Electrical systems have grown in importance in the recent history of automobile design. Modern automobiles are heavily wired and microprocessor-controlled, necessitating an increased demand for more dependable wiring and connectors.
The components of a typical automotive electrical system are depicted below. Most of the components in this system require connectors to communicate with one another. Automotive electrical connectors are used specifically in vehicle electrical systems.
Automotive connectors are classified in several ways, including by electrical system components.
Audio connectors, for example, are used to power and connect a vehicle's audio system. According to ISO standard 10487, there are four types of audio connectors:
1. Power connectors (A) connect the vehicle's head unit to a power supply, on/off switches, and specialized components like antennas and speed-dependent volume controls.
2. B-group connectors are used to connect speakers located throughout the vehicle.
3. C-group connectors are optional and are used to connect specialized peripherals like remote controls, CD decks, and external amplifiers.
4. D-group connectors are optional and are commonly used to connect satellite navigation systems.
Automotive connectors can come in a variety of shapes and sizes:
1. Sealed connectors, which account for the vast majority of automotive connectors, are multi-pin devices. Sealing prevents contaminants from entering the environment.
2. Wire terminals are used to connect unsoldered wires.
3. Components are connected to computer circuit boards via wire-to-board connectors.
4. Board-to-board connectors link two circuit boards together.
5. Wire-to-wire connectors connect two wire-terminated cables.
