The performance of automotive connectors on the safety and reliability of wiring harnesses

The connector is the main component of the wiring harness, and the performance of the connector has an important impact on the safety and reliability of the wiring harness. The design principles for the selection of connectors are as follows: 1.
1. The connector prioritizes the use of double spring-type compression structure of the connector. The use of secondary locking to prevent the terminal from backing out of the sheath; sheath must ensure that the lock; sheath must have a locking structure, can be easily installed and dismantled, the lock.
2. The connector is the main component of the wire harness, the connector performance is good or bad on the safety and reliability of the harness has an important impact can. 
Splicer selection design principles are as follows:
1. The connector prioritizes the use of double spring-type compression structure of the connector. The use of secondary locking to prevent the terminal from backing out of the sheath; sheath must ensure that the lock; sheath must have a locking structure, can be easily installed and dismantled, locking installation in place when it can be clearly felt and heard the ringing sound.
2... Priority is given to the use of hybrid parts for butt sheathing. It is important to take into account the possibility of increasing the number of circuits in the future. In order to ensure that additional circuits can be added in the future, the connector must be pre-positioned. If this is not taken into account, a larger sheath or an additional pair of sheaths may be selected again in the future, which will make installation and fixing difficult. When selecting a harness end sheath to interface with an electrical sheath, select a female sheath for the harness end and a male sheath for the electrical end. It should be noted that in the harness assembly process, the use of male terminals at the harness end may result in terminal bending or even damage. In order to ensure that the connector docking harness contact performance requirements, the choice of the sheath should be able to install the structure of the fixed card.
3. Located in the wet area of the docking sheath, choose a waterproof sheath. Sealing is to waterproof or prevent contamination, the location of the connector in the vicious or wet environment, such as water or corrosive liquids may enter, should choose the sealing of the sheath. Rogue environments include front compartments, wheel covers, chassis, doors, etc. Areas that are easily exposed during user use must be sealed, such as cup holders, gauges, etc. Sealed sheaths must be used where non-liquid contamination is present, e.g., side airbag sheaths and terminals may or may not be affected by seat foam, resulting in loss of gold-plated terminals. Sealed sheaths should be selected where the driver and passenger's rubber is placed, these areas will focus excessive moisture and salt.
4. Sheathing in close proximity to each other on the same harness should be marked or colored to prevent mistakes.
5. Select the connector according to the wire cross-section and overcurrent. Different specifications of the connector can carry the current is generally as follows: 1 series, about 10A; 2.2 or 3 series, about 20A; 4.8 series, about 30A; 6.3 series, about 45A; 7.8 or 9.5 series, about 60A.
6. Airbag, ABS, ECU and other high performance requirements of the connector, give priority to the use of gold-plated parts.
