1. How to solder a circular connector
1. Remove the insulator, prepare the soldering iron and needle-nosed pliers or tweezers;
2. Place the blade of the soldering iron tip close to the solder joint, and keep the soldering iron at an angle of about 60° to the horizontal plane so that the molten tin can flow smoothly from the soldering iron tip to the solder joint. The time the soldering iron tip stays at the solder joint should be controlled to 1-2 seconds;
3. Make sure that the insulator is not burned, the tin on the solder joint is smooth, burr-free, and there is no cold solder joint, and the definition of the solder wire meets the requirements of the drawing. -
2. What is a circular connector
A circular connector is a cylindrical electronic connector with a circular mating surface. It belongs to the fifth category of the interconnection classification and is mainly used for interconnection between devices. The design of circular connectors includes many types, such as low-frequency circular connectors, RF coaxial connectors and audio connectors, etc., with a wide operating temperature range from -55℃ to +150℃.

3. How to remove the circular plastic terminal head
1. Use scissors or flat-nosed pliers to cut off or remove the outer shell on the circular plastic terminal head to expose the internal wiring part.
2. Use a screwdriver to loosen the screws on the terminal head to remove the terminal head.
3. Gently pull the terminal head by hand to remove it from the wire.
4. If the terminal head is very tight, you can use flat-nosed pliers or pliers to increase the removal force.
5. If you need to replace a new terminal head, you can insert the new terminal head into the wire and tighten the screws to ensure that the wiring is firm. -
4. What are the materials of circular connectors?
1. Metal: It has good mechanical properties and conductivity, and is used for contacts and housings.
2. Plastic: Lightweight, good insulation, and able to resist corrosion by some chemicals, used for insulators and housings.
3. Rubber: Has good elasticity and corrosion resistance, used for waterproofing and sealing.
