Cable assemblies enclose vulnerable wiring in protective sheaths and incorporate a nearly unlimited variety of connectors based on the intended use. Overmolded cable assemblies go a step beyond a simple sheath by enclosing the cable or wire and connector with overmolded material.
Cable or wire assemblies are placed within a mold, which is then injected with a pressurized molten plastic. Once the material hardens, it turns into a protective layer that seals the junction between the wires/cable and connectors to reduce the risk of damage.
Customizing your overmolded cable assemblies is the best option for ensuring your electronics are protected. They are ultimately more rugged and cost-effective because the assemblies are seamless and essentially turned into just one comprehensive piece. The overmolding process allows customization of the following:
Overmold materials. Different materials imbue the assembly with different degrees of chemical or moisture resistance, heat resistance, and more. There are a variety of common plastics available for overmolding. Polyvinyl chloride (PVC) is an inexpensive general solution, but only offers minimal protection against strong acidic chemicals. Conversely, polyethylene (PE) and thermoplastic elastomer (TPE) can withstand strong acids. Polyurethane (PU) and thermoplastic polyurethane (TPU feature good resistance to weather, aging, and other harsh environmental conditions, making them ideal for outdoor applications. Material selection is based on degrees of protection desired and compatibility with wire insulation or jacket materials.
Color. During custom projects, manufacturers can add distinct colors and resins to the molten plastic. These colors can be used to match a company’s branding, color code the assembly according to instructions or regulations, or make the equipment more aesthetically pleasing. Custom colors can improve safety and organization, as well as increase the marketability of a product.
Environmental suitability. Overmolded assemblies can be built with unique features and molded layers to protect the wires against any extreme levels of wear, stress, and abrasion that may be expected in the intended operating environment.
Regulatory compliance. Some industries maintain specific regulations regarding required levels of protection for wiring and cable assemblies. Custom overmolding processes can be customized for compliance with a variety of quality standards including IPC/WHMA-A-620 and RoHS.
Customized Overmolded Cable Assembly Applications
Custom overmolded assemblies offer enhanced strain relief and suitability for a wide range of environments. They can outlast units with multiple separate parts or thin layers of protective sheathing. Custom colors also make them ideal for complex installations or environments where visibility is poor. We’re proud to serve the following industries:

In 1994, Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel collaborated to develop the Universal Serial Bus (USB), a cable designed to standardize the connection between computers and peripheral devices such as keyboards, printers, network adapters, cameras, and storage equipment. USB was created to address usability issues , simplify software configurations, and permit greater data rates for external devices.
Shortly thereafter, in 1995, these same companies formed the USB Implementers Forum, Inc. (USB-IF) , a nonprofit organization created to support and facilitate the continuous advancement and adoption of USB technology and high-quality compatible USB devices.
In this post, we’ll be outlining the various advancements in USB technology over the years while exploring their impact on manufacturers and consumers alike.
The original USB specification, introduced in the ’90s, defined connectors with data transfer rates of 1.5 megabits per second (Mbps) as low speed, while connectors with transfer rates of 12 Mbps were classified as full speed. Today there are three major types of USB connectors — USB Type A, USB Type B, and USB Type C, each which offer their own revisions and specifications depending on bandwidth needs.
Considered the standard and most common type of connector, A-style connectors are found on the PC or charger side of most cables. This flat, rectangular interface joins directly to host devices and is held in place through friction. Durable enough for continuous connection but easy enough for users to connect and disconnect, this connector type is also available in micro variations.
Type-B USBs were traditionally used with printer cables but, with the advent of wireless printing, they’re now more often used in cell phones as Micro-USB B adapters; they’re also used in various peripheral devices  such as mobile printers and external hard drives. These USBs feature a square interface and are available as a Micro-USB B, USB Mini-b (5-pin), and USB Mini-b (4-pin).
The newest type of connector on the market, Type-C is a one-size-fits-all solution. Featuring a reversible, symmetrical interface, this thinner, sleeker design is intended to replace older, larger USBs, though it can be adapted to support legacy connectors as well. Its small size allows all devices to easily adopt the single USB connector shape, eliminating the need for various types of cables.
USB Revisions and Specifications
USBs are further classified by their power specifications. Each version now features increased bandwidth, allowing for compatibility with a broader range of devices and applications.
Though now obsolete, USB 1.1 or Full-Bandwidth USB was the first widely used consumer USB, allowing a maximum bandwidth of 12 Mbps for basic devices such as computer mice and keyboards.
Also called the High-Speed USB, version 2.0’s main improvement was the upgrade to a bandwidth of 480 Mbps ; this allows for use in higher-bandwidth devices such as adapters, transfer cables, and mass storage equipment. USB 2.0 also offers backward compatibility to support USB 1.1 devices.
USB 3.0 aka USB 3.1 Gen 1
Dubbed the SuperSpeed USB, 3.0 further improves upon the 2.0’s bandwidth, jumping to a maximum of 4.8 Gbps with backward compatibility for legacy devices.
USB 3.1 aka USB 3.1 Gen 2
A key identifier of the latest USB 3.1 is the switch to blue connectors. Quickly gaining adoption in new products like the Apple MacBook, USB 3.1 Gen 2 is capable of transfer speeds up to 5 Gbps.
USB Power Delivery Standards
Every USB advancement has offered enhanced power delivery standards and improved communication capabilities among devices.
Also Known As

