An elastic buckle is disposed in the housing and comprises two elastic pieces disposed oppositely, wherein each of the two elastic pieces is respectively provided with a first peg corresponding to the through hole. A slider is provided in the housing, a part of the slider extends into the housing and between the two elastic pieces of the elastic buckle, and the slider is configured for pushing the two elastic pieces of the elastic buckle and driving the first peg to insert into the through hole for limiting pins, which is inserted in the electrodes.

An apparatus configured for use with a first power cord, a second power cord and safety glasses including a first wireless communication device. The apparatus includes at least one line conductor, an electrical isolation device configured to prevent current flow in the at least one line conductor, a second wireless communication device configured to wirelessly couple to the first wireless communication device and a body housing the electrical isolation device and the second wireless communication device. The body includes a collar configured to move in a direction parallel to the longitudinal axis while coupled to the body. The collar includes an interior wall that defines a hollow region sized and configured to receive at least a portion of the body therein, the collar configured to secure to one of the female electrical socket and the male electrical plug with the respective one of first power cord and the second power cord electrically coupled to the distal end of the body and the collar at least partially extended from the body in a direction of the distal end. The electrical isolation device is configured to allow current flow in the at least one line conductor when the information provided by the wireless signal indicates that the safety glasses are being worn by the user.

Disclosed are a power connector and a power line. The power connector includes a connector body provided with insertion slots, where contact pieces are arranged in the insertion slots, and at least one insertion slot is provided with an auto-locking assembly, which includes a latching piece provided with a through hole therein, and a chamfer is provided at a top end of the through hole. The connector body is provided with a platform configured to support the latching piece, a first pull plate is disposed at one side of the latching piece, a chamber is defined in the connector body at the side of the insertion slots, and the first pull plate is disposed in the chamber and is connected to one end of the latching piece. There is further disposed a spring in the chamber, a telescopic orientation of the spring aligns with an axis of each of the insertion slots, a first end of the spring is connected to the first pull plate, a second end of the spring is connected to the connector body, and an inclined limiting plate is disposed on the platform. The first pull plate is connected to a second pull plate, and the second pull plate is partially disposed outside the connector body.

A smart breakaway electrical connector disconnects a powerline at a designed tensile load, detects the break, and wirelessly communicates the precise location of the break to repair dispatchers. Mating male and female housings hold the internal electrical connection points together. Locking arms pivotally connected to the female connector interlock by detent with the male connector and spring force on the locking arms is used to prevent disengagement of the detent until the design tensile force is exceeded. Photovoltaics combined with rechargeable batteries ensure power availability when the line is disconnected and utility power is unavailable.

A casing for connecting first and second power cords, the casing having a set of grip mechanisms with facing grip members that have serrated surfaces arranged to grip the first power cord and provide increased grip pressure in response to tension applied to the first power cord in order to resist the first power cord being pulled through the grip members and out of the casing.

An electrical receptacle unit with locking feature includes a receptacle adapted to be electrically connected to a source of electricity. The receptacle includes an electrical fitting having electrical contacts contained therein and/or extending therefrom, a socket surrounding the electrical fitting, and a plate disposed at a front of the socket. The electrical receptacle unit further includes a locking bracket that includes a central portion having first and second ends, a lock tab extending from a side of the central portion, and a pair of support arms, each extending forwardly from a respective one of the first and second ends. The locking bracket is pivotably secured to the plate, with at least a portion of each support arm positioned within a respective notched area of the plate. The locking bracket is pivotable relative to the plate between a first position, whereby a plug electrically seated within the socket is unobstructed, and a second position, whereby the plug electrically seated within the socket is obstructed from removal by the lock tab.

A connecting cable device includes a cable having two connectors attached to two end portions of the cable, and a lock device includes an elongated member, a casing formed on one end portion of the elongated member and having a chamber formed in the casing for engaging with the cable, a blocking member is engaged into the chamber of the casing for enclosing the chamber of the casing and for engaging with the cable and for retaining the cable in the chamber of the casing, and a fastening element is engaged with the casing and the blocking member for locking the blocking member to the casing and for preventing the blocking member from being disengaged from the casing.

An apparatus for locking electrical connectors together and for protecting such electrical connectors. A method of locking electrical connectors together.

A cord retainer is configured to be detachably disposed on an electronic device. The cord retainer includes a hook portion, a connection portion, and a clamp portion. The hook portion is configured to be fastened to the handle of the electronic device. The hook portion may be a tubular structure that extends along an extension direction. The connection portion is connected to the hook portion. The clamp portion is connected to the connection portion, and is configured to retain a cord attached on the electronic device. The clamp portion may be a plate structure that extends along an extension plane that is parallel to the extension direction.
