap or expandable sleeving is easy to install and highly flexible, enabling quicker wire bundling. Often, braided sleeves use PET because of their lightweight design, durability, and flexibility, even under low temperatures.
  • Tape: You can find pressure-sensitive single-coated tapes in many backing materials and adhesives. You can use PVC as the backing material. However, some tapes use felt, foil, cloth, or foam. With tapes, stiffness is often an issue because it minimizes flexibility.
  • Heat shrinking tubing: This tubing wraps around wires, smoothing the surface and providing electrical and thermal insulation. Also, adhesive-backed tubing serves as a seal against chemicals and moisture.
  • Split loom tubing: This has a slit on the sides of the covering for easier wire insertion. After installation, you must seal the slit to eliminate the need to heat shrink or spot tape. There are several materials, with the common choices being split wire mesh loom and steel braided wire loom.
  • Spiral wrap tubing: It allows wires to exit and enter the covering at multiple points. Professionals often use polyethylene and polyamide, available in various colors for easier identification.

Consumer Cable Assembly: Environmental Considerations

When designing a wire harness, it’s important to consider every aspect of the design, particularly the environment you’ll expose it to. Consider the following:

  1. Can every component withstand the required operating temperature and voltage?
  2. Are the harness mounting and connector designed to relieve pressure from extreme vibrations?
  3. Does your harness need to contend with moisture, detergents, or grease?
  4. Is flammability a concern?

Consumer Cable Assembly: The Safety Standard

Safety is vital when designing a wire harness. Therefore, ensure your design complies with the necessary standards, keeping in mind that every country likely has different federal standards enforcing the testing and certification of electrical devices. Most countries use the following guidelines as the backbone of their standards.

  • International Electrotechnical Commission
  • European Committee for Electrical Standardization
  • International Commission for Rules for the Approval of Electrical Equipment

The IPC/WHMA-A-620 Standard Revision C is the only industry standard for Requirements and Acceptance of Cable and Wire Harness Assemblies. And the WHMA and IPC are continually working on developing helpful updates. 

Consumer Cable Assembly: The Environmental Standard

You should be familiar with the three standards limiting the use of hazardous substances:

The WEEE Directive governs the disposal and recycling of electrical products once they’re no longer usable.

In addition, concerning the safety and federal environmental standards, assemblies may have to meet standards based on specific performance criteria. Also, depending on your intended application,  you may have to meet additional standards and certain criteria, such as QSFP, HDMI, or independent testing services such as ETL.
