Precautions for connecting electronic wires to automotive wiring harnesses

In the harness processing and production process there are some relatively common connection lines, electronic wires, automotive harness wire connection degree requires us to pay attention to some relevant matters: 1. Terminals and wire connection: winding voyage terminals, must be wrapped around 1 to 2 laps; cup-shaped terminals along the side of the longer inner wall tightly connected; cylindrical terminals greater than 1.5 turns, the threaded end must be wrapped around the terminals; barrel column-shaped indicated terminals, the diameter of the wire is generally less than 0.5 mm of the wire is also must be hooked on the terminal; perforated terminals, the wire must be hooked on the terminal, the diameter is less than 0.5 mm, the wire must be bent into an s-shape; hooked, leakage part of the size of 0.5-1.5 mm, the side can not be bent, the wire must be tightly connected with the terminals, the insulation can not be entangled.2. Connections between the wire and the wire data: Lap: Lap length requirement is greater than 3 mm. automotive wiring harness automotive circuit of the network body, no wiring harness also does not exist in the automotive circuit. Wiring harness refers to the copper punched and made of contact parts terminals (connectors) and wire and cable crimping, and then outside the plastic pressure insulator or additional metal shell, etc., to wire harness bundle to form a connected circuit components. Wiring harness plant from the functional points, there are two kinds of power lines to carry the power to drive the actuator (actuator) and signal lines to transmit the sensor input instructions. As people's comfort, economy, safety requirements continue to improve, the types of electronic products on the car is also increasing, the automotive wiring harness is more and more complex, the failure rate of its wiring harness is also increased accordingly; spiral connection: a wire must be wound around the other wire spiral, the external to set up the protection of insulated heat-shrinkable casing.
