Cable selection needs to be matched: vehicle cable selection and matching are divided into cable current carrying matching and cable and connector sealing matching. Regarding cable current carrying, each OEM has special electrical engineers for matching design, which will not be explained here.
Seal matching: The connector and cable seal rely on the elastic compression of the rubber seal to provide contact pressure between the two, so as to achieve reliable protection performance, such as IP67; according to the calculation, the specific contact pressure is achieved by the specific compression of the seal, and so on Introduced, if reliable protection is required, the sealing protection of the connector has specific size requirements for the cable at the beginning of the design;
For the same current-carrying cross-section, the cable can have different outer diameters, such as shielded cable and unshielded cable, national standard cable and LV216 standard cable. When selecting the connector, special attention should be paid to the specifications of the adapter cable to prevent the connector from sealing failure.
