Selection Principle Of Automotive Wiring Harness Connectors

Automotive wiring harness connectors are important connecting components for the various connection points of automotive circuits. Its quality is good or bad, directly affecting the transmission of electricity or signals. Therefore, the selection of a suitable connector is of great significance for ensuring the reliability of the vehicle line. According to the basic performance of the connector, the selection of the connector needs to be considered in terms of electrical performance and mechanical properties. Our article mainly discusses the selection conditions of its electrical performance. Keep reading for more information.

Electrical performance

The connector is the standard component that connects the electrical circuit of the cars and trucks. For that reason, the electric specifications of the connector itself are the first considerations when selecting the connector. Electrical efficiency is separated into 3 elements: rated voltage, get in touch with resistance, and also insulation performance.

1. rated voltage

The rated voltage is also called the functioning voltage and the ranked voltage of the connector. The rated voltage offered by the connector supplier is the optimum operating voltage of the connector. For reduced voltage connectors, the voltage provided by the supplier is typically 50 V. In general, the connector functions well listed below the ranked voltage.

The influencing aspects are the insulator material used in the connector, the spacing in between the conductive terminals, and so on.

2. insulation efficiency

The insulation efficiency of the connector is likewise an important electric building. The criteria showing the insulation residential properties of the insulation resistance as well as dielectric stamina are some of the most fundamental electrical specifications to make certain the dependable operation of the connector.

The influencing aspects are product, temperature level, moisture, chemical examination solution, dust, etc 3. get in touch with the resistance

The contact resistance directly impacts the signal transmission and electrical connection of various electric equipment of the vehicle as well as influences the functioning security and also dependability of each electric device.

The influencing factors are terminal material, terminal get in touch with user interface geometry, incurable positive pressure, as well as terminal contact user interface surface state.

Tips during installation

Before the installation of seals must ensure that there are no impurities and cracks in the sealing groove, the seal groove, and the surface of the seal coated with operation oil.

Gradually install seals in sequence.

Avoid sharp edges and centralize seals during installation to avoid distortion and deflection.

If the split groove, finally tight pressure cover.
