Can pass through connectors be used to connect automotive electronic systems?

Pass through connectors can be used for connecting automotive electronic systems, but they must comply with the specialized standards and environmental adaptability requirements of the automotive industry. The following is a point by point introduction:

1. Used for wire harness docking and extension
▸Pass through connectors are widely used in automotive electronic systems to connect or extend onboard wiring harnesses.
▸Commonly used for signal and power connections between electronic modules such as instruments, power supplies, sensors, lighting systems, audio systems, navigation, etc.

2. Rich types, adaptable to different interfaces
▸The types of straight connectors used in automobiles include:
▸Plug-in connector
▸Snap on straight through connector
▸Waterproof pass through connector (such as used in engine compartment, chassis)
▸Multi core pass through plug (such as used for CAN bus, LIN bus communication)

3. Used for signal and low-voltage power transmission
▸Most automotive electronic systems operate in 12V/24V DC systems, and pass through connectors are commonly used in these low-voltage power or signal channels.
▸For example:
▸Docking between OBD interface, camera module, control module and main harness
▸Signal connection between ECU (Electronic Control Unit) and submodules

4. Possess good seismic resistance and stability
▸There are continuous vibrations, temperature changes, and high humidity issues in the automotive environment, and pass through connectors need to have the following capabilities:
▸Anti vibration and non loosening
▸Reliable contact without interruption of electricity
▸Resistant to high and low temperatures (such as -40 ° C to 125 ° C)
▸Corrosion resistance (such as salt spray and oil resistance)

5. Support rapid assembly and modular maintenance
▸The straight through connector facilitates quick insertion and replacement of modules, improving the maintainability of automotive electronic systems.
▸Facilitating standardized assembly by automobile manufacturers on assembly lines.

6. Must meet the standards of vehicle regulations
▸The pass through connectors used must comply with relevant standards, such as:
▸ISO 16750 (Electrical Environment for Road Vehicles)
▸USCAR (US Automotive Connector Standard)
▸AEC-Q200 (Reliability Standard for Automotive Electronic Components)
▸Require high reliability, low contact resistance, and long-term stability.

7. Precautions
▸Interface compatibility: Different vehicle models/manufacturers have different interface standards and must accurately match terminal types.
▸Error proof design: Many car connectors have foolproof structures to avoid connecting in the wrong pass throughion.
▸Tightness of connection: There should be a buckle or locking mechanism to prevent loosening.
