What You'll Learn

Using a crimp connector
To begin, you will need to strip about a quarter of an inch of insulation from the end of each wire using a stripping tool. You can do this by inserting the wire into the appropriately-sized hole in the wire strippers and pulling until the plastic insulation comes off, revealing the wire underneath. Next, twist the exposed wire ends together to make them denser and ensure a more positive connection.
Now, insert the stripped part of one wire into the crimp connector, pushing it all the way up to the insulation. Repeat this step with the other wire. Then, place the crimp connector into the notch in the crimping tool and squeeze until the crimp bends into a "U" shape. Continue squeezing and moving down the length of the crimp until you have a rut along it.
Finally, give the wires a strong pull to ensure they are connected securely. You can also seal the terminal with electrical tape or heat shrink tubing to prevent corrosion.

Applying electrical tape
While taping wires together with duct tape or electrical tape is not recommended as a permanent solution, it can be used for quick and temporary connections. Taping wires can be dangerous and may breach wiring regulations or codes, so it is important to exercise caution when using this method.
If you are connecting two electric cords together using electrical tape, it is important to first twist the ends of the wires together. This creates a solid conductive metal bridge between the two parts. Once the wires are twisted together, lay the twisted portion on a strip of electrical tape. Wrap the tape tightly around the wires 5-6 times, ensuring that all the wire is covered. Give the connection a tug to make sure it is strong.
It is important to note that electrical tape may not be a long-lasting solution, as it can come off over time and leave connections exposed. This can create a risk of electrical shock or fire hazards. Therefore, it is recommended to use electrical tape in conjunction with other methods, such as soldering or heat shrink tubing, for a more secure and permanent connection.
To ensure safety, it is always best to consult a professional or refer to reliable sources for detailed instructions on how to properly attach two electric cords together using electrical tape or other recommended methods.
Overall, while electrical tape can be used for temporary connections, it is important to prioritize safety and consider using alternative methods for more secure and long-lasting results.

Soldering wires together
Step 1: Prepare the Wires
Start by stripping about 1 inch (2.5 cm) of insulation from the end of each wire using a wire stripper or a utility knife. You can get wire strippers from your local hardware store. This step is crucial as it exposes the conductive part of the wires, allowing them to be joined securely.
Step 2: Twist and Wrap the Wires
Once the wires are stripped, twist the exposed ends together to combine them. Line up the centers of the wires to form an "X" shape, then bend one wire and twist it tightly around the other. Repeat with the other wire, ensuring your splice looks even on both sides. This twisting provides a firm mechanical connection between the wires.
Additionally, you can wrap one wire around the other, being careful to leave enough exposed metal above the sheath for the other wire to be wrapped around it. This wrapping technique ensures that the wires themselves bear the strain if they are pulled on, rather than relying solely on the solder to hold them together.
Step 3: Tin the Wires (Optional)
Before soldering, you can tin the wires to make the process easier. Add a small amount of solder to the filaments of each wire using your soldering iron. This helps the solder flow better during the actual soldering process and reduces the risk of damaging nearby components or melting through the wire shielding.
Step 4: Soldering
Put on a pair of safety glasses to protect your eyes from any splatter. Turn on your soldering iron and allow it to heat up completely. Melt some solder onto the tip of the iron to prevent oxidation and ensure a smooth soldering process.
Now, apply solder to the twisted or wrapped section of the wires, ensuring an even distribution. Be careful not to use too much solder, as it can make the wires stiff and reduce their flexibility.
Step 5: Finish and Protect
After soldering, cover the exposed wires to seal and waterproof them. This step ensures that your connection is protected from the elements and any potential electrical hazards.
By following these steps, you will have successfully soldered two wires together, creating a strong and long-lasting electrical connection.

Alligator clips
To use an alligator clip, first open the jaws by pinching the back and attach the clip to the battery or electrical device. Make sure that the clip has contact with a metal surface. Then, close the clamp by squeezing it shut until it locks into place. This will form an electrical connection.

Hot glue
To attach two electrical cords together using hot glue, you will need a hot glue gun and glue sticks, which can be purchased at your local hobby store. You will also need two wires with twisted ends. Ensure that you are using a hot glue gun with exchangeable nozzles so that you can adjust the glue flow as needed.
First, lay the two cords on a flat surface, such as a table, so they are end-to-end. Then, heat up your glue gun and hold it perpendicular to the twisted wires. Squeeze a glob of glue onto the wires and use the nozzle of the glue gun or a pencil to swirl the glue around them. Be careful not to touch the hot glue or the tip of the gun to the wires. Swirling the glue will create a better bond than simply leaving a glob of glue.
Make sure that the entire part of the stripped wire is coated in hot glue, then let the glue cool. Once the glue has cooled, your connection should be strong and hold together when a small tug is applied. If you need to adjust or remove the cable, you can warm the glue with a hot air gun.

Frequently asked questions
Here are some simple ways to join two electric cords without soldering:
- Alligator Clip Method: Use alligator clips to snap into place over the stripped ends of two wires held parallel to each other.
- Electrical Tape Method: Twist the ends of the wires together and wrap them tightly with electrical tape 5-6 times.
- Hot Glue Method: Use a hot glue gun to apply glue to the twisted ends of the wires. This method also provides insulation.
Some more complex methods that require additional tools include:
- Crimping Method: Insert stripped wires into a crimp or thin metal tubing, then use a crimping tool to squeeze the crimp into a "U" shape.
- Scotchlok Connectors: Use a pair of pliers to squeeze the connector, causing the metal piece to cut through the insulation of both wires and make the connection.
- Wago Connectors: Twist the wires back and forth while pulling them firmly into the connector.
Attaching electric cords together can maximize the length of your cords and save you time and money by providing a longer reach from the outlet plug.
Always ensure that you use the correct size and type of connector for your wires to avoid any damage to the copper wire inside. Insulation is also critical to prevent unintentional disconnections and power loss. Heat-shrink tubing or electrical tape can be used to provide insulation and protect the connection.
Yes, products like the Jokari Extension Cord Connector are designed to join two electric cords and keep them securely connected. These connectors are quick and easy to use, preventing unintentional disconnections and power loss when using power tools or electrical devices.
