With tail clip, the tail clip needs to be stuck between the connector and the wrapping material. Generally, the length of the head is the loss inside the tail clip and the connector.
In summary, whether the head size is the internal loss of the connector and the back clip directly affects the branch length. Under normal circumstances, for connectors with less than 8 holes, the loss of wire length with tail clips does not exceed 5cm. When the length of the head is less than 5cm, it is regarded as the internal loss of the connector, and there is no need to increase the branch length.
When the wire is assembled into a wire harness product, there should be no tension. When a single wire is stressed, it should be in a natural, non-stretched and folded state. Therefore, the length calculated only by the drawing does not meet the actual processing needs and should be lengthened appropriately. In addition, the processing of wire harnesses at this stage is mostly in the form of manual production, and it is inevitable that there will be a loss of length. Therefore, the length of the down line should be increased by an appropriate margin on the basis of the length of the drawing.
