1. Wrap the terminal, which must be wound 1 or 2 times;

2. Cup type terminal must be closely connected along one side of the long inner wall;

3. Cylindrical terminal, more than 1.5 turns, wire must be wound at the terminal;

4. Cylinder type terminal, the wire with diameter less than 0.5mm must be hooked up to the terminal;

5. For the perforated terminal, the wire head must be hooked to the terminal, the diameter is less than 0.5mm, and the wire head must be bent into S shape;

6. Hook connection, outer leakage part size between 0.5 and 1.5mm, side can not be bent, the wire must be closely connected with the terminal, can not wind insulation layer;

Connection between conductors

1. Lapping: the length of lapping is required to be greater than 3mm, the connection method is mechanically weak, and the insulation heat shrinkable sleeve shall be covered externally for protection;

2. Helical connection: one wire must be spirally wound around another wire, and the outside should be protected by insulated heat-shrinkable sleeve
