Continuously purchasing new cables to meet changing demands can increase costs and cut into your business’ profits. However, you can take matters into your own hands and customize your universal serial bus (USB) cables to meet your specific needs. In this article, we’ll explore the process of cutting and splicing micro USB cables, providing you with the knowledge to create the perfect cable solution for your setup.
Cutting and Splicing Micro USB Cables
The process of cutting and splicing micro USB cables requires a few basic tools and a bit of patience. Here’s a step-by-step guide to help you get started:
Cut the micro USB cable or cables you wish to splice at the desired length using a wire cutter.
Cut a 1-inch section of the plastic sheathing from the end of each wire segment using a razor blade.
Pull the metal shielding to the side and twist it into a bundle using your fingers, exposing the four internal wires.
Cut the length of the four wires in a staggered pattern to ensure a smooth splice and reduce the risk of cross-talk.
Remove a 1/8- to 1/4-inch segment of shielding from each side of the four internal wires using the razor blade.
Slip a cut segment of heat shrink tubing over each side of the internal wires and a larger piece over the cable.
Twist each wire pair together using your fingers.
Add a small drop of solder to each section of joined wire to improve physical strength and electrical conductivity.
Wrap the splice on each wire pair with a small piece of electrical tape or slide the heat shrink tubing over the splices and shrink it with a heat gun or soldering iron.
Wrap the bundle of four internal wires lightly with electrical tape, leaving the twisted metal shielding exposed.
Twist the metal shielding together with your fingers and, if desired, apply a small amount of solder.
Wrap the entire wire with electrical tape or slide the heat shrink tubing over the exposed wire splice and apply heat.
Considerations and Cautions
While splicing micro USB cables can be a cost-effective solution, it’s important to keep a few things in mind:
Soldering the wires can improve the cable’s quality and durability, but it requires caution as the soldering iron becomes extremely hot and can be dangerous.
Ensure that you maintain the integrity of the metal shielding to prevent interference and cross-talk between the internal wires.
Be aware that some micro USB cables may only have two conductors for power and not the full four required for data transfer, so your ability to transfer data may be limited.
