NOTE: When a stranded conductor is soldered, the soldered portion of the conductor becomes a solid strand conductor, and flexing can cause the conductor to break at the end of the solder joint unless adequate additional support is provided. If soldered, the connection shall be so located or supported as to minimize flexing of the conductor where the solder changes the flexible conductor into a solid conductor.ĮXCEPTION: Battery lugs with a solder contact length of not less than 1.5 times the diameter of the conductor. In my experience, it's not worth it when quality heatshrink crimp connectors are so good and so much more convenient.įor reference, ABYC E-11 is the electrical code for boats which share some characteristics with cars as far as motion and vibration go:ġ1.14.5.7 Solder shall not be the sole means of mechanical connection in any circuit. You can do it, you just also need another form of mechanical connection so the soldered joint has no strain on it. I wonder is there is a better solution for such problems? This feels like a kinda hacky way to get things done. But for the other side the diameter is to small for the connector so I removed more insulation from the wire and fold the wire over to get another "virtual" 2 mm² wire so the crimp connector holds the cable tight. I twist them together to get a "virtual" 2 mm² cable. For the side with the two cables there is no problem. If I had to join three wires together, like 3x 1 mm² cables I used a crimp connector for 1,5-2,5 mm² cables. Choose from our selection of three-way connectors, including stainless steel pipe and pipe fittings, brass and bronze pipe and pipe fittings, and more. Unfortunately this is not an option for DIY cause those devices are quite expensive.įor all my jobs I used crimp butt connectors. Low Voltage Wire Connectors, Kalolary 20 Pack 2 Pin 3/2 Way Wire Connector, Universal Compact Wire T Tap I Type Connectors Electrical Wire Connection Self-Stripping Quick Splice Fits 20-24 AWG 4. Offering specialty wire terminals including: tap splices, piggy back connectors, 3 & 4 way connectors and double male coupler terminals for copper wire. For those joints car manufactures uses ultrasonic welding. Sold by Brightfour US and ships from Amazon Fulfillment. For example if you want to modify your doors wiring loom you will find often a common positiv or negativ connection coming from the car chassis and this wire splices into, for example 5 smaller cables to alle the different electronics in the door. Brightfour Low Voltage Wire Connector, Quick Wire Splice Connector, 3 Way T Tap Solderless Wire Connectors, Ideal for LED Lighting, and Automotive, Fit 24-18 AWG Wires 12 Pack. Sometimes, when you are retrofitting electronics to your car you will have to splice into existing wires. This is a solid solution for joining two wires but what about three or more wires? Personally I like the crimp butt connectors with heat shrink and glue inside of them to get a waterproof seal around the cable. I looked around the internet and found several "solutions" for this problem (crimp, soldering, tape, fancy twisting methods.
