Welding method of audio cable

Lotus head audio cable welding method: Divide the audio cable into two, weld the left and right channels and cover them with heat shrink tubes for protection.

1. The types of audio cables can be divided into two categories, "audio electrical signal cables" and "audio optical signal cables", among which "audio electrical signal cables" are mostly of types, including 3.5mm male-to-male audio cables and 3.5mm male-to-male audio cables. To female audio extension cable, 3.5mm to RCA audio cable, double lotus head (RCA) audio cable, car AUX audio cable, 3.5mm to 6.35mm stage audio cable, card interface audio cable, single crystal copper fever audio cable, the same Axis audio cable and more.

2. Tools needed to make RCA plugs 1. An ordinary soldering iron, a pair of scissors or wire strippers, a pair of needle-nose pliers, a pair of solder wires, and a number of solder wires (the amount used to make a wire is about 5CM-10CM) RCA Materials needed for plug making Two RCA plugs (to make one wire) OFC oxygen-free copper two-core audio cable one (length depends on needs) Tools and materials The RCA plug is divided into two parts, the plug core and the outer casing The double-ended RCA cable is not divided into male and female. When connecting the equipment, the first step is to put on the sheath and connect it according to the direction mark on the wire. Peel off the 2CM sheath (not standard, but you can see the three main wires after peeling off (generally, the positive wire is too long to avoid wasting the wire) extremely red, and the negative electrode is white). The shielded wires are twisted together (if the two ends are mostly RCA, the positive and negative poles can also be dropped. This is to be compatible with soldering methods such as RCA-XLR RCA-TRS).

3. Tighten it, twist it into a strand, and strip off the wire end of the positive electrode, it does not need to be too long. The shielded wire can be cut short by about 0.5cm, and the length is about half of the positive electrode. Take out the RCA core to separate the line card, don't break the card too much, you can put the line in. Put a heat shrink tube on the tin positive pole of the RCA and press the shielded wire to the RCA grounding plate, try to solder it with a soldering iron, the time does not It needs to be too long, so as not to burn the wire away from the positive terminal, and press the positive terminal to the center terminal. Then push the heat-shrinkable tube forward, try to hold up all the terminals, and then shrink to cover the outer casing, and the welding of the RCA plug is completed.
