Matters needing attention during wire harness processing

Connection aspect of terminal and electronic wire:

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 on another wire, and the outside should be protected by insulated heat-shrinkable sleeve;

Second increased the difficulty with the development of global industry, in the process of laying a growing number of environmental requirements must be outside diameter is small, high voltage cable products in the process of laying there need to consider the gaps, so you can send out the heat generated by the electric wire electric cable after electrify, too thick sheath thickness will increase the difficulty of laying, so the thickness of sheath requirements strictly comply with relevant standards, otherwise unable to protect the wire and cable.
