​Related manufacturing methods of Automotive wiring harness

Wiring harness engineers need to clarify the manufacturing process of automotive wiring harnesses. Next, let us take a closer look at the related manufacturing methods of automotive wiring harnesses. Here are some answers.

Pre-installed.

The pre-assembly of an Automotive wiring harness refers to the process of installing plugs, plugging rods, positioning clips, etc. into the connector before going online. The method of operation is to first install the positioning clip directly into the card slot of the connector, and usually, it will make a crisp sound when it is in place. At the same time, check whether the positioning clip is damaged. The second is to directly install the plug or the plugging rod into the position required by the visual aid. After that, use the plug tool to squeeze the plug into place. Finally, the pre-installed semi-finished products are loaded into the designated material box.

Assemble the sheath.

Assembling the sheath refers to passing the branch road through the sheath and fixing it to the Automotive wiring harness. The installation requirements of the sheath are as follows: First, the branch shall pass through the sheath and then be inserted into the connector. Second, wear the sheath with a dilator. Expanders can be divided into leather expanding forceps, channels, sheath tooling, etc. The third is to ensure that the direction is correct. Fourth, wrap the tail of the sheath with tape over 3 times. Because a lubricant is sometimes used when the sheath is installed, called a release agent, it is necessary to wrap more tape to fix the sheath. Fifth, for all Automotive wiring harnesses that need to be glued, the sheath must be installed in place. Sixth, after the sheath is expanded and installed, it is necessary to check whether the sheath is intact. The last point is that when installing the sheath, you need to be careful not to damage the terminals. After the branch circuit passes through the sheath, be sure to check the quality of the terminal.

Full inspection.

Full inspection refers to the size inspection and appearance inspection of the Automotive wiring harness after electrical testing. The full inspection is performed based on the size inspection board. The size inspection board is a standard inspection board approved by the Quality Department, which sets the branch size tolerance of the wire harness. All automotive wiring harnesses that meet the tolerances are qualified in size. The inspection method is to operate according to the test reference points on the size inspection board and check the branch size of the Automotive wiring harness in sections. Some parts will be required to be marked after the inspection.
