Production and testing process of energy storage high voltage wiring harness

Energy storage wiring harnesses play an important role in signal and data transmission and power supply in the entire energy storage industry chain, and are an indispensable and important product in the market. Now we have a detailed understanding of the production and testing processes of energy storage high-voltage wiring harnesses. Bar.

1. Incoming material inspection:

 Conduct environmental protection testing on all raw materials of the wiring harness to ensure that all raw materials comply with ROHS standards and do not contain harmful substances such as lead (Pb), mercury (Hg), cadmium (Cd), brominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). .

2. Line delivery:

Place the wire to be processed on the wire feeder and fix it. Be careful not to scratch the surface of the wire.

3. Cutting line:

Use a computerized wire cutter to cut the wire to the required length. Be careful not to cut the surface of the wire, not to cut the copper wire, and the error of peeling length should not exceed ±1mm.

4. Wire stripping:

According to the SOP requirements, use a pneumatic stripper to strip the insulation of the corresponding length of the wire at the joint. It is required not to crush the surface; the error of peeling length should not exceed ±1mm.

5. Twist the wire:

Use a twisting machine to arrange and twist the conductors at the joint. Be careful not to scratch the surface of the wire; the copper wire must be tightened to prevent loose wires.

6. Riveting terminal:

 Use a terminal machine to rivete the conductor at the joint and the plug terminal. It is required that the terminal is not allowed to deform; it must meet the requirements of tensile force, riveting height and width.

7. Product assembly:

Use an electric screwdriver to assemble the plastic plug housing. It is required that the screws should not be exposed to the surface of the plastic shell; the torque required by the product must be met.

8. Continuity test:

Conduct a continuity test of the wiring harness with a continuity tester. It is required that no short circuit, open circuit, wrong wiring, poor contact, poor insulation and other phenomena are allowed.

9. Packing and sealing:

Use the sealing machine and the baling machine to seal the finished wire harness and put it into a carton. It is required that the seal should be flat; the packing tape should be tightly wrapped in the carton, and it is not allowed to fall off.

The plug-in series terminal plug adopts the principle of the lifting cylinder to realize the connection function, that is, when the screw is tightened, it is kept under the support of the plastic body, and the wire is driven up by the pressure line of the lifting cylinder.
