Wire harness processing drawing design skills

  In the customer's drawing design, the wire harness processing engineering technical team mainly includes: product dimension drawing, product BOM detail and dosage, mechanical properties and physical properties of the raw materials of the product. The mechanical properties and physical properties of the wire harness processing mainly include the bending times of the raw materials, the terminal tensile test and the resistance of the raw materials. The bending times and the terminal tensile test can refer to the Dadaokang wire harness processing documents. Da Dao Kang wire harness processing talks about how to design the resistance value of raw materials in the drawing design.


In the wire harness processing drawing design, the wire impedance is mainly based on the resistivity, cross-sectional area and length of the conductor and the insulator, and the insulation resistance and the on-resistance are calculated according to the resistance law R=ΡL/S.
  1. The wire material is generally divided into bare copper and tinned copper wire. According to the constant temperature of 20 °C, the resistivity of bare copper is 0.0178 Ω*mm2/m, and the resistivity of tinned copper wire is 0.0172 Ω*mm2/m.
  2.the wire is generally made of PVC material, the resistivity is 108Ω*m.
  3. Calculate the on-resistance and insulation resistance of the wire according to the conductor area processed by the customer.

  4. The terminal harness technical team must clarify the tension of the terminal during the design drawing process.
