Car terminals are used to connect fuses, battery terminals, and vehicle sensors. They are found in cars, trucks, motorcycles, RVS, SUVs and engineering vehicles, as well as electric vehicles.

Today's cars contain about a mile of wire and thousands of electrical connections. These connections power and control the vehicle and its accessories, including safety and infotainment functions. They connect the battery and the vehicle's electrical system to provide efficient power transmission and maintain the integrity of the circuit. They ensure that these connections are strong enough to stay safe even when subjected to harsh environmental conditions such as shock, vibration and extreme temperatures. Automotive terminals can be board-to-board or wire-to-wire connectors, and they come in a variety of styles and various connection types.

Heilind Electronics offers TE Connectivity's wide range of automotive terminals.

Board-to-board (BTB) connectors allow the transmission of signals and power between different components of the vehicle.

Wire-to-wire automotive connectors support the connection of two end wires. They are essential for vehicle maintenance and repair, especially for the repair of the vehicle's electrical system.

Common types of automotive terminals

•  Plug terminal: used for the connection of plugs and sockets, commonly seen in sensors, control units, etc.
• Crimping terminal: Secure the end of the wire using the crimping tool for the wiring harness and patch board.
• Ring terminal: Used for bolt or screw fixation, commonly used in battery and ground connection.
• Chip terminals: Used to connect switches, relays and other devices.

Application scenario of automobile terminals

• Engine control system: connect sensors, actuators, etc.
• Body electrical system: for lighting, sound, air conditioning, etc.
• Chassis control system: connected to ABS, ESP and other systems.

Auto terminal selection points

• Current and voltage: Select the appropriate terminals according to electrical requirements.
• Environmental conditions: consider temperature, humidity and other factors, choose corrosion resistant materials.
• Installation mode: Select an appropriate installation type based on the installation space and mode.

Automotive terminals play an important role in the electrical system, and the correct selection and maintenance help to ensure the reliability of the vehicle electrical system.
