7-Pin Trailer Connector Socket – Female (Plastic)
This 7-pin trailer connector socket (female coupling) is a key component for linking your trailer’s electrical system to your towing vehicle. It’s typically mounted on the tow vehicle near the hitch, and it receives the plug from the trailer. The 7-Pin Trailer Connector – Female, Plastic ensures reliable transmission of electrical signals to your trailer’s lights so that the indicators, brake lights, tail lights, and other functions operate in unison with your vehicle.
It is made from high-quality plastic with excellent mechanical strength, which will not corrode and can withstand harsh weather conditions. The spring-loaded lid automatically closes when the trailer plug is not inserted, protecting the contacts from dirt and moisture. Inside the socket, there are numbered screw terminals for each of the 7 circuits (e.g., left indicator, right indicator, brake, tail, ground, etc.), making it easy to wire correctly according to the standard.
- Reliable Connection: Provides a stable link with no interruption – the pins align firmly with the corresponding prongs of the male plug. This ensures all your trailer lights function without flicker or loss of connection during travel.
- 12V & 24V Compatible: Designed for the standard 12-volt systems used in passenger vehicles. It can also handle 24V systems (e.g., on trucks) since the connector itself simply carries signals – just ensure proper wiring for the higher voltage.
- Great for Replacement or New Installs: Use it when adding a new tow hitch to a vehicle (if it doesn’t come with a socket pre-installed) or to replace an old or damaged socket on an existing tow setup. Its universal design fits most mounting brackets provided with tow bars.
- Maintenance: It’s advisable to periodically check and clean the contact pins to ensure optimal conductivity. Always close the lid when the socket is not in use to prolong its lifespan and prevent corrosion.
Options for Heavy Use: If you frequently connect and disconnect your trailer or operate in very demanding conditions, you might consider our 7-pin socket with a metal housing for even greater durability. However, this plastic model offers excellent corrosion resistance and is a popular choice due to its lightweight profile and dependable performance.
