Släpvagnskontakten

Släpvagnskontakten, often referred to as a trailer connector or plug, is a standardized electrical connector used to connect a trailer's lighting and electrical system to the towing vehicle. This allows for the transmission of power from the vehicle to the trailer's lights, such as brake lights, turn signals, taillights, and sometimes reverse lights and hazard lights. In some cases, the connector also provides power for auxiliary functions on the trailer, like charging a battery or operating interior lights.

The design and pin configuration of trailer connectors vary by region and application. In Europe, the 7-pin connector (Type 13-pin) is common for standard trailers, providing basic lighting functions. A 13-pin connector (Type 13-pin) is also widely used, offering additional circuits for features like reverse lights, interior lighting, and battery charging. In North America, 4-pin, 5-pin, 6-pin, and 7-pin connectors are prevalent, with different pin assignments for various functions.

Proper connection and maintenance of the trailer connector are crucial for road safety. A secure connection ensures that all trailer lights function correctly, which is essential for communicating braking, turning, and other intentions to other road users. Corrosion, damage, or loose connections can lead to malfunctioning lights, potentially resulting in traffic violations or accidents. Trailer connectors are typically made of robust materials to withstand environmental exposure.
