## Abstract

A detachable plug, including a main body, including a first section, and a second section detachably connected to at least a portion of the first section to detach from the first section in response to an application of force exceeding a predetermined level of separation force, a first connector disposed on at least a portion of the first section to removably connect to at least a portion of a motor vehicle, and a second connector disposed on at least a portion of the second section to removably connect to at least a portion of a trailer.

## Claims

### Claim 1

A detachable plug, comprising:
a main body, comprising:
a first section, and
a second section detachably connected to at least a portion of the first section to detach from the first section in response to an application of force exceeding a predetermined level of separation force, wherein the application of force is provided in a first direction toward the first section that is linearly parallel and opposite to a second direction toward the second section;
a first connector disposed on at least a portion of the first section to removably connect to at least a portion of a motor vehicle;
a second connector disposed on at least a portion of the second section to removably connect to at least a portion of a trailer; and
a locking clip springingly disposed on at least a portion of at least one of the first section and the second section to lock the first section to the second section in response to moving the locking clip from extended away from the first section and the second section in a first position to at least partially retracted toward the first section and the second section in a second position, and unlock the first section from the second section in response to moving the locking clip from retracted toward the first section and the second section in the second position to extended away from the first section and the second section in the first position, wherein the locking clip is unlocked in response to the application of force.

### Claim 2 (depends on 1)

The detachable plug of claim 1, further comprising:
a plurality of connecting wires disposed within at least a portion of at least one the first section and the second section to send power received by the first connector to the second connector.

### Claim 3 (depends on 2)

The detachable plug of claim 2, wherein the plurality of connecting wires send power received by the first connector to the second connector in response to locking the locking clip, and prevent power from being sent from the first connector to the second connector while the locking clip remains unlocked.

### Claim 4 (depends on 1)

The detachable plug of claim 1, wherein the first connector
comprises: a first body; and
a male end disposed on at least a portion of the first body to removably connect to at least a portion of the motor vehicle.

### Claim 5 (depends on 1)

The detachable plug of claim 1, wherein the second connector
comprises: a second body; and
a female end disposed on at least a portion of the second body to removably connect to at least a portion of the trailer.

### Claim 6 (depends on 5)

The detachable plug of claim 5, wherein the second connector further comprises:
a barrier pivotally disposed on at least a portion of the female end to move from closed over the female end in a first position to at least partially opened away from the female end in a second position, and move from opened away from the female end in the second position to closed over the female end in the first position.