As touched upon earlier, the most recent development in USBs, USB Type-C, is designed as a one-size-fits-all solution for data transfer and power supply on any device. Featuring a smaller connector, Type-C fits into one multi-use port to simultaneously charge devices and transfer data and also offers backward compatibility to support previous USB standards (2.0, 3.0, and 3.1).
USB Type-C 3.1’s reversible cable enables two-way power and data transfer, with 10 Gbit/s of bandwidth and power up to 20V at 5 Amps , or a total of 100 W — enough power to charge a laptop or provide 4K monitor resolution with one slim, streamlined cable.
A universal and nonproprietary technology, Type-C is quickly becoming the new standard for operating systems and hardware providers; Intel’s Thunderbolt recently switched to USB Type-C ports while enabling cross compatibility with USB 3.1, and Apple has announced that new MacBooks will feature a Type-C port . In fact, USB-IF predicts that by 2019, all laptops, tablets, mobile phones, and other consumer electronics will be equipped with USB Type-C.

Cabling is one of those components that people don’t often give much thought to, right? Need to power up something? Grab a cable, plug it in and go!
But, what if that cable poses risks to which you are unaware? Could the construction of that cabling system cause a weakness in the wiring?
The answers to these questions can be found in our new eBook, The Advantages of Molded Cable Assemblies. In this new resource, we provide you with information on how the protection of the terminal shells is an overlooked area that can be the difference between strong and weak cable assemblies.
Cable assemblies are highly engineered products made up of wiring, insulation, jacket, and terminals. As cable production and insulation has progressed over the years the safety of the wiring has improved tremendously. Intact cabling poses little risk of failure. The failures occur when the cables are cut and mated with a terminal. Choosing the right terminal end assembly is extremely important for all cable applications.
Terminal End and Cable Connectors
Let’s look more closely at terminal end options and the progression of cable connectors through the years. Realizing early on that joining exposed wires together was unsafe, the idea of a cable connector was born. Originally made out of porcelain or Bakelite, they were difficult to manufacture and expensive to replace.
Metal and plastic connectors prompted the replacement of these original multi-piece assemblies, and they became the standard until advancements in plastics and rubber forming led to molded cable connectors. These are the most commonly used connectors in today’s consumer electronics and appliances.
Because there are many options available for connecting spliced cables together, you need to have the most comprehensive information to understand how important it is to choose the right connector. In this eBook you will find explanations of:

Schedule a design consultation with your manufacturer. They will have design experts on staff who can meet with you to ensure the job requirements are realistic and that your part can be successfully developed. For instance, discussing material options can be greatly beneficial, as design experts may know of a better, more suitable material for your part and application. Additionally, the right assistance can significantly reduce costs without affecting quality or performance.
Was your cable assembly designed and manufactured previously? Were you dissatisfied with the quality, timing or cost? If so, it is important that you communicate this to your wire and cable manufacturer. Understanding why the part or prior manufacturing process was deficient will make it easier to address and correct these matters.
Creating a custom cable assembly can be a challenging process, so don’t hesitate to ask a cable manufacturer for assistance. Through nearly a hundred years of service, Consolidated Electronic Wire & Cable has obtained extensive engineering expertise in custom cable assemblies for a wide range of applications.
