Retention components are provided that are configured to retain a first end of an electrical cord in a plugged configuration with an electrical outlet. The retention components have an interior sized to receive the first end therein and include an wire opening having at least one dimension that is smaller than the corresponding dimension of the first end so that the first end cannot pass therethrough. In one form, a wall plate is provided having retention portion configured to retain a first end of an electrical cord, such that with the wall plate secured to a wall or other substrate, the first end of the electrical cord is retained between the wall and the wall plate.

The present invention relates to an extension cord comprising a lead having a first end and a second end. The first end comprises a socket having a cover and the second end comprises a plug. The cover is attached to the socket by a hinged joint possessing a force which resists opening of the cover. The cover comprises a retainer. The present invention also relates to a socket having a cover and a cover of a socket.

An apparatus for use with an item of personal protective equipment, where the item of personal protective equipment includes a sensor configured to detect when the personal protective equipment is being worn properly by the user. The apparatus is housed within a hand-held power tool that includes a power circuit. The apparatus includes an electrical isolation device configured to prevent current flow in at least one conductor included in the power circuit; a wireless communication device configured to wirelessly couple to a wireless communication device included in the personal protective equipment. The wireless communication device is configured to receive a wireless signal transmitted from the wireless communication device included the personal protective equipment, the wireless signal providing information concerning whether the user is wearing the item of personal protective equipment properly. The electrical isolation device operates to allow current flow in the at least one conductor when the information provided by the wireless signal indicates that the item of personal protective equipment is being worn properly by the user.

An electrical connectors housing for receiving a pair of mated electrical connectors designed to provide easy connection and prevent inadvertent disconnection of electrical connectors, comprises a male electrical connector housing member; a female electrical connector housing member configured to receive the male electrical connector housing member; and cam-lock couplings to lock together female and male electrical connector housing members.

An electrical connection covering apparatus is designed to protect from moisture a connection between a plug of one extension cord and a socket of another extension cord. A compressible and elastic diaphragm is used to form a seal around the cables of the extension cords where they enter the apparatus. The apparatus includes a housing that has at least one aperture. The diaphragm extends across the aperture. The diaphragm projects inwardly with respect to an interior surface of the housing. The compressibility and elasticity of the diaphragm material is greater than that of the housing material.

A power adapter, comprising an adapter body, a power cord and a snap-fitting cover, the adapter body is provided with a socket, the power cord is provided with a plug plugged in and connected with the socket, and the snap-fitting cover includes the snap-fitting portion and the fixing portion, the fixing portion is movably connected to the end of the adapter body, the snap-fitting portion is provided with a groove which is shapely matched with the plug, and a groove is snap-fitted to the outer side of the plug. The snap-fitting cover is connected with the plug and the adapter body at the same time to retain the plug and the adapter body, and the plug is not easily disengaged from the socket of the adapter body under the external forces, thereby making the use of the power adapter more stable and reliable.

A device is disclosed for use with a detachable power cord having a plug. In certain embodiments, the device includes a receptacle configured to receive the plug, a circuit configured to determine a maximum operating parameter of the detachable power cord, and a controller configured to operate a function of the device based on the determined maximum operating parameter of the detachable power cord.

An electrical plug fastener or retention mechanism comprising a system of binding or securing electrical plugs or other connectors to avoid unintentional or accidental disconnection. The retention mechanism comprises a means for connecting to a first cord and a second cord. The retention mechanism is hinged and comprises a clamp. The clamp further comprises a clip that can also engages the first or second cord.

An electrical plug fastener or retention mechanism comprising a system of binding or securing electrical plugs or other connectors to avoid unintentional or accidental disconnection. The retention mechanism comprises a base for connecting to a first cord and a clamp for connecting to a second cord. The clamp and base may be connected via at least one extension bar. The base may be two separate halves with means for connecting to one of the power cords and the clamp may comprise a fixed half and a moveable half enabled to lock to the fixed half.

A system for securing an electrical connection is provided comprising a first half having a cord end and an open end and a second half, having a cord end and an open end. The cord ends of the first and second half each include a cord opening allowing a first and second cord to pass through the opening while holding a first and second electrical connector attached to each cord, and with the connectors engaged, the open ends include a means for securely attaching to each other thereby preventing disconnect of the engaged connectors.
