A male welding lead connector apparatus including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another. A method of locking a male welding lead connector to a female welding lead connector using a special male welding lead connector including a slidable member to block the male welding lead connector from rotating relative to a female welding lead connector when the two connectors are engaged with one another.

A cover for an electrical receptacle including a faceplate. The cover also includes a first transmission tab configured to be electrically connected to a first power line of the electrical receptacle and a second transmission tab configured to be electrically connected to a second power line of the electrical receptacle. Additionally, the cover includes a device (such as a light source, circuit, port, or sensor) in communication with the first transmission tab and the second transmission tab.

A system for sealing a terminated solar cable, the system including: a solar cable; a connector terminating the solar cable, the connector including a locking feature; and a plug including a locking feature. When the locking feature of the plug engages the locking feature of the connector to lock the plug and the connector in a locked state, the solar cable is sealed to provide safety from voltage and protection from dust and liquid.

An outlet enclosure for enclosing an electrical outlet to cover the electrical outlet and its electrical socket. The outlet enclosure includes a base plate and an outlet cover or holder which wraps partially around the electrical outlet to allow access to the electrical socket. The outlet cover or holder includes tracks extending in a vertical direction along its outer surface. An outer cylindrical cover wraps completely around the outlet cover or holder. The outer cylindrical cover slides vertically via the tracks over the outlet cover or holder from a lowered position fully enclosing the outlet cover or holder to a raised position exposing the electrical socket to allow access to the electrical outlet so that a plug can be inserted into the socket of the electrical outlet. When the outer cylindrical cover is lowered, it protects the electrical outlet from exposure to the elements.

A port protection device includes a blocking element movement subsystem that may be coupled to a port that defines a port entrance, and a port entrance blocking element connected to the blocking element movement subsystem and defining airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem allows the port entrance blocking element to be positioned in a port protection orientation immediately adjacent the port entrance such that airflow is restricted to entering the port via the airflow aperture(s). When the blocking element movement subsystem is coupled to the port, the blocking element movement subsystem also allows the port entrance blocking element to move from the port protection orientation to a cable connector orientation in response to engagement with a cable connector so that the cable connector may move through the port entrance to connect to the port.

A wall-mounted electrical-connector-engaging assembly for axial engagement with an electrical connector, the assembly including (a) a wall-surface adapter having front and back faces and attached to a wall over an opening in the wall and (b) a backcap. The adapter back face has a plurality of wire-connection points for installation of a corresponding plurality of wires, and the adapter front face has a plurality of slidably-engaging electrical connection points for engagement in at least an axial direction with the electrical connector. The backcap surrounds the plurality of wire-connection points and adjacent portions of the corresponding plurality of wires connected thereto, and includes a twist lock for installation on the wall-surface adapter.

A housing cap for closing an opening of a housing part includes a cover section covering the opening, a stop projecting away from the cover section, and a fastening element affixing the housing cap to the opening.

There is provided a connector including: a first connector; and a second connector. The second connector includes: a cover having a cover portion that covers a front surface opening of a first housing, a rotation shaft that rotatably supports the cover portion between a position where the cover portion covers the front surface opening and a position where the cover portion does not cover the front surface opening, and an abutted portion with which a protruding portion of the first housing abuts; and a slide mechanism that slides the rotation shaft toward the first connector in response to pressing the first housing to a second housing. After the rotation shaft is slid toward the first connector with the slide mechanism, the protruding portion presses the abutted portion such that the cover portion is rotated to the position where the cover portion does not cover the front surface opening.

There is a connector including: a first connector; and a second connector that has a cover configured to cover a front surface opening of a housing and a biasing member that biases the cover to a position where a cover portion covers the front surface opening. An opening edge of the front surface opening includes an inclined plane that intersects with a connector fitting direction and that is parallel to a rotation axis of the cover, the inclined plane intersecting at an obtuse angle with a straight line that extends from an opening edge end portion of the front surface opening and that orthogonal to the rotation axis. The connector is designed to rotate the cover to a position where the cover portion does not cover the front surface opening in response to a protruding portion of the first connector pressing a pressed portion of the cover.

A power connector includes a terminal block holding terminals in terminal channels with terminating ends configured to be electrically coupled to corresponding wires at separable interfaces. The power connector includes a rear insert covering the terminating ends of the terminals having wire ports configured to receive the corresponding wires during a wire poke-in process. The power connector includes biasing members associated with the terminals each including a pusher configured to be biased against the wire to push the wire into direct physical contact with the separable interface of the corresponding terminal. The power connector includes a release mechanism includes a plurality of pusher release elements. The release mechanism is actuated to release the pushers of each of the biasing members from the corresponding wires.
