Electrical system requirements

1. Reasonably set the number of holes in the inner connector, 15%-30%of the design balance

Under normal circumstances, in order to meet the entire vehicle planning of subsequent model configuration adjustments or increased function, select a cover with a slightly larger number of holes than the circuit. The pores of the protective cover are usually about 15%-30%. Of course, this proportion needs to be appropriately adjusted according to the configuration plan of the vehicle. For internal connections that determine the number of circuits in the life cycle of the entire vehicle, the hole can be reserved without changes.

2. The wire diameter and current strength of the internal connection adaptation

The width of the condenstes of the sheath adaptation determines the range of the current to adapt to the sheath. The current that can be carried by the terminals of different widths is generally as follows: the terminal width specifications of about 1.0 series; the specifications of about 20A of the specification 2.2 or 3 series; the specifications of about 30A; the specifications of about 45A; specifications of 7.8 or 9.5 series About 60A.

On the one hand, on the one hand, whether the terminal that can be adapted by the shentholes should carry the corresponding current strength, and the wire diameter range of the terminal adaptation should also be considered. Under the premise of satisfying the load current, try to choose a small cover.

Choosing a cover with too large width of the terminal causes waste in terms of cost, and the demand for installation space will also increase. From the perspective of processing, it is not conducive to the terminal insertion of the fine wire.

Selecting a cover with a small width of the terminal, the current carriers of the terminal can not meet the requirements, which will cause the terminal to overheat the connector and severely cause ablation. If the large current and small currents in the loop connect to the internal connection are large, and a single -specification terminal cannot meet the requirements of the usage, you should consider using a composite insert or two independent internal connectors separately.
