A quick clip assembly for a strap element of an electrical receptacle is provided that expedites mounting of a wall plate to an electrical receptacle. The strap element is connected to an electrical receptacle and has an opening therein to receive a fastener. A resilient member is connected to the strap element such that a free end of the resilient member overlies the strap element opening. The free end of the resilient member flexes and engages the fastener inserted through the strap element opening without substantial rotation.

A contact termination member for an electrical receptacle is provided that has a base. A first spring arm is connected to the base and has a first free end. A second spring arm is connected to the base and has a second free end. The first and second free ends are adapted to engage a wire received by the contact termination member. The first and second free ends are non-parallel. The first and second spring arms engage the inserted wire to securely retain the wire within the contact termination member.

An electrical assembly is constructed for mounting to an electrical box or other support surface. The electrical assembly includes a non-metallic body that supports an electrical device such as an electrical receptacle that is surrounded by a non-metallic collar. A metal sleeve surrounds the collar such that the sleeve is electrically insulated from the electrical device by the collar. The sleeve includes a coupling member such as external threads for mating with complementing threads of a mating electrical device to provide a secure coupling to obtain a watertight rating.

A set of grounded and isolated duplex electrical receptacle assemblies includes interchangeable dual female bodies, interchangeable socket bases, interchangeable right, left and middle contact members, and interchangeable support bridges for assembling either a grounded or an isolated receptacle assembly. In the isolated assembly, an insulator plate is fitted between the support bridge and the middle contact member to electrically isolate one from another to thereby prevent electrical engagement therewith.

A switched electrical device adapted to be coupled to a complementary locking type electrical connector by initial relative axial movement therebetween and subsequent relative rotational movement therebetween. The switched electrical device includes a housing with an inlet opening for receiving the complementary electrical connector, a rotatable locking type electrical connector with a set of electrical contacts for engaging the electrical contacts of the complementary electrical connector, a switch mounted within the housing for selectively supplying electrical energy to the set of electrical contacts of the electrical connector, an operating handle for moving the switch between 'on' and 'off' positions, and an interlock mechanism for releasably locking the switch. The interlock mechanism selectively locks the switch in its 'off' position so that it cannot move to its 'on' position, until after the complementary electrical connector has been inserted into said opening and rotated to a locked position. The interlock mechanism also prevents removal of the complementary electrical connector from the inlet opening until the operating handle has been moved to its 'off' position, which disconnects power to the electrical contacts of the switch connector and the electrical contacts of the complementary connector.

A first rotatable locking type electrical connector having a polarizing sleeve with a detent and a first set of electrical contacts for electrically engaging a second rotatable locking type electrical connector having a complementary polarizing sleeve with a complementary detent and a second set of electrical contacts. In the preferred embodiments, the polarizing sleeve of the first electrical connectors has at least one key, preferably two keys, while the polarizing sleeve on the second electrical connector has a complementary slot or slots for receiving the key or keys of the first electrical connector. Each of the slot of the second electrical connector is arranged to receive a key of the first electrical connector so that the first and second electrical connectors can be coupled together by initial axial movement and subsequent rotational movement. Preferably, the detents are formed on the keys and within the slots for holding the electrical connectors against unintentional movement. Preferably, one of the detents is formed by alignment indicia, which indicates when the key and slot of the electrical connectors are properly aligned for axial movement and subsequent rotational movement.

A male electrical plug assembly includes an elongated body, terminal holder and terminal retainer made of an insulating material. The body has locating elements and locating passages aligned with the locating elements. The terminal holder fits over an opposite end portion of the body and has cavities formed thereon and slots defined therein aligned with the cavities. The cavities and slots are alignable with the locating passages and the locating elements. The male plug assembly also includes electrical terminals disposed in the cavities and elongated electrical contact elements mounted to the locating elements and extending through the locating passages of the body and through the slots and through the cavities of the terminal holder and through the terminals disposed in the cavities and into the terminal retainer.

A lockout device for enclosing and inhibiting unauthorized access to an electrical connector attached to an electrical cable has first and second identical joinable shell portions each with a concave interior so that when the shell portions are joined the interiors define a cavity for receiving an electrical connector. Each shell portion has a hinge pin and a hinge clevis for connection to a hinge clevis and a hinge pin, respectively, on the other shell portion to pivotally join the shell portions so that they are pivotable between open and closed positions. Male and female latch members engageable with similar members on the other shell portion are provided to hold the shell portions in the closed position. Arcuate recesses at opposite ends of the said shell portions form a circular opening, when the portions are joined, to permit a cable attached to the connector contained in the cavity to extend out of the housing.
