Vehicle Trailer Connector Magnetic Alignment

The patent replaces the mechanical spring-loaded lid and bead locking mechanism with a magnetic locking system. Magnets are positioned in the connector housing to attract and hold the mating connector through magnetic force, eliminating moving mechanical parts that can jam with dirt or ice. The magnetic field penetrates through the housing walls to provide reliable locking without exposed mechanical components.

The patent eliminates the bayonet-type twist-locking mechanism and replaces it with a magnetic attraction system. The magnets automatically guide and hold the connectors in proper alignment through magnetic attraction, eliminating the need for manual twisting and alignment. Disconnection is simplified by overcoming the magnetic force, which is much easier than forcing apart ice-jammed bayonet couplings.

The patent divides the magnetic locking function into multiple smaller magnets distributed around the connector housing perimeter, rather than using one or two large heavy-duty ring magnets. This segmentation achieves the same total magnetic holding force while using smaller, lighter, and less expensive magnet components that are easier to install and control.

The patent changes the contact geometry from pointed pins requiring high spring force to flat or rounded contact surfaces that distribute pressure more evenly. This parameter change allows for lower spring forces while maintaining reliable electrical contact, reducing the need for expensive non-corrosive materials like stainless steel or gold plating, and allowing the use of standard carbon steel with appropriate coatings.
