Precautions during wire harness processing

Terminals and electronic wire connection aspects: 1. winding terminals, must be wound 1 to 2 turns; 2. cup terminals, must be tightly connected along the longer side of the inner wall; 3. column terminals, greater than 1.5 turns, the wire must be wrapped around the terminals; 4. Barrel column terminals, the diameter of less than 0.5mm of the wire must be hooked to the terminals; 5. pierced terminals, the wire must be hooked to the terminal, the diameter of less than 0.5mm, wire must be bent into a S-shaped; 6. hook connection, leakage part size between 0.5 and 1.5mm, the side must be bent, the wire must be tightly connected to the terminal, and not bended into a S-shaped; 6. hook connection, leakage part size between 0.5 and 1.5mm, the wire must be bended into an S-shaped; 6. Diameter less than 0.5mm, the wire must be bent into S-shaped; 6. hook connection, the leakage part of the size of 0.5 to 1.5mm between the sides can not be bent, the wire must be tightly connected to the terminal, can not be entangled in the insulating layer; wire and wire connection: 1. Lap: lap the length of the requirements of more than 3mm, the method of this connection is mechanically weak, the external set of insulating heat-shrinkable tubing to protect; 2. Spiral connection: a wire must be spiral winding in another wire, the external set of insulation heat shrink tubing protection;.

Secondly, increase the difficulty of the laying process with the development of global industry, more and more environmental requirements of high-voltage cable products must be done to achieve a small OD, in the process of laying needs to be considered to leave a gap, so as to radiate off the wire and cable after the heat generated by the power, the sheath thickness is too thick will increase the difficulty of the laying process, so the thickness of the sheath required to strictly comply with the relevant standards, otherwise it can not play a role in protecting the wire and cable! Role.
