It is conventional to provide electrical power to the lights of a trailer via wiring harnesses on the draft vehicle and the trailer which have mating terminal end connectors that are detachably coupled together. These connectors each have one or more electrically conductive male pin terminals and one or more electrically conductive socket terminals which receive the complimentary formed, female and male electrically conductive terminals on the other connector. When the draft vehicle is not coupled to the trailer, and the wiring harnesses are not coupled together, the harnesses are typically left hanging from either the draft vehicle or the trailer and exposed to the elements. Sometimes dirt, snow, ice, or moisture fill the electrically conductive socket members and thus, cannot be used until cleaned. If the terminals are exposed to moist environments corrosion of the connectors can lead to complete failure of the terminal conductive surfaces. This is particularly frustrating to the trailer user. Additionally, the uncoupled connector ends on the draft vehicle or trailer will sometimes drag on the ground and become damaged. Accordingly it is an object of the present invention to provide a new and novel device for securing the trailer wire harness and providing protection; preventing dirt, ice, moisture or other foreign matter from contaminating the trailer light harness coupling members when not in use.
When disconnecting a trailer from a towing vehicle, it would be helpful to provide a device mounted on the trailer in which the male plug of the trailer may be stored when the trailer is not in use. The device should provide a relatively snug fit, with no moving parts, while protecting the electrical plug from exposure to the weather, etc. The device should be constructed of a semi-flexible polyvinylchloride material that is damage resistant in all typical North American temperature extremes.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: The invention relates to a series of individual devices for stowing, protecting, and securing one of multiple embodiments (2-pin, 4-pin, 5-pin, 6-pin, and 7-pin) of trailer light or combined trailer light and braking system wiring harness systems. The invention reduces instances of damage from impact or dragging through the securing of the terminal end connectors of a trailer light or combined trailer light and braking system wiring harness away from the underside of the trailer vehicle coupling tongue. The invention prevents contamination of the trailer light or combined trailer light and braking system wiring harness systems from fouling, dirt, mud, moisture, or any other external elements; while reducing wire harness electrical connector exposure to corrosion causing environments.
It is conventional to provide electrical power to the lights or combined lights and braking systems of a trailer via a conductive wire harness on the draft vehicle and on the trailer which have mating terminal end connectors that are detachably coupled together. These connectors each have one or more electrically conductive male terminals and one or more electrically conductive socket/female terminals, which receive the complementally formed, female and male electrically conductive terminals on the other connector. When the draft vehicle is not coupled to the trailer, and the wiring harnesses are not coupled together, the trailer harnesses are typically left hanging from the trailer coupling tongue. On occasion, water, dirt, snow, dust, or gravel can foul or damage the conductive socket or terminal elements rendering the trailer wire harness unusable until it is repaired, cleaned, or replaced entirely. Additionally an uncoupled trailer wire harness is subject to dragging, crushing, or impact damage, and can result in unserviceability of the trailer wire harness or trailer unit.
Accordingly, it is the object of the present invention (a series of embodiments of storage, protection, and securing connectors for multiple trailer types and uses) to provide a new and novel device for preventing trailer wire harness damage from impact or dragging by providing a method to securely mount the a trailer light or combined trailer light and braking system wiring harness out of the path of the dragging and impact areas of the trailer coupling tongue, and further to securely mount and seal the connector to prevent fouling from dirt, moisture, snow, dust or any external fouling agent when the trailer is not employed by the user.
