Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function.
Automotive connector form and structure is ever-changing, which is mainly composed of four basic structural components, namely: contact, shell (depending on the species), insulator, accessories. In the industry is usually also known as sheath, connector, plastic shell.

About Automotive Connectors
Electrical signals and power signals can be connected together through cables so that all kinds of information can be transmitted to different devices such as engines, sensors, displays and operating systems.
Automotive connectors play an extremely important role in the automotive electrical system, it can ensure the stability, reliability and safety of the transmission of various electrical signals, thus ensuring the normal operation of the entire vehicle system and safe driving.
The role of automotive connectors
1. Signal transmission: Automotive connectors can transmit a variety of electrical signals (such as voltage, current, data, etc.) to the appropriate device to achieve the exchange of information and functional control of various parts of the vehicle.
2. Protection: automotive connectors will come with some internal protective measures, such as waterproof, dustproof, shockproof, etc., can effectively protect the electrical lines from external interference and environmental impact.
3. Easy maintenance: automotive connectors are plug-and-play design, which can be easily disassembled and installed, thus bringing great convenience for automotive repair and maintenance.
4. Improve vehicle safety: automotive connectors will be built-in protection circuits, such as short-circuit protection, overload protection, etc., can automatically cut off the power supply, so as to effectively avoid the dangerous situation caused by electrical failure.
put at the end
With the continuous improvement of automotive electronics, automotive connectors have been more and more widely used and promoted, it is not only used in traditional fuel vehicles, but also widely used in new energy vehicles, intelligent vehicles and other types of vehicles, becoming an indispensable and important part of the modern automotive electrical system. At the same time, the quality and stability of automotive connectors for vehicle performance and safety of the impact of people’s attention, therefore, the research and development and production of automotive connectors has gradually developed into an important science and technology industry.
