The Plug Portion Includes A Generally Cylindrical Outer Terminal Electrically Coupled

The power cord may be either permanently or removably coupled to the housing of the hand-held electrical device

. Some types of removably coupled power cords havea tendency to detach during operation of the hand-held electrical device. Although a number of arrangements for selectively retaining such power cords are known, a new arrangement that improves the overall usability of the hand-held electrical devicewould be welcomed by those in the art.

The power cord includes an enlarged tip portion that provides axialresistance against removal of the power cord from a housing of the hand-held electrical device when the power cord is operatively coupled to the housing of the hand-held electrical device.

A receptacle is electrically coupled to the electrical component and has a body portion, a male terminal, and a detent terminal. The body portion includes a first end portion located adjacent the aperture, a second end portion, and a recessportion extending from the first end portion towards the second end portion. The male terminal has a male terminal portion located in the recess and extending in a direction from the second end portion toward the first end portion.

The plug portion includes a generally cylindrical outer terminal electrically coupled to the first electrical conduit and defining a first diameter, a female terminal electrically coupled tothe second electrical conduit and located radially inward of the outer terminal, and an insulator portion that electrically insulates the outer terminal from the female terminal and includes a tip portion that extends axially beyond the outer terminal ina direction away from the cord portion and defines a second diameter that is larger than the first diameter.

The body portion includes a first end portion located adjacent the aperture, a second end portion, and a recessportion extending from the first end portion towards the second end portion and having a generally cylindrical portion defining a receptacle diameter and a detent portion intersecting the generally cylindrical portion. The male terminal has a maleterminal portion substantially centered in the generally cylindrical portion and extending in a direction from the second end portion toward the first end portion.

The plug portion includes a generally cylindrical outer terminal electrically coupled to the first electrical conduit and defining an outer terminal diameter, a female terminal electrically coupledto the second electrical conduit and located radially inward of the outer terminal, and an insulator portion formed of nylon that electrically insulates the outer terminal from the female terminal and includes a generally cylindrical tip portion thatextends axially beyond the outer terminal in a direction away from the cord portion and defines a tip portion diameter that is larger than the outer terminal diameter and substantially equal to the receptacle diameter so the tip portion provides axialresistance against the removal of the power cord from the receptacle when the power cord is operatively coupled to the receptacle.

A direct current motor is positioned in the housing and is drivingly connected to the blade set.The body portion includes a first end portion located adjacent the aperture, a second end portion, and a recess portion extending from the first end portion towards the second end portion and having a generally cylindrical portion defining areceptacle diameter and a detent portion intersecting the generally cylindrical portion.

The male terminal has a portion substantially centered in the generally cylindrical portion and extending in a direction from the second end portion toward thefirst end portion. A power cord having a cord portion and a plug portion is configured to provide direct current voltage to the direct current motor when a portion of the power cord isinserted through the aperture to operatively couple the power cord to the receptacle. The cord portion includes first and second electrical conduits.
